Exam 2 Flashcards
Echoic memory
The brief memory of something a person just heard.
The three processes of memory:
Storage, Encoding, Retrieval
Iconic memory
Visual sensory memory lasting only a fraction of a second.
Short-term memory (STM)
The memory system in which information is held for brief periods of time while being used
Long-term memory (LTM)
The system of memory into which all the information is placed to be kept more or less permanently.
Levels-of-processing model
Model of memory that assumes information that is more “deeply processed,” or processed according to it’s meaning rather than just the sound or physical characteristics of the word or words, will be remembered more efficiently and for a longer period of time.
Parallel distributed processing model (PDP)
A model of memory in which memory processes are proposed to take place at the same time over a large network of neural connections.
Information processing model
The model of memory that assumes the processing of information for memory storage is similar to the way a computer processes memory in a series of three stages. The process of Encoding, Storage, and Retrieval are part of this model.
Working memory
An active system that processes the information in short term memory.
Serial position effect
Information at the beginning and end of a list, such as a song or a poem tends to be remembered more easily and accurately.
Sleep waves:
• Beta • Theta • Alpha • Delta
Beta
The brainwaves a person has when they are wide awake and mentally active.
Theta
Brainwaves indicating the early stages of sleep.
Alpha
Brainwaves that indicate a state of relaxation or light sleep.
Delta
Long, slow waves that indicated the deepest stage of sleep.
REM rebound
An increased amount of REM sleep after being deprived of REM sleep on earlier nights.
REM behavior disorder
A rare disorder in which the mechanism that blocks the movement of the voluntary muscles fails, allowing the person to thrash around an even get up and act out nightmares.
REM paralysis
The inability of the voluntary muscles to move during REM sleep.
Problem Solving
Process of cognition that occurs when a goal must be reached by thinking and behaving in certain ways.
Heuristics
An educated guess based on prior experience that helps narrow down the possible solutions for a problem. AKA a “rule of thumb.”
Prototypes
An example of a concept that closely matches the defining characteristics of a concept.
Availability heuristic
Estimating the frequency or likelihood of an event based on how easy it is to recall relevant information from memory or how easy it is for us to think of related examples.
Means-end analysis
Heuristic in which the difference between the starting situation and the goal is determined and then steps are taken to reduce that difference.
Mental sets
The tendency for people to persist in using problem-solving patterns that have worked for them in the past.
