Q

pendulum problem

A

46
Q

the formal operations stage in Piagets theory can be explained as ______

A

a stage where people can learn to think systematically and deal with abstract ideas

48
Q

what are the two keys to cognition in the information processing approach

Q

What aspect of adolescent egocentrism makes adolescents much more self-conscious than they were in middle childhood?

A

imaginary audience - they think everyone is looking at and thinking about them

Q

proximal development

A

The zone of proximal development is the difference between skills or tasks a person can accomplish alone and those they are capable of doing if guided by a more experienced person.

59
Q

scaffolding

A

Scaffolding refers to the degree of assistance provided in the zone of proximal development.

60
Q

does scaffolding and proximal development continue into adolescence

A

Scaffolding and the zone of proximal development continue to apply during adolescence, when the skills necessary for adult work are being learned.

61
Q

In Vygotsky’s view, how does learning take place

A

Learning is a social process between someone who has the knowledge and someone who is obtaining it

62
Q

how is learning always a cultural process

A

People are acquiring knowledge for things that will be useful in their culture.

63
Q

You were recently watching your nephew try to figure out why his bike gears won’t work. You are surprised by his systematic problem-solving strategies. A few months ago, he would not have been able to think hypothetically like this. According to Piaget, what type of reasoning is he using?

ways to obtain information into LM

69
Q

Experience Sampling Method (ESM)

A

people wear wristwatch beepers or using mobile phones to alert them randomly during the day so that they can record their thoughts, feelings and behaviour

A

higher levels of responsibility and intense social comparison

74
Q

Why does social comparison get more intense during adolescence than it was in childhood?

Because teens develop adolescent egocentrism which involves the ‘personal fable’ and ‘imaginary audience where people think that everyone always judges them on how the look and what they achieve or don’t achieve.

88
Q

A

using this approach have been shown to be effective in reducing arrests and out-of-home placements among delinquents (Henggeler et al., 20072363). Furthermore, multisystemic programs have been found to be cheaper than other programs, primarily because they reduce the amount of time that delinquent adolescents spend in foster homes and detention centres
