Hyperfocus in adult ADHD : an EEG study of the differences in cortical activity in resting and arousal states20 November 2013 (has links)
M.A. (Psychology) / Attention deficit/hyperactivity disorder (ADHD), characterised by problems relating to attention, impulsive behaviour and hyperactivity, has become widely accepted to be a neurodevelopmental disorder that persists into adulthood for a large proportion of the ADHD population. ADHD symptoms are reported to undergo developmental transformation from childhood to adulthood, resulting in a significantly different clinical picture of adult ADHD. This signals a need to move away from reliance on childhood models of the disorder. Current conceptions of both childhood and adult ADHD do not discuss the occurrence of hyperfocus (or flow), a symptom which seems to connote an extreme form of sustained attention and which has been noted in clinical work. The possibility that hyperfocus could occur in ADHD is unexpected and poses a challenge to current formulations of inattention in ADHD. Media settings have been identified as providing the conditions needed for one to enter the hyperfocus state. This study set out to explore the possible symptom of hyperfocus in ADHD and to attempt to identify the neural correlates thereof, using electroencephalograph (EEG). A sample of 10 participants (5 ADHD, 5 non-ADHD) was recruited using the Adult ADHD Self Report Scale V-1.1 (ASRS V-1.1) Screener and a biographical questionnaire. A quasi-experimental research design was employed, whereby EEG recordings of frontal, frontal midline and parietal regions were taken for each participant during resting states (Eyes Closed and Eyes Open) and whilst playing a first person shooter game. Post-test survey questionnaires were also administered to examine the participants’ time perception during game play. Between-group and within-group differences in absolute and relative power scores were examined, using non-parametric statistical methods (Mann-Whitney-U test and Wilcoxon Signed Rank Test) to analyse the data. Possible markers for hyperfocus were identified, namely significantly lower alpha and beta levels in the ADHD group, as well as a decrease in slow-wave activity over time, as well as post-test survey data that indicated a greater degree of distorted time perception in the ADHD group during game play. Significant between- and within-group differences found in the parietal region highlight the need for further research into the role of the parietal lobe in attention functions and in ADHD. Further, significant changes in cortical activity in the progression from Eyes Closed to Eyes Open in both groups warrant further investigation.

A comparative study of the vocational interests of adults with and without ADHD06 May 2015 (has links)
M.A. (Clinical Psychology) / Although Attention-Deficit/Hyperactivity Disorder (ADHD) was once thought to occur exclusively in the course of childhood, remitting in adolescence, it is increasingly accepted as a valid diagnosis in adulthood, with DSM-5 providing diagnostic criteria adapted for adults. Symptoms of ADHD in adulthood can lead to impairment in the occupational and tertiary educational environments among others, and additionally can lead to individual differences in ability to perform certain occupational functions, as well as in the occupations to which an individual may be attracted. Adults with ADHD have been shown to differ significantly in personality from non-ADHD adults. The "goodness of fit" between personality and environment underlies much of the predominant understanding of occupational choice. In addition to impairment in the work environment, a lack of fit may exist between adults with ADHD and many features common to organisations. Despite this, along with acknowledgement of the influence of career choice on various factors, including success, emotional welfare and personal productivity, there is a lack of literature dealing specifically with career counselling in ADHD populations. In order to investigate the differences between adults with and without ADHD in a number of areas commonly assessed for career counselling and guidance purposes, an ADHD screening tool, the Adult ADHD Self-Report Scale (ASRS) was administered to a sample (n=60) of adults with and without ADHD. Participants were then assigned to ADHD and non-ADHD groups on the basis of ASRS scores in conjunction with diagnostic history, and assessed by means of the Self-directed Search Questionnaire (SDS), and the Basic Traits Inventory (BTI). Tests for between-group differences revealed significant differences on a small number of variables with the ADHD group scoring significantly higher on only the Enterprising type of the SDS. On the BTI, the ADHD group scored significantly higher on Extraversion, and significantly lower on Conscientiousness. The ADHD group also scored significantly higher on the Actions, Ideas, and Imagination facets of the BTI's Openness to Experience factor.

