Irrational and Metacognitive Beliefs Mediate the Relationship Between Content Beliefs and GAD Symptoms: A Study on a Normal Population

Cognitive Behavioral Therapy (CBT), Rational Emotive Behavior Therapy (REBT) and Metacognitive Therapy (MCT) models show both similarities and differences in conceptualizing anxiety. This work assumes that REBT’s irrational and MCT’s metacognitive beliefs play a mediation role while CBT’s disorder specific content beliefs act as triggers. This hypothesis is tested using a regression model in which metacognitive and irrational beliefs play a mediation role while content disorder beliefs are independent variables. This paper applied this model to generalized anxiety disorder (GAD), a psychiatric diagnosis in which anxiety is the major feature. In GAD, the specific content beliefs are negative problem orientation and intolerance of uncertainty. Therefore, 149 non clinical subjects completed 4 self-report questionnaires: the Negative Orientation to the Problems Questionnaire and the Intolerance of Uncertainty Scale as measures for content cognitive beliefs, the Attitudes and Beliefs Scale for irrational beliefs, and the Metacognitive Questionnaire 30 Items Version for metacognitive beliefs. The generalized anxiety disorder questionnaire was chosen in order to measure anxiety as dependent variable. Regression analyses confirmed that irrational and metacognitive beliefs mediate the relation between cognitive content beliefs and GAD. We clinically interpret mediation as a second level regulation.     

Recognition of all basic emotions varies in accuracy and reaction time: A new verbal method of measurement

To study different aspects of facial emotion recognition, valid methods are needed. The more widespread methods have some limitations. We propose a more ecological method that consists of presenting dynamic faces and measuring verbal reaction times. We presented 120 video clips depicting a gradual change from a neutral expression to a basic emotion (anger, disgust, fear, happiness, sadness and surprise), and recorded hit rates and reaction times of verbal labelling of emotions. Our results showed that verbal responses to six basic emotions differed in hit rates and reaction times: happiness > surprise > disgust > anger > sadness > fear (this means these emotional responses were more accurate and faster). Generally, our data are in accordance with previous findings, but our differentiation of responses is better than the data from previous experiments on six basic emotions.     

The where of bodily awareness

汉字刺激质量与语义启动间的交互作用

本研究探讨汉字刺激质量与语义启动的相互作用,深入考察汉字识别的内在机制。实验采用真假字判断范式,实验1使用语义相关词对比率较高的实验材料,实验2使用语义相关词对比率较低的实验材料,结果发现：（1）无论语义相关词对比率高还是低,均存在语义启动效应和刺激质量效应,且汉字刺激质量与语义启动之间均存在交互作用;（2）轻度模糊刺激较重度模糊刺激受到的语义启动效应更大。结果表明,即使排除了额外反馈的作用,汉字刺激质量与语义启动之间仍存在交互作用,进一步支持交互激活模型。     

Using models to correct data: paleodiversity and the fossil record

Despite an enormous philosophical literature on models in science, surprisingly little has been written about data models and how they are constructed. In this paper, I examine the case of how paleodiversity data models are constructed from the fossil data. In particular, I show how paleontologists are using various model-based techniques to correct the data. Drawing on this research, I argue for the following related theses: first, the ‘purity’ of a data model is not a measure of its epistemic reliability. Instead it is the fidelity of the data that matters. Second, the fidelity of a data model in capturing the signal of interest is a matter of degree. Third, the fidelity of a data model can be improved ‘vicariously’, such as through the use of post hoc model-based correction techniques. And, fourth, data models, like theoretical models, should be assessed as adequate (or inadequate) for particular purposes.

     

Distress Tolerance and Social Support in Adolescence: Predicting Risk for Internalizing and Externalizing Symptoms Following a Natural Disaster

The purpose of the multi-measure, multi-wave, longitudinal study was to examine the interactive relation between behavioral distress tolerance (DT) and perceived social support (PSS) in 352 tornado-exposed adolescents aged 12–17 years (M = 14.44; SD = 1.74). At baseline, adolescents completed a computer-based task for DT, and self-report measures of PSS, depressed mood, posttraumatic stress disorder (PTSD), substance use, and interpersonal conflict. Symptoms also were assessed 4 and 12 months after baseline. Findings showed that lower levels of DT together with lower levels of PSS conferred risk for elevated symptoms of prospective depression (t(262) = ?2.04, p = .04; r_{effect size} = 0.13) and PTSD (t(195) = ?2.08, p = .04; r_{effect size} = 0.15) following a tornado. However, only PSS was significant in substance use t(139) = 2.20, p = .03; r_{effect size=}0.18) and conflict (t(138) = ?4.05, p < .0001; r_{effect size=}0.33) in our sample. Implications regarding adolescent DT, the transdiagnostic nature of PSS, and the clinical applications of our findings in the aftermath of a natural disaster are discussed.     

Research on social class and intolerance in the context of American history and ideology

This article examines the trends reported in empirical investigations of the relationship between social class and intolerance over the last three decades in the light of American history and ideology. Two key studies are cited as landmark works: The Authoritarian Personality and Communism, Conformity, and Civil Liberties. The author notes that findings from both works, as well as conclusions drawn from related studies, have been interpreted as supporting an essentially negative view of the lower classes with regard to tolerance of nonconformity. A brief critique of research findings is presented.
