Developmental Flashcards
qualitative developmental change
- differences between adults and children are qualitative, not quantitative
- periods of little change alternate with periods of abrupt and rapid change
quantitative developmental change
- differences between adults and children are quantitative, not qualitative
- development is continuous - new abilities, skills, and knowledge develop gradually over time
microsystem
- everyday environment that a person is in
- school, work, home, neighborhood, etc.
mesosystem
- interactions between microsystem
- school & home, work & friends, etc.
exosystem
- relationship between two or more settings, with at least one of the entities only indirectly affecting the person
- example parents + parent’s workplace policies, legal/social services available
macrosystem
- systems that are involved in the environment
- culture, religion, economy, politics
chronosystem
- refers to the passage of time in an individuals life and the changes that take place over time
- birth of a sibling, moving to a new neighborhood
genotype vs. phenotype
genotype = genetic make up of a person, contains both expressed and unexpressed characteristics
phenotype = observable characteristics of the person
normative vs. non-normative influences on development
normative = events that occur in a similar way for most people
non-normative = events that are unusual and have a major impact on an individual’s life
sex chromosomes (ovum, sperm, zygote, female, male)
- ovum = X
- sperm = X or Y
- sperm + ovum = zygote
- XX = female
- XY = male
Down’s syndrome vs. phenylketonuria (PKU)
Down’s
- 3 chromosomes on chromosome 21
- intellectual disability, broad skull, slanted eyes, physical deformities, reduced activity
PKU
- inherited autosomal recessive disorder
- severe mental deficiency
- special diet required
- if detected early, side effects can be prevented
sexual dimorphism
- systematic differences between individuals of different sex
- example = different levels/types of hormones at different stages of life
moro reflex
- baby extending legs/arms/fingers and arching back in response to being startled
rooting reflex
- baby turning the head, opening the mouth, and sucking when their cheek is stroked
babinski reflex
- baby spreading toes and twisting the foot when sole of the foot is stroked
grasp reflex
- baby makes a firm fist around an object that is placed in the hand
perceptual development
- touch = first
- hearing and smell = well developed at birth
- vision = least developed at birth
- tase - preference for sweet
- pain = present at birth. Exposure to painful procedures for full term babies increases pain responsivity. But REDUCES pain responsivity for preterm babies.
primary vs. secondary aging
primary = inevitable changes in physical and mental processes, aging in genetically controlled
secondary = disease, disuse, neglect of the body
social buffer hypothesis
- a person’s perception of having an adequate social network (a good support network can reduce the risk of emotional distress)
stages of language development (crying, cooing, babbling, word comprehension, echolalia, first words, holophrasic & telegraphic speech)
- crying
- cooing 6-8weeks
- babbling 3-6months
- word comprehension 8-9months
- echolalia 9months
- first words 10-15months
- holophrasic speech (single word to express entire thought) 12-15 months
- telegraphic speech (putting 2 words together to express an entire thought) 18-24months
nativist view of language development (Chomsky)
- Noam Chomsky
- believed children are born with an innate language acquisition device (LAD) that prewires us for language
- only minimal exposure to adult language is necessary
natu*rist view of language development (learning theory)
- language is acquired by interacting with the environment and through a process of imitation and reinforcement
*focus on u in word to know it’s learning vs natIvist (Chomsky)
Sapir-Whorf hypothesis
- speakers of different languages think differently because of the structure of their languages
*support for this hypothesis is mixed
components of verbal language
Phonemes → smallest units of sound (d, sh)
Morphemes → smallest units of language that have meaning (words, suffixes, prefixes like do, dog, ing, er (latter ones can be combined to make word). Free morpheme (test, certain) and bound morpheme (pre in pretest and un in uncertain)
Semantics → meaning of words, phrases, sentences. LITERAL meaning*
Syntax → how words are organized into phrases and words
Pragmatics → how language is used in a social context to communicate effectively (example = taking turns in conversations, tone of voice). Understanding of non literal language (sarcasm/humour)
