In the branch of experimental psychology focused on sense, sensation, and perception, which is called psychophysics, a just-noticeable difference or JND is the amount something must be changed in order for a difference to be noticeable, detectable at least half the time. [1]
Hindsight bias is more likely to occur when the outcome of an event is negative rather than positive. [14] This is a phenomenon consistent with the general tendency for people to pay more attention to negative outcomes of events than positive outcomes.
Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" [1] or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the ...
In psychology, illusory correlation is the phenomenon of perceiving a relationship between variables (typically people, events, or behaviors) even when no such relationship exists. A false association may be formed because rare or novel occurrences are more salient and therefore tend to capture one's attention . [ 1 ]
For example, if a stimulus is tripled in strength (i.e., 3 × 1), the corresponding perception may be two times as strong as its original value (i.e., 1 + 1). If the stimulus is again tripled in strength (i.e., 3 × 3 × 1), the corresponding perception will be three times as strong as its original value (i.e., 1 + 1 + 1). Hence, for ...
"THE CAT" is a classic example of context effect. We have little trouble reading "H" and "A" in their appropriate contexts, even though they take on the same form in each word. A context effect is an aspect of cognitive psychology that describes the influence of environmental factors on one's perception of a stimulus. [1]

Examples of this could include a noticeable scar, a thick accent or a habit such as cracking their knuckles.
In psychophysics, sensory threshold is the weakest stimulus that an organism can sense.Unless otherwise indicated, it is usually defined as the weakest stimulus that can be detected half the time, for example, as indicated by a point on a probability curve. [1]
