TL;DR: In this article, the authors developed and tested the effectiveness of a new and comprehensive set of emotional film excerpts and found that the film clips were effective with regard to several criteria such as emotional discreteness, arousal, positive and negative affect.
Abstract: Using emotional film clips is one of the most popular and effective methods of emotion elicitation. The main goal of the present study was to develop and test the effectiveness of a new and comprehensive set of emotional film excerpts. Fifty film experts were asked to remember specific film scenes that elicited fear, anger, sadness, disgust, amusement, tenderness, as well as emotionally neutral scenes. For each emotion, the 10 most frequently mentioned scenes were selected and cut into film clips. Next, 364 participants viewed the film clips in individual laboratory sessions and rated each film on multiple dimensions. Results showed that the film clips were effective with regard to several criteria such as emotional discreteness, arousal, positive and negative affect. Finally, ranking scores were computed for 24 classification criteria: Subjective arousal, positive and negative affect (derived from the PANAS; Watson & Tellegen, 1988), a positive and a negative affect scores derived from the Differential Emotions Scale (DES; Izard et al., 1974), six emotional discreteness scores (for anger, disgust, sadness, fear, amusement and tenderness), and 15 “mixed feelings” scores assessing the effectiveness of each film excerpt to produce blends of specific emotions. In addition, a number of emotionally neutral film clips were also validated. The database and editing instructions to construct the film clips have been made freely available in a website.

TL;DR: In this paper, the authors compare alternative factorial structures of the French-Canadian version of the Positive and Negative Affect Schedule (PANAS) across samples of athletes at different stages of a sport competition.
Abstract: The objective of the present study was to compare alternative factorial structures of the French-Canadian version of the Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988) across samples of athletes at different stages of a sport competition. The first sample (N = 305) was used to assess, compare, and improve the measurement model of the PANAS. The second sample (N = 217) was used to cross-validate the model that provided the best fit with the calibration sample. Results of confirmatory factor analyses suggested that a modified three-factor model with cross-loadings provided a better fit to the data than either the hypothesized or the modified two-factor models. This model was partially replicated on the second sample. Results of a multiple-group confirmatory factor analysis have shown that the model was partially invariant across the two samples.

TL;DR: In this article, the authors investigated the relationship of self-efficacy to the frequency and difficulty of high and medium risk rock climbing behaviors and found that those high in selfefficacy were more likely to participate more frequently, take calculated additional risks and attempt harder climbs when they feel confident in their abilities.

TL;DR: The psychological states preceding elite climbing competition appeared to be an important factor in determining success, even when differences in baseline ability were taken into account.
Abstract: The purpose of the present study was to assess the relationship between pre-performance psychological states and expert performance in non-traditional sport competition. Nineteen elite male sport climbers (M=24.6, SD=4.0 years of age) completed the Competitive State Anxiety Inventory-2 and the Positive and Negative Affect Schedule before an international rock climbing competition. Climbing performances were video-recorded to calculate movement fluency (entropy) and obtain ascent times. Official route scores were also obtained. Successful climbers reported higher pre-performance levels of somatic anxiety and climbed the most difficult part of the route more slowly than their unsuccessful counterparts. The psychological states preceding elite climbing competition appeared to be an important factor in determining success, even when differences in baseline ability were taken into account.

TL;DR: The recently proposed consensus definitions of PJI and approaches to accurate diagnosis are reviewed in detail and an overview of the treatment and prevention of this challenging condition is provided.
Abstract: Prosthetic joint infection (PJI) is a tremendous burden for individual patients as well as the global health care industry. While a small minority of joint arthroplasties will become infected, appropriate recognition and management are critical to preserve or restore adequate function and prevent excess morbidity. In this review, we describe the reported risk factors for and clinical manifestations of PJI. We discuss the pathogenesis of PJI and the numerous microorganisms that can cause this devastating infection. The recently proposed consensus definitions of PJI and approaches to accurate diagnosis are reviewed in detail. An overview of the treatment and prevention of this challenging condition is provided.

TL;DR: Results show the potential uses of the recorded modalities and the significance of the emotion elicitation protocol and single modality and modality fusion results for both emotion recognition and implicit tagging experiments are reported.
Abstract: MAHNOB-HCI is a multimodal database recorded in response to affective stimuli with the goal of emotion recognition and implicit tagging research. A multimodal setup was arranged for synchronized recording of face videos, audio signals, eye gaze data, and peripheral/central nervous system physiological signals. Twenty-seven participants from both genders and different cultural backgrounds participated in two experiments. In the first experiment, they watched 20 emotional videos and self-reported their felt emotions using arousal, valence, dominance, and predictability as well as emotional keywords. In the second experiment, short videos and images were shown once without any tag and then with correct or incorrect tags. Agreement or disagreement with the displayed tags was assessed by the participants. The recorded videos and bodily responses were segmented and stored in a database. The database is made available to the academic community via a web-based system. The collected data were analyzed and single modality and modality fusion results for both emotion recognition and implicit tagging experiments are reported. These results show the potential uses of the recorded modalities and the significance of the emotion elicitation protocol.

TL;DR: The experiment results show that neural signatures associated with different emotions do exist and they share commonality across sessions and individuals, and the performance of deep models with shallow models is compared.
Abstract: To investigate critical frequency bands and channels, this paper introduces deep belief networks (DBNs) to constructing EEG-based emotion recognition models for three emotions: positive, neutral and negative. We develop an EEG dataset acquired from 15 subjects. Each subject performs the experiments twice at the interval of a few days. DBNs are trained with differential entropy features extracted from multichannel EEG data. We examine the weights of the trained DBNs and investigate the critical frequency bands and channels. Four different profiles of 4, 6, 9, and 12 channels are selected. The recognition accuracies of these four profiles are relatively stable with the best accuracy of 86.65%, which is even better than that of the original 62 channels. The critical frequency bands and channels determined by using the weights of trained DBNs are consistent with the existing observations. In addition, our experiment results show that neural signatures associated with different emotions do exist and they share commonality across sessions and individuals. We compare the performance of deep models with shallow models. The average accuracies of DBN, SVM, LR, and KNN are 86.08%, 83.99%, 82.70%, and 72.60%, respectively.

TL;DR: A heuristic individual differences framework is proposed and research on three sequential components of flexibility for which propensities and abilities vary are reviewed: sensitivity to context, availability of a diverse repertoire of regulatory strategies, and responsiveness to feedback.
Abstract: People respond to stressful events in different ways, depending on the event and on the regulatory strategies they choose. Coping and emotion regulation theorists have proposed dynamic models in which these two factors, the person and the situation, interact over time to inform adaptation. In practice, however, researchers have tended to assume that particular regulatory strategies are consistently beneficial or maladaptive. We label this assumption the fallacy of uniform efficacy and contrast it with findings from a number of related literatures that have suggested the emergence of a broader but as yet poorly defined construct that we refer to as regulatory flexibility. In this review, we articulate this broader construct and define both its features and limitations. Specifically, we propose a heuristic individual differences framework and review research on three sequential components of flexibility for which propensities and abilities vary: sensitivity to context, availability of a diverse repertoire of regulatory strategies, and responsiveness to feedback. We consider the methodological limitations of research on each component, review questions that future research on flexibility might address, and consider how the components might relate to each other and to broader conceptualizations about stability and change across persons and situations.
