Two experiments assessed the moderating impact of task context on the relationship between reward and cardiovascular response. Randomly assigned to the cells of a 2 (task context: reward vs. demand) x 2 (reward value: low vs. high) between-persons design, participants performed either a memory task with an unclear performance standard (Experiment 1) or a visual scanning task with an unfixed per...

This paper describes an application to form teams from a given set of employees. The teams are assigned to perform task. To accomplish a task a team has to fulfill specific requirements which have to been minded while assigning teams to task. The goal is the forming of a chain of task meeting specific requirements and assigning a team to each task able to solve it. These chains have to be optim...

Two experiments examined the effects of interactive tutorial features (compared to “passive” features) on learning spatial tasks, an area seldom explored in interactivity research. Experiment 1 results indicated that for simple spatial tasks, interactive tutorials hindered learning for participants of higher spatial ability but improved learning for lower-ability participants. This interaction ...

In this paper, the possibilities of using visual and textual information are investigated to improve the ranking of photos from Flickr about famous places. We have elaborated improved textual features based on standard ones and visual features e.g. face feature for measure the relative face area on the images. These heuristic features have been used for the solution in the MediaEval 2013 Retrie...

This experimental study examined the relationship between pretend play and false-belief. Eighteen-month-old children engaged in pretend play with an experimenter using various controlled behaviors and performed a false-belief task. The results showed that the children who understood pretend play performed better on the false-belief task. This suggests that pretended play and false-belief are re...
