This study investigated the impact of power-of-speech style, need for cognition, and argument quality on participants' perceptions of a speaker, cognitive responses, and attitude toward the topic. Based on the Elaboration Likelihood Model (ELM) of persuasion, it was hypothesized that the three independent variables would interact to affect cognitive responses and attitude toward the topic. The results did not support the hypothesis. Path analysis was also used to analyze the data. The path analysis revealed that power-ofspeech style had a small, direct effect on attitude and several, indirect effects mediated by cognitive response categories. Argument quality had a direct effect on attitude toward topic. The results are discussed in terms of their importance for the persuasive effects of power-of-speech style, with specific focus on the role of speech style in an ELM framework.For a number of years, scholars have investigated the consequences of powerful and powerless speech styles for the evaluations of speakers. Generally, this research has found that across a number of situations, a powerful speech style produces positive speaker attributions and evaluations whereas a powerless speech style results in negative speaker attributions and evaluations (e.g., Adkins & Brashers, 1995;

Cat’s claw (Uncaria tomentosa (Willd. ex Schults) DC.), a plant that is exceptionally rich in phytochemicals, has been used for centuries by the indigenous people of South and Central America as a therapeutic and is currently widely exported for medicinal purposes. Extracts and individual components have shown considerable potential as antibacterials in the literature. The purpose of this review is twofold: first, to provide a substantiated, comprehensive collection of the known chemical constituents of U. tomentosa, including their detailed structures; second, to identify those components that offer some promise as antibacterials based on the research to date. Bacterial resistance to currently available antibiotics continues to increase and is widely recognized as an impending, potentially catastrophic, problem. There is research to suggest that U. tomentosa components may have antibacterial potential individually or synergistically with established antibiotics against microbes, including Borrelia burgdorferi, the causative agent of Lyme disease. It is our intention that this review will provide a valuable resource to investigators in search of new antimicrobials to meet the daunting challenge of antibiotic resistance.
