Instructions: 
Use non-professional language and address each part separately to describe your protocol. Attaching sections of a grant application 
or proposal is not an acceptable substitute. Provide sufficient information for effective review by all members of the IRB, including 
non-specialists. Define all abbreviations and terms that are not part of common language. 
 
 
Describe the objective(s) of the proposed research: 
Describe why this research project will be carried out. Clearly state the overall objectives, specific aims, hypotheses (research 
questions), and rationale for performing the study. 
The overall objective of this study is to explore different ways to accelerate learning to improve memory performance. 
 
The first aim of this study is to investigate the effects of transcranial Direct Current Stimulation (tDCS) stimulating the 
greater occipital nerve (more specifically the C2 area) during a verbal paired-associate learning task and to determine if 
tDCS targeting the C2 may be used as a way to enhance brain plasticity during an associative memory task to accelerate 
learning and to optimize associative memory performance. We hypothesize that participants who received real tDCS will 
have a better associative memory performance compared to participants who received sham tDCS. 
 
The second aim is to examine whether repeated retrieval practice can accelerate learning and enhance associative 
memory performance. By using two versions of the verbal paired-associate learning task, we want to investigate the 
influence of repeated studying and repeated retrieval practice on associative memory performance. We hypothesize that 
participants with repeated retrieval practice will have a better associative memory performance compared to participants 
without repeated retrieval practice. 
 
Describe previous studies that form the basis for the proposed research: 
Associative memory refers to remembering the association between two items, such as a face and a name or a word in 
English and the same word in another language. It is not only important for learning and for navigating daily life, but it 
is also one of the first aspects of memory performance that is impacted by aging and by Alzheimer׳s disease. For 
decades, neuroscientists have investigated associative learning and memory and ways to accelerate and enhance 
associative learning and memory. This knowledge contributes to a better basic understanding of learning and memory. 
 
In the last decade, non-invasive neuromodulation, such as transcranial direct current stimulation (tDCS), have been 
introduced to modulate cortical brain areas (Nitsche et al. 2008; Matsumoto et al. 2010; Nitsche and Paulus, 2011; 
Zaehle et al. 2011; Polanìa et al. 2011; Stagg and Nitsche 2011; Brunoni et al. 2012a) as well as the greater occipital 
nerve area (more specifically the C2 area) (Plazier et al. 2015). Transcranial direct current stimulation (tDCS) is a form 
of neurostimulation which uses constant, low current delivered directly to the brain or the occipital nerve area using two 
electrodes. TDCS has been proposed as a therapeutic procedure in various diseases (e.g. Hoy and Fitzgerald 2010; Zyss; 
2010; Benninger et al. 2010; Freitas et al. 2011; Brunelin et al. 2012; Brunoni et al. 2012b; Berlim et al 2013) and tDCS 
in healthy adults have demonstrated to improve cognitive and memory performance (e.g. Floel et al., 2008; De Vries et 
al., 2010; Fiori et al., 2011; Fregni et al., 2005), but few tDCS studies have investigated its impact on associative 
memory. By targeting the occipital nerve area we want to introduce a safer and easier-to-use non-invasive 
neuromodulation procedure. The greater occipital nerve is known to be connected to the locus coeruleus via the 
trigeminal nerve complex which is associated with enhancing brain plasticity. Therefore, we aim to increase our 
understanding of the effects of transcranial Direct Current Stimulation (tDCS) targeting the greater occipital nerve (C2) 
during an associative memory task and determine if tDCS may be used as a way to enhance brain plasticity during an 
associative memory task to accelerate learning and to optimize associative memory performance. 
 
Previous research has also emphasized the importance of repeated learning and repeated retrieval practice as a way to 
accelerate learning and enhance associative memory performance (Karpicke and Roediger, 2008). Therfore, in this study 
we will also examine the effect of repeated learning and repeated retrieval practice on associative memory performance 
by using two versions of an associative memory task 
 
 
What information do you expect to obtain and how will the obtained knowledge be applied: 
To investigate the effects of tDCS on associative memory performance, we will measure associative memory 
performance in a group that receives active tDCS and a group that receives sham tDCS. To examine the effect of 
repeated learning and repeated retrieval practice on long-term memory retrieval, we will use two versions of an 
associative memory task. Assessments will be done immediately after the learning phase as well as one week after to 
measure possible (long-term) effects on associative memory performance. 
PROTOCOL SUMMARY 

Page 5 of 18 
Last Revised 01/2016 
 
Associative memory performance will be measured using a computerized verbal paired-associate learning task, which 
includes Swahili-English vocabulary learning. We will base our task on an experiment published in Science by Karpicke 
and Roediger (2014) where all information is provided to conduct the two versions of the Swahili-English vocabulary 
learning test. 
 
The knowledge gained from this study will provide evidence as to whether or not tDCS is possible in accelerating 
learning and in improving associative memory and whether repeated testing can enhance associative memory.

