mental imagery (imagery, visualizing)
the mental representation of stimuli when those stimuli are not physically present (can be defined as pictures in the mind or a visual representation in the absence of environmental input.)
the mental representation of visual stimuli (information which passes through the brain as though something is being perceived, when nothing is actually happening.)
the mental representation of auditory stimuli.
Imagery relies exclusively on
top down processing
uses previous knowledge to gather and interpret the stimuli registered by the senses
you to register information through the receptors in your sensory organs (such as your eyes and ears)
uses both bottom up and top down processing.
a representation that closely resembles the physical object ( the word analog suggests the word analogy, such as the analogy between the real object and the mental image)
mental imagery is a close relative of perception
an abstract, language-like representation, storage is neither visual nor spatial, and it does not physically resemble the original stimulus
propositional code approach
mental imagery is a close relative of language, not perception.
cannot recognize human faces visually, though they perceive other objects relatively normally, also have comparable problems in creating visual imagery for faces
the researchers biases and expectations influence the outcomes of the experiment (participants might—either consciously or unconsciously—adjust their search speeds according to the researchers' expectations)
characteristics of visual images
1. When people rotate a visual image, a large rotation takes them longer, just as they take longer when making a large rotation with a physical stimulus.
2. People make distance judgments in a similar fashion for visual images and for physical stimuli.
3. People make decisions about shape in a similar fashion for visual images and for physical stimuli. This conclusion holds true for both simple shapes (angles formed by hands on a clock) and complex shapes (geographic regions, like Colorado or West Virginia).
are all the cues that might convey the experimenters hypothesis to the participant.
you create a mental image of an object that closely resembles the actual perceptual image on your retina
