episodic memory mcat

This is an example of prospective memory. It is a condition that is most commonly caused by heavy, constant alcohol abuse. Broca's area: responsible for forming speech. Semantic encoding involves encoding sensory information with specific relevance to the person (a phrase, word, image, event, etc.) Example: You have learned that UV rays from the sun can give you skin cancer, so when the sunlight becomes intense, you move to sit in the shade. The primacy effect is a phenomenon in which we are more likely to recall information that was listed in the beginning (as opposed to information mentioned in the middle of a list. Throughout someone's lifetime his or her brain is constantly changing. This phenomenon is called the misinformation effect. Psychological dependence occurs when the drug user is dependent on their drug(s) of choice to avoid painful emotions and memories. For instance, semantic memory might contain information about what a cat is, whereas episodic memory might contain a specific memory of petting a particular cat. This thread is archived. It is theorized that addiction is reinforced by the release of dopamine in circuits located in the brainstem (especially the nucleus accumbens, the pleasure center of the brain). Traditional list-learning memory experiments make it obvious when to store and retrieve memories, but it is less obvious when to do this in naturalistic settings. We use our echoic memory to recall the auditory information that has been stored. Example: if you heard a song in the car that you wanted to remember for later, you would come up with retrieval cues, such as which radio channel it was on, who you were listening to the music with, if the vocalist was female or male, etc. Tactile encoding involves the use of our tactile senses. Interpersonal Intelligence- the ability to understand and associate with other people. Acronyms are words or short sentences that represent a larger idea. For example, if you were to say, "My birthday is coming up!" Two main theories. Alzheimers is a degenerative disease, and can worsen to the point of physically disabling a patient. Created by. I'm a psychology and neuroscience major and worked at a memory clinic which is why I'm pretty knowledgeable on this particular topic. Componential intelligence- (also known as analytical intelligence) the traditional idea of intelligence. Cued recall is the ability to remember something once cued or asked. Memories are usually more accurate if the person can remember the source of their information. ; Implicit memory is a type of memory in which previous experiences aid the performance of a task without conscious awareness of these previous experiences. Electroencephalogram (EEG)- measures the electrical impulses of the brain, these high frequencies and low amplitudes are known as alpha waves (collectively referred to as neural synchrony). Acoustic encoding involves encoding sounds (language, music, other sounds). During this stage of non-REM (rapid eye movement) stage of sleep there are slow eye movements. Physiological dependence occurs when the user's body becomes so accustomed to having the drug that when the user stops they experience withdrawal. Episodic memory must … code spatiotemporal relations: The What-Where-When test. False information can make people prone to forming false memories. Amnesia refers to partial or complete inability to remember something. Symptoms include forgetfulness (common first symptom), changes in mood and behavior, and difficulty speaking and swallowing. Narcolepsy is a condition in which someone will fall asleep somewhat randomly, but especially when the person is relaxed. The first tests to measure intelligence were created to measure a "mental age", marked by a collection of abilities/disabilities that children of a certain age group possess. Nurture: the environmental influence such as social culture and education. Withdrawal refers to uncomfortable feelings such as fatigue, nausea, irritability, and headache once the drug has been stopped. Mindfulness-based stress reduction (MBSR) is a program based on the management of stress. Your memories of all those specific events and experiences are examples of episodic memory. These connections between neurons are called synapses. An example of positive transfer would be learning how to scramble eggs after already knowing how to make sunny side-up eggs. Episodic memories have a sort of emotional aspect to them which the constantly rehearsed facts lack. This is how the information is presented (ie. Here, we review evidence supporting the alternative perspective that episodic memory has a long evolutionary history. Episodic memory: a kind of explicit memory, that includes specific events/episodes Implicit memory: long-term memories that are not consciously remembered, including procedural memories and emotional conditioning (Occurs more in obese people). The #1 social media platform for MCAT advice. These would in fact be considered