Specifically, we sought to elucidate the workings of “process-specific” effects of motivation on cue- and target-related processing during these attentional tasks. Non-specific motivational effects due to effort and arousal were removed by using a hybrid task design that included: (1) event-related (i.e., transient) components with relatively long, jittered and optimized intertrial and interstimulus intervals between cue and target periods; and (2) a blocked (i.e., sustained) motivational component. Hybrid designs allow for separate estimates of transient and sustained signals (Visscher et al., 2003). Importantly, transient processes could be dissociated from each other, i.e., cue- and target-related responses.","tracks":[{"project":"0_colil","denotations":[{"id":"20859524-19434242-131716","span":{"begin":95,"end":99},"obj":"19434242"},{"id":"20859524-12948724-131717","span":{"begin":791,"end":795},"obj":"12948724"}],"attributes":[{"subj":"20859524-19434242-131716","pred":"source","obj":"0_colil"},{"subj":"20859524-12948724-131717","pred":"source","obj":"0_colil"}]},{"project":"TEST0","denotations":[{"id":"20859524-95-103-131716","span":{"begin":95,"end":99},"obj":"[\"19434242\"]"},{"id":"20859524-97-105-131717","span":{"begin":791,"end":795},"obj":"[\"12948724\"]"}],"attributes":[{"subj":"20859524-95-103-131716","pred":"source","obj":"TEST0"},{"subj":"20859524-97-105-131717","pred":"source","obj":"TEST0"}]},{"project":"2_test","denotations":[{"id":"20859524-19434242-38088797","span":{"begin":95,"end":99},"obj":"19434242"},{"id":"20859524-12948724-38088798","span":{"begin":791,"end":795},"obj":"12948724"}],"attributes":[{"subj":"20859524-19434242-38088797","pred":"source","obj":"2_test"},{"subj":"20859524-12948724-38088798","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"0_colil","color":"#9399ec","default":true},{"id":"TEST0","color":"#b3ec93"},{"id":"2_test","color":"#ec93cd"}]}]}}
