Duration of extinction trials as a determinant of instrumental extinction in terrestrial toads (Rhinella arenarum)
(Springer Heidelberg, 2018-01)
Instrumental learning guides behavior toward resources. When such resources are no longer available, approach to previously reinforced locations is reduced, a process called extinction. The present experiments are concerned ...
Extinction memory in the crab Chasmagnathus: recovery protocols and effects of multi-trial extinction training
(Springer-Verlag, 2009-10)
A decline in the frequency or intensity of a conditioned behavior following the withdrawal of the reinforcement is called experimental extinction. However, the experimental manipulation necessary to trigger memory ...
Spontaneous recovery from extinction in the infant rat
(Elsevier Science, 2014-11)
Within the Pavlovian conditioning framework, extinction is a procedure in which, after conditioning, the conditioned stimulus (CS) is repeatedly presented without the unconditioned stimulus (US). During this procedure the ...
Coping between crises: Early Triassic-early Jurassic bivalve diversity dynamics
(Elsevier Science, 2011-11)
The Triassic is bounded by two of the most severe biotic crises, but nevertheless this time was, for bivalves, both a recovery and a diversification period, and a moment to fully exploit some of their evolutionary novelties. ...
PAUSES IN MULTIPLE EXTINCTION FIXED-INTERVAL REINFORCEMENT SCHEDULES WITH FIXED DURATIONS OF THE EXTINCTION COMPONENT: IMPLICATIONS FOR TIMING
(Sociedad Mexicana de Análisis de la Conducta / Mexican Society of Behavior Analysis, 2013)
On the roles of hunting and habitat size on the extinction of megafauna
(Pergamon-Elsevier Science Ltd, 2017-02)
We study a mechanistic mathematical model of extinction and coexistence in a generic hunter-prey ecosystem. The model represents typical scenarios of human invasion and environmental change, characteristic of the late ...
Post-learning sleep transiently boosts context specific operant extinction memory
(Frontiers Research Foundation, 2017)
Operant extinction is learning to supress a previously rewarded behavior. It is known to
be strongly associated with the specific context in which it was acquired, which limits
the therapeutic use of operant extinction ...
Diversification events and the effects of mass extinctions on Crocodyliformes evolutionary history
(2015)
The rich fossil record of Crocodyliformes shows a much greater diversity in the past than today in terms of morphological disparity and occupation of niches. We conducted topology-based analyses seeking diversification ...
