Perceptions of Credibility for a Memory Report of a Single Versus Repeated Event

Summary: When a person experiences an event that has multiple similar instances (i.e., a repeated event), memories for details that change across instances are challenging to recall. We expected that third parties would perceive memory reports of instances of repeated events as less credible than they would unique (i.e., single) events. Undergraduates participated in a single or repeated event, during which critical details were presented. Participants were asked to recall the session 2 days later, and memory reports were video recorded. New participants then viewed one video and evaluated the credibility of the speaker's memory report. Overall, repeated‐event reports were seen as less credible than were single‐event reports, despite the reports being equally accurate. Although credibility research in the context of repeated events has focused exclusively on child populations, a range of applications exists for adults (e.g., criminal and industrial eyewitnesses, and asylum seekers); we discussed our findings in these areas.Copyright © 2017 John Wiley & Sons, Ltd.     

FURNISHING THE SKILL WHICH CAN SAVE THE CHILD: DIPHTHERIA,GERM THEORY,AND THEODICY

Amid the diverse ways men and women have viewed the relationship between science and religion, explicit arguments that “Science is God's Provision” remain unexamined by historians. Such arguments are examined here as they relate to the problem of theodicy, by looking at a particular case study that inspired comments on the relationship between medicine and faith, namely, the discovery of the diphtheria antitoxin. This story highlights, first, the flexibility of the tradition of natural theology, and second, the important role the problem of theodicy has played in the history of the relationship between science and religion.     

Should Genetic Testing be Offered for Children? The Perspectives of Adolescents and Emerging Adults in Families with Li-Fraumeni Syndrome

Whether children should be offered genetic testing for cancer risk is much debated but young voices are rarely heard in these conversations. The current study explored perspectives of genetic testing held by adolescents and emerging adults in families with Li Fraumeni syndrome (LFS). Twelve 12- to 25-year-olds in families with LFS completed qualitative interviews for this study. All believed that testing should be offered for children but many qualified this statement saying parental approval would be needed and testing should be optional. Genetic testing was seen as way to learn of risk status, allow for disease prevention efforts, and reduce uncertainty and anxiety. Perceived disadvantages included negative emotions associated with the testing result. Participants generally felt that children should be involved in the testing decision, but that parents could unilaterally decide to have a child tested in certain circumstances (e.g., young age, high risk). All who were aware of having been tested and of their test result (n = 7; 4 positive) said testing had no negative impact on their outlook and they agreed with the decision to undergo testing. Implications of these findings for clinical practice and future research are discussed.     

Gender differences on the mental rotations test: a factor analysis

The purpose of the present study was to examine possible gender differences in strategy when completing the mental rotations test. Two experiments examined gender differences and the factor structure on outcomes that can be obtained on this test. Experiment 1 involved large groups testing and Experiment 2 used small groups. Factor analytic results in both experiments generally supported the notion that items with one wrong and one blank response or one correct and one blank reflect reluctance to guess, whereas one correct and one wrong or two wrong answers reflect propensity to guess. Even though the factor structure was the same in males and females, the data provided mitigated support for the hypothesis that males have a higher propensity to guess and females show a greater reluctance to guess. Findings are discussed in terms of their implications for the interpretation of gender differences on the MRT.     

A window on the normal development of sensitivity to global form in Glass patterns

We studied the development of sensitivity to global form in 6-year-olds, 9-year-olds, and adults (n = 24 in each group) using Glass patterns with varying ratios of paired signal dots to noise dots. The developmental pattern was similar whether the global structure within the Glass patterns was concentric or parallel. Thresholds were equally immature for both types of pattern at 6 years of age (about twice the adult value) but were adult-like at 9 years of age. Together, the results indicate that the cortical structures involved in the processing of global form achieve functional maturity between 6 and 9 years of age. During middle childhood, the mechanisms mediating sensitivity to concentric structure develop at the same rate as those mediating sensitivity to parallel structure.     

