Responses to symptom induction exercises in panic disorder

Exposure to panic symptoms (interoceptive exposure) is often included as part of treatment for panic disorder (PD), although little is known about the relative effects of particular symptom induction exercises. This study describes responses of individuals with PD and nonclinical controls to 13 standard symptom induction exercises and 3 control exercises. Generally, individuals with PD responded more strongly to symptom induction exercises than did controls. The exercises producing the most fear included spinning, hyperventilation, breathing through a straw, and using a tongue depressor. This study also reports findings regarding specific symptoms triggered by each exercise, the percentage of participants reporting fear during each exercise, and predictors of fear.     

Developmental Study of the Reversed Stroop Effect in Chinese-English Bilinguals

Chinese-English bilinguals in Grades 2, 4, 8, 10, and in college read Chinese and English color words in black or in colored print in the corresponding language. Subjects were more efficient in reading Chinese than English. This superiority effect of reading Chinese gradually decreased as subjects' familiarity with English increased. Furthermore, skilled readers were less susceptible than less skilled readers to the introduction of conflicting colors of ink. This result indicates that the pattern of the reversed Stroop (1935; Dunbar & MacLeod, 1984) effect is related to the proficiency of word processing.     

N400 and P600 or the Role of the ERP Correlates in Sentence Comprehension: Some Applications to the Italian Language

In the present study, event-related brain potentials (ERPs) were applied to the study of language comprehension in the Italian language. The ERPs were recorded from 10 electrodes while the participants read (Experiment 1) or listened (Experiment 2) to sentences containing semantic or syntactic anomalies. Final words that were inconsistent with the sentence context elicited a negative wave at about 400 ms poststimulus that was more concentrated in the posterior sites of the scalp, whereas final words that were incongruous with the grammatical structure (subject-verb nonagreement) elicited a positive wave at about 600 ms poststimulus that was homogeneously distributed on the scalp. The authors found no differences based on the perceptual modality of the stimulus (visual or auditory), nor did they find different ERP correlates as a function of task relevance (explicit-implicit task induction). The available evidence indicated that the ERP response to semantic anomalies was at least partially distinct from the ERP response to syntactic anomalies, and that a syntactic parser is a plausible process included in sentence comprehension. The two semantic and syntactic effects appear as automatic processes of the decoding of the anomalies and also modality-independent processes. Cross-linguistic applications are considered in the general discussion.     

Inducing Hypocrisy to Reduce Prejudicial Responses among Aversive Racists

Might a hypocrisy induction procedure reduce prejudicial behavior among aversive racists? We identified aversive racists as individuals low in explicit prejudice but high in implicit prejudice toward Asians. Results revealed that aversive racists, but not truly low prejudiced participants (i.e., those low in both explicit and implicit prejudice), responded to a hypocrisy induction procedure with increased feelings of guilt and discomfort, compared to those in a control condition. Furthermore, aversive racists, but not low prejudiced participants, responded to a hypocrisy induction procedure with a reduction in prejudicial behavior. These results suggest that consciousness raising might play an important role in motivating aversive racists to reduce their prejudicial behavior.     

A Draft for Unifying Controversies in Philosophy of Science

The basic (negative and positive) methodological maxims of three currents of philosophy of science (logical empiricism, falsificationism, and postpositivism) are formulated. Many of these maxims (stratagems) are controversial, e.g., the stance about the nonsense of metaphysics, and that of its indispensability. The restricted validity of these maxims allows for their unification. Within the framework of most of them there may be a relationship of (synchronic, or diachronic) subordination of the contradicting desiderata. In this vein ten stratagems are formulated. This revised version was published online in August 2006 with corrections to the Cover Date.     

Contemporary Philosophy of Science in Italy: An Overview

The paper analyses the development of some themes in the contemporary philosophy of science in Italy. Section 1 reviews the dabate on the legacy of neopositivism. The spread of the philosophy of Popper is outlined in Section 2, with particular regard to the problem of the vindication of induction. Section 3 deals with the debate on the incommensurability thesis, while Section 4 examines its consequences on the possible relationships between historical and epistemological studies of science. The last section is devoted to one of the most recent trends in the Italian philosophy of science: the resumption of Aristotelian dialectics. This revised version was published online in August 2006 with corrections to the Cover Date.     

