Study Notes
Key Types of Color Blindness
- Monochromatism: Total color blindness, only shades of gray are perceived.
- Dichromatism: Partial color blindness, includes Protanopia, Deuteranopia, and Tritanopia (absent cones).
- Anomalous Trichromatism: All three cone types are present but one is altered, resulting in abnormal color responses.
Visual Cliff Experiment
- Conducted by Eleanor Gibson and Richard Walk.
- Investigated if infants possess depth perception.
- Findings: Infants avoided crossing a perceived drop-off, suggesting early depth perception development.
Holway and Boring Experiment
- Demonstrated size perception relies on depth information.
- Found size misperceptions when depth cues were absent.
Key Cues for Depth Perception
- Oculomotor: Involves eye muscle position, including convergence and accommodation.
- Monocular: Using one eye, includes occlusion, relative size, and motion parallax.
- Binocular: Uses both eyes, relying on binocular disparity (stereopsis) for depth perception.
Depth Perception
- Depth perception relies on binocular, monocular, and oculomotor cues.
- The size-distance scaling equation: S = R × D (Size = Retinal size × Distance).
- Key visual illusions include the Müller-Lyer, Ponzo, and Ames Room illusions.
Key Terms/Concepts
- Depth Perception: The ability to perceive the world in three dimensions and accurately judge the distance of objects.
- Oculomotor Cues: Non-visual cues about eye muscle position/tension (convergence and accommodation).
- Monocular Cues: Depth information from a single eye (pictorial and movement-based).
- Binocular Cues: Depth information from both eyes (binocular disparity).
- Size Constancy: The perception that an object maintains a constant size despite changes in retinal size due to distance.
Key People in Language and the Brain
- Paul Broca (1824-1880): A French physician whose research on language focused on Broca's area (speech production).
- Carl Wernicke (1848-1905): A German neurologist who identified Wernicke's area (language comprehension).
Cause and Effect in Language and the Brain
- Damage to Broca's area: Results in Broca's aphasia, affecting speech production and comprehension of complex sentences.
- Damage to Wernicke's area: Results in Wernicke's aphasia, leading to fluent but meaningless speech and an inability to comprehend language.
- Infant-Directed Speech (IDS): Facilitates phoneme distinction and word learning in infants.
- Exposure to Native Language Phonemes: Infants gradually focus on relevant sounds, enhancing language acquisition.
- Phonemes: Smallest units of sound in a language.
- Broca's area location: Frontal lobe.
- Wernicke's area location: Temporal lobe.
- McGurk effect: Demonstrates the interaction between auditory and visual information in speech perception.
Key Anatomy of Taste and Smell
- Papillae: Structures on the tongue containing taste buds (filiform, fungiform, foliate, circumvallate).
- Taste Buds: Contain taste cells with receptor sites, converting taste stimuli to electrical signals.
- Olfactory Mucosa: Area in the nasal cavity with olfactory receptor neurons (ORNs) detecting odorants.
- Olfactory Bulb: Processes signals from ORNs, organizing them into a chemotopic map for odor recognition.
- Piriform Cortex: Primary olfactory area where odor signals are processed.
Fundamental Theories of Taste
- Population Coding: Taste quality is represented by the activity patterns across multiple neurons.
- Specificity Coding: Individual neurons respond specifically to certain taste stimuli (like sweet or bitter).
Cause and Effect in Taste
- Genetic Variations in Taste Receptor Genes: Influences individual differences in taste sensitivity (supertasters vs. non-tasters).
- Environmental Factors (Diet, Culture): Interact with genetics to shape taste preferences over time.
