What is the Logogen theory?
n. a theoretical memory unit corresponding to a word, letter, or digit, which, when excited, results in the output (recognition) of the unit and recall of characteristics and information associated with that unit.
What is Morton’s Logogen model?
The logogen model of speech processing was developed by Morton (1969). The model is based on the assumption that listeners have a vast number of specialized recognition units, that each are able to recognize one specific word.
What is the interactive activation model?
According to this interactive-activation model, the WSE is explained as such: When the target letter is presented within a word, the feature detectors, letter detectors and word detectors will all be activated, adding weight to the final recognition of the stimulus.
What is trace model?
The Trace model is an interactive model of auditory word recognition, meaning that the model allows an effect of sentence context at any moment during word recognition. In the connectionist TRACE model, word elements are represented by nodes in a network.
What is the cohort theory?
The concept of generational cohort theory proposes that a generation of individuals that share the same political, economic and social events during the early stages of life will develop a similar set of beliefs, values and behavior (Inglehart, 1997; Dinas and Stoker, 2014; Pew Research Center, 2015; Padayachee, 2017).
What do geons do?
Geons represent the basic units of objects and consist of simple shapes, such as cylinders and pyramids. Recognition-by-components theory states that object recognition occurs by representing each object as a combination of basic units (geons) that make up that object.
What is interactive compensatory model of reading?
The interactive-compensatory model of reading was developed primarily to explain developmental and individual differences in the use of context to facilitate word recognition during reading. The work leading up to the model is summarized, and more recent empirical studies are described.
What was the original motivation for mcclelland and Rumelhart’s interactive-activation and competition IAC model?
Our initial interest in parallel distributed processing mechanisms grew out of an attempt to capture our ideas about continuous, interactive processes, particularly as they applied to the problems of visual word recognition and reading.
What is Ganong effect?
The “Ganong effect” is the tendency to perceive an ambiguous speech sound as a phoneme that would complete a real word, rather than completing a nonsense/fake word.
What is an example of cohort?
Examples of cohorts commonly used in sociological research include birth cohorts (a group of people born during the same period of time, like a generation) and educational cohorts (a group of people who begin schooling or an educational program at the same time, like this year’s freshman class of college students).
What are the characteristics of a cohort study?
The characteristic feature of a cohort study is that the investigator identifies subjects at a point in time when they do not have the outcome of interest and compares the incidence of the outcome of interest among groups of exposed and unexposed (or less exposed) subjects.
What is the origin of the word logogen?
The word logogen can be traced back to the Greek-language word logos, which means “word”, and genus, which means “birth”. British scientist John Morton ‘s logogen model was designed to explain word recognition using a new type of unit known as a logogen.
What is an example of a logogen in psychology?
For example, the image of a table is activated by hearing or observing the word table or associated terms. LOGOGEN: “In one of the many memory models, a logogen is a standalone memory unit which corresponds to letters and digits.”
What is the logogen model used for in linguistics?
The logogen model can be used to help linguists explain particular occurrences in the human language. The most-helpful application of the model is to show how one accesses words and their meanings in the lexicon.
What are some of the criticisms of the logogen theory?
Also, another criticism is that the logogen theory was supposed to predict that stimulus degradation should affect priming and word frequency in humans. However, many psychologists have conducted studies and researched the model to show that only priming and not word frequency is interacted with stimulus degradation.
