Haptic object matching by blind and sighted adults and children

The present study describes a tactual object matching task based on the study of Lederman and Klatzky (1987) for the dimensions Exact shape, Weight, Volume and Texture. Participants were congenitally blind children and their sighted classmates, congenitally blind adults and sighted adults. To study a possible effect of familiarity the task was performed four times. Based on Millar's CAPIN (Convergent Active Processes in Interrelated Networks) model of spatial processing (Millar, 1994) it was thought that this manipulation would add redundant information to the experiment from which the children and blind participants could benefit. The results showed that accuracy was affected more by age than visual status, especially for the dimension Exact Shape. With regard to response times, children were in most cases faster than adults, especially the sighted adults. Familiarization had a significant effect on response times for all dimensions. Extra exercise only increased accuracy for the dimension Texture. These results were generally in line with the CAPIN model.     

Old and new ways to study characteristics of reading disability: The case of the nonword-reading deficit

Theoretical and computational models of reading have traditionally been informed by specific characteristics of disabled readers. One of the most frequently studied marker effects of developmental dyslexia is the nonword-reading deficit. Disabled readers are generally believed to show a specific problem in reading nonwords. This study presents a survey of frequently cited methods used to examine this effect by controlling general reading ability in various ways. An extensive analysis, however, shows that the majority of these methods (grade equivalents scores, the reading-level match design, and interactions in a chronological-age match design) actually fail to account for confounding variables such as age and general slowing, potentially affecting the conclusions reached. To alleviate this problem, an alternative method is presented: i.e. state trace analysis. Applying this method in a sample of Dutch disabled and typical readers, the results revealed an absence of a nonword-reading deficit in the disabled readers. Furthermore, after controlling for their decoding ability, disabled readers showed inferior word reading performance, which strongly suggests that the fundamental problem of disabled readers does not relate to the reading of nonwords but concerns their (dis)ability to acquire orthographic (word-specific) knowledge. Further, predictions for disabled readers in an inconsistent orthography like English are formulated. Finally, based on a review of neurobiological studies, implications for theories of reading disability are discussed.     

Diversity mindsets and the performance of diverse teams

Diversity can enhance as well as disrupt team performance. Diversity beliefs and climates may play an important moderating role in these effects, but it is unclear what form these should take to promote the positive effects of diversity. Addressing this question in an integration of research in team cognition and diversity, we advance the concept of diversity mindsets, defined as team members’ mental representations of team diversity. These mindsets capture diversity-related goals and associated procedural implications for goal achievement. We develop theory about the accuracy, sharedness, and awareness of sharedness of mindsets as moderators of the diversity-performance relationship. We also identify the determinants of these aspects of diversity mindsets. Finally, we discuss the implications of our model for the management of diversity.     

Nonverbal signals speak up: Association between perceptual nonverbal dominance and emotional intelligence

Emotional communication uses verbal and nonverbal means. In case of conflicting signals, nonverbal information is assumed to have a stronger impact. It is unclear, however, whether perceptual nonverbal dominance varies between individuals and whether it is linked to emotional intelligence. Using audiovisual stimulus material comprising verbal and nonverbal emotional cues that were varied independently, perceptual nonverbal dominance profiles and their relations to emotional intelligence were examined. Nonverbal dominance was found in every participant, ranging from 55 to 100%. Moreover, emotional intelligence, particularly the ability to understand emotions, correlated positively with nonverbal dominance. Furthermore, higher overall emotional intelligence as well as a higher ability to understand emotions were linked to smaller reaction time differences between emotionally incongruent and congruent stimuli. The association between perceptual nonverbal dominance and emotional intelligence, and more specifically the ability to understand emotions, might reflect an adaptive process driven by the experience of higher authenticity in nonverbal cues.     

Unraveling Effects of Novelty on Creativity

Novelty is inherent to creative processes. A positive effect of novelty on creative task performance was therefore predicted. However, creativity can benefit from divergent, as well as convergent thinking. Subsequently, novelty may benefit creative performance when divergent thinking is required, but it could inhibit creative performance when convergent thinking is required. In Study 1, participants were primed with novelty or familiarity, and performed a creativity task that required divergent thinking. Results showed a beneficial effect of novelty priming on originality of the answers. In Study 2, a creativity task that required convergent thinking was framed as novel, familiar, or neutral. Results showed an inhibitory effect of novelty on creativity. Results are related to information processing styles, and implications for creativity and novelty research are discussed.     

