Late backward effects in the refractory period paradigm: effects of Task 2 execution on Task 1 performance

The central bottleneck model assumes that in the psychological refractory paradigm, Task 1 performance is independent of Task 2 demands. Previous studies, however, have reported backward crosstalk effects of motor demands in Task 2 on Task 1 performance. These effects have been attributed to interference at the central level. The present study aimed to isolate more directly potential backward effects at the motor level. Therefore, in three experiments, movement distance in Task 2 was manipulated using a guided ballistic movement. The results showed that movement distance in Task 2 affected reaction time as well as response duration in Task 1. It is argued that the backward effect observed in this study is due to response coupling at motor rather than central levels.     

Factor structure and measurement invariance of the Wisconsin Schizotypy scales across gender and age

The Wisconsin Schizotypy Scales are among the most widely used instruments for the assessment of psychosis proneness. The main goal of the present work was to study the dimensional structure underlying the Revised Physical Anhedonia Scale (RPhA), the Revised Social Anhedonia Scale (RSAS), the Magical Ideation Scale (MIS) and the Perceptual Aberration Scale (PAS). It was also explored whether the dimensions underlying these scales were invariant across gender and age. The sample was made up of 710 university students with a mean age of 19.8 years (SD = 1.9). The results showed that the dimensional structure of the Wisconsin scales was similar to that found in previous studies, displaying a Positive dimension and a Negative dimension, the Social Anhedonia Scale being related to both dimensions. Moreover, the factor structure of the schizotypy scales was found to be invariant across participants' gender and age.     

Emerging ICT for Citizens’ Veillance: Theoretical and Practical Insights

In ubiquitous surveillance societies, individuals are subjected to observation and control by authorities, institutions, and corporations. Sometimes, citizens contribute their own knowledge and other resources to their own surveillance. In addition, some of “the watched” observe “the watchers” “through” sous‐veillant activities, and various forms of self-surveillance for different purposes. However, information and communication technologies are also increasingly used for social initiatives with a bottom up structure where citizens themselves define the goals, shape the outcomes and profit from the benefits of watching activities. This model, which we define as citizens’ veillance and explore in this special issue, may present opportunities for individuals and collectives to be more prepared to meet the challenges they face in various domains including environment, health, planning and emergency response.     

The Role of Positive Psychology Constructs in Predicting Mental Health and Academic Achievement in Children and Adolescents: A Two-Year Longitudinal Study

This longitudinal study presents the first examination of the relation between positive psychology constructs, mental health and academic achievement of students in Portugal. Using a sample of 367 middle-school students, the study revealed that crosssectional and longitudinal patterns of correlations between positive variables were consistent with expectations for the most part and suggested that hope, life satisfaction and self-worth have meaningful relations with mental health and academic achievement. In addition, no significant changes were found between the variables in study across the administrations and throughout the two cohorts, and all the variables in study demonstrate moderate to high stability across a 1- and 2-year time frame. Hope predicts students?? academic achievement, and life satisfaction was the strongest predictor of mental health, over 2-years. The implications of the findings are discussed with reference to prior studies and for future research.     

Psychometric properties of the Spanish version of the Frost Multidimensional Perfectionism Scale in women

This instrumental study was designed to analyze the psychometric properties of the Spanish version of the Frost Multidimensional Perfectionism Scale (FMPS). The total sample was made up of 582 female college students, with a mean age of 21.68 (SD= 4.45). The results of confirmatory factor analysis identified the six-factor solution proposed by the original authors as the best factor structure, with acceptable fit indices. Cronbach's alpha coefficient was .93 for the FMPS total score and ranged from .74 to .91 for the subscales. Test-retest reliability suggested a good temporal stability of the FMPS total score [ICC= .89 (95% CI= .80-.94)] and its subscales. Results showed moderate to high associations between the Spanish version of the FMPS and other measures of perfectionism. The Spanish version of FMPS has shown satisfactory psychometric properties to be used in women. Future research should replicate these findings in broader samples, in clinical populations, and use longitudinal designs to determine whether perfectionism is a risk factor for psychopathology in women.
