RESUMO

Background and aims: Theories posit that the combination of external (e.g. cue exposure) and internal (e.g. attention biases) factors contributes to the development of game craving. Nevertheless, whether different components of attentional biases (namely, engagement bias and disengagement bias) play separate roles on game craving has not been fully elucidated. We aimed to examine the associations between two facets of attentional biases and game craving dynamics under a daily life setting. Methods: Participants (110 regular internet game players) accomplished the modified attentional assessment task in the laboratory, after which they entered a 10-day ecological momentary assessment (EMA) to collect data on their momentary game craving and occurrence of game-related events at five different time points per day. Results: We found that occurrence of game-related events was significantly associated with increased game craving. Moreover, attentional disengagement bias, instead of engagement bias, bore on the occasional level variations of game craving as moderating variables. Specifically, attentional disengagement bias, not engagement bias, was associated with a greater increase in game craving immediately after encountering a game-related event; however, neither attentional engagement bias nor disengagement bias was associated with the craving maintenance after a relatively long period. Discussion and conclusions: The present study highlights the specific attentional processes involved in game craving dynamics, which could be crucial for designing interventions for attentional bias modification (ABM) in Internet Gaming Disorder (IGD) populations.

RESUMO

The current work aimed to uncover the pattern of attention given to external comparison standards when engaged in social judgments. In a series of 5 experiments (N = 463), a Modified Spatial Cueing Task provided evidence for a general Comparison Induced Delay (CID), but found no signs of visuospatial attention (Pilot, Study 1 & 2). However, the CID did not occur if cues did not remain visually available throughout the trials (Study 3 & 4). Heterogeneity in results prompted the use of a single-paper meta-analysis including all secondary studies. A consistent CID effect was found across studies when standards remained visually available (K = 5), but not when they were masked (K = 2). No direct signs of visuospatial attentional bias were found. These results suggest that the attentional cost of engaging with external comparisons is mainly cognitive in nature, although a minor reoccurring visual component could not be excluded.

RESUMO

Attentional deficits as well as attentional biases towards negative material are related to major depression and might maintain chronicity. However, studies investigating attentional deficits and attentional biases in chronic, treatment-resistant depressed are lacking. The aim of the current study was to compare measures of attentional deficits and attentional bias between chronic, treatment-resistant depressed outpatients and never-depressed control participants. Attentional deficits were assessed with the attentional control scale (ACS) and the Stroop Color naming task. Attentional bias was measured with the exogenous cueing task (ECT) and an emotional Stroop task. Chronic, treatment-resistant depressed patients (n = 80) showed significantly more attentional deficits than never-depressed controls (n = 113) on the ACS and Stroop color-naming task. However, in contrast with hypotheses, no differences were found between chronic, treatment-resistant depressed patients and never-depressed individuals on the ECT or emotional Stroop task. The current findings indicate that chronic, treatment-resistant depressed patients present attentional deficits. The results however question whether this patient group shows attentional biases for negative material. Future research should include comparisons of chronic, treatment-resistant and non-chronically depressed patients. If replicated, these current results might indicate that focusing on improving attentional deficits could be a more promising target for treatment than addressing attentional biases.

RESUMO

Contemporary debates about addressing inequality require a common, accurate understanding of the scope of the issue at hand. Yet little is known about who notices inequality in the world around them and when. Across five studies (N = 8,779) employing various paradigms, we consider the role of ideological beliefs about the desirability of social equality in shaping individuals' attention to-and accuracy in detecting-inequality across the class, gender, and racial domains. In Study 1, individuals higher (versus lower) on social egalitarianism were more likely to naturalistically remark on inequality when shown photographs of urban scenes. In Study 2, social egalitarians were more accurate at differentiating between equal versus unequal distributions of resources between men and women on a basic cognitive task. In Study 3, social egalitarians were faster to notice inequality-relevant changes in images in a change detection paradigm indexing basic attentional processes. In Studies 4 and 5, we varied whether unequal treatment adversely affected groups at the top or bottom of society. In Study 4, social egalitarians were, on an incentivized task, more accurate at detecting inequality in speaking time in a panel discussion that disadvantaged women but not when inequality disadvantaged men. In Study 5, social egalitarians were more likely to naturalistically point out bias in a pattern detection hiring task when the employer was biased against minorities but not when majority group members faced equivalent bias. Our results reveal the nuances in how our ideological beliefs shape whether we accurately notice inequality, with implications for prospects for addressing it.

