The present study investigated if the gaze-cuing effect (i.e., the tendency for observers to respond faster to targets in locations that were cued by others' gaze direction than to not-cued targets) is modulated by the type of relationship (i.e., cooperative or competitive) established during a previous interaction with a cuing face. In two experiments, participants played a series of single-shot games of a modified version of the two-choice Prisoner's Dilemma against eight simulated contenders. They were shown a fictive feedback indicating if the opponents chose to cooperate or compete with them. Opponents' faces were then used as stimuli in a standard gaze-cuing task. In Experiment 1 females classified as average in competitiveness were tested, while in Experiment 2 females classified as high and low in competitiveness were tested. We found that only in females classified as low and average in competitiveness the gaze-cuing effect for competitive contenders was greater than for cooperative contenders. These findings suggest that competitive opponents represent a relevant source of information within the social environment and female observers with low and average levels of competition cannot prevent from keeping their eyes over them.

In the present study, we examine how person categorization conveyed by the combination of multiple cues modulates joint attention. In three experiments, we tested the combinatory effect of age, sex, and social status on gaze-following behaviour and pro-social attitudes. In Experiments 1 and 2, young adults were required to perform an instructed saccade towards left or right targets while viewing a to-be-ignored distracting face (female or male) gazing left or right, that could belong to a young, middle-aged, or elderly adult of high or low social status. Social status was manipulated by semantic knowledge (Experiment 1) or through visual appearance (Experiment 2). Results showed a clear combinatory effect of person perception cues on joint attention (JA). Specifically, our results showed that age and sex cues interacted with social status information depending on the modality through which it was conveyed. In Experiment 3, we further investigated our results by testing whether the identities used in Experiments 1 and 2 triggered different pro-social behaviour. The results of Experiment 3 showed that the identities resulting as more distracting in Experiments 1 and 2 were also perceived as more in need and prompt helping behaviour. Taken together, our evidence shows a combinatorial effect of age, sex, and social status in modulating the gaze following behaviour, highlighting a complex and dynamic interplay between person categorization and joint attention. • Joint attention is modulated by person categorization cues. • Age and sex exert a combinatory effect on gaze following behaviour. • Social status interacts with age and sex depending on the way it is conveyed. • Identities perceived as more in need elicited larger gaze following behaviour.
