TL;DR: Attentional control theory is an approach to anxiety and cognition representing a major development of Eysenck and Calvo's (1992) processing efficiency theory and may not impair performance effectiveness when it leads to the use of compensatory strategies (e.g., enhanced effort; increased use of processing resources).
Abstract: Attentional control theory is an approach to anxiety and cognition representing a major development of Eysenck and Calvo's (1992) processing efficiency theory. It is assumed that anxiety impairs efficient functioning of the goal-directed attentional system and increases the extent to which processing is influenced by the stimulus-driven attentional system. In addition to decreasing attentional control, anxiety increases attention to threat-related stimuli. Adverse effects of anxiety on processing efficiency depend on two central executive functions involving attentional control: inhibition and shifting. However, anxiety may not impair performance effectiveness (quality of performance) when it leads to the use of compensatory strategies (e.g., enhanced effort; increased use of processing resources). Directions for future research are discussed.

TL;DR: Theories of anxiety and performance need to address at least two major issues: (1) the complexity and apparent inconsistency of the findings; and (2) the conceptual definition of task difficulty as mentioned in this paper.
Abstract: Anxiety often impairs performance of “difficult” tasks (especially under test conditions), but there are numerous exceptions. Theories of anxiety and performance need to address at least two major issues: (1) the complexity and apparent inconsistency of the findings; and (2) the conceptual definition of task difficulty. Some theorists (e.g. Humphreys & Revelle, 1984; Sarason, 1988) argue that anxiety causes worry, and worry always impairs performance on tasks with high attentional or short-term memory demands. According to the processing efficiency theory, worry has two main effects: (1) a reduction in the storage and processing capacity of the working memory system available for a concurrent task; and (2) an increment in on-task effort and activities designed to improve performance. There is a crucial distinction within the theory between performance effectiveness (= quality of performance) and processing efficiency (= performance effectiveness divided by effort). Anxiety characteristically impa...

TL;DR: It is concluded that overt visual attention is captured by both unpleasant and pleasant emotional content in emotional visual scenes.
Abstract: The eye-tracking method was used to assess attentional orienting to and engagement on emotional visual scenes. In Experiment 1, unpleasant, neutral, or pleasant target pictures were presented simultaneously with neutral control pictures in peripheral vision under instruction to compare pleasantness of the pictures. The probability of first fixating an emotional picture, and the frequency of subsequent fixations, were greater than those for neutral pictures. In Experiment 2, participants were instructed to avoid looking at the emotional pictures, but these were still more likely to be fixated first and gazed longer during the first-pass viewing than neutral pictures. Low-level visual features cannot explain the results. It is concluded that overt visual attention is captured by both unpleasant and pleasant emotional content.

TL;DR: In general, happy faces were identified more accurately, earlier, and faster than other faces, whereas judgments of fearful faces were the least accurate, the latest, and the slowest.
Abstract: Participants judged which of seven facial expressions (neutrality, happiness, anger, sadness, surprise, fear, and disgust) were displayed by a set of 280 faces corresponding to 20 female and 20 male models of the Karolinska Directed Emotional Faces database (Lundqvist, Flykt, & Ohman, 1998). Each face was presented under free-viewing conditions (to 63 participants) and also for 25, SO, 100, 250, and 500 msec (to 160 participants), to examine identification thresholds. Measures of identification accuracy, types of errors, and reaction times were obtained for each expression. In general, happy faces were identified more accurately, earlier, and faster than other faces, whereas judgments of fearful faces were the least accurate, the latest, and the slowest. Norms for each face and expression regarding level of identification accuracy, errors, and reaction times may be downloaded from www.psychonomic.org/archive/.

TL;DR: It is concluded that visual saliency of specific facial features--especially the smiling mouth--is responsible for facilitated initial orienting, which thus shortens detection of emotional facial expressions.
Abstract: In this study, the authors investigated how salient visual features capture attention and facilitate detection of emotional facial expressions. In a visual search task, a target emotional face (happy, disgusted, fearful, angry, sad, or surprised) was presented in an array of neutral faces. Faster detection of happy and, to a lesser extent, surprised and disgusted faces was found both under upright and inverted display conditions. Inversion slowed down the detection of these faces less than that of others (fearful, angry, and sad). Accordingly, the detection advantage involves processing of featural rather than configural information. The facial features responsible for the detection advantage are located in the mouth rather than the eye region. Computationally modeled visual saliency predicted both attentional orienting and detection. Saliency was greatest for the faces (happy) and regions (mouth) that were fixated earlier and detected faster, and there was close correspondence between the onset of the modeled saliency peak and the time at which observers initially fixated the faces. The authors conclude that visual saliency of specific facial features--especially the smiling mouth--is responsible for facilitated initial orienting, which thus shortens detection.

TL;DR: Research on the following topics is reviewed with respect to reading: (a) the perceptual span, (or span of effective vision), (b) preview benefit, (c) eye movement control, and (d) models of eye movements.
Abstract: Eye movements are now widely used to investigate cognitive processes during reading, scene perception, and visual search. In this article, research on the following topics is reviewed with respect to reading: (a) the perceptual span (or span of effective vision), (b) preview benefit, (c) eye movement control, and (d) models of eye movements. Related issues with respect to eye movements during scene perception and visual search are also reviewed. It is argued that research on eye movements during reading has been somewhat advanced over research on eye movements in scene perception and visual search and that some of the paradigms developed to study reading should be more widely adopted in the study of scene perception and visual search. Research dealing with "real-world" tasks and research utilizing the visual-world paradigm are also briefly discussed.

TL;DR: The results suggest that the term inhibition has been overextended and that researchers need to be more specific when discussing and measuring inhibition-related functions.
Abstract: This study used data from 220 adults to examine the relations among 3 inhibition-related functions. Confirmatory factor analysis suggested that Prepotent Response Inhibition and Resistance to Distractor Interference were closely related, but both were unrelated to Resistance to Proactive Interference. Structural equation modeling, which combined Prepotent Response Inhibition and Resistance to Distractor Interference into a single latent variable, indicated that 1 aspect of random number generation performance, task-switching ability, and everyday cognitive failures were related to Response-Distractor Inhibition, whereas reading span recall and unwanted intrusive thoughts were related to Resistance to Proactive Interference. These results suggest that the term inhibition has been overextended and that researchers need to be more specific when discussing and measuring inhibition-related functions.

TL;DR: It is indicated that biases in attention, memory, and interpretation, as well as repetitive negative thoughts, are common across emotional disorders, although they vary in form according to type of disorder.
Abstract: A review of recent research on cognitive processing indicates that biases in attention, memory, and interpretation, as well as repetitive negative thoughts, are common across emotional disorders, although they vary in form according to type of disorder. Current cognitive models emphasize specific forms of biased processing, such as variations in the focus of attention or habitual interpretative styles that contribute to the risk of developing particular disorders. As well as predicting risk of emotional disorders, new studies haveprovided evidence of a causal relationship between processing bias and vulnerability. Beyond merely demonstrating the existence of biased processing, research is thus beginning to explore the cognitive causes of emotional vulnerability, and their modification.
