FORD ELLIOTT, Judge,
dissenting:
I must respectfully dissent. The majority’s opinion has effectively driven the expert from the courtroom in cases involving the sexual abuse of children. This result was not mandated by precedent, but instead stems from the majority’s misreading and misapplication of the holdings of our supreme court.
Significantly, the supreme court has never expressly overruled the opinion of this court in Commonwealth v. Baldwin, supra. Contrary to the majority’s assessment, that court had the opportunity to overrule Baldwin in deciding Commonwealth v. Davis, supra, and instead the court, in a footnote, stated that Baldwin was disapproved only insofar as it conflicted with the Seese and Davis decisions. Therefore, I would find that Baldwin is still valid authority for the proposition that behavioral and psychological characteristics of child sexual abuse victims are proper subjects for expert testimony when such are relevant to an issue in the case and the expert’s opinion does not assess or evaluate the credibility of the particular victim. I, therefore, would affirm the trial court’s reliance on Baldwin for the admission of the expert testimony in this case, finding that prompt complaint was at issue and that the expert’s testimony was highly relevant on that issue and did not offer an expert opinion on the veracity of the victim.
THE CASE FOR EXPERT TESTIMONY
The standard in Pennsylvania for the admission of expert testimony as enunciated by Mr. Justice Flaherty in Commonwealth v. Seese, supra, is that, “[ejxpert testimony is *292admissible in all cases, civil and criminal alike, when it involves explanations and inferences not within the range of ordinary training, knowledge, intelligence and experience.” 1 512 Pa. at 442, 517 A.2d at 921, (emphasis supplied) (citations omitted).
The use of expert testimony in child sexual abuse cases meets this criteria. The reason is simple. The immediate effects, long term impact and psychological trauma of sexual abuse on children are not, gratefully, matters within the common knowledge, information or understanding possessed by an ordinary juror. Not even a parent, who readily might recognize that a young child is exhibiting strange or unusual behavior, would associate such behavior with something as abhorrent as sexual abuse. How can we assume that jurors are vested with this understanding by virtue of their oath. Therefore, I take particular exception to the majority’s conclusion that:
[jjurors are human and may be unduly impressed by an expert, his credentials, and ultimately his opinion, even though, upon reflection, they would realize that in the particular field under discussion they are as much at home as the expert.
Majority opinion at 289 (citation omitted).
Expert testimony, which specifically addresses the psychological dynamics of sexual abuse of children and their behavioral patterns as victims, is vital in many cases. As discussed by Judge Beck in Baldwin,
[tjhe foregoing decisions support our conclusion that expert testimony such as that offered by Battinieri does not improperly invade the jury’s prerogative. As one commentator has noted:
The argument that such psychological testimony is prejudicial because it bears on the credibility of a witness, and thus invades the province of the jury, is *293simply wrong. Expert testimony cannot “invade the province of the jury” unless the jury is instructed that it must agree with the expert’s assessment.
Baldwin, supra, 348 Pa.Super. at 376, 502 A.2d at 257.
There is a growing body of reliable scientific data to support the fact that the sexual abuse of children embodies psychological and societal components that are not generally within the common understanding and experience of lay observers. The nature of this abuse is often subject to myths and stereotypes. While a juror easily might comprehend that sexual abuse can have an impact on a child psychologically, a juror without some type of expert analysis, would not be able to understand the behavioral and psychological manifestations of this impact. As one commentator noted,
[ejxpert psychological testimony concerning a defendant’s sanity is often esoterically expressed in psychological jargon that is far removed from the common experience of the ordinary juror. By contrast, most types of nontraditional scientific evidence are much closer to the common understanding of the ordinary juror, yet, may fall beyond the. common experience of jurors. Nontraditional psychological evidence often deals with circumstances that jurors probably suspect involve peculiar psychological consequences not associated with everyday existence. Yet jurors are without sufficient information to have any great insight into what those peculiar consequences might be.
McCord, Syndromes, Profiles and Other Mental Exotica; A New Approach to the Admissibility of Nontraditional Psychological Evidence in Criminal Cases. 66 Or.L.Rev. 19, 30-31 (1987).
