• A. loudness and intensity
• B. resonance
• C. brightness and hue
• D. frequency

Explanation: A sound becomes softer as it travels farther because its intensity decreases, so loudness helps the listener estimate distance traveled.

• A. frequency theory
• B. opponent-process theory
• C. isomorphism
• D. trichromatic theory

Explanation: Opponent-process theory challenged the trichromatic account associated with Helmholtz by proposing paired color processes such as…

• A. false sensation
• B. wrong perception
• C. false belief
• D. both a and b

Explanation: An illusion is an incorrect interpretation of a real sensory stimulus, so it is best described as wrong perception.

• A. complete figures that have a gap in them
• B. prefer differential contours
• C. associate the distal and proximal stimuli
• D. view on the basis of texture gradient

Explanation: The Gestalt principle of closure leads us to mentally fill gaps and perceive an incomplete figure as a complete one.

• A. temporal lobe
• B. occipital lobe
• C. parietal lobe
• D. frontal lobe

Explanation: Auditory information is processed primarily in the auditory cortex of the temporal lobe.

• A. Purkinje effect
• B. Zeigarnik effect
• C. Young-Helmholtz effect
• D. light adaptation

Explanation: The Purkinje effect refers to the shift toward greater sensitivity to shorter wavelengths in dim light, making blue-green hues appear…

• A. relative size
• B. linear perspective
• C. convergence
• D. interposition

Explanation: Convergence is a binocular depth cue because the brain uses the inward turning of both eyes to estimate distance.

• A. loudness
• B. frequency
• C. distance
• D. timber

Explanation: Frequency is a physical property of sound and corresponds mainly to perceived pitch.

• A. closure
• B. similarity
• C. proximity
• D. relative size

Explanation: Closure, similarity, and proximity are Gestalt principles of perceptual organization, whereas relative size is a monocular depth cue.

• A. innate capability index
• B. innate surface structure ability
• C. prosody index
• D. language acquisition device

Explanation: Chomsky proposed a language acquisition device, an innate human capacity that helps children detect and learn the structural rules of…

• A. organize movements in terms of purpose
• B. do something when instructed verbally
• C. make movements
• D. both a and b

Explanation: Apraxia is the inability to organise and carry out a learned, purposeful movement, even when the person understands the instruction and…

• A. psycho-grammarists
• B. psycholinguists
• C. psycho-metricians
• D. morphemologists

Explanation: Psycholinguistics examines how language is represented, understood, produced, and acquired.

• A. the morphemes used
• B. the phonemes used
• C. both morphemes and phonemes
• D. the rules used to connect phrases

Explanation: Grammar is the system of rules that determines how words and phrases are organized into meaningful sentences.

• A. the surface structure of a sentence
• B. the smallest unit of meaning in a language
• C. the deep structure of a sentence
• D. the basic declarative thought of the sentence

Explanation: A kernel is a simple basic sentence underlying more complex forms and serving as the source for transformational operations.

• A. Phonological
• B. Morphological
• C. Prosody
• D. Syntax

Explanation: Syntax consists of rules governing how words are arranged to form phrases and sentences, so it determines word order.

• A. reading
• B. speaking fluently
• C. remembering past events
• D. understanding other people when they speak

Explanation: Broca’s area supports speech production, so damage commonly causes slow, effortful or nonfluent speech even when comprehension is…

• A. Wernicke's area
• B. cerebellum
• C. thalamus
• D. hippocampus

Explanation: Wernicke's area is important for understanding spoken and written language, making it a key speech-related brain area.

• A. Broca's area
• B. the sensory cortex
• C. association areas
• D. the limbic system

Explanation: Association areas integrate sensory information with stored knowledge and memories, helping the brain recognize and interpret current…

• A. understanding language
• B. producing language
• C. encoding new information into long-term memory
• D. processing sensory information

Explanation: The hippocampus is essential for forming and consolidating new long-term declarative memories, so damage causes anterograde memory…

• A. Broca's area
• B. Sylvain fissure
• C. Wernicke's area
• D. fissure of Ronaldo

Explanation: Broca’s area, usually in the left frontal lobe, is central to planning and producing fluent speech.
