clothes, pitch in voice, etc., when making a first impression. People have the tendency to judge others by associating certain facial features with specific personality types. For example, studies indicate that people are perceived as stronger, more assertive, and competent if they have small eyes, low eyebrows, an angular chin, wrinkled skin, and a small forehead. People tend to associate baby-faced people with impotence and harmlessness. Situations – context from prior experiences are able to easily predict the sequences or results of an event based on the extent and depth of their past experiences with a similar event. The ability to anticipate the outcomes of a situation is also greatly influenced by an individual's cultural background because this inevitably shapes the types of experiences. Situational observations either lead humans to have preset notions about certain events or to explain the causes of human behaviors. Behaviors – nonverbal communication Nonverbal communication helps people express their emotions, attitudes, and personalities. The most dominant form of nonverbal communication is the use of facial expressions to channel different emotions. Greatly influenced by Charles Darwin's research on facial expressions and book The Expression of the Emotions in Man and Animals (1872), it is believed that all humans, regardless of culture or race, encode and decode the six "primary" emotions, (happiness, sadness, anger, fear, surprise, and disgust), universally in the same way. To encode means to communicate nonverbal behavior, while to decode means to interpret the meaning or intention of the nonverbal behavior. Decoding sometimes is inaccurate due to affect blend, (a facial expression with two differently registered emotions), and/or display rules, (culturally dictated rules about which nonverbal behaviors are acceptable to display). Other nonverbal cues such as: body language, eye contact, and vocal intonations can affect social perception by allowing for thin-slicing. Thin-slicing describes the ability to make quick judgements from finding consistencies in events based only on narrow frames of experience. Attribution With the observations drawn from persons, situations, and behavior, the next step is to make inferences that identify an individual's inner dispositions. Attribution theories A large component of social perception is attribution. Attribution is the use of information gathered through observation to help individuals understand and rationalize the causes of one's own and others' behaviors. Psychological research on attribution began with the work of Fritz Heider in 1958, and was subsequently developed by others such as Harold Kelley and Bernard Weiner. People
