Reinforcement magnitude effects in first- and second-order conditioning of directed action

Three experiments investigated the effects of reinforcement magnitude on conditioned key pecking in pigeons. Experiment 1, which included between-groups and within-subject designs, yielded significant effects of unconditioned stimulus (US) magnitude on the within-conditioned stimulus (CS) distribution of key pecks and on choice behavior, but no effect on the overall rate of key pecking. Experiment 2 employed a larger US-magnitude difference in a within-subject design. This manipulation resulted in differential rates of key pecking as well as a significant choice effect and differential within-CS key-peck distributions. A second-order conditioning procedure was used in Experiment 3, in which diffuse, visual stimuli (S1's) served as Pavlovian reinforcers for two key-light S2's. The S1 previously paired with a large US was more effective in conditioning second-order key-peck behavior to an S2 than was the S1 paired with a small US. The results of these experiments demonstrate that the associative effects of US magnitude can be expressed in the strength of CS-directed motor responding. The distinctive within-CS key-peck distributions in first-order conditioning suggests an interaction between CS- and US-directed responses.     

Sex-role identity as a moderator of the polarization effect in person perception

Male and female subjects with different sex-role identities (Androgynous, Masculine, Feminine, Undifferentiated) rated likability of male and female stimulus persons in the impression formation paradigm. Under certain conditions all the female subjects and feminine males manifested a polarization effect; that is, they made more polar ratings of opposite-sexed stimulus persons in contrast to same-sexed stimulus persons. On the other hand, under certain conditions Masculinetyped males rated male stimulus persons more negatively than female stimulus persons. Results were discussed in terms of moderating effects on the polarization phenomenon and possible explanatory mechanisms.     

Revisiting Religious Ethics as Field and Discipline

Returning to John P. Reeder's 1978 essay on “Religious Ethics as a Field and Discipline,” this essay explores debates surrounding the original intentions for the Journal of Religious Ethics (JRE) and for the field of religious ethics, as these have played out over the decades among an influential group of scholars involved with the JRE since its inception: Arthur Dyck, Ronald Green, Stanley Hauerwas, and Jeffrey Stout. While the JRE and its founding mission are in need of ongoing critique and transformation, we might well still affirm the journal's ongoing importance as a site for the negotiation of a commons, the identification of possibilities for shared life, imagined beyond exclusion and domination.     

DEMOCRATIC VIRTUE, COMPARATIVE ETHICS, AND CONTEMPORARY ISLAM

This essay illustrates the kind of moral analysis Jeffrey Stout advocates in Democracy and Tradition by way of examining a conversation among Muslims that took place between June and December 2002. Their debate centers on al‐Qaída's legitimacy as God's chosen defender of Islam, which is called into question due to the tension between al‐Qaída's military tactics and the concepts of honorable combat held within the Islamic tradition. This giving and taking of reasons in both defense and detraction of al‐Qaída's tactics demonstrates the living reality of Islamic tradition—the ongoing process of striving to discern God's will in light of communal agreements about the authority of certain texts and the validity of established rules for interpreting them.     

FORMATION,GRACE, AND PNEUMATOLOGY: Or,Where's the Spirit in Gregory's Augustine?

Eric Gregory's Politics and the Order of Love takes up an audacious project: enlisting Saint Augustine in order to “help imagine a better liberalism.” This article first provides a summary of Gregory's argument, focusing on his emphasis on love as a “motivation” for neighborly care, and hence democratic participation. This involves tracing the theme of motivation in the book, which is tied to his articulation of liberal perfectionism and an emphasis on civic virtue. In conclusion I raise the question of whether his project has ignored a key aspect of Augustine's account of love, namely, the role of the Holy Spirit, thereby demarcating the limits of Gregory's “rational reconstruction” of Augustine.     

Syntactical Constraints on Definitions

This essay considers arguments for and against syntactical constraints on the proper formalization of definitions, originally owing to Alfred Tarski. It discusses and refutes an application of the constraints generalized to include a prohibition against not only object‐place but also predicate‐place variables in higher‐order logic in a criticism of a recent effort to define the concept of heterologicality in a strengthened derivation of Grelling's paradox within type theory requirements. If the objections were correct, they would offer a more general moral for the proper formal definition of terms in philosophical logic. The criticism nevertheless seems mistaken both in the substance and specific application with respect to legitimate synctactical constraints on definitions of key concepts in the case of Grelling's paradox. As such, the critique provides no justification for overturning previous conclusions concerning the possibility of resurrecting a type‐observant version of Grelling's heterologicality paradox.     

Some sources and consequences of career exploration

The present research investigated (a) factors that may influence participation in career exploration, and (b) the role of anxiety in the exploration process. The sample consisted of 161 undergraduate college students. Work-role salience (the importance of work in a person's life) was positively related to participation in self-related and work-related exploration. Self-related exploration was positively related to satisfaction with the occupational decision of low anxiety students and was negatively related to satisfaction among high anxiety students. Furthermore, dissatisfaction with an occupational decision was more likely to stimulate future work-related exploration for low anxiety students than for highly anxious students. The implications of these findings for the career exploration process were discussed.
