Complexity of categorical syllogisms: An integration of two metrics

The complexity of categorical syllogisms was assessed using the relational complexity metric, which is based on the number of entities that are related in a single cognitive representation. This was compared with number of mental models in an experiment in which adult participants solved all 64 syllogisms. Both metrics accounted for similarly large proportions of the variance, showing that complexity depends on the number of categories that are related in a representation of the combined premises, whether represented in multiple mental models, or by a single model. This obviates the difficulty with mental models theory due to equivocal evidence for construction of more than one mental model. The “no valid conclusion” response was used for complex syllogisms that had valid conclusions. The results are interpreted as showing that the relational complexity metric can be applied to syllogistic reasoning, and can be integrated with mental models theory, which together account for a wide range of cognitive performances.     

Effects of Age,Sex, and Income Level on Sex-Role Differentiation in Preschoolers

Sex-role differentiation in 337 three-, four-, and five-year-old girls and boys, approximately equally divided into lower-and middle-income groups, was measured by five sex-role tests. A composite z score was also used for increased reliability. The study was replicated in order to investigate the reliability of the measures. The results showed that sex and, to a partial degree, age, had significant effects, but income level had little effect on sex-role differentiation. A factor analysis of the sex-role tests is also discussed.     

An Applied Example of Pooled Time Series Analysis: Cardiovascular Reactivity to Stressors in Children With Autism

The advent of telemetric devices that sample data extensively over time has facilitated single subject or idiographic research to intensively study a single person over time. One of the challenges of idiographic research is combining single subject results to determine generalizability across subjects. This article demonstrates the first behavioral science application of pooled time series analysis, an extension of time series analysis that allows for the testing of between-person effects. The analysis used cardiovascular data gathered from 4 children with autism between the ages of 10 and 20 while exposed to 6 experimentally manipulated environmental stressors. A pooled time series analysis using the general transformation approach identified 1 general (a difficult learning task) and 3 specific stressors (exposure to a loud noise, unstructured time, and eating a preferred food) across the 4 participants. This application of pooled time series analysis demonstrates the challenges and potential for this method to address the issue of generalizability when using an idiographic research approach in the behavioral sciences.     

Mental imagery as an emotional amplifier: application to bipolar disorder

Cognitions in the form of mental images have a more powerful impact on emotion than their verbal counterparts. This review synthesizes the cognitive science of imagery and emotion with transdiagnostic clinical research, yielding novel predictions for the basis of emotional volatility in bipolar disorder. Anxiety is extremely common in patients with bipolar disorder and is associated with increased dysfunction and suicidality, yet it is poorly understood and rarely treated. Mental imagery is a neglected aspect of bipolar anxiety although in anxiety disorders such as posttraumatic stress disorder and social phobia focusing on imagery has been crucial for the development of cognitive behavior therapy (CBT).In this review we present a cognitive model of imagery and emotion applied to bipolar disorder. Within this model mental imagery amplifies emotion, drawing on Clark's cyclical panic model [(1986). A cognitive approach to panic. Behaviour Research and Therapy, 24, 461–470]. We (1) emphasise imagery's amplification of anxiety (cycle one); (2) suggest that imagery amplifies the defining (hypo-) mania of bipolar disorder (cycle two), whereby the overly positive misinterpretation of triggers leads to mood elevation (escalated by imagery), increasing associated beliefs, goals, and action likelihood (all strengthened by imagery).Imagery suggests a unifying explanation for key unexplained features of bipolar disorder: ubiquitous anxiety, mood instability and creativity. Introducing imagery has novel implications for bipolar treatment innovation - an area where CBT improvements are much-needed.     

Transitive and pseudo-transitive inferences

Given that A is longer than B, and that B is longer than C, even 5-year-old children can infer that A is longer than C. Theories of reasoning based on formal rules of inference invoke simple axioms ("meaning postulates") to capture such transitive inferences. An alternative theory proposes instead that reasoners construct mental models of the situation described by the premises in order to draw such inferences. An unexpected consequence of the model theory is that if adult reasoners construct simple models of typical situations, then they should infer transitive relations where, in certain cases, none exists. We report four studies corroborating the occurrence of these "pseudo-transitive" fallacies. Experiment 1 established that individuals' diagrams of certain non-transitive relations yield transitive conclusions. Experiment 2 showed that these premises also give rise to fallacious transitive inferences. Experiment 3 established that when the context suggested alternatives to the simple models, the participants made fewer errors. Experiment 4 showed that tense is an important aspect of meaning which affects whether individuals draw transitive conclusions. We discuss the implications of these results for various theories of reasoning.     

