Reduced Stroop interference for opponent colors may be due to input factors: evidence from individual differences and a neural network simulation

Sensory or input factors can influence the strength of interference in the classic Stroop color-word task. Specifically, in a single-trial computerized version of the Stroop task, when color-word pairs were incongruent, opponent color pairs (e.g., the word BLUE in yellow) showed reduced Stroop interference compared with nonopponent color pairs (e.g., BLUE in red). In addition, participants' color discrimination ability was measured by standard color vision tests (i.e., Farnsworth-Munsell 100-Hue Test and Ishihara plates). Error rates in the Farnsworth-Munsell test correlated positively with the amount of Stroop interference. Neural network simulations (variants of J. D. Cohen, K. Dunbar, & J. L. McClelland's, 1990, model) showed that only a distributed trichromatic input layer was able to simulate these findings. Thus, sensory input from the color system needs to be incorporated into current accounts of the Stroop effect.     

Communicative skills in relation to gender, birth order, childcare and socioeconomic status in 18-month-old children

Variation in communicative skills, defined as gestures, vocabulary comprehension and vocabulary production, was examined as a function of gender, birth order, childcare and socioeconomic status (SES) in 1,019 18-month-old children. The children were recruited at their regular check-up at a number of randomly selected Child Health Care centers in a Swedish county. The participation rate was 88%. The children were assessed by their mothers using a short version of the Swedish Early Communicative Development Inventories. The results demonstrate significant effects of gender and birth order on vocabulary comprehension and vocabulary production. Girls scored higher than boys and first-born children scored higher than later-born children. Type of childcare (family care, care at home and day-care centers) interacted with gender and birth order on vocabulary production and indicated that family care is not as advantageous as care at home or at day-care centers. SES had no effect on children's communicative skills at this age.     

Testing the Work Environment Hypothesis of Bullying on a Group Level of Analysis: Psychosocial Factors as Precursors of Observed Workplace Bullying

The present paper scrutinises the work environment hypothesis of bullying by examining relationships between psychosocial factors at work and bullying within departments on a group level of analysis, as compared to the many studies executed on an individual level of analysis. Relationships between quantitative demands, job control, role demands, leadership behaviour and social climate, and observed bullying were studied in a convenience sample consisting of 276 departments with a total of 4,064 respondents. Between‐group bivariate correlations showed relatively strong relationships (r > .52) between the predictors social climate, leadership behaviour, and role demands, respectively, and observed bullying in the department. A two‐factor higher‐level model was formulated for the independent variables yielding two latent factors reflecting an interpersonal domain and a task‐oriented domain, where the former was strongly associated with observed bullying at a group level of analysis (Beta =?.73), while the last factor yielded an insignificant contribution. The results confirm that a poor social work environment exists within departments in which bullying takes place, hence, yielding further support to the work environment hypothesis. In line with the present results, future studies on workplace bullying should include a group level of analysis.     

The role of prevention focus under stereotype threat: Initial cognitive mobilization is followed by depletion

Previous research has demonstrated that stereotype threat induces a prevention focus and impairs central executive functions. The present research examines how these 2 consequences of stereotype threat are related. The authors argue that the prevention focus is responsible for the effects of stereotype threat on executive functions and cognitive performance. However, because the prevention focus is adapted to deal with threatening situations, the authors propose that it also leads to some beneficial responses to stereotype threat. Specifically, because stereotype threat signals a high risk of failure, a prevention focus initiates immediate recruitment of cognitive control resources. The authors further argue that this response initially facilitates cognitive performance but that the additional cognitive demands associated with working under threat lead to cognitive depletion over time. Study 1 demonstrates that stereotype threat (vs. control) facilitates immediate cognitive control capacity during a stereotype-relevant task. Study 2 experimentally demonstrates the process by showing that stereotype threat (vs. control) facilitates cognitive control as a default, as well as when a prevention focus has been experimentally induced, but not when a promotion focus has been induced. Study 3 shows that stereotype threat facilitates initial math performance under a prevention focus, whereas no effect is found under a promotion focus. Consistent with previous research, however, stereotype threat impaired math performance over time under a prevention focus, but not under a promotion focus.     

