A comparison of mildly head-injured, malingering, and non-head-injured adult South Africans : neuropsychological performance and post-concussion symptoms.Kuun, Terence Michael January 1998 (has links)
A dissertation submitted to the Faculty of Arts, University of the Witwatersrand, in partial fulfilment of the requirements of the degree of Master of Arts / The study reviews the literature concerning mild head
injury and post concussion symptoms. It then investigates
the applicability of international findings to South
African patients. Three groups of subjects are compared:
mildly injured, noninjured, and instructed malingerers. The
study establishes base rates of postconcussive symptoms in
the noninjured subjects, scores on tests of cognitive
ability among the noninjured subjects, expectations
regarding postconcussive sequelae among the noninjured
subjects, the perceptions of injured subjects of their preand
postmorbid status, and relationships between
subjectively experienced symptoms and cognitive deficits
am.ong injured subjects. Injured subgroups are examined to
investigate pre-, peri-, and post-injury factors associated
with development of postconcussive complaints. No
differences in cognitive performance were found between the
injured and noninjured groups. Time since injury did not
affect cognitive performance, apart from on a copy task. It
was found that injured subjects reported lower pre-injury
levels of incidence of symptoms than those reported by
noninjured subjects. No differences were found between
post-injury reporting of postconcussive complaints and
those symptoms reported by noninjured controls. Some
postconcussive symptoms were nevertheless found to
correlate with certain measures of cognitive performance.
Instructed malingerers responded differently noninjured injured and not injured subjects, reporting fewer pre-injury complaints and mere post-injury complaints. They also performed more poorly on several cognitive measures. Test scores that effectively identified malingerers were then re-examined, and cut-off rates suggested for differentiating malingerers from genuinely injured subjects. / Andrew Chakane 2018

Kwantifisering van derdeparty versekeringseise: die rol van die bedryfsielkundige / The quantifying of third party insurance claims: the industrial psychologists roleMoodie, B.(Benjamin) 06 1900 (has links)
Summary in Afrikaans and English / Against the background of the volume of Third Party Claims instituted annually and
considering the cost involved therein, it has become increasingly important that
Industrial Psychologists be consulted to assist in the quantifying of such claims.
From an Industrial Psychologist's view, these claims can be quantified by making
use of certain Industrial Psychology techniques. These techniques include
psychometrical evaluation, applying the knowledge on:- training, job analysis,
interviewing and guidance, career planning and ergonomics. The purpose of this study was to liaise with the Legal Profession to identify the
requirements and problem areas experienced in the establishing and quantifying of
Third Party Insurance Claims. The needs thus identified served as the basis for
this study.
In the process of defining and categorising these problems, it became apparent that
these requirements could be addressed satisfactorily by Industrial Psychologists.
It was therefore possible also to determine whether Industrial Psychology as a
Science, could contribute to solving these problems. To determine therefore whether Industrial Psychology could actually address and
solve these problems and whether the Courts would recognise the contribution of
Industrial Psychologists, an actual case study was made of a matter where two
Industrial Psychologists had made evaluations.
Researching the methods of evaluations employed, and viewing the finding of the
Court thereafter, it became apparent that Industrial Psychology can satisfy the need
encountered by the legal profession therein. It is further concluded that the curriculum of Industrial Psychology may be
successfully applied as an accepted Science in the quantifying of Third Party
Insurance Claims. / Teen die agtergrond van die hoeveelheid derdepartyeise wat jaarliks ingedien word,
met inagneming van die koste verbonde, word dit toenemend belangrik dat
bedryfsielkunde behulpsaam moet wees met die kwantifisering van sulke eise.
Vanuit 'n bedryfsielkundige oogpunt kan hierdie eise gekwantifiseer word deur
gebruik te maak van sekere bedryfsielkundige tegnieke. Hierdie tegnieke sluit in,
psigometriese evaluering, kennis oor opleiding, posontleding, onderhoudvoering en
voorligting, loopbaanbeplanning en ergonomika. / Industrial and Organisational Psychology / M. Com. (Industrial and Organisational Psychology)
