Discrepancy between angl head turn and loudspeaker location was measured on infants in auditory-alone and auditory-visual trials. Age and loudspeaker location had no effect on performance in auditory-visual trials. However, in auditory-alone trials, there were significant age differences. (PCB)

Demonstrates young children's shift toward a taxonomic basis for organization of both named and depicted objects. Concludes that perceptual organization in young children cannot be attributed to an inability to ignore visual information but seems to be based upon the centrality of perceptual features to the representation of objects.

Three experiments tested for developmental changes in attention to auditory and visual signals. Results showed that adults and seven-year-olds tended to allocate their attention to vision rather than audition when no precue was provided. While not entirely consistent, results with four-year-olds suggested a similar biasing of attention to vision.…

The incidental memory of young children was tested for words or words plus pictures that were initially presented under orienting conditions. These conditions required responses to acoustic or semantic qualities of the stimuli and an affirmative or negative response to the orienting questions. (PCB)

A stages-of-learning model was used to examine effects of picture-word manipulation on storage and retrieval differences between disabled and nondisabled grade 2 and 6 children. Results showed that disabled students are poorer at memory tasks and in developing the ability to reliably retrieve information than nondisabled children. (Author/RH)

Results showed that infants can differentiate dynamic, multimodal expressions as early as five months of age; can distinguish dynamically distinct expressions before similarly animated expressions; and seem to rely more on the voice than the face in making these discriminations. (RH)

Second-graders, fifth-graders, and adults participated in an experiment of cued recall for cue-target picture and word pairs. Results suggested that differences in the encoding of both specific and categorical attribute information contribute to developmental recall differences independently of encoding intent and stimulus modality. (Author/CB)

Thirty young and 10 elderly adults were assessed on orienting auditory attention, in a mixed-modal condition in which stimuli were either auditory or visual. Findings suggest that the mechanisms involved in orienting attention operate in audition and that individuals may allocate their processing resources among multiple sensory pools. (Author/JDD)

A go/no-go conditioned head-turn paradigm was used to examine the abilities of 6- and 12-month-olds to discriminate changes in temporal grouping and their perception of absolute and relative timing information when listening to patterns of white-noise bursts. (Author/RH)

Five experiments using identical reflex modification procedures on neonates and adults suggest developmental differences in processing auditory stimuli. Neonates failed to exhibit reflex inhibition by either prior acoustic or tactile stimuli. Adults exhibited robust reflex inhibition to these same stimuli. Developmental processes implied by these…

Studies investigated the development of children's ability to differentiate what they see from what they know in the context of conceptual perspective taking. Two developmental levels accounted for children's performance when they were asked about a naive observer's knowledge of the identity of objects. Perspective awareness training improved…

Compares comprehension monitoring skills of younger (five- to six-year-old) and older (eight- to nine-year-old) children. Subjects examined ambiguous and incomplete pictorial instructions for making two models and were asked whether they needed additional information to make the models. (RH)

The matching-to-sample performances of three young adults with autism and four children (ages four to nine) without intellectual disabilities were examined in three experiments using complex sample stimuli. Results for all subjects showed that each of two redundant relevant sample elements and their respective comparison stimuli were substitutable…

Results of a study involving 30 infants of 14, 20, or 26 weeks confirm the existence of distinct developmental phases of attention during the visual preference procedure. Findings suggest a refinement of the use of fixation duration as the major dependent variable in the procedure. (RH)

Twenty mildly mentally retarded adolescents were matched with two groups of nonretarded students, one of the same chronological age (CA 16) and the other of the same mental age (MA 9), to examine the influence of age and metamemory on recall. This was achieved using an adapted metamemory instrument which included relevant recall tasks. (Author)
