In a study to determine whether or not culturally deprived children develop at progressively greater deficits in intellectual functioning during the ages of 15 months to 3 years, tutors provided 15-month-old infants with intellectual and verbal stimulation one hour daily, five times a week until they were 36 months old. The subjects consisted of…

The purpose of this study was to see if a change in environment affected the rate of sensorimotor development in infants. First a control group of institutionally-reared infants aged 1 to 6 months was observed to determine average age of visually directed reaching, visual exploration, visual accommodation, and the blink response. Then the…

This paper examines the development of visually evoked EEG patterns in retarded and normal subjects. The paper focuses on the averaged visually evoked potentials (AVEP) in the central and occipital regions of the brain in eyes closed and eyes open conditions. Wave pattern, amplitude, and latency are examined. The first section of the paper reviews…

Special equipment was used to record the eye movement patterns of 60 children enrolled in a reading clinic. There were 20 children in each of three groups: good readers, slow readers, and non-readers. The children were shown printed material on a screen accompanied by action sequences and voice recordings similar to what they might see on…

Twenty children in each of grades 2 and 4 were given a reaction time task of the type in which Sternberg (1969) shows high-speed, serial, exhaustive scanning of information in memory. On each trial subjects were asked to memorize two, four, or six pictures and were then presented with a single picture probe. The subject made a key-pressing…

This study examines the influence of maternal predispositions toward sex-appropriate behavior and the mother's response to "feminine" or "masculine" cues in infant behavior. In the investigation, one 6-month-old male infant was presented to 11 mothers who served as subjects. The infant was dressed as either boy (blue clothes) and named Adam, or…

The Connecticut School program for migrant children which was conducted during the summer of 1968 implemented several innovative projects. Among these were dietery aides, visual stimulation for oral development, and parental participation. Ancillary services were also provided by the program; it was found that a large number of children, mostly…

This study analyzed the effect of various stimuli on the number and kinds of words produced, the number and length of grammatical structures formed, and the quality of writing produced under four stimulus conditions. Third-grade students from Clarke County, Georgia, wrote compositions after (1) being asked to write a story (minimal stimulus); (2)…

Professional workers can assist parents of retarded infants by (1) helping them to recognize and cope with their feelings of guilt and despair, and (2) establishing a home program of exercises to allay the infant's inertia. Such exercises have been demonstrated by numerous investigators to be of positive value in improvement of motor performance.…

The present series of studies was undertaken to explore intersensory processing in the very young. In the first experiment 1-, 4- and 7-month-old infants experienced simultaneously their mothers' faces and voices. The various conditions consisted of displacing the voice from the face. The results indicated that infants as young as one month of age…

A highly interactive multicamera-multimonitor closed circuit television system is described which permits a resource room teacher and her handicapped elementary school students to be in continuous visual communication with one another. On the basis of relatively short-term observation, data is reported to show that the system is of most help to…

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…
