what is the difference between mannerism & stereotypy?

Answer 1

A mannersim is a particular pattern of socially-acceptable, situational behavior within a person. Someone, for example, may have a mannersim of being slow-walking, or in using their hands to express themself when they talk. Stereotypy is a compulsive, unconscious pattern of motor activity which is pervasive over every situation, such as head-shaking or hand-flapping. While a person who has a mannerism of using their hands when they talk will stop moving their hands when they are not speaking, a person who has the stereotypy expresed through hand-flapping will continue the behavior while sitting, walking, talking, etc. Also, stereotypy generally increases in intensity with stress, while a mannerism is usually stable.

Answer 2

I think mannerism pertains to someone's manners--in that they may have a special way of completing a task or follow the same routine. With stereotypy, the person repeatedly performs routine acts over and over.

Answer 3

These are medical terms with applications to child neurology. Definitions are as follows:

Stereotypy: “involuntary, patterned, coordinated, repetitive, rhythmic, and nonreflexive features, (which) typically last for seconds to minutes, tend to occur in clusters, appear many times per day, and are associated with periods of stress, excitement, fatigue, or boredom” and are readily suppressible (Mahone et al 2004).

Mannerism: Stereotypies must be distinguished from mannerisms, tics, and other complex repetitive acts. A mannerism is an odd, idiosyncratic METHOD OF PERFORMING A TASK that is unique to an individual and serves no apparent function (ie, a person who cocks an arm in a peculiar way in order to drink from a cup; a ballplayer who performs ritualistic acts "for luck.").

Note that stereotypies have no function/purpose while mannerisms are a purposeful movement.

Answer 4

This is only a guess but I think mannerism is a learned trait and stereotype is an inherited trait...Could be wrong...
