To determine whether the failure of previous studies to find a difference between the performance of children and adults in picture recognition tasks might be due to the number, selective content, and organization of the pictures used, 153 children at five ages (5.9 to 21.9 years old) viewed 150 slides.

Third- and sixth-grade readers were asked to label sets of pictures printed with distracting words (either nouns, adjectives, or functors) and nonsense syllables. (Author/JMB)

Two experiments explored whether stimulus familiarity influences prerecognition processing to generate differences in the apparent duration of tachistoscopic flashes. Subjects were 4- and 5-year-old children and adults. (MS)

The purpose of this research was (a) to determine whether or not an emotional response, as measured by palmar skin conductance, does accompany a critical item, and (b) if it does, to investigate its relationship to the deficit in recognition memory. (Author/RK)

Two studies: (1) assessed the infant's ability to perceive differences between two-dimensional and three-dimensional stimuli; and (2) tested the infants' ability to transfer responses across dimensions. (Author/SB)

Examined length of fixation time responses of neonates to pairs of red, blue, and green acetate stimuli. (Author)

Three studies of stereotyped object behaviors conducted with 10 severely mentally retarded children (6 to 19 years old) found that context did not affect the level of object stereotypes, that most children responded to flexibility, and that judges could estimate only some of the feedback properties of the objects.

Among 40 reading disabled volunteers (ages 9-74), subjects with high scotopic sensitivity demonstrated significantly better performance on visual processing tasks when they used colored overlays which maximized visual efficiency, compared with task performance under conditions using overlays of a random color or no color.

The study compared the effectiveness of a traditional training procedure (least-to-most restrictive prompt sequence) and a prescriptive training procedure (utilizing ongoing behavioral assessment data to identify discriminative stimuli) with four severely/multiply handicapped students (ages 11-19). Results indicated both procedures were effective…

Research regarding the characteristics and applications of "errorless" learning methods (stimulus shaping, stimulus fading, and superimposition) indicates that such methods provide a means of designing instruction and materials to facilitate the acquisition of skills, with minimal or no errors, by "difficult to teach" students.…

Direct care staff were taught via picture programs to transfer nonambulatory, severely mentally retarded men between their beds and wheelchairs. The still color photographs illustrated procedures and the addition of study guide questions increased the program's effectiveness. (Author/DB)

Based on a three-stage model of memory coding, comparisons were made between reading ability groups on their serial recall of pictorial information. Article describes three different experiments. (RB)

Two different methods which minimize achromatic cues were used to test the ability of one-month-olds to discriminate gray from broadband blue. Test data imply an improvement between birth and one month of age in the discrimination of gray from broadband blue. Possible physiological changes underlying this improvement are discussed.

The theory proposed (recognition-by-components) hypothesizes the perceptual recognition of objects to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components. Experiments on the perception of briefly presented pictures support the theory. (Author/LMO)
