| # | Front | Back | Hint |
|---|---|---|---|
| 1 | Who is J.J. Gibson and what is his main contribution to sensory perception? | J.J. Gibson was a psychologist known for his ecological approach to perception, emphasizing direct perception through environmental affordances without the need for complex internal processing. | Think 'Gibson' and 'environment' for direct perception |
| 2 | What is Helmholtz's theory of perception, and what role does unconscious inference play? | Helmholtz proposed that perception involves unconscious inference, where the brain interprets sensory input based on prior experience and assumptions to construct a perceptual reality. | Helmholtz = 'hidden assumptions' in perception |
| 3 | How did Gibson's concept of affordances influence our understanding of perception? | Affordances are action possibilities offered by the environment to an observer, emphasizing perception as directly tuned to environmental features relevant for action. | Affordances = 'action opportunities' in surroundings |
| 4 | What distinguishes Helmholtz's approach from Gibson's approach to perception? | Helmholtz's approach emphasizes inferential processes and unconscious assumptions, whereas Gibson's ecological approach emphasizes direct perception without cognitive inference. | Think 'Helmholtz = inference', 'Gibson = directness' |
| 5 | What is the concept of 'unconscious inference' in perception theory? | Unconscious inference refers to the automatic, involuntary process by which the brain interprets sensory information based on prior knowledge, assumptions, and experiences. | Inference happens 'under the surface', unconsciously |
| 6 | Which theorist proposed the idea that perception is direct and does not require mental reconstruction? | J.J. Gibson proposed the ecological approach, suggesting perception is direct and relies on environmental cues without the need for mental reconstruction. | Gibson = 'direct perception' pioneer |
| 7 | What is the main critique of Helmholtz's theory regarding perceptual inference? | Critics argue that Helmholtz's emphasis on unconscious inference underestimates the role of direct perception and environmental cues in perception. | Helmholtz = 'inferential', critics seek 'directness' |
| 8 | How does Gibson's concept of 'optic flow' relate to perception? | Optic flow refers to the pattern of visual motion perceived as an observer moves through the environment, aiding in navigation and understanding of spatial layout. | Flow = 'visual motion cues' |
| 9 | Name a practical application of Gibson’s ecological approach in technology. | Designing user interfaces that utilize natural environmental cues and affordances to improve usability and accessibility. | Think 'environmental cues' in interface design |
| 10 | What did Helmholtz mean by 'perceptual constancy' and why is it important? | Perceptual constancy is the tendency to perceive stable properties of objects (like size, shape, color) despite changes in sensory input, crucial for reliable perception. | Constancy = perception of stability |
| 11 | How does Gibson's theory explain the perception of motion? | Gibson believed motion perception arises from the direct detection of optic flow patterns, without needing complex interpretative processes. | Motion = 'flow patterns' perceived directly |
| 12 | What is the significance of 'environmental affordances' in perception theories? | Environmental affordances specify what actions are possible with objects or surroundings, emphasizing perception's role in guiding behavior. | Affordances guide 'action possibilities' |
| 13 | Which major perception theory emphasizes the role of environmental stimuli over internal mental processes? | Gibson's ecological approach emphasizes direct perception driven by environmental stimuli, minimizing the role of internal inference. | Think 'ecological = environment-driven' |
| 14 | In Helmholtz's theory, what role does prior experience play in perception? | Prior experience informs unconscious inferences, helping the brain interpret ambiguous sensory information based on learned assumptions. | Experience = 'mental shortcuts' in perception |
| 15 | Describe a key difference between Gibson's and Helmholtz's views on perception. | Gibson advocates for direct perception via environmental cues, while Helmholtz emphasizes inferential processing based on prior knowledge. | Direct vs. inferential perception |
| 16 | What is meant by 'perceptual adaptation' in the context of sensory perception theories? | Perceptual adaptation refers to the process by which perception adjusts to changes in sensory input or environment, often explained through inferential or direct mechanisms. | Adaptation = 'perceptual flexibility' |
| 17 | How did Gibson’s theory influence modern virtual reality (VR) design? | Gibson’s focus on environmental cues and affordances informs VR design to create immersive, intuitive experiences that users perceive as natural. | VR interfaces utilize 'environmental cues' |
| 18 | What is the main criticism of Gibson’s ecological approach? | Some critics argue that Gibson's approach underestimates the complexity of internal cognitive processes involved in perception. | Critics question 'directness' assumption |
| 19 | Which perception theorist’s ideas have influenced the development of computer vision systems? | Gibson’s ecological approach has influenced computer vision, emphasizing the extraction of environmental cues from visual data for object and scene recognition. | Computer vision = inspired by 'direct perception' |
| 20 | What role does 'bottom-up processing' play in Gibson’s and Helmholtz’s theories? | In Gibson’s theory, bottom-up processing involves direct extraction of environmental information; Helmholtz also considers sensory data as starting points for inference. | Bottom-up = data-driven, from environment or senses |
