The relationship between Big-5 personality traits and cognitive ability in older adults – a review

It is well established that fundamental aspects of cognition such as memory and speed of processing tend to decline with age; however, there is substantial between-individual variability in levels of cognitive performance in older adulthood and in rates of change in cognitive abilities over time. Recent years have seen an increasing number of studies concerned with examining personality characteristics as possible predictors of some of this variability in cognitive aging. The purpose of this article is to review the literature, and identify patterns of findings regarding the relationships between personality (focusing on the Big-5) and cognitive ability across nonclinical populations of older adults. Possible mechanisms underlying associations of personality characteristics with cognition are reviewed, and assessed in the context of the current literature. Some relatively consistent relationships are identified, including positive associations between openness and cognitive ability, and associations of conscientiousness with slower rates of cognitive decline. However, the relationships between several personality traits and cognitive abilities in older adults remain unclear. We suggest some approaches to research design and analysis that may help increase our understanding of how personality differences may contribute to cognitive aging.     

Preference or ability: Exploring the relations between risk preference,personality, and cognitive abilities

Key issues in the behavioral sciences are if there exist stable risk preferences that generalize across domains and if these are best measured by revealed risk preference (RRP) in behavioral decision tasks or by surveys eliciting stated risk preference (SRP). We applied network analysis to data from a representative Swedish sample to investigate the relations between RRP, SRP, personality characteristics, and cognitive abilities, using in total over 70 measurements. The results showed that different measures of RRP were poorly intercorrelated and formed a community together with measures of numerical and cognitive abilities. Measures of SRP were weakly correlated with measures of RRP and identified in a distinctly separate community, along with personality characteristics and gender. The ensuing analyses provided support for a model suggesting that RRPs are contaminated by demands on numerical and cognitive abilities. RRPs may thus suffer from poor construct validity, whereas SRPs may better capture people's everyday risk preferences because they are related to more stable traits.     

Adult age trends in the relations among cognitive abilities

Adult age (24 years to 91 years) was examined as a potential moderator of the relations among cognitive abilities in an aggregate dataset based on studies conducted at the Cognitive Aging Lab at the University of Virginia (N = 2,227). A novel approach was applied by which the manifestations of latent ability factors were free to differ across age groups, and age trends in the interrelations among the factors were tested. Contrary to the dedifferentiation hypothesis, there was no evidence for systematic increases in the magnitudes of relations among cognitive abilities. Conventional analytic procedures replicated these findings.     

Does the level at which cognitive change occurs change with age?

Increased age in adulthood is associated with systematically more negative cognitive change, but relatively little is known about the nature of change at different ages. The present study capitalized on the hierarchical structure of cognitive abilities to investigate possible age differences in the level at which change operates. Reductions in the longitudinal associations between test scores when across-time relations were specified at different levels in the hierarchical structure were used to infer contributions to change from the level of abilities and from the level of a general factor. Although the pattern of influences varied across different cognitive abilities, the results revealed little or no age differences in the relative contributions to change from different levels in the hierarchy.     

How general are the effects of trait anxiety and depressive symptoms on cognitive functioning?

A total of 3,781 healthy adults between 18 and 97 years of age completed trait anxiety and depressive symptoms inventories and also performed a battery of cognitive tests. Consistent with recent research on cognitive abilities, the cognitive variables could be organized into a hierarchical structure, with 5 first-order abilities and a single g-factor representing the variance common to the first-order abilities at the top of the hierarchy. Analyses were conducted to determine where in this hierarchy effects associated with trait anxiety and depressive symptoms were operating. The results indicated that trait anxiety and depressive symptoms had significant relations at the highest level in the hierarchy of cognitive abilities, but few relations of either characteristic were evident on the cognitive abilities, or on measures of working memory, after controlling influences at the g-factor level.

Exploring the Relations between Cattell–Horn–Carroll (CHC) Cognitive Abilities and Mathematics Achievement

As standardized measures of cognitive abilities and academic achievement continue to evolve, so do the relations between the constructs represented in these measures. A large, nationally representative sample of school‐aged children and youth between 6 and 19 years of age (N = 4,194) was used to systematically evaluate the relations between cognitive abilities and components of academic achievement in mathematics. The cognitive abilities of interest were those identified from the Cattell–Horn–Carroll model of intelligence. Specific areas of mathematics achievement included math calculation skills and math problem solving. Results suggest that fluid reasoning (Gf), comprehension‐knowledge (Gc), and processing speed (Gs) have the strongest and most consistent relations with mathematics achievement throughout the school years.Copyright © 2017 John Wiley & Sons, Ltd.

