Biased cognitive operations in anxiety: artefact, processing priorities or attentional search?

It has been shown that, under certain circumstances, anxiety is associated with a processing bias favouring threatening information. To explain why this bias is apparent only on certain cognitive tasks, it has recently been proposed that the bias operates only when there is competition for processing resources. The present study sought to replicate previous evidence for the 'competition' hypothesis, while taking into account a potential confounding factor of word categorization in the stimulus materials. Anxious patients and normal controls were compared on their lexical decision times for threatening, categorized neutral and uncategorized neutral words that were presented either alone or accompanied by irrelevant nonword stimuli (i.e. absence vs presence of competition). The results were only partially consistent with previous findings and highlighted the importance of considering separately the effects of word valence and word categorization. When the latter was taken into account, the results indicated that an anxiety-related bias was only evident when there was competition for processing resources and when the information was presented outside the focus of Ss' attention. A modified version of the competition hypothesis was proposed in the light of these results and previous research into attentional biases in anxiety.     

Bias in interpretation of ambiguous sentences related to threat in anxiety

In the 1st of 2 experiments, currently clinically anxious, recovered clinically anxious, and normal control subjects were presented with a mixture of unambiguous and ambiguous sentences; both threatening and nonthreatening interpretations were possible for the latter. A subsequent recognition-memory test indicated that the currently anxious subjects were more likely than normal control and recovered anxious subjects to interpret the ambiguous sentences in a threatening fashion rather than in a nonthreatening fashion. This suggests that the biased interpretation of ambiguity found in currently anxious subjects reflected their anxious mood state. A 2nd experiment established that the difference in interpretative processes between currently anxious and control subjects was not due to response bias and that the interpretative bias was a reasonably general one.     

A system for computer control of auditory stimuli

A computer system for generation of auditory stimuli is described. The system produces natural-speech or software-generated stimuli for monaural, binaural, or dichotic presentation. Stimuli have been generated for experiments run both on-line and off-line.     

Communication accuracy in lower and middle-SES children as a function of task abstraction

The communication encoding performance of lower-SES black, lower-SES white, and middle-SES white children was evaluated when the same familiar stimuli for eliciting communication were presented at three different levels of abstraction. No differences were found between social-class groups. Performance did not differ as a function of level of abstraction. The social group x level of abstraction interaction was not significant. Thus the level of abstraction of the stimuli does not impede the communication encoding performance of lower-SES children. Previous findings of social-class differences in communication accuracy may be an artifact of stimuli that are not equally familiar to all groups.     

Emotional Competence and Anxiety in Childhood and Adolescence: A Meta-Analytic Review

Anxiety is conceptualized as a state of negative emotional arousal that is accompanied by concern about future threat. The purpose of this meta-analytic review was to evaluate the evidence of associations between emotional competence and anxiety by examining how specific emotional competence domains (emotion recognition, emotion expression, emotion awareness, emotion understanding, acceptance of emotion, emotional self-efficacy, sympathetic/empathic responses to others’ emotions, recognition of how emotion communication and self-presentation affect relationships, and emotion regulatory processes) relate to anxiety in childhood and adolescence. A total of 185 studies were included in a series of meta-analyses (N’s ranged from 573 to 25,711). Results showed that anxious youth are less effective at expressing (r = ?0.15) and understanding emotions (r = ?0.20), less aware of (r = ?0.28) and less accepting of their own emotions (r = ?0.49), and report less emotional self-efficacy (r = ?0.36). More anxious children use more support-seeking coping strategies (r = 0.07) and are more likely to use less adaptive coping strategies including avoidant coping (r = 0.18), externalizing (r = 0.18), and maladaptive cognitive coping (r = 0.34). Emotion acceptance and awareness, emotional self-efficacy, and maladaptive cognitive coping yielded the largest effect sizes. Some effects varied with children’s age. The findings inform intervention and treatment programs of anxiety in youth and identify several areas for future research.     

Developing rich and quickly accessed knowledge of an artificial grammar

In contrast to prior research, our results demonstrate that it is possible to acquire rich, highly accurate, and quickly accessed knowledge of an artificial grammar. Across two experiments, we trained participants by using a string-edit task and highlighting relatively low-level (letters), medium-level (chunks), or high-level (structural; i.e., grammar diagram) information to increase the efficiency of grammar acquisition. In both experiments, participants who had structural information available during training generated more highly accurate strings during a cued generation test than did those in other conditions, with equivalent speed. Experiment 2 revealed that structural information enhanced acquisition only when relevant features were highlighted during the task using animation. We suggest that two critical components for producing enhanced performance from provided model-based knowledge involve (1) using the model to acquire experience-based knowledge, rather than using a representation of the model to generate responses, and (2) receiving that knowledge precisely when it is needed during training.     

Who Cares About Human Rights?

Previous studies of human rights attitudes are reviewed, new measures are reported, and a three-factor model is identified (Human Rights Endorsement, Commitment, and Restriction). Individual differences that predict attitudes on each factor overlapped but differed. Dispositional empathy, education, and global knowledge contributed to an endorsement of human rights ideals, but none of these affected commitment or restriction. Globalism (vs. nationalism) and principled moral reasoning strengthened human rights commitment, while ethnocentrism and the social dominance orientation weakened it. Authoritarianism, ethnocentrism, and belief that the world cannot be changed increased a willingness to restrict the rights of unpopular groups, while principled moral reasoning and self-rated liberalism decreased it. In short, the individual differences that influence human rights attitudes depend substantially upon which dimension of these attitudes is considered.
