Temperament Trait

Sensory processing sensitivity (SPS) is a temperament trait found in around 20% of humans, which has been found to enhance responsiveness to diverse stimuli. In this study, we investigated for the first time the extent to which SPS, and its interaction with quality of parenting, predicts positive and negative experiences in response to emotional stimuli. Participants (N = 96) from the upper and lower quartiles on the standard SPS measure (the Highly Sensitive Person Scale) rated the valence and their arousal level when viewing emotionally evocative and neutral pictures selected from the International Affective Picture System. High (vs. low) SPS individuals rated pictures eliciting emotion, and especially positive ones, as significantly more valenced, and tended to respond faster to the positive pictures; also, high, vs. low, SPS individuals who had reported having high-quality parenting reported greater arousal in response to positive pictures. Overall, results suggest that high SPS individuals respond more strongly to emotional stimuli—especially positive—without being more aroused unless they had especially high-quality parenting.

Sensory Processing Sensitivity

<b><i>Background:</i></b> Sensory processing sensitivity (SPS) is a biologically based temperament trait associated with enhanced awareness and responsivity to environmental and social stimuli. Individuals with high SPS are more affected by their environments, which may result in overarousal, cognitive depletion, and fatigue. <b><i>Method:</i></b> We examined individual differences in resting-state (rs) brain connectivity (using functional MRI) as a function of SPS among a group of adults (<i>M</i> age = 66.13 ± 11.44 years) immediately after they completed a social affective “empathy” task. SPS was measured with the Highly Sensitive Person (HSP) Scale and correlated with rs brain connectivity. <b><i>Results:</i></b> Results showed enhanced rs brain connectivity within the ventral attention, dorsal attention, and limbic networks as a function of greater SPS. Region of interest analyses showed increased rs brain connectivity between the hippocampus and the precuneus (implicated in episodic memory); while weaker connectivity was shown between the amygdala and the periaqueductal gray (important for anxiety), and the hippocampus and insula (implicated in habitual cognitive processing). <b><i>Conclusions:</i></b> The present study showed that SPS is associated with rs brain connectivity implicated in attentional control, consolidation of memory, physiological homeostasis, and deliberative cognition. These results support theories proposing “depth of processing” as a central feature of SPS and highlight the neural processes underlying this cardinal feature of the trait.
