On Strong Attitudes and Group Deliberation: Relationships,Structure, Changes,and Effects

Drawing on quasi‐experimental data from participants in structured and moderated deliberations on sexual minority rights in Poland, this study tests the relationship between attitude importance, certainty, intensity, and extremity. This study also examines the antecedents of these attributes and their consequences for several democratically important outcomes (i.e., perceived disagreement, negative affect, attitude polarization, self‐reported polarization, argument repertoire, and political participation). This study further asks whether these attributes exert different effects than a composite attitude strength index. Although factor analysis suggests that these attributes represent one construct, they are differently affected by deliberation and exert differential effects. The analyses further reveal that relying on the composite index obscures substantial information and inaccurately represents strength‐related processes and functions. Theoretical, methodological, and practical implications are discussed.     

An intelligent facial expression recognition system with emotion intensity classification

Facial expressions play a crucial role in emotion recognition as compared to other modalities. In this work, an integrated network, which is capable of recognizing emotion intensity levels from facial images in real time using deep learning technique is proposed. The cognitive study of facial expressions based on expression intensity levels are useful in applications such as healthcare, coboting, Industry 4.0 etc. This work proposes to augment emotion recognition with 2 other important parameters, valence and emotion intensity. This helps in better automated responses by a machine to an emotion. The valence model helps in classifying emotion as positive and negative emotions and discrete model classifies emotions as happy, anger, disgust, surprise and neutral state using Convolution Neural Network (CNN). Feature extraction and classification are carried out using CMU Multi-PIE database. The proposed architecture achieves 99.1% and 99.11% accuracy for valence model and discrete model respectively for offline image data with 5-fold cross validation. The average accuracy achieved in real time for valance model and discrete model is 95% & 95.6% respectively. Also, this work contributes to build a new database using facial landmarks, with three intensity levels of facial expressions which helps to classify expressions into low, mild and high intensities. The performance is also tested for different classifiers. The proposed integrated system is configured for real time Human Robot Interaction (HRI) applications on a test bed consisting of Raspberry Pi and RPA platform to assess its performance.     

唤醒定义探析及其认知神经生理基础

唤醒是衡量机体清醒程度和做出反应前准备程度的指标, 其水平可从睡眠到觉醒的连续体上变化, 具有独特的生理机制与神经回路。由于唤醒与情绪关联密切, 唤醒度这个概念常被认为等同于情绪强度, 但情绪强度实际上是唤醒和效价的和向量。受到Lazarus提出的“刺激”定义情绪思想的启发, 对唤醒的内含和心理机制进行了探析, 发现对不符合预期刺激出现的紧急准备是唤醒系统的主要功能, 预期性相关机制是唤醒的重要认知加工机制。其它因素(刺激属性、个体差异等)可能存在以下影响唤醒的原因：改变处理刺激时所需的资源量、影响预期机制。未来研究可从心理唤醒与生理唤醒的关系、唤醒的测量方法、唤醒度与情绪强度的关系、人类临床精神疾病的唤醒特征等角度推动唤醒的基础和应用研究。     

Disentangling the effects of choice and intensity on affective response to and preference for self-selected- versus imposed-intensity physical activity

ObjectiveTo examine the independent effects of physical activity (PA) intensity and choice of PA intensity when comparing affective response to and relative preference for self-selected-intensity versus imposed higher intensity PA.DesignWithin-subjects experiment.MethodsTwenty-nine healthy, low-active women completed four PA bouts over two sessions. The first session consisted of a one-third mile self-selected-intensity treadmill walk during which the speed was recorded, but was not visible to the participants. The second session consisted of three, counterbalanced, one-third mile treadmill conditions: (a) self-selected intensity, (b) same intensity as recorded for the first-session-self-selected-intensity walk, but with the intensity imposed by the experimenter (i.e., yoked-self-selected intensity), and (c) intensity set at 20% higher than the first-session-self-selected-intensity walk (imposed higher intensity). Acute affective valence (pleasure/displeasure) was recorded prior to, during, and following each walking bout. Preference for each walking intensity was assessed using a behavioral-choice paradigm.ResultsContrary to hypotheses, there was no effect of condition on acute affective valence. However, consistent with hypotheses, there was a linear trend, F(1, 22) = 11.00, p = .003, indicating preference in descending order from self-selected-intensity to yoked-self-selected-intensity to imposed higher intensity PA.ConclusionsBoth choice over the intensity and a lower intensity per se contributed to greater preference for self-selected-intensity over imposed higher intensity PA among healthy low-active women; however, there was no evidence to support the notion that affective response to PA mediated this relationship.

