Development of complex executive function over childhood
This longitudinal study modeled children's complex executive function (EF) development using the Groton Maze Learning Task (GMLT). Using a cohort-sequential design, 147 children (61 males, 5.5–11 years) were recruited from six multicultural primary schools in Melbourne and Perth, Australia. Race/ethnicity data were not available. Children were assessed on the GMLT at 6-month intervals over 2-years between 2010 and 2012. Growth curve models descri…
Development of a new virtual reality test of cognition
Background Technological advances provide an opportunity to refine tools that assess central nervous system performance. This study aimed to assess the test-retest reliability and convergent and ecological validity of a newly developed, virtual-reality, concussion assessment tool, ‘CONVIRT’, which uses eye-tracking technology to assess visual processing speed, and manual reaction time (pushing a button on a riding crop) to assess attention and de…
Clinical utility of the cogstate brief battery in identifying cognitive impairment in mild cognitive impairment and Alzheimer’s disease
Results of this study suggest that the CogState learning/working memory composite score is reduced significantly in CI and AD, correlate well with measures of disease classification and are useful in identifying memory impairment related to MCI- and AD
Assessment of cognition in an adolescent Indigenous population
The assessment of cognition in Indigenous populations is often complicated by cultural and language differences and unfamiliarity with the assessment process. Cognitive tasks are being developed that reduce the impact of these factors. These processes need to be evaluated in different cultural and ethnic groups to determine whether they are appropriate. Such an assessment was recently used in two studies of cognition of 237 Indigenous Australian …
Reliability of repeated cognitive testing in healthy Indigenous Australian adolescents
Serial assessment is required in situations where decline or recovery of function is anticipated. Serial assessment of cognition in Indigenous populations, however, can be problematic due to a lack of culturally appropriate assessments with psychometric properties suitable for repeated administration. This study assessed a non-verbal, culturally neutral, computerised cognitive test battery for its test–retest reliability and any practice effects …
Hunger and the perception of the scent of petrol
The deliberate inhalation of petrol as a means of intoxication used by underage and marginalized social groups is a growing international problem. This type of abuse has been identified as the cause of severe physical, cognitive, and psychological impairment. Both of these factors have heightened the need for identifying causes underlying why individuals begin abusing petrol. One hundred Australian male adults were surveyed while they were fillin…
Measuring Exposure to Cannabis use and other Substance use in Remote Aboriginal Populations in Northern Australia
We evaluate a method to describe changing substance use patterns in northern Australia's remote Aboriginal communities (Arnhem Land, Northern Territory). Substance use was assessed in random samples in two communities A (n = 194) and B (n = 176). Five Aboriginal health workers made assessments independently of each other in community A. A different group of three health workers made independent assessments in community B. Sub-samples were opportu…
Validation of an Internet delivered and analysed test of cognitive function for use in web based psychology courses
In this study we investigated the use of Internet technologies for administering and analysing a test of cognitive function in a web based psychology course. The aim was to determine whether the cognitive test actually measured the same functions when administered in three different settings: a supervised university based laboratory , an unsupervised university based laboratory, and a remote (or off campus) setting. Results showed that the differ…
The Effects of Age and Mood on Saccadic Function in Older Individuals
To investigate the effect of age and mood on saccadic function, we recorded prosaccades, predictive saccades, and antisaccades from 238 cognitively normal, physically healthy volunteers aged 44 to 85 years old. Mood levels were measured using the State-Trait Anxiety Inventory and Center for Epidemiological Studies Depression Scale inventories. Small, but significant, positive relationships with age were observed for the mean latency and associate…
Computer-Administered Visual Analogue Mood Scales
Studies of cognition in patients with the human immunodeficiency virus must take into account the effects of mood. Standardised mood-rating questionnaires are oftentimes consuming and fatiguing for such patients and so may be omitted from experiments. Visual analogue rating scales for affective state are rapidly administered and are quite acceptable to subjects. In 64 HIV seropositive homosexual or bisexual males, measures of anxiety and depressi…
