Neurophysiological evidence for early modulation of amygdala activity by emotional reappraisal

How emotions unfold through time in the brain, and how fast they can be regulated by voluntary control, remain unresolved. Psychological accounts of emotion regulation posit cognitive reappraisal mechanisms may alter early emotion generative processes directly, whereas suppression impacts only later processing stages, after emotion has arisen. However, to date, there is no neurophysiological data concerning the precise latency of emotion regulation effects on the amygdala, a major emotion processing relay in the brain. Here we record amygdala activity from six patients undergoing surgery for pharmaco-resistant epilepsy during both reappraisal and suppression. We find that emotion reappraisal strategy, but not suppression, modulates early neural responses to emotional scenes during an extended period of time, starting 130 ms post-stimulus onset. Further, reappraisal produced earlier impact on amygdala responses to positive compared to negative scenes. Our results provide the first neurophysiological support for theoretical accounts of emotion regulation that postulate an early modulation of emotion generative processes by reappraisal.

Eye-gaze contingent attention training (ECAT): Examining the causal role of attention regulation in reappraisal and rumination

This study used a novel eye-gaze contingent attention training (ECAT) to test the prediction that attention regulation is involved in reappraisal and rumination. Sixty-six undergraduates were randomly assigned to either the control or the active training condition of the ECAT. Active ECAT comprised training in allocating attention toward positive words to efficiently create positive interpretations while receiving gaze-contingent feedback. Participants in the control condition freely generated interpretations without receiving gaze-contingent feedback. Active ECAT resulted in: 1) more sustained attention on positive information, in turn predicting greater reappraisal success to down-regulate negative emotions, and 2) larger reductions in state rumination after viewing negative scenes. Our results highlight the importance of considering attention mechanisms in understanding (and treating impaired) emotion regulation processes. These findings provide an important step towards the use of personalized attention training to build resources of resilience.

Imagery retrieval may explain why recall of negative scenes contains more accurate detail

We investigated whether the presence of imagery at retrieval was associated with the finding that negative pictures and scenes are recalled with greater perceptual detail. Participants were presented with 30 scenes taken from the International Affective Picture System that were rated either high or low on valence, but similarly on arousal. Recall was prompted with matched visual or verbal cues. During recall, participants reported any images that came to mind and rated them for vividness, whereas accuracy was rated independently. Imagery was described at test in response to over 60% of the stimuli. Whereas vividness was predicted by negative valence, images occurred more often in response to visual cues. The association of negative valence and visual cueing with better recall was observed only in the presence of reported imagery. These findings have important implications for models and experiments focusing on the recall and recognition of visual stimuli.

How the Dorsolateral Prefrontal Cortex Controls Affective Processing in Absence of Visual Awareness - Insights From a Combined EEG-rTMS Study.

The dorsolateral prefrontal cortex (DLPFC) plays a key role in the modulation of affective processing. However, its specific role in the regulation of neurocognitive processes underlying the interplay of affective perception and visual awareness has remained largely unclear. Using a mixed factorial design, this study investigated effects of inhibitory continuous theta-burst stimulation (cTBS) of the right DLPFC (rDLPFC) compared to an Active Control condition on behavioral (N = 48) and electroencephalographic (N = 38) correlates of affective processing in healthy Chinese participants. Event-related potentials (ERPs) in response to passively viewed subliminal and supraliminal negative and neutral natural scenes were recorded before and after cTBS application. We applied minimum-norm approaches to estimate the corresponding neuronal sources. On a behavioral level, we found evidence for reduced emotional interference by, and less negative and aroused ratings of negative supraliminal stimuli following rDLPFC inhibition. We found no evidence for stimulation effects on self-reported mood or the behavioral discrimination of subliminal stimuli. On a neurophysiological level, rDLPFC inhibition relatively enhanced occipito-parietal brain activity for both subliminal and supraliminal negative compared to neutral images (112–268 ms; 320–380 ms). The early onset and localization of these effects suggests that rDLPFC inhibition boosts automatic processes of “emotional attention” independently of visual awareness. Further, our study reveals the first available evidence for a differential influence of rDLPFC inhibition on subliminal versus supraliminal neural emotion processing. Explicitly, our findings indicate that rDLPFC inhibition selectively enhances late (292–360 ms) activity in response to supraliminal negative images. We tentatively suggest that this differential frontal activity likely reflects enhanced awareness-dependent down-regulation of negative scene processing, eventually leading to facilitated disengagement from and less negative and aroused evaluations of negative supraliminal stimuli.

