Cognitive intrusions in a non-clinical population. I. Response style, subjective experience, and appraisal

The present study identified distinctive response styles to unpleasant cognitive intrusions to further understanding of intrusive phenomena similar to those observed in obsessive-compulsive disorder and other anxiety disorders. Response styles were studied among 125 university students who completed a questionnaire describing and evaluating seven cognitive intrusions and inventories of depressive, anxious, and compulsive symptoms. Almost all subjects (99%) reported intrusions and 92% included effortful strategies in response to intrusions in their repertoire. Large differences were observed in the dominant strategy used. Three distinctive dominant response styles were identified including no effortful response (26%) and two effortful styles, attentive thinking (34%), and escape/avoidance (40%). The two groups using effortful strategies were more anxious and reported more difficulty removing intrusions. The group using escape/avoidance strategies reported more sadness, worry, guilt, and disapproval than subjects reporting no effortful response. The attentive thinking group reported more varied forms and more frequently triggered intrusions then the no effortful response group. Within subject analyses support the group comparisons and showed that intrusions eliciting escape/avoidance strategies were evaluated more disapprovingly than thoughts eliciting attentive thinking. The results are discussed in terms of Salkovskis' (Behavior Research and Therapy, 27, 677–682, 1985) formulation of obsessive-compulsive disorder and Borkovec's (Journal of Consulting and Clinical Psychology, 23, 481–482, 1985) and Barlow's (Anxiety and its disorders: The nature and treatment of anxiety and panic, 1988) discussions of worry and generalized anxiety.     

Electrophysiological correlates of emotional face processing after mild traumatic brain injury in preschool children

Evidence suggests that social skills are affected by childhood mild traumatic brain injury (mTBI), but the neural and affective substrates of these difficulties are still underexplored. In particular, nothing is known about consequences on the perception of emotional facial expressions, despite its critical role in social interactions and the importance of the preschool period in the development of this ability. This study thus aimed to investigate the electrophysiological correlates of emotional facial expressions processing after early mTBI. To this end, 18 preschool children (mean age 53 ± 8 months) who sustained mTBI and 15 matched healthy controls (mean age 55 ± 11 months) were presented with pictures of faces expressing anger, happiness, or no emotion (neutral) while event-related potentials (ERP) were recorded. The main results revealed that P1 amplitude was higher for happy faces than for angry faces, and that N170 latency was shorter for emotional faces than for neutral faces in the control group only. These findings suggest that preschool children who sustain mTBI do not present the early emotional effects that are observed in healthy preschool children at visuospatial and visual expertise stages. This study provides new evidence regarding the consequences of childhood mTBI on socioemotional processing, by showing alterations of emotional facial expressions processing, an ability known to underlie social competence and appropriate social interactions.     

Are Vivid (Vs. Pallid) Threats Persuasive? Examining the Effects of Threat Vividness in Health Communications

To encourage the adoption of protective recommendations, health communications often include vivid information depicting the features of relevant threats. Despite a large body of research on threatening communications, little attention has been yet given to threat vividness. Across three experiments, we thus tested whether including a vivid (vs. pallid) threat in a health communication affects the acceptance of recommendations. Results revealed greater responses when people were exposed to a vivid threat, relative to a pallid threat. However, we also demonstrated that such beneficial effects were dependent on threat severity and vulnerability to the threat. Taken together, these findings underscore the importance of distinguishing the effects of the threat from those of its vividness.     

Electrophysiological correlates of emotional crossmodal processing in binge drinking

Emotional crossmodal integration (i.e., multisensorial decoding of emotions) is a crucial process that ensures adaptive social behaviors and responses to the environment. Recent evidence suggests that in binge drinking—an excessive alcohol consumption pattern associated with psychological and cerebral deficits—crossmodal integration is preserved at the behavioral level. Although some studies have suggested brain modifications during affective processing in binge drinking, nothing is known about the cerebral correlates of crossmodal integration. In the current study, we asked 53 university students (17 binge drinkers, 17 moderate drinkers, 19 nondrinkers) to perform an emotional crossmodal task while their behavioral and neurophysiological responses were recorded. Participants had to identify happiness and anger in three conditions (unimodal, crossmodal congruent, crossmodal incongruent) and two modalities (face and/or voice). Binge drinkers did not significantly differ from moderate drinkers and nondrinkers at the behavioral level. However, widespread cerebral modifications were found at perceptual (N100) and mainly at decisional (P3b) stages in binge drinkers, indexed by slower brain processing and stronger activity. These cerebral modifications were mostly related to anger processing and crossmodal integration. This study highlights higher electrophysiological activity in the absence of behavioral deficits, which could index a potential compensation process in binge drinkers. In line with results found in severe alcohol-use disorders, these electrophysiological findings show modified anger processing, which might have a deleterious impact on social functioning. Moreover, this study suggests impaired crossmodal integration at early stages of alcohol-related disorders.     

