Previous research indicates that infants generalize syntactic-like structures to novel exemplars in a way that has been characterized as abstract and algebraic (Marcus et al., 1999). Infants appear to learn and generalize from speech more successfully than from nonspeech stimuli (Marcus, Fernandes, & Johnson, 2007). In this series of experiments,…

Wikis as shared digital artifacts may enable users to participate in processes of knowledge building. To what extent and with which quality knowledge building can take place is assumed to depend on the interrelation between people's prior knowledge and the information available in a wiki. In two experimental studies we examined the impact on…

In three experiments, subjects listened to a taped lecture on the topic of exposure meters for 35-mm cameras and were tested after one, two, or three presentations. Results suggest that repetition produces both a quantitative increase in amount learned and a qualitative change in the reader's processing strategy. (Author/LMO)

Autonomously developing organisms face several challenges when learning reaching movements. First, motor control is learned unsupervised or self-supervised. Second, knowledge of sensorimotor contingencies is acquired in contexts in which action consequences unfold in time. Third, motor redundancies must be resolved. To solve all 3 of these…

The learning productivity approach to higher education attempts to gain productivity, not so much by reducing or cheapening inputs but by enhancing higher education's major output: student learning. In the learning productivity perspective, the principal problem is in teaching and learning inefficiencies such as excessive nonlearning time,…

Investigated 7-month olds' ability to relate vowel sounds with objects when intersensory redundancy was present versus absent. Found that infants detected a mismatch in the vowel-object pairs in the moving-synchronous condition but not in the still or moving-asynchronous condition, demonstrating that temporal synchrony between vocalizations and…

People behave as if they know the structure of their environment. Because people rarely study that structure explicitly, several theorists have postulated an implicit learning system that abstracts that structure automatically. An alternative view is that people respond to local structure that derives from global structure. Measures are developed…

Reviews multichannel learning research to find the best ways to combine audio and video in television to improve learning, and summarizes the research findings into principles for instructional television production. Highlights include the effects of redundancy on learning and on audience attention, message clarity, and problems in instructional…

Three experiments assessed the intersensory redundancy hypothesis in early infancy. Findings indicated that habituation to a bimodal rhythm resulted in discrimination of a novel rhythm, whereas habituation to the same rhythm presented unimodally resulted in no evidence of discrimination. Temporal synchrony between the bimodal auditory and visual…

Reviews theoretical arguments from a longitudinal study of 1 Dutch child (age 3;8.13 at start) for considering production as a source of input for analysis and presents empirical evidence supporting the output-as-input hypothesis for the blending of the Dutch words "wats" and "iets." Evidence suggests the child analyzed his own…
