A low cortisol response to acute stress is related to worse basal memory performance in older people

2014

Age-related memory decline has been associated with a faulty regulation of the hypothalamus-pituitary-adrenal axis (HPA-axis). The aim of this study was to investigate whether the magnitude of the stress-induced cortisol increase is related to memory performance when memory is measured in non-stressful conditions. To do so, declarative and working memory performance were measured in 31 men and 35 women between 55 and 77 years of age. On a different day, the magnitude of their cortisol response to acute psychosocial stress was measured. The relationship between the cortisol response and memory performance was U shaped: a low cortisol response to stress was related to poorer declarative and w…

Endothelin Antagonism: Effects of FP Receptor Agonists Prostaglandin F2αand Fluprostenol on Trabecular Meshwork Contractility

2006

Purpose This study analyzes additional mechanisms behind the ocular hypotensive effect of prostaglandin F (PGF) receptor (FP receptor) agonists PGF2alpha and fluprostenol (fluprostenol-isopropyl ester [travoprost]), which reduce intraocular pressure (IOP) in patients with glaucoma probably by enhancing uveoscleral flow. The trabecular meshwork (TM) is actively involved in IOP regulation through contractile mechanisms. Contractility of TM is induced by endothelin (ET)-1, a possible pathogenic factor in glaucoma. The involvement of FP receptor agonists in the ET-1 effects on TM function was studied. Methods The effects of FP receptor agonists on contractility of bovine TM (BTM) were investiga…

The Significance of Treasure Hunting: Past and Present

2012

It is certainly insufficient to explain treasure hunting as a reaction to poverty or a form of greed and avarice.1 Avarice has been seen as a part of the human condition and thus as a non-historical, that is, a quasi-anthropological constant. Anthropological constants hardly ever help to explain the behaviour of historical people. In our case, an alleged human tendency to accumulate material wealth does not explain why some people engaged in treasure hunting whereas others did not. Why did people look for treasure? Why did they talk about treasure? Why were they willing to suffer the repeated failure of treasure hunts and continue to look for hidden riches?

The cell—cell signaling gene CDH13 is associated with a wide spectrum of neuropsychiatric disorders, including attention-deficit/hyperactivity disorder (ADHD), autism, and major depression. CDH13 regulates axonal outgrowth and synapse formation, substantiating its relevance for neurodevelopmental processes. Several studies support the influence of CDH13 on personality traits, behavior, and executive functions. However, evidence for functional effects of common gene variation in the CDH13 gene in humans is sparse. Therefore, we tested for association of a functional intronic CDH13 SNP rs2199430 with ADHD in a sample of 998 adult patients and 884 healthy controls. The Big Five personality tra…

Uso problemático del smartphone: el papel de los Cinco Grandes, la Tríada Oscura y la impulsividad

2021

Abstract. Este estudio examinó las relaciones entre los rasgos de personalidad de los cinco grandes (extraversión, afabilidad, neuroticismo, responsabilidad y apertura a la experiencia), la tríada oscura (maquiavelismo, psicopatía y narcisismo), la impulsividad y el uso problemático del smartphone. Doscientos dos participantes (52.48% hombres), con edades comprendidas entre los 18 y los 58 años, completaron el Ten-Item Personality Inventory, la Smartphone Addiction Scale, el Dirty Dozen y la escala de impulsividad de Plutchik. Los análisis de correlación mostraron que el uso problemático del smartphone estaba significativamente asociado a la extraversión, el neuroticismo, la impulsividad y …

Unemployment, Personality Traits, and the Use of Facebook

2021

Different personality traits respond differently to unfavourable life situations. Unemployment can have several negative social, economic, and domestic consequences. Many people use social media for a variety of reasons. The aim of this study is to examine the way different personality traits respond to Facebook in the period of unemployment. Data was obtained from 3,002 unemployed respondents in Nigeria. The study used regression model to analyse the data. Among the five personality traits, results indicated that the relationship between neuroticism and online social support was negative. However, the relationship between online social support and satisfaction was positive. The study highl…

The role of personality and role engagement in work-family balance

2013

The relations between personality, role engagement, and a four-dimensional typology of work-family balance (WFB) were examined within a community-based sample (n = 213) derived from the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS). The typology was formed based on both work-family conflict (WFC) and enrichment (WFE) experiences. The profiles of personality and role engagement differentiated the four WFB types – Beneficial, Harmful, Active, and Passive types. The Beneficial type (low WFC, high WFE; 48.4%) was characterized by low neuroticism, high agreeableness and high conscientiousness. The opposite was observed for the Harmful type (high WFC, l…

Straining at work and its relationship with personality profiles and individual consequences in healthcare workers (HCWs)

2020

Straining is an attenuated form of mobbing, in which the continuity of vexatious actions is not driven by a discriminatory intent. With the objective of testing the possible moderating role of personality in the relationship between perceptions about straining at work and individual consequences, a correlational design research involved 374 healthcare workers (HCWs) from two Italian hospitals. The following questionnaires were administered: (1) Short Negative Acts Questionnaire (S-NAQ), to assess discriminative actions at work)

Work-family conflict and its relations to well-being: the role of personality as a moderating factor

2003

Contains fulltext : 63496.pdf (Publisher’s version ) (Closed access) The aim of the present study was to examine the role of the Big Five personality dimensions as possible moderating factors between two types of work–family conflicts: work interference with family (WIF); and family interference with work (FIW); and their relationship to well-being in the domains of work and family generally as well. The participants were fathers (n=296) who took part in a national family research project in the Netherlands in 1995. All fathers were employed full-time. The results showed that emotional stability moderated the relationships between WIF and job exhaustion and between WIF and depression. In ad…

Integrating Personality Structure, Personality Process, and Personality Development

2017

In this target article, we argue that personality processes, personality structure, and personality development have to be understood and investigated in integrated ways in order to provide comprehensive responses to the key questions of personality psychology. The psychological processes and mechanisms that explain concrete behaviour in concrete situations should provide explanation for patterns of variation across situations and individuals, for development over time as well as for structures observed in intra–individual and inter–individual differences. Personality structures, defined as patterns of covariation in behaviour, including thoughts and feelings, are results of those processe…
