Unbiased recognition over time.

(A) Graphic of the unbiased ratings for every emotion at every gate. Shown is the unbiased estimated percentage of correct recognition of the emotion expressed for different lengths of stimulus presented (divided into 10 gates representing the percentage of the full stimulus presented, e.g., 10%, 20%…90%, and 100%). For example, 100% for Anger correspond to a group of stimuli with varying length ranging from 400 to 2250 that represent at least 90.1% of the original corresponding stimulus. The mean duration for this group corresponds to 1244 and is used to represent this specific gate. The recognition percentages were computed with the confusion matrix based on continuous responses from participants. Continuous thinner lines represent the best polynomial fit based on the orthogonal polynomial contrasts and RMSE performed in Table 3 (anger: cubic, disgust: quadratic, fear: linear, sadness: linear, joy: linear, neutral: linear). (B) Graphic of the linear mixed model outputs using duration and emotion presented (model with four gates). Shown is the unbiased estimated percentage of correct recognition of the emotion as expressed over time (divided into four gates representing the percentage of the full stimulus presented, e.g., 25%, 50%, 75%, and 100%). The values were computed with a linear mixed model that evaluated the percentage of correctness using the emotion expressed, the gate duration, and their interaction as predictors. The error bars represent the confidence interval at 95%.
