Instrumental conditioning involves two different processes: Goal-directed behavior, characterized by its dependence on the causal relationship between action and outcome and the sensitivity of actions to changes in the value of the outcome; and habits, characterized for its persistence and insensitivity to changes after conditioning. It is known th...

Este libro se enmarca en la colección Investigación e intervención en Psicología e incluye ocho capítulos escritos por jóvenes investigadores que trabajan o han trabajado en el Laboratorio de Conducta Animal y Neurociencia de la Facultad de Psicología de la Universidad de Sevilla. En estos capítulos se conjuga la tradición de investigación que se h...

A fundamental assumption of learning theories is that the credit assigned to predictive cues is not simply determined by their probability of reinforcement, but by their ability to compete with other cues present during learning. This assumption has guided behavioral and neural science research for decades, and tremendous empirical and theoretical...

Surprising violations of outcome expectancies have long been known to enhance the associability of Pavlovian cues; that is, the rate at which the cue enters into further associations. The adaptive value of such enhancements resides in promoting new learning in the face of uncertainty. However, it is unclear whether associability enhancements reflec...

Latent inhibition (LI) is a learning process observed when the acquisition of a CR (or CS-US association) to a stimulus paired with a reinforcer is retarded if the same stimulus has previously been pre-exposed in the absence of the reinforcer. Recent studies suggest that both the striatal dopaminergic innervation, and the dopaminergic activity of t...

El uso de animales de experimentación para el avance científico es una realidad irrevocable en nuestros días. La actividad investigadora implica una responsabilidad y una ética sustentada por una serie de normas y leyes. Esta normativa varía según el país donde se realice la actividad investigadora. En el presente capítulo nos centraremos en la...

El control motor se refiere al conjunto de procesos que propician la coordinación de un gran número de articulaciones y músculos al momento de realizar una acción. En cualquier acto motor, los mamíferos adoptan un patrón limitado de posturas y movimientos seleccionados por su grado de eficacia funcional. Así, en una acción multiarticular compleja e...

Motor control refers to the way in which the central nervous system manages the coordination of a large number of joints and muscles. In any motor act, mammals adopt a limited number of postures and movements selected due to their degree of functional efficiency. Thus, in a complex and intentional multi-joint action, such as grasping a standing obj...

Instrumental conditioning involved two different processes: 1) Goal-directed behavior, characterized by its dependence on the causal relationship between action and consequence and the sensitivity of action to change; and 2) learning of habits, that is relevant for its persistence and its insensitivity to post-learning changes. Currently we know th...

Previous studies in our lab have shown that latent inhibition (LI) could be understood as the extension of two processes controlled by dorsal and ventral striatum. Thus, we could attribute two clearly differentiated phases in the expression of LI. Diaz et al (2014) analyzed the LI and dorsal striatum activity establishing two types of CS exposition...