Face in profile view reduces perceived facial expression intensity: An eye-tracking study

Recent studies measuring the facial expressions of emotion have focused primarily on the perception of frontal face images. As we frequently encounter expressive faces from different viewing angles, having a mechanism which allows invariant expression perception would be advantageous to our social interactions. Although a couple of studies have indicated comparable expression categorization accuracy across viewpoints, it is unknown how perceived expression intensity and associated gaze behaviour change across viewing angles. Differences could arise because diagnostic cues from local facial features for decoding expressions could vary with viewpoints. Here we manipulated orientation of faces (frontal, mid-profile, and profile view) displaying six common facial expressions of emotion, and measured participants' expression categorization accuracy, perceived expression intensity and associated gaze patterns. In comparison with frontal faces, profile faces slightly reduced identification rates for disgust and sad expressions, but significantly decreased perceived intensity for all tested expressions. Although quantitatively viewpoint had expression-specific influence on the proportion of fixations directed at local facial features, the qualitative gaze distribution within facial features (e.g., the eyes tended to attract the highest proportion of fixations, followed by the nose and then the mouth region) was independent of viewpoint and expression type. Our results suggest that the viewpoint-invariant facial expression processing is categorical perception, which could be linked to a viewpoint-invariant holistic gaze strategy for extracting expressive facial cues.     

Developing Metacompetence in Low Intensity Cognitive‐Behavioural Therapy (CBT) Interventions: Evaluating a Self‐Practice/Self‐Reflection Programme for Experienced Low Intensity CBT Practitioners

Self‐practice/self‐reflection (SP/SR) is a targeted training and professional development strategy in which clinicians practice cognitive‐behavioural therapy (CBT) techniques and processes on themselves and then working through a structured process of self‐reflection. Previous studies with CBT trainees and experienced mental health practitioners have found that SP/SR or experiencing CBT “from the inside out” has been perceived by participants as increasing competency in a number of important areas and increasing therapist flexibility and artistry. Low intensity (LI) practitioners are identified as a relatively new addition to mental health service delivery in the UK. These workers are differentiated from traditional mental health practitioners by a shorter training period, the delivery of a circumscribed number of CBT interventions, and a very high weekly patient load. This study, the first of its kind, reports outcomes from an SP/SR programme undertaken by seven experienced LI CBT practitioners. Participants used the following measures to track their experience of the programme: time spent on programme, personal‐ and therapy‐related belief rating, goals attained, and perceived skill rated for average and most difficult patients. Results showed a positive change in work‐related skill and behaviour change, particularly when working with the more difficult patients. The findings are consistent with those found in other groups of therapists (e.g., trainee CBT therapists and highly experienced CBT therapists), suggesting that SP/SR may be a valuable addition to LI intensity training and professional development. These findings are discussed in the context of the particular needs of LI practitioners.     

Intensifying attachment-related sadness and decreasing anger intensity among individuals suffering from unresolved anger: The role of relational reframe followed by empty-chair interventions

This study examined whether two therapy interventions – relational reframe followed by empty chair – were associated with increases in sadness intensity and decreases in anger intensity among a sample of 61 undergraduate students suffering from unresolved anger toward an attachment figure (e.g. parent, sibling, and past-romantic partner). Participants underwent a single analog therapy session comprised of three interventions delivered in sequence: empathic focus on their anger; relational reframe; and empty-chair enactment. Participants retrospectively reported on the intensity of their attachment-related anger and sadness during the session using an interpersonal process recall procedure. Results showed that over the course of the relational reframe and empty-chair intervention sequence, sadness intensity increased and anger intensity decreased. Theoretical and practical implications are discussed.     

From Combat to Khakis: An Exploratory Examination of Job Stress With Veterans

Veterans are having a difficult time reintegrating back into the civilian sector following their service, with nearly 44% reporting some type of problem. The experienced stress and resultant strain associated with this reintegration may be caused by an incongruence between veterans’ military identities and their civilian work environments, a form of strain we term veteran identity strain (Vet-IS). To better understand the experienced strain associated with incongruent veteran and civilian work identities, we examine the effects of military rank on Vet-IS, the moderating role of political skill on the relationship between rank and Vet-IS, and how this relationship affects the outcomes of work intensity and vigor. A mediated moderation analysis of 251 veterans provided support for most study hypotheses, which predicted that rank would have an indirect effect on work intensity and vigor through Vet-IS, conditional upon veterans’ levels of political skill. Contributions and future research directions are discussed.
