Exam 6: Object Recognition

With regard to perception,the term feature refers to

The term gnostic unit refers to

Patients with apperceptive agnosia typically present with large scotomas or a hemianopsia.

Some researchers have argued that a specialized face-processing region can be found in the

The "what" versus "where" distinction is supported by single-cell recording studies showing that neurons in the ________ lobes have receptive fields that are almost always located in the fovea,where high-acuity vision takes place.

Why is object constancy a difficult computational problem for the visual system? Describe some potential invariances that can occur when we view the same object under different circumstances.How do view-dependent and view-invariant approaches to perception explain object constancy?

The ERP component associated with face perception is the

The patient D.F. ,studied by Goodale and Milner (1982),had severe problems with object recognition.When presented with a circular block into which a slot had been cut,

An undercover agent notices a green car parked outside her apartment building when she leaves for work at 8 a.m.Later she notices the same car in a store parking lot and becomes suspicious that she is being followed.The agent's ability to recognize the car under these two different circumstances is an example of

When a person who has learned to read proficiently subsequently develops reading problems as a result of brain injury,this deficit is called

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?

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

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

According to Farah,face perception is holistic whereas word reading is accomplished by analysis by parts.

Patients with prosopagnosia typically have difficulty recognizing

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

The statement "recognition of a visual pattern at a later time occurs only if you can match the stimulus to its exact stored representation" best describes ________ theories of pattern perception.

One critical distinction in the task of face recognition versus that of reading may be that

________ is the ability to recognize an object under many different viewing conditions and in many different contexts.

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.