RESUMO

INTRODUCTION: Altered attention to threatening stimuli at initial and sustained stages of processing may be dissociable dimensions that influence the development and maintenance of transdiagnostic symptoms of anxiety, such as vigilance, and possibly require distinct intervention. Attention bias modification (ABM) interventions were created to implicitly train attention away from threatening stimuli and have shown efficacy in treating anxiety. ABM alters neurocognitive functioning during initial stages of threat processing, but less is known regarding effects of ABM on neural indices of threat processing at sustained (i.e., intermediate and late) stages, or if ABM-related neural changes relate to symptom response. The current study utilized pupillary response as a temporally sensitive and cost-effective peripheral marker of neurocognitive response to ABM. MATERIALS AND METHODS: In a randomized controlled trial, 79 patients with transdiagnostic anxiety provided baseline data, 70 were randomized to receive eight sessions of twice-weekly ABM (n = 49) or sham training (n = 21), and 65 completed their assigned treatment condition and returned for post-training assessment. RESULTS: Among ABM, but not sham, patients, pupillary response to threat words during initial and intermediate stages decreased from pre- to post-training. Pre- to post-training reductions in intermediate and late pupillary response to threat were positively correlated with reductions in patient-reported vigilance among ABM, but not sham, patients. CONCLUSIONS: All measured stages of threat processing had relevance in understanding the neural mechanisms of ABM, with overlapping yet dissociable roles exhibited within a single neurophysiological marker across an initial-intermediate-late time continuum. Pupillometry may be well suited to measure both target engagement and treatment outcome following ABM.

RESUMO

Theoretical models propose that attentional biases might account for the maintenance of social anxiety symptoms. However, previous eye-tracking studies have yielded mixed results. One explanation is that existing studies quantify eye-movements using arbitrary, experimenter-defined criteria such as time segments and regions of interests that do not capture the dynamic nature of overt visual attention. The current study adopted the Eye Movement analysis with Hidden Markov Models (EMHMM) approach for eye-movement analysis, a machine-learning, data-driven approach that can cluster people's eye-movements into different strategy groups. Sixty participants high and low in self-reported social anxiety symptoms viewed angry and neutral faces in a free-viewing task while their eye-movements were recorded. EMHMM analyses revealed novel associations between eye-movement patterns and social anxiety symptoms that were not evident with standard analytical approaches. Participants who adopted the same face-viewing strategy when viewing both angry and neutral faces showed higher social anxiety symptoms than those who transitioned between strategies when viewing angry versus neutral faces. EMHMM can offer novel insights into psychopathology-related attention processes.

RESUMO

Facilitated attention toward angry stimuli (attention bias) may contribute to anger proneness and temper outbursts exhibited by children with high irritability. However, most studies linking attention bias and irritability rely on behavioral measures with limited precision and no studies have explored these associations in young children. The present study explores irritability-related attention biases toward anger in young children (N = 128; ages 4-7 years) engaged in a dot-probe task with emotional faces, as assessed with event-related brain potential (ERP) indices of early selective attention and multi-method assessment of irritability. Irritability assessed via semi-structured clinical interview predicted larger anterior N1 amplitudes to all faces. In contrast, irritability assessed via a laboratory observation paradigm predicted reduced P1 amplitudes to angry relative to neutral faces. These findings suggest that altered early attentional processing occurs in young children with high irritability; however, the nature of these patterns may vary with methodological features of the irritability assessments. Future investigations using different assessment tools may provide greater clarity regarding the underlying neurocognitive correlates of irritability. Such studies may also contribute to the ongoing debates about how to best define and measure irritability across the developmental spectrum in a manner that is most informative for linkage to neural processes.

RESUMO

Generalized Anxiety Disorder (GAD) is a prevalent, impairing, and undertreated psychiatric disorder. We examined if a home-based computerized treatment program can feasibly be delivered and successfully treat GAD symptoms. Using a randomized control trial, we compared three active groups receiving computerized sequenced Attention Bias Modification (ABM) followed by Applied Relaxation psychoeducation (AR-pe), the reversed sequence of AR-pe and ABM, and a simultaneous ABM and AR-pe group to an assessment only control group. The participants comprised 169 adults with a diagnosis of GAD. We asked participants to complete as many as twenty-four 30-min sessions of an at-home computerized treatment program over 12 weeks. The control group received 24 brief assessment questionnaires as well as assessments of attention bias. Results from intent-to-treat analyses show faster rate of improvement for symptoms of anxiety as measured by the Hamilton Anxiety Rating Scale (HAM-A) over time in groups that received active training in contrast to the clinical monitoring (CM) control group. Follow-up analyses revealed that both sequenced groups improved in anxiety when compared to the control group, while the simultaneous group did not outperform the control group. Results suggest that sequenced delivery of ABM and AR, may be a viable home-based treatment option for individuals with GAD who have limited access to resources or are otherwise unable to seek available treatments that require engagement outside of the home.

