Performance of Brain-Injured versus Non-Brain-Injured Individuals on Three Versions of the Category Test

Description: To date, no research exists examining criterion-related validity of alternate, computerized forms of the Category Test. The intent of this study was to address criterion-related validity of three full forms of the Category Test. In that, the goal was to examine equivalency of each version in their ability to differentiate brain-injured from non-brain-injured individuals. Forty-nine (N = 49) healthy adults and 45 (N = 45) brain-injured adults were tested using three versions of the Category Test… more

Interactions of Presentation Formats and Decision-Maker Characteristics upon Multiple Decision-Making Tasks: an Experiment Using Multiple Cognitive Assessments

Description: Information systems research tends to ignore individual differences in users. This laboratory experiment sought to illuminate contributions of decision-makers' cognitive processes to decision outcome as reflected in four hypothesis sets: the impact of imagery preference and presentation format upon (HI) recall accuracy and upon hemispheric activation during (H2) encoding and (H3) recall, and (H4) to examine the relationship between hemispheric activation differences and accuracy differences.

Hemispheric Interactions and Event-Related Potentials in Lateralized Stroop and Stroop Analog Tasks

Description: Classical Stroop stimuli and newly developed face/word Stroop analog stimuli were used to investigate hemispheric interactions in Stroop interference effects (SEs) and corresponding event-related potentials (ERPs). Lateralized stimuli were presented unilaterally and bilaterally as congruent or incongruent color strip-word or face-word pairs (to invoke right hemisphere (RH) and left hemisphere (LH) specialization, respectively, in the latter case). The common finding for such tasks is that respo… more

Test-Retest Reliability on the Revised Conner's Parent Rating Scale

Description: The purpose of this study was to determine the test-retest reliability of the Revised Conners' Parent Rating Scale. The Conners' Parent Rating Scale (CPRS-48) was administered to 59 elementary school children between the ages of 5 and 10 years. After a period of two weeks, the same children were re-tested with the CPRS-48. The results of this research lend support to the integrity of the test-retest reliability of the CPRS-48. The need for further psychometric studies on the Conners' Scales is … more

Electroencephalographic Events During the Wisconsin Card Sorting Test

Description: Quantitative electroencephalography (QEEG) was used in this study to describe cognitive processing, particularly brain locations used, during performance of the Wisconsin Card Sorting Test (WCST). The hypothesis was that significant cognitive functioning is not limited to the frontal lobes. Significant EEG activity was found in non-frontal areas as well as frontal areas.

Neurophysiological and Behavioral Correlates of Language Processing and Hemispheric Specialization

Description: The purpose of this study was to examine language organization in the brain by using a series of three tasks concurrent with event-related potentials (ERPs) to investigate both hemispheric differences and interhemispheric reactions. Overall, the findings from this study support a relative rather than absolute hemispheric specialization for language processing. Despite an overall RVF (LH) advantage, both hemispheres were capable of performing the tasks and benefited from semantic priming.

Neuropsychological Functioning in Non-Schizophrenic First-Degree Relatives of Schizophrenics

Description: Research has consistently shown schizophrenics to perform significantly poorer than normal controls on commonly used measures of neuropsychological functioning. Research on the neuropsychological functioning of first-degree relatives of schizophrenics who do not themselves have schizophrenia is comparatively sparse but suggests the likelihood of deficits in this group as well. A battery of standard neuropsychological tests was administered to three groups: first-degree relatives of schizophreni… more

The Effects of Music Training on Electroencephalographic Coherence of Preschool Children

Description: The purpose of this study was to examine the effects of music training on electroencephalographic (EEG) coherence of preschool children. EEG coherence is a measurement of brain wave activity that reflects anatomical and neurophysiological parameters and functional connectivity between areas of the brain. Participants were 4- to 6-year-old children divided into two groups: one received music training for 20 minutes twice a week for 10 weeks while the other group served as controls. Nineteen chan… more

Behavior Patterns among Children with a History of Metopic Synostosis

Description: Metopic synostosis is a condition in which the metopic suture of the human cranium fuses prematurely and may be related to poor behavioral inhibition leading to behaviors commonly associated with Attention-Deficit Hyperactivity Disorder (ADHD). The purpose of this project was to examine the behavior patterns among children with a history of metopic synostosis. It was hypothesized that children with a history of metopic synostosis would exhibit many of the same behavioral patterns associated wit… more
