Ethnic‐Related Curricula and Intergroup Attitudes in College: Movement Toward and Away From the In‐Group1

Using a 5‐year longitudinal study, we investigated the long‐term effects of courses with ethnic studies content and courses with Latino or Black professors on university students' intergroup attitudes. We found that these curricular variables significantly affected the intergroup attitudes of students beyond pre‐existing differences in attitudes and beyond other curriculum variables. As expected, we found differences between ethnic groups: White students showed movement toward other groups as a result of these curricular factors, whereas Latino and African American students showed both increased tolerance toward other groups and movement toward the in‐group. The results are discussed in terms of group status differences between the dominant White majority and the stigmatized Latino and Black minority groups.     

Audience-contingent variation in action demonstrations for humans and computers

People may exhibit two kinds of modifications when demonstrating action for others: modifications to facilitate bottom-up, or sensory-based processing; and modifications to facilitate top-down, or knowledge-based processing. The current study examined actors' production of such modifications in action demonstrations for audiences that differed in their capacity for intentional reasoning. Actors' demonstrations of complex actions for a non-anthropomorphic computer system and for people (adult and toddler) were compared. Evidence was found for greater highlighting of top-down modifications in the demonstrations for the human audiences versus the computer audience. Conversely, participants highlighted simple perceptual modifications for the computer audience, producing more punctuated and wider ranging motions. This study suggests that people consider differences in their audiences when demonstrating action.     

The primacy of the public: in support of bioethics commissions as deliberative forums

In a 2004 article, we argued that bioethics commissions should be assessed in terms of their usefulness as public forums. A 2006 article by Summer Johnson argued that our perspective was not supported by the existing literature on presidential commissions, which had not previously identified commissions as public forums and that we did not properly account for the political functions of commissions as instruments of presidential power. Johnson also argued that there was nothing sufficiently unique about bioethics commissions to make the public forum perspective particularly applicable. We respond by arguing that analysis of commissions' work as public forums fits well within the literature on commissions, especially on their agenda-setting functions, and that the political functions of commissions are often compatible with their functioning as public forums. We also demonstrate how the origins and concerns of bioethics make public forum analysis particularly applicable to bioethics commissions.     

Testing beyond words: Using tests to enhance visuospatial map learning

Psychological research shows that learning can be powerfully enhanced through testing, but this finding has so far been confined to memory tasks requiring verbal responses. We explored whether testing can enhance learning of visuospatial information in maps. Fifty subjects each studied two maps, one through conventional study, and the other through computer-prompted tests. For the tests, the subjects were repeatedly presented with the same map with one feature deleted (e.g., a road or a river), and they tried to covertly recall the missing feature and its location. Subjects’ map drawings after 30 min were significantly better for maps learned through tests in comparison with maps learned through the same amount of time devoted to conventional study. These results suggest that the testing effect is not limited to the types of memory that require discrete, verbal responses, and that utilizing covert retrievals may allow the effect to be extended to a variety of complex, nonverbal learning tasks.     

Enhancing learning and retarding forgetting: Choices and consequences

Our research on learning enhancement has been focusing on the consequences for learning and forgetting of some of the more obvious and concrete choices that arise in instruction, including questions such as these: How does spacing of practice affect retention of information over significant retention intervals (up to 1 year)? Do spacing effects generalize beyond recall of verbal materials? Is feedback needed to promote learning, and must it be immediate? Although retrieval practice has been found to enhance learning in comparison with additional study, does it actually reduce the rate of forgetting? Can retrieval practice effects be extended to nonverbal materials? We suggest that as we begin to find answers to these questions, it should become possible for cognitive psychology to offer nonobvious advice that can be applied in a variety of instructional contexts to facilitate learning and reduce forgetting.     

Posture control and complex arm coordination: analysis of multijoint coordinative movements and stability of stance

The authors addressed the interactions between control of bimanual multijoint coordination tasks and posture. Participants (N = 6) performed 8 coordination patterns that differed in degree of complexity by using their bilateral elbows and wrists under 3 scaled motion speeds while standing on 2 force plates. Results indicated that producing complex bimanual multijoint coordinative tasks affected postural sway, thus resulting in an increase of sway activity. Behavioral as well as mechanical factors accounted for the increased disturbance in postural sway. Those findings suggest that performing complex coordination tasks disrupts postural control in normal young adults.     

Body in Mind: The Role of Embodied Cognition in Self-Regulation

We review a growing body of literature that evidences the reciprocal relationship between body and mind, known as embodied cognition. We argue that an embodied mind may serve a functional purpose, aiding in self-regulatory processes. Specifically, we suggest that embodied cognition assists in self-regulation by increasing signal strength, encouraging appropriate goal-relevant action, and incorporating situational constraints to cue appropriate information processing styles. Furthermore, we propose that affect serves as the link between an embodied mind and self-regulatory action. Finally, we situate this research in debates on theories of mind, and we advocate for a highly interactive system that integrates information across modalities.     

Creating a strategy for progress: a contextual behavioral science approach

Behavior analysis is a field dedicated to the development and application of behavioral principles to the understanding and modification of the psychological actions of organisms. As such, behavior analysis was committed from the beginning to a comprehensive account of behavior, stretching from animal learning to complex human behavior. Despite that lofty goal, basic behavior analysis is having a generally harder time finding academic support, and applied behavior analysis has narrowed its focus. In the present paper we argue that both of these trends relate to the challenge of human language and cognition, and that developments within clinical behavior analysis and the analysis of derived relational responding are providing a way forward. To take full advantage of these developments, however, we argue that behavior analysts need to articulate their unique approach to theory, to develop more flexible language systems for applied workers, and to expand their methodological flexibility. This approach, which we term contextual behavioral science, is meant as an evolutionary step that will allow behavior analysis to better capture the center of modern psychological concerns in both the basic and applied areas. Clinical behavior analysis is showing a way forward for behavior analysis to regain its vision as a comprehensive approach to behavior.     

A Longitudinal Test of the Model of Political Conservatism as Motivated Social Cognition

Using data from a longitudinal study of college students, this study assessed the relationships among the threat perceptions of realistic threat and intergroup anxiety, the ideological motives of system justification and social dominance orientation (SDO), and political conservatism. Those who had higher perceptions of realistic threat and intergroup anxiety at the end of their first year of college showed higher levels of system justification and SDO at the end of their second and third years of college, controlling for precollege expressions of each variable. Higher levels of these two ideological motives at the end of students' second and third years of college were associated with more politically conservative attitudes at the end of students' fourth year of college, again controlling for precollege expressions. These longitudinal results are discussed in terms of a model of political conservatism as motivated social cognition.     

Bundling Hume with Kripkenstein

It is argued that the intuition driving Kripke’s famous version of Wittgenstein’s meaning skepticism is precisely the one that prompted Hume to despair of his bundle theory of the self: there are no necessary connections between distinct mental states. This interpretation is shown to throw light on Wittgenstein’s notorious idea that all proofs “create concepts.”

Wittgenstein has invented a new form of skepticism. Personally I am inclined to regard it as the most radical and original skeptical problem that philosophy has seen to date[.] – Saul Kripke
