Psychological Type: A 32-Year Follow-Up

This study is a follow-up to three previous studies of psychological type published in this Journal in 1964, 1976 and 1978 by Bradway, Bradway and Detloff, and Bradway and Joseph Wheelwright. Participants in all of our studies were limited to Jungian analysts and candidates. Participants of the first two studies and of the current study were from California; participants of the 1978 study included the participants from the previous study plus persons attending the 1974 International Congress in London. In 1993 we sent letters to the 232 current analysts and candidates in the San Francisco and Los Angeles C.G. Jung Institutes, as well as to the nine participants in our 1974 study who were no longer members of the Institutes but could be located, asking them to fill out a questionnaire that included self-typing, and to self-administer the Gray-Wheelwrights Jungian Type Survey (GW). The response rate was high: 196 or 81% of the 241 persons to whom we sent letters returned filled-in questionnaires and GWs; all 67 or 100% of the participants in the 1974 study who could be located returned the filled-in material. Eight of those 67 had also been in the 1961 study. The current study provides data on the changes in psychological type over time, in some instances over a period of 32 years. It added for the first time a consideration of analysts' rating of themselves as primarily clinically or symbolically orientated, and a survey of analyst opinions as to the determinants of psychological type. Summarizing the results: A smaller percentage of analysts typed themselves as intuitive thinking than in 1961; the percentages of congruence between self-typing and the Gray-Wheelwrights scores in the three dimensions (introvert/extravert, sensation/intuition, and thinking/feeling) in 1961, 1974 and 1993 are between 76% and 96%; changes in typology from 1961 to 1993 occur more frequently in the younger age group than in the older age group; 65% of the participants considered the distinction between clinical and symbolic important, but only 41% rated themselves as either primarily clinically oriented or symbolically oriented with essentially no relationship between that orientation and typology; a sub-study of typology of partners within this study does not support the concept that opposites marry; according to the opinion of this group of analysts and candidates as to the determinants of adult typology, genetics (chromosomes) is distinctly the strongest contributor with family dynamics a not-very-close next contributor.     

Logic and the consistency of the world

The claim that nature is self-consistent has recently been contested by a number of paraconsistent logicians. In this paper I will survey the arguments which paraconsistent logicians have presented for the thesis that nature is actually inconsistent. My conclusion is that these arguments all fail.The paraconsistency programme has to date been concerned primarily with outlining the philosophical inadequacy of classical logic, and detailed discussions of issues bearing upon the philosophical adequacy of the paraconsistency position itself are not to be found as yet in the literature. This inadequacy will be illustrated here with respect to the question of the self-consistency of nature.     

Human Freedom and The Counselor

The nature and the source of human freedom have prompted considerable discourse and controversy among behavioral scientists and practitioners. Some believe that man's behavior results from a series of free choices while others contend that all behavior is determined and is therefore not free. This apparent dilemma often leads to the erroneous conclusion that we must either see man as determined and treat personal experiences of freedom as illusory, or preserve the existential experience of being free by denying prior causes for behavior. But there is no essential inconsistency in viewing all behavior as caused while also accepting and valuing the existential experience of being free. Counselors who acknowledge the causes of free experiences are in a position to establish the conditions necessary for such experiences for their clients.     

Detection theory,micromatching, and the constant-ratio rule

The conformance of detection theory and micromatching with the constant-ratio rule (CRR) was determined by calculations for sets of three stimuli and subsets of two stimuli. For an arbitrary selection of sets, the CRR would be expected to hold quite well if either detection theory or micromatching lay behind the responses. For specific stimulus configurations, however, detection theory and micromatching differ considerably from one another and from the CRR. These configurations are found particularly for the univariate distributions, and this corresponds to empirical findings that the CRR holds better for multidimensional than for unidimensional stimuli. It is shown how the differences between the three theories in the implied constancies of ratios can be used in diagnosis of the basis ofempirical confusion matrices.     

Single-trace fragility theory of memory dynamics

In single-trace fragility theory, forgetting is produced by two factors, time and interference. Memory traces are assumed to have two partially coupled dynamic properties, strength and fragility. Strength determines the probability of correct recall and recognition, while fragility determines the susceptibility of the trace to the time-decay process but not to the interference process. Consolidation is assumed to be a continual reduction in the fragility of the memory trace rather than any change in strength or availability. Decreasing fragility accounts for the continually decreasing forgetting rate, the temporal character of retrograde amnesia and recovery therefrom, and the type of internal clock necessary for nonassociative recency judgments. Data are presented to indicate that interference is independent of the interval between original and interpolated learning, that nonassociative recency discriminability approaches a limit at about 30 min, and that the decay rate of long-term retention in amnesic patients is the same as in normal Ss.     

The roles of practice and correction in the categorization of sour and bitter taste qualities

Ten Ss were selected from a group of 40 screened to determine misnaming of stimuli usually called sour (hydrochloric and citric acid) and bitter (quinine sulfate). The 10 Ss were then given 16 trials in which they were asked to match the stimuli to standards, with or without verbal feedback for each stimulus. This was followed by 16 trials without feedback for all Ss and, several days later, by a 16-trial posttest. Final improved performance of the Ss was not affected by having received the feedback. It was concluded that experience with the stimuli leads to a reduction in the degree of misnaming, implying a nonphysiological basis for sour-bitter confusions.     

Factor analysis of the army air forces sheppard field battery of experimental aptitude tests

A factor analysis was made of 39 experimental printed aptitude tests and seven reference tests selected from the Army Air Forces Aircrew Classification Battery. Thirteen factors were extracted and two independent orthogonal rotational solutions were completed. Twelve factors were interpreted. Of these, seven were clearly identifiable with previously known factors: numerical, perceptual-speed, spatial-relations, visualization, visual-memory, paired-associates-memory, and length-estimation factors. A planning factor was not as clearly identifiable. A reasoning factor was probably a composite of two or more factors that failed to separate. A new factor possibly has to do with orientation with respect to the points of the compass. Two factors were doublets, each apparently specific to one kind of test. Better conceptions were gained of the spatial-relations and visualization factors and of the kinds of tests that measure them best. Efforts to improve measures of unique factors were not uniformly successful. The attempt to duplicate a psychomotor test rather directly by analogy in printed form failed almost completely.For support of a large part of the investigation the senior author is indebted to the Social Sciences Research Council for a grant-in-aid. Dr. Fruchter supervised the computational work in the extraction of factors and in one of the rotational solutions. Much of the work was done while he was employed by the Air Training Command Human Resources Research Center. While the opinions and conclusions are those of the authors, they wish to express their appreciation to that organization and especially to Dr. John T. Dailey for making the facilities possible and to Mr. William B. Lecznar for technical and computational assistance.     

A simple graphical method for orthogonal rotation of axes

A simple method of making orthogonal rotations by projecting coordinates from one plot to another is presented. An easily constructed apparatus for rapid and accurate work is described in detail. By the technique proposed 12 to 15 rotations of pairs of axes involving 20 test variables can be completed per hour by a practiced technician.
