1. in neuroscience, a hypothetical process in which the activation of one neuron is presumed to spread to connected neurons, making it more likely that they will fire.
What is spreading activation in consumer behavior?
“Spreading activation” involves the idea of one memory “triggering” another one. For example, one might think of Coke every time one remembers a favorite (and very wise) professor who frequently brought one to class.
What is meant by spreading activation quizlet?
Define spreading activation. The process through which activity in one node in a network flows outward to other nodes through associative links.
Which is the best example of spreading activation?
For example, in the so-called spreading activation theory of semantic processing, knowledge that is needed to answer questions such as “Can a robin fly?” or “Is a penguin a bird?” is retrieved from such a network by activating the two nodes and having the activations spread between them until they meet.What is MCAT spreading activation?
Spreading activation suggests that, when a concept is activated, the activation spreads to concepts that are semantically or associatively related to it. Thus, people often retrieve unpresented members of a category when tested on their memory for a series of presented concepts from that category.
What is the term for the level at which a node in a spreading activation model will fire?
What is the level at which a node in a spreading activation model will fire? response threshold. Only $35.99/year. Participants are asked to memorize a list of words.
What is shallow and deep processing?
Depth of processing falls on a shallow to deep continuum. Shallow processing (e.g., processing based on phonemic and orthographic components) leads to a fragile memory trace that is susceptible to rapid decay. Conversely, deep processing (e.g., semantic processing) results in a more durable memory trace.
What is activation in linguistics?
Spreading activation is a term used in psychology, psycholinguistics and cognitive linguistics. … The idea is that the linguistic perspective on words changed during this period in such a way as to include more and more aspects beyond the words themselves.What is priming in psych?
In psychology, priming is a technique in which the introduction of one stimulus influences how people respond to a subsequent stimulus. Priming works by activating an association or representation in memory just before another stimulus or task is introduced.
What is an example of proactive interference?Proactive interference occurs when old memories limit one’s capacity to recall new information. You’ve probably already witnessed this phenomenon when trying to recall phone numbers. For instance, the old number you have had for several years can proactively interfere the process of remembering your new phone number.

What is interference effect in psychology?
Interference is a memory phenomenon in which some memories interfere with the retrieval of other memories. Essentially, interference occurs when some information makes it difficult to recall similar material. Similar memories compete, causing some to be more difficult to remember or even forgotten entirely.
What is a semantic network in psychology quizlet?
Semantic network theory (DESCRIBE) a description of the organisation of information in long-term memory in terms of overlapping networks (grids) of interconnected concepts (nodes) ; activating one node during retrieval increases the likelihood that associated nodes become activated. Nodes.
What is the fan effect quizlet?
Fan Effect. The idea that as more data is collected on a concept (and this related) the longer it takes to recall a specific piece of data within that network. Response Competition.
Which experiment involves the use of classical conditioning?
Ivan Pavlov is known for his famous experiment with conditioning the salivation response in dogs, which brought about classical conditioning.
What is priming MCAT?
Priming occurs when a cue related to a semantic memory is presented in an attempt to prompt the memory. Context effects occur when the physical location that an individual is in aids with the retrieval of information.
What are semantic networks and frames?
A semantic network, or frame network is a knowledge base that represents semantic relations between concepts in a network. … It is a directed or undirected graph consisting of vertices, which represent concepts, and edges, which represent semantic relations between concepts, mapping or connecting semantic fields.
What is sensory coding MCAT?
Sensory coding is a type of information processing that occurs in nervous systems and can be thought of as four separate yet related phenomena: Reception, whereby specialized sensory receptors absorb physical energy from sensory stimuli. … Awareness, the possible conscious perception of encoded sensory stimuli.
What is Craik and Lockhart's levels of processing model?
The levels of processing model (Craik & Lockhart, 1972) focuses on the depth of processing involved in memory, and predicts the deeper information is processed, the longer a memory trace will last. … The basic idea is that memory is really just what happens as a result of processing information.
What are the 3 levels of processing?
The visceral level is fast: it makes rapid judgments of what is good or bad, safe or dangerous, and sends appropriate signals to the muscles (the motor system) and alerts the rest of the brain. This is the start of affective processing.
What is automatic and effortful processing?
Automatic processing: The unconscious processing of incidental or well-learned information. Effortful processing: Active processing of information that requires sustained effort. … Deep processing: Processing information with respect to its meaning.
What is a node psychology?
a single point or unit in an associative model of memory.
What is depth of processing MCAT?
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. This effect is known as depth of processing.
What is activation in psychology?
activation, also called arousal, in psychology, the stimulation of the cerebral cortex into a state of general wakefulness, or attention.
What is neural priming?
Neural priming of the brain is like the “ready, set” before the “go” that children shout out before racing each other across a playground. … Priming our visual, auditory and other senses alerts the brain to get ready for more input. Neural priming increases attention, focus, readiness, and accuracy of response.
What is deja vu psychology?
Déjà vu describes that uncanny sensation you’ve already experienced something, even when you know you never have. Experts generally agree this phenomenon probably relates to memory in some way. So, if you have déjà vu, you might have experienced a similar event before. You just can’t remember it.
What is masked repetition priming?
Another set of ERP studies using unmasked picture primes (Hamm et al., 2002; McPherson & Holcomb, 1999) in semantic priming paradigms has reported a frontally distributed negativity, the N300, which has been suggested to reflect object-specific processing (because a similar component has not been reported for words).
Who invented lexical decision task?
Although versions of the task had been used by researchers for a number of years, the term lexical decision task was coined by David E. Meyer and Roger W. Schvaneveldt, who brought the task to prominence in a series of studies on semantic memory and word recognition in the early 1970s.
What is parallel activation?
Parallel language activation during auditory comprehension is a process that has been identified across various language contexts and proficiency levels, and may thus be a relatively ubiquitous source of increased competition during bilinguals’ receptive language processing (Blumenfeld & Marian, 2007; Canseco-Gonzales, …
Why is proactive interference important?
Proactive Interference In other words, old memories interfere with the retrieval of new memories. … As a result, they are easier to recall than memories that were made more recently. Research has shown that one way to reduce proactive interference is to rehearse the new information through testing or recitation.
Why does proactive interference happen?
Proactive interference (pro=forward) occurs when you cannot learn a new task because of an old task that had been learnt. When what we already know interferes with what we are currently learning – where old memories disrupt new memories. … Also new learning can sometimes cause confusion with previous learning.
