Asymmetrical effects of Pavlovian excitatory and inhibitory aversive transfer on Pavlovian appetitive responding and acquisition

Predictions of a theory of Pavlovian motivational transfer, which incorporates principles of both the theory of reciprocal inhibition and the Rescorla-Wagner model, were tested in several Pavlovian aversive to Pavlovian appetitive transfer tasks. As predicted, the presence of a signal for an aversive event, conditioned stimulus (AV CS+), reliably suppressed performance of appetitive conditioned responses (CRs) whether imposed during acquisition or on independently established responding. Acquisition of appetitive responding to a novel CS reinforced in compound with an AV CS+, however, was enhanced (“superconditioning”). This observation suggests that the effects of a discrepancy between expectation and actual outcome on a conditioning trial are influenced by the affective value of both the expectation and the reinforcer. These transfer effects were not symmetrical for an inhibitory aversive stimulus (AV CS?). An AV CS? did not enhance appetitive responding compared to a random control condition, nor did the AV CS? reduce (i.e., block) appetitive conditioning to a novel CS when appetitive reinforcement occurred in the presence of the AV CS?. Comparison of the two shock-exposed conditions with a naive control condition suggests that previous results that were apparently consistent with inhibitory aversive enhancement and blocking of appetitive conditioning may have been due to aversive context conditioning.     

Remarks in praise of guilt

This article is an elaboration and extension of an earlier article concerned with guilt and morality in the modern age. The focus is on two general issues arising from what was presented there. First, there is an attempt to explicate the conception of human agency underlying the emphasis on individual responsibility in the original essay. Second, there is a critical examination of the moral relativism position so common in the contemporary world. Both the shrinking conception of human agency and responsibility and the growing acceptance of moral relativism are strongly criticized, and it is concluded that a rationally-based morality must be defended against those many persons today for whom ‘anything goes’ in the realm of human behavior.     

Sex-role stereotypes and clinical judgments of mental health: The Brovermans' findings reexamined

This study attempted to evaluate the progress of mental health professionals regarding sex-role stereotyping in clinical functioning, identified as a problem over 10 years ago by Broverman et al. (Journal of Consulting and Clinical Psychology, 1970, 34, 1–7). A comparable format and questionnaire were used in order to replicate faithfully the earlier study and facilitate past-present comparisons. One hundred four psychiatrists, psychologists, and social workers were randomly assigned to three instruction-set conditions in completing the Stereotype Questionnaire: sexunspecified adult instruction set, female instruction set, and male instruction set. No significant differences were found related to sex of clinician. A significant effect (p<.001) was found for social desirability and what was judged as healthy for sex-unspecified adults. No significant relationship was found, however, for social desirability of traits and conventional sex-role stereotypes. Based on the results of this study it is possible to speculate either that the Boverman results were primarily an artifact of their forced-choice methodology or that progress has been made in a more nonsexist direction among mental health professionals. Limitations of this research are presented and considered relative to the Brovermans' study. The basically attitudinal nature of this work is noted and the question is raised as to whether nonsexist attitudes are translated into nonsexist clinical functioning.     

Worksite stress management interventions

Despite the general agreement that stress plays a role in everyday life, there continues to be substantial controversy about how stress can be managed at the worksite. During the last decade, our knowledge of stress management interventions has increased substantially. Despite this improvement, deficiencies in the literature exist. In this article, we offer a framework that may be used for viewing organizational stress interventions, briefly review some of the stress management intervention literature in the context of this framework, and identify future needs that may be particularly appropriate for organizational psychologists to address.     

The effects of processing requirements on neurophysiological responses to spoken sentences

Ten English speaking subjects listened to sentences that varied in sentential constraint (i.e., the degree to which the context of a sentence predicts the final word of that sentence) and event-related potentials (ERPs) were recorded during the presentation of the final word of each sentence. In the Control condition subjects merely listened to the sentences. In the Orthographic processing condition subjects merely listened to the sentences. In the Orthographic processing condition subjects decided, following each sentence, whether a given letter had been present in the final word of the preceding sentence. In the Phonological processing condition the subjects judged whether a given speech sound was contained in the terminal word. In the Semantic processing condition subjects determined whether the final word was a member of a given semantic category. A previous finding in the visual modality that the N400 component was larger in amplitude for low constraint sentence terminations than for high was extended to the auditory modality. It was also found that the amplitude of a N200-like response was similarly responsive to contextual constraint. The hypothesis that N400 amplitude would vary significantly with the depth of processing of the terminal word was not supported by the data. The "N200" recorded in this language processing context showed the classic frontocentral distribution of the N200. The N400 to spoken sentences had a central/centroparietal distribution similar to the N400 in visual modality experiments. It is suggested that the N400 obtained in these sentence contexts reflects an automatic semantic processing of words that occurs even when semantic analysis is not required to complete a given task. The cooccurrence and topographical dissimilarity of the "N200" and N400 suggest that the N400 may not be a delayed or a generic N200.     

Young patients detained under the Lieutenant Governor Warrant in Ontario

Few studies have focused on mentally ill juvenile offenders who end up on warrants of the lieutenant governor (LGW). The present study arose out of a larger study (1982) of all patients (N = 332) being held on lieutenant governor warrants in Ontario, Canada. Of this group, 24 were placed on warrants as juveniles (18 years and younger). The characteristics of this group, who are predominantly males with histories of psychiatric illnesses, diagnosed mainly as antisocial personality, and who have been found not guilty by reason of insanity on charges primarily of murder, or attempted murder, are described. In light of the proposed Young Offenders Act, a further study of all juveniles held on warrants of the lieutenant governor in Canada is proposed.     

A drop in suicides around major national holidays

To study the fluctuation of suicides around the holidays, we examined 188,047 U.S. suicides from 1973 to 1979. Correcting for the effects of extraneous variables, such as seasons and days of the week, we found that suicides dropped by an annual average of -102.5 in the period surrounding the holidays. One set of holidays (Memorial Day, Thanksgiving, and Christmas) was associated with an unusually low risk of suicide before, during, and after the holiday. Another set of holidays (New Year's Day, July 4th, and Labor Day) was associated with a low risk of suicide before the holiday and a high risk just afterwards. Almost all demographic groups experienced a low risk of suicide around the holidays: whites, blacks, males, females, retired persons, and persons of working age. Only white teenagers deviated from this pattern. Thus, the evidence does not support the widespread popular assumption that holidays are a risk factor in suicide.     

WIEMAN'S MISUNDERSTANDING OF DEWEY: THE CHRISTIAN CENTURY DISCUSSION

Abstract. An important issue in the development of the American school of philosophy known as critical naturalism was whether the naturalistic vision implied a humanistic or a theistic interpretation of religion. Is the divine a creativity within nature but more than human effort, or is it the human vision of ideal possibilities and the effort to realize them? This issue is clarified through a study of the concept of the divine developed by the leading naturalist John Dewey in A Common Faith, the misunderstanding of this book by Henry Nelson Wieman, and the discussion of this misunderstanding in the pages of Christian Century. The essay concludes that Wieman's misunderstanding of Dewey is instructive in that it reveals unintended possibilities in Dewey's thought.
