#' Perceptual discrimination of short-duration gabor patches with Perceptual
#' Awareness Scale ratings.
#'
#' The Perceptual Awareness Scale ratings ('no experience', ..., 'absolutely
#' clear image') of discrimination responses to gabor patches presented for 32ms
#' or 64ms before or after the ratings were provided.
#'
#' On each trial participants had to classify the briefly presented
#' gabor patch as either oriented to the left or to the right using
#' the arrow keys. The participants were also asked to rate the
#' stimuli on a 4 point Perceptual Awareness Scale presented at the
#' bottom of the screen. The gabor patch was immediately followed by a
#' mask. The PAS ratings ranged from "no experience" to
#' "absolutely clear image" and were provided either before
#' (RATING-DECISION condition) or after (DECISION-RATING condition)
#' pressing the arrow keys. On each trial the gabor patch was equally
#' likely to be presented for 32ms or 64ms. Decision-rating order was
#' a between-subject variable and gabor patch presentation duration
#' was a within-subject variable. There were 47 participants and 48
#' trials per condition.
