Unit 6: Development in Middle Childhood (7-11 years) Flashcards
Between which ages do children grow at a steady rate and what does that mean? (before growth spurt)
7-11
5-8 cm, 2.5-3 kg per year
How does growth increase during the growth spurt?
5-10 cm
4.5-7 kg
Are younger children (2-3 y/o) in control of their attention?
no, their attention gets easily captured by distractors
Why might the ability to sustain attention improve gradually throughout childhood and early adolescence?
maturational changes of CNS
What is the brain structure necessary for sustaining attention and when is it fully myelinated?
reticular formation
puberty
Miller and Weiss conducted studies on the ability of children to resist distraction from task-irrelevant information. The found evidence that this ability improves, but during which ages?
7-13 years
How was the study by Miller and Weiss (ability to resist distractions) structured?
7, 10 and 13 year old’s had to remember locations of toy animals hidden behind a screen
when each screen was lifted to reveal the location of the animal, household objects were above or below each screen
What were the results for children of each age for the Miller & Weiss study (ability to resist distractions)?
7& 10 y/os: less accurate in remembering animals, more accurate in remembering household items (even if that wasn’t the goal of the task)
13 y/o: more accurate in remembering animals, less able to recall household items
-> better at ignoring task-irrelevant information
Miller & Weiss also showed meta-cognition. What is that and how did it show during the study?
knowledge somebody has regarding their own cog. processes
they understand what they have to do (were asked how to do the task), but were unable to do so
Meta-attention
4 y/o children understand that it is harder to pay attention to two people telling stories at a time than hearing one at a time
Meta-memory
4y/o: understand that some things are easier to remember than others
3-5 y/o: remembering many items is more difficult than remembering a few
Which belief of children between the ages of 3-5 suggests, that they view memory storage as a “mental copy” that won’t be lost over time?
belief that remembering sth over short period of time is as easy as over a long period
Towards which age do children form the (more accurate) understanding, that the mind holds interpretations of reality?
11
What’s one strategy to promote memory storage and retrieval?
mnemonics
What are two common types of mnemonics?
rehearsal
organisation
rehearsal
repeating sth until you remember it
Does the ability to implement rehearsal stay static?
no, it improves with age
-> 3-4: try to remember objects by looking carefully and labelling, without rehearsing
-> 7-10: can rehearse, the more they do so, the more they remember
Does rehearsal change with development?
yes
How does rehearsal change with development? (quantity)
5-8 y/o tend to rehearse one word at a time
12 y/o more likely to use active, cumulative rehearsal (multiple words in chunks)
Why are younger children speculated to be unable of using cumulative rehearsal?
limited working memory capacity doesn’t allow holding enough information to form clusters
What is organization and when do children begin using it?
grouping or classifying stimuli into meaningful clusters
-> easier to retain
9-10 years
Which are the 4 stages of development, which ages does each stage include and how do people progress from one stage to the next?
0-2: Sensorimotor intelligence
2-7: Preoperational thought
7-11: concrete operational
11-adulthood: formal operational
-> successful completion of previous stage necessary to advance
What do children accomplish during the pre-operational stage?
think in symbols
What do children accomplish in the concrete-operational stage
use of logic to solve concrete, current problems
What do children accomplish in the formal-operational stage?
solving abstract problems
What is mental seriation and which stage does it occur in?
putting objects in serial order
occurs in concrete operational stage
Which are the two types of errors children in the preoperational stage tend to make when attempting mental seriation?
incomplete ordering (successfully ordering most, but not all)
extension (ordering them so the tops of each stick extends higher than previous one
Transivity
understanding logical relations between series of objects
classification
logical assumptions on objects based on membership to a particular category
reversibility
ability to mentally reverse an action
What’s an example of reversibility? (maths)
understanding that numbers can be changed (addition) and returned to original state (subtraction)
Where are great improvements visible in children, when looking at language? When do these changes occur?
pragmatic system: appropriate and effective use of language in social situations
-> children become more sensitive to needs of others
-> understand humor, irony, etc.