Perhaps the most troublesome aspect of the majority’s decision is that without regard to the content or purpose for which the expert testimony is offered, it finds any expert testimony on the behavioral or psychological dynamics of child sexual abuse inadmissible because it “bolsters the credibility of the victim,” and thereby invades the province *294of the jury. However, can it be denied that the use of expert testimony in any case will either bolster or impeach the testimony of other witnesses. As stated in Baldwin,
[t]he fact that the jury, if it believes the expert’s testimony, may draw inferences which would tend to bolster the victim’s credibility does not make the evidence inadmissible. It is a commonplace fact that the testimony of one witness may tend to corroborate another. Far from being improper, this is normal and is good trial strategy. (Much expert testimony will tend to show that another witness either is or is not telling the truth.... This, by itself, will not render evidence inadmissible).
Baldwin, supra, 348 Pa.Super. at 376-77, 502 A.2d at 257 citing State v. Middleton, 294 Or. 427, 657 P.2d 1215 (1983).
An application of the reasoning employed by the majority could result in the exclusion of expert testimony in many cases on the basis that its effect is to bolster, support or enhance the credibility of one witness or another. The following types of expert testimony are prime examples: (1) the expert who testifies in a drug possession case regarding the validity of the “drug courier profile” utilized by the arresting officer; (2) a medical expert who testifies that vaginal lacerations and adhesions are consistent with a complainant’s version of a rape; (3) the psychiatrist who testifies in a rape case that a mentally retarded adult victim is incapable of forming consent; (4) the ballistics expert who testifies that an injury inflicted on a victim is inconsistent with the defendant’s story of self defense; (5) the expert who testifies in a child abuse case that the injuries inflicted upon the victim could not be the result of an accident; (6) the expert who testifies regarding the effects of drugs or alcohol on a person fitting the defendant’s weight and size as supporting the arresting officer’s observations; and, (7) the expert who testifies regarding diminished mental capacity.
In the Seese and Davis decisions, the supreme court specifically disapproved, in this jurisdiction, the use of expert testimony which presumes to pass directly on the *295veracity of a particular witness. Specifically, Seese prohibited the expert from evaluating the credibility of the victim, and Davis prohibited the expert from evaluating the veracity of the class to which the victim purportedly belonged. The Seese and Davis decisions carve out exceptions to the general principle that expert testimony is admissible in the prosecution of child sexual abuse cases. They adhere to the long established rule that an expert may not evaluate the testimony of witnesses as to credibility, for to do so would invade the province of the trier of fact. Such direct testimony on credibility supplants the jury’s function. Justice Flaherty characterized the limited nature of the holding in Seese, when he stated:
[although opinion evidence is not to be permitted on the issue of a witness’ credibility, there remain, of course, all of the traditional methods for developing, or attacking a witness’ credibility.
Seese, supra 512 Pa. at 444, 517 A.2d at 922.
This court, however, rather than adhering to the exceptions carved out by the supreme court, has instead, with broad strokes, obliterated the fine lines drawn by that court, and in effect, rendered inadmissible relevant, material, probative and scientific testimony of an expert merely because it supports the credibility of an alleged victim. I would suggest to the contrary that within the context of a child sexual abuse case, it may impede the function of the jury not to admit such testimony. To further provide perspective in this area, an examination of the role of the expert in child sexual abuse prosecutions is instructive.
THE ROLE OF THE EXPERT
In analyzing the caselaw, one author has gleaned five basic roles which the expert may assume when testifying in a sexual abuse case.
One jurisdiction permits the psychologist to testify as to the credibility of the child’s testimony regarding the occurrence of the misuse and the identity of the offender. Because the child is likely to be a witness, the expert, in *296effect, is employed to testify as to the credibility of another witness, the expert assuming the role of adviser to the jury on the weight that they should place upon the testimony before them. Commentators have identified this role as the liberal view, and one that has not been widely adopted.
Another approach permits the expert to testify regarding the results of a psychological evaluation of the child and to determine whether the psychological status of the child is consistent with having been subjected to sexual misuse by an adult. The evaluation itself may include a determination as to whether the child’s behavior patterns are consistent with a syndrome or a diagnosis. This role is directly analogous to the approach taken by most courts with regard to the admission of testimony by a treating physician. The expert will identify symptoms of psychological injury and will report the behavior patterns observed during the examination of the child. Further, the expert will present a professional opinion as to whether these observations are indicative of a diagnosis or are consistent with the occurrence of a particular event. The expert thereby indirectly supports or impeaches the veracity of other witnesses.
A third approach calls upon the expert to present the behavior patterns and psychological symptoms associated with sexual misuse, without having evaluated the victim. The expert may respond to a hypothetical question that incorporates specific facts of the case. This role for psychological experts in child sexual misuse cases is a variation of the approach that many jurisdictions take with regard to traditional medical expert testimony. Rather than serve as a gatherer of facts, as in the second role discussed above, the expert applies scientific knowledge to either the hypothetical facts presented or to the facts admitted into evidence.
