Problem 6: Dual-code theory & propositional theory Flashcards
what is imagery?
a mental representation, usually not connected to the senses. It can be in any sensory form, but the most common is visual
What is dual code theory by Paivio?
We use pictorial and verbal codes for representing things in our minds.
What is analog code in DCT?
mental images, therefore imaginal, that resemble the physical things they represent
What is symbolic code in DCT?
Language, does not literally resemble its physical objects, it is a symbol for something.
What is the propositional theory by Anderson & Bower?
Our mental representations resemble the abstract form of a proposition
What is a proposition?
the meaning underlying a particular relationship among concepts
What happens in image scaling? How has this been proven?
we represent and use mental images in ways that are functionally equivalent to our representations and uses of physical things.
Evidence: It takes people longer to describe details of small images than of larger images.
What is the functional equivalence hypothesis?
Our mental images represent physical things, we use them the same way in our mind as we would in real life
What is the mental imagery debate about?
Do our mental images resemble perception or do they resemble language?
What is prosopagnosia?
People who cannot recognise human faces, though they can recognise other objects fine
What is experimenter expectancy?
The experimenter’s bias affects the outcome of a study by subconsciously influencing the subjects
What is the bizarreness effect?
bizarre images are recalled better than common images
What were the results of a study investigating the role of visual imagery in the bizarreness effect?
Visual imagery had little role in the effect, even if it was controlled for, the effect remained
How could propositions be ‘saved’?
