Eliminating nail-biting by the habit reversal procedure

Fingernail-biting is prevalent among children and adults alike. About 43% of children bite their nails during the puberty ages (Wechsler, 1931); 25% of college students are nail-biters (Coleman and McCalley, 1948), and 10% of adults bite their nails (Pennington, 1945).A variety of treatments including negative practice, operant procedures and psychotherapy have been used in treating nail-biting but no single treatment has been generally effective in eliminating nail-biting. Smith (1957) using negative practice reported that 21 of 57 (39%) of his nail-biting clients were cured. 9 improved and 27 (47%) were unimproved. Bucher (1968) reported that 13 of 20 (65%) college students stopped nail-biting by using a self-administered operant shock procedure. However, he reported many relapses after the withdrawal of shock for nail-biting. No evaluation of psychoanalytic treatment for nail-biting appears to have been made.     

Age,sex, training,and the measurement of field dependence

This study was designed to: (a) examine the effects of age and sex on a person's susceptibility to field dependence training; (b) determine whether the field dependence phenomenon is a function of “cognitive style” or of a person's general inability to make correct judgments in the face of too much confusing and inaccurate information. Traditional Rod and Frame scoring is based on the latter assumption. Interpretation of results, however, has traditionally been based on the “cognitive style” assumption. Results indicate that Rod and Frame results are not a function of cognitive style. This seems particularly true of two aspects of the field dependence phenomenon: (a) the sex difference effect and (b) the correlation between Rod and Frame and Embedded Figures results. Age, more than sex, may be a function of both cognitive style and general ability to perceive the upright. A training effect was not demonstrated. Hypotheses were put forward to explain the nature of field dependence, the magnitude of field dependence errors, and the lack of a training effect.     

An application of Strong's validity criteria to basic interest scales

E. K. Strong, Jr.'s (Vocational interests of men and women, Stanford, Calif.: Stanford Univ. Press, 1943) four propositions for interest-inventory validity andJ. L. Holland's (Making vocational choices: A theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) hexagonal classification system were synthesized in order to adapt a traditional procedure for determining the construct validity of occupational interest scales to the validation of basic interest scales. The procedure was tested using a sample of 4035 males and 3671 females whose interest inventory results as high school students and whose majors as college seniors could be assigned Holland codes. Results of the study indicate that this procedure can be used to assess the construct validity of inventories using basic interest scales.     

Second-order dimensions of the Work Values Inventory (WVI)

An item factor analysis of the 45 items of the Work Values Inventory (WVI) for 445 physically disabled clients produced six second-order dimensions: Stimulating Work, Interpersonal Satisfaction, Economic Security, Responsible Autonomy, Comfortable Existence, and Esthetic Concerns. These second-order factors provide a summary of clients' work motivation at a higher level of generality that is consistent with the WVI primary structure. The six factors are virtually independent of age, education, and intelligence and can be hand-scored by a simple procedure.     

Dichotic listening in the recovery of aphasia after stroke

Three different dichotic listening tests were given to a group of aphasic patients at various stages of the recovery process. Results were different for each test and in the course of time fluent aphasics demonstrated a tendency to increase right ear preference while nonfluent aphasics showed an increase of left ear preference in the test of dichotic words. The importance of these findings to the understanding of recovery of function is discussed in terms of the role played by the right hemisphere.     

Temporal ordering deficits following anterior temporal lobectomy

Subjects were required to report the pitch sequence of two 10-msec tones of different frequency presented monaurally while the stimulus onset asynchrony (SOA) between the two tones was varied. The value of the SOA at which the subjects achieved an 80% correct sequence report was determined by an adaptive procedure without feedback. This measure was compared in the right and left ears, on subjects with a right or left anterior temporal lobectomy and on a normal control group. The results reveal an elevated threshold for performing temporal order judgments in the ear contralateral to the surgical lesion.
