  • (20) Concentrations of cytochromes a, a(3), b, and c(+c(1)) increased during germination, outgrowth, and vegetative growth, but that of cytochrome o was highest in dormant spores.

Extinct


Definition:

  • (a.) Extinguished; put out; quenched; as, a fire, a light, or a lamp, is extinct; an extinct volcano.
  • (a.) Without a survivor; without force; dead; as, a family becomes extinct; an extinct feud or law.
  • (v. t.) To cause to be extinct.

Example Sentences:

  • (1) The stages of mourning involve cognitive learning of the reality of the loss; behaviours associated with mourning, such as searching, embody unlearning by extinction; finally, physiological concomitants of grief may influence unlearning by direct effects on neurotransmitters or neurohormones, such as cortisol, ACTH, or norepinephrine.
  • (2) The effect upon ethanol responding was found not to resemble a pattern of extinction, but rather was best described as a general overall reduction in responding.
  • (3) In a recent study, Orr and Lanzetta (1984) showed that the excitatory properties of fear facial expressions previously described (Lanzetta & Orr, 1981; Orr & Lanzetta, 1980) do not depend on associative mechanisms; even in the absence of reinforcement, fear faces intensify the emotional reaction to a previously conditioned stimulus and disrupt extinction of an acquired fear response.
  • (4) We conclude that the procedure used in this study is a non-intrusive intervention that is an extension of the current literature pertaining to sensory extinction.

  • (7) However, during massed testing, all subjects trained with response contingent CS termination showed an overall extinction influence, which was most pronounced in the medial subgroup, although the laterals showed frequency control as well.
