Expectancy Accessibility and the Influence of Outcome Expectancies on Adolescent Smokeless Tobacco Use

This study investigated the moderating influence of expectancy accessibility on the relation between outcome expectancies and drug use intentions. Specifically, it was hypothesized that expectancies made temporarily more accessible would predict smokeless tobacco intentions to a greater degree than would less accessible expectancies. In addition, it was anticipated that expectancies regarding positive outcomes of smokeless tobacco use would be better predictors of intention than would expectancies about negative outcomes. Results partially supported the accessibility hypothesis, but this effect occurred for positive outcome expectancies only. In addition, the anticipated prepotency of positive over negative expectancies in predicting drug use intentions was strongly supported. These findings are consistent with theories of problem behavior which differentiate between positive and negative outcome expectancies and which postulate that accessibility of expectancies plays an important role in expectancy-behavior relations.     

Holism: Revolution or reminder?

Conclusion Among the four propositions considered in this paper, we have found two which can contribute to a holistic environmental ethic: individuals acquire some of their value through participating in communities, including biotic communities, and wholes, including biotic communities, can have values which are not the sum of the values of the individuals composing them. However, accepting these propositions does not represent a revolutionary break distinguishing holism from traditional value theories or ethics. On the other hand, the holistic propositions we considered which would clearly differentiate holism from (at least some) traditional value theories and ethics are unacceptable. Consequently, if the propositions we have discussed fairly represent what goes under the name of holism, then rather than being a new kind of ethic, a viable ethical holism will make its contribution by emphasizing the communal elements of traditional ethics which have sometimes been neglected in glorifications of the individual. This would not be an inconsiderable contribution, philosophically, socially, or environmentally.     

Are rules and modules really necessary for explaining language?

Over the past few years Steven Pinker has argued that although some aspects of language may be more associational, and therefore properly modeled in connectionist networks, for the most part human language is still best characterized as a modularized set of rulesymbol systems. In support of his claim, Pinker garners a broad array of clinical, experimental, and observational data from neurology, psychology, and linguistics. Those data, unfortunately, are not compelling because they do not support his position uniquely. In this paper, I show how each of his arguments is compatible with alternative interpretations. I argue, moreover, that in focusing on certain details of connectionist models Pinker and his colleagues actually overlooked both the most serious deficiencies of the connectionist approach and its most significant theoretical contribution. I conclude by sketching briefly some emerging alternatives to connectionism which avoid those deficiencies while retaining its strengths over the rule-symbol systems of linguistic theory.This research was funded in part by University of Idaho Seed Grant 681-Y304.     

Recent Suicidal Ideation Among Patients in an Inner City Emergency Department

The rates and associated features of suicidal ideation among 5,641 patients seeking routine, nonsuicide related care in an inner‐city emergency department were examined. Approximately 8% of patients seeking routine care in the emergency department reported some form of suicidal ideation within the past 2 weeks. Suicidal ideation was common in individuals who were single with poorer mental health, had higher depression, and had received some drug or alcohol treatment in the past 3 months or had used cocaine or marijuana in the past 30 days. Improved screening procedures could help to identify routine care patients who are at risk for suicide.     

The Fundamental Attribution Error and Harman's Case against Character Traits

Abstract

Gilbert Harman argues that the warrant for the lay attribution of character traits is completely undermined by the “fundamental attribution error” (FAE). He takes it to have been established by social psychologists, that the FAE pervades ordinary instances of lay person perception. However, examination of recent work in psychology reveals that there are good reasons to doubt that the effects observed in experimental settings, which ground the case for the FAE, pervade ordinary instances of person perception. Furthermore, it is possible to make sense of these experimental results without invoking the FAE. Harman's argument against lay character trait attribution is unsubstantiated.
