Differential Effects of Strategic Planning on Community Change in Two Urban Neighborhood Coalitions

Community coalitions represent a promising approach for addressing the interrelated and multiply- determined issues affecting urban neighborhoods of concentrated poverty. The literature suggests a number of community processes that may affect coalition efforts to change and improve communities. This study uses an interrupted time-series design to examine the effects of a strategic planning intervention on community change in two urban neighborhoods in the Kansas City metropolitan area. Results showed that strategic planning was associated with increased rates of community change in the two urban neighborhood coalitions. Under appropriate conditions, such as the presence of consistent leadership, strategic planning may be a particularly effective mechanism for stimulating community change and addressing locally-determined goals in urban neighborhoods.

态度是社会心理学研究的重要领域,近年来研究者发现通过说服可以改变个体的态度,所以态度的说服策略成为一个研究的重点。说服包括了陈述论据和事实,推理,做结论和说明所推荐行为方式的积极效果,所有的一切都是为了使受众相信并且按照这种行为方式行事。本文沿着历史的脉络,从不同的角度阐述了各种说服策略的理论解释及其实验研究,并在此基础上叙述了说服策略未来研究趋势。     

Understanding patterns of attitude change: When implicit measures show change, but explicit measures do not

A common assumption in research on attitudes is that indirect measures assess relatively stable implicit attitudes, whereas traditional self-report measures assess more recently acquired explicit attitudes that coexist with old, presumably stable implicit attitudes. This assumption seems difficult to reconcile with research showing experimentally induced changes on implicit but not explicit measures. The present research tested a process-account of such asymmetrical patterns. Specifically, we argue that implicit measures show experimental effects that do not emerge on explicit measures when (a) the pairing of an attitude object with positive or negative valence creates new automatic associations in memory, and, at the same time, (b) the consideration of additional information about the attitude object eliminates the impact of automatic associations on self-reported evaluative judgments. Results from three studies support these predictions. Implications for research on attitude change are discussed.     

Iterated Belief Change and the Recovery Axiom

The axiom of recovery, while capturing a central intuition regarding belief change, has been the source of much controversy. We argue briefly against putative counterexamples to the axiom—while agreeing that some of their insight deserves to be preserved—and present additional recovery-like axioms in a framework that uses epistemic states, which encode preferences, as the object of revisions. This makes iterated revision possible and renders explicit the connection between iterated belief change and the axiom of recovery. We provide a representation theorem that connects the semantic conditions we impose on iterated revision and our additional syntactical properties. We show interesting similarities between our framework and that of Darwiche–Pearl (Artificial Intelligence 89:1–29 1997). In particular, we show that intuitions underlying the controversial (C2) postulate are captured by the recovery axiom and our recovery-like postulates (the latter can be seen as weakenings of (C2)). We present postulates for contraction, in the same spirit as the Darwiche–Pearl postulates for revision, and provide a theorem that connects our syntactic postulates with a set of semantic conditions. Lastly, we show a connection between the contraction postulates and a generalisation of the recovery axiom. Portions of this paper were originally presented at ECAI 2002.     

The Difficulty of Making Psychology Research and Clinical Practice Relevant to Medicine: Experiences and Observations

Psychology and medicine research and practice have demonstrated substantial and unique bodies of knowledge designed to both improve patient care and respond to contemporary health care needs for use of evidence and cost consciousness. At their full potential they represent a significant paradigm shift in healthcare. Despite impressive successes, it is clear that we are just on the cusp of such a change. These findings have had limited impact and penetration into medical practice, particularly outside of academic medicine and large, organized systems of health care, and there are multiple examples of such limitations in various arenas of health care. There also appear to be common themes to such examples which provide us opportunities to consider how psychologists might move things ahead. They also suggest how our unique position in academic medicine can both limit our impact and provide ways of creating continued shifts in the healthcare paradigm. This paper is based in part on the author’s presentation at the Association of Psychologists in Academic Health Centers 3rd National Conference in Minneapolis, Minnesota, May 2007.     

