Study Notes
Sensation
- Involves processing basic information from the external world
- Uses receptors in sense organs and the brain
Perception
- Organizes and interprets sensory information
- Focuses on objects, events, and spatial layout
Methods for Studying Infant Visual Perception
- Preferential-looking Technique:
- Method for studying visual attention in infants
- Presents two images simultaneously
- Measures preference by observing which image infants look at longer
- Fantz Visual Stimuli:
- Used in preferential-looking technique
- Developed by Robert Fantz
- Involves presenting visual stimuli to study infant perception
- Modern Version with Automatic Eye Tracker:
- Contemporary adaptation of preferential-looking technique
- Incorporates automatic eye-tracking technology for more precise measurements of infant visual attention
Visual Acuity and Colour Perception
- Visual Acuity:
- Definition: Sharpness and clarity of vision
- Assessed through the ability to perceive simple and complex patterns
- Contrast Sensitivity
- Definition: Ability to detect differences in light and dark areas
- Involves distinguishing between high-contrasting and low-contrasting patterns
- Cone Cells:
- Light-sensitive neurons concentrated in the fovea (central retina)
- Critical for visual acuity
- Development in infants is not fully developed at birth, leading to lower acuity (e.g., 20/120 at birth)
- Colour Perception Development:
- Emerges around 2 months of age
- Infants show a preference for unique hues over combinations of hues
- Research using fNIRS suggests colour language categories exist in an infant's brain before birth
- Infants demonstrate a preference for colour categorization before acquiring language skills
Face Perception in Infancy
- Infants prefer face-like shapes
- Face perception is shaped by perceptual narrowing
- As infants gain experience with faces (particularly their own race/social group) their ability to distinguish faces outside familiar categories decreases
- This leads to a narrowing of their face perception abilities, becoming more adept at recognizing familiar faces and less skilled at identifying unfamiliar ones
Newborn Stage to 9 Months
- Newborn stage: general bias for face-like stimuli, with interest in human and monkey faces
- 6-month-olds: discriminate between human and monkey faces, generalist approach
- 9-month-olds: specialization occurs, focusing solely on human faces
- Attentional changes across development
- 4 months: eyes are the focus of fixation
- 6 months +: fixation on mouths
- 2 years: infants can track where others are looking
Object Perception
- Perceptual Constancy: Perceiving objects as maintaining constant size, shape, and color despite variations in the retinal image.
- Object segregation
- Identification of separate objects in a visual array
- Infants benefit from experience with specific objects in understanding physical properties
Role of Culture in Object Perception
- Culture plays a significant role in how infants perceive scenes, influencing where they focus their attention
- Early experiences affect the way infants perceive different cultural backgrounds and their relationships to each other
Depth Perception
- Optical expansion: As objects get closer, they project a larger image on the retina
- Binocular disparity: Differences between what each eye sees
- Stereopsis: Emerges between 4 and 7 months, and allows perception of distance and depth
- Monocular depth: Pictorial cues
Auditory Perception
- Hearing is the most advanced sense at birth, but there are still improvements across infancy
- Auditory localization: Perception of the location of a sound source
Taste and Smell
- Infants' sensitivity to taste develops prenatally.
- Infants can recognize the smell of their mothers and possibly other women
Motor Milestones
- Infants progress quickly in acquiring basic movement patterns
- Differences exist across individuals and cultures
Visual Cliff
- Experimental apparatus used to study depth perception
- Infants' responses to the drop-off demonstrate their ability to integrate visual cues
Habituation
- Simple, adaptive learning form; decrease in response to repeated stimulation
- Learning has taken place.
- Bilingual infants show faster habituation
Classical Conditioning
- Associating an initial stimulus with a stimulus that always evokes a particular reflexive response
Operant Conditioning
- Learning the relationship between one's behavior and its consequences
Observational Learning/Imitation
- Learning through observation of other people's behavior
Language Development
- The Components of Language
- Generative system for an infinite number of sentences
- Phonemes (smallest units of meaningful sound)
- Morphemes (smallest units of meaning)
- Syntax (rules for combining words into sentences)
Language in Human and Nonhuman Primates
- Chimpanzees and bonobos have demonstrated communicative abilities
- Washoe and Koko learned ASL and combined signs
- Kanzi used a lexigram system to communicate
- Understanding of various aspects of language, such as semantics, syntax, and pragmatics
Hemispheric Language Differences
- Left hemisphere involved in comprehension and production, especially for right-handed individuals
- Some ability for the right hemisphere to compensate for damage to the left hemisphere.
- Early years are sensitive to language learning
Sensitive Period of Acquisition
- Learning language is highly receptive during early years/childhood
Research on Language Learning in Humans
- Genie's case study highlights the critical role of early exposure to language
- Adults' language learning abilities
- Deaf community language learners
Speech Perception
- Understanding prosody
- Categorical perception
- Voice onset time (VOT)
- Word segmentation
