Questions and Answers

Which theory of perception emphasizes the role of top-down processing, where people actively construct their perceptions based on expectations and prior knowledge?

Constructive perception theory (correct)

Bottom-up processing theory

Recognition-by-components theory

Direct perception theory

According to the Ebbinghaus size illusion, how does the perception of the size of one object (the orange circle) get influenced by the size of another object (the black circles)?

The orange circle appears larger when the black circles are smaller. (correct)

The size of the black circles has no effect on the perceived size of the orange circle.

The orange circle appears larger when the black circles are larger.

The orange circle appears smaller when the black circles are larger.

What is the key difference between the direct perception theory and the constructive perception theory in terms of their focus?

Direct perception theory focuses on the neural hierarchy processing increasingly complex stimuli, while constructive perception theory focuses on basing one perception on another.

Direct perception theory focuses on top-down processing, while constructive perception theory focuses on bottom-up processing.

Direct perception theory focuses on the role of context in perception, while constructive perception theory focuses on the role of expectations in perception.

Direct perception theory focuses on identifying and combining elementary features, while constructive perception theory focuses on actively constructing perceptions. (correct)

Study Notes

Theories of Perception

Constructive perception theory emphasizes top-down processing, where individuals actively shape perceptions using expectations and prior knowledge.
Direct perception theory focuses on how sensory information directly leads to perception without the influence of past experiences.

Ebbinghaus Size Illusion

The perception of an object's size, like an orange circle, is influenced by surrounding objects, such as black circles, altering the perceived size through contextual comparison.

Recognition-by-Components (RBC) Theory

Proposed by Biederman, RBC theory suggests that objects are recognized by analyzing their basic three-dimensional components (geons) and their configurations.

Modern Psychological Perspective

The contemporary view emphasizes the significant role of experience and context in shaping perception, recognizing that prior knowledge and expectations play a crucial role.

Depth Perception Cues

Certain perceptual cues, like texture gradient or linear perspective, contribute to the perception of depth; others may not have been specifically mentioned.

Factors Determining Perceived Size

The perceived size of an object is primarily determined by context, relative size, distance, and surrounding elements that influence visual interpretation.

Light-from-Above Heuristic

The light-from-above heuristic is a perceptual assumption that visual scenes are illuminated from above, influencing how shadows are interpreted.

Semantic Regularities in Perception

An example of semantic regularity involves recognizing familiar contexts or scenarios that inform how objects are perceived based on learned associations.

Gestalt Psychology Principles

Gestalt principles, such as proximity or similarity, influence how we group and perceive objects, leading to distinct interpretations of visual data.

Bottom-Up vs. Top-Down Processing

Bottom-up processing involves perception that starts with sensory input, while top-down processing relies on cognitive factors like context and expectations.

Main Message on Processing

The discussion emphasizes the interplay between bottom-up and top-down processing in perception, illustrating how both processes work together to shape human experience.

Heuristics for Visual Input

Key heuristics, like the principle of parsimony and other mental shortcuts, aid in interpreting ambiguous visual information efficiently.

Simple vs. Complex Cells

Simple cells in the striate cortex respond to specific orientations and locations of stimuli while complex cells are more sensitive to motion and can respond to stimuli across a larger area.

Role of Illusions

Illusions highlight the complexities and limitations of visual perception, demonstrating how the brain can misinterpret sensory information.

Perception and External World

The relationship between perception and the external world is characterized by a dynamic interaction where perceptions are not merely reflections of the outside world but are influenced by cognitive processes and experiences.
