Nonlinear blood pressure effects on cognition in old age: separating between-person and within-person associations

Midlife hypertension is associated with increased risk of cognitive impairment in later life. The association between blood pressure (BP) in older ages and cognition is less clear. In this study we provide estimates of between-person and within-person associations of BP and cognition in a population-based sample (N = 382) followed from age 70 across 12 occasions over 30 years. Between-person associations refer to how individual differences in BP relates to individual differences in cognition. Within-person associations refer to how individual and time specific changes in BP relate to variation in cognition. Hierarchical linear models were fitted to data from three cognitive measurements (verbal ability, spatial ability, and perceptual speed) while accounting for demographic and health-related covariates. We found consistent nonlinear between-person associations between diastolic BP (DBP) and cognition, such that both low (<75 mmHg) and high (>95 mmHg) pressure were associated with poorer cognition. Within-person decreases in systolic BP (SBP) and DBP were associated with decreases in perceptual speed. Notably, between-person and within-person estimates did not reveal similar associations, suggesting the need to separate the two effects in the analysis of associations between BP and cognition in old age.     

Social participation attenuates decline in perceptual speed in old and very old age

Does an engaged and active lifestyle in old age alleviate cognitive decline, does high cognitive functioning in old age increase the possibility of maintaining an engaged and active lifestyle, or both? The authors approach this conundrum by applying a structural equation model for testing dynamic hypotheses, the dual change score model (J. J. McArdle & F. Hamagami, 2001), to 3-occasion longitudinal data from the Berlin Aging Study (Time 1: n=516, age range=70-103 years). Results reveal that within a bivariate system of perceptual speed and social participation, with age and sociobiographical status as covariates, prior scores of social participation influence subsequent changes in perceptual speed, while the opposite does not hold. Results support the hypothesis that an engaged and active lifestyle in old and very old age may alleviate decline in perceptual speed.     

Personality similarity,perceptual accuracy,and relationship satisfaction in dating and married couples

The association between actual and perceptual personality similarity and perceptual accuracy on relationship satisfaction is examined in 191 couples. Self‐ and partner ratings of personality were assessed using the Revised NEO Personality Inventory ( P. T. Costa & R. R. McCrae, 1992 ) and relationship satisfaction using the Relationship Assessment Scale ( S. S. Hendrick, A. Dicke, & C. Hendrick, 1998 ). Actual and perceptual similarity and perceptual accuracy were quantified using the index of profile agreement (R. R. McCrae, 1993 ) and L. J. Cronbach and G. C. Gleser's (1953) D‐indices. These indices showed large variability in personality profiles within couples and considerable perceptual accuracy between raters. Actual similarity was positively associated with female relationship satisfaction, controlling for personality traits of both partners. Moreover, partial support was obtained for the positive associations between perceptual similarity and accuracy and relationship satisfaction.     

Differential Relationships of Hedonic and Eudaimonic Well-Being with Self-Control and Long-Term Orientation1

This study sought to explore differential relations between the hedonic (life satisfaction, negative affect, and positive affect) and eudaimonic (psychological well-being and social well-being) components of well-being and five criterion variables: long-term planning, self-control, sensation-seeking, grit, and intellectualism. The study used a sample of 1,310 Korean adults (M_age = 40.024 years, SD_age = 10.922 years). It was predicted and found that the criterion variables of the study had stronger associations with eudaimonic well-being than hedonic well-being. The results indicate that eudaimonic well-being is more consistent than hedonic well-being with a long-term emphasis on skill-building and striving for future goals (as opposed to immediate gratification).     

Perceptual speed in adulthood: cross-sectional and longitudinal studies

Cross-sectional data on age differences in perceptual speed are presented from the Seattle Longitudinal Study for the age range 22-91 years (N = 1,620, first assessed in 1977; N = 628, first assessed in 1984). In addition, 838 subjects were followed over the 7-year interval. Markers of perceptual speed were the Identical Pictures and Finding A's tests from the ETS Kit of Factor-Referenced Tests. Significant age differences, age changes, and cohort differences were found at both observed variable and latent construct levels. Cross-lagged correlations examine the role of perceptual speed in predicting later performance on other abilities (Verbal Meaning, Inductive Reasoning, Spatial Orientation, Number, and Word Fluency). When perceptual speed is partialled out of scores for these abilities, aging effects are reduced markedly for all abilities, but least for Spatial Orientation and Inductive Reasoning.     

