The LogicR4 is obtained by adding the axiom (A vB(AvB) to the modal relevant logicNR. We produce a model theory for this logic and show completeness. We also show that there is a natural embedding of a Kripke model forS4 in eachR4 model structure.We are indebted to several people for discussions relating to the topic of this paper, in particular, Kit Fine, John Slaney, J. M. Dunn, Jacques Riche, M. A. McRobbie, and Jill LeBlanc. We would also like to thank the Automated Reasoning Project for material assistance.

Lever pressing in rats was maintained by continuous and intermittent schedules of food while defecation was monitored. In Experiment 1, reinforcement densities were matched across variable-ratio and variable-interval schedules for three pairs of rats. Defecation occurred in all 3 rats on the variable-ratio schedule and in all 3 rats on the yoked variable-interval schedule. In Experiment 2, fixed-ratio and fixed-interval schedules with similar reinforcement densities maintained lever pressing. Defecation occurred in 3 of 4 rats on the fixed-ratio schedule and in 4 of 4 rats on the fixed-interval schedule. Almost no defecation occurred during continuous reinforcement in either experiment. These results demonstrate that defecation may occur during both ratio and interval schedules and that the inter-reinforcement interval is more important than the behavioral requirements of the schedule in generating schedule-induced defecation. 相似文献

Toward a Process Analysis of Emotions: The Case of Surprise 总被引:1,自引:0,他引:1
Based on an earlier model of the processes elicited by surprising events, the present studies provide evidence for one of these processes, the evaluation of the surprising event's relevance for ongoing activities (action-relevance check). The central prediction tested was that, if unexpected events elicit among other processes an action-relevance check, then response delay on a concurrent task will be more pronounced in a condition where this process is more elaborate and hence takes more time. In accord with this prediction, Experiment 1 found that an unexpected appearance change of the imperative stimulus in a choice reaction time (RT) task caused greater response delay than an equivalent appearance change of a distractor stimulus. Experiment 2 replicated this finding and tested several additional predictions that concerned the effects on response delay of a second appearance change of either the imperative or the distractor stimuli. These predictions, which were also mostly confirmed, were derived by combining the logic underlying the first study with the assumption that once made, appraisals of unexpected events are stored as part of the situational schema and are reused when the same or similar events reoccur leading to an abbreviation of appraisal processes. Experiment 3 once more replicated the basic finding of the previous studies and ruled out a possible alternative explanation. It is suggested that the proposed RT method of process verification may be of broader interest as a tool to study appraisal processes in emotion. 相似文献

Modern ethics has been shaped by two dominant philosophical assumptions: (1) that there can be no theoretical knowledge of God, i.e., denial of metaphysics, and (2) that moral claims can be redeemed independently of theistic affirmations, i.e., morality does not require theism. These assumptions have influenced much of modern theological ethics. Yet, insofar as theological ethics accepts that morality does not require any explicit or implicit religious beliefs, it affirms that a secularistic morality is possible. But this affirmation is directly at odds with the essence of theism, namely, that God is the source and end of all things, including the moral life. By accepting the dominant consensus, therefore, theological ethics undermines its fundamental theistic claim. Focusing on James Gustafson's theocentric ethics, I seek to show the price that theological ethics pays for subscribing to the dominant consensus. I argue that: (1) Gustafson embraces an inconsistent self-understanding, which undermines his theocentric claim, (2) this is due to his dismissal of metaphysics, and (3) his theocentric ethic would be more compelling if formulated in terms of Whitehead's process metaphysics. 相似文献

A sexual sadist was treated by an olfactory aversion procedure for eight weeks. Pre-treatment assessment of sexual arousal showed high levels of response to sadistic stimuli as well as high arousal to non-sadistic heterosexual stimuli. In treatment the inhalation of the gas of an odoriferous chemical agent, valeric acid, was paired with slide presentations of sadistic materials while penile erection was monitored. The aversive stimulus immediately and permanently suppressed the response for the duration of treatment. In separate measurement sessions, with valeric acid absent, deviant response remained suppressed and nondeviant response was unaffected. Post-treatment reassessment revealed very low levels of response to sadistic stimuli. Follow-up sessions showed that the deviant response was absent eight months following the conclusion of treatment. 相似文献

Counselor education literature acknowledges the difficulty of skill maintenance but offers few solutions. A review of related areas was conducted to provide direction in developing maintenance strategies. Four domains were considered: maintenance in behavior modification, behavioral self-control, the traditional maintenance mechanisms of feedback, supervision, and observational media, and self-supervisory programs. A self-supervisory program that applies the procedures of behavioral self-control to specific helping behavior that is identifiable on audiotape or videotape is advocated. 相似文献

Recruiting help from mentors and other potential helpers is a promising strategy for helping disadvantaged and minority youths meet their personal and educational goals. Three African-American high school seniors participated in a project designed to evaluate the effectiveness of training procedures that would allow them to ask for help in attaining educational and other personal goals. A behavioral training procedure that included instructional materials, role-play practice, praise, and feedback was used. Targeted skills included goal setting and 30 responses involved in the process of meeting with a potential helper. Role-play situations were used to evaluate participants' help-recruiting skills before and after training. Participants increased their help-recruiting skills from an average of 38% during baseline, to an average of 75% after training. Self-reported measures of goal attainment suggested that the students benefited from the training. Implications for mentoring programs designed to increase minority students' opportunities to reach educational goals were discussed. 相似文献
