Dual-task attention deficits in dysphoric mood.

The attentional functioning of nondysphoric, mildly dysphoric, and moderately to severely dysphoric college students was tested using the attentional blink (AB) paradigm. These groups performed equally well at reporting a single target appearing in a rapidly presented stream of stimuli. All groups showed an AB, with report sensitivity for a 2nd target being reduced when the 2 targets were presented less than 0.5 s apart. Nondysphoric and mildly dysphoric participants showed the same size ABs, but the ABs for moderately to severely dysphoric participants were larger and longer. As predicted, the results showed that moderately to severely dysphoric individuals have attentional impairments. These impairments, however, were evident only in the more demanding dual-task condition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Gaze behavior predicts memory bias for angry facial expressions in stable dysphoria.

Interpersonal theories suggest that depressed individuals are sensitive to signs of interpersonal rejection, such as angry facial expressions. The present study examined memory bias for happy, sad, angry, and neutral facial expressions in stably dysphoric and stably nondysphoric young adults. Participants' gaze behavior (i.e., fixation duration, number of fixations, and distance between fixations) while viewing these facial expressions was also assessed. Using signal detection analyses, the dysphoric group had better accuracy on a surprise recognition task for angry faces than the nondysphoric group. Further, mediation analyses indicated that greater breadth of attentional focus (i.e., distance between fixations) accounted for enhanced recall of angry faces among the dysphoric group. There were no differences between dysphoria groups in gaze behavior or memory for sad, happy, or neutral facial expressions. Findings from this study identify a specific cognitive mechanism (i.e., breadth of attentional focus) that accounts for biased recall of angry facial expressions in dysphoria. This work also highlights the potential for integrating cognitive and interpersonal theories of depression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Biases in visual orienting to negative and positive scenes in dysphoria: An eye movement study.

The study investigated biases for negative information in component processes of visual attention (initial shift vs. maintenance of gaze) in dysphoric and nondysphoric individuals. Eye movements were recorded while participants viewed a series of picture pairs depicting negative, positive, and neutral scenes (each pair presented for 3 s). Biases in initial orienting were assessed from the direction and latency of the initial shift in gaze, whereas biases in the maintenance of attention were assessed from the duration of gaze on the picture that was initially fixated. Results indicated that the dysphoric group showed a significantly greater bias to maintain gaze longer on negative pictures, relative to control pictures, compared with the nondysphoric group. There was no evidence of a dysphoria-related bias in initial shift of orienting to negative cues. Results are consistent with a depression-related bias that operates in the maintenance of attention on negative material. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of self-focused rumination on negative thinking and interpersonal problem solving.

Hypotheses about the effects of self-focused rumination on interpretations of events and interpersonal problem solving were tested in 3 studies with dysphoric and nondysphoric participants. Study 1 supported the hypothesis that dysphoric participants induced to ruminatively self-focus on their feelings and personal characteristics would endorse more negative, biased interpretations of hypothetical situations than dysphoric participants induced to distract themselves from their mood, or nondysphoric participants. Study 2 showed that dysphoric participants who ruminated were more pessimistic about positive events in their future than the other 3 groups. Study 3 showed that dysphoric ruminating participants generated less effective solutions to interpersonal problems than the other 3 groups. In Studies 1 and 3, dysphoric ruminating participants also offered the most pessimistic explanations for interpersonal problems and hypothetical negative events. In all 3 studies, dysphoric participants who distracted were as optimistic and effective in solving problems as nondysphoric participants.

Looking happy: The experimental manipulation of a positive visual attention bias.

Individuals with a positive visual attention bias may use their gaze to regulate their emotions while under stress. The current study experimentally trained differential biases in participants' (N = 55) attention toward positive or neutral information. In each training trial, one positive and one neutral word were presented and then a visual target appeared consistently in the location of the positive or neutral words. Participants were instructed to make a simple perceptual discrimination response to the target. Immediately before and after attentional training, participants were exposed to a stress task consisting of viewing a series of extremely negative images while having their eyes tracked. Visual fixation time to negative images, assessed with an eye tracker, served as an indicator of using gaze to successfully regulate emotion. Those participants experimentally trained to selectively attend to affectively positive information looked significantly less at the negative images in the visual stress task following the attentional training, thus demonstrating a learned aversion to negative stimuli. Participants trained toward neutral information did not show this biased gaze pattern. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Memory Accessibility, Mood Regulation, and Dysphoria: Difficulties in Repairing Sad Mood With Happy Memories?

