Human Development

According to Piaget, during the formal operational stage people begin to:

• use abstract thinking

• adhere to social norms

• distinguish between good and bad behaviors

• become aware of the positive and negative consequences of their own behaviors

Piaget study only children. He came up with 4 stages of development. The correct order of the stages was

• sensorimotor, preoperational, concrete operational and then formal operational.

• preoperational, concrete operational, formal operational and then sensorimotor.

• sensorimotor, concrete operational, formal operational and then preoperational.

• Preoperational, concrete operational, sensorimotor and then formal operational.

The 5 year old brain weighs nearly 90% of the adult brain because

• children grow new neurons

• neurotransmitters develop with age

• glial cells and neuron connections increase

• pruning of unnecessary synapses occur

The decline in grey matter is the result of .................. pruning

Early adverse experiences can interfere with

• neuron development

• development of neuron connections

• pruning mechanisms

• the ability to crawl

It takes a year (approx) for an infant to learn to walk. This is because

• grey matter is un-developed

• the pre-frontal cortex is un-developed in infants

• infants need to grow more neurons before walking

• myelination develops in the legs last

The adolescent brain is at peak grey matter volume of it's lifetime because

• synaptic pruning is at its peak

• the brain begins to die after adolescence

• adults are not learning as much as adolescents

• the amygdala is at it's peak volume

Piaget's 1st stage of cognitive development is considered

• Formal operational

• Concrete operational

• Pre-operational

• Sensorimotor

As a child develops complex emotions often become a combination of several other emotions. Envy could be a combination of

• sadness and anger

• happiness and surprise

• surprise and disgust

• joy and anger

Which of the following stages in human development is characterized by the ability to think abstractly and use deductive reasoning?

• Sensorimotor

• Preoperational

• Concrete operational

• Formal operational
