Navigating in a challenging semiarid environment: the use of a route-based mental map by a small-bodied neotropical primate

To increase efficiency in the search for resources, many animals rely on their spatial abilities. Specifically, primates have been reported to use mostly topological and rarely Euclidean maps when navigating in large-scale space. Here, we aimed to investigate if the navigation of wild common marmosets inhabiting a semiarid environment is consistent with a topological representation and how environmental factors affect navigation. We collected 497 h of direct behavioral and GPS information on a group of marmosets using a 2-min instantaneous focal animal sampling technique. We found that our study group reused not only long-route segments (mean of 1007 m) but entire daily routes, a pattern that is not commonly seen in primates. The most frequently reused route segments were the ones closer to feeding sites, distant to resting sites, and in areas sparse in tree vegetation. We also identified a total of 56 clustered direction change points indicating that the group modified their direction of travel. These changes in direction were influenced by their close proximity to resting and feeding sites. Despite our small sample size, the obtained results are important and consistent with the contention that common marmosets navigate using a topological map that seems to benefit these animals in response to the exploitation of clustered exudate trees. Based on our findings, we hypothesize that the Caatinga landscape imposes physical restrictions in our group’s navigation such as gaps in vegetation, small trees and xerophytic plants. This study, based on preliminary evidence, raises the question of whether navigation patterns are an intrinsic characteristic of a species or are ecologically dependent and change according to the environment.

     

Parenting Styles and Suicidal Ideation in Adolescents: Mediating Effect of Attachment

The present study aims to analyze the role of parenting styles in the development of suicidal ideation in adolescents, as well as test the mediating role of attachment to parents in the association between authoritative, authoritarian and permissive parenting style and suicidal ideation. The sample was made up of 604 individuals, aged between 15 and 18. In order to gather data, the Styles & Dimensions Questionnaire: Short Version, the Father/Mother Attachment Questionnaire and the Suicidal Ideation Questionnaire were used. The results suggest that the relations with parents, which are characterized by inhibition of exploration and of individuality, contribute to an emotional maladjustment being positively associated with suicidal ideation (r?=?.26 to r?=?.28). This confirmed the mediating role of parental attachment in the association between authoritative and permissive parenting styles from father and mother to suicidal ideation. It was also verified also a partial mediation, through the attachment to parents, in the association between the parent’s authoritarian style and the mother’s permissive styles and suicidal ideation. Furthermore, it was found the presence of total mediation, by throughout to attachment to the father, in the association between the father’s permissive style and suicidal ideation. The results suggest the importance of adopting authoritative parenting styles, since they seem to facilitate the development of the quality of attachment with parents. The results were analyzed in light of the attachment theory, taking into consideration the importance of parenting styles in understanding the processes inherent to suicidal ideation in adolescence.     

The perceived vulnerability to disease scale: Cross-cultural measurement invariance and associations with fear of COVID-19 across 16 countries

Using cross-sectional data from N = 4274 young adults across 16 countries during the COVID-19 pandemic, we examined the cross-cultural measurement invariance of the perceived vulnerability to disease (PVD) scale and tested the hypothesis that the association between PVD and fear of COVID-19 is stronger under high disease threat [that is, absence of COVID-19 vaccination, living in a country with lower Human Development Index (HDI) or higher COVID-19 mortality]. Results supported a bi-factor Exploratory Structural Equation Modeling model where items loaded on a global PVD factor, and on the sub-factors of Perceived Infectability and Germ Aversion. However, cross-national invariance could only be obtained on the configural level with a reduced version of the PVD scale (PVD-r), suggesting that the concept of PVD may vary across nations. Moreover, higher PVD-r was consistently associated with greater fear of COVID-19 across all levels of disease threat, but this association was especially pronounced among individuals with a COVID-19 vaccine, and in contexts where COVID-19 mortality was high. The present research brought clarity into the dimensionality of the PVD measure, discussed its suitability and limitations for cross-cultural research, and highlighted the pandemic-related conditions under which higher PVD is most likely to go along with psychologically maladaptive outcomes, such as fear of COVID-19.     

Work Context Support and Portuguese Soldiers’ Well-Being: The Mediating Role of Autonomous Motivation

Using self-determination theory ( Deci & Ryan, 2008 Deci, E. L., & Ryan, R. M. (2008). Self-determination theory: A macrotheory of human motivation, development, and health. Canadian Psychology, 49, 182–185. 10.1037/a0012801[Crossref], [Web of Science ®] , [Google Scholar]) as the theoretical framework, we tested a model for this study that considers soldiers’ perceptions of organizational support and leader–member exchange (LMX), work motivation, and well-being at work. The hypothesized model was tested using a representative sample of 1,045 Portuguese soldiers. Results revealed that autonomous work motivation was significantly related to both contextual factors (organizational support and LMX). In addition, autonomous work motivation was positively related to work engagement and negatively related to burnout, and controlled motivation showed the opposite pattern. More interesting, the results showed that autonomous work motivation as a mechanism that helped to explain the relationship between both contextual factors and workplace well-being. The present results underscore the importance of understanding the mechanisms through which higher work engagement and lower burnout take place, eventually leading to appropriate interventions.     

