Cognitive phenotypes in patients with relapsing-remitting multiple sclerosis with different disease duration, applying the international classification of cognitive disorders in MS (IC-CoDiMS).

Objective: Cognitive impairment is experienced by 40-70% of multiple sclerosis patients, with information processing speed and memory most affected. Until now, cognitive results classified patients as impaired and not impaired. With this dichotomous approach, it is difficult to identify, in a heterogeneous group of patients with cognitive impairment, which cognitive domain(s) are most altered. This study aims to identify cognitive phenotypes in a clinical cohort of adult patients with Relapsing-Remitting Multiple Sclerosis (RRMS) using the International Classification of Cognitive Disorders in MS (IC-CoDiMS) and to characterize their clinical features. Methods: Three hundred patients with RRMS underwent neuropsychological assessment with the Brief Repeatable Battery of Neuropsychological Tests (BRBN-T) and the Brief International Cognitive Multiple Sclerosis (BICAMS). Results: In our cohort, the mean age was 41.38 [11.48 SD] years, and 205 [68.3%] were women. At the -1 SD threshold, 49% were cognitively intact, 25% had uni-domain impairment, 17% had bi-domain impairment, and 9% had multi-domain impairment. Processing speed was the most frequent single-domain impairment, followed by memory and verbal fluency. At the -1.5 SD threshold, 74.7% were cognitively intact, 17% had uni-domain impairment, 6% had bi-domain impairment, had bi-domain impairment, and 3.0% had multi-domain impairment. Memory was the most frequent single-domain impairment, followed by processing speed and verbal fluency. Conclusions: This study corroborates the importance of determining cognitive phenotypes through taxonomy (IC-CoDiMS). In addition, it contributes to improving the classification of cognitive phenotypes in patients with RRMS to enhance the development of more effective treatments and cognitive interventions.

Reactivity of the triple task on writing processes and product in adults with dyslexia.

Introduction: The triple task (TT) is a method for assessing the dynamics of writing processes. It involves three tasks in one: writing a text, responding to a sound, and reporting the process. Previous research has mostly shown that the TT does not affect the writing process or the product. However, individuals with dyslexia often show difficulties in tasks that require organization, automation, integration of multiple processes, inhibition, and shifting/cognitive flexibility. The aim of this study was therefore to investigate whether TT affects the writing process and written product differently in adults with dyslexia compared to a control group of adults with typical reading skills. Methods: Two groups of adult native Croatian speakers were included in this study: 20 adults with developmental dyslexia and 20 adults with typical reading skills; evenly distributed by: age (18-38 years), gender (13 males, 7 females per group), educational level, and nonverbal cognitive abilities. All participants wrote one text with a TT and another without. The writing of the text was tracked with a keystroke logging program - Inputlog. The two texts were compared at process and product level. Results and discussion: The results showed that measures of writing processes and text quality in the groups of adults with dyslexia and adults with typical reading skills were unlikely to be differentially affected by TT. However, in the condition without TT, the total number of characters per minute was higher, more keys were typed per minute and more words were deleted. As expected, adults with dyslexia produced shorter texts of lower quality and with more errors; they also produced fewer characters per minute, used fewer keystrokes and typed fewer. Conclusion: The study suggests that TT is unlikely to have a different impact on the writing process or written product in adults with dyslexia compared to adults with typical reading skills.

Cognitive impairment in multiple sclerosis phenotypes: Neuropsychological assessment in a portuguese sample.