Correlates, Antecedents, and Consequences of Reading Disabilities in 11-Year-Old Children with ADHD as a Major CorrelatePisecco, Stewart (Stewart Anthony) 08 1900 (has links)
The purpose of this study was to follow the development of children with reading disabilities only, reading disabilites and ADHD, ADHD only, and a comparison group from the ages of 3 to 18. Differences were examined on the following variables: (a) Antecedent variables- Reynell Developmental Language Scales, Temperament, and Family Adversity; (b) School-age variables- behavioral and academic self-concept ratings; and (c) Psychological adjustment variables at age 18- self-reports of delinquency. Children from the reading disabled groups exhibited receptive language deficits, were from families who during the early childhood years had less resources to cope with problem situations, exhibited difficult temperamental characteristics, and had negative academic self-concepts. Distinctions were also noted between a "pervasive" and "situational" presentation of behavioral problems. During late adolescence the reading disabled groups exhibited similar levels of delinquency as their non-disabled peers. The implications of this study and directions for future research are discussed.

Student Teachers' Explicit and Implicit Perceptions of Attention-Defici t/H yperacti vi ty DisorderBerglof, Hollie K. 01 May 2007 (has links)
This study examined student teachers' explicit and implicit perceptions of ADHD and the relationship between perceptions of ADHD and social desirability. In addition, the relationship between a current measure of implicit perceptions of ADHD and one that was adapted for this study was also investigated. Findings indicate that student teachers view a student portrayed as exhibiting symptoms consistent with ADHD more negatively than a "normal" child in terms of their self-reported first impressions of the child as well as their predictions for the child's future success. Participants' perceptions, as measured by two implicit measures, however, were mixed, with results from one measure indicative of neutral attitudes toward ADHD, while results from another measure were suggestive of an implicit attitude bias against ADHD behaviors. Overall, social desirability did not appear to be meaningfully associated with student teachers' implicit or explicit perceptions of ADHD. The key findings seem to indicate that student teachers generally exhibit more negative perceptions of stereotypical ADHD behaviors than "normal" behaviors. Two measures of student teachers' implicit perceptions of ADHD were not significantly related.

Factors that influence the prescribing and use of methylphenidate for attention-deficit/hyperactivity disorder in primary school children in PolokwaneCoetzee, Barbara Corné January 2009 (has links)
Theses (MSc.(Med.)(Pharmacy))--University of Limpopo, 2009. / Background: Attention-Deficit/Hyperactivity Disorder (ADHD) is the current diagnostic
label for children presenting with significant problems with attention, and typically with
impulsiveness and excessive activity as well. It is the most common neurobehavioural disorder
of childhood, and therefore critical to clarify the diagnosis. ADHD is a seemingly heterogeneous
group of behaviour disorders affecting between 5% - 10% of primary school children. Overdiagnosis
of ADHD and overprescribing of stimulants are considered problems in some
communities, emphasising the need for careful evaluation and diagnosis. Methylphenidate is
currently the first choice of treatment. The main focus of this study was to investigate whether
the diagnosis of these children was done by field experts according to the criteria as set in the
DSM-IV TR. This influences the decision to prescribe methylphenidate and the monitoring of the
child during treatment.
Method: The parents of 50 clinically diagnosed ADHD children, from various primary
schools situated in Polokwane, were interviewed and completed a questionnaire.
Results: The findings indicated that 20% of the sample did not meet the DSM-IV TR
criteria. 28% of the sample was advised to take methylphenidate by people without appropriate
clinical knowledge of ADHD. The final diagnosis and prescribing of methylphenidate is
overwhelmingly done by General Practitioners (47%). ADHD symptomatology (hyperactivity -
impulsiveness and inattention) was not taken in account when prescribing methylphenidate.
There was no definite monitoring of patients before and while on methylphenidate. Positive
improvements in ADHD symptoms after methylphenidate therapy, shows that methylphenidate
is still prominent and successful in the pharmacotherapy of the ADHD child.
Conclusion: Based on the results of the study there does not appear to be enough
evidence that proper protocols or guidelines were followed. Some children were diagnosed as
having ADHD with insufficient evaluation and in some cases stimulant medication was
prescribed when treatment alternatives might exist. It seems that not all clinicians prescribing
methylphenidate have the necessary professional experience and/or qualifications regarding
ADHD. This is an indication that there is a need for South African guidelines similar to The
American Academy of Pediatrics’ Clinical Practice Guidelines and the European Clinical
Guidelines for Hyperkinetic Disorder. However, with correct diagnosis and individualised
prescribing and usage of methylphenidate, there will be positive improvements in ADHD
symptoms after methylphenidate therapy.

