Neuropsychiatric symptoms predict rate of change in executive function in Alzheimer's disease and related dementias.

Objective: Neuropsychiatric symptoms (NPS) are considered diagnostic and prognostic indicators of dementia and are attributable to neurodegenerative processes. Little is known about the prognostic value of early NPS on executive functioning (EF) decline in Alzheimer's disease and related dementias (ADRD). We examined whether baseline NPS predicted the rate of executive function (EF) decline among older adults with ADRD.

Supporting the status quo is weakly associated with subjective well-being: A comparison of the palliative function of ideology across social status groups using a meta-analytic approach.

Research has suggested that the endorsement of ideologies supporting the status quo leads to higher subjective psychological well-being-an idea labeled as the palliative function of ideology within system justification theory. Furthermore, this approach has suggested that this association should be moderated by social status. Specifically, the association between the endorsement of ideologies supporting the status quo and well-being should be positive among high-status groups and negative among low-status groups-mainly as a function of the existence of a unique motivation to justify the status quo.

Basic or Adaptation: The Assessment and Heritability of a Brief Measure of Agency.

The interpersonal circumplex describes two major axes of personality that guide much of social behavior. Agency, one half of the interpersonal circumplex, refers to relatively stable behavioral patterns that center on self-focused dominance and assertiveness. Past empirical work on agency tends to treat the dimension as a characteristic adaptation, rather than a basic component of personality, in part due to the relatively large gender difference in agency with masculine individuals tending to behave more agentic.

Testing the temporal precedence of family functioning and child psychopathology in the LONGSCAN sample.

Family functioning may serve as protective or risk factors in the development of youth psychopathology. However, few studies have examined the potentially reciprocal relation between child psychopathology and family functioning. To fill this gap in the literature, this study tested for time-ordered associations between measures of family functioning (e.

Job characteristics and personality change in young adulthood: A 12-year longitudinal study and replication.

Objective: Personality changes are related to successfully performing adult occupational roles which require teamwork, duty, and managing stress. However, it is unclear how personality development relates to specific job characteristics that vary across occupations.

Method: We investigated whether 151 objective job characteristics, derived from the Occupational Information Network (O*NET), were associated with personality levels and changes in a 12-year longitudinal sample followed over the school to work transition.

Life events sometimes alter the trajectory of personality development: Effect sizes for 25 life events estimated using a large, frequently assessed sample.

Objective: Personality changes across the life span. Life events, such as marriage, becoming a parent, and retirement, have been proposed as facilitating personality growth via the adoption of novel social roles. However, empirical evidence linking life events with personality development is sparse.

Triangulating causality between childhood obesity and neurobehavior: Behavioral genetic and longitudinal evidence.

Childhood obesity is a serious health concern that is not yet fully understood. Previous research has linked obesity with neurobehavioral factors such as behavior, cognition, and brain morphology. The causal directions of these relationships remain mostly untested.

Association of Wealth With Longevity in US Adults at Midlife.

Importance: Wealthy adults tend to live longer than those with less wealth. However, a challenge in this area of research has been the reduction of potential confounding by factors associated with the early environment and heritable traits, which could simultaneously affect socioeconomic circumstances in adulthood and health across the life course.

Objective: To identify the association between net worth at midlife and subsequent all-cause mortality in individuals as well as within siblings and twin pairs.

Personality stability and change: A meta-analysis of longitudinal studies.

Past research syntheses provided evidence that personality traits are both stable and changeable throughout the life span. However, early meta-analytic estimates were constrained by a relatively small universe of longitudinal studies, many of which tracked personality traits in small samples over moderate time periods using measures that were only loosely related to contemporary trait models such as the Big Five. Since then, hundreds of new studies have emerged allowing for more precise estimates of personality trait stability and change across the life span.

Testing the factor structure and measurement invariance of the Temporal Experience of Pleasure Scale in adolescents across time, gender, and race/ethnicity.

The Temporal Experience of Pleasure Scale (TEPS) is a self-report measure designed to assess anticipatory and consummatory pleasure, two facets of anhedonic predispositions. Despite its widespread use, the factor structure of the TEPS has yet to be tested in adolescents, who are at increased risk for psychopathology and undergoing rapid changes in reward-related processes. In response, the present study aimed to test the factor structure and measurement invariance of the TEPS across time, gender, and race/ethnicity in a diverse adolescent sample.

Genetic and Environmental Factors of Non-Ability-Based Confidence.

Non-ability-based confidence is confidence in one's ability that is not calibrated to actual ability. Here, we examine what psychological factors are associated with possessing more or less confidence relative to one's ability and to what extent genetic and environmental processes contribute to these links. Using data from the Texas Twin Project ( = 1,588 participants, aged 7-15 years), we apply a latent variable residual approach to calculate non-ability-based confidence as self-rated confidence net of ability on standardized cognitive tests.

