Four major types of interaction of stimulus dimensions based on perceptual research are described: integral, configural, separable, and asymmetric separable. Implications of these interactions for concept and choice processes are discussed. (Author/DEP)

The extent of the cognitive equivalence between a picture and the depicted object is the result of an interaction between the picture and the observer. The observer's reaction is largely determined by his pictorial sophistication and cultural background. (Author/STS)

Results suggest that the technique employed in static background displays may be an important determinant of a speaker's impact on television viewers. (Author/STS)

The ability of 7-, 8-, and 9-year-olds to understand proverbs was examined by having subjects compare each proverb against two thematic pictures: a nonliteral correct interpretation of the proverb and a foil. The results, which contradict the literature, showed consistent above-chance performance across subjects, ages, and proverbs. (Author/JMB)

Thurstone's landmark papers on psychophysics, published in the twenties, are discussed in this presidential address to the Psychometric Society. The development of psychophysics from Thurstone to the present is presented in some detail. (JKS)

In general, the present study finds cross-cultural agreement between American children and Baganda children and adults on the recognition of happy and sad expressions. The happy expression is more easily identified by young children than the sad expression. (Author/AM)

Concludes that the significant difference found between responses made to displayed drawings and those made to models suggests that, independently of the complexity of stimulus, encoding will not influence responses if the very economical process of simple coding can be used. (Author/AM)

One-hundred and forty-four retarded persons, at two MA levels (11 and 6.5 years) were exposed to a list of paired-associates in which the stimulus terms were picture compounds of one animate and one inanimate object. (Author)

The figural simplicity or salience of parallel lines was studied in 3- and 4-year-olds by means of a figural matching procedure where parallelism was a basis for judging similarity. (Author/JMB)

This article reports two attempts to demonstrate the discrepancy hypothesis prediction that visual fixation time for human infants should be an inverted-U function of the magnitude of discrepancy between a new stimulus and a familiar standard. (Author/JMB)

Illustrates the stimulus addiction chain experienced by a substance addicted person and recommends that substance abuse treatment agencies provide low-stimulus activity by controlling their use of high-stimulus structure and high-level recreational stimulus producers. Suggests quiet activities to help regulate stimulus and reinforce reflectiveness…

Studies investigated the development of children's ability to differentiate what they see from what they know in the context of conceptual perspective taking. Two developmental levels accounted for children's performance when they were asked about a naive observer's knowledge of the identity of objects. Perspective awareness training improved…

Findings indicate that infants can detect regularity in spatiotemporal series; will develop expectancies for events in the series; and will act on the basis of those expectancies even when their actions have no effect on the stimulus events. (PCB)

Study tests 45 four-month-old infants for color constancy using a familiarization, paired-comparison paradigm. Infants tested with a change in illuminant correctly recognized the familiar color under some conditions and failed to do so under others. (Author/RWB)
