Mental Imagery

What is mental imagery

Experiencing a sensory impression in the absence of sensory imput

Spatial imagery

The ability to imagine spatial relationships

Object Imagery

Ability to imagine visual details, features and objects

What is the conceptual peg hypothesis

Information associated with vivid mental images is remembered more easily because the images provide meaningful retrieval cues for memory.

Difference between mental images and preceptions

Metal images are less vivid, more fleeting, once disrupted its gone and this can happen anywhere and anytime. For a perception, the object must be present

Spatial Correspondance

People will create images in their minds and scan through the mental image as they are actually moving in space. The mental imagery will match the layout of the actual stimuli.

Tacit knowledge

We unconsciously use knowledge about the world to make judgements. Knowledge gained through experience that is difficult to consciously explain or verbalize, such as knowing how to ride a bike or interpret social cues.

Epiphenomenon

Something that accompanies the real mechanism but is not actually part of the mechanism.

Propositional Representation

Propositional representation is the idea that the brain stores information as meanings and relationships instead of storing exact mental pictures. Example:

According to propositional representation, your brain may store:

• book

• under

• table

instead of storing a full picture of the scene.

Depictive Representations

We create images like a scrapbook, each image is created and pasted to create the mental picture
