Discomfort and avoidance of touch: new insights on the emotional deficits of social anxiety

Physical touch is central to the emotional intimacy that separates romantic relationships from other social contexts. In this study of 256 adults (128 heterosexual couples, mean relationship length?=?20.5 months), we examined whether individual differences in social anxiety influenced comfort with and avoidance of physical touch. Because of prior work on sex difference in touch use, touch comfort, and social anxiety symptoms and impairment, we explored sex-specific findings. We found evidence that women with greater social anxiety were less comfortable with touch and more avoidant of touch in same-sex friendships. Additionally, a woman’s social anxiety had a bigger effect on a man’s comfort with touch and avoidance of touch in the romantic relationship than a man’s social anxiety had on the woman’s endorsement of touch-related problems. These effects were uninfluenced by the length of romantic relationships. Touch is a neglected emotional experience that offers new insights into the difficulties of individuals suffering from social anxiety problems, and their romantic partners.     

Cognitive activity and risk of alzheimer's disease

Recent research suggests that frequent participation in cognitively stimulating activities may reduce risk of Alzheimer's disease in old age. We review epidemiological evidence of such an association. We then consider whether cognitive activity can account for the association between higher educational and occupational attainment and reduced risk of Alzheimer's disease. Finally, we discuss the behavioral and neurobiological mechanisms that may underlie the association between cognitive activity and risk of Alzheimer's disease.     

Interpersonal and emotional processes in generalized anxiety disorder analogues during social interaction tasks

Persons with chronic worry and generalized anxiety disorder (GAD) report maladaptive social cognitions, interpersonal behaviors, and emotional regulation. Because research has neither investigated these processes in actual social situations nor explored whether they take heterogeneous forms, the present study provides the first attempt to do so in a laboratory investigation. GAD analogue participants and nonanxious controls interacted with confederates in an unstructured collaborative story construction task and an emotional disclosure task with standardized confederate behavior. In both tasks, relative to controls, some GAD analogues highly overestimated, whereas others markedly underestimated, their negative (Hostile-Submissive) interpersonal impact on confederates. Although GAD analogues, as a group, exhibited greater sad affect during disclosures than controls, their openness during disclosures and liking by confederates varied with their level of misestimation of negative interpersonal impact. Results underscore the need to further explore interpersonal processes in chronic worriers and how they may exacerbate or maintain dysfunction.     

Simulating social interaction to address deficits of autistic spectrum disorder in children.

Autistic spectrum disorder (ASD) is diagnosed on the basis of impairment in reciprocal social interaction and language, and rigidity of behavior. This brief paper describes the development of an experimental intervention for preschool children newly diagnosed with ASD. The rationale for this intervention is the hypothesis that failure to attend to social cues in very early life, of itself, may bear a large share of responsibility for core social and communicative deficits. The intervention, therefore, uses eye-tracking to monitor and trigger rewards for attention to facial expression and direction of gaze.     

Lesion localization in acquired deficits of emotional expression and comprehension

This study investigated the relationship between intrahemispheric location of lesion and disturbances of emotional expression and comprehension. Twenty-eight right hemisphere strokes, 18 left hemisphere strokes, and 20 controls were examined on a standardized test of the expression, repetition, and comprehension of emotional prosody as well as the visual recognition of emotional situations and faces. The patients were classified into aprosodic syndromes according to the test scores. The lesions were independently traced, and overlapped for each aprosodic syndrome. The results, for lesions in either hemisphere, indicated involvement of the basal ganglia most frequently in aprosodic syndromes followed by anterior temporal lobe and insula lesions. Basal ganglia damage was also seen most frequently in patients with impaired comprehension of emotional facial expressions and situations. The anterior temporal lobe was also frequently involved in patients with such deficits. The basal ganglia emerged as a structure of particular importance in the mediation of emotional expression and comprehension.     

Empathy deficits and trait emotional intelligence in psychopathy and Machiavellianism

This study investigated the relationships between psychopathy (primary and secondary), Machiavellianism, trait emotional intelligence and empathy, using an image task that required an appropriate empathic response to the emotional displays of others (happy, sad and neutral). Results indicated that primary psychopathy and Machiavellianism were positively associated with the experience of positive affect from sad stimuli, while secondary psychopathy and Machiavellianism were positively associated with the experience of negative affect in response to neutral stimuli, and the opposite pattern was found for trait emotional intelligence. Regressional analyses demonstrated that secondary psychopathy, Machiavellianism, trait emotional intelligence and state anxiety are important predictors when stimuli are ambiguous.     

