Which theory assumes that top-down processing can influence a person's absolute threshold for a particular stimulus?
Signal detection theory assumes that top-down processing can influence a person's absolute threshold for a particular stimulus. This theory suggests that factors such as individual differences in attention and expectation can impact an individual's ability to detect a stimulus in a noisy environment.

What is the difference between theory of absolute advantage and a theory of comparative advantage?
Those theories both refer to international trade, however absolute advantage was mentioned earlier. According to it, a trade between 2 countries is possible only if one has absolute advantage (produces a good with less costs or with less time) and other has absolute disadvantage in producing that good but at the same time it must have an absolute advantage in producing the secong good. If a country produces a good better (cheaper/faster), it would specialize on it and export. Theory assumes that only 2 counties and 2 goods exist, no other costs except for labour are taken into account.
Which philosopher believed truth was absolute and used questioning techniques as a method of teaching?
Socrates believed in the idea of absolute truth and used questioning techniques, known as the Socratic method, to encourage critical thinking and self-discovery in his students. This approach involved asking probing questions to help individuals examine their beliefs and values to arrive at deeper, more reasoned conclusions.
What are the criticisms of absolute income hypothesis?
Critics argue that absolute income hypothesis overlooks other important factors influencing consumption, such as psychological and social influences. Additionally, it assumes individuals make rational decisions based solely on their income level, ignoring other motivations for consumption behavior. Lastly, it may not account for variations in consumer preferences and behavior across different income groups.
What best describes inductive resoning?
Inductive reasoning is a process of drawing generalized conclusions based on specific observations or evidence. It involves making a hypothesis or generalization that is likely but not guaranteed to be true. This type of reasoning is probabilistic and does not provide absolute certainty.
What does contextual theory of meaning mean?
The contextual theory of meaning suggests that the meaning of words and phrases is determined by the context in which they are used. This means that the interpretation of language involves considering not only the words themselves, but also the surrounding circumstances and background information. It emphasizes that meaning is not fixed or absolute, but can vary depending on the context in which communication takes place.
What is the conclusion on different between different threshold and absolute threshold?
The difference between differential threshold and absolute threshold lies in their definitions and applications in sensory perception. The absolute threshold refers to the minimum intensity of a stimulus needed for detection by the senses, while the differential threshold (also known as the just noticeable difference, or JND) measures the smallest detectable difference between two stimuli. In essence, the absolute threshold focuses on the point of detection, whereas the differential threshold emphasizes the ability to perceive changes in stimulus intensity. Both concepts are vital in understanding sensory processing and perception.
What is the Point at which a person can detect a stimulus 50 percent of time it is presented?
The point at which a person can detect a stimulus 50% of the time it is presented is known as the absolute threshold. This threshold represents the minimum intensity of a stimulus needed to detect it half of the time. It is often used in psychology to study perception and sensory processing.
What is the perceptual threshold for vision?
The absolute threshold is the smallest amount of light that a person can detect. The human absolute threshold we can detect is a candle flame at 30 miles away.
What is the difference between absolute threshold and difference threshold?
absolute threshold is the lowest level that a person will feel sensation differential threshold is the minimal difference that a person can detect between two similar stimuli For example a change in volume in certain frequencies would be crossing the absolute threshold, how much that change would need to be for someone to detect it would be dealing with the difference threshold.
What is a brief auditory or visual signal that occurs below the absolute threshold for that sense?
A brief auditory or visual signal that occurs below the absolute threshold for that sense is known as a subliminal stimulus. These stimuli are presented in such a way that they are below our conscious awareness but may still influence our perception or behavior.
The absolute threshold for hearing is arbitrarily defined?
The absolute threshold for hearing is defined as the lowest intensity of a sound that can be detected by an individual at least 50% of the time. While specific measurement criteria may vary, this threshold serves as a practical reference point for understanding auditory perception.
Range of absolute threshold of smell?
half a mile
What is absolute threshold?
Absolute threshold is the smallest level of energy required by an external stimulus to be detectable by the human senses, including vision, hearing, taste, smell and touch
What is an example of absolute threshold?
An example of an absolute threshold is the minimum amount of light that a person can detect in a dark room. This is the point at which the person first becomes aware of the presence of light.
When you notice the soft sound of rain on the roof it has crossed a perceptual line called your threshold for detecting an auditory signal A absolute B relative C determinant D defining?
A. absolute. The threshold for detecting an auditory signal is known as the absolute threshold, which refers to the minimum intensity of a sound that can be detected by the human ear.
Can you give me Examples of absolute threshold?
An absolute threshold refers to the minimum intensity of a stimulus that can be detected by an observer. For example, the absolute threshold for hearing is the faintest sound that a person can hear, typically measured at around 0 decibels. In vision, it might be the smallest amount of light that can be perceived, such as a single candle flame at a distance of about 30 miles on a dark night. Similarly, the absolute threshold for taste is the smallest concentration of a substance that can be detected, like a teaspoon of sugar in two gallons of water.
What are absolute threshold in vision?
The absolute threshold of vision is being able to see a candle flame from 30 miles on a clear dark night. This the absolute threshold under normal conditions and they vary according to the level and nature of ongoing sensory stimulation and varies from person to person and moment to moment.
