Supplementary information S2 (pdf): Additional analyses. from Gaze-contingent reinforcement learning reveals incentive value of social signals in young children and adults

The supplementary information S2 includes additional analyses investigating the initial exposure to both engaging and non-engaging cues, the proportion of looking time on the reward-predictive cue at pre-test and post-test, the side bias at pre-test and post- test, the children and adults’ impression of the task and the viewing time of the reward (cartoon)

Supplementary information S1 (video): Visualization of the task. from Gaze-contingent reinforcement learning reveals incentive value of social signals in young children and adults

The supplementary information S1 includes a video displaying the task in the four different conditions investigated in the study (social and engaging reward predictive cue; social and non-engaging reward predictive cue; non-social and engaging reward predictive cue and non-social and non-engaging reward predictive cue)

Mean foveation probability as a function of the viewing + inference condition (the No-context + No-inference [blue], No-context + Inference [red] and Context + Inference [green], Shuffled Baseline [black] conditions) and Shot (1–6).

<p>Error bars represent the standard error.</p

Similarity in gaze distribution as a function of the viewing condition + inference group (the No-context + No-inference [blue], No-context + Inference [red] and Context + Inference [green] conditions) and Shot (1–6).

<p>Similarity is expressed as z-scored probabilities relative to the Context + Inference baseline gaze probability distribution. Larger values indicate greater attentional synchrony, while lower values indicate less attentional synchrony.</p

Similarity in gaze distribution as a function of viewing condition + inference group (No-context + No-inference [blue], No-context + Inference [red] and Context + Inference [green], Shuffled Baseline [black] conditions) and Shot (1–6).

<p>Gaze similarity is calculated relative to the Context + Inference group. Similarity is expressed as z-scored probabilities relative to the mean Context + Inference group gaze probability distribution. Values below zero indicate less attentional synchrony than the mean for the Context + Inference group; values above zero indicate higher attentional synchrony than the mean. Error bars indicate +/- 1 standard error across individuals for each frame.</p

Percentage of participants who perceived new events in Shots 1–6 in the Context and No-context viewing conditions.

<p>Percentage of participants who perceived new events in Shots 1–6 in the Context and No-context viewing conditions.</p

Each graph represents the proportion of participants who reported a critical idea over Shots 4–6 in the Context and No-context viewing conditions.
