Taming the Heathkit-Votrax speech synthesizer

Three inexpensive text-to-speech synthesizers are described, intelligibility data from a pilot experiment are reported, and software is offered that has been written to facilitate the phonemic programming of the Heathkit-Votrax synthesizer.     

A Commodore 64-based interface system for the operant laboratory

A system of interfaces for the Commodore 64 (C-64) microcomputer for use in the operant laboratory is described. This system frees the experimenter from limitations on the number of I/O lines available on the user port of the C-64 and offers the control of operant chambers for a low cost. Subroutines in machine code to control the interfaces, offering millisecond timing of external events, are presented. A sample BASIC program demonstrates how the subroutines are called from BASIC to run a simple discrimination experiment.     

Negative priming insame-different matching: Further evidence for a central locus of inhibition

Responses to recently ignored information may be slower or less accurate than responses to information not recently encountered. Such negative priming effects imply that the mechanism of selective attention operates on unattended, as well as attended, information. In the present experiment, subjects judged the second and fourth letters of five-letter strings (e.g., BABAB) as “same” or “different.” Responses were slower when a target letter was identical to the distractors presented in the immediately preceding trial. This effect did not depend on which response was required on the current or preceding trial. The results suggest that ignored information is functionally disconnected from the response system as a whole, rather than from a specific response.     

Tachistoscopic exposure of real objects for measurement of reaction time and movement time

In this paper, we describe an apparatus for measuring reaction times and movement times involved in reaching for real objects. Subjects view an object through a liquid crystal window, which serves as a shutter that can be made clear or opaque quickly (10 msec from opaque to clear, 30 msec from clear to opaque). The subject’s hand rests on a microswitch-equipped home key, and the object sits on a force-sensitive platform so that initiation of reach and time of contact with the object can be marked accurately. The apparatus interfaces with an IBM PC/AT through a digital I/O parallel port, so that reaction times and movement times are recorded automatically.     

Arousal and paired-associate learning

Walker and Tarte (1963) postulate that at short retention intervals high arousal paired-associates are reproduced more poorly than low arousal items. Walker and colleagues believe that this hypothesis is confirmed by their paired-associate learning studies. However, results of these paired-associate learning studies are position confounded artifacts. Better recall of low arousal items at short-term retention is caused by the coincidence of the recency effect and low arousal at the end of the trial. When these position effects are controlled there is no action decrement for the high arousal paired-associates. To test this assumption, the Kleinsmith and Kaplan study (1963) was replicated and two other variations were conducted. In these three studies with 76 subjects, which were tested at two minutes or 1 week, the action decrement occurs only when the two position effects coincide.

Affective responses to seeing oneself for the first time on unedited videotape

Despite the growing popularity of watching oneself on videotape, little systematic research has been conducted determine viewers' affective responses to video replay. This study addresses the question: what affective responses do women have when they view themselves for the first time on unedited videotape, in comparison to their responses when they view a peer or nature scenes on videotape? Affective responses were measured in three ways: self-report, physiological, and behavioral. Subjects who viewed themselves reported more negative feelings and anxiety, and smiled more frequently than subjects who watched another person or nature scenes on video. Subjects with high private self-consciousness had higher mean arterial blood pressures when viewing themselves than did subjects with low private self-consciousness. Overall, the implications for seeing oneself on video point to potential embarrassment but generally moderate effects.     

Willingness to Seek Help as a Function of Self-Disclosure and Problem Severity

In this study the authors examined the effects of problem severity, amount of self-disclosure, and self-disclosure flexibility on willingness to seek help for a problem. The participants were 101 midwestern university students enrolled in an introductory psychology course who had not had previous counseling experience. The participants completed the Jourard Self-Disclosure Questionnaire (SDQ), the Chelune Self-Disclosure Situations Survey (SDSS), and responded to questions after reading a scenario depicting a personal problem of either high or low severity. The results indicated that the factors that predicted the greatest amount of variance in willingness to seek help were the interaction of problem severity with willingness to self-disclose to a counselor, followed by problem severity; no gender differences were found. Implications for counseling and further research are discussed.     

Ethical Issues in Consultation,Associate Professor and Director

Consulting relationships differ from traditional counseling and psychotherapeutic relationships in several fundamental ways. These differences require special consideration in evaluating ethical questions and conflicts, identifying ethical parameters within any given situation, and using existing ethical guidelines in determining appropriate courses of action. Currently, formal guidelines specific to the practice of consultation are not available, and existing codes of ethics for the helping professions provide only limited guidance for consultation practice. Consequently, consultants bear a heavy personal responsibility for the consequences of their professional decisions and actions. In this article the author reviews several important ethical issues relevant to consultation and examines their implications for consultation practice.
