What are the most influential studies on the function of memory?
Below we take a look at some of the most influential studies, experiments and theories that continue to guide our understanding of the function of the human memory. 1. Multi-Store Model (Atkinson & Shiffrin, 1968)
What does a prospective memory study measure?
In general, prospective memory studies measure reaction times and accuracy of completing certain simple tasks. At the outset of the study, participants are told that a special event may occur during the task and they are to respond accordingly.
How has the study of memory changed over the years?
The change in the overall study of memory during the 1950s and 1960s has come to be known as the “cognitive revolution”, and led to several new theories on how to view memory, and yielded influential books by George Miller, Eugene Galanter, Karl Pribram, George Sperling and Ulric Neisser.
Who was the first person to develop memory?
Roman rhetoricians such as Cicero and Quintillian expanded on the art of memory or the method of loci (a method often first attributed to Simonides of Creos or the Pythagoreans), and their ideas were passed down to the medieval Scholastics and later scholars of the Renaissance like Matteo Ricci and Giordano Bruno.
Who studied memory?
Hermann EbbinghausHermann Ebbinghaus (1850–1909) Hermann Ebbinghaus was a German psychologist and philosopher who pioneered the scientific study of memory. Until Ebbinghaus published his book (1885/1964), experimental psychology had confined itself to exploring the nature of sensation and perception.
Why do cognitive psychologists study memory?
Findings from cognitive psychology help us understand how people think, including how they acquire and store memories. By knowing more about how these processes work, psychologists can develop new ways of helping people with cognitive problems.
What is a memory study?
Memory studies is an academic field studying the use of memory as a tool for remembering the past. It emerged as a new and different way for scholars to think about past events at the end of the 20th century.
What is memory research in psychology?
A large part of the research on memory is based on experiments conducted in laboratories. Those who take part in the experiments - the participants - are asked to perform tasks such as recalling lists of words and numbers. Both the setting - the laboratory - and the tasks are a long way from everyday life.
What would a cognitive psychologist do?
Cognitive psychologists develop strategies to help people who are experiencing difficulties with one or more of these processes. They work with individuals with Alzheimer's disease, brain trauma, learning disabilities, and developmental disorders such as autism.
What is memory neuroscience?
Memories are made by changes in collections of neurons and the connections or synapses between them. A memory may be laid down in one group of neural circuits, but recalled in another. Each time we recall a memory it may change depending on the neural circuits that are engaged at that particular moment.
What is the study of psychology called?
Psychology is the scientific study of the mind and behavior. Psychologists are actively involved in studying and understanding mental processes, brain functions, and behavior.
How do we research memory?
The study of memory incorporates research methodologies from neuropsychology, human development and animal testing using a wide range of species. The complex phenomenon of memory is explored by combining evidence from many areas of research.
What is studied in cognitive psychology?
Cognitive Psychology Explores Our Mental Processes Cognitive psychologists, sometimes called brain scientists, study how the human brain works — how we think, remember and learn. They apply psychological science to understand how we perceive events and make decisions.
What psychologist is best associated with studying the function of memory?
Which of the following psychologists is best associated with studying the function of memory? Hermann Ebbinghaus studied memory by memorizing nonsense syllables and seeing how many he could remember.
What are the 3 theories of memory?
These are— An encoding process, a storage process and a retrieval process.
Who are the major psychological researchers involved in memory studies?
An influential theory of memory known as the multi-store model was proposed by Richard Atkinson and Richard Shiffrin in 1968.

What do cognitive psychologists study quizlet?
What is cognitive psychology? A branch of psychology concerned with the scientific study of the mind - that includes such mental processes as perception, attention, memory, language, problem solving, etc.
What is studied in cognitive psychology?
Cognitive Psychology Explores Our Mental Processes Cognitive psychologists, sometimes called brain scientists, study how the human brain works — how we think, remember and learn. They apply psychological science to understand how we perceive events and make decisions.
What is the main emphasis of cognitive psychology?
Cognitive Psychology is the science of how we think. It's concerned with our inner mental processes such as attention, perception, memory, action planning, and language. Each of these components are pivotal in forming who we are and how we behave.
What is the theory of memory?
This model suggested that information exists in one of 3 states of memory: the sensory, short-term and long-term stores. Information passes from one stage to the next the more we rehearse it in our minds, but can fade away if we do not pay enough attention to it.
What information is important to reach long term memory?
