Impulsivity
Pathological decrease of impulse control, often encountered in ADHD and Tourette’s syndromes, that is.deletrious to self or others, and which may or may not be accompanied by feelings of guilt. There is evidence that poor impulse control turns out to be a better predictor of delinquency than IQ. See Attention deficit hyperactivity syndrome (ADHD), Continuous …
Imprinting
In ethology, a rapid early learning of identifying features of parents (filial imprinting) and/or of mating partners (sexual imprinting). Also considered to be the process by which early experience promotes the development of perceptual mechanisms. It is often restricted to a critical or sensitive period, particularly in birds.

Consonants produced along with a sudden descent of the larynx so that air is drawn back into the mouth. The drawing back of air into the mouth is referred to ‘glottalic ingressive airstream’. See Consonant, Glottal, Larynx
Implicate order
A part of the more general concept of holomovement as advanced by David Bohm (1917-1992), which deals with nature of physical reality from the viewpoint of quantum mechanics and other similar theories in physics. The concept holds that the ultimate nature of such reality is an undivided whole that is a constant state of dynamical …
Immunoglobins
Also known as antibodies, they are proteins found in the blood serum and in tissue fluids such as breast milk that are produced by B-lymphocyte cells of the immune system. Their function is to bind to substances in the body that are recognized as foreign antigens, which more often than not are other proteins on …

Immediate-early genes
Genes that are expressed rapidly (within minutes), transiently following a variety of cellular signals, and which apparently do not require protein synthesis. See Gene
Illusory contours
Boundaries of objects that are not visible, but are implied by the arrangement of line segments and other visual stimuli. The effect was first reported by Friedrich Schumann (1863-1940) who influenced the the foundation of Gestalt psychology. Evidence suggests that that the perception of illusory contours emerges about 3-4 months of age, but that this …
