Accuracy, confidence, and calibration: how young children and adults assess credibility

Do children and adults use the same cues to judge whether someone is a reliable source of information? In 4 experiments, we investigated whether children (ages 5 and 6) and adults used information regarding accuracy, confidence, and calibration (i.e., how well an informant's confidence predicts the likelihood of being correct) to judge informants' credibility. We found that both children and adults used information about confidence and accuracy to judge credibility; however, only adults used information about informants' calibration. Adults discredited informants who exhibited poor calibration, but children did not. Requiring adult participants to complete a secondary task while evaluating informants' credibility impaired their ability to make use of calibration information. Thus, children and adults may differ in how they infer credibility because of the cognitive demands of using calibration.     

Repression versus sensitization in response to media violence as predictors of cognitive avoidance and vigilance

Repression and sensitization as situational modes of coping with anxiety were examined as predictors of trait measures of cognitive avoidance and vigilance. In this study, 303 undergraduates saw a violent film clip to elicit anxiety. Increases in skin conductance level (SCL) and state anxiety (STA) from baseline were measured to identify repressors (high SCL, low STA) and contrast them with sensitizers (low SCL, high STA) and genuinely low anxious individuals (low SCL, low STA). State anger was also recorded. Trait measures of vigilance and cognitive avoidance were collected 2 weeks earlier. Significant SCL × STA interactions indicated that repressors scored higher on cognitive avoidance and lower on vigilance compared to sensitizers and low anxious participants. Repressors were less likely than sensitizers to report gaze avoidance during the clip. The anger by SCL interaction was nonsignificant, suggesting that repressors and sensitizers differ specifically in the processing of anxiety rather than negative affect in general.     

Nurturing a Democratic Community in the Classroom

Thayer-Bacon tells her story in a conversational tone that traces her personal and professional roots as she describes various chapters of her life: first as a philosopher, how she became involved in education, and then how that involvement became a career as a philosopher of education, in a large teacher education program, and now at a research institution. She sketches her philosophical contributions, as a pragmatist, feminist, postmodernist, and cultural studies scholar, to philosophy, philosophy of education, and education.     

The non-epistemology of intelligent design: its implications for public policy

Intelligent design creationism (ID) is a religious belief requiring a supernatural creator’s interventions in the natural order. ID thus brings with it, as does supernatural theism by its nature, intractable epistemological difficulties. Despite these difficulties and despite ID’s defeat in Kitzmiller v. Dover Area School District (2005), ID creationists’ continuing efforts to promote the teaching of ID in public school science classrooms threaten both science education and the separation of church and state guaranteed by the U.S. Constitution. I examine the ID movement’s failure to provide either a methodology or a functional epistemology to support their supernaturalism, a deficiency that consequently leaves them without epistemic support for their creationist claims. My examination focuses primarily on ID supporter Francis Beckwith, whose published defenses of teaching ID, as well as his other relevant publications concerning education, law, and public policy, have been largely exempt from critical scrutiny. Beckwith’s work exhibits the epistemological deficiencies of the supernaturally grounded views of his ID associates and of supernaturalists in general. I preface my examination of Beckwith’s arguments with (1) philosopher of science Susan Haack’s clarification of the established naturalistic methodology and epistemology of science and (2) discussions of the views of Beckwith’s ID associates Phillip Johnson and William Dembski. Finally, I critique the religious exclusionism that Beckwith shares with his ID associates and the implications of his exclusionism for public policy.     

Dichotic listening and otoacoustic emissions: shared variance between cochlear function and dichotic listening performance in adults with normal hearing

The present study investigated a possible connection between speech processing and cochlear function. Twenty-two subjects with age range from 18 to 39, balanced for gender with normal hearing and without any known neurological condition, were tested with the dichotic listening (DL) test, in which listeners were asked to identify CV-syllables in a nonforced, and also attention-right, and attention-left condition. Transient evoked otoacoustic emissions (TEOAEs) were recorded for both ears, with and without the presentation of contralateral broadband noise. The main finding was a strong negative correlation between language laterality as measured with the dichotic listening task and of the TEOAE responses. The findings support a hypothesis of shared variance between central and peripheral auditory lateralities, and contribute to the attentional theory of auditory lateralization. The results have implications for the understanding of the cortico-fugal efferent control of cochlear activity.     

Introduction to special section of the Journal of Family Psychology, advances in mixed methods in family psychology: integrative and applied solutions for family science

Mixed methods in family psychology refer to the systematic integration of qualitative and quantitative techniques to represent family processes and settings. Over the past decade, significant advances have been made in study design, analytic strategies, and technological support (such as software) that allow for the integration of quantitative and qualitative methods and for making appropriate inferences from mixed methods. This special section of the Journal of Family Psychology illustrates how mixed methods may be used to advance knowledge in family science through identifying important cultural differences in family structure, beliefs, and practices, and revealing patterns of family relationships to generate new measurement paradigms and inform clinical practice. Guidance is offered to advance mixed methods research in family psychology through sound principles of peer review.