The identification and recruitment of participants must be ethically and legally acceptable and free of coercion. Procedures used to 
recruit participants should be designed to reach diverse populations. For example, vulnerable participants, such as persons in nursing 
homes or institutions, should not be recruited merely for the sake of convenience. 
 
Recruitment Methods 
 Advertisement 
  Phone solicitations 
 Verbal scripts for face-to-face meeting 
  E-Mail 
 Letters to potential participants 
  Web-Based
 Other, please explain: Flyer 
Please describe the recruitment procedures including: 1) how participants will be identified; 2) the steps for recruiting 
participants; and 3) who will have responsibility for recruitment: 
1) We are recruiting healthy subjects between the ages of 18 to 35 years old for our study, which overlaps with the

opportunity to consider whether or not to participate in the study: 
Prospective participants who meet the preliminary inclusion/exclusion criteria on the flyer can contact the research 
personnel through the contact information on the flyer, if they are interested. They will be contacted by phone for more 
information about the study and they will be screened if they are still interested to participate in the study. If they are 
eligible, they have the choice to schedule for an appointment right away or to contact us back to schedule an 
appointment to give them more time to consider a possible participation in the study. Once scheduled, we will be sent 
an electronic copy of the Consent Form. This will allow prospective participants to read and gather any questions about 
the study at their own pace. Note: Prospective participants will be asked to sign the Consent Form only at the UTDallas 
main Campus 
Please describe the measures that will be taken to minimize the potential for undue influence: 
As standard lab protocol, we ask the following questions before any prospective participant signs the Consent Form: 
 
1 Can you tell me the main purpose of the study, and why you are involved? 
2. Can you tell me the main components of the study that require your participation? 
3. Do you understand that signing this Consent Form does NOT mean that you have been officially included in the study, 
but rather, inclusion into the study will be determined based on outcomes on additional screening measures? 
4. If you decide to not participate in the study at any time, what should you do? 
5. If you experience any discomfort or symptoms associated tDCS, what should you do?

Process of Consent 
Consider: a) the environment and location where informed consent will be solicited; b) the timing of the process (for instance the 
stress that may be associated with the situation); c) the involvement of someone other than the investigators to help explain the 
research; and d) opportunity for the prospective participants or their legal representatives to discuss participation in the research with 
family, friends, or their advisors before signing the consent form. 
 
Where will the consent process take place? 
a) all participants will sign the consent form in dr. Vanneste's lab in Green Hall GR 2.404 or in BSB 14.604 at UTD Main 
Campus 
How--and by whom--will it be determined whether the participants or their legally authorized representatives understand the 
information provided? This section should clearly document that the investigator has an adequate plan in place to assure existence 
of an acceptable level of comprehension before consent is documented. 
The study personnel who administer the consent form will follow strict lab protocol by asking the aforementioned 
questions about the study (see above on minimizing undue influence) to each participant before they sign the consent 
form 
 
 
Waiver of Informed Consent Process (complete only if you are requesting a waiver of consent) 
Explain why the use presents no more than minimal risk to the participants? 
 
 
 
Explain why a waiver of informed consent will not adversely affect the rights and welfare of the participants?

Mark one or more of the following that apply: 
 
 Interviews 
 Standardized assessments 
 Survey/questionnaire 
 Deception 
 Behavioral observation 
 
Describe each activity in which participants will be involved: 
Attach surveys, instruments, interview questions, etc. Describe the frequency and duration of procedures, psychological tests, 
educational tests, and experiments; including screening, intervention, follow-up etc. 
Participant’s Review of Inclusion/Exclusion Criteria: Prospective participants will initially review general inclusion and 
exclusion criteria about the study on the flyer where there is contact information to contact a researcher for more 
detailed information about the study. Interested individuals will be screened through a standard phone screen script. 
Their continued interest in the study confirms that they have met basic inclusion/exclusion criteria (via self-report). 
 
Administration of Consent Form: When the Consent form is administered, participants will have already acknowledged 
that they have met the criteria and have expressed continued interest in participating in the study. If, at that time, they 
feel that they do not meet the criteria, or have specific questions about these criteria, they will be asked to inform the 
research team member administering the consent form. If they again meet these criteria to the best of their knowledge, 
a second set of study screening procedures will be administered to evaluate whether or not they qualify for the study. 
All of the remaining screening and study procedures described hereinafter will be administered only if the participant has 
provided consent to participate (i.e., signed the consent form). 
 
Visit 1: Baseline testing and “Learning period“ of the vocabulary paired-associate learning task during tDCS session – 1 
hour: 
 
At the lab, the participants will be asked to complete some questionnaires such as a demographic questionnaire, a 
neuromodulation screening questionnaire, the Beck Depression Inventory, and the Beck Anxiety Inventory. 
 
