Brainstem response and state-trait variables

A series of investigations are summarized from a personality research program that have relevance for mental state estimation. Of particular concern are those personality variables that are believed to have either a biological or perceptual basis and their relationship to human task performance and psychophysiology. These variables are among the most robust personality measures and include such dimensions as extraversion-introversion, sensation seeking, and impulsiveness. These dimensions also have the most distinct link to performance and psychophysiology. Through the course of many of these investigations two issues have emerged repeatedly: these personality dimensions appear to mediate mental state, and mental state appears to influence measures of performance or psychophysiology

Psychophysiology

Abstract Joint performance can lead to the synchronization of physiological processes among group members during a shared task. Recently, it has been shown that synchronization is indicative of subjective ratings of group processes and task performance. However, different methods have been used to quantify synchronization, and little is known about the effects of the choice of method and level of analysis (individuals, dyads, or triads) on the results. In this study, participants performed a decision-making task in groups of three while physiological signals (heart rate and electrodermal activity), positive affective behavior, and personality traits were measured. First, we investigated the effects of different levels of analysis of physiological synchrony on affective behavior. We computed synchrony measures as (a) individual contributions to group synchrony, (b) the average dyadic synchrony within a group, and (c) group-level synchrony. Second, we assessed the association between physiological synchrony and positive affective behavior. Third, we investigated the moderating effects of trait anxiety and social phobia on behavior. We discovered that the effects of physiological synchrony on positive affective behavior were particularly strong at the group level but nonsignificant at the individual and dyadic levels. Moreover, we found that heart rate and electrodermal synchronization showed opposite effects on group members' display of affective behavior. Finally, trait anxiety moderated the relationship between physiological synchrony and affective behavior, perhaps due to social uncertainty, while social phobia did not have a moderating effect. We discuss these results regarding the role of different physiological signals and task demands during joint action

Psychophysiology in games

Psychophysiology is the study of the relationship between psychology and its physiological manifestations. That relationship is of particular importance for both game design and ultimately gameplaying. Players’ psychophysiology offers a gateway towards a better understanding of playing behavior and experience. That knowledge can, in turn, be beneficial for the player as it allows designers to make better games for them; either explicitly by altering the game during play or implicitly during the game design process. This chapter argues for the importance of physiology for the investigation of player affect in games, reviews the current state of the art in sensor technology and outlines the key phases for the application of psychophysiology in games.The work is supported, in part, by the EU-funded FP7 ICT iLearnRWproject (project no: 318803).peer-reviewe

Psychophysiology-based QoE assessment : a survey

We present a survey of psychophysiology-based assessment for quality of experience (QoE) in advanced multimedia technologies. We provide a classification of methods relevant to QoE and describe related psychological processes, experimental design considerations, and signal analysis techniques. We summarize multimodal techniques and discuss several important aspects of psychophysiology-based QoE assessment, including the synergies with psychophysical assessment and the need for standardized experimental design. This survey is not considered to be exhaustive but serves as a guideline for those interested to further explore this emerging field of research

Sensory Psychophysiology

Objective: Sensory processing issues can have a large negative impact on the ability to participate in daily occupations such as ADLs, access to work, school and leisure environments, and social interactions (Dunn, 2001). The evidence documenting sensory processing issues in adults is sparse. Physiological information can be used as objective evidence to support the claim that those with over-responsivity to sensations are experiencing their environment differently than the typical population. Understanding more about sensory processing in adults may lead to increased recognition of the problem and more opportunities for intervention to increase occupational participation. The purpose of this quantitative study compared the physiological responses to sensation in people who self-report as high in sensory sensitivity compared to people who self-report as low in sensory sensitivity. Method: Using a quasi-experimental design, physiological responses to sensation in typical adults was measured. The use of the Sensory Profile assessment as a behavioral self-reported measure was used as a pretest and the Sensory Challenge Protocol was used as our physiological outcome measure to quantify participants’ physiological responses to sensation.Results: No significant differences were shown between experimental and control groups in EDR responses to stimuli. Based on the sensory profile, participants’ in the experimental group who identified as sensory sensitive had higher EDR responses to more the intense sensations, such as mower (1.3), feather (1.8), and camphor (1.7). There is a significant correlation between low registration and sensory sensitive (.678), sensory avoidant (.847) and sensory defensive (.817) for the experimental group’s self-reported scores on the Sensory Profile supporting the idea that people who have sensory sensitivities may also suppress responses to sensation.Conclusion: There are differential, meaningful patterns observed in how people with sensory sensitivities are responding to sensations. There is high variability in individuals’ personal understanding of their own sensory sensitivities and what sensory stimuli they are responding to. Therefore, it is important to know and understand what certain people in the general population do because overtime it can lead to maladaptive behaviors in daily functioning.https://scholar.dominican.edu/ug-student-posters/1064/thumbnail.jp

Pengaruh Monoton, Kualitas Tidur, Psikofisiologi, Distraksi, Dan Kelelahan Kerja Terhadap Tingkat Kewaspadaan

Human beings as subjects who have limitations in work, thus causing the error. Human error committed resulted in a decreased level of alertness machinist and assistant machinist in the line of duty. Alert level is influenced by five factors: the state of monotony, quality of sleep, psychophysiology state, distraction and fatigue. Methods to measure five factors: mononton questionnaire, a questionnaire Pittsburgh Sleep Quality Index (PSQI) questionnaire General Job Stress and FAS questionnaire. Meanwhile, to test the level of vigilance using Software Psychomotor Vigilance Test (PVT). Respondents were selected is machinist and assistant machinist, because the type of work desperately need a high level of vigilance. The measurement results were analyzed using linear regression test compound. In this study produce state of monotony, quality of sleep, psychophysiology state, distraction and fatigue influential work simultaneously on the level of alertness. This is evidenced by when before official hours, the test results F-count state of monotony, quality of sleep, psychophysiology state is 0.876, while for the variable distraction and fatigue Work of the level of alertness has a value of 2.371. during and after work variable distraction and fatigue on the level of vigilance has 2,953 F-count value, and the value of 0,544 for the state of monotony, quality of sleep, psychophysiology circumstances. The factor that has the greatest influence on the level of vigilance before official hours of sleep is the quality factor, whereas for after hours services is a factor of fatigue
