The authors explored three properties of basic, unconsciously triggered affective reactions: They can influence consequential behavior, they work without eliciting conscious feelings, and they interact with motivation. The authors investigated these properties by testing the influence of subliminally presented happy versus angry faces on pouring and consumption of beverage (Study 1), perception of beverage value (Study 2), and reports of conscious feelings (both studies). Consistent with incentive motivation theory, the impact of affective primes on beverage value and consumption was strongest for thirsty participants. Subliminal smiles caused thirsty participants to pour and consume more beverage (Study 1) and increased their willingness to pay and their wanting more beverage (Study 2). Subliminal frowns had the opposite effect. No feeling changes were observed, even in thirsty participants. The results suggest that basic affective reactions can be unconscious and interact with incentive motivation to influence assessment of value and behavior toward valenced objects.

Humans, infants and adults alike, automatically mimic a variety of behaviors. Such mimicry facilitates social functioning, including establishment of interpersonal rapport and understanding of other minds. This fundamental social process may thus be impaired in disorders such as autism characterized by socio-emotional and communicative deficits. We examined automatic and voluntary mimicry of emotional facial expression among adolescents and adults with autistic spectrum disorders (ASD) and a typical sample matched on age, gender and verbal intelligence. Participants viewed pictures of happy and angry expressions while the activity over their cheek and brow muscle region was monitored with electromyography (EMG). ASD participants did not automatically mimic facial expressions whereas the typically developing participants did. However, both groups showed evidence of successful voluntary mimicry. The data suggest that autism is associated with an impairment of a basic automatic social-emotion process. Results have implications for understanding typical and atypical social cognition.

Objective To document sensory sensitivities to nonnoxious sensory stimuli in daily life for participants with fibromyalgia (FM). Design Descriptive study of a convenience sample using a self-report survey of sensory processing. Setting Participants were recruited from the general community. The procedure took place in a research room at the University of Wisconsin-Madison. Participants Women with FM (n=27) were compared with women with rheumatoid arthritis (RA) (n=28) and healthy pain-free women (controls) (n=28) (N=83). Interventions Not applicable. Main Outcome Measure A self-report measure of sensory sensitivity to stimuli encountered in daily life. Items ask participants if they are sensitive to sensations that do not seem to bother other people or avoid common activities or environments because of sensory stimuli. Results The FM group reported significantly increased sensory sensitivities to both somatic (tactile) and nonsomatic (eg, auditory and olfactory) sensory stimuli compared with the RA and control groups. The RA and control groups did not differ in reported hypersensitivities. Conclusions Women with fibromyalgia reported increased sensitivities to stimuli in the environment and could experience more stress related to sensory conditions in daily life.

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.
