Speed-accuracy tradeoffs – being fast at the risk of being wrong – are
fundamental to many decisions and natural selection is expected to resolve
these tradeoffs according to the costs and benefits of behavior. We here
test the prediction that females and males should integrate information
from courtship signals differently because they experience different
payoffs along the speed-accuracy continuum. We fitted a neural model of
decision making (a drift-diffusion model of integration to threshold) to
behavioral data from the grasshopper Chorthippus biguttulus to determine
the parameters of temporal integration of acoustic directional information
used by male grasshoppers to locate receptive females. The model revealed
that males had a low threshold for initiating a turning response, yet a
large integration time constant enabled them to continue to gather
information when cues were weak. This contrasts with parameters estimated
for females of the same species when evaluating potential mates, in which
response thresholds were much higher and behavior was strongly influenced
by unattractive stimuli. Our results reveal differences in neural
integration consistent with the sex-specific costs of mate search: Males
often face competition and need to be fast, while females often pay high
error costs and need to be deliberate.
