"This concluding article provides the first published account of a series of psychological experiments which are presently being undertaken by the Schools Television Research Project, examining presentation factors in instructional television. (Editor)

The relationship between sign and verbal learning was explored using 10 severely mentally retarded adults. They were taught color labels in sign, verbal, or sign and verbal groups. Sign labels tended to be learned more efficiently; combined sign and verbal training improved verbal learning but not sign learning. (Author/CM)

The phenomenon of more interference with reading than with listening was replicated using speech-related and nonspeech-related distractor tasks. It is argued that the selective interference effect is due to the relative difficulty of reading over listening rather than to the importance of speech recoding in reading. (Author/RD)

Reviewed studies that used methods of brief lateral visual presentation of linguistic stimuli to investigate asymmetry of organization in the cerebral hemispheric functions of both normal and poor readers. Most studies failed to demonstrate that both groups approach the given tasks in the same way. (Author/DB)

Assesses the impact of the visual complexity of "Sesame Street" segments on preschoolers' visual attention, recall, and recognition. Results indicate that attention and learning are enhanced by (1) visually simple sets in terms of few objects on the screen and (2) low to moderate levels of screen activity. (PD)

Four experiments demonstrated that mental images are functionally equivalent to physical errors of movement in producing changes in visual-motor coordination, at both central and peripheral levels of the visual-motor system. Subjects observed or imagined pointing errors after pointing movements were completed. Imagery vividness ratings were also…

Earlier research with the lexical decision task led to the hypothesis that semantic context facilitates the encoding of words related to the context. Six experiments which employed different tasks (e.g., making a lexical decision) and different experimental paradigms (e.g., tachistoscopic exposures with masking stimuli) further investigated this…

First, third, and eighth graders performed four different orienting activities to different words. Under an incidental learning paradigm, the children's recognition was tested after the orienting activity. Age differences in recognition were absent, and the effect of the orienting activity responses on recognition supported depth of processing…

Results of perceptual tests administered to 50 retarded readers and 50 average readers in third grade indicated a significant difference between the two groups on visual sequential memory for letters. (CL)

This study sought to develop the picture-interpretation strategies of fourth-grade children by providing training in the use of such verbal guidelines as "Help yourself to all the given information." The program apparently helped the children produce more inferences, but did not enhance their skills in evaluating inferences. (Author/JEG)
