Selective orienting of attention to masked threat faces in social anxiety

The aims of the study were two-fold: to examine whether previous evidence of a pre-attentive bias for masked threat faces in anxious individuals could be replicated, and to assess the relationship between the predicted bias and measures of trait and social anxiety. Pairs of face stimuli were briefly displayed and masked in a modified version of the visual probe task. Results indicated that high anxious individuals were faster to respond to probes occurring in the spatial location of masked threat rather than neutral faces; consistent with their attention being automatically captured by sub-threshold threat cues. Furthermore, this vigilance effect for masked threat faces appeared to be primarily a function of social anxiety and social avoidance, rather than trait anxiety. It was also more apparent when threat faces were presented in the left visual field, suggestive of right hemisphere involvement.     

Physical abuse amplifies attention to threat and increases anxiety in children

Two experiments using event-related potentials (ERPs) examined the extent to which early traumatic experiences affect children's ability to regulate voluntary and involuntary attention to threat. The authors presented physically abused and nonabused comparison children with conflicting auditory and visual emotion cues, posed by children's mothers or a stranger, to examine the effect of emotion, modality, and poser familiarity on attention regulation. Relative to controls, abused children overattended to task-relevant visual and auditory anger cues. They also attended more to task-irrelevant auditory anger cues. Furthermore, the degree of attention allocated to threat statistically mediated the relationship between physical abuse and child-reported anxiety. These findings indicate that extreme emotional experiences may promote vulnerability for anxiety by influencing the development of attention regulation abilities.     

Depression and attention to two kinds of meaning: A cognitive perspective

The complexity of a mental disorder such as depression is such that a way of interlinking the neural, mental and interpersonal levels is needed. This paper proposes that a theoretical framework which distinguishes, and relates, macro-theory and micro-theory at these levels can serve this purpose. The 'Interacting Cognitive Subsystems' approach to mental architecture is used to show how, via the detailed specification of mental processes and representations, a macro-theory of mental architecture contributes to our understanding of depressed states. In the account advanced by Teasdale and Barnard depressed states are seen as being maintained by an abnormal version of a dynamic dialogue between two qualitatively distinct types of meaning: one is referentially specific, propositional meaning, the other consists of holistic schemata rich in latent content and is called implicational meaning. In depressed states with ruminative and avoidant thought patterns, the mental function of attention is seen as being directed preferentially at propositional meanings. There is a corresponding neglect of attention to implicational meanings. The paper concludes with a brief discussion of how this approach can address transdiagnostic issues and how it may suggest new strategies for therapeutic interventions.     

The multidimensionality of test anxiety: A test of different models

Abstract

Confirmatory factor analysis was employed to test the multidimensional structure of test anxiety. Starting with the traditional two-factor model, it was of interest whether additional dimensions could still be represented by a single higher-order factor of test anxiety or whether the additional dimensions represented correlates of test anxiety. The Revised Test Anxiety (RTA) scale and the German Test Anxiety Inventory (TAI-G) were combined collecting data from a binational sample of 218 American and 218 German university students. Considering the statistical and theoretical aspects of model fit, they indicated that a model consisting of three primary factors (worry, emotionality, and lack of confidence) fit the data best. While distraction and self-efficacy may be regarded as correlates of test anxiety, lack of confidence was substantiated as a component of test anxiety. Implications for the conceptualization of the content domain and hence area of test anxiety were discussed.     

Selective processing of threat cues in anxiety states: a replication

A replication of Mathews and MacLeod's (Behav. Res. Ther. 23, 563-569, 1985) study, using a modified Stroop task, confirmed that threat words selectively interfere with the colour-naming performance of generally anxious patients, compared with normal controls. Clearer evidence was obtained of a highly specific interference effect of threat words that were congruent with the predominant worries reported by anxious patients. However, there was no evidence of a subsequent recognition memory bias for the threat words in anxious Ss. These results are discussed in relation to findings from other recent experiments investigating attentional and memory biases for threat-related information in anxiety states, and their implications for cognitive theories of anxiety are considered.     

