Questions from this subtopic
Each one with the model answer underneath.
- 1
What was the aim of Haber and Levin's (2001) study?
Model answer
Haber and Levin aimed to find out whether knowing an object's usual size helps people judge how far away it is. The study also tested whether size and distance are perceived independently.
- 2
Who took part in Haber and Levin's study?
Model answer
The participants were a small sample of male university students with good eyesight.
- 3
What types of object did Haber and Levin use?
Model answer
Some objects were familiar and always a standard size. Others were familiar objects that come in many sizes. The rest were unfamiliar geometric shapes.
- 4
Describe the procedure of Haber and Levin's study.
Model answer
Participants first estimated the size of familiar objects from memory. Participants then estimated the distances of objects placed at different points in a large outdoor field.
- 5
What did Haber and Levin find?
Model answer
Distance estimates were generally accurate. Estimates for familiar objects of a standard size were more accurate than estimates for the unfamiliar shapes.
- 6
What did Haber and Levin conclude?
Model answer
Knowing the familiar size of an object can help a person judge its distance. Distance can also be judged from other cues in the scene, independently of an object's size.
