Information processing biases concurrently and prospectively predict depressive symptoms in adolescents: Evidence from a self-referent encoding task

Negative information processing biases have been hypothesised to serve as precursors for the development of depression. The current study examined negative self-referent information processing and depressive symptoms in a community sample of adolescents (N = 291, M_age at baseline = 12.34 ± 0.61, 53% female, 47.4% African-American, 49.5% Caucasian and 3.1% Biracial). Participants completed a computerised self-referent encoding task (SRET) and a measure of depressive symptoms at baseline and completed an additional measure of depressive symptoms nine months later. Several negative information processing biases on the SRET were associated with concurrent depressive symptoms and predicted increases in depressive symptoms at follow-up. Findings partially support the hypothesis that negative information processing biases are associated with depressive symptoms in a nonclinical sample of adolescents, and provide preliminary evidence that these biases prospectively predict increases in depressive symptoms.     

Negative emotional responses to motherhood-related support receipt during pregnancy predict postpartum depressive symptoms

Background and Objectives: Prenatal stress increases risk for postpartum depression. While social support availability may attenuate this risk, little research has examined support receipt during pregnancy, which has been linked to increased distress in other domains. This study assesses the implications of motherhood-related and motherhood-unrelated support receipt for daily distress during pregnancy and tests whether negative responsiveness to motherhood-related support predicts postpartum depression risk. Design and Method: Thirty-one pregnant women were recruited from the community for a 3-wave study (beginning at approximately 26 weeks gestation, 34 weeks gestation, and 4 weeks postpartum). Each wave included a survey of general characteristics (e.g. depressive symptoms) and a two-week diary period measuring mood, stress, and support. Results: A multilevel model analysis suggested that motherhood-related support predicted greater increases in daily distress than motherhood-unrelated support. Follow-up regression analysis showed that those who responded more negatively to motherhood-related support reported higher postpartum depressive symptoms. Conclusions: Although preliminary due to the sample size, the results suggest that how women interpret and respond to support may contribute to postpartum depression risk. Future research should focus on how mothers can more positively construe the support they receive in addition to how to increase the support available to them.     

Mapping the interplay among cognitive biases,emotion regulation,and depressive symptoms

Cognitive biases and emotion regulation (ER) difficulties have been instrumental in understanding hallmark features of depression. However, little is known about the interplay among these important risk factors to depression. This cross-sectional study investigated how multiple cognitive biases modulate the habitual use of ER processes and how ER habits subsequently regulate depressive symptoms. All participants first executed a computerised version of the scrambled sentences test (interpretation bias measure) while their eye movements were registered (attention bias measure) and then completed questionnaires assessing positive reappraisal, brooding, and depressive symptoms. Path and bootstrapping analyses supported both direct effects of cognitive biases on depressive symptoms and indirect effects via the use of brooding and via the use of reappraisal that was in turn related to the use of brooding. These findings help to formulate a better understanding of how cognitive biases and ER habits interact to maintain depressive symptoms.     

Biased attention and dysphoria: Manipulating selective attention reduces subsequent depressive symptoms

Selective attention for dysphoric stimuli has been observed in individuals with depression and those at risk for depression. To date, no studies have investigated the effects of directly manipulating selective attention for dysphoric stimuli on depressive symptoms. Mild to moderately depressed college students (N=34) were randomly assigned to complete 4 sessions of either attention training (AT) or no training (NT) during a two-week period. Participants completed self-reported assessments of depressive symptoms at baseline, post-training, and follow-up. Participants in the AT condition had a significantly greater decrease in depressive symptoms from baseline to follow-up than participants in the NT condition. This group difference was mediated by change in attention bias. Our findings suggest that biased attention may have a causal role in the maintenance of depressive symptoms.     

Individual differences in cognitive control over emotional material modulate cognitive biases linked to depressive symptoms

Deficient cognitive control over emotional material and cognitive biases are important mechanisms underlying depression, but the interplay between these emotionally distorted cognitive processes in relation to depressive symptoms is not well understood. This study investigated the relations among deficient cognitive control of emotional information (i.e. inhibition, shifting, and updating difficulties), cognitive biases (i.e. negative attention and interpretation biases), and depressive symptoms. Theory-driven indirect effect models were constructed, hypothesising that deficient cognitive control over emotional material predicts depressive symptoms through negative attention and interpretation biases. Bootstrapping analyses demonstrated that deficient inhibitory control over negative material was related to negative attention bias which in turn predicted a congruent bias in interpretation and subsequently depressive symptoms. Both shifting and updating impairments in response to negative material had an indirect effect on depression severity through negative interpretation bias. No evidence was found for direct effects of deficient cognitive control over emotional material on depressive symptoms. These findings may help to formulate an integrated understanding of the cognitive foundations of depressive symptoms.     

