Interpretation of canonical analysis: Rotated vs. unrotated solutions

Orthogonal rotation of canonical variates is shown to preserve the major properties of the canonical solution and may increase its interpretability.     

A monte carlo evaluation of interactive multidimensional scaling

Interactive Scaling with Individual Subjects (ISIS) developed by Young & Cliff [1972], is a method involving interaction between subject and computer in real time to determine which judgments made by the subject are critical to the definition of a dimensional structure. The procedure is based on the mathematical fact that it is possible to define a space ofR dimensions in terms of only the interpoint distances between all stimuli being scaled and a subset of (R+1) of these stimuli. For errorless judgments, any subset of (R + 1) stimuli is appropriate. However, fallible data require that the subset consist of stimuli that are maximally dissimilar, and the ISIS procedure is designed to obtain such an optimum subset (a basis).This research evaluates a modified version of ISIS with respect to (a) a metric MDS analysis based on all possible pairs of the stimuli, and (b) a metric MDS analysis based on a subset of one-third of the possible pairs, or about the same number as that required by ISIS. Results show that the ISIS method achieves better fit than (b) at low error levels, and may also achieve better fit than (b) at higher error levels if the size of the basis is increased. The more stimuli in the basis the more indices of fit approach those of (a).A new method of introducing error in MDS studies is used in the evaluation.This research is based in part on the doctoral dissertation of the first author, and was supported by research grant MH-16474 from the National Institute of Mental Health, Public Health Service.     

An analysis of double-function lists

Double-function list acquisition was analyzed in three experiments which used mixed-list designs and forced-choice recognition tests. Findings showed that specific associative interference occurred both during learning and performance phases, that its source was limited to the immediate backward associate during the learning phase, but that it also involved items further removed in both the forward and backward directions during the performance phase, probably by way of mediated chaining.     

THE CHANGING CRITERION DESIGN

This article describes and illustrates with two case studies a relatively novel form of the multiple-baseline design called the changing criterion design. It also presents the design's formal requirements, and suggests target behaviors and circumstances for which the design might be useful.     

Balance,agreement, and attraction in hypothetical social situations

Sixty subjects rated hypothetical P-O-X situations involving two persons and an unspecified but important “thing” for pleasantness, tension, and consistency. The situations varied in terms of whether P and O liked or disliked each other and whether P and O agreed or disagreed regarding X. Half of the subjects rated eight situations used by Gutman and Knox (Journal of Personality and Social Psychology, 1972, 24, 351–357) in which a unit relation was induced between P and O by describing them as necessarily having to continue interacting with one another in the future. The other half of the subjects rated situations that were identical to those of the unit condition, except that stipulation of continued interaction was omitted, so that no unit relation was specifically induced. Results showed that preferences for agreement and attraction were stronger for pleasantness and tension ratings than for consistency ratings, while the preference for balance was stronger for consistency ratings than for pleasantness and tension ratings. When no unit relation was specified, the balance preference increased, whereas the attraction preference decreased. Moreover, the effect of attraction decreased more from the unit to the no unit condition for pleasantness than for tension ratings and more for tension than for consistency ratings. The results underscore the need to consider the influence of both the described characteristics of hypothetical social situations and the type of dependent measure employed on the weighting of preferences for balance, agreement, and attraction.     

VALUE SYSTEMS OF STUDENTS IN PAPUA NEW GUINEA AND AUSTRALIA

The Rokeach Value Survey was administered to 12 groups of indigenous respondents fluent in the English language and enrolled in tertiary institutions and training programmes in Papua New Guinea (over 1,100 subjects). Average value systems of these respondents were compared with those of three Australian student groups (secondary and tertiary). Marked differences were found in the relative importance assigned to particular values. Values assigned relatively high importance by the Papua New Guinea groups were discussed in relation to lower-order safety and security needs that may become salient in a developing country, and in terms of the traditional culture and the history of Papua New Guinea, especially the missionary influence, the extended family and wantok (”one-talk”) systems, possible expatriate influence on occupational roles, and present concern with emerging nationhood. Values assigned relatively high importance by the Australian groups were discussed in relation to higher-order needs that might become prepotent in a more affluent society. Factor analyses indicated that all 12 groups in Papua New Guinea were fairly similar in their average value systems.     

Facial attractiveness and juvenile delinquency among black and white offenders

Facial pictures of black and white delinquents were significantly less attractive than pictures of corresponding groups of high school students, as judged by same-race raters. Significant differences were found among the white delinquents, but not among the black, for Quay's four behavioral dimensions of delinquency. Black delinquents were significantly darker in skin color than the black high school students, and lightness of skin color was positively correlated with physical attractiveness ratings made by both black and white raters, indicating that neither race has yet assimilated the saying black is beautiful. This and other evidence suggest that facial attractiveness may be causal in delinquency.These studies were conducted with the cooperation of the staff of the Robert F. Kennedy Youth Center, Federal Bureau of Prisons, U.S. Department of Justice.

The portion of this paper dealing with the white offenders was presented at the meeting of the Eastern Psychological Association, Boston, Massachusetts, April 1972.The authors would like to thank Hayne W.

A system for accurately measuring articulatory durations which is not reset by any included silent periods

A device is described that accurately measures duration of phonation or articulation without being reset by intervening silent periods or pauses, which may be within the range of 10 to 1,000 msec. Thus, it is possible to time the overall duration of single sounds, syllables, single or multiple words, even though periods of silence are included. Input can be direct or recorded, the ancilliaries being a voice-operated switch and a chronoscope.     

Pitfalls in pastoral counseling (in the overdependency relationship)

Summary In this discussion of pitfalls in pastoral counseling, it has been seen that it is when the pastor comes into repeated close emotional contact with his people in the counseling relationship that he becomes exposed to certain anti-therapeutic procedures.One of the main pitfalls is that of unconsciously, because of his helping professional bent, fostering overdependency in his counselees. Some of the major signs of the development of an overdependency relationship are seen to be the attempts on the part of the counselee to seek advice, to seek extra appointments or telephone counsel, to attempt to prolong individual sessions longer than the allotted time, and to attempt to perpetuate the duration of the counseling process beyond the immediate conflictual situation.Some interpretation of these neurotic appeals by the counselee are offered. It is hoped that the early recognition of at least some of the signs of a developing overdependency relationship by the pastoral counselor will enable him to avoid the pitfall of unconsciously fostering such a relationship, and to deal with such individuals in a more therapeutic fashion.Dr. Desrosiers has served, for some twenty years, as chaplain in a mental hospital, parish minister, physician, as well as psychiatrist.
