unit1 aos2- developmental Flashcards
lifespan development
the age related changes that occur from conception until time of death
developmental norms
standards by which the progress of a child’s development can be measured
areas of development
physical
cognitive
social
emotional
continuous development
gradual ongoing change throughout life
discontinuous development
specific stages with bursts of rapid development
nature vs nurture
whether our development is due mainly to genetics (hereditary) or the environment
maturation
preprogrammed developmental process.
orderly sequence of development of the NS and bodily structures
principle of readiness
unless the necessary physical maturation has occurred, no amount of practice will produce a particular mental process or behaviour
sensitive period
the period of time in which an organism is more responsive to certain stimulation
critical periods
narrow period of time where development in an animal is preprogrammed for learning to occur
epigenetics
the study of how environmental factors affect how genes are expressed
monozygotic twins
identical
zygote splits into two- 100% genetically identical twins
Dizygotic
non-identical
two eggs are released at the same time
share 50% of genes
criticism of twin studies
parents tend to treat identical twins more similarly than non identical twins
adoption studies
research using ppl who have been adopted, as well as their adoptive and biological parents, as participants
attachment
the emotional bond that forms between two people
characteristics of an attachment psss
proximity maintenance
safe haven
secure base
separation distress
secure attachment`
uses care-g as a base for exploration
shows signs of seperation anxiety, but easily soothed by care-g
60%
insecure avoidant attachment
20%
infant doesnt seek closeness with caregiver
when seperated, infant shows no signs of separation anxiety
infant ignores care-g upon return
causes of insecure avoidant attachment
neglect and/or abuse
insecure resistant attachment
infant appears anxious even in presence of care-g
extreme distress when care-g leaves
seeks care-g when reunited but difficult to soothe
12%
causes of insecure resistant attachment
care-g who are frequently unresponsive to infant’s needs
disorganised attachment
behaviour is inconsistent with patterns displayed in secure and insecure attachment and seemingly contradictory
eg responding to reunions with fearful behaviour
seeking contact with care-g upon reunion but moving very slowly
possible causes of disorganised attachment
hostile caregiving, care-g experiencing trauma or loss, post natal depression