Probing the attentional control theory in social anxiety: An emotional saccade task

Volitional attentional control has been found to rely on prefrontal neuronal circuits. According to the attentional control theory of anxiety, impairment in the volitional control of attention is a prominent feature in anxiety disorders. The present study investigated this assumption in socially anxious individuals using an emotional saccade task with facial expressions (happy, angry, fearful, sad, neutral). The gaze behavior of participants was recorded during the emotional saccade task, in which participants performed either pro- or antisaccades in response to peripherally presented facial expressions. The results show that socially anxious persons have difficulties in inhibiting themselves to reflexively attend to facial expressions: They made more erratic prosaccades to all facial expressions when an antisaccade was required. Thus, these findings indicate impaired attentional control in social anxiety. Overall, the present study shows a deficit of socially anxious individuals in attentional control—for example, in inhibiting the reflexive orienting to neutral as well as to emotional facial expressions. This result may be due to a dysfunction in the prefrontal areas being involved in attentional control.     

Semantic sensitivity for prose in patients with probable alzheimer's disease

This study examined the sensitivity of patients with probable Alzheimer's Disease (AD) to the inherent semantic structure of prose. Patients and normal controls listened to prose passages and recalled the stories under immediate and delayed conditions. Subjects were also tested with a recognition format. Unlike controls and patients with mild AD, patients with severe AD were unable to differentiate high importance ideas from ideas of lower importance on free recall and recognition. These results suggest relative impairment of semantic processing at the encoding and consolidation process of memory in more advanced AD.

When the social mirror breaks: deficits in automatic, but not voluntary, mimicry of emotional facial expressions in autism

Humans, infants and adults alike, automatically mimic a variety of behaviors. Such mimicry facilitates social functioning, including establishment of interpersonal rapport and understanding of other minds. This fundamental social process may thus be impaired in disorders such as autism characterized by socio-emotional and communicative deficits. We examined automatic and voluntary mimicry of emotional facial expression among adolescents and adults with autistic spectrum disorders (ASD) and a typical sample matched on age, gender and verbal intelligence. Participants viewed pictures of happy and angry expressions while the activity over their cheek and brow muscle region was monitored with electromyography (EMG). ASD participants did not automatically mimic facial expressions whereas the typically developing participants did. However, both groups showed evidence of successful voluntary mimicry. The data suggest that autism is associated with an impairment of a basic automatic social-emotion process. Results have implications for understanding typical and atypical social cognition.     

Rigidity in social and emotional memory in the R6/2 mouse model of Huntington's disease

Four experiments were conducted to examine social and emotional memory in the R6/2 transgenic mouse model of Huntington’s disease. First, R6/2 mice were tested in a social transmission of food preference task where they had to acquire a preference for a flavoured food (acquisition) and subsequently to learn a preference for a different flavour (shifted reinforcement). R6/2 mice performed well in the acquisition trial. However, they were impaired in the shifted reinforcement trial and perseverated on the first preference learned. Second, mice were trained in an inhibitory avoidance paradigm, with either one or two footshocks delivered during the training. WT mice given one footshock showed retention levels lower than those of mice trained with two footshocks. By contrast, there was no difference in retention levels of R6/2 mice given either one or two footshocks. Third, mice were tested in an active avoidance task that paired a mild footshock with a warning light. R6/2 mice had a strong age-dependent deficit in this task. Finally, mice were tested in a conditioned taste aversion task that paired a saccharine solution with a nausea-inducing agent (LiCl). R6/2 mice displayed normal aversion, however this was not extinguished following repeated exposure to saccharine solution alone. Our data show that while R6/2 mice have functional hippocampus-based memory, they have deficits in striatum-based memory skills. Further, social and emotional memories appear to be encoded in a rigid way that is not influenced by subsequent learning or by arousal levels.     