Impulsivity Mediates the Relationship between Future Orientation and Juvenile Deviancy

Both future orientation and impulsivity are intrinsic parts of an adolescent’s self-control, and empirical evidence clearly establishes them as crucial features on the origin of juvenile deviant behavior. However, we do not yet fully understand how these variables relate in explaining deviant conduct. In the present study, we tested a mediation model between these variables among 126 Portuguese adolescents. Findings support the mediation model in analysis, namely that impulsivity fully mediates the effect of future orientation on deviant behavior. In conclusion, our results suggest that lesser future orientated youth develop impulsive behavior which, in turn, explains their higher deviant conduct.     

The high-performance work system and commitment of the Portuguese Navy personnel

This study evaluates the relationship between the high-performance work system (HPWS) as perceived by the Portuguese Navy military and their affective (AC), normative (NC), and continuance commitment (CC). The sample is representative and composed of 1,003 individuals (officers, warrant/petty officers, and seamen—as a reference, these last two categories are called ratings in the British Royal Navy, and enlisted in the United States Navy) from different naval units. A structural models analysis was carried out, and the results showed, as expected, that the perception of an HPWS was positively related to the commitment of the military personnel, in both its affective and normative dimensions. Nevertheless, contrary to our expectations, we also observed that the perception of an HPWS was positively related to the continuance commitment as well. On the other hand, we examined the moderator role played by the professional category—the relationship between the perception of the HPWS and the AC was stronger in commissioned officers and seamen than in warrant and petty officers—and by the contractual relationship. In the latter, the relationship between the HPWS and the AC and the CC was stronger in the individuals having a fixed-term contract than in those with a permanent position. The theoretical and practical implications of these results will be discussed.     

Different temporary work status, different behaviors in organization

This study examined the contributions of the psychological contract framework to an understanding of the effects of different work statuses on employees’ behavior. We compared temporary firm workers (n=71) with core workers (n=268) and direct-hire temporary workers (n=149) with core workers (n=42) in two different samples. As expected, temporary firm workers consider that they receive fewer socio-emotional inducements from the organization they work for (opportunities for promotion, career development, long-term employment), but direct-hire temporary workers who succeeded in having their contracts extended had a psychological contract in which socio-emotional components predominated. A psychological contract with a predominance of socio-emotional components was important for organizations because it mediated the influence of work status on civic virtue behaviors on the part of temporary firm workers, and directly and positively influenced these behaviors in direct-hired temporary workers (behaviors as assessed by their supervisors). Contrary to the hypothesis, psychological contract had a direct and positive influence on the in-role behavior of direct-hire temporary workers. The implications of the findings for psychological contract research are discussed.     

Doddering but dear … even in the eyes of young children? Age stereotyping and prejudice in childhood and adolescence

This study aims to explore age prejudice, and to examine age stereotyping in children and adolescents by adopting the Stereotype Content Model (SCM) as a theoretical framework. It was hypothesised that children are socialised into adopting an ambivalent representation of old age (socialisation hypothesis) and that this cognitive bias becomes weaker in adolescence due to greater cognitive maturity (developmental hypothesis). By analysing representative data from Portugal (European Social Survey; N = 2367), it was ascertained that the ambivalent age stereotype (higher evaluations of warmth than competence for older people) is indeed a shared social representation of older people in Portuguese society. A total of 103 Portuguese children (6–10 year olds) and adolescents (11–15 year olds) were then sampled from a local school and responded to age‐appropriate measures assessing age prejudice as well as age stereotypes. Contrary to previous studies, the findings do not provide evidence for the existence of age prejudice because both children and adolescents reported positive feelings towards older people. However, the socialisation hypothesis was corroborated by showing that the ambivalent old age stereotype was already present in childhood. Contrary to the stipulated developmental hypothesis, the magnitude of this cognitive bias was very similar in adolescence.     

Living Well in Later Life: The Influence of Sense of Coherence,and Socio-Demographic,Lifestyle and Health-Related Factors on Older Adults’ Satisfaction with Life

This study aims at exploring a structural model of satisfaction with life’s (SWL) predictors in a cross-national sample of older adults. A quantitative approach was followed with a cross-sectional study design. A community-dwelling sample of 1,234 older adults from four different nationalities residing in Portugal, was assessed regarding SWL, sense of coherence (SOC) and socio-demographic, lifestyle and health-related characteristics. Sampling was performed in lifelong learning centres’ message boards and local community centres’ list-serves in the Lisbon metropolitan area and in the Algarve region. Structural equation modeling was used to investigate a structural model of the self-reported SWL, comprising SOC, socio-demographic characteristics (age, sex, education, marital and professional status, household, adult children, income, living setting and religion), as well as lifestyle and health-related characteristics (physical activity, recent disease and medication). Significant predictors are SOC (β?=?0.733; p?<?0.001), religion (β?=?0.725; p?<?0.001), income (β?=?0.551; p?<?0.001), adult children (β?=?0.546; p?<?0.001), education (β?=??0.403; p?<?0.001), living setting (β?=??0.292; p?<?0.001) and medication (β?=??. 197; p?<?0.001). The variables accounted for 24.8 % of the variability of SWL. Moreover, differences between the four nationality groups (F _{(3, 671)}?=?3.671, p?=?0.066) were not found concerning SWL. Sense of coherence is the strongest predictor of self-reported SWL. Other predictors are religion, income, adult children, education, living setting and medication. The four nationalities did not present significant differences, concerning SWL. This study points out the potential factors that influence older adults’ SWL, in particular SOC, religion and income, as promoters of aging well, within a salutogenic model of health for older populations.
