In this study, we evaluated birth cohort (i.e., generational) differences in the onset and rate of acceleration in cognitive decline prior to death (i.e., terminal decline [TD]). We obtained data from two cohorts, born in 1901-1902 (n = 755, 64% females) and 1930 (n = 347, 48% females), identified and sampled at age 70 from the same city population and assessed on the same cognitive tests at ages 70, 75, 79, 85, and 88. The 1901-1902 cohort was additionally assessed at ages 90, 92, 95, 97, 99, and 100. The outcome was defined at each measurement occasion by a composite score of three cognitive tests assessing spatial ability, perceptual and motor speed, and reasoning. Date of death was obtained from population register, with the last update in April 2023, covering over 99% and 38% of the cohort members, respectively. We fitted a random TD change point model to the data while accounting for sex and education. Findings revealed expected TD onset (as conditioned on male with formal education) 5.17 (95% highest density interval [2.54, 8.05]) years prior to death in the 1901-1902 cohort, with an acceleration in rate of decline by a factor of 4.43 within the TD phase. This estimate was delayed by 2.53 (95% highest density interval [5.68, 0.10]) years in the 1930 cohort, with an acceleration by a factor of 5.16 within the TD phase. To the best of our knowledge, this is the first study to present evidence indicating that today's birth cohort experience, on average, a shorter TD phase in comparison to earlier born cohorts.

Older adults may experience certain forms of cognitive decline, but some forms of semantic memory remain intact in older age. To address how metaphor comprehension changes with age and whether metaphor comprehension relies more heavily on analogical reasoning (supported by fluid intelligence) or on conceptual combination (supported by crystalized intelligence), we compared performance of younger and older adults. In two experiments, healthy older adults (54-88 years) scored lower on a measure of fluid intelligence (Ravens Progressive Matrices) but higher on a measure of crystalized intelligence (Mill Hill Vocabulary Test) relative to younger adults (18-34 years). Groups were equally successful in comprehending relatively easy metaphors (Study 1), but older adults showed a striking advantage over younger adults for novel literary metaphors (Study 2). Mixed-effects modeling showed that measures of fluid and crystalized intelligence each made separable contributions to metaphor comprehension for both groups, but older adults relied more on crystalized intelligence than did younger adults. These age-related dissociations clarify cognitive effects of aging and highlight the importance of crystalized intelligence for metaphor comprehension in both younger and older adults.

The article explores personal values among older adults in relation to their "offspring status." Erikson's theory of psychosocial development and Schwartz's theory of human values suggest a positive relationship between having offspring and prosocial values. We tested this hypothesis by comparing older adults who have none, one, or two generations of descendants: childless (with no descendants), grandchildless (with adult children and no grandchildren), and grandparents. We conducted a hierarchical multilevel regression analysis using data from Round 9 of the European Social Survey on a subsample of 12,713 respondents older than 65 from 29 European countries. Our model predicted preferences for four of the Schwartz higher order value types (Self-Transcendence, Self-Enhancement, Openness to Change, and Conservation) among the three categories of older adults based on their offspring status, controlling for individual-level (gender, education level, general health) and macro-level variables (Human Development Index). All but Openness to Change values are significantly predicted by older adults' offspring status. Having grandchildren is positively associated with Self-Transcendence and Conservation values (socially oriented values) and negatively with Self-Enhancement (values with self-oriented focus). The article discusses the theoretical implications of the obtained findings, focusing on plausible mechanisms connecting the offspring status and value orientations.

Existing research shows a clear link between the way people experience the aging process (i.e., self-perceptions of aging) and their health, cognitive abilities, and well-being. In contrast, there is little research on the association between self-perceptions of aging and social functioning. This study examines the relationship between awareness of age-related gains and losses as two facets of self-perceptions of aging and social approach and avoidance goals. Social approach goals (i.e., goals that focus on positive, desirable social outcomes) and social avoidance goals (i.e., goals that focus on negative, undesirable social outcomes) play a fundamental role in shaping individuals' social experiences and behaviors. We hypothesize that awareness of age-related gains is associated with social approach goals, whereas awareness of age-related losses is associated with social avoidance goals. In an experience sampling study with N = 117 participants aged 18-85 years (M = 40.4, SD = 17.1), we examined interindividual differences in participants' awareness of age-related gains and losses and how these relate to social goals. We focused on social goals in everyday social situations (aggregated state) and as individual dispositions (trait). As hypothesized, awareness of age-related gains was positively associated with social approach (but not avoidance) goals, while awareness of age-related losses was positively associated with social avoidance (but not approach) goals. These associations largely persisted even after controlling for age. These findings suggest that perceptions of age-related gains and losses are important factors in how people navigate their social lives. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

