Dual-coding theory does not take into account the possibility of cognition being mediated by something other than words and images. Not enough research has been done to determine if words and images are the only way we remember items, and the theory would not hold true if another form of codes were discovered. [5]
A wide range of research methods are used in psychology. These methods vary by the sources from which information is obtained, how that information is sampled, and the types of instruments that are used in data collection. Methods also vary by whether they collect qualitative data, quantitative data or both.
For example, visual priming works best with visual cues and verbal priming works best with verbal cues. But priming also occurs between modalities, [7] or between semantically related words such as "doctor" and "nurse". [8] [9] In 2012, a great amount of priming research was thrown into doubt as part of the replication crisis.
For example, for the letter R in the word "card", an observer might be asked to choose between the letter R and T, and will usually be more efficient in doing so than if they are asked to make the same choice with the string of letters such as "cqrd". [1] Each possible completion with the two possible letters in the word condition produce a word.
According to the Atkinson-Shiffrin memory model or multi-store model, for information to be firmly implanted in memory it must pass through three stages of mental processing: sensory memory, short-term memory, and long-term memory. [7] An example of this is the working memory model.
Whether the focus be on social psychology or cognitive psychology, there are many examples of dual process theories produced throughout the past. The following just show a glimpse into the variety that can be found. [citation needed] Peter Wason and Jonathan St B. T. Evans suggested dual process theory in 1974. [4]
Visual Depiction of Left and Right Hemispheres during Semantic Processing. Above is an example of what differences in the Left and Right Hemispheres may look like during semantic processing. If one was told asked for the associations of the word "corn," the Left Hemisphere would most likely quickly prime the image circled above, a corn on the cob.
TRACE is a connectionist model of speech perception, proposed by James McClelland and Jeffrey Elman in 1986. [1] It is based on a structure called "the TRACE", a dynamic processing structure made up of a network of units, which performs as the system's working memory as well as the perceptual processing mechanism.