Selective attention and threat: quick orienting versus slow disengagement and two versions of the dot probe task

The dot probe task is often used to assess attentional bias in anxiety, but some aspects need clarification. First, the results, which are traditionally summarized in an attentional bias index, do not allow for distinguishing between different selective attention processes; orienting and disengagement. Second, different versions of the dot probe task have been used with unknown relative merits. Participants (N=133) completed two versions of the dot probe task: the detection task (i.e. is there a probe?) and the differentiation task (i.e. what sort of probe is it?). The analysis carried out allowed for a differentiation between orienting and disengagement. The main finding was that trait anxiety is related to disengagement difficulties and not to speed of orienting. Concerning the relative merits of the two dot probe task versions, the results suggest that the detection task may be superior to the differentiation task. Implications for past and future research are discussed.     

Selective attention for masked and unmasked emotionally toned stimuli: Effects of trait anxiety,state anxiety,and test order

We investigated selective attention for masked and unmasked, threat, and positively valenced words, in high trait anxious (HTA) and low trait anxious (LTA) individuals using the emotional Stroop colour‐naming task. State anxiety was varied within participants through the threat of electric shock. To investigate whether the sequencing of the state anxiety manipulation affected colour‐naming latencies, the ordering of the shock threat and shock safe conditions was counterbalanced across participants. The results indicated that the ordering of the state anxiety manipulation moderated masked and unmasked threat bias effects. Specifically, relative to LTA individuals, HTA individuals showed a threat interference effect, but this effect was limited to those who performed under the threat of shock in the later stages of the experiment. Irrespective of exposure mode and state anxiety status, all individuals showed interference for threat in the early stages of the experiment, relative to a threat facilitation effect in the later stages of the experiment. For the unmasked trials alone, the data also revealed a significant threat interference effect for the HTA group relative to the LTA group in the shock threat condition, and this effect was evident irrespective of shock threat order. The results are discussed with respect to the automatic nature of emotional processing in anxiety.     

Selective attention to threat in the dot probe paradigm: differentiating vigilance and difficulty to disengage

The dot probe task [J Abnorm Psychol 95 (1986) 15] is an often-used paradigm to investigate selective attention to threat. A facilitated response to probes that appear at the same location of threat information in comparison with responses to probes at the opposite location of threat information is interpreted as vigilance for threat. We argue that the findings in the dot probe paradigm are ambiguous evidence for the vigilance to threat hypothesis. Results can also be interpreted as a difficulty to disengage from threat. In this study, 44 undergraduates performed a pictorial version of the probe detection task. Taking into account the reaction times on neutral trials, we found no evidence for a facilitated detection of threatening information. It was found that the dot probe effects are at least partially due to disengagement effects. The implications of these results for the understanding of attentional bias in normal and anxious individuals are discussed.     

Selective attention to emotional prosody in social anxiety: a dichotic listening study

The majority of evidence on social anxiety (SA)-linked attentional biases to threat comes from research using facial expressions. Emotions are, however, communicated through other channels, such as voice. Despite its importance in the interpretation of social cues, emotional prosody processing in SA has been barely explored. This study investigated whether SA is associated with enhanced processing of task-irrelevant angry prosody. Fifty-three participants with high and low SA performed a dichotic listening task in which pairs of male/female voices were presented, one to each ear, with either the same or different prosody (neutral or angry). Participants were instructed to focus on either the left or right ear and to identify the speaker’s gender in the attended side. Our main results show that, once attended, task-irrelevant angry prosody elicits greater interference than does neutral prosody. Surprisingly, high socially anxious participants were less prone to distraction from attended-angry (compared to attended-neutral) prosody than were low socially anxious individuals. These findings emphasise the importance of examining SA-related biases across modalities.     

