Abstract Objective This study examined whether practice effects caused by repeated exposure to test materials during serial assessment significantly impacts the performance of adults with chronic severe traumatic brain injury (sTBI), given the severe memory impairment typical of this population. This study sought to describe the pattern of practice effects on repeat neuropsychological testing for this population. It was hypothesized that practice effects would be diminished for individuals with chronic sTBI. Method This study utilized longitudinal archival data collected as part of an annual neuropsychological assessment battery administered to 43 individuals receiving post-acute rehabilitation services at a structured multisite day treatment program. Each participant was tested at two time points which differed by an average of 13 months. The battery consisted of the Texas Functional Living Scale (TFLS), Trail Making Test (TMT), Brief Mood Survey, Neuropsychological Assessment Battery (NAB) Screening Module (NAB-SN), and Judgment subtest from the NAB Executive Functions Module (NAB Judgment). Results Practice effects were determined based on reliable improvement (p < .05) in scores across test administrations. A Reliable Change Index (RCI) was calculated for each test based on the method proposed by Jacobson and Truax (1991). Results revealed reliable improvements in performance for the NAB-SN Attention domain (RCI = 3.69), NAB Judgment subtest (RCI = 10.14), and TFLS Total Score (RCI = 4.38). Conclusion This study indicates that adults with chronic sTBI demonstrate significant practice effects primarily on measures associated with functional living skills. These findings suggest that repeat testing in this population may be less susceptible to the influence of practice effects.

This is a brief review of some literature on practice effects and age on neuropsychological testing. Research suggests that younger subjects show greater improvement when retested on intelligence tests than older persons. The implication is that the effects of neuropsychological practice may vary with the age of the person assessed. Suggestions for further research are discussed.

The Global Neuropsychological Assessment (GNA) is an extremely brief battery of cognitive tasks assessing episodic memory, processing speed, working memory, verbal fluency, executive function, and mood. It can be given in under 15 minutes, has five alternate forms, and does not require an examinee to be literate. The purpose of this study was to quantify practice effects over repeated administrations and assess comparability of the GNA’s five alternate forms, preparing the battery for repeated administration in research and clinical settings. Forty participants each completed all five GNA forms at weekly intervals following a Latin square design (i.e., each form was administered at every position in the sequence an equal number of times). In a cognitively intact population, practice effects of 0.56 to 1.06 SD were observed across GNA measures when comparing the first and fifth administration. Most GNA tests showed nonsignificant interform differences with cross-form means differing by 0.35 SD or less, with the exception of modest but statistically significant interform differences for the GNA Story Memory subtest across all five forms. However, post hoc analysis identified clusters of two and three Story Memory alternate forms that were equivalent.

Kinesthetic aftereffect, commonly administered with alternate forms given on two separate occasions, has been used to assess individual differences in personality and perceptual style. Recent criticisms have questioned whether this task gives a worthwhile measure of individual differences. This paper represents a further response to such criticisms by extending to Petrie's alternate-form procedure our argument that lack of test-retest reliability is associated with practice effects which differentially bias second-session scores. Findings indicate that second session bias does occur with this procedure, and, as expected, there was an inverse relationship between magnitude of retest reliability and differential bias. Although use of the alternative-form procedure is contraindicated, a single-session procedure remains a promising personality measure since it is not affected by differential bias.

Objectives: Although clear advances have been achieved in the study of early-onset schizophrenia (EOS), little is known to date about premorbid and prodromal neuropsychological functioning in EOS. Method: Here, we report on a case of an adolescent male with EOS who underwent neuropsychological testing before and after illness onset. Results: Marked cognitive deficits in the domains of attention, set-shifting, and verbal memory were present both pre-onset and during the course of schizophrenia, though only deficits in verbal memory persisted after illness-onset and antipsychotic treatment. Conclusion: The findings of this case study suggest that impairments in the verbal memory domain are particularly prominent symptoms of cognitive impairment in prodromal EOS and persist in the course of the disorder, which further demonstrates the difficult clinical situation of adequate schooling opportunities for adolescent patients with EOS.

Abstract. When concentration tests are completed repeatedly, reaction time and error rate decrease considerably, but the underlying ability does not improve. In order to overcome this validity problem this study aimed to test if the practice effect between tests and within tests can be useful in determining whether persons have already completed this test. The power law of practice postulates that practice effects are greater in unpracticed than in practiced persons. Two experiments were carried out in which the participants completed the same tests at the beginning and at the end of two test sessions set about 3 days apart. In both experiments, the logistic regression could indeed classify persons according to previous practice through the practice effect between the tests at the beginning and at the end of the session, and, less well but still significantly, through the practice effect within the first test of the session. Further analyses showed that the practice effects correlated more highly with the initial performance than was to be expected for mathematical reasons; typically persons with long reaction times have larger practice effects. Thus, small practice effects alone do not allow one to conclude that a person has worked on the test before.

There is new empirical evidence that the effects of impending death on cognition have been miscalculated because of neglect of the incidence of dropout and of practice gains during longitudinal studies. When these are taken into consideration, amounts and rates of cognitive declines preceding death and dropout are seen to be almost identical, and participants aged 49 to 93 years who neither dropout nor die show little or no decline during a 20-year longitudinal study. Practice effects are theoretically informative. Positive gains are greater for young and more intelligent participants and at all levels of intelligence and durations of practice; declines in scores of 10% or more between successive quadrennial test sessions are risk factors for mortality. Higher baseline intelligence test scores are also associated with reduced risk of mortality, even when demographics and socioeconomic advantage have been taken into consideration.
