Generally,in anatomical studies of object recognition deficits,________ posterior lesions are associated with ________ agnosia.
A)left hemisphere / apperceptive
B)left hemisphere / associative
C)right hemisphere / apperceptive
D)right hemisphere / associative

Accepted Answer

The answer of Generally,in anatomical studies of object recognition deficits,________...

Question 3

Which of the following statements does NOT explain why some patients are visually agnosic for living (animate)things versus nonliving (inanimate)things?
A)Knowledge about different categories of objects may be represented in different parts of the brain.
B)Inanimate objects may activate kinesthetic representations that animate objects do not.
C)Animate objects may share more visual features than inanimate objects.
D)There are more familiar animate objects in the environment than inanimate objects.

Accepted Answer

The distinction between animate and inanimate object recognition does not depend on the familiarity or quantity of objects in the environment but rather on how different categories of objects are processed and represented in the brain, their visual features, and possibly the activation of different cognitive representations.

Question 4

Which of the following visual object properties best illustrates the concept of a visually invariant property?
A)The context in which an object appears
B)Shading on an object's surface
C)The major and minor axes of an object
D)The spatial orientation of an object

Accepted Answer

The major and minor axes of an object are a visually invariant property because they remain constant regardless of the orientation of the object. This means that even if the object is rotated or viewed from a different angle, its major and minor axes will remain the same. The other options - context, shading, and spatial orientation - are not visually invariant properties because they can change depending on the viewing conditions or the properties of the environment.

Question 5

According to ________ theories of object recognition,when one sees an object such as a bicycle,recognition depends on the ability to detect properties that do not depend on specific viewing conditions.
A)view-invariant
B)viewer-centered
C)feature analysis
D)perceptual categorization

Accepted Answer

View-invariant theories suggest that object recognition is not affected by changes in perspective or viewing conditions, and instead depend on detecting properties that remain constant across different views or situations. This means that even if we see a bicycle from different angles or in different lighting conditions, we are still able to recognize it as a bicycle because of its intrinsic features. Viewer-centered theories, on the other hand, argue that recognition depends on the viewer's perspective and specific viewing conditions. Feature analysis theories and perceptual categorization theories are also relevant to object recognition, but they do not specifically address the issue of viewpoint invariance.

Question 6

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.
A)view-dependent
B)object-centered
C)recognition-by-parts
D)semantic categorization

Accepted Answer

View-dependent theories of pattern perception suggest that recognition occurs by matching the stimulus to stored representations of specific views or angles of an object.

Question 7

Warrington (1985)proposed an anatomical model of the cognitive operations necessary to explain object recognition.The first stage in this model involves the detection and categorization of visually invariant information,which occurs in the ________ hemisphere;the second stage involves the semantic categorization of visual input,which occurs in ________ hemisphere(s).
A)left / the right
B)left / both the left and right
C)right / the left
D)right / both the left and right

Accepted Answer

Warrington's model proposes that the first stage of object recognition involves the detection and categorization of visually invariant information, which occurs in the right hemisphere. The second stage involves the semantic categorization of visual input, which occurs in the left hemisphere. Therefore, the correct choice would be C, which states that the first stage occurs in the right hemisphere and the second stage occurs in the left hemisphere.

Question 8

________ is a deficit in the ability to recognize faces that cannot be directly attributed to deterioration in intellectual function.
A)Apraxia
B)Apperceptive agnosia
C)Prosopagnosia
D)Synesthesia

Accepted Answer

Prosopagnosia is a specific type of visual agnosia where individuals have difficulty recognizing faces despite having intact intellectual function. Apraxia refers to difficulty in performing purposeful movements, not recognition of faces. Apperceptive agnosia refers to difficulty in perceptual processing and recognition of objects, not specifically faces. Synesthesia is a neurological condition where stimulation of one sensory modality leads to automatic, involuntary experiences in another modality.

Question 9

________ is to ________ as face recognition is to object recognition.
A)Agnosia / prosopagnosia
B)Prosopagnosia / agnosia
C)Alexia / agnosia
D)Agnosia / alexia

Accepted Answer

Prosopagnosia is a specific type of agnosia that refers to the inability to recognize faces, whereas agnosia more broadly refers to the inability to recognize objects. Therefore, the relationship between face recognition and object recognition is best likened to the relationship between prosopagnosia and agnosia.

Question 10

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)Apperceptive agnosia
B)Associative agnosia
C)Synesthesia
D)Prosopagnosia

Accepted Answer

Apperceptive agnosia is a form of visual agnosia where there is impairment in recognizing objects due to a deficit in early visual processing, such as perception and integration of visual features. The patient's difficulty in judging whether two pictures represent the same object indicates a deficit in recognizing objects at a basic level, which is consistent with apperceptive agnosia. Associative agnosia, on the other hand, is characterized by difficulty in recognizing objects despite intact perception, but the patient usually has no difficulty in matching or identifying objects from different views. Synesthesia is a neurological condition where one sensory experience (e.g., color) is involuntarily perceived in response to another sensory experience (e.g., sound), and it is not related to agnosia. Prosopagnosia, also known as face blindness, is a specific type of agnosia where the patient has difficulty in recognizing familiar faces, but they usually have no problem recognizing objects.