An objective signature of emotional expressions and context integration within a single glance: evidence from electroencephalographic frequency-tagging

The ability to quickly and accurately extract someone's emotional state from their face is crucial for social interaction. Over the last decades, the processing of emotional expressions has been studied mainly using isolated faces. However, at the behavioral level, contextual information often leads to radical changes in the categorization of facial expressions, yet the underlying mechanisms are not well understood (Aviezer et al., 2017, Current Opinion in Psychology, 17, 47–54; Barrett et al., 2011, Current Directions in Psychological Science, 20, 286 –290). Here we examined the impact of emotional visual scenes on the perception of emotional expressions within a single glance by means of fast periodic visual stimulation (FPVS). We recorded 128-channel EEG while participants viewed 60s sequences with a dual frequency-tagging paradigm (Boremanse et al, 2013, Journal of Vision (11):6, 1-18). We presented faces and scenes simultaneously, with each stimulus set flickering at specific frequency (f1=4.61 Hz and f2=5.99 Hz; frequencies were counterbalanced across stimuli). Each sequence displayed different faces with the same emotional expression (disgust, fear, or joy) within either positive or negative valence visual scenes. Periodic EEG responses at the image presentation frequencies (4.61 Hz and 5.99 Hz) captured general visual processing of the emotional faces and scenes, while intermodulation components (e.g. f2-f1: 5.99 – 4.61 Hz = 1.38 Hz) captured the integration between the emotional expressions and their context. At the group-level, emotional expressions elicited right-lateralized occipito-temporal electrophysiological responses that were stronger for negative valence expressions (especially disgust). Similarly, negative scenes elicited stronger neural responses than positive scenes over the medial occipital region. Finally, and critically, we observed intermodulation components that were prominent over right occipito-temporal sites and showed increased response amplitude for negative scenes, thereby providing an objective demonstration of the perceptual integration of emotional facial expressions with their emotional context.

Negative interpersonal scenes decrease inhibitory control in healthy individuals but not in gambling disorder patients

ABSTRACTWhile impaired cognitive control and decision-making are clearly related to gambling disorder (GD), it remains unclear how they are affected by interpersonal problems as contextual cues for gambling. This study tested whether these impairments in GD are specifically present following presentations of negative interpersonal scenes. Inpatients with GD (n = 49) and healthy individuals (n = 29) performed a go/no-go and an intertemporal choice task with randomly presented pictures depicting either neutral scenes or negative interpersonal scenes related to a lack of autonomy (e.g. prison scene) or appreciation (e.g. thumb downwards). The reduction of inhibitory control in the go/no-go task after negative autonomy-related compared to neutral interpersonal scenes was significantly larger in the control compared to the GD group. Within the control group, we also found a reduction of inhibitory control after negative appreciation-related compared to neutral scenes. There were no further significant between- or within- group-effects. Unexpectedly, negative interpersonal scenes decreased inhibitory control in healthy individuals but not in GD patients that may be explained post hoc by differences in stress responses or emotion regulation in reaction to the negative scenes. The effects of interpersonal problems on gambling behaviour in GD cannot directly be explained by cue-induced impairments of inhibitory control or decision-making.

Facial Expressions in Context: Electrophysiological Correlates of the Emotional Congruency of Facial Expressions and Background Scenes.

Facial expressions can display personal emotions and indicate an individual’s intentions within a social situation. They are extremely important to the social interaction of individuals. Background scenes in which faces are perceived provide important contextual information for facial expression processing. The purpose of this study was to explore the time course of emotional congruency effects in processing faces and scenes simultaneously by recording event-related potentials (ERPs). The behavioral results found that the categorization of facial expression was faster and more accurate when the face was emotionally congruent than incongruent with the emotion displayed by the scene. In ERPs the late positive potential (LPP) amplitudes were modulated by the emotional congruency between faces and scenes. Specifically, happy faces elicited larger LPP amplitudes within positive than within negative scenes and fearful faces within negative scenes elicited larger LPP amplitudes than within positive scenes. The results did not find the scene effects on the P1 and N170 components. These findings indicate that emotional congruency effects could occur in late stages of facial expression processing, reflecting motivated attention allocation.

