Signal detection depends upon
Not quite. The answer is C.
Why: According to Signal Detection Theory, correctly identifying a stimulus is not a simple process. It depends on both the observer's perceptual sensitivity to the signal (d') and their independent, and often unconscious, response criterion (beta) for deciding that a signal is present.
An example of Feature Analysis is:
Not quite. The answer is A.
Why: Feature analysis explains recognition by decomposing a complex pattern into simpler diagnostic elements. Phonics follows this logic in reading: the learner analyses a printed word into letters or letter clusters and maps those visual units onto phonemes before blending them.
According to Gibson’s theory of perception:
Not quite. The answer is A.
Why: J.J. Gibson's ecological or 'direct' theory of perception is a bottom-up model which argues that the visual environment is so rich with information (the 'optic array') that we can perceive it directly.
The inputs from our sensory receptors are structured by
Not quite. The answer is B.
Why: Gestalt principles (closure, proximity, similarity, and continuity) describe how our perceptual system automatically organises raw sensory input into meaningful, structured wholes. These are innate organising tendencies rather than learned or purely analytical rules.
Four important elements in the theory of signal detection are:
Not quite. The answer is C.
Why: Signal Detection Theory (SDT) describes performance in a detection task using four possible outcomes based on the observer's response and the signal's status. These are a 'Hit' (signal present and detected), a 'Miss' (signal present but not detected), a 'False Alarm' (signal absent but detected), and a 'Correct Rejection' (signal absent and not detected).
Which of the following depth cue is based on muscular feedback?
Not quite. The answer is C.
Why: Accommodation is a monocular depth cue that depends on muscular feedback. The brain interprets the amount of strain in the ciliary muscles, which bend the lens to focus, as an indicator of an object's distance.
The influence of surrounding environment on perception is called
Not quite. The answer is D.
Why: This is the definition of a context effect, a key example of top-down processing in perception. The way we interpret a stimulus is strongly influenced by the surrounding environmental information and our expectations, not just the stimulus itself.
________ such as ________ believe that depth perception is innate.
Not quite. The answer is B.
Why: The nativist position in philosophy and psychology, famously associated with René Descartes, proposes that humans are born with certain innate knowledge or abilities. In the context of perception, nativists argue that the ability to perceive depth is an innate, pre-wired capacity, not one learned through experience.
An important factor which enables one to adapt to inverted vision is:
Not quite. The answer is B.
Why: In George Stratton's classic studies on adaptation to inverted vision, it was found that the key to recalibrating perception was not passive viewing but active movement. Interacting with the environment allows the brain to form new correlations between motor commands and the resulting sensory feedback.
Detecting movement in spite of camouflage is easier for people who are:
Not quite. The answer is B.
Why: Field-independent individuals are better at separating an object from its surrounding context or background. This cognitive style allows them to overcome the distracting influence of camouflage and detect the figure (the object) more easily than field-dependent individuals, who tend to see the field as a whole.