RESUMO

Socioeconomic disadvantage is associated with higher rates of psychopathology as well as hippocampus, amygdala and prefrontal cortex structure. However, little is known about how variations in brain morphometry are associated with socio-emotional risks for mood disorders in children growing up in families experiencing low income. In the current study, using structural magnetic resonance imaging, we examined the relationship between socioeconomic disadvantage and gray matter volume in the hippocampus, amygdala, and ventrolateral prefrontal cortex in a sample of children (n = 34) in middle childhood. Using an affective dot probe paradigm, we examined the association between gray matter volume in these regions and attentional bias to threat, a risk marker for mood disorders including anxiety disorders. We found that lower income-to-needs ratio was associated with lower bilateral hippocampal and right amygdala volume, but not prefrontal cortex volumes. Moreover, lower attentional bias to threat was associated with greater left hippocampal volume. We provide evidence of a relationship between income-related variations in brain structure and attentional bias to threat, a risk for mood disorders. Therefore, these findings support an environment-morphometry-behavior relationship that contributes to the understanding of income-related mental health disparities in childhood.

RESUMO

Experiment 1 aimed to establish "fearful" and "pleasant" functions for arbitrary stimuli (geometric shapes) by relating those stimuli to pictures of spiders and pets using a training version of the Implicit Relational Assessment Procedure (IRAP). The transformation of these functions for the arbitrary stimuli was assessed by exposing participants to a 'traditional' version of the IRAP, the Fear-IRAP employed by Leech et al. (2016, 2017). A broadly similar pattern of response biases was recorded for the Fear-IRAP as had been observed in the previously published studies. Experiment 1 thus supported the assumed but untested assumption that the relational context provided by the IRAP may both serve to establish and reveal fear-related response biases in arbitrary stimuli. A second experiment attempted to replicate the effects observed in Experiment 1 but using pictures of 'unfamiliar' Australian marsupials as arbitrary stimuli. The pattern of results obtained in Experiment 2 failed to replicate the pattern observed in Experiment 1, or that reported in the previously published studies by Leech et al. Overall, the findings suggest a possibly important boundary condition for the IRAP as a training and/or testing context for establishing fear-related response biases for arbitrary stimuli.

RESUMO

Prior research has shown that loneliness is associated with hypervigilance to social threats, with eye-tracking research showing lonely people display a specific attentional bias when viewing social rejection and social exclusion video footage (Bangee, Harris, Bridges, Rotenberg & Qualter, 2014; Qualter, Rotenberg, Barrett et al., 2013). The current study uses eye-tracker methodology to examine whether that attentional bias extends to negative emotional faces and negative social non-rejecting stimuli, or whether it could be explained only as a specific bias to social rejection/exclusion. It is important to establish whether loneliness relates to a specific or general attention bias because it may explain the maintenance of loneliness. Participants (N = 43, F = 35, Mage = 20 years and 2 months, SD = 3 months) took part in three tasks, where they viewed different social information: Task 1 - slides displaying four faces each with different emotions (anger, afraid, happy and neutral), Task 2 - slides displaying sixteen faces with varying ratios expressing happiness and anger, and Task 3 - slides displaying four visual scenes (socially rejecting, physically threatening, socially positive, neutral). For all three tasks, eye movements were recorded in real time with an eye-tracker. Results showed no association between loneliness and viewing patterns of facial expressions, but an association between loneliness and hypervigilant viewing of social rejecting stimuli. The findings indicate that lonely adults do not have a generalised hypervigilance to social threat, but have, instead, a specific attentional bias to rejection information in social contexts. Implications of the findings for interventions are discussed.

RESUMO

Objective This study aimed to analyse the psychological conditions and behaviour of a group of Chinese children and adolescents with obesity, and to develop an intervention for these young patients. Methods A group of 72 patients aged from 4 to 15 years were recruited from an obesity clinic. Patients, or the parents of children younger than 12 years, filled out a series of self-report questionnaires, and the responses were recorded and analysed. Results The 72 children and adolescents with obesity had a mean age of 9.14 ± 2.18 years. The body mass index-z scores of children with obesity showed a significant positive correlation with the level of impulsive behaviour, motivational impulses, and cognitive instability (inattention). Children with obesity quickly responded with extreme emotions, and these responses were positively correlated with the degree of obesity (slight, intermediate, or severe obesity). Conclusion Children and adolescents being treated for obesity have many underlying psychological problems, including emotional instability and impulsivity, and are prone to extreme emotional-psychological problems. These difficulties are positively correlated with the degree of obesity. Therefore, clinical treatment of these problems requires not only use of medication, improved nutrition, and healthy exercise, but also addressing underlying psychologic problems.

