Affect measures Affect measures One common way of studying human emotion is to obtain self-reports from participants to quantify their current feelings or average feelings over a longer period of time.

Even though some affect measures contain variations that allow assessment of basic predispositions to experience a certain emotion, tests for such stable traits are usually considered to be personality tests. The Affective Slider is an empirically-validated digital scale for the self-assessment of affect composed of two slider controls that measure basic emotions in terms of pleasure and arousal, which
Electrical length Electrical length In telecommunications and electrical engineering, electrical length (or phase length) refers to the length of an electrical conductor in terms of the phase shift introduced by transmission over that conductor at some frequency. Depending on the specific usage, the term "electrical length" is used rather than simple physical length to incorporate one or more of the following three concepts: The first usage of the term "electrical length" assumes a sine wave of some frequency, or at least a narrowband waveform centered around some frequency "f". The sine wave will repeat with a period of "T" = 1/"f". The
