Perceptual rigidity and closure as functions of anxiety.

Ss chosen from an introductory class in psychology were given the Grice Revision of the Taylor Scale of Manifest Anxiety. High and low scorers were evenly divided as to sex and assigned to threatening or non-threatening instruction groups. Perceptual tasks were then administered. The results indicated that threat induced anxiety modified perceptual processes significantly in the case of tachistoscopic closure, rigidity, and stability. These three functions involve maintaining constancy of a previously established percept in the face of incompatible cues from the environment. Manifest anxiety was related only to the stability test.

Goal-relevant dimensions of hypochondriacal tendencies and their relation to symptom manifestation and psychological distress.

A national sample of 60 male and 61 female adults completed a telephone interview that included measures of hypochondriacal tendencies, psychological distress, and symptom manifestation. They also provided cognitive evaluations for their most important health goal on scales measuring self-efficacy, value, planning, self-reward, self-criticism, self-monitoring, social comparison, and positive and negative goal-based arousal. Health goal cognition significantly predicted hypochondriacal tendencies measured 15 to 30 days after the goal assessment, even after controlling for chronic illness diagnosis. Correlations between goal cognition and hypochondriacal tendencies differed from those observed for psychological distress, and no significant correlations emerged with symptom manifestation. Results support a motivational account of hypochondriacal tendencies and extend previous goals research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attentional biases for threatening faces in children: Vigilant and avoidant processes.

The authors examined the processing of threat-related information in childhood anxiety with the emotional Stroop task and the dot probe task. In study 1, a nonclinical sample of 112 pupils (mean age = 9 years) performed pictorial versions of both tasks. For each task, an index indicating a bias for threat processing was computed. Positive correlations were found between these indices and anxiety. When compared with the original emotional Stroop index, the absolute value of the emotional Stroop index was a better predictor of anxiety. It was possible to replicate this result in study 2 with 80 pupils (mean age = 8.6 years). Results are discussed with regard to vigilance and avoidance as basic mechanisms underlying performance on the tasks. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perceptual preferences as a function of personality variables under normal and stressful conditions.

"This investigation… studied the relationship between preference for detail and depth, which are assumed to underlie 'texture' responses [on the Rorschach], and measures of dependency, insecurity, and anxiety under normal and stressful conditions… . The more an individual acknowledges his dependency on others, the greater is his preference for detail… . Under conditions of induced stress, the change in preference for detail is a function of the level of the individual's insecurity… . Under conditions of induced stress, the change in preference for depth is a function of the level of the individual's symptomatic anxiety."

Perceptual reactions to threat under varying conditions of measurement.

This study investigated the perceptual recognition behavior for threat and nonthreat words under 3 conditions of measurement, stimulus absent, stimulus present, and forced choice. The results indicated that the probability of using threat words as recognition guesses in the stimulus-absent condition is predictive of (a) probability of usage in stimulus present and (b) differential accuracy for threat and nonthreat words in stimulus present. However, stimulus-absent data failed to predict forced-choice accuracy for threat. Further, stimulus present accuracy data failed totally to predict forced-choice accuracy data. The pattern of results emphasizes the vital contribution of response factors in producing the perceptual defense effect. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perceptual recognition as a function of anxiety, motivation, and the testing situation.

The hypothesis was made that degree of anxiety and motivation would influence S's performance on tasks measuring skill in discovering objects embedded in a stimulus field, particularly as the situation was structured to be stressful or not. Ss low in anxiety and high in motivation performed significantly better than Ss high in anxiety but with low motivation. In the nonstressful situation, Ss low in anxiety and motivation performed significantly poorer than their counterparts. It is recommended, therefore, that situational task variables be considered as crucial factors in analysing behavior. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perceptual bias for affective and nonaffective information in asymmetric Parkinson's disease.

