God and perceptual evidence

I presented a substantially different version of this paper at the 1991 American Philosophical Association Central Division Meeting. William L. Rowe commented. The paper in its present form has profited considerably from Rowe's comments.     

The Effect of Contextual Factors on Individuals' Job Performance

The intent of this study is to apply a cross-level design to examine the influence of contextual factors upon individuals' performance. The results support the hypothesis that peer group characteristics predict individual performance beyond individual characteristics. The implications for using a cross-level approach to study the effects of contextual variables on individual-level phenomena are discussed.     

Noncompliance with Persuasive Appeals for a Prosocial,Altruistic Act: Blood Donating1

Effects of persuasive messages, responsibility denial (RD), and attitude-accessing on blood-giving attitudes, intentions, moral obligations, and behavior were examined. In Study 1, participants (n= 84) who heard a message emphasizing moral reasons for donating indicated a more favorable postmessage attitude and stronger moral obligation to donate than participants exposed to a message aimed at reducing fear, a combined moral and fear- reduction message, or no message. Combined message participants showed greatest intent to donate, yet only 14% of all participants attended a campus drive. In Study 2, low (n= 52) and high (n= 60) RD individuals heard the message arguments and were asked to access their attitudes. Low compared to high RD individuals stated a stronger sense of moral obligation, particularly when they accessed their thoughts relevant to blood donating, and behavioral intention, especially in the combined message condition. Few participants attended a blood drive (12.5%), yet most were low RD individuals from the nonaccessed attitude condition (83%). Results suggest that few individuals will engage in the altruistic act of blood donating, despite the experimental use of persuasive messages and accessing issue-relevant attitudes.     

Factors and Taxa, Traits and Types, Differences of Degree and Differences in Kind

ABSTRACT A taxon is a nonarbitrary class whose existence is conjectured as an empirical question, not a mere semantic convenience. Numerous taxa are known to exist in nature and society (chemical elements, biological species, organic diseases, geological strata, kinds of stars, elementary particles, races, cultures, Mendelizing mental deficiencies, major psychoses, vocations, ideologies, religions). What personality types, if any, occur in the nonpathological population remains to be researched by sophisticated methods, and cannot be settled by fiat or "dimensional" preference. The intuitive concept of taxonicity is to be explicated by a combination of formal-numerical and causal criteria. Taxometric methods should include consistency tests that provide Popperian risk of strong discorroboration. In social science, latent class methods are probably more useful than cluster algorithms.     

Jungian psychology and pastoral care

This article provides a review of the implications of analytic psychology for pastoral care and the caregiver. Four areas of Jung's thought are examined: (1) his mode of treatment, (2) the process of individuation, (3) his theory of personality types, and (4) his concept of synchronicity. We suggest that Jung's system of thought contains a rich reservoir of insight for the enrichment of pastoral care.     

COMPARISON OF STAFF TRAINING STRATEGIES TO PROMOTE GENERALIZED TEACHING SKILLS

Two studies compared the effectiveness of different strategies for promoting generalization of staff skills in teaching self-care routines to clients with developmental disabilities. In Study 1, 9 direct-care staff members of group homes were trained sequentially through four conditions: (a) the provision of written instructions, (b) performance-based training using a single client program exemplar and simulated clients (single case training), (c) performance-based training using actual developmentally delayed clients as trainees (common stimuli training), and (d) performance-based training using multiple client program exemplars with simulated clients (general case training). The results indicated that staff members did not reach all generalization criteria until general case training was provided. Because staff members had been trained sequentially through several conditions in Study 1, a second study controlled for potential sequence effects. In Study 2, 7 staff members were trained using only the general case strategy after baseline. All staff members reached generalization criteria with only general case training, replicating the findings of Study 1. Together, the two studies demonstrated that the general case training strategy was more effective at promoting generalized training effects across clients, settings, and client programs than other commonly used staff training approaches.     

Examining differential item functioning due to item difficulty and alternative attractiveness

A method for analyzing test item responses is proposed to examine differential item functioning (DIF) in multiple-choice items through a combination of the usual notion of DIF, for correct/incorrect responses and information about DIF contained in each of the alternatives. The proposed method uses incomplete latent class models to examine whether DIF is caused by the attractiveness of the alternatives, difficulty of the item, or both. DIF with respect to either known or unknown subgroups can be tested by a likelihood ratio test that is asymptotically distributed as a chi-square random variable.     

An investigation into the relationship between perceived control,attitude variability and the consumption of two common foods

The study reported here takes its lead from the literatures which emphasize the importance of attitude variability and the role of perceived control over action. Within-person variability and perceptions of control are investigated in the context of people's attitudes towards the consumption of two common foods. The role of attitude ambivalence is also examined. The findings indicate that higher attitude variability is associated with weaker relationships between the components of the theory of reasoned action and that attitude variability is negatively related to perceived control. Moreover, perceived control is shown to be related to different sorts of control problem for different behaviours. It is advocated that a more in-depth assessment of attitude variability and the perceived control construct is merited and that recent calls for more serious examination of attitude ambivalence are well-founded.
