Familiarity breeds distortion: the effects of media exposure on false reports concerning media coverage of the terrorist attacks in london on 7 July 2005

The present experiment investigated whether increased media exposure could lead to an increase in memory distortions regarding a traumatic public event: the explosion of the No. 30 bus in Tavistock Square, London on 7 July 2005. A total of 150 Swedish and 150 UK participants completed a series of questionnaires about their memory of either (i) the aftermath of the explosion, (ii) a non-existent computerised reconstruction of the moment of the explosion, or (iii) non-existent closed circuit television footage of the moment of the explosion. In line with the availability heuristic, U.K. participants were more likely than Swedish participants to claim to have seen all three types of footage. Furthermore, a subsample of U.K. participants who appeared to have developed false "memories" of seeing the No. 30 bus explode scored significantly higher on measures of dissociation and fantasy proneness than participants who did not develop false "memories". This experiment provides further support for the role of imaginative processes in the development of false memories.     

Religious identity development of adolescents in religious affiliated schools. A theoretical foundation for empirical research

The question, how religious affiliated schools for secondary education shape religious education and what effects this education has on the religious identity development of pupils, is relevant in a time when the position of religious affiliated schools is highly disputable. In earlier empirical research on religious identity development of adolescence, hardly any attention was paid to the theoretical framework of this question. Therefore, connections are sought with the identity theory of Erikson and with operationalizations of his theory by Marcia and others. The key concepts are ‘exploration’ and ‘commitment’. Religious identity development is seen from a pragmatic perspective in which the transactional relation of individuals and environment is stressed.     

Adverse effects of predictive testing for Huntington disease underestimated: long-term effects 7-10 years after the test.

The 7-10-year psychological effects of presymptomatic testing for Huntington disease are described in 142 individuals and 104 partners. Questionnaires included the Beck Hopelessness Scale (A. T. Beck, A. Weissman, D. Lester, & L. Trexler, 1974), the Impact of Event Scale (M. J. Horowitz, N. Wilner. & W. Alvarez. 1979). and the General Health Questionnaire (D. P. Goldberg. 1972). Carriers and their partners were more distressed immediately after the test result, although their outlooks improved somewhat in the 2-3-year posttest period. However, they became more pessimistic thereafter, when approaching the age of onset. Carriers, who were lost to follow-up after disclosure of test results, reported more distress pretest than did retained carriers. This demonstrates that studies that report few harmful effects may have underestimated the real impact. Moreover, follow-up studies need to investigate time effects for longer than a few years.     

Incremental grouping of image elements in vision

One important task for the visual system is to group image elements that belong to an object and to segregate them from other objects and the background. We here present an incremental grouping theory (IGT) that addresses the role of object-based attention in perceptual grouping at a psychological level and, at the same time, outlines the mechanisms for grouping at the neurophysiological level. The IGT proposes that there are two processes for perceptual grouping. The first process is base grouping and relies on neurons that are tuned to feature conjunctions. Base grouping is fast and occurs in parallel across the visual scene, but not all possible feature conjunctions can be coded as base groupings. If there are no neurons tuned to the relevant feature conjunctions, a second process called incremental grouping comes into play. Incremental grouping is a time-consuming and capacity-limited process that requires the gradual spread of enhanced neuronal activity across the representation of an object in the visual cortex. The spread of enhanced neuronal activity corresponds to the labeling of image elements with object-based attention.     

Young Children's Descriptions of God: Influences of parents' and teachers' God concepts and religious denomination of schools

This study extends prior research on antecedents of individual differences in God concepts in early childhood by examining relations of parents' and teachers' God concepts and religious denomination of schools with children's God concepts. Participants were 165 preschoolers (mean age 63 months), 107 of their parents and 16 teachers. These subjects were distributed over eight elementary schools belonging to four different religious denominations, i.e. Catholic, Dutch Reformed, Orthodox Reformed and State schools. The God concepts of children, parents and teachers were measured using interviews and questionnaires. Results showed that both parents' and teachers' God concepts were predictive of children's God concepts, but each in a different way. Parents seem to influence the relational component of children's God concepts particularly. Teachers especially contribute to biblical content of children's God concepts. Religious denomination of schools had independent effects on children's God concepts, controlling for parental denomination.     

Reciprocal Associations between Parenting Challenges and Parents' Personality Development in Young and Middle Adulthood

Having children affects many aspects of people's lives. However, it remains unclear to what degree the challenges that come along with having children are associated with parents' personality development. We addressed this question in two studies by investigating the relationship between parenting challenges and personality development in mothers of newborns (Study 1, N = 556) and the reciprocal associations between (mastering) parenting challenges and personality development in parents of adolescents (Study 2, N = 548 mothers and 460 fathers). In Study 1, we found the stress of having a newborn baby to be associated with declines in maternal Agreeableness, Conscientiousness, and Emotional Stability. Parenting challenges were also related to personality development in parents of adolescent children in Study 2, with parent–child conflict being reciprocally associated with decreases in Conscientiousness and Emotional Stability. Mastering parenting challenges in the form of high parenting self‐efficacy, on the other hand, was found to be associated with increases in Agreeableness, Conscientiousness, and Emotional Stability, and vice versa. In sum, our results suggest that mastering the challenges associated with the social role of parenthood is one of the mechanisms underlying personality development in young and middle adulthood.

Witnesses stumbling down memory lane: The effects of alcohol intoxication,retention interval,and repeated interviewing

Intoxicated eyewitnesses are often discredited by investigators and in court, but few studies have examined how alcohol affects witnesses’ memory. The primary aim of the present study was to examine how intoxication (alcohol vs. control), retention interval (immediate vs. one week delay), and number of interviews (one vs. two interviews) affect witnesses’ memory. The participants (N?=?99) were randomly assigned to consume either orange juice or alcohol mixed with orange juice, and they all witnessed a filmed mock crime afterwards. The recall took place either (a) immediately and after a one week delay or (b) after a one week delay only. No main effect of alcohol was found on the quantity or quality of the witnesses’ statements. Both intoxicated and sober witnesses recalled more details, and were more accurate, during immediate compared to delayed recall. For witnesses interviewed twice, an average of 30% new details were provided in the second compared to the first interview, and these were highly accurate. In sum, contrary to what one can expect, intoxicated witnesses with a low to moderate blood alcohol concentration (below 0.10%) were reliable witnesses.     

Well-being and Need for Support of Adolescents with a Chronically Ill Family Member

This study investigates whether there are differences in the well-being, need for help and use of support services between adolescents with and without a chronically ill or disabled family member. It also examines the role played by the type of illness, the relationship to the family member and the nature and intensity of the help provided by the adolescent. A Dutch sample of 1581 adolescents (average age 14.6?years) completed a questionnaire in 2010 about mental health problems, pro-social behavior, need for and use of support and the illness of family members and any care tasks performed by the respondent. Young people with a sick family member had more mental health problems than their counterparts without a chronically ill family member. They also reported a greater need for and use of help and support. Performing domestic tasks was found to be a predictor for overall mental health problems. The intensity of the help given was related to the need for help by the adolescent. It is concluded that growing up with a chronically ill family member and spending a lot time performing (domestic) tasks are risk factors for adolescent mental health problems and adolescents’ need for help. Special attention is warranted for those who need support but who do not translate that need into reality by seeking help.