The fourth approach is similar to the third in that the expert does not evaluate the child. Under this scheme, the expert’s testimony is restricted to a discussion of *297general principles, leaving the application of these principles to the trier of fact. This approach is essentially an educational model, in which the expert’s testimony educated the trier of fact.
The fifth and final approach allows the expert to present the child’s testimony, which was elicited by the expert under reasonably controlled conditions and preserved. The expert may assist the court in the interpretation of the preserved testimony when its meaning is not self-evident. The expert thus assumes the role of preserver of perishable testimony — a role that has been assumed by the experts and accepted by the courts sub silentio. This is a necessary subcomponent of the second role identified above. The clinical expert must elicit the child’s verbal and nonverbal behavior in order to evaluate the child. For this evaluation to be meaningful, the methods and conditions must be reasonably controlled. As presently conducted, however, this testimony is most often preserved in a haphazard fashion, subject to the need of the evaluator to support the evaluation.
Note, The Admissibility of Psychological Testimony in Cases Involving the Sexual Misuse of a Child, 42 U.Miami L.Rev. 1033, 1040-1042 (1988). See also, Note, Expert Testimony in Child Sexual Abuse Prosecutions: A Spectrum of Uses, 68 B.XJ.L.Rev. 155 (1988).
These roles represent examples of the varied content and purpose for which expert testimony might be offered in the trial of a sexual abuse case, and they also help to illustrate the limited nature of the Seese and Davis holdings. Our supreme court in these cases has prohibited the use of an expert, no matter what role that expert may assume, from assessing a witness’ ability to tell the truth.
THIS COURT’S EXTENSION OF SEESE AND DAVIS
Recognizing that Seese and Davis dealt with express testimony regarding the alleged victim’s ability to verbally communicate the truth, the superior court has gone further and held that expert testimony on the behavioral dynamics *298of sexual abuse equally invades the province of the fact-finder.
In cases where lay witnesses, perhaps a parent or teacher, were permitted to take the stand and testify as to the child’s change in behavior following an alleged incident of abuse, the expert was prohibited from pulling together the behavioral testimony of the lay witnesses and giving the jury some correlation or assessment of the questioned behavior. Commonwealth v. Emge, supra; Commonwealth v. Higby, supra.
In Commonwealth v. Gibbons, supra, this court agreed with the trial court that the expert's testimony was “relevant and probative in that the jury could infer that gaps and inconsistencies in the victim’s testimony stemmed from the psychological dynamics of incest rather than from fabrication or fantasy.” Id. 383 Pa.Super. at 299, 556 A.2d at 916. This court went on to point out that, unlike in Emge, supra, the psychologist did not testify that the accusing child’s behavior matched the behavior of known victims of sexual abuse. Nevertheless, citing Emge, the court concluded that the probative value of the expert’s testimony clearly was outweighed by the prejudicial impact of admitting it. No further explanation was given for this conclusion.
In Commonwealth v. Dunkle, supra, a case very similar to the instant case, this court held that, where the child delayed in reporting the incident and failed to recall certain details of the alleged abuse, her testimony must stand alone before the jury, even though she may not be able to explain her behavior. The court determined that any attempt to introduce expert testimony, which dealt with the fact that children, sexually abused, sometimes delay in reporting the incident and sometimes are unable to recall exact dates and times because of the trauma associated with the event, is in violation of the Seese and Davis holdings. To admit such behavioral testimony, the court reasoned, would thereby allow the jury to accept the victim’s version of the facts. Dunkle, supra, 385 Pa.Super. at 325-26, 561 A.2d at 9.
*299This line of decisions tacitly, has eliminated the use of expert testimony in abuse cases no matter in what form or for what purpose it is offered. It has lumped all types of such testimony into one category, leaving the prosecution, defense counsel, and the trial court without any guidelines for determining admissibility. I would be inclined to agree with my colleagues on the inadmissibility of such testimony if the objections were grounded more soundly on relevancy or on the particular use of, or necessity for, such testimony at trial or on the qualifications of the expert or even the validity of the research data. Absent such objections, however, the jury is entitled to the evidence.
Moreover, the introduction of such expert testimony offered in child sexual abuse cases is always subject to cross examination, impeachment, and cautionary instructions.2 These are the protections afforded to a defendant to insure that the proper weight is given to any expert testimony by the jury.