Written threat: Electrophysiological evidence for an attention bias to affective words in social anxiety disorder

Social anxiety disorder (SAD) is associated with heightened sensitivity to threat cues, typically represented by emotional facial expressions. To examine if this bias can be transferred to a general hypersensitivity or whether it is specific to disorder relevant cues, we investigated electrophysiological correlates of emotional word processing (alpha activity and event-related potentials) in 20 healthy participants and 20 participants with SAD. The experimental task was a silent reading of neutral, positive, physically threatening and socially threatening words (the latter were abusive swear words) while responding to a randomly presented dot. Subsequently, all participants were asked to recall as many words as possible during an unexpected recall test. Participants with SAD showed blunted sensory processing followed by a rapid processing of emotional words during early stages (early posterior negativity – EPN). At later stages, all participants showed enhanced processing of negative (physically and socially threatening) compared to neutral and positive words (N400). Moreover, at later processing stages alpha activity was increased specifically for negative words in participants with SAD but not in healthy controls. Recall of emotional words for all subjects was best for socially threatening words, followed by negative and positive words irrespective of social anxiety. The present findings indicate that SAD is associated with abnormalities in emotional word processing characterised by early hypervigilance to emotional cues followed by cognitive avoidance at later processing stages. Most importantly, the specificity of these attentional biases seems to change as a function of time with a general emotional bias at early and a more specific bias at later processing stages.     

Electrophysiological evidence for greater attention to threat when cognitive control resources are depleted

In this study, we investigated the time course of attentional bias for threat-related (angry) facial expressions under conditions of high versus low cognitive (working memory) load. Event-related potential (ERP) and reaction time (RT) data were recorded while participants viewed pairs of faces (angry paired with neutral face) displayed for 500 ms and followed by a probe. Participants were required to respond to the probe while performing a concurrent task of holding in working memory a sequence of digits that were either in the same order (low memory load) or in a random mixed order (high memory load). The ERP results revealed that higher working memory load resulted in enhanced lateralized neural responses to threatening relative to neutral faces, consistent with greater initial orienting of attention to threatening faces (early N2pc: 180–252 ms) and enhanced maintenance of processing representations of threat (late N2pc, 252–320 ms; SPCN, 320–500 ms). The ERP indices showed significant positive relationships with each other, and also with the behavioral index of attentional bias to threat (reflected by faster RTs to probes replacing angry than neutral faces at 500 ms), although the latter index was not significantly influenced by memory load. Overall, the findings indicate that depletion of cognitive control resources, using a working memory manipulation, increases the capacity of task-irrelevant threat cues to capture and hold attention.     

Stereotype threat,test anxiety,and mathematics performance

We investigated the combined effects of stereotype threat and trait test anxiety on mathematics test performance. Stereotype threat and test anxiety interacted with each other in affecting performance. Trait test anxiety predicted performance only in a diagnostic condition that prevented stereotype threat by stereotype denial. A state measure of fear of the test mediated this influence. However, stereotype threat reduced the performance of low test-anxious participants to the level of high test-anxious participants. Thus, stereotype threat affected persons low in test anxiety but not persons high in test anxiety. Both phenomena apparently share common mechanisms through which they impair performance.     

Patterns of attention to threat across tasks in behaviorally inhibited children at risk for anxiety

Although attention bias towards threat has been causally implicated in the development and maintenance of fear and anxiety, the expected associations do not appear consistently. Reliance on a single task to capture attention bias, in this case overwhelmingly the dot‐probe task, may contribute to this inconsistency. Comparing across attentional bias measures could help capture patterns of behavior that have implications for anxiety. This study examines the patterns of attentional bias across two related measures in a sample of children at temperamental risk for anxiety. Children (Mean_age = 10.19 ± 0.96) characterized as behaviorally inhibited (N = 50) or non‐inhibited (N = 64) via parent‐report completed the dot‐probe and affective Posner tasks to measure attentional bias to threat. Parent‐report diagnostic interviews assessed children's social anxiety. Behavioral inhibition was not associated with performance in the dot‐probe task, but was associated with increased attentional bias to threat in the affective Posner task. Cross‐task convergence was dependent on temperament, such that attention bias across the two tasks was only related in behaviorally inhibited children. Finally, children who were consistently biased across tasks (showing high or low attentional bias scores in both tasks, rather than high in one but low in the other) had higher levels of anxiety. Convergence across attention bias measures may be dependent on individuals' predispositions (e.g. temperament). Moreover, convergence of attention bias across measures may be a stronger marker of information processing patterns that shape socioemotional outcomes than performance in a single task.     

