Cognitive psychology is meant to help us try to understand the human thought process and how we acquire, process, and store information. Professionals in this branch of psychology study a number of mental processes.
Chicken Oysters. Oysters are two small, round pieces of dark meat on the back of poultry near the thigh, in the hollow on the dorsal side of the ilium bone. Some regard the oyster meat to be the most flavorful and tender part of the bird, while others dislike the taste and texture.
Hoisin and Oyster sauces are traditional Chinese flavorings, and are both brown and viscous, but the similarities pretty much end there. Oyster sauce is briny and salty, Hoisin is sweet and made with dried fruits (plums I think). Hoisin and Oyster are about as interchangeable as ketchup and marinara sauce, or salsa.
