Individual differences in positive and negative interpretive biases

Student subjects were given the task of writing down the spellings of a series of words (many of them homophones) presented auditorily. Some of the homophones had a negative and neutral interpretation, whereas others had a positive and neutral interpretation. Subjects low in trait anxiety (high extraversion, low neuroticism) produced more positive homophone interpretations than did those low in positive affectivity; this constitutes a positive interpretive bias. Subjects very high in negative affectivity (in terms of trait anxiety) produced more negative homophone interpretations than did those lower in trait anxiety; this constitutes a negative interpretive bias. Theoretical implications of these biases were discussed.     

Rumination and attention in major depression

Up until recently, it had been assumed that attentional biases for negative information do not exist in depression. However studies using post-conscious exposure durations have produced contradictory results. The limitations of common attentional tasks, suitability of stimulus materials and differences in stimulus duration times may have contributed to these inconsistencies. We aimed to address many of these issues and examine attentional responses in major depression at two post-conscious exposure times. We also investigated possible roles for rumination and distraction in increasing and lessening attentional biases for negative information. We used a fully controlled experimental design to test the effects of both induced and trait rumination and distraction on attention in patients with major depression and healthy controls. Attention was assessed using the dot-probe task. The findings revealed an attentional bias for negative information in depressed patients only at the longer post-conscious exposure duration. Furthermore although this bias was not influenced by either induced or trait distraction, it was related to trait rumination. Overall, the results showed that depression is associated with a strategic attentional bias towards negative information and that this bias is stronger in individuals who habitually ruminate.     

The indirect effect of attention bias on memory via interpretation bias: Evidence for the combined cognitive bias hypothesis in subclinical depression

Little research has investigated functional relations among attention, interpretation, and memory biases in depressed samples. The present study tested the indirect effect of attention bias on memory through interpretation bias as an intervening variable in a mixed sample of non-depressed and subclinically depressed individuals. Subclinically depressed and non-depressed individuals completed a spatial cueing task (to measure attention bias), followed by a scrambled sentences test (to measure interpretation bias), and an incidental free recall task (to measure memory bias). Bias-corrected bootstrapping yielded evidence for the hypothesised indirect effect model, in that an emotional bias in attention is related to a congruent bias in interpretative choices which are in turn reflected in memory. These findings extend previous research and provide further support for the combined cognitive bias hypothesis in depression. Theoretical and clinical implications of our findings are discussed.

Self-referential schemas and attentional bias predict severity and naturalistic course of depression symptoms

Attentional bias and self-referential schemas have been observed in numerous cross-sectional studies of depressed adults and are theorised to maintain negative mood. However, few longitudinal studies have examined whether maladaptive cognition predicts the course of depressive symptoms. Fifty-seven adults with elevated depression symptoms were assessed for negative attentional bias using a dot-probe task with eye-tracking and self-referential schemas using a self-referent encoding task. Participants subsequently completed five weekly depression symptom assessments. Participants with more negative self-referential schemas had higher baseline depression symptoms (r?=?.55). However, participants who spent more time attending to negative words showed greater symptom worsening over time (r?=?.42). The findings for negative self-referential schemas replicate past research, while the findings for negative attention bias represent the first evidence showing that attentional biases predict naturalistic symptom course. This work suggests that negative attention biases maintain depression symptoms and represent an important treatment target for neurocognitive therapeutics.     

Understanding associations between negatively biased attention and depression and social anxiety: positively biased attention is key

ABSTRACT

Background and objectives: Although research supports the premise that depressed and socially anxious individuals direct attention preferentially toward negative emotional cues, little is known about how attention to positive emotional cues might modulate this negative attention bias risk process. The purpose of this study was to determine if associations between attention biases to sad and angry faces and depression and social anxiety symptoms, respectively, would be strongest in individuals who also show biased attention away from happy faces.

Methods: Young adults (N?=?151; 79% female; M?=?19.63 years) completed self-report measures of depression and social anxiety symptoms and a dot probe task to assess attention biases to happy, sad, and angry facial expressions.

Results: Attention bias to happy faces moderated associations between attention to negatively valenced faces and psychopathology symptoms. However, attention bias toward sad faces was positively and significantly related to depression symptoms only for individuals who also selectively attended toward happy faces. Similarly, attention bias toward angry faces was positively and significantly associated with social anxiety symptoms only for individuals who also selectively attended toward happy faces.

Conclusions: These findings suggest that individuals with high levels of depression or social anxiety symptoms attend preferentially to emotional stimuli across valences.     

