Fatigue following Paediatric Acquired Brain Injury and its Impact on Functional Outcomes: A Systematic Review

Fatigue is a commonly reported sequela following an acquired brain injury (ABI), and can have a negative impact on many areas of a child’s life. However, there is minimal research that focuses on fatigue specifically, and so factors such as its occurrence, duration, and impact on functioning remain uncertain. This systematic review aims to provide a comprehensive summary of the research to date, bringing together a number of studies with a focus on paediatric ABI and fatigue. Terms were searched in relevant databases (PsycInfo, Medline, CINAHL), and articles were included or excluded based on specified criteria. Of the 1177 papers identified in the original search, a total of 9 papers met inclusion criteria, and were categorised as traumatic brain injury (TBI; n?=?4), meningitis and meningococcal disease (n?=?2), brain tumours (n?=?2), and mixed ABI group (n?=?1). Key findings suggest that fatigue is a problem encountered by a significant proportion of patients in all the studies reviewed, and often occurred regardless of the cause; fatigue was also associated with poor academic achievement, limited physical activity, and social and emotional problems. Injuries of greater severity were associated with higher levels of fatigue and worse outcomes. Several management options were suggested, though their efficacy was not reported. Future research is required with a suggested focus on using multiple time points to better understand the trajectories of fatigue following childhood ABI, and to build an evidence base to determine which management options are most suitable.     

The University of South Florida free association, rhyme, and word fragment norms.

Preexisting word knowledge is accessed in many cognitive tasks, and this article offers a means for indexing this knowledge so that it can be manipulated or controlled. We offer free association data for 72,000 word pairs, along with over a million entries of related data, such as forward and backward strength, number of competing associates, and printed frequency. A separate file contains the 5,019 normed words, their statistics, and thousands of independently normed rhyme, stem, and fragment cues. Other files provide n x n associative networks for more than 4,000 words and a list of idiosyncratic responses for each normed word. The database will be useful for investigators interested in cuing, priming, recognition, network theory, linguistics, and implicit testing applications. They also will be useful for evaluating the predictive value of free association probabilities as compared with other measures, such as similarity ratings and co-occurrence norms. Of several procedures for measuring preexisting strength between two words, the best remains to be determined. The norms may be downloaded from www.psychonomic.org/archive/.     

Validation of a reflective practice rubric for evaluating the complexity of teacher candidate digital and written reflections

This study was conducted to validate the effectiveness of a previously published rubric for evaluating the reflective characteristics contained within reflective artifacts. The goal of the study was to test the validity of the rubric when evaluating written reflection and digital artifacts of teacher candidates. The theory of reflection is discussed, and the process of eliciting higher levels of reflection through various modalities from written prompts. Secondly, this study describes the process participants followed while learning to use the rubric, the methods of evaluating artifacts using the rubric, and the results the study produced. The rubric proved to be an effective tool when determining the level of reflection, a teacher candidate demonstrated. Lastly, this article discusses limitations of the rubric, as well as suggestions for further research regarding teaching reflective practices, and how to refine one’s own reflective skills to achieve a level of deep reflection on/for action.     

THE EFFECTS OF NARRATIVE AND EXPOSITORY ORGANIZATIONAL INSTRUCTION ON SIXTH‐GRADE CHILDREN'S COMPREHENSION OF EXPOSITORY AND NARRATIVE PROSE

Fifty‐six sixth‐grade students were randomly assigned to four instructional groups. These groups were defined by crossing two levels of instruction, organizational and traditional, with two levels of text type, expository and narrative. After four days of instruction the members of each group were randomly assigned to the eight testing conditions which were defined by three factors, instruction (organizational, traditional), text type (narrative or expository), organization (intact, scrambled). Students read passages, answered multiple choice questions, and wrote summaries of the passage. Results indicated that the students who received the organizational instruction wrote better summaries than students who received traditional instruction.     

The effects of surface detail on object categorization and naming

Three experiments are reported examining the effects of surface colour and brightness/texture gradients (photographic detail) on object classification and naming. Objects were drawn from classes with either structurally similar or structurally dissimilar exemplars. In Experiment 1a, object naming was facilitated by both congruent surface colour and photographic detail, with the effects of these two variables combining under-additively. In addition incongruent colour disrupted naming accuracy. These effects tended to be larger on objects from structurally similar classes than on objects from structurally dissimilar classes. Experiment 1b examined superordinate classification. There were again advantages due to congruent colour and photographic detail on responses to objects from both structurally similar and structurally dissimilar classes. Incongruent colour disrupted classification accuracy on structurally distinct but not structurally similar items. For structurally similar items, the advantages of congruent surface attributes on classification were smaller than on naming, but this was not the case for structurally dissimilar items. Experiment 2 examined subordinate classification of structurally similar objects. Now effects of congruent and incongruent colour, but not of photographic detail, were found. Experiment 3 showed that congruent and incongruent colour effects occur only when the colours occupy the internal surfaces of objects. The results suggest that surface details can affect object recognition and naming, depending upon: (1) the degree to which objects must be differentiated for a correct response to be made, and (2) the nature of the rate-limiting process determining performance.     

The role of executive function in reading comprehension among beginning readers

Empirical evidence supports the importance of executive function (EF) in reading, but the underlying mechanism through which EF contributes to the reading process is unclear. The present study examined the direct and indirect effects of EF on reading comprehension through the indirect pathway of language and cognitive skills (i.e., syntactic awareness and text-connecting inferencing) among the beginning readers. The sample included one hundred and sixty-five 2^nd and 3^rd grade students. The participants were tested on working memory (visuospatial working memory and verbal working memory) and inhibition (prepotent response inhibition and cognitive inhibition), and their syntactic awareness, inference-making, and reading comprehension. The unitary EF construct was obtained by means of confirmatory factor analysis based on the structure of EF in middle childhood suggested in developmental studies. Structural equation modelling was used to examine the direct and indirect effects of EF on the reading outcome. The findings indicated that EF has a direct effect on reading comprehension among the beginning readers. The indirect pathway showed that EF supports the ability to evaluate on grammatical structure of sentences (i.e., syntactic awareness) during reading. However, the indirect effect of EF on reading via inference-making ability is insignificant. The findings highlight the contributions of EF to reading and provide empirical evidence to the hypothetical relation between EF and language skills suggested in DIER (Kim, 2020, Resarch Quarterly, 50, 459). It further extends our knowledge on the roles of EF in the reading process among the beginning readers. Future research directions are implicated as well.