The Seattle Longitudinal Study: Relationship Between Personality and Cognition

This article reviews the history, measures and principal findings of the Seattle Longitudinal Study. This study began in 1956 focusing upon age differences and age changes in cognitive abilities. Its sampling frame is a large HMO in the Pacific Northwest. The study has been expanded to investigate various influences on cognitive aging including, cognitive styles, personality traits, life styles, and family environment. Current interest is also in the early detection of risk for dementia. In addition, this article reports original analyses of the relation of personality dimensions to cognitive abilities (both concurrent and longitudinal). While personality remains relatively stable over the adult life span, modest proportions of variance are shared between various personality traits and the cognitive abilities.     

Influence of cognitive abilities and age on word recall performance across trials and list segments

The influence of cognitive abilities and age on multitrial word recall performance was examined for different list segments (i.e., first, middle, and last) and across trials by having 2497 participants ages 18-98 complete a multitrial word list test along with reference cognitive ability tests. As expected, higher episodic memory ability was associated with better recall on all list segments but with a smaller influence for the last items on the early trials. Performance improved across trials, but there were no relations of the fluid intelligence construct that might be postulated to be associated with effective strategy implementation with any of the recall measures. Advanced age was associated with lower levels of performance, but very few of the age relations were significant after the variation in the reference cognitive abilities was controlled for.     

Do personality scale items function differently in people with high and low IQ?

Intelligence differences might contribute to true differences in personality traits. It is also possible that intelligence might contribute to differences in understanding and interpreting personality items. Previous studies have not distinguished clearly between these possibilities. Before it can be accepted that scale score differences actually reflect personality differences, personality items should show measurement invariance. The authors used item response theory to test measurement invariance in the five-factor model scales of the International Personality Item Pool (IPIP) and NEO-Five-Factor Inventory (NEO-FFI) across two groups of participants from the Lothian Birth Cohort 1936 with relatively low and high cognitive abilities. Each group consisted of 320 individuals, with equal numbers of men and women. The mean IQ difference of the groups was 21 points. It was found that the IPIP and NEO-FFI items were measurement invariant across all five scales, making it possible to conclude that any differences in IPIP and NEO-FFI scores between people with low and high cognitive abilities reflected personality trait differences.

Relations between the motor and cognitive dimensions of preschool girls and boys

The aim of this study was to compare relations between latent motor dimensions and cognitive abilities of preschool boys and girls (N=665, age: 5 to 6 years). The psychological part of the testing was implemented with the Test Razkol. For the assessment of motor abilities 28 tests were given. The associations of motor and cognitive variables were estimated by multiple regression analysis, which showed positive and significant associations between the latent motor variables and the cognitive variable for both boys and girls. On both sexes, the motor dimensions with the strongest associations with the cognitive abilities are those of coordination and the speed of movement. Despite some differences between boys and girls, they still have a lot in common since the most important latent motor dimensions prevailing in the connection between motor and cognitive dimensions are similar.     

Age-cognition relations and the personality trait of Conscientiousness

Increasing age has been found to correlate with a decrease in many cognitive abilities and an increase in the personality trait of Conscientiousness. The first goal of this study was to examine whether an age-related decline in cognitive abilities, in particular Fluid ability, accounts for the age-related increase in Conscientiousness. The second goal was to investigate whether the role of cognitive abilities in the relation between age and Conscientiousness is similar among people of different levels of education.Our results support the conclusion that the relation between age and Conscientiousness is mediated by fluid ability and working memory abilities, and that these effects are stronger in people with lower levels of education.Altogether, these findings are consistent with the hypothesis that age differences in characteristics such as persistence, self-motivation and dutifulness may help compensate for age differences in cognition.     

Out of sight,out of mind? Relations between visual acuity and cognition

Prior research has established significant relations between measures of sensory ability and cognitive function in adults of different ages, and several explanations for this relation have been proposed. One explanation is that sensory abilities restrict cognitive processing, a second is that cognitive abilities influence assessments of sensory ability, and a third is that both sensory function and cognition are affected by a common, potentially age-based, third factor. These explanations were investigated using mediation and moderation analyses, with near visual acuity as the sensory measure and scores on visual speed tests and auditory memory tests as the cognitive measures. Measures of visual acuity, speed, and memory were obtained from three moderately large samples, two cross-sectional (N?=?380, N?=?4,779) and one longitudinal (N?=?2,258), with participants ranging from 18 to 90 years of age. The visual acuity and cognitive measures had different age trajectories, and the visual acuity–cognition relations were similar in each 5-year age band. The results suggest that the age-related differences and changes in near visual acuity are unlikely to contribute to the age-related differences and changes in speed and memory measures.     

