Gender differences in reward sensitivity and information processing were examined in two studies using a dynamic decision-making task. In Experiment 1, the optimal strategy involved forgoing an option that provided larger immediate rewards in favor of one yielding larger delayed rewards. In Experiment 2, the optimal strategy was to select the option that provided larger immediate rewards becaus...

Impulsivity is characterized in part by heightened sensitivity to immediate relative to future rewards. Although previous research has suggested that "high discounters" in intertemporal choice tasks tend to prefer immediate over future rewards because they devalue the latter, it remains possible that they instead overvalue immediate rewards. To investigate this question, we recorded the reward ...

It was hypothesized that emotional and unemotional individuals differ with respect to the utilization of internal sensations as cues. In comparison to unemotional Ss, emotional ones were expected to make more use of information concerning their internal reactions. Ss who were psychometrically classified as emotional or unemotional were shown 10 slides of seminude females while hearing a tape re...

This poster presents a model for motivated agents with behaviours influenced by an internal, domain independent motivation process rather than domain specific rewards, goals, or examples provided by an external teacher. Internal motivation is desirable in complex, dynamic environments where hard-coded domain theories can only approximate the true state of the world and where pre-programmed goal...

As presented in previous editions, our method describes the three-dimensional reconstruction of the internal and external surfaces of the human's left ventricle from medical data. The reconstruction is a first process inside a complete VR application that will serve as an important diagnosis tool for hospitals. The segmentation process has been thoroughly refined in order to provide a robust bo...

Using original survey data, this paper examines whether monetary rewards and honor rewards encourage or discourage blood donation. On the use of monetary rewards, we find that i) the overall sample’s response to monetary rewards is positive, and ii) people who volunteer more frequently, people who donated blood regularlt and people who donate blood to help others respond less positively to mone...

The state space of a sensor-based robot in the most previous works has been determined based on human intuitions, however the state space constructed from human viewpoints is not always appropriate for the robot. The robot has a di erent body, sensors, and tasks, therefore, we consider the robot should have an original internal state space determined based on actions, sensors, and tasks. This p...

The amygdala is a prime valuation structure yet its functions in advanced behaviors are poorly understood. We tested whether individual amygdala neurons encode a critical requirement for goal-directed behavior: the evaluation of progress during sequential choices. As monkeys progressed through choice sequences toward rewards, amygdala neurons showed phasic, gradually increasing responses over s...

We present an approach to solving the reinforcement learning problem in which agents are provided with internal drives against which they evaluate the value of the states according to a similarity function. We extend Q-learning by substituting internally driven values for ad hoc rewards. The resulting algorithm, Internally Driven Q-learning (IDQ-learning), is experimentally proved to convergenc...
