Can active navigation be as good as driving? A comparison of spatial memory in drivers and backseat drivers

When driving a vehicle, either the driver or a passenger (henceforth: backseat driver) may be responsible for navigation. Research on active navigation, primarily addressed in virtual environments, suggests that controlling navigation is more central for spatial learning than controlling movement. To test this assumption in a real-world scenario, we manipulated movement control through seating participants in the front or the back position of a tandem bike, and navigation control by presenting differently detailed maps to participants unfamiliar (Experiment 1) or familiar (Experiment 2) with an environment. Landmark knowledge was tested with recognition tasks. For participants unfamiliar with the environment (Experiment 1), passive navigation enabled better landmark recognition than active navigation, but there was no effect of movement control. For participants more familiar with the environment (Experiment 2), there was no effect of navigation control, but drivers showed better landmark recognition than backseat drivers. These findings are discussed in relation to action memory research. Measures of route and survey knowledge demonstrated that good performance resulted from active navigation (Experiment 1-2). Moreover, with regard to these measures, driving compensated for passive navigation if the environment was familiar (Experiment 2). An additional experiment in a lab setting (Experiment 3) validated the manipulation of navigation control and the used tasks and demonstrated the importance of real environment exposure. As our findings suggest, driving may be more relevant for remembering landmarks, but actively controlling navigation (even as a backseat driver) is more relevant for remembering a route than maneuvering a vehicle.     

Number processing and calculation in Brazilian children aged 7-12 years

Numerical cognition is based on two components - number processing and calculation. Its development is influenced by biological, cognitive, educational, and cultural factors. The objectives of the present study were to: i) assess number processing and calculation in Brazilian children aged 7-12 years from public schools using the Zareki-R (Battery of neuropsychological tests for number processing and calculation in children, Revised; von Aster & Dellatolas, 2006) in order to obtain normative data for Portuguese speakers; ii) identify how environment, age, and gender influences the development of these mathematical skills; iii) investigate the construct validity of the Zareki-R by the contrast with the Arithmetic subtest of WISC-III. The sample included 172 children, both genders, divided in two groups: urban (N = 119) and rural (N = 53) assessed by the Zareki-R. Rural children presented lower scores in one aspect of number processing; children aged 7-8 years demonstrated an inferior global score than older; boys presented a superior performance in both number processing and calculation. Construct validity of Zareki-R was demonstrated by high to moderate correlations with Arithmetic subtest of WISC-III. The Zareki-R therefore is a suitable instrument to assess the development of mathematical skills, which is influenced by factors such as environment, age, and gender.     

Moderate intensity exercise facilitates working memory

ObjectivesAlthough the effect of exercise on cognitive functioning has received considerable empirical and theoretical attention, the influence of concurrent exercise on complex cognitive function remains poorly understood. Our research was designed to investigate working memory during a bout of dynamic exercise.DesignAn experimental design was used.MethodsIn two experiments, we examined the impact of moderate intensity exercise on performance of a paced auditory serial addition task (Experiment 1, N = 24) and a Sternberg task (Experiment 2, N = 120). The tasks were performed at rest and while cycling at different power outputs.ResultsWe found that moderate intensity exercise increased the number of correct responses at medium-to-fast stimulus presentation rates during the paced auditory serial addition task and lowered the response latency slopes during the Sternberg task.ConclusionsOur findings show that working memory is improved by dynamic exercise at moderate intensities and short duration.     

Preference for Violent Electronic Games and Aggressive Behavior among Children: The Beginning of the Downward Spiral?

A one-year longitudinal study with 324 German third and fourth graders was conducted in order to find out whether a preference for violent electronic games socializes children to become more aggressive or whether aggressive individuals tend to select this type of game. Cross-lagged panel analyses suggest that children who were rated as openly aggressive at Time 1 intensified their preference for violent electronic games over time. We determined that it could be ruled out that this selection effect was due to a number of underlying variables ranging from ecological variables (neighborhood) to family variables (migration status, older brother) and child variables (gender, self-esteem, level of achievement). Discussion focuses on the emerging preference for violent electronic games among children.     

