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)

"Grandfather Moose" rhymes, written to follow the Mother Goose tradition, are short, appealing, easy-to-memorize sign language nursery rhymes which employ visual poetic devices such as similar signs and transitional flow of movement. (CB)

Three categories of information were hypothesized to be important information for successful execution of procedural assembly tasks: operational, spatial, and contextual information. Performance data for two tasks indicated that subjects using "complete" instructions finished the assemblies in less time and with fewer errors than did…

Confirms that both kindergarten and third-grade children communicate more accurately about familiar referents than about novel referents in a referential task. (PD)

Samples of institutionalized and noninstitutionalized children and adults were asked the same questions with and without accompanying drawings intended to clarify question content. Drawings had no impact as an adjunct to yes-no questions but did improve responsiveness to multiple-choice and either-or questions. (Author/ABB)

Observations of three parent-child dyads seeking help for severe interactional problems provided tentative support for the predictability hypothesis, which suggests that social interactions are most likely to function as aversive stimuli when delivered in unpredictable fashion by either party and that responses instrumental in reducing…

Summarizes results from a series of psychological experiments about how people process information from television and discusses the results in relation to six issues, including size of stimulus units and complexity of television stimuli. (DF)

Studies 45 low-medical-risk preterm infants and 23 healthy term neonates, revealing that preterms are more wakeful but not more visually responsive than full-term infants. Intrameasure correlations suggest that the organization of wakefulness and visual responsiveness is different in full-term neonates and in preterms at expected date of birth.…

Finds that seven-month-old infants are sensitive to pictorial interposition whereas five-month-old infants are not. Suggests that sensitivity to pictorial depth information first appears between five and seven months of age. (Author)

Both male and female 15- to 21-year-olds (N=466) with trainable mental retardation were taught to view assembly drawings as the instructional cue to assemble a complex industrial item. The IPEV drawings were an alternative to task-by-task role training. (CL)

Thirty-two three-month-old infants participated in two experiments showing color videotapes of facial stimuli in a paired comparison format. Suggests that contrast in effect of eye contact availability and rather subtle stimulus motion (blinking) implies that three-month-old infants are comparatively insensitive to being the object of another's…

Infants, preschoolers, and adults were tested to determine the shortest time interval at which they would respond to the precedence effect, an auditory phenomenon produced by presenting the same sound through two loudspeakers with the input to one loudspeaker delayed in relation to the other. Results revealed developmental differences in threshold…

The need for developing a technology of teaching that equals current sophistication of microcomputer technology is addressed. The importance of principles of learning and behavior analysis is emphasized. Potential roles of stimulus control and precise error analysis in educational program development and in prescription of specific learning…