Motivational and emotional effects of social comparison in sports

The comparison to other athletes and the resulting effects on emotion, motivation and effort investment are a natural and integral part of sports performance. The current study tested a bias toward upward comparison in athletes. Further it tested how comparison processes influence motivation (i.e., self-improvement motivation, coasting, disengagement), emotion (e.g. happiness and shame) and performance improvement as a behavioral measure of effort. Freshmen from an elite sport university volunteered to participate in an experience sampling study conducted over one semester (6 months). Contrary to our predictions, athletes did not generally compare more upward than downward, and only few subscales of the two sport-specific dispositional measures (sport-specific achievement motivation and sport orientation) predicted upward comparison. As hypothesized, upward comparison to moderately better standards was associated with greater motivation while extreme upward comparison was related to a drop in motivation and increased disengagement. Still, upward comparison during the semester significantly predicted performance at the end of the semester. Downward comparison was related to coasting motivation and lower levels of performance. Happiness decreased with upward and increased with downward comparison. The opposite was true for feelings of shame. This research emphasizes the role of the social environment in sports and how training partners depending on their inferiority or superiority can boost or hinder motivation and performance in athletes.     

Encapsulated social perception of emotional expressions

In this paper I argue that the detection of emotional expressions is, in its early stages, informationally encapsulated. I clarify and defend such a view via the appeal to data from social perception on the visual processing of faces, bodies, facial and bodily expressions. Encapsulated social perception might exist alongside processes that are cognitively penetrated, and that have to do with recognition and categorization, and play a central evolutionary function in preparing early and rapid responses to the emotional stimuli.     

The social impact of emotional tears

The question what specific functions the production of emotional tears fulfills has received only limited attention of behavioral scientists. We report the results of two studies on the social impact of emotional tears. In Study 1 (96 Dutch females), perceived helplessness and felt connectedness predicted the willingness to help a person depicted as crying tearfully, while perceived friendliness did not. In Study 2 (US sample, 128 males, 68 females) all three of these variables mediated the effect the display of tears had on the willingness to help. Our results replicate and extend previous work and add to current knowledge by showing that tearful crying facilitates helping behavior and by identifying reasons why people are more willing to help criers. These findings help to put forth novel predictions on the impact of tearful crying on others.     

Explicit vs. implicit emotional processing: The interaction between processing type and executive control

The current study examined whether the interaction between emotion and executive control (EC) is modulated by the processing type of the emotional information. Namely, whether the emotional information is explicitly processed, implicitly processed or passively viewed. In each trial, a negative or neutral picture preceded an arrow-flanker stimulus that was congruent or incongruent. Incongruent stimuli are known to recruit EC. Explicit processing of the pictures (Experiment 1a), which required responding to their emotional content, resulted in emotional interference for congruent but not for incongruent stimuli. Similar effects were shown for the passive viewing condition (Experiment 2). In contrast, implicit processing (Experiment 1b), which required responding to non-emotional content, resulted in emotional interference for both congruent and incongruent stimuli. Thus, our findings indicate that implicit emotional processing affects performance independently of EC recruitment. In contrast, explicit emotional processing and passive viewing of emotional pictures lead to reduced emotional interference when EC is recruited.     

Identity and influence in social interaction

Researchers studying argumentation often make the simplifying assumption that rational persuasion can be studied independently from the processes through which social identities are established and maintained. However, developments in the study of message design, particularly the groundbreaking work of Brown and Levinson (1978, 1987) on politeness, suggests that in practice the multiple functions of messages are intertwined in message structure and effects. In contrast to the view that identity issues distort rational processes in communication, both the communication of identity and the use of identity-based appeals in social influence are best seen as prototypical examples of rationality in message design.     

Adult attachment and emotional control

The connection between attachment style and affect regulation, proposed by attachment theorists, was explored in the context of long-term dating relationships. Seventy-two couples completed questionnaire measures of attachment (using a four-group forced-choice item, together with scales tapping Comfort with closeness, and Anxiety over relationships) and emotional control (in which subjects rated own and partner's control of anger, sadness, and anxiety, and the extent to which partners wanted them to control these emotions). Couples in which both partners endorsed insecure attachment styles (using the forced-choice measure) reported greater emotional control than did couples with two secure partners. Data from the attachment scales also supported the link between insecure attachment and emotional control: Comfort with closeness was negatively related both to one's own emotional control and to perceptions that partners wanted subjects to control their sadness; Anxiety over relationships was associated with perceptions that partners controlled sadness and wanted subjects to control their anger and sadness. The link between insecure attachment and the control of negative emotion remained significant when the frequency of experiencing such emotion was controlled. The association between attachment dimensions and other responses to negative emotions was also explored, and was consistent with attachment theory.
