Linking personality and brain anatomy: a structural MRI approach to Reinforcement Sensitivity Theory.

Soc Cogn Affect Neurosci 2019 Feb 8. Epub 2019 Feb 8.

Neuropsychology and Functional Neuroimaging, Jaume I University, Castellón, Spain.

Reinforcement Sensitivity Theory (RST) proposes a widely used taxonomy of human personality linked to individual differences at both behavioral and neuropsychological levels that describe a predisposition to psychopathology. However, the body of RST research was based on animal findings, and little is known about their anatomical correspondence in humans. Here we set out to investigate MRI structural correlates (i.

Soc Cogn Affect Neurosci 2019 Feb 8. Epub 2019 Feb 8.

Shanghai Key Laboratory of Brain Functional Genomics, School of Psychology and Cognitive Science, East China Normal University, Shanghai, China.

This study aimed to investigate the situation in which interpersonal brain synchronization (IBS) occurs during a collaborative task and examined its trajectory over time by developing a novel functional near-infrared spectroscopy (fNIRS)-based hyperscanning paradigm. Participants were asked to perform a collaborative task in three-person groups where two of the members are real participants and one is a confederate. Compared to dyads between real participants and confederates, real-participant pairings showed greater cooperation behavior and IBS between bilateral dorsolateral prefrontal cortex (DLPFC).

Magnocellular and parvocellular pathway contributions to facial threat cue processing.

Soc Cogn Affect Neurosci 2019 Feb 5. Epub 2019 Feb 5.

Athinoula A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Charlestown, MA.

Human faces evolved to signal emotions, with their meaning contextualized by eye gaze. For instance, a fearful expression paired with averted gaze clearly signals both presence of threat and its probable location. Conversely, direct gaze paired with facial fear leaves the source of the fear-evoking threat ambiguous. Read More

Soc Cogn Affect Neurosci 2019 Feb 1. Epub 2019 Feb 1.

Faculty of Health, Institute of Health and Biomedical Innovation, Queensland University of Technology, Brisbane, Australia.

Every language has words deemed to be socially inappropriate or "taboo" to utter. Taboo word production appears prominently in language disorders following brain injury. Yet, we know little about the cognitive and neural mechanisms involved in processing taboo compared to neutral language. Read More

Neural correlates of social well-being: Gray matter density in the orbitofrontal cortex predicts social well-being in emerging adulthood.

Soc Cogn Affect Neurosci 2019 Feb 1. Epub 2019 Feb 1.

School of Psychology, Shaanxi Normal University, China.

Social well-being reflects the perception of one's social functioning, which plays an important role in physical and psychological health. However, the exact neuroanatomical substrate for social well-being remains unclear. To address the issue, we employed the voxel-based morphometry (VBM) method to probe the neuroanatomical basis of individual variation in social well-being in young healthy adults (n =136). Read More

Theta resting EEG in the right TPJ is associated with individual differences in implicit intergroup bias.

Soc Cogn Affect Neurosci 2019 Jan 25. Epub 2019 Jan 25.

Institute of Psychology, Department of Social Psychology and Social Neuroscience, University of Bern, Bern, Switzerland.

Why are some people more biased than others in their implicit evaluations during social interaction? The dispositional determinants of individual differences in implicit intergroup bias are poorly understood. Here, we explored whether such variability might be explained by stable neural traits. For that purpose, we used the source-localized resting electroencephalograms of 83 members of naturalistic social groups to explain their bias in an in-/outgroup implicit association test. Read More

Differential modulation of cognitive control networks by monetary reward and punishment.

Soc Cogn Affect Neurosci 2019 Jan 28. Epub 2019 Jan 28.

Zurich Center for Neuroeconomics, Department of Economics, University of Zurich, Blümlisalpstrasse 10, CH-8006 Zürich, Switzerland.