Mood-induced changes on the Implicit Association Test in recovered depressed patients

A mood induction paradigm was used to examine dysphoria-related changes in two types of cognitive processing in individuals who had previously experienced depression. Formerly depressed patients (n = 23) and never-depressed controls (n = 27) completed the Dysfunctional Attitudes Scale, a self-report measure of effortful processing, and performed the Implicit Association Test, an automatic-reaction time task that measures evaluative bias, before and after a negative-mood induction. The formerly depressed group showed both an increase in endorsement of dysfunctional attitudes and a more negative evaluative bias for self-relevant information after the induction, relative to controls--however, there was no association between the mood-linked changes observed on these two measures. The shift in evaluative bias shown by the formerly depressed group was similar to that seen in a group of 32 currently depressed individuals. These findings suggest that even a mild negative mood in formerly depressed individuals can reinstate some of the cognitive features observed in depression itself.     

Deployment of attention in clinical depression during symptom remission

The purpose of the current study was to investigate deployment of attention in clinically depressed patients during the process of symptom remission. Previous research indicates a non-depressed protective bias in attention whereas depressed individuals evidence no bias. A deployment-of-attention task based on negative, positive, and neutral adjectives was administered twice to 15 inpatients with major depression and 15 normal controls, at about 6 weeks apart. From test 1 to test 2, severity of patients' depressive symptoms improved significantly. Acutely depressed patients tended to show an attentional bias towards negative information whereas partially remitted patients manifested no attentional bias. Non-depressed individuals attended less to negative information than (acutely and partially remitted) depressed patients. Non-depressed participants but not depressed patients avoid negative information demonstrating a protective processing bias. Depressed patients are not characterized by a shift towards a pronounced protective pattern during symptom remission.     

Selective attention to emotional faces following recovery from depression

This study was designed to examine attentional biases in the processing of emotional faces in currently and formerly depressed participants and healthy controls. Using a dot-probe task, the authors presented faces expressing happy or sad emotions paired with emotionally neutral faces. Whereas both currently and formerly depressed participants selectively attended to the sad faces, the control participants selectively avoided the sad faces and oriented toward the happy faces, a positive bias that was not observed for either of the depressed groups. These results indicate that attentional biases in the processing of emotional faces are evident even after individuals have recovered from a depressive episode. Implications of these findings for understanding the roles of cognitive and interpersonal functioning in depression are discussed.

Individual differences in depression,induced mood,and perception of emotionally toned words

The associative network theory of emotion and memory, outlined by Bower (1981), predicts that depressed mood leads to biases which favour the perception of mood-congruent information. In this study, a lexical decision task was used to assess the effects of degree of depression and induced elation and depression on lexical decision times for positive and negative words. Subsequently, subjects were given a recall test for the words presented during the lexical decision task. The results partially offered support for perceptual bias. The data showed that in non-depressed and elation-induced subjects, decision times were differentially affected by hedonic tone. Words of positive nature were responded to significantly faster than were negative words. In mildly depressed and depression-induced, decision times were similar for both types of words (positive and negative). These findings are discussed in relation to the associative network model and a growing amount of empirical research on human emotion and cognition.     

Cognitive biases in three prediction tasks: A test of the cognitive model of depression

Cognitive therapy for depression is based on an assumption that depressed individuals have inaccurate, negative biases. Whether this assumption is accurate remains unresolved. Thus, this study sought to examine the relationship between depressive symptoms and bias in three sets of predictions (i.e., predictions of future life events, how one would be rated by a significant other, and performance on a vocabulary test). Following study announcements made to a subset of people pre-screened for depressive symptoms, 85 participants with widely varying depressive symptoms (17 of whom met diagnostic criteria for depression) made predictions on three judgment tasks and the outcomes for these tasks were assessed. Optimistic/pessimistic biases were related to depressive symptoms for each of the three tasks. Participants with high levels of depressive symptoms and depressed participants exhibited substantial pessimistic bias. Those high in depressive symptoms exhibited significant pessimistic bias on all three tasks. Participants meeting diagnostic criteria for depression exhibited pessimistic bias on two of three tasks. There was no evidence that depressive symptoms were associated with greater accuracy in judgments. Results are largely consistent with cognitive models of depression which postulate that depression is associated with pessimistic biases.     

Attention allocation in social anxiety during a speech

Cognitive models assume that social anxiety is associated with and maintained by biased information processing, leading to change in attention allocation, which can be measured by examining eye movement. However, little is known about the distribution of attention among positive, neutral and negative stimuli during a social task and the relative importance of positive versus negative biases in social anxiety. In this study, eye movement, subjective state anxiety and psychophysiology of individuals with high trait social anxiety (HSA) and low trait social anxiety (LSA) were measured during a speech task with a pre-recorded audience. The HSA group showed longer total fixation on negative stimuli and shorter total fixation on positive stimuli compared to the LSA group. We observed that the LSA group shifted attention away from negative stimuli, whereas the HSA group showed no differential attention allocation. The total duration of fixation on negative stimuli predicted subjective anxiety ratings. These results point to a negative bias as well as a lack of a positive bias in HSA individuals during social threat.     

