Correct answer: first sensory-motor psychological tests- A. Spearman
- B. Raven
- C. Cattell
- D. Rorschach

Correct answer: Cattell- A. Robert Sternberg
- B. David Wechsler
- C. Louis Thurstone
- D. Charles Spearman
Explanation: Charles Spearman proposed that performance on different mental tasks reflects a common general intelligence factor, called g.
Correct answer: Charles Spearman- A. blue, yellow, red
- B. blue, green, red
- C. green, orange, red
- D. green, yellow, red
Explanation: In the traditional psychology classification, red, yellow, and blue are treated as the primary colours for subtractive mixing, while red…
Correct answer: blue, yellow, red- A. retinal disparity
- B. interposition
- C. continuity
- D. convergence
Explanation: Convergence is the inward turning of the eyes when viewing a nearby object, and the brain uses the degree of muscular effort as a cue to…
Correct answer: convergence2129. The tendency to organize stimuli into smooth, uninterrupted patterns is called _________________?
- A. closure
- B. continuity
- C. similarity
- D. proximity
Explanation: The Gestalt principle of continuity leads us to perceive lines and patterns as smooth, ongoing forms rather than as disconnected pieces.
Correct answer: continuity- A. motivation
- B. past experience
- C. size
- D. expectation
Explanation: Motivation, past experience, and expectation are personal factors because they arise from the observer.
Correct answer: size- A. cones
- B. rods
- C. lens
- D. cornea
Explanation: Rods are highly sensitive to dim light and support night or peripheral vision, although they do not provide detailed colour vision.
Correct answer: rods- A. size constancy
- B. brightness constancy
- C. linear perspective
- D. texture gradient
Explanation: Brightness constancy allows a familiar object to be perceived as having a stable brightness despite changes in illumination, so the white…
Correct answer: brightness constancy- A. a stimulus factor in perception
- B. a personal factor in perception
- C. a stimulus factor in motivation
- D. a Gestalt principle of perception
Explanation: Bold type is a physical feature of the text that attracts attention, making it a stimulus factor in perception.
Correct answer: a stimulus factor in perception- A. fovea
- B. iris
- C. cornea
- D. retina
Explanation: The fovea is the central retinal area with the greatest concentration of cones, providing the sharpest and most detailed vision.
Correct answer: fovea- A. clairvoyants
- B. telepaths
- C. parapsychologists
- D. levitators
Explanation: Parapsychologists investigate alleged extrasensory phenomena such as telepathy and clairvoyance.
Correct answer: parapsychologists- A. frequencies
- B. Hertz
- C. wavelengths
- D. decibels
Explanation: Sound amplitude is commonly expressed as sound level in decibels, whereas frequency is measured in hertz.
Correct answer: decibels- A. perceptual consistency
- B. relative motion
- C. linear perspective
- D. continuity
Explanation: Perceptual constancy allows an object to be perceived as stable even when its retinal image changes as the observer moves.
Correct answer: perceptual consistency- A. perceptual set
- B. retinal disparity
- C. convergence
- D. visual capture
Explanation: A perceptual set is a mental readiness to perceive something in a particular way, shaped by expectations, experience, or context.
Correct answer: perceptual set- A. convergence
- B. linear perspective
- C. relative motion
- D. retinal disparity
Explanation: Retinal disparity is the slight difference between the images received by the two eyes, which the brain uses to judge depth.
Correct answer: retinal disparity- A. sensory adaptation
- B. feature detection
- C. signal detection
- D. transduction
Explanation: Transduction changes physical stimulation, such as light or sound, into neural signals that the nervous system can process.
Correct answer: transduction
