Five preschool children at risk for mental retardation were taught to choose an odd stimulus which varied in one important dimension (e.g., form, color, or size) from other stimuli in a set. Oddity responding was shown to transfer across stimulus types, and learning was maintained for a minimum of six weeks. (Author/JW)

Representational and transformational visual imagery instructions were manipulated within two passage types (name and occupation), along with no-strategy control instructions for each passage type. Transformational imagery instructions were effective on the more difficult to remember name passages. Representational imagery instructions were not…

Because disabled learners may profit from procedures using gradual stimulus change, this study utilized a microcomputer to investigate the effectiveness of stimulus equalization, an error reduction procedure involving an abrupt but temporary reduction of dimensional complexity. The procedure was found to be generally effective and implications for…

Evaluates the discrimination of signal and silence duration in six-month-old infants, children aged 5 1/2 years, and adults. Results show that infants discriminated duration changes of 20 milliseconds or greater, children discriminated 15 milliseconds, and adults as few as 10 ms. Findings are consistent with other research in revealing age-related…

Observation of eight-month-olds (N=7) during isolated free play session with three toys revealed that significantly more vocalizations were present during transition periods where changes from locus of attention and changes in facial expression occurred. (Author/CB)

A study investigated the manner in which linguistically normal (N=30) and language-impaired (N=30) 4- to 9-year-olds responded to stacked requests for clarification during a structured conversational task. Impaired and younger normal subjects had greater difficulty responding appropriately as the stacked sequence progressed. (Author/CB)

Maintains that before any real teaching can take place, art teachers must combat "visual fatigue,""media bombardment," and "sensory overload." Describes each of these phenomena and offers practical advice for overcoming their effects. (JDH)

Examines whether age-related differences would be observed between young children and adults for discrimination of synthesized, five-format consonant-vowel syllables that differed in voicing onset time of the initial consonants. (HOD)

Investigated stimulus context (therapy session versus therapy description) and stimulus medium (audiovisual versus written) in preferences for the behavioral and person-centered orientations. Behavioral orientation was preferred when both orientations were presented audiovisually as a therapy session. Conversely, the person-centered orientation…

Tau, Lambda, and Kappa are measures developed for the analysis of discrete multivariate data of the type represented by stimulus response confusion matrices. The accuracy with which they may be estimated from small sample confusion matrices is investigated by Monte Carlo methods. (Author/LMO)

Tests the hypothesis that habituation of attention to irrelevant information can account for within-task improvement in selective attention--that children who are preexposed to stimuli that will later be irrelevant in a speeded classification task will experience less interference than children not given the opportunity to habituate. (HOD)

Form-oriented errors of verbal inflection in speech are examined as indicators of cognitive processing in six experiments with college undergraduates. Appendices list words used as stimuli in the six experiments. (LMO)

An experimental lesson plan on sewing machine tension was developed for blind and sighted students in an attempt to teach this concept more effectively. Tactile/verbal aids were used in the experimental lesson to increase the potential for student comprehension. The experimental lesson produced better results for both groups of students even…

Examines, in three experiments, infant sensitivity at 20, 30, and 36 weeks of age to 3-dimensional structure of a human form specified through biomechanical motions. Findings are interpreted as suggesting that infants, by 36 weeks of age, are extracting fundamental properties necessary for interpreting a point-light display as a person. (Author/BE)

Describes a way of classifying and measuring the representation of the physical world and the use of metaphor in textbook illustration which is based on information content. It can be used to provide data to help in assessing the value of textbook illustrations and compare their illustrative styles. (Author/MBR)
