An Investigation of Learning in a T-Maze with Relevant Drives Satisfied

Psychologists agree, in general, that the role of motivation in determining the behavior of organisms is an important one. However, different interpretations arise when one attempts to specify precisely what this role may be. Some psychologists believe that motivation serves only as a forcer or activator of behavior. Others hold that in addition to being an activator of behavior motivation must be reduced for learning to occur. Thus, field theorists such as Tolman and Leeper state that the acquisition of learning is not a function of the number of reinforcements, or drive state reductions. Rather, acquisition is dependent upon the temporal contiguity of the organism\u27s perceptions of successive stimuli, or signs and their significates. Once acquired, however, utilization of learning in the performance of a task is activated by an organism\u27s drive state

Spinneret: Aiding Creative Ideation through Non-Obvious Concept Associations

Mind mapping is a popular way to explore a design space in creative thinking exercises, allowing users to form associations between concepts. Yet, most existing digital tools for mind mapping focus on authoring and organization, with little support for addressing the challenges of mind mapping such as stagnation and design fixation. We present Spinneret, a functional approach to aid mind mapping by providing suggestions based on a knowledge graph. Spinneret uses biased random walks to explore the knowledge graph in the neighborhood of an existing concept node in the mind map, and provides "suggestions" for the user to add to the mind map. A comparative study with a baseline mind-mapping tool reveals that participants created more diverse and distinct concepts with Spinneret, and reported that the suggestions inspired them to think of ideas they would otherwise not have explored.Comment: ACM CHI 202
