Depression and sleep quality in older adults: a meta-analysis

The literature emphasizes depression and poor sleep quality as problems that affect many elderly individuals. However, these problems have been related in few studies and there is no meta-analysis performed so far on this relationship. The present research reviewed the studies performed on the subjective sleep quality in order to understand how it relates to depression in older adults. The review was conducted in January 2016 and comprised publications between 2005 and 2015. Based on the electronic databases Web of Science and EBSCO, we used the keywords ‘sleep quality’, ‘depression’, and ‘older’ to identify the empirical studies performed. After assessing the collected studies, we selected those that presented the elderly as participants, resulting in nine papers (N = 3069). A random-effects method was used to evaluate the relationship between depression and sleep. We found that an older person’s lack of good sleep quality is significantly related with depression. The main limitation of this study was the difficulty in collecting a greater number of studies. Future research should consider the importance of additional variables (e.g. moderators) in order to understand and investigate viable interventions for prevention and health promotion in the elderly.     

THE PARADOX OF BENEFICIAL RETIREMENT

Morally, when should one retire from one's job? The surprising answer may be ‘now’. It is commonly assumed that for a person who has acquired professional training at some personal effort, is employed in a task that society considers useful, and is working hard at it, no moral problem arises about whether that person should continue working. I argue that this may be a mistake: within many professions and pursuits, each one among the majority of those positive, productive, hard working people ought to consider leaving his or her job.     

An Integrated Model for the Study of Teacher Motivation

Des recherches récentes ont montré que les enseignants souffraient plus que d’autres groupes professionnels d’un manque de motivation au travail. Une compréhension globale de la motivation des enseignants exige un modèle adéquat. L’objectif principal de cette recherche était de proposer et de mettre à l’épreuve un modèle de la motivation des enseignants qui intégre des concepts de plusieurs théories cognitivo‐motivationelles. Le modèle intégré s’appuie sur la schéma expectation‐valence et celui de l’incapacité acquise, mais surmonte quelques‐unes de leurs imperfections. L’échantillon était composé de 272 enseignants des écoles élémentaires et secondaires du Portugal. Ils ont répondu à une série d’inventaires destinés à mesurer leurs expectations de contrôle, de succès et d’efficacité, leurs attributions, leur motivation intrinsèque, la valence de leurs buts perçus et comment tout ceci interagit pout agir sur l’engagement professionnel (la variable exogène du modèle). Les analyses des coefficients de pistes et de la variance des variables endogènes valident le modèle intégré proposé ici et suggèrent des stratégies de formation pour accroître la motivation des enseignants. Recent studies show that teachers suffer more than other professional groups from the occupational lack of motivation. A global understanding of teacher motivation requires an adequate framework for its study. The main goal of the current research was to propose and test a model of teacher motivation that integrates constructs from several cognitive‐motivational theories. This integrative model starts from the perspectives of Expectancy‐Value and Learned Helplessness but overcomes some of the limitations of each. The participants were 272 elementary and secondary teachers in Portugal. They responded to a series of inventories designed to measure their expectancies of control, success and efficacy, attributions, intrinsic motivation and perceived goal value levels, and how these interact to influence professional engagement (the model's exogenous variable). Analyses of path coefficients and the variance of endogenous variables support the proposed integrated model and suggest strategies for teacher education that may increase teacher motivation.     

Sick body, vigilant mind: the biological immune system activates the behavioral immune system

Activation of the behavioral immune system has been shown to promote activation of the biological immune system. The current research tested the hypothesis that activation of the biological immune system (as a result of recent illness) promotes activation of the behavioral immune system. Participants who had recently been ill, and had therefore recently experienced activation of their biological immune system, displayed heightened attention to (Study 1) and avoidance of (Study 2) disfigured individuals--cognitive and behavioral processes reflecting activation of the behavioral immune system. These findings shed light on the interactive nature of biological and psychological mechanisms designed to help people overcome the threat of disease.     

Five-year-old children's difficulty with false belief when the sought entity is a person

A total of 153 children (excluding those who erred on control questions), mainly 5 and 7 years of age, participated in two experiments that involved tests of false belief. In the task, the sought entity was first at Location 1 and then, unknown to the searching protagonist, it moved to Location 2. In Experiment 1, performance was well below ceiling in 5-year-olds when the sought entity was a person, and this contrasted with a task in which the sought entity was a physical object. Performance was especially inaccurate when the sought person moved of his or her own volition rather than when the sought person was requested to move by a third party. Interestingly, 5-year-olds were more likely to nominate Location 1 when asked where the searching protagonist would look first than when asked what he or she would do next. In Experiment 2, however, 5-year-olds also tended to nominate Location 1 following a question that included the word "first" even in a test of true belief--a patently incorrect response. Altogether, the results suggest that 5-year-old children have considerable difficulty with a test of false belief when the sought entity is a person acting under his or her own volition. This suggests that 5-year-olds' handle on states of belief is surprisingly fragile in this kind of task.     

Are There Cross-Cultural Legal Principles? Modal Reasoning Uncovers Procedural Constraints on Law

Despite pervasive variation in the content of laws, legal theorists and anthropologists have argued that laws share certain abstract features and even speculated that law may be a human universal. In the present report, we evaluate this thesis through an experiment administered in 11 different countries. Are there cross-cultural principles of law? In a between-subjects design, participants (N = 3,054) were asked whether there could be laws that violate certain procedural principles (e.g., laws applied retrospectively or unintelligible laws), and also whether there are any such laws. Confirming our preregistered prediction, people reported that such laws cannot exist, but also (paradoxically) that there are such laws. These results document cross-culturally and –linguistically robust beliefs about the concept of law which defy people's grasp of how legal systems function in practice.     

The influence of rule availability and item similarity on metacognitive monitoring during categorisation

In four experiments, we examined the sources of metacognitive judgments during the categorisation of new items after the learning of old items was completed. In the rule condition, the categorisation rule was explicitly given to the participants during learning, while in the no-rule condition participants relied on feedback to infer category membership. In the transfer phase, two types of novel items were used: good and bad transfer items. Transfer items also differed in the level of similarity to their training pairs. In the rule condition, all types of transfer items were classified with high accuracy and confidence. In the no-rule condition, a dissociation between accuracy and confidence was revealed. Good transfer items were classified more accurately than bad transfer items, whereas similar items were classified with higher confidence than dissimilar items. The obtained results suggest the utilisation of two potential cues for metacognitive judgments: declarative knowledge if the correct rule is explicitly available, and item similarity if it is difficult to infer the correct rule from feedback.     

Death and the Self

It is an old philosophical idea that if the future self is literally different from the current self, one should be less concerned with the death of the future self (Parfit, 1984 ). This paper examines the relation between attitudes about death and the self among Hindus, Westerners, and three Buddhist populations (Lay Tibetan, Lay Bhutanese, and monastic Tibetans). Compared with other groups, monastic Tibetans gave particularly strong denials of the continuity of self, across several measures. We predicted that the denial of self would be associated with a lower fear of death and greater generosity toward others. To our surprise, we found the opposite. Monastic Tibetan Buddhists showed significantly greater fear of death than any other group. The monastics were also less generous than any other group about the prospect of giving up a slightly longer life in order to extend the life of another.