Objective: To relate lateralized impairments of visual perception in Parkinson's disease to asymmetries in the severity of motor symptoms. Method: Ten patients with worse left-sided motor symptoms (LPD), 15 with worse right-sided (RPD), and 13 healthy age-matched controls (all right-handed) viewed mirror-imaged pairs of emotional chimeric faces, (left side smiling, right neutral, and vice versa), of greyscales (strips whose luminance varied smoothly from black on the left to white on the right, and vice versa) and of gender chimeric faces (left side male, right female, and vice versa). Participants signaled which stimulus appeared happier, brighter, or more feminine, respectively, so showing which side received more attention. Results: For emotional chimeras, controls and LPD showed little bias, whereas RPD showed a strong bias to left hemispace (p = .018, r = .45). Across all patients, this bias was associated with severity of right-sided motor impairment (p = .018, r = .49). The bias was much weaker and insignificant for greyscales (p = .72, r = .14). For gender chimeras, RPD again showed a significantly greater left hemispace bias than did LPD (p = .037, r = .47), although neither patient group differed significantly from controls. Across all patients, this bias correlated with ratio of right-to-left symptom severity (p = .044, r = .48). Conclusions: The left hemispace bias in RPD is greater for facial than for luminance judgments, and is amplified for emotional judgments. Asymmetrical degeneration of the striatum, particularly involving the left side, appears to underlie this deficit in visual processing.

Effects of smoking opportunity on attentional bias in smokers.

The emotional Stroop task was used to examine the influence of opportunity to smoke on attentionall bias to smoking-related stimuli. At the outset of the study, 92 nicotine-deprived smokers were told that they (a) would, (b) would not, or (c) might be able to smoke during the experiment. Next, participants completed an emotional Stroop task, in which they were presented with smoking-related or -unrelated words in an unblocked format. Smokers demonstrated interference to the smoking words, relative to matched neutral words, F(1, 87)?=?18.0, p?F(2, 87)?=?4.35, p?     

Observational fear conditioning in the acquisition and extinction of attentional bias for threat: An experimental evaluation.

Anxious persons show automatic and strategic attentional biases for threatening information. Yet, the mechanisms and processes that underlie such biases remain unclear. The central aim of the present study was to elucidate the relation between observational threat learning and the acquisition and extinction of biased threat processing by integrating emotional Stroop color naming tasks within an observational differential fear conditioning procedure. Forty-three healthy female participants underwent several consecutive observational fear conditioning phases. During acquisition, participants watched a confederate displaying mock panic attacks (UCS) paired with a verbal stimulus (CS+), but not with a second nonreinforced verbal stimulus (CS-). As expected, participants showed greater magnitude electrodermal and verbal-evaluative (e.g., distress, fear) conditioned responses to the CS+ over the CS- word. Participants also demonstrated slower color-naming latencies to CS+ compared to the CS- word following acquisition and showed attenuation of this preferential processing bias for threat following extinction. Findings are discussed broadly in the context of the interplay between fear learning and processing biases for threat as observed in persons suffering from anxiety disorders.

Attentional Bias and Drinking to Cope With Social Anxiety.

This study investigated the sensitivity of the emotional Stroop test for identifying individuals who reported drinking to cope with social fears. Community volunteers completed a modified Stroop task during which social threat, alcohol-related, and control words were presented. High scores on drinking-to-cope measures were hypothesized to be associated with longer response latencies to both social threat and alcohol-related words. Consistent with previous studies, alcohol dependence was correlated with latencies for alcohol-related words, and level of social anxiety was correlated with response latency to social threat words. As expected, drinking-to-cope measures predicted response latency to alcohol-related and social threat words. These results suggest that the emotional Stroop test is useful in studying the relationship between social anxiety and alcohol consumption.

The hidden consequences of racial salience in videotaped interrogations and confessions.

Evaluations of videotaped criminal confessions can be influenced by the camera perspective taken during recording. Interrogations and confessions recorded with the camera directing observers' visual attention onto the suspect lead to biased judgments of the suspect. Although a camera perspective that directs visual attention onto the suspect and interrogator equally appears to promote unbiased judgments, investigations to date have relied on videotapes that depict only Caucasian suspects and interrogators. We examined the possibility that even equal-focus videotapes may become problematic when the suspect is a minority (e.g., Chinese American or African American) and the interrogator is Caucasian. That is, to the extent that Caucasian observers are inclined to direct more of their attention onto minorities, an effect documented previously, we expected biased judgments of the suspect to also occur in equal-focus videotapes. Three experiments provided evidence of this racial salience bias. Implications are discussed, including a practical way of avoiding the bias.

