Difficulty levels of 168 randomly generated multiplication problems were obtained by testing 238 fifth-graders. Variables concerning the number of operations, digits carried, and magnitude of the digits were defined, and a least-squares procedure was used to construct structural models accounting for 60-70 per cent of observed problem difficulty…

The Elaboration Theory of Instruction is an alternative to organizing instruction in terms of a hierarchical task analysis. The hierarchical organization results in an instructional sequence that begins with highly fragmented, small pieces of the subject-matter content, which many educators have found to be demotivating. The elaboration theory…

Presents a study of preschoolers' imitation of a model's irrelevant hand gestures while performing easy and difficult tasks. (BD/BR)

Undergraduate judges were assigned to groups that differed in information-processing loads. Correct observations decreased and reports of illusory correlation increased as the information-processing load increased. (Author)

Presents the research findings of an empirical study conducted in Finnish governmental organizations on task complexity and information-seeking activities in real-life work tasks. Focuses on the relationship between information types and source use, and the effects of task complexity on that relationship. (Author/LRW)

To investigate students' self-monitoring practice and effects of educational level and task importance on self-monitoring, 510 students, varying in educational level from elementary through graduate school, reported the self-monitoring strategies they employed in three learning situations with different levels of task importance. The study…

Comments on analysis of attention tasks in Attention Deficit Hyperactivity Disorder (ADHD) provided by Wilding (2005)points out that whereas many regulatory functions, including alertness or arousal, appear to be impaired in ADHD, demonstrating basic attention deficits in selection or orienting functions in the disorder has proven difficult. Yet…

Performance assessments have become the norm for evaluating language learners' writing abilities in international examinations of English proficiency. Two aspects of these assessments are usually systematically varied: test takers respond to different prompts, and their responses are read by different raters. This raises the possibility of undue…

Reviews assumptions underlying approaches to research into speaking task difficulty and questions the view that test scores always vary with task conditions or discourse variation. Offers a new approach to defining task difficulty in terms of the interaction between pragmatic task features and first language cultural background. Results of a study…

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…

Previous studies have shown inconsistent results concerning bilinguals' use of gestures to compensate for reduced proficiency in their second language (L2). These results could be because of differing task demands. In this study, we asked 16 intermediate English L2 speakers (whose first language [L1] was Chinese) to watch a story and tell it back…

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…

The difficulty of four binary conceptual rules (conjunctive, disjunctive, conditional, and biconditional) was assessed using the rule-learning paradigm in a variety of stimulus populations. (Editor)

This study puts the Cognition Hypothesis (Robinson 2005) to the test with respect to its predictions of the effects of changes in task complexity ([plus or minus] few elements) and task condition ([plus or minus] monologic) on L2 performance. 44 learners of Dutch performed both a simple and a complex oral task in either a monologic or a dialogic…

This study attempted to explore the influence of causal elements (ability, effort, task difficulty, and luck) as the strongest elements of locus of control predicting students' academic achievement satisfaction among foreign students. Based on locus of control scale invented by Rotter (1966), the findings obtained from 210 foreign students in…
