What form should a 'guiding representation' in Treisman's feature integration theory take? | It might be better to think of a ‘guiding representation’ as a control device. Its contents are abstracted from the main pathway and it, in turn, controls access to the attentional bottleneck. However, it would not, itself, be part of the pathway. |
Why does Treisman's feature integration theory need a modification to the 'guiding representation' theory? | 1. multiple examples of ‘features’that are available early but that are not available to guide the deployment of attention. 2. there are properties of guiding attributes that are not reflected in attentive vision. |
What is an example for the 'guiding representation' in Treisman's feature integration theory? | The hypothetical control module guides selection like a security screener at an airport. Based on a rather abstract representation of the notion of ‘threat’, the screener selects some individuals for more attention than others. |
What are the undoubted guiding attributes? | Colour, motion, orientation and size . |
