Essential computing skills needed by psychology students seeking careers in business

This article describes some essential computer skills needed by psychology students seeking careers in business. It is suggested that students become familiar with computer software packages in the following areas: statistical analyses, wordprocessing, spreadsheets, data base managers, and graphics. Discussion is provided.Paper presented at the 57th Annual Convention of the Midwestern Psychological Association, Chicago, Illinois, May 1–3, 1985.     

Disruptive emotions and the measurement of irrationality

The purpose of the present study was to develop an alternative paradigm for measuring irrationality and conduct a preliminary reliability and validity analysis of a self-report scale so constructed. From considering some basic theoretical assumptions in Rational-Emotive Therapy (RET), anemotive paradigm for item-construction was formulated and utilized to develop a 12-item self-report scale for measuring irrationality (SVO-12). A different scale (SVC-12), based on acontent approach, was also developed. These two irrationality scales and a scale for measuring psychopathology were then administered to a group of 199 undergraduate students. Statistical analyses provided empirical support for the reliability and validity of both approaches. Of the two irrationality scales in question, however, the one based on the emotive paradigm (SVO-12) seem to be the most promising.

Data transfer concepts and strategies in a psychological research environment

In this paper, we discuss the importance and problems of data transfer in psychological research environments. Discussion includes how simple text file transfer systems meet researchers’ needs. The systems’ shortcomings are also analyzed. Strategies for customizing systems, using pre-prepared software packages, point-to-point systems, and “networked” systems, are carefully analyzed.     

A simple infrared photocell device and its interface to an Apple computer

This paper describes a simple infrared photocell circuit that is inexpensive and easy to construct. The light source and detector are housed inexpensively and are focused so the light and detector may be separated over significant distances. The circuit may be used in a variety of conditions, including total darkness and bright fluorescent lighting, without having to readjust or recalibrate the circuitry. Output from the circuit may be used to drive other transistors or electromechanical relays. With minimal additional circuitry and hardware the signal may be interfaced with an Apple computer.     

RSCORE-J: Pooled rating-method data: A computer program for analyzing pooled ROC curves

RSCORE-J, a computer program for a signal-detection analysis of pooled rating-method data, is listed and described. RSCORE-J computes jackknife estimates of ROC parameters and their standard errors from rating-method data pooled over a group of observers.     

Amiga 1000 hardware timing and reaction-time key interfacing

A method of hardware reaction timing with millisecond accuracy, using one of the Amiga’s CIA 8520 chips, is described. The registers of this chip can be set to enable cascaded timing that functions independently of the CPU and, thereby, avoids the problems of software timing in a multitasking environment. In addition, the interfacing of a pair of reaction-time keys to one of the Amiga’s game controller connectors and a program for polling this port for keypresses are described.     

Blood pressure responses to hypnotic and nonhypnotic suggestions in normotensive subjects

Forty normotensive subjects participated on a voluntary basis in a study designed to compare the effect of suggestions on blood pressure (BP). Two experimental groups received suggestions presumed to be specific in lowering or raising BP after simple relaxation (relaxation group) or hypnotic induction (hypnotic group). A control group was used to record the BP changes over time. The time variable was significant for both systolic (SBP) and diastolic blood pressure (DBP). Induction procedures (hypnosis or relaxation) resulted in significant decreases in DBP in both experimental groups. In the control group there was a significant decrease in SBP. A specific suggestion to increase the BP resulted only in DBP increase in the hypnotic group. This group also gave an increase of both SBP and DBP over the entire experiment, whereas the relaxation group resulted in a significant decrease in SBP. There was no significant group variable, indicating no differences between the groups. Further research is needed to enable firm conclusions of the effect of suggestions on BP.