Recent studies have suggested that mood-incongruency effects are due to mood-regulatory processes, in which people retrieve positive memories to repair negative moods. In Study 1, the authors investigated whether dysphoria influences the accessibility of autobiographical memories following a positive or a negative mood induction combined with subsequent rumination or distraction. The results showed a mood-repair effect for nondysphoric but not for dysphoric participants following rumination. In Study 2, participants were asked to either distract themselves or to recall positive autobiographical memories after a negative mood induction. Whereas nondysphoric participants' mood improved under both conditions, dysphoric participants' mood improved only after distraction. These results suggest that dysphoria is associated with a reduced ability to use mood-incongruent recall to repair sad moods. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The accuracy of self-monitoring and its relationship to self-focused attention in dysphoria and clinical depression.

The accuracy with which dysphoric (Study 1) and clinically depressed (Study 2) individuals make self-regulatory judgments about their own performance in the absence of external feedback and the extent to which this relates to trait self-focused attention (SFA) were examined. Relative to objective criteria, both dysphoric and depressed participants showed a positive judgment bias, overestimating the number of trials they had performed correctly. Relative to control participants, the dysphoric and depressed groups showed a reduction in the extent of this positive bias in that they judged error trials more accurately and correct trials less accurately. Although the dysphoric and depressed groups both reported elevated trait SFA, this did not correlate significantly with accuracy of self-judgment on the performance-monitoring task. Implications for self-regulation models of depression are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The influence of emotional valence on age differences in early processing and memory.

This study examined older and younger adults' attentional biases and subsequent incidental recognition memory for distracting positive, negative, and neutral words. Younger adults were more distracted by negative stimuli than by positive or neutral stimuli, and they correctly recognized more negative than positive words. Older adults, however, attended equally to all stimuli yet showed reliable recognition only for positive words. Thus, although an attentional bias toward negative words carried over into recognition performance for younger adults, older adults' bias appeared to be limited to remembering positive information.

Reward fails to alter response bias in depression.

Several different models postulate that depression is associated with decreased approach-related behavior. Relatively little has been done to date to specifically investigate this issue. In the present study, a signal-detection analysis was used to examine the response biases of dysphoric and nondysphoric female undergraduates during 3 payoff conditions: neutral, reward, and punishment. As predicted, the dysphoric subjects had a smaller change in bias from the neutral to the reward condition compared with the nondysphoric group. The 2 groups did not differ during the neutral and punishment conditions. These findings are consistent with the hypothesis that the left frontal hypoactivation observed in depression reflects a deficit in approach-related behavior.

Malleability of attentional bias for positive emotional information and anxiety vulnerability.

Recent research supports a causal link between attentional bias for negative emotional information and anxiety vulnerability. However, little is known about the role of positive emotional processing in modulating anxiety reactivity to stress. In the current study, we used an attentional training paradigm designed to experimentally manipulate the processing of positive emotional cues. Participants were randomly assigned to complete a computerized probe detection task designed to induce selective processing of positive stimuli or to a sham condition. Following training, participants were exposed to a laboratory stressor (i.e., videotaped speech), and state anxiety and positive affect in response to the stressor were assessed. Results revealed that individual variability in the capacity to develop an attentional bias for positive information following training predicted subsequent emotional responses to the stressor. Moreover, individual differences in social anxiety, but not depression, moderated the effects of the attentional manipulation, such that, higher levels of social anxiety were associated with diminished attentional allocation toward positive cues. The current findings point to the potential value of considering the role of positive emotional processing in anxiety vulnerability. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Dysphoria and decision making: Limited information use for evaluations of multiattribute targets.

The hypothesis was that dysphoric relative to nondysphoric individuals use less available, relevant information in decision making because of reduced attentional resources. Dysphoric and nondysphoric Ss evaluated 70 jobs, each of which was described in terms of 5 dimensions (e.g., friendliness of co-workers); there were 5 possible values for each dimension. In both studies, dysphoric relative to nondysphoric Ss used a smaller subset of information, yet did not simplify what information was used and did not combine the information in a more simple manner. The limited information use was not due to dysphoric Ss' systematically ignoring certain dimensions and was evident in both initial and final portions of the task. Dysphoric Ss spent as much time and reported using as much information and investing as much effort as nondysphoric Ss. Reported effort alone was related to actual information use.

The combined effect of gaze direction and facial expression on cueing spatial attention.

