A theory of perception that proposes the existence of feature detectors, cortical cells that fire only when we see certain visual stimuli such as shapes, colors of light or movement.

Feature detection theory proposes that complex stimuli are processed by first detecting and analyzing specific features or elements of the stimulus, such as lines, angles, shapes, or colors. These features are then combined to create a perception of the whole stimulus. This theory helps explain how our sensory systems can process and make sense of the vast amount of information in our environment.

What theory of perception proposes that detection of stimuli depends on a variety of factors?
Signal Detection Theory proposes that the detection of stimuli depends on both the intensity of the stimulus and the individual's psychological factors, such as motivation and expectancy. This theory suggests that perception is influenced by both the sensitivity of sensory processes and cognitive factors.
Which theory emphasizes that personal expectations and motivations influence the level of absolute thresholds?
Signal Detection Theory emphasizes that personal expectations and motivations influence the level of absolute thresholds by suggesting that an individual's sensitivity to a stimulus depends on both sensory factors and decision-making processes. This theory acknowledges that psychological factors such as expectation, motivation, and attentiveness can impact an individual's ability to detect a stimulus.
What is the signal detection theory?
Signal detection theory is a framework used to analyze decision-making in the presence of uncertainty, particularly in the context of detecting a signal (e.g., a stimulus) in the presence of noise. It considers factors such as the observer's sensitivity to the signal and their response criterion. The theory is commonly applied in psychology, neuroscience, and engineering to understand how individuals make judgments in uncertain situations.
What are the key features of Social learning Theory?
Social learning theory emphasizes the importance of observation, imitation, and modeling in learning. It suggests that individuals acquire new behaviors and knowledge through observing and imitating the actions of others. The theory also highlights the role of reinforcement and punishment in influencing behavior.
The detection of physical energy emitted or reflected by physical objects is called?
The detection of physical energy emitted or reflected by physical objects is called remote sensing. This technology is used to gather information from a distance by recording and analyzing the energy that is emitted or reflected by objects on the Earth's surface.
What theory of perception proposes that detection of stimuli depends on a variety of factors?
Signal Detection Theory proposes that the detection of stimuli depends on both the intensity of the stimulus and the individual's psychological factors, such as motivation and expectancy. This theory suggests that perception is influenced by both the sensitivity of sensory processes and cognitive factors.
Is feature detection theory object-centered or viewer-centered?
Object-centered- it was illustrated by the single-cell recording experiments with cats and straight lines.
What is a signal detection threshold?
Detection theory allows one to quantify the ability to discern between information bearing patterns and random patterns that causes confusion in the patterns. In electronics, detection theory is often called signal recovery.
What is a feature of an intrusion detection system?
Searches for features of known attacks
Which theory emphasizes that personal expectations and motivations influence the level of absolute thresholds?
Signal Detection Theory emphasizes that personal expectations and motivations influence the level of absolute thresholds by suggesting that an individual's sensitivity to a stimulus depends on both sensory factors and decision-making processes. This theory acknowledges that psychological factors such as expectation, motivation, and attentiveness can impact an individual's ability to detect a stimulus.

What theory claims that a struggle for power is a basic feature of human existence?
conflict theory
What does signal detection theory add to the ideas of sensory thresholds?
Signal detection theory applies when signal detection is more important than signal fidelity. Safety is an example of an imperative that will influence whether a sensory threshold is low or high. The penalty of a missed detection vs a false detection. Radar is designed with this in mind. Safety is not the main imperative in all biological systems, where fidelity is more important. C=capacity of channel R=information to be transmitted E=errors When R>C the problem is signal detection, and E are inevitable (see Constant False Alarm Rate) When R<C the problem is signal fidelity (eg internet) and E rate increases as R approaches C.