Maternal postpartum depressive symptoms predict delay in non-verbal communication in 14-month-old infants

We investigated the potential relationship between maternal depressive symptoms during the postpartum period and non-verbal communication skills of infants at 14 months of age in a birth cohort study of 951 infants and assessed what factors may influence this association. Maternal depressive symptoms were measured using the Edinburgh Postnatal Depression Scale, and non-verbal communication skills were measured using the MacArthur-Bates Communicative Development Inventories, which include Early Gestures and Later Gestures domains. Infants whose mothers had a high level of depressive symptoms (13+ points) during both the first month postpartum and at 10 weeks were approximately 0.5 standard deviations below normal in Early Gestures scores and 0.5–0.7 standard deviations below normal in Later Gestures scores. These associations were independent of potential explanations, such as maternal depression/anxiety prior to birth, breastfeeding practices, and recent depressive symptoms among mothers. These findings indicate that infants whose mothers have postpartum depressive symptoms may be at increased risk of experiencing delay in non-verbal development.     

Effects of attachment bereavement and pre-event conditions on subsequent depressive symptoms in older adults

A sample of 1,411 older adults (age 55+) who had been interviewed both prior to and after bereavement were studied, allowing for pre-event controls. Those who had lost a parent, spouse, or child had the strongest depressive reactions, as predicted by an attachment-bonding hypothesis; however, material losses were also related to depression. Although bereavement/loss events were clearly related to subsequent depression even after pre-event depression, resources, and events were controlled, certain pre-event characteristics were predictive of the bereavement/loss events, including prior undesirable events, age, and urban/rural residency. A further analysis of 1,007 persons with two post-event interviews (at 6-month to 1-year follow-up) revealed an initial depressive reaction to a bereavement/loss event, which then dissipated completely within 1 year's time. Generally, bereavement appeared to have limited etiologic importance.     

Social-cognitive processing and depressive symptoms in children: A comparison of measures

We assessed aspects of the reliability and validity of three measures of socialcognitive processing in children that have been developed to investigate the relations of such processes to childhood depression: the Children's Attributional Style Questionnaire (CASQ), the Children's Negative Cognitive Error Questionnaire (CNCEQ), and the Common Beliefs Inventory for Students (CBIS). In an unselected sample of 61 children, aged 8 to 12, the internal consistencies of the total scores on the CNCEQ and the CBIS were good; for the CASQ, it was only moderate. Internal consistencies of all subscale scores were inadequate. Despite this, several subscale and total scores were significantly associated with depressive symptoms, and the measures were generally correlated with each other. Although these data are encouraging concerning the role of social-cognitive processing in childhood depression, the field needs to develop psychometrically stronger measures and to test the role of social cognition in prospective studies of depression.This study was supported in part by a grant from the Spencer Foundation Awards to Young Scholars Program to the first author.

Learning biases predict a word order universal

How recurrent typological patterns, or universals, emerge from the extensive diversity found across the world's languages constitutes a central question for linguistics and cognitive science. Recent challenges to a fundamental assumption of generative linguistics-that universal properties of the human language acquisition faculty constrain the types of grammatical systems which can occur-suggest the need for new types of empirical evidence connecting typology to biases of learners. Using an artificial language learning paradigm in which adult subjects are exposed to a mix of grammatical systems (similar to a period of linguistic change), we show that learners' biases mirror a word-order universal, first proposed by Joseph Greenberg, which constrains typological patterns of adjective, numeral, and noun ordering. We briefly summarize the results of a probabilistic model of the hypothesized biases and their effect on learning, and discuss the broader implications of the results for current theories of the origins of cross-linguistic word-order preferences.     

Water contaminant levels interact with parenting environment to predict development of depressive symptoms in adolescents

Contaminants in drinking water, such as lead, nitrate, and arsenic, have been linked to negative physical health outcomes. We know less, however, about whether such pollutants also predict mental health problems and, if so, the conditions under which such effects are strongest. In this longitudinal study, we examined whether drinking water contaminants interact with negative family environments (parental psychological control) to predict changes in depressive symptoms in 110 adolescents—a developmental period when symptoms often first emerge. We found that for adolescents in psychologically controlling families, levels of drinking water contaminants prospectively predicted depressive symptoms 2 years later; this effect was not present in adolescents in non‐controlling families. Importantly, these associations were not accounted for by family‐ or community‐level socioeconomic resources, demographic features, or by the adolescents’ stress exposure. These findings highlight the interplay of physical and psychological environments in influencing depressive symptoms in adolescents.