Incentives are primary determinants of if and how well an organism will perform a given behaviour. Here, we examined how incentive valence and magnitude influence task switching, a critical cognitive control process, and test the predictions that the anterior cingulate cortex (ACC) and the ventral striatum (vStr) function as key nodes linking motivation and control systems in the brain. Our results indicate that reward and punishment incentives have both common and distinct effects on cognitive control at the behavioural and neurobiological levels. Read More

Functions of the right DLPFC and right TPJ in proposers and responders in the ultimatum game.

Soc Cogn Affect Neurosci 2019 Jan 28. Epub 2019 Jan 28.

University of Salzburg.

Recent studies explored a network of brain regions involved in economic decision making. The present study focusses on two of those regions, each relevant for specific and distinct functions in economic decision making: the right temporo-parietal junction (rTPJ) and the right dorsolateral prefrontal cortex (rDLPFC). In two experiments using transcranial direct current stimulation, we explored two proposed functions of these areas in bargaining situations using the ultimatum game: understanding the others perspective and integration of fairness norms.

Dissecting social interaction: Dual-fMRI reveals patterns of interpersonal brain-behaviour relationships that dissociate among dimensions of social exchange.

Soc Cogn Affect Neurosci 2019 Jan 15. Epub 2019 Jan 15.

Behavioural and Social Neuroscience Research Group, CEITEC - Central European Institute of Technology, Masaryk University, Kamenice 5, Brno, 62500, Czech Republic.

During social interactions, each individual's actions are simultaneously a consequence of and an antecedent to their interaction partner's behaviour. Capturing online the brain processes underlying such mutual dependency requires simultaneous measurements of all interactants' brains during real-world exchange ("hyperscanning"). This demands a precise characterisation of the type of interaction under investigation, however, and analytical techniques capable of capturing interpersonal dependencies. Read More

SAMBA - SpAtial, Motor and Bodily Awareness research group, Department of Psychology, University of Turin, Via Po 14, 10123 Turin, Italy.

Despite the fact that any successful achievement of willed actions necessarily entails the sense of body ownership (the feeling of owning the moving body parts), it is still unclear how this happens. To address this issue at both behavioral and neural level, we capitalized on sensory attenuation phenomenon (a self-generated stimulus is perceived as less intense than an identical externally-generated stimulus). We compared the intensity of somatosensory stimuli produced by one's own intended movements and by movements of an embodied fake hand. Read More

The neural development of prosocial behavior from childhood to adolescence.

Soc Cogn Affect Neurosci 2019 Jan 3. Epub 2019 Jan 3.

Department of Psychology and Neuroscience, University of North Carolina, Chapel Hill 235 E. Cameron Avenue Chapel Hill, NC 27599-3270, USA.

The transition from childhood to adolescence is marked by increasingly sophisticated social cognitive abilities that are paralleled by significant functional maturation of the brain. However, the role of social and neurobiological development in facilitating age differences in prosocial behavior remains unclear. Using a cross-sectional sample of children and adolescents (n = 51; 8-16 years), we examined the age-related correlates of prosocial behavior. Read More

A key role for stimulus-specific updating of the sensory cortices in the learning of stimulus-reward associations.

Soc Cogn Affect Neurosci 2018 Dec 20. Epub 2018 Dec 20.

Center for Cognitive Neuroscience, Duke University, Durham, NC 27708, United States.

Successful adaptive behavior requires the learning of associations between stimulus-specific choices and rewarding outcomes. Most research on the mechanisms underlying such processes has focused on subcortical reward-processing regions, in conjunction with frontal circuits. Given the extensive stimulus-specific coding in the sensory cortices, we hypothesized they would play a key role in the learning of stimulus-specific reward associations. Read More

Neurobiological responses in the adolescent striatum to being 'tested'.

Soc Cogn Affect Neurosci 2019 Jan;14(1):3-12

Department of Psychology, University of California, Los Angeles, 1285 Franz Hall, PO Box 951563, Los Angeles, CA, USA.