Impulsivity and Sensation Seeking: Differing Associations with Psychological Well-Being

Sensation seeking and lack of inhibition are often discussed as risk factors for hazardous and maladaptive behavior, particularly during the transition into adulthood. However, some degree and types of novelty-seeking and exploration may also be adaptive and conducive to psychological well-being. The current study examines associations between sensation seeking, impulsivity, and well-being in a large US adult sample (n = 1399, mean age = 36.2 years, range: 18–78). As conceptualized by the UPPS-P model (Whiteside and Lynam, Personality and Individual Differences, 30(4), 669-689, 2001), sensation seeking (pursuit of stimulation) was distinguished from other forms of impulsivity (lack of inhibition) by having a positive association with psychological well-being, eudaimonic well-being, and mental health status. Those positive relations were stronger for younger adults compared to older adults. Negative urgency, lack of perseverance, lack of premeditation, and positive urgency all held either negative or null associations with well-being. Findings indicate that sensation seeking has positive associations with psychological and eudaimonic well-being, in contrast to other elements of impulsivity, and particularly among younger adults.

     

Midazolam amnesia and conceptual processing in implicit memory

Prominent theories of implicit memory (D. Schacter, B. Church, & J. Treadwell, 1994) emphasize the dominant role of perceptual processing in mediating priming on perceptual implicit memory tests. Examinations of the effects of conceptual processing on perceptual implicit memory tests have produced ambiguous results. Although a number of investigations (e.g., J. Toth & R. Hunt, 1990) have demonstrated that variations in conceptual processing affect priming on perceptual implicit memory tests, these effects may arise because of the contaminating effects of explicit memory. The current experiment examined this controversy using midazolam, a benzodiazepine that produces a dense, albeit temporary, anterograde amnesia when injected prior to study. The experiment examined whether the effects of generation found on the implicit memory test of perceptual identification were affected by a midazolam injection prior to study. Results demonstrated that midazolam substantially diminished generation effects in free and cued recall, as well as overall performance on these tests, but had no detectable effect on the generation effect in perceptual identification.     

Age-based structural dynamics between perceptual speed and knowledge in the Berlin Aging Study: direct evidence for ability dedifferentiation in old age

According to 2-component theories of intelligence, negative cross-sectional age gradients in mechanic (broad Gf) and pragmatic (broad Gc) cognitive components reflect the increasing constraining of the former in the expression and integrity of the latter component. The authors examined this widely held but untested assumption by applying a recently proposed dynamic structural modeling technique, the bivariate dual change score model, to longitudinal data from the Berlin Aging Study (N = 516, age range = 70-103 years). Mechanics and pragmatics were indexed by perceptual speed and knowledge, respectively. As hypothesized, results indicated that changes in knowledge are dominated by perceptual speed and offered strong support for the notion of "mechanization" of pragmatic abilities in old and very old age.     

Trajectories of emotional well-being in mothers of adolescents and adults with autism

Raising an adolescent or adult child with a developmental disability confers exceptional caregiving challenges on parents. We examined trajectories of 2 indicators of emotional well-being (depressive symptoms and anxiety) in a sample of primarily Caucasian mothers (N = 379; M age = 51.22 years at Time 1) of adolescent and adult children with an autism spectrum disorder (ASD; M age = 21.91 years at Time 1, 73.2% male). We also investigated within-person associations of child context time-varying covariates (autism symptoms, behavior problems, residential status) and maternal context time-varying covariates (social support network size and stressful family events) with the trajectories of emotional well-being. Data were collected on 5 occasions across a 10-year period. Average patterns of stable (depressive symptoms) and improved (anxiety) emotional well-being were evident, and well-being trajectories were sensitive to fluctuations in both child and maternal context variables. On occasions when behavior problems were higher, depressive symptoms and anxiety were higher. On occasions after which the grown child moved out of the family home, anxiety was lower. Anxiety was higher on occasions when social support networks were smaller and when more stressful life events were experienced. These results have implications for midlife and aging families of children with an ASD and those who provide services to these families.     

Examination of the processing speed account in a population-based longitudinal study with narrow age cohort design

The processing speed account suggests that general slowing of mental processing speed results in an overall decline, especially age-related decline, in other cognitive domains. Support for the speed account comes mainly from cross-sectional studies with participants that vary in age (age-heterogeneous samples). This study investigated how well variations in processing speed predict change of episodic recall in a longitudinal framework and examined with the Narrow Age Cohort (NAC) design. Data were obtained from Betula, a population-based longitudinal study. Both 5-year (n= 490; Time 3 - Time 4) and 10-year follow-up results (n= 608; Time 1 - Time 3) were used. In both samples, which were subjected to prospective dementia screening, we found considerably weaker associations in longitudinal data compared to cross-sectional, and also weaker associations in age-homogeneous than in age-heterogeneous samples. The results provide little support for the speed account.     