Conditioned reinforcement value and resistance to change

Three experiments examined the effects of conditioned reinforcement value and primary reinforcement rate on resistance to change using a multiple schedule of observing-response procedures with pigeons. In the absence of observing responses in both components, unsignaled periods of variable-interval (VI) schedule food reinforcement alternated with extinction. Observing responses in both components intermittently produced 15 s of a stimulus associated with the VI schedule (i.e., S+). In the first experiment, a lower-valued conditioned reinforcer and a higher rate of primary reinforcement were arranged in one component by adding response-independent food deliveries uncorrelated with S+. In the second experiment, one component arranged a lower valued conditioned reinforcer but a higher rate of primary reinforcement by increasing the probability of VI schedule periods relative to extinction periods. In the third experiment, the two observing-response components provided similar rates of primary reinforcement but arranged different valued conditioned reinforcers. Across the three experiments, observing-response rates were typically higher in the component associated with the higher valued conditioned reinforcer. Resistance to change was not affected by conditioned reinforcement value, but was an orderly function of the rate of primary reinforcement obtained in the two components. One interpretation of these results is that S+ value does not affect response strength and that S+ deliveries increase response rates through a mechanism other than reinforcement. Alternatively, because resistance to change depends on the discriminative stimulus-reinforcer relation, the failure of S+ value to impact resistance to change could have resulted from a lack of transfer of S+ value to the broader discriminative context.     

Dissociations among ABA, ABC, and AAB recovery effects

In a human predictive learning experiment, the strengths of ABA, ABC, and AAB recovery effects after discrimination reversal learning were compared. Initially, a discrimination between two stimuli (X+, Y−) was trained in Context A. During Phase 2, participants received discrimination reversal training (X−, Y+) either in Context A (Group AAB) or in Context B (Group ABA, Group ABC). Testing occurred in the reversal context and in a neutral context (Group AAB, Group ABC) or in the reversal context and in the acquisition context (Group ABA). Recovery effects were similar in ABA and ABC procedures, whereas no AAB recovery effect occurred. Furthermore, the rate of discrimination reversal learning during Phase 2 was unaffected by whether training was conducted in the same or in a different context as initial learning. Results indicate that contextual stimuli are processed before interfering information is presented. These representations, however, do not acquire the ability to control performance.     

Understanding Pamina's recovery: An application of the hermeneutic single‐case efficacy design

This article reports an effectiveness case study of the individual systemic therapy of a 22‐year‐old Portuguese woman with a diagnosis of paranoid personality disorder, conducted in a university‐based clinic in Lisbon, Portugal. Data were analysed using the hermeneutic single‐case efficacy design, a non‐experimental interpretive approach that aims to determine whether change occurred, whether change was due to therapeutic strategies, and what in therapy caused the change. Results indicate that the treatment was effective and that de‐pathologising Pamina's condition and genogram‐based exploration techniques played a crucial role in her recovery.     

Longitudinal Gender Differences in Objectified Body Consciousness and Weight-Related Attitudes and Behaviors: Cultural and Developmental Contexts in the Transition from College

Longitudinal analysis of objectified body consciousness, body esteem, self-acceptance, and weight-related attitudes and behaviors in young adults (115 women and 49 men), who were undergraduates in 1993, tested hypotheses developed from theory on the social construction of gendered bodies and the developmental contexts of the post-college transition. Gender differences in body surveillance, body shame, and body esteem and the relationships between these persisted, whereas the relationship between body esteem and self-acceptance decreased for women and was similar to men at Wave 2. For both women and men, body surveillance and body shame decreased and body esteem increased over time, even though BMI also increased. Men wanted to lose weight at levels similar to women at Wave 2 and were equally likely to exercise to control weight, but they were less likely than women to diet. These results fit both cohort and age-related changes models of body experience for women and men.
