Conditional reflexes as related to hypnosis and hypnotic techniques

Hypnosis has never been adequately explained in terms of conceptual framework of most schools of psychotherapy. The psychoanalytic concept that it consists of submission and surrender of important ego functions to the therapist does not explain all observed facts. During my wartime studies and since, I have been impressed by the observation that the patient’s ego is by no means powerless and defenseless, even during a deep state of trance, i.e., in states of trance sufficiently deep to eliminate awareness of painful body injuries (1965). Erickson (1954) has shown on many occasions that in resistant subjects one of the best ways to induce trance is to encourage the patient to resist as much as he can. Haley (1963) has pointed out in detail that at the beginning of any hypnotic relationship there evolves a subtle battle for “one-upmanship.” These observations certainly show that surrender in the psychological sense is by no means an aspect of even the most successfully induced trance states.     

On axiomatization of many-valued logics associated with formalization of plausible reasonings

This paper studies a class of infinite-valued predicate logics. A sufficient condition for axiomatizability of logics from that class is given.To the memory of Jerzy Supecki     

Varieties of size-specific visual selection

Compared time to evaluate stimuli of varying sizes. When Ss expect an upcoming stimulus to be a certain size, response time increases with the disparity between expected and actual size. There are, however, 2 size adjustment processes, and they reflect 2 types of visual selection. In the first, a shape-specific image representation is used to separate a visual object from a superimposed distractor. These representations require the type of slow size scaling demonstrated in imagery experiments. The second size scaling process is faster and not shape-specific. At any given time the visual system is set to process information at a particular scale, and that scale can be adjusted to match an object's size. Because both selection mechanisms depend on size, they probably occur at a relatively low, spatially organized processing level. These findings lead to a new explanation for results that had been taken as evidence for attentional selection at the level of object representations.     

Alcoholism and morphologic findings of the nervous system in autopsy cases

154 autopsy cases of alcoholics (120 men and 34 women) were investigated from a neuropathological viewpoint. In only 19 cases could typical diseases of the nervous system caused by alcoholism be found (Wernicke's encephalopathy, central pontine myelinolysis, Marchiafava-Bignami's disease and disorders of the peripheral nerves and muscles). In comparison liver diseases occurred almost five times more frequently in our own material. Diseases caused by alcoholism of the nervous system, the question of brain shrinkage and its partial reversibility, the up to now not completely known effects on the neurophil and cortical cytoarchitectonic are discussed according to the literature.     

Mood profiles of Masters track and field athletes

In several studies attributing positive health benefits to running, the benefits include reduced depression, fatigue, anger, and increased vigor. Until now, little research has focused on Masters track and field athletes. The present study reports on 587 men and women Masters who participated in a mailed survey measuring mood states using the Profile of Mood States. In comparison to other groups of athletes, these Masters tend to be less depressed, less angry, and less fatigued. Attribution to lifestyle and maturity with their sport is discussed.     

Stressed vowel perception in word recognition

The purpose of this study was to measure subjects' ability to detect deliberate stressed, front-vowel misarticulations embedded in two-syllable words. Reaction times to words with various vowel-height misarticulations were examined for 25 women to assess the effect of a specific vowel height change on listeners' ability to recognize a word. Statistical analysis indicated no significant differences between reaction times to initial, stressed vowel changes along the height dimension, suggesting that subjects responded similarly to all vowel errors on the detection task. This finding provides further evidence that stressed-vowel information may serve as a perceptual anchor in guiding a listener during word recognition.     

Effect of click rate and delay on breakdown of the precedence effect

The precedence effect was tested as a function of echo-click delay and click rate after an abrupt switch in location between leading and lagging clicks. Click trains at three rates, 1/sec, 2/sec, and 4/sec, with delays ranging between 2 and 20 msec, were presented to subjects in an anechoic chamber. Duration of the click train after the switch in location was 12 sec, and echo click perceptibility was assessed throughout this period. The number of echo clicks heard was an increasing monotonic function of delay. The subjects reported a "fade-out" of echo clicks after a set number of clicks at each delay, regardless of rate. This result was interpreted as a buildup in inhibition of echoes produced by the ongoing click train. Suppression of echoes was stronger when the leading click originated from the right side than from the left side.     

Initial experiences with cognitive therapy of schizophrenic patients

Based on earlier experiences of various groups of authors, we developed and modified a programme of cognitive therapy for schizophrenic patients. The aim of the application of the therapeutic programme to subacute patients was to decrease subjectively perceptible basic disorders and to improve the functions of performance. The present results and experiences with 4 groups consisting of a total of 31 patients encourage us to continue applying cognitive procedures of therapy. Problems of the ascertainment of measuring values and fundamental questions of therapeutic efficacy are discussed.     

Effects of preshot routine on free-throw shooting

The effect of prohibiting the use of a preshot routine on free-throw shooting in competitive situations was investigated. 25 male high school basketball players were instructed to attempt 50 free throws alternating in blocks of 10 between the use of their preshot routine and shooting without it. To make the situation competitive, subjects were run in groups of five and their performance was recorded on a large easel placed to the side of the free-throw line. A significantly larger number of baskets were made in the preshot routine condition than without the routine. A competitive situation led to a greater decrement in baskets than had been reported in 1986 by Lobmeyer and Wassermen during noncompetitive free-throw shooting.