Regulatory competence and social communication in term and preterm infants at 12 months corrected age. Results from a randomized controlled trial

Temperamental regulatory competence and social communication in term and preterm infants at 12 months corrected age was studied in a randomized controlled intervention trial aimed at enhancing maternal sensitive responsiveness. Surviving infants <2000 g from a geographically defined area were randomized to an intervention (71) or a control group (69), and compared with term infants (74). The intervention was a modified version of the "Mother-Infant Transaction Program". Regulatory competence was measured with the Infant Behavior Questionnaire, and social communication with the Early Social Communication Scales. Preterm intervention infants with low regulatory competence had higher responding to joint attention than preterm control infants. A sensitizing intervention may moderate the association between temperament and social communication, and thus allow an alternative functional outlet for preterm infants low in regulatory competence. The finding may have implications for conceptualizations of the role of early sensitizing interventions in promoting important developmental outcomes for premature infants.     

How do people with cognitive functional limitations post-stroke manage the use of buses in local public transport?

People with cognitive functional limitations (CFLs) have rarely been the focus of research dealing with road users and their needs. The aim of the present study was to describe how people with CFL post-stroke manage in their use of buses in the framework of their outdoor mobility, and to find out what difficulties, but also what opportunities, they experienced when moving from origin to destination using buses in public transport. Semi-structured interviews combined with participant observations during bus trips with eight persons were performed. Several barriers that have the potential to restrict autonomous outdoor mobility were identified. These barriers were not only represented by well-known infrastructure problems (high pavement curbs, etc.) or ergonomic shortcomings in the buses but, even more so, by specific issues relevant for persons with CFL, e.g. having to cross a road on their way to the bus stop, which poses problems of interaction with fast-moving car traffic. Obtaining all the necessary information prior to and during the trip is difficult and produces insecurity. Often, communication with the bus drivers, not least in connection with the search for information, causes extra stress. Lack of self-confidence and feelings of inferiority add to these problems. Measures to control vehicle speeds, to optimise the communication style of bus drivers with their customers, and to improve customers’ access to information are recommended. Training measures to reassure persons with CFL in connection with their use of the public space are suggested.     

Early communicative gestures and play as predictors of language development in children born with and without family risk for dyslexia

The present study investigated early communicative gestures, play, and language skills in children born with family risk for dyslexia (FR) and a control group of children without this inheritable risk at ages 12, 15, 18, and 24 months. Participants were drawn from the Tromsø Longitudinal study of Dyslexia (TLD) which follows children's cognitive and language development from age 12 months through Grade 2 in order to identify early markers of developmental dyslexia. Results showed that symbolic play and parent reported play at age 12 months and communicative gestures at age 15 months explained 61% of the variance in productive language at 24 months in the FR group. These early nonlinguistic measures seem to be potentially interesting markers of later language development in children born at risk for dyslexia.     

Long Sickness Absence Differences Between Natives and Immigrant Workers: The Role of Differences in Self-reported Health

The limited empirical evidence on sickness absence among immigrants indicates that non-Western immigrants have a higher incidence of sickness-related absence than natives. The purpose of this article is to examine whether health is a contributing factor to the immigrant-native sickness absence gap. The present article makes use of two data sources: register data (FD-trygd) with labour market and long-term sickness absence information linked to a cross-section questionnaire survey on health: The Oslo Health Study, which was conducted in 2000–2001 (N?=?14,114). The findings in this article show that non-Western immigrants have a higher incidence of long-term sickness absence than natives. For both women and men, the differences in long-term sickness absence between non-Western immigrants and natives can be explained by poorer self-reported health among immigrants.     

Workaholism and work–family spillover in a cross-occupational sample

This study examined the relationship between three components of workaholism (work involvement, drive, enjoyment of work) and work–family spillover. A cross-occupational sample consisting of 661 Norwegian employees from six different organizations responded to a Web-based questionnaire measuring workaholism and work–family spillover. A short and revised version of the WorkBAT showed that work involvement was positively related to both positive family-to-work spillover and to negative work-to-family spillover. Drive was positively related to both negative work-to-family and negative family-to-work spillover, and negatively related to positive work-to-family spillover. Enjoyment of work was positively associated with positive work-to-family and positive family-to-work spillover. Workaholism is clearly related to spillover. The findings imply that interventions for workers scoring high on work involvement and drive should be emphasized as these dimensions were associated with negative spillover. More research on this area is warranted.