Relationships between emotional labor, job performance, and turnover

The present study investigates the relationship between the emotional labor strategies surface acting and deep acting and organizational outcomes, specifically, employees' overall job performance and turnover. Call center employees from two large financial service organizations completed an online survey about their use of surface and deep acting. Their responses were matched with supervisors' ratings of overall job performance and organizational turnover records obtained 9 months later. Results indicate that surface acting is directly related to employee turnover and emotional exhaustion and that the relationship between surface acting and job performance is indirect via employee affective delivery. Deep acting was not linked to these outcomes. Theoretical and practical implications are discussed from the perspective of emotional labor theories.     

Emotional arousal and negative affect in marital conflict: the influence of gender,conflict structure,and demand‐withdrawal

This report covers two studies that examined how spouses' emotional arousal and negative affect in response to marital conflict are shaped by gender, conflict structure, and demand‐withdraw communication. In Study 1, 86 couples participated in a video analogue presentation procedure, and in Study 2, 32 couples participated in an observational methodology. In both studies, spouses' evaluative reports of their emotional arousal and negative affect were collected within two experimental conditions in which either the husband's or the wife's issue was discussed. In both studies, husbands—but not wives—reported lower levels of post‐interaction arousal and negative affect in the wife's issue condition than in the husband's issue condition. In both studies, husbands' as well as wives' level of emotional arousal was positively associated with their level of negative affect. In Study 2, husbands who were less demanding and more withdrawing during marital conflict were less aroused after the discussion. In contrast, wives reported more emotional arousal and negative affect as they were more withdrawing and less demanding, respectively. Copyright © 2005 John Wiley & Sons, Ltd.     

Accounting for the Appeal to the Authority of Experts

Work in Argumentation Studies (AS) and Studies in Expertise and Experience (SEE) has been proceeding on converging trajectories, moving from resistance to expert authority to a cautious acceptance of its legitimacy. The two projects are therefore also converging on the need to account for how, in the course of complex and confused civic deliberations, nonexpert citizens can figure out which statements from purported experts deserve their trust. Both projects recognize that nonexperts cannot assess expertise directly; instead, the nonexpert must judge whether to trust the expert. But how is this social judgment accomplished? A normative pragmatic approach from AS can complement and extend the work from SEE on this question, showing that the expert’s putting forward of his view and “bonding” it with his reputation for expertise works to force or “blackmail” his audience of citizens into heeding what he says. Appeals to authority thus produce the visibility and accountability we want for expert views in civic deliberations.     

Relationships between right-wing authoritarianism, terrorism threat, and attitudes towards restrictions of civil rights: a comparison among four European countries

The present study tested the role of right-wing authoritarianism (RWA), terrorist threat, and sociopolitical 'climate' as predictors of support for governmental anti-terrorism policies and actions. Two dimensions of analysis were defined: the presence versus absence of al-Qaeda attacks, and adherence to surveillance versus anti-surveillance mainstream politics. In order to study the influence of these two contextual dimensions on the expression of attitudes, we selected four European countries that fall into these two dimensions--Poland, Belgium, Spain, and the UK. Results from our study provide support for the contention that attitudes towards restrictions of civil rights are related to RWA independently of the cultural context. Moreover, in the UK sample, we found that the threat of terrorism increases acceptance of limitations of civil liberties, but only among people who hold authoritarian beliefs. However, in Spain, the other country that experienced terrorist attacks, this moderation effect was not found which is interpreted in terms of differences in the sociopolitical climate in both countries. As predicted, we did not find such moderation effect in countries in which threat is relatively low (Poland and Belgium). The results are discussed with reference to the conceptual framework based on the importance of fear experiences, security-focused policies, as well as the specific cultural context in the study of reaction to terrorist threat.
