Exam 6: Object Recognition

Three primary localized regions include face, place, and clothes areas.

Pohl 1973) conducted a study of the "what" and "where" pathways in brain-lesioned monkeys using two different tasks: a landmark discrimination task, which required a visuospatial judgment, and an object discrimination task, which required object recognition. He found that monkeys with temporal lobe lesions became severely impaired in learning the task but not the task. Monkeys with posterior parietal lesions showed the pattern of performance.

Prosopagnosia is to alexia as is to .

is to as face recognition is to object recognition.

Which of the following factors does NOT restrict our ability to decode information from the brain?

Which characteristic of brain activity is promising for the potential to decode dreams in the future?

Describe the visual system's dorsal and ventral pathways. In your answer, describe the kinds of information that are processed in each pathway and the lobes of the brain that are involved. Give an example of an experiment discussed in class or your text that supports this distinction in the visual system.

An encoding model of brain activity predicts brain activity from a given stimulus.

Patients with prosopagnosia typically have difficulty recognizing

Why do people fail to notice when the mouth and eyes of an inverted face remain upright?

After suffering from a focal brain injury, a patient has difficulty in recognizing visually presented objects, despite normal acuity and color perception. Notably, she has severe difficulty in judging whether two pictures, each showing a different view, represent the same object. What is the most probable diagnosis?

A patient like G.S. who had visual object agnosia would have difficulty in identifying an object unless

The term associative agnosia is reserved for patients who

How do receptive fields of cells in the ventral and dorsal streams differ? How do these characteristics support the functions of the ventral and dorsal streams?

According to ensemble theories of object recognition, it is possible to confuse similar-looking objects because

Humphreys and Riddoch 1994) described a patient with a syndrome they called integrative agnosia, which was characterized by difficulty in

There is some evidence for a double dissociation between agnosia for animate living) things compared to inanimate nonliving) things. Does this mean that there are distinct brain systems for representing these two categories? Why or why not?

According to Warrington's model, patients with left posterior lesions should be particularly impaired in

When a picture of a hammer is placed in front of Patient H, she is unable to identify it. How can you determine if her difficulty is in recognizing the object or in simply remembering its name?

A major source of evidence against the idea that faces are processed in a special brain region in humans is that the candidate region
