1. subjects presented with pairs of drawings of 3D cubes structures 2. right image either identical to left but rotated, or mirror image and rotated. 3. had to identify whether: identical, or mirror image 4. hypothesis supported that mental image would be constructed then rotated to determine likeness 5. data showed clear direction of further rotation away from original resulted in longer processing |

Cognition is DES |
Dynamic -unfolds over space and time Embodied - embodied interactions with world provide basis for higher level thought processes, knowledge grounded in physical interaction Situated -we structure physical environment to support our cognitive processes |
|
|
|
Symbol Grounding |
conceptual abstract knowledge must be grounded in our perceptions and interactions with the real world to be retrievable and useable |
