Total questions: 10

Which of the following is a fundamental concept in psychophysics?
Memory retention
Cognitive dissonance
Signal detection
Dream analysis
The difference threshold is also known as:
Sensory adaptation
Transduction threshold
Absolute threshold
Just noticeable difference (JND)
According to Weber's law, the JND is proportional to:
The intensity of the stimulus
The logarithm of the stimulus intensity
The duration of the stimulus
The type of sensory modality
The absolute threshold represents the minimum intensity of a stimulus needed to:
Produce a sensation half of the time
Produce a sensation all of the time
Be detected in a specific sensory channel half of the time
Produce a sensation at a suprathreshold level
Fechner's law proposes that the magnitude of a sensation is proportional to:
The logarithm of the stimulus intensity
The square of the stimulus intensity
The reciprocal of the stimulus intensity
The square root of the stimulus intensity
Which of the following is a psychophysical method used to determine the absolute threshold?
Method of constant stimuli
Method of constant function
Method of absolute frequency
Method of Paired association
In a psychophysical experiment, participants are asked to identify the presence or absence of a stimulus on each trial. This method is known as:
Method of limits
Signal detection theory
Difference threshold analysis
Method of adjustment
The point at which a stimulus transitions from being imperceptible to perceptible is called:
Perceptual constancy
The difference threshold
The just noticeable difference
The limen
Which sensory modality is most closely associated with the study of psychophysics?
Language processing
Audition (hearing)
Decision-making
Motor control
The relationship between the physical properties of a stimulus and our psychological experience of it is the central focus of:
Cognitive Psychology
Psychometric
Psychophysics
Psychomania