RESUMO

This article reviews the trajectory of our research program on selective attention, which has moved from basic research on the neural processes underlying selective attention to translational studies using selective attention as a neurobiological target for evidence-based interventions. We use this background to present a promising preliminary investigation of how genetic and experiential factors interact during development (i.e., gene × intervention interactions). Our findings provide evidence on how exposure to a family-based training can modify the associations between genotype (5-HTTLPR) and the neural mechanisms of selective attention in preschool children from lower socioeconomic status backgrounds.

RESUMO

Reinforcing efficacy of food, or the relationship between food prices and purchasing, is related to obesity status and energy intake in adults. Determining how to allocate resources for food is a decision making process influenced by executive functions. Attention to appetitive cues, as well as working memory capacity, or the ability to flexibly control attention while mentally retaining information, may be important executive functions involved in food purchasing decisions. In two studies, we examined how attention bias to food and working memory capacity are related to reinforcing efficacy of both high energy-dense and low energy-dense foods. The first study examined 48 women of varying body mass index (BMI) and found that the relationship between attentional processes and reinforcing efficacy was moderated by working memory capacity. Those who avoid food cues and had high working memory capacity had the lowest reinforcing efficacy, as compared to those with low working memory capacity. Study 2 systematically replicated the methods of study 1 with assessment of maintained attention in a sample of 48 overweight/obese adults. Results showed the relationship between maintained attention to food cues and reinforcing efficacy was moderated by working memory capacity. Those with a maintained attention to food and high working memory capacity had higher reinforcing efficacy than low working memory capacity individuals. These studies suggest working memory capacity moderated the relationship between different aspects of attention and food reinforcement. Understanding how decision making process are involved in reinforcing efficacy may help to identify future intervention targets.

RESUMO

The "organic" claim explicitly informs consumers about the food production method. Yet, based on this claim, people often infer unrelated food attributes. The current research examined whether the perceived advantage of organic over conventional food generalizes across different organic food types. Compared to whole organic foods, processed organic foods are less available, familiar and prototypical of the organic food category. In two studies (combined N = 258) we investigated how both organic foods types were perceived in healthfulness, taste and caloric content when compared to their conventional alternatives. Participants evaluated images of both whole (e.g., lettuce) and processed organic food exemplars (e.g., pizza), and reported general evaluations of these food types. The association of these evaluations with individual difference variables - self-reported knowledge and consumption of organic food, and environmental concerns - was also examined. Results showed that organically produced whole foods were perceived as more healthful, tastier and less caloric than those produced conventionally, thus replicating the well-established halo effect of the organic claim in food evaluation. The organic advantage was more pronounced among individuals who reported being more knowledgeable about organic food, consumed it more frequently, and were more environmentally concerned. The advantage of the organic claim for processed foods was less clear. Overall, processed organic (vs. conventional) foods were perceived as tastier, more healthful (Study 1) or equally healthful (Study 2), but also as more caloric. We argue that the features of processed food may modulate the impact of the organic claim, and outline possible research directions to test this assumption. Uncovering the specific conditions in which food claims bias consumer's perceptions and behavior may have important implications for marketing, health and public-policy related fields.

RESUMO

Arousing stimuli, either threat-related or pleasant, may be selected for priority at different stages within the processing stream. Here we examine the pattern of processing for non-task-relevant threatening (spiders: arousing to some) and pleasant stimuli (babies or chocolate: arousing to all) by recording the gaze of a spider Fearful and Non-fearful group while they performed a simple "follow the cross" task. There was no difference in first saccade latencies. Saccade trajectories showed a general hypervigilance for all stimuli in the Fearful group. Saccade landing positions corresponded to what each group would find arousing, such that the Fearful group deviated towards both types of images whereas the Non-fearful group deviated towards pleasant images. Secondary corrective saccade latencies away from threat-related stimuli were longer for the Fearful group (difficulty in disengaging) compared with the Non-fearful group. These results suggest that attentional biases towards arousing stimuli may occur at different processing stages.

