Prior knowledge has been shown to be an important factor in causal judgments. However, inconsistent patterns have been reported regarding the interaction between prior knowledge and the processing of contingency information. In three studies, we examined the effect of the plausibility of the putative cause on causal judgments, when prior expectations about the rate at which the cause is accompanied by the effect in question are explicitly controlled for. Results clearly show that plausibility has a clear effect that is independent of contingency information and type of task (passive or active). We also examined the role of strategy use as an individual difference in causal judgments. Specifically, the dual-strategy model suggests that people can either use a Statistical or a Counterexample strategy to process information. Across all three studies, results showed that Strategy use has a clear effect on causal judgments that is independent of both plausibility and contingency.
Prior research has showed the importance of providing integrated support services to prevent and reduce youth not in education, employment, or training (NEET) related challenges. There is limited evidence on NEET youth's perspectives and preferences for employment, education, and training services. The objective of this study was to identify employment, education and training service preferences of NEET youth. We acknowledge the deficit-based lens associated with the term NEET and use 'upcoming youth' to refer to this population group. Canadian youth (14-29 years) who reported Upcoming status or at-risk of Upcoming status were recruited to the study. We used a discrete choice experiment (DCE) survey, which included ten attributes with three levels each indicating service characteristics. Sawtooth software was used to design and administer the DCE. Participants also provided demographic information and completed the Global Appraisal of Individual Needs-Short Screener. We analyzed the data using hierarchical Bayesian methods to determine service attribute importance and latent class analyses to identify groups of participants with similar service preferences. A total of n=503 youth participated in the study. 51% of participants were 24-29 years of age; 18.7% identified as having Upcoming status; 41.1% were from rural areas; and 36.0% of youth stated that they met basic needs with a little left. Participants strongly preferred services that promoted life skills, mentorship, basic income, and securing a work or educational placement. Three latent classes were identified and included: (i) job and educational services (38.9%), or services that include career counseling and securing a work or educational placement; (ii) mental health and wellness services (34.9%), or services that offer support for mental health and wellness in the workplace and free mental health and substance use services; and (iii) holistic skills building services (26.1%), or services that endorsed skills for school and job success, and life skills. This study identified employment, education, and training service preferences among Upcoming youth. The findings indicate a need to create a service model that supports holistic skills building, mental health and wellness, and long-term school and job opportunities.
Prior research into bystander responses to hate speech has utilized variable-centered analyses - such approaches risk simplifying the complex nature of bystander behaviors. Hence, the present study used a person-centered analysis to investigate latent hate speech bystander profiles. In addition, individual and classroom-level correlates associated with the various profiles were studied. The sample included 3225 students in grades 7-9 (51.7% self-identified as female; 37.2% with immigrant background) from 215 classrooms in Germany and Switzerland. The latent profile analysis revealed that four distinct profiles could be distinguished: Passive Bystanders (34.2%), Defenders (47.3%), Revengers (9.8%), and Contributors (8.6%). Multilevel logistic regression models showed common and distinct correlates. For example, students who believed that certain social groups are superior were more likely to be Revengers and Contributors than Passive Bystanders, students who felt more connected with teachers were more likely to be Defenders, and students who were more open to diversity were less likely to be Contributors than Passive Bystanders. Students were less likely Defenders and more likely Revengers and Contributors than Passive Bystanders in classrooms with high rates of hate speech perpetration. Further, in classrooms with high hate speech intervention, students were more likely to be Defenders and less likely to be Contributors than Passive Bystanders. In classrooms with stronger cohesion, students were more likely to be Defenders and less likely to be Contributors than Passive Bystanders. In conclusion, the findings add to our understanding of bystander profiles concerning racist hate speech and the relevance of individual and classroom-level factors in explaining various profiles of bystander behavior.
