Description
Language and music are fundamentally entwined within human culture. The two domains share similar properties including rhythm, acoustic complexity, and hierarchical structure. Although language and music have commonalities, abilities in these two domains have been found to dissociate after brain damage, leaving unanswered questions about their interconnectedness, including can one domain support the other when damage occurs? Evidence supporting this question exists for speech production. Musical pitch and rhythm are employed in Melodic Intonation Therapy to improve expressive language recovery, but little is known about the effects of music on the recovery of speech perception and receptive language. This research is one of the first to address the effects of music on speech perception. Two groups of participants, an older adult group (n=24; M = 71.63 yrs) and a younger adult group (n=50; M = 21.88 yrs) took part in the study. A native female speaker of Standard American English created four different types of stimuli including pseudoword sentences of normal speech, simultaneous music-speech, rhythmic speech, and music-primed speech. The stimuli were presented binaurally and participants were instructed to repeat what they heard following a 15 second time delay. Results were analyzed using standard parametric techniques. It was found that musical priming of speech, but not simultaneous synchronized music and speech, facilitated speech perception in both the younger adult and older adult groups. This effect may be driven by rhythmic information. The younger adults outperformed the older adults in all conditions. The speech perception task relied heavily on working memory, and there is a known working memory decline associated with aging. Thus, participants completed a working memory task to be used as a covariate in analyses of differences across stimulus types and age groups. Working memory ability was found to correlate with speech perception performance, but that the age-related performance differences are still significant once working memory differences are taken into account. These results provide new avenues for facilitating speech perception in stroke patients and sheds light upon the underlying mechanisms of Melodic Intonation Therapy for speech production.

Description
Research on teamwork has shown that teams are more productive and produce better results than individuals working on their own. Yet, research on individuals' work preferences makes it clear that not everyone prefers working in teams. In order to improve teamwork and achieve better results in both the collegiate arena and in the professional world, this study was designed to research different factors that affect a group's performance and creativity: satisfaction, familiarity, and the behavioral styles of individual team members. Additionally, this study addresses if the group's composition of Keirsey types \u2014 temperament patterns \u2014 also play a role in the group's creativity and performance. In this study, students created teams of four to seven students and completed specific in-class activities called Applied Insights. Groups composed mostly of Guardians, one of the four Keirsey temperaments, are able to adapt to the task at hand, which is demonstrated here with creativity. Further, groups who perceive themselves as sharing similar traits with many members are more satisfied and achieve a higher overall performance. Lastly, groups comprised of individuals who were least familiar with their teammates they had not previously worked with, produced more creative results in the short run. Whereas groups comprised of individuals who were least familiar with their teammates they had previously worked with, produced better overall results in short run.