While emerging research implicates the striatum in adolescents' ability to learn from feedback, little is known about how motivational contexts, such as emphasizing the evaluative nature of learning tasks, modulate adolescents' striatal learning. We used functional magnetic resonance imaging during a feedback-based learning task, in conjunction with a within-subject evaluative threat manipulation, to determine whether evaluation threat influences behavioral and neural responses to feedback in adolescents. On average, adolescents were less sensitive than adults to the evaluation threat. Read More

Ongoing Monitoring of Mindwandering in Avoidant Grief Through Cortico-Basal-Ganglia Interactions.

Soc Cogn Affect Neurosci 2018 Dec 6. Epub 2018 Dec 6.

Department of Biomedical Engineering, Columbia University, New York, NY.

An avoidant grief style is marked by repeated and often unsuccessful attempts to prevent thinking about loss. Prior work shows avoidant grief involves monitoring the external environment in order to avoid reminders of the loss. Here we sought to determine whether avoidant grievers also monitor the internal environment in attempts to minimize conscious awareness of loss-related thoughts. Read More

Reward improves response inhibition by enhancing attentional capture.

Soc Cogn Affect Neurosci 2019 Jan;14(1):35-45

Key Laboratory of Cognition and Personality of Ministry of Education, Faculty of Psychology, Southwest University, Chongqing, China.

Reward plays a crucial role in enhancing response inhibition. While it is generally assumed that the process of response inhibition involves attentional capture and the stopping of action, it is unclear whether this reflects a direct impact of reward on response inhibition or rather an indirect mediation via attentional capture. Here, we employed a revised stop-signal task (SST) that separated these two cognitive elements, by including a continue signal that required the same motor response as in go trials, but also attention to a cue, as in stop trials.

Transcranial stimulation over right inferior frontal gyrus increases the weight given to private information during sequential decision-making.

Soc Cogn Affect Neurosci 2019 Jan;14(1):59-71

International Business School, Tianjin University of Finance and Economics, Tianjin, China.

Decision makers often follow other similarly situated people in making decisions, creating a sequential decision-making context. Although rational behavior is often to make the same choice as previous decision makers, which can result in an information cascade, people may assign inappropriately higher weight to their own private information and discount public information about predecessors' choices. Recent findings suggest that overweighting private information may be associated with increased activities in the inferior frontal gyrus (IFG). Read More

Increased functional coupling of the left amygdala and medial prefrontal cortex during the perception of communicative point-light stimuli.

Soc Cogn Affect Neurosci 2019 Jan;14(1):97-107

Independent Max Planck Research Group for Social Neuroscience, Max Planck Institute of Psychiatry, Munich, Germany.

Interpersonal predictive coding (IPPC) describes the behavioral phenomenon whereby seeing a communicative rather than an individual action helps to discern a masked second agent. As little is known, yet, about the neural correlates of IPPC, we conducted a functional magnetic resonance imaging study in a group of 27 healthy participants using point-light displays of moving agents embedded in distractors. We discovered that seeing communicative compared to individual actions was associated with higher activation of right superior frontal gyrus, whereas the reversed contrast elicited increased neural activation in an action observation network that was activated during all trials.

Reappraisal of incentives ameliorates choking under pressure and is correlated with changes in the neural representations of incentives.

Soc Cogn Affect Neurosci 2019 Jan;14(1):13-22

Computation and Neural Systems, California Institute of Technology, Pasadena, CA, USA.

It has been observed that the performing for high stakes can, paradoxically, lead to uncharacteristically poor performance. Here we investigate a novel approach to attenuating such 'choking under pressure' by instructing participants performing a demanding motor task that rewards successful performance with a monetary gain, to reappraise this incentive as a monetary loss for unsuccessful performance. We show that when participants applied this simple strategy, choking was significantly reduced. Read More

Behavioral and functional connectivity basis for peer-influenced bystander participation in bullying.

Soc Cogn Affect Neurosci 2019 Jan;14(1):23-33

Center for Information and Neural Networks, NICT, Suita, Osaka, Japan.

Recent studies have shown that the reactions of bystanders who witness bullying significantly affect whether the bullying persists. However, the underlying behavioral and neural mechanisms that determine a peer-influenced bystander's participation in bullying remain largely unknown. Here, we designed a new 'catch-ball' task where four players choose to throw a sequence of normal or strong (aggressive) balls in turn and examined whether the players (n = 43) participated in other players' bullying.