After completing the questionnaires, the participant will be set up with the tDCS material that will start real or sham 
stimulation during the vocabulary paired-associate learning task. The two electrodes of the tDCS will be placed over the 
left and right C2 nerves dermatomes. For a real stimulation the electrical current will be initially increased in a ramp-like 
fashion over several seconds (5 seconds) until reaching 1.5mA and stimulation will be maintained for the duration of the 
task until it ramps down (5 seconds). For a sham stimulation, the electrical current will be increased in a ramp-like 
fashion over several seconds (5 seconds) until reaching 1.5mA to mimic the sensation present during the first 5 seconds 
of real stimulation and then stimulation will be stopped without the participant knowing. The total duration of the sham 
tDCS will be maintained for the duration of the task to be able to appropriately blind the procedure. To allocate 
participants in the different simulation groups in a fair way, participants will be assigned randomly to different groups. 
 
While the real or sham tDCS stimulation started, the “Learning period” of the computerized vocabulary paired-associate 
learning task will start which consists of 4 blocks (Karpicke and Roediger, 2008), each consisting of a study phase and a 
test phase. The 4 blocks are spread with a 30 second distractor task between the blocks. During the study phase 
participants will study 40 successively presented Swahili-English vocabulary pairs comprising common day-to-day words 
(e.g. Swahili: bustani, English: garden). The word pairs will be presented one below the other in the middle of the 
computer screen for 5 seconds. For each word pair the Swahili words will be correct transliterations in Roman alphabet 
of the English words. Participants will be instructed to read and remember the word pairs. The study phase will be 
followed by a test phase with a cued-recall test: Swahili cue words will be presented successively and participants will 
have to type-in the English translation during up to 8 seconds presentation time of the Swahili word and to press the 
return key at the end of the entry. The return key will stop the entry time-window and start the feedback time-window, 
where the computer program will display the correct English translation of the Swahili word for 1 second below the entry 
field. In cases when participants do not provide an entry, the computer program will stop the entry time-window after 8 
seconds automatically and display the feedback. The second version of the computerized vocabulary paired-associate 
learning task only differs in the testing phase of the task. Recalled word pairs will be dropped from further testing but 
studied in each subsequent study period in the second version. 
 
To allocate participants in the different group and test groups in a fair way, participants will be assigned randomly to 
one of four groups. One group will receive real tDCS paired with version 1 of the computerized vocabulary paired- 
associate learning task, the second group will get real tDCS paired with version 2 of the computerized vocabulary paired- 
associate learning task, the third group will receive sham tDCS paired with version 1 of the computerized vocabulary 
paired-associate learning task and the fourth group will get sham tDCS paired with version 2 of the computerized

vocabulary paired-associate learning task. 
 
After the tDCS procedure paired with the memory test, participants will need to fill out a tDCS questionnaire. 
 
Visit 2: i.e. 1 week after the first visit – Approximately 10 minutes: At the lab, the participants will start the test phase 
of the vocabulary paired-associate learning task. This is identical to the test phase from the learning period, i.e. all 
participants performed a cued-recall test with feedback, but did not restudy the word pairs.

A reasonable person would consider it to be important to know the risk of harm or discomfort when deciding whether to participate 
in the research project. 
 
Potential Risks 
Are there risks of physical harm or discomfort associated with the research? 
 Yes  
 No 
If yes, describe: - The most common side-effect of neurostimulation is temporally local redness of the skin direct 
under the electrode. This disappears within 1 hour. 
 
- Itching at the site of the electrode, passing within the hour 
 
- Slight feeling of dizziness when starting the stimulation occurs in a small number of 
participants. This takes only a few seconds and does not affect balance after stimulation 
 
- Very rarely, temporary skin damage may occur under the electrode. This gives a darkening of 
the skin, which normalizes after a weeks and heals. The size of such etch is a few millimeters. 
This is harmless, however, with the current that we will handle, this risk is minimal. 
 
On the safety of tDCS in healthy volunteers, in 2005 a well-conducted study published in the 
Journal of Neurology. There is a group of 103 people total tDCS stimulation given to 2 mA. 
Outside redness and itching they describe a transient slight improvement in language fluency 
(pronouncing words) or a transient slight delay in language fluency. The technique is seen as 
safe. 
 
Are there risks of psychological harm or discomfort associated with the research procedure? 
 Yes  
 No 
If yes, describe: 
 
Are there risks of social harm to the participants associated with the research? 
 Yes  
 No 
If yes, describe: 
 
Are there economic risks associated with the research? 
 Yes  
 No 
If yes, describe: 
 
What is your assessment of the overall risk classification of this research? 
 Minimal 
 Greater than Minimal Risk and the study presents the prospect of direct benefit to the participants 
 Greater than Minimal Risk and the study presents no prospect of direct benefit to the participants, but will likely yield 
generalizable knowledge about the study question. 
 
Minimizing Risks 
 
How will you minimize risks or discomfort? 
 Monitor the experiments by professional staff. 
 Provide opportunities for rest or breaks. 
 Withdrawal of participant based on specific criteria, explain: : All participants who are terminated from the study 
will have the reason for their termination documented.