THE IMPACT OF GALLAGHER
The majority would argue that the supreme court’s decision in Commonwealth v. Gallagher, supra, has extended that court’s Seese and Davis holdings now to prohibit all expert psychological syndrome testimony including testimony regarding the behavioral patterns of sexual abuse victims on the basis that such testimony bolsters the credibility of the victim.
I admit to some difficulty in denying that the supreme court’s treatment of the rape-crisis syndrome in Gallagher might have application to other types of syndrome testimony including the child sexual abuse accommodation syn*300drome.3 As discussed by Judge Tamilia in his dissent in Commonwealth v. Smith, 389 Pa.Super. 626, 567 A.2d 1080 (1989), a syndrome is a collection of symptoms, the manifestation of which may vary from case to case. A syndrome does not represent a diagnosis and therefore its use as substantive evidence of the occurrence of a particular event is always subject to scrutiny.4
In Gallagher, the expert testified that she examined the victim and diagnosed the victim as suffering from rape trauma syndrome. She further testified that she believed the syndrome affected the victim’s ability to identify the assailant. The supreme court determined that this testimony improperly enhanced the victim’s credibility in the eyes of the jury which was impermissible. See Commonwealth v. Cepull, supra, wherein Gallagher is distinguished on this basis. However, the court, specifically declined to reach the issue of whether evidence on rape trauma syndrome was sufficiently reliable to be admissible generally. Considering once again the roles of an expert which were reviewed earlier, the holding in Gallagher appears to do no more than assail the use of an expert to offer syndrome testimony as clinical diagnosis. In effect, the second approach to the role of an expert which permitted the testimony of the expert regarding the results of a psychological evaluation and the determination of whether the psychological status of the victim is consistent with having been subjected to the rape trauma has now been disapproved in this jurisdiction. The issue of whether an expert may testify generally as to behavior patterns and psychological symptoms associated with rape trauma syndrome when offered for another purpose was not decided by Gallagher. I consider this conclusion borne out by the supreme court’s *301treatment of another psychological profile type — the battered woman syndrome in Commonwealth v. Stonehouse, 521 Pa. 41, 555 A.2d 772 (1989). While I agree with the majority that the result in Stonehouse was the grant of a new trial based on ineffective assistance of counsel in failing to request an adequate jury instruction, there is little question that the lead opinion authored by Justice Larsen, and joined in by Justice Papadakos and former Justice Stout, would have found counsel ineffective for failing to present expert testimony on the battered woman syndrome. Justice Zappala in his concurrence joined in by Justice McDermott, while choosing not to reach that issue stated the following:
[although the issue was addressed by amici, the appellant has made it clear that appellant’s position on the self-defense issue is not to be mischaracterized as a failure to raise the ‘battered woman syndrome’ issue. While I recognize the import of this issue, I believe its resolution is best left to a time when the issue is squarely before us.
Stonehouse, supra, 521 Pa. at 66-67, 555 A.2d at 785. There is nothing in the majority or concurring opinion which would have precluded defense counsel on remand from offering expert testimony on the battered woman syndrome in defense of the case, and in fact three members of the court already had found prior counsel ineffective for not doing so.5 In the interests of justice and judicial economy, if Gallagher so clearly forbade the introduction of psychological profile testimony under all circumstances then surely one of the justices of our supreme court would have so indicated. Having stated thus, if an adult defendant has the right to have a psychological condition explained to the jury by an expert, what logic deprives a child victim of this same opportunity to have her story heard. The injustice worked by the majority’s holding today is further highlighted by the notion that a defendant now might offer the very same expert testimony, which we preclude the prosecution *302from introducing, to establish that his actions were the result of his own experience of having been victimized by sexual abuse as a child.
THE TESTIMONY OF DR. DEJONG
Turning to the role of the expert in the instant case and examining the nature of his testimony and the purpose for which it was offered, I would find Dr. DeJong’s testimony to represent one of the purest examples of the proper use of expert testimony in an abuse case.6 And I readily would admit that the effect of the testimony was to enhance the credibility of the victim. As discussed by the majority, Garcia relied upon the alleged victim’s delay in reporting the abuse as a central element of his defense. Counsel engaged in extensive cross-examination of the victim to highlight this fact and in its closing to the jury the defense vigorously argued the delay issue. Prompt complaint was an issue for the jury to consider in assessing and weighing the testimony of the child victim. Thus, the trial judge instructed the jury:
[a]nother aspect of sexual assault cases concerns what is known in the trade as prompt complaint.
