Harm avoidance is a temperament assessed in the Temperament and Character Inventory (TCI), its revised version (TCI-R) and the Tridimensional Personality Questionnaire (TPQ) and is positively related to the trait neuroticism and inversely to extraversion in the Revised NEO Personality Inventory and the Eysenck Personality Questionnaire. [3]
Such studies have demonstrated associations between single brain regions' neural responses to certain tasks and individual differences in a wide range of sociocognitive functioning, such as approach/avoidance behavior, [27] sensitivity to rejection, [28] conceptions of the self, [29] [30] and susceptibility to persuasive messages. [31]
The neural circuit responsible for expressing signaled avoidance behavior is the same that controls extinction of fear responses. The presentation of the aversive stimulus activates neurons in the central amygdala which project to the periaqueductal gray region to elicit a fear-motivated motor response.
Harm avoidance was positively correlated with N-Anx and negatively with sociability. Zuckerman and Cloninger contended that Harm Avoidance is a composite dimension comprising neurotic introversion at one end and stable extraversion at the other end.
Therefore, self-avoidance is necessary for proper neuronal wiring and postnatal development and, together with neuronal tiling (heteroneuronal avoidance), is a crucial spacing mechanism for patterning neural circuits that results in complete and nonredundant innervation of sensory or synaptic space.
It is a multifaceted behavioral construct that includes thrill seeking, novelty preference, risk taking, harm avoidance, and reward dependence. The novelty-seeking trait is considered a heritable tendency of individuals to take risks for the purpose of achieving stimulation and seeking new environments and situations that make their experiences ...
Catherine Hartley is an American psychologist and an Associate Professor of Psychology within the Department of Psychology and Center for Neural Science at New York University in New York City. Hartley's research explores how brain development impacts the evaluation of negative experiences, decision-making, and motivated behavior.
The neural crest is responsible for a large part of early development in vertebrates. It is specifically responsible for development of the peripheral nervous system (PNS). The neural-crest stem cells split from the neural tube as it closes, and nociceptors grow from the dorsal part of this neural-crest tissue. They form late during neurogenesis.
