paper one cognition and behavior topic one memory episodic memory semantic memory and procedural memory are the three primary types of memory these types of memory are used to make up long-term memory
Episodic memory
A type of long-term memory that involves the ability to recall specific events experiences and situations from our past
Episodic memory
Holidays
Autobiographical memory
Semantic memory
Our general knowledge and understanding of the world, involving the ability to recall facts Concepts and ideas that are not tied to a specific event or experience
Semantic memory
Knowing the sky is blue
Understanding the meaning of words
Knowing historical events
Procedural memory
Our ability to learn and remember how to perform various motor skills and actions, often referred to as muscle memory
Procedural memory
Riding a bike
Typing on a keyboard
Playing a musical instrument
Encoding and storage of memories
1. Encoding: Transforming sensory input into a form that can be stored in the brain
2. Storage: Memories stored in different regions of the brain depending on the type of memory
3. Retrieval: Accessing stored memories by reactivating the neural code
Multi-store model of memory
Consists of three separate stores: Sensory register, Short-term memory, Long-term memory
Information passes through each store in a linear fashion
Sensory register
First stage of memory processing, involves immediate and automatic recording of sensory information from the environment
Short-term memory
Second stage of memory processing, involves temporary storage of information that is currently being attended to or actively processed
Long-term memory
Final stage of memory processing, involves storage of information that has been rehearsed or processed in short-term memory
Sensory register features
Coding: Information represented in the same form as received from the environment
Capacity: Very large, can hold vast amount of sensory information
Duration: Very short, a few hundred milliseconds to a few seconds
Short-term memory features
Coding: Primarily encoded in the form of sound or speech-based representations
Capacity: Limited, about 7 plus or minus 2 items
Duration: Relatively short, 20 to 30 seconds unless rehearsed
Long-term memory features
Coding: Encoded in various forms including semantic, visual, and acoustic
Capacity: Believed to be unlimited
Duration: Believed to be unlimited, some memories last a lifetime
Serial position effect
Tendency for people to remember items at the beginning and end of a sequence better than items in the middle
Primacy effect
Superior recall of items that appear at the beginning of a list
Recency effect
Superior recall of items that appear at the end of a list
The Primacy effect is explained by the idea that the first few items in the list were more likely to be transferred into long-term memory due to their extended rehearsal time
The Recency effect is explained by the fact that the last few items were still fresh in the participants' short-term memory when they were asked to recall them
Strengths of Murdoch's study
Conducted in laboratory conditions, establishing cause and effect
Supported by research with amnesiacs, showing Primacy effect is linked to long-term memory
Limitation of Murdoch's study
Artificial task of learning a list of words, not meaningful information
Reconstructive memory
Memory is not an exact recording of past events, but a construction based on our previous experiences, beliefs, and knowledge
Effort after meaning
People's natural tendency to try and make sense of new information and integrate it with their existing knowledge and beliefs
Schema
Mental framework or organizational structure that helps us process and remember information
Bartlett's study demonstrated the importance of schema in memory recall and provided evidence for the idea that memory is a constructive process influenced by pre-existing knowledge, beliefs, and cultural background
Interference
New information interferes with the ability to recall previously learned information, including proactive interference and retroactive interference
Context
Contextual cues can affect the accuracy of memory, as memories may be easier to recall in the same physical or emotional state as when they were encoded
False memories
Occur when an individual recalls something that did not actually happen or remembers an event differently from how it occurred, influenced by factors like leading suggestions, suggestive language, and incorporation of misinformation
Sensation refers to the process of receiving and detecting sensory input from the environment through our sensory organs, while perception involves the higher-level cognitive processes of organizing and interpreting sensory information
Monocular depth cues
Visual cues that help us perceive depth and distance using only one eye, including height in plane, relative size, and occlusion
Sensation and perception
An area of discussion in psychology as to whether there is a difference between the two
Monocular depth cues
Visual cues that help us perceive depth and distance using only one eye
Include height in plane, relative size, occlusion, and linear perspective
Height in plane
The placement of objects in a scene in relation to the horizon or ground, with objects higher in the visual field perceived as farther away and those lower as closer
Relative size
Using the size of familiar objects as a reference to determine their distance, with objects appearing smaller perceived as farther away and those appearing larger as closer
Occlusion
Using overlapping objects to determine their relative distance, with the covered object perceived as farther away than the object covering it
Linear perspective
The way parallel lines appear to converge in the distance, providing cues about the distance and depth of a scene
Binocular depth cues
Visual cues that rely on the coordination of both eyes and enable us to perceive depth and distance in three-dimensional space
Include retinal disparity and convergence
Retinal disparity
The slight difference in the image received by each eye due to their slightly different perspectives, which the brain combines to create a single three-dimensional image
Convergence
The inward movement of the eyes when focusing on nearby objects, which the brain uses to estimate the distance of an object
