Lorenz's & Harlow's Research

The aim of Lorenz's 1935 research was to study:

• the effects of environment on animal behavior

• the process of imprinting in animals

• the genetic basis of behavior

• the social behavior of primates

In Lorenz's experiment, the first large moving object that the goslings saw after hatching was:

• a human

• a dog

• a cat

• a tree

How did Lorenz ensure he was the first large moving object the goslings saw after hatching?

• He stayed close to the eggs until they hatched.

• He used a mirror to reflect his image to the goslings.

• He made loud noises to attract their attention.

• He was the first to feed them after hatching.

What method did Lorenz use to divide the greylag goose eggs in his experiment?

• Random selection

• By size

• By color

• By hatching order

According to Lorenz's research, within what time period does imprinting occur after hatching?

What conclusion did Lorenz draw about imprinting in birds?

• Imprinting is a learned behavior that occurs in the later stages of life.

• Imprinting is an innate behavior that occurs during a critical period shortly after birth.

• Imprinting is a behavior that can be reversed at any time.

• Imprinting is a behavior that only occurs in mammals.

What was the aim of Harlow's 1958 research?

• To study the effects of maternal separation and social isolation on rhesus monkeys

• To investigate the cognitive development stages in children

• To explore the impact of reinforcement on behavior

• To examine the role of genetics in intelligence

How many surrogate mothers did Harlow construct in his experiment?

• One

• Two

• Three

• Four

In Harlow's experiment, what material was used to wrap the second wire mother?

• Cloth

• Plastic

• Metal

• Wood

Based on the results of Harlow's experiment, the baby monkeys preferred the cloth mother over the wire mother because:

• The cloth mother provided food.

• The cloth mother was warmer.

• The cloth mother offered comfort and security.

• The cloth mother was more colorful.
