The evolution of a goal-directed exploration model: effects of information scent and GoBack utility on successful
1Human-Computer Interaction Institute, Carnegie Mellon University.
Abstract:
We explore the match of a computational information foraging model to participant data on multi-page web search tasks and find its correlation on several important metrics to be too low to be used with confidence in the evaluation of user-interface designs. We examine the points of mismatch to inspire changes to the model in how it calculates information scent scores and how it assesses the utility of backing up from a lower-level page to a higher-level page. The outcome is a new model that qualitatively matches participant behavior better than the original model, has utility equations more appealing to "common sense" than the original equations, and significantly improves the correlation between model and participant data on our metrics.

01:14Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
