Participants were presented with 8 faces on a computer displaying prototypical expressions of fear and happiness, and a neutral face (29) morphed at 30% (low), 60% (medium), and 100% (high intensity) of the expression along the neutral-prototypic continuum. A total 168 stimuli were presented in a random order for 500 ms each, with intertrial interval varying according to a Poisson distribution (mean=5000 ms). Participants indicated the gender of each face by a key press. Behavioral responses (accuracy and RT) were recorded using Presentation (Neurobehavioral Systems, Albany, CA).","divisions":[{"label":"Title","span":{"begin":0,"end":26}}],"tracks":[{"project":"NEUROSES","denotations":[{"id":"T182","span":{"begin":534,"end":546},"obj":"PATO_0000060"},{"id":"T183","span":{"begin":7,"end":21},"obj":"PATO_0000189"},{"id":"T184","span":{"begin":304,"end":307},"obj":"PATO_0000471"}],"attributes":[{"subj":"T182","pred":"source","obj":"NEUROSES"},{"subj":"T183","pred":"source","obj":"NEUROSES"},{"subj":"T184","pred":"source","obj":"NEUROSES"}]},{"project":"2_test","denotations":[{"id":"25035080-19182175-76159682","span":{"begin":117,"end":121},"obj":"19182175"},{"id":"25035080-23343526-76159683","span":{"begin":143,"end":147},"obj":"23343526"}],"attributes":[{"subj":"25035080-19182175-76159682","pred":"source","obj":"2_test"},{"subj":"25035080-23343526-76159683","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"NEUROSES","color":"#ecd593","default":true},{"id":"2_test","color":"#bb93ec"}]}]}}
