    • Laborda Rojas, Mario; Miguez, Gonzalo; Polack, Cody W.; Miller, Ralph R. (2012)
      Research using non-human animals as experimental subjects to understand human behavior have been based on the Darwinian notion of continuity between species. In this framework, we find analogous models to understand human ...
    • Alfaro, Felipe; Mallea, Jorge; Laborda Rojas, Mario; Cañete, Aracelli; Míguez Cavieres, Gonzalo (Elsevier, 2018)
      An occasion setter (OS) is a stimulus or context with the capacity to disambiguate an ambiguous conditioned stimulus (CS). Previous research has shown that OSs share some features with regular Pavlovian CSs. Amongst them, ...
    • Laborda Rojas, Mario; Polack, Cody W.; Miguez, Gonzalo; Miller, Ralph R. (Elsevier, 2014)
      Background and objectives: Recent data indicate that extinguished fear often returns when the testing conditions differ from those of treatment. Several manipulations including extensive extinction training, extinction ...
    • Miguez, Gonzalo; Laborda Rojas, Mario; Miller, Ralph R. (Elsevier, 2014)
      This article reviews situations in which stimuli produce an increase or a decrease in nociceptive responses through basic associative processes and provides an associative account of such changes. Specifically, the ...
    • Miller, Ralph R.; Laborda Rojas, Mario; Polack, Cody W.; Míguez Cavieres, Gonzalo (Springer, 2015)
      Exposure to a cue alone either before (i.e., latent inhibition treatment) or after (i.e., extinction) the cue is paired with an unconditioned stimulus results in attenuated conditioned responding to the cue. Here we report ...
    • Laborda Rojas, Mario; Witnauer, James E.; Miller, Ralph R. (Springer, 2011)
      Rats were used in a lick suppression preparation to assess the contribution of conditioned-stimulus (CS)– context and context–unconditioned-stimulus (US) associations to experimental extinction. Experiment 1 ...
    • Lira Ampuero, Daniela; Bustamente Alvarez, Javier; Quezada Scholz, Vanetza; Miguez Cavieres, Gonzalo; Laborda Rojas, Mario; Bustamente Alvarez (Neuropsicología Cl., 2016)
      The present article constitutes a chronicle of the Laboratorio de Psicologia Experimental: Prof. Ronald Betancourt Mainhard of the Psychology Department of the Universidad de Chile, in the 1999-2016 period. Using the ...
    • Betancourt Mainhard, Sigmond; Corada Luis, Leonor; Dominichetti Camus, Juan; Laborda Rojas, Mario; Martínez Miranda, Gabriel; Miguez Cavieres, Gonzalo (COLEGIO OFICIAL DE PSICOLOGOS DE ASTURIAS, 2008-05)
      The Pavlovian analysis of drug tolerance describes how the contexts of drug administration participate in the elicitation of compensatory conditioned responses that are, at least partly, responsible for tolerance. Findings ...
    • Quezada Scholz, Vanetza; Laborda Rojas, Mario; Díaz, Marcela C.; Navarro, Víctor M.; Mallea, Jorge; Repetto, Paula; Orellana Vidal, Gricel; Betancourt, Ronald (Universidad de Almeria, 2018)
      We evaluated whether an extinction cue can reduce (or prevent) the recovery of previously extinguished fear conditioning using an ABC renewal design in humans. Two experiments were carried out. In Experiment 1, two groups ...
    • Miller, Ralph R.; Laborda Rojas, Mario; Polack, Cody W. (Elsevier, 2020)
      Renewal is the recovery of extinguished responding to a conditioned stimulus when testing occurs outside the extinction context. Renewal has been explained as the extinction context becoming a negative occasion setter ...
    • Laborda Rojas, Mario (Universidad de Chile, 2009)
      La noción darwiniana de continuidad de las especies ha justificado la investigación con animales no-humanos para entender al hombre. Si el hombre está evolutivamente conectado con el resto de los animales, entonces podemos ...
    • Betancourt Mainhard, Sigmond; Inostroza Parodi, Marión; Laborda Rojas, Mario (FOUNDATION ADVANCEMENT PSYCHOLOGY, 2008)
      There is evidence that drug-paired cues not only become associated with the drug effects but also become occasion setters that modulate the association of other cues with the drug effects, contributing to the development ...
    • Laborda Rojas, Mario; Quezada Scholz, Vanetza (Editorial Universitaria, 2010)
    • Polack, Cody W.; Laborda Rojas, Mario; Miller, Ralph R. (Elsevier, 2013)
      tThis paper addresses sources contributing to the differences in the degree of recovery from extinctionobserved with different renewal paradigms. In two lick suppression experiments with rats, we assessedthe role of the ...
    • Laborda Rojas, Mario; Miller, Ralph R. (Behavior Therapy 44 (2013) 249–261, 2013)
      Fear conditioning and experimental extinction have been presented as models of anxiety disorders and exposure therapy, respectively. Moreover, the return of fear serves as a model of relapse after exposure therapy. Here ...
    • González, Valeria V.; Navarro, Victor; Míguez Cavieres, Gonzalo; Betancourt, Ronald; Laborda Rojas, Mario (ELSEVIER SCIENCE BV., 2016)
      There is substantial evidence that drug-paired cues become associated with drug effects. From a Pavlovian perspective, these cues act as conditioned stimuli and elicit conditioned compensatory responses that contribute to ...
