Thinking extreme social violence: The model of the literary plague

The author uses literary plagues as a model for thinking psychoanalytically about the basic anxieties activated among perpetrators of sanctioned massacres. The model of the plague allows abstracting an underlying primitive psychological organization characterized by syncretism and a powerful anxiety of de-differentiation and confusion, leading characteristically to imitative behavior within the in-group as well as to the disavowal of the out-group members similarities to oneself, i.e. the disavowal of the other's humanity. Recognizing the historical and social foundations of discrimination and genocide, the author analyzes the interaction between group and individual processes that allow ordinary people to join daily acts of immoral violence. She dramatizes the model of the plague through a psychoanalytic reading of three literary plagues: Thebes' plague according to Sophocles, Camus's chronicle of the plague in Oran, and Saramago's meditation on the plague of white blindness.     

GETTING UNDER MY SKIN: WILLIAM JAMES ON THE EMOTIONS, SOCIALITY, AND TRANSCENDENCE

“You are really getting under my skin!” This exclamation suggests a series of psychological, philosophical, and metaphysical questions: What is the nature and development of human emotion? How does emotion arise in social interaction? To what extent can interactive situations shape our embodied selves and intensify particular affective states? With these questions in mind, William James begins to investigate the character of emotions and to develop a model of what he terms the social self. James's studies of mimicry and his interest in phenomena now often investigated using biofeedback begin to explain how affective states develop and how it might be possible for something to “get under one's skin.” I situate these studies in the history of psychology between the psychological schools of structuralism and behaviorism. More important, I suggest continuity between James's Psychology and recent research on mirror neurons, reentrant mapping, and emotional mimicry in the fields of clinical psychology and cognitive neuroscience. This research supports and extends James's initial claims in regard to the creation of emotions and the life of the social self. I propose that James's work in the empirical sciences should be read as a prelude to his metaphysical works that speak of a coordination between embodied selves and wider environmental situations, and his psychological studies should be read as a prelude to his reflections on spiritual transcendence.     

A dual-process account of female facial attractiveness preferences: Sexual and nonsexual routes

The current study conceptualizes facial attractiveness as a dual-process judgment, combining sexual and aesthetic value. We hypothesized that holistic face processing is more integral to perceiving aesthetic preference and feature-based processing is more integral to sexual preference. In order to manipulate holistic versus feature-based processing, we used a variation of the composite face paradigm. Previous work indicates that slightly shifting the top from the bottom half of a face disrupts holistic processing and enhances feature-based processing. In the present study, while nonsexual judgments best explained facial attraction in whole-face images, a reversal occurred for split-face images such that sexual judgments best explained facial attraction, but only for mate-relevant faces (i.e., other-sex). These findings indicate that disrupting holistic processing can decouple sexual from nonsexual judgments of facial attraction, thereby establishing the presence of a dual-process.     

Reduction of appeasement‐related affect as a concomitant of diazepam‐induced aggression: evidence for a link between aggression and the expression of self‐conscious emotions

Aggressive responding following benzodiazepine ingestion has been recorded in both experimental and client populations, however, the mechanism responsible for this outcome is unclear. The goal of this study was to identify an affective concomitant linked to diazepam‐induced aggression that might be responsible for this relationship. Thirty males (15 diazepam and 15 placebo) participated in the Taylor Aggression Paradigm while covertly being videotaped. The videotapes were analyzed using the Facial Action Coding System with the goal of identifying facial expression differences between the two groups. Relative to placebo participants, diazepam participants selected significantly higher shock settings for their opponents, consistent with past findings using this paradigm. Diazepam participants also engaged in significantly fewer appeasement expressions (associated with the self‐conscious emotions) during the task, although there were no group differences for other emotion expressions or for movements in general.

The bimodal bilingual brain: effects of sign language experience

Bimodal bilinguals are hearing individuals who know both a signed and a spoken language. Effects of bimodal bilingualism on behavior and brain organization are reviewed, and an fMRI investigation of the recognition of facial expressions by ASL-English bilinguals is reported. The fMRI results reveal separate effects of sign language and spoken language experience on activation patterns within the superior temporal sulcus. In addition, the strong left-lateralized activation for facial expression recognition previously observed for deaf signers was not observed for hearing signers. We conclude that both sign language experience and deafness can affect the neural organization for recognizing facial expressions, and we argue that bimodal bilinguals provide a unique window into the neurocognitive changes that occur with the acquisition of two languages.     

