Chapter 12 - Development over the Lifespan Flashcards
1
Q
what does developmental psychology do
A
examine changes in our biological, physical, and behavioural processes as we age
2
Q
cross-sectional design
A
comparing people of different ages at the same point in time.
3
Q
pros of cross-sectional design
A
Data from many age groups can be collected quickly
4
Q
cons of cross-sectional design
A
different age groups grew up in different historical periods. Thus the results may be due to environmental differences, rather than ageing
5
Q
what is a cohort
A
an age group
6
Q
longitudinal design
A
repeatedly test the same cohort as it grows older
7
Q
cons of longitudinal design
A
Time consuming
Sample may shrink as people drop out of study, move, die.
results may be due to developmental experiences unique to the cohort, not due to ageing
8
Q
sequential design
A
combines cross-sectional and longitudinal
repeatedly test several age cohorts as they grow older
9
Q
cons of sequential design
A
most time-consuming and costly
10
Q
pros of sequential design
A
most comprehensive
11
Q
what are the three types of research designs that psychologists use to investigate age related changes?
A
cross-sectional design
Longitudinal design
Sequential design

120
what age is the basic trust versus basic mistrust
first year
121
what is the basic trust versus basic mistrust stage
depending on how much love and attention we get during the first year of life, we develop a basic trust or mistrust of the world
122
what age is the autonomy vs shame and doubt stage
1 to 2 years old

PreconventionalConventionalPostconventional
179
Preconventional moral reasoning
based on anticipated punishments or rewards
180
very conventional moral reasoning stage one
focussed on punishment"Steal the drug, if wife dies, he'll get into trouble"

Preconventional moral reasoning stage two
focussed on rewards"Steal drug, because then wife will still be with him"
182
conventional moral reasoning
based on conformity to social expectations, laws, and duties
183
conventional moral reasoning stage three
conformity stems from the desire to gain peoples approval"People will think he's bad if he doesn't steal the drug to save his wife"
184
conventional moral reasoning stage four
Believe that the laws must be obeyed because the rules need to be followed"Steel drug, it's his duty to take care of his wife"
185
Postconventional moral reasoning
based on well thought out, general moral principles
186
Postconventional moral reasoning stage five
recognizing importance of societal laws, but taking individual rights into account"Stealing is illegal, but reasonable because he saved a life"
187
Postconventional moral reasoning stage six
