wealth of research regarding the associations between forgiveness and rumination as well as perfectionism and rumination, all three concepts of
self-forgiveness, rumination, and perfectionism have never been studied in conjunction before. Given past research, I hypothesize that rumination
mediates the relationship between perfectionism and self-forgiveness. More specifically, I predict that increased levels of perfectionism will be
associated with increased levels of rumination, which, in turn, will result in decreased levels of self-forgiveness.

Previous research has shown that overconfidence, the belief that ability to perform a task is greater than actual ability, is associated with risky
behavior (Campbell, Goodie, & Foster, 2004). The present research evaluated the relationship between overconfidence, risky behavior, and narcissism
(confidence and feelings of self-sufficiency, often in the extreme). Male and female undergraduate participants were given a series of
questionnaires and participated in several tasks to assess overconfidence, narcissism, risky behavior and the need for achievement. Participants
were assigned to either an experimental condition, where participants bet on their ability to answer a series of general knowledge questions, or a
control condition, where participants rated their confidence in their ability to answer the same series of general knowledge questions. To examine
whether feedback had an effect on confidence, participants either received or did not receive feedback after answering each general knowledge
question. We hypothesized that those who merely rated their confidence would show less signs of overconfidence than those who bet on the accuracy
of their performance. Results have shown that the participants that were placed in the betting condition were notably more overconfident
than those who were only asked to rate their confidence. We also predicted that narcissism would correlate with risky behavior in participants.
Those who scored higher on a narcissism scale were also more likely to engage in risky behavior.

In the mirror illusion, visual information from a mirror reflection of one hand influences the perceived location of the other hand. Holmes, Crozier,
and Spence (2004) demonstrated this visual capture effect on a spatial localization task in which visual information was found to influence
reaching movements towards a target when the seen (in the mirror) and felt (proprioception) position of the hand did not match. In this present
experiment, the conflict between vision and proprioception was examined by means of a task in which participants adjusted the physical
distance between their two hands to match targets of different lengths. In each trial, participants viewed their visible hand and its reflection in
a mirror, while their unseen hand was positioned at one of four locations located behind the mirror. At all times, the visible hand was positioned
fourteen cm in front of the mirror, and as such, the unseen hand always appeared to be twenty-eight cm from the visible hand regardless of its
actual position. While viewing their visible hand and its reflection, participants performed simultaneous finger movements with both hands to
maximize the illusion. Participants then viewed a target block and repositioned their unseen hand such that the distance between their hands
matched the block length. Results suggest that movement of the unseen hand relative to the visible hand was biased by visual information from
the mirror, and this bias increased as the visual-proprioceptive conflict increased. These results suggest that the visual information about hand
position overrode the proprioceptive information when the hands were used to indicate perceived object length. Additional experiments will use
affordance judgments to further investigate how visual and proprioceptive information affect judgments of limb location and action capabilities.
