Modality effects: Do they fall on deaf ears?

The present study tests the assumption of the PAS theory of echoic memory (Greene & Crowder, 1984) that the representation of acoustic features is necessary in producing modality effects. Performance by deaf subjects was compared to hearing subjects on serial and free-recall tasks with vocalizing and non-vocalizing conditions. For the serial tasks, typical modality and acoustic similarity effects were observed with hearing subjects, and no such effects were found with deaf subjects. However, for the free-recall task, modality effects were found for both deaf and hearing subjects. It is unlikely that phonological coding resulting from gestural cues mediates the modality effect, as phonological confusion errors for deaf and hearing subjects did not correlate with the size of this effect.     

Combining Action Observation and Motor Imagery Improves Eye–Hand Coordination during Novel Visuomotor Task Performance

Abstract

In this study, we compared the effectiveness of concurrent action observation and motor imagery (AO?+?MI), observing with the intent to imitate (active observation; AO), and passive observation (PO) training interventions for improving eye–hand coordination. Fifty participants were assigned to five groups [AO?+?MI, AO, PO, physical practice (PP); control] and performed a visuomotor rotation task, whilst eye movements were recorded. Each participant then performed 20 task trials in a training intervention before repeating the visuomotor rotation task in a post-test. As expected, PP produced the greatest improvement in task performance and eye–hand coordination. However, in comparison to the control group, AO?+?MI training produced a statistically significant increase in both task performance and eye–hand coordination, but no such improvements were found following AO or PO.     

Research on Teaching the Psychology of Women

Research into the impact of psychology of women courses (and women's studies, generally) has been conducted only infrequently. The literature consists largely of anecdotal reports of changes in attitudes toward women as a function of participating in such courses. Existing quantitative studies are usually limited to measures of pre-course to post-course attitude changes, and occasionally such changes are related to demographic factors. The purpose of this article is to review current studies and to suggest additional research approaches in this area. At least three methods are recommended for studying the effect of psychology of women courses. First, there is a need for comparative studies of two types: psychology of women course vs. other course comparisons, and psychology of women course vs. other related experiences (consciousness-raising groups, feminist therapy, etc.). Second, there is a need for follow-up assessment of students in these courses. Finally, in both the comparative and follow-up studies, behavioral measures should be used.     

On precipitating factors: cancer as a cause of suicide

This case-control study provides individual-based data describing the impact of being a cancer patient on the odds of suicide. 5,009 suicides and 17,064 controls are compared. The data indicate that cancer patients are 50 to 100 percent more likely than nonpatients to commit suicide. This and other studies indicate that health status should be considered in future attempts to relate suicide to social environment.
