Resumo(s)
Relationships between accuracy and speed of decision-making, or
speed-accuracy tradeoffs (SAT), have been extensively studied.
However, the range of SAT observed varies widely across studies
for reasons that are unclear. Several explanations have been
proposed, including motivation or incentive for speed vs.
accuracy, species and modality but none of these hypotheses has
been directly tested. An alternative explanation is that the
different degrees of SAT are related to the nature of the task being
performed. Here, we addressed this problem by comparing SAT
in two odor-guided decision tasks that were identical except for
the nature of the task uncertainty: an odor mixture categorization
task, where the distinguishing information is reduced by making
the stimuli more similar to each other; and an odor identification
task in which the information is reduced by lowering the intensity
over a range of three log steps. (...)
