2 kinds of knowledge structures:
• declarative knowledge • procedural knowledge
What is a symbolic representation?
relationship btw. representation and the to-be-represented is arbitrary (e.g. cat and an actual cat)
Imagery …
… is the mental representation of things that are not currently seen or sensed by the sense organs.
According to “dual-code theory” we use …
… both pictorial and verbal codes for representing information.
Analog codes …
… resemble the objects they represent.
Propositional theory:
we do not store mental representations in the form of images or mere words. They more closly resemble the abstract form of a proposition.

An example for a proposition:
eat
What can be expressed in form of a proposition:
• actions • attributes • spatial position • category membership
What can be used to show that mental images are not truly analogous to perceptions of physical objects?
ambiguous figures (Chambers & Reisberg)
Semantic labels …
… clearly influence mental images.
Critiques showed that part.s could reinterpret ambiguous figures, with the help of 1 of 4 hints:
• implicit reference-frame hint • explicit reference-frame hint • attentional hint • construals from “good” parts
According to the functional-equivalence hypothesis, although …
… visual imagery is not identical to visual perception, it is functionally equivalent.
5 general principles of visual imagery by Finke, give 2 examples:
• our mental movements across images correspond to those of physical percepts. • Mental images can be used to generate info that was not explicitly stored during encoding.
What can be used to provide evidence for the functional-equivalence hypothesis?
• mental rotation and response times • image scaling • image scanning
Corresponding to spatial neglect there also is …
… representational neglect.
Some suggest that representations may take any of the following forms:
propositions, images or mental models.
Mental models are structures …
… that individuals construct to understand and explain tehir experiences.
Two kind of images:
• visual • spatial
Cognitive maps are …
… internal representations of our physical environment.
3 types of knowledge used when forming mental maps:
• landmark knowledge (imaginal and propositional representations) • route-road knowledge (procedural and declarative knowledge) • survey knowledge (imaginal and propositional)
The 3 types of knowledge used in forming mental maps suggest that people …
… use both: analogical and propositional code e.g. for images of maps.
