The effect of adaptation to emotional facial expressions occurs after a prolonged observation of an intense display of a basic emotion (the adaptor) which biases the perception of a subsequent briefly presented face away from the adaptor . Previous studies of this effect mostly explored static images of facial expressions . We conducted two experiments to examine the features of adaptation to dynamic facial expressions . In Experiment 1 , we created three types of adaptors based on video clips of the face of a female model who demonstrated the transitions between expressions of happiness and sadness . The adaptors included static expressions , dynamic expressions and dynamic changes from one expression to another . We expected the perception of the test stimuli to be biased away from the emotion displayed in the static adaptors or from the emotion at the end of the dynamic adaptors . The results showed that the static and dynamic expressions resulted in adaptation effects of the same size , and no adaptation occurred to the dynamic changes between two expressions . In Experiment 2 , we tested the hypothesis that adaptation to dynamic changes of expression occurs if the duration of the adaptor is doubled (from 5 to 10 seconds) . The results of the experiment supported the hypothesis . Overall , we confirmed the effect of adaptation to the emotional content of a facial expression . No adaptation to the temporal structure of the expression (forward versus reversed in time) was found .