Relationships between Life Satisfaction, Symptoms of Inattention and Hyperactivity/Impulsivity, and Depressive Symptoms in High School StudentsBateman, Lisa Paige 02 June 2014 (has links)
Given increased evidence related to the importance of fostering life satisfaction in the overall population (Diener & Diener, 1996), as well as recent suggestions regarding the importance of increasing positive academic and social outcomes for children with ADHD (DuPaul, 2007), it is important to gain a clearer understanding of how life satisfaction may be related to symptoms of inattention and hyperactivity/impulsivity. Research on the relationship between life satisfaction and symptoms of inattention, hyperactivity, and impulsivity is currently limited to two studies (Gudjonsson et al., 2009; Ogg et al., 2014). The current study investigated the relationship between symptoms of inattention and hyperactivity/impulsivity and reports of global life satisfaction in 399 high school students. This study used the bifactor model to conceptualize ADHD given that this model provided the best fit when compared to other models of ADHD in the current study and given that there is substantial evidence in the current literature to support the use of this model (Martel, von Eye, & Nigg, 2010). Structural equation modeling results demonstrated that the general factor of ADHD was a significant predictor of life satisfaction when students rated ADHD symptoms, and the inattention factor of ADHD was a significant predictor of life satisfaction when teachers rated ADHD symptoms. In addition, because depressive symptoms have been associated with life satisfaction and inattention, hyperactivity, and impulsivity, the current study examined if life satisfaction moderated or mediated the relationship between inattention, hyperactivity, and impulsivity and depressive symptoms. Results of the present study suggested that life satisfaction serves as a potential but weak moderator in the relationship between general ADHD and depression when symptoms of ADHD were rated by teachers. Results also demonstrated that life satisfaction mediated the relationship between general ADHD symptoms and depressive symptoms when ADHD symptoms were rated by students, and life satisfaction mediated the relationship between inattentive symptoms and depressive symptoms when ADHD symptoms were rated by teachers.
The current study contributes to existing literature on life satisfaction given that there are currently only two studies, one which was conducted with an adult population and one of which was conducted with a middle school population, specifically examining levels of life satisfaction in individuals with symptoms of ADHD. The results of this study provide additional confirmation of the negative relationship between ADHD symptoms and life satisfaction. Moreover, this study was the first to examine how life satisfaction may play a role in the relationship between symptoms of ADHD and depressive symptoms. This study supports that life satisfaction primarily plays a mediating role in the relationship between ADHD symptoms and depressive symptoms and provides support for further examination of this role in future studies.

The learning experiences and preferred teaching strategies of children who have been identified as Gifted with ADHDEdwards, Kylee January 2008 (has links)
This qualitative study investigated the educational and social experiences of six children who had been identified as Gifted with Attention Deficit Hyperactivity Disorder (ADHD). The children were aged from six to ten years old. Semi-structured interviews were conducted with the children and their parents and a staff member of the George Parkyn Centre (now The Gifted Education Centre) to explore their educational and social experiences in order to identify their preferred strategies that were also expected to be the most effective educational strategies. It is important to identify effective educational strategies for Gifted children with ADHD. This is because there are children in New Zealand (as this study has found) who have been identified as Gifted with ADHD but according to the literature review conducted for this study there does not appear to be a significant amount of literature from New Zealand or international writers that informs educators about how to assist these children to learn. Instead, the literature appeared to focus on misdiagnosis of Giftedness as ADHD, however, these children may benefit from having assistance with their learning as some literature suggested they are not being identified and could be underachievers. It seems that the use of effective educational strategies may be the only way these children could reach their academic potential. Therefore, this study sought to move on from the misdiagnosis debate evident in the Gifted/ADHD literature to identify some effective educational strategies. This study also investigated the social experiences of Gifted children with ADHD. This is because the literature maintained Gifted children with ADHD could have difficulties with social interactions. Talking to the children about their social interactions could indicate whether the literature's implications are correct and if they are it should allow further understanding regarding how we could assist the Gifted child with ADHD to have more positive social interactions that could also positively impact on learning as social interactions occur within the classroom. The key findings of this study indicated that some Gifted children with had specific learning preferences that could stimulate them to learn (e.g., when their interests were recognised, information was presented visually, tasks had a meaningful purpose and movement and use of computers was allowed). Ineffective educational strategies were also addressed although not in detail as for the most part they seemed to be the opposite of effective educational strategies. The findings also indicated Gifted children with ADHD could benefit when they find their 'true peer' as this seemed to result in the children within this study wanting to work with others. Although specific suggestions were recommended (e.g., the use Renzulli's 1977 Enrichment Triad Model) the findings emphasised the depth of information that could be gained by simply talking to children and their parents about their learning. A wider implication may be this Gifted group of children may benefit from the use of specific educational strategies that personalise their learning.

