Personality and prejudice: Extension to the HEXACO personality model

We modelled the associations between the HEXACO dimensions of personality, Social Dominance Orientation (SDO), Right‐Wing Authoritarianism (RWA) and prejudice towards dangerous, derogated and dissident groups (N = 454 undergraduates). Consistent with a Big‐Five model, low Openness to Experience predicted RWA and therefore dangerous and dissident group prejudice. As predicted, low Emotionality (and Openness) rather than Agreeableness predicted SDO and therefore derogated and dissident group prejudice. Comparison with meta‐analytic averages of Big‐Five data supported expected similarities and differences in the association of Big‐Five and HEXACO models of personality with ideology. Finally, Honesty‐Humility simultaneously predicted increases in RWA but decreases in SDO, and thus opposing effects on prejudice. These opposing effects have gone unidentified in research employing Big‐Five models of personality structure. Copyright © 2010 John Wiley & Sons, Ltd.     

Evidenzbasierte Psychotherapie der Depression

Depressive disorders are among the most frequent reasons for utilizing the health care system. Despite the availability of efficacious treatments and further advances throughout the last years, there is still a need for improving diagnostic and therapeutic procedures. A promising approach is the implementation of evidence- and consensus-based guidelines. The German “Nationale VersorgungsLeitlinie Unipolare Depression” are evidence- and consensus-based clinical practise guidelines for patients with unipolar depression. All relevant stakeholders have been involved in its development and have passed the final version at the end of 2009 to foster compliance throughout. The available evidence allows the derivation of differentiated treatment recommendations, also with regard to concomitant antidepressant medication or as alternative treatment options. In acute therapy watchful waiting over 14 days is recommended for mild depression and psychotherapy after persistence of symptoms. In cases of moderate depression, psychotherapy and pharmacotherapy are equally recommended, in cases of severe depression a combination of both is recommended.     

Perceived Parenting,Self-Esteem,and General Self-Efficacy of Iranian American Adolescents

We examined whether Iranian American adolescents’ perceptions of parental support, parental knowledge, and parental psychological control relate to general self-efficacy directly, and indirectly through positive esteem and self-deprecation. To investigate this, self-report surveys were collected from 158 Iranian American adolescents attending Iranian American youth groups, Armenian private school, and one public school. Results indicated that positive esteem, self-deprecation, mother and father knowledge, and mother and father psychological control were directly related to general self-efficacy. Furthermore, the parenting variables were indirectly related to general self-efficacy through either positive esteem or self-deprecation.

Towards defining a unified concept for the acceptability of Intelligent Transport Systems (ITS): A conceptual analysis based on the case of Intelligent Speed Adaptation (ISA)

A key success factor in the future implementation of new in-vehicle technologies is in understanding how users will experience and respond to these devices. Although it is recognized that acceptance, acceptability and/or support is important, consistency in the definition of acceptability, and how it can be measured, is absent. In this paper we conceptualize acceptance as the attitudes towards a new device after its introduction and acceptability as the attitudes to it before its introduction. It is our goal to describe and conceptualize the most common and relevant socio-psychological factors that can influence acceptance and acceptability of Intelligent Speed Adaptation (ISA). By analysing the different theories and methods used in ISA trials we arrived at the 14 most potential indicators that could influence the definition of acceptability and acceptance. A test survey was conducted to determine if these indicators are relevant and if they affect acceptability. The use of a factor analysis helped to single out those questions that were deemed relevant in doing our conceptual acceptability analysis, and to allocate correlations between the different items. We conclude that we have found a concept with some main possible indicators that directly influence the acceptability of ISA.     

Poor performance on cognitive tasks in depression: Doing too much or not enough?

Depressed people perform poorly on cognitive tasks. It is unclear whether these deficits are due to decreased devotion of task-related resources or to increased attention to non-task-related information. In the present study, we examined the degree to which depressed and healthy adults displayed pupillary motility that varied at the frequency of presented stimuli on a cognitive task, which we interpreted as task-related processing, and at other frequencies, which we interpreted as reflecting intrinsic processing. Depressed participants made more consecutive errors than did controls. More pupillary motility at other frequencies was associated with poorer performance, whereas more pupillary motility at the frequency of presented stimuli was associated with better performance. Depressed participants had more pupillary motility at other frequencies, which partially mediated observed deficits in cognitive performance. These findings support the hypothesis that allocating cognitive resources to intrinsic processing contributes to observed cognitive deficits in depression.     

