The Decay theory is a theory that proposes that memory fades due to the mere passage of time. Information is therefore less available for later retrieval as time passes and memory, as well as memory strength, wears away. [1] When an individual learns something new, a neurochemical "memory trace" is created.
Forgetting curve. The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [1] A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time ...
University of Breslau. University of Halle. Hermann Ebbinghaus (24 January 1850 – 26 February 1909) was a German psychologist who pioneered the experimental study of memory, and is known for his discovery of the forgetting curve and the spacing effect. He was also the first person to describe the learning curve.
Forgetting or disremembering is the apparent loss or modification of information already encoded and stored in an individual's short or long-term memory. It is a spontaneous or gradual process in which old memories are unable to be recalled from memory storage. Problems with remembering, learning and retaining new information are a few of the ...
The butterfly effect or sensitive dependence on initial conditions is the property of a dynamical system that, starting from any of various arbitrarily close alternative initial conditions on the attractor, the iterated points will become arbitrarily spread out from each other. Experimental demonstration of the butterfly effect with six ...
The Brown–Peterson task refers to two studies published in the late 1950s that used similar procedures, one in 1958 by John Brown [1] and a second in 1959 by Lloyd and Margaret Peterson. [2] The first experiment involved 24 psychology students at Indiana University at the time. The examiner proceeded by spelling a random three-letter nonsense ...
Approximate number system. Parallel individuation system. v. t. e. Overview of the forms and functions of memory. Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed. It is the retention of information over time for the purpose of influencing future action. [1]
Figure A: Normal Decay Figure B: Sleeper Effect. The sleeper effect is a psychological phenomenon that relates to persuasion. It is a delayed increase in the effect of a message that is accompanied by a discounting cue, typically being some negative connotation or lack of credibility in the message, while a positive message may evoke an immediate positive response which decays over time.
