Brief Affect Recognition Thresholds: A Systematic Evaluation of The Japanese and Caucasian Brief Affect Recognition Test
… the involuntary expression. As such, correct recognition can have important benefits. The Japanese and Caucasian Brief Affect Recognition Task (JACBART) has been proposed as the standardized measure of affect recognition capabilities with micro-expression durations (i.e., facial expressions …

Wearable and automotive systems for affect recognition from physiology
… have been designed and built to recognize affective patterns in physiological signals. Experiments were conducted for evaluation of the new systems and algorithms in three types of settings: a highly constrained laboratory setting, a largely unconstrained ambulatory environment, and a less …

Influence of environmental context on affect recognition of stylized movements
… and stylized walking sequences both impact affect recognition. In the first two studies, participants were asked to categorize stimuli as one of seven affective labels. The results show that the labels were not applied consistently and so it was concluded that the affect of a …

Facial Affect Recognition and Interpretation in Adolescents At Risk for Developing Bipolar Disorder
… developing bipolar disorder (BPD) have facial affect processing deficits as well as to examine the relationship between affect processing and family environment. Participants with a family history of bipolar disorder with (AR + BPD) and without (AR) the disorder themselves were compared with …

Trauma, PTSD, and the processing of emotional information: The utility of examining facial affect recognition and emotional context
… method of examining emotional processing, facial affect recognition. In Study 1, I created a new stimulus set of facial expressions and contextual backgrounds, the Contextual Recognition of Affect Faces Task (CRAFT), in which participants view faces displaying different facial expressions (i.e., …

Social-Emotional Processing and Bullying Behaviour
… the relation between poorer empathy and facial affect recognition and aggressive behaviour is well documented, few studies have examined these individual characteristics and bullying behaviour. Moreover, research to date presents conflicting results, making it difficult to form conclusions and …

Social information processing in aggressive and withdrawn preschool children
… children, and by employing traditional affect recognition tasks as the stimuli. Sixty preschool children were nominated by their classroom teachers as either aggressive, withdrawn, or well adjusted, according to their predominant interaction style. The children were then tested, using a …

Assessing the co-occurrence of psychological well-being in the intimate relationships of ex-services personnel in Northern Ireland
… in emotional processing, specifically in facial affect recognition. The questionnaire data was analysed primarily through dyadic Actor-Partner-Interdependence-Models. The eye tracking study used the Facial Affect Recognition Task and the Contextual Recognition of Affect Faces Task, in which …

Perceptual Thresholds in Informative Audio: The Effects of Sound Variation in Interactive Systems
… thesis investigates how sound modifications affect recognition and meaning in interactive systems. Using a custom-built game, participants learned three real-world sounds and identified them under pitch shifting, flanger effects, and time stretching. A second task let participants indicate …

Investigating the Use of Physiological and Behavioral Signals to Facilitate Empathic Human-AI Interaction for Daily Stress Management
… signals to infer users' mental states (affective and cognitive) and accordingly generate empathic messages as adaptive interventions. Three core research goals guided this work: (1) systematically reviewing state-of-the-art methods for stress and affect recognition with physiological …

Affective state recognition in Virtual Reality from electromyography and photoplethysmography using head-mounted wearable sensors.
The three core components of Affective Computing (AC) are emotion expression recognition, emotion processing, and emotional feedback. Affective states are typically characterized in a two-dimensional space consisting of arousal, i.e., the intensity of the emotion felt; and valence, i.e., the degree …

Attention-Deficit/Hyperactivity Disorder Symptoms as a Mediator of the Relation Between Social Perception and Social Skills and Adaptability in Preschoolers
<p>ADHD symptoms have been linked empirically to both social perception deficits as well as impairments in social skills and adaptability. The current study built on existing literature by examining whether social perception abilities indirectly predicted social skills and adaptability through ADHD …
