Participants used three pencil lead diameters (.5 mm, .9 mm, and a standard No. 2 pencil) to fill in “bubbles” on response sheets in one experiment; a .7-mm pencil was substituted for the No. 2 pencil in Exp. 2. Participants using a .5-mm pencil completed response sheets more slowly than when using a 7-mm, .9-mm, or a No. 2 pencil.

Zebrafish also display complex social behaviors like shoaling and schooling, making them an attractive model for investigating normal social behavior as well as exploring impaired social function conditions such as autism spectrum disorders. Newly-formed and established shoals exhibit distinct behavior patterns and inter-member interactions that can convey the group’s social stability. We used a three-chamber open-swim preference test to determine whether individual zebrafish show a preference for an established shoal over a newly-formed shoal. Results indicated that both sexes maintained greater proximity to arena zones nearest to the established shoal stimulus. In addition, we report the novel application of Shannon entropy to discover sex differences in systematicity of responses...

That is why it is necessary for scientists and technologists in different disciplines to meet and work together, even those in branches of knowledge which seem to have least relation and connection with one another. Antoine Lavoisier, 1793 Once science was the nearly exclusive province of the lone researcher. Now scientists from disparate fields glean grains of knowledge that when combined may address important societal problems and complex scientific questions. Individuals still must master their respective fields, but their contributions within teams assembled to transcend disciplines increasingly add to the whole to make it greater than the sum of the parts. Worldwide, scientific research has taken a new approach to discover and apply knowledge from many seemingly unrelated disciplines to create completely new research and pr...

A submerged T-maze was used to present both stimuli to healthy male B. splendens(N = 16). The results indicated that subjects' start box and swimway latencies decreased significantly over the 30 trials.
