Concurrent Verbal and Emotion Laterality Effects Exhibited by Normally Achieving and Learning Disabled Children

This study assessed both left- and right-hemisphere functions simultaneously when two-syllable words differing only in the initial stop consonant and spoken in different emotional tones were paired dichotically. Seventy-two right-handed normally achieving children, 12 boys and 12 girls at each of grades 1, 3, and 5, were instructed to detect either the presence of a specific word or of a specific emotion. In addition, 30 right-handed learning disabled (LD) children (age-matched to the normal controls) were assessed to determine whether LD children distribute verbal and nonverbal functions to different hemispheres. Results indicated that although both control and LD children demonstrated an overall REA for word stimuli and an LEA for emotional stimuli, and that emotional stimuli were easier to process than word stimuli, LD children were less accurate in processing both types of stimuli than their control counterparts. ‘Complementary specialization,’ as assessed through distribution of laterality effects, was found to be greater for control children than for LD children. However, the lack of consistency in complementary specialization found among the three developmental grade levels may be indicative that independent brain mechanisms underlying verbal and emotional processing have yet to be fully established in children. Further, in contrast to adult findings, a larger LEA was obtained for the emotion ‘happy’ than for the emotion ‘sad.’ It was concluded that whereas independent hemisphere processing for words and emotions is somewhat prevalent for control children, LD children might not be as strongly lateralized for opposite hemisphere processing of these functions.     

Consumer recycling: An ethical decision‐making process

Although recycling is often experienced as a moral dilemma, studies that systematically approach this issue from an ethical perspective are scarce. Moreover, previous studies have explored recycling by mainly using single ethical constructs, such as moral norms, values or obligations, rarely approaching it as an ethical decision‐making process. Our study takes a more holistic approach and integrates the recycling literature with business ethics theory in order to develop a conceptual model of ethical decision making involved in recycling. The model is based on Jones' issue‐contingent model and its key concept, that is, moral intensity, which we extend by adding altruism as an important personality trait that influences pro‐social behaviour. The data were collected from a sample of 367 adult consumers, representative of the Slovenian population by gender and age. The hypotheses were tested using structural equation modelling. The results of our study confirmed the relationships between three key facets of ethical decision making: moral recognition, moral judgment and moral intention. Higher levels of moral recognition were found to lead to more positive moral judgments, which in turn positively influenced the formation of intentions to recycle. Moreover, moral intensity was found to be a significant predictor of moral recognition and moral judgment, while altruism was found to be a significant predictor of moral recognition. These findings hold important implications for public policy makers and social marketers who have to consider not only the consumer characteristics but also the issue characteristics in seeking to understand and influence consumer recycling.

Comparison Facilitates Children's Learning of Names for Parts

Learning names for parts of objects can be challenging for children, as it requires overcoming their tendency to name whole objects. We test whether comparing items can facilitate learning names for their parts. Applying the structure-mapping theory of comparison leads to two predictions: (a) young children will find it easier to identify a common part between two very similar items than between two dissimilar items (because the similar pair is easier to align); (b) close alignments potentiate far alignments: children will be better able to extend a novel part name to a dissimilar object after having extended it to a similar object. In three studies, 227 preschool children mapped novel part terms to new animals or objects. Both predictions were confirmed. Children more accurately extended novel part terms to objects that were similar to the standard than to objects that were dissimilar (Experiments 1 and 2), and children more accurately extended novel part names to dissimilar objects after having extended them to similar objects (Experiment 3). We conclude that structure-mapping processes can support part learning.     

Out of Sight Is Not Out of Mind: Developmental Changes in Infants' Understanding of Visual Perception During the Second Year

Three experiments investigated 14-, 18-, and 24- month-old infants' understanding of visual perception. Infants viewed films in which a protagonist was either able to view the location of a hidden object (Visual Access condition) or was blindfolded when the object location was revealed (No Visual Access condition). When requested to find the object, the protagonist pointed either at the correct location or at the incorrect location. Across experiments, 18-month-olds looked longer at the unexpected action (e.g., person pointing at the incorrect location in the Visual Access condition). By 24 month of age, infants could infer the correct search behavior from gaze alone. These findings suggest that by the middle of the second year of life, infants understand the psychological relation between an observer and an object, even if the object is no longer visible.     

The Effect of Action Valence and Race on 3- to 8-Year-Old Children's Social Cognitive Judgments

The present study investigated children's judgments of actions as a function of the valence of the action and the race of the actor. Three- to 8-year-old children were read an illustrated storybook in which 1 character did not share (a negatively valenced action) and the other character was helpful (a positively valenced action). The race of the characters was manipulated such that in the story, there was 1 Black character and 1 White character. Children were asked to make judgments about how mean/nice the characters were and what consequence (reward or punishment) they should receive for their actions. Despite the fact that children of this age show explicit and implicit pro-White biases (e.g., Baron & Banaji, 2006 Baron, A. S., & Banaji, M. R. (2006). The development of implicit attitudes: Evidence of race evaluations from ages 6 and 10 and adulthood. Psychological Science, 17, 53–58. doi:10.1111/j.1467-9280.2005.01664.x[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), children's judgments were based solely on the valence of action and not on character race. The findings are discussed in light of moral development and the development of bias as it pertains to race.     

