Abstract copyright data collection owner.When we drop an object from our hands, we use internal models of both our body height and object-motion to predict when it will hit the floor. What happens if the sensory feedback finally received from the impact conflicts with this prediction? The study to which these data belongs shows that such conflict results in changes in the internal estimates of our body height: When the object people dropped takes longer than expected to hit the floor, they report feeling taller and behave as if their legs were longer. This provides the first evidence of cross-modal re-calibration of body-height representations as a function of changes in the distant environment. Crucially, the re-calibration results from a mismatch between the predicted and actual outcome of an action, the ball’s release and impact, which are causally-related but separated in space and time. These results suggest that implicit models of object-motion can interact with implicit and explicit models of one’s body height. The data in this collection are part of The Hearing Body project, a project investigating how the manipulation of action sounds may alter the mental representation of one's body and the related emotional state and body behavior. Other data collections part of The Hearing Body project have been deposited (see Related Resources). All parts 1 to 9 consist of experimental data, from different studies. Part 1, 2, 5, 7 and 9 contain subjective reports and behavioral data. Part 3 and 4 contain subjective reports, behavioral data and data on electrodermal activity changes. Part 6 contains subjective reports, behavioral data and data on muscle activity changes (EMG); Part 8 contains subjective reports, behavioral data and data on voice frequency changes.
The mental representation we have of our body is essential for successful interaction with the environment. This representation is not fixed, but is continuously updated in response to the available sensory information. While previous studies have highlighted the role of vision, touch and proprioception in constructing the body-representation in the brain, the role of auditory information remains largely unknown. Interestingly, the sounds that accompany almost every bodily movement are highly rich in information about the body and the space immediately surrounding it. For instance, the sounds produced when tapping on a surface inform us about the length and strength of our arm. This project will investigate how auditory information generated by our bodies updates our body-representation. A series of psychological experiments will explore how altering self-produced sounds in real-time changes different body-representations, including the representation of the space surrounding the body, the potential actions that we can perform and the emotional states linked to our body capabilities. This multidisciplinary and innovative research project will provide novel insights into the nature of body-representations and, ultimately, guide the design of audio-based applications that can improve body-image, self-esteem, movement patterns and social interactions to support wellbeing and rehabilitation for people with movement impairments.

|Method of data collection:||
The effects of auditory and tactile stimuli were evaluated by combining self-reporting (questionnaires) and objective measures. Objective measures included step sizes, and estimations of one's body height and leg length.
