An examination of the relationship between visual capture and prism adaptation

The phenomena of prismatically induced “visual capture” and adaptation of the hand were compared. In Experiment 1, it was demonstrated that when the subject’s hand was transported for him by the experimenter (passive movement) immediately preceding the measure of visual capture, the magnitude of the immediate shift in felt limb position (visual capture) was enhanced relative to when the subject moved the hand himself (active movement). In Experiment 2, where the dependent measure was adaptation of the prism-exposed hand, the opposite effect was produced by the active/passive manipulation. It appears, then, that different processes operate to produce visual capture and adaptation. It was speculated that visual capture represents an immediate weighting of visual over proprioceptive input as a result of the greater precision of vision and/or the subject’s tendency to direct his attention more heavily to this modality. In contrast, prism adaptation is probably a recalibration of felt limb position in the direction of vision, induced by the presence of a registered discordance between visual and proprioceptive inputs.     

A Wittgensteinian View of Mind and Self-Knowledge

Philosophia - This paper defends a Wittgenstein-inspired conception of the nature of mind and self-knowledge. Thus, it is claimed that the mind is to be conceived as expressive behaviour; and that...     

Learning spatial dimensions with a visual sensory aid: Molyneux revisited

The relationship between sensory aid research and several areas of perceptual learning has been explored with five experiments on learning the use of the Binaural Sensory Aid, an electronic sensor in which pitch specifies distance and interaural amplitude difference (IAD) specifies direction. The training task required reaching to objects in near space, with tactile error feedback. Perceptual learning for both dimensions was demonstrated within 72 trials, giving a level of performance comparable to the use of a natural sound source, although performance with the direction cue did not reach asymptote until a second training session. Training was unaffected by various kinds of regularity in the spatial target sequences, or by a reduction in the number of spatial target locations until only two locations were used; at this point directional accuracy declines. Training only one dimension at a time did not produce additional improvement of performance on that dimension, but did impair generalization of the direction cue. Learning of the pitch-distance dimension was generally better than that of the IAD dimension, possibly because of its greater discriminability with this device. Generally, the pattern of results indicates that in learning to use such devices subjects readily determine the sensory dimensions of the codes and have considerable ability to generalize to new locations.     

Temporal discrimination of recycled tonal sequences: Pattern matching and naming of order by untrained listeners

Sets of recycled sequences of four successive tones were presented in all six possible orders to untrained listeners. For pitches within the musical range, recognition (as measured by matching of any unknown order with an array of permuted orders of the same tones) could be accomplished as readily for tonal durations and frequency separations outside the limits employed for melodic construction as inside these limits. Identifying or naming of relative pitches of successive tones was considerably more difficult than matching for these tonal sequences, and appeared to follow different rules based upon duration and upon frequency separation. Use of frequencies above the pitch limits for music (4,500 Hz and above) resulted in poor performance both for matching and naming of order. Introduction of short silent intervals between items was without effect for both tasks. Naming of order and pattern recognition appear to reflect different basic processes, in agreement with earlier formulations based on experiments with phonemic sequences of speech and sequences of unrelated sounds (hisses, tones, buzzes). Special characteristics of tonal sequences are discussed, and some speculations concerning music are offered.     

Tolerance towards dating violence in Spanish adolescents

The study of intimate partner violence among adolescent and young couples in Spain remains unattended, although such abuses are well known and more frequent than in adulthood. The aim of this study is, on the one hand, to provide epidemiological information on dating relationships, and on the other hand, to identify attitudes towards violence. 2205 women enrolled in schools in diverse provinces of Spain, participated in the study. Average age was near 19 years (SD= 2.25). The Dating Violence Questionnaire (DVQ, in Spanish, CUVINO), a questionnaire that assesses both frequency and distress associated with violent behavior, was used. The DVQ allowed differentiating between groups of women self-labeled as abused and not abused on the basis of the frequency of sustained violence, although the levels of distress in the face of violence were statistically similar in both groups. Implications for future research and prevention programs are discussed.     

Development of abbreviated nine-item forms of the Raven's standard progressive matrices test

The Raven's standard progressive matrices (RSPM) is a 60-item test for measuring abstract reasoning, considered a nonverbal estimate of fluid intelligence, and often included in clinical assessment batteries and research on patients with cognitive deficits. The goal was to develop and apply a predictive model approach to reduce the number of items necessary to yield a score equivalent to that derived from the full scale. The approach is based on a Poisson predictive model. A parsimonious subset of items that accurately predicts the total score was sought, as was a second nonoverlapping alternate form for repeated administrations. A split sample was used for model fitting and validation, with cross-validation to verify results. Using nine RSPM items as predictors, correlations of .9836 and .9782 were achieved for the reduced forms and .9063 and .8978 for the validation data. Thus, a 9-item subset of RSPM predicts the total score for the 60-item scale with good accuracy. A comparison of psychometric properties between 9-item forms, a published 30-item form, and the 60-item set is presented. The two 9-item forms provide a 75% administration time savings compared with the 30-item form, while achieving similar item- and test-level characteristics and equal correlations to 60-item based scores.