Again there used to be reasonings and philosophies years ago that because of a particular heinous nature a sexual assault is the type of incident that immediately demanded an outcry from the person who was the alleged victim. Hence, the development of a theory called prompt complaint.
Notes of Testimony, N.T., 10/16/87 at 123-124. Obviously, the jury is entitled to all available information in confronting this issue. The trial judge, therefore, properly permitted the statistical testimony of Dr. DeJong to be considered by the jurors in order to aid them in following his instructions that “delay or failure to make prompt complaint are factors bearing upon the believability of [‘the witnesses’] testimony and must be considered by you in light of all the *303evidence in the case.” Id. at 126. I cannot agree with the majority that Dr. DeJong’s testimony was the same as that prohibited by the supreme court in Seese, Davis or Gallagher.
Following the victim’s testimony, Dr. DeJong, a pediatrician with expertise in sexual abuse, testified to the possible reasons for the lack of physical trauma to the victims. This was one of the issues the jury had to confront. He •further testified as to the statistics he compiled as Director of the Pediatric Sexual Assault Follow-Up Program at Jefferson Hospital. These statistics showed varying delays between the time that the alleged sexual abuses occurred and the time when they were reported. Some children reported alleged sexual abuse immediately, others delayed. He did not, however, offer an opinion as to the accuracy or validity of the complaints he recorded.
The majority holds that this expert testimony was improper in that it was an attempt by the Commonwealth to have the jury adopt an expert’s opinion that delay was a normal occurrence in sixty-six percent of child sexual abuse cases. This is not quite accurate. Dr. DeJong did not render an opinion as to what was normal or abnormal in sexual abuse cases. He testified that two-thirds of the children who reported alleged incidents of sexual abuse did so at least twenty-four hours after those alleged incidents occurred. He did not attempt to interpret those statistics for the jury nor attach any significance to them.
Additionally, such testimony was not being offered to establish the occurrence of a fact of consequence, but rather to assist the trier of fact in weighing the probative value of a circumstantial fact. One commentator has explained, *304postponing disclosure of the sexual misuse for a period of months or years. A juror is likely to be incredulous upon hearing a defense attorney elicit from the prosecution’s chief witness, the child victim of misuse, that the child delayed for an extended period of time before reporting the abuse to anyone. Common experience teaches us that when a child suffers an injury the child will tell an adult almost immediately. Therefore, testimony of delay in reporting an abusive event would serve as an indirect impeachment of the child’s veracity. The prosecutor may call an expert to address this perception. The expert will testify that a delay in reporting an incident of sexual misuse is a common occurrence among victims of sexual assault. The defendant, through his elicitation of testimony regarding delay in the reporting of the incident of sexual misuse opened the door to the admission of the prosecution’s expert testimony. The defendant placed in issue the proper interpretation of the elicited circumstantial fact: Whether there exists a stronger correlation between delay in reporting and fabrication than between delay in reporting and telling the truth. The expert’s role in such a case is to provide an opinion, based upon both the statistical studies and their own clinical experience with patients other than the victim, as to which correlation has more merit.
*303[t]he purpose of an expert’s testimony with respect to scientific information is to provide information that is beyond the common experience of the trier of fact and that will assist it in the determination of the probative value to be assigned to a circumstantial fact that bears upon a fact of consequence. An example is a child’s
*304Expert Psychological Testimony, supra at 1055-1056.
The use of expert testimony in this manner has been approved in numerous other jurisdictions.7 As suggested *305by one writer, such testimony has an important and relevant place in the courtroom:
[t]he defense in child sexual abuse cases often highlights some unusual aspects of the victim’s behavior. These aspects typically include delays in reporting, inconsistent and partial disclosures, and recantations. The defense generally raises these issues during cross-examination of the victim, or perhaps during cross-examination of other state witnesses such as police officers or child protective service workers. This type of cross-examination is often very effective if the prosecutor does not take steps to rehabilitate these witnesses. Jurors often do not understand the dynamics of a sexually abusive relationship. They do not understand that children usually do not report sexual abuse immediately. In addition, any partial disclosure or recantation mentioned by the defense gives credence to the view, held by many prospective jurors, that children fabricate stories of sexual abuse.
When faced with this type of defense, the prosecutor should consider using expert testimony either in the case in chief, or in rebuttal. This form of testimony is fundamentally different from the expert diagnosis of child sexual abuse syndrome referred to earlier in this article. The testimony of an expert in this context is more general, and is designed to provide the jury with an analytical framework within which to evaluate the child victim’s testimony. In essence, the testimony is being offered to show that the victim’s behavior, while appearing to be inconsistent, may in fact be consistent with sexual abuse. However, the expert in this case is not being asked for an opinion about whether the specific child in this case is an abused child.
