Consequences of job insecurity and the moderator role of occupational group

In recent decades, transformations in organizations and the labour market have produced an increase in employee job insecurity. In response to this situation, workers present different negative reactions. However, the intensity of these reactions varies across studies that have investigated the outcomes of job insecurity. One possible explanation for this inconsistency may lie in the influence of other factors, such as the occupational group (Sverke et al., 2002). The aim of this study is to provide additional evidence about the relationship between job insecurity and its outcomes (i.e., life satisfaction, job satisfaction, perceived performance and organizational commitment), and examine the moderator role of occupational group in this relationship. The sample was composed of 321 employees from different Spanish organizations. The results showed that job insecurity was directly and negatively related to life satisfaction, job satisfaction and organizational commitment, and they suggest that occupational group moderated relations between job insecurity and three studied outcomes. In the case of life satisfaction and perceived performance, this relationship was stronger among blue collar workers. The relationship between job insecurity and job satisfaction was stronger in white collar workers. The implications and limitations of this study are discussed.     

The uncertain universality of the Macbeth effect with a Spanish sample

Recently a psychological mechanism has been proposed between bodily purity and moral purity: the "Macbeth effect". The act of washing their hands seems to free individuals of their guilt. However, the universality of this psychological mechanism is an empirical question that should be studied. In four studies we replicated the original Zhong & Liljenquist's experiments with Spanish samples. We were unsuccessful in replicating the Zhong & Liljenquist's results that supported cleansing as a psychological mechanism for compensating guilty: results couldn't confirm an increased mental accessibility of cleansing-related concepts or even a greater desire for cleansing products, neither a greater likelihood of taking antiseptic wipes. In addition we didn't find that physical cleansing alleviates the upsetting consequences of unethical behaviour. Spanish samples showed sensibility to morality and helping behaviour but not with cleansing as a way to reduce their threatened morality.     

Evidence of different developmental trajectories for length estimation according to egocentric and allocentric viewpoints in children and adults

This study investigated the influence of egocentric and allocentric viewpoints on a comparison task of length estimation in children and adults. A total of 100 participants ranging in age from 5 years to adulthood were presented with virtual scenes representing a park landscape with two paths, one straight and one serpentine. Scenes were presented either from an egocentric or allocentric viewpoint. Results showed that when the two paths had the same length, participants always overestimated the length of the straight line for allocentric trials, whereas a development from a systematic overestimation in children to an underestimation of the straight line length in adults was found for egocentric trials. We discuss these findings in terms of the influences of both bias-inhibition processes and school acquisitions.     

Essentialism and the expression of social stereotypes: a comparative study of Spain, Brasil and England

Over the past few years, one of the most productive directions in the study of the activation and application of stereotypes has been provided by the essentialist concept of categorization. The research presented here studied the impact of two dimensions of essentialist beliefs--naturalism and entitativity-by using data collected from Brazil, Spain and England. The aim was to test whether there was a greater degree of essentialization among the naturalizable categories (sex, age and race) than among the entitative categories (economic condition, religion, political orientation, nationality and social condition). The results not only showed that participants hold more essentialist beliefs with regard to naturalistic categories but also showed the differences in the degree of essentialization across the three cultures. A discussion is conducted on the implications of the present findings, and on the heuristic value of the theoretical model (of the bidimensional nature of essentialism) adopted by this research.     

Discrepancy between radiographic damage and functional disability in elderly people with osteoarthritis: the role of pain coping strategies

The aim of this study is twofold. First, to assess the level of agreement between radiographic damage and functional disability in older people with osteoarthritis. And second, to assess the role of coping skills and sensory pain parameters as sources of disagreement between these variables. To achieve this objective we assess, in a sample of 104 older people with osteoarthritis, the following variables: functional capacity, radiographic damage, pain coping strategies, pain intensity, pain frequency and pain duration. The results show a non-linear relationship between radiographic damage and functional disability, modified by the levels of the two variables. There was maximum agreement between low levels of radiographic damage and of functional impairment, whilst agreement decreased for moderate and high levels of radiographic damage. Certain coping strategies may help to explain this disparity.     

