Embodiment effects in memory for facial identity and facial expression

Research suggests that states of the body, such as postures, facial expressions, and arm movements, play central roles in social information processing. This study investigated the effects of approach/avoidance movements on memory for facial information. Faces displaying a happy or a sad expression were presented and participants were induced to perform either an approach (arm flexion) or an avoidance (arm extension) movement. States of awareness associated with memory for facial identity and memory for facial expression were then assessed with the Remember/Know/Guess paradigm. The results showed that performing avoidance movements increased Know responses for the identity, and Know/Guess responses for the expression, of valence-compatible stimuli (i.e., sad faces as compared to happy faces), whereas this was not the case for approach movements. Based on these findings, it is suggested that approach/avoidance motor actions influence memory encoding by increasing the ease of processing for valence-compatible information.     

On the dynamics of implicit emotion regulation: Counter-regulation after remembering events of high but not of low emotional intensity

Valence biases in attention allocation were assessed after remembering positive or negative personal events that were either still emotionally hot or to which the person had already adapted psychologically. Differences regarding the current state of psychological adjustment were manipulated experimentally by instructing participants to recall distant vs. recent events (Experiment 1) or affectively hot events vs. events to which the person had accommodated already (Experiment 2). Valence biases in affective processing were measured with a valence search task. Processes of emotional counter-regulation (i.e., attention allocation to stimuli of opposite valence to the emotional event) were elicited by remembering affectively hot events, whereas congruency effects (i.e., attention allocation to stimuli of the same valence as the emotional event) were obtained for events for which a final appraisal had already been established. The results of our study help to resolve conflicting findings from the literature regarding congruent vs. incongruent effects of remembering emotional events on affective processing. We discuss implications of our findings for the conception of emotions and for the dynamics of emotion regulation processes.     

Searching for emotion or race: Task-irrelevant facial cues have asymmetrical effects

Facial cues of threat such as anger and other race membership are detected preferentially in visual search tasks. However, it remains unclear whether these facial cues interact in visual search. If both cues equally facilitate search, a symmetrical interaction would be predicted; anger cues should facilitate detection of other race faces and cues of other race membership should facilitate detection of anger. Past research investigating this race by emotional expression interaction in categorisation tasks revealed an asymmetrical interaction. This suggests that cues of other race membership may facilitate the detection of angry faces but not vice versa. Utilising the same stimuli and procedures across two search tasks, participants were asked to search for targets defined by either race or emotional expression. Contrary to the results revealed in the categorisation paradigm, cues of anger facilitated detection of other race faces whereas differences in race did not differentially influence detection of emotion targets.     

Disequilibrium in the mind,disharmony in the body

Although it is generally acknowledged that experiences of frustration, confusion, and anxiety are embodied phenomena, very little is known about how these processes modulate presumably unconscious, but constantly present, subtle bodily movement. We addressed this problem by tracking the low-level dynamics of body movement, using 1/f noise, pink noise, or “fractal scaling”, during naturalistic experiences of affect in two studies involving deep learning and effortful problem-solving. Our results indicate that body movement fluctuations of individuals experiencing cognitive equilibrium was characteristic of correlated pink noise, but there was a whitening of the signal when participants experienced states that are diagnostic of cognitive distress such as anxiety, confusion, and frustration. We orient our findings within theories that emphasise the embodied nature of cognition and affect and with perspectives that view affective and cognitive processes as emergent products of a self-organising dynamical system (the brain) that is inextricably coupled to the body.     

The effect of facial expression and gaze direction on memory for unfamiliar faces

We report data from an experiment that investigated the influence of gaze direction and facial expression on face memory. Participants were shown a set of unfamiliar faces with either happy or angry facial expressions, which were either gazing straight ahead or had their gaze averted to one side. Memory for faces that were initially shown with angry expressions was found to be poorer when these faces had averted as opposed to direct gaze, whereas memory for individuals shown with happy faces was unaffected by gaze direction. We suggest that memory for another individual's face partly depends on an evaluation of the behavioural intention of that individual.     

The Relation Between Appraised Mismatch and the Duration of Negative Emotions: Evidence for Universality

Emotions are processes that unfold over time. As a consequence, a better understanding of emotions can be reached only when their time‐related characteristics can be assessed and interpreted adequately. A central aspect in this regard is the duration of emotional experience. Previous studies have shown that an emotional experience can last anywhere from a couple of seconds up to several hours or longer. In this article, we examine to what extent specific appraisals of the eliciting event may account for variability in emotion duration and to what degree appraisal–duration relations are universal or culture specific. Participants in 37 countries were asked to recollect emotional episodes of fear, anger, sadness, disgust, shame and guilt. Subsequently, they were asked to report the duration of these episodes and to answer a number of questions regarding their appraisal of the emotion‐eliciting event. Multi‐level analyses revealed that negative emotions last especially long when the eliciting event and its consequences are perceived to be incongruent with the individual's goals, values and self‐ideal, creating a mismatch. These relations are largely universal, although evidence for some limited variability across countries is found as well. Copyright © 2013 European Association of Personality Psychology     