sematic. This means one's memory becomes skewed in a certain direction according to that person's mood. Another technique for memorization is to create hierarchies. Posted by u/[deleted] 1 year ago. Triarchic Theory of Intelligence -Developed by Robert Sternberg, 3 components. Emotional Intelligence is a type of intelligence that refers to one's ability to understand, sympathize/empathize, regulate, and express one's emotions. It can be caused by chronic stress, and is often treated by sleeping pills. Example of a parasomnia is somnambulism, popularly referred to as "sleep walking", as well as night terrors. Drug addiction is a disease in which people feel an excessive, constant compulsion to use drugs. This technique is especially effective if you can link new information to images or ideas that are personally applicable. The things we learn from what we observe in our environment shapes how we behave and think. The program includes various activities that focus on mindfulness, such as yoga and meditation, Depressants (e.g. Conclusions. Learn about the information processing model of human memory. Various associations connect nodes. This adaption is most active during the early stages of development. A schema is the overall framework of how we remember something (structure and components of the situation, details, etc.). This condition often involves a form of mental retardation, such as autism. It has been shown that information that is processed on a deeper level (such as information that is personally relatable) is more likely to be remembered. For example, if someone who hadn't played the piano in twenty years were to sit down and try to play the piano, they would likely have to relearn how to play. If this area is damaged, the person can speak fluently, but the words are gibberish. Episodic Memory + Semantic Memory = Declarative Memory Episodic memory and semantic memory together makeup part of your long-term memory and are known as declarative memory. Availability heuristic- tendency to believe that something is more common or more likely to happen just because it is more readily obtainable in our memory. Experiential intelligence- (also known as creative intelligence) the ability to familiarize oneself with new circumstances and form new concepts. Located in the left temporal lobe, in the posterior part of the superior temporal gyrus. As we become older, we are much more likely to struggle with free recall (recalling information "out of the blue") than with recognition. To recall something is to recover information without being given any clues. semantic memory (also known as explicit and declarative), procedural memory (also known as implicit memory), and episodic memory. Often times the user has been subjected to emotional and/or physical trauma in the past. During this period of time the child is very egocentric, and do not understand other people's perspectives. Someone with this syndrome does not feel sleep deprived, and is able to function normally. Echoic memory- the memory of a sound (very brief, lasting only as long as about 4 seconds). Interference is a phenomenon that occurs when one memory interferes with the creation of another memory, preventing it from forming. Dialectic behavioral therapy (DBT) is a type of cognitive behavioral therapy (CBT). The MCAT (Medical College Admission Test) is offered by the AAMC and is a required exam for admission to medical schools in the USA and Canada. This cumulative effect is known as summation. It is thought to work by blocking information being received by sensory neurons. How much our attention is divided depends on the difficulty of the tasks. This effect is known as depth of processing. IQ Scores: The average score on an intelligence test is 100. This is because cakes are typically more representative of a birthday than a salad. Intelligence is hard to measure; many of the tests administered to quantify intelligence have built-in bias, and have unavoidable confounding factors. It is characterized by the presence of delta waves. Others believe that linguistic development is dependent on usage and experience (Interactionist). For example, the color of a stranger's eyes. When the source of information is forgotten, this mistake is known as a source monitoring error. For example, one would exercise procedural memory when driving a car. Spell. Elaboration involves the relation of new information to old, long-term memories, to form a sort of narrative. The MCAT (Medical College Admission Test) is offered by the AAMC and is a required exam for admission to medical schools in the USA and Canada. It can be caused by an injury or disease of the brain; it is not contagious. Map expansion- information processing of a particular region of the brain can be heightened by frequent exposure to stimulus/ new information. If our prefrontal cortex suffered an injury, we would still be able to learn new things but it would all be done in a disorganized manner. There are three stages of