Exam 6: Object Recognition

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?

Prosopagnosia is to alexia as ________ is to ________.

With regard to perception, the term feature refers to

________ is to ________ as face recognition is to object recognition.

Selective damage to the primary visual cortex typically leads to visual agnosia.

You, a neurologist, have just met a patient who suffered a stroke last year and is having trouble identifying objects. Could this person be experiencing visual agnosia? What tasks could you ask the patient to perform to help you determine the source of the problem?

Decoding is to encoding as ____________ is to ____________.

Tanaka and Farah (1993) used line drawings of faces and houses in a recognition task. Participants were instructed to associate houses with names of those who lived there, and to associate faces with names. During the recall portion of the task, items were presented either in isolation or in context. Which of the following best describes the findings of this study?

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

Which of the following is a brain region that would likely be implicated in processing spatial relations in an outdoor scene?

A patient's ability to represent the spatial layout of their environment has become disturbed. The patient most likely has damage in the _____ lobe.

When her telephone rings, a patient who has been diagnosed with visual object agnosia immediately picks up the receiver and answers it correctly. Why doesn't this person show any signs of an object recognition deficit in this scenario?

How can researchers use our knowledge of the visual system to maximize the decoding of brain activity? What factors currently limit decoding performance?

A patient who has difficulty matching pictures of the same object taken from different vantage points may be showing which dysfunction?

With regard to the two main output pathways from the occipital lobe, ________ is to ________ as dorsal is to ventral.

A major distinction in the study of visual agnosia is that between apperceptive visual agnosia and associative visual agnosia.

Which of the following statements does NOT explain why some patients are visually agnosic for living (animate) things versus nonliving (inanimate) things?

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?

Each of the following are factors that currently restrict our ability to decode information from the brain, EXCEPT

The results of most single-cell studies of temporal lobe neurons support the gnostic unit hypothesis.
