Meno's Paradox,the Slave‐Boy Interrogation,and the Unity of Platonic Recollection

Plato invokes the Theory of Recollection to explain both ordinary and philosophical learning. In a new reading of Meno's Paradox and the Slave‐Boy Interrogation, I explain why these two levels are linked in a single theory of learning. Since, for Plato, philosophical inquiry starts in ordinary discourse, the possibility of success in inquiry is tied to the character of the ordinary comprehension we bring to it. Through the claim that all learning is recollection, Plato traces the knowledge achievable through inquiry back to our pretheoretical comprehension, showing not just that knowledge is in us, but that it is inchoate in the grasp of a property—akin to a concept—that enables us to speak and think about it ordinarily. Plato acknowledges in the Meno that a second step of argument, and a second application of Recollection, is needed to explain how knowledge comes to be inchoate in our ordinary grasp of a property. Though this second argument is provided most fully in the Phaedo, the evidence of the Meno is sufficient to outline Recollection as a two‐stage theory of learning, beginning in ordinary speech and thought and extending, through philosophical reflection, to knowledge.     

A dual-process account of female facial attractiveness preferences: Sexual and nonsexual routes

The current study conceptualizes facial attractiveness as a dual-process judgment, combining sexual and aesthetic value. We hypothesized that holistic face processing is more integral to perceiving aesthetic preference and feature-based processing is more integral to sexual preference. In order to manipulate holistic versus feature-based processing, we used a variation of the composite face paradigm. Previous work indicates that slightly shifting the top from the bottom half of a face disrupts holistic processing and enhances feature-based processing. In the present study, while nonsexual judgments best explained facial attraction in whole-face images, a reversal occurred for split-face images such that sexual judgments best explained facial attraction, but only for mate-relevant faces (i.e., other-sex). These findings indicate that disrupting holistic processing can decouple sexual from nonsexual judgments of facial attraction, thereby establishing the presence of a dual-process.     

Re-conceptualizing the Factor Structure of the Brief Multidimensional Measure of Religiousness/Spirituality

Rationale This study attempted to differentiate statistically the spiritual and religious factors of the Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS), which was developed based on theoretical conceptualizations that have yet to be adequately empirically validated in a population with significant health disorders. Participants One hundred sixty-four individuals with heterogeneous medical conditions [i.e., brain injury, spinal cord injury (SCI), cancer, stroke, primary care conditions]. Methods Participants completed the BMMRS as part of a pilot study on spirituality, religion, and physical and mental health. Results A principal components factor analysis with varimax rotation and Kaiser normalization identified a six-factor solution (opposed to the expected 8-factor solution) accounting for 60% of the variance in scores, labeled as: (1) Positive Spiritual Experience; (2) Negative Spiritual Experience; (3) Forgiveness; (4) Religious Practices; (5) Positive Congregational Support; and (6) Negative Congregational Support. Conclusions The results suggest the BMMRS assesses distinct positive and negative aspects of religiousness and spirituality that may be best conceptualized in a psychoneuroimmunological context as measuring: (a) Spiritual Experiences (i.e., emotional experience of feeling connected with a higher power/the universe); (b) Religious Practices (i.e., prayer, rituals, service attendance); (c) Congregational Support; and (d) Forgiveness (i.e., a specific coping strategy that can be conceptualized as religious or non-religious in context).     

Neurophysiological evidence for categorical perception of color

The aim of this investigation was to examine the time course and the relative contributions of perceptual and post-perceptual processes to categorical perception (CP) of color. A visual oddball task was used with standard and deviant stimuli from same (within-category) or different (between-category) categories, with chromatic separations for within- and between-category stimuli equated in Munsell Hue. CP was found on a behavioral version of the task, with faster RTs and greater accuracy for between- compared to within-category stimuli. On a neurophysiological version of the task, event-related potentials (ERPs) showed earlier latencies for P1 and N1 components at posterior locations to between- relative to within-category deviants, providing novel evidence for early perceptual processes on color CP. Enhanced P2 and P3 waves were also found for between- compared to within-category stimuli, indicating a role for later post-perceptual processes.     