Two genetic analyses to elucidate causality between body mass index and personality.

Background/objectives: Many personality traits correlate with BMI, but the existence and direction of causal links between them are unclear. If personality influences BMI, knowing this causal direction could inform weight management strategies. Knowing that BMI instead influences personality would contribute to a better understanding of the mechanisms of personality development and the possible psychological effects of weight change.

Geographic Variation in Personality is Associated With Fertility Across the United States.

Levels of fertility and the shape of the age-specific fertility schedule vary substantially across U.S. regions with some states having peak fertility relatively early and others relatively late.

Adolescent Big Five personality and pubertal development: Pubertal hormone concentrations and self-reported pubertal status.

In early adolescence, levels of conscientiousness and agreeableness have been found to temporarily decrease, with levels of neuroticism increasing, indicating a dip in personality maturation. It is unknown whether these changes are related to the process of puberty, a major developmental milestone with numerous changes for children. Here, we first replicated the dip in personality maturity in early adolescence ( = 2640, age range 8-18, 51% girls, 65% non-Hispanic white, 21% Hispanic/Latino, 10% African American, 9% other, roughly 33% of families received means-tested public assistance) and tested associations between the Big Five personality dimensions and pubertal development and timing across late childhood and adolescence ( = 1793).

Childhood growth in math and reading differentially predicts adolescent non-ability-based confidence: An examination in the SECCYD.

Non-ability-based confidence is one of the most pervasive human psychological biases. It is a part of a family of confidence judgments, including overconfidence and metacognitive calibration accuracy, defined by a discrepancy between self-perception of ability and actual ability. Across many domains, most people exhibit some degree of miscalibration in their confidence.

Personality Changes Predict Early Career Outcomes: Discovery and Replication in 12-Year Longitudinal Studies.

In this research, we examined whether personality changes from adolescence to young adulthood predicted five early career outcomes: degree attainment, income, occupational prestige, career satisfaction, and job satisfaction. The study used two representative samples of Icelandic youth (Sample 1: = 485, Sample 2: = 1,290) and measured personality traits over 12 years (ages ~17 to 29 years). Results revealed that certain patterns of personality growth predicted career outcomes over and above adolescent trait levels and crystallized ability.

Weak and uneven associations of home, neighborhood, and school environments with stress hormone output across multiple timescales.

The progression of lifelong trajectories of socioeconomic inequalities in health and mortality begins in childhood. Dysregulation in cortisol, a stress hormone that is the primary output of the hypothalamus-pituitary-adrenal (HPA) axis, has been hypothesized to be a mechanism for how early environmental adversity compromises health. However, despite the popularity of cortisol as a biomarker for stress and adversity, little is known about whether cortisol output differs in children being raised in socioeconomically disadvantaged environments.

Endovascular treatment of patients with high-risk symptomatic intracranial vertebrobasilar stenoses: long - term outcomes.

Background And Purpose: We present the long-term outcome after endovascular treatment of symptomatic intracranial posterior circulation stenoses.

Methods: 30 patients with symptomatic intracranial posterior circulation stenoses exceeding 70% underwent endovascular treatment between 2006 and 2012. Data regarding presentation, follow-up, procedure details, complications and imaging follow-up were reviewed.

The price of good welfare: Does informing consumers about what on-package labels mean for animal welfare influence their purchase intentions?

Public concern for farm animal welfare is growing. However, high welfare purchases require consumers to make sense of often confusing labels. This study aims to investigate consumers' preferences for higher welfare products with on-package animal welfare labels and to explore whether providing consumers with detailed information about the welfare conditions behind on-package animal welfare labels could have a positive influence on farm animal welfare.

Genetic and Environmental Associations Between Child Personality and Parenting.

Parenting is often conceptualized in terms of its effects on offspring. However, children may also play an active role in influencing the parenting they receive. Simple correlations between parenting and child outcomes may be due to parent-to-child causation, child-to-parent causation, or some combination of the two.

Genetic overlap between executive functions and BMI in childhood.

Background: Executive functions (EFs) comprise a group of cognitive processes that selectively control and regulate attention. Inverse relations have been reported between EFs and BMI. However, the mechanisms underlying this association are not well understood.

National Gross Domestic Product, Science Interest, and Science Achievement: A Direct Replication and Extension of the Tucker-Drob, Cheung, and Briley (2014) Study.

We replicated the study by Tucker-Drob, Cheung, and Briley (2014), who found that the association between science interest and science knowledge depended on economic resources at the family, school, and national levels, using data from the 2006 Programme for International Student Assessment (PISA). In more economically prosperous families, schools, and nations, student interest was more strongly correlated with actual knowledge. Here, we investigated whether these results still held despite substantial changes to educational and economic systems over roughly a decade.
