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)
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
moro reflex
rooting reflex
babinski reflex
grasp reflex
perceptual development
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
stages of language development (crying, cooing, babbling, word comprehension, echolalia, first words, holophrasic & telegraphic speech)
nativist view of language development (Chomsky)
natu*rist view of language development (learning theory)
Sapir-Whorf hypothesis
*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)