Academic optimistic bias: Implications for college student performance and well-being

Although optimism has several benefits, there are potential drawbacks associated with “too much of a good thing”. Within an academic context, a possible determinant of the adaptiveness of optimistic bias is whether students have a sense of control over academic outcomes: optimistically-biased (OB) achievement expectations paired with perceptions of academic control may enhance performance and well-being; optimistic bias in the absence of perceived control may result in disappointment, poor performance, and diminished well-being. The current longitudinal study examined academic control cognitions (ACC) among OB college students (n = 319) versus non-optimistically biased (non-OB) students (n = 321). We also examined the effects of academic optimistic bias on composite measures of college performance (perceived success, final psychology course grades, cumulative GPA, course attrition) and well-being (positive and negative emotions, health behaviors, future optimism) 6 months later; and determined whether ACC accounted for those associations. Significant MANCOVAs showed OB students had greater ACC, better subsequent well-being, and outperformed their non-OB counterparts. These well-being and performance differences remained significant after statistically accounting for initial aptitude and ACC. Overall, academic optimistic bias was accompanied by perceived controllability over scholastic outcomes, yet beyond the effects of ACC, optimistic bias was associated with better year-end performance and well-being. Findings have implications for maximizing the successful transition of first-year college students.     

Curiosity and well-being

Recent conceptualizations of curiosity have identified two underlying factors that together represent trait curiosity: exploration (the disposition to seek out novel/challenging situations) and absorption (the disposition to become fully engaged in these interesting situations) (Kashdan, Rose, & Fincham, 2004). These factors have been proposed to broaden the thought–action repertoire by promoting interest in novel/challenging situations and to incrementally build knowledge and well-being in a manner consistent with the Broaden-and-Build Theory (Fredrickson, B. L., 1998). This article reports findings from a study which examined associations between the exploration and absorption components of curiosity and continuous and categorical indices of well-being. Replicating and extending previous findings, the exploration (more so than absorption) component of curiosity exhibited moderate positive associations with measures of well-being. Implications and suggestions for future research are discussed.     

Evidence of Associations Between Lay Conceptions of Well-Being, Conception-Congruent Behavior, and Experienced Well-Being

Individuals’ lay conceptions of well-being have been found to be associated with several indexes of positive psychological functioning, yet little is known about the mechanisms underlying these associations. In two studies, the current research examined whether conception-congruent behavior mediates associations between conceptions of well-being and two indexes of experienced well-being (subjective well-being and meaning in life). Study 1 addressed the above question using a prospective approach, whereby associations between conceptions of well-being, predicted engagement in hedonic and eudaimonic behavior, and predicted well-being were examined. Study 2 more directly addressed the above question using a daily diary approach, whereby conceptions of well-being, actual engagement in hedonic and eudaimonic behavior, and experienced well-being were assessed over a period of 1 week. In both studies, results indicated that associations between eudaimonic conception dimensions and experienced well-being were partially mediated by engagement in eudaimonic behavior. Hedonic conception dimensions were largely unrelated to hedonic behavior and well-being. The current findings thus suggest that eudaimonic behavior is one potential route through which eudaimonic conception dimensions exert their salubrious effects on well-being.     

Gratitude,Social Cognition,and Well-Being in Emerging Adolescents

The authors explored Canadian emerging adolescents' social and moral reasoning skills (empathy, theory of mind), and their perceptions of gratitude, self-competencies, and well-being (spiritual, emotional). As part of a larger five-year longitudinal study, the authors describe results of Year 2 (2016–2017) data from 46 ninth-grade students (33 girls; M_age?=?13.5?years, SD?=?5.436 years) from eight schools (Ontario, Canada). Students’ perceptions of gratitude, spirituality, self-compassion, competencies, and well-being were measured by self-report questionnaires. Significant positive correlations were found among adolescents’ perceptions of gratitude, self-competencies, and emotional and spiritual well-being. Differently valenced patterns of associations were found among students’ perceptions of gratitude (appreciation for others and sense of abundance), self-compassion, and existential well-being, and spiritual comfort, and omnipresence. Simple appreciation was the only aspect of gratitude to show significant positive relations with religious well-being. Significant positive correlations were found between gratitude (sense of abundance) and self-compassion, whereas significant negative correlations were found between self-compassion and empathy, theory of mind, existential well-being, and religious well-being. Implications for theory and educational applications are discussed.     

Affective Well-Being in Retirement: The Influence of Values,Money, and Health Across Three Years

In this study, personal values, health, and financial status were investigated as determinants of affective well-being in a sample of 371 recent retirees across 3 years. Personal values, measured with the Portrait Value Questionnaire (Schwartz et al. in J Cross Cult Psychol 32:519–542, 2001), were hypothesized to show direct links to positive affect (PA) and negative affect (NA) as well as to moderate the association between financial and health status and affective well-being. Using structural equation modeling, higher PA was predicted by female gender, better finances, fewer illnesses, and higher self-transcendence (ST), openness to change (OC), and conservation values. Higher NA was predicted by female gender, lower finances, more illnesses, higher self-enhancement (SE) and lower OC values. SE and OC values also moderated the association between financial status and PA. Longitudinal analyses indicated a relatively stable pattern of associations across 3 years. While the impact of finances on affect was stable over time, the effects of health and values increased across 3 years.     

