In recent years, studies dealing with temperature regulation,
temperature sensitivity, and physiological responses to temperature
in lizards and other reptiles have increased tremendously. It is
notable that snakes have been largely ignored in such studies. This
no doubt is due to their less direct relationship to ancestral endotherms.
However, problems...
Behavioral studies have observed facial recognition bypass attentional limitations when performed with non-facial recognition tasks (e.g., a digit task). Awh et al. (2004) proposed this was due to multi-channel processing, where non-facial objects utilize a feature-based channel leaving the configural-based channel available for facial processing. We tested this hypothesis using...
Throughout history, there have been many examples of political figures who have influenced fashion: from Theodore Roosevelt to Jacqueline Kennedy to Michelle Obama.