Attending to threat: Race-based patterns of selective attention

The present research investigated the extent to which the stereotype that young Black men are threatening and dangerous has become so robust and ingrained in the collective American unconscious that Black men now capture attention, much like evolved threats such as spiders and snakes. Specifically, using a dot-probe detection paradigm, White participants revealed biased attention toward Black faces relative to White faces (Study 1). Because the faces were presented only briefly (30-ms), the bias is thought to reflect the early engagement of attention. The attentional bias was eliminated, however, when the faces displayed averted eye-gaze (Study 2). That is, when the threat communicated by the Black faces was attenuated by a relevant, competing socio-emotional cue—in this case, averted eye-gaze—they no longer captured perceivers’ attention. Broader implications for social cognition, as well as public policies that reify these prevailing perceptions of young Black men are discussed.     

A lexicon of attention: from cognitive science to phenomenology

This article tries to create a bridge of understanding between cognitive scientists and phenomenologists who work on attention. In light of a phenomenology of attention and current psychological and neuropsychological literature on attention, I translate and interpret into phenomenological terms 20 key cognitive science concepts as examined in the laboratory and used in leading journals. As a preface to the lexicon, I outline a phenomenology of attention, especially as a dynamic three-part structure, which I have freely amended from the work of phenomenologist and Gestalt philosopher Aron Gurwitsch (1901–1973). As a conclusion, I discuss the nature of subjectivity in attention and attention research, and whether attention might be the same as consciousness.     

Selective attention for masked and unmasked threatening words in anxiety: Effects of trait anxiety, state anxiety and awareness

We investigated the effects of awareness on selective attention for masked and unmasked verbal threat material using a computerised version of the emotional Stroop. Participants were assigned to the high trait anxious (HTA) and low trait anxious (LTA) groups on the basis of questionnaire scores, and state anxiety was manipulated within participants through the threat of electric shock. To investigate the effects of awareness on responses to threat, the mode of exposure was blocked such that half the participants received masked trials before the unmasked trials, whereas the other half received the reverse order. The results revealed that there was no difference between the HTA and LTA groups in responses to threat for those who received the masked trials before the unmasked trials. However, when unmasked trials were presented before the masked trials HTA individuals were significantly slower to respond to both masked and unmasked threat words compared to the LTA group, and these effects were not further modified by participants' state anxiety status. The results are discussed in terms of the automatic nature of threat processing in anxiety.     

Selective attention in major depression: clinical retardation and cognitive inhibition]

Relationships between clinical retardation (measured by the Hamilton Depression Inventory) and selective attention (measured with a computerized version of the Stroop word colour test) were studied in a population of 21 depressed patients. Stroop interference was higher in depressed patients than in normals. Desynchronized presentations of the distractor and the target and intervals between responses and succeeding stimuli permitted depressed subjects to respectively apply and lift inhibition of the distractor so that their interference was reduced to control levels. Finally, successive inhibition scores were correlated with the retardation score in depressed subjects. The results are consistent with the hypothesis of a retardation in the application and the lifting of cognitive inhibition in depression.     

Contrasting two accounts of anxiety-linked attentional bias: selective attention to varying levels of stimulus threat intensity

Previous research has established that clinical anxiety patients and nonclinical populations with high levels of anxiety vulnerability characteristically orient attention toward moderately threatening stimuli. In contrast, populations with low levels of anxiety vulnerability typically orient attention away from such stimuli. The differing experimental predictions generated by 2 classes of hypothetical explanation for this anxiety-linked attentional discrepancy were tested, using attentional probe methodology to compare the attentional responses of high and low trait anxious individuals to facial stimuli of differing threat intensities. The results support the view that all individuals orient attention away from mildly threatening stimuli and toward strongly threatening stimuli, with differences in anxiety vulnerability reflecting the intensity of stimulus threat required to elicit the attentional vigilance response.