The Rev.: An IBM BASIC program for Bayesian test interpretation

The Rev. is a BASIC computer program for IBM-PC-compatible systems that provides Bayesian estimates of “true” scores from multiple scores measuring the same construct. Psychological reports often include test scores from earlier evaluations without objectively incorporating them into current findings. Using Thorndike’s formulas for objectively combining test scores while providing estimates with reduced standard errors, the Rev. is an interactive program that facilitates test interpretation by combining information from many test administrations. The user provides four easily obtainable pieces of information for each test administration. The output includes an estimated “true” score and the standard error of the estimate.     

Resilience in siblings of children with sickle cell disease

This pilot study was conducted to identify factors responsible for promoting resilience in siblings of children with sickle cell disease. Twenty siblings (10–17 years of age) of children (5–13 years) with sickle cell disease were selected from the Pediatric Clinic of Howard University Center for Sickle Cell Disease. The siblings responded to questionnaires, and the data obtained was analyzed by chi-square for association. The results indicated that age, birth order, and gender had no effect on resilience in the siblings. However, family size, number of parents in the home, sibling's knowledge of the illness, degree of morbidity of the illness, socioeconomic status of the family, and parents' attitudes and childrearing practices were all found to affect resilience. These findings provide additional insight into the psychosocial aspects of, and genetic counseling for sickle cell disease, as well as for other chronic genetic disorders.     

The multiple meanings of neutrality

Throughout the evolution of psychoanalysis, its theories and methods have been deeply influenced by ideas about psychoanalytic neutrality. However, considerable dissension has surrounded the concept of neutrality. This paper defines five distinct categories of neutrality the author considers relevant to all theoretical perspectives on psychoanalysis: behavioral, attitudinal, interpersonal, interactional, and essential.     

Are professors likely to report having “beliefs” about the intelligence and competence of students who stutter?

Some university students who stutter report that they avoid participating in class discussions and talking with professors because they believe that if their professors find out they stutter, the professors are likely to view the students as being less intelligent and/or competent than they otherwise would. The purpose of this study was to determine whether professors, as a group, are likely to report such beliefs. A random sample of 87 professors at Marquette University, Indiana University of Pennsylvania, and the State University of New York at Stonybrook rated “A Student Who Stutters” on each of 81 seven-point, bipolar semantic differential scales, including intelligent/unintelligent and competent/incompetent. Although there was considerable scatter in their ratings for the majority of the scales, 85 of the 87 rated the student at the center or “positive” end of the intelligent/unintelligent scale and 83 of the 87 did so on the competent/incompetent one. Assuming that the attitutes reported by the professors reflect their “real” ones, these data suggest that many—perhaps the majority—do not have negative attitudes about the intelligence and competence of their students who stutter.     

Developmental differences in the allocation of processing capacity

Recently psychologists have formulated a comprehensive view of attention involving allocation of processing capacity. Although developmental changes in processing capacity have been proposed as one source of age differences in certain cognitive skills, there has been little systematic investigation of this hypothesis. In the present study, second and sixth graders and adults (8, 12, and 20 years of age, respectively) performed a letter-matching task (primary task) concurrently with an auditory detection task (secondary task). Changes in reaction time in the secondary task as a function of manipulations of the primary task were used to estimate capacity allocation to the primary task. Primary task variables included stage of processing (alerting, encoding, rehearsing, responding) and matching condition (physical-identity vs name-identity matching). Age differences in secondary task performance were found to be related to stage of processing but not to matching condition. Earlier stages of the letter match task (alerting, encoding) required somewhat more capacity allocation in younger subjects. Later stages (rehearsing, responding) made substantially higher demands on capacity in children. Capacity allocation may be an important cognitive variable mediating developmental differences in basic information processing skills, and may underlie age trends found in performance of certain complex cognitive tasks.
