Predicting And Mitigating Reactance Impact On Attitude And Behavioral Intention, Matthew Ryan

UNLV Theses, Dissertations, Professional Papers, and Capstones

At times messaging may be of an instructive nature that can be perceived as an attempt to threaten or limit an individual’s freedom. This freedom limitation can range from individual choice to physical requirements. How a message is framed, or positioned, is very important. In certain instances, even when the message has the best intentions, if framed incorrectly can have the opposite, or boomerang, effect on people. This state is known as psychological reactance. When invoked, consumers will act in a way that eliminates the threat of freedom to restore balance. Such a state can also lead to negative implications …

Attentional Focus And The Development Of Skilled Performance, Harjiv Singh

UNLV Theses, Dissertations, Professional Papers, and Capstones

A central question in the development of skilled movement is: how a performer should focus their attention while preparing for the execution of a motor skill? Considerable evidence has shown that directing attention towards an intended movement effect (i.e., external focus) results in performance benefits relative to focusing on body movements (i.e., internal focus). While most of the previous research has emphasized the effects of internal versus external foci, evidence also suggests that external foci located at greater distances from the body (distal foci) are more effective than external foci located in greater proximity to the body (proximal foci) and …