The covariation of attention-deficit / hyperactivity disorder and anxiety in children: a community sampleBaldwin, Jennifer S., Psychology, Faculty of Science, UNSW January 2006 (has links)
Attention-Deficit/Hyperactivity Disorder (ADHD) is comorbid with a range of other disorders in clinical and community samples, including anxiety disorders. The outcomes of the Multimodal Treatment Studies of ADHD (MTA Cooperative Group, 1999) highlight the importance of this comorbidity, as children with anxiety responded differently to treatments than did children with ADHD only. At present there are few tested theoretical explanations of the etiological processes and developmental trajectories associated with their co-occurrence. The aim of this research was to put forward and examine different explanations for the comorbidity of these two disorders in children according to the framework provided by Lilienfeld (2003). This was achieved by examining the covariation of ADHD symptoms and anxiety symptoms in a community sample of 499 children aged 8-13. Dimensional assessments of psychopathology were conducted via self-report questionnaires given to children, parents and teachers. The results were analysed via structural equation modelling approaches using AMOS (Arbuckle, 2003). Consistent with the hypotheses, positive associations at Time 1 between ADHD and anxiety symptoms were linked with inattention symptoms and were particularly pronounced for girls. The concurrent positive associations observed at each time period could not be completely accounted for by overlapping symptoms across measures or by method covariance explanations. The link between ADHD and anxiety symptoms could be explained by a common factor in reporting whereby ADHD and anxiety symptoms were both associated with noncompliance and negative affect for parents' reports, and negative affect for children???s' reports. Despite the concurrent associations, there was no support for the hypothesis that ADHD symptoms predicted the development of anxiety symptoms over time, nor the alternative hypothesis that anxiety symptoms predicted the development of ADHD symptoms over time, when the stability of symptoms across time was taken into account. It was concluded that ADHD symptoms (particularly inattention) and anxiety symptoms are covarying phenomena that are linked with common features of an irritable temperament and disruptive behaviour. Future research should investigate the role of these common factors in treatment outcome and cognitive research, which has previously found differences between ADHD children with and without anxiety.

An investigation of the presence of adult attention deficit hyperactivity disorder behaviors in a population of court mandated domestic violence perpetratorsMandell, Allan R. 31 July 1998 (has links)
Sixty-five male volunteers from a court mandated domestic violence treatment program
were administered a questionnaire to assess for the presence of adult attention deficit
hyperactivity disorder (ADHD) behaviors. The questionnaire included copies of the
Wender Utah Rating Scale (WURS) and the Attention Deficit Scales for Adults (ADSA),
as well as demographic information and diagnostic questions assessing previous
professional diagnoses. Results indicated that 93.8% met or surpassed Wender's
suggested cutoff score of 36 indicating the presence of ADHD symptoms, and 64.6% met
or surpassed the higher suggested cutoff score of 46. Twenty-three percent (15) of the
participants met the criteria suggesting the presence of adult ADHD behaviors as
measured by the ADSA. A factor analysis of the WURS resulted in participant scores
loading on four factors suggesting a combination of ADHD and conduct disorder (CD)
behaviors. Results are discussed in light of previous research indicating the WURS'
difficulty in clearly discriminating among disruptive behavior disorders. Implications for
consideration of adult ADHD as a possible predisposing factor in the perpetration of
violence are discussed. Treatment suggestions specifically targeting male DV perpetrators
are offered, such as increased use of experiential exercises, minimizing distractions,
increasing awareness of potential sensitivity to sound levels, and inclusion of stress
reduction techniques. Limitations of this study are discussed in light of instruments
utilized, question wording, and study design. Suggestions are made for further research
with other DV groups from which results are generalizable to the larger DV perpetrator
population. / Graduation date: 1999
