The internal reliability of the Speech Sounds Perception Test was examined in two independent samples. Both indicated a significantly greater number of errors on the first half of the test; the largest number of errors occurred on Subtests B and A. Reliability coefficients and a performance classification formula are discussed. (Author/CM)

Examines periods of mutual gaze and visual coorientation between mothers and their two- to four-month-old infants as contexts for the utilization of maternal verbal control techniques. Additional questions involve the impact of infant sex and maternal sensitivity upon the utilization of these techniques. (Author/MP)

Three experiments employed rectangles in stimulus identification tasks. It was concluded that the initial perceptual processing of rectangles is accomplished by separate dimensional analyzers operating in parallel. Observers adopt different decision strategies for negatively correlated sets and for single dimension sets when the number of…

Tested 61 randomly selected college students to determine whether methodologies employed in psycholinguistic investigation of sentence perception can be used to ascertain how screen media communicate. The paralinguistic techniques were not transferable to the examination of visual perception. More than 60 references are listed. (FM)

The hypothesis was that the two hemispheres have different functions in normal vision, the dominant one analyzing the "figure," and the nondominant the "background." The investigation examined responses of 41 female psychology students. Results were consistent with the hypothesis. (Author/RD)

Research results show that it may be possible, within limitations, to facilitate discrimination by infants of inappropriate from appropriate verbal descriptions of a visual event, by emphasizing the agent component in a simple sentence. (Author/JB)

Sixty first-grade children were trained to categorize pictures of common objects. Results indicated that children who were taught an organizational strategy and who were given verbal instructions attained higher recall scores than children who were shown a specific strategy and who were taught using a question type format that encouraged…

The second in a series that discusses effective approaches to presenting information, this article examines six guidelines useful for translating a script into a memorable film or tape. Six references are cited. (Author/MER)

Repeated observations of a colored form results in slower reaction-time responses to the familiarized stimulus than to a comparable novel stimulus due to alertness decrement and encoding facilitation. This two-factor theory of repetition was found to hold for words as well as for colors. (Author/BW)

Research is reviewed on stimulus overselectivity in autistic children, and educational implications are discussed in terms of language acquisition, social behavior, observational learning, generalization, and prompting and prompt fading. Approaches to circumvent the problem of overselectivity are also described. (CL)

Newborns were presented with a tape-recorded rattle sound through a single loudspeaker, through two loudspeakers with one onset leading the other by seven msecs., and through two loudspeakers simultaneously. Newborns turned toward the single source sound, but not toward either of the dual source sounds. (Author/RH)

Presents results of two experiments which measured contrast sensitivity function in infants. Information concerning development of visual acuity, low frequency attenuation, and sensitivity to contrast were collected. Results provide an approximate picture of and means for detection of infants' pattern information. (Author/DB)

This research reexamined the hypothesis that recognition is a developmentally stable component of the memory system. Recognition performance was compared across age groups. Particular attention was paid to the role of response biases and perceptual skills in developmental increases in recognition performance. (Author/DB)

Tests the effects of stimulus variability on overgeneralization and overdiscrimination errors in children and adults. The subjects (n=64), adults and five-, seven-, and nine-year-old children, participated in a visual discrimination task. (CM)

In Experiment I, 24 preschoolers were tested on left-right, vertical-horizontal, and mirror-image oblique discriminations under essentially context-free conditions. Experiment II contrasted children's performance under context-free conditions with their ability to discriminate orientation in the presence of external visual cues. (RH)
