Comparison of two indicators of perceived egocentric distance under full-cue and reduced-cue conditions.
It has not been established that walking without vision to previewed targets is indeed controlled by perceived distance. To this end, we compared walking and verbal report as distance indicators, looking for a tight covariation in responses that would indicate control by a common variable. Targets from 79-500 cm away were presented under dark and well-lit conditions. Both verbal reports and wal...
متن کاملEffects of signal features and background noise on distance cue discrimination by a songbird.
During the transmission of acoustic signals, the spectral and temporal properties of the original signal are degraded, and with increasing distance more and more echo patterns are imposed. It is well known that these physical alterations provide useful cues to assess the distance of a sound source. Previous studies in birds have shown that birds employ the degree of degradation of a signal to e...
متن کاملDiscrimination in a General Algebraic Setting
Discriminating groups were introduced by G. Baumslag, A. Myasnikov, and V. Remeslennikov as an outgrowth of their theory of algebraic geometry over groups. Algebraic geometry over groups became the main method of attack on the solution of the celebrated Tarski conjectures. In this paper we explore the notion of discrimination in a general universal algebra context. As an application we provide ...
متن کاملDistance discrimination in frontopolar rats.
Lmnand 1(5) has shown that in the rat the portion of the cortex occupying the frontal pole, which was considered for a long time as a homologue of the frontal association cortex d higher mammals, does not receive projection from the mledidorsal thalamic nucleus. Thus, this region does not fulfil the accepted criterion for the pr8efrontal cortex. It seems now that the frontopolm cortex d rat res...
متن کاملThe cue for contour-curvature discrimination.
Seven potential geometric cues for contour-curvature discrimination were tested: curvature, turning-angle, arc-length, arc-length-divided-by-chord-length, maximum-deviation (sag), mean-deviation and area. Three experiments were performed, each requiring the discrimination of two simultaneously presented, 1-sec-duration, curved-line stimuli, whose chord-lengths ranged from 12 to 48 arcmin visual...