Prior to the establishment and promotion of ADHD as a psychiatric disorder, the labels "minimal brain dysfunction" (MBD), "hyperactivity" (HA), and "learning disability" (LD) were diagnostic terms for children with hard-to-manage behaviors. At the time, these labels and the treatment interventions, especially the heavy reliance on stimulant medications, were subject to criticism. Nearly half a century later, these criticisms apply equally to ADHD, suggesting a disturbing lack of progress in this area of child psychiatry. Therefore, the aim of this article is to examine the scientific integrity of ADHD, to establish why this is the case. I use a philosophy of science framework to track the initial thinking, the plausibility, and the acceptance of ADHD. I establish that ADHD, along with the evolving biomedical model for psychiatry, was accepted in the third edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual (DSM-III) as the result of bias and compromise between theorists' of different persuasions. Although initial ideas are expected to be subjective, they also need to demonstrate plausibility prior to empirical investigation. Research from the disciplines of biological psychiatry and cognitive psychology influenced the creation of ADHD, so I critically examine specific ideas that underpinned these disciplines at that time. I find these to be implausible and not congruent with current scientific knowledge, this extends to more recent theory. I conclude there is little good reason to consider DSM-III's concept of ADHD as empirically confirmed, nor do I find good reason to expect such confirmation will be forthcoming.
Prioritizing diagnostic hypotheses can be difficult for novice medical students given their limited clinical exposure. Simulated clinical reasoning (CR) clinics allow students to practice focused histories with a simulated patient (SP). The delivery of clinical data by SPs can influence hypothesis generation. This pilot study seeks to test whether the transmission of key elements through SP acting influences CR prioritization among medical students. The diagnostic hypotheses of two cohorts of students of the same academic level were compared following a virtual interview with an SP. The SPs in the experimental group were given a targeted script and briefing on key elements while the SPs in the control group were given a traditional script and briefing. The difference between the distributions of frequencies of the hypotheses of the two groups was determined using the chi-square calculation. The students in the experimental group prioritized expert-validated hypotheses more than those in the control group. The control group showed greater variability in their diagnostic choices. Targeting the delivery of key elements by SPs could be a way to help novice medical students prioritize their diagnostic hypotheses. Simulated CR clinics therefore become a space for learning about CR in the absence of clinical exposure. The risk of inducing premature closure of clinical reasoning needs further research.
Prisoners' oral health and general health are closely connected and generally poorer than that of the wider population. Moreover, knowledge of prisoners' health literacy is scarce. This study aimed to explore prisoners' perceived oral and general health and how they accessed, understood and assessed health information to gain insight into their health literacy. Twelve prisoners in a high-security prison and a halfway house participated in individual semi-structured interviews. Data was analysed through thematic analysis, which identified five themes: inconsistent self-reporting of general and oral health; autonomous health behaviour through utilizing personal resources; preference for personalized adapted health information; psychological and physical proximity; and barriers. The prisoners perceived their oral and general health as good despite several health problems. They expressed scepticism towards health information from public authorities and made their own health-related choices based on previous experiences, their own 'common sense' and the experiences of people they trusted. Health information was considered useful when adjusted to their needs. Obtaining health-related information through physical encounters was considered more accessible than through online platforms. Adapting the communication to prisoners' expressed needs and their health literacy can enhance the accessibility to improve their oral and general health. In-person encounters would be preferable.
Probabilistic planning attempts to incorporate stochastic models directly into the planning process, which is the problem of synthesizing a sequence of actions that achieves some objective for a putative agent. Probabilistic programming has rapidly emerged as a key paradigm to integrate probabilistic concepts with programming languages, which allows one to specify complex probabilistic models using programming primitives like recursion and loops. Probabilistic logic programming aims to further ease the specification of structured probability distributions using first-order logical artefacts. In this article, we briefly discuss the modelling of probabilistic planning through the lens of probabilistic (logic) programming. Although many flavours for such an integration are possible, we focus on two representative examples. The first is an extension to the popular probabilistic logic programming language PROBLOG, which permits the decoration of probabilities on Horn clauses-that is, prolog programs. The second is an extension to the popular agent programming language GOLOG, which permits the logical specification of dynamical systems via actions, effects and observations. The probabilistic extensions thereof emphasize different strengths of probabilistic programming that are particularly useful for non-trivial modelling issues raised in probabilistic planning. Among other things, one can instantiate planning problems with growing and shrinking state spaces, discrete and continuous probability distributions, and non-unique prior distributions in a first-order setting.
