Gender and its contribution to the prediction of cognitive abilities at 5 years

Gender-related differences in the prediction of five year-olds' cognitive abilities from measures of distal environment, proximal environment and infant test scores were examined in a random sample of 93 boys and 90 girls. Distal environmental data included maternal IQ, maternal and paternal education. Proximal environmental data included two variables derived from the Home Screening Questionnaire: the Home Questions and the Toy Checklist. The Bayley MDI was administered at age 13 months, whereas WPPSI-R was used as cognitive outcome measure at age 5 years. The relationship between paternal education and child IQ, and between proximal environmental variables and child IQ was significantly stronger for boys than for girls. The associations between proximal environment and IQ in boys, were accounted for by the distal environmental variables. Bayley MDI correlated significantly higher with girls' IQ compared to boys' IQ. Findings are discussed in terms of parental gender-differentiated socialization processes.     

Rat defensive behavior: burying noxious food.

In Experiment 1, rats living in chambers containing bedding material were injected with a toxicosis-producing dose of lithium chloride shortly after their initial taste of sweetened condensed milk. They consumed no additional milk and used the bedding to bury the spout through which the milk had been delivered, although they did not bury a concurrently available water spout. In another control condition, rats did not bury a spout containing a novel solution (saccharin) not paired with toxicosis. In Experiment 2, rats did not bury a milk spout until milk consumption was followed by toxicosis. In Experiment 3, rats buried a spout containing Tabasco pepper sauce but not a concurrently available water spout. Thus, burying the food source appears to be an integral component of the rat's defensive reaction to noxious food.     

Driving simulation sickness and the sense of presence: Correlation and contributing factors

Driving simulators are useful and effective tools for conducting studies in the field of traffic safety. Simulation sickness (SS) and the sense of presence (SP) are two well-known factors that could affect the results of the driving simulator experiments. This study investigated the relationship between SP and SS in a medium-fidelity driving simulator. Additionally, the impact of the road environment (urban arterials or rural expressways) on these subscales was investigated. Data was collected by means of self-reported questionnaires, which were conducted after the participants have driven the simulation scenarios in a fixed-base medium-fidelity driving simulator. A total of 125 drivers participated in this study. Results showed that females reported significantly higher SS scores than males. An increasing trend in the SS was observed with the increase of age. Importantly, designing buildings that replicate a real-world environment could increase SP and decrease SS. Moreover, designing high quality and resolution scenarios could also increase SP, thus decreasing the severity of SS symptoms. The results of this study can help researchers using medium-fidelity driving simulators to know the influencing factors for each subscale of SP on SS. Adjustments in the driving simulator and scenario settings as well as additional training exercises for higher speed scenarios can be beneficial in reducing the severity of SS.     

The role of vulnerable environments in support for homegrown terrorism: Fieldwork using the 3N model

The 3N model of radicalization proposes that violent radicalization is the result of the contribution of needs, networks, and narratives. Although research has mainly been supportive of this perspective, a substantial amount of ground remains uncovered regarding the network component of the model. Within this framework, we examine why individuals living in certain social environments tend to harbor more positive attitudes toward homegrown terrorism than others. Building on prior research, we hypothesized that individuals living in social environments known to be vulnerable (vs. less vulnerable) are more likely to experience a sense of significance loss (i.e., lack of social integration, perceived conflicts between religious groups), find solace in religious social networks (i.e., mosques), and thus adhere to radical narratives (i.e., legitimization of terrorism). A study with 365 young Muslims from different cities in Spain (Almería, Barcelona, Ceuta, and Melilla)supported these predictions. Theoretical and practical implications for the study of violent extremism are discussed.     

The testing environment as an explanation for unproctored internet‐based testing device‐type effects

Device‐type effects on cognitive tests appear to covary with whether unproctored internet‐based test (UIT) scores were obtained operationally or nonoperationally. The present study examined whether the testing environment and distractions therein—one of three contextual factors identified as plausible explanations—accounts for this covariation. Four‐hundred and twenty‐five college students were randomly assigned to one of three conditions which differed by the testing environment and device used to complete a cognitive test. Test scores did not differ between conditions despite greater distractions reported by those who tested in the distracting environment. Results were replicated within‐study, and suggest that the self‐selection and testing‐stakes hypotheses warrant subsequent empirical examination as explanations for the differences in device‐type effects observed in operational and nonoperational settings.     