The Associations of Greek and Religious Organization Participation with College Students' Social Well-Being and Purpose

Two online-survey studies examined the associations of Greek (i.e., sorority and fraternity) and religious (i.e., church or campus ministry) organization participation with college students' social well-being and sense of purpose. In study 1 (N = 281), religious organization membership (versus no membership) was associated with connectedness and purpose, but for Greek organizations the associations held only with respect to level of organization involvement. In study 2 (N = 426), Greek and religious organization membership were both associated with most social well-being and purpose indicators, but only Greek membership was linked to lower loneliness. As in study 1, level of involvement in Greek, but not religious, organizations was linked to social well-being. Hypothesized moderators of the associations between organization membership and the purpose and social well-being variables were not supported. We discuss implications for professionals who work with college students to promote well-being, and we present future research ideas.     

Long-term antecedents and outcomes of perceived control

Perceived control plays an important role in shaping development throughout adulthood and old age. Using data from the adult lifespan sample of the national German Socio-Economic Panel (SOEP; N > 10,000, covering 25 years of measurement), we explored long-term antecedents, correlates, and outcomes of perceived control and examined if associations differ with age. Targeting correlates and antecedents of control, findings indicated that higher concurrent levels of social participation, life satisfaction, and self-rated health as well as more positive changes in social participation over the preceding 11 years were each predictive of between-person differences in perceived control. Targeting health outcomes of control, survival analyses revealed that perceived control predicted 14-year hazard ratio for disability (n = 996 became disabled) and mortality (n = 1,382 died). The effect for mortality, but not for disability, was independent of sociodemographic and psychosocial factors. Overall, we found very limited support for age-differential associations. Our results provide further impetus to thoroughly examine processes involved in antecedent-consequent relations among perceived control, facets of social life, well-being, and health.     

Identity configurations and well-being during normative cultural conflict: The roles of multiculturals’ conflict management strategies and academic stage

Multiculturals encounter normative cultural conflicts (intrapersonal conflicts between their cultures’ norms). Yet, no research has examined how these conflicts are managed, nor their antecedents and repercussions. This article examined how these conflicts are managed using two sets of conflict management strategies (active and agreeable) and tested whether they mediate the associations between identity configurations and well-being. Also, as the benefits of having integrated selves typically increase in later life stages, this article examined whether the associations between identity configurations and well-being differ between earlier (pre-university) and later academic stages (university). In Study 1 (N = 235), active strategies mediated the link between identity integration and well-being, whereas agreeable strategies mediated the link between compartmentalization and ill-being. In Study 2 (N = 241), these results were replicated. Study 2 further showed that the association between identity integration and well-being was stronger among university than pre-university students. Implications of these results are discussed.     

Your personality on a good day: How trait and state personality predict daily well-being

The dynamic mediation model (Wilt, Noftle, Fleeson, & Spain, 2012) explains the associations between personality traits and happiness through links between personality states and daily well-being. To test this model, and the mediators of these relations, we examined if between- and within-person variation in personality was associated with daily well-being for undergraduates (N = 133) and US adults (N = 117). The model explained the trait neuroticism and daily well-being association. Also, after controlling for traits, people were happier on days in which they were extraverted, agreeable, conscientious, emotionally stable, and open to experience. Finally, these associations were partially mediated by the satisfaction of daily psychological needs. We discuss how the operationalization of state extraversion might impact its relation with daily well-being.     

Well-being and Substance Use in Emerging Adulthood: The Role of Individual and Family Factors in Childhood and Adolescence

The present study examined the long-term impact of individual and family factors during childhood and adolescence on outcomes associated with the transition to adulthood, specifically well-being and substance use. Data for this study were drawn from the Child Development Supplement (CDS) and Transition to Adulthood (TA) surveys (n?=?1362), both a part of The Panel Study of Income Dynamics (PSID). We first examined the influence of individual and family factors from childhood and adolescence on well-being and substance use during the transition to adulthood using Structural Equation Modeling (SEM). We then applied a mixture modeling approach to evaluate whether there were subgroups (latent classes) in these transitions to adulthood outcomes, and how these subgroups linked with the individual and family factors from younger years. We found that, in general, parental acceptance and psychological control in childhood and adolescence predicted all aspects of well-being during the transition to adulthood. Substance use during this transition was linked with being male, White, and heightened parental psychological control. Overall, observable differential associations between individual and family factors during childhood and adolescence and outcomes in later life highlighted a need to evaluate transitional aspects independently, rather than grouping young adults all together.