Problem-based learning (PBL) is a student-centered approach to teaching that has been applied in medical and nursing education. The effectiveness of PBL in promoting critical thinking in nursing students has been studied extensively with mixed results. The meta-analysis aimed to investigate the impact of PBL interventions on critical thinking skills of nursing students. PubMed, Embase, Cochrane, and CINAHL databases were electronically searched. Methodological quality was examined using the Newcastle-Ottawa Scale and version 2 of the Cochrane risk-of-bias tool. Data were analyzed with 95% confidence intervals based on random-effect models. Nineteen studies involving 1996 nursing students were included in the analysis. The results of the analysis demonstrated greater improvement in critical thinking skills compared with the control group (overall critical thinking scores: standardized mean difference [SMD] = 0.47, 95% CI = 0.33-0.61, P < .01). The meta-analysis indicates that PBL can help nursing students to improve their critical thinking.
Problem-Based Learning (PBL) relies on self-directed learning in small groups in the presence of a tutor. While the effectiveness of PBL is often attributed to the dynamics of group function, change in group function over time and factors influencing group function development are less understood. This study aims to explore the development of PBL group function over time to better understand the factors that give rise to high-functioning groups. We examined time-function graphs of group function and conducted semi-structured focus group discussions in 2023 with medical students enrolled in a PBL curriculum. Students reflected on their experiences in four different PBL groups, creating time-function graphs to characterize development of group function over 8-12-week periods. We analyzed graphs and transcripts in a staged approach using qualitative description and direct content analysis, sensitized by two frameworks: Tuckman's Stages of Group Development and the Dimensions of PBL Group Function. Three archetypes of PBL group function development were identified: Slow Shifters, Fast Flippers, and Coasters. (1) Slow Shifters were characterized by a complex and extended pattern of growth consistent with Tuckman's model, typically occurring amongst inexperienced groups, or groups faced with a novel task. (2) Fast Flippers were characterized by abrupt state changes in group function arising from internal or external disruptions. (3) Coasters were characterized by plateaus, where maintenance of group function was a frequently cited challenge. Abrupt changes and plateaus occurred more among mature groups and groups with significant PBL experience. PBL group function varies over time in 3 different patterns. Classic Tuckman's stages are apparent among inexperienced groups, or groups facing novel tasks, whereas experienced groups often face abrupt change or plateaus. PBL educators and students should consider the need for novelty and disruption in more experienced groups to incite growth.
Problem-based learning (PBL) was introduced to address passive teaching limitations. However, it is not fully characterised as a teaching modality in pharmacology. The present study investigated the factors affecting pharmacology learning in an integrated PBL-based curriculum in diverse learners. Year 1 undergraduate medical students from two cohorts at St. George's University of London and University of Nicosia, participated. Statistical analysis of pharmacology knowledge scores, at the beginning (pre-test) and end of the academic year (post-test), investigated readiness to benefit from PBL based on diverse student characteristics (educational background, age, gender, country of origin, ethnicity, native language, PBL experience). Focus groups/interviews and a survey investigated aspects of integrated PBL impacting learning in depth. Pre- and post-test scores were positively correlated. Students with biomedical sciences degrees performed better at the pharmacology pre- and post-tests, while post-graduate degree holders performed better only at the pre-test. Effect size was of moderate magnitude. However, progress in learning (post-test performance after controlling for pre-test scores) was unaffected. Qualitative analysis revealed three major themes: 1) PBL as a learning environment; 2) PBL as a learning environment in pharmacology; and 3) PBL as a learning environment and confidence in prescribing. Under theme one, skill development, knowledge acquisition through collaboration and self-directed learning, group dynamics and preferred teaching methods were discussed. Under theme two, contextual learning, depth of knowledge and material correctness were raised. Under theme 3, students expressed variability in prescribing confidence. They perceived that learning could be improved by better integration, further references earlier on, more lectures and PBL facilitators with greater content expertise. The survey findings were consistent with those from focus groups/interviews. Pharmacology learning in a PBL-based curriculum is facilitated by constructive, collaborative and contextual learning. While baseline pharmacology knowledge may be advantageous, the other aforementioned characteristics studied may not affect readiness to benefit from PBL. However, further instructional scaffolding is needed, for example through further resources, lectures and self-assessment. The results from our study can inform evidence-based curriculum reform to support student learning further. Addressing learning needs could ultimately contribute to reducing medication errors through effective training of future prescribers.