"What matters in implicit task sequence learning: Perceptual stimulus features, task sets, or correlated streams of information?" Correction to Weiermann et al. (2010).

Reports an error in "What matters in implicit task sequence learning: Perceptual stimulus features, task sets, or correlated streams of information" by Brigitte Weiermann, Josephine Cock and Beat Meier (Journal of Experimental Psychology: Learning, Memory, and Cognition, 2010[Nov], Vol 36[6], 1492-1509). Two figures appearing on pages 1500 and 1502 contained incorrect labels for the x-axis of the control condition (ranran). The correct versions of Figure 3 and Figure 4 are provided in the erratum. (The following abstract of the original article appeared in record 2010-22281-001.) Implicit task sequence learning may be attributed to learning the order of perceptual stimulus features associated with the task sequence, learning a series of automatic task set activations, or learning an integrated sequence that derives from 2 correlated streams of information. In the present study, our purpose was to distinguish among these 3 possibilities. In 4 separate experiments, we replicated and extended a previous study by Heuer, Schmidtke, and Kleinsorge (2001). The presence or absence of a sequence of tasks, as well as that of a sequence of different task-to-response mappings, was manipulated independently within experiments. Evidence of implicit sequence learning was found only when correlated sequences of tasks and mappings were present. No sequence learning effects were found when only a single task sequence or a single mapping sequence was present, even when the structure of the single sequence was identical to the structure of the integrated sequence of task-mapping combinations. These results suggest that implicit task sequence learning is not dependent on either perceptual learning of stimulus features or automatic task-set activation per se. Rather, it appears to be driven by correlated streams of information. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Emotional attention set-shifting and its relationship to anxiety and emotion regulation.

Attentional deployment is a primary strategy individuals use to regulate emotion. In 2 experiments, a measure of an individual’s ability to deploy attention toward and away from emotional mental representations was developed. This measure of attentional control capacity for emotion adapted an explicit-cuing task switching paradigm in which participants had to shift between emotional and neutral mental sets. Experiment 1 (N = 118) showed that those higher in trait anxiety and worrisome thoughts took longer to switch from a neutral to an emotional mental set. In Experiment 2 (N = 42), participants were given a stressful anagram task, and those who switched more efficiently from a neutral set to an emotional set were more frustrated by the stressful task. In addition, those who switched more efficiently from an emotional set to a neutral set persisted longer on the stressful task. These findings provide an initial step toward identifying possible mechanisms through which individuals apply attentional control to emotional mental representations to regulate emotion.

Perceptual and cognitive load interact to control the spatial focus of attention.

Caparos and Linnell (2009, 2010) used a variable-separation flanker paradigm to show that (a) when cognitive load is low, increasing perceptual load causes spatial attention to focus and (b) when perceptual load is high, decreasing cognitive load causes spatial attention to focus. Here, we tested whether the effects of perceptual and cognitive load on spatial focus remain when, respectively, cognitive load is high and perceptual load is low. We found that decreasing cognitive load only causes spatial attention to focus when perceptual load is high and the stimulus encourages this. Moreover, and contrary to the widely held assumption that perceptual load focuses attention automatically (Lavie, Hirst, de Fockert, & Viding, 2004), perceptual load exerts its focusing effect only with the engagement of cognitive resources when cognitive load is low. In sum, perceptual and cognitive mechanisms exert interacting effects and operate in concert to focus spatial attention. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Perceptual reactivity to threat and neutral words under varying experimental conditions.

30 male and 30 female introductory psychology student volunteers were randomly assigned by sex to one of 3 experimental groups and were tested for perceptual reactivity to threat and neutral words matched for word frequency. The experimental groups differed only in terms of induced strength of expectation for threat words from 0% to 100%. Findings support the prediction that the discrepancy between threat and neutral word thresholds decreases as strength of set for threat stimuli increases. However threat words were found to have higher report thresholds than neutral words in all conditions. 18 references. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of Motivational Cues on Perceptual Asymmetry: Implications for Creativity and Analytical Problem Solving.

