The influence of trait anxiety on information processing: An elaboration likelihood study
Title
The influence of trait anxiety on information processing: An elaboration likelihood study.
Creator
Appelbaum, Michael, Miller, Ann, Weger, Harry, Rubenking, Bridget, University of Central Florida
Abstract / Description
This study explored the influence of trait anxiety on information processing in persuasive situations, and investigated cognitive load as a mediator of this relationship. The research presented was based off DeBono and McDermott's (1994) framework for exploring trait anxiety and persuasion. The theoretical lens used to explore information processing, the elaboration likelihood model (Petty (&) Cacioppo, 1986) posits that motivation and ability are necessary components to elaborate on a...
Show moreThis study explored the influence of trait anxiety on information processing in persuasive situations, and investigated cognitive load as a mediator of this relationship. The research presented was based off DeBono and McDermott's (1994) framework for exploring trait anxiety and persuasion. The theoretical lens used to explore information processing, the elaboration likelihood model (Petty (&) Cacioppo, 1986) posits that motivation and ability are necessary components to elaborate on a message. However, very little research has addressed ability variables like trait anxiety. I predicted that students high in trait anxiety would be persuaded by the attractiveness of the source (peripherally) whereas students low in trait anxiety would be persuaded by the strength of the arguments presented (centrally).Undergraduate students were asked to view a picture of a policy presenter and listen to a recording of the student's proposed policy statement. After listening to the recording participants wrote down their thoughts during the presentation and were tested on their ability to recall the arguments presented. They then completed a few scale items assessing their attitudes toward the policy as well as questions to maintain the cover story.Findings showed no difference in processing between low and high trait anxious individuals. However, there was a significant effect of anxiety on attitudes. Additionally, cognitive load was not found to be a mediator of the relationship between anxiety and attitudes.

Show moreComputer security and privacy are becoming extremely important nowadays. The task of protecting computer systems from malicious attacks and potential subsequent catastrophic losses is, however, challenged by the ever increasing complexity and size of modern hardware and software design. We propose several methods to improve computer security and privacy from architectural point of view. They provide strong protection as well as performance efficiency. In our first approach, we propose a new dynamic information flow method to protect systems from popular software attacks such as buffer overflow and format string attacks. In our second approach, we propose to deploy encryption schemes to protect the privacy of an emerging non-volatile main memory technology – phase change memory (PCM). The negative impact of the encryption schemes on PCM lifetime is evaluated and new methods including a new encryption counter scheme and an efficient error correct code (ECC) management are proposed to improve PCM lifetime. In our third approach, we deconstruct two previously proposed secure cache designs against software data-cache-based side channel attacks and demonstrate their weaknesses. We propose three hardware-software integrated approaches as secure protections against those data cache attacks. Also we propose to apply them to protect instruction caches from similar threats. Furthermore, we propose a simple change to the update policy of Branch Target Buffer (BTB) to defend against BTB attacks. Our experiments show that our proposed schemes are both security effective and performance efficient.
