Infants who were in darkness were presented with objects that made sounds. Objects were within reach and out of reach. Infants reached into the target area more often when the object was in reach than when the object was beyond reach. Infants reached correctly in the dark for objects placed off midline. (BC)

Tested infants' latency in turning toward stimulus patterns and the duration of their initial fixation. Results showed that "turning latency" fell in a linear manner from 36 to 120 weeks after conception. Fixation time fell abruptly at 53 weeks. Preterm and full-term infants showed the same developmental trends. (BC)

Two experiments were conducted in an effort to determine whether young children overestimate message quality because they evaluate their knowledge or assumptions about the intended meaning of the message rather than its literal meaning. (PCB)

Sixty five year olds and their mothers were given the semiprojective, picture-based Separation Anxiety Test (SAT), which was scored to reflect attachment, self-reliance, and avoidance. Ratings were correlated with observed attachment status during a brief laboratory separation-reunion procedure. (DR)

Twenty-eight L-dyslexic and 26 P-dyslexic children (mean age of 9-10) received hemisphere-specific stimulation (HSS) by presentation of words to right and left fingers, respectively. Relative to controls, HSS-treated L-dyslexic subjects showed larger improvement of accuracy in text reading, whereas HSS-treated P-dyslexic subjects showed more…

Confirms the existence of a right-hemisphere advantage in the process of discriminating between face stimuli. The advantage was weaker in females than in males. No hemispheric transfer of learning was observed. Subjects were 18 infants of 42 weeks who were presented with an operant conditioning situation in which they discriminated between their…

Analyzes John Trumbull's documentary painting, "The Declaration of Independence," for its didactic importance. The painting actually represents the moment in which the declaration is presented to the Second Continental Congress, rather than the signing of the document. The historic and visual importance of the work for educators is…

Focuses on the relationship between loudness and intensity of sounds. (Author/PVD)

Focuses on the concepts of pitch and timbre of sounds. (PVD)

A study involving three adults with mental retardation found engagement in typical adult activities was greater when picture schedules were provided. The schedules provided a reminder for the adults and teaching counselors, provided an easy reference to assist them in determining the next activity, and reduced transition time between activities.…

Study 1 identified proximal processes in home environments of 78 children aged 6-9: maturity facilitation, use of stimulating materials, and parent-child relationship. Study 2 tested the Home Observation for Measurement of the Environment instrument for consistency and construct and criterion-related validity with samples of 307, 171, and 73,…

Discusses the use of quick-image activities in which the teacher flashes one particular image consisting of dots on the overhead projector screen for three seconds, hides it from view, then asks students to tell how many dots were shown and to describe what they saw. (ASK)

Proposes a composite feature measure which combines the shape and color features of an image based on a clustering technique. A similarity measure computes the degree of match between a given pair of images; this technique can be used for content-based image retrieval of images using shape and/or color. Tests the technique on two image databases;…

A study investigated the efficacy of texture fading in the treatment of food selectivity displayed by four children (ages 2-5). Successful treatment involved the gradual addition of higher textures based on results of periodic probes. Food acceptance and swallowing were reinforced, while food refusal and expulsion were placed on extinction.…

A study involving three adolescents with mental retardation investigated the efficacy of videotaped instruction for acquisition and generalization of functional sight words used in a community grocery store. Results indicate the intervention was effective in fostering acquisition of functional words in the classroom, as well as generalization to…
