Developmental theory has long emphasized the importance of linking perception, cognition, and action. Techniques designed to record the spatial and temporal characteristics of hand movements (i.e., "manual dynamics") present new opportunities to study the nature of these links across development by providing a window into how perceptual,…

When in pursuit of rewards, humans weigh the value of potential rewards against the amount of effort that is required to attain them. Although previous research has generally conceptualized this process as a deliberate calculation, recent work suggests that rudimentary mechanisms--operating without conscious intervention--play an important role as…

People tend to perceive immediate emotions as more intense than previous emotions. This "immediacy bias" in emotion perception occurred for exposure to emotional but not neutral stimuli (Study 1), when emotional stimuli were separated by both shorter (2 s; Studies 1 and 2) and longer (20 min; Studies 3, 4, and 5) delays, and for emotional…

The main purpose of the present research was to examine the strategies employed by undergraduate students in the solving of three-term series problems. (Editor)

Inhibited encoding is the basis of some accounts of repetition blindness--impaired report of the second occurrence of a repeated word in a rapidly presented word sequence. The author presents evidence for the claim that repetition effects arise from constructive processes of perception and memory that occur to some extent after the word sequence…

Some task variables that influence sentence coding, and the ways in which those influences appear to be manifested in performance were outlined. Trends in empirical data were examined as evidence for two classes of coding strategies. (Author/RK)

The technique of priming was used to study the nature of the mental representations generated by color names. (Editor)

The authors present 2 experiments that establish the presence of knowledge partitioning in perceptual categorization. Many participants learned to rely on a context cue, which did not predict category membership but identified partial boundaries, to gate independent partial categorization strategies. When participants partitioned their knowledge,…

This study investigated psychological effects of longer-range L-Dopa therapy in Parkinsonism. (Author)

Prepared as part of a larger work on human intelligence, this report examines basic attentional and perceptual contributions to intelligence. The report is organized into two sections: the first summarizes and evaluates research that has tried to uncover basic information processing skills that account for individual differences in intelligence;…

Evidence is reviewed which suggests that there may be little or no direct introspective access to higher order cognitive processes. It is proposed that when people attempt to report on their cognitive processes they do not do so on the basis of any true introspection. (Editor/RK)

The research literature suggests that children and adolescents suffering from anxiety disorders experience cognitive distortions that magnify their perceived level of threat in the environment. Of these distortions, an attentional bias toward threat-related information has received the most theoretical and empirical consideration. A large volume…

A theoretical framework which makes possible the correlation of grammatical meaning with the structure of sensory experience is explored. (RM)

Focusing on the psychological processing of audiovisual materials by learners, this chapter presents and analyzes recent research on human perception, its relation to memory, and how perception is best represented in an information processing model. Topics discussed include pictorial and verbal memory, information system capacity, filtering and…

Reviews recent research on information processing and decision making in orienteering. The main cognitive demands investigated were selection of relevant map information for route choice, comparison between map and terrain in map reading and in relocation, and quick awareness of mistakes. Presents a model of map reading based on results. Contains…
