An Evaluation of Several Measures of Attention and Inhibition in Ten Year Old ChildrenPasquali, Bernadette 19 March 2014 (has links)
Due to numerous definitions for attention and inhibition, it is very difficult to
operationalize and measure these constructs (Barkley, 1996). The primary purpose of
this study was to determine whether there is evidence for independence between attention
and inhibition constructs using measures from the TEA-ch, Gordon CPT, Stroop Task,
WISC- Digit Span and Go-No-Go Tasks and tasks of inhibition. Each of 140 students
were evaluated on all measures and scores were correlated. In addition, Teacher Ratings
and scores from the OLSAT were also correlated with attention and inhibition scores.
Gender differences between all scores were also examined.
Overall, measures did not correlate as expected. Results showed that there were
significant but weak correlations among the sustained and selective attention variables.
Similarly, when all inhibition variables were correlated only four significant but weak
correlations were found. The lack of convergent validity and low correlations among
these measures suggest that attention and inhibition constructs may be multi-dimensional.
Intercorrelations between attention and inhibition variables were also weak.
Relationships between OLSAT scores, Teachers Ratings and attention and
inhibition variables showed that as scores that reflect reasoning skills and Teacher
Ratings increased, the ability to attend and inhibit also increased. Gender differences in
attention and inhibition scores were also examined and showed that girls were better at
paying attention to stimuli and inhibiting impulsive responses than boys.

Perceptual Style, Field Dependence, and Accident InvolvementSmith, J. Murry 08 1900 (has links)
It was hypothesized that field dependence and attention measures would differentiate accident-loaded and accident-free employees of a petroleum services company.
Analysis of variance revealed main effects and a three-way interaction for the Rod-and-Frame Test. Main effects occurred for the Attention-Diagnostic Method and Embedded- Figures Test. No differences occurred for the Closure Test. Regression analysis produced an R (76) = .41, p < .01, with the Attention-Diagnostic Method contributing more to prediction. Equality-symmetry violations occurred in the data.
Cautious interpretation was advised because of the assumption violations. The accident-loaded subjects produced consistently greater performance variances, which suggested general performance characteristics in several respects.
Future research should be longitudinal-predictive, oriented from Kerr 's complementary safety theories.
