Monkeys had higher confidence in their ability to remember an image when the visual contrast was high. These kinds of metacognitive illusions -- false beliefs about how we learn or remember best -- are shared by humans, leading brain and cognitive scientists to believe that metacognition could have an evolutionary basis.

feature detectors

Feature detectors: specialised neurons that respond only to certain sensory information. David Hubel and Torsten Wiesel demonstrated that specialised neurons in the visual cortext have the ability to respond to specific features of an image - such as curves, angles, lines, and movements.  

ex: an area just behind your right ear enables you to perceive faces. damage to this area may result in prosopagnosia - a disorder that causes an inability to detect differences in faces. people suffering from this cannot even recognise their own face in the mirror.
