Depressed individuals display biased attention for emotional information when stimuli are presented for relatively "long" (e.g., 1s) durations. The current study examined whether attentional biases are sustained over a much longer period. Specifically, clinically depressed and never depressed young adults simultaneously viewed images from four emotion categories (sad, threat, positive, neutral) for 30s while line of visual gaze was assessed. Depressed individuals spent significantly more time viewing dysphoric images and less time viewing positive images than their never depressed counterparts. Time course analyses indicated that these biases were maintained over the course of the trial. Results suggest that depressed participants' attentional biases for dysphoric information are sustained for relatively long periods even when other emotional stimuli are present. Mood congruent information-processing biases appear to be a robust feature of depression and may have an important role in the maintenance of the disorder.

    • "The advantage of using emotional faces is that they are more likely to be ecologically valid than words (Gross, 2005) and are better at attracting attention due to their higher interpersonal relevance. Based on previous studies of eye movement (Eizenman et al., 2003; Kellough et al., 2008) and reaction time tasks (Gotlib, Kasch, et al., 2004; Gotlib, Krasnoperova, et al., 2004), we hypothesized that depressed participants would show a negative bias in the maintenance of gaze specifically with regards to sad facial expressions (i.e. duration of the first fixation and total fixation time) but not in the orientation of gaze (i.e. "

    ABSTRACT: Background and objectives According to cognitive models, attentional biases in depression play key roles in the onset and subsequent maintenance of the disorder. The present study examines the processing of emotional facial expressions (happy, angry, and sad) in depressed and non-depressed adults. Methods Sixteen patients with Major Depressive Disorder (MDD) and 34 never-depressed controls (ND) completed an eye-tracking task to assess different components of visual attention (orienting attention and maintenance of attention) in the processing of emotional faces. Results Compared to ND, participants with MDD showed a negative attentional bias in attentional maintenance indices (i.e. first fixation duration and total fixation time) for sad faces. This attentional bias was positively associated with the severity of depressive symptoms. Furthermore, the MDD group spent a marginally less amount of time viewing happy faces compared with the ND group. No differences were found between the groups with respect to angry faces and orienting attention indices. Limitations The current study is limited by its cross-sectional design. Conclusions These results support the notion that attentional biases in depression are specific to depression-related information and that they operate in later stages in the deployment of attention.

    • "In the present study we examined attentional biases in both current and remitted depressed individuals in which participants' gaze was continuously recorded while they viewed emotional faces. First, in this study, facial expressions of different emotional contents (angry, sad, happy and neutral faces) were presented, compared to the presentation of emotional scenes or emotional words in most of the above mentioned studies (Caseras et al., 2007; Eizenman et al., 2003; Kellough et al., 2008). The main purpose of the present study was to investigate attentional interference among participants who are currently depressed, remitted depressed and among healthy controls by determining interference for negative stimuli (e.g., sad faces) and to establish whether this interference is evident at an early (first fixation), or late (maintained fixation) stage of information processing.

    ABSTRACT: Cognitive theories of depression propose that depressed individuals preferentially attend to negative information and that such cognitive biases constitute important vulnerability and maintenance factors for the disorder. Most studies examined this bias by registration of response latencies. The present study employed a direct and continuous measurement of attentional processing for emotional stimuli by recording eye movements. Currently depressed (CD), remitted depressed (RD) and healthy control (HC) participants viewed slides presenting sad, angry, happy and neutral facial expressions. For each expression, four components of visual attention were analyzed: first fixation, maintained fixation, relative fixation frequency and glance duration. Results showed that healthy controls were characterized by longer gaze duration for happy faces compared to currently depressed individuals but not compared to remitted depressed individuals. Both patient groups (CD, RD) demonstrated longer maintained fixation (dwelling time) on all emotional faces compared to healthy controls. The present findings are in line with the presumption that depression is associated with a loss of elaborative processing of positive stimuli that characterizes healthy controls. Importantly, successful remission of depression (RD group) may result in positive attentional processing as no group differences were found between healthy controls and remitted patients on glance duration for happy faces.

    • "Total time attending to each face was obtained by estimating the fixation time to each AOI, referred to as the total time that participants fixate on the emotional face area and on the neutral face area during the 3500 ms period. This indicator has been employed in previous research (e.g., Kellough et al., 2008). Pupil diameter was sampled for visual fixations in each of the two AOIs across the trials, and comprised of the average dilation for fixations made to each face over the 3500 ms period. "
