Dualism
Dualism is the idea that
STD and objective difficulty
In signal detection theory, the (shift/criterion/method of limits/ sensititvity/ method of adjustment) is a value that defines the objective difficulty with which an ideal observer could tell the difference between the presence and absence of a stimulus or the difference between two stimuli.
In signal detection theory, the sensitivity is a value that defines the objective difficulty with which an ideal observer could tell the difference between the presence and absence of a stimulus or the difference between two stimuli.
Sensation and perception
What is the difference between sensation and perception? (Essay)
Sensation is concerned with how our senses transduce energy from the world (light, sound, mechanical pressure) into neural energy. Perception is the interpretation of sensations and the assignment of meaning to them. For example, this paragraph is an array of black and white spots of light on the backs of our retinas that excites our rods and cones (sensation), but we perceive it as text that has meaning (perception).
Materialism
Materialism is the notion that
What is the difference between sensation and perception?
Binary decisions (no. 4)
If a stimulus is absent and the observer reports it as absent, this is called a
Binary decisions (no. 3)
If a stimulus is absent but the observer reports it as present, this is called a
STD and airport security
Airport security is very tight. If a traveler even jokes about a bomb, they are detained and questioned to ensure that no real terrorist threat succeeds. In terms of signal detection theory, airport security would rather have a
Difference between sensitivity and criterion
What is the difference between sensitivity and criterion in signal detection theory?
The sensitivity of a binary decision describes the distance of the peak of the two distributions (YES and NO likelihood) across a perception axis: If the maxima of the distributions are far from each other (high sensitivity), it is usually easier to make less mistakes (false YES and falso NO). The criterion describes the point of perception that marks when a subject shifts to the other answer if crossed. It can be the point where both are equally likely, or any other point.
Relation between stimulus and sensation
_____ describes the relationship between a stimulus and its resulting sensation by proposing that the JND is a constant fraction of the stimulus intensity.
Weber’s law describes the relationship between a stimulus and its resulting sensation by proposing that the JND is a constant fraction of the stimulus intensity.
STD visualization
Internal threshold in STD
In signal detection theory the (shift/criterion/method of limits/sensitivity/method of adjustment) is an internal threshold that is set by the observer.
In signal detection theory, the criterion is an internal threshold that is set by the observer.
Binary decisions (no. 2)
If a stimulus is present and the observer reports it as absent, this is called a
Matter and consciousness
The idea that all matter has consciousness is known as
Founder of psychophysics
(Wundt/Berkeley/Fechner/Weber/Plato) is the founder of psychophysics.
Fechner
Meaning and sensation
(Perception/Distortion/Observation/Adaptation) is the art of giving meaning to a detected senesation.
Perception
Binary decisions (no. 1)
If a stimulus is present and the observer reports it as present, this is called a
Stevens power law
Stevens’ power law describes the relationship between a
(Fechner’s law/ Steven’s power law/ Weber’s law / Fourier analysis / signal detection theory) describes the relationship between a stimulus and its resulting sensation by proposing that the JND is a constant fraction of the stimulus intensity.
Webers law
Psychophysical methods (no. 4)
If you are asked to taste a lemon and then adjust a light until it is as bright as the lemon is sour, you have been asked to engage in
Stimuli and private experience
_____ is the ability to detect a stimulus and, perhaps, to turn that detection into a private experience.
The method of ______
requires the observer to alter the strength of a stimulus until it matches some criterion.
Weber’s Law
Weber proposed that the smallest change in a stimulus that can be detected is a(n) _____ proportion of the stimulus level.
