Overview and Meaning
Attend occurs within the context of search and exploration, and indicates the first time the animal locates a stimulus of potential interest. The animal will either approach and investigate the stimulus, or return to search.
The mouse, from a short distance away, will direct its attention towards a stimulus, indicated by pause in locomotion, and a fixation of the eyes and ears on the stimulus.
Exploration occurs in three main contexts, Social, Food, and Environmental. However, the context is not normally apparent until the investigation stage of the behavior chain.
