Sensation And Perception Psychology MCQs

Which of the following is NOT the case in terms of serial and parallel processing models?

by

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

Which TWO of the following statements are true of simultaneous contrast illusions? 1. In the simultaneous tilt illusion, vertical stripes appear tilted away from the tilt of their surrounding stripes. 2. In the luminance illusion, a grey patch appears darker when surrounded by a dark area than when surrounded by a light area. 3 A purple patch appears slightly closer to blue when surrounded by red, and closer to red when seen against a blue background. 4. Visual illusion effect only exist for motion.

by

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

One of the following statements is FALSE-but which one?

by

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

Which of the following is NOT an example of a genuine after-effect?

by

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

Identify the FALSE statement about the neurons in are V1:

by

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

In conjunction search:

by

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

Sometimes the visual information available to us about a stimulus is ambiguous because of differences in depth, lighting or shading cues. For example, patterns of shading can create the illusion of objects as protruding from a visual field. How do we make sense of the visual information to recognize ambiguous stimuli?

by

A. Visual system relies on other people’s Knowledge of objects to identify ambiguous stimuli
B. Visual information about protruding objects is impossible to process
C. Visual system relies on assumptions about the physical world to identify ambiguous stimuli
D. Both (a) and (c)
