The term reparation was used by Melanie Klein (1921) to indicate a psychological process of making mental repairs to a damaged internal world. [1] In object relations theory, it represents a key part of the movement from the paranoid-schizoid position to the depressive position — the pain of the latter helping to fuel the urge to reparation.
The sensory enhancement theory assumes that attentional resources will spread until they reach the boundaries of a cued object, [1] [2] including regions that may be obstructed or are overlapping other objects. [3] [4] It has been suggested that sensory enhancement is an essential mechanism that underlies object-based attention.
Psychology Today is an American media organization with a focus on psychology and human behavior. The publication began as a bimonthly magazine, which first appeared in 1967. The print magazine's reported circulation is 275,000 as of 2023. [ 2 ]
t 1 and t 2 are times when the impulse begins and ends, respectively, m is the mass of the object, v 2 is the final velocity of the object at the end of the time interval, and; v 1 is the initial velocity of the object when the time interval begins. Impulse has the same units and dimensions (MLT −1) as momentum.
The motion direction of a contour is ambiguous, because the motion component parallel to the line cannot be inferred based on the visual input. This means that a variety of contours of different orientations moving at different speeds can cause identical responses in a motion sensitive neuron in the visual system.
In other words, upon viewing an object getting progressively lighter and asked to remember the final shade, participants accept a darker version of the object (where a representational momentum parallel would be to accept a lighter shade). One suggestion for this difference is that memory is playing more of a role in determining color. [22]
Freud's theory of psychosexual development is represented amongst five stages. According to Freud, each stage occurs within a specific time frame of one's life. If one becomes fixated in any of the five stages, he or she will develop personality traits that coincide with the specific stage and its focus.
An impulse is a wish or urge, particularly a sudden one. It can be considered as a normal and fundamental part of human thought processes, but also one that can become problematic, as in a condition like obsessive-compulsive disorder, [24] [unreliable medical source?] borderline personality disorder, attention deficit hyperactivity disorder, or in fetal alcohol spectrum disorders.
