Activation of response codes by relevant and irrelevant stimulus information

Single-route models attribute stimulus-response compatibility effects to the difficulty of translation from stimulus to response. Dual-route models propose that compatibility effects reflect in part an additional direct, or automatic, activation route. Selected findings from three lines of research are reported that converge to provide evidence consistent with the view that the automatic activation route plays a role in compatibility effects. The data suggest that the activation produced via this route by relevant stimulus attributes influences response selection only when all mappings of stimuli to responses are known to be compatible.     

TRACING A TRAJECTORY

Abstract. Theology and ethics intersect with sciences at different points depending upon whether the scholars involved are interested in, for example, general epistemological issues or practical moral judgments. The intersection affects theology and ethics in different ways, depending upon various commitments or resistances on the part of theologians. The author surveys his own writings to show how openness to the sciences has had an impact on various phases of his work and what issues remain somewhat unresolved.     

BURHOE AND SHAPLEY: A COMPLEMENTARITY OF SCIENCE AND RELIGION

Abstract. The development of Ralph Wendell Burhoe's philosophy of religion and science occurred in the shadow of the continuing dialogue about the place of science in American society. Like his friend and mentor, Harvard astronomer Harlow Shapley, Burhoe was distressed and intrigued by the troubled postwar relations between science and religion. Unlike Shapley, however, Burhoe sought to create a new modernism, a blend of religion and science that would allow each to develop and complement the other.     

Assessing mental capacity and susceptibility to undue influence

Clinicians are commonly asked to participate in the determination of an individual's mental capacity and susceptibility to undue influence. Vague statutory definitions and lack of operational criteria for both determinations have contributed to inconsistency in the quality and usefulness of expert input to these determinations. Questionnaire responses of 119 probate judges from the U.S. indicate that this input is quite influential despite the problems mentioned above. This paper presents and discusses the judges' views on selected procedural and conceptual aspects of expert evaluation and testimony.     

CAN MULTI-SOURCE FEEDBACK CHANGE PERCEPTIONS OF GOAL ACCOMPLISHMENT,SELF-EVALUATIONS,AND PERFORMANCE-RELATED OUTCOMES? THEORY-BASED APPLICATIONS AND DIRECTIONS FOR RESEARCH

Multi-source feedback extends traditional performance appraisal by collecting information from subordinates, peers, supervisors, and customers. Ratees often receive the results along with normative data and self-ratings. This paper explores how multi-source feedback goes beyond traditional performance appraisal by providing ratees with comparative information. Focusing on person perception and information processing dynamics, this paper develops a model and associated propositions to explain the effects of multi-source feedback on perceptions of goal accomplishment, re-evaluation of self-image, and changes in outcomes such as goals, development, behavior, and performance. Moderators of relationships between the major components in the model include individual difference variables (self-image, feedback seeking, self-monitoring, task-specific self-efficacy, and impression management) and situational conditions (the content and process of multi-source feedback and organizational performance standards). Issues of research and practice intended to improve understanding and effectiveness of multi-source feedback are discussed.     

AN EMPIRICAL INVESTIGATION OF THE PREDICTORS OF EXECUTIVE CAREER SUCCESS

This study examined the degree to which demographic, human capital, motivational, organizational, and industrylregion variables predicted executive career success. Career success was assumed to comprise objective (pay, ascendancy) and subjective (job satisfaction, career satisfaction) elements. Results obtained from a sample of 1,388 U.S. executives suggested that demographic, human capital, motivational, and organizational variables explained significant variance in objective career success and in career satisfaction. Particularly interesting were findings that educational level, quality, prestige, and degree type all predicted financial success. In contrast, only the motivational and organizational variables explained significant amounts of variance in job satisfaction. These findings suggest that the variables that lead to objective career success often are quite different from those that lead to subjectively defined success.     

ACHIEVING AND MAINTAINING COMPLIANCE WITH THE KETOGENIC DIET

The ketogenic diet, a treatment for intractable epilepsy, is rarely initiated because it requires strict compliance with a diet that is perceived to be unpalatable. In a case study of a 15-year-old girl with uncontrolled epilepsy, we used a stimulus-choice procedure to assess relative preferences of 33 foods from the diet and to develop two treatments based on Premack's principle. The results of a multielement analysis showed that both treatments increased dietary compliance. Compliance was maintained with generalization of treatment across settings, and was associated with a 40% reduction in seizures.     

Predicting and scaling hens' preferences for topographically different responses

Six hens were exposed to several concurrent (second-order) variable-interval schedules in which the response requirements on the alternatives were varied. The response requirements were one key peck versus five key pecks, one key peck versus one door push, and five key pecks versus one door push. Response- and time-allocation ratios undermatched the obtained reinforcement ratios but were well described by the generalized matching law. Time and response bias estimates from two pairs of response requirements were used to predict bias in the third pairing. The predicted values were close to those obtained; this result supports the notion that both numerically and topographically different responses act as constant sources of bias within the generalized matching law. The differences between the response and time biases could be accounted for by the different times needed to complete each response requirement. The results also suggest that the door push is a useful operant for research with domestic hens.     

Maximizing internal and external validity in MMPI malingering research: a study of a military population

The authors investigated the effectiveness of various commonly used Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1943) indices of exaggeration and malingering in detecting suspected malingering in a military sample of 121 enlisted men. To maximize external validity, only men undergoing psychological evaluation were used as participants. Forty-one participants were identified as suspected malingerers through multiple criteria and were contrasted with schizophrenic-spectrum and clinic outpatient groups. To improve internal validity, the 41 suspected malingering participants were asked to retake the test without exaggerating. Results revealed that there were many false positives and fewer, but nonetheless many, false negatives with standard malingering indices. It appeared that the Gough Dissimulation scale (Gough, 1947) might hold the most promise as a measure of malingering, but other scales are also useful. Individual comparisons between different samples and implications for MMPI-2 (Butcher et al., 1989) are presented.
