Examines Kail's argument that similarity in developmental speed-of-processing curves for name retrieval and mental rotation indicates that performance on a wide range of cognitive tasks is constrained by growth of a central limiting mechanism. Results suggest that operation of this mechanism is neither sufficient nor necessary to generate the…

Two experiments investigate children's knowledge about attentional capacity limits. Preschool children aged three and four years are asked to choose whether they will listen to pairs of stories simultaneously or one at a time. Results demonstrate a preference for listening to one at a time. (Author/RWB)

Examines developmental change in 4- 7- and 10-month-old infants' perceptions of correlations among attributes to determine whether relational information plays a role in abilities ranging from the perception and recognition of a simple pattern to the formation of a category. (HOD)

Examines kindergartners' and second graders' knowledge of concept attribute importance and the children's use of this knowledge to categorize. (HOD)

Perceptual counterparts of a series of conservation of length tests were presented to subjects who were categorized as conservers or nonconservers conservation of length pre-tests, and to conservers and nonconservers given conservation length training. Perceptual performance of the untrained nonconservers was significantly worse than that of the…

This is a developmental study of the effects, and role, of imagery in retrieving information from long-term memory. In two blocks of trails, first graders, fourth graders and adults determined whether or not various animals are characterized by various properties, first upon consultation of a visual image and then without imagery. (Author/SB)

Results clearly demonstrated the existence of perceptual sets in children under 4 years. The interpretation of findings suggests a process whereby the present method was successful in creating the mediating conditions necessary for a perceptual set. (Authors)

It was concluded that while retinoblastoma per se is not associated with intellectual superiority or inferiority, retinoblastoma associated with blindness may result in selective cognitive superiority. (Authors)

Study concerned with the mechanisms in terms of which the developmental transformation from one cognitive structure to another occurs. (Author)

After viewing pictures of simple objects varied in color and spatial location, first, third, and fifth graders were assessed for their abilities in automatic processing of spatial and color information. In general, no evidence was found to suggest that the processing strategies of younger children were less sophisticated than those of older…

Children 10 to 14 years of age tried to identify and remember words presented visually with a backward mask. On different tasks, children recalled freely or serially, recognized by making a rapid forced-choice response, or simply named words as they were presented. Results were interpreted as identifying two sources of developmental and individual…

The performance of children ages three through eight years on a series of class-inclusion problems was examined in two studies. Three patterns of performance were observed: three- and four-year-olds responded in an approximately haphazard pattern, five- and six-year-olds tended to be consistently wrong, and seven- and eight-year-olds showed a…

In a series of three experiments, first-, second-, third-, and fourth-grade children were asked to recall the names of their classmates. Assessment of their organization according to various classroom groupings (e.g., seating arrangement and reading group) was then performed. (Author/MP)

Reports three experiments which investigated the ability of children aged four to nine years to organize body-location information in recall. Attempted to correct for methodological confounding in previous similar research. (JMB)
