Chapter 9: Physical and Cognitive Development in Middle Childhood Flashcards
At what age is middle childhood?
6-12 years old
Growth patterns in middle childhood
5 cm to 8cm in height and about ____ kg are added each year.
2.75
_____ in middle childhood are ahead of ____ in their overall rate of growth.
girls, boys
Sex differences in skeletal and muscular maturation cause girls (on average) to be better coordinated but _______ slower and somewhat physically weaker than boys.
physically
By age ___, girls have attained about 93% of their adult height, while boys have reached only 84% of theirs.
12
In middle childhood, there’s a steady ______ in the myelinization of neural axons across the cerebral cortex.
increase
Right hemisphere lateralization contributes to increased ______ perception
spatial
_______ ________ is the ability to infer rules and make predictions about the movement of objects in space- where things are in relation to each other.
This improves in middle childhood
Boys score better than girls do in this tests.
Spatial cognition
______ ______ ______ (BMI) measures the proportion of body fat to lean body mass.
Body Mass Index
One quarter of Canadian children between ages __ and __ now have unhealthy/suboptimal body weights.
5 and 11
Obesity results from __________ and ________ factors
environmental and genetic
This is Piaget’s proposed stage in middle childhood
Kids at this age become more logical about concrete and specific things but they still struggle with abstract ideas.
Concrete Operational stage
_________ ________ - a set of mental schemes such as reversibility, addition, subtraction, multiplication, division, and serial ordering, that enable children to understand relationships among objects.
Concrete operations
_________ logic involves going from a specific experience to a general principle.
Inductive
This is a term wherein children in this concrete operations period realize that physical properties stay the same even when outward appearances change.
Conservation
_________ is thinking that takes multiple variables into account. ( A clay ball rolled into a sausage shape is wider but is also shorter than before)
Decentration
In ________ _________ (reversibility), you are seeing the understanding that both physical actions and mental operations can be reversed. They can now retrace their thinking.
reversible thinking
__________ _________ is a term where children can now flexibly group objects into hierarchies and they are consistent in how they group the objects into those hierarchies.
Hierarchical classification
In __________, the child now has an overall plan when they’re arranging the sticks. You would see the, organize smallest to largest.
seriation
________ _________(Inductive logic) allows the child to go from a specific experience to a general principle
ex: If A=B, B=C, then A=C
Transitive Inference
_________ _________ is a term when children are able to do distance and speed problems and also create cognitive maps much better than before.
ex: they aren’t making errors in the problem about the trains.
Spatial Operations
In this phenomenon, Piaget said that it takes children years to apply their new cognitive abilities to all kinds of problems.
- shift from preoperational to operational thinking doe snot happen overnight.
- children shift back and forth between preoperational and concrete operational.
Horizontal Decalage
Robert Siegler, a neo-Piagetian, suggests there are no stages, only _________
problem solving rules emerge from experience and trial and error rather than being specifically linked to age.
sequences
_________ is increasing with age.
Memory
