Depression, self-esteem, and complex attributions for life problems

Past research has suggested that mild and moderate depression are associated with increased attributional processing and a tendency to make complex attributions involving two or more causes. The present research tested the hypothesis that depression and low self-esteem are associated with a tendency to make attributions to multiple causes when faced with life problems. The results were used to demonstrate that the tendency to make multiple attributions for specific life problems accounts for unique variance in depression and self-esteem scores, even after removing variance due to general attributional style. The findings are discussed with reference to the need for multidimensional models of attribution in depression and attributional retraining efforts to include an emphasis on individual differences in the number of multiple attributions made by people.     

The effects of prohibiting gestures on children's lexical retrieval ability

Two alternative accounts have been proposed to explain the role of gestures in thinking and speaking. The Information Packaging Hypothesis (Kita, 2000) claims that gestures are important for the conceptual packaging of information before it is coded into a linguistic form for speech. The Lexical Retrieval Hypothesis (Rauscher, Krauss & Chen, 1996) sees gestures as functioning more at the level of speech production in helping the speaker to find the right words. The latter hypothesis has not been fully explored with children. In this study children were given a naming task under conditions that allowed and restricted gestures. Children named more words correctly and resolved more 'tip-of-the-tongue' states when allowed to gesture than when not, suggesting that gestures facilitate access to the lexicon in children and are important for speech production as well as conceptualization.     

The Experiential Liberation Strategy of the Existential-Integrative Model of Therapy

This article summarizes the experiential liberation strategy of the existential-integrative (EI) model of therapy. The existential-integrative model of therapy provides one way to understand and coordinate a variety of intervention modes within an overarching ontological or experiential context. I will (1) define the experiential liberation strategy—such as its emphasis on the capacities to constrict, expand, and center psychophysiological capacities; (2) describe its salient features—such as the four stances that promote experiential liberation: presence, invoking the actual, vivifying and confronting resistance, and the cultivation of meaning and awe; and (3) illustrate the relevance of the strategy to case vignettes drawn from actual practice.

Training effects on dual-task performance: are there age-related differences in plasticity of attentional control?

A number of studies have suggested that attentional control skills required to perform 2 tasks concurrently become impaired with age (A. A. Hartley, 1992; J. M. McDowd & R. J. Shaw, 2000). A. A. Hartley (2001) recently observed that the age-related differences in dual-task performance were larger when the 2 tasks required similar motor responses. The present study examined the extent to which age-related deficits in dual-task performance or time sharing--in particular, dual-task performance of 2 discrimination tasks with similar motor requirements--can be moderated by training. The results indicate that, even when the 2 tasks required similar motor responses, both older and younger adults could learn to perform the tasks faster and more accurately. Moreover, the improvement in performance generalized to new task combinations involving new stimuli. Therefore, it appears that training can substantially improve dual-task processing skills in older adults.     

Volition and the idle cortex: beta oscillatory activity preceding planned and spontaneous movement

Prior to the initiation of spontaneous movement, evoked potentials can be seen to precede awareness of the impending movement by several hundreds of milliseconds, meaning that this recorded neural activity is the result of unconscious processing. This study investigates the neural representations of impending movement with and without awareness. Specifically, the relationship between awareness and 'idling' cortical oscillations in the beta range (18-24Hz) was assessed. It was found that, in situations where there was awareness of the impending movement, pre-movement evoked potentials were associated with a decrease in beta range oscillations. In contrast, when awareness of the impending movement was not present, the onset of the pre-movement potential was associated with tonic levels of beta range oscillations. A model is considered where by distributed neural activity remains outside of conscious awareness through the persistence of tonic slow wave cortical oscillations.
