Economic,life, and disorder changes: Time-series analyses

Implicit in recent social science research and political discussions is a model linking the economy to mental disorder through the intervening constructs of life change and trauma. Using time-series analysis of a 16-month survey in Kansas City, Missouri (n = 1,140), economic and noneconomic life events and the Midtown scale were predicted using a variety of economic measures for the standard metropoliton statistical area. Both life event variables and the symptom measure were related positively to unemployment, and absolute economic change measures lagged 1 and 2 months. However, the life event variables were not strongly associated with the Midtown scale. Most striking of the subgroup findings was that, on the Midtown scale, the low-income group was more responsive than the middle-income group to economic fluctuations.     

Continuity and Discontinuity in Vocational Development Theory

The main purpose of this paper is to point out that theories of vocational development that are derived from research should be based on relatively heterogeneous samples if they are to apply to males in general. The theories should, in addition, use the same pool of constructs in dealing with continuity and discontinuity of vocational development. An outline of such a theory is presented and one aspect of it investigated. The results suggest that such an approach may have validity. It is demonstrated that there is a positive relationship between stability of vocational field preferences and continuity of vocational development Supporting evidence was found for the validity of Roe's classification of vocational fields in a circular array.     

New reasons for realism

Summary Both the psychology of perception and the philosophy of perception seem to show a new face when the process is considered at its own level, distinct from that of sensation. Unfamiliar conceptions in physics, anatomy, physiology, psychology, and phenomenology are required to clarify the separation and make it plausible. But there have been so many dead ends in the effort to solve the theoretical problems of perception that radical proposals may now be acceptable. Scientists are often more conservative than philosophers of science. I end, therefore, as I began, with a plea for help.     

Factoring the circumplex

This paper presents a way of factoring the Guttman circumplex to get factor weights whose pattern is close to that postulated by Guttman for the circumplex. An empirical example, including a crude procedure for diagonal estimation, is shown. Other sources of nonuniqueness are discussed, and the limitation to odd-numbered complexity for the tests is indicated. An orthodox factor analysis is applied to the example, and this provides a basis for comparison of the two opposing models.     

Predictive Indices of the GATB

The study reported here investigated the use of the General Aptitude Test Battery for identification and counseling of students in vocational and academic clases in Ohio secondary schools. Frequency distributions of the GATB aptitude scores were developed for 4,000 ninth- and tenth-grade boys and girls. A multiple regression analysis was performed using the aptitude scores of the GATB as the independent variables, and point hour ratio and single subject grades at the end of one year as the dependent variables. Freshmen and sophomore grade-point average separately and in combination were the criteria used to determine the predictive ability of the aptitudes of the GATB. The GATB was useful in the predictive role for ninth- and tenth-grade achievement in most of the areas studied.     

“Subliminal cues” and the Miiller-type illusion

Using the viewing box from a 2-field tachistoscope, feathers-arrows from 1 field were superimposed upon line-pairs from the other field to construct the Muller-Lyer illusion. 6 Os were tested for the illusory effects under 4 conditions of feather-arrow detectability: (a) d′=O, (no luminance); (b) d′=.42; (c) d′=1.00 and (d) d′=3.7. The length differences of lines of any given pair were a in., 1/64 in., 2/64 in., or 6/64 in. The illusion effect was observed when the feather-arrow d’ equaled 3.7. No significant nor suggestive illusion effects were found for the other feather-arrow detectability conditions.     

A developmental study of visual search behavior

Children in second, fourth and sixth grades and college sophomores were compared on a visual search and scanning task under three experimental condilions. In Condition I, a single target letter was sought in a list of letters of low visual confusability. In Condition II, two target letters were sought but only one appeared in a given list. In Condition III, a single target letter was sought in a list of letters of high confusability. Search time decreased with age in all three tasks. Searching for two targets was no harder than searching for one. A highly confusable visual context increased search time at all age levels.
