Chapter 16: cognitive development in adolescents Flashcards
Why is adolescence so important?
Many mental disorders arise in this period of life. Prevention should start at an early age
What is adolescent thinking? Name 3 aspects
- Process by which adolescents perform intellectual functions
- The structure in which adolescents’ thoughts are organized
- Content of the thinking
What 2 things are developing in adolescents concerning perception? And how does it develop (name 3 things)?
- Seeing ambiguous figures in multiple ways
- See composite objects as a whole or seperate objects and switching attention to both parts
How: increased flexibility, increased knowledge and selective attention
What is selective attention? With what type of task is this measured?
Focus attention in a goal directed manner
Central-incidental learning task = Adolescents selectively maintain attention to the central objects as required by the command of the task
How is selective attention represented in the brain?
Different activity in V1 between percepts
How do people with ASD perceive ambiguous figures?
They less often see two percepts, but if they are instructed to see them both, they can see it
What is the Flanker task and which people find this task very hard? What can help these people?
Attending to the direction of a central arrow to measure selective attention
Mild to borderline intellectual disability –> easier with structured and quiet environment
What is meant with the speed of processing and how does it develop in adolescence?
The time it takes for the brain to receive or output information and the time it takes for a mental calculation to be carried out
Improvement over adolescence because of maturation white matter/myelination
What 4 types of memory were discussed in the lecture?
- Face recognition
- Short-term memory
- Working memory
- Long-term memory
What is the encoding switch hypothesis? What type of face processing occurs in children and which type in older children/adolescents?
Claim that young children rely more on information of faces that isn’t as good for remembering them compared to older children
- Young children: featural processing (separate face features)
- Older children: configuration processing (relations face features)
What is short term memory and what is a span task? How does short-term memory develop in adolescents?
Short-term storage of information
Span task = Series of items is presented at a rate of 1 per second and the participant has to repeat the items
- Increase in short-term memory capacity
- Increase in general knowledge about what has to be remembered
What is working memory and with what type of task is it measured?
Processing and structuring of information
Complex span task: e.g. set of numbers is named and you have to answer by saying the numbers in reverse
How does working memory develop in adolescents in the brain?
Increase in activity in the dorsolateral PFC
What disability impairs working memory?
ADHD
What is a good working memory a good predictor of? Name 2 things
- Study success
- Self control (substance use)
Is working memory training effective?
It’s only effective to the category you practice in, but it’s not generalizable to other capacities
What is long-term memory and with what type of task is it measured?
The long-term storage of information
Speed of card sorting task: sorting cards on physical similarity (AB or ab or aa etc.) or on name similarity (Aa or Bb or bb etc.)
Reaction time decreases with age
