Purpose: Humans have a near-automatic tendency to entrain their motor actions to rhythms in the environment. Entrainment has been hypothesized to play an important role in processing naturalistic stimuli, such as speech and music, which have intrinsically rhythmic properties. Here, we studied two facets of entraining one's rhythmic motor actions…

Beaconing is a process in which the distance between a visual landmark and current position is reduced in order to return to a location. In contrast, dead reckoning is a process in which vestibular, kinesthetic and/or optic flow cues are utilized to update speed of movement, elapsed time of movement, and direction of movement to return to a…

Experts have a remarkable capability of locating, perceptually organizing, identifying, and categorizing objects in images specific to their domains of expertise. Eliciting and representing their visual strategies and some aspects of domain knowledge will benefit a wide range of studies and applications. For example, image understanding may be…

This paper offers an overview of research on infants' early behavior toward televised images, followed by an account of the development of "representational competence" with video. Several aspects of representation are involved in young children's understanding and use of video. From a very young age, children form mental representations of the…

Two experiments investigated 18-month-olds' understanding of the link between visual perception and emotion. Infants watched an adult perform actions on objects. An emoter then expressed neutral affect or anger toward the adult in response to the adult's actions. Subsequently, infants were given 20 s to interact with each object. In Experiment 1,…

The development of children's capacity to induce spatial relations between locations in a space was investigated in this study. The sample consisted of 60 children, 20 in each of three age groups: 3-4, 5-6, and 7-8 years of age. The children were trained to move one hand from a home base to each of three target positions. The positions were…

The purpose of this research project is to specify critical events within a person during linguistic processing. The experiments reported here cover such topics as the effects of increased reading rate on covert processes, covert behavior as a direct electro-myographic measure of mediating responses, enhancement of speech perception by…

Ten sighted adults were blindfolded and asked to find four objects in the open space of a room. A perimeter pattern, a gridlike search pattern, and a reference-point strategy were variably effective, indicating that different kinds of experience may result in different kinds of knowledge that are optimal for different spatial judgment tasks.…

Incomplete intersensory integration development in schizophrenic children appears to be an underlying source of symptom expression and formation which usually fails to improve with age. (SB)

A SYSTEMATIC EXPLORATION OF THE COGNITIVE PROCESSES INVOLVED IN THE PRODUCTION OF A DRAWING WAS CONDUCTED. A SITUATION WAS DESIGNED IN WHICH A SAMPLE GROUP OF ABOUT 30 ARTISTS COULD BE OBSERVED AT WORK. BEHAVIOR WAS RECORDED AND THE PROGRESS OF THEIR WORK PHOTOGRAPHED. OF THE BEHAVIORS OBSERVED, SIX WERE TAKEN TO REFLECT RELEVANT STAGES IN THE…

Two five-week test-retest reliability studies of a measure of the unit of perception of ongoing behavior were conducted. In the first, 25 females and 23 males segmented a 7-minute action sequence under fine-unit or gross-unit instructional sets. Number of units marked at first viewing correlated .87 with number of units at retest. Correlations…