Early Reminiscing in Cultural Contexts: Cultural Models,Maternal Reminiscing Styles,and Children's Memories

The present study examined conversations of 164 mothers from seven different cultural contexts when reminiscing with their 3-year-old children. We chose samples based on their sociodemographic profiles, which represented three different cultural models: (1) autonomy (urban middle-class families from Western societies), (2) relatedness (rural farming families from non-Western societies), and (3) autonomy-relatedness (urban middle-class families from non-Western societies). The results showed that mothers from the autonomous contexts predominantly adopted an elaborative-evaluative reminiscing style (variable-oriented approach) and pattern (person-oriented approach). Mothers from the relational contexts mainly adopted a repetitive reminiscing style and pattern. There was greater heterogeneity for style variables among mothers from autonomous-relational contexts; in addition, the person-oriented approach revealed that the majority of mothers from autonomous-relational contexts showed hybrid style patterns. Thus, the cultural models, and their respective orientations towards autonomy and relatedness, were reflected in the way mothers reminisced with their children. The children's provision of memory elaborations was high in the autonomous contexts, low in the relational contexts, and moderate in the autonomous-relational contexts. Across contexts, maternal evaluations prompted children to contribute memory elaborations. Maternal elaborations were an additional predictor for children's memory, but only for families from the relational cultural model.     

Age-related differences in recognition memory: effects of materials and context change

The study explored age-related differences in the effects of context change on recognition memory by presenting object names (Expt. 1A) or their pictures (Expt. 1B) on background scenes. Participants later attempted to recognize previously presented items on background scenes that were original, switched, blank, or new. Older adults recognized fewer word stimuli than did younger adults, and context effects were larger for older adults. With pictures, however, the age-related decrement was eliminated and context effects were reduced. The beneficial effect of context reinstatement in older adults occurs despite the finding that they are less able to recall or recognize such contexts (Experiment 2). Older adults can use context information in recognition memory at least as efficiently as younger adults when suitable materials and conditions are provided.     

Comparison of arousal and preference assessment outcomes for sex offenders with intellectual disabilities

We compared outcomes of arousal and preference assessments for five adult male alleged sexual offenders with intellectual disabilities. Arousal assessments involved the use of the penile plethysmograph to measure changes in penile circumference to both deviant (males and females under the age of 18) and nondeviant (males and females over the age of 18) video clips. Paired‐stimulus preference assessments were arranged to present still images from the video clips used in the arousal assessments. Results showed correspondence between the assessments for four out of the five participants. Implications are discussed for the use of preference assessment methodology as a less intrusive assessment approach for sexual offender assessments.     

Psychological processes in young bullies versus bully‐victims

Some children who bully others are also victimized themselves (“bully‐victims”) whereas others are not victimized themselves (“bullies”). These subgroups have been shown to differ in their social functioning as early as in kindergarten. What is less clear are the motives that underlie the bullying behavior of young bullies and bully‐victims. The present study examined whether bullies have proactive motives for aggression and anticipate to feel happy after victimizing others, whereas bully‐victims have reactive motives for aggression, poor theory of mind skills, and attribute hostile intent to others. This “distinct processes hypothesis” was contrasted with the “shared processes hypothesis,” predicting that bullies and bully‐victims do not differ on these psychological processes. Children (n = 283, age 4–9) were classified as bully, bully‐victim, or noninvolved using peer‐nominations. Theory of mind, hostile intent attributions, and happy victimizer emotions were assessed using standard vignettes and false‐belief tasks; reactive and proactive motives were assessed using teacher‐reports. We tested our hypotheses using Bayesian model selection, enabling us to directly compare the distinct processes model (predicting that bullies and bully‐victims deviate from noninvolved children on different psychological processes) against the shared processes model (predicting that bullies and bully‐victims deviate from noninvolved children on all psychological processes alike). Overall, the shared processes model received more support than the distinct processes model. These results suggest that in early childhood, bullies and bully‐victims have shared, rather than distinct psychological processes underlying their bullying behavior.     

Evaluation of the effectiveness of an anti‐bullying programme in primary schools

A nationwide programme to prevent and manage bullying in Irish schools, based on that implemented in Norway in 1996, is currently being developed, and pilot work with a sample of primary schools within a single county of Ireland has been conducted and evaluated (the staff and pupils of 42 primary schools having been involved). A network of professionals (11 teachers) were trained to co‐ordinate the anti‐bullying programme in the schools, subsequent activities involving their training teachers (a total of 197) and parents in three to five schools each. In evaluation, pupils from 22 of the schools completed modified versions of the Olweus Bully/Victim Questionnaire [Olweus, 1989; Whitney and Smith, 1993]. Teachers completed a questionnaire (concerning their knowledge and feelings about bullying [Rigby, 1997]) both before and after the implementation of the anti‐bullying training programme. Significant reductions were found in pupils' reports of having been victimised after the implementation of the programme. Overall, 19.6 per cent fewer children were victimised. There was a reduction of 50.0 per cent amongst those frequently victimised within the last school term, and of 43.0 per cent in reports of having been bullied within the last five school days. A reduction of 17.3 per cent in pupils' reports of having taken part in bullying others was also observed after the implementation of the programme. There were, in particular, significant reductions (69.2 per cent) in reports of frequently bullying others within the last school term, and of 51.8 per cent in reports of having taken part in bullying others within the last five school days. Whilst the programme was shown to reduce the incidence of pupils' involvement in bullying behaviour, the perennial challenge of attempting to increase the levels of pupils' reporting of bullying to teachers and parents remains a challenge for the authors to attend to in the further development of the nationwide anti‐bullying programme.
