Sea lions and equivalence: expanding classes by exclusion

Experiments have shown that human and nonhuman subjects are capable of performing new arbitrary stimulus-stimulus relations without error. When subjects that are experienced with matching-to-sample procedures are presented with a novel sample, a novel comparison, and a familiar comparison, most respond by correctly selecting the novel comparison in the presence of the new sample. This exclusion paradigm was expanded with two California sea lions that had previously formed two 10-member equivalence classes in a matching-to-sample procedure. Rather than being presented with a novel sample on a given trial, the sea lions were presented with a randomly selected familiar member of one class as the sample. One of the comparisons was a randomly selected familiar member of the alternative class, and the other was a novel stimulus. When required to choose which comparison matched the sample, the subjects reliably rejected the familiar comparison, and instead selected the unfamiliar one. Next, the sea lions were presented with transfer problems that could not be solved by exclusion; they immediately grouped the new stimuli into the appropriate classes. These findings show that exclusion procedures can rapidly generate new stimulus relations that can be used to expand stimulus classes.

How (and where) does moral judgment work?

Moral psychology has long focused on reasoning, but recent evidence suggests that moral judgment is more a matter of emotion and affective intuition than deliberate reasoning. Here we discuss recent findings in psychology and cognitive neuroscience, including several studies that specifically investigate moral judgment. These findings indicate the importance of affect, although they allow that reasoning can play a restricted but significant role in moral judgment. They also point towards a preliminary account of the functional neuroanatomy of moral judgment, according to which many brain areas make important contributions to moral judgment although none is devoted specifically to it.     

Use of a lag differential reinforcement contingency to increase varied selections of classroom activities

The present study evaluated the effects of a lag differential reinforcement contingency on 2 students' activity selections using reversal designs. Results showed that the lag contingency was responsible for promoting increased novel selections, engagement in diverse activities, and greater progress with respect to programmed academic activities.     

The Middle Passage,Trauma and the Tragic Re-Imagination of African American Theology

African American Christian consciousness developed in response to the traumatic field in which African American subjectivity took shape. The expression of the faith in the African American tradition is fundamentally tragic as a consequence. The Middle Passage is the existential and symbolic nodal point of this experience. There is a sense in which African Americans remain very much on the water; marginalized and suspended between worlds. There is a deeper sense in which the African American situation and response reflects the condition of modernity and post-modernity in the sense that it is hardly more than modernity becoming conscious of itself. A thorough examination and exploration of its significance is essential to developing a theology that adequately expresses African American Christian consciousness. This paper is an attempt to lay out, what I think, are some of the basic components of the experience and the bare outlines or orientation of such a theology grounded in it.

Learning from Communities: Overcoming Difficulties in Dissemination of Prevention and Promotion Efforts

The model of prevention science advocated by the Institute of Medicine (P. J. Mrazek & R. J. Haggerty, 1994) has not lead to widespread adoption of prevention and promotion programs for four reasons. The model of dissemination of programs to communities fails to consider community and organizational capacity to implement programs, ignores the need for congruence in values between programs and host sites, displays a pro-innovation bias that undervalues indigenous practices, and assumes a simplistic model of how community organizations adopt innovations. To address these faults, researchers should locate, study, and help disseminate successful indigenous programs that fit community capacity and values. In addition, they should build on theoretical models of how locally developed programs work to make existing programs and polices more effective.     

Community Science: Creating an Alternative Place to Stand?

This article comments on two emerging views of community psychologys approaches to the use of research for responding to social problems in contemporary community contexts – (a) the formation of a new field of community science, or (b) the updating of community psychology research traditions. If community science is to become established as a field related to community psychology, its proponents will need to agree upon conventions of epistemology, foci of interest, methods, and standards by which its work can be judged so that it can be distinguished from other human sciences. These articles provide early sketches for what community science might be. However, as noted in this commentary, we need to heed signs of concern about community psychologys continued relevance in public discourse regarding the analysis of and responses to social problems. While this special issue offers some promising responses to the concern of what the field can contribute, the field would be well served if we broaden our dialogue about a renewal of community psychologys commitment to social justice and the need for its perspectives in the practice of research that seeks to address community-based issues in the early 21st century.
