Cognitive Adolescent Development Flashcards
(34 cards)
basic level cognitive functions
attention
perception and memory
high level cognitive functions
logical reasoning
problem solving
Cognitive function in adolescents - we are interested in three interrelated concepts:
- Content of adolescent cognitive functions
- Structure in which adolescents’ cognitive functions are organized
- Process by which adolescents perform basic and higher functions
What is perception
Perception is a cognitive ability that is present from early on in life.
What happens to perception with development
change in the flexibility of perceptiopn
how is flexibility of visual perception tested
ambiguous figures
what is selective attention
selective attention is the ability to allocate attentional resources and focus on a specifc object
Crucial for problem solving where you may need to pay attention to relevant information and ignore irrelevant information
what is processing speed
the time it takes the brain to receive or output information; or the speed in which mental calculation can be carried out
what is the development of processing speed driven by
maturation of white matter in the brain
what can be used to investigate white matter in the brain
diffusion tensor imaging
what is STM
required for a short duration of time
subject to temporal decay and chunk capacity limits
STM is often measured using
span task
spatial span task
span task
series of items presented at the rate of 1/sec; task is to repeat them in the same order
spatial span task
blocks are presented in a particular arrangement and the experiment taps the blocks in a specific order; aprticipants are required to repeat the sequence.
what happens to chunk capacity during adolescence
improves
what about immediate recall
age related improvements in immediate recall remain costant across varying retention intervals from 5-30 seconds of delay
explanations for age-related improvement in STM
-Neurological changes
-volummetric changes in the medial temporal lobe due to sexual maturation
-gray matter changes in the frontal love as a result of brain maturation
3 different conceptualisations of WM:
- Short term memory applied to cognitive tasks
- A multi component system that holds and manipulates information in short term memory
- The use of attention to manage short term memory
WM often measured using
modified span task
letter span task
modified span task
participants are presented with a series of items and asked to reproduce them in reverse order
letter span task
a list of random letters are presented, and participants are required to repeat the letters in the order they appear.
memory formation
relies on brain plasticity.
Our brains retain an ability to learn due to experience-dependent plasticity
During sensitive periods, the plasticity of our brains is experience-expectant
