A factor analytic validation of Holland's Vocational Preference Inventory

A principal components analysis was applied to a 135-item pool of the Holland Vocational Preference Inventory, Sixth Revision. The sample consisted of a cross section of 100 men and 200 women college students under the age of 25 yr. An eight-factor structure was defined for each of the sexes which is discussed in relation to Holland's clinically based scales, sex differences and criterion groups as defined by choice of major subject. The a priori clinical scales were partially upheld with differences attributed to the characteristics of the sample and sociopolitical time context during which the test was administered. A new scale emerged relating to an interest in professions involving law and politics.     

Some analyses of the verbal encoding deficit of alcoholic Korsakoff patients

Two experiments were designed to assess Korsakoff patients' ability to encode verbal information on the basis of its physical, nominal and semantic properties. The first investigation employed Wickens' release from proactive interference (PI) technique; a procedure that allows an assessment of a subject's ability to encode verbal information on the basis of its semantic properties. It was discovered that on tasks involving only a rudimentary verbal analysis, such as the ability to discriminate letters from numbers, the Korsakoff patients demonstrated a normal release from PI. However, on tasks that required a more sophisticated level of semantic encoding, such as those based on taxonomic class inclusion, the patients failed to show release from PI. The second investigation employed Posner's reaction time technique which assesses a subject's ability to encode the physical and nominal properties of simple verbal materials (letters). The results of this study showed that Korsakoff patients are impaired on even these rudimentary encoding tasks, which led to the proposal that Korsakoff patients' semantic encoding deficit might stem from an initial impairment in the speed at which physical and nominal properties of verbal information are analyzed.     

UCS duration and conditioned suppression: Acquisition and extinction between-groups and terminal performance within-subjects

Two experiments demonstrated a positive monotonic relation between UCS duration and conditioned suppression ranging from no suppression at 0.05 sec to nearly complete suppression at 3.0 sec. In Exp 1, 5 acquisition groups were run at 0.5 mA. No suppression occurred at the shortest duration, approximately 50% suppression by Session 3 in two intermediate groups (0.2 and 0.5 sec) and nearly complete suppression by Session 3 at the two longest durations (1.0 and 3.0 sec). The relation between UCS duration and recovery of responding during extinction followed a parallel pattern. In Exp 2, terminal performance was studied within-subjects and the same relation was replicated.     

An evaluation of the effects of supplemental “fluency” training during maintenance

The voice onset time (VOT) of two groups of treated stutterers and a normal-speaking group was assessed by spectrographic analysis. Both groups of stutterers had significantly slower VOT than the normal speakers. The experimental group of stutterers was given 8 wk of “fluency” training designed to remediate characteristics of speech identified as related to “tenuous” fluency. The control group of stutterers received ongoing maintenance therapy. Posttreatment VOT was assessed. The experimental stuttering group had significantly decreased their VOT in the direction of the normal-speaking group, whereas the control group of stutterers had a greater VOT between pre- and posttreatment. The implication of these results for the maintenance of fluency are discussed.     

Age and type of crossed aphasia in dextrals due to stroke

Thirty-nine cases (37 from the literature and 2 personal) of crossed aphasia in dextrals due to stroke were reviewed concerning age, sex, and type of aphasia. Results showed that Broca's aphasics are younger than the remaining group, males predominate, and several types of aphasia have been described similarly to the aphasias due to left-hemisphere lesions in dextrals.     

Incomplete Kluver-Bucy syndrome and fluent aphasia

A case of probable herpetic viral encephalitis is presented. The clinical picture following the acute phase of disease was dominated by severe fluent aphasia, prominent oral tendencies, visual agnosia, and a decrease in fear reactions. Most of these symptoms, with the obvious exception of aphasia, are similar to those observed by Kluver and Bucy in rhesus monkeys that underwent bitemporal lobectomy. These manifestations may be explained by the tendency of the herpes simplex virus to invade the temporal lobes. "Agnosia" in the auditory field and changes in vocal behavior were observed by H. Kluver and P. C. Bucy (1939, Archives of Neurology and Psychiatry, 42, 949-1000) in some of their bitemporal monkeys. The association of sensory aphasia, as observed in this case, with the auditory "agnosia" observed in some bitemporal monkeys, is discussed.     

Blood pressure and personality

Three groups of 18-yr-old male Ss were selected from a representative Swedish population according to strict blood-pressure criteria: hypertensives (systotic blood pressure above 146 and diastolic above 90), on two occasions, normotensives (systolic blood pressure between 124 and 131, population mean = 128) and hypotensives (systolic blood pressure between 100 and 106). As a part of a broad multidisciplinary study, personality inventory scales and unpleasantness ratings for various types of situations were administered. The findings for the hypertensives indicated lower assertiveness and higher anxiety-proneness, whereas the hypotensives, compared to normotensives, showed a more impulsive, acting-out personality pattern. The hypertensive group was subdivided according to digital vasoconstriction criteria. The non-vasoconstricted subgroup showed a more impulsive and ‘anger-out’ personality pattern, whereas the pattern obtained in the vasoconstricted subgroup was more similar to the classical hypertensive personality, characterized by anxiety and unexpressed anger.