Impairment in holistic face processing following early visual deprivation

Unlike most objects, faces are processed holistically: They are processed as a whole rather than as a collection of independent features. We examined the role of early visual experience in the development of this type of processing of faces by using the composite-face task, a measure of holistic processing, to test patients deprived of visual experience during infancy. Visually normal control subjects showed the expected composite-face effect: They had difficulty perceiving that the top halves of two faces were the same when the top halves were aligned with different bottom halves. Performance improved when holistic processing was disrupted by misaligning the top and bottom halves. Deprived patients, in contrast, showed no evidence of holistic processing, and in fact performed significantly better than control subjects when top and bottom halves were aligned. These findings suggest that early visual experience is necessary to set up or maintain the neural substrate that leads to holistic processing of faces.     

Assessment of mindfulness by self-report: the Kentucky inventory of mindfulness skills

A self-report inventory for the assessment of mindfulness skills was developed, and its psychometric characteristics and relationships with other constructs were examined. Participants included three samples of undergraduate students and a sample of outpatients with borderline personality disorder Based on discussions of mindfulness in the current literature, four mindfulness skills were specified: observing, describing, acting with awareness, and accepting without judgment. Scales designed to measure each skill were developed and evaluated. Results showed good internal consistency and test-retest reliability and a clear factor structure. Most expected relationships with other constructs were significant. Findings suggest that mindfulness skills are differentially related to aspects of personality and mental health, including neuroticism, psychological symptoms, emotional intelligence, alexithymia, experiential avoidance, dissociation, and absorption.     

Brain potentials implicate temporal lobe abnormalities in criminal psychopaths

Psychopathy is associated with abnormalities in attention and orienting. However, few studies have examined the neural systems underlying these processes. To address this issue, the authors recorded event-related potentials (ERPs) while 80 incarcerated men, classified as psychopathic or nonpsychopathic via the Hare Psychopathy Checklist--Revised (R. D. Hare, 1991, 2003), completed an auditory oddball task. Consistent with hypotheses, processing of targets elicited larger frontocentral negativities (N550) in psychopaths than in nonpsychopaths. Psychopaths also showed an enlarged N2 and reduced P3 during target detection. Similar ERP modulations have been reported in patients with amygdala and temporal lobe damage. The data are interpreted as supporting the hypothesis that psychopathy may be related to dysfunction of the paralimbic system--a system that includes parts of the temporal and frontal lobes.     

A preliminary evaluation of two behavioral skills training procedures for teaching abduction-prevention skills to schoolchildren

Although child abduction is a low-rate event, it presents a serious threat to the safety of children. The victims of child abduction face the threat of physical and emotional injury, sexual abuse, and death. Previous research has shown that behavioral skills training (BST) is effective in teaching children abduction-prevention skills, although not all children learn the skills. This study compared BST only to BST with an added in situ training component to teach abduction-prevention skills in a small-group format to schoolchildren. Results showed that both programs were effective in teaching abduction-prevention skills. In addition, the scores for the group that received in situ training were significantly higher than scores for the group that received BST alone at the 3-month follow-up assessment.     

Developmental changes in the processing of hierarchical shapes continue into adolescence

The present study was designed to trace the normal development of local and global processing of hierarchical visual forms. We presented pairs of hierarchical shapes to children and adults and asked them to indicate whether the two shapes were the same or different at either the global or the local level. In Experiments 1 (6-year-olds, 10-year-olds, adults) and 2 (10-year-olds, 14-year-olds, adults), we presented stimuli centrally. All age groups responded faster on global trials than local trials (global precedence effect), but the bias was stronger in children and diminished to the adult level between 10 and 14 years of age. In Experiment 3 (10-year-olds, 14-year-olds, adults), we presented stimuli in the left or right visual field so that they were transmitted first to the contralateral hemisphere. All age groups responded faster on local trials when stimuli were presented in the right visual field (left hemisphere); reaction times on global trials were independent of visual field. The results of Experiment 3 suggest that by 10 years of age the hemispheres have adult-like specialization for the processing of hierarchical shapes, at least when attention is directed to the global versus local level. Nevertheless, their greater bias in Experiments 1 and 2 suggests that 10-year-olds are less able than adults to modulate attention to the output from local versus global channels-perhaps because they are less able to ignore distractors and perhaps because the cerebral hemispheres are less able to engage in parallel processing.
