Hierarchically distributed processing for psychology

The advantages of loosely coupled hierarchical computer networks for psychological research are discussed. Hardware methods for interconnecting computers are considered, and software communication protocols are detailed. A hierarchy of interconnected computers is formed: (1) large campus computer for statistical analyses, (2) medium scale computer for data concentration and program development, and (3) laboratory computers for data collection. This hierarchy provides efficient computing at all levels and insures maximum computing power at minimum cost.     

ENTRY LEVEL HIRING STANDARDS IN RURAL CENTRAL MINNESOTA

In order to determine the hiring standards for entry level jobs used by employers in rural central Minnesota, a rating scale was developed. On the rating scale, 15 characteristics that seemed important for hiring purposes were included. The rating scale was mailed to 20 employers hiring over 30 employees. All 20 employers returned the rating scales. The results indicate that 100 percent of the employers consider attitude as very important or most important for hiring purposes. Ability (aptitude) was considered very important by 90 percent of the employers. Interests, appearance, and references were considered to be of average or more importance by 90 percent of the employers for hiring purposes. The results should assist entry level job seekers in making more effective applications for work.     

Construct validity of four basic Vocational Interest factors

To find evidence of the generalizability of four interest factors established for tests within the Roe-Holland framework, factor scores derived from a Vocational Interest Inventory grounded in Roe's system were correlated with the empirically based Strong-Campbell Occupational scale scores. For this sample of 300 counseling clients, a majority of the hypothesized relations were found, and arranging the occupations along these bipolar dimensions both sharpened the definitions of the factors and provided an additional interpretive aid for counseling.     

A nomograph for rapid determination of medians

Directions are given for constructing a very simple nomograph for computing medians, which is entered with information from the cumulative frequency distribution. It gives a linear interpolation within the class interval containing the median.     

Effect of client-centred therapy on the coping strategies of sexually harassed students in tertiary institutions in Taraba State,Nigeria

This study examined the effects of client-centred therapy (CCT) on the coping strategies of sexually harassed students in tertiary institutions in Taraba State, Nigeria. It also looked for any gender differences in the effect of CCT on the coping strategies of sexually harassed students. We employed a quasi-experimental and pretest–post-test design with control group. The statistical population comprised 250 students who had experienced sexual harassment in tertiary institutions, of which 20 students were selected using convenience sampling. The students who had been sexually harassed were then randomly assigned to the experimental and control groups. The experimental group subsequently underwent six 60-min sessions of CCT, while the control group received placebo treatment on drug abuse. The research tools included a sexual harassment battery (SHB). Inferential statistics of analysis of covariance (ANCOVA) was used to analyse the data. Cronbach's alpha produced a reliability coefficient of 0.79 for the SHB. The following findings were recorded: (i) client-centred therapy effectively increased the coping strategies of students and (ii) there was no significant mean difference between male and female students in the effectiveness of CCT on coping strategies.     

Developing prediction weights by matching battery factorings

Between-sample shrinkage of validity from sample errors is compounded when usual multiple regression techniques are employed to estimate weights for new battery components. A rationale is described for increasing prediction weight validity through a combination of a reduced-rank regression technique and a method for determining maximal factored congruence between two sets of measures. A numerical illustration is based on data drawn from a problem in academic prediction.Version of paper presented at symposium, Large Scale Academic Prediction Systems, American Psychological Association, New York, September 1966.