BACKGROUND: Cognitive impairment affects 40-65% of MS patients, encompassing all disease stages and types of clinical courses. This estimation is based on different instruments used and population normative data. OBJECTIVE: This study aims to assess the cognitive function in a hospital-based cohort of Portuguese MS patients, to allow estimating the prevalence of cognitive impairment in different phenotypes. METHODS: Three hundred and thirteen patients with Multiple Sclerosis (MS) underwent neuropsychological assessment with the brief repeatable battery of neuropsychological tests (BRBN-T) and the brief international cognitive assessment for multiple sclerosis (BICAMS). RESULTS: Differences were observed in the cognitive impairment profile of different disease phenotypes and of the different disease severity stages. RRMS patients performed better in the cognitive test of the BRBN-T and BICAMS than those with progressive disease phenotypes. Relationships between cognitive impairment and disability and professional status were relevant. Although similarities could be observed in the cognitive profile of the MS phenotypes, with predominant involvement of verbal memory, verbal fluency, and information processing speed, the latter was found to be more frequent as the disease progressed. CONCLUSION: This study contributes to improve knowledge about the cognitive profile of the different MS phenotypes and understand the cognitive characteristics of Portuguese patients.

Relations among motivation, behaviour, and performance in writing: A multiple-group structural equation modeling study.

BACKGROUND: Writing is a particularly demanding activity, which poses unique motivational challenges for students. Despite the wealth of research on the relation between writing motivation and writing performance, little is known about the role of students' writing frequency in writing motivation and writing performance. AIMS: We aimed to: (1) examine structural relations among two motivational variables (i.e., self-efficacy and attitudes), a behavioural variable (i.e., writing frequency), and writing performance; and (2) inspect whether these relations varied across two text genres (i.e., narrative and opinion texts) and across two educational levels (i.e., students in grades 5-6 and grades 7-8). SAMPLE: Six hundred and five students from grades 5-8 participated in this study. METHODS: Students completed self-report scales and wrote narrative and opinion texts. We conducted multiple-group structural equation modeling to analyse the data. RESULTS: Regarding narrative texts, digital writing frequency was significantly associated with text quality for students in grades 7-8, but this relation was not significant in students from grades 5-6. Both attitudes and self-efficacy for self-regulation made a direct contribution to narrative text quality across educational levels. In addition, attitudes were associated with both literary and digital writing frequency across educational levels. Concerning opinion texts, no significant differences emerged in terms of educational level. Attitudes contributed to both literary and digital writing frequency as well as to opinion text quality across educational levels. CONCLUSIONS: This study underlines the fundamental contribution of motivational variables to students' writing performance. Accordingly, teachers need to adopt motivation-enhancing practices in writing instruction across grade levels.

Real-Time Psychophysiological and Writing Correlates of Expressive Writing.

Concealing memories and emotions associated with a traumatic event seems to have negative effects on health. Re-enacting those events through writing is an opportunity to disclose such memories and emotions, and especially for emotion regulation. To study this, 57 university students were randomly assigned to one of two groups. They either completed an expressive writing or a neutral writing task. Real-time writing and psychophysiological data were recorded throughout the experiment to examine writing dynamics associated with emotion regulation and its psychophysiological correlates (electrodermal activity and electrocardiography measures). The results showed that the expressive group (EG) paused for longer than the control group (CG) denoting a positive and medium effect size ( η p 2 = .10 ) . Furthermore, during and after writing, the EG showed a higher low frequency/high frequency ratio than the CG, evidencing a positive and large effect size ( η p 2 = .22 ) . These real-time findings are interpreted as signs of emotion regulation happening during writing.

Attention, inhibitory control and early mathematical skills in preschool students.

BACKGROUND: Early mathematical skills may be important indicators of school success. Executive Functions (EFs) such as attention and inhibitory control may be related to the development of early mathematical skills. METHOD: This study is aimed at understanding the relationship between two EFs (attention and inhibitory control) and low and high relational and numerical mathematical skills in preschool students (143 children between 4 and 6 years old). Participants completed the Early Numeracy Test Revised and a continuous performance test which assessed attention (omissions and response time [RT]) and inhibitory control (commissions and variability). RESULTS: Logistic Binomial Regression Analysis was carried out showing that in 4 to 6-year olds there are differences in omissions, RT and variability between the groups (low and high relational and numerical mathematical skills). However, once the effect of the age was controlled for, only RT predicted numerical mathematical skills. CONCLUSIONS: The results highlight the importance of attention in the numerical skills of preschool students, with a greater weight of response time which is better in students with higher numerical mathematics skills.

