Couples' shared participation in novel and arousing activities and experienced relationship quality.

Using a newspaper questionnaire, a door-to-door survey, and 3 laboratory experiments, the authors examined a proposed effect of shared participation in novel and arousing activities on experienced relationship quality. The questionnaire and survey studies found predicted correlations of reported shared "exciting" activities and relationship satisfaction plus their predicted mediation by relationship boredom. In all 3 experiments, the authors found predicted greater increases in experienced relationship quality from before to after participating together in a 7-min novel and arousing (vs. a more mundane) task. Comparison with a no-activity control showed the effect was due to the novel-arousing task. The same effect was found on ratings of videotaped discussions before and after the experimental task. Finally, all results remained after controlling for relationship social desirability. Results bear on general issues of boredom and excitement in relationships and the role of such processes in understanding the typical early decline of relationship quality after the honeymoon period.

Sensory-processing sensitivity and its relation to introversion and emotionality.

Over a series of 7 studies that used diverse samples and measures, this research identified a unidimensional core variable of high sensory-processing sensitivity and demonstrated its partial independence from social introversion and emotionality, variables with which it had been confused or subsumed in most previous theorizing by personality researchers. Additional findings were that there appear to be 2 distinct clusters of highly sensitive individuals (a smaller group with an unhappy childhood and related variables, and a larger group similar to nonhighly sensitive individuals except for their sensitivity) and that sensitivity moderates, at least for men; the relation of parental environment to reporting having had an unhappy childhood. This research also demonstrated adequate reliability and content, convergent, and discriminant validity for a 27-item Highly Sensitive Person Scale.
