It involves a checkerboard pattern that lies flush under a Plexiglas surface for half of its length, but then slants some four feet, creating the illusion of a sheer drop beneath the solid surface.#2 The infant’s cry is pitched in such a way to get the attention of the adult brain. It is also the most effective way of distracting participants so that they can’t even perform the simplest of subtraction tasks.#3 Babies are hardwired to need their mothers’ attention and love, but they also come equipped with behaviors that make it hard for their mothers to ignore them. This is why, if your connection to your mother has been fraught, difficult, or even damaging, a very big part of you still wants and needs her love.#4 The Strange Situation is a series of staged encounters with the mother and child coming into the unfamiliar lab room. The mother would sit back as the child played and explored the room. Then a stranger would enter, speak to the mother, and approach the infant; while the baby was distracted, the mother would leave the room.
