Attending to a misoriented word causes the eyeball to rotate in the head

Torsional eye movements are triggered by head tilt and a rotating visual field. We examined whether attention to a misoriented form could also induce torsion. Thirty-six observers viewed an adapting field containing a bright vertical Une, and then they viewed a display that was composed of two misoriented words (one rotated clockwise, the other counterclockwise, by 15°, 30°, or 45°). The subjects were instructed to attend to one of the words. The subjects’ adjustments of a reference line to match the tilt of the afterimage showed that attention to a misoriented word produces torsional eye movement (verified with direct measurements on 4 additional subjects). This eye movement reduces the retinal misorientation of the word by about 1°. The results of this study reinforce the linkage between selective attention and eye movements and may provide a useful tool for dissecting different forms of “mental rotation” and other adjustments in internal reference frames.

Joint action: bodies and minds moving together

The ability to coordinate our actions with those of others is crucial for our success as individuals and as a species. Progress in understanding the cognitive and neural processes involved in joint action has been slow and sparse, because cognitive neuroscientists have predominantly studied individual minds and brains in isolation. However, in recent years, major advances have been made by investigating perception and action in social context. In this article we outline how studies on joint attention, action observation, task sharing, action coordination and agency contribute to the understanding of the cognitive and neural processes supporting joint action. Several mechanisms are proposed that allow individuals to share representations, to predict actions, and to integrate predicted effects of own and others' actions.

Effects of Emotional Factors Upon Recall

Bendig's (1) Pittsburgh Scales of Social Extraversion-Introversion (SEI) and Emotionality (Em) were translated so that they were of appropriate reading difficulty for children as well as for adults. The revised scales correlated highly (both .90) with the Pittsburgh scales, and they had high test-retest reliabilities (.92 and .89). Data from samples representing third grade to college ages were presented for the revised scales. SEI-Em correlations were nonsignificant for most subsamples, indicating that the revised SEI-Em scales are independent. Scale means were stable across ages. The revised scales should be considered as research instruments, since more representative normative data and validity data are still required. The scales should, though, facilitate developmental research in extraversion and emotionality.
