摘要:

Eight squads from an officers training school were given a sociometric questionnaire four times during a period of two months, and the sentiment structures of the groups at these points were compared by means of the structural balance index. The difficulties encountered when comparing non‐isomorphic structures with this index are discussed, and a strategy for acquiring a baseline for use in the interpretation of the data are proposed. Results indicate that increased positivist of the relations involved was the only systematic tendency in the development of the structure

摘要:

The fundamental premise of this paper is that subjects code information in such a way that a variety of psychophysical functions can be obtained with the same stimulus attributes. Four terms must be defined in order to understand psychophysical equations. These terms are: (1) The subject's perceptual channel capacity, (2) the subject's cognitive channel capacity, (3) the experimenter's measure of stimulus information, and (4) the context variables associated with the psychophysical procedure.

摘要:

Figural after‐effects (FAE) were studied using the Hering, the Ehrenstein, and the Orbisson illusion, patterns in two ways. In one condition, the total pattern was used as inspection figure (IF), and that part of the pattern in which the illusion normally appears, as test figure (TF). The resulting FAE was in a direction opposite to that of the illusion. In the second condition, the illusion producing part of the total pattern served as IF, and the illusion suffering part as TF. This produced an after‐effect, the direction of which was the same as that of the illus

摘要:

Operator tracking performance in 3 simulated guided missile systems was studied under short‐term psychological stress induced by threatening with and also delivering unpleasant electric shocks. The initial part of the stress period was characterized by a moderate decrement of performance and a heightened arousal level, which is regarded as a partial confirmation of the activation theory. The results may also be interpreted in terms of a simple stress‐over‐time model, based on a hypothetical interaction between arousal and habitu

摘要:

A model described by the relation, relative estimated time = (subjective space)/(subjective velocity), is applied on time estimates collected in three experiments with moving spots indicating the time intervals which were estimated. The model is found to account satisfactorily for the data, thus permitting derivations of subjective scales of velocity and space.

摘要:

To test the hypothesis that perceived size of space depends on perceived depth, a relation between judged depth and size of space was derived. External spaces were judged from colour photographs by the magnitude estimation method. It was found that judged depth is a power function of physical depth and judged size of space a power function of physical size (rectangular area) or of judged depth times perceived width. The results indicate deviations from the derived relation and some explanations for these are discussed. Further research is needed to verify the proposed hypothesis.

摘要:

Judgments of depth and size of space were obtained by the magnitude estimation method under (i) binocular viewing of actual spaces, (ii) monocular viewing of colour photographs, (iii) monocular viewing of detailed drawings, and (iv) monocular viewing of undetailed drawings. Judged depth and size were found to be power functions of the physical measures. The exponents decreased successively under conditions (i)‐(iv). Judged size (rectangular area) might be a power function of judged depth times perceived width. The hypothesis was substantiated that perceived size of space depends on perceived dept

摘要:

The traditional conception of achromatic colour constancy, defined in terms of a psychophysical colour‐albedo relation, is found to be unfruitful from a functional as well as a theoretical point of view. An alternative definition of colour constancy in terms of the validity of perception of illumination is suggeste

摘要:

Two hypotheses regarding the role of eye movements in reversibility of perspective were tested by having the subjects observe a reversible‐perspective figure during normal and stabilized viewing. No difference in reversal rate was found between the two conditions. It is concluded that reversibility of perspective remains unaffected by the presence or absence of eye movement
