Personality Disorders and Spinal Cord Injury: A Pilot Study

A substantial body of research has found that spinal cord injury (SCI) patients have relatively high degrees of energy, impulsivity, and risk-taking (W. Fordyce, 1964; G. P. Taylor, 1970; B. Woodbury, 1978). The present study endeavors to extend our knowledge to the personality disorder (PD) domain. Forty SCI participants and 40 matched controls were given a semistructured diagnostic interview and a self-report personality disorder instrument. Findings indicated that 27.5% of SCI patients, and a similar number of controls, have PDs. Unexpectedly, impulsive/externalizing disorders (histrionic, narcissistic, antisocial, and borderline) were not unusually high in SCI patients, and were not higher than controls. Avoidant and depressive disorders were unexpectedly high.     

The Structure and Dynamics of Worry: Theory, Measurement, and Cross-National Replications

This article presents a comprehensive conceptualization of the structure of worry and the relation of worry to mental health and well-being. It is assumed that worries have two facets, namely, the object of a worry (e.g., self, close others, society, the world) and the domain of a worry (the field of life with which it is concerned). The object of a worry is presumed to be more important than its domain in determining the impact of worries on mental health. Only worries concerned with self and close others (micro worries) are expected to be related to poor mental health, whereas worries about society or the entire world (macro worries) are expected to be positively related to mental health. An instrument is introduced to study worries in accordance with the proposed structure. Its validity is tested by two confirmatory techniques (similarity structure analysis and confirmatory factor analysis) in samples from Israel, West Germany, and (the former) East Germany. Worry scores are also related to five mental health indicators. Results show that across samples micro and macro worries can validly be distinguished. Micro worries are strongly related to poor mental health, whereas macro worries are unrelated to mental health or relate marginally to positive well-being.     

Prehension movements and perceived object depth structure

This study asked the question, “Will the motor pattern to a perceived two-dimensional (2-D) object differ from that same object when it is perceived as three dimensional (3-D)?” Subjects were required to reach and grasp an apple that could appear to be 2-D or 3-D. Two experimental sessions were conducted. In Condition A, the apple was initially perceived to be 2-D, but, for 20% of trials, it suddenly shifted to a 3-D apple at movement onset. In Condition B, the apple was initially perceived to be 3-D, but, for 20% of trials, it suddenly shifted to a 2-D silhouette of the same apple. For control trials, subjects grasped the perceived 2-D apple as if it were a disc (82%), and they grasped the 3-D apple, as they would a normal apple, with a whole-hand grasp (86%). For Condition A perturbed trials, there was a rapid change from a 2-D precision grip to a 3-D whole-hand prehension, whereas the converse was true for the opposite perturbation. Peak acceleration was anticipated for Condition A perturbed trials but not for Condition B perturbed trials. These results indicate that the motor patterns we use in interacting with an object are strongly influenced by the way we perceive the object in real time, and that object affordances, such as dimension, can override the influence exerted by existing representations.     

Cognitive costs of encoding novel natural activities: Can “learning by doing” be distracting and deceptive?

Findings from action memory research suggest that the enactment of simple actions and naturalistic activities results in similar memory performance to that from their observation. However, little is known about potential differences between the conditions during the encoding of the to-be-studied actions and activities. We analysed the cognitive costs of encoding two novel naturalistic activities studied via enactment or via observation in four experiments. In addition to memory performance, we measured objective cognitive costs with a secondary task and subjective cognitive costs with repeated ratings of mental effort and estimates of general activity difficulty. Memory performance was comparable across study conditions throughout all experiments. The enactment of activities repeatedly resulted in slower reaction times in the secondary task than did observation, suggesting higher objective costs. In contrast, subjective costs were rated lower after enactment than after observation. Findings from a pantomimic enactment condition suggested that the low ratings of subjective costs after enactment represent a misinterpretation of task demands. Our findings imply that the widespread belief about “learning by doing” as an easy way of learning does not stem from an actual advantage in memory performance, but rather from continuous feedback about one's performance resulting from enactment.     

Verbal facilitation effects instead of verbal overshadowing in face memory of 4- to 6-year olds

Research on eye witness memory in older children and adults revealed that verbally describing unfamiliar faces impairs later recognition of these faces, known as the “verbal overshadowing effect”. The aim of this study was to investigate whether a verbal overshadowing effect occurs in 4- to 6-year olds, too, and whether visualization (i.e., drawing the seen face) might elicit a visual overshadowing effect. Instead of a verbal overshadowing effect, a verbal facilitation effect was revealed with verbal intelligence being a significant predictor for recognition accuracy in the verbalization group but not in the control group. No effect of visualization was observed on recognition accuracy. Potential explanations for the results are discussed.     

Belief in a just world and wellbeing in Indian schools

This study investigates the meaning of belief in just world (BJW) for students' subjective justice experiences with their parents and teachers and for students' subjective well-being. The hypotheses tested were that the more strongly students endorse BJW, the less the distress at school and depressive symptoms they experience. Two dimensions of BJW were assessed: personal BJW, reflecting the belief that events in one's own life are generally just, and general BJW, reflecting the belief that the world is basically a just place. The participants were 278 Indian students attending ten 10th grade classes at two private English-medium schools. The results showed that only the personal BJW, not the general BJW, was important in explaining justice experiences and wellbeing. The more the students endorsed the belief in personal just world, the more they felt treated justly by their teachers and their parents alike, and the less distress at school and depressive symptoms they experienced. In addition, teacher justice, but not parent justice, explained distress at school. Finally, the effect of personal BJW on depressive symptoms was partly mediated by both teacher and parent justice. This pattern of results persisted when class effects were controlled. Overall, this pattern of results emphasizes the importance of the individual and subjective experience of justice of the teacher behavior for adolescent wellbeing. Implications for further studies on BJW and wellbeing at school are discussed.     

Differential responses to con- and allospecific visual cues in juvenile ravens (Corvus corax): the ontogeny of gaze following and social predictions

Animal Cognition - Gaze following refers to the ability to co-orient with others’ gaze directions. Ontogenetic studies on gaze following in animals have predominantly used human experimenters...     

The Role of School-based Group Mentoring in Promoting Resilience among Vulnerable High School Students

This study examined the role of participation in a year-long school-based group mentoring program, Project Arrive (PA), on increasing resilience during the first year of high school among students identified as being at high risk for school dropout. Participants were 114, ninth grade students taking part in one of 32 PA mentoring groups, and 71 statistically matched comparison students (53% male, 75% eligible for free/reduced-price lunch, 62% Latinx). Using a propensity score with inverse probability of treatment weighting (IPTW) to reduce selection bias, and a multi-level model to account for non-independence of data within mentoring groups, we examined changes from pre-test to program exit on seven external resilience resources (developmental supports and opportunities) and four internal resilience assets (personal strengths). At program exit, PA participants had higher adjusted means than comparisons on six external resources, including school support, school belonging, school meaningful participation, peer caring relationships, prosocial peers, and home meaningful participation. PA participants also had higher adjusted means on one internal asset, problem solving. Results point to the promise of group mentoring as an approach for increasing resilience among academically vulnerable adolescents.
