Three interactive tasks, increasing in the complexity of resource-directing reasoning demands on speaker/storyteller attribution of, and linguistic reference to, the thoughts and intentions of characters in narrative stimuli were performed by Japanese L1 speakers of English. Largely consistent with the claims of the Cognition Hypothesis, results…

Levels of independent variable(s) are often mixed within each block of trials rather than each level being presented in a separate block in research of various types. Two experiments involving tasks of a visual nature were conducted to demonstrate that such mixing can easily obscure the effects of principal interest. A target circle was projected…

This paper describes an approach to task analysis which seeks to identify potential sources of difficulty in the self-discovery of improved procedures by students who have been taught simpler procedures. The approach considers novices' procedures in terms of the changes needed to produce an expert procedure; the knowledge required to make those…

Phonemic awareness tasks are identified: sound-to-word matching, word-to-word matching, rhyme recognition, isolation segmentation, counting sounds, blending, deletion, and substitution. Methods for teaching segmentation and blending, the most cortical tasks, are discussed. (Author/CP)

Three problem-solving strategies--working backward from the unknown, forward from the given, and mixed--were applied to interrelated algebra equations. The mixed strategy was most popular and most efficient with grouped variables. Memory load or information-processing load differences among the strategies were evident. (CP)

Less is known about the effects of normal aging on speech output than other motor actions, because studies of communication integrity have focused on voice production and linguistic parameters rather than speech production characteristics. Studies investigating speech production in older adults have reported increased syllable duration (Slawinski,…

Categorization researchers typically present single objects to be categorized. But real-world categorization often involves object recognition within complex scenes. It is unknown how the processes of categorization stand up to visual complexity or why they fail facing it. The authors filled this research gap by blending the categorization and…

Two characteristics that determine problem difficulty--the nature of the move search space and its interaction with other aspects of the task--were investigated in experiments in which 26, 69, 42, and 42 community college students attempted to solve the Chinese Ring Puzzle. The origins and implications of difficulty are discussed. (SLD)

Describes a framework for examining the effects of the cognitive complexity of tasks on language production and learner perceptions of task difficulty, and for motivating sequencing decisions in task-based syllabuses. Results of a study of the relationship between task complexity, difficulty and production show that increasing the cognitive…

To test the hypothesis that level of neural complexity explain the relative level of performance and brain activity in autistic individuals, available behavioural, ERP and imaging findings related to the perception of increasingly complex auditory material under various processing tasks in autism were reviewed. Tasks involving simple material…

The Assessment of Basic Learning Abilities test (ABLA) is a useful tool for choosing appropriate training tasks for persons with developmental disabilities. This test assesses the ease or difficulty with which persons are able to learn six hierarchically positioned discrimination tasks. A visual-visual nonidentity matching prototype task was…

Discusses briefly some general problems in the development of taxonomic systems applicable to descriptions of human performance and tasks, describing some alternative approaches and provisional classification schemes, and reviewing some attempts to evaluate the utility and validity of these systems. (Author/JM)

The learning machine described in this paper acquires concepts representable as conjunctive forms of the predicate calculus and behaviors representable as productions (antecedent-consequent pairs of such conjunctive forms): these concepts and behavior rules are inferred from sequentially presented pairs of examples by an algorithm that is probably…

The study constitutes a preliminary investigation of several important factors in the design and implementation of adaptive training research. The effects of using various adaptive stepping criteria upon performance were studied. Comparison of adaptive and nonadaptive training techniques were also made. The tested hypotheses were that: (1) there…

Examines the relation between attention to target and context information and target recall in an incidental learning task for children and adults. Results support a distinction between context-interactive and context-independent situations and suggest that the attentional patterns that are efficient for memory may differ with the kind of…
