Twenty-seven 4-month-old infants heard a repetitive auditory rhythm, then viewed silent film of puppet opening/closing its mouth, either in the familiar rhythm or a novel rhythm. Results showed infants exposed to the novel condition watched the film longer than infants shown the familiar condition, providing evidence for auditory-visual transfer…

Explores McLuhan's intellectual connection and indebtedness to his fellow Canadian Harold Innis. Contrasts their distinguishing characteristics and contributions to communications media theory. (PD)

We examined short-term changes in younger and older adults' control beliefs. Participants completed measures of general and memory-specific competence and locus of control on 10 bi-monthly occasions. At each occasion, participants rated their control beliefs prior to and following completion of a battery of cognitive tasks. Exposure to the set of…

Second-generation cultural-historical activity theory, which drew its inspiration from Leont'ev's work, constituted an advance over Vygotsky's first-generation theory by explicitly articulating the dialectical relation between individual and collective. As part of an effort to develop third-generation-historical activity theory, I propose in this…

Children's observation of the given-new contract was tested with a task requiring children to provide novel, rather than known, information about an event to a listener. Study 1 revealed developmental differences in children's adherence to the contract: 4- and 5-year-olds showed better adherence to the contract than 3-year-olds. In Studies 2 and…

To investigate the development of children's knowledge of the intension and extension of four natural concepts (cup, scissors, money, and musical instrument), three questions were explored in an experiment involving one-hundred-and-twenty 3-, 5-, and 7-year-old children (40 children for each age group). Extension was measured in a verbal labeling…

Evaluates Heather Hemming's research project, "Reading as a Monitor in Writing" (this issue). Emphasizes the contribution this project makes to research methodology. Stresses Hemming's conclusion that the type of monitoring strategy used is not important, providing it is effective. (MM)

To explore possible age differences, the first experiment assessed speed and maintenance of alertness in 5-year-olds, 8-year-olds, and adults. The second study tested the hypothesis that developmental variation in processing speed observed in some studies was attributable in part to age differences in alerting processes. (MP)

A series of five experiments are reported which support the proposition that observers between three years of age and adulthood interpret physical causation primarily in terms of the concept of generative transmission rather than in terms of other well-known rules such as covariation, similarity, and temporal and spatial contiguity.

Finds that, among 214 Canadian college students, subjects with high test anxiety had significantly lower overall scores on the Wisconsin Card Sorting Test (WCST) and experienced greater cognitive interference during the test than subjects with low test anxiety. Groups did not vary significantly, however, on individual WCST variables. (SV)

Eight clients participated in interpersonal process recall interviews to review therapy sessions in which they explored problematic reactions. Grounded theory analysis of reports resulted in model of cognitive-affective operations characterizing clients' internal processes during sessions. Model's main categories were client operations and session…

The development of probability judgment is explained in terms of working memory, composed of four types of storage operations and three types of processing operations. Age changes in probability judgment were related to changes in frequency retrieval, which stem from changes in constraints on work-space capacity. (Author/RD)

This study is about engagement in adult literacy education. Engagement is mental effort focused on learning. It is important to understand how and why adult learners engage in literacy instruction because engagement is a precondition to learning progress. Researchers who study engagement conceive of it in different ways. Some focus on engagement…

This study investigated the effects of second language (L2) proficiency and task-induced cognitive workload on participants' speech production and retention of information in an environment designed to simulate the demands faced by pilots receiving instructions from air-traffic controllers. Three groups of 20 participants (one…

A series of studies focused on (1) the evolution of the notion of identity of objects among infants up to 15 months of age and (2) the changing rules by which this development may be understood. Six identity tasks were presented to 60 infants divided into five age groups: 5, 7, 9, 12, and 15 months. Two objects were used in all tasks. In the first…