Disentangling brain activity related to the processing of emotional visual information and emotional arousal

Processing of emotional visual information engages cognitive functions and induces arousal. We aimed to examine the modulatory role of emotional valence on brain activations linked to the processing of visual information and those linked to arousal. Participants were scanned and their pupil size was measured while viewing negative and neutral images. The visual noise was added to the images in various proportions to parametrically manipulate the amount of visual information. Pupil size was used as an index of physiological arousal. We show that arousal induced by the negative images, as compared to the neutral ones, is primarily related to greater amygdala activity while increasing visibility of negative content to enhanced activity in the lateral occipital complex (LOC). We argue that more intense visual processing of negative scenes can occur irrespective of the level of arousal. It may suggest that higher areas of the visual stream are fine-tuned to process emotionally relevant objects. Both arousal and processing of emotional visual information modulated activity within the ventromedial prefrontal cortex (vmPFC). Overlapping activations within the vmPFC may reflect the integration of these aspects of emotional processing. Additionally, we show that emotionally-evoked pupil dilations are related to activations in the amygdala, vmPFC, and LOC.

Are there age differences in attention to emotional images following a sad mood induction? Evidence from a free-viewing eye-tracking paradigm

ABSTRACTTwo experiments examined age differences in the effect of a sad mood induction (MI) on attention to emotional images. Younger and older adults viewed sets of four images while their eye gaze was tracked throughout an 8-s presentation. Images were viewed before and after a sad MI to assess the effect of a sad mood on attention to positive and negative scenes. Younger and older adults exhibited positively biased attention after the sad MI, significantly increasing their attention to positive images, with no evidence of an age difference in either experiment. A test of participants’ recognition memory for the images indicated that the sad MI reduced memory accuracy for sad images for younger and older adults. The results suggest that heightened attention to positive images following a sad MI reflects an affect regulation strategy related to mood repair. The implications for theories of the positivity effect are discussed.

Is that disgust I see? Political ideology and biased visual attention

Considerable evidence suggests that political liberals and conservatives vary in the way they process and respond to valenced (i.e., negative versus positive) information, with conservatives generally displaying greater negativity biases than liberals. Less is known about whether liberals and conservatives differentially prioritize certain forms of negative information over others. Across two studies using eye-tracking methodology, we examined differences in visual attention to negative scenes and facial expressions based on self-reported political ideology. In Study 1, scenes rated high in fear, disgust, sadness, and neutrality were presented simultaneously. Greater endorsement of socially conservative political attitudes was associated with less attentional engagement (i.e., lower dwell time) of disgust scenes and more attentional engagement toward neutral scenes. Socially conservative political attitudes were not significantly associated with visual attention to fear or sad scenes. In Study 2, images depicting facial expressions of fear, disgust, sadness, and neutrality were presented simultaneously. Greater endorsement of socially conservative political attitudes was associated with greater attentional engagement with facial expressions depicting disgust and less attentional engagement toward neutral faces. Visual attention to fearful or sad faces was not related to social conservatism. Endorsement of economically conservative political attitudes was not consistently associated with biases in visual attention across both studies. These findings support disease-avoidance models and suggest that social conservatism may be rooted within a greater sensitivity to disgust-related information.

An investigation of potential neural correlates of intrusive retrieval of distressing memories

Background and objectivesDespite the prevalence of intrusive memories across psychological disorders, little is known about the neural networks that underpin this form of memory. This study used functional magnetic resonance imaging (fMRI) to identify neural circuits associated with the retrieval of intrusive memories. MethodsParticipants with moderate levels of anxiety (N = 30) underwent a cold pressor task to induce a physiological stress response, after which they viewed 10 neutral and 10 negative film clips. In a method designed to induce intrusive memories, participants then completed an fMRI scan in which they viewed short (2 s) depictions of neutral components from the original film clips. ResultsThere were no significant differences in activations during intrusion and non-intrusion responses. Exploratory analyses comparing intrusive responses to neutral stimuli found the insula, inferior frontal gyrus, precuneus, right cerebellum and bilateral supplementary motor area were uniquely activated during experience of intrusions (compared to the neutral cue baseline), whereas no significant activations were in response to negative scenes that did not trigger intrusions. LimitationsThis study did not compare the different neural processes implicated in intrusive and intentional emotional memories. The limited intrusions that could be elicited in the scanning environment restricted the number of trials that could be employed. ConclusionsAlthough no differences in neural activations were observed between intrusive and non-intrusive responses, the observation of precuneus involvement is consistent with models that propose that intrusive memories are impacted by the extent to which there is contextual integration of the relevant memories.

