Sensation And Perception

A. How we perceive individual features of objects when brain is impaired
B. How we perceive multiple colours to perceive a whole colour
C. How we integrate touch and vision
D. How we integrate individual features of objects to perceive a whole object

A. The rods and cones in the retina function in bright and dim light respectively
B. The cones are of three types, which are selective to different ranges of light wavelength
C. The information from the cones is re-organized in the retina to give-green, red and blue-yellow opponent channels
D. There is also group of large retinal cells alongside the smaller color-opponent cells that respond to the difference between the luminances in their center and surrounding regions

A. The target/distractor difference is not based on a single feature, but on conjunctions of features
B. Search time for the target is not constant, but instead rises with the number of distractors
C. The observer apparently searches through the display serially, scanning each term or small group of items) successively (serial search)
D. All of the above

A. Recurrent processing model
B. Serial processing model
C. Parallel processing model
D. Selective adaptation model

A. Neurons in V1 adapt to visual stimulation, so their response to a stimulus increases over time with repeated presentation
B. The localized receptive fields and binocular characteristics of V1 neurons correlate very well with the perceptual characteristics of perceptual after-effects
C. The neurons in area V1 are prime candidates for the mechanisms that underlie visual after-effects in people
D. Images of complex objects trees; houses, people are initially analyzed by mechanisms that respond to their local physical characteristics and have no connection with the identity of the objects themselves

A. After running your fingers over fine sandpaper, medium sandpaper feels coarser (and vice versa)
B. After listening to a high tone for a while, a medium auditory tone appears higher
C. Holding your hand under running cold (or hot) water before testing the temperature of baby’s bath water will lead you to misperceive how comfortable the water will be for the baby
D. After eating chocolate, orange juice tastes more tart

A. A system of channels can only signal preferred orientation of any single channel
B. Perceptual information is likely to be merged via a process that combines the activities across all channels
C. As part of the process of synthesis, channel activities are likely to be weighted according to the level of activity in each channel
D. The merging process may find the ‘center of gravity’ of the distribution of activity

A. 1 & 3
B. 2 & 3
C. 3 & 4
D. 2 & 4

A. The serial processing model is now known to be inadequate, or at least incomplete
B. The serial model has been replaced, at or at least modified, firstly by the parallel processing model and then, most recently, by the recurrent processing model
C. According to the parallel processing model, analysis of different stimulus attributes, such as identity and location, proceeds simultaneously along different pathways, even from the earliest stages
D. According to the parallel processing model, the fact that there are cones and rods in the retina is evidence for multiple mechanisms that extract information in series from the retinal image

A. Touch receptors
B. Warmth receptors
C. Pressure receptors
D. Pain receptors