Confidence of emotion expression recognition recruits brain regions outside the face perception network.

Soc Cogn Affect Neurosci 2019 Jan;14(1):81-95

Department of Neuroscience, Faculty of Medicine, University of Geneva, Switzerland.

Metacognitive beliefs about emotions expressed by others are crucial to social life, yet very little studied. To what extent does our confidence in emotion expression recognition depend on perceptual or other non-perceptual information? We obtained behavioral and magnetic resonance imaging measures while participants judged either the emotion in ambiguous faces or the size of two lines flanking these faces, and then rated their confidence on decision accuracy. Distinct behavioral and neural mechanisms were identified for confidence and perceptual decision in both tasks. Read More

Neural evidence for persistent attentional bias to threats in patients with social anxiety disorder.

Soc Cogn Affect Neurosci 2018 Dec;13(12):1327-1336

Department of Psychiatry, Seoul National University Hospital, Seoul, Republic of Korea.

Does the biased attention toward social threats dwells on or disappears in patients with social anxiety disorder (SAD)? We investigated the neural mechanism of attentional bias in terms of attentional capture and holding in SAD. A total of 31 SAD patients and 30 healthy controls performed a continuous performance task detecting the orientation of a red letter 'T' while angry or neutral face distractors appeared or disappeared at the center of the screen. Behaviorally, typical attentional capture effects were found in response to abruptly appearing distractors in both groups. Read More

Early spatial attention deployment toward and away from aggressive voices.

Soc Cogn Affect Neurosci 2019 Jan;14(1):73-80

Faculté de Psychologie et des Sciences de l'Education, University of Geneva, Geneva, Switzerland.

Salient vocalizations, especially aggressive voices, are believed to attract attention due to an automatic threat detection system. However, studies assessing the temporal dynamics of auditory spatial attention to aggressive voices are missing. Using event-related potential markers of auditory spatial attention (N2ac and LPCpc), we show that attentional processing of threatening vocal signals is enhanced at two different stages of auditory processing.

Contextual valence modulates the effect of choice on incentive processing.

Soc Cogn Affect Neurosci 2018 Dec;13(12):1249-1258

Department of Psychology, Dalian Medical University, Dalian, China.

Previous research has demonstrated that reward-related neural activity is enhanced for choice relative to no-choice opportunities in the gain context. The current event-related potential study examined whether this modulatory effect of choice can be observed in both the gain and the loss contexts across anticipatory and consummatory phases of incentive processing. Thirty-two participants performed a simple choice task during which choices were made either by themselves (a choice condition) or by a computer (a no-choice condition) during a gain context (gain vs nongain) and a loss context (nonloss vs loss).

Lasting connectivity increase and anxiety reduction via transcranial alternating current stimulation.

Soc Cogn Affect Neurosci 2018 Dec;13(12):1305-1316

Department of Psychology, Florida State University, Tallahassee, FL, USA.

Growing evidence of transcranial alternating current stimulation (tACS) modulating intrinsic neural oscillations has spawned interest in applying tACS to treat psychiatric disorders associated with aberrant neural oscillations. The alpha rhythmic activity is known to dominate neural oscillations at the awake, restful state, while attenuated resting-state alpha activity has been implicated in anxious mood. Administering repeated alpha-frequency tACS (α-tACS; at individual peak alpha frequency; 8-12 Hz) over four consecutive days (in the experiment group, sham stimulation in the control group), we demonstrated immediate and lasting (>24 h) increases in resting-state posterior ➔frontal connectivity in the alpha frequency, quantified by Granger causality.

Acetaminophen has been shown to influence cognitive and affective behavior possibly via alterations in serotonin function. This study builds upon this previous work by examining the relationship between acetaminophen and dual-learning systems, comprising reflective (rule-based) and reflexive (information-integration) processing. In a double-blind, placebo-controlled study, a sample of community-recruited adults (N = 87) were randomly administered acetaminophen (1000 mg) or placebo and then completed reflective-optimal and reflexive-optimal category learning tasks.

