Married couples in supportive relationships felt significantly less stressed while watching horror movie clips with their partner than without, as measured by pupil dilation.

‘Horror video clips elicited a stress response and there were significant differences between the support and non-support conditions, and marital relationship quality conditions.’

Eighty-three couples (166 participants) were quasi-grouped in this study, based on a self-reported multidimensional relationship quality scale, to either supportive or ambivalent marital relationship conditions.Read More..





They were then randomized to either spousal support (i.e., handholding) or non-support (spousal absence) condition and watched clips from both horror and nature movies while pupil dilation was measured.
Results shown that the horror video clips elicited a stress response and there were significant differences between the support and non-support conditions, as well as marital relationship quality conditions.
These results suggest the precision, speed, and sensitivity of pupillometry as a potentially fruitful method to investigate the causal mechanisms linking stress buffering and supportive marital relationships
