Performance--Psychological aspects.

The purpose of this research was to investigate if various psychological wellbeing
assessments can predict maximal strength performance and self-scored rating of
perceived exertion (RPE) in the back squat. Fifty-eight resistance-trained males and
females were recruited, and reported to the laboratory on one day. Subjects completed
eight different scales and questionnaires before completing one-repetition maximum
(1RM) testing of the squat, followed by two single-repetition sets at 30%, 40%, 50%,
60%, 70%, 80%, and 90% of 1RM, and a set to volitional fatigue at 70% of 1RM.
Cognitive anxiety and hypersomnia were found to be positive and negative predictors
(p<0.05), respectively, of 1RM performance. Further, self-confidence, grit, and perceived
recovery status were significant negative predictors of RPE (p<0.05). Finally, PRS was
discovered to be a positive predictor of subject-reported 1RM self-efficacy (b=0.39,
t=3.14, p<0.01, R2=0.15).

Psychologists have studied the relationship between personality and academic
performance for over a century, and more recently the relationship between personality
and situations, but no connection between academic performance and situation
characteristics has been researched. The current study examines this relationship using
the DIAMONDS dimensions and undergraduate GPA. Participants wore a life logging
camera to capture pictures of their surroundings for 24 hours and then self-sorted and
rated the photos into meaningful situations. Results found support for previous findings
of the relationships for personality with GPA and situations. Significant correlations
were found between GPA and Adversity, Deception, and Mating situations, though none
were significant unique predictors. There was also no correlation between GPA and
percentage of situations which took place in a classroom setting, though there was a significant correlation with time spent in a classroom. Limitations and future research
ideas are discussed.
