Question 1

In an experiment by Biederman, the recognition of objects was more difficult when lines were deleted at

Accepted Answer

In Biederman's experiment, the recognition of objects became more difficult when lines were deleted at vertices, which supports a structural theory of object recognition. This theory suggests that objects are recognized based on the arrangement of their simpler component shapes, which are connected at vertices.

Question 2

Emphasizing distinctive features when teaching young children to recognize letters

Accepted Answer

Emphasizing distinctive features when teaching young children to recognize letters aids in their ability to differentiate between letters later on, reducing confusion and mistakes. This approach focuses on the unique aspects of each letter, making it easier for children to identify and remember them.

Question 3

In an experiment by Phillips, subjects had to decide whether two checkerboard patterns were the same or different. They could not make a template match

Accepted Answer

Phillips' experiment on visual pattern recognition demonstrated that subjects struggle to match checkerboard patterns under several conditions: when patterns are displayed in different screen locations, after the decay of visual information in memory, and if there's a delay of more than 0.5 seconds between presentations. These factors all contribute to difficulties in template matching, indicating the limitations of visual short-term memory and the importance of spatial and temporal proximity for accurate pattern recognition.

Question 4

If I were to describe my friend Bob by saying he has dark hair, blue eyes, and he's very tall, which kind of theory would I be using?

Accepted Answer

Feature theory is correct because it involves describing an object (or person, in this case) based on a set of characteristics or features, such as hair color, eye color, and height.

Question 5

Egeland taught kindergarten children to distinguish effectively between confusable letter pairs by emphasizing

Accepted Answer

Egeland's method focuses on teaching children to recognize letters by emphasizing their distinctive features, which are the aspects that differentiate one letter from another. This approach helps children distinguish between letters that look similar by highlighting the unique characteristics of each letter.

Question 6

The importance of distinctive features in pattern recognition is demonstrated by the finding that people were

Accepted Answer

Distinctive features in caricatures exaggerate unique facial characteristics, making them easier and faster to recognize compared to accurate line drawings.

Question 7

The skeleton structure of animals can best be described by a

Accepted Answer

The structural theory best describes the skeleton structure of animals as it focuses on the arrangement and organization of parts within a system, which is applicable to the anatomical structure of skeletons.

Question 8

The results of the Phillips (1974) study discussed in your text indicates that

Accepted Answer

The template model is a theory of memory that proposes that memories are stored as exact copies of the original stimuli. The feature model is a theory of memory that proposes that memories are stored as a collection of features that are extracted from the original stimuli. The Phillips (1974) study found that the template model was a better predictor of performance on a recognition task than the feature model, which suggests that the template model may describe events within the sensory store.

Question 9

Which of the following models does not belong?

Accepted Answer

The answer of Which of the following models does not...

Question 10

A major difference between a feature theory and a template theory is

Accepted Answer

Template theories suggest that an object is recognized as a whole, or a single unit, rather than being broken down into its constituent features. This contrasts with feature theories, which propose that objects are recognized by analyzing their individual features and the relationships between those features.

Question 11

The duration of the visual sensory store is approximately

Accepted Answer

The visual sensory store, often referred to as iconic memory, has a duration of approximately 250 milliseconds (msec). This brief period allows the visual system to retain information long enough for it to be processed further.

Question 12

A method for distinguishing between real people and intelligent computer programs is to require both to recognize

Accepted Answer

CAPTCHAs (Completely Automated Public Turing test to tell Computers and Humans Apart) often use mangled words that humans can recognize and interpret, but that present significant challenges for computer programs. This method leverages the human brain's ability to decipher distorted or obscured text, a task that, until recently, has been difficult for AI and computer programs to replicate with high accuracy.

Question 13

A set of proposed features is usually evaluated by

Accepted Answer

The answer of A set of proposed features is usually...

Question 14

According to Gibson's feature theory, features should remain unchanged despite changes in

Accepted Answer

Gibson's feature theory posits that the basic features of objects remain constant and recognizable despite variations in brightness, size, and perspective. This theory suggests that our perception of an object's basic features does not change even when the object is viewed under different conditions.

Question 15

Template theories

Accepted Answer

Template theories suggest that the human brain matches incoming sensory information to a set of templates or patterns that it has stored. This process does not involve analyzing specific features or how they are connected but rather involves a direct comparison to recognize patterns as a whole.

Question 16

Which theory seems to best describe the contents of the sensory store?

Accepted Answer

Template theory best describes the contents of the sensory store, as it suggests that the sensory store holds unanalyzed sensory information in a template or unaltered form, which aligns with the concept of sensory memory being a brief, exact copy of sensory information.

Question 17

Biederman's component model is an example of

Accepted Answer

Biederman's component model, also known as the Recognition-by-Components (RBC) theory, is a structural model. It proposes that objects are recognized by the arrangement of simple 3D shapes called geons. These geons can be combined in various ways to form countless different objects, emphasizing the model's structural aspect rather than relying on features or templates.

Question 18

The theory that describes patterns by listing their parts is

Accepted Answer

Feature theory describes patterns by listing their parts, focusing on the individual features that make up a pattern.

Question 19

Which theory states that we compare patterns with each other and measure how much they overlap?

Accepted Answer

Template theory posits that we recognize patterns by comparing them to templates or prototypes in our memory, essentially measuring how much a new pattern overlaps with existing templates.

Question 20

Structural theories of pattern recognition

Accepted Answer

Structural theories of pattern recognition are indeed extensions of feature theories. They not only consider the features themselves but also the relationships among these features, providing a more comprehensive understanding of how patterns are recognized.
