Intolerance of uncertainty and difficulties in emotion regulation: Proposal for an integrative model of generalized anxiety disorder

Introduction

The Intolerance of Uncertainty Model (IUM) is a well-tested model of generalized anxiety disorder (GAD).

Logical Metonymy Resolution in a Words‐as‐Cues Framework: Evidence From Self‐Paced Reading and Probe Recognition

Logical metonymy resolution (begin a book → begin writing a book) has traditionally been explained either through complex lexical entries (qualia structures) or through the integration of the implicit event via post‐lexical access to world knowledge. We propose that recent work within the words‐as‐cues paradigm can provide a more dynamic model of logical metonymy, accounting for early and dynamic integration of complex event information depending on previous contextual cues (agent and patient). We first present a self‐paced reading experiment on German subordinate sentences, where metonymic sentences and their paraphrased version differ only in the presence or absence of the clause‐final target verb (Der Konditor begann die Glasur → Der Konditor begann, die Glasur spreading the icing). Longer reading times at the target verb position in a high‐typicality condition (baker + icing → spread ) suggest that we make use of knowledge activated by lexical cues to build expectations about events. The early and dynamic integration of event knowledge in metonymy interpretation is bolstered by further evidence from a second experiment using the probe recognition paradigm. Presenting covert events as probes following a high‐typicality or a low‐typicality metonymic sentence (Der Konditor begann die Glasur → SPREAD ), we obtain an analogous effect of typicality at 100 ms interstimulus interval.     

Categorization behaviour in adults,adolescents, and attention-deficit/hyperactivity disorder adolescents: A comparative investigation

Although significant progress has been made with respect to our understanding of categorization and concept learning behaviour in adults, much less is known about how this key capacity plays out with respect to more restrictive populations. This is unfortunate because much may be revealed about the nature of concept learning by examining the limits exhibited by special populations. With this tenet in mind, in what follows, we investigated key aspects of concept learning in terms of the unexplored comparative performance of three populations—adults, adolescents, and adolescents with attention-deficit/hyperactivity disorder (ADHD). To do so, we employed a novel parainformative experimental task involving categorical stimuli with four objects defined over three dimensions. The learning difficulty ordering for these types of three-dimensional stimuli has proven robust and has been replicated by several researchers. Indeed, in our experiment, we observed the same concept learning ordering in adults and adolescents, but not in ADHD adolescents: For example, the latter group showed greatly impaired categorization performance on stimuli characterized by an “exclusive-or” rule. However, categorization performance on such type of stimuli indicated good reliability in discriminating between adolescents with and without ADHD (receiver-operating characteristic, ROC?=?.82). We accurately predicted and accounted for these results using generalized invariance structure theory (GIST; Vigo, 2013. The GIST of concepts. Cognition, 129, 138–162), which posits that organisms detect invariance patterns in stimuli that are necessary precursors to concept formation.     

Patterns of situational appraisal in experiences of worry and anxiety

Abstract

Three studies investigating differences in people's appraisals of worry and anxiety situations are presented. First, data from a study by Reisenzein & Spielhofer (1994) were reanalyzed. Second, two further studies were conducted to replicate the findings of the reanalysis and to explore whether any additional appraisal dimensions were relevant for a differentiation of worry and anxiety situations. In sum, results showed that appraisals associated with situations in which worry and anxiety were experienced differed on eight appraisal dimensions. Compared to experiences of anxiety, experiences of worry were more often associated with positive self-evaluation, positive social-relationship evaluation, feelings of closeness, and sentiments of importance, and less often associated with feelings of inferiority. Moreover, in worry experiences, focus was often not on the self, but on other persons. Finally, with respect to temporal dimensions, worry situations were less often associated with notions of suddenness and momentariness than anxiety situations. Implications of these findings are discussed with respect to models of emotional appraisal and research on worry and generalized anxiety disorder.     

Representation of interlaced trilattices

Trilattices are algebraic structures introduced ten years ago into logic with the aim to provide a uniform framework for the notions of constructive truth and constructive falsity. In more recent years, trilattices have been used to introduce a number of many-valued systems that generalize the Belnap–Dunn logic of first-degree entailment, proposed as logics of how several computers connected together in a network should think in order to deal with incomplete and possibly contradictory information. The aim of the present work is to develop a first purely algebraic study of trilattices, focusing in particular on the problem of representing certain subclasses of trilattices as special products of bilattices. This approach allows to extend the known representation results for interlaced bilattices to the setting of trilattices and to reduce many algebraic problems concerning these new structures to the better-known framework of lattice theory.     