A single session of meditation reduces of physiological indices of anger in both experienced and novice meditators

The goal of the present study was to explore how anger reduction via a single session of meditation might be measured using psychophysiological methodologies. To achieve this, 15 novice meditators (Experiment 1) and 12 practiced meditators (Experiment 2) completed autobiographical anger inductions prior to, and following, meditation training while respiration rate, heart rate, and blood pressure were measured. Participants also reported subjective anger via a visual analog scale. At both stages, the experienced meditators’ physiological reaction to the anger induction reflected that of relaxation: slowed breathing and heart rate and decreased blood pressure. Naïve meditators exhibited physiological reactions that were consistent with anger during the pre-meditation stage, while after meditation training and a second anger induction they elicited physiological evidence of relaxation. The current results examining meditation training show that the naïve group’s physiological measures mimicked those of the experienced group following a single session of meditation training.     

Leaping to Conclusions: Why Premise Relevance Affects Argument Strength

Everyday reasoning requires more evidence than raw data alone can provide. We explore the idea that people can go beyond this data by reasoning about how the data was sampled. This idea is investigated through an examination of premise non‐monotonicity, in which adding premises to a category‐based argument weakens rather than strengthens it. Relevance theories explain this phenomenon in terms of people's sensitivity to the relationships among premise items. We show that a Bayesian model of category‐based induction taking premise sampling assumptions and category similarity into account complements such theories and yields two important predictions: First, that sensitivity to premise relationships can be violated by inducing a weak sampling assumption; and second, that premise monotonicity should be restored as a result. We test these predictions with an experiment that manipulates people's assumptions in this regard, showing that people draw qualitatively different conclusions in each case.     

社会认知中归纳推论－演绎推论的不对称性现象

在社会知觉中,人们会较多的根据个体的行为表现推论其所具有的人格特质（归纳推论）,较少根据人格特质来推论个体的行为表现（演绎推论）,Maass将这一现象命名为归纳推论－演绎推论的不对称性,并在西方文化下验证了这一现象。刻板印象在这一不对称性现象中起着调节作用,行为信息与刻板印象是否一致影响了归纳推论,对与刻板印象一致的信息更易做出归纳推论,而对演绎推论没有影响。在不同的文化背景下,归纳推论－演绎推论的不对称性表现存在差异,东方文化下的个体对两种推论过程没有表现出明显的倾向性。本文介绍了这一现象的表现,并总结了产生这一社会现象的内在原因及相关的研究进展。     

Self-Doubt Effects Depend on Beliefs about Ability: Experimental Evidence

Past research has shown negative effects of chronic self-doubt on psychological and performance outcomes. Recent correlational evidence suggests that incremental beliefs about ability ameliorate certain self-doubt effects. The current research examines whether these correlational findings are robust when subjected to experimental testing. In Experiment 1, we manipulated beliefs about ability (incremental vs. entity) and demonstrated that changing beliefs about ability altered responses to self-doubt. For individuals primed with entity beliefs, higher self-doubt was associated with greater nervousness and poorer anagram performance; for individuals primed with incremental beliefs, self-doubt had no significant effects. Experiment 2 was a 2 (manipulated belief: incremental vs. entity) × 2 (self-doubt: doubt induction vs. control) factorial design. The result showed that self-doubt induction lowered self-esteem relative to control when people were primed with entity beliefs but did not affect self-esteem when incremental beliefs were primed. However, Experiment 1 results on affect and performance were not replicated in Experiment 2. Thus, although we provide some causal evidence that inducing individuals to adopt an ability-is-malleable mindset reduces the negative effects of self-doubt, further experimental work is required to study the moderating role of mindsets for self-doubt effects.