Key information regarding people that we have met, important life events and other important facts makes it through the sensory and short-term memory stores to reach the long-term memory.
Why are trigrams used in research?
The use of such trigrams makes it impracticable for participants to assign meaning to the data to help encode them more easily, while the interference task prevented rehearsal, enabling the researchers to measure the duration of short-term memories more accurately.
How many chunks of information can a person hold?
In a renowned 1956 paper published in the journal Psychological Review, Miller cited the results of previous memory experiments, concluding that people tend only to be able to hold, on average, 7 chunks of information (plus or minus two) in the short-term memory before needing to further process them for longer storage.
What is short term memory?
The short-term memory gives us access to information that is salient to our current situation, but is limited in its capacity.
Why do animals have the ability to remember smells?
The ability to remember and later recognize smells enables animals to detect the nearby presence of members of the same group, potential prey and predators. But how has this evolutionary advantage survived in modern-day humans?
How does information enter the memory?
Information enters the memory from the senses - for instance, the eyes observe a picture, olfactory receptors in the nose might smell coffee or we might hear a piece of music. This stream of information is held in the sensory memory store, and because it consists of a huge amount of data describing our surroundings, we only need to remember a small portion of it. As a result, most sensory information ‘ decays ’ and is forgotten after a short period of time. A sight or sound that we might find interesting captures our attention, and our contemplation of this information - known as rehearsal - leads to the data being promoted to the short-term memory store, where it will be held for a few hours or even days in case we need access to it.
Can memories be modified?
Although researchers know that memories can be modified when they are retrieved, less is known about how the properties of reactivation affect memory. Researchers sent participants on a self-guided tour of a museum with a camera that automatically took pictures of their visit.
Is memory accuracy higher on retrocue trials?
Memory accuracy was significantly higher on trials with the valid retro-cue. The authors suggest that selective attention during the maintenance of a memory can turn it from one that is relatively weak into one that is more robust, which allows for access to information that would otherwise be forgotten.
What is the significance of prospective memory studies?
An important implication of prospective memory studies is that they deal with our ability to accomplish a future intention – in other words, achieve a goal. The signs, reminders, or mnemonic devices that help you remember not to forget a future intention, are also those cues that will help you achieve your goals.
What is prospective memory?
In general, prospective memory studies measure reaction times and accuracy of completing certain simple tasks. At the outset of the study, participants are told that a special event may occur during the task and they are to respond accordingly. The special event Is the prospective memory cue. Source: neil Farber.
What are the different types of prospective memories?
As with retrospective memory, several types of prospective memories exist. Prospective memory is divided into time -, event - and activity-based memories. While some have proposed that these differences represent unique modalities of memory, Brewer has provided evidence that these divisions are actually based on the individual cues used to trigger a recall. For example, time-based prospective memories are triggered by a time-cue, such as stopping at the grocery store (action) at 4pm (time). Event-based memories are intentions triggered by cues such as remembering to stop at the grocery store (action) after seeing the string (event) tied around my wrist. Activity-based memories are intentions triggered by cues like remembering to stop (action) at the grocery store during the drive (activity) home from work. Do you use post it notes, lists, strings tied around your finger, or knotted handkerchiefs to remind you to do something or go somewhere in the future?
What is episodic memory?
Episodic memory is the collection of personal past experiences that occurred at a particular time and place. Episodic memory is an essential component in stimulating potential future contexts to enhance prospective memory. Autobiographical events including time, place and emotions play a vital role in your ability to effectively plan and achieve goals in the future. It’s easy to understand how your emotional state and preconceived notions may cloud memories of past events. Well it’s also true that emotions may also significantly impair or enhance your ability to remember future plans.
What is the process by which information and data is encoded, stored and retrieved?
Memory is the process by which information and data is encoded, stored and retrieved. "What did I eat for breakfast this morning?" "Where did I leave my car keys?" "Who is buried in Grant’s Tomb?" "What was your name again?"
Is memory a method of recalling past events?
We often think about memory as a method of recalling past events. But memory isn’t just about the past. We also need to not forget about the future. Unfortunately, most of us will not remember something that’s happened in the future (like Michael J. Fox in Back to the Future). However, much of our lives involve planning ...
Who has developed Towards a dementia plan?
WHO has developed Towards a dementia plan: a WHO guide plan: a WHO guide , which provides guidance to Member States in creating and operationalizing a dementia plan. The guide is closely linked to WHO’s GDO and includes associated tools such as a checklist to guide the preparation, development and implementation of a dementia plan. It can also be used for stakeholder mapping and priority setting.
