چکیده

We investigated 4th-grade children's search strategies on sequential search tasks in which the goal is to identify an unknown target object by asking yes-no questions about its features. We used exhaustive search to identify the most efficient question strategies and evaluated the usefulness of children's questions accordingly. Results show that children have good intuitions regarding questions' usefulness and search adaptively, relative to the statistical structure of the task environment. Search was especially efficient in a task environment that was representative of real-world experiences. This suggests that children may use their knowledge of real-world environmental statistics to guide their search behavior. We also compared different related search tasks. We found positive transfer effects from first doing a number search task on a later person search task.

Car Use Behavioral Study for Commuting Trips: Parents’ Work Trips and Children’s School Trips

Negative consequences of car use along with deficiencies for investment in environmental friendly modes, have driven authorities to search for soft measure in order to encourage people for modal shift. The main objective of this study is to propose a model which describes car use behavior on parents’ work trips and how this relates to mode choice regarding their children’s school trips. A quest...

Iterative detection of MIMO transmission using a list-sequential (LISS) detector

For iterative detection in systems employing multiple antennas with an outer code we need a MIMO detector delivering a-posteriori probabilities (APP) about the coded bits. Full-APP detection would lead to prohibitive complexity, therefore we extend for high-level signals the concept of the sphere decoder using an approach from sequential decoding instead of geometrical considerations. We show h...

Children’s Subjective Well-being; Review on Definitions and Measures

Expended Abstract Introduction: Over the past decades there has been an increasing trend in research towards the children’s subjective well-being (SWB) as an important health and social policy issue. There are many scales for measuring SWB to the extent that selecting an appropriate scale among the available measures could still be regarded as a challenge. Given that measuring subjective well-...
