The role of Need for Affect and Need for Cognition in self-evaluation

The primary aim of this study was to investigate whether individual differences in affective and cognitive orientation predict the relative importance of warmth-related and competence-related traits in self-evaluation. 99 participants (85 females) completed the Need for Affect and Need for Cognition scales. Later, participants rated the extent to which warmth- and competence-related traits described their own personality. In line with our hypotheses, affective people expressed more positive evaluations of warmth traits and more negative evaluations of cold traits relative to cognitive people, who expressed more positive evaluations of competence traits and more negative evaluations of incompetence traits. This differentiation has implications for self-evaluation processes and individual differences in affective and cognitive orientation

The role of affective and cognitive individual differences in social perception

Three studies explored the connection between social perception processes and individual differences in the use of affective and cognitive information in relation to attitudes. Study 1 revealed that individuals high in need for affect (NFA; Maio & Esses, 2001) accentuated differences in evaluations of warm and cold traits, whereas individuals high in need for cognition (NFC; Cacioppo & Petty, 1982) accentuated differences in evaluations of competent and incompetent traits. Study 2 revealed that individual differences in NFA predicted liking of warm or cold targets,whereas individual differences in NFC predicted perceptions of competent or incompetent targets. Further, the effects of NFA and NFC were independent of structural bases and meta-bases of attitudes. Study 3 revealed that differences in the evaluation of warm and cold traits mediated the effects of NFA and NFC on liking of targets. The implications for social perception processes and for individual differences in affect-cognition are discussed

Sense or sensibility? The neuro-functional basis of the structural matching effect in persuasion

The present study investigates the neural pathways underlying individual susceptibility to affective or cognitive information in persuasive communication, also known as the structural matching effect. Expanding on the presumed involvement of the ventromedial prefrontal cortex (vMPFC) in persuasion, we hypothesized that the vMPFC contributes to the evaluation of persuasive information depending on its match with the recipient’s affective or cognitive predominance. During functional magnetic resonance imaging, 30 participants evaluated 10 consumable products presented with both affective and cognitive persuasive messages. All participants were characterized on a continuum regarding their personal orientation in terms of individual differences in need for affect (NFA) and need for cognition (NFC). The results showed that the vMPFC, posterior cingulate cortex, and cerebellum are more strongly activated when the persuasive message content, either affective or cognitive, matched the recipient’s individual affective or cognitive orientation. Interestingly, this effect in the vMPFC was found specifically when participants evaluated the products presented by the persuasive messages, whereas the correlation in the posterior cingulate cortex and cerebellum activity was detected when reading the messages. These results confirm the hypothesis that the vMPFC plays a role in subjectively weighting persuasive message content depending on individual differences in affective and cognitive orientation. Such a structural matching effect might involve the vMPFC particularly during explicit expressions of subjective valuations. These novel findings also further develop the conceptualisation of the role of the vMPFC in self-related processing

Intrinsic Shapes of Empathy: Functional Brain Network Topology Encodes Intersubjective Experience and Awareness Traits

Trait empathy is an essential personality feature in the intricacy of typical social inclinations of individuals. Empathy is likely supported by multilevel neuronal network functioning, whereas local topological properties determine network integrity. In the present functional MRI study (N = 116), we aimed to trace empathic traits to the intrinsic brain network architecture. Empathy was conceived as composed of two dimensions within the concept of pre-reflective, intersubjective understanding. Vicarious experience consists of the tendency to resonate with the feelings of other individuals, whereas intuitive understanding refers to a natural awareness of others’ emotional states. Analyses of graph theoretical measures of centrality showed a relationship between the fronto-parietal network and psychometric measures of vicarious experience, whereas intuitive understanding was associated with sensorimotor and subcortical networks. Salience network regions could constitute hubs for information processing underlying both dimensions. The network properties related to empathy dimensions mainly concern inter-network information flow. Moreover, interaction effects implied several sex differences in the relationship between functional network organization and trait empathy. These results reveal that distinct intrinsic topological network features explain individual differences in separate dimensions of intersubjective understanding. The findings could help understand the impact of brain damage or stimulation through alterations of empathy-related network integrity

"The face of ostracism":The impact of the social categorization on the thermal facial responses of the target and the observer

Ostracism has been shown to elicit pain in both the target and the observers. Two experiments investigated the autonomic thermal signature associated with an ostracism experience and assessed whether and how social categorization impacts the autonomic arousal of both the target and the observer. Autonomic response was assessed using thermal infrared imaging, recording facial temperature variation during an online game of ball toss (i.e., Cyberball). Social categorization was manipulated using a minimal group paradigm. The results show a more intense autonomic response during ostracism (vs. inclusion), marked by an increase in facial temperature in the nose and the perioral area. This autonomic response is stronger when individuals are ostracized by ingroup (vs. outgroup) members. Similar pattern of temperature variations emerge when individuals observe an ostracism episode involving ingroup members. Our findings advance the understanding of psycho-physiological mechanisms underlying the ostracism experience and emphasize the impact of social categorization in such mechanisms.

Brain and behavioral contributions to individual choices in response 1 to affective-cognitive persuasion

Affective and cognitive information conveyed by persuasive stimuli is evaluated and integrated by individuals according to their behavioral predispositions. However, the neurocognitive structure that supports persuasion based on either affective or cognitive content is poorly understood. Here, we examine the neural and behavioral processes supporting choices based on affective and cognitive persuasion by integrating 4 information processing features: intrinsic brain connectivity, stimulus-evoked brain activity, intrinsic affective–cognitive orientation, and explicit target evaluations. We found that the intrinsic cross-network connections of a multimodal fronto-parietal network are associated with individual affective–cognitive orientation. Moreover, using a cross-validated classifier, we found that individuals’ intrinsic brain-behavioral dimensions, such as affective–cognitive orientation and intrinsic brain connectivity, can predict individual choices between affective and cognitive targets. Our findings show that affective- and cognitive-based choices rely on multiple sources, including behavioral orientation, stimulus evaluation, and intrinsic functional brain architecture
