Ss decided whether dichotically presented consonant or vowel phonemes were “same” or “different” in a reaction time (RT) task. Results indicated that “different” responses were made on the basis of a serial, self-terminating scan of distinctive feature differences between phonemes. “Same” responses were considered too fast to be accounted for by this process and were discussed as a separate parallel process. Recognition of dichotically presented syllables appears to involve a third process in which phonemes are also identified in terms of their distinctive features. 相似文献

The role of auditory and visual factors in short-term recall and recognition performance was evaluated. Auditory similarity, but not visual similarity, was found to be predictive of the probability of a correct response and response confidence for both types of tests. The results were interpreted as support for a single-trace model of recall and recognition performance. 相似文献

In Sternberg's memory scan paradigm, subjects were required to scan for category membership or physical identity. In Experiment I, the scan rate when checking for either type of relationship at the same time was less than the sum of the scan rates when checking for either relationship separately. In Experiment II, presenting memory sets consisting of items from a single category affected the category scan function but not the physical scan function. The results were interpreted as evidence for the capacity to conduct parallel scans of independent memory encodings when retrieving remembered information. 相似文献

Analog signals, generated by BASIC R/T plot commands, are used to control a modular interface system. The interface system converts the analog signals to either BCD or decimal formulated pulses which are used to drive up to 10 relays. The system is coupled to a LAB 8/E minicomputer that permits precise timing of intersignal intervals as well as the simultaneous recording of many response variables. 相似文献

SKED is a minicomputer operating system based on the functional use of state notation as a programming language. An overall view of the operating system, state notation, and the hardware necessary to simultaneously control as many as 12 experimental stations is provided. 相似文献

This report describes the design and operation of a second-generation motor rhythm analysis system (MRAS). The system enables quantification of spatial and temporal characteristics of movements performed in synchronization with audio-visual rhythmic stimuli. The MRAS also provides for assessment of preferred tempo in performance of repetitive movements. In addition to discussing the rationale for developing the system, consideration is given to procedures for its utilization in research regarding motor rhythm and preferred tempo. 相似文献

A brief historical review of research on the use of computers in mental health service delivery is presented. The computer-assisted psychiatric assessment project (PAU) at the Salt Lake City VA Hospital is briefly described in the perspective of previous research. It is noted that the initial design for the PAU was deficient in the development of a computer generated reporting scheme which is totally acceptable to clinicians. Two conceptual innovations, interventionally relevant reporting and retrofit programming, are introduced. These are described as providing solutions to the problem of obtaining clinician acceptance of computer-generated assessment reports. Pilot research on the use of these concepts is presented. 相似文献
