Health‐adjusted neuropsychological test norms based on 463 older Swedish car drivers

There is a need for improved normative information in particular for older persons. The present study provides neuropsychological test norms on seven cognitive tests used in a sample representing the general older driving population, when uncontrolled and controlled for physical health. A group of 463 healthy Swedish car drivers, aged 65 to 84 years, participated in a medical and neuropsychological examination. The latter included tests of visual scanning, mental shifting, visual spatial function, memory, reaction time, selective attention, and simultaneous capacity. Hierarchical regression analyses demonstrated that, when uncontrolled for health, old age was associated with significant impairment on all seven tests. Education was associated with a significant advantage for all tests except most reaction time subtests. Women outperformed men on selective attention. Controlling for health did not consistently change the associations with education, but generally weakened those with age, indicating rises in normative scores of up to 0.36 SD (residual). In terms of variance explained, impaired health predicted on average 2.5%, age 2.9%, education 2.1% and gender 0.1%. It was concluded (1) that individual regression‐based predictions of expected values have the advantage of allowing control for the impact of health on normative scores in addition to the adjustment for various demographic and performance‐related variables and (2) that health‐adjusted norms have the potential to classify functional status more accurately, to the extent that these norms diverge from norms uncontrolled for physical health.

Parents' description of conduct problems in their children - a test of the Eyberg Child Behavior Inventory (ECBI) in a Swedish sample aged 3-10

The Eyberg Child Behavior Inventory (ECBI) is a widely used 36-item uni-dimensional parent rating scale constructed to measure disruptive behavior problems in children. However, in an American sample a 22-item version, including three subscales, has been suggested in order to increase the usefulness of the ECBI. Two studies were conducted to test the ECBI in a Swedish sample (N = 841). The aims of Study I were (a) examine the psychometric properties of the ECBI (b) to investigate the correspondence between mothers' and fathers' ratings, and (c) to obtain Swedish norms. The aim of Study II was to test the suggested three-factor solution in the Swedish sample using a confirmatory factor analysis (CFA). The ECBI showed good psychometric properties also in the present study, and Swedish normative data is presented. The best-fitting CFA-model was identical to the previously suggested three-factor model, which thus might be a useful alternative to the 36-item version.     

Empathy or Intersubjectivity? Understanding the Origins of Morality in Young Children’

This article is about young children’s morality and their concern for others’ wellbeing. Questions of what the value of others’ wellbeing can signify, how this value becomes visible to children and how it is expressed in their interaction will be posed. In this analysis, children’s commitment to others’ wellbeing is discussed in terms of two theories, namely the philosopher Maurice Merleau-Ponty’s (1962, 1964) theory of intersubjectivity and the psychologist Martin Hoffman’s (1984, 1987, 2000) theory of empathy. The interaction between children and adults in pre-school, drawn from different studies of morality (Johansson, 1999, 2001, 2002, 2003), constitutes the empirical basis. In the discussion, it is claimed that children’s care for others’ wellbeing can be understood in a fruitful way as experiences of, approaches to and ways of being involved in the other’s life-world rather than as expressions of empathy.

Cross-cultural comparison of motivation to learn in physical education: Japanese vs Swedish schoolchildren

The present study compared differences between Japanese and Swedish schoolchildren in learning motivation-related variables in physical education. The subjects were 1,562 Japanese fifth and sixth graders (776 boys and 786 girls) ranging in age from 10 to 12 years and 573 Swedish fifth graders (306 boys and 267 girls) from 10 to 13 years (M = 11.4, SD = 0.5). They completed three questionnaires to evaluate the children's learning motivation, factors supporting motivation to learn, and preferences of learning behavior. The questionnaires were taken from Nishida's Diagnosis of Learning Motivation in Physical Education Test, a multidimensional and comprehensive test that measures learning motivation. A 2 x 2 (country by sex) multivariate analysis of variance indicated both Swedish boys and girls scored significantly higher than the Japanese children on most subscales. Results were discussed in relation to differences in the sports environment and culture of the two countries.     

Internet addiction among Norwegian adults: a stratified probability sample study

Most Norwegians are Internet users. We conducted a stratified probability sample study (Norway, 2007, age-group 16–74 years, N = 3,399, response rate 35.3%, 87.1% Internet users) to assess the prevalence of Internet addiction and at-risk Internet use by the Young Diagnostic Questionnaire (YDQ). The prevalence of Internet addiction (YDQ score 5–8) was 1.0% and an additional 5.2% were at-risk Internet users (YDQ score 3–4). Internet addiction and at-risk Internet use was strongly dependent on gender and age with highest prevalences among young males (16–29 years 4.1% and 19.0%, 30–39 years 3.3% and 10.7%). Logistic regression showed that male gender, young age, university level education, and an unsatisfactory financial situation were factors positively associated with "problematic Internet use" (at-risk and addicted use combined). Time spent on the Internet and prevalence of self-reported sleeping disorders, depression, and other psychological impairments increased linearly with YDQ score. Problematic Internet use clearly affects the lives of many people.     

Combined eyetracking and keystroke-logging methods for studying cognitive processes in text production

Writers typically spend a certain proportion of time looking back over the text that they have written. This is likely to serve a number of different functions, which are currently poorly understood. In this article, we present two systems, ScriptLog+TimeLine and EyeWrite, that adopt different and complementary approaches to exploring this activity by collecting and analyzing combined eye movement and keystroke data from writers composing extended texts. ScriptLog+TimeLine is a system that is based on an existing keystroke-logging program and uses heuristic, pattern-matching methods to identify reading episodes within eye movement data. EyeWrite is an integrated editor and analysis system that permits identification of the words that the writer fixates and their location within the developing text. We demonstrate how the methods instantiated within these systems can be used to make sense of the large amount of data generated by eyetracking and keystroke logging in order to inform understanding of the cognitive processes that underlie written text production.     

Type A behavior and work situation: associations with burnout and work engagement

The aim of the present study was to investigate Type A behavior as well as perceived work situation, and associations with burnout and work engagement. The associations in focus were investigated through hierarchical regressions in a sample (N= 329) of Swedish Information Communication Technology consultants. The findings indicated that both work situation and Type A behavior was correlated with work engagement and burnout; however, no interactions between Type A behavior and work situation were elicited. The main conclusion was that the achievement striving aspect of Type A behavior appears as "non-toxic" and is related only to work engagement. However, the irritability/impatience aspect appears to be responsible for burnout complaints among Type A individuals, possibly through negative effects of the mood itself than through perceived stress at work.     

Sensorimotor prediction and memory in object manipulation.

When people lift objects of different size but equal weight, they initially employ too much force for the large object and too little force for the small object. However, over repeated lifts of the two objects, they learn to suppress the size-weight association used to estimate force requirements and appropriately scale their lifting forces to the true and equal weights of the objects. Thus, sensorimotor memory from previous lifts comes to dominate visual size information in terms of force prediction. Here we ask whether this sensorimotor memory is transient, preserved only long enough to perform the task, or more stable. After completing an initial lift series in which they lifted equally weighted large and small objects in alternation, participants then repeated the lift series after delays of 15 minutes or 24 hours. In both cases, participants retained information about the weights of the objects and used this information to predict the appropriate fingertip forces. This preserved sensorimotor memory suggests that participants acquired internal models of the size-weight stimuli that could be used for later prediction.
