Experimental Evaluation of Near‐ and Far‐Transfer Effects of an Adaptive Multicomponent Working Memory Training

An important question in cognitive science today is whether working memory training leads to transfer effects. Training studies reported no transfer as well as far transfer to untrained abilities (e.g., reasoning), but different methodological problems have not allowed reliable conclusions to be drawn. Furthermore, most samples have consisted of young adults, whereas older adults have rarely been included. This study attempted to address these limitations. Ninety‐one older adults were randomly assigned to a training group or an active or passive control group. Short‐term memory, speed, and reasoning were assessed as far‐transfer criteria. In addition, transfer to everyday life was investigated using an ambulatory assessment method. Although there were significant training effects, no transfer effects were found. Instead, the active control group showed the same increase in the near‐transfer tasks (i.e., working memory) as the experimental group indicating that unspecific factors explain the training gains of older adults.

Impulsive for life? The nature of long-term impulsivity in domestic dogs

Individual differences in impulsivity occur at a cognitive and/or behavioural level and are associated with differing life outcomes. However, there is a lack of empirical evidence to support the long-term stability of these characteristics in non-human animals. This study reports on the stability of convergent measures of impulsivity in domestic dogs assessed more than 6 years apart. Measures were (1) owner assessment by means of a questionnaire, the validated ‘Dog Impulsivity Assessment Scale’ (DIAS) and (2) dogs’ performance in a delayed reward choice test. Dogs had 15-min free access to two food dispensers, one dispensing a piece of food immediately, the other dispensing three pieces after a delay, which increased by 1 s every other time the dogs sampled it. Maximum delay reached in this task reflects decision-making, or cognitive impulsivity, whereas the rate of extra presses on the delayed reward device during the delay can be considered as a measure of motor or behavioural impulsivity. DIAS scores were strongly and significantly correlated across years. The maximum delay reached in the behaviour test was also highly stable, whereas paw-pressing rate was uncorrelated between the years. These results demonstrate that cognitive but not motor impulsivity is highly consistent over time in dogs.     

Prognostische Validität des Level of Service Inventory-Revised

This study examined the validity of the level of service inventory-revised (LSI-R) for a sample of young violent offenders in Germany (N?=199) who were sentenced to more than 2 years imprisonment using a retrospective study design. Offenders with a migrant background from a predominantly Muslim country were compared to native German offenders. Both groups were similar regarding age, criminal history, socioeconomic status, education, current risk of subsequent offending and recidivism. For the group of young offenders with a migrant background from a predominantly Muslim country (n?=85), the LSI-R failed to validly predict problem behavior during imprisonment as well as to validly predict recidivism within 2 and 5 years after release from prison. In contrast, for native German offenders (n?=114) the LSI-R performed satisfactorily in predicting problematic behavior during imprisonment and achieved a moderate to high level of predictive power in predicting recidivism after release from prison. These findings stress the necessity for research on influencing factors, developmental dynamics and prognosis among young violent offenders with a migrant background from a predominantly Muslim culture.     

The One-Sidedness of a Dialogue Between Neuroscience and Psychoanalysis

This discussant’s view is that neuroscience would be unable to provide data relevant to human experience without input from human minds, but the theory and practice of psychoanalysis, as yet, have little to learn from neuroscience in spite of extensive and fascinating neurobiological research. Gerson’s evident knowledge of that research is much appreciated.     

Mental context reinstatement or drawing: Which better enhances children's recall of witnessed events and protects against suggestive questions?

The aim of this experiment was to examine the effectiveness of two techniques in enhancing children's recall of an event that they experienced approximately a week earlier. Younger (5–6 years) and older (8–9 years) children were interviewed about a magic show event in one of three conditions. Before recalling the event, some children were instructed to mentally reinstate the context of the event (MCR group), others were asked to draw the context of the event (DCR group), and others received no reinstatement instructions (NCR). Results showed that these instructions had no impact on children's free recall or responses to open‐ended prompts. However, reinstatement instructions impacted children's responses to suggestive questions: those in the DCR group gave more accurate responses than those in the NCR group. These findings provide preliminary support for the use of drawing as a potentially protective exercise that lessens the impact of biased questions with child witnesses.     

The Effect of Intuitive Advice Justification on Advice Taking

How do you respond when receiving advice from somebody with the argumentation “my gut tells me so” or “this is what my intuition says”? Most likely, you would find this justification insufficient and disregard the advice. Are there also situations where people do appreciate such intuitive advice and change their opinion accordingly? A growing number of authors write about the power of intuition in solving problems, showing that intuitively made decisions can be of higher quality than decisions based on analytical reasoning. We want to know if decision makers, when receiving advice based on an intuitive cognitive process, also recognize the value of such advice. Is advice justified by intuition necessarily followed to a lesser extent than an advice justified by analysis? Furthermore, what are the important factors influencing the effect of intuitive justification on advice taking? Participants across three studies show that utilization of intuitive advice varies depending on advisor seniority and type of task for which the advice is given. Summarizing, the results suggest that decision makers a priori doubt the value of intuitive advice and only assess it as accurate if other cues in the advice setting corroborate this. Intuitively justified advice is utilized more if it comes from a senior advisor. In decision tasks with experiential products, intuitively justified advice can even have more impact than analytically justified advice. Copyright © 2013 John Wiley & Sons, Ltd.     

Emotions in Advice Taking: The Roles of Agency and Valence

Recently, advice taking has received attention in decision‐making research, and some studies suggest that emotions may play a role in this process. Yet a clear account of how emotions influence advice taking is lacking. The current research introduces a parsimonious explanation by suggesting that such effects can be predicted on the basis of two emotion dimensions: valence (positivity or negativity) and agency (self‐focused versus other‐focused). In five experiments with different emotion inductions and different measures for advice taking, the effects of positive emotions such as gratitude and pride and of negative emotions such as anger and shame on advice taking were studied. The findings reveal that emotion valence and agency exert an influence on advice taking and that this interaction effect is mediated by the perceived ability of the advisor. Together, these findings provide a unique theoretical and empirical contribution to our understanding of emotions in advice taking. Copyright © 2013 John Wiley & Sons, Ltd.     

Self- and social perception of physical appearance in chest wall deformity

This study analyzes self- and social perception of physical appearance in patients with chest wall deformity (CWD), including both pectus carinatum and pectus excavatum. Self-perception of appearance in 76 patients with CWD and social perception of patients' appearance by 20 adult and 20 adolescent raters was assessed using the Appearance Rating Scale (Stangier et al., 2000) and evaluated for agreement and multivariate correlates. Results indicate no agreement between self- and social rating. Based on mean scores patients rated their appearance significantly more negatively than adult raters but only slightly different than adolescent raters. Adolescent raters' judgment of the patients' appearance was related to CWD characteristics, while self-rating rather seems to be related to psychosocial factors. Because adolescents are a relevant peer group for adolescent patients with CWD their evaluation of the appearance might influence patients' self-image and might affect their psychological functioning. Effective interventions focusing on social interactions are needed.
