Lorenz-animal studies Flashcards
A01
Outline Ethology
Ethologists conduct animal studies of the relationship between newborn animals & their mothers , their observations informed psychologists understanding of caregiver infant attachment in humans
Ethologist-Lorenz
A01
Define Imprinting
When an animal strongly attaches to first moving object encountered.The animal will follow object.
A01
Discuss Research:Lorenz(1935) Imprinting
Lorenz is an Ethologist- Observed phenomenon of imprinting as child, neighbour gave newly hatched duck that followed him
A01
Outline the Procedure of Lorenz’s research
> lorenz set up experiment
Randomly divided half greylag goose egges
half eggs hatched by Lorenz using incubator
half hatched by mother( control group)
A01
Outline Lorenz’s Findings
Goslings hatched by lorenz-imprinted on him & followed him
Goslings hatched naturally by mother-imprinted on mother & followed her
When 2 groups placed together half imprinted on lorenz continued to follow him
This phenomenon-called imprinting
control group-mother, experimental group-Lorenz
A01
What does Lorenz’s research suggest?
Imprinting is a strong biological feature of attachment
when birds imprint-based on visual cues
A01
What is the Critical period for attachment: Lorenz
Findings
32 hours
> If Goslings not find moving object to imprint on within 32 hours-will fail to form attachment(irreversible)
suggests-imprinting is strong evolutionary/ biological feature of attachments in birds & imprinting happened on large moving objects
A01
Explain sexual Imprinting-refer to Lorenz
Lorenz investigated relationship between imprinting & adult mate preferences.
Observed that birds who imprinted on humans will display courtship behaviour
In case study-lorenz described peacock who was born surrounded by turtles, only desired to mate with turtles in later life.
Concluded-peacock undergrone sexual Imprinting
A03
Generalisability to humans (limitations) A03
Limitation
ability to generalise to humans
>The mammalian attachment system is diff and complex to birds
>mammalian attachment- two way process Youngs don’t only become attached to mothers, mothers also show emotional attachments back
> cannot generalise/inappropriate
A03
Research support for Imprinting
Strength
Regolin & vallortigara (1995) study supported Lorenz’s ideas of imprinting.
Chicks were exposed to shape combinations that moved
-chicks followed shapes
supports view-animals born with inate mechanism to imprint on first moving object
