AbstractThe Relative Consequence Model proposes multiple sclerosis (MS) patients have a fundamental deficit in processing speed that compromises other cognitive functions. The present study examined the mediating role of processing speed, as well as working memory, in the MS-related effects on other cognitive functions for early relapsing-remitting patients. Seventy relapsing-remitting MS patients with disease duration not greater than 10 years and 72 controls completed tasks assessing processing speed, working memory, learning, and executive functioning. The possible mediating roles of speed and working memory in the MS-related effects on other cognitive functions were evaluated using structural equation modeling. Processing speed was not significantly related to group membership and could not have a mediating role. Working memory was related to group membership and functioned as a mediating/intervening factor. The results do not support the Relative Consequence Model in this sample and they challenge the notion that working memory impairment only emerges at later disease stages. The results do support a mediating/intervening role of working memory. These results were obtained for early relapsing-remitting MS patients and should not be generalized to the broader MS population. Instead, future research should examine the relations that exist at other disease stages. (JINS, 2013, 19, 1–12)

Abstract Objective The aim of this study was to determine whether a correlation exists between reading fluency in the WJ-IV ACH and processing speed in the WISC-V. Method The data for this study was derived from a large de-identified database. Participants (n = 90) included individuals who completed the Wechsler Intelligence Scale for Children Fifth Edition (WISC-V), which measures intellectual ability, and the Woodcock Johnson IV Tests of Achievement (WJ-IV ACH), which tests for reading, writing, and mathematic achievement. The participants consisted of 36.7% White, 20% Black, 31.1% Hispanic, and 12.2% Other. From the sample, 66.7% were male and 32.3% were female. All the participants were administered the WISC-V and WJ-IV ACH (mean age = 10.53, SD = 2.50; mean education = 4.6, SD = 2.47). Vocabulary was controlled for. Results The results indicated a significant correlation between the WJ-IV ACH Reading Fluency and the WISC-V Processing Speed Index r(87) = 0.326, p = 0.002. Conclusions Previous research has found that deficits in processing speed affect reading efficiency. Cognitive processes are affected even in children with ADHD who are able to decode words accurately. Processing speed, specifically Coding in the WISC-IV, was found to be significantly associated with verbal span and measures of working memory. Moreover, processing speed and working memory have been found to be significant predictors of oral reading fluency (Jacobson et al., 2011). The current findings confirm a correlation between processing speed and reading fluency in updated versions of the forementioned assessments. Future research should investigate the role of comorbid diagnosis found in the functioning of both processing speed and reading fluency.

Disorders of reading, math, and attention frequently co-occur in children. However, it is not yet clear which cognitive factors contribute to comorbidities among multiple disorders and which uniquely relate to one, especially because they have rarely been studied as a triad. Thus, the present study considers how reading, math, and attention relate to phonological awareness, numerosity, working memory, and processing speed, all implicated as either unique or shared correlates of these disorders. In response to findings that the attributes of all three disorders exist on a continuum rather than representing qualitatively different groups, this study employed a dimensional approach. Furthermore, we used both timed and untimed academic variables in addition to attention and activity level variables. The results supported the role of working memory and phonological awareness in the overlap among reading, math, and attention, with a limited role of processing speed. Numerosity was related to the comorbidity between math and attention. The results from timed variables and activity level were similar to those from untimed and attention variables, although activity level was less strongly related to cognitive and academic/attention variables. These findings have implications for understanding cognitive deficits that contribute to comorbid reading disability, math disability, and/or attention-deficit/hyperactivity disorder.

Effect Of Age

ABSTRACTBackground:The effects of age on the ability to manage everyday functioning, crucial to ensure a healthy aging process, have been rarely examined and when, self-report measures have been used. The aim of the present study was to examine age effects across the adult lifespan in everyday functioning with two performance-based measures: the Everyday Problems Test (EPT), and the Timed Instrumental Activities of Daily Living (TIADL) tasks. The role of some crucial cognitive abilities, i.e. working memory (WM), processing speed, reasoning, vocabulary, and text comprehension in the EPT and the TIADL were also assessed to see whether or not they have a similar influence (and to what extent) in accounting for age-related effects in these two performance-based measures.Method:Two hundred and seventy-six healthy participants, from 40 to 89 years of age were presented with the EPT, the TIADL, as well as WM, processing speed, reasoning, text comprehension, and vocabulary tasks.Results:Path models indicated an indirect effect of age and education on the EPT, which was mediated by all the cognitive variables considered, with WM and reasoning being the strongest predictors of performance. An indirect quadratic effect of age, but not of education, was found on the TIADL score, and an accelerated decline in processing speed mediated the relationship between age and the TIADL score.ConclusionThis study revealed age-related effects in performance-based measures, which are mediated by different cognitive abilities depending on the measure considered. The findings highlight the importance of assessing everyday functioning even in healthy older adults.