*306Prosecutors have successfully admitted testimony from experts on the subject of delayed and incomplete disclosure. For example, in People v. Dunnahoo [152 Cal.App.3d 561], 199 Cal.Rptr. 796 (Cal.Ct.App.2d 1984), the defense pointed out that the two victims did not immediately tell the police about the acts committed on them by the defendant. The prosecution then used two police officers, qualified as experts in the field of child molestation, who testified that sexually molested children find it quite difficult to talk about sexual abuse. The appellate court held that this was appropriately admitted expert testimony. Similarly, in People v. Benjamin, R. [103 A.D.2d 663], 481 N.Y.S.2d 827 (1984), the court approved the admission of expert testimony concerning why a victim of sexual abuse is often reluctant to reveal the crime, particularly if it occurred in a family setting. The court pointed to the fact that the defense raised the issue of delayed reporting during the cross-examination of the victim. Moreover, the court noted that the testimony was of a general nature and did not amount to an expert opinion that in fact this specific child was a victim of molestation. In State v. Middleton [294 Or. 427], 657 P.2d 1215 (Ore.1983), prosecutors successfully admitted expert testimony that sexual abuse victims often recant their original disclosure.
The prosecutor should be on firm ground in offering this testimony, as it is admissible in most states. The expert should be counselled by the prosecutor prior to trial not to opine that the specific child is a victim of molestation. Testimony from experts that delays in reporting, incomplete disclosures, and recantations are not inconsistent with abuse should provide the jury with an appropriate knowledge of the dynamics of child sexual abuse. As one commentator has noted, the prosecution’s use of expert testimony in this way is in keeping with the theory of expert witness rules and facts. See R. Roe, ‘Expert Testimony in Child Sexual Abuse Cases,’ from Papers from a National Policy Conference on Legal Re*307forms in Child Sexual Abuse Cases, American Bar Association, (1985).

CONCLUSION
Admittedly, the views expressed in this dissent are not new. Rather, they have been expressed previously by other members of this court with great clarity and eloquence. See Commonwealth v. Purcell, 403 Pa.Super. 342, 589 A.2d 217 (1991), (Dissenting Opinion by Beck, J.); Commonwealth v. Cepull, supra, (Opinion by Tamilia, J.); Commonwealth v. Dunkle, supra, (Kelly, J. dissenting); Commonwealth v. Thek, 376 Pa.Super. 390, 546 A.2d 83 (1988) (Opinion by Kelly, J.); Commonwealth v. Smith, supra, (Dissenting Opinion by Tamilia, J.); Commonwealth v. Pearsall, 368 Pa.Super. 327, 534 A.2d 106 (1987), (Opinion by Kelly, J.); and, Commonwealth v. Emge, supra, (Dissenting Opinion by Brosky, J.).
The admissibility of non-traditional psychological evidence is a new and uncharted evidentiary area in many jurisdictions. Hence, the strong advocacy by several members of this court that we proceed at a more measured and calculated pace in defining admissibility standards for such evidence.8 Certainly, such an effort would benefit far more from a review on a case by case basis, rather than, at this early date, the establishment of blanket prohibitions.9 This is particularly so since our supreme court’s rulings on the admissibility of such evidence have not been as sweeping.
Without question, expert testimony on the behavior patterns and psychological dynamics of sexual abuse victims can be very prejudicial. While, we have a grave responsibil*308ity to address the many legitimate concerns regarding the use of expert testimony in this area, we also must not ignore its tremendous benefits to the truth determining process. This responsibility becomes all the more critical when such expert testimony is offered to aid the trier of fact in cases involving society’s most vulnerable victims, our children. If we can determine on sound evidentiary grounds, that expert testimony is reliable, relevant, material and probative, can we afford to keep it from the jury in a case of child sexual abuse. Should not our inquiry be focused more on weighing the probative value of such testimony against its prejudicial impact in any given case.
I agree with the majority that our primary concern is to do justice. But a necessary part of that mandate involves providing a jury with the best possible evidence to allow it to decide a case correctly. Undeniably, there is presently a climate of hysteria in our society which makes the possibility of false accusation a matter of grave concern. Therefore, for the protection of both the accused and the child, the Commonwealth must be required to exercise its discretion with great caution when deciding whether to prosecute such cases. However, once the decision to prosecute is made, we must not abandon the child in the courtroom.
