Maximizing Efficiency of Enrollment for School‐Based Educational Research1

In this observational study, influences on research enrollment were examined in the context of an educational research study. Recruitment materials were sent to parents of kinder‐gartners in one of 23 classes across 7 public schools, as an invitation to enroll in a longitudinal study. For the 7 classes from 2 of the schools, the school principal prepared a cover letter as an introduction to the educational study. Inclusion of this cover letter was associated with a significantly swifter pace of recruitment and, to a lesser degree, with an increase in the number of children enrolled. However, when potential confounding variables were controlled, no significant increase in final enrollment count was associated with including the cover letter. Thus, inclusion of a cover letter from the school principal did not appear to dramatically increase the number of parents who elected to enroll their child in the educational study, and it did significantly decrease (by 6 weeks) the number of weeks required to achieve final enrollment counts.     

Is unconscious identity priming lexical or sublexical?

We examined unconscious priming in a stem-completion task with both identity and form-related primes. Participants were given exclusion instructions to avoid completing a stem (e.g., ca---) with a briefly flashed masked word (e.g., candy). In Experiment 1, priming of around 7% occurred for both identity (e.g., candy) and form-based (e.g., windy) primes at a 33 ms exposure duration. When examining only trials in which the participants failed to identify the prime, this effect increased to 12% for identity primes, but remained the same for form-based primes. In Experiment 2, priming without prime identification was 9% for identity primes, 4% for homophone primes, and 3% for orthographic control primes. Although identity priming was greater than form priming in both experiments, regression analyses revealed that orthographic and phonological overlap alone between the flashed primes and targets could completely account for unconscious identity priming. Hence, we conclude that masked words may only activate their sublexical orthographic and phonological representations and not their lexical representations.     

Ethnic differences in clinical presentation of depression in adult women

This study examined ethnic differences in self-report and interviewer-rated depressive symptoms and estimated the contributions of sociodemographic and psychosocial factors in predicting severity of depression. One hundred twenty-five clinically depressed African American (n = 46), Caucasian (n = 36), and Latina (n = 43) women were recruited. After controlling for differences in socioeconomic status, African American women reported more symptoms of distress and Latinas were rated as significantly more depressed than the other groups. However, these ethnic differences were not moderated by either education or employment. Finally, hierarchical regression analysis indicated that severity of depression was predicted by low education, being single, being Latina, high perceived stress, and feelings of hopelessness. Additional research is needed to validate these results and to investigate their clinical significance.     

Selective hippocampal lesions disrupt a novel cue effect but fail to eliminate blocking in rabbit eyeblink conditioning

The classical conditioning task of blocking involves the adding of a novel but redundant stimulus to a previously trained stimulus. Both blocking and novelty detection are thought to involve the hippocampus. Previously, Solomon (1977) found that nonselective aspiration lesions of the hippocampal region eliminated blocking in rabbit eyeblink conditioning. We tested the effects of selective ibotenic acid lesions of the hippocampus on blocking, as well as on novelty detection, when training is switched from a tone conditioned stimulus (CS) to a compound tone-light CS in eyeblink conditioning. Selective hippocampal lesions did not eliminate blocking but did lead to a facilitation of conditioned response (CR) acquisition to the tone and to the light, but not to the tone-light compound. Selective hippocampal lesions disrupted a CR decrement observed in sham surgical controls when transferred from tone training to tone-light training. It appears that although selective hippocampal lesions do not eliminate blocking in eyeblink conditioning, they do disrupt novelty detection and may facilitate learning to a previously blocked cue.     

Relation of useful field of view and other screening tests to on-road driving performance

The purpose of this study was to examine the value of a clinical driving assessment battery in predicting performance on an on-road driving test. 43 participants referred to the Bryn Mawr Rehab Adapted Driving Program for evaluation of driving ability underwent an evaluation consisting of a predriver screening and an on road driving test. The predriver screening included a vision screening, a reaction rime task, a split-attention task, the Hooper Visual Organization Test, verbal and symbolic sign recognition, and assessment of Useful Field of View. Logistic regression analyses were applied to identify which predriver screening variables could be used to predict outcome on the on road driving test (pass/fail); UFOV was that best single predictor. The addition of screening tests beyond UFOV alone did not increase predictive validity. These findings suggest that UFOV may serve as an indicator of the need for further driving assessment.     

