Pixelating Familiar People in the Media: Should Masking Be Taken at Face Value?

This study questions the effectiveness of masking faces by means of pixelation on television or in newspapers. Previous studies have shown that masking just the face leads to unacceptably high recognition levels, making it likely that participants also use other cues for recognition, such as hairstyle or clothes. In the current study we investigate this possibility by means of an identification task in which participants had to identify (partially) masked images of familiar people. To demonstrate that non-facial cues become increasingly important for recognition as faces are masked more strongly, we manipulated the size of the masked area and the degree of pixelation. Confirming our expectations, increasing the size of masked area or its level of deterioration led to lower recognition rates. More importantly, also an interaction effect between the two variables emerged, showing that additional visual information partly compensates the downswing in recognition when masking becomes stronger. Although in some conditions low recognition rates were found, masking was never a hundred percent effective, making it clear that the media should approach this issue with care. Implications of our findings and future directions are considere

Signals of threat do not capture, but prioritize, attention: a conditioning approach

Research suggests that threatening information captures attention more rapidly than neutral information. However, in most studies threat stimuli differ perceptually from neutral stimuli and are instrumental to perform the task, leaving the question unanswered whether threat is sufficient to capture attention. In experiment 1, we designed a visual search task with stimuli of equal salience (colored circles) that have the potential to lead to efficient search (10 ms/item). In experiment 2, one of the colors (conditioned stimulus, CS+) was made threatening by means of fear conditioning. Participants responded to a target presented in one of the circles. Overall, the search was faster on congruent trials (where the target was presented in the CS+) than on baseline trials (where the CS + was absent). Furthermore, the search was slower on incongruent trials (where the target was presented in another color than the CS+) than on baseline trials. The search on congruent trials was affected by set size (90 ms/item), but to a lesser extent than on baseline trials (105 ms/item). We conclude that threat prioritizes, but does not capture attention

Task relevance of emotional information affects anxiety-linked attention bias in visual search

Task relevance affects emotional attention in healthy individuals. Here, we investigate whether the association between anxiety and attention bias is affected by the task relevance of emotion during an attention task. Participants completed two visual search tasks. In the emotion-irrelevant task, participants were asked to indicate whether a discrepant face in a crowd of neutral, middle-aged faces was old or young. Irrelevant to the task, target faces displayed angry, happy, or neutral expressions. In the emotion-relevant task, participants were asked to indicate whether a discrepant face in a crowd of middle-aged neutral faces was happy or angry (target faces also varied in age). Trait anxiety was not associated with attention in the emotion-relevant task. However, in the emotion-irrelevant task, trait anxiety was associated with a bias for angry over happy faces. These findings demonstrate that the task relevance of emotional information affects conclusions about the presence of an anxiety-linked attention bias

For there is nothing either good or bad: a study of the mediating effect of interpretation bias on the association between mindfulness and reduced post-traumatic stress vulnerability

BACKGROUND: Despite increasing interest in the association between mindfulness and reduced trauma vulnerability, and the use of mindfulness in the latest interventions for Post-Traumatic Stress Disorder (PTSD), few studies have examined the mechanisms through which mindfulness may influence post-trauma psychopathology. The present study aimed to determine whether negative interpretation bias, the tendency to interpret ambiguous information as negative or threatening rather than positive or safe, mediates the association between higher levels of trait mindfulness and lower levels of PTSD symptoms. Negative interpretation bias was examined due to prior evidence indicating it is associated with being less mindful and post trauma psychopathology. METHODS: The study examined 133 undergraduate students who reported exposure to one or more potentially traumatic events in their lifetime. Participants completed self-report measures of trait mindfulness (Five Facet Mindfulness Questionnaire – Short Form; FFMQ-SF) and PTSD symptoms (Post-Traumatic Stress Disorder Checklist – Civilian version; PCL-C) as well an interpretation bias task that assessed the degree to which participants interpreted a range of everyday hypothetical scenarios to be threatening to their physical and/or psychological wellbeing. RESULTS: Results of a mediation analysis indicated a significant negative direct effect of trait mindfulness on PTSD symptomatology (p < .001). There was no evidence that negative interpretation bias mediated this relationship [BCa CI [-0.04, 0.03)], nor was it associated with trait mindfulness (p = .90) and PTSD symptomatology (p = .37). CONCLUSIONS: The results of the current study provide further evidence of the link between trait mindfulness and reduced post-trauma psychopathology while providing no support for the role of negative interpretation bias in this relationship.

