Four experiments show that observers can selectively attend to one of two stationary superimposed pictures. Selective recognition occurred with large displays in which observers were free to make eye movements during a 3-sec exposure and with small displays in which observers were instructed to fixate steadily on a point.

The time needed to process visual feedback information for the control of aimed movements was investigated in two experiments. Examination of movement patterns indicated that the average time between presentation of visual error information and initiation of a movement correction was 135 msec, which is shorter than previous estimates.

How strategies affect learning of categories that lack necessary and sufficient attributes is explored. The authors propose that strategy variations induced by instructions affect only the amount of information represented about attributes, not processes operating on representations. An experiment required subjects to classify schematic faces into…

The effects of stimulus duration and contrast on duration of visible persistence as a function of spatial frequency were investigated in normal and specific-reading-disabled children. Results suggest that disabled readers have different contrast processing at low and high spatial frequencies and indicate differences between readers in basic visual…

Thirteen hyperactive males (ages five through eight) were rated on activity prior to, during, and after a period of ascending music stimuli. It was hypothesized that they would become less active during, rather than before or after, the stimulus. Activity significantly increased during the music program, thus rejecting the hypothesis.

Expressive language samples were obtained from 20 children in four location-stimulus combinations and from wireless radio telemetry. No significant differences existed between the locations of home and clinic, but significant differences were noted among samples elicited using pictures as opposed to open-ended questions as compared to telemetry…

Behavior modification in a weight control program is examined in two models of operant and classical conditioning. Successful utilization of behavioral techniques is dependent on adherence to principles of learning, the skill and insight of the clinician, and the sensitivity to the individual needs of each client.

Twelve first-grade children were tested on word-reading and automaticity of letter and word processing. Word-reading speed increased steadily during the year. Apparently, their ability to process letters automatically was acquired prior to the ability to read words rapidly and accurately. (Author/CP)

Timeout from auditory reinforcement was employed to reduce rates of target responses of two mentally retarded children (9 and 11 years old). Results supported the response deceleration characteristic of timeout from auditory reinforcement and indicated its effectiveness as a response reduction technique. (Author)

Shows how photographs of teenagers were used to trigger high school students' creative writing. Provides samples of student poetry. (RL)

One hundred thirty-six 5-to-10-year-old Israeli children were given three black and white photographs of a highway, a column of identical tanks, and a row of elephants, and were asked some questions on each one of the photographs in order to elicit responses of three-dimensional perception. (CM)

A comparative assessment of eight normal and eight psychotic children in a stimulus generalization paradigm using simple and complex figures. Six of the subjects fulfilled the criteria for infantile autism. (CM)

Establishes the validity of the Picture Potency Formula as a tool to predict the extent to which children will respond to pictures. (FL)

Forty elementary children (six and nine year olds) and 20 college students were required to discriminate identical pairs of visual stimuli from mirror images. It was hypothesized that a key factor in performance would be the extent to which orientation was a functionally significant attribute of the stimuli. (Author/MP)

Examines the effect of various encoding activities on the memory of elementary and college students for pictures and words. (MP)
