Abstract
Hierdie studie ondersoek die moontlikheid dat aandagtekort
versteuring met hiperaktiwiteit(ATHV/H) verband hou met probleme
met voortgesette aandag, terwyl aandagtekort versteuring sander
hiperaktiwiteit(ATHV/SO) verband hou met probleme met gefokusde
aandag. Neurosielkundige toetse waarmee voortgesette- en
gefokusde aandag gemeet word, word gebruik om drie groepe,
naamlik ATHV/H(n=24), ATHV/SO(n=l5) en 'n kontrole groep(n=21),
met mekaar te vergelyk. Resul tate dui daarop dat die groep
ATHV/SO beduidend swakker presteer as die ander twee groepe op
sommige van die toetse van gefokusde aandag, en ook neig om
swakker te presteer op die toets van voortgesette aandag. Die
groep ATHV/SO se probleme blyk gekoppel te wees aan 'n stadiger
spoed van kognitiewe prosessering en 'n toestand van hipoopwekking.
Die groep ATHV/H presteer nie beduidend swakker as
die ander twee groepe op die toets van voortgesette aandag nie,
maar presteer wel swakker as die kontrole groep op die Stroop
Colour-Word Test waar inhibisie van ontoepaslike response vereis
word. Die groep ATHV /H se probleme blyk verband te hou met
frontale disfunksie wat manifesteer as 'n neighing tot impulsiwiteit en gebrekkige gedragsregulering.
This study examined the possibility that attention deficit disorder with hyperactivity(ADHD/H) is related to problems with sustained attention, while attention deficit disorder without hyperactivity (ADHD/WO) is related to problems with focussed attention. The performance of three groups: ADHD/H (n=24), ADHD/WO(n=15) and a control group(n=21) were compared. Results indicated that the ADHD/WO group performed significantly poorer than the other two groups on some of the tests of focussed attention and also tended to perform poorer on the test assessing sustained attention. This groups' symtoms appear to be related to a slowed speed of processing and a state of hypo-arousal. The ADHD/H group did not perform poorer than the other two groups on the test assessing sustained attention. The ADHD/H groups' symptoms appear to be related to frontal dysfunction resulting in impulsivity and poor behavioural control.
