“…In fact, Marlin and Miller (1981, Exp. 4; see also Baker & Mercier, 1982;Hall & Minor, 1984) saw increases in habituation after extinction of the context where habituation had previously been administered. However, Jordan, Strasser, and McHale (2000) found the opposite effect using lick suppression, which is the same dependent measure used here, so we could not categorically reject the possibility that habituation to the CS was responsible for the PPD we observed in Experiment 1. In addition, the results of Experiment 1 (and the recovery observed in Exp.…”

“…Habituation in laboratory rodents is context specific, so "recovery" of the response occurs in contexts different from that where the habituation occurred (Jordan and Strasser, 2000). Should elements of the context alter, a startle response may recur, particularly if the change of context is salient to the animal.…”

Minimizing fear and anxiety in working dogs: A review

The causes of fear and anxiety in working dogs are multifactorial and may include inherited characteristics that differ between individuals (e.g. Goddard and Beilharz, 1982; 1984a,b), influences of the environment (Lefebvre et al., 2007), and learned experiences during particular sensitive periods (Appleby et al., 2002) and throughout life. Fear-related behavior compromises performance, leads to significant numbers of dogs failing to complete training (e.g., Murphy, 1995;Batt et al., 2008), early withdrawals from working roles (Caron-Lormier et al., 2016), and can jeopardize dog and handler safety. Hence, amelioration of fear and anxiety is critical to maintain dogs in working roles and to ensure their well-being. Although current methods of selection and training are seemingly effective at producing many dogs which work in a remarkable array of environments, some dogs do not make the grade, and longevity of service is not always maximized. Programs should strive for optimal efficiency and they need to continually analyze the value of each component of their program, seek evidence for its value and explore potential evidence-based improvements. Here we discuss scientific evidence for methods and strategies which may be of value in reducing the risk of fear behaviors developing in the working dog population and suggest potentially valuable techniques and future research to explore the benefit of these approaches. The importance of environmental influences, learning opportunities, and effects of underlying temperament on the outward expression of fear and anxiety should not be underestimated. Identification of characteristics which predict resilience to stress are valuable, both to enable careful breeding for these traits and to develop predictive tests for puppies and procured animals. It is vitally important to rear animals in optimal environments and introduce them to a range of stimuli in a positive, controlled, and gradual way, as these can all help minimize the number of dogs which develop workinhibiting fears. Future research should explore innovative methods to best measure the relative resilience of dogs to stressful events. This could include developing optimal exposure protocols to minimize the development of fear and anxiety, and exploring the influence of social learning and the most effective elements of stimulus presentation.

“…El procedimiento seguido por Jordan et al (2000) y por la presente investigación, en el cual se examina simultáneamente el curso de la habituación de más de una respuesta, permite descartar explicaciones alternativas con las cuales se podrían cuestionar los resultados de otros estudios, donde se examina un solo sistema de respuesta en forma aislada. Por ejemplo, en aquellos estudios donde se demuestra ausencia de control contextual de una respuesta (p.…”

“…El hecho de que Jordan et al (2000) hayan demostrado simultáneamente ausencia y presencia de control contextual de distintas respuestas ante el mismo estímulo, sugiere que podrían existir dis- tintos mecanismos de habituación para distintos sistemas de respuesta. Estudios previos realizados con un solo sistema de respuesta apuntaban en la misma dirección.…”

“…Por ejemplo, al menos 2 estudios han demostrado que la habituación de la respuesta de sobresalto se transfiere completamente de un contexto a otro (Borszcz, Cranney, & Leaton, 1989;Marlin & Miller, 1981). Por otra parte, el control contextual de la habituación de la respuesta de supresión fue confirmado por Jordan et al (2000) en experimentos independientes (Experimentos 3, 4 y 5), y otros estudios han encontrado evidencia de especificidad contextual con procedimientos tales como las respuestas de escape en cangrejos (Tomsic, Pedreira, Hermitte, Romano, & Maldonado, 1998), de movimiento en invertebrados (Rankin, 2000) y de orientación en ratas (Hall y Channel, 1985;Jordan et al, 2000 [Experimento 5]). La excepcionalidad de la repuesta de sobresalto en no mostrar control contextual de la habituación sugiere que en este caso podría operar un mecanismo de habituación diferente a aquel que opera en otras respuestas.…”

Especificidad contextual diferencial en la habituación de las respuestas de parpadeo y aceleración cardiaca en humanos

et al. 2014

r e S u m e n Wagner (1978) propuso que la habituación, definida como una disminución en la respuesta a un estímulo que se repite, dependería de la formación de una asociación entre el contexto y el estímulo. Según este enfoque, la habituación debería ser contexto-específica, es decir, la respuesta habituada en un contexto debería deshabituarse al presentar el estímulo en un contexto novedoso. Esta hipótesis fue examinada a través de un experimento donde se sometió a un grupo de estudiantes a una sesión de habituación consistente en 60 repeticiones de un estímulo provocador de reacciones de parpadeo y aceleración cardiaca. Posteriormente, en una sesión de prueba se midió la amplitud de estas respuestas, presentando el estímulo en el mismo contexto (Grupo Igual) o en un contexto distinto a aquel donde ocurrió la habituación (Grupo Diferente). Los resultados de la prueba arrojaron evidencia de especificidad contextual diferencial para ambas respuestas, ya que la respuesta de aceleración cardiaca resultó disminuida en el grupo igual pero no en el grupo diferente (revelando especificidad), mientras que la respuesta de parpadeo estuvo igualmente disminuida en ambos grupos (revelando ausencia de especificidad). Estos hallazgos confirman observaciones previas con ratas que demuestran que el control contextual de la habituación depende de la naturaleza de la respuesta. Wagner (1978) proposed that habituation, defined as a decrease in responding to a repeated stimulus, would depend on the formation of an association between the stimulus and the context. According to this approach, habituation should be context-specific; that is, a response that was habituated in a given context should dishabituate when the stimulus is presented in a novel context. This hypothesis was examined in an experiment in which a group of students received a habituation session consisting of 60 repetitions of a stimulus capable of evoking eyeblink and heart-rate acceleration reactions. Subsequently, in a testing session the amplitude of these responses was examined by presenting the stimulus in the same context used in the habituation session (Group Same) or in an alternative context (Group Different).
