This study investigated the developmental patterns for 82 deaf individuals (9-19 years old) in field dependence, as measured by the Embedded Figures Test. A significant sex difference was found for these deaf subjects only at the age of 15, favoring males. The deaf subjects differed significantly from the hearing norm group only at ages 15 and 17.…

The Euclidean Traveling Salesperson Problem (E-TSP) is a useful task to study how humans optimize when faced with computational intractability. It has been found that humans are capable of finding high-quality solutions for E-TSP in a relatively short time and with seemingly little cognitive effort. This observation has led to two general…

One hundred and sixty subjects ages 7, 9, 11 and 21 years judged the standard Brentano form and a dot form of the illusion of 5 trials at 30 second intervals. (LLK)

This study was designed to analyze developmental differences in the rehearsal strategies of 60 subjects of three age groups. Data revealed significant age differences in recall. Fifth and eighth graders tended to repeat stimulus words immediately after presentation while adults tended to reenter items for additional rehearsal. (LLK)

The ordering of difficulty of logic principles and the age of acquisition for each were examined with 160 gifted children (20 each from ages 4 to 11). Five principles of class logic were explored: three orders of enthymemes, i.e., missing conclusion, missing minor premise, and missing major premise; and two additional third order enthymemes, i.e.,…

The present study was designed to determine whether previous experience with categorically related items would facilitate third and sixth grade children's recall of subsequent unrelated materials. Subjects were 24 children at each grade level. An additional aim was to see if such experience with taxonomic material would influence both the manner…

This study of children's memory was intended to: (1) extend a set of procedures used to study levels of processing in the memory of adults, and (2) study the development of the dynamic memory system unencumbered by developmentally influenced strategies in the areas of metamemory, encoding, organization and storage, and retrieval. Ninety-six…

Two experiments investigated the role of children's spontaneous conceptual "biases" in pictorial discrimination learning. The results suggested that such biases may serve either to facilitate or to interfere with discrimination learning. Moreover, in each experiment, age by treatment interactions revealed that in comparison to the behavior of…

Evaluates possible differences in the cognitive representations of semantic categories between children and adults independent of spontaneous memory skills. Response latencies on a classification task were compared for second, fourth, and sixth grades and college students. (Author/MP)

Compares the memorial consequences of orienting tasks which demand a high degree of information integration with those of tasks which demand a high degree of information selection. Subjects were 43 fifth grade children and 40 undergraduate students. (Author/MP)

Subjects aged 8, 10, 12, and 18 years participated in two visual search tasks. (Author/SB)

Two studies explored the hypothesis that young children perceive integrally some stimuli that older children perceive separably. In both experiments, kindergarten, second- and fifth-grade children were required to classify sets of stimuli that varied in size and brightness. (SB)

To test the comparative efficacy of a visual imagery associative learning strategy in younger and older children, second and sixth grade children were presented a list of paired associates (concrete nouns) either at a faster or slower rate, under either an instruction to generate an interactive image for the pairs or a no strategy, control…

Subjects were 72 first, third and fifth graders. Stimuli consisted of an initial set of 20 unrelated pictures, and a second set of 20 pictures which could be classified according to four superordinate categories. (MS)

It was hypothesized that slight modifications in word association test (WAT) instructions would have no discernible effect on the responses of college students, but would produce significantly different response hierarchies generated by young children. (Author/MS)
