Creativity and Psychopathology: Sex Matters

The association between creativity and psychopathology has, for decades, been a focus of heated debate fuelled by contradictory findings. Nevertheless, the findings suggest complex associations between creativity and psychopathology. Other studies have investigated the association between creativity and sex, with inconsistent results. The aim of this study was to investigate the influence of sex on the association between creativity and psychopathology. In total, 106 participants (37 men and 69 women) were administered the Symptom Check List (SCL90-R) and the CREA test of creativity. There were no significant associations in the total sample between the variable creativity and the psychopathology scales. Strikingly, when the sample was divided by gender, a moderate-to-high significant positive association between creativity and psychopathology was found among men. Previously, the associations between creativity and gender and between creativity and psychopathology were studied in relative isolation from each other, rather than together as the main focus of research. Our results suggest that the complex associations between psychopathology and creativity differ between men and women.     

Psychometric Properties of the Mental Health Continuum-Short Form: A Study of Portuguese Speaking Children/Youths

The development of measures of children and adolescents’ subjective well-being is crucial to the conceptualization and evaluation of positive mental health. The aim of this study was to investigate the factorial structure and invariance of the Mental Health Continuum-Short Form (MHC-SF—adolescents) across children and youths. Participants were from two different samples: 208 elementary school children (sample 1) and 216 middle school youths (sample 2). Results confirmed the three-dimensional structure of subjective well-being in both samples. The three sub-scales of the MHCSF yielded high internal consistency and results from the HTMT85 indicated discriminant validity. Measurement invariance testing across three different age groups (7–8, 9–10 and 11–14 years) confirmed the full metric and approximate scalar invariance of the MHC-SF. Full scalar invariance was achieved across gender. The study also compared the latent means for mental well-being in the three age groups, and found that the younger groups showed significantly higher levels of wellbeing. The present research study strongly suggests that the MHC-SF (adolescents) is an appropriate instrument to measure the positive mental health and well-being of children and pre-adolescents as multidimensional construct.     

Polemics on Ethical Aspects in the Compost Business

This paper focuses on compost use in overpasses and underpasses for wild animals over roads and other similar linear structures. In this context, good quality of compost may result in faster and more resistant vegetation cover during the year. Inter alia, this can be interpreted also as reduction of damage and saving lives. There are millions of tones of plant residue produced every day worldwide. These represent prospective business for manufacturers of compost additives called “accelerators”. The opinions of the sale representatives’ with regards to other alternatives of biowaste utilization and their own products were reviewed. The robust analyzes of several “accelerated” composts revealed that the quality was generally low. Only two accelerated composts were somewhat similar in quality to the blank sample that was produced according to the traditional procedure. Overlaps between the interests of decision makers on future soil fertility were weighed against the preferences on short-term profit. Possible causes that allowed the boom of these underperforming products and the possible consequences are also discussed. Conclusions regarding the ethical concerns on how to run businesses with products whose profitability depends on weaknesses in the legal system and customer unawareness are to follow.     

The moderating impact of temporal separation on the association between intention and physical activity: a meta-analysis

Previous meta-analyses have estimated that the intention–behaviour association in physical activity (PA) is large in magnitude. However, these prior meta-analyses have also revealed a large degree of heterogeneity, suggesting the presence of moderating variables. This study examines the impact of one such moderator, testing the hypothesis that the magnitude of the association between intention and behaviour decreases as the temporal separation between the two increases. A systematic literature search was used to identify published and unpublished studies that met the inclusion criteria. A random-effects meta-regression was conducted to test the study hypothesis. A total of 78 journal articles and 11 unpublished dissertations were identified, yielding 109 effect sizes. The mean number of weeks between the measurement of intention and behaviour was 5.4 (SD = 6.6, range = .43, 26). The average correlation between intention and behaviour was r = 0.51. In line with theoretical predictions, temporal separation was a significant moderator of the intention–behaviour correlation (B = ?.014, p < .001) and explained 24% of the between-study variance. This result remained unchanged when entered simultaneously with several control variables. The results of this analysis have important implications both for researchers and for intervention designers aiming to increase rates of PA.     

Jealousy Revisited: Recent Philosophical Work on a Maligned Emotion

Taking as its starting point a previous work by the author which reviewed early philosophical sources on jealousy and proposed both a conceptual and moral account of this much-maligned emotion, the present article reviews the relevant philosophical literature from the last decade or so. Most noticeable is how scarce those sources still are. Special attention is given, however, to a new conceptual model proposed by Purshouse and Fredericks which rejects the standard architectonic of jealousy as a three-party compound emotion. While the essential contours of the new model are rejected, Fredericks is shown to offer some powerful misgivings about putative instrumentalist defences of jealousy. In addition to this new model, a number of other recent writings about jealousy – historical, conceptual and moral – are subjected to critical scrutiny in this overview article.     

Math anxiety: A review of its cognitive consequences,psychophysiological correlates,and brain bases

A decade has passed since the last published review of math anxiety, which was carried out by Ashcraft and Ridley (2005). Given the considerable interest aroused by this topic in recent years and the growing number of publications related to it, the present article aims to provide a full and updated review of the field, ranging from the initial studies of the impact of math anxiety on numerical cognition, to the latest research exploring its electrophysiological correlates and brain bases from a cognitive neuroscience perspective. Finally, this review describes the factors and mechanisms that have been claimed to play a role in the origins and/or maintenance of math anxiety, and it examines in detail the main explanations proposed to account for the negative effects of math anxiety on performance: competition for working memory resources, a deficit in a low-level numerical representation, and inhibition/attentional control deficit.     

Do Pro-environmental Behaviors and Awareness Contribute to Improve Subjective Well-being?

In this paper, we study the influence of both environmental awareness and behaviors on subjective well-being (SWB). By using ordered logit techniques in a sample from Granada, a city in southern Spain, we find that concern about the environment and voluntary work actions to preserve it are relevant for SWB. When both are combined, namely when a person is concerned and volunteers, the influence on SWB is greater. These results introduce the SWB dimension in the knowledge-concern-action paradox, which states that even if the individual is concerned about the environment, this concern does not always translate into personal action to preserve it. Actions such as habits related to water saving inside the household are not significant in explaining SWB, but using devices that save water increases it. In summary, our results suggest that actions and awareness have either a positive or no significant influence on SWB, but never a negative influence.     

Symbolic representation of the number three: a study with three-year-old children from contrasting socioeconomic environments

The goal of the present study was to compare a range of aspects in children’s symbolic knowledge about the number three among two groups of three-year-olds from contrasting socioeconomic backgrounds. Every child was presented with five tasks that focused on the number three and that had cognitive demands of different complexity: expressing their age, reciting the conventional number series up to three, quantifying a collection of three, and two tasks requiring the use of visually presented quantitative information.The results showed the same order of difficulty of the tasks in both socioeconomic groups and a clear performance difference depending on socioeconomic background. These findings show that symbolic knowledge about the number three does not come in an all or none fashion. Rather, different aspects of this symbolic competence become apparent in response to different tasks, and seem to depend largely on the socioeconomic environment in which children develop.
