    Abstract

    We present the use of two game-like tasks, Catnip and Dinorun, to explore affective responses to volitional control perturbations. We analyze behavioral and physiological measures with the self-assessment manikin (SAM), pupillometry, and electroencephalography (EEG) responses to provide intratrial emotional state as well as inter-trial correlates with selfreported survey responses. We find that subject gameplay characteristics significantly correlate with valence and dominance scores for both games, and that perturbations to the games produce a measurable decrease in response scores for Dinorun. During perturbation events, pupillometry analysis reveals considerable SAM-agnostic dilation, with stronger responses in more rigid trialized event structures. Furthermore, analyses of neural activity from central and parietal regions demonstrate significant measurable evoked responses to perturbed events across the majority of subjects for both games. By introducing perturbations, this set of experiments and analyses inform and enable further studies of affective responses to the loss of volitional control during engaging, game-like tasks.
