Twelve female normal listeners, all right-handed, heard rhyming pairs of (stop+/a/) nonsense syllables dichotically and monotically. Word onsets were simultaneous, then shifted by 15, 30, 60, and 90 msec. Each subject heard 600 pairs. Monotically, the lag-syllable discriminations were poor at all delays with differences leveling off at 30 msec (93% lead vs 19% lag). Dichotically, lag-ear discrimination was roughly 22% better for all lag times when the right ear lagged. [First found by Shankweiler and Studdert-Kennedy, personal communication.] Left-ear lag scores improved and overcame the right-ear advantage only after 30-msec delay. Total right-ear scores for entire dichotic portion of experiment (M=77%) exceeded total left-ear scores (M=66%) thus maintaining an over-all right-ear laterality effect. Thus, previous experimenters who allowed as much as 90-msec delay to be randomly distributed among their so-called “simultaneous pairs” might still have expected to find a right-ear laterality effect.

Computer mediated communication (CMC), especially via Web 2.0 technologies like social networking and casting software, has become an essential part of the lives of the current generation of college students. This chapter will explore the possibilities for the use of these technologies by universities and colleges to connect with their students and to enhance instruction. Topics covered will include Facebook, Twitter, virtual worlds, casting software, and future trends.
This chapter delves into the transformation of academic libraries in response to two main elements: Information Commons and Web 2.0 technologies, such as blogs and wikis. This transformation carries immense pedagogical significance for academic libraries by asserting a stronger presence of information literacy within the university curriculum. Traditional concepts of space, both virtual and physical, are also challenged by the inclusion of Information Commons and Web 2.0 technologies within academic libraries. Ultimately, what is revolutionized by these additions is the understanding of communication and pedagogy on the university campus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
