Part and bipartial canonical correlation analysis

Extending the definitions of part and bipartial correlation to sets of variates, the notion of part and bipartial canonical correlation analysis are developed and illustrated.     

The role of locus of control of reinforcement in interpersonal attraction

The purpose of the present study was to examine initial interpersonal attraction as a function of locus of control orientation. Subjects, previously tested for internality and externality, listened to a tape of an alleged stranger of the same age and sex as the subject. In reality the tapes were prepared to be either primarily internal or external in emphasis. Subjects were then asked to make some judgments about the supposed stranger. Among these judgments was the degree of attraction felt toward the individual on the tape. It was hypothesized that similarity of locus of control orientation between a subject and a stranger would lead to greater initial attraction than would a complementary locus of control orientation. Contrary to prediction, the results showed that both internal and external subjects were significantly more attracted to an internal stranger than to an external stranger. These results were discussed within an interpersonal attraction framework which suggested the need for a two-factor theory as the basis for interpersonal attraction.     

Intelligence and the rest of cognition

Cognitive psychologists have become enamored with intelligence. Increasingly, the theories, findings, and methods of what is known as the information processing approach are being used in attempts to explain intelligence related phenomena. This article examines intelligence from a different perspective, which emphasizes domain-specific constraints on knowledge structures. It is argued that conceptions of what intelligence is and how it relates to the rest of cognition can vary considerably when viewed from the vantage points of these two perspectives. The constraints approach views intelligence as being closely related to a special subset of all of our cognitive abilities and as having unique distinguishing properties. It is also argued that the evaluation of any cognitive ability as being intelligent depends crucially on a prior specification of the formal constraints on the domain or domains of knowledge from which that ability originates.     

Interview training with adolescents—A controlled group study incorporating generalization and social validation

Ten school-leavers were allocated either to an interview-training group (E) or a discussion control group (C) for three sessions. For E group a combination of modelling, coaching, roleplay, feedback and discussion was used to train both verbal and non-verbal interview skills. An attempt was made to programme generalization of treatment effect into training and subjective evaluations of interview skill were made by an experienced Personnel Officer to assess the social importance of the skills trained. After C group had completed three sessions to control for the non-specific effects of being in therapy, they received the same training as E group. Subjects were assessed using videotaped roleplayed interviews at the beginning and end of each training phase. After training E group showed significant improvements on both global and specific ratings of interview skill compared to C group; there was evidence of generalization and maintenance of treatment effect and the social importance of the skills trained was substantiated by the subjective evaluation data. C group then went on to replicate the changes in E group.     

Some sources and consequences of career exploration

The present research investigated (a) factors that may influence participation in career exploration, and (b) the role of anxiety in the exploration process. The sample consisted of 161 undergraduate college students. Work-role salience (the importance of work in a person's life) was positively related to participation in self-related and work-related exploration. Self-related exploration was positively related to satisfaction with the occupational decision of low anxiety students and was negatively related to satisfaction among high anxiety students. Furthermore, dissatisfaction with an occupational decision was more likely to stimulate future work-related exploration for low anxiety students than for highly anxious students. The implications of these findings for the career exploration process were discussed.     

Testimony Concerning Possible Jury Bias in a Black Panther Murder Trial1

This paper reports the application of basic social psychological data to the problem of jury selection procedures in a murder trial. Professional testimony in pretrial proceedings was addressed to potential juror bias arising from the fact that the defendant was (a) black, (b) poor, (c) a Black Panther, and (d) on trial for murder. Some observations regarding the impact of the testimony are made and some future research avenues are discussed.     

Binocular summation in the evoked cortical potential

Computer-averaged evoked potentials were recorded from six subjects presented with flashes under conditions of binocular and monocular viewing, with a device fitted over each eye to produce ganzfeld conditions. Tests were run with red light and with blue. Analysis of the evoked potentials indicates a substantially larger amplitude with binocular stimulation.     

Very long-term memory for knowledge acquired at school and university

Recent research into the very long-term retention of knowledge originally acquired during the process of formal education at school and university has demonstrated that such knowledge may be retained at high levels over very long retention intervals. The pattern of retention typically takes the form of a comparatively short period marked by forgetting (lasting between 1 and 6 years) followed by a long period of stable retention (usually longer than 30 years). For courses taken at school the level attained over a series of courses (e.g. in learning a foreign language or studying mathematics) is an important determinant of long-term retention. Students who attain moderate or advanced levels of learning show high levels of retention with very little forgetting, whereas students who attain only lower levels of learning show steady forgetting, and after a period of 6 years retain very little knowledge. Similar patterns of retention are present for university students taking single courses in science and literature subjects, and students with higher grades retain more knowledge although the reliable relationship here, between grade obtained and amount remembered, is weak and accounts for only small portions of the variance in retention. Taken together these findings suggest that the retention of knowledge acquired through formal education persists over longer periods of time than popularly believed. Recent theory proposes that these long-lasting effects of education are partly related to the types of learning schedules followed during acquisition and partly related to the nature of the to-be-acquired knowledge, and to whether or not knowledge can be represented schematically.
