Abstract Objective Both anxiety and traumatic brain injury (TBI) are both related to poorer Trail Making Test (TMT) performances. TBI survivors exhibit a greater incidence of anxiety in contrast to the general population. We evaluated the relationship between TBI and anxiety on TMT and perceived workload ratings. Method The sample consisted of 39 moderate-to-severe TBI [(21 with normal symptoms of anxiety (NSA) and 18 with abnormal symptoms of anxiety (ASA)] and 51 healthy comparison (HC; 26 NSA and 25 ASA) participants. Results ANCOVA’s, controlling for age, revealed the HC group outperformed the TBI group on TMT part A and TMT part B (TMT-B). An interaction emerged on TMT-B, with TBI-ASA participants outperformed TBI-NSA participants and HC-NSA participants outperformed their counterparts with ASA. Ratings of physical demand and frustration were reported higher in TBI participants compared to the HC participants. Moreover, TBI and anxiety symptoms had interactive effects on NASA-TLX temporal demand and frustration ratings, were TBI-ASA participants reported higher scores in contrast to TBI-NSA. Lastly, an interaction emerged with HC participants with ASA reporting better performances in contrast to HC-NSA. Conclusions As expected, TBI participants did worse on both TMT tasks. Next, we found that TBI-ASA participants impacted their TMT-B performance and their perceived workload (i.e., frustration, temporal demand) more than TBI-NSA participants. In the future, studies with a larger sample size should examine if anxiety influences TMT performance and perceived workload in person with mild TBI.

The Trail Making Test (TMT) is widely used in neuropsychological practice as part of a battery for detecting neuropsychological dysfunction. A comprehensive review published by Horton in 1979, focused on adult performance. A critical evaluation of research investigating the use of this test in children is presented here. No clear set of instructions for test use is available for children and, while some aspects of neuropsychological function are similar for adults and children, other factors set these groups apart. Norms are not readily available for children and the relationship of test performance to age, education level and IQ in adults suggests that these are critical variables, particularly in South Africa.

AbstractObjectives: Hazard perception, the ability to identify and react to hazards while driving, is of growing importance in driving research, given its strong relationship to real word driving variables. Furthermore, although poor hazard perception is associated with novice drivers, recent research suggests that it declines with advanced age. In the present study, we examined the neuropsychological correlates of hazard perception in a healthy older adult sample. Methods: A total of 68 adults age 60 and older who showed no signs of dementia and were active drivers completed a battery of neuropsychological tests as well as a hazard perception task. Tests included the Repeatable Battery for the Assessment of Neuropsychological Status, Wechsler Test of Adult Reading, Trail Making Test, Block Design, Useful Field of View, and the Delis-Kaplan Executive Function System Color Word Interference Test. Results: Hazard perception errors were related to visuospatial/constructional skills, processing speed, memory, and executive functioning skills, with a battery of tests across these domains accounting for 36.7% of the variance in hazard perception errors. Executive functioning, particularly Trail Making Test part B, emerged as a strong predictor of hazard perception ability. Conclusions: Consistent with prior work showing the relationship of neuropsychological performance to other measures of driving ability, neuropsychological performance was associated with hazard perception skill. Future studies should examine the relationship of neuropsychological changes in adults who are showing driving impairment and/or cognitive changes associated with Mild Cognitive Impairment or dementia.

Background.Continuous electroencephalography (CEEG) monitoring is used for detection of convulsive and nonconvulsive seizures and assessing the degree of encephalopathy in critically ill patients. A commonly seen encephalopathic pattern on CEEG is generalized periodic discharges with triphasic wave (TW) morphology. The underlying role and prognostic significance of TW in relationship to intracranial pressure (ICP) remain unknown. We present a case highlighting the relationship of TW with ICP in a case with severe traumatic brain injury (TBI).Method.Case report.Results.A patient with severe TBI and no underlying metabolic abnormalities was admitted to the neurocritical care unit. TW were seen on CEEG. The TW diminished during episodes of intracranial hypertension but reappeared with reduction of the intracranial pressure.Conclusion.This study highlights a possible favorable prognostic marker of finding TW in a patient with intracranial hypertension. We have proposed a preliminary understanding of the relationship between TW and intracranial hypertension, which may be helpful in formulating future studies involving larger cohorts.

Abstract This four-part series of papers addresses the problem of systematic determination of the influence of several tire factors on tire treadwear. Both the main effect of each factor and some of their interactive effects are included. The program was also structured to evaluate the influence of some external-to-tire conditions on the relationship of tire factors to treadwear. Part I describes the experimental design used to evaluate the effects on treadwear of generic tire type, aspect ratio, tread pattern (groove or void level), type of pattern (straight rib or block), and tread compound. Construction procedures and precautions used to obtain a valid and functional test method are included. Two guiding principles to be used in the data analyses of Parts II and III are discussed. These are the fractional groove and void concept, to characterize tread pattern geometry, and a demonstration of the equivalence of wear rate for identical compounds on whole tread or multi-section tread tires.

Focal Issue

Purpose This study aims to propose a framework based on the main theoretical and empirical contributions present in the literature and articulate the main paths for future studies in knowledge-intensive entrepreneurship (KIE). Design/methodology/approach Using the systematic review method from a survey of 85 articles, related to the KIE focal issue, originated from the Web of Science, it was possible to exhaustively analyze the studies and to divide the theme into key categories. Findings The present research has raised the relationship of five categories to KIE conceptualizations; the data suggest that although the literature indicates a distancing from KIE research, there are multidisciplinary themes and approaches interlinked in the studies. Originality/value The systematic approach in the main theoretical and empirical contributions in KIE enabled us to relate five categories (entrepreneurs, innovation, internationalization, location and triple alliance), and finally, to understand the gaps suggested by the researchers.

The Relationship

Abstract Objective We evaluated perceived workload (measured by the NASA Task Load Index; NASA-TLX) as related to Symbol Digit Modalities Test (SDMT) performances in monolingual and bilingual traumatic brain injury (TBI) survivors and healthy comparison participants (HC). Method The sample consisted of 28 TBI survivors (12 monolinguals & 16 bilinguals) and 50 HC (20 monolinguals & 30 bilinguals). SDMT written (SDMT-W) and SDMT oral (SDMT-O) were used to evaluate group differences. Results ANCOVA, controlling for age, revealed that the HC group outperformed the TBI group on SDMT-W, p = .001, and SDMT-O, p = .047. Furthermore, bilinguals outperformed monolinguals on SDMT-W, p = .017. On the NASA-TLX, an interaction emerged on temporal demand rating, p = .023, with TBI bilinguals reporting higher temporal demand on SDMT tasks compared to TBI monolinguals, while the HC monolingual participants reported higher temporal demands ratings compared to HC bilingual participants. Furthermore, monolingual participants showed higher levels of frustration with regard to the SDMT task compared to bilingual participants, p = .029. Conclusion Our data revealed TBI survivors underperformed on both SDMT trials compared to the HC participants. Also, bilingual participants demonstrated better SDMT-W performances compared to monolingual participants. Furthermore, our TBI bilingual sample reported themselves to be more rushed to complete the SDMT compared to monolingual TBI sample, but they were less frustrated. Meanwhile, our HC monolingual sample felt more rushed to complete the SDMT tasks compared to HC bilingual participants, but they were less frustrated. While we observed differences in workload ratings between language groups, it is unclear if language use, and/or other variables are driving these results.