memory: 1) Sensory memory 2) Short-term memory 3) Long-term memory. IQ tests). Used to help people recall old memories, though sometimes accidentally inaccurate, Scientists have observed measurable changes in brain activity during hypnotism. Some memories are emotionally biased. During this stage of sleep there is no eye movement, and growth hormones are secreted. save hide report. For example, in order to remember the order of operations (in mathematics) you could use the acronym PEMDAS (Parenthesis, Exponents, Multiply, Divide, Add, Subtract). DBT teaches a number of behavioral skills such as emotional regulation, mindfulness, and distress tolerance. The semantic buffer does not exist in his model, and is the correct answer. Delta waves are low frequency (0.5-3 Hertz) but high in amplitude. Trial and error - the process by which we experiment using various different approaches until we find one that is effective. There is also a pathway that leads back (from the hippocampus) to different areas of the primary cortex. Press J to jump to the feed. Hypnosis cannot cause someone to acquire extraordinary capabilities or to commit acts that go strongly against their morals (e.g. Few studies have examined both episodic and semantic autobiographical memory (AM) performance during late childhood and early adolescence. Heuristics, or mental shortcuts, are used so that we can make quick decisions. Nodes are what we call the specific ideas/ events that we remember. Everyone else in this thread is crazy imo, New comments cannot be posted and votes cannot be cast. For example, if someone is unhappy, this emotion may remind the person of other things/times that were unhappy as well. For example, if your dog has an accident in the house, you may remember your dog as a pain, when normally you love your dog. The ability to form and recall accurate memories can be negatively affected by afflictions such as depression, trauma, brain injuries, and high levels of stress. Lorazepam, Clonazepam, Xanax, Valium), Prescribed to alleviate excessive anxiety, Stimulates GABA system, creates feeling of calm, Hallucinogens (e.g. Retrospective memory includes episodic, semantic, declarative, and autobiographical memories. There are four types of neural plasticity: Compensatory masquerade- the use of a new cognitive process to carry out a task that previously depended on a cognitive process that used to be impaired. It is prescribed widely among people diagnosed with borderline personality disorder, depression, anxiety, and post-traumatic stress disorder (PTSD). Some psychologists believe the prefrontal cortex is necessary in order for us to organize and store informatio… I saw "where you lived when you were a child". One sleep cycle: stages are passed through in sequence (Stage 1, 2, 3, then 4), then rise back through the stages (Stage 4, 3, 2, then 1), before entering REM sleep. Korsakoff's syndrome is a chronic memory disorder that is caused by a deficiency of vitamin B1 (thiamine). This means that the hypnosis patient may do and say what the hypnotist expects of them without even meaning to. Episodic memory is a form of long-term memory that captures the details of past events that one has personally experienced. It makes possible mental time travel through subjective time--past, present, and future. Age, weight, date of birth...seems pretty semantic to me but is it still considered semantic because its about one's own experience? Fixation: the failure to see an issue from a new perspective. Semantic memory is more of something you see and can relate with your own life the actual facts and episodic memory I think are like events that happened in your life. Long-term memory is a memory that can last infinitely, for example, remembering the date you were born, the face of your mother, etc. For example, the area of the brain that deals with mathematics (inferior temporal gyrus) would become heightened after taking a calculus class. This type of intelligence can be evaluated by standard tests of intelligence (e.g. Drugs, poisons, and head injuries can hinder our ability to be aware. Sometimes fixation occurs because of a mental set. This is one way false memories can be created. STUDY. For example, when you remember a song and are able to sing along to lyrics. Check out the sidebar for useful resources & intro guides. It then temporarily holds that information in working memory. Adults over the age of 60 have delayed reaction times and slowed speech because their information-processing capabilities have become slower. Short-term memory begins, on average, to decline after the age of sixty. It is now known that new neurons can actually grow in particular areas of the brain, such as the hippocampus and cerebellum. Despite being able to speak a language fluently, we cannot describe the reasons for using particular sentence structures, principles of grammar, etc. The time since something was learned is known as a retention interval. The notion of episodic memory