Peer victimization, depressive symptoms, and high salivary cortisol predict poorer memory in children

The predictive relations of peer victimization, depressive symptoms, and salivary cortisol on memory in 168 children aged 12 at Time 1 (T1) were examined using a longitudinal design in which data were collected on four occasions over a 2-year period. Results indicated that: (1) peer victimization, depressive symptoms, and evening cortisol were stable over time, (2) peer victimization and elevated symptoms of depression were concurrently linked at each time, (3) T1 peer victimization predicted elevated symptoms of depression at T2 which in turn predicted lower cortisol levels at T3, and (4) controlling for earlier associations, T3 peer victimization, depressive symptoms, and higher morning and evening cortisol levels uniquely predicted memory deficits at T4. The links between elevated cortisol, symptoms of depression, and poor memory are consistent with published research on depressed adults and extend the findings to children exposed to peer victimization. These findings highlight that peer abuse is harmful and may impact children's long-term mental health and memory functioning.     

Negative interpretation bias as a mechanism of the relationship between rejection sensitivity and depressive symptoms

Rejection sensitivity and negative cognitive biases have been identified as important risk factors for depression. Rejection sensitivity is defined as the tendency to anxiously anticipate, easily perceive, and overreact to rejection. Although prior studies have found an association between one component of rejection sensitivity, the tendency to anxiously anticipate rejection, and depression, little is known about the mechanisms through which anxious anticipation of rejection might confer depression risk. One possibility is that rejection anticipation leads to negatively biased interpretations, a cognitive risk factor for depression. Results from two studies (one cross-sectional, one longitudinal) indicate that negative interpretation biases mediate the association between the anxious anticipation of rejection and depressive symptoms. These findings indicate that interpretation biases represent a mechanism through which anxious anticipation of rejection confers risk for depression, and suggest that interventions designed to challenge negative interpretations may help to decrease depression risk among individuals who anticipate rejection.     

Negative mood,depressive symptoms,and major depression after smoking cessation treatment in smokers with a history of major depressive disorder

Negative mood, depressive symptoms, and major depressive episodes (MDEs) were examined in 179 smokers with a history of major depression in a trial comparing standard smoking cessation treatment to treatment incorporating cognitive-behavioral therapy for depression (CBT-D). Early lapses were associated with relatively large increases in negative mood on quit date. Mood improved in the 2 weeks after quit date among those returning to regular smoking but not among those smoking moderately. Continuous abstinence was associated with short- and long-term reductions in depressive symptoms. MDE incidence during follow-up was 15.3% and was not associated with abstinence. Unexpected was that CBT-D was associated with greater negative mood and depressive symptoms and increased MDE risk. Results suggest complex bidirectional associations between affect and smoking outcomes.     

Early information processing biases in social anxiety

Considerable controversy persists regarding the nature of threat-related attention biases in social anxiety. Previous studies have not considered how variations in the temporal and energetic dimensions of affective stimulus delivery interact with anxiety-related individual differences to predict biased attention. We administered a visual dot-probe task, using faces that varied in affective intensity (mild, moderate, strong) and presentation rate (100, 500, 1,250 ms) to a selected sample. The high, compared to the low, socially anxious group showed vigilance towards angry faces and emotionally ambiguous faces more generally during rapid (100 ms) presentations. By 1,250 ms, there was only a non-specific motor slowing associated with angry faces in the high socially anxious group. Findings suggest the importance of considering both chronometric and energetic dimensions of affective stimuli when examining anxiety-related attention biases. Future studies should consider using designs that more closely replicate aspects of real-world interaction to study processing biases in socially anxious populations.

Thought suppression and memory biases during and after depressive moods

Previous research indicates that formerly depressed individuals engage in high levels of thought suppression that can mask depressive cognitions. However, suppression may also ironically foster a vigilance for unwanted thoughts that promotes uncertainty about ambiguous information and distorts memory. The present study tested this possibility. Formerly dysphoric, currently dysphoric, and never-dysphoric participants listened to a series of statements describing life events that were positive, negative, or ambiguous. In a subsequent recognition phase, participants reviewed a series of statements and rated each for the likelihood that it had been presented earlier. The recognition list included positive and negative disambiguated versions of the original items. Compared to the never-dysphoric group, formerly dysphoric individuals were more likely to endorse negative disambiguations. As predicted, this bias was associated with higher levels of thought suppression and greater uncertainty about the meaning of ambiguous situations, suggesting an ongoing conflict between positive and negative thoughts.     

Body-image and eating disturbances prospectively predict increases in depressive symptoms in adolescent girls: a growth curve analysis

Using data from a longitudinal community study (N = 231), the authors tested whether body-image and eating disturbances might partially explain the increase in depression observed in adolescent girls. Initial pressure to be thin, thin-ideal internalization, body dissatisfaction, dieting, and bulimic symptoms, but not body mass, predicted subsequent increases in depressive symptoms, as did increases in these risk factors over the study. There was also prospective support for each of the hypothesized mediational relations linking these risk factors to increases in depressive symptoms. Effects remained significant when other established gender-nonspecific risk factors for depression (social support and emotionality) were statistically controlled. Results provide support for the assertion that body-image and eating disturbances, operating above and beyond gender-nonspecific risk factors, contribute to the elevated depression in adolescent girls.
