Elaboration effects in implicit and explicit memory tests

Dissociation effects in explicit and implicit tests of memory were examined in two experiments. In Experiment 1 serial-position effects were studied. Results showed that the standard primacy effect found in free recall is absent in an implicit word-stem completion test. In Experiment 2 a dissociation was found for the effect of high- and low-frequency words in free recall and word-stem completion tests. Both findings are explained in terms of a modified and extended version of the activation-elaboration learning account, which was inspired by attempts to simulate dissociation effects in connectionist models. The relationship between this account and two other leading accounts of dissociation effects in implicit and explicit memory is discussed, and a model to integrate aspects of all three accounts is suggested.     

Feasibility and Preliminary Efficacy of an Internet Support Group for Parents of a Child with Neurofibromatosis Type 1: a Pilot Study

This pilot study investigated the feasibility and preliminary efficacy of an Internet Support Group (ISG) for parents of children with NF1. Eligible parents were recruited by email and completed baseline questionnaires assessing social support, self-efficacy, depression, and anxiety. The ISG involved eight weekly 90-min chat sessions and a discussion forum open 24 h/day for 8 weeks. Follow-up measures were completed immediately post-intervention and 3 months later. Parents from 33 families (29 mothers, 4 fathers) completed baseline measures. Over half of parents (52 %) rated their child’s disease severity as mild, 33 % moderate, and 15 % severe. Among 21 parents who completed post-intervention measures, ratings of perceived emotional (p = .0008) and informational (p = .0003) support increased. There were no significant changes in self-efficacy, depression, or anxiety (ps > .05). The mean satisfaction rating was moderately high (7.6/10; range 4–10). Some parents commented that the chat sessions were at inconvenient times, which may have limited participation. Preliminary evidence in this small sample of parents suggests that ISGs may be a feasible and potentially efficacious method of providing support to parents of children with NF1. Having multiple weekly chat sessions held at various days and times may improve accessibility and participation. Clinicians are encouraged to help parents access online support resources.     

Repeated recall,retention interval and the accuracy–confidence relation in eyewitness memory

People can evaluate the quality of their memories by giving a confidence judgement concerning the perceived accuracy of what is recalled or recognised. Even when people strive for accuracy and claim great confidence they may, however, not remember what actually happened. Both accuracy and confidence can be affected by various factors. In this study, we investigated the effects of retention interval (either 1, 3 or 5 weeks delay before first testing) and of repeated questioning (initial recall after 1 week, repeated after 3 and 5 weeks) on accuracy and confidence of recall of a naturalistic videotaped event. Longer retention intervals before initial testing resulted in lower accuracy and lower confidence scores. Repeated recall, however, had little effect on accuracy and confidence. Relatively high accuracy–confidence correlations were found in all delay and repetition conditions. Practical implications of these findings for questioning eyewitnesses are discussed.

Repeated partial eyewitness questioning causes confidence inflation but not retrieval‐induced forgetting

During a crime investigation eyewitnesses are often interviewed more than once. Repeated post‐event questioning offers an opportunity for retrieval practice. Practicing retrieval of a subset of memories may suppress access to related memories, a phenomenon known as retrieval‐induced forgetting. In this short report we investigated the generalization of retrieval‐induced forgetting to episodic eyewitness memory of a complex event. The results indicated that repeated retrieval improves future recall of practiced information, but does not induce forgetting of related information. Retrieval practice, however, did result in higher confidence ratings, both for correct and incorrect answers. The practical consequence of this study is that repeated questioning should be avoided if possible. Not because it may induce retrieval‐induced forgetting, but because it may lead to confidence inflation. Copyright © 2008 John Wiley & Sons, Ltd.     

Self-reported suicidal behavior in Dutch secondary education students

From nearly 10,000 secondary education students in The Netherlands, aged 14-20, data were collected on the prevalence of suicide attempts and recent thoughts about suicide and death. In this sample, 3.3% of the girls and 1.3% of the boys indicated that they had attempted suicide. The youngest students already reported as many attempts as the eldest, which is remarkable. Differences between boys and girls and between various types of schools were not substantial. We also found that 5.2% of the girls and 2.2% of the boys currently had thoughts of suicide. Again, there was no substantial difference as regards sex, type of school, and age. There was, however, a (small) difference between boys and girls concerning thoughts of death--namely, 9.3% of the girls versus 4.8% of the boys.     

Together towards Life

Which are the convincing ways of evangelism in the secular, multicultural countries of western Europe? Does the new mission affirmation Together towards Life offer relevant contributions to this debate? This article explores recent developments in western Europe. It starts by reviewing the secular nature of these countries and then explains how migration has tested the secularization thesis. The transformation of western European cultures from secular toward secular/multi‐religious reopens the debate on secularism and religion. The article also reflects on the question of what the central ideas in the new mission affirmation – the affirmation of life, the power of the Holy Spirit, mission from the margins, and authentic evangelism as discipleship – may mean in these changing secular cultures. The author concludes that discipleship, provided it is authentic, may help to move beyond the apparent contradictions between secularism and religion and may help to find new ways of bringing forth the good news.
