Uptake of Breast Screening is Influenced by Current Religion and Religion of Upbringing

Research has shown that individuals with a current religious affiliation are more likely to use preventive health services. The aim of this study was to determine whether breast screening uptake in Northern Ireland is higher amongst women with a current affiliation to an organised religion and, for those with no current affiliation, to examine whether their religion of upbringing is associated with uptake of breast screening. The Northern Ireland Longitudinal Study (NILS) was used to link Census and national breast screening data for 37,211 women invited for routine breast screening between 2001 and 2004. Current religious affiliation, religion of upbringing and other demographic and socio-economic characteristics were as defined on the Census form. Multivariate logistic regression was used to determine the relationship between religion affiliation and attendance. Uptake of breast screening is about 25% lower for those without a current religious affiliation. There are modest differences between Catholics and Protestants, with the latter about 11% more likely to attend for screening. For those with no current religion, the religion of upbringing appears to positively influence attendance rates. These differences remain after adjustment for all of the socio-demographic and socio-economic factors that have been shown to influence uptake rates of breast screening in the UK to date. Record linkage is an efficient way to examine equity across demographic characteristics that are not routinely available. The lower uptake amongst those with no religious affiliation may mean that screening services may find it difficult to maintain or improve uptake rate in an increasingly secularised society.     

The Internal and External Validity of Sluggish Cognitive Tempo and its Relation with DSM–IV ADHD

Studies of subtypes of DSM-IV attention-deficit/hyperactivity disorder (ADHD) have provided inconsistent support for the discriminant validity of the combined type (ADHD-C) and predominantly inattentive type (ADHD-I). A large sample of children and adolescents with ADHD (N?=?410) and a comparison group without ADHD (N?=?311) were used to test the internal and external validity of sluggish cognitive tempo (SCT), a dimension characterized by low energy and sleepy and sluggish behavior. SCT scores were then incorporated in analyses of ADHD subtypes to test whether the discriminant validity of ADHD-C and ADHD-I could be improved by including SCT symptoms as part of the criteria for ADHD-I. Factor analyses of parent and teacher ratings indicated that six SCT items loaded on a factor separate from symptoms of ADHD and other psychopathology, providing important support for the internal validity of SCT. The external validity of SCT was supported by significant associations between SCT and measures of functional impairment and neuropsychological functioning when symptoms of ADHD and other psychopathology were controlled. However, contrary to initial predictions, high levels of SCT did not identify a subgroup of ADHD-I that was clearly distinct from ADHD-C. Instead, the current results suggest that DSM-IV inattention and SCT are separate but correlated symptom dimensions that are each independently associated with important aspects of functional impairment and neuropsychological functioning.     

Skill in map reading and memory for maps

Studies of expertise have typically shown that experts have better memory for materials from their fields than do novices. However, previous research on memory for maps has not shown the expected effect of expertise. The present study differed from previous studies by using contour maps as well as planimetric maps. In Experiment 1 the expected superiority in memory performance was found for skilled map readers when contour maps were used, but not when planimetric maps were used.

In Experiment 2, the main results of Experiment 1 were replicated, and, in addition, process tracing data were obtained during both study and test phases of contour map learning. Objective measures of attentional and retrieval focussing revealed almost no differences between the skilled and unskilled subjects. However, analyses of verbal protocols showed that the skilled subjects made more use of specialist schemata, whereas the unskilled subjects spent more time in reading place names. During recall, the skilled subjects made more use of both specialist and “lay” schemata, whereas the unskilled retrieved more place-name information.

The results are interpreted in terms of a schema-based approach to expertise.     

Bisection of shapes and lines: analysis of the visual and motor aspects of pseudoneglect

This study examined the visual and motor components of pseudoneglect as expressed on horizontal bisection tasks. Ten participants were tested on bisection of lines and elliptical shapes and judgement of pretransected lines. Results showed the same magnitude of leftward error on all three tasks, in contrast to previous findings for patients with visuospatial neglect who are known to bisect ellipses and circles much more accurately than lines. Participants' mean line bisection error was significantly further to the left than the mean subjective midpoint found on the judgement task. The findings contradict the claim that the visual component of pseudoneglect is caused by the same mechanism that causes visuospatial neglect but support the hypothesis that the motor component of pseudoneglect is similar to directional hypometria.     

Conditions for speeding behaviour: A comparison of car drivers and powered two wheeled riders

Against a UK background of decreases in collisions involving car drivers, motorcycle collisions are on the increase. To throw light on this process, this paper explores differences between motorcyclists and car drivers in the conditions for speeding behaviour. Some predictions derived from the model of Task-difficulty Homeostasis (TDH) were tested using self-report data from samples of older (>35 years), male car drivers (n = 269) and motorcyclists (n = 102). As predicted, riders were more likely to speed on rural roads and less likely to speed on urban roads, and, riders were much more likely to speed in daytime than at night.Riding a motorcycle offers opportunities for expressive use of the vehicle and riders are more likely to say they really enjoy riding fast. However amongst older riders this behaviour appears to be largely confined to daytime riding on rural roads. Compared with cars, motorcycles provide more of an opportunity to manoeuvre around obstacles in controlling task demand, rather than using speed as the primary controlling variable. Although this provides more options for the rider, it carries with it vulnerability to loss of control from variation in road surface adhesion and maintaining too high a speed.     

Effect of a directional cue on line bisection

Normal participants display a leftward bias when bisecting horizontal lines. It has been proposed that bisection errors can be affected by representational biases. We investigated the possibility that this effect could also be explained as the result of perceptual cueing. Participants bisected horizontal lines with identical arrows arranged around the lines, all pointing to the same end. The arrows significantly affected bisection placement, although participants bisected significantly away from the direction the arrows pointed to. The findings favor the hypothesis that cueing, rather than representation, can affect bisection errors.     

Sex differences in smiling as measured in a picture taking task

Previous research suggests females smile more than males in a picture taking task (Mills, 1984; Morse, 1982; Ragan, 1982). Experiment 1 sought to replicate this effect and, in addition, investigate if the gender of the photographer or instructions to smile would influence smiling in females and males. Subjects were told that their picture would be used in a subsequent facial perception study. Results showed that subjects instructed to smile smiled more than subjects given no instructions. There were no main effects for subject's or photographer's gender and no interactions. In Experiment 2, graduating students from the University of New Brunswick, Saint John, completed a questionnaire which assessed how much subjects wanted to smile for their yearbook picture, whether subjects selected a picture of themselves smiling for their yearbook, and how much the photographer encouraged them to smile. Experiment 2 showed that females wished to smile significantly more than males, and females selected a picture of themselves smiling significantly more than males. Males and females did not differ in the reported degree to which the photographer encouraged them to smile. Results from Experiments 1 and 2 suggest that sex differences in smiling as measured in a picture taking task depend critically on the situation in which the picture is taken.
