Questions and Answers

According to template theory, what do template theorists argue exists in our mind?

Infinite storage of sensory experiences

Abstract concepts unrelated to perception

Unlimited capacity for new recognition

Templates or object representations of things we have perceived before (correct)

What is a drawback of the template theory from a Biological Plausibility standpoint?

The brain lacks the capacity to store templates

Storing trillions of templates is not efficient for object recognition (correct)

Templates cannot be updated with new information

Templates are not flexible enough for varied experiences

What real-life application is provided as an example related to the template theory?

Digital image processing

Barcodes representing the same thing (correct)

Augmented reality experiences

Virtual reality simulations

Study Notes

Theories of Object Recognition and Brain Processing

Captcha is a bot prevention program using distorted letters to prevent template recognition by bots
Top-Down processing theory suggests that we recognize objects as a whole and switched to words to aid perception
Feature Analysis Theory argues that we recognize objects by identifying a combination of features
The RBC model by Biederman suggests that we recognize objects by 3D components called geons
The model explains that adding color and texture makes it easier to distinguish objects
Limitations of the RBC model include difficulty in recognizing objects with unique features
The ongoing debate is whether we recognize objects as parts or as a whole
Repetition Suppression (RS) phenomenon suggests that brain activation lessens with repeated exposure to an object
Perspective of objects matters in perceiving them, as shown by RS experiments
Left hemisphere of the brain is view invariant, while the right hemisphere is view dependent
Dorsal and Ventral Streams are two parallel processing pathways for perceiving information
The Ventral Stream helps identify objects and link them to memory, while the Dorsal Stream helps understand object location and usage
