Describe the main cognitive characteristics of a child in the concrete operational stage
What will be an ideal response?
In the concrete operational stage, children show the beginnings of adult logic but focus on tangible objects rather than abstract ideals. Concrete-operational thought is reversible and flexible. Concrete-operational children are less egocentric than preoperational children. They recognize that people see things in different ways. Concrete-operational children also engage in decentration and can focus on multiple parts of a problem or situation. Concrete-operational children show understanding of the laws of conservation. Concrete-operational children can understand the concept of transitivity and can engage in seriation. They can also put things into classes and realize that objects can be in subclasses, too. For example, they can understand that a dog is also an animal.

Calculate and report the observers' interobserver reliability.
Two observers observe a child in the classroom every 30 minutes to record whether he is behaving aggressively. They use two categories for their observations: yes (aggressive) or no (not aggressive). Using the data presented below, answer the following question.

In one research study, Hilgard asked hypnotized subjects to submerge one hand in a tub of ice-cold water. Participants were told they would feel no pain, but they were also told that they could use the nonsubmerged hand to signal any pain by pressing a telegraph key. The participants kept one hand submerged in the water, as instructed, but with the other hand they pressed the key frequently
Later they claimed to have no memory of pressing the key. Hilgard's results support the view that hypnosis involves: a. creative role engagement b. a trancelike state with increased delta wave activity c. subliminal perception of environmental cues d. divided conscious awareness