Social comparison modulates the neural responses to regret and subsequent risk-taking behavior.

Soc Cogn Affect Neurosci 2018 10;13(10):1059-1070

Shanghai Key Laboratory of Magnetic Resonance, School of Physics and Materials Science, East China Normal University, Shanghai, China.

The current functional magnetic resonance imaging fMRI study investigated how outcomes achieved by others affect subjective regret and subsequent behavior. During the task, participants were asked to open a series of boxes consecutively until they decided to stop. Each box contained a reward (gold), except for one that contained an adverse stimulus (devil), which caused the participants to lose all the gold they collected in that trial. Read More

Neural measures of the causal role of observers' facial mimicry on visual working memory for facial expressions.

Soc Cogn Affect Neurosci 2018 Dec;13(12):1281-1291

School of Psychological Science, Tel Aviv University, Tel Aviv, Israel.

Simulation models of facial expressions propose that sensorimotor regions may increase the clarity of facial expressions representations in extrastriate areas. We monitored the event-related potential marker of visual working memory (VWM) representations, namely the sustained posterior contralateral negativity (SPCN), also termed contralateral delay activity, while participants performed a change detection task including to-be-memorized faces with different intensities of anger. In one condition participants could freely use their facial mimicry during the encoding/VWM maintenance of the faces while in a different condition participants had their facial mimicry blocked by a gel.

Dissociable processing of emotional and neutral body movements revealed by μ-alpha and beta rhythms.

Soc Cogn Affect Neurosci 2018 Dec;13(12):1269-1279

Department of Psychology, Claremont McKenna College, Claremont, CA, USA.

Both when actions are executed and observed, electroencephalography (EEG) has shown reduced alpha-band (8-12 Hz) oscillations over sensorimotor cortex. This 'μ-alpha' suppression is thought to reflect mental simulation of action, which has been argued to support internal representation of others' emotional states. Despite the proposed role of simulation in emotion perception, little is known about the effect of emotional content on μ-suppression. Read More

Praising others differently: neuroanatomical correlates to individual differences in trait gratitude and elevation.

Soc Cogn Affect Neurosci 2018 Dec;13(12):1225-1234

Department of Psychology, University of Bath, Bath, UK.

Differing from basic emotions such as happiness, gratitude and elevation are important other-praising emotions. Previous behavioral studies have established that these complex emotions differ from each other; however, it remains under-investigated whether proneness to these emotions have common or distinct neuroanatomical correlates. Here we used voxel-based morphometry to identify the common and distinct neuroanatomical correlates of trait (i. Read More

Temporal dynamics of spontaneous default-mode network activity mediate the association between reappraisal and depression.

Soc Cogn Affect Neurosci 2018 Dec;13(12):1235-1247

The Laboratory for Affect Cognition and Regulation (ACRLAB), Key Laboratory of Cognition and Personality of Ministry of Education (SWU), Faculty of Psychology, Southwest University, Chongqing, China.

Cognitive reappraisal is associated with major depressive disorder (MDD), while spontaneous activity patterns of the default mode network (DMN) is implicated in reappraisal and MDD. However, neural mechanisms subserving the close association of spontaneous reappraisal and depression are unclear. Spontaneous reappraisal, depression and resting-state functional magnetic resonance imaging (rsfMRI) were measured from 105 healthy subjects. Read More

Past-year relational victimization is associated with a blunted neural response to rewards in emerging adults.

Soc Cogn Affect Neurosci 2018 Dec;13(12):1259-1267

Department of Psychology, McGill University, Montreal, QC, Canada.

Anhedonia is associated with multiple forms of psychopathology, yet relatively, little is known about how anhedonia develops. Emerging evidence suggests that anhedonia is the result of interactions between life stress and the brain's reward systems, and that social stress, in particular, may drive these processes. One potent form of social stress is peer victimization, but very little research has focused on peer victimization beyond adolescence, and even less has examined the associations between peer victimization and neural response to rewards.