Adversity, emotion recognition, and empathic concern in high-risk youth.

Little is known about how emotion recognition and empathy jointly operate in youth growing up in contexts defined by persistent adversity. We investigated whether adversity exposure in two groups of youth was associated with reduced empathy and whether deficits in emotion recognition mediated this association. Foster, rural poor, and comparison youth from Swaziland, Africa identified emotional expressions and rated their empathic concern for characters depicted in images showing positive, ambiguous, and negative scenes. Rural and foster youth perceived greater anger and happiness in the main characters in ambiguous and negative images than did comparison youth. Rural children also perceived less sadness. Youth’s perceptions of sadness in the negative and ambiguous expressions mediated the relation between adversity and empathic concern, but only for the rural youth, who perceived less sadness, which then predicted less empathy. Findings provide new insight into processes that underlie empathic tendencies in adversity-exposed youth and highlight potential directions for interventions to increase empathy.

0246 STRESS PRIOR TO ENCODING AFFECTS RESTING STATE FUNCTIONAL CONNECTIVITY AND EMOTIONAL MEMORY RETRIEVAL FOLLOWING SLEEP

Previous work has illustrated that sleep and stress enhance long-term emotional memory. Although memory for emotionally arousing items is strengthened following stress exposure, it is unclear how consolidation-related neural processes are affected. The purpose of this project was to examine whether a psychosocial stressor administered before encoding would influence subsequent emotional memory retrieval following a night of sleep through changes in the functional coupling of the ventral medial prefrontal cortex (vmPFC) and the amygdala. Participants underwent either the Trier Social Stress Test or a control task before encoding a series of negative, positive and neutral scenes while we collected functional magnetic resonance imaging (fMRI) data. Overnight sleep was recorded using polysomnography. The following day, participants returned to the MRI to complete an incidental recognition task. Change in functional connectivity was examined by comparing the resting state fMRI scans following the stress manipulation and shortly before the recognition task. Resting state fMRI data collected shortly before the recognition task revealed that greater functional coupling between the amygdala and the vmPFC post-sleep was associated with negative memory enhancement (negative d’ minus neutral d’) in participants who underwent the psychosocial stressor, β = .51, p = .02 (n = 18). Furthermore, negative memory enhancement was associated with a greater increase in coupling between the amygdala and vmPFC from the encoding to retrieval sessions, β = .46, p = .05. The participants in the stress condition who remembered more negative scenes compared to neutral scenes showed greater functional coupling between the amygdala and the vmPFC post-sleep. These preliminary results suggest that stress prior to encoding affects consolidation-related brain networks important for emotional memory function.

Direct evaluative conditioning in brand placement: The impact of scene valence and prominence on brand placement repetition effects

AbstractWhereas previous studies investigated the affect transfer from one specific affective stimulus of the brand placement context (such as an artist or the genre) to the brand, this research study investigates the effect of the valence of various scenes in which the brand is repeatedly placed on brand attitude. Direct evaluative conditioning theory suggests that pairing a brand repeatedly with various positive (negative) stimuli positively (negatively) affects brand attitude. The results of 2 experimental studies indicate that when a brand is repeatedly and prominently placed in different affective scenes of the same valence (a series of either positive or negative scenes), the affect aroused by those scenes influences explicit and implicit brand attitudes. In addition, whereas previous research found negative effects of brand prominence on brand evaluations, this study found that prominence positively moderates the affect transfer from the valence of various scenes on brand attitude. This implies that by placing the brand in various positive scenes, prominent brand placements can have a positive effect on recall and recognition and on brand attitude, which transcends the previously declared paradox of prominent placement.

Identity Coherence in the Chronicler's Narrative: King Josiah as a Second David and a Second Saul

Among the variants in Chronicles and Samuel-Kings is the inclusion of Samuel in Josiah's narrative (2 Chr 35:18) compared to “the judges who led Israel” (2 Kgs 23:22). Samuel's appearance occurs at a major transition in the Chronicler's narrative, which links Josiah to not only David, but Saul. While there is yet to be a consensus among scholars as to why a negative death scene follows Josiah's laudable Passover, the social memory associated with Samuel adds rhetorical weight to the Chronicler's narrative.

