Arctic cognition: a study of cognitive performance in summer and winter at 69°N

Evidence has accumulated over the past 15 years that affect in humans is cyclical. In winter there is a tendency to depression, with remission in summer, and this effect is stronger at higher latitudes. In order to determine whether human cognition is similarly rhythmical, this study investigated the cognitive processes of 100 participants living at 69°N. Participants were tested in summer and winter on a range of cognitive tasks, including verbal memory, attention and simple reaction time tasks. The seasonally counterbalanced design and the very northerly latitude of this study provide optimal conditions for detecting impaired cognitive performance in winter, and the conclusion is negative: of five tasks with seasonal effects, four had disadvantages in summer. Like the menstrual cycle, the circannual cycle appears to influence mood but not cognition. Copyright © 1999 John Wiley & Sons, Ltd.     

A developmental study of the influence of task characteristics on motor overflow

Motor overflow refers to involuntary movement or muscle activity that may coincide with voluntary movement. This study examined factors influencing motor overflow in 17 children (8-11 years), and 17 adults (18-35 years). Participants performed a finger pressing task by exerting either 33% or 66% of their maximal force output using their dominant or non-dominant hand. Attention was manipulated by tactile stimulation to one or both hands. Overflow relative to the target force was greater in children compared to adults, and at the lower target force for both groups, but was not influenced by attentional stimulation. Childhood overflow was greater when the left-hand performed the task. Although an immature motor system may underlie an inability to suppress involuntary movement, childhood overflow may provide motor stabilization.     

‘Who would take whose name?’ Accounts of naming practices in same‐sex relationships

The practice of a woman assuming her husband's last name upon marriage is a deeply embedded norm in some countries. Whether or not individual heterosexual couples reproduce or resist this practice, it provides a context for making decisions about marital names. No conventions, other than heteronormative ones, govern naming practices in same‐sex relationships and families, but very little is known about name changing in these contexts. This paper reports an exploratory qualitative study of the ways in which 30 lesbians and gay men in committed relationships made meaning of name changing and keeping. Only one participant reported changing her last name, some considered name changing a future possibility, but most had no plans to change their name. The lack of conventions regarding naming in same‐sex families created a dilemma for some participants—who would take whose name? Many participants did not want to entirely give up their name, thus a hyphenated last name was the most popular option for those contemplating a name change. Accounts of name changing centred on doing/being family. This was also a theme in accounts of name keeping, along with maintaining a continuity of personal and professional identity, avoiding hassle, complications and confusion and resisting heteronormativity. The findings are discussed in relation to other research on naming in same‐sex families and research on heterosexual marital naming practices. Copyright © 2008 John Wiley & Sons, Ltd.     

Fear and perceived uncontrollability of emotion: Evaluating the unique contribution of emotion appraisal variables to prediction of worry and generalised anxiety disorder

Novel theoretical frameworks place the symptom profile of generalised anxiety disorder (GAD) within the context of dysfunctional emotional processes. It is suggested that fear and intolerance of emotions exacerbate subjective distress and motivate the use of maladaptive coping strategies, such as worry. To date, studies evaluating these models have suffered two key limitations. Firstly, few studies have involved treatment-seeking samples, and secondly, none have evaluated the unique variance attributable to emotion appraisal variables above and beyond previously established predictors of worry and GAD. The present study begins to address these limitations by assessing the contribution of fear and perceived uncontrollability of emotions in predicting worry and clinical GAD status after controlling for variance attributable to depressive symptoms, meta-cognitive beliefs, intolerance of uncertainty, and perceptions of external threat. Supporting current models, results showed that perceived control over emotional reactions was a unique predictor of GAD diagnostic status and both clinical and non-clinical worry.     

Predicting People’s Intention to Donate Their Body to Medical Science and Research

Predictors of people’s intention to register with a body bequest program for donating their deceased body to medical science and research were examined using standard theory of planned behavior (TPB) predictors (attitude, subjective norm, perceived behavioral control) and adding moral norm, altruism, and knowledge. Australian students (N = 221) at a university with a recently established body bequest program completed measures of the TPB’s underlying beliefs (behavioral, normative, and control beliefs) and standard and extended TPB predictors, with a sub-sample reporting their registration-related behavior 2 months later. The standard TPB accounted for 43.6%, and the extended predictors an additional 15.1% of variance in intention. The significant predictors were attitude, subjective norm, and moral norm, partially supporting an extended TPB in understanding people’s body donation intentions. Further, important underlying beliefs can inform strategies to target prospective donors.     

