Measures of noise filtering and amplification for individual visual areas. A: attention effect (attended-unattended classification performance) for each visual area in the high-noise condition. B: attention effect in the no-noise condition. C: parameter estimates of noise filtering from perceptual template model (PTM) fits to each visual area. D: parameter estimates of amplification from PTM fits. Parameter estimates that significantly exceed 1.0 indicate a reliable multiplicative effect; asterisks and black circles denote significant (P < 0.05) and marginally significant (P < 0.1) effects, respectively. Error bars denote standard errors.
