Repeated exposure decreases aesthetic chills likelihood but increases intensity

Area of Science:

• Psychophysiology
• Neuroscience
• Psychology

Background:

• Aesthetic chills, characterized by physiological responses like goosebumps, are linked to dopaminergic activity.
• Previous research on aesthetic chills has been limited by the lack of validated stimuli databases for repeated exposure studies.

Purpose of the Study:

• To investigate the impact of repeated exposure to validated aesthetic stimuli on the frequency and intensity of aesthetic chills.
• To explore potential habituation or fatigue effects and individual response variability in aesthetic chills.

Main Methods:

• Utilized a gold-standard database of 6 pre-validated chill-evoking stimuli.
• Employed a counterbalanced, randomized exposure order for 58 participants.
• Analyzed frequency, intensity, and duration of aesthetic chills across successive exposures.

Main Results:

• A significant decrease in the likelihood of experiencing aesthetic chills was observed with repeated exposure, suggesting habituation or stimulus fatigue.
• Participants who continued to experience chills showed an increase in intensity and duration over successive exposures.
• Distinct demographic and psychophysiological response patterns were identified, highlighting individual variability.

Conclusions:

• Aesthetic chills exhibit dynamic changes with repeated exposure, involving both decreased likelihood and potentially intensified experiences.
• Findings offer insights into emotional and reward processing, and the neural mechanisms underlying aesthetic experiences.
• Individual differences in psychophysiological responses underscore the complexity of aesthetic perception.