Sociometric types and social interaction styles in a sample of Spanish adolescents

This study analyzed the relationship between social interaction styles and sociometric types in a sample of 1,349 (51.7% boys, and 48.3% girls) Spanish adolescents. The results revealed that the proportion of prosocial adolescents nominated as liked by peers was significantly higher than prosocial with social anxiety, whereas the proportion of aggressive adolescents nominated by peers as rejected was significantly higher than the proportion of rejected-prosocial and rejected-with social anxiety. The percentages of sociometric types and social interaction styles varied significantly according to gender and academic grade. Logistic regression analyses showed that being prosocial was 48% more likely when adolescents are nominated by peers as liked, whereas being prosocial was 41% and 79% less likely when adolescents were nominated as rejected and neglected, respectively. Furthermore, prosocial adolescents were 67% more likely nominated by peers as liked, and were less likely nominated as rejected (42%) and neglected (78%). Finally, being neglected was 83% more likely in aggressive adolescents.     

Mapping numerical processing, reading, and executive functions in the developing brain: an fMRI meta-analysis of 52 studies including 842 children

Tracing the connections from brain functions to children's cognitive development and education is a major goal of modern neuroscience. We performed the first meta-analysis of functional magnetic resonance imaging (fMRI) data obtained over the past decade (1999-2008) on more than 800 children and adolescents in three core systems of cognitive development and school learning: numerical abilities, reading, and executive functions (i.e. cognitive control). We ran Activation Likelihood Estimation (ALE) meta-analyses to obtain regions of reliable activity across all the studies. The results indicate that, unlike results usually reported for adults, children primarily engage the frontal cortex when solving numerical tasks. With age, there may be a shift from reliance on the frontal cortex to reliance on the parietal cortex. In contrast, the frontal, temporo-parietal and occipito-temporal regions at work during reading in children are very similar to those reported in adults. The executive frontal regions are also consistent with the imaging literature on cognitive control in adults, but the developmental comparison between children and adolescents demonstrates a key role of the anterior insular cortex (AIC) with an additional right AIC involvement in adolescents.     

Efficacy and feeling of a vibrotactile Frontal Collision Warning implemented in a haptic pedal

A haptic pedal has been designed to emulate the behaviour of a common vehicle pedal and render superimposed vibrations with different characteristics. It was installed in a driving simulator, as an accelerator pedal with the secondary function of a vibrotactile Frontal Collision Warning (FCW). The efficacy and feeling of this solution was tested with 30 subjects using vibrotactile signals with 0.50, 1.05, and 1.60 Nm, at 2.5, 5, and 10 Hz, against a baseline visual FCW. Participants had to match the speed of a leading vehicle when the FCW was triggered. Their braking response was evaluated in terms of brake reaction time, matching speed time, control of velocity and headway reduction. Driver’s feelings were assessed with Kansei methodologies. Haptic stimuli were found to be more effective than visual signals, and the characteristics of the vibration also influenced the results. The best performance was achieved at the maximum amplitude, and in the range between 5 and 10 Hz. The perceived functionality and discomfort followed a trend coherent with the objective measurements. The conclusions of this study may be applied to develop effective and safe warning systems in vehicles, limiting the annoyance that they might cause to drivers.     

The ability to regulate emotion is associated with greater well-being, income, and socioeconomic status

Are people who are best able to implement strategies to regulate their emotional expressive behavior happier and more successful than their counterparts? Although past research has examined individual variation in knowledge of the most effective emotion regulation strategies, little is known about how individual differences in the ability to actually implement these strategies, as assessed objectively in the laboratory, are associated with external criteria. In two studies, we examined how individual variation in the ability to modify emotional expressive behavior in response to evocative stimuli is related to well-being and financial success. Study 1 showed that individuals who can best suppress their emotional reaction to an acoustic startle are happiest with their lives. Study 2 showed that individuals who can best amplify their emotional reaction to a disgust-eliciting movie are happiest with their lives and have the highest disposable income and socioeconomic status. Thus, being able to implement emotion regulation strategies in the laboratory is closely linked to well-being and financial success.
