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)

Study measures the precision of auditory localization in 26- to 30-week-old infants using the adult minimum audible angle test. Results show that infants discriminate sound displacements of about 19 degrees, considerably less accurate than adult values of one to two degrees. (Author/RWB)

This article reviews the history, the use and the reasons for abandonment of the selective adaptation paradigm. The four experiments mentioned in the article show that selective adaptation produces strong reaction time effects, and that items in the adapted category are identified more slowly than unadapted items.

Investigation of the reinforcing properties of vestibular stimulation with five multiply disabled severely retarded young children indicated that vestibular stimulation (10 seconds of swinging) was reinforcing to all subjects and was preferred (over food, praise, visual, and auditory stimulation) by four of the five children. (Author/DB)

Exclusion of stimuli involved in complex stimulus relations was examined in a severely retarded young man. The study systematically replicated and extended research on exclusion performance of low-functioning mentally retarded individuals and provided additional data on relational learning in this population. (Author/CL)

Programs were designed to teach three severely retarded adolescents to use individual anagram letters to construct the appropriate color words when shown color patches. After learning visual equivalences between colors and printed words, Ss demonstrated auditory reading-comprehension (matching printed words to dictated words) and oral reading…