RESUMO

BACKGROUND: Despite the range of available, evidence-based treatment options for Major Depressive Disorder (MDD), the rather low response and remission rates suggest that treatment is not optimal, yet. Computerized attention bias modification (ABM) trainings may have the potential to be provided as cost-effective intervention as adjunct to usual care (UC), by speeding up recovery and bringing more patients into remission. Research suggests, that a selective attention for negative information contributes to development and maintenance of depression and that reducing this negative bias might be of therapeutic value. Previous ABM studies in depression, however, have been limited by small sample sizes, lack of long-term follow-up measures or focus on sub-clinical samples. This study aims at evaluating the long-term (cost-) effectiveness of internet-based ABM, as add-on treatment to UC in adult outpatients with MDD, in a specialized mental health care setting. METHODS/DESIGN: This study presents a double-blind randomized controlled trial in two parallel groups with follow-ups at 1, 6, and 12 months, combined with an economic evaluation. One hundred twenty six patients, diagnosed with MDD, who are registered for specialized outpatient services at a mental health care organization in the Netherlands, are randomized into either a positive training (towards positive and away from negative stimuli) or a sham training, as control condition (continuous attentional bias assessment). Patients complete eight training sessions (seven at home) during a period of two weeks (four weekly sessions). Primary outcome measures are change in attentional bias (pre- to post-test), mood response to stress (at post-test) and long-term effects on depressive symptoms (up to 1-year follow-up). Secondary outcome measures include rumination, resilience, positive and negative affect, and transfer to other cognitive measures (i.e., attentional bias for verbal stimuli, cognitive control, positive mental imagery), as well as quality of life and costs. DISCUSSION: This is the first study investigating the long-term effects of ABM in adult outpatients with MDD, alongside an economic evaluation. Next to exploring the mechanism underlying ABM effects, this study provides first insight into the effects of combining ABM and UC and the potential implementation of ABM in clinical practice.

RESUMO

Since the programmatic Rosenhan study, there is a broad discussion of how to actively construct clinical realities on both "insane" and "sane" perspectives. To inform patients about the output of the psychometric questionnaires assessed at intake is a required task in many clinical routines. Information processing bias toward psychopathology may impact many clinical communications and thus lead to clinical errors. Based on an output of the commonly used Symptom Check List 90, case examples demonstrate various grades of balanced and unbalanced alternatives of how to consider the psychopathological as well as the unproblematic poles of Likert scales in discussing psychometric questionnaires at Session 1. We provide one clinical error related to client information at intake assessments and offer four therapeutic tasks that can serve as observable quality indicators of how to facilitate a balanced picture of the patients' burdens and capabilities: (1) validate individual problems, (2) isolate individual problems, (3) validate individual strengths, and (4) break through black and white thinking.

RESUMO

BACKGROUND: Incentive salience is a multidimensional construct that includes craving, drug value relative to other reinforcers, and implicit motivation such as attentional bias to drug cues. Laboratory cue reactivity (CR) paradigms have been used to evaluate marijuana incentive salience with measures of craving, but not with behavioral economic measures of marijuana demand or implicit attentional processing tasks. METHODS: This within-subjects study used a new CR paradigm to examine multiple dimensions of marijuana's incentive salience and to compare CR-induced increases in craving and demand. Frequent marijuana users (N=93, 34% female) underwent exposure to neutral cues then to lit marijuana cigarettes. Craving, marijuana demand via a marijuana purchase task, and heart rate were assessed after each cue set. A modified Stroop task with cannabis and control words was completed after the marijuana cues as a measure of attentional bias. RESULTS: Relative to neutral cues, marijuana cues significantly increased subjective craving and demand indices of intensity (i.e., drug consumed at $0) and Omax (i.e., peak drug expenditure). Elasticity significantly decreased following marijuana cues, reflecting sustained purchase despite price increases. Craving was correlated with demand indices (r's: 0.23-0.30). Marijuana users displayed significant attentional bias for cannabis-related words after marijuana cues. Cue-elicited increases in intensity were associated with greater attentional bias for marijuana words. CONCLUSIONS: Greater incentive salience indexed by subjective, behavioral economic, and implicit measures was observed after marijuana versus neutral cues, supporting multidimensional assessment. The study highlights the utility of a behavioral economic approach in detecting cue-elicited changes in marijuana incentive salience.

RESUMO

Excessive post-mortem processing after social situations, a core symptom of social anxiety disorder (SAD), is thought to contribute to the perpetuation of social anxiety by consolidating negative self-schemata. Empirical findings on actual mechanisms underlying this so-called Post-Event Processing (PEP) are still scarce. The present study sought to identify variables associated with the experience of PEP after real-life social situations in a sample of 49 individuals diagnosed with SAD. Using an ambulatory assessment approach, individuals were asked to report on each distressing social event experienced during one week. A total of 192 events were captured. Hierarchical linear modeling indicated that next to trait social anxiety, the type of social situation (performance vs. interaction situations), self-focused attention, safety behavior use, and negative affect predicted levels of PEP after social situations. These findings add to the growing literature that emphasizes the importance of situational factors for the experience of PEP, and highlight potential venues to prevent it.