Breaking up is Hard to do,Especially for Strongly “Preoccupied” Lovers

Abstract

Is a relationship breakup harder on certain people? To address this question, the present study investigated the relationship of individuals’ attachment styles to various reported aspects of a relationship's dissolution: initiation of the breakup, emotional reactions to the breakup, reasons for the breakup, and experiences and perceptions following the breakup. One hundred nineteen undergraduates completed an extensive questionnaire concerning a past romantic relationship that had broken up. Feeney, Noller, and Hanrahan's (1994) Attachment Style Questionnaire (ASQ) provided continous measures for five attachment styles or “attitudes”: confidence, discomfort with closeness, need for approval, preoccupation with relationships, and relationships as secondary. Principal-components analyses served to derive criterion indexes from the breakup questionnarie measures, which were individually regressed on the five ASQ scales. As predicted form attachment theory, respondents scoring high on preoccupation with relationships (reflcting anxious/ambivalent attachment) showed distinctive responses to the relationship breakup, in contrast to those scoring high on other attachment styles. Specifically, those strongly preoccupied with relationships reported (a) that their partner was unhappy in the relationship and had initiated the breakup, (b) having experienced difficulty adjusting to the breakup and felling it had been a mistake, and (c) more negative emotion and less positive emotion following the breakup. Implications of these findings are discussed     

Childhood Sexual Abuse and Revictimization In Adolescence and Adulthood

Abstract

Childhood sexual abuse must be seen as a pervasive risk factor in children's lives: No demographic or family characteristics have as yet been identified to rule out the possibility that a child will be or has been sexually abused (Finkelhor, 1993). The adverse consequences of sexual abuse, both immediate and long term, have been documented by a large body of research. After a summary of the main findings from this research, the main objective of the present chapter is to examine the impact of childhood sexual abuse on a particular aspect of psychological functioning: the development of sexual behavior and sexual relationships. In this analysis, special consideration is given to the question of whether individuals who were sexually abused as children are at greater risk of experiencing sexual victimization in later life than individuals without experience of abuse. This question has generated a substantial body of evidence (see Messman & Long, 1996, for a review), and researchers are beginning to understand pathways from the experience of abuse in childhood to revictimization in adolescence and adulthood.     

Small subitizing range in people with Williams syndrome

Recent evidence suggests that the rapid apprehension of small numbers of objects—often called subitizing—engages a system which allows representation of up to 4 objects but is distinct from other aspects of numerical processing. We examined subitizing by studying people with Williams syndrome (WS), a genetic deficit characterized by severe visuospatial impairments, and normally developing children (4–6.5 years old). In Experiment 1, participants first explicitly counted displays of 1 to 8 squares that appeared for 5 s and reported “how many”. They then reported “how many” for the same displays shown for 250 ms, a duration too brief to allow explicit counting, but sufficient for subitizing. All groups were highly accurate up to 8 objects when they explicitly counted. With the brief duration, people with WS showed almost perfect accuracy up to a limit of 3 objects, comparable to 4-year-olds but fewer than either 5- or 6.5-year-old children. In Experiment 2, participants were asked to report “how many” for displays that were presented for an unlimited duration, as rapidly as possible while remaining accurate. Individuals with WS responded as rapidly as 6.5-year-olds, and more rapidly than 4-year-olds. However, their accuracy was as in Experiment 1, comparable to 4-year-olds and lower than older children. These results are consistent with previous findings, indicating that people with WS can simultaneously represent multiple objects, but that they have a smaller capacity than older children, on par with 4-year-olds. This pattern is discussed in the context of normal and abnormal development of visuospatial skills, in particular those linked to the representation of numerosity.     

Substitutes for leadership in anaesthesia teams and their impact on leadership effectiveness

In this study we aim to increase our understanding of leadership in anaesthesia teams by investigating the relationship between substitutes for leadership, leadership behaviour, and team performance in situations with varying levels of routine and standardization. The present study relied on video recordings of 12 anaesthesia teams in a simulated setting with the occurrence of a nonroutine event. Clinical team performance was measured by the speed of adequate team reaction to this event. The leadership behaviours observed were coded either as content oriented (e.g., information transmission) or structuring (e.g., assigning tasks). Results showed that leadership behaviour changed depending upon the level of routine of a situation, the degree of standardization, and, to some extent, on the experience of team members. Leadership tends to be positively related to team performance during nonroutine and low standardized situations but negatively related to team performance in routine and highly standardized situations. Furthermore, leadership is only slightly related to team member experience. This study improves our understanding of influences of substitutes for leadership on successful leadership behaviour in anaesthesia teams. The findings also lead to suggestions for both further research and the enhancement of team leadership in critical care.     

Demands,resources, and work ability: A cross-national examination of health care workers

Understanding work ability, with the goal of promoting it, is important for individuals as well as organizations. It is especially important to study work ability in health care workers, who face many work-related challenges that may threaten work ability. We studied various job demands, job resources, and interactions of demands and resources relating to work ability using the Job Demands–Resources model as a framework. Acute care health care workers from six nations (US, Australia, UK, Brazil, Croatia, and Poland) completed a survey. Role demands related to work ability in the Australia sample only, and supervisor support related to work ability in the Australia sample only. Yet, high levels of supervisor support significantly moderated (buffered) negative relationships between physical demands and work ability in the US sample, along with negative relationships between role demands and work ability in both the Croatia and UK samples. Skill discretion related to work ability in every nation sample, and therefore appears to be particularly important to work ability perceptions. In addition, skill discretion moderated (buffered) a negative relationship between role demands and work ability in the Australia sample. We therefore recommend that interventions to help preserve or improve work ability target this important job resource.
