Visual perception in fencing: Do the eye movements of fencers represent their information pickup?

The present study examined whether results of athletes' eye movements while they observe fencing attacks reflect their actual information pickup by comparing these results with others gained with temporal and spatial occlusion and cuing techniques. Fifteen top-ranking expert fencers, 15 advanced fencers, and 32 sport students predicted the target region of 405 fencing attacks on a computer monitor. Results of eye movement recordings showed a stronger foveal fixation on the opponent's trunk and weapon in the two fencer groups. Top-ranking expert fencers fixated particularly on the upper trunk. This matched their performance decrements in the spatial occlusion condition. However, when the upper trunk was occluded, participants also shifted eye movements to neighboring body regions. Adding cues to the video material had no positive effects on prediction performance. We conclude that gaze behavior does not necessarily represent information pickup, but that studies applying the spatial occlusion paradigm should also register eye movements to avoid underestimating the information contributed by occluded regions.     

Ideal selves and self‐esteem in people with independent or interdependent self‐construal

Not living up to one's ideal self has been shown to coincide with decreased self‐esteem. In the present paper, this notion is applied to the differentiation between people with independent versus interdependent self‐construal. We suggest that the ideal self of independents differs in two respects from the one of interdependents: with respect to its contents (autonomous versus social self‐knowledge) and with respect to the degree of context‐dependency of the encoded knowledge (context‐independent versus context‐dependent self‐knowledge). In three studies, via a priming we either manipulated contents or degree of context‐dependency of what participants considered themselves to actually be like. On both explicit and implicit measures, participants with independent construal indicated higher self‐esteem after priming of autonomous and context‐independent knowledge than after priming of social and context‐dependent knowledge. The opposite pattern was observed in participants with interdependent construal. Results suggest that independent and interdependent construals mirror different ideals which are applied as a comparison standard when evaluating the self.

A CRITIQUE OF BOROWITZ'S POSTMODERN JEWISH THEOLOGY

Abstract. Borowitz's book is primarily a systematic response by a liberal Jewish theologian to his perceived challenges from rationalism on one hand and postmodernism on the other. It is within this context that Borowitz discusses issues of the relationship between modern science and Judaism. The first part of this essay is a summary of Borowitz's book. Here I locate Borowitz's place in the general discipline of Jewish philosophy and theology. The second part of the paper is a critique of Borowitz's discussion of postmodernism and liberalism. It is in this concluding section that the issues raised by contemporary science for Jewish religious thought are discussed.     

Searching for the functional locus of the SNARC effect: Evidence for a response-related origin

Dehaene, Bossini, and Giraux (1993) showed that when participants make parity judgments, responses to numerically small numbers are made faster with the left hand, whereas responses to large numbers are made faster with the right hand (the SNARC [spatial-numerical association of response codes] effect). According to one view, the SNARC effect arises at an early processing stage due to (in)congruencies between the digit's side of presentation and its representation on the mental number line, independently of response effector(s). Alternatively, the SNARC effect might arise at a later response-related stage due to (in)congruencies between the digit's representation on the mental number line and the side of response, independently of the side of presentation. The results of three experiments, using central and lateralized stimuli, and vocal and manual responses, clearly support the view that the SNARC effect arises at a relatively late response-related stage, without substantive contributions from earlier processing stages.
