Hirt, Michael; And Others – Journal of Abnormal Psychology, 1977
The performance of hospitalized paranoid schizophrenics, nonparanoids, and hospitalized controls was compared on motor, perceptual, and cognitive tasks of increasing complexity. The data were examined within the context of comparing differential predictions made by input and central processing theories of information-processing deficit. (Editor)

Nelson, Keith E.; Earl, Nancy – Child Development, 1973
This study examined a category-induction'' manipulation which focused the attention of 40 preschoolers on categories through discussion and through spatial arrangement of items. This manipulation induced children's use of category questions. (ST)

Hawkins, Harold L.; And Others – 1978
Three experiments were undertaken to examine the processing limitations that underlie multiple task performance and, ultimately, to test the theory that there exists a time-sharing ability which is general and can be assessed through the simultaneous presentation of any two or more sufficiently demanding tasks. Subjects were males and/or females…

Henker, Barbara A.; Whalen, Carol K. – Proceedings, 80th Annual Convention, APA, 1972, 1972
The present study used a set of bimodal (auditory-visual) conflict designed specifically for the preschool child. The basic component was a match-to-sample sequence designed to reduce the often-found contaminating factors in studies with young children: failure to understand or remember instructions, inability to perform the indicator response, or…

Myer, Bayla Miller; O'Connell, Daniel C. – Journal of Experimental Psychology, 1972
Memory span of symbol strings decreased as string length or number of different symbols composing the strings increased. Recall of digit strings was a function of string length only. (Author)

Wells, Herbert – Journal of Experimental Psychology, 1972
Length of intertrial interval was found to be positively related to the efficiency of concept learning in a blank-trials task. (Author)

Simon, J. Richard; Pouraghabagher, A. Reza – Journal of Gerontology, 1978
Two experiments were conducted to determine the effect of aging on encoding and response selection stages of a choice reaction time task. Results suggested reducing stimulus discriminability may affect information processing prior to the encoding stage, but the encoding stage is the primary locus of the slowing which accompanied aging.

Derks, Peter L. – Journal of Experimental Psychology, 1972
The similarity match took longer than the identity match, and the difference in latency increased as the number of lines in the pattern increased. (Author)