Obscurants in Babylon

Ekaterina Ivanova's article examines two novels that break the remaining taboo against positive depictions of Christianity in Russian science fiction and fantasy, The Obscurant (Mrakobes, 1994) by Elena Khaetsaia, and Ol'ga Chigirinskaia's Heart of the Sword (Serdtse mecha, 2006). After outlining the plots and main characters, she notes the grinding negative scenes the novels include and the potential effect on readers. At the same time, Ivanova sees these novels as evidence that authors are choosing to apply the language and methods of fantastika to the most difficult moral and religious questions.

Political conservatism predicts asymmetries in emotional scene memory

Variation in political ideology has been linked to differences in attention to and processing of emotional stimuli, with stronger responses to negative versus positive stimuli (negativity bias) the more politically conservative one is. As memory is enhanced by attention, such findings predict that memory for negative versus positive stimuli should similarly be enhanced the more conservative one is. The present study tests this prediction by having participants study 120 positive, negative, and neutral scenes in preparation for a subsequent memory test. On the memory test, the same 120 scenes were presented along with 120 new scenes and participants were to respond whether a scene was old or new. Results on the memory test showed that negative scenes were more likely to be remembered than positive scenes, though, this was true only for political conservatives. That is, a larger negativity bias was found the more conservative one was. The effect was sizeable, explaining 45% of the variance across subjects in the effect of emotion. These findings demonstrate that the relationship between political ideology and asymmetries in emotion processing extend to memory and, furthermore, suggest that exploring the extent to which subject variation in interactions among emotion, attention, and memory is predicted by conservatism may provide new insights into theories of political ideology.

Preferential recruitment of the basolateral amygdala during memory encoding of negative scenes in posttraumatic stress disorder

Background: The vast majority of functional neuroimaging studies in posttraumatic stress disorder (PTSD) have examined the amygdala as a unitary structure. However, an emerging body of studies indicates that separable functions are subserved by discrete amygdala subregions. The basolateral subdivision (BLA), as compared with the centromedial amygdala (CMA), plays a unique role in learning and memory-based processes for threatening events, and alterations to the BLA have been implicated in the pathogenesis of PTSD. We assessed whether PTSD is associated with differential involvement of the BLA versus the CMA during successful encoding of emotionally charged events. Methods: Participants with PTSD (n=11) and a trauma-exposed comparison (TEC) group (n=11) viewed a series of photos that varied in valence (negative versus positive) and arousal (high versus low) while undergoing functional magnetic resonance imaging (fMRI). Subsequently, participants completed an old/new recognition memory test. Results: Using analytic methods based on probabilistic cytoarchitectonic mapping, PTSD was associated with greater activation of the BLA, as compared to the CMA, during successful encoding of negative scenes, a finding which was not observed in the TEC group. Moreover, this memory-related activity in the BLA independently predicted PTSD status. Contrary to hypotheses, there was no evidence of altered BLA activity during memory encoding of high arousing relative to low arousing scenes. Conclusions: Task-related brain activation in PTSD does not appear to be consistent across the entire amygdala. Importantly, memory-related processing of negative information in PTSD is associated with preferential recruitment of the BLA.

Deficits in low beta desynchronization reflect impaired emotional processing in schizophrenia

Empirical data from previous investigations showed that emotion processing is reflected in beta, and especially in low beta event related desynchronization (ERD) (i.e. a decrease in low beta power). While recognition of social information and emotion processing are impaired in schizophrenia, no previous study analyzed induced and evoked beta oscillations in patients with schizophrenia during emotion processing.Twenty-eight subjects with schizophrenia and twenty-seven healthy controls subjects were enrolled in the study. The two study groups did not differ in age, gender and education. Participants viewed positive, neutral and negative scenes selected from the International Affective Picture System (IAPS) while 128-channel EEG was recorded.A significantly weaker low beta ERD was detected in patients relative to controls for the negative stimulus condition in the right parieto-occipital and temporal regions. Patients with decreased beta ERD showed more prominent negative symptoms and more severe deficits in psychosocial functioning. Only in the control group stronger beta ERD was detected for the negative stimuli relative to positive and neutral stimuli in the same regions.Our major finding is that impaired emotion processing in schizophrenia is reflected in decreased low beta ERD and in the diminished differences between low beta ERD to negative and non-negative emotional stimuli. Furthermore, it was found that patients with decreased beta ERD show more prominent negative symptoms and more severe deficits in psychosocial functioning.
