Humean dispositionalism

Humean metaphysics is characterized by a rejection of necessary connections between distinct existences. Dispositionalists claim that there are basic causal powers. The existence of such properties is widely held to be incompatible with the Humean rejection of necessary connections. In this paper I present a novel theory of causal powers that vindicates the dispositionalist claim that causal powers are basic, without embracing brute necessary connections. The key assumptions of the theory are that there are natural types of causal processes, and that manifestations of powers are identified with certain kinds of causal processes. From these assumptions, the modal features of powers are explained in terms of internal relations between powers themselves and the process-types in which powers are manifested.     

The effect of psychologists’ disclosure of personal religious background on prospective clients

The present study explored the relation of religious coping and spirituality to adjustment and psychological distress in urban early adolescents. The participants were 76 sixth-, seventh-, and eighth-grade students attending Catholic day schools in the New York City area. They completed a set of self-report measures assessing religious coping, daily spiritual experiences, positive and negative affect, life satisfaction, and psychological distress. Correlational and regression analyses found positive religious coping and daily spiritual experiences to be associated with positive affect and life satisfaction, while negative religious coping was associated with negative affect and psychological distress. The relations generally were more robust among males, and their overall robustness decreased with age. Implications of the findings for research and clinical practice are offered to address the gap (compared to adults) in the literature on youth religious coping.     

A two year follow-up study of public vocational school graduates

A 2-year follow-up study of public vocational school graduates revealed that the graduates successfully obtained jobs. Among the factors deemed important by both graduates and employer, communication skills were mentioned as vital. Counseling and preparation in getting along with others were perceived by graduates as inferior. Except for cooperative work program graduates, adjustment to an 8 hr workday caused some problems.     

Using Judgments to Understand Decoy Effects in Choice

Students were presented choice triads from several different domains, with alternatives described along two dimensions. In Experiment 1, the decoy alternative in each set was dominated by only one of the two other alternatives in the set. In Experiment 2, the decoy alternative was dominated by both of the other alternatives in the set. Within different blocks of trials, participants rated (a) overall attractiveness of each alternative, (b) importance of the different dimensions, (c) attractiveness of each attribute value, and (d) the justifiability of each alternative. Significant effects of manipulating the decoy were found for justifiability ratings and value ratings, with these combining to predict effects on attractiveness ratings. Results argued against a weight-change model of decoy effects and supported value-shift and value-added models.     

Testing alternative explanations of phantom decoy effects

Phantom decoys are alternatives that asymmetrically dominate a targeted alternative and yet lead to increased selection of the target when the decoy is declared to be unavailable. This effect is difficult to explain within most standard theoretical accounts of decoy effects. The current experiments tested between three explanations of this effect: (1) the relative advantage model based on loss aversion, (2) similarity substitution, and (3) range weighting. In Experiment 1, participants were presented trinary choice sets, with half of the sets containing a phantom decoy in one of five possible locations within the attribute space. Phantom decoy effects were robust across all decoy locations but one, and the pattern of effects most closely corresponded to predictions of the relative advantage model. Experiment 2 used a within‐subjects manipulation of the five phantom decoy locations. The overall pattern of effects most closely corresponded to predictions from the relative advantage model, as did the pattern for the group of participants who exhibited the strongest phantom decoy effects.