Environnement lumineux et anxiété des patients en service d’IRM

BackgroundMagnetic Resonance Imaging (MRI) is a medical imagery exam, which is considered stressful/worrying for patients. This anxiety is related to several factors: negative beliefs linked to the lack of knowledge about the procedure of the exam, duration, noise of the MRI, etc. Several interventions, before and during the MRI were proposed and evaluated with the aim of reducing anxiety for patients (information given to patients, psychological preparation before the exam and hypnosis, aromatherapy, sedation, environment and positioning of the patient). While the health service is more and more centered on cost-efficiency and pressure for greater patient throughput, it is important to find appropriate interventions to improve patient tolerance of MRIs.ObjectiveThe objective of this study was to compare anxiety of patients based on the MRI luminous environment.Methods208 patients aged 18–70 years participated in the study. Four subgroups were created according to the presence or absence of luminous environment, screen and music: G1 (60 participants, with luminous environment, without screen, music with fast tempo); G2 (60 participants, with luminous environment, with screen, music with slow tempo); G3 (27 participants, without luminous environment, without music); G4 (61 participants, without luminous environment, music with fast tempo). All participants completed a questionnaire to evaluate their anxiety regarding the exam (anxiety-state, AE) and in everyday life (anxiety-trait, AT): STAI-Y. Open questions were also asked to participants in order to gain an understanding of their experience of the exam (positive points and suggestions for improvements).ResultsThe results showed a significant difference between the groups of the AE: patients of group G1 showed more AE than patients in group G2 (p = 0.037), patients of group G2 showed less AE than those of group G3 (p = 0.001), and patients of group G3 showed more AE than patients in group G4 (p = 0.019). No significative difference was found between the 3 groups in the AT. The participants who underwent exams in a room with a luminous environment equipped with a screen with slow tempo music reported more satisfaction and offered fewer suggestions for improvement compared with the two other groups.ConclusionThis study has revealed that the environment in which patients undergo their exam affects their level of anxiety during the exam. A luminous environment equipped with a screen led to a considerable decrease in patient anxiety during the MRI exam. Technological innovations are allowing the patient to be the center of radiographers focus more and more. Trying to priorities improvement of patient well-being consequently facilitates their work. Taking into account the cost and increasing number of medical imagery exams, prevention of anxiety and its undesirable side-effects is not only important for patients, but also avoids wastage of staff and of time. The results of this study should encourage health centers to invest in these new installations, keeping in mind that new technologies can never replace information and support offered before the exam by radiologists and radiographers.     

The Map and the Territory: Complexity in Biology

In business administration or in economics it is absolutely relevant not to consider indexes like profit growth rate or gross domestic product as exhaustive indexes for economic wealth. Likewise, in biology it is important not to confuse the representation of life with life itself. The most important concepts in biology are information, memory, structure, plasticity, and robustness. Information is the difference that makes the difference. Memories are information registered in an organism. Plasticity is the capacity of a living organism to change its own structure/sets of behaviors for having a competitive advantage. Robustness is the ability of a living organism to resist environmental changes without changing its own structure/sets of behavior, and fragility is when a living organism undergoes changes in its own structure without being able to resist non-adaptive changes.     

“Put the blame on…others!”: The battle of cyclists against pedestrians and car drivers at the urban environment. A cyclists’ perception study

The main hypothesis of the paper is that cyclists tend to blame primarily car drivers, for the conflict events they have experienced with cars, but they do not have the same intention for the conflict events with pedestrians. For this purpose, 306 cyclists were interviewed through a revealed questionnaire survey and 64% revealed that they had experienced a conflict with a pedestrian whereas 55% revealed that they had experienced a conflict with a car. From the responses, two linear regression models were developed, with the perceived responsibility considered as the dependent variable.The cycling–pedestrian model indicated that cyclists who also have car accessibility, tend to blame primarily the pedestrians for the incidents, compared to cyclists who do not possess a car. Further, cyclists tend to give less responsibility to pedestrians for incidents occurred at sidewalks, crosswalks, etc. compare to incidents occurred at shared use paths. In addition, cyclists do not blame pedestrians for conflicts occurred primarily at sidewalks and crosswalks; places were pedestrians are considered to have the priority. Finally, cyclists aged between 55 and 64 years old, are giving less responsibility to pedestrians for the incident, compare to cyclists aged between 25 and 39 years old.On the other hand, the cycling–car model showed that an illegal cyclist’s movement at a road segment can reduce by half the responsibility the cyclists give to the car drivers, compare to the responsibility they give when the latter have an aggressive driving behavior. It was also found that cyclists, who tend to cycle less than 1 h, do not blame so much the car drivers for the incident, compared to cyclists that cycle for longer. Finally, cyclists who prefer the bicycle lane to be located along the road instead at the sidewalk, tend to accuse less the drivers for the incident.