Empirical evidence shows an effect of gaze direction on cueing spatial attention, regardless of the emotional expression shown by a face, whereas a combined effect of gaze direction and facial expression has been observed on individuals' evaluative judgments. In 2 experiments, the authors investigated whether gaze direction and facial expression affect spatial attention depending upon the presence of an evaluative goal. Disgusted, fearful, happy, or neutral faces gazing left or right were followed by positive or negative target words presented either at the spatial location looked at by the face or at the opposite spatial location. Participants responded to target words based on affective valence (i.e., positive/negative) in Experiment 1 and on letter case (lowercase/uppercase) in Experiment 2. Results showed that participants responded much faster to targets presented at the spatial location looked at by disgusted or fearful faces but only in Experiment 1, when an evaluative task was used. The present findings clearly show that negative facial expressions enhance the attentional shifts due to eye-gaze direction, provided that there was an explicit evaluative goal present.

Facilitating a benign attentional bias reduces negative thought intrusions.

The causal role of biased attention in worry was investigated in an experiment in which high worriers were assigned either to a condition requiring attention to nonthreatening words and text while ignoring worry-related material or to a mixed-attention control condition. The former procedure led to fewer negative thought intrusions in a worry test (as rated by both participants and an assessor) than did the control condition. These findings suggest that attentional bias plays a causal role in worry and that its modification can reduce excessive worry. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mothers' and toddlers' coordinated joint focus of attention: Variations with maternal dysphoric symptoms.

This investigation compared the attention patterns of 40 toddlers and their mothers with or without dysphoric symptoms in a situation that allowed both common and independent foci of attention. Mother–toddler dyads with a dysphoric mother spent a smaller proportion of the session engaged in attention to an activity in common than did dyads with nondysphoric mothers. In addition, even when primarily attending elsewhere, nondysphoric mothers more extensively time-shared their attention between their child and a competing activity than did dysphoric mothers. Thus, dysphoric mothers appear to attend to an event in common with their children less frequently than do nondysphoric mothers in terms of both their primary focus of attention and their attentiveness to the child when primarily attending to a competing event.

Dysphoria and social interaction: an integration of behavorial confirmation and interpersonal perspectives

To investigate the process by which dysphoric persons are rejected by others, authors integrated behavioral confirmation and interpersonal theories of depression. The expectations of nondysphoric perceiver participants (college students) were manipulated, such that half expected to interact with a same-sex dysphoric target and half expected to interact with a same-sex nondysphoric target. The targets' actual mood status was consistent or inconsistent with these expectations. Pre- and postinteraction impressions, as well as postinteraction acceptance of partners, were solicited from perceivers and targets (N = 240). Audiotaped verbal behaviors were coded during the 1st and last 3 min of the interactions. Acceptance of targets and verbal behaviors were an interactive function of perceivers' expectancies and targets' mood status, such that dysphoric targets who were expected to be nondysphoric were the least accepted group and had the most dysfunctional interactions.

When are dysphoric individuals distressing to others and vice versa? Effects of friendship, similarity, and interaction task.

Examined several factors hypothesized to affect how dysphoric and nondysphoric individuals react to each other. 92 pairs of female college students participated in the study. Ss interacted with either a friend or stranger who had a similar or dissimilar dysphoria status in 3 tasks: a casual conversation, disclosure of a personal problem to the partner, and response to the partner's disclosure of a personal problem. Ss' moods, evaluations of their partners, and verbal behaviors were assessed. Dysphoric Ss exhibited characteristic negative mood and verbal content but did not elicit negative reactions from their partners. Negative reactions were most evident in dysphoric Ss' responses to dissimilar (nondysphoric) strangers, underscoring the need for greater attention to dysphoric individuals' perspective on their social interactions.

Attentional selection is biased toward mood-congruent stimuli.

One can exert significant volitional control over the attentional filter so that stimuli that are consistent with one's explicit goals are more likely to receive attention and become part of one's conscious experience. Here we pair a mood induction procedure with an inattentional blindness task to show that one's current mood has a similar influence on attention. A positive, negative, or neutral mood manipulation was followed by an attentionally demanding multiple-object tracking task. During the tracking task, participants were more likely to notice an unexpected face when its emotional expression was congruent with participants' mood. This was particularly true for the frowning face, which was detected almost exclusively by participants in the sad mood induction condition. This attentional bias toward mood-congruent stimuli provides evidence that one's temporary mood can influence the attentional filter, thereby affecting the information that one extracts from, and how one experiences the world.
