When both movie and test face were presented without noise, test face age ratings were attracted toward 28% of the movie. White and black circles indicate zero (0%) and full (100%) attraction toward the beginning of the movie. Increasing (A) and decreasing (B) age directions were equally balanced. Attraction percentage was computed as age difference between reference faces (e.g., reference face: old) and test faces (e.g., movie: young to old test face: old) divided by the total age range (e.g., old reference face − young reference face). The young test face was rated as much older than what it actually was (green bracket). ( B) A fourth group was presented with a face morphing movie gradually rejuvenating from old to young and was then asked to rate the age of the young face embedded in a blue frame (blue square test face). Although the test face and reference faces are identical, the old test face was rated as much younger than what it actually was (green bracket). A third group was presented with a face morphing movie gradually aging from young to old and was then asked to rate the age of the old face embedded in a blue frame (blue circle, test face). Two groups of observers were asked to rate the age of a young or old static face embedded in a blue frame (white square and circle reference faces). Thus, every experiment consisted of one-shot independent trials, from independent subjects who had no prior knowledge or experience with the stimulus or task. In addition, each participant completed one, and only one, single trial across all our experiments. Participants were made aware of the age rating task only after the task-irrelevant movie, when the static face and blue frame appeared they were not warned, cued, or asked to make any explicit decision about the movie while watching it. For simplicity, we will refer to the rating of the static face alone as the “reference face” (white data points) and to ratings of the static face preceded by the movie as the “test face” (blue circle). These observers then rated the age of the old face embedded in a blue frame (20.2 years Fig.

A third group of 47 independent participants were presented with a movie of a face that morphed gradually, aging from young to old. In experiment 1, two separate groups of 44 and 45 participants rated on Mechanical Turk the age of a young or old static face embedded in a blue frame (13 and 25.5 years, respectively Fig.