Problem-solving and reasoning involve mental exploration and navigation in sparse relational spaces. A physical analogue is spatial navigation in structured environments such as a network of burrows. Recent experiments with mice navigating a labyrinth show a sharp discontinuity during learning, corresponding to a distinct moment of "sudden insight" when mice figure out long, direct paths to the goal. This discontinuity is seemingly at odds with reinforcement learning (RL), which involves a gradual build-up of a value signal during learning. Here, we show that biologically plausible RL rules combined with persistent exploration generically exhibit discontinuous learning. In tree-like structured environments, positive feedback from learning on behavior generates a "reinforcement wave" with a steep profile. The discontinuity occurs when the wave reaches the starting point. By examining the nonlinear dynamics of reinforcement propagation, we establish a quantitative relationship between the learning rule, the agent's exploration biases, and learning speed. Predictions explain existing data and motivate specific experiments to isolate the phenomenon. Additionally, we characterize the exact learning dynamics of various RL rules for a complex sequential task.
Problem-solving skills are the most applicable cognitive tool in mathematics, and improving the problem-solving skills of students is a primary aim of education. However, teachers need to know the best period of development and the differences among students to determine the best teaching and learning methods. This study aims to investigate the development and differences in mathematical problem-solving skills of students based on their grades, gender, and school locations. A scenario-based mathematical essay test was administered to 1067 students in grades 7-9 from schools in east Java, Indonesia, and their scores were converted into a logit scale for statistical analysis. The results of a one-way analysis of variance and an independent sample t-test showed that the students had an average level of mathematical problem-solving skills. The number of students who failed increased with the problem-solving phase. The students showed development of problem-solving skills from grade 7 to grade 8 but not in grade 9. A similar pattern of development was observed in the subsample of urban students, both male and female. The demographic background had a significant effect, as students from urban schools outperformed students from rural schools, and female students outperformed male students. The development of problem-solving skills in each phase as well as the effects of the demographic background of the participants were thoroughly examined. Further studies are needed with participants of more varied backgrounds.
Problem: A significant proportion of learning during residency takes place through informal channels. Spontaneous collaboration among medical learners significantly contributes to this informal learning and is increasingly recognized as a component of the hidden curriculum in medical education. Yet historically, a disproportionate emphasis in medical education has been placed on didactic, structured, and faculty-initiated methods, leaving an important force in medical education understudied and underutilized. We hypothesize that there is significant educational potential in studying and deploying targeted tools to facilitate collaboration among medical learners. Intervention: At our institution, neurology residents implemented the "Daily Fact Pile" (DFP), a resident-led, email-based collaboration that served as a platform to share clinical pearls in an informal, digital way. Participation was voluntary and participants were encouraged to share facts that were new to them and thought to be clinically relevant. Motivated by the positive collective experience, we conducted a retrospective examination of this phenomenon. In this context, we developed the concept of "mutual microlearning" to characterize this efficient, multidirectional exchange of information. Context: Thirty-six residents in a single neurology residency program utilized the DFP at a large university hospital in the USA between 2018 and 2019. After 21 months of spontaneous and voluntary participation, we assessed the feasibility of the DFP, its impact on the education and morale of neurology residents, and compared its mutual microlearning approach to traditional lectures. This was done through a survey of the DFP participants with a response rate of 80.7%, and analysis of the statistics of participation and interaction with the DFP. Impact: Most participants felt that the DFP was beneficial to their education and thought they often or always learned something new from reading the DFP. The impact of the DFP extended beyond education by improving interest in neurology, morale, and sense of teamwork. The DFP was feasible during neurology residency and participation was high, though participants were more likely to read facts than share them. Lessons learned: Mutual microlearning represents an opportunity to augment residents' education, and well-designed mutual microlearning tools hold promise for complementing traditional teaching methods. We learned that efficiency, ease of use, and a supportive, non-judgmental environment are all essential to the success of such tools. Future research should delve deeper into the underlying mechanisms of mutual microlearning to establish its position within the theoretical frameworks of medical education.