Auditory verbal hallucinations: Dialoguing between the cognitive sciences and phenomenology

Auditory verbal hallucinations (AVHs) are a highly complex and rich phenomena, and this has a number of important clinical, theoretical and methodological implications. However, until recently, this fact has not always been incorporated into the experimental designs and theoretical paradigms used by researchers within the cognitive sciences. In this paper, we will briefly outline two recent examples of phenomenologically informed approaches to the study of AVHs taken from a cognitive science perspective. In the first example, based on Larøi and Woodward (Harv Rev Psychiatry 15:109–117, 2007), it is argued that reality monitoring studies examining the cognitive underpinnings of hallucinations have not reflected the phenomenological complexity of AVHs in their experimental designs and theoretical framework. The second example, based on Jones (Schizophr Bull, in press, 2010), involves a critical examination of the phenomenology of AVHs in the context of two other prominent cognitive models: inner speech and intrusions from memory. It will be shown that, for both examples, the integration of a phenomenological analysis provides important improvements both on a methodological, theoretical and clinical level. This will be followed by insights and critiques from philosophy and clinical psychiatry—both of which offer a phenomenological alternative to the empiricist–rationalist conceptualisation of AVHs inherent to the cognitive sciences approach. Finally, the paper will conclude with ideas as to how the cognitive sciences may integrate these latter perspectives into their methodological and theoretical programmes.     

A REFINED COMPUTER HARASSMENT PARADIGM: VALIDATION, AND TEST OF HYPOTHESES ABOUT TARGET CHARACTERISTICS

A refined computer paradigm for assessing sexual harassment is presented, validated, and used for testing substantive hypotheses. Male participants were given an opportunity to send sexist jokes to a computer-simulated female chat partner. In Study 1 ( N = 44), the harassment measure (number of sexist jokes sent) correlated positively with self-reported harassment proclivity. Study 2 ( N = 77) included a more elaborate cover story, variations of the female target's attitude (feminist vs. traditional) and physical attractiveness (low vs. high), and additional measures for construct validation. Results showed that harassment correlated positively with self-reported harassment proclivity, hostile sexism, and male identity. Feminist targets were harassed more than traditional targets, whereas target attractiveness had no effect. Theoretical and applied implications are discussed.     

The Development of Hyperactive–Impulsive Behaviors During the Preschool Years: The Predictive Validity of Parental Assessments

The objectives of this study were to establish the different developmental trajectories of hyperactive-impulsive behaviors on the basis of both mother and father ratings at 19, 32, 50, and 63 months, and to examine the predictive validity of these trajectories with respect to later hyperactive-impulsive behaviors, as rated by teachers in the first 2 years of school. Hyperactive-impulsive behaviors were assessed in a population-based sample of 1,112 twins (565 boys and 547 girls) at 19, 32, 50, and 63 months of age. The results revealed a differentiated and consistent view of developmental trajectories of hyperactive-impulsive behaviors derived from these repeated assessments, with 7.1% of children seen by mothers (7% for fathers) as displaying high and stable hyperactive-impulsive behaviors. According to mother ratings, children on a high-chronic trajectory were more likely than other children to display hyperactive-impulsive behaviors at 72 and 84 months according to their teachers. Repeated measures over time and father-based trajectories significantly added to the prediction teacher later ratings of hyperactive-impulsive behaviors. These results support the predictive validity of parental assessment of hyperactive-impulsive behaviors during the preschool years and their use to identify children at risk for further evaluation and possible intervention.     

Social problem‐solving skills as a mediator between executive function and long‐term social outcome following paediatric traumatic brain injury

There is debate regarding the relationship between executive function and social outcome following paediatric traumatic brain injury (TBI), due to inconsistent findings in the literature. It has been suggested that these contradictory results may reflect the absence of an established mechanism to explain this relationship. Yeates and colleagues (2004) proposed a possible model in which the maturity of social problem‐solving skills mediates the relationship between executive function and social outcome. The current study aimed to explore this model and determine whether social problem solving mediates the relationship between executive function and social outcome in a TBI population. The sample consisted of 36 adolescents and young adults who sustained a TBI between 8 and 12 years of age. They ranged between 16 and 22 years of age and were 7–10 years post‐injury. Findings indicated that a higher level of executive dysfunction was associated with less sophisticated social problem‐solving skills and poorer social outcome. Further, the maturity of social problem‐solving skills was found to mediate the relationship between executive function and social outcome in this group.