Emotion Dysregulation in Comorbid Posttraumatic Stress Disorder and Substance Use Disorders: A Narrative Review

Co-occurrence of substance use disorders (SUDs) and posttraumatic stress disorder (PTSD) is extremely common and is associated with elevated dropout and relapse rates. Given that PTSD/SUD co-occurrence rates among veterans have been found to be as high as 55?75%, it is important to identify mechanisms that may affect the interplay of both disorders. Emotion dysregulation (ED) presents a candidate mechanism that may underlie poor treatment response in co-occurring PTSD/SUD. This article proposes a transdiagnostic emotion regulation framework that considers ED conceptualized as a combination of low ability to tolerate emotional distress (low distress tolerance) and difficulties in the goal-directed use of emotion regulation strategies as a key risk factor in co-occurring PTSD/SUD. The authors review empirical findings from self-report and laboratory-based studies of ED in PTSD. They describe psychological explanations of the emotion-substance relationship and review studies documenting ED in SUDs and in co-occurring PTSD/SUD. The literature on ED in PTSD/SUD suggests that (a) patients with PTSD may resort to substances to cope with trauma-related symptoms due to ED, and (b) ED may maintain SUD symptoms and interfere with psychological treatment. Longitudinal studies on bidirectional relationships between ED and substance use in PTSD are needed, particularly research examining the course of ED in PTSD patients who use substances versus those who do not.     

On Philosophy

In this article the author holds that progress in philosophy is a vague concept. Its criteria are not universally acknowledged. All that is clear is that philosophy does not develop in a linear way. Philosophy is polydiscoursive. As for the past fifty years, the author believes three important things happened in philosophy. (1) It has been shown that consciousness exists not within one individual but spreads within a community of people; (2) philosophy has discovered autism, a result that helps us to understand a human being as neither a biological nor a social individual but a third thing—a dreaming being who is not only asocial but also tongueless, where speech and consciousness are separated; and (3) contemporary philosophy has learned to distinguish between sign and symbol. And it has been realized that the human mind is neither an instinct nor a computer but an objectified suffering, a transformed emotion.     

Prospective and concurrent correlates of emotion perception in psychotic disorders: A naturalistic,longitudinal study of neurocognition,affective blunting and avolition

This naturalistic study investigated longitudinal and cross‐sectional symptomatic and neurocognitive correlates of social cognition indexed by emotion perception. Participants were 31 persons admitted to a psychiatric emergency ward due to acute psychosis. Positive and negative (i.e., affective blunting and avolition) symptoms were assessed at baseline and 12‐month follow‐up using the Positive and Negative Syndrome Scale. Participants completed neuropsychological assessments with alternative versions of the Repeatable Battery for the Assessment of Neuropsychological Status at baseline and at 12‐month follow‐up. Emotion perception was measured using the Face/Voice Emotion Test at 12‐month follow‐up. Correlational analyses (Spearman's rho) revealed strong and statistically significant associations between neurocognition and emotion perception (baseline r = 0.58, follow‐up r = 0.43). Associations between positive symptoms and emotion perception were weak or non‐existent (baseline r = 0.13, follow‐up r  =  –0.01). Emotion perception was moderately, but not significantly, associated with affective blunting at follow‐up (r = 0.33), but not at baseline (r = 0.21). The association with avolition was non‐existent (baseline r  =  –0.05, follow‐up r = 0.01). This study supports the notion that emotion perception has neurocognitive correlates. The cross‐sectional trend level association with affective blunting suggests that the ability to perceive emotions might be related to, but dissociable from the ability to express emotions.     

Cognitive deficits of executive functions and decision‐making in obsessive‐compulsive disorder

The nature of cognitive deficits in obsessive‐compulsive disorder (OCD) is characterized by contradictory findings in terms of specific neuropsychological deficits. Selective impairments have been suggested to involve visuospatial memory, set shifting, decision‐making and response inhibition. The aim of this study was to investigate cognitive deficits in decision‐making and executive functioning in OCD. It was hypothesized that the OCD patients would be less accurate in their responses compared to the healthy controls in rational decision‐making on a version of the Cambridge gambling task (CGT) and on the color‐word interference test and on a version of the Tower of Hanoi test (tower test) of executive functioning. Thirteen participants with OCD were compared to a group of healthy controls (n = 13) matched for age, gender, education and verbal IQ. Results revealed significant differences between the OCD group and the healthy control group on quality of decision‐making on the CGT and for achievement score on the tower test. On these two tasks the OCD group performed worse than the healthy control group. The symptom‐dimension analysis revealed performance differences where safety checking patients were impaired on the tower test compared to contamination patients. Results are discussed in the framework of cognition and emotion processing and findings implicate that OCD models should address, specifically, the interaction between cognition and emotion. Here the emotional disruption hypothesis is forwarded to account for the dysfunctional behaviors in OCD. Further implications regarding methodological and inhibitory factors affecting cognitive information processing are highlighted.
