Slide 24: Using the laws you can determine the two objects. The right is recognized as a clock, but how
was that determined?
Slide 25: reverse cookie-cutters- when you place the cutters on top of the dough, you create shapes,
which are the templates. We are talking about the reverse though.
In our heads we have several templates, and several templates are tried until we find the matching
template to the object.
The problem though is that you’d need a diverse number of templates for just one object, since you can
see them from various orientations, and there are various models of it (ex. Chair).
This is just used as a starting point to the speculations.
When you define a chair, you’d use functional descriptions, but you could not relate it to the visual

the object in order to recognize it.
Slide 26: Images of cats and birds pop up, and you have to say whether it’s a cat or bird. You can get
prototypical birds and some that are not (ex. Exotic birds, penguins). The less prototypical images would
