Efficiency is productive because people can make judgments quickly and keep things simple. The disadvantage is that errors occur in these judgments. Selectivity is NOT particularly productive because people are likely to interpret what they see in a way that fits their expectations. If their expectations are negative, so will be the believed results. Also, behavior may be missed because people's interpretations are incorrect.
Stability is found in most people's impressions.
First impressions are powerful because they are caused by the fact that people see what they expect to see. A primacy effect occurs when initial information carries more weight than subsequent information. And, confirmatory biases may lead people to discount later information that contradicts their initial impression. Define stereotypes and give three reasons why they persist. Stereotypes are widely held beliefs that people have certain characteristics simply because of their membership in a particular group.
