Correction of errors in scientific research

Four ways to reduce scientific errors are by tests of equipment and programs, examination of results, peer review, and replication. This article describes various types of errors that may occur and procedures available for the prevention and correction of both unintentional and intentional errors in experiments that use computer programs to generate the stimuli, record the responses, or analyze the data. We describe a case study of a particular experiment that produced a result that has been found to be erroneous. The case study provides additional evidence of the essential importance of replication for the identification and elimination of scientific error.     

THE PHYSICS OF DAVID BOHM AND ITS RELEVANCE TO PHILOSOPHY AND THEOLOGY

Abstract. The purpose of this paper is to analyze David Bohm's work in terms of physics, philosophy, and theology. First, I discuss the development of Bohm's thought since 1951. Then, using the methodology of Imre Lakatos, I evaluate the scientific status of his research program. Next, I explore the philosophical dimensions of Bohm's views in which realist and idealist, monist and dualist, contingent and determinist outlooks occur in creative tension. Finally, I suggest ways in which Bohm's ideas are relevant to theology through concepts of God and cosmos, beauty and purpose, grace and free will, church, self and evil.

The entire universe is basically a single, indivisible…but flexible and ever changing, unit (Bohm 1951, 140).

     

Attitudinal qualities relating to the strength of the attitude-behavior relationship

A study was conducted to examine the relation between each of several attitudinal qualities and attitude-behavior consistency. Subjects' attitudes toward volunterring to participate in psychological research were assessed. The number of experiments in which each subject volunteered to participate was employed as the measure of behavior. Attitude-behavior consistency was significantly related to (1) the amount of direct experience upon which the subject's attitude was based (specifically, the number of experiments in which the subject had previously participated), (2) the degree of certainty with which the attitude was held, and (3) how well-defined the subject's attitude was, as measured by the width of his latitude of rejection. These three attitudinal qualities were significantly intercorrelated, suggesting that direct experience with an attitude object may produce an attitude that is both better defined and more confidently held than an attitude formed through more indirect means.     

From the word to the conversation: Paradigms and psychology in German protestant pastoral thought

Under steady pressure from ordinary pastoral practice German Protestantism gradually made proclamatory pastoral care more responsive to human need and more adequate to human complexity. In doing so it drew heavily from psychology, but the very refinements helped obscure its original intent. For that and other reasons it came into crisis and was replaced by therapeutic pastoral care, which now dominates German pastoral thought and practice. Each of these paradigms of pastoral work reflected in its own way on the theological aspects of pastoral care, producing quite different theologies of pastoral care and employing psychology in that process in quite different ways.Dr. Burck is Assistant Professor of Religion and Health and Chaplain-Supervisor at Rush-Presbyterian-St. Luke's Medical Center, 1753 W.

Effects of attack and uncontrollable noise on aggression

After being either attacked or treated in a more neutral manner by an experimental confederate, male subjects shocked the confederate while being stimulated by loud noise. Among previously attacked subjects, possession of control over offset of the noise led to the delivery of shocks significantly shorter in duration than those given by subjects who did not have control. Mere predictability of noise offset did not have the same effect. Subjects who could control the noise did not differ from those who heard no noise with respect to the duration of shocks given. Noise had no effect on shock duration among nonattacked subjects. In a follow-up study subjects who were given bogus information that they were aroused by noise were less punitive toward an attacking confederate than subjects given no such information. The overall conclusion is that noise facilitates aggression in subjects who have been instigated to aggress to the degree that noise-produced arousal is misattributed to the instigating stimulus.     

The advantages of 16-bit microcomputers

Microcomputers have great applicability for psychological laboratories. While it is usual to limit discussions of microcomputers to 8-bit equipment, 16-bit machines have several advantages. In many situations, these systems prove to be more efficient and cost effective.     

Memory for movement: Interaction of location and distance cues and imagery ability

The present experiments examined the role of imagery ability in recall of either the terminal location or the distance of a preselected horizontal linear movement following changes in the recall starting position. Subjects were selected on the basis of their scores on a shortened version of the Betts Questionnaire upon Mental Imagery (Betts Q.M.I., Sheehan 1967). Both high and low imagers were assigned to one of four groups, HIL, LIL, HID, LID, the last letter indicating the movement cue (terminal location or distance moved) to be recalled. Recall of the appropriate movement cue from one of four new recall starting positions occurred after either a 5-sec or 30-sec unfilled retention interval. Analysis of constant error indicated all groups were unable to recall the specified movement cue independent of the other source of information, even when subjects were given explicit instructions to utilise an imagery strategy. The data corroborate our earlier findings that memory for self paced movements is based on an interaction of location and distance cues derived from the criterion movement.
