As age and grade increased, recall on all tasks increased; subjects in grades three to six were also seen to have a fully developed Iconic Memory, while only sixth graders had a functionally developed Immediate Memory. (KR)

Investigates the possibility that age-related increases in free recall are due in part to the more flexible manner in which older children retrieve information about items they have encoded. Subjects were 72 children aged four, seven, and ten years from English nursery school, (second and fifth grades.) (Author/MP)

During individual interviews, each of 64 subjects, aged 8 to 14, generated a peer perception grid in which 17 supplied figures were rated on 10 individually elicited bipolar concepts. Three aspects are examined: attributional characteristics of concepts, level of differentiation between peer figures, and organizational complexity of relations…

Subjects in three age groups (N=96) who resided at home were tested on appreciation and comprehension of 12 conservation and 12 nonconservation jokes. Cognitive perceptual theory of humor applies in old age as in childhood, with appreciation depending on a match between ability level and cognitive demand of the joke. (Author)

Elementary school and college students acquired a paired-associate list under the study-test procedure to a one errorless trail criterion. In addition, as each pair was presented the individual indicated whether she/he had that pair correct on the immediately preceding trail (post-diction responses). (Author/SB)

Reports two experiments designed to assess the influence of stimulus meaningfulness on processing time with children of differing ages. (BD)

Developmental changes in 5- to 7-year-old children's mental representation of addition and subtraction events were examined by means of the response times required to answer more or less questions. (Author/JMB)

A series of three experiments was conducted to verify the hypothesis that age differences in paired-associate learning proficiency across adolescence stem from the development of increasing eleaborative propensity. (Author/JMB)

Children 3 1/2 and 5 years of age were tested for their intuitive knowledge of the psychological fact that one mental event may trigger or cue another related mental event. (JMB)

Choice and use of problem-solving strategies were monitored during a picture comparison task for 90 kindergarten, second and fourth grade boys and girls. (SB)

Examination of the effect of two linguistic factors on kindergarten through fourth-grade students' understanding of idioms indicated that the younger subjects better understood syntactically frozen idioms than those presented in various syntactic forms, while older subjects comprehended both kinds. (Author/CB)

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…

Three experiments investigated the possibility that adult age differences on block design tasks originate because of reduced efficiency with increased age in the cognitive processes associated with block manipulation. Older adults were substantially slower and less efficient than younger adults in performing tasks with minimized design…

Assessed the knowledge of print of 324 children aged 3, 4, and 5 years by means of a set of 20 cards containing commercial logos and signs. Analysis of individual responses resulted in seven common categories describing the behavior of children as they progressed to recognition of the function of print. (NH)
