Q

Why do psychologists look at animal studies?

A

. Their behaviour can be similar to humans

Q

Give a short summary about Konrad Lorenz

A

. Old white male from 1960s
. Spent a lot of his life with geese
. Influential ethologist
. Looked at animal behaviour, specially imprinting, when he was a child
. Neighbour gave him a duckling who followed him around

Q

What is imprinting?

A

An innate readiness to develop a strong bond with the first moving object which takes place during a specific time in development, probably the first few hours after birth/hatching (critical period)

Q

How was imprinting seen in Lorenz’s study?

A

When young goslings are born, they follow the first large, moving object they see innately and attach to them

Q

What was the procedure of Lorenz (1935)?

A

Took a clutch of gosling eggs and divided them into two groups

Group 1: left with natural mother (control group)
Group 2: left in incubator (experimental group)

When the incubator eggs hatched, the first thing the Gosling’s saw was Lorenz
When the natural eggs hatched, the first thing they saw was their natural mother

Q

What are the findings of Lorenz (1935)?

A

. Once the goslings hatched, they followed the first moving object they saw during the critical period (12-17 hours)
. Lorenz’s geese (incubated ones) showed no recognition of their natural mother
. Lorenz found that imprinting to humans doesn’t work for some animals e.g curlews won’t imprint on a human

Q

What is the critical period in Lorenz’s study and what is significant about it?

A

12-17 hours: imprinting will not occur if the animal isn’t exposed to a moving object in this critical period

Q

What conclusions can be drawn from Lorenz’s study?

A

. Attachment is innate and genetic: supports view that having a biological basis for attachment is adaptive
. Highlighted the idea of a critical period
. Imprinting is an innate process

Q

How did Lorenz test the effects of imprinting immediately after his study?

A

Marked the two different groups and put them together, with both Lorenz and the natural mother present. The incubator group continued to imprint on Lorenz only

Q

What were the long-lasting effects of Lorenz’s study?

A

. Early imprinting had an effect later on for mate preferences = sexual imprinting
. Several features of imprinting were noted by Lorenz in 1952

Q

What are the features of imprinting (Lorenz 1952)?

A

. Occurs without any feeding taking place
. Irreversible
. If no attachment has developed within 32 hours, it’s unlikely any attachment will develop
. Imprinting has consequences for methods of short-term survival
. Imprinting helps to develop internal templates for later relationships

Q

What is sexual imprinting?

A

When a young animal learns and bases the characteristics of a mate off of observations from an early age. Animal will choose to mate with the same kind of object they were imprinted on.

Q

What was the aim of Harlow’s monkeys (1959)?

A

To show that attachment isn’t based on the feeding bond between mother and infant as suggested by learning theories of attachment

17
Q

What was the procedure of Harlow’s monkeys?

A

8 rhesus monkeys studied for 165 days

There were two surrogate (fake) wire mothers:
1. Cloth mother
2. Wire mother

4 monkeys had a feeding tube on the ‘cloth mother’
4 monkeys had a feeding tube on the ‘wire mother’

18
Q

What was measured in Harlow’s monkeys?

A

. Time monkey spent with each ‘mother’
. Observations of responses when frightened by a mechanical teddy bear

19
Q

What were the findings of Harlow’s monkeys experiment?

A

. All monkeys spent most time with the cloth mother, no matter who had the feeding tube
. Those feeding on the wire mother only went to it in desperate need for food before jumping back to the cloth mother
. When frightened, all monkeys clung to the cloth mother
. When playing with new objects, kept a foot on the cloth mother for safety (proximity for secure base)

20
Q

What main conclusion can be drawn from Harlow’s monkeys experiment?

A

Attachment isn’t based on the feeding bond but best contact comfort

21
Q

How did Harlow investigate the long-lasting effects of his experiment?

A

Continued to study the monkeys as they grew up

22
Q

What were the long-lasting effects on the rhesus monkeys?

A

. Motherless monkeys, even with contact comforts developed abnormally:
- socially abnormal: froze/fled around other monkeys
- sexually abnormal: no normal mating behaviour and didn’t cradle own babies

. Harlow found a critical period for these effects:
. If motherless monkeys spent time with monkey ‘peers’ before 3 months, they could recover and develop normal attachments
- after 6 months with the wire mother, monkeys couldn’t recover

23
Q

What did a Lorenz case study in 1952 to support sexual imprinting say?

A

A peacock was brought up in a reptile house of a zoo, the first moving thing it saw after hatching was a giant tortoise
- as an adult, the peacock would only display courtship behaviour (mating behaviour) towards giant tortoises