A Measure of Delay Discounting Within the Academic Domain

It is important to better understand the decision‐making processes involved in student procrastination, in order to develop interventions that reduce this common problem. Students may procrastinate because studying produces delayed reinforcers; however, no task measuring delay discounting of academic outcomes currently exists. In Experiment 1, we developed and piloted a measure of academic discounting modeled on titrating‐amount tasks successfully used in the discounting literature. Participants made hypothetical choices between working for money (the smaller, sooner reinforcer) and working on an assignment that was due at various times (the larger, later reinforcer). Participants showed systematic decreases in the subjective value of the assignment as a function of delay, and the hyperbolic and hyperboloid models described the shape of this decrease in value well. In general, larger delayed rewards are discounted less steeply than smaller delayed rewards (the magnitude effect). In Experiment 2, we observed the magnitude effect in academic discounting: Participants discounted a “not important” assignment more steeply than an “important” assignment. In the hyperboloid model, this change was captured by an increase in the s parameter. Results provide support for the validity of the academic discounting task.

Relative or absolute? Implications and consequences of the measures adopted to investigate motor overflow

Motor overflow is involuntary overt movement or covert muscle activity that cooccurs with voluntary movement. Overflow is present in several pathological conditions, as well as in neurologically healthy children and older adults, and can be induced in healthy young adults under effortful conditions. This motor phenomenon may provide insight into the underlying mechanisms and kinetic characteristics of voluntary and involuntary motor control in various populations. Although often measured behaviorally using force transduction techniques, different methods of calculating and presenting such overflow data have resulted in seemingly contradictory findings, with limited discussion of the advantages and limitations of different approaches. In this article, the authors examined the relevant literature to highlight significant methodological considerations for authors and readers conducting or appraising this type of research. Issues regarding the interpretation and reporting of findings are also discussed. Researchers are encouraged to continue using behavioral measures to create well-defined variables that enable the study of the kinematic characteristics of overflow, as these may offer promising new ways forward in better characterizing and understanding this intriguing movement phenomenon.     

Life Design Career Counselling with an Abandoned Adolescent: A Case Study

This article describes the value of life design counselling with an abandoned adolescent female. The participant was selected purposively from among a group of abandoned adolescent females who had expressed a need for career counselling. The life intervention comprised two 90-minute sessions per week over a period of a month. Life design data included collage, family constellation, life line, career style interview, asset map and life chapters. Following the intervention, the participant demonstrated career adaptability and an eagerness to take an active part in her evolving life story. Life design counselling has potential to meet the career counselling needs of children with neglect and abandonment experience.     

South African Teachers' Experiences of Children in their Classrooms who may have ADHD

This study focused on understanding and explaining how teachers experience children in their classrooms who may have Attention Deficit Hyperactivity Disorder (ADHD). The study was a qualitative study in which 17 teachers from three different schools in Gauteng, South Africa, were interviewed. Content theme analysis was conducted on the textual data. Findings from the study indicate that (1) the teachers kept children who might have ADHD busy with different activities in order to manage their classrooms more effectively, (2) the teachers believed that children who might have ADHD challenged them, and (3) the teachers believed that they needed to share information with other teachers on how to manage and support children who might have ADHD and also that they needed outside assistance from a specialist. The study points to the complex experiences of teachers who have to deal with children with ADHD in their classrooms and recommends increased collaboration between professionals and teachers.     

How Children Experience the Assets that Support their Learning

The study, on which this article is based, explored the ways in which primary school children in an urban (city centre) setting experience the assets and resources that support their learning. The researchers used a qualitative phenomenological research design incorporating an interpretive and constructivist perspective. The study was conducted in a primary school in Tshwane, Gauteng province, South Africa. The participants were eight African female participants in Grades 5–7 who had overcome extrinsic barriers to learning. They participated in a focus group discussion during which the relevant and natural units of significant statements were listed (horizontalisation) and structured into central clusters of meanings. Textural themes (what) and structural themes (how) were identified. The study found that human resource assets were central to the process of connecting a variety of assets that supported learning. The study also found a significant compound effect of assets, for example increased connected assets had a noteworthy additional positive effect on learning support. The identified assets interrelatedly mobilised other assets (textural findings) on one of five levels (structural findings: physical assets, social assets, safety assets, esteem assets and self-actualisation) in various systems and contexts that contribute to learning support. This article elaborates on these findings.
