The effects of head and eye turns on the right ear advantage in dichotic listening

The aim of the present experiment was to investigate the effects of head and eye turns on the ear advantage in dichotic listening (DL) to CV-syllables. Since head and eye turns also mean focusing attention to either the left or right side in space, a second aim was to evaluate recent arguments that ear advantages seen in DL are caused by the perceived position in space of the sound source. Forty right-handed females had 36 trials of CV-syllables under four different instructions. One group (n = 20) was instructed to turn their head (but not their eyes) to the right, the left, or straight ahead during stimulus presentations. The fourth condition was a standard (no instruction) condition. A second group (n = 20) had the same instructions but were told to turn their eyes instead of their heads. Conditions were pseudo-counterbalanced across subjects. Consistent with other studies, results showed a right ear advantage (REA) in both groups during all conditions. However, the REA was largest for the standard condition. Also, more subjects showed a REA during the standard condition, and especially compared to the turn-right condition. It is concluded that dichotic performance is not caused by selective attention to either side in space, and that lateral turns of the head and the eyes contralateral to the left hemisphere have an inhibitory (if anything) effect on the REA.     

Coping with job stress and burnout in the human services

A mail survey of 141 human service workers investigated the effects of coping on psychological strain and "burnout" produced by job stress. The survey assessed job stressors and coping strategies with open-ended questions and measured strain using closed-ended alienation, satisfaction, and symptom scales. Because previous research suggested that individual coping responses do not alleviate strain produced by job stress, the survey elicited information on group coping (social support) and on coping strategies initiated by agencies. Job stress was associated with high levels of strain, and group coping with low levels, but individual responses had little effect. Although workers identified many strategies that agencies could use to reduce stress and strain, actual use of such strategies was slight. Because men and women worked in the same jobs, no sex differences in individual coping were predicted and none were found; women, however, reported more social support than men. There was no evidence for moderating (interaction) effects of stress and coping on strain.     

Results of cerebral computer tomography in the diagnosis of tumors of the sella region

Computer tomography (CT) is an important aid to the diagnosis of sella tumours because it images the tumour directly and delineates it from the healthy tissues. The tumour type can be identified to a certain extent, but angiography is necessary to distinguish tumours from aneurysms. The study is based on 140 surgical and histological examinations, the results of which were compared wit those obtained by CT. Suprasellar inflammations could always be identified by CT. Although intrasellar tumours may be identifiable by CT if full use is made of the potential of the equipment, negative CT results do not necessarily mean that there is no tumour. The diagnostic validity of the method is restricted by the absence of "standards", against which the variable images of intrasellar structures can be judged, and the restricted resolution of CT.     

Prognosis in primarily pure absence epilepsy

17 patients out of a total of 93 treated for primarily pure absence-epilepsy experienced secondary grand mal-seizures and eeg of 8 patients showed a grand mal-disposition (irregular s-w). These 25 patients, compared with the remaining 68 patients, attended more frequently a special school for mentally retarded children, their marks were worse, they left school in a lower form, and their vocational education was less qualified. 8 patients out of 65, who were primarily treated with Suxilep and without additional grand mal-remedy, experienced secondary grand mal-seizures (relative frequency 0.12). The question of the necessity of primary grand mal-prophylaxis is beeing discussed.     

MMPI correlates of extreme field independence and field dependence in a psychiatric population.

34 male and 34 female hospitalized psychiatric patients were divided into field-independent and field-dependent groups on the basis of rod-and-frame test performance and their MMPI scores were compared. A multiple discriminant analysis followed by a series of 2 X 2 factorial analyses of variance was used to assess the results. As in previous studies, more similarities than differences were found between the two cognitive styles. However, field-independent subjects tended to be more unconventional, aggressive, antisocial, and perhaps defensive than field-dependent subjects. Explanations of results were explored in reference to previous findings.     

Color preferences, extraversion, and neuroticism of art students.

Color preferences of 190 art students (G?tz & G?tz, 1974, 1975) were compared with the corresponding scores on extraversion (E) and neuroticism (N). It was found that the preferences of a group of 27 highly gifted young artists were different from preferences of average and less gifted Ss who had little or no artistic practice. In the latter group extraverts and ambiverts mainly preferred primary and secondary colors (light clear and dark clear tones included), while introverts preferred tertiary colors (earth colors) and achromatics. However, in the group of highly gifted Ss no significant differences between positive and negative rankings in both color categories were found. Neuroticism had no effect on color preferences; this holds for introverts and extraverts and for each single color.     

Color preferences of art students: surface colors: II.

In a previous study (G?tz & G?tz, 1974b) the preferences of 14 surface colors were analyzed. While this set contained only one red, one blue, one yellow, etc., the color set of the present investigation was extended, and the preferences of 5 different reds, blues, yellow, etc. were analyzed. Between the five variations of red and yellow, respectively, the greatest affective differences were found, while the opposite was true for the 5 oranges, pinks, and grays. The most preferred colors are 2 reds, 2 blues, and 2 yellows; least preferred are a greenish yellow, a penetrating red-violet, and all 5 pinks. Significant sex differences were found for 8 colors.     

Pathological visual field and brain tumor]

The general relationships between an operatively or autoptically localized tumor and the visual field determined by means of ikineticer perimetry are investigated, the patient stock being a total of 1756 neurosurgical brain-tumor inpatients. Examination of the visual field was possible with four fifths of the brain-tumor patients. Hemianopic, quadrantanopsic, or scotomatous defects of a topically localizable nature could be found in almost one third of the total patient stock available for examination. The clinically particularly interesting criteria of localization of homonymous-hemianopsia defects such as macular sparing and incongruence/congruence of visual field changes should be of no importance to the localization within the visual pathway of brain-tumor patients.     

Relations between pneumoencephalographic and electroencephalographic findings in childhood]

During simultaneous testing of electro-encephalograms and pneumoencephalograms in 200 children of various ages a proven correlation of statistics between both test procedures emerged as a well-defined parameter for evaluation. When making a statement about the correlation in findings between E.E.G. and P.E.G. the age of development in a child must be taken into consideration. Thus it emerged that in infants pronounced enlargement of the ventricular system correlates with active tension E.E.G. at increased inter-cranial pressure, while the coincidence of focal changes in E.E.G. and P.E.G. with advancing years becomes at first more pronounced after the tenth year of life (or puberty) but afterwards lessens.     

Information-theoretical error analysis of a form-comparison test]

An attempt has been made to make an error analysis, by both the conventional and information theoretical mode of evaluation, of the results of a forms comparison test used for diagnosing the sensory and optical capacity of differentiating. A total of 423 test subjects were available for this program. Data for the standardization of this test and for the evaluation of test results was derived from the results of this investigation.