In 4 experiments, participants were led to focus on either the prospect of positive outcomes (approach anticipation) or the prospect of negative outcomes (avoidance anticipation) and were subsequently administered behavioral measures of relative hemispheric activation. It was found that approach, relative to avoidance-related anticipatory states, produced greater relative right (diminished relative left) hemispheric activation. Experiment 3 additionally demonstrated that this pattern of activation was reversed when approach and avoidance states were not merely anticipatory but were also emotionally arousing. Finally, Experiment 4 replicated earlier findings demonstrating an influence of approach and avoidance anticipatory states on creativity and analytical problem solving (R. S. Friedman & J. F?rster, 2001, 2003) and provided evidence that such effects are mediated by differences in relative hemispheric activation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Depression moderates smoking behavior in response to a sad mood induction.

Stress and anxiety have been shown to increase smoking motivation. There is limited experimental data on depressed or sad mood and smoking. This study investigated the effects of two induced moods on smoking behavior. Depression scores were examined as a potential moderator and mood changes were tested as a potential mediator. Smokers (N = 121) were randomly assigned to receive either a sad induction or a neutral induction via standardized film clips. Among participants with higher depression scores, smoking duration and the number of cigarette puffs were greater in response to the sad condition. There was also a marginal interactive effect on the change in expired air carbon monoxide among this subsample; however, no differences in smoking latency or craving were observed. Changes in positive mood partially mediated the effect of condition on smoking behavior among participants with high depression scores. There was no modifying effect of gender or mediating effect of negative mood changes. The results provide preliminary support that decreases in positive mood may have a greater influence on smoking behavior among depression-prone smokers than less psychiatrically vulnerable smokers.

Perceptual categorizations of love and anger cues in schizophrenics.

The 1st study identified 4 filmed scenes indicative of high love, high anger, medium love, and medium anger. The 2nd study compared 30 good premorbid schizophrenics and 30 normals on the high love and high anger scenes. They were not differentiated on the high love scene. On the high anger scene, the normals reported significantly more anger than the good premorbids. The 3rd study evaluated 48 poor premorbid schizophrenics, 48 good premorbid schizophrenics, and 48 normals on 4 scenes of high love, high anger, medium love, and medium anger. The good premorbids and the normals were not different on the high love scene, but significantly different from the poor premorbids. On the high anger scene, good and poor premorbids were significantly different from normals. (18 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The consequences of depressive affect on functioning in relation to Cluster B personality disorder features.

The authors examined the effects of depressed affect (DA) on functioning measured by behavioral tasks pertaining to abstract reasoning, social functioning, and delay of gratification in relation to Cluster B personality disorder features (PDs) in a clinical sample. Individuals were randomly assigned to either a DA induction or control condition. Consistent with clinical conceptualizations, the authors expected that Cluster B PD symptoms would be related to maladaptive responding (e.g., poorer delay of gratification) when experiencing DA. As hypothesized, many of the relations between the Cluster B PDs and functioning were moderated by DA (e.g., borderline PD was negatively related to abstract reasoning, but only in the DA condition). However, many of the Cluster B PDs symptom counts were related to more adaptive responses in the DA condition (e.g., less aggressive social functioning, better delay of gratification). The authors speculate that individuals with Cluster B PDs may be more likely to respond maladaptively to alternative negative mood states, such as anger and fear.

The Easy to Hard Effect and Perceptual Learning in Flavor Aversion Conditioning.

In experiments on the easy to hard effect, pretraining on an easy discrimination results in better performance on a harder version of the discrimination than pretraining on the hard discrimination itself. In addition, some theories posit that unreinforccd preexposure to the easy discrimination should be as effective as differentially reinforced easy pretraining in producing the easy to hard effect. Two experiments on flavor aversion conditioning in rats demonstrated the basic easy to hard effect. However, in neither experiment was easy preexposure more effective than hard preexposure in enhancing learning of the hard discrimination. Indeed, in Experiment 2, rats preexposed to an easy discrimination learned the hard discrimination significantly more slowly than those preexposed to the hard discrimination itself.
