摘要:

Eleven rats were reared in a cage with moving figures. Eleven litter mates were reared in a similar cage but without figures. The rats from the more complex environment showed less locomotor activity in a checkerboard maze and, in a two‐lever test box, higher preference for the lever which produced complex visual stimuli. It is proposed that rearing in stimulus poverty increases locomotor activity and reduces curiosit

摘要:

Experiments with projected negative afterimages and with the aftereffects of a rotating spiral were performed serially (repeated stimulus presentation). In the middle of the sequences the experimental groups were subjected to subliminal threat by means of a metacontrast technique. The effects of threat on the latter part of the sequences were according to predictions and differed markedly from the results in control groups.

摘要:

When a word perception task was studied under conditions of binocular rivalry, the meaningful one of two rivalling strings of letters was identified more often than the other. Differences in frequency of the trigrams in the Norwegian language had no effect.

摘要:

Recent studies of cross‐modal matching and transfer in animals and human subjects are reviewed and some problems concerning the design of experiments to study these phenomena discussed. Attempts to account for cross‐modal effects are evaluated and the concept of sensory equivalence briefly exami

摘要:

By analogy with Stavrianos' (1945) finding for linear perspective, it was proposed that the effectiveness of foreshortening as a slant cue would increase as a function of visual angle. Surfaces of vertical lines slanted around a vertical axis were monocularly viewed at three horizontal visual angles and four angles of slant. An adjustment method was used to record apparent slant. An analysis of variance showed significantFratios for visual angle and angle of slant thus supporting the hypothesis that increasing visual angle increases the effectiveness of slantjudgments.However, subjects' verbal reports indicated that slant may not beperceivedwhen only foreshortening is available as a cue.

摘要:

The fundamental premise of this paper is that subjects deal with stimulus information when performing psychophysical judgments. The coding strategy employed to manipulate this information depends upon the particular experimental procedure, which leads to unique psychophysical functions. Different methods impose different memory constraints upon the subject, thus producing a variety of sensitivity measures for the same stimulus attribute.

摘要:

Following Clark Hull, it is widely considered that the asymptote of the learning curve represents motivational factors, but that rate of approach to asymptote (‘i’) represents associational factors. The suggestion thatimay be a measure of intelligence was tested empirically in two studies. An initial exploratory study yielded a positive correlation betweeniand IQ. A more rigorous replication did not. The results are discussed brie

摘要:

Two samples of 178 boys and 238 girls answered a questionnaire dealing with nervous behavior in social situations. Factor analyses gave five factors in the study of boys and four in the study of girls. Rotation to a common structure showed at most four common congruent factors, which are interpreted and discussed.