Parents' Perceptions of Student Academic Motivation During the COVID-19 Lockdown: A Cross-Country Comparison.

The COVID-19 outbreak has ravaged all societal domains, including education. Home confinement, school closures, and distance learning impacted students, teachers, and parents' lives worldwide. In this study, we aimed to examine the impact of COVID-19-related restrictions on Italian and Portuguese students' academic motivation as well as investigate the possible buffering role of extracurricular activities. Following a retrospective pretest-posttest design, 567 parents (n Italy = 173, n Portugal = 394) reported on their children's academic motivation and participation in extracurricular activities (grades 1 to 9). We used a multi-group latent change score model to compare Italian and Portuguese students': (1) pre-COVID mean motivation scores; (2) rate of change in motivation; (3) individual variation in the rate of change in motivation; and (4) dependence of the rate of change on initial motivation scores. Estimates of latent change score models showed a decrease in students' motivation both in Italy and in Portugal, although more pronounced in Italian students. Results also indicated that the decrease in students' participation in extracurricular activities was associated with changes in academic motivation (i.e., students with a lower decrease in participation in extracurricular activities had also a lower decrease in motivation). Furthermore, students' age was significantly associated with changes in motivation (i.e., older students had lower decrease). No significant associations were found for students' gender nor for parents' education. This study provides an important contribution to the study of students' academic motivation during home confinement, school closures, and distance learning as restrictive measures adopted to contain a worldwide health emergency. We contend that teachers need to adopt motivation-enhancing practices as means to prevent the decline in academic motivation during exceptional situations.

Effects of planning strategies on writing dynamics and final texts.

Expert writing involves the interaction among three cognitively demanding processes: planning, translating, and revising. To manage the cognitive load brought on by these processes, writers frequently use strategies. Here, we examined the effects of planning strategies on writing dynamics and final texts. Before writing an argumentative text with the triple-task technique, 63 undergraduates were asked either to elaborate an outline with the argumentative structure embedded (structure-based planning condition), to provide a written list of ideas for the text (list-based planning condition), or to do a non-writing-related filler task (no planning condition). Planning showed no effects on the length of the pre-writing pause and cognitive effort, but influenced writing processes occurrences. Compared to participants in the no-planning condition, those in the planning conditions showed a later activation of revising. Moreover, participants in the structure-based condition were mainly focused on translating in the beginning and middle of composition, whereas their peers tended to distribute their attention among all processes. Planning ahead of writing also resulted in texts with longer words, produced at a higher rate. Only the structure-based planning strategy led to an increase in the number of argumentation elements as well as in essays' persuasiveness and overall quality. There was, however, no indication that these improvements in final texts were associated with changes in the dynamics of writing. Overall, the use of structure-based plans seems to be an effective and efficient way of improving undergraduates' argumentative writing.

Timed written picture naming in 14 European languages.

We describe the Multilanguage Written Picture Naming Dataset. This gives trial-level data and time and agreement norms for written naming of the 260 pictures of everyday objects that compose the colorized Snodgrass and Vanderwart picture set (Rossion & Pourtois in Perception, 33, 217-236, 2004). Adult participants gave keyboarded responses in their first language under controlled experimental conditions (N = 1,274, with subsamples responding in Bulgarian, Dutch, English, Finnish, French, German, Greek, Icelandic, Italian, Norwegian, Portuguese, Russian, Spanish, and Swedish). We measured the time to initiate a response (RT) and interkeypress intervals, and calculated measures of name and spelling agreement. There was a tendency across all languages for quicker RTs to pictures with higher familiarity, image agreement, and name frequency, and with higher name agreement. Effects of spelling agreement and effects on output rates after writing onset were present in some, but not all, languages. Written naming therefore shows name retrieval effects that are similar to those found in speech, but our findings suggest the need for cross-language comparisons as we seek to understand the orthographic retrieval and/or assembly processes that are specific to written output.