Health-Related Quality of Life is Associated with Positive Affect in Patients with Coronary Heart Disease Entering Cardiac Rehabilitation

Health-related quality of life (QoL) is an important and widely used outcome measure in cardiac populations. We examined the relationship between positive affect and health-related quality of life, controlling for traditional cardiovascular risk factors, clinical variables and negative affect. We further investigated the role of gender in this relationship given the well-known gender differences in cardiovascular health. We enrolled 746 patients with coronary heart disease (CHD) before they entered outpatient cardiac rehabilitation. All patients completed the Global Mood Scale and the SF-36 Health Survey. Positive affect was independently associated with mental (p < .001) and physical QoL (p < .001) after controlling for control variables. Gender moderated the relationship between positive affect and physical QoL (p = .009) but not mental QoL (p = .60). Positive affect was positively associated with physical QoL in men (p < .001) but not in women (p = .44). The health-related QoL of patients with CHD is associated with a person’s level of positive affect.     

Emotional Abuse and Psychosis: A Recent Review of the Literature

This article evaluates the published empirical findings on childhood emotional abuse and its proposed relationship with psychotic symptoms. Research and governmental policy indicates that emotional abuse is present in all forms of abuse and neglect, suggesting it is the form of abuse most frequently linked to mental health problems. Literature searches were conducted in 3 peer-reviewed electronic databases and relevant papers were reviewed. Results suggest childhood emotional abuse is statistically related to psychosis in adulthood. This adds tentative support to the hypothesis that emotional abuse is related to psychotic experiences; in particular to hallucinations and persecutory delusions. A number of studies also provide tentative support to the dose–response effect proposed between cumulative trauma and a greater risk of positive psychotic symptoms.     

“They never listen”: towards a grounded theory of the role played by trusted adults in the spiritual lives of children

This qualitative study addresses the lack of research into the role of trusted adults in the spiritual lives of children. Semi-structured interviews were conducted with nine children from a British primary school and the data analysed using a grounded theory approach. Six categories were identified outlining the reciprocal relationship of unavailability and withholding between children and their trusted adults and how children made sense of spirituality in the absence of explicit guidance. It was found that the children had little opportunity for negotiating a shared understanding or experience of spirituality with adults and, as a result, either preserved an isolated and secret sense of spirituality or accepted what they observed to be their trusted adults' stance. The practical and theoretical implications of the children's responses in the absence of trusted adults are discussed and recommendations are made for practice and future research.     

Aging and Stereotype Suppression

ABSTRACT

Recent work in social cognitive aging has suggested that older adults are more likely than younger adults to activate and use stereotypic information, even when they intend not to. Furthermore, evidence suggests that older adults have difficulty altering their interpretation of a situation, even when it has become clear that their initial interpretation is incorrect. In the current study, younger and older adults read a series of narratives in which a character had a sex-stereotyped occupation (e.g., a plumber is stereotypically male), and the character's gender was either consistent or inconsistent with that stereotype. Explicit labeling of gender was also varied. Results revealed that with explicit labeling, older adults were able to discount their stereotypes and avoid processing difficulties when subsequent stereotype-inconsistent information was encountered. These data suggest that when counter-stereotypic information is explicitly provided at encoding, older adults are no more likely than younger adults to rely on stereotypes, and are similarly capable of altering their interpretation of a situation when information suggests that interpretation is incorrect. These findings indicate that although older adults are more prone to the influence of unwanted stereotypes, this effect can be averted and judgments can be made more egalitarian by providing older adults with explicit stereotype contradiction at encoding.     

Executive Functioning and Gambling: Performance on the Trail Making Test is Associated with Gambling Problems in Older Adult Gamblers

ABSTRACT

Rates of gambling problems in older adults have risen with increased accessibility of gambling venues. One possible contributor to problem gambling among older adults is decreased self-control brought about by diminished executive functioning. Consistent with this possibility, Study 1 revealed that older adults recruited from gambling venues reported greater gambling problems if they also experienced deficits in executive functioning, measured via the Trail Making Test. Study 2 replicated this finding and demonstrated that problem gambling is associated with increased depression among older adults, mediated by increased financial distress. These studies provide support for the hypothesis that older adult gamblers who have executive functioning problems are also likely to have gambling problems.
