Exploring Sensation and Perception in Psychology

What is the primary difference between sensation and perception?

• Sensation involves interpretation, while perception is about raw data.

• Both involve high-level cognitive processing.

• Both are directly influenced by external stimuli only.

• Perception involves interpretation, while sensation is about raw data.

What does top-down processing require?

• No prior knowledge or experiences

• Just the raw sensory data

• Only visual sensory data

• Prior knowledge and experiences

According to Gestalt psychology, how are objects perceived?

• Individually without relation to other objects

• Based on past experiences only

• In their simplest forms

• In their most complex forms

What principle explains the perception of a continuous line or pattern?

• Continuation

• Symmetry

• Closure

• Proximity

Which cue is an example of a binocular cue for depth perception?

• Texture gradient

• Retinal disparity

• Linear perspective

• Relative size

What does the monocular cue of relative height indicate?

• Objects lower down are perceived as less detailed.

• Objects higher up are perceived as more detailed.

• Objects lower down are perceived as closer.

• Objects higher up are perceived as closer.

What is sensory transduction?

• The process of reducing response to stimuli.

• The adaptation to unchanging stimuli.

• The conversion of a stimulus to a sensory signal.

• The detection of changes in stimulus intensity.

What does the absolute threshold refer to?

• The average level of stimulus detection over time.

• The minimum level of a stimulus that can be detected.

• The change in stimulus detection due to adaptation.

• The maximum level of a stimulus that can be detected.

What does Weber-Fechner's law relate to?

• The cognitive interpretation of different stimuli.

• The change in stimulus intensity needed to detect a difference.

• The psychological factors affecting stimulus detection.

• The relationship between stimulus and physical response.

What is an example of sensory adaptation?

• Noticing a smell immediately after it is introduced.

• Becoming less aware of a continuous smell over time.

• Detecting changes in sound intensity immediately.

• Increasing sensitivity to light changes in a room.