Acute exercise effects on worry,state anxiety,and feelings of energy and fatigue among young women with probable Generalized Anxiety Disorder: A pilot study

BackgroundLittle is known about the acute effects of exercise among individuals with clinical or subclinical Generalized Anxiety Disorder (GAD).PurposeThus, this study examined worry, state anxiety, and feelings of energy and fatigue responses to acute aerobic exercise and quiet rest, and explored potential moderators of response among young adult women with worry scores indicative of GAD.MethodsSeventeen young women with Penn State Worry Questionnaire scores ≥45 (60 ± 8) completed 30-min treadmill running at 65%–85% heart rate reserve (%HRR) and 30-min seated quiet rest in counterbalanced order. Outcomes included worry, state anxiety, and feelings of energy and fatigue. Two condition X two time repeated measures ANOVA examined differences across condition and time. Hedges’ d effect sizes (95%CI) were calculated to quantify and compare the magnitude of change. Independent-samples t-tests explored potential moderators of outcome response.ResultsTotal exercise time was 35.8 ± 3.4min with a mean 30.3 ± 0.16 in-zone minutes (65%-85%HRR); participants exercised at ∼72.9 ± 0.03 %HRR (range 66%–79%). Compared with quiet rest, acute exercise significantly improved worry engagement, state anxiety, and feelings of energy and fatigue (all p ≤ 0.031). Moderate-to-large (d = 0.44 to 1.69) reductions in state anxiety and feelings of fatigue and improvements in feelings of energy were found. Exercise-induced reductions in worry engagement were significantly larger among non-high trait anxious participants. Compared to normal sleepers, quiet rest significantly increased feelings of fatigue among poor sleepers.ConclusionFindings provide support for the positive effects of acute aerobic exercise on worry, state anxiety, and feelings of energy and fatigue among young women with worry indicative of GAD.     

Generalized graded unfolding model with structural equation for subject parameters

The generalized graded unfolding model (GGUM) is capable of analyzing polytomous scored, unfolding data such as agree‐disagree responses to attitude statements. In the present study, we proposed a GGUM with structural equation for subject parameters, which enabled us to evaluate the relation between subject parameters and covariates and/or latent variables simultaneously, in order to avoid the influence of attenuation. Additionally, an algorithm for parameter estimation is newly implemented via the Markov Chain Monte Carlo (MCMC) method, based on Bayesian statistics. In the simulation, we compared the accuracy of estimates of regression coefficients between the proposed model and a conventional method using a GGUM (where regression coefficients are estimated using estimates of θ). As a result, the proposed model performed much better than the conventional method in terms of bias and root mean squared errors of estimates of regression coefficients. The study concluded by verifying the efficacy of the proposed model, using an actual data example of attitude measurement.     

犯罪心理学研究中运用量化方法引起的理论思考

量化与统计分析,是一项重要的研究方法。这一方法在犯罪心理学研究中得到了广泛运用,同时也存在着使用的局限性。犯罪人有很强的心理掩饰性,对包括犯罪人在内的人的心理的测量实际上是一种间接测量,测得的数据是心理学家标定的数据,兼有客观性与主观性。量化研究如果不与科学思维相结合,有可能得出浅薄平庸甚至错误的结论。心理学研究应当以"人性"为基点,多种方法综合运用,实现量化方法与非量化方法的有机结合。     

Truth and Generalized Quantification*

Kripke [1975] gives a formal theory of truth based on Kleene's strong evaluation scheme. It is probably the most important and influential that has yet been given—at least since Tarski. However, it has been argued that this theory has a problem with generalized quantifiers such as All(?, ψ)—that is, All ?s are ψ—or Most(?, ψ). Specifically, it has been argued that such quantifiers preclude the existence of just the sort of language that Kripke aims to deliver—one that contains its own truth predicate. In this paper I solve the problem by showing how Kleene's strong scheme, and Kripke's theory based on it, can in a natural way be extended to accommodate the full range of generalized quantifiers.