What is dementia in psychology?
Dementia is a syndrome – usually of a chronic or progressive nature – that leads to deterioration in cognitive function (i.e. the ability to process thought) beyond what might be expected from the usual consequences of biological ageing. It affects memory, thinking, orientation, comprehension, calculation, learning capacity, language, and judgement. Consciousness is not affected. The impairment in cognitive function is commonly accompanied, and occasionally preceded, by changes in mood, emotional control, behaviour, or motivation.
What Type Of Doctor Do I See For Memory Loss?
The type of doctor you see for memory loss is usually your general practitioner. Your doctor will ask some questions to evaluate if there is or is not a problem. It’s helpful for a lot of people to have a friend or family member along to offer insight as an observer.
Is memory loss reversible?
There are some fairly common memory loss causes that are reversible. While a person might exhibit dementia like symptoms, they are not a definitive sign that there is Alzheimer’s.
Is it normal to have memory loss?
It’s normal as we age to have some memory loss that doesn’t affect quality of life. We often can’t remember a name but recall it later. Or we misplace our keys and find them after some searching. These are the types of memory challenges most of us face and can be managed with lists and habits such as key hooks.
Multi-Store Model
- An influential theory of memory known as the multi-store model was proposed by Richard Atkinson and Richard Shiffrin in 1968. This model suggested that information exists in one of 3 states of memory: the sensory, short-term and long-term stores. Information passes from one stage to the next the more we rehearseit in our minds, but can fade away if...
Levels of Processing
- Fergus Craik and Robert Lockhart were critical of explanation for memory provided by the multi-store model, so in 1972 they proposed an alternative explanation known as the levels of processing effect. According to this model, memories do not reside in 3 stores; instead, the strength of a memory trace depends upon the quality of processing, or rehearsal, of a stimulus. I…
Working Memory Model
- Whilst the Multi-Store Model (see above) provided a compelling insight into how sensory information is filtered and made available for recall according to its importance to us, Alan Baddeley and Graham Hitch viewed the short-term memory (STM) store as being over-simplistic and proposed a working memory model(Baddeley & Hitch, 1974), which replace the STM. The w…
Miller’s Magic Number
- Prior to the working memory model, U.S. cognitive psychologist George A. Miller questioned the limits of the short-term memory’s capacity. In a renowned 1956 paper published in the journal Psychological Review, Miller cited the results of previous memory experiments, concluding that people tend only to be able to hold, on average, 7 chunks of information (plus or minus two) in th…
Memory Decay
- Following Miller’s ‘magic number’ paper regarding the capacity of the short-term memory, Peterson and Peterson set out to measure memories’ longevity - how long will a memory last without being rehearsed before it is forgotten completely? In an experiment employing a Brown-Peterson task, participants were given a list of trigrams - meaningless lists of 3 letters (e.g. GRT…
Flashbulb Memories
- There are particular moments in living history that vast numbers of people seem to hold vivid recollections of. You will likely be able to recall such an event that you hold unusually detailed memories of yourself. When many people learned that JFK, Elvis Presley or Princess Diana died, or they heard of the terrorist attacks taking place in New York City in 2001, a detailed memory se…
Memory and Smell
- The link between memory and sense of smell helps many species - not just humans - to survive. The ability to remember and later recognize smells enables animals to detect the nearby presence of members of the same group, potential prey and predators. But how has this evolutionary advantage survived in modern-day humans? Researchers at the University of North Carolina test…
interference
- Interference theory postulates that we forget memories due to other memories interferingwith our recall. Interference can be either retroactive or proactive: new information can interfere with older memories (retroactive interference), whilst information we already know can affect our ability to memorize new information (proactive interference). Both types of interference are more likely t…
False Memories
- Can false memories be implanted in our minds? The idea may sound like the basis of a dystopian science fiction story, but evidence suggest that memories that we already hold can be manipulated long after their encoding. Moreover, we can even be coerced into believing invented accounts of events to be true, creating false memoriesthat we then accept as our own. Cognitiv…
The Weapon Effect on Eyewitness Testimonies
- A person’s ability to memorize an event inevitably depends not just on rehearsal but also on the attention paid to it at the time it occurred. In a situation such as an bank robbery, you may have other things on your mind besides memorizing the appearance of the perpetrator. But witness’s ability to produce a testimony can sometimes be affected by whether or not a gun was involved i…
