what is frustration explain the sources of frustration
Frustration In psychology, frustration is a common emotional response to opposition, related to anger, annoyance and disappointment, frustration arises from the perceived resistance to the fulfillment of an individual's will or goal[1] and is likely to increase when a will or goal is denied or blocked. There are two types of frustration; internal and external. Internal frustration may arise from challenges in fulfilling personal goals, desires, instinctual drives and needs, or dealing with perceived deficiencies, such as a lack of confidence or fear of social situations. Conflict, such as when one has competing goals that interfere with one another, can also be an internal source of frustration and can create cognitive dissonance. External causes of frustration involve conditions outside an individual's control, such as a physical roadblock, a difficult task, or the perception of wasting time.[2] There are multiple ways individuals cope with frustration such as passive–aggressive behavior, anger, or violence, although frustration may also propel positive processes via enhanced effort and strive.[3] This broad range of potential outcomes makes it difficult to identify the original cause(s) of frustration, as the responses may be indirect. However, a more direct and common response is a propensity towards aggression.[4]
Reinforcement Laboratory research on reinforcement is usually dated from the work of Edward Thorndike, known for his experiments with cats escaping from puzzle boxes.[10] A number of others continued this research, notably B.F. Skinner, who published his seminal work on the topic in The Behavior of Organisms, in 1938, and elaborated this research in many subsequent publications.[11] Notably Skinner argued that positive reinforcement is superior to punishment in shaping behavior.[12] Though punishment may seem just the opposite of reinforcement, Skinner claimed that they differ immensely, saying that positive reinforcement results in lasting behavioral modification (long-term) whereas punishment changes behavior only temporarily (short-term) and has many detrimental side-effects. A great many researchers subsequently expanded our understanding of reinforcement and challenged some of Skinner's conclusions. For example, Azrin and Holz defined punishment as a “consequence of behavior that reduces the future probability of that behavior,”[13] and some studies have shown that positive reinforcement and punishment are equally effective in modifying behavior. Research on the effects of positive reinforcement, negative reinforcement and punishment continue today as those concepts are fundamental to learning theory and apply to many practical applications of that theory.
