The Rationale Behind Revision-Rule Semantics

According to Gupta and Belnap, the “extensional behavior” of ‘true’ matches that of a circularly defined predicate. Besides promising to explain semantic paradoxicality, their general theory of circular predicates significantly liberalizes the framework of truth-conditional semantics. The authors’ discussions of the rationale behind that liberalization invoke two distinct senses in which a circular predicate’s semantic behavior is explained by a “revision rule” carrying hypothetical information about its extension. Neither attempted explanation succeeds. Their theory may however be modified to employ a relativized notion of extension. The resulting contextualist semantics for ‘true’ construes circularity as a pragmatic phenomenon.     

Cognitive-Behavior Therapy for Reduction of Persistent Anger

Although persistent anger is not represented in DSM-IV as a psychiatric disorder, it is nevertheless a significant clinical problem. Based on our experience with both research and clinic patients from a diverse urban population, and drawing on methods utilized by others, we have refined and elaborated several treatment strategies that appear useful for anger reduction. The strategies derive from a counterconditioning treatment model: patients are exposed (either naturally or by design) to situations that may evoke anger, while they apply physiological, cognitive, and/or behavioral methods that can dampen the habitually angry response. The specific anger-reduction methods include: applied muscle relaxation, cognitive reappraisal, inhibition of overresponding, and reversal of underresponding (through acquisition of effective communication and problem-solving skills). Preliminary evidence is presented indicating that anger patients experience significant reduction in the intensity, duration, and frequency of anger reactions after completing 12 sessions of therapy utilizing these anger-reduction methods.     

From stereotype threat to stereotype threats: implications of a multi-threat framework for causes, moderators, mediators, consequences, and interventions.

More than 100 articles have examined the construct of stereotype threat and its implications. However, stereotype threat seems to mean different things to different researchers and has been employed to describe and explain processes and phenomena that appear to be fundamentally distinct. Complementing existing models, the authors posit a Multi-Threat Framework in which six qualitatively distinct stereotype threats arise from the intersection of two dimensions--the target of the threat (the self/one's group) and the source of the threat (the self/outgroup others/ingroup others). The authors propose that these threats constitute the core of the broader stereotype threat construct and provide the foundation for understanding additional, as of yet uncharacterized, stereotype threats. The proposed threats likely differentially peril those with different stigmatizable characteristics, have different eliciting conditions and moderators, are mediated by somewhat different processes, are coped with and compensated for in different ways, and require different interventions to overcome.     

The Time Course of Verb Processing in Dutch Sentences

The verb has traditionally been characterized as the central element in a sentence. Nevertheless, the exact role of the verb during the actual ongoing comprehension of a sentence as it unfolds in time remains largely unknown. This paper reports the results of two Cross-Modal Lexical Priming (CMLP) experiments detailing the pattern of verb priming during on-line processing of Dutch sentences. Results are contrasted with data from a third CMLP experiment on priming of nouns in similar sentences. It is demonstrated that the meaning of a matrix verb remains active throughout the entire matrix clause, while this is not the case for the meaning of a subject head noun. Activation of the meaning of the verb only dissipates upon encountering a clear signal as to the start of a new clause.     

Memory issues pertaining to social marketing messages about behavior enactment versus non-enactment

This article examines efficiency issues pertaining to social marketing messages about behavior enactment (e.g., smoker) vs. non-enactment (e.g., nonsmoker). Building on a wealth of psycholinguistics research, we posit that underlying differences in the processing and storage of word concepts with affixal negations affect learning and memory for these concepts (i.e., associations with non-enactment concepts will be harder to learn and remember than associations with enactment concepts). Two experiments support our predictions, suggesting that messages about enactment will demonstrate superior efficiency. Implications of study findings are discussed in terms of possibilities for improving the efficiency of social marketing messages about non-enactment.     

Distractor devaluation requires visual working memory

Visual stimuli seen previously as distractors in a visual search task are subsequently evaluated more negatively than those seen as targets. An attentional inhibition account for this distractor-devaluation effect posits that associative links between attentional inhibition and to-be-ignored stimuli are established during search, stored, and then later reinstantiated, implying that distractor devaluation may require visual working memory (WM) resources. To assess this, we measured distractor devaluation with and without a concurrent visual WM load. Participants viewed a memory array, performed a simple search task, evaluated one of the search items (or a novel item), and then viewed a memory test array. Although distractor devaluation was observed with low (and no) WM load, it was absent when WM load was increased. This result supports the notions that active association of current attentional states with stimuli requires WM and that memory for these associations plays a role in affective response.     

Skill transfer through goal-driven representation mapping

In this paper, we present an approach to transfer that involves analogical mapping of symbols across different domains. We relate this mechanism to Icarus, a theory of the human cognitive architecture. Our system can transfer skills across domains hypothesizing maps between representations, improving performance in novel domains. Unlike previous approaches to analogical transfer, our method uses an explanatory analysis that compares how well a new domain theory explains previous solutions under different mapping hypotheses. We present experimental evidence that the new mechanism improves transfer over Icarus’ basic learning processes. Moreover, we argue that the same features which distinguish Icarus from other architectures support representation mapping in a natural way and operate synergistically with it. These features enable our analogy system to translate a map among concepts into a map between skills, and to support transfer even if two domains are only partially analogous. We also discuss our system’s relation to other work on analogy and outline directions for future research.     

Perfectionism, beliefs, and adjustment in dating relationships

Two studies examined the extent to which dimensions of perfectionism are associated with indices of relationship beliefs, behaviors, and dyadic adjustment. In Study 1, 69 students in dating relationships completed the Multidimensional Perfectionism Scale (MPS) and a multidimensional measure of relationship beliefs. In addition, partici-pants completed self-report measures of positive and negative relationship behaviors, and global measures of liking and loving. In Study 2, 91 students in dating relation-ships completed a battery of measures including the MPS and scales assessing perfec-tionism cognitions and perfectionistic self presentation. They also completed mea-sures of dyadic adjustment and limerence (i.e., intense, obsessive low with fears of rejection). Collectively, the findings indicated that individuals with high levels of self-oriented perfectionism and other-oriented perfectionism have stronger relationship beliefs in the areas of communication, trust, and support, suggesting that these perfec-tionists have high relationship standards in these particular areas. Although social prescribed perfectionism had little association with specific relationship beliefs, so-cially prescribed perfectionism was associated with a tendency to display destructive relationship responses (i.e., exit, neglect, and insensitivity), lower dyadic adjustment, and various aspects of limerence, including obsessive preoccupations and emotional dependence on the dating partner. Perfectionistic self-presentation and perfectionism cognitions were also linked with aspects of limerence. The results suggest that inter-personal aspects of perfectionism are associated with self-defeating tendencies in dating relationships.
