Examining Reliability And Validity Of The Roadsign Perception Test, Justin Hull Ory
Examining Reliability And Validity Of The Roadsign Perception Test, Justin Hull Ory
LSU Master's Theses
The Road Sign Perception Test (RSPT) is a newly developed assessment procedure related to driver advisement, and its psychometric properties have not yet been examined systematically. The present study examined the construct validity and the reliability of RSPT measurements. Cronbach’s α and test-retest reliability statistics were completed, as were correlations reflecting on the test’s construct validity. Results indicated that the RSPT possesses marginal test-retest reliability, adequate internal consistency for duration of stimulus presentation and for specific stimuli, but low for number of signs presented. RSPT performance was significantly correlated with convergent variables measuring aspects of attention, working memory, and spatial …
The Interactions Between Sentence Complexity, Working Memory, And Additional Working Memory Load: An On-Line Measure, Christy Seidel
The Interactions Between Sentence Complexity, Working Memory, And Additional Working Memory Load: An On-Line Measure, Christy Seidel
LSU Master's Theses
This experiment takes an on-line look at syntactical complexity, external loads, and working memory, and how the three influence one another. Based on off-line data looking at the interactions between these three factors, we have discovered that syntactic complexity and span have main effects, while the effect of load is most interestingly seen in a three way interaction representing the hardest possible combination of factors. Through this new design, we were able to see whether the off-line results of sentence processing are replicated with an on-line measure. Our new off-line findings replicate past results, which show that working memory impacts …
