How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to surprise is information.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Psychology

the brief, involuntary reaction to an event that violates expectation, marked by raised brows and widened eyes.

The brief, involuntary reaction a person has to an event that violates what they expected, marked by raised brows, widened eyes, and a momentary pause before attention reorients. Darwin's 1872 The Expression of the Emotions in Man and Animals described the facial signs of astonishment and surprise and argued they recur across cultures and species; Ekman's 1992 An argument for basic emotions later placed surprise among a small set of basic emotions with distinct expressions and physiology. The referent here is a felt state in a person, brief and read from facial and bodily signs, not a number attached to an unlikely message or a tension built into a melody.[1][2]

Unit
A single episode of the emotion in a person, brief and event-triggered
Recovery means
The reaction subsides within seconds as attention reorients to the unexpected event
Measured by
Assessed by facial coding, self-report, and physiological signs such as startle and orienting responses

Information theory

the negative logarithm of an outcome's probability, measuring how unexpected it is, so rarer events carry more.

The quantity that measures how unexpected a particular outcome is, defined as the negative logarithm of its probability, so that rarer events carry more of it. Shannon's 1948 A Mathematical Theory of Communication introduced this self-information as the log-inverse of an event's probability and built the notion of entropy on its average; Tribus's 1961 Thermostatics and Thermodynamics gave the quantity the name surprisal. The referent is a number computed from a probability, scaled in bits or nats, not a person's startled reaction or a listener's response to a melodic turn.[3][4]

Unit
The information content of one outcome, in bits (log base 2) or nats
Recovery means
Not applicable
Measured by
Computed as minus the logarithm of an outcome's probability under a specified model

Music theory and aesthetics

A departure from a listener's expectation

The effect of a passage of music that departs from what a listener has been led to expect, as when a melody or harmony resolves in an unforeseen way. Meyer's 1956 Emotion and Meaning in Music argued that musical meaning and feeling arise when the flow of a piece delays, blocks, or diverts an expected continuation; Huron's 2006 Sweet Anticipation set out a psychological theory of how expectation and its violation shape a listener's response. The referent is a property of a musical passage in relation to a listener's expectations, described in tension and resolution, not a facial reaction or a probability computed from a message.[5][6]

Unit
A moment in a musical passage that departs from what was expected
Recovery means
Not applicable
Measured by
Studied through music analysis and listener experiments on expectation and its violation
