Indirect interception actions by blind and sighted perceivers: The role of modality and tau

Vernat, J.‐P. & Gordon, M.S. (2011). Indirect interception actions by blind and sighted perceivers: The role of modality and tau. Scandinavian Journal of Psychology 52, 83–92. Acoustic and visual interceptive actions were tested in this research by comparing the performance of blind, blind‐folded, and sighted individuals. An indirect interception method was employed in which the participant had to roll an intercepting ball towards a moving target on a perpendicular track. The interception task used conditions that varied the speed, rolling distance, and target size/intensity. While performance was highly consistent and accurate for visual participants in this research, the blind and blind‐folded participants demonstrated much more performance variability in response to changes in speed and distance. Manipulation of target size and intensity did not affect judgments, however performance tended to be more accurate at shorter distances and with faster target speeds. Results from this research are discussed in terms of their implications for tau in acoustic interception, and the use of spatial and temporal cues for guiding interceptive actions.     

EFFECTS OF UNANTICIPATED SELF-DISCLOSURE ON RECIPIENTS OF VARYING LEVELS OF SELF-ESTEEM: A RESEARCH NOTE

Assuming that another's self-disclosure can be rewarding, it was hypothesized that attraction for one who disclosed a relatively high amount of personal information would be greater than attraction for a low discloser when the disclosure was perceived as being appropriate. Also, it was hypothesized that persons of high self-esteem may be more attracted to a high discloser than persons of moderate or low self-esteem. An experiment examined the effects of a confederate's self-disclosure (high or low degree of personal content) on a recipient. Greater attraction was demonstrated toward the confederate in the low disclosure condition, and her behavior was perceived to be more appropriate in this condition. Persons who participated in each of the experimental conditions were divided into three self-esteem categories. Those with intermediate levels of self-esteem were found to be the most receptive to a disclosing other, followed by subjects of low, and finally high self-esteem.
