Study Notes
Cognition and Thinking
- Cognition is the scientific term for thinking and encompasses all mental abilities and processes related to knowledge.
- Cognition includes attention, memory, judgment, reasoning, problem solving, decision making, and other vital processes.
- Human cognition occurs both consciously and unconsciously.
- Cognition is intuitive; it occurs naturally as a part of being human.
- Cognitive processes use existing knowledge and can generate new knowledge through logic and inference.
Key Figures in the Study of Cognition
- Aristotle (384–322 BCE): Laid the foundation for the study of human cognition, emphasizing empirical evidence.
- René Descartes (1596–1650): Famous for the phrase "I think, therefore I am," suggesting that thinking proves our existence.
- Wilhelm Wundt (1832–1920): Considered a founding figure of modern psychology, focusing on the processes of sensation, perception, and cognition.
Sensation, Perception, and Cognition
- Sensation is the initial reception of sensory information by our receptors.
- Perception is the organization and interpretation of sensory information, resulting in a conscious experience.
- Cognitive processes use perceived information for further goals.
Perceptual Illusions
- Ambiguous images demonstrate that our perception can differ from what we sense.
- The "Duck and Rabbit Illusion" highlights mid-level vision, where our brains group visual information based on edges.
- Ambiguous images demonstrate that our perceptions are not always accurate representations of reality.
Top-Down vs. Bottom-Up Processing
- Bottom-Up Processing: Perception starts with sensory input and builds up a larger understanding.
- Top-Down Processing: Perception starts with existing knowledge and expectations, influencing the interpretation of sensory information.
Theories of Perception
- Direct Perception (Ecological Perception): Sensory information and context are sufficient for perception, without the need for cognitive processes.
- Template Theories: We recognize patterns by comparing them to stored mental templates.
Vigilance, Search, and Attention
- Vigilance: Maintaining focused attention over time to detect a specific stimulus.
- Search: Actively scanning the environment for a specific feature.
- Distracters: Non-target stimuli that interfere with finding the target.
Theories of Search Processes
- Display Size Effect: The difficulty of search increases with more items in the visual field.
- Similarity Theory: Search is harder when targets resemble distracters.
- Guided Search Theory: Search involves two stages: parallel activation of potential targets and serial evaluation based on activation level.
The Stroop Effect
- The Stroop effect demonstrates the brain's slowed reaction time when encountering conflicting information.
Selective Attention
- Selective attention allows us to focus on specific stimuli while ignoring distractions.
- This ability to filter information is crucial in managing limited cognitive resources.
