Pepperberg Flashcards
Which of the learning approach assumptions does Pepperberg apply to?
- Social learning helps to explain changes in behaviour - model/rival approach, attention, retention, production, motivation
- Conditioning helps to explain changes in behaviour - operant conditioning using reward
Explain social learning theory
our environment is a key part of learning, and through this we can learn things.
- Attention
- Retention
- Motivation
- Production
Explain operant conditioning
Operant conditioning is learning through outcome. It uses reinforcement and punishment - whether that is positive or negative.
Explain the model/rival technique used in Pepperberg
- Two people, One the model/rival, and one the “trainer” (swapped regularly)
- Model/Rival was to answer questions given on the same/different concept, and was to answer correctly or incorrectly
- “trainer” was to ask set questions, and give correct punishment (“NO!”), or reinforcement (Giving object)
- Alex was allowed to intervene with his “rival” when he wanted to.
What is the concept being studied in Pepperberg?
the concept of Same/different
Explain the Concept being studied in Pepperberg
Same/different is using symbols (in this case vocal for Alex) to show understanding of similarities in objects, and oddity from objects.
What is the psychology being investigated in Pepperberg?
- Social learning theory
- Operant conditioning (mainly reward given here)
What is the aim of Pepperberg?
To test whether an avian subject, such as an African Grey Parrot, can use vocal labels to demonstrate symbolic understanding of the concept of same/different
Hypothesis of Pepperberg
(not specifically said in the study)
- There will be a difference to how Alex responds to familiar, vs novel objects.
Sampling method in Pepperberg
Opportunity
What did Alex the parrot know prior to the Pepperberg study?
80 different objects of various shapes, colours and materials.
Vocal labels for:
- Five colours: green, rose, blue, yellow, grey
- Various shapes (2, 3, 4, 5 cornered shapes)
- Four materials - wood, hide, paper, cork
What were Alex the parrot’s living conditions like? (3)
- Was allowed free in the Lab, and able to go elsewhere with vocal request for 8 hours per day
- Slept in a wire cage during sleep hours
- food and water available at all times - eg. standard seed mix. Fresh fruit, vegetables etc. were available on vocal request
What type of study and experimental design was used for Pepperberg?
Case study
(therefore repeated measures)
What were the 3 possible correct response categories Alex could answer in the Pepperberg study?
- Matter (mah mah)
- Colour
- Shape
What were the two potential questions Alex could be askes that are relevant to the Pepperberg study procedure?
- What’s same?
- What’s Different?
What was Alex’s reward for answering a question correctly?
- Given the objects, or was allowed to vocalise a request for something different (positive reinforcement)
What was Alex’s punishment for answering a question incorrectly?
- Experimenter shouts “No!” (Positive punishment)
- Experimenter takes objects out of sight (negative punishment)
What were signs that Alex was getting bored in the Pepperberg study?
- Stops answering questions
- Start preening
- Other vocal requests (eg. “I wanna go X”)
How many times a week did training take place for Alex the Parrot in the Pepperberg study?
2 - 4 times per week
How long did training procedures last for Alex in the Pepperberg study?
5 minutes to 1 hour
