Classical Psychophysics
Discuss the "thresholds" theory of classical psychophysics and explain how characteristics of the perceiver are also important in determining the selection of stimuli.
The theory that our human cognitive ability has thresholds from the conscious level to a non-conscious level which varies over time in strength. These thresholds are physical and are not defined, but generally are from those activities and thoughts that are the most active having a threshold that defines our active consciousness, down to those thoughts that are several thresholds away and not seemingly linked to our current awareness. The concepts behind the theory attempt to bring together areas of knowledge, including the commonly-held beliefs about short-term memory being …show more content…
Whether people realize it or not, their memories define who they are. There are many areas of the brain that help you create and retrieve memories. Damage or malfunction of any of these areas can lead to memory loss. Memory loss due to problems with specific brain areas may be different. It may involve only memory of recent or new events, past or remote events, or both. The amnesia may be only for specific events or for all events. The problem may involve learning new information or forming new memories. Mental or thinking abilities may still be present or may have been lost. Filling in the details with imagined events (confabulation), and disorientation to time and place may occur. Memory loss may be for words and thoughts only, or for the body can no longer perform specific actions calls motor action. Memory loss may also be partial, meaning failing to remember only a selected group of …show more content…
Does someone view himself as a good person, worthy of good things? If he does, he probably has healthy self esteem. If an individual views himself as flawed and unworthy of praise or the respect of others, he probably has low self-esteem.
Self-esteem motivates people's actions as well as the decisions they make. Individuals with positive self-esteem are likely to believe that they measure up to others sufficiently. They are more likely to have the confidence to pursue different accomplishments, whether it is trying to do well on a test, trying out for a sports team, answering a question in class, or applying for a job. These individuals are not overly afraid of failure; they realize that failure is a natural part of life and whether they fail or succeed at something does not indicate their overall worth and ability as a