While there is strong evidence that younger adults use contextual information to generate semantic predictions, findings from older adults are less clear. Age affects cognition in a variety of different ways that may impact prediction mechanisms; while the efficiency of memory systems and processing speed decrease, life experience leads to complementary increases in vocabulary size, real-world knowledge, and even inhibitory control. Using the visual world paradigm, we tested prediction in younger (n = 30, between 18 and 35 years of age) and older adults (n = 30, between 53 and 78 years of age). Importantly, we differentiated early stage predictions based on simple spreading activation from the more resource-intensive tailoring of predictions when additional constraining information is provided. We found that older adults were slower than younger adults in generating early stage predictions but then quicker than younger adults to tailor those predictions given additional information. This suggests that while age may lead to delays in first activating relevant lexical items when listening to speech, increased linguistic experience nonetheless increases the efficiency with which contextual information is used. These findings are consistent with reports of age having positive as well as negative impacts on cognition and suggest conflation of different stages of prediction as a basis for the inconsistency in the aging-related literature to date.

The Socioemotional Selectivity Theory (SST) posits that older and younger adults have different life goals due to differences in perceived remaining lifetime. Younger adults focus more on future-oriented knowledge exploration and forming new friendships, while older adults prioritize present-focused emotional regulation and maintaining close relationships. While previous research has found these age differences manifest in autobiographical textual expressions, their presence in verbal communication remains unexplored. We recruited 36 older adults and 36 younger adults to form 12 younger adults-younger adults dyads, 12 older adults-older adults dyads, and 12 younger adults-older adults dyads engaging in three conversational scenarios. Analysis of communication transcripts using Linguistic Inquiry and Word Count revealed that in intragenerational communication, older adults used more present-focused and family-related words, and fewer future-focused, negative emotion, and knowledge acquisition words compared to younger adults, aligning with SST predictions. However, in intergenerational communication, younger and older adults showed similar patterns in future-focused, cognitive, and family-related language use. This suggests that participants adjusted their goal orientations to accommodate each other, mitigating the age differences proposed by SST and partially supporting the Interpersonal Cognitive Consistency Model. These findings indicate that while SST explains semantic expressions in intragenerational communication, group dynamics toward verbal consistency play a more vital role in intergenerational communication.

Recently, a distinction has been drawn between conventional false memories, which misrepresent specific facts, and deep distortions, which misrepresent relations that connect facts. We report the first study of adult developmental trends in deep distortions, using a paradigm in which people make conjoint recognition judgments about incompatible facts (e.g., Was Einstein born in Austria, Germany, or Switzerland?). As conventional false memories increase over the adult lifespan, it is natural to expect that deep distortions will do likewise. Surprisingly, however, the modal explanation of adult increases in false memory predicts that deep distortions will be developmentally invariant. We tested that prediction in two experiments that measured three deep distortions (violations of the logical laws of additivity, countable additivity, and universal event) in memory for real-world incompatibility relations (e.g., size of planets, geographical location of companies, people in historical events). In Experiment 1, robust violations of all three laws were detected in younger adults (N = 105; M_age = 20), and as predicted, those violations did not increase in adults (N = 182; Mage = 33) or older adults (N = 176; M_age = 62). Experiment 2 was designed to test whether deep distortions would increase with age when there was stronger support for retrieving verbatim memories, but once again, deep distortion levels were the same in young adults (N = 81; M_age = 19), adults (N = 167; M_age = 34), and older adults (N = 170; M_age = 62). Conjoint recognition analyses revealed that throughout the adult lifespan, verbatim memory played no role in deep distortions. Other analyses revealed that although incompatible facts are perfectly compensatory in the real world (Einstein could only be born in Germany to the extent that he was not born in Austria or Switzerland), memory for incompatible facts is noncompensatory throughout the adult lifespan.

Human cognitive abilities exhibit positive interrelationships that can be represented by a latent general intelligence factor (g). Differentiation hypotheses propose that there are systematic interindividual differences in the strength of g, specifically along the dimensions of ability level (ability differentiation) and age (age differentiation). Despite the potential implications for cognitive theory and assessment, the available evidence on the matter is inconclusive. We present comprehensive analyses of differentiation effects across the lifespan, drawing on the meta-analytic integration of nonlinear factor analyses with German standardization samples (N = 4,129) of the most widely used intelligence tests worldwide (i.e., the Wechsler tests). Results support ability differentiation at all ages, with particularly large effect sizes in young adults, and suggest a complex pattern of age differentiation and dedifferentