Acculturation Level, Generational Status and Gender: Their Role in Acculturative Stress in Young Adolescent Mexican Americans

Acculturation Level, Generational Status and Gender: Their Role in Acculturative Stress in Young Adolescent Mexican Americans

Date: August 2004
Creator: Manning, Suzanne C.
Description: The purpose of this study was to determine relationships between acculturation level, generational status, and gender with acculturative stress. Acculturation level was determined by the Acculturation Rating Scale for Mexican Americans-II (ARSMA-II) and acculturative stress was determined by the Societal, Attitudinal, Familial and Environmental Acculturative Stress Scale-Children's Version (SAFE-C). Subjects included 1268 Hispanic children ages 11-15. In order to validate the usefulness of the ARSMA-II with this sample, analyses were conducted between acculturation level and generational status. The Pearson product moment correlation (r=.44) and the ANOVA between the mean acculturation score and generational status were significant. However, the mean acculturation score from this study was considerably lower than the ARSMA-II score; therefore, new acculturation levels were developed to establish local adolescent norms for the ARSMA-II. All analyses involving acculturation levels were conducted using both the ARSMA-II and new acculturation levels because 300 subjects were reclassified with the new norms. Significant results were similar using both acculturation levels; however, there were more between group differences using the new acculturation levels. It was hypothesized that as acculturation level increased toward the Anglo culture, acculturative stress would decrease. The one-way ANOVA confirmed this relationship. It was also hypothesized that as generational status increased, ...

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY

Date: August 2001
Creator: Pottinger, Lindy Sylvan
Description: The purpose of this study was to examine the ability of the Cognitive Assessment System (CAS) and the NEPSY, A Developmental Neuropsychological Assessment, to differentiate between the subtypes of Attention Deficit/ Hyperactivity Disorder (AD/HD). The CAS and NEPSY are neuropsychological instruments which provide norms for AD/HD children in general. This study examined the performance of the two subtypes of AD/HD on the CAS and NEPSY. In addition, this study examined the performance of the two AD/HD groups on the Screening Test for Auditory Processing Disorders (SCAN). Since AD/HD children tend to have difficulty with language, the SCAN was used to determine if any of the AD/HD subjects had auditory processing difficulties that might impact their performance on the CAS and/or NEPSY subtests. The sample consisted of 118 children between the ages of 8 and 12 years of age. Using the DSM-IV criteria, the children were diagnosed as having three types of AD/HD: A Predominantly Hyperactive-Impulsive Type (AD/HD-HI), a Predominantly Inattentive Type (AD/HD-I) and a Combined Type The subtypes were also identified by the Attention Deficit Disorders Evaluation Scale-Home Version (ADDES-H). Only two subtypes, AD/HD-I and AD/HD-C, were identified by the ADDES-H. There were not enough AD/HD-HI subjects to include in ...

The Cross-Validation of AD/HD Instruments and the Relationship to Neurocognitive and Behavioral Measures

The Cross-Validation of AD/HD Instruments and the Relationship to Neurocognitive and Behavioral Measures

Access: Use of this item is restricted to the UNT Community.
Date: August 2002
Creator: Hudson, Christine V.
Description: The purpose of this study was twofold: to determine the construct validities of comparable AD/HD instruments that were developed according to our current, DSM-IV classification system for AD/HD; and to identify potential +neurocognitive and socioemotional markers for AD/HD. The sample consisted of 145 children ages 8 to 11 years of age who were diagnosed with Attention Deficit Hyperactivity Disorder (AD/HD), or Central Auditory Processing Disorder (CAPD). Children were administered a battery of neurocognitive tests and completed a self-report measure of personality. Parents completed several, AD/HD instruments pertaining to their children. The AD/HD instruments used in this study were the Attention Deficit Disorder Evaluation Scale-Home Version (ADDES), Attention Deficit Hyperactivity Disorder Test (ADHDT), and the Attention Problems and Hyperactivity scales from the BASC-Monitor (BASC-M). Of interest was how each AD/HD instrument compared to the DSM-IV, particularly in terms of the cross-consistency of AD/HD subtype classifications. The findings showed that the AD/HD instruments classified participants differently from the initial, DSM-IV entry diagnosis. Rates of agreement were better for some of the AD/HD instruments than for others yet there was little overall consistency. The neurocognitive measures used in the study were the Cognitive Assessment System-Basic Battery scales. The socioemotional measures used in the ...

Changes in Quantitative EEG and Low Resolution Tomography Following Cranial Electrotherapy Stimulation.

Changes in Quantitative EEG and Low Resolution Tomography Following Cranial Electrotherapy Stimulation.

Date: August 2006
Creator: Kennerly, Richard C.
Description: The effects of cranial electrotherapy stimulation (CES) on human EEG and brain current density were evaluated by quantitative electroencephalography (qEEG) and low resolution brain electromagnetic tomography (LORETA). A total of 72 research subjects were provided with a single session of CES, 38 were provided with 0.5 Hz CES while 34 were provided with 100 Hz CES. The qEEG paired t-tests revealed that in both frequencies of CES there was a significant (.05) increase in alpha relative power with concomitant decreases in delta and beta relative power. The 0.5 Hz CES decreased a wider frequency range of delta activity, while the 100 Hz CES decreased a wider frequency range of beta activity; suggesting some difference may exist in the EEG response to different frequencies of CES. The changes found in qEEG relative power were consistent with the affective and cognitive effects of CES reported in the literature, such as increased relaxation and decreased anxiety. Statistically significant changes for qEEG values other than relative power, such as coherence, amplitude asymmetry, phase lag and power ratios were also found. The LORETA paired t-tests found statistically significant (.05) increases in cortical and subcortical theta and alpha frequency current density with concomitant decreases in delta ...

Concurrent Validity of the Wide Range Assessment of Memory and Learning and the Woodcock-Johnson Tests of Cognitive Ability-Revised with a Neurologically Compromised Pediatric Population

Concurrent Validity of the Wide Range Assessment of Memory and Learning and the Woodcock-Johnson Tests of Cognitive Ability-Revised with a Neurologically Compromised Pediatric Population

Date: December 2000
Creator: Rochelle, Gary B.
Description: The Wide Range Assessment of Memory and Learning (WRAML) is a relatively new instrument used in the assessment of memory in children. The purpose of this study was to examine the validity of the WRAML by comparing the performance of children on both the WRAML and the Woodcock-Johnson Tests of Cognitive Ability- Revised (WJTCA-R). Subjects for the study were children in treatment for a brain tumor at a regional children's medical center. Fifty children participated in the study ranging from ages 6 to 17. A multiple regression analysis was conducted to determine which of four selected clusters from the WJTCA-R would have the highest correlation with the Verbal Memory Index (VERI) from the WRAML. The Short-Term Memory (GSM) cluster had the highest correlation ( r = .82) as predicted. A Pearson's product-moment correlational analysis was conducted between the Visual Processing (GV) cluster from the WJTCA-R and the Visual Memory Index (VISI) from the WRAML. GV was found to have a high positive correlation ( r = .63) with VISI. A similar analysis was conducted between the Long-Term Retrieval (GLR) cluster from the WJTCA-R and the Learning Index (LRNI) from the WRAML. GLR was found to have a high positive correlation ...

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

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

Date: August 1998
Creator: Suire, David M. (David Mark)
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 schizophrenics who do not themselves have schizophrenia (FDR-SCZ), first-degree relatives of persons with major depression and bipolar disorder (FDR-MOOD), and normal controls (NC). The FDRSCZ group was not found to demonstrate significantly impaired performance relative to the other two groups on any of the hypothesized or exploratory analyses. These implications of these findings are discussed with reference to previous studies and future research.

Development and Validation of the Checklist for Differential Diagnosis of Attentional Problems

Development and Validation of the Checklist for Differential Diagnosis of Attentional Problems

Date: May 1999
Creator: Taylor, Cindy J.
Description: The current study discussed the development and validation of the Checklist for Differential Diagnosis of Attentional Problems (CDDAP), a tool for use with adults seeking diagnosis and treatment of an Attention Deficit Hyperactivity Disorder. Normative data are provided on three subject groups (ADHD adults, controls, and adults with other psychiatric disorders). Convergent validity was established with the SCL-90, and criterion validity established through comparing scaled scores with final diagnoses. Overall, this measure was accurate at differentiating adults with ADHD from controls and adults with other psychiatric disorders. Results indicated that the CDDAP was also able to identify other psychiatric disorders with 71 to 92% accuracy, depending on the disorder.

Validation of the Expanded McCarron-Dial System for Diagnosis of Neuropsychological Dysfunction in Adults

Validation of the Expanded McCarron-Dial System for Diagnosis of Neuropsychological Dysfunction in Adults

Date: August 1998
Creator: Colaluca, Beth
Description: The McCarron-Dial System (MDS) has successfully predicted vocational and independent living outcomes with neuropsychologically disabled individuals receiving rehabilitation services. In addition, preliminary validation studies suggest that the abbreviated MDS is useful for clinical neuropsychological diagnosis. The present study represents part of an ongoing research project aimed at validating the expanded version of the MDS for diagnosis of neuropsychological dysfunction. Specifically, it was hypothesized that the expanded MDS would be able to accurately discriminate between brain-damaged and non-brain-damaged individuals. Accurate diagnosis facilitates rehabilitation efforts for individuals with neuropsychological disabilities and the data profile provided by the expanded version of the MDS can consequently form the basis from which more complete individual treatment and rehabilitation plans can be conceptualized.

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Couvadelli, Barbara
Description: The purpose of this study was to determine if attention-deficit/hyperactivity disorder (ADHD) subtypes (predominantly hyperactive/impulsive, ADHD-HI; predominantly inattentive, ADHD-IA; combined, ADHD-C) exhibit distinct neuropsychological profiles, using the Attention and Executive Function subtests of the Developmental Neuropsychological Assessment, (NEPSY) and the omission and commission scores obtained on the Conners' Continuous Performance Test-II (CPT-II), a test that assesses attention processes. The sample was selected using archival data collected in a neurodevelopmental clinic over the past decade and consisted of 138 children between the ages of 6 and 12 years old. Using the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) criteria, the children were placed in either the ADHD-HI (n = 40), ADHD-IA (n = 35), or ADHD-C (n = 36) group, or a symptom free comparison group (n = 27). It was hypothesized that children with elevations on the impulsivity/ hyperactivity (ADHD-HI and ADHD-C) scale would be impaired on measures of inhibition and those with elevations on the inattention scale (ADHD-IA and ADHD-C) would be impaired on tests of attention, vigilance, and other executive functions. A one-way multivariate analyses of variance (MANOVA) was conducted (Group X Task), with significant results for overall main effect for group on the 7 ...

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

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

Date: December 1994
Creator: Henson, Kerry L. (Kerry Lynn)
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. Point-value (specific values) and intraset-pattern (relationships between values) recall were considered. Thirty MBA students, grouped by imagery preference (cognitive style) as favoring verbal (textual) or visual (graphical) information presentation, performed computer-based recall tasks using tabular and graphical formats in a repeated measures design. Hemispheric activation (cognitive process) was assessed using ratios of EEG activity in six frequency bands captured from six pairs of homologous electrode sites during encoding and recall.

Behavior Patterns among Children with a History of Metopic Synostosis

Behavior Patterns among Children with a History of Metopic Synostosis

Date: August 2000
Creator: Kuper, Bradley D.
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 with ADHD. It was also hypothesized that children with a history of simple synostosis not involving the metopic suture would not evidence this type of behavioral pattern. In order to test these hypotheses, the behavior of three groups of children was compared including (1) children who had a history of metopic synostosis (M= 7.63 years, SD = 1.92 years), (2) children who had a history of simple craniosynostosis not involving the metopic suture (M= 7.54 years, SD = 1.88 years), and (3) a group of children diagnosed with ADHD (M=7.78 year, SD = 1.87 years). It was found using the Home and School versions of the Attention Deficit Disorders Evaluation Scale (ADDES) that children with a history of metopic synostosis demonstrate significantly more behavioral disturbances than children ...

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

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

Date: December 1997
Creator: Kavcic, Voyko
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 responses for the congruent condition are faster and more accurate than for the incongruent condition (i.e., the SE). A primary prediction is that the SE will be maximized when both the distractor and target components, or distractor alone, are presented to the specialized hemisphere (i.e., LH for words and RH for faces). A total of 88 right-handed University of North Texas students participated in one of four experiments. Participants manually responded to one component of the stimuli (i.e., color, face, or word), while ignoring the other. Behaviorally, participants showed a robust SE across all experiments, especially for the face/word task with word targets. Findings from the face/word Stroop analog tasks also indicated that SEs were produced by selective attention to either faces or words, implicating a role for top-down (controlled) processes. Hemispheric asymmetries were observed ...

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

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

Date: August 1994
Creator: Mercer, Walt N. (Walt Neilson)
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, the BDI, and the WAIS-R NI. ANOVA indicated no significant differences between versions of the Category Test or an interaction between Category Test version and group membership on the total error score. MANOVA performed between versions of the Category Test and Subtest error scores indicated significant differences between versions on Subtest 3 and Subtest 6. Group membership (brain-injured v. non-brain-injured) produced a significant main effect on all subtests of the Category Test except Subtest 2. Several exploratory analyses were performed examining the relationship between neuropsychological impairment, group membership based on Category Test error scores, and the WAIS-R NI. Clinical applications, such as the use of serial testing to index neurorehabilitation gains, were discussed.

The Effects of Music Training on Electroencephalographic Coherence of Preschool Children

The Effects of Music Training on Electroencephalographic Coherence of Preschool Children

Date: August 1999
Creator: DeBeus, Roger J. (Roger John)
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 channels of EEG data were collected from each child pre- and post-training. Data were collected from three conditions: eyes-open resting, listening to music, and performing the Object Assembly subtest of the Weschler Preschool and Primary Scale of Intelligence - Revised (1989). The hypothesis was that the music training group would show increased EEG coherence as compared to controls. The EEG data was reduced into seven bandwidths and analyzed separately for each condition. Multiple ANCOVAs were used to factor out pre-test variability and to maximize connectivity changes between the two groups. The dependent measures were the post-QEEG electrode pairs and the covariates were the pre-QEEG electrode pairs. Results indicated the eyes-open and listening to music conditions showed more significant changes between the groups than the Object Assembly ...
