The objective of this study is to summarize Israeli children's information and interpretation of the 1973 Middle East War while the intense fighting was in process. (Author/KM)

Effects on the event-related potential (ERP) waveform of differences in stimuli (task difficulty) and threshold were studied with 35 undergraduates performing a visual inspection time task and 30 performing a pitch discrimination task. In both tasks, ERP differences related to threshold were temporally localized differences in waveform shape. (SLD)

Examined gaze aversion in 5- and 8-year-olds when answering verbal reasoning and arithmetic questions of varying difficulty. Found that older children increase gaze aversion from the face of the adult questioner in response to both verbal and arithmetic difficult questions. Young children responded less consistently to cognitive difficulty.…

Findings indicated that: (1) 10- and 13-year-olds had difficulty accepting contrary-to-fact premises as a basis for reasoning; (2) 15- and 18-year-olds found reasoning correctly more difficult with contrary-to-fact premises; and (3) among 5- and 7-year-olds, a fantasy context decreased the extent to which empirical knowledge interfered with…

This paper describes an exercise in determining the cognitive difficulty of the assessment tasks in six computing courses within an Information Technology (IT) degree, importing Bloom's taxonomy from the field of educational psychology as an analytical framework. Three of the six courses comprise a Programming stream and three a Data…

The purpose of this study was to examine the instructional effectiveness of different levels of chunking (simple visual/text and complex visual/text), different forms of feedback (item-by-item feedback, end-of-test feedback and no feedback), and use of instructional gaming (game and no game) in complementing animated programmed instruction on a…

This paper reports on a study on the relationship between cognitive task complexity and linguistic performance in L2 writing. In the study, two models proposed to explain the influence of cognitive task complexity on linguistic performance in L2 are tested and compared: Skehan and Foster's Limited Attentional Capacity Model (Skehan, 1998; Skehan…

Results support the general conclusion that the disposition to respond in either a reflective or impulsive fashion influences the problem-solving efficiency and strategy behavior of elementary school children. The relative impact of cognitive style on problem solving varied with developmental level and the type of problem solved. (Author/BJG)

This study was designed to examine the processes underlying developmental changes in children's (1) use of combinatorial strategy, and (2) comprehension of conjunctive and disjunctive propositional relationships. A total of 108 children from third, sixth and eighth grades participated in this study. Each child was administered three tasks…

Combinatorial and implicative operations were studied with tasks which eliminated many complexities found in Piagetian tasks, but which did not alter the logical strategies required by Piaget's task. Task difficulty in relation to information-processing demands of tasks and processing capacities of subjects at three age levels (8.0-10.1 and…

A battery of 10 intelligence tests was administered to 22 subjects under standard conditions. After the testing session the degree of perceived similarity between 5 tests of the battery was to be estimated with regard to: (1) the kind of intellectual activity required by the tests, and (b) difficulty. Estimated qualitative similarity, according to…

The present study, and the development of the instrument for the measurement of conservation, arose in the context of wishing to demonstrate finely discriminating individual differences in this cognitive capacity. (Author)
