A span-of-apprehension task and a backward masking technique were combined to allow measurement of the apprehension span of a sample of 34 learning disabled and normal boys about 8 to 13 years old at various time intervals following stimulus presentation. (Author/SW)

Investigates the sensitivity of children aged 6 to 10 to stylistic properties of line drawings. Subjects were asked to judge the similarity of 12 drawings which varied along the dimensions of clarity, expressiveness, and line thickness. In contrast to previous research, the youngest children had the ability to make multidimensional…

Impulsive second grade, inner-city children, were trained to improve their search strategies on visual discrimination tasks. Groups with training improved their search strategies, while the untrained control group did not. (ST)

Visual literacy refers to a group of vision-competencies a human being can develop by seeing, and at the same time having and integrating other sensory experiences. (Author)

Exposing subjects to pleasant and unpleasant pictures and odors separately and simultaneously, evaluative meanings were compared and correlations were derived. Very modest support was obtained for extending consistency theory to a limited case of cross-modalities." (DB)

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 effects of varying training settings and objects on the development of skill generalization were studied with 60 retarded students (5-16 years old). Research procedures were identical for all groups except for the manipulation of settings and objects. A factorial analysis of covariance supported the prediction that the visual discrimination…

The hypothesis that perceptual development proceeds from less to greater dimensional separability was tested by giving a speeded classification task to first and fourth graders. Results supported the hypothesis that development proceeds toward greater flexibility of attention rather than simply toward increasing separability. (Author/DB)

Differences in response of four- to seven-month-old infants to tachistoscopically presented photographs of two human faces suggest infants were able to remember a frequently presented face from trial to trial and discriminate it from a discrepant, infrequently presented face. Findings suggest event-related brain potential (ERP) responses could…

Contrast thresholds for sine-wave gratings of spatial frequencies of 2, 4, 12, and 16 cycles per degree were determined for normal and disabled readers at a range of stimulus durations. The differences in sensitivity pattern across spatial frequencies was greatest at stimulus durations approximately equal to fixation durations during reading.…

Supports the hypothesized distinction between Mongol children's visual-motor performance and their correctly perceiving visual designs. (Author/RL)
