Facial expressions of emotions: a methodological contribution to the study of spontaneous and dynamic emotional faces

This paper addresses methodological considerations relevant to nonverbal communication of emotion research. In order to gather more information about the interpretations given to spontaneous and dynamic facial expressions, two main objectives guide the present exploratory research. The first one is to obtain naturalistic recordings of emotional expressions in realistic settings that are ‘emotional enough’. The second one is to address the issue of dynamic judgments of facial expressions of emotion, that is real-time emotional recognition. An innovative device has been created for this specific purpose. Results show that, although the social nature of the eliciting situation is minimal, the experience of some emotions is reflected on the encoders' faces while being covertly videotaped in natural conditions. Moreover, results show the utility to investigate dynamic emotional judgments of spontaneous and dynamic expressions since observers seem to be sensitive to the slightest facial expression change in making their emotional judgments. A promising paradigm is thus proposed for the study of the dynamics of real-time nonverbal emotional interaction. Copyright © 2007 John Wiley & Sons, Ltd.     

Aging and response interference across sensory modalities

Advancing age is associated with decrements in selective attention. It was recently hypothesized that age-related differences in selective attention depend on sensory modality. The goal of the present study was to investigate the role of sensory modality in age-related vulnerability to distraction, using a response interference task. To this end, 16 younger (mean age = 23.1 years) and 24 older (mean age = 65.3 years) adults performed four response interference tasks, involving all combinations of visual and auditory targets and distractors. The results showed that response interference effects differ across sensory modalities, but not across age groups. These results indicate that sensory modality plays an important role in vulnerability to distraction, but not in age-related distractibility by irrelevant spatial information.     

Why are online games so self‐involving: A social identity analysis of massively multiplayer online role‐playing games

This article investigates the ways in which players of massively multiplayer online role‐playing games (MMORPGs) internalize being a player into their self‐concept. In accordance with the social identity framework, we assume that being a player and being a member of a guild within the game can both shape the social identity of members. In two studies, we survey players inside or outside the MMORPG. Players are interviewed either at an interguild comparison level or at the more inclusive level of MMORPG players. Study 1 (n = 84) reveals favoritism for the in‐group guild in a within‐game context, and Study 2 (n = 200) shows that valuation of and identification with the in‐group are moderated by the interview context and the level of category inclusion: Inside the game, the guild is more valued and identification is emphasized. In contrast, valuation of and identification with MMORPG players is not influenced by the interview context. Together, by examining both valuation and identification processes, this research reveals that playing online games may be self‐involving because being a player, but also being a member of a guild, directly contribute to the social identity.

Written threat: Electrophysiological evidence for an attention bias to affective words in social anxiety disorder

Social anxiety disorder (SAD) is associated with heightened sensitivity to threat cues, typically represented by emotional facial expressions. To examine if this bias can be transferred to a general hypersensitivity or whether it is specific to disorder relevant cues, we investigated electrophysiological correlates of emotional word processing (alpha activity and event-related potentials) in 20 healthy participants and 20 participants with SAD. The experimental task was a silent reading of neutral, positive, physically threatening and socially threatening words (the latter were abusive swear words) while responding to a randomly presented dot. Subsequently, all participants were asked to recall as many words as possible during an unexpected recall test. Participants with SAD showed blunted sensory processing followed by a rapid processing of emotional words during early stages (early posterior negativity – EPN). At later stages, all participants showed enhanced processing of negative (physically and socially threatening) compared to neutral and positive words (N400). Moreover, at later processing stages alpha activity was increased specifically for negative words in participants with SAD but not in healthy controls. Recall of emotional words for all subjects was best for socially threatening words, followed by negative and positive words irrespective of social anxiety. The present findings indicate that SAD is associated with abnormalities in emotional word processing characterised by early hypervigilance to emotional cues followed by cognitive avoidance at later processing stages. Most importantly, the specificity of these attentional biases seems to change as a function of time with a general emotional bias at early and a more specific bias at later processing stages.     