Family or friends: who plays a greater supportive role for Latino college students?

This study compared the relative contribution of perceived family and friend support to psychological well-being and distress and examined whether family or friend support moderated the effects of stress on psychological adjustment in 338 Latino (228 Mexican American, 110 Central American) college students from a predominantly Latino university. Two multiple regressions, controlling for gender, socioeconomic level, acculturation level, and stresses (generic college, acculturative, and minority status), showed that friend support made a slightly greater contribution to well-being than family support, and friend support and not family support protected against psychological distress. Neither family nor friend support moderated the effects of stress on psychological adjustment. Further examination of these variables that assess common-specific stresses within a culture-specific theoretical framework is recommended.     

The transcendent function in Spitteler’s Prometheus and Epimetheus

In August 2020, John Beebe and Steve Myers met via Zoom to discuss their differing interpretations of psychological typology and the different sources within Jung’s writings that influenced their books: Integrity in Depth: Energies and Patterns in Psychological Type (Beebe), and Myers-Briggs Typology vs Jungian Individuation (Myers). The discussion centred on Spitteler’s epic poem Prometheus und Epimetheus, which forms the basis of chapter V of Psychological Types. This is both the largest chapter and one of two chapters that Jung highlighted in the Argentine foreword as containing the essence of the book. Jung’s book is primarily about the transformation of personality rather than the categorization of people. Although it contains a critical psychology that deconstructs the nature of consciousness, that is only one half of the book and a stepping-stone to the other half, which is the reconciliation of opposites with particular emphasis on the relation of consciousness and the unconscious. Jung assumed that readers were already familiar with Prometheus und Epimetheus, an understanding of which sheds light on the nature of the transformation that Jung described – the development of a new attitude towards attitude itself.     

Investigation of the Use of a Family Health History Application in Genetic Counseling

The paper-based pedigree is the current standard for family health history (FHH) documentation in genetic counseling. Several tools for electronic capture of family health data have been developed to improve re-use and accessibility, data quality and standardization, ease of updating, and integration with electronic medical records. One such tool, the tablet-based Proband application, provides a flexible approach to data capture in dynamic and diverse clinical settings. This study compared Proband FHH collection to paper-based methods and investigated the usability of Proband in a clinical setting. After one use by 23 genetic counselors and students, Proband had 91% accuracy with a FHH audio scenario, which was significantly less (p?<?0.001) than paper’s 96% accuracy. These differences were attributed to incorrect or missing ages of grandparents (p?<?0.001) and great-aunts/uncles (p?=?0.012) and missing documentation of consanguinity (p?<?0.001). Possible explanations for these differences include greater experience with paper FHH documentation and pre-populated prompts for consanguinity on the paper template used. Proband’s perceived usability increased with use, with individual System Usability Scores increasing between first and last use (p?=?0.033). We conclude that tools for dynamic, provider-driven FHH documentation such as Proband show promise for improving risk assessment accuracy and quality patient care.     

Creativity in Medical Education: The Value of Having Medical Students Make Stuff

What is the value of having medical students engage in creative production as part of their learning? Creating something new requires medical students to take risks and even to fail--something they tend to be neither accustomed to nor comfortable with doing. “Making stuff” can help students prepare for such failures in a controlled environment that doesn’t threaten their professional identities. Furthermore, doing so can facilitate students becoming resilient and creative problem-solvers who strive to find new ways to address vexing questions. Though creating something new can be fun, this is not the main outcome of interest. Rather, the principle reason we recommend devoting precious curricular time to creative endeavors is because it helps medical students become better doctors.
