Changes of autonomic nervous system physiological response following occurring Core-affect

Q: What is the clinical evidence from this study?

Study design: Other. Population: Healthy volunteers (n=19). Intervention: Emotion-eliciting images (OASIS) vs. Different valence and arousal conditions. Primary outcome: Skin conductance level (SCL) change by valence (p=<0.001).

Key Result

Viewing negative emotion-eliciting images significantly increased skin conductance level and decreased heart rate compared to other conditions.

Structured PICO

Population

19 police officers (15 male, 4 female, mean age 34.3 years, SD 5.4)

Intervention

Presentation of emotion-eliciting images (Open Affective Standardized Image Set: OASIS) for 30 seconds per image

Comparator

Resting state and 30-second recovery periods

Outcome

Changes in autonomic nervous system physiological responses (EDA, HR, NPV, respiration, facial muscles)surrogate

Emotion-eliciting images successfully induced changes in autonomic nervous system responses, particularly skin conductance and heart rate, suggesting potential for emotion detection in forensic contexts.

Main Result

p-value: p=<0.001

Limitations

Did not consider time-series changes in physiological response patterns over time.
Only valence was successfully elicited by the images, indicating a need for better core-affect elicitation methods.
Need for experimental methods that are closer to real-world situations.

Yamaguchi et al. (Wed,) conducted a other in Healthy volunteers (n=19). Emotion-eliciting images (OASIS) vs. Different valence and arousal conditions was evaluated on Skin conductance level (SCL) change by valence (p=<0.001). Viewing negative emotion-eliciting images significantly increased skin conductance level and decreased heart rate compared to other conditions.
