A reflection: Howard Scott Liddell, 1895-1962

Howard S. Liddell, Professor of Psychobiology in the Department of Psychology at Cornell University, was one of the earliest American students and developers of I.P. Pavlov's theory of the conditioned reflex and an early researcher on stress. The significance of Liddell's work on stress was fully recognized when he was sent, as a member of a commission, to the battlefront at the height of the Korean War to study stress and self-control in the soldiers. This profound experience convinced Liddell that behavioral research must ultimately be made relevant to the understanding and elevation of human behavior. He spent the remaining ten years of his life in efforts to implement this conviction through research, writing, and lectures before scientific and lay groups.     

Impulsivity and perception: individual differences in the processing of the local and global dimensions of stimuli

There appears to be an association between a "global" mode of perceptual processing and a cluster of personality traits, one of which is impulsivity. The goal of the present study was to clarify this relationship. Subjects differing in impulsivity (as measured by a self-report inventory) performed speeded cardsorting tasks. They sorted stimuli consisting of large letters made up of smaller letters. Highly impulsive subjects had no more difficulty than other subjects in ignoring the large, "global," letters when they tried to attend to the smaller, "local," letters of which they were composed, nor were they more vulnerable than other subjects to Stroop-like response interference produced by the global letters. High impulsives did have particular difficulty when the task required that they integrate the information provided by the local and global letters. This finding can be explained in terms of individual differences in the value placed on speed relative to accuracy in information processing.     

Induction of depressive affect after prolonged exposure to a mildly depressed individual

Scores on the Beck Depression Inventory (BDI) were periodically obtained from the roommates of college students who exhibited a persistent mild depression over a 3-month period. For comparative purposes, BDI scores were also obtained from roommates of individuals who were transiently depressed and from subjects with nondepressed roommates. In comparison with control subjects, the roommates of persistently depressed persons displayed a progressive increase in BDI score over the course of the study.     

A survey os school psychologists'' use of behavior modification procedures

A national survey of behavior modification procedures used by school psychologists is reported. Usable questionnaires were received from 148 (49%) of 300 randomly selected members of the 1982 National Association of School Psychologists directory. Each respondent was asked to indicate the type of exposure, use, and inclusion of data collection procedures for each of 18 commonly used behavioral techniques. Conditional probabilities between type of exposure and use found strong relationships between supervision and subsequent use. The implications for the field of school psychology and future directions for training programs are discussed.     

Biomagnetism from the neuropsychiatric viewpoint--principles of recent developments in diagnostic procedure

The following survey is intended to demonstrate and discuss some principle problems of biomagnetism and the application in clinical fields. The development of special technical parameters especially by the SQUID method is initiating new possibilities of research and completing the neurobiologically determinated basis and conditions of neuropsychiatric disorders. The Magnetoencephalography (MEG) will be represent an important role of a new functional diagnostic method.     

"Your feet's too big": an inquiry into psychological and symbolic meanings of the foot

The foot is a highly cathected appendage that is commonly singled out as the brunt of humorous or derisive remarks, as if it embodies repugnance and disgust. Attitudes toward the foot are overdetermined, bearing the imprint of man's early linguistic patterns and individual dynamics. This article suggests that feet are symbolic because they bear the feelings derived from earlier separations, good and bad object representations, collective memories, and genital representations. The foot's role as symbol of both the male and female genitals, repository of badness, symbol of passivity, initiator of movement, and site of self-mutilation have been briefly reviewed. As Fats Waller rhapsodizes that the "feet's too big," he finds a convenient way to displace his symbiotic and erotic anxieties vis-à-vis women. Similarly, patients who come for psychiatric treatment and psychotherapy frequently make references to their feet or use them in specific ways. An understanding of this type of communication can often provide insight into individual dynamics and enhance treatment. The weight placed on these communications depends, of course, on the vicissitudes of the previous therapeutic work as well as on the particular problems of the patient.
