A search for predictive factors in institute supervised cases: a retrospective study of 183 cases from 1959-1966 at the Boston Psychoanalytic Society and Institute.

The purpose of this project was to determine if it is possible to predict from the information contained in the write-ups of the preliminary evaluations of patients accepted for Institute supervised analyses those patients who would successfully complete their analyses and those who would not. Three raters independently studied the write-ups of 183 cases treated at the Boston Institute during the period 1959-1966. Each rater filled out a questionnaire of 105 items which were thought to be of possible predictive value. Outcomes were sought from the analysts who treated the patients. 130 outcomes were obtained and revealed that the patients fell into 4 distinctly different outcome groups: (Group 1) those who completed analysis by mutual agreement between the analyst and patient; (Group 2) those who prematurely terminated their analyses against the advice of their analysts; (Group 3) those whose analyses were prematurely interrupted by their analysts; (Group 4) those whose analyses became interminable. Statistical analyses were done to see which of the 105 predictor items distinguished these four distinct outcome groups. Many of the predictor items were not useful because they either showed no variation among patients, or were too often left blank, or were rated with very low interrater agreement. Of the remaining items, we found ten items which did show a highly significant difference between Group 1 patients and those patients in at least one of the other three outcome groups. We found five other predictor items which showed large, although not quite statistically significant, differences between Group 1 and at least one of the other three groups. Of these 15 items, 7 dealt with family history. The others concerned the patient's past history (2), object relationships (2), patient's sex (1), symptomatic state (1), field of endeavour (1), and history of previous psychotherapy (1). We found it made no difference in terms of these 4 outcome groups what the patient's diagnosis was or whether he was a 1st, 2nd, 3rd or 4th supervised case. Among the other negative findings were patient's age and the ability to experience and tolerate felt anxiety. These did not distinguish any of the outcome groups. These findings show that additional predictively useful information is present in the preliminary evaluations of patients already screened and accepted for Institute analysis by trained evaluators. These results suggest that one particularly important area on which to focus future attention is family history.     

Explicit syllable and phoneme segmentation in the young child

To write a language, one must first abstract the unit to be used from the acoustic stream of speech. Writing systems based on the meaningless units, syllables and phonemes, were late developments in the history of written language. The alphabetic system, which requires abstraction of the phonemic unit of speech, was the last to appear, evolved from a syllabary and, unlike the other systems, was apparently invented only once. It might therefore be supposed that phoneme segmentation is particularly difficult and more difficult, indeed, than syllable segmentation. Speech research suggests reasons why this may be so. The present study provides direct evidence of a similar developmental ordering of syllable and phoneme segmentation abilities in the young child. By means of a task which required preschool, kindergarten, and first-grade children to tap out the number of segments in spoken utterances, it was found that, though ability in both syllable and phoneme segmentation increased with grade level, analysis into phonemes was significantly harder and perfected later than analysis into syllables. The relative difficulties of the different units of segmentation are discussed in relation to reading acquisition.     

NOTE ON SIMULTANEOUS DISCRIMINATION OF VISUAL ATTRIBUTES

van der H eijden A. H. C. Note on simultaneous discrimination of visual attributes. Scand. J. Psychol ., 1972, 13 , 71–72.—A tachistoscopically presented stimulus, provided it is above threshold, results in a visual image with a minimum duration of about 250 msec. In experiments on visual information processing, therefore, the results must be interpreted in terms of 'effective stimulus duration' (exposure time and duration of visual image) rather than exposure time alone.     

Testing some implications of the sensory physiological model of the time sense

Summary In this paper some implications of the pulse generator model of time perception have been tested. In the case of serial (re)production of an interval a lengthening effect occurs. Generally, this phenomenon is explained by assuming that the time-keeper is driven by the state of general physiological activation which decreases in the course of the task. An experiment was carried out in which EEG activity was recorded during the time estimation process. It appeared that a lengthening effect occurred, but there was no correlation between the reproduction times and the means of the EEG spectra, however. In a second experiment two series of time estimations were compared as a function of administering a placebo and methamphetamine. In the latter case the model predicts that no lengthening will occur since arousal (at least for a short period of time) is kept at a high and constant level. In fact, no differences between the regressions of the time estimation curves before and after drug administration have been found, so that the predictions of the model as regards the origin of lengthening could not be supported. It is suggested that the nature of the effect should be studied within the framework of the cognitive theory of time experience which offers various starting points in this respect.     

Earman on the causal theory of time

Conclusion I have so far ignored Earman's Section IV in which spatiotemporal coincidence is discussed. The answer will be clear from the preceding: the exact definitions and principles of the exact theories we have displayed are to be discussed with reference to the special and not the general theory of relativity. But moreover, Earman's transition from (C) to (1) assumes what we do not grant: that events are causally connectible exactly if the points in the mathematical space-time at which they are located are linked by a causal curve.This captures in a nutshell my own conclusions. The first is that the causal theory, after its success vis-à-vis the STR, must now provide a detailed analysis of spatiotemporal concepts in the GTR. The second is that the points raised by Earman do not provide substantive reasons for doubting the adequacy of the causal theory to this task, because Earman insists in his extrapolations on a much closer relation between the empirical structure of events and the mathematical structures that model it than ought to be assumed.I wish to acknowledge gratefully my debt to Dr. A. Grünbaum, University of Pittsburgh, to Dr. C. Glymour, Princeton University, and to the support of the John Simon Guggenheim Memorial Foundation.     

Sequence influence on the organization of meaningless serial stimuli: economy after all

This article provides evidence for an extension of structural information theory, a theory which describes perceptual organization formally, into a more general theory of representation that takes the role of organizations obtained earlier into account. In eight experiments, subjects study series of colored dots. Each series contained 6-8 dots of different colors, and viewing time was between 400 ms and 60 s. In several experimental procedures, subjects recalled the series presented. The experiments systematically varied the economy of the organizations of the series as described by structural information theory as well as a number of aspects of the context in which the series were presented, like order of presentation of a series, order between the series, viewing span, viewing time, and recall procedure. Recall was influenced both by the economy as well as by the context. It is shown how the context influences the relative strength of the most economical organization as compared with rival, local organizations. A structured network model is presented that accounts for the influence of both the economy and the context.     

Agoraphobia and Locus of Control

This study investigated whether external locus of control, as measured with the Rotter Internal-External Locus of Control Scale, is a specific feature of agoraphobia or whether it characterizes neurosis in general. Forty agoraphobic patients, 81 nonagoraphobic neurotic controls, and 49 normal controls completed the Dutch version of the Rotter Internal-External Locus of Control Scale. Agoraphobic patients were found to have a more external orientation as compared to the normal controls, but as a group, they could not be identified as being different from neurotic controls.This study was supported in part by a grant from the Dutch Organization for Fundamental Research (ZWO/Psychon 560-268-001).