Impact of induced anxiety on neural responses to monetary incentives.

Soc Cogn Affect Neurosci 2018 Nov;13(11):1111-1119

Section on the Neurobiology of Fear & Anxiety, National Institute of Mental Health, Bethesda, MD, USA.

Previous research demonstrates that aversive stimuli can interrupt appetitive processing and that brain regions involved with the processing of potential rewards, such as the ventral striatum (VS), also respond to threatening information. Potential losses can likewise activate the VS and, thus, the full extent to which threat can impact neural responses during incentive processing remains unclear. Here, unpredictable threat of shock was used to induce anxiety while participants performed the monetary incentive delay (MID) task during functional magnetic resonance imaging (fMRI). Read More

Cognitive control and network disruption in remitted depression: a correlate of childhood adversity.

Soc Cogn Affect Neurosci 2018 10;13(10):1081-1090

Department of Psychiatry, University of Illinois at Chicago, Chicago, IL, USA.

Individuals in a major depressive episode often display impairment in cognitive control, and this impairment exists outside of the acute phase of illness. Impairment in cognitive control also has been associated with exposure to childhood adversity (CA). The current study examined whether exposure to CA can explain variance in a component of cognitive control-inhibitory control-independent of diagnostic status in young adults with and without a history of depression.

Early maternal care may counteract familial liability for psychopathology in the reward circuitry.

Soc Cogn Affect Neurosci 2018 Nov;13(11):1191-1201

Department of Child and Adolescent Psychiatry and Psychotherapy, Central Institute of Mental Health, Medical Faculty Mannheim / Heidelberg University, J5, Mannheim, Germany.

Reward processing is altered in various psychopathologies and has been shown to be susceptible to genetic and environmental influences. Here, we examined whether maternal care may buffer familial risk for psychiatric disorders in terms of reward processing. Functional magnetic resonance imaging during a monetary incentive delay task was acquired in participants of an epidemiological cohort study followed since birth (N = 172, 25 years). Read More

DNA methylation of OXTR is associated with parasympathetic nervous system activity and amygdala morphology.

Soc Cogn Affect Neurosci 2018 Nov;13(11):1155-1162

University of Virginia, Department of Psychology.

Oxytocin has anxiolytic properties whose mechanisms of action are still being identified. DNA methylation in the promoter region of the oxytocin receptor gene (OXTR), an epigenetic modification that putatively reflects a downtuning of the oxytocin system, has previously been implicated in the regulation of fear-related responses through the amygdala. In this study, we attempted to characterize the relationship between methylation of OXTR and anxiogenesis using two distinct endophenotypes: autonomic nervous system activity and subcortical brain structure.

Capacity for upregulation of emotional processing in psychopathy: all you have to do is ask.

Soc Cogn Affect Neurosci 2018 Nov;13(11):1163-1176

University of Ontario Institute of Technology, Forensic Psychology Program, 2000 Simcoe St. N, Oshawa, ON, Canada.

Historically, psychopathic individuals have been described as suffering a chronic hyporesponsivity to negatively valent stimuli. However, while a wide body of empirical work indicates that the psychopath does not manifest normal reactivity to emotional stimuli, it does not similarly indicate that they cannot do so. To attempt to differentiate these alternatives, the current functional magnetic resonance imaging (fMRI) study evaluated the extent to which offenders with varying PCL-R scores could up- (or down-) regulate their neural response to negatively valent stimuli.

Early identity recognition of familiar faces is not dependent on holistic processing.

Soc Cogn Affect Neurosci 2018 10;13(10):1019-1027

Department of Neuroscience, Kenyon College, Gambier, OH, USA.

It is widely accepted that holistic processing is critical for early face recognition, but recent work has suggested a larger role for feature-based processing. The earliest step in familiar face recognition is thought to be matching a perceptual representation of a familiar face to a stored representation of that face, which is thought to be indexed by the N250r event-related potential (ERP). In the current face-priming studies, we investigated whether this perceptual representation can be effectively activated by feature-based processing. Read More
