The Effect of an Occupational Therapy Role-Playing Intervention on the Social Skills of Adolescents With Asperger's Syndrome: A Pilot Study

The purpose of the authors in this pilot study was to assess the effects of an occupational therapy role-playing intervention for adolescents with Asperger's syndrome. An ABA multiple baseline single-subject design across participants was used with three adolescents to determine if a six-week intervention could increase targeted social behaviors. Data were collected over baseline, intervention, and probe phases. Three methods of analysis were used: visual inspection of graphed data, paired t tests, and a three standard deviation-band approach. Findings demonstrated that all three participants were able to increase the frequency of targeted social skill use from baseline to intervention and maintain this level at a one month probe. Differences between baseline and intervention phases for each participant reached statistical significance. Through this study the authors offer preliminary evidence that an occupational therapy role-playing intervention that is both client centered and graded can increase targeted social skill use in three adolescents with Asperger's syndrome.     

Does group identification facilitate or prevent collective guilt about past misdeeds? Resolving the paradox

The influence of group identification on collective guilt and attitudes towards reparation was examined in the context of the Belgian colonization of Congo. People should experience collective emotions to the extent that being a member of the relevant group is part of their self-concept. Yet, the acknowledgement of ingroup responsibility for past misdeeds is particularly threatening for high identifiers and may lead to defensive reactions aimed at avoiding guilt. We therefore predicted, and found, a curvilinear effect of identification on collective guilt. Attitudes towards reparation of past wrongdoings were also assessed and yielded a linear trend: identification predicted less favourable attitudes towards reparation but this effect was marginally stronger as identification increased.     

New variations of intrahemispheric and interhemispheric processing indexed by the dimond paradigm

We report 2 experiments designed to demonstrate that unilateral tachistoscopic stimulation would yield a response time (RT) advantage over bilateral stimulation in a simple experiment, whereas the opposite pattern would occur in a complex version of the same task, as predicted by the intrahemispheric resource limitation model of Banich and colleagues. Experiment 1 was a go/no-go task in which participants had to press a key when two shapes (circles or squares) were identical on the computer screen. A unilateral field advantage was obtained that was accentuated in several task conditions that yielded overall longer RTs, mostly in the bilateral condition. Experiment 2 was similar but required a more complex judgment: The go trials were to 2 stimuli identical on 1 dimension (shape or color) but not both or neither. The RTs were significantly and substantially longer than in Experiment 1 and exhibited a nonsignificant bilateral field advantage, which differed significantly from the unilateral field advantage obtained in Experiment 1. These results support the intrahemispheric resource limitation model of Banich and colleagues. However, several within-experiment effects are in direct opposition to this model and are best explained as limitations of commissural relay of perceptual information.     

Context-dependent activation of reduced autobiographical memory specificity as an avoidant coping style

According to the affect-regulation hypothesis (Williams et al., 2007), reduced autobiographical memory specificity (rAMS) or overgeneral memory (OGM) might be considered a cognitive avoidance strategy; that is, people learn to avoid the emotionally painful consequences associated with the retrieval of specific negative memories. Based on this hypothesis, one would predict significant negative associations between AMS and avoidant coping. However, studies investigating this prediction have led to equivocal results. In the present study we tested a possible explanation for these contradictory findings. It was hypothesized that rAMS (in part) reflects an avoidant coping strategy, which might only become apparent under certain conditions, that is, conditions that signal the possibility of 'danger.' To test this hypothesis, we assessed AMS and behavioral avoidance but experimentally manipulated the instructions. In the neutral condition, two parallel versions of the Autobiographical Memory Test (AMT) were presented under neutral instructions. In the threat condition, the first AMT was presented under neutral instructions, while the second AMT was presented under 'threat instructions.' Results showed no significant correlations between avoidance and OGM under neutral conditions but significant and markedly stronger correlations under threat conditions, with more avoidance being associated with fewer specific and more categoric memories. In addition, high avoiders showed a stronger reduction in AMS in the threat condition as compared with the neutral condition, while low avoiders showed no such difference between conditions. The data confirm that OGM can be considered as part of a broader avoidant coping style. However, more importantly, they show that, at least in nonclinical individuals, the activation of this coping style may depend on the context.     

Now you see it … and now again: Semantic interference reflects lexical competition in speech production with and without articulation

Semantic interference effects in the picture—word interference (PWI) paradigm have long been assumed to reflect competitive mechanisms during lexical selection, a core component of the speech production system. However, recent observations of facilitative effects have cast doubt on the usefulness of the paradigm for investigating lexicalization, and on the existence of lexical competition in general. An alternative proposal suggests that lexical selection is not by competition, and that interference effects reflect articulatory processes outside the lexical system. Here, we contrast these theoretical alternatives with semantic distractor effects in the PWI paradigm. In two tasks, pictures were either overtly named or the names were manually classified. Interference effects of comparable magnitude were observed in both response modalities, regardless of whether the names were articulated or not. This finding supports lexical competition models and suggests that the articulators are not the source of interference in the PWI paradigm.

Counterconditioning reduces cue-induced craving and actual cue-elicited consumption

Cue-induced craving is not easily reduced by an extinction or exposure procedure and may constitute an important route toward relapse in addictive behavior after treatment. In the present study, we investigated the effectiveness of counterconditioning as an alternative procedure to reduce cue-induced craving, in a nonclinical population. We found that a cue, initially paired with chocolate consumption, did not cease to elicit craving for chocolate after extinction (repeated presentation of the cue without chocolate consumption), but did so after counterconditioning (repeated pairing of the cue with consumption of a highly disliked liquid, Polysorbate 20). This effect persisted after 1 week. Counterconditioning moreover was more effective than extinction in disrupting reported expectancy to get to eat chocolate, and also appeared to be more effective in reducing actual cue-elicited chocolate consumption. These results suggest that counterconditioning may be more promising than cue exposure for the prevention of relapse in addictive behavior.     

Brooding and Reflection as Subtypes of Rumination: Evidence from Confirmatory Factor Analysis in Nonclinical Samples using the Dutch Ruminative Response Scale

Previous research has shown that depressive rumination is an important vulnerability factor for experiencing depressive symptoms. The most widely used measure to assess depressive rumination is the Ruminative Response Scale (RRS). According to Treynor et al. (Cognitive Therapy and Research 27:247–259, 2003), the RRS contains two subscales, reflecting two different rumination subcomponents: brooding and reflection. The present study examined the psychometric properties of the RRS in two samples (N = 432 and N = 407). Based on a confirmatory factor analysis (CFA), results confirmed that a two-dimensional model with brooding and reflection factors provided an adequate fit to the data. Reliability, convergent and discriminant validity of the rumination subcomponents were appropriate. Furthermore, brooding but not reflection predicted depressive symptoms prospectively, even when accounting for concurrent depressive feelings. The results provide the first confirmatory factor-analytical support for the widely assumed two-factor model of the RRS and add to the accumulating body of evidence supporting the multidimensional nature of depressive rumination.