Effects of intensity on emotion regulation strategy preferences are emotion-specific

Adaptive emotion regulation is characterized by the ability to flexibly select and switch between different strategies, depending on individual and contextual factors. Previous studies have shown that people prefer disengagement strategies to regulate more intense emotions, while they prefer engagement strategies to regulate less intense emotions. In this study, we investigated whether – in addition to the intensity of emotions – the discrete emotion type (disgust versus fear) also affects emotion regulation strategy preferences. A total of 401 students from three different universities completed an emotion regulation choice task in which they could choose between distraction and reappraisal to regulate their emotions in response to viewing high versus low intensity disgust- and fear-evoking pictures. We found that strategy choices did indeed depend on the nature of specific emotions, with distraction being preferred for regulating disgust, and reappraisal being preferred for regulating fear. Crucially, the nature of the emotion also qualified the previously reported effect of emotion intensity on strategy choice: Only for disgust- but not for fear-evoking pictures did participants show an increased preference for distraction over reappraisal with increased emotion intensity. Our results thus show that the effects of emotional intensity on emotion regulation strategy choice are emotion-specific and indicate that factors affecting emotion regulation strategy choice interact with each other

tDCS increases anxiety reactivity to intentional worry

While considerable experimental research has examined the impact of transcranial direct current stimulation (tDCS) on a range of cognitive processes associated with emotional pathology, the impact of tDCS on worry has been comparatively neglected. Given that anxiety pathology is characterised by motivated engagement in worry, and that frontal tDCS has the capacity to enhance goal-oriented cognition, it is important to examine whether tDCS would increase or ameliorate the cognitive and emotional effects of worry. In the current study we examined how tDCS influenced the anxiety response to worry, and the frequency of negative intrusive thoughts. We additionally examined whether stimulation delivered in isolation, or in combination with a mindful-focus task would augment the effects of tDCS. Ninety-seven (75 female) healthy participants received either active or sham anodal tDCS to the left dorsolateral prefrontal cortex, delivered either in isolation or concurrently with a mindful task (four conditions). The frequency of negative thoughtc intrusions was assessed before and after a period of instructed worry, and state anxiety was assessed across the study. Active tDCS was associated with significantly greater elevation in anxiety in response to the worry induction. No effects were observed on the frequency of negative thought intrusions, and the combined delivery of tDCS with the concurrent mindful task did not alter the pattern of observed effects. While inviting replication in a high anxious sample, the present results highlight the possibility that tDCS may interact with motivated engagement in negative patterns of cognition, such as worry, to produce greater emotional reactivity

Investigating the role of mental imagery use in the assessment of anhedonia

Anhedonia, or a deficit in the liking, wanting, and seeking of rewards, is typically assessed via self-reported in-the-moment emotional and motivational responses to reward stimuli and activities. Given that mental imagery is known to evoke emotion and motivational responses, we conducted two studies to investigate the relationship between mental imagery use and self-reported anhedonia. Using a novel Reward Response Scale (adapted from the Dimensional Anhedonia Rating Scale, DARS; Rizvi et al., 2015) modified to assess deliberate and spontaneous mental imagery use, Study 1 ( N  = 394) compared uninstructed and instructed mental imagery use, and Study 2 ( N  = 586) conducted a test of replication of uninstructed mental imagery use. Results showed that greater mental imagery use was associated with higher reward response scores (Study 1 & 2), and this relationship was not moderated by whether imagery use was uninstructed or instructed (Study 1). Importantly, mental imagery use moderated the convergence between reward response and depression scale measures of anhedonia, with lower convergence for those reporting higher mental imagery use (Study 1 & 2). Results suggest that higher spontaneous mental imagery use may increase self-reported reward response and reduce the convergence between reward response scale and depression questionnaire measures of anhedonia.
