The data from this study support the hypothesis that the encoding of a letter, as well as operations associated with responding, requires attention in the sense of processing capacity. (Author)

The purpose of this experiment was to determine whether two dimensions of a single auditory stimulus are processed as competing channels of information, and if they are, whether S can selectively attend to one dimension specified at the beginning of a trial. (Author)

This article describes one experiment which tests a prediction from their explanation and another experiment which attempts to measure directly the amount of unlearning and spontaneous recovery-more generally, the availability-of competing responses. (Author)

Normal and retarded children's use of color, number, length and continuous quantity as attributes of identification was assessed by presenting them with contrived changes in three properties. Surprise and correct memory responses for color preceded those to number, which preceded logical verbal responses to a conventional number-conservation task.…

Study was designed to investigate the effects of color cues and of subject-employed strategies in the development of selective attention in a short-term memory task. (Authors)

The purpose of the present paper was to examine and describe the early state of the art of the development of theories of retrieval, one of the important objectives of research on memory. (Author/RK)

Deficits in position memory particularly seemed to be the major distinguishing variable between normals and retardates in the present study. (Authors)