The relations between cognitive ability and personality: Convergent results across measures

Several studies have investigated the relations between cognitive ability and Big Five personality constructs. The present study extended previous research by (a) examining these relationships in large samples (total N = 120,014), (b) including several measures of cognitive ability and personality, (c) examining both domain and facet-level personality scores, (d) expanding the personality domains studied to include Machiavellianism, and (e) correcting the observed correlations for range restriction and reliability to provide a better statistical estimate of the relations between the cognitive and personality scores and constructs. Results were consistent with prior research showing a positive relationship between cognitive ability and Openness and negative relationships between cognitive ability and Neuroticism and Conscientiousness. Negative relations between cognitive ability and Extraversion and Agreeableness also were observed. Machiavellianism, not part of the Big Five was found to have a positive correlation with cognitive ability. Of particular interest was the finding that the relations between cognitive ability and personality were affected by the specific content of the cognitive and personality measures. Cognitive measures with verbal content were more strongly correlated with personality than were cognitive measures with math or nonverbal content for all of the samples. Also, there was considerable variability in the cognitive-personality correlations for the facets underlying each personality domain. The variability in correlations at the facet-level implies that cognitive-personality relationships at the domain-level will vary as a function of the specific content of the cognitive and personality measures. Overall, the results provide support for cognitive-personality association at the measurement level.     

Examining age differences in performance of a complex information search and retrieval task.

This study examined age differences in performance of a complex information search and retrieval task by using a simulated real-world task typical of those performed by customer service representatives. The study also investigated the influence of task experience and the relationships between cognitive abilities and task performance. One hundred seventeen participants from 3 age groups, younger (20-39 years). middle-aged (40-59 years), and older (60-75 years), performed the task for 3 days. Significant age differences were found for all measures of task performance with the exception of navigational efficiency and number of problems correctly navigated per attempt. There were also effects of task experience. The findings also indicated significant direct and indirect relations between component cognitive abilities and task performance.     

Personality,Interest, and Motivational Determinants of Maximal and Typical Performances on a Verbal Knowledge Task

The motivation constructs of Need for Cognition, Liking in Thinking, and Typical Intellectual Engagement, NEO Five-Factor Inventory factors, and RIASEC interests along with age were used to predict verbal tasks completed under timed (maximal performance) or untimed (typical performance) conditions. The results from a sample of 341 participants (245 female and 116 male), ranging in age from 18 to 71 years (M = 29.33, SD = 12.08), indicated that the men and women diverge in the relationships between their noncognitive domains and the verbal tasks. That is, women's verbal abilities are influenced by their age, and personality, interests, and motivations, whereas only personality and age contributed to verbal abilities in men. The results also displayed that the context in which a cognitive task is performed induced either maximal or typical efforts with different relationships with the predictor variables. The implications of the findings in relation to workplace training and development are discussed.     

Construct validity and age sensitivity of prospective memory

We administered four prospective memory tasks to 330 adults between 18 and 89 years of age to investigate the relationship among the measures of performance in the four tasks, as well as the relationship of the prospective memory measures to age, other cognitive abilities, and noncognitive factors. The four prospective memory variables were found to exhibit both convergent and discriminant validity, indicating that prospective memory ability appears to represent a distinct dimension of individual differences. The prospective memory construct was significantly related to other cognitive abilities, such as executive functioning, fluid intelligence, episodic memory, and perceptual speed, but it was only weakly related to self-ratings of (primarily retrospective) memory and to personality traits. Although a substantial proportion of the age-related variance on the prospective memory construct was shared with other cognitive abilities, we also found some evidence of unique, statistically independent, age-related influences on prospective memory.     

Une redéfinition des relations entre la personnalité « Ouverte à l’expérience » et l’intelligence

Previous investigations of the relations between the Big Five personality traits and cognitive abilities have consistently supported that higher levels of openness to experience are associated with higher levels of crystallized abilities or knowledge. However, consistent with the idea that crystallized abilities are the product of the exercise of fluid abilities in the past, a moderately strong correlation between both types of abilities is generally found. Then, the first purpose of the current project was to examine the role of fluid abilities in the relation between openness to experience and crystallized abilities. It aimed at determining whether the relation of openness to crystallized abilities was still significant after controlling for the specific contribution of fluid intelligence to crystallized abilities; or conversely, whether this relation was explained by the relation of openness to fluid intelligence. The second purpose was to determine if the relation of openness to experience to both fluid and crystallized abilities varied as a function of age. The possibility that openness to experience differentially contributes to the variance in fluid and crystallized abilities as a function of age was examined. One hundred and sixty-four participants, aged 18 to 96, completed the openness to experience scale (French version of the IPIP, Goldberg, 1999. Personality psychology in Europe), in addition to several tests of fluid and crystallized abilities. After controlling for the variance associated with fluid abilities in crystallized abilities, Openness to experience was not related to crystallized abilities anymore. Moreover, the contribution of the personality trait of Openness to the variation in fluid and crystallized intelligences was similar at different ages in adulthood. Several possible interpretations and their respective implications are discussed. First, people more open may exercise fluid abilities more than people who are less open, and then increase the efficiency of these abilities. Second, fluid abilities may influence the development of the personality trait of openness to experience, that is people's tendency to seek out for novelty and curiosity. And third, the openness to experience scale may only reflect people's self-assessments of their abilities, such as a self-assessed intelligence construct. In any case, our results strongly suggest that the openness-cognition relation reflects something different from a relation between activity and knowledge acquisition.