Tailoring Multicomponent Writing Interventions: Effects of Coupling Self-Regulation and Transcription Training.

Writing proficiency is heavily based on acquisition and development of self-regulation and transcription skills. The present study examined the effects of combining transcription training with a self-regulation intervention (self-regulated strategy development [SRSD]) in Grade 2 (ages 7-8). Forty-three students receiving self-regulation plus transcription (SRSD+TR) intervention were compared with 37 students receiving a self-regulation only (SRSD only) intervention and 39 students receiving the standard language arts curriculum. Compared with control instruction, SRSD instruction-with or without transcription training-resulted in more complex plans; longer, better, and more complete stories; and the effects transferred to story written recall. Transcription training produced an incremental effect on students' composing skills. In particular, the SRSD+TR intervention increased handwriting fluency, spelling accuracy for inconsistent words, planning and story completeness, writing fluency, clause length, and burst length. Compared with the SRSD-only intervention, the SRSD+TR intervention was particularly effective in raising the writing quality of poorer writers. This pattern of findings suggests that students benefit from writing instruction coupling self-regulation and transcription training from very early on. This seems to be a promising instructional approach not only to ameliorate all students' writing ability and prevent future writing problems but also to minimize struggling writers' difficulties and support them in mastering writing.

Implicit theories of writing and their impact on students' response to a SRSD intervention.

BACKGROUND: In the field of intelligence research, it has been shown that some people conceive intelligence as a fixed trait that cannot be changed (entity beliefs), whereas others conceive it as a malleable trait that can be developed (incremental beliefs). What about writing? Do people hold similar implicit theories about the nature of their writing ability? Furthermore, are these beliefs likely to influence students' response to a writing intervention? AIMS: We aimed to develop a scale to measure students' implicit theories of writing (pilot study) and to test whether these beliefs influence strategy-instruction effectiveness (intervention study). SAMPLE: In the pilot and intervention studies participated, respectively, 128 and 192 students (Grades 5-6). METHOD: Based on existing instruments that measure self-theories of intelligence, we developed the Implicit Theories of Writing (ITW) scale that was tested with the pilot sample. In the intervention study, 109 students received planning instruction based on the self-regulated strategy development model, whereas 83 students received standard writing instruction. Students were evaluated before, in the middle, and after instruction. RESULTS: ITW's validity was supported by piloting results and their successful cross-validation in the intervention study. In this, intervention students wrote longer and better texts than control students. Moreover, latent growth curve modelling showed that the more the intervention students conceived writing as a malleable skill, the more the quality of their texts improved. CONCLUSION: This research is of educational relevance because it provides a measure to evaluate students' implicit theories of writing and shows their impact on response to intervention.

Children's high-level writing skills: development of planning and revising and their contribution to writing quality.

BACKGROUND: It is well established that the activity of producing a text is a complex one involving three main cognitive processes: Planning, translating, and revising. Although these processes are crucial in skilled writing, beginning and developing writers seem to struggle with them, mainly with planning and revising. AIMS: To trace the development of the high-level writing processes of planning and revising, from Grades 4 to 9, and to examine whether these skills predict writing quality in younger and older students (Grades 4-6 vs. 7-9), after controlling for gender, school achievement, age, handwriting fluency, spelling, and text structure. SAMPLE: Participants were 381 students from Grades 4 to 9 (age 9-15). METHOD: Students were asked to plan and write a story and to revise another story by detecting and correcting mechanical and substantive errors. RESULTS: From Grades 4 to 9, we found a growing trend in students' ability to plan and revise despite the observed decreases and stationary periods from Grades 4 to 5 and 6 to 7. Moreover, whereas younger students' planning and revising skills made no contribution to the quality of their writing, in older students, these high-level skills contributed to writing quality above and beyond control predictors. CONCLUSION: The findings of this study seem to indicate that besides the increase in planning and revising, these skills are not fully operational in school-age children. Indeed, given the contribution of these high-level skills to older students' writing, supplementary instruction and practice should be provided from early on.
