An investigation of planned helping behavior

It is argued that stable, individual differences in helping behavior have not generally been observed in previous research because of the type of helping studied. This paper advocates the study of planned helping behavior as opposed to spontaneous helping behavior. The results of three studies are reported. In Study 1, an instrument designed to measure level of involvement in planned helping activities was developed. Scores on this instrument were found to be stable over a 7-month period. Further analysis revealed two major types of planned helping: (a) formal, organizational helping and (b) informal helping between friends and family. Study 2 examined a variety of intrapsychic and demographic correlates of formal and informal planned helping. Study 3 found support for the hypothesis that people in helping professions have higher levels of involvement in everyday planned helping than do people in nonhelping occupations. It is concluded that the study of planned helping, although posing methodological difficulties, is a necessary adjunct to experimental research.     

The control of social desirability in personality inventories: A study using the principal-factor deletion technique

The present study sought to investigate Paulhus' (1981) principal-factor deletion technique (PFDT), a factor analytic method for controlling for socially desirable responding. Adult subjects (N = 330) responded to both forms of the Eysenck Personality Inventory and a 32-item lie scale. Peer ratings of extraversion and neuroticism served as criterion measures. The factor deleted by PFDT more closely reflected neuroticism than impression management. Factors resulting from PFDT were considerably less valid and less content saturated than those emerging from an ordinary factor solution. The implications of these results are discussed from the perspectives of predictive and construct validity.     

Optic aphasia, optic apraxia, and loss of dreaming

A 47-year-old man with a left temporo-occipital infarct in the area of the posterior cerebral artery is presented. The neuropsychological examination did not reveal aphasia or gross mental deficits. The patient presented with alexia without agraphia, color agnosia, but few visual perceptual deficits. The main impairment was in confrontation naming; he was incapable of naming objects and pictures, not from lack of recognition (excluding visual agnosia) but from lack of access to the appropriate word (optic aphasia). The patient also exhibited a deficit in the evocation of gesture from the visual presentation of an object (optic apraxia) and a difficulty in "conjuring up" visual images of objects (impaired visual imagery) and loss of dreams. The fundamental deficit of this patient is tentatively explained in terms of visuoverbal and visuogestural disconnection and a deficit of mental imagery.     

Sex roles and depression: A preliminary investigation of the direction of causality

The present study examined the direction of the relation between sex role self-concept and depression. A total of 23 males and 32 females were given the Personal Attributes Questionnaire and the Beck Depression Inventory at two times separated by a 3-month interval. Results of a cross-lagged panel correlational analysis found no evidence for sex role orientation as a cause of depression. Instead, the data suggested that emotional well being precedes self-perceived instrumentality, but the influence of third variables could not be overlooked. The implications of these data are discussed with particular reference to the need for more complex theoretical formulations of the relation between self-perceived instrumentality and adjustment.     

Subcortical aphasia with deep dyslexia: A case study of a Japanese patient

The reading performance of a Japanese Broca-type aphasic patient on a single-word reading test was investigated. The result indicated that the subject fits the symptom complex of deep dyslexia in more than one aspect. Unique characteristics of this subject included (1) the isolated subcortical site of the lesion, which apparently produced deep dyslexia, and (2) double dissociations between kanji and kana processing and between oral reading and reading comprehension. The performance of this subject was compared with that of another Japanese deep dyslexic subject in S. Sasanuma (1980, In M. Coltheart, K. Patterson, & J. C. Marshall (Eds.), Deep dyslexia, London: Routledge & Kegan Paul). A theoretical implication was attempted based on a dual coding process scheme by S. Sasanuma and O. Fujimura (1978, Cortex, 7, 1-18).     

The word-superiority effect under conditions that approximate reading

Observers detected a briefly flashed target letter embedded in word, pronounceable nonword, and unpronounceable nonword contexts. The word context facilitated perception under both holistic and analytical processing strategies; the facilitative effect was enhanced when processing was analytical.     

Group differences in intelligence and speed of information-processing

Three samples of different levels of mental ability, but each of average or above- average intelligence, were administered a battery of reaction time test which measure the speed with which persons can execute various elementary cognitive processes. Discriminant analyses revealed significant differences between the groups in reaction times and intraindividual standard deviations, and univariate analyses indicated that higher ability groups tended to obtain significantly faster mean reaction times and to show significantly less intraindividual variability than lower ability groups. Groups which differed the most in mental ability differed to the greatest extent on the more complex reaction time tests but this pattern was reversed for groups which were relatively close in mean IQ. Generally, the results support the hypothesis that speed- of-processing is an important factor unferlying intelligence, but a number of puzzling findings indicate the need for continued research in this area.     

Variable-interval schedules of timeout from avoidance

Rats were trained on concurrent schedules in which pressing one lever postponed shock and pressing the other occasionally produced a 2-min timeout during which the shock-postponement schedule was suspended and its correlated stimuli were removed. Throughout, the shock-postponement schedule maintained proficient levels of avoidance. Nevertheless, in Experiment 1 responding on the timeout lever was established rapidly, was maintained at stable levels on variable-interval schedules, was extinguished by withholding timeout, was reestablished when timeout was reintroduced, and was brought under discriminative control with a multiple variable-interval extinction schedule of timeout. These results are in contrast with Verhave's (1962) conclusion that timeout is an ineffective reinforcer when presented to rats on intermittent schedules. In Experiment 2 the consequence of responding on the timeout lever was altered so that the shock-postponement schedule remained in effect even though the stimulus conditions associated with timeout were produced for 2 min. Responding extinguished, indicating that suspension of the shock-postponement schedule, not stimulus change, was the source of reinforcement. By establishing the reinforcing efficacy of timeout with standard variable-interval schedules, these experiments illustrate a procedure for studying negative reinforcement in the same way as positive reinforcement.
