Rapid extraction of mean emotion and gender from sets of faces. (2007, neutral): “Error bars in (B and F) indicate 95% confidence intervals based on 5000 Monte Carlo simulations [11], and error bars in (D) are ± 1 SEM.”
Motion-dependent representation of space in area MT+ (2013, positive): “…we fitted cumulative Gaussian functions to observers' responses, estimated PSEs where the flashes in physically shifted positions were perceived in the same positions as those presented during motion, and determined confidence intervals for these values (Wichmann and Hill, 2001a, 2001b).”
‘When Birds of a Feather Flock Together’: Synesthetic Correspondences Modulate Audiovisual Integration in Non-Synesthetes (2009, methodology): “Separate psychometric functions for congruent and incongruent trials were calculated for each participant by fitting the ratios of ‘‘auditory second’’ responses plotted against SOAs with a cumulative Gaussian distribution [29] (see Fig.”
Visual-haptic cue weighting is independent of modality-specific attention. (2008, positive): “To obtain psychometric functions , the data were fitted with cumulative Gaussians free to vary in position ( PSE ) and slope ( JND ) using the software package psignifit ( see http : / / bootstrap - software . org / psignifit / ; Wichmann & Hill , 2001 ) .”
Categorization difficulty is associated with negative evaluation in the “uncanny valley” phenomenon (2013, methodology): “Yamada, Kawabe, & Ihaya (in press)”
Cross-correlation between auditory and visual signals promotes multisensory integration. (2013, methodology): “…functions were calculated for each level of correlation and for each participant by fitting the ratios of ‘right’ responses plotted against spatial displacement (measured in degrees of visual angle) with a cumulative Gaussian distribution (see Wichmann and Hill, 2001, for full procedural details).”
Response Errors Explain the Failure of Independent-Channels Models of Perception of Temporal Order (2012, methodology): “Thus, we estimated parameters and measured the goodness of the fit using the same “currency” (Wichmann and Hill, 2001).”
