A total of 14 psychotic children with a mean age of nine years, two months, and 14 normal children having a mean age of six years, four months, were compared in terms of structural level and functional abilities on classification and seriation tasks. (Author/RH)

Findings highlight a general consideration for developmental research: namely, whether CA or MA is the more appropriate developmental parameter. (Authors)

We present a detailed process theory of the moment-by-moment working-memory retrievals and associated control structure that subserve sentence comprehension. The theory is derived from the application of independently motivated principles of memory and cognitive skill to the specialized task of sentence parsing. The resulting theory construes…

Structure was imposed on a tapping task by requiring participants to reproduce sequences of responses to icons organised in spatial clusters. A first experiment featured sequences either segregated or not segregated by clusters. Accuracy was higher for sequences segregated by clusters. Moreover, inter-response times were longer at cluster…

The Name Game activity that raises challenging mathematical questions is used to explore random permutations. A permutation of a set is an arrangement of the elements in some order.

The word length effect has been a central feature of theorising about immediate memory. The notion that short-term memory traces rapidly decay unless refreshed by rehearsal is based primarily upon the finding that serial recall for short words is better than that for long words. The decay account of the word length effect has come under pressure…

This commentary on the article by B. Gawronski and G. V. Bodenhausen (see record 2006-10465-003) highlights the strengths of the associative-propositional evaluation model. It then describes problems in proposing a qualitative separation between propositional and associative processes. Propositional processes are instead described as associative.…

When pictures and words are presented serially in an explicit memory task, recall of the pictures is superior. While this effect is well established in the adult population, little is known of the development of this picture-superiority effect in typical development. This task was administered to 80 participants from middle childhood to…

A study was made primarily to investigate attitudes of preschool children toward older and younger people. In addition, the age discrimination ability of preschool children was assessed, and the possible relationship of this ability to performance on a seriation task was explored. Quantity and quality of each child's contact with adults over 60…

To evaluate the hypothesis that memories are related to operative levels, children were shown pictures involving seriation, horizontality, and verticality and were asked to reproduce them 1 week and 5 months later. Although memories and operative levels did correlate, the relations were quantitatively weak and were undermined by serious…

THE VERBAL ORGANIZATION RELEVANT TO SERIAL LEARNING WAS STUDIED. NINETY-SIX FOURTH AND FIFTH GRADERS WERE REQUIRED TO LEARN THE ORDER OF ONE LIST OF 14 FAMILIAR NOUNS. THE CONDITIONS OF THE SERIAL TASK WERE PHRASE CONTROL, SENTENCE CONTROL, AND NOUN CONTROL. THE DEPENDENT VARIABLE WAS THE NUMBER OF CORRECT RESPONSES. A REPEATED MEASURES ANALYSIS…
