Psychology 6084 MCQs [All-Courses]

thumb

Psychology is the scientific study of human behavior, mental processes, emotions, and personality. It is an important subject for competitive exams such as PPSC, FPSC, NTS, OTS, KPPSC, BPSC, AJKPSC, CSS, and PMS.

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?
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)
Correct Answer: Visual system relies on assumptions about the physical world to identify ambiguous stimuli
How are cortical cells arranged to best transmit neural information?
A Cells are vertically organized in columns
B Cells are horizontally organized in straight lines
C Cells are organized around the optic nerve
D Cells are vertically organized by volume
Correct Answer: Cells are vertically organized in columns
Feature integration theory attempts to explain which aspect of object 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
Correct Answer: How we integrate individual features of objects to perceive a whole object
Which of the following statements is NOT true?
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
Correct Answer: The rods and cones in the retina function in bright and dim light respectively
In conjunction search:
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
Correct Answer: All of the above
When visual information out an object is perceived, which model of perceptual processing emphasizes on-going feedback between the higher centers of the brain(e.g., cognition) and the early stages of processing (e.g., sensory receptors)?
A Recurrent processing model
B Serial processing model
C Parallel processing model
D Selective adaptation model
Correct Answer: Recurrent processing model
Identify the FALSE statement about the neurons in are V1:
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
Correct Answer: Neurons in V1 adapt to visual stimulation, so their response to a stimulus increases over time with repeated presentation
Which of the following is NOT an example of a genuine after-effect?
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
Correct Answer: After listening to a high tone for a while, a medium auditory tone appears higher
One of the following statements is FALSE-but which one?
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
Correct Answer: A system of channels can only signal preferred orientation of any single channel
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.
A 1 & 3
B 2 & 3
C 3 & 4
D 2 & 4
Correct Answer: 1 & 3
