Sense of community in a remote mining town: Validating a Neighborhood Cohesion scale

Psychometric properties and determinants of Buckner's Neighborhood Cohesion Index (NCI) have previously been reported for 206 individuals from three Washington, DC suburbs. This study analyses the properties and determinants of the scale for 1182 mine workers in Elliot Lake, a remote Canadian single-industry town. Data were collected through in-person interviews. The scale in the Elliot Lake sample was highly reliable (α=.91) and the Elliot Lake and Washington NCI item-total scale correlations were similar. Multiple regression found income and education related significantly negatively and years in neighborhood and home ownership significantly positively to NCI with coefficients comparable to those Buckner found in Washington. However, additional significant positive predictors of NCI were home equity, length of home ownership, and the presence of both pre-school-age and school-age children in the home, whereas a significant negative predictor was poor health. The NCI thus appears to be stable across societies, and shows systematic relationships with background variables. Home equity, duration of home ownership, children and health were significant predictors of NCI in our larger Canadian sample. This paper is based on data from the Elliot Lake Tracking Study. We are eager to acknowledge the contribution of our collaborators, David Leadbeater and Peter Suschnigg, in designing the study and collecting the data. We take full responsibility for our conclusions. Funding for the study has been provided by the Laurentian University Institute for Northern Ontario Research and Development, The Ontario Ministry of Northern Development and Mines, and the Elliot Lake Job Creation Fund.     

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.     

On the adaptive function of children's and adults’ false memories

Recent research has shown that memory illusions can successfully prime both children's and adults' performance on complex, insight-based problems (compound remote associates tasks or CRATs). The current research aimed to clarify the locus of these priming effects. Like before, Deese–Roediger–McDermott (DRM) lists were selected to prime subsequent CRATs such that the critical lures were also the solution words to a subset of the CRATs participants attempted to solve. Unique to the present research, recognition memory tests were used and participants were either primed during the list study phase, during the memory test phase, or both. Across two experiments, primed problems were solved more frequently and significantly faster than unprimed problems. Moreover, when participants were primed during the list study phase, subsequent solution times and rates were considerably superior to those produced by those participants who were simply primed at test. Together, these are the first results to show that false-memory priming during encoding facilitates problem-solving in both children and adults.     

Barriers to Computerized Career Interventions in Community Outreach Centers

This study used a survey design to investigate if computer experience and computer attitudes influence whether economically marginalized individuals desire access to computerized career services in community outreach centers. The majority (84%) of the sample reported a desire for access to computerized career services at community outreach centers. A multiple regression analysis indicated computer attitudes as most predictive of intention to use computerized career services (β = .29, p < .01). Results support extending access to computerized career services in community outreach centers to meet the needs of economically marginalized individuals.     

Family Impact of Tourette's Syndrome

Tourette's syndrome (TS) is a neuropsychological disorder characterized by vocal and motor tics. TS is also associated with several behavior disorders such as Attention Deficit Hyperactivity Disorder, Oppositional Defiant Disorder, conduct disorder, and Obsessive-Compulsive Disorder. We examined the impact of Tourette's syndrome with and without comorbid psychiatric disorders on the family. TS complicated by comorbid disorders had a greater impact on the family than uncomplicated TS. Tourette's symptom severity was significantly correlated with the level of impact on the family and with the number of comorbid disorders. TS is a disorder with effects that extend beyond motor and vocal tics.     

Family assessment: developing a formal assessment system in clinical practice

In a previous paper, we reviewed the literature on family assessment and set out some principles that can be derived from previous work. This paper describes the development of a system for family assessment which uses these principles and then gives a brief account of the practical difficulties encountered in applying such a system. (Empirical data on the system will be presented in subsequent papers as they become available.)     

Eye fixations are influenced by the distribution of information within words

Reader's eye movements were monitored while they inspected isolated words in preparation for a synonym judgement task. The 10-letter words appeared on a screen near the point of fixation, with the first fixation being imposed near the beginning, or the centre, or the ending of the word. The words themselves had uneven distributions of information, in that the beginnings or the endings contained common sequences of letters in English. Three types of words were used: those with very redundant endings (e.g., yearningly), with moderately redundant endings (e.g., varnishing), and with moderately redundant beginnings (e.g., contravene). Redundancy was defined in terms of the total number of words in English which possess that particular sequence of five letters as the beginning or the ending. The experiments asked whether the convenient viewing location within a word varied according to the distribution of information, and whether the extent of redundancy in a word ending is reflected in the distribution of visual attention given to the word. The results were analysed separately for those cases where the reader made just two fixations upon the word before moving to the synonym task, and for those cases where the reader made exactly three fixations. These were the dominant fixation patterns. Evidence for the notion of a convenient viewing position consisted of long first fixations (when there were just two fixations), when this fixation was near the centre of the word. The distribution of information within the words did not influence the duration of the first fixation, although the duration of the gaze within each half-word did increase when more informative letter sequences were being inspected. The extent of redundancy was also seen to influence the inspection patterns, when a comparison was made between the two types of words with redundant endings. Words with very redundant endings received fewer fixations when the first fixation was at the beginning, and for words gaining exactly two fixations, the second fixation was shorter if the word had a very redundant ending.     

The effect of sleep deprivation on signal detection parameters

Twelve subjects performed a high signal rate vigilance task, once after a night's sleep, and once after a night without sleep. Raw scores were transformed into the signal detection parameters, d' and β. After sleep deprivation, detection performance was significantly impaired. This was reflected in a fall of d', whereas β was not significantly altered. Analysing the control data alone for comparison with other vigilance studies revealed a decrement in % signals detected and d', and an increase in β from the first to the second half of the test.
