New visuospatial associations by training verbospatial mappings in the first language

We investigated whether verbospatial and visuospatial information share a common representation. We demonstrate that when the associations from spatial words to spatial responses are altered, so that the word left becomes associated with a right response and the word right with a left response, the associations from the spatial locations left and right to the spatial responses also change. This effect was only observed for first-language spatial words (Dutch) and not for second-language spatial words (French), and it did not increase when these languages were combined. The findings argue for shared spatial representations for different types of spatial input.     

Priming reveals differential coding of symbolic and non-symbolic quantities

Number processing is characterized by the distance and the size effect, but symbolic numbers exhibit smaller effects than non-symbolic numerosities. The difference between symbolic and non-symbolic processing can either be explained by a different kind of underlying representation or by parametric differences within the same type of underlying representation. We performed a primed naming study to investigate this issue. Prime and target format were manipulated (digits or collections of dots) as well as the numerical distance between prime and target value. Qualitatively different priming patterns were observed for the two formats, showing that the underlying representations differed in kind: Digits activated mental number representations of the place coding type, while collections of dots activated number representations of the summation coding type.     

Factor Structure and Construct Validity of the Dutch Version of the Antisocial Process Screening Device

The goal of the present study was to evaluate the factor structure and construct validity of the Antisocial Process Screening Device (APSD) in a community sample of Dutch adolescents. Confirmatory factor analyses supported the two- and three-factor model, but the two-factor model (Callous-Unemotional and Impulsivity/Conduct Problems) was more parsimonious. Model fit was invariant across gender. Interrater reliability was good and internal consistency of the factors was modest to good, with the exception of the Callous-Unemotional factor. Convergence with the APSD self-report version, divergence with the Big Five personality dimensions of Agreeableness and Conscientiousness, and expected gender differences in mean APSD scores reproduced findings obtained in American samples, supporting the cross-cultural validity of the APSD.     

Personality Types and Development of Adolescents' Conflict with Friends

This study examined the development of adolescents' conflict frequency and conflict resolution with their best friends, and tested whether adolescents with different personality types differed in these developmental changes from early to middle adolescence. Dutch adolescents (N = 922, 468 boys; M_age = 12.4 years at first wave) annually filled in questionnaires for five consecutive years. Growth modelling revealed that, whereas adolescents' conflict frequency and hostile conflict resolution did not change, positive problem solving, withdrawal, and compliance during conflict with best friends increased from age 12 to 16 years. Adolescents with different personality types differed in the mean levels of conflict frequency and conflict resolution strategies. That is, resilients had less conflict with friends than undercontrollers and overcontrollers. During conflict, resilients used the least hostile conflict resolution and compliance, and employed the most positive problem solving. Undercontrollers adopted the least positive problem solving, and overcontrollers complied and withdrew the most. Using a person‐centred approach, three developmental conflict resolution types were identified based on different constellations of the four conflict resolution strategies over time. Adolescents with different personality types had different distributions on the conflict resolution types. Copyright © 2013 John Wiley & Sons, Ltd.     

Conflict detection,dual processes,and logical intuitions: Some clarifications

Recent studies on conflict detection during thinking suggest that reasoners are sensitive to possible conflict between their heuristic judgement and elementary logical or probabilistic principles. I have argued that this conflict sensitivity calls for the postulation of logical intuitions and has implications for the way we conceive the interaction between System-1 and System-2 in dual process theories. In this paper I clarify potential misconceptions about this work, discuss the link with other approaches, and sketch directions for further research.     

Cognitive-Behavioural Therapy Targeting Fear of Progression in an Interdisciplinary Care Program: A Case Study in Systemic Sclerosis

People living with chronic illness often report uncertainty about the future, fear of disease progression, fear of becoming physically disabled, and a reduced life expectancy as important sources of stress. However, little is known about psychological interventions targeting these concerns. The aim of this study is to illustrate an intervention to reduce emotional distress and concerns about the future in a patient with systemic sclerosis (SSc), a rare chronic rheumatic disease with serious consequences for most patients, and to present a preliminary report on its effectiveness using a single-case study design. Because of the complexity of symptoms and complaints due to SSc, the psychological intervention was embedded in an interdisciplinary care program also consisting of physical therapy, occupational therapy, and specialized nurse care.
