This study investigated how museum visitors with very low or no vision perceived and processed tactile pictures and/or audio-descriptions of visual paintings. Two visual paintings were selected and a focus group was established ( N = 8). Qualitative interview and observation data were collected. This study found two types of museum visitors: those who explored the tactile picture first and those who rather listened to the audio-description. When exploring each element in the tactile picture, they all started by exploring the element’s global (shape) outline and, when struggling to recognise it, turned to the audio-description. They preferred the audio-description to start describing where their fingers were. Tactile texture attracted their attention, sparked their curiosity, and enabled them to create a mental image of the tactile picture, but also confused them. They preferred the global (element shape) outline to be straightened out, so that curves become angular, and texture only for targeting certain elements.

Lateralized Readiness Potentials

Lateralized readiness potentials (LRPs) were measured in left/right/no-go tasks using compound global/local stimuli. In Experiment 1, participants responded to local target shapes and ignored global ones. RTs were affected by the congruence of the global shape with the local one, and LRPs indicated that irrelevant global shapes activated the responses with which they were associated. In Experiment 2, participants responded to conjunctions of target shapes at both levels, withholding the response if a target appeared at only one level. Global shapes activated responses in no-go trials, but local shapes did not. The results are consistent with partial-output models in which preliminary information about global shape can partially activate responses that are inconsistent with the local shape. They also demonstrate that part of the global advantage arises early, before response activation begins and probably before recognition of the local shape.
