Duration estimation and the phonological loop: Articulatory suppression and irrelevant sounds

Clock-based theories of time estimation propose that clock pulses are accumulated in working memory. Although these theories do not constrain the form of the memory trace, evidence reported in the literature suggests that active manipulation of a verbal trace may be involved. Four experiments are reported in which participants reproduced or verbally estimated short durations (up to a few seconds) either in a single-task condition or in a condition with a phonological load. Experiments 1, 2 and 4 showed that both interval reproduction and verbal estimation were impaired under concurrent articulatory suppression in comparison to a timing only control condition. Neither irrelevant speech (Experiments 1-3) nor irrelevant tones and music (Experiment 3) impaired timing performance. These findings are taken to show that time estimation is mediated by phonological working memory and the involvement of an active articulatory rehearsal process.     

Women at Midlife: Spiritual Maturity and Life Satisfaction

This study examined the relationship between spiritual maturity and life satisfaction in a multi-ethnic, religiously diverse sample of women middle aged and older. Spiritual maturity was measured by the spiritual support and spiritual openness subscales of the Revised Spiritual Experience Index. Life-satisfaction was positively related to spiritual support and spiritual openness. European Americans and African Americans did not differ on life-satisfaction, spiritual support, or spiritual openness. Mean splits on the spiritual-support and spiritual-openness scales were used to classify subjects as underdeveloped, dogmatic, transitional, and growth-oriented. Growth-oriented subjects reported greater life-satisfaction than subjects in all other groups. No other group differences were found.     

How depressing: Another cognitive dimension of commonsense knowledge

Subjects in three naturally-occurring groups were asked to rate 15 events, mentioned by Ss in a previous study, as amongst those which would make them feel worse if they were already feeling depressed, according to how depressed each event would be likely to make them feel. They were also asked to estimate the mean rating that their group would give each item. High, positive and significant correlations were found between the two sets of mean ratings in all three groups and the mean predictions for all groups were also significantly correlated. The findings suggested that people in our culture possess generally accurate, socially-shared ideas about the likely impact of such events on depressed others. Qualitative data suggested that their ideas are associated with qualifications about factors which modulate the impact of these events. The results are discussed in the light of recent research on the social behaviour of depressives and of the neoclassical tradition of advice on melancholy.     

Practice with anxiety improves performance,but only when anxious: evidence for the specificity of practice hypothesis

We investigated for the first time whether the principles of specificity could be extended to the psychological construct of anxiety and whether any benefits of practicing with anxiety are dependent on the amount of exposure and timing of that exposure in relation to where in learning the exposure occurs. In Experiment 1, novices practiced a discrete golf-putting task in one of four groups: all practice trials under anxiety (anxiety), non-anxiety (control), or a combination of these two (i.e., the first half of practice under anxiety before changing to non-anxiety conditions, anxiety-control, or the reverse of this, control-anxiety). Following acquisition, all groups were transferred to an anxiety condition. Results revealed a significant acquisition-to-transfer decrement in performance between acquisition and transfer for the control group only. In Experiment 2, novices practiced a complex rock climbing task in one of the four groups detailed above, before being transferred to both a high-anxiety condition and a low-anxiety condition (the ordering of these was counterbalanced across participants). Performance in anxiety transfer was greater following practice with anxiety compared to practice without anxiety. However, these benefits were influenced by the timing of anxiety exposure since performance was greatest when exposure to anxiety occurred in the latter half of acquisition. In the low-anxiety transfer test, performance was lowest for those who had practiced with anxiety only, thus providing support for the specificity of practice hypothesis. Results demonstrate that the specificity of learning principle can be extended to include the psychological construct of anxiety. Furthermore, the specificity advantage appears dependent on its timing in the learning process.     

AN INVESTIGATION OF THE DIFFERENCE DEFICIT HYPOTHESIS USING THE CLOZE PROCEDURE

Abstract

This study considers the hypothesized differences of difference and deficitreaders using the cloze procedure in narrative passages at the fourth grade level. The authors reject the hypothesis that deficit readers are better able to use surrounding context than difference readers. While the study's experimental design to test the difference/deficit hypothesis may not be the most powerful, it is a modified replication of a previous study from which the difference/deficit hypothesis was drawn (Cromer & Weiner, 1966). As such it does not seem to support difference/deficit notions of reading disability.
