During which Piagetian stage does a child first demonstrate the ability to use logical reasoning about concrete objects and events?

Question 2

A behavior analyst observes that a 6-month-old infant reaches persistently for a toy hidden under a blanket. This behavior best illustrates:

Accepted Answer

Question 3

In Bronfenbrenner's ecological model, the microsystem refers to:

Accepted Answer

Direct settings where the child actively participates

Answer

The microsystem includes immediate environments—home, school, peers—where the child has direct, face-to-face interactions.

Question 4

Which learning mechanism explains why a toddler begins labeling objects after watching a parent label them, without direct reinforcement?

Accepted Answer

Observational learning

Answer

Observational (vicarious) learning, described by Bandura, allows acquisition of behavior through watching a model without direct reinforcement.

Question 5

A behavior analyst notes that a child's tantrums are maintained by escape from demands. Developmentally, understanding that escape-maintained behavior often emerges because:

Accepted Answer
