Two university professors offer advice, based on their experiences, for using a variety of forms of visual displays to enhance lectures. (LS)

Suggests using the overhead projector as a tool in prompting students to extend their interpretation of concrete, or Gestalt, poems. (RD)

Described are some of the applications found in teaching retarded children for the Dynalevel, an instrument which "transforms the loudness of sound into light to provide a visual check on the tone intensity. (Author/LS)

To explore possible age differences, the first experiment assessed speed and maintenance of alertness in 5-year-olds, 8-year-olds, and adults. The second study tested the hypothesis that developmental variation in processing speed observed in some studies was attributable in part to age differences in alerting processes. (MP)

Training improves the ability of human observers to discriminate between two similar directions of motion. This gradual improvement is specific to the direction on which an observer is trained, enduring for several months. Improvement does not affect motion perception generally, nor does it depend on recognition of details of the movement. (Author)

The apprehension spans of learning-disabled and normal boys were compared by means of a forced-choice letter-recognition task involving tachistoscopic exposures of letter displays. Results of three experiments indicated that the decreased spans of apprehension observed in the first experiment for learning-disabled boys resulted either from greater…

Results of an initial experiment show that motoric imagery can produce relatively large increases in the ability of young children, as well as adults, to recall meaningful sentences. Results of a second experiment show that motoric imagery can, to some extent, facilitate free recall of word lists when visual imagery has no effect. (Author/RH)

One hundred undergraduates learned lists of high- or low-imagery nouns in one column (ungrouped) or in three columns (grouped). Grouped-list recall was significantly greater than ungrouped on the third and fourth trials. Spatial grouping seems to provide important cues which are independent of the words learned or imagery level. (Author/CM)

When two nonoperative lights were added to each of the ends of a stimulus display in a four choice reaction time (RT) task, the RTs of mentally retarded and nonretarded young adults Ss were slowed to about the same extent. (Author)

With the use of a probe-type serial memory task, hearing and deaf children matched on chronological age, IQ, and sex were randomly assigned to named, unnamed, or dactylo-kinesthetic (finger spelled) stimulus pretraining conditions and compared on subsequent recall performance. (Author/MP)
