This database contains 162 gesture videos that have been rated for meaningfulness and given a one-word descriptor by 40 autistic and 40 non-autistic adults. Each video portrays an actor performing a different silent gesture. The gestures range from highly meaningful (e.g., iconic gestures) to ambiguous or meaningless. The gesture videos are silent and the face and mouth are obscured from view to allow other researchers the option of embedding audio. Videos are edited into precise 8.5 second clips, with each gesture beginning at 2.5 seconds and lasting 3.5 seconds.
The videos provided here are 720p high definition (HD) resolution which is a suitable size for small web content (e.g., use on a survey platform such as Qualtrics). Full HD resolution 1080p versions of the videos are available from the authors upon request.
Here we also provide the norming data and corresponding R scripts to calculate mean meaningfulness ratings; mean response diversity, entropy, and semantic similarity scores based off the participants' lemmatized one-word responses, age-of-acquisition ratings for lemmatized responses, and measures of visual variance* for the gesture videos.
Our manuscript, which details the procedure and results of the gesture stimuli norming process, is currently under revision for publication in Behavioral Research Methods.
*Per reviewer recommendations, we will be revisiting the measures of visual variance and plan to conduct additional analyses that may be better suited for quantifying the motion of our gesture stimuli.
