This experimental study has three aims: (1) to give a detailed description of imitative behavior as it develops during the first six months of life; (2) to compare imitative responses perceived through visual, kinesthetic and auditory modalities; and (3) to describe and explain the regulating mechanisms and processes present in the early…

A research project involving 16 experiments investigated the nature of the encoding process for verbal materials, particularly differences arising from mode of presentation. The results showed that a change in mode of presentation of items produced a recovery from interference in short term retention. Since intermodal interference was lower than…

How the mode of input of stimuli affects the quality or type of response was studied by comparing the number of paradigmatic responses and syntagmatic responses to both orally and visually presented stimulus words. The following groups, totaling 194 subjects, were involved in four experiments: (1) 18 institutionalized disturbed adolescents, (2) 96…

Incidental learning in 8- and 12-year-old children was assessed with a variety of stimulus materials. Experiment 1 compared two types of material; (a) geometric figures, whose central and incidental components were shape and color, respectively and (b) stimuli whose components were separate pictures, as in the typical developmental study of this…

Eighty-six undergraduate males participated in an experiment designed to investigate the impact of various types of erotic stimuli upon aggression. On the basis of previous research, it was hypothesized that exposure to mild erotic stimuli would tend to inhibit subsequent aggression, while exposure to more arousing stimuli of this type would…

A group of language class activities use photographs to encourage students to identify, describe, imagine, recount, and persuade in a variety of ways. (MSE)

Describes procedures and equipment needed to develop and organize a collection of 35 millimeter slides useful in the teaching of Latin American language and area studies to students of Spanish. (CB)

Three severely mentally retarded, multiply handicapped adolescents were treated in a classroom setting for social skill deficits. Treatment focused on increasing eye contact and strengthening on-task and in-seat behaviors. Results suggested that a combination of visual stimuli, operant, and social learning methods can be used to successfully…

Examines interactions between timing accuracy and muscular parameters in children aged five who performed a visuomotor game. Five images were successively presented on a television display at precisely timed intervals for a total period of 11 seconds. Results suggest that timing accuracy is dependent on action-produced sensory cues. (RWB)

Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classifications of younger and older subjects. Results support a differential-sensitivity view of perceptual development which asserts that individuals at all ages primarily perceive and use separate relations. (RWB)

When learning-disabled high school students (N=22) were taught about astronomy by either presenting key concepts with a visual spatial display or by presenting concepts with texts, tests measuring short-term mastery of content favored students taught with the visual display. No differences were found between the groups on transfer or maintenance.…

Three studies assessing language comprehension of infants and toddlers through a method requiring a minimum of motor movement, no speech production, and differential visual fixation of two simultaneously presented video events provide insight into children's emerging linguistic capabilities and help resolve controversies about language production…

A university second language program using associative learning and context to enhance retention of words, expressions, and structures is described. Observed results of this situational approach are discussed. (MSE)

A study of 12- to 14-year-olds was conducted to investigate which components of spatial ability may be dependent on general cognitive functioning level and to compare possible differences in carrying out certain spatial operations in children of equal intelligence, but who are not specifically gifted for mathematics or visual arts. (MBR)

Describes methodology and results of a study examining the role of layout and graphic design in the legibility of instructional text displayed on cathode ray tubes. This report includes a multidimensional scaling analysis, an analysis of the stimuli and independent variables, and labeling and dimensions using adjective and interview data. (MBR)
