This study examined how one's own posture influences the perception of another's posture in a task with implicit affective information. In 2 experiments, participants assumed or viewed a body posture and then compared that posture with a viewed posture. They were not told that postures varied in affective valence: positive, negative, neutral-abstract, or neutral-meaningful. Posture affect influenced both accuracy and response time measures of posture discrimination. Participants were slower and less accurate for targets that matched an assumed posture, but only for affective postures. This pattern did not hold for matching affectively neutral postures (meaningful or not), nonmatching postures, or for purely visual comparisons. These results are consistent with both cognitive embodiment theories postulating that personal body posture influences the perception of other's postures and emotional embodiment theories postulating sensorimotor and emotional simulation processes that create correspondences between one's own and another's emotional postures. Nonetheless, these findings differ from studies finding facilitation for explicit emotional judgments of affective congruence. People use different information depending on task requirements. The assumption of an affective posture may activate simulations of personal emotional experiences that may, in turn, serve to differentiate personal posture perception from ostensibly the same posture in another person.

Background/Methods:  Sensory processing capacities of 8–12‐year‐old internationally adopted (IA) children who experienced prolonged institutional care (> 12 months with 75% of pre‐adoption lives in institutional care) prior to adoption into family environments (PI) were compared to a group of IA children who were adopted early (< 8 months) predominantly from foster care with little or no institutional experience (EA/FC) and another group of non‐adopted (NA) children raised by their birth parents in the United States. All children had estimated IQs within the normal range and did not evidence major neurodevelopmental disorders (e.g., cerebral palsy, fetal alcohol syndrome, Down’s syndrome). Sensory processing was evaluated with a commonly used parent‐report measure and a laboratory assessment. Results:  Children who had experienced prolonged institutionalization showed higher levels of reactivity to sensation and displayed both more aversion and approach to sensory stimuli than the other groups. The comparison groups (EA/FC & NA) did not differ on any of the sensory processing measures. Conclusions:  These results suggest that early institutional rearing which typically involves both sensory and social deprivation is associated with problems in sensory modulation capacities.