Depression reduces perceptual sensitivity for positive words and pictures

There is evidence of maladaptive attentional biases for lexical information (e.g., Atchley, Ilardi, & Enloe, 2003; Atchley, Stringer, Mathias, Ilardi, & Minatrea, 2007) and for pictographic stimuli (e.g., Gotlib, Krasnoperova, Yue, & Joormann, 2004) among patients with depression. The current research looks for depressotypic processing biases among depressed out-patients and non-clinical controls, using both verbal and pictorial stimuli. A d′ measure (sensitivity index) was used to examine each participant's perceptual sensitivity threshold. Never-depressed controls evidenced a detection bias for positive picture stimuli, while depressed participants had no such bias. With verbal stimuli, depressed individuals showed specific decrements in the detection of positive person-referent words (WINNER), but not with positive non-person-referent words (SUNSHINE) or with negative words. Never-depressed participants showed no such differences across word types. In the current study, depression is characterised both by an absence of the normal positivistic biases seen in individuals without mood disorders (consistent with McCabe & Gotlib, 1995), and by a specific reduction in sensitivity for person-referent positive information that might be inconsistent with depressotypic self-schemas.     

Memory for emotional stories in high and low depressed children

Cognitive theories of depression emphasise a vicious circle linking depressed mood and biased recall towards negative information. In line with this, depressed adults show selectively enhanced recall for negative information. This recall bias is held to be mediated by increased accessibility of negative self-referent schemas formed as a result of adverse early experiences. Given this, surprisingly few studies have examined depression-related recall biases from a developmental perspective. Clinically depressed children have been found to show enhanced recall of negative adjectives, particularly when self-referent, but to date there is no evidence for similar recall biases in non-clinically depressed groups. The current study addressed this by investigating high and low non-clinically depressed children's (aged 5-11 years) recall of emotional stories. High depressed children showed enhanced recall of negative stories, relative to positive stories, compared to the low depressed group. This did not vary with age group. We conclude that, when child-oriented materials are used, depression-related biases in recall towards negative information are observable even in a non-clinical sample of children from 5 years of age.     

Mood-congruent bias and attention shifts in the different episodes of bipolar disorder

An “affective” go/no-go task was used in the different episodes of bipolar patients (euthymic, depressed, and manic) to examine (1) the presence of a mood-congruent attentional bias; and (2) the patients' ability to inhibit and invert associations between stimuli and responses through blocks. A group of healthy individuals served as controls. Results revealed a mood-congruent attentional bias: patients in the manic episode processed positive information faster, whereas those in the depressive episode processed negative information faster. In contrast, neither euthymic patients nor healthy individuals showed any mood-congruent biases. Furthermore, there was a shift cost across blocks for healthy individuals, but not for the patients. This may reflect a general impairment at selecting relevant information (e.g., in terms of disability to inhibit and invert associations between stimuli and responses) in bipolar participants, regardless of their episode. This state/trait dissociation in an episodic and chronic disorder such as bipolar disorder is important for its appropriate characterisation.     

Gender Differences in Self-Perception and Negative Recall Biases

This study investigated gender differences inthe accuracy of self-perceptions and whetherself-perception biases are related to negative recallbiases. Participants were 275 female and 213 malecollege students. Approximately 10% of the participantswere minorities (mostly African American and Asian). Ona masculine task, gender differences in self-perceptionswere found for three measures of accuracy: The accuracy of self-evaluations, calibration,and response bias. Females underestimated theirperformance, were less well calibrated, and showed amore conservative response bias than did males. Ashypothesized, no gender differences in the accuracy ofself-evaluations were found for feminine and neutraltasks. Participants' expectancies mediated the genderdifferences in post task self-evaluations ofperformance. In addition, evidence for a negative recallbias was found. Females were more likely than males torecall their mistakes even with performance and accuracyof self-evaluations controlled. The implications of females' greater self-perception biases onmasculine tasks are discussed and suggestions for futureresearch are made.     

Expectancy bias mediates the link between social anxiety and memory bias for social evaluation

Social anxiety (SA) involves a multitude of cognitive symptoms related to fear of evaluation, including expectancy and memory biases. We examined whether memory biases are influenced by expectancy biases for social feedback in SA. We hypothesised that, faced with a socially evaluative event, people with higher SA would show a negative expectancy bias for future feedback. Furthermore, we predicted that memory bias for feedback in SA would be mediated by expectancy bias. Ninety-four undergraduate students (55 women, mean age = 19.76 years) underwent a two-visit task that measured expectations about (Visit 1) and memory of (Visit 2) feedback from unknown peers. Results showed that higher levels of SA were associated with negative expectancy bias. An indirect relationship was found between SA and memory bias that was mediated by expectancy bias. The results suggest that expectancy biases are in the causal path from SA to negative memory biases for social evaluation.
