Abstract： Emotions surface during interaction between individuals. Thus, an accurate recognition of facial expressions is essential in the realm of social interactions. In recent years, numerous studies have revealed that individuals not only depend on facial configuration information for identifying facial expressions but also place considerable emphasis on contextual information extracted from external cues beyond the face. People’s behavior frequently unfolds within intricate social group dynamics, wherein individuals often perceive and interpret the facial expressions of their fellow group members during interaction. However, the impact of group information on facial expression recognition, being an essential social contextual factor, remains somewhat unclear. Hence, three experiments were conducted to investigate the influence exerted by group information on the recognition of facial expressions.
The stimuli used in the study were happy, fearful, and neutral face images selected from the NimStim set, including 15 pictures (seven females) of each of the aforementioned emotions. Group information was manipulated following the presentation of a fixation cross through perceptual cues. Subsequently, during the facial expression recognition phase, participants were instructed to recognize the facial expressions exhibited by target individuals. In the first experiment, participants were instructed to rate the intensity of target facial expressions on a six-emotion scale, and the surrounding facial expressions were always congruent with the target facial expressions. A total of 29 college students (16 females, mean age 20.00 ± 1.80 years) were recruited to participate in this experiment. In Experiments 2 and 3, we manipulated the emotional congruency between the surrounding faces and the target faces during the facial expression recognition phase. Additionally, we controlled for variations in physical characteristics across different experimental conditions. The task requirement of Experiment 2 was the same as those of Experiment 1. However, in Experiment 3, participants were instructed to judge the target facial expressions by pressing corresponding keys on the keyboard as quickly and accurately as possible. A total of 26 college students (14 females, mean age 21.15 ± 1.99 years) participated in Experiment 2, and 32 college students (15 females, mean age 21.20 ± 1.60 years) participated in Experiment 3.
Results revealed the following: (1) Compared with emotion-incongruent conditions, emotional congruency between target faces and surrounding faces resulted in shorter RTs and higher accuracy. (2) Group information regulated the influence of surrounding facial expressions on target facial expression recognition. Specifically, under group conditions, participants tended to recognize target facial expressions according to the emotional state of the surrounding faces. When the target facial expressions in line with the expectations established by the participants that group members have congruent emotional state, the recognition of target facial expressions was faster and more accurate than incongruent conditions. However, under nongroup conditions, participants recognized target facial expressions without reference to the emotional states of the surrounding faces. (3) Participants exhibited a faster and more accurate recognition of happy faces, indicating the recognition advantage effect for happy facial expressions.
Results revealed that group information influenced facial expression recognition, individuals recognized facial expressions based on the social relationship between the interactions, and understanding social interaction plays an important role in the process of emotion perception.