Question 11

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
A)viewer-centered object recognition.
B)object constancy.
C)perceptual categorization.
D)property-based organization.

Accepted Answer

Object constancy refers to the ability to recognize an object as the same, despite changes in its appearance or context. In this case, the agent recognized the green car as the same one, despite seeing it in different locations and under different circumstances. This suggests that she has an understanding of object constancy. The other options do not fully explain the agent's ability to recognize the car under different circumstances.

Question 12

One limitation of view-dependent theories of object recognition is that
A)such an approach is based on the perception of geons in visual objects.
B)separate templates must be generated and stored for each different view of a given object.
C)this approach argues that recognition depends on decomposing a scene or object into its constituent parts.
D)this approach is based on the idea that object recognition depends on the detection of invariant stimulus properties,such as symmetry.

Accepted Answer

View-dependent theories of object recognition require separate templates for each view of a given object, which can be computationally expensive and limit generalization to new or unfamiliar views of the object.

Question 13

Patients with ________ have a deficit in recognizing visually presented objects due to problems in the ventral stream.
A)prosopagnosia
B)acquired alexia
C)associative agnosia
D)apperceptive agnosia

Question 14

A person with apperceptive visual agnosia has difficulty in recognizing drawings of familiar objects,such as an apple.If she were asked to imagine an apple rather than to inspect a picture of an apple,you would expect to find that
A)she can generate visual images normally because agnosia does not affect internally generated information.
B)she has great difficulty in generating visual images as well as visual perception because the two skills share common brain regions.
C)she can generate visual images correctly and easily,but she cannot recognize them because of a memory deficit.
D)she has great difficulty with generating images of faces but not other kinds of objects.

Accepted Answer

The answer of A person with apperceptive visual agnosia has...

Question 15

________ is the ability to recognize an object under many different viewing conditions and in many different contexts.
A)Ensemble coding
B)Object constancy
C)Apperceptive agnosia
D)Geon perception

Accepted Answer

Object constancy refers to the ability to recognize an object despite changes in its appearance or lighting conditions. Ensemble coding refers to the ability to perceive groups of objects as a whole. Apperceptive agnosia is a deficit in recognizing objects due to a difficulty in perceptual processing. Geon perception refers to the ability to perceive simple shapes as three-dimensional objects.

Question 16

According to Warrington's model,patients with left posterior lesions should be particularly impaired in
A)recognizing the visually invariant properties of objects.
B)linking visual inputs to knowledge in long-term memory.
C)matching different views of an object as representing the same item.
D)segmenting a complex drawing into its component parts.

Accepted Answer

Warrington's model suggests that patients with left posterior lesions have difficulty linking visual inputs to knowledge stored in long-term memory, affecting their ability to recognize objects based on visual information.

Question 17

________ is characterized by difficulty in matching pictures of the same object taken from different vantage points.
A)Anomia
B)Alexia
C)Apperceptive agnosia
D)Associative agnosia

Accepted Answer

Difficulty in matching pictures of the same object taken from different vantage points is a common feature of apperceptive agnosia. Anomia is characterized by difficulty in recalling the names of objects or people, while Alexia refers to difficulty in reading. Associative agnosia is characterized by difficulty in recognizing objects despite intact visual processing abilities.

Question 18

With regard to perception,the term feature refers to
A)the most important aspect of a figure,such as its identity or name.
B)a complex pattern of sensory stimulation,such as a face or word.
C)any combination of elements that requires attention for processing,such as the conjunction of color and shape.
D)a fundamental component of a visual pattern,such as edge orientation or color.

Accepted Answer

The term feature in perception refers to a fundamental component of a visual pattern, such as edge orientation or color. This is because features are the basic building blocks of perception, and they combine to create more complex patterns or objects that we recognize. A feature can be thought of as a simple visual element that contributes to our overall perception of an object or scene.

Question 19

Humphreys and Riddoch (1994)described a patient with a syndrome they called integrative agnosia,which was characterized by difficulty in
A)linking visual percepts to long-term knowledge about objects.
B)combining parts of objects into coherent whole percepts.
C)drawing and copying pictures of objects.
D)matching different view of an objects as representing the same item.

Accepted Answer

Integrative agnosia is characterized by difficulty in combining parts of objects into coherent whole percepts, as described by Humphreys and Riddoch (1994).

Question 20

In fMRI studies,when a stimulus is repeated,the BOLD response is ________ for the second presentation compared to the first.This is known as the ________.
A)lower / repetition enhancement effect
B)lower / repetition suppression effect
C)higher / repetition enhancement effect
D)higher / repetition suppression effect

Accepted Answer

In fMRI studies, when a stimulus is repeated, the BOLD response is lower for the second presentation compared to the first. This is known as the repetition suppression effect.
