Two studies examined whether infants' category discrimination in an object-examination task was based solely on an ad hoc analysis of perceptual similarities among the experimental stimuli. Findings indicated that 10- to 11-month- olds' responses varied systematically only with the presence of a category change, but not with the degree of…

A study assessed whether a program involving simple hand-movement responses combined with optic microswitches and followed by preferred stimuli would be successful with two persons with multiple disabilities (ages 11 and 30). Data showed participants reached fairly high levels of responding during intervention and retained their achievement…

This study assessed cognitive processing speed among full-term and preterm infants when they reached 5, 7, and 12 months of age. Findings indicated that at all ages, preterms required about 20 percent more trials and 30 percent more time than full-terms to reach criterion on a novelty preference task. Among preterms, slower processing was…

Data collected from young adults in a life skills course with collage and stimulus instruments were classified as follows: reaction, remembering, learning, behavior change, and life philosophy. Pictorial stimuli proved effective in assessing affective goals and usefully supplemented other forms of assessment. (SK)

In this study, non-French participants learned gender-appropriate adjectives for 24 French nouns. Findings indicate that learning the same set of feminine French nouns could be made more or less difficult when the nouns in the masculine category created more or less competition.

A study examined three different visual formats (studio presenter only, realistic visuals, or schematic visuals) of an educational television program. Recognition and recall of the abstract subject matter were measured in 101 adult viewers directly after the program and 3 months later. The schematic version yielded better recall of the program,…

An auditory technique for studying semantic priming and lexical access, single-word shadowing, was applied in three separate experiments: priming in word pairs; priming in sentence context; and comparison of priming in children aged 7-11 and elderly adults. Results indicate that, because shadowing works across ages and does not require reading, it…

The behavioral and heart rate responses of 22 children (ages 3-4) with autism and 22 with other developmental disabilities were compared while they were watching videotapes of a baby either playing or crying. Both groups of children showed heart rate slowing when watching the video of the crying baby. (Contains references.) (Author/CR)

Three experiments investigated 2- to 6-month-olds' perception of the continuity of an object trajectory that was briefly occluded. Results across experiments provided little evidence of veridical responses to trajectory occlusion in the youngest infants, but by 6 months, perception completion was more robust. Results suggest that perceptual…

Three studies explored whether children's tendency to extend object names on the basis of sameness of shape (shape bias) is specific to naming. Findings indicated that 2- and 3-year-olds showed shape bias both when asked to extend a novel name and when asked to select an object of the same kind as a target object; 3-year-olds also showed shape…

This paper offers training strategies designed to help profoundly hearing-impaired children learn to use information delivered via the Tactaid II+, a two-channel vibrotactile device. The paper describes function and monitoring of the aid, training activities, realistic and unrealistic goals, and a case study illustrating speech perception…

Two time-delay conditions for teaching complex visual discriminations to 14 normal preschoolers, 12 with mild mental retardation, and 11 with moderate mental retardation were compared. Results indicated that for all populations and stimuli, time delay of multiple dynamic distinctive-feature prompts produced learning, while time delay of the single…

Twenty language-delayed children (age three to six) viewed a presentation incorporating object, action, attribute, and affective state words into a narrative script. In pre- and postviewing word comprehension measurements, subjects scored lower than children matched for chronological age and children matched for mean length of utterance.…

Five young adults and three junior high students, with moderate mental retardation, were trained first to label characters verbally and then to enter the characters into computers, calculators, or checkbooks. Almost all subjects were able to generalize the use of verbal labels and key-entry skills across tasks and settings. (Author/JDD)

Uses a spatial model to examine the relationship between stimulus exposure, cognition, and affect. Notes that this model accounts for cognitive changes that a stimulus may acquire as a result of exposure. Concludes that the spatial model is useful for evaluating the mere exposure effect and that affective change does not require cognitive change.…