The effect of the two feet-in-the-door technique on tobacco deprivation

The ‘Foot-in-the-door’ (FITD) is a well-known compliance technique that increases compliance with a request. Many investigations on this paradigm have generally used prosocial requests to test the effect of the technique. A new evaluation of the effect of the FITD technique was carried out on tobacco deprivation. A two feet-in-the-door technique in which the target request was preceded by two small target requests was used to encourage students to stop smoking for 24 h. The results were compared with two single foot-in-the- door procedures in which the final request was only preceded by one small request, as well as with a control condition using only a 24 h stop-smoking request. Results showed that the single FITD and the two feet-in-the-door procedures were effective to increase verbal compliance (accepting to stop smoking) but only the two feet-in-the-door technique significantly increased behavioural compliance (not smoking for 24 h) with the request.     

The multiple neural networks of familiarity: A meta-analysis of functional imaging studies

Recent research has demonstrated the critical role of the feeling of familiarity in recognition memory. Various neuroimaging paradigms have been developed to identify the brain regions that sustain the processing of familiarity; however, there is still considerable controversy about the functional significance of each brain region implicated in familiarity-based retrieval. Here, we focused on the differences between paradigms that assess familiarity, with or without the encoding phase. We used the activation likelihood estimation (ALE) algorithm to conduct a whole-brain meta-analysis of neuroimaging studies that involved a familiarity task. Sixty-nine studies, performed in healthy subjects to determine the specific functions of the identified regions in familiarity processing, were finally selected. Distinct subanalyses were performed according to the experimental procedures used in the original studies. The ALE clusters that were highlighted revealed common activations for paradigms with and without encoding in the prefrontal cortex and in the parietal cortex. Additionally, supplementary activations related to specific familiarity (i.e., without the encoding phase) were observed in the limbic system (i.e., the amygdala, hippocampus, cingulate cortex, and insula) and in the associative sensory areas. The differences in the reported findings for different procedures are possibly due to differences in the concept of familiarity. To aid the exploration of the neural correlates of familiarity in future studies, the strengths and weaknesses of these experimental procedures are critically discussed.     

What is Evagrian ΓΝΩΣΙΣ?

Abstract: Evagrius famously characterises divine nature as γνῶσις οὐσιώδης, ‘substantial knowledge’. In the Alexandrian, Cappadocian, and other intellectual contexts informed by Platonic, Aristotelian, and Philonic thought, characterisations of God as a noetic or intellectual being are fairly common. However, these traditions concur in using the term νοῦς rather than γνῶσις. How can we explain that Evagrius deviates from the metaphysical mainstream? In this paper, I review this question from an historical and systematic point of view. I propose to examine ancient theories of Mind about the function and structure of the νοῦς, compare them to the Evagrian theory, and identify a possible explanation for the substitution of γνῶσις to the νοῦς. Since God is the key element in Evagrius's metaphysics, a clearer vision of the divine essence will help us appreciate the whole system more fully.     

How Can People Be Induced to Willingly Change Their Behavior? The Path from Persuasive Communication to Binding Communication

How can people be induced to willingly change their behavior? The present article has three main objectives. Its first purpose is to review some of the procedures pertaining to the ‘free will’ compliance paradigm. These procedures increase the likelihood that others will freely comply to one's requests (low‐ball, teasing, foot‐in‐the door, touch, and ‘you are free to’ procedures). The second objective is to introduce a theory stemming from social psychology, namely, the theory of commitment. Finally, we wish to describe the binding communication approach that can be situated at the intersection of research conducted in both the fields of communication, more specifically in the domain of persuasive communication, and the fields of commitment and free will compliance. A project carried out to encourage school children to behave in a more environmentally friendly way will be described to illustrate the approach.
