Comparison of scores from the Wechsler Adult Intelligence Scale–IV and the Woodcock Johnson III in an Australian university sample
Objective This study investigates, in an Australian university student sample, the score equivalence of the Wechsler Adult Intelligence Scale-IV (WAIS-IV) norms for which are based on the US standardization sample versus the Woodcock Johnson III (WJ III) cognitive test battery, normed for the Australian population based on a standardisation sample aged between four and twenty-one. Mean IQ scores in the two instruments were compared in sample scor…
Origins of Neuropsychology Research and Teaching at the University of Melbourne, Australia
The University of Melbourne hosts a well-known graduate training program in clinical neuropsychology, which was the first formal training program in neuropsychology established in Australia. What is less well known is that neuropsychology research has a much longer history at the University of Melbourne, beginning in the second decade of the 20th century. This chapter briefly traces the early history, which centered on collaborations between staf…
Exploring the reliability and acceptability of cognitive tests for Indigenous Australians
RUDAS, CogState Identification task, and SMRT showed the highest reliabilities. Overall the tests were viewed as a positive challenge and an opportunity to learn about the brain despite provoking some anxiety in the patients. Caveats for test acceptability included issues related to language, impacts of convalescence and cultural relevance
Maternal micronutrient consumption periconceptionally and during pregnancy
Objective To examine overall micronutrient intake periconceptionally and throughout pregnancy in a population-based cohort of Australian women. Design In a prospective cohort study, micronutrient dosages were extracted from self-reported maternal supplement use, recorded pre-conception, and for each trimester of pregnancy. A food frequency scale (DQESv2) captured usual maternal diet for gestational weeks 14–26. The influence of sociodemographic a…

ObjectiveThis study aimed to determine the incremental validity of the Minnesota Multiphasic Personality Inventory, Second Edition (MMPI‐2), relative to the Beck Depression Inventory‐Second Edition (BDI‐II) in the detection of depressive symptoms in neurological patients. An additional aim was to determine whether over‐reporting and under‐reporting as measured by the MMPI‐2 validity scales, predicted BDI‐II scores.MethodThe sample comprised 406 c…
Invariance of the Measurement Model Underlying the Wechsler Adult Intelligence Scale-IV in the United States and Canada
A measurement model describes both the numerical and theoretical relationship between observed scores and the corresponding latent variables or constructs. Testing a measurement model across groups is required to determine if the tests scores are tapping the same constructs so that the same meaning can be ascribed to the scores. Contemporary tests of intelligence describe a number of closely related cognitive abilities, each ability being sampled…
Invariance of the Measurement Model Underlying the Wechsler Adult Intelligence Scale—III in the United States and Canada
A measurement model is invoked whenever a psychological interpretation is placed on test scores. When stated in detail, a measurement model provides a description of the numerical and theoretical relationship between observed scores and the corresponding latent variables or constructs. In this way, the hypothesis that similar meaning can be derived from a set of test scores can be tested by examination of a measurement model across groups. This s…
Latent Mean and Covariance Differences With Measurement Equivalence in College Students With Developmental Difficulties Versus the Wechsler Adult Intelligence Scale–III/Wechsler Memory Scale–III Norma…
Intelligence tests are usually part of the assessment battery for the diagnosis of adults with learning disabilities (LD) and attention deficit hyperactivity disorder (ADHD). Professionals must ensure that inferences drawn from such test scores are equivalent across populations with and without disabilities. Examination of measurement equivalence provides a direct test of the hypothesis that the same set of latent variables underlies a set of tes…
Accuracy of the Wechsler Test of Adult Reading (WTAR) and National Adult Reading Test (Nart) when estimating IQ in a healthy Australian sample
The recently published Wechsler Test of Adult Reading (WTAR) has been co-normed with the third editions of the Wechsler Adult Intelligence and Memory Scales (WAIS-III, WMS-III), and has been shown to reliably estimate intelligence in U.S. and U.K. samples. However, the suitability of the WTAR for use in Australia has not been established, nor is there any clear basis for determining whether to use U.S. or U.K. norms to convert WTAR raw scores to …
Normative data for Australian midlife women on category fluencyand a short form of the Boston Naming Test
This study presents Australian normative data for verbal fluency and visual confrontational naming for midlife women and examines factors that mediate verbal performance in this population. Two hundred and fifty-seven healthy Australian-born women aged 56 – 67 years who participated in the Melbourne Women's Midlife Longitudinal Health Project were assessed for verbal fluency and visual confrontational naming. Verbal fluency was assessed using the…
Normative visuospatial performance in Australian midlife women
This paper presents normative data for visual – spatial ability in midlife Australian women. Understanding normative performance on visuospatial tasks has gained increasing importance recently with the emergence of the association between Alzheimer's disease and impairments in visuo-constructional skills and judgments of spatial relations. Thus, the availability of relevant local normative data is critical as a valid reference source in the clini…
Normative data for tasks of executive function and working memory for Australian-born women aged 56 – 67
Normative data for tests of working memory and executive function (a term adopted to cover a range of cognitive skills) are primarily based on the U.S. population and are not always specific for gender or education levels. The diagnosis of, and research into, cognitive diseases rely on the use of relevant normative data. This study presents normative data for an ageing, female, Australian-born population, and an analysis of the factors that contr…
Utilising the Wais-III/WMS-III in clinical practice
The latest versions of the Wechsler Adult Intelligence Scale (WAIS) and Wechsler Memory Scale (WMS) offer some decided advantages over the previous versions. This article discusses the research on the updated versions of the tests with reference to the continuity of construct validity across versions. In addition, there have been some concerns reported about the use of the WAIS-III and WMS-III in Australia due to the absence of local norms. These…
Money Laundering
This paper aims to draw attention to the key issues in combating money laundering and possible action that could be taken on a coordinated basis. It suggests measures to strengthen the financial sector, considers practical issues involved in combating money laundering in international financial centres and the problems of economic crime and tackling money laundering in the parallel economy. It concludes with a series of action steps which were su…
Using Logical Memory in Australia
Australian neuropsychologists, who use tests developed in North America such as Wechsler's Memory Scales, have expressed some concerns about the relevance of test materials for Australian clients. In Australia, concern about the American content of Logical Memory prompted Ivison to recommend modifications to adapt this test for local conditions. Consequently, when Australian psychologists administer Logical Memory they may be using Wechsler's sto…
Hypothesis-Testing in Australian Neuropsychology
Within neuropsychology, there are a variety of approaches to clinical hypothesis-testing. Originally, clinical hypothesis-testing was defined in terms more akin to what is now know as single-case experimentation. However, in Australia, the term hypothesis-testing has come to be associated with a clinical style which places strong emphasis on expeditious assessment of the clinical management problem or referral question, and strong emphasis on exp…
What does the austin maze measure
The Austin Maze is a version of a popular neuropsychological test which is employed, internationally, as a measure of spatial memory. However, in Australia, failure to attain errorless performance within a limited number of trials on the Maze is often interpreted as evidence of frontal lobe dysfunction. Such a result might then be used to make predictions about a client's potential for rehabilitation or a successful return to work. Moreover, a cl…
Separating cognitive impairment in neurologically asymptomatic alcoholism from Wernicke-Korsakoff syndrome
Recent studies that have combined neuropathological data and clinical histories in a retrospective fashion have shown that Wernicke-Korsakoff neuropathology is often unsuspected antemortem and that, in terms of clinical presentation, it is more heterogeneous than previously assumed. Thus, many studies of neurologically normal alcoholics may have been confounded by the inclusion of patients with neurologically asymptomatic Wernicke-Korsakoff neuro…
