Infancy Flashcards
Sum total of all the genes a person inherits
Genotype
The features that are actually expressed in a person
Phenotype
Child’s phenotype influences their
Environment
Child’s environment influences their
Genotypes
How environmental influences actually affect the expression of their genes
Epigenetics
Maternal effects on prenatal environment
Mothers genes, mothers age, disease, nutrition, mothers emotional state, stress, depression
Which period is most critically affected by teratogens
Embryonic
form of non-associative learning in which an innate response to a stimulus decreases after repeated or prolonged presentations of that stimulus
Habituation
the fast recovery of a response that has undergone habituation, typically as a result of the presentation of a novel, strong or sometimes noxious stimulus.
Dishabituation
How our brains make use of information that has already been brought into the brain by one or more of the sensory systems
Top-down processing
When the environment (stimuli) influence our thinking
Bottom-up processing
When our thinking influences how we see, understand, or perceive the environment
Top-down processing
Piaget’s object permanence starts to develop around what age and what stage
8 months, sensorimotor stage
Infant habituation patterns are predictive of
Cognitive skills
Types of learning: picking up information from the environment and detecting statistically predictable patterns
Statistical learning
Types of learning: if I smile, you smile
Statistical learning
Types of learning: ability to use prior experiences to predict what will occur in the future
Rational learning
Types of learning: learning by acting on the world rather than passively observing it
Active learning
Involves forming an association between two stimuli, resulting in a learned response
Classical conditioning
Unconditioned stimulus (food), unconditioned response
Neutral stimulus (bell), no response
During conditioning: associating the neutral stimulus(bell) with the unconditioned stimulus(food), the unconditioned response is salivating. After conditioning, the bell alone will produce salivating.
Classical conditioning
This type of conditioning involves reinforcement and punishment
Operant conditioning
In operant conditioning, this increases the behavior
Reinforcement
In operant conditioning, this decreases the behavior
Punishment
When something pleasant or rewarding is given after a specific behavior
Positive reinforcement