Procedural learning: A developmental study of motor sequence learning and probabilistic classification learning in school-aged children

In this study, we investigated motor and cognitive procedural learning in typically developing children aged 8–12 years with a serial reaction time (SRT) task and a probabilistic classification learning (PCL) task. The aims were to replicate and extend the results of previous SRT studies, to investigate PCL in school-aged children, to explore the contribution of declarative knowledge to SRT and PCL performance, to explore the strategies used by children in the PCL task via a mathematical model, and to see whether performances obtained in motor and cognitive tasks correlated. The results showed similar learning effects in the three age groups in the SRT and in the first half of the PCL tasks. Participants did not develop explicit knowledge in the SRT task whereas declarative knowledge of the cue–outcome associations correlated with the performances in the second half of the PCL task, suggesting a participation of explicit knowledge after some time of exposure in PCL. An increasing proportion of the optimal strategy use with increasing age was observed in the PCL task. Finally, no correlation appeared between cognitive and motor performance. In conclusion, we extended the hypothesis of age invariance from motor to cognitive procedural learning, which had not been done previously. The ability to adopt more efficient learning strategies with age may rely on the maturation of the fronto-striatal loops. The lack of correlation between performance in the SRT task and the first part of the PCL task suggests dissociable developmental trajectories within the procedural memory system.     

On the power of autobiographical memories: from threat and challenge appraisals to actual behaviour

Autobiographical memories are a major feature of mental life in humans. However, research on the influence of autobiographical recall on actual behaviour is scarce. We predicted and found that general memories of failure and specific memories of success resulted in worse performance than general memories of success and specific memories of failure. This performance pattern was mediated by task appraisal, suggesting that autobiographical memories (of failure and success) impact performance by shaping the perception of the upcoming task. Combined with the fact that these effects occurred even when the content of autobiographical memories was unrelated to the upcoming task, the present research represents an important step forward in understanding how autobiographical recall influences actual behaviour.     

Age and active navigation effects on episodic memory: A virtual reality study

We investigated the navigation‐related age effects on learning, proactive interference semantic clustering, recognition hits, and false recognitions in a naturalistic situation using a virtual apartment‐based task. We also examined the neuropsychological correlates (executive functioning [EF] and episodic memory) of navigation‐related age effects on memory. Younger and older adults either actively navigated or passively followed the computer‐guided tour of an apartment. The results indicated that active navigation increased recognition hits compared with passive navigation, but it did not influence other memory measures (learning, proactive interference, and semantic clustering) to a similar extent in either age group. Furthermore, active navigation helped to reduce false recognitions in younger adults but increased those made by older adults. This differential effect of active navigation for younger and older adults was accounted for by EF score. Like for the subject‐performed task effects, the effects from the navigation manipulation were well accounted for by item‐specific/relational processing distinction, and they were also consistent with a source monitoring deficit in older adults.     

Adolescents’ Attachment to Parents and Peers: Links to Young Adulthood Friendship Quality

Few studies have been carried out on emerging adults’ friendships and on their developmental roots. Research suggests that in adolescence, both attachment to parents and attachment to peers play a role in future socio-emotional development. The aim of the present study was to compare attachment in these two types of relationships in adolescence according to gender and test whether they respectively predicted the perception of best friendship in early adulthood. A sample of 83 participants (49 girls) was seen in early adolescence (M?=?13.66 years, SD?=?0.64) and 7 years later (mean age?=?21.15 years, SD?=?0.83). At T1, participants completed the Inventory of Parent and Peer Attachment, which measures attachment using three subscales (communication, alienation and trust) and one global security score. At T2, they completed the McGill Friendship Questionnaire. Results show that in adolescence, boys report higher security with parents compared to peers (mainly due to better communication), unlike girls who obtain higher scores with peers. Longitudinal findings reveal that alienation in the relation with parents is what best predicts friendship quality in early adulthood. These findings underline the specific internal working models at play in socio-emotional development and the way gender differences evolve from adolescence to early adulthood.

     

Investigating the Links Between Cultural Values and Belief in Conspiracy Theories: The Key Roles of Collectivism and Masculinity

Research suggests that belief in conspiracy theories (CT) stems from basic psychological mechanisms and is linked to other belief systems (e.g., religious beliefs). While previous research has extensively examined individual and contextual variables associated with CT beliefs, it has not yet investigated the role of culture. In the current research, we tested, based on a situated cultural cognition perspective, the extent to which culture predicts CT beliefs. Using Hofstede's model of cultural values, three nation-level analyses of data from 25, 19, and 18 countries using different measures of CT beliefs (Study 1, N = 5323; Study 2a, N = 12,255; Study 2b, N = 30,994) revealed positive associations between masculinity, collectivism, and CT beliefs. A cross-sectional study among U.S. citizens (Study 3, N = 350), using individual-level measures of Hofstede's values, replicated these findings. A meta-analysis of correlations across studies corroborated the presence of positive links between CT beliefs, collectivism, r = .31, 95% CI = [.15; .47], and masculinity, r = .39, 95% CI = [.18; .59]. Our results suggest that in addition to individual differences and contextual variables, cultural factors also play an important role in shaping CT beliefs.
