What is Collins and Loftus network model of long term memory?
Collins and Loftus proposed the semantic network model for human memory in 1975 based on earlier models. The basic ideas from the model are still in use today. This model proposes a netlike organization of concepts in memory, with many interconnections. Each concept can be represented as a node.
What is a semantic network in psychology?
A semantic network is a representation of memory that describes the organization of declarative facts and knowledge in the mind. A network consists of a set of nodes and a set of edges. Each node in the network denotes a concept in semantic memory, such as fish or purple.
What is the spreading activation model?
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 a major criticism of the Collins and quillian network model?
The Collins and Quillian model cannot explain the typicality effect, in which reaction times for statements about an object are faster for more typical members of a category than for less typical members.
What are 2 theories of forgetting from STM?
Forgetting information from short term memory (STM) can be explained using the theories of trace decay and displacement. Forgetting from long term memory (LTM) can be explained using the theories of interference, retrieval failure and lack of consolidation.
What is the difference between semantic and episodic memory?
Semantic memory is focused on general knowledge about the world and includes facts, concepts, and ideas. Episodic memory, on the other hand, involves the recollection of particular life experiences.
What is semantic memory tulving?
Semantic memory consists of a “mental thesaurus” that provides “the memory necessary for the use of language” (Tulving, 1972 , p. 386), whereas episodic memory consists of memory for “temporally dated episodes or events, and the temporal-spatial relations” among them (Tulving, 1972 , p. 385).
What is priming in memory?
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 part of the brain is responsible for semantic memory?
anterior temporal lobe
The part of the brain responsible for the way we understand words, meanings and concepts has been revealed as the anterior temporal lobe – a region just in front of the ears.
What is activation by cognitive psychology?
Activation may be interpreted metaphorically as a kind of mental energy that drives cognitive processing. Cognitive structures, such as concepts, are called chunks. Activation spreads from a set of chunks that are the current focus of attention through associations among chunks in memory.
What is semantic priming?
Semantic priming refers to the observation that a response to a target (e.g., dog) is faster when it is preceded by a semantically related prime (e.g., cat) compared to an unrelated prime (e.g., car).
Are sentence verification techniques sensitive to reading difficulty of text?
Two studies are reported which assess whether a sentence verification technique for measuring reading comprehension is sensitive to reading difficulty of text. Fifth and sixth grade students and fourth and sixth grade students-read text passages two grade levels below reading level, at reading level, and two grades above
Does the SAT Reading Comprehension score correlate with sentence verification scores?
The correlations between the SAT reading comprehension score and the proportion correct and the d’ score from the sentence verification test were .49 and .50, respectively. DISCUSSION
Is type of test sentence a significant source of variance?
rect scores which included type of test sentence as a variable. This analysis indicated that type of item was a significant source of variance, F(3, 120) = 401.0, p < .01, with the pattern of means being very similar to those reported in Experiment 1. Correlations. The subjects in the study had recently taken the Stanford Achieve-
