Liquid-crystal displayA liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden: preset words, digits, and seven-segment displays (as in a digital clock) are all examples of devices with these displays.
Affect measuresAffect measures (measures of affect or measures of emotion) are used in the study of human affect (including emotions and mood), and refer to measures obtained from self-report studies asking 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.
Display rulesDisplay rules are a social group or culture's informal norms that distinguish how one should express themselves. They can be described as culturally prescribed rules that people learn early on in their lives by interactions and socializations with other people. They learn these cultural standards at a young age which determine when one would express certain emotions, where and to what extent. Emotions can be conveyed through both non-verbal interactions such as facial expressions, hand gestures and body language as well as verbal interactions.
Love and hate (psychoanalysis)Love and hate as co-existing forces have been thoroughly explored within the literature of psychoanalysis, building on awareness of their co-existence in Western culture reaching back to the “odi et amo” of Catullus, and Plato's Symposium. Ambivalence was the term borrowed by Sigmund Freud to indicate the simultaneous presence of love and hate towards the same object. While the roots of ambivalence can be traced back to breast-feeding in the oral stage, it was re-inforced during toilet-training as well.
