Determinants and correlates of intra-individual variability in reaction time
… speed of a number of responses made by an individual, or mean RT. Increasingly, however, intraindividual variability in reaction time (RT IIV) – the consistency of responses by a single person across trials – is used as an additional or even alternative measure. RT IIV is often found to be …

Intra-individual variability in adult ADHD: an exploration of the viability of distinct purely inattentive condition
Researchers have suggested that intraindividual variability (IIV), or variation in cognitive testing performance within an individual across a measure or group of measures, may be an endophenotypic marker of Attention-Deficit/Hyperactivity Disorder (ADHD). However, not all studies have consistently …

Characterising the structural brain connectome in Alzheimer's disease and its relation to cognitive intra-individual variability.
… imaging (DTI) as well as increased reaction time intra-individual variability (RT IIV) on neurocognitive testing. However, the relationship between these changes measured on these different modalities remains unexplored. To explore possible relationships between these alterations, this study used …

Title Investigation of the moral reasoning of offending and non-offending adolescents using the sociomoral reflection measure-short form
… to the Gilligan hypothesis. Patterns of intra-individual variability in moral stage use were also investigated to test claims regarding structural consistency in moral reasoning. It was found that participants were demonstrating intra-individual variability in their patterns of moral …

Characterising social cognition and its predictors in individuals with premanifest Huntington’s disease
… (DSM-5). Deficits have been reported in individuals with HD across four social cognitive domains: theory of mind, social perception, empathy and social behaviour. Social cognitive impairment may cause difficulty in maintaining social relationships, work performance and increased …

Nutritional factors associated with obesity in adolescent females in the United Arab Emirates
… by the phases of the menstrual cycle. The wide intra-individual variability in basal metabolic rate during the menstrual cycle may explain why women may be more prone than men to become obese.

Population pharmacokinetics: model-free approach and nonlinear mixed-effects modelling
… predictors of exposure in a wide range of variability in the data. The non-linear mixed effect modelling is used to confirm the results of the model-free investigation. Model-free approach is successfully applied to several drugs. Non-linear Mixed Effects population models developed for the …

The contribution of divided attention to tripping while walking
… allowed an estimation of the likelihood of an individual tripping on unseen obstacles while walking. Since cognitive decline and reduced ability to multitask (reduced divided attention capacity) has been observed in older adults and has been linked to falls risk, this research also examines …

Relationships between running economy and mechanics in middle-distance runners
… Special emphasis was given to accounting for intra-individual variability in RE at different speeds and to assessing track running rather than treadmill running. In Study One, a factor analysis was used to reduce the 30 considered mechanical parameters to few global descriptors of the running …

An Investigation into Children’s Out-of-School Physical Activity
… and family context. Study 5 revealed substantial intra-individual variability in children’s weekend MVPA. PA diary data revealed that children's weekend PA was mostly unstructured in nature and undertaken with friends, whereas a greater proportion of parents’ weekend PA was undertaken alone in …

Predicting independent functioning in an elderly population: the evaluation of working memory capacity as a biomarker of ageing.
… an ageing population. Due to increases in inter-individual and intra-individual variability with age, chronological age has been demonstrated to be a poor predictor of an individual's functional ability (Bauco et al, 1996; Willis et al., 1992). Consequently, other, more successful indicators, …

THE IMPACT OF CYP3A4*22 AND CYP3A5*3 ON DEXAMETHASONE AND 6-HYDROXY-DEXAMETHASONE PHARMACOKINETICS IN PHASE 1/2 CANCER PATIENTS
… marketed drugs. However, their 10-100 fold inter-individual variability in activity may have a profound effect on outcomes from drug therapy. CYP3A4*22 and CYP3A5*3 have been shown to significantly affect CYP3A4/5 activities and pharmacokinetics of various CYP3A4/5 substrates. Dexamethasone is a …