Looking at You or Looking Elsewhere: The Influence of Head Orientation on the Signal Value of Emotional Facial Expressions

The role of horizontal head tilt for the perceptions of emotional facial expressions was examined. For this, a total of 387 participants rated facial expressions of anger, fear, sadness, and happiness, as well as neutral expressions shown by two men and two women in either a direct or an averted face angle. Decoding accuracy, attributions of dominance and affiliation, emotional reactions of the perceivers, and the felt desire to approach the expresser were assessed. Head position was found to strongly influence reactions to anger and fear but less so for other emotions. Direct anger expressions were more accurately decoded, perceived as less affiliative, and elicited higher levels of anxiousness and repulsion, as well as less desire to approach than did averted anger expressions. Conversely, for fear expressions averted faces elicited more negative affect in the perceiver. These findings suggest that horizontal head position is an important cue for the assessment of threat.

Cognitive and physiological markers of emotional awareness in chimpanzees (Pan troglodytes)

The ability to understand emotion in others is one of the most important factors involved in regulating social interactions in primates. Such emotional awareness functions to coordinate activity among group members, enable the formation of long-lasting individual relationships, and facilitate the pursuit of shared interests. Despite these important evolutionary implications, comparative studies of emotional processing in humans and great apes are practically nonexistent, constituting a major gap in our understanding of the extent to which emotional awareness has played an important role in shaping human behavior and societies. This paper presents the results of two experiments that examine chimpanzees' responses to emotional stimuli. First, changes in peripheral skin temperature were measured while subjects viewed three categories of emotionally negative video scenes; conspecifics being injected with needles (INJ), darts and needles alone (DART), and conspecific directing agonism towards the veterinarians (CHASE). Second, chimpanzees were required to use facial expressions to categorize emotional video scenes, i.e., favorite food and objects and veterinarian procedures, according to their positive and negative valence. With no prior training, subjects spontaneously matched the emotional videos to conspecific facial expressions according to their shared emotional meaning, indicating that chimpanzee facial expressions are processed emotionally, as are human expressions. Decreases in peripheral skin temperature, indicative of negative sympathetic arousal, were significantly lower when subjects viewed the INJ and DART videos, compared to the CHASE videos, indicating greater negative arousal when viewing conspecifics being injected with needles, and needles themselves, than when viewing conspecifics engaged in general agonism.

Categorical and dimensional perceptions in decoding emotional facial expressions

We investigated whether categorical perception and dimensional perception can co-occur while decoding emotional facial expressions. In Experiment 1, facial continua with endpoints consisting of four basic emotions (i.e., happiness–fear and anger–disgust) were created by a morphing technique. Participants rated each facial stimulus using a categorical strategy and a dimensional strategy. The results show that the happiness–fear continuum was divided into two clusters based on valence, even when using the dimensional strategy. Moreover, the faces were arrayed in order of the physical changes within each cluster. In Experiment 2, we found a category boundary within other continua (i.e., surprise–sadness and excitement–disgust) with regard to the arousal and valence dimensions. These findings indicate that categorical perception and dimensional perception co-occurred when emotional facial expressions were rated using a dimensional strategy, suggesting a hybrid theory of categorical and dimensional accounts.     

Attending to emotional expressions: no evidence for automatic capture in the dot-probe task

Research on automatic attention to emotional faces offers mixed results. Therefore we examined validity effects for facial expressions of different emotions (compared to neutral faces) with a dot-probe paradigm in seven studies (total N?=?308). Systematic variations of type of emotion, CTI, task, cue size, and masking allow for a differentiated assessment of attentional capture by emotions and possible moderating factors. Results indicate a general absence of emotional validity effects as well as a lack of significant interactions with either of the manipulated factors, indicating that facial expressions of emotions do not capture attention in a fully automatic fashion. These findings suggest that situational and contextual factors have to be taken into account when investigating attentional capture of emotional faces.     

A smile biases the recognition of eye expressions: Configural projection from a salient mouth

A smile is visually highly salient and grabs attention automatically. We investigated how extrafoveally seen smiles influence the viewers' perception of non-happy eyes in a face. A smiling mouth appeared in composite faces with incongruent non-happy (fearful, neutral, etc.) eyes, thus producing blended expressions, or it appeared in intact faces with genuine expressions. Attention to the eye region was spatially cued while foveal vision of the mouth was blocked by gaze-contingent masking. Participants judged whether the eyes were happy or not. Results indicated that the smile biased the evaluation of the eye expression: The same non-happy eyes were more likely to be judged as happy and categorized more slowly as not happy in a face with a smiling mouth than in a face with a non-smiling mouth or with no mouth. This bias occurred when the mouth and the eyes appeared simultaneously and aligned, but also to some extent when they were misaligned and when the mouth appeared after the eyes. We conclude that the highly salient smile projects to other facial regions, thus influencing the perception of the eye expression. Projection serves spatial and temporal integration of face parts and changes.
