Perception, study questions
These are questions meant to help guide your reading of the chapters and your preparation for quizzes. You can team up with your classmates and turn it in as a group. Your answers will be graded based on completion not accuracy. Feedback will be sent to you shortly after submission.
1. What is overt spatial attention, what is covert spatial attention, and what is featurebased attention? Define and explain each of them using an example.
2. What are the two types of covert attention? Define and explain each of them using an example. In an experiment that examines how covert attention facilitates response time, what kind of cues should experimenters use for each of these two types of covert attention?
3. How did Carrasco and colleagues (2004) demonstrate that attention alters the appearance of visual stimuli?
4. Can attention change the responses of a single neuron? If so, what are the possible changes? Can attention shift the receptive field of the neuron?
5. Explain the two fMRI experiments that provided evidence for enhancement of neural activity by attention.
6. Which of the following example best fits inattentional blindness, change blindness, attentional blink, and attentional neglect? Make a one-to-one match.
- A person with a brain damage (the parietal lobe in the right hemisphere) would not be able to locate a target object if it’s in the left visual field.
- While playing ‘Find the Ball’ with your friends, you replaced a red cup with a red pepper while your friends were tracking the cup with a ball hidden under. At the end, most of your friends didn’t notice your funny prank.
- People are presented with a picture, followed by a white paper, followed by the same picture but with an item missing, followed by a white paper, followed by the original picture, and so on. The pictures had to be alternated back and forth a number of times before people can detect the difference.
- Imagine watching Halloween parade. You wanted to count how many people dressed up like superheroes. However, the number you counted is a bit less than the actual number because sometimes you missed those ‘superheroes’ who stood close behind other ‘superheroes’.
