Sensation: the ability to detect a stimulus and, perhaps, to turn that detection into a private experience Perception: the act of giving meaning to a detected sensation Condillac: mental [...]
A little light physics Light: electromagnetic radiation o Wave: an oscillation that travels through a medium by transferring energy from one particle or point to another without causing any [...]
Visual acuity: oh say, can you see? Acuity: the smallest spatial detail that can be resolved o Vision scientists: the smallest visual angle of a cycle of grating that [...]
What and where pathways V2 cells take the surround into account, and can therefor see the difference between a grey square in a black surround and a black square [...]
Basic principles of colour perception The more light a surface absorbs the darker it appears, the colour we perceive depends on the wavelengths of the light that is [...]
Realism: there is a real world to sense Positivism: all we really have to go on is the evidence of senses, so the world might be nothing more than [...]
The retinal array contains far more info than we can process Attention: a family of mechanisms that restrict processing in various ways o External versus internal attention External: attention [...]
Motion aftereffect (MAE): the illusion of motion of a stationary object (in the opposite direction) that occurs after prolonged exposure to a moving object o Waterfall illusion Computation of [...]
Basic qualities of sound waves: frequency and amplitude Amplitude/intensity: the magnitude of displacement (the difference between the highest pressure area and the lowest pressure area) of a sound pressure [...]
Sound localization Two potential types of info for determining the source of a sound: Even though sound travels fast, the pressure wave will not arrive at both ears at [...]
Vestibular organs: the set of five organs –three semi-circular canals and two otolith organs- located in each inner ear that sense head motion and head orientation with respect to [...]
Olfactory physiology Odours and odorants Odour: olfactory sensations Odorant: the chemical compounds that form the stimuli for odours o To be smelled, odorant molecules must be able to float [...]
Taste versus flavour Retronasal olfactory sensation: the sensation of an odour that is perceived when chewing and swallowing force an odorant in the mouth up behind the palate into [...]