was first proposed some 30 years ago. This technique is known as self-reference. Gravity. masalmeh123. G. Gillund, in Encyclopedia of Human Behavior (Second Edition), 2012. Memories of events that happened before the age of 3 are unreliable, and are susceptible to a phenomenon known as infantile amnesia. We show that fundamental features of episodic memory capacity are present in mammals and birds and that … These synapses are strengthened with use, especially when they are associated with strong emotions. Jerusalem is the capital of Israel). Spatial Intelligence- the ability to see and process the world (space) that surrounds you. Function fixedness is a tendency to observe the functions of things (objects) as static and unchanging. Episodic-like memory software and ROS packages. The majority of Alzheimer's patients are over age 65 (early onset can occur around 40 years old). By using our Services or clicking I agree, you agree to our use of cookies. Stage 1- This stage of sleep has mainly theta waves that are of low to moderate frequency (3-7 Hertz). That being said, I doubt the MCAT will try to trick you in this way. pictures, someone's face, a specific place). Information that is important/meaningful, and information regarding a skill (e.g. PLAY. Irregular Sleep-Wake syndrome is an extreme form of insomnia, with only 1-4 hours of sleep in a period of 24 hours. Associating memories with images has also been shown to aid in recall. One prominent view holds that episodic memory emerged recently in humans and lacks a “(neo)Darwinian evolution” [Tulving E (2002) Annu Rev Psychol 53:1–25]. Belief perseverance is the tendency for us to hold on to our pre-existing beliefs, despite being presented with evidence that contradicts our beliefs. Flashcards. Primary Mental Abilities- Belief is that we are born with seven primary mental abilities: Savant Syndrome is rare, and is characterized by extreme talent in one particular area, such as music, but rather poor cognitive functioning in most other fields. General intelligence (also referred to as the "G factor") is the type of intelligence that underlies all types of intelligence. Before, I always thought episodic = events, while semantic = facts. REM (rapid eye movement)- this is the last stage of sleep, characterized by swift eye movements and the presence of dreams. Originally written by Francis Leconte at 3IT-IntRoLab, Université de Sherbrooke. Three types of recall include: Serial recall is the ability to remember various events, or a list of items in the sequence in which they occurred or, were listed. In addition to memory loss, symptoms of Korsakoff's syndrome include confusion, poor coordination, disrupted speech, and involuntary eye movements. Studies have found that different languages lead to different ways of thinking and reasoning. Episodic memories have a sort of emotional aspect to them which the constantly rehearsed facts lack. Episodic memory is the memory of every day events that can be explicitly stated or conjured. For example, it may be difficult for someone over the age of 60 to follow a weekly routine, such as going to physical therapy twice a week for their 2:00 pm appointment. So for example, if someone asks me what middle school I went to, it could either be semantic or episodic memory. Procedural memory (also known as implicit memory) is the memorization of how to complete a task. An example of a node: the image of a tiger. Chunking is a process that aids in recall by organizing pieces of new information into groups that fit into particular categories. Nature Intelligence- the ability to understand the biological aspects of the world. tranquilizers, Mebaral, Butisol, Nembutal), Prescribed to aid with sleep, anxiety reduction, prevention of seizures, Users feel relaxed and tired, sometimes confused, Can cause slurred speech, slowed heart beat, and weakness, Should never be mixed with alcohol, can be fatal, Benzodiazepines (e.g. Theory of Universal Grammar (UG): all languages are alike in structural foundation, and because of common grammar rules and patterns, we are able to learn to speak without formal instruction. The reticular formation (also referred to as reticular activating system, RAS) structures of our brainstem control levels of arousal. Representative heuristic - we have a tendency to make judgments based on the probability of something happening based on our typical idea of a particular event. The Decay Theory states that if long-term memories are not recalled often, it will become harder and harder (if not impossible) to remember them. Mathematical Intelligence- the ability to perform in numbers (math). Episodic Memory vs Autobiographical Memory. It is the process of the brain finding another way to accomplish something when the first (typical) method is ineffective. Hypnosis is an interaction between a hypnotist and a patient during an induced state of consciousness in which the patient is in a state of being open to the hypnotists' suggestion(s).
