Tachistoscope simulation package

A system of FORTRAN-callable subroutines is described that enable a PDP-11/20 computer to function as a multichannel tachistoscope. Features of the system include multiple display buffering, dynamic buffer allocation, control of character size and density, provisions for user-generated characters and symbols, and routines for recording of both vocal and buttonpress responses.     

NOVA SKED: A behavioral notation language for Data General minicomputers

A state notation language (NOVA SKED) for the experimental control and collection of data from operant behavior experiments by Data General NOVA series minicomputers is described. NOVA SKED is based on the SKED system written for the Digital Equipment Corporation PDP8 series of minicomputers. The NOVA SKED state notation syntax enables diagramming experimental procedures directly and precisely by the operant experimenter, who need not be familiar with computers. This syntax can then be compiled by the computer into programs that operate under the SKED run-time system (RTS). The SKED RTS operates in a timesharing mode that allows up to 16 experimental stations to function simultaneously and independently from each other. NOVA SKED is a “stand-alone” system that collects and stores data on digital magnetic tape.     

Individual differences in cognition: Relationship between verbal ability and memory for order

The crucial role of order information in language has led to the suggestion that psychometrically measured verbal ability may be related to memory for order. The literature pertaining to this hypothesis is briefly reviewed and various methodological difficulties discussed. The results of three experiments indicated that (a) order and item information may be retained separately; (b) verbal ability is related to the short-term recall of order; (c) verbal ability is unrelated to memory for order when testing involves recognition rather than recall; and (d) the relationship between verbal ability and memory for order is most pronounced when the originally presented order must be transformed at output (as in the “digits backward” task). An output process in which material is decoded and held in an output buffer until decoding is complete is viewed as the most likely locus of the verbal ability-memory for order relationship.     

Effects of expectancy of outcome on the reactivity of self-monitoring

The present study investigated the effects of subjects' outcome expectancy on self-monitoring of a clinically relevant behavior, overeating. In conjunction with self-monitoring of eating habits, subjects received either a positive expectancy of behavior change or no expectancy regarding change. While both self-monitoring groups achieved significantly greater weight loss than controls, subjects in the expectancy group demonstrated significantly greater weight loss than no-expectancy subjects. Possible factors accounting for the disparity in findings between this and previous self-monitoring investigations are discussed.     

Differential effects of personality on access to various long-term memory codes

Arousal, as indexed by personality measures, has been related to memory encoding, organization, and retrieval. In an attempt to investigate one of the component information-processing mechanisms underlying both encoding and retrieval, the effects of introversion-extraversion on performance in a simultaneous matching task was investigated. As predicted from earlier research, personality did not influence performance on a physical identity matching task but extraverts were faster than introverts in making taxonomic category matches (a semantic task). Somewhat unexpectedly, extraverts were also faster at making “homophone” identity matches. Arousal, then, appears to influence access to long-term memory codes of any type—a characteristic that may be reflected in tests of both encoding and retrieval.     

The status of training in school psychology and trends toward the future

A nation-wide survey was conducted in 1979 to collect information on graduate training in school psychology, including areas of program emphasis and the structure of field training and supervision. Results indicated that the vast majority of programs remain committed to emphasizing the direct service triad of psychoeducational assessment, school consultation, and behavioral intervention, but that two indirect service areas—research and program planning and evaluation—are gaining in training emphasis. It was also found that a very high percentage of programs employ a comprehensive practicum and internship experence, that most placements are in the public schools, and that considerable time is allotted for supervision.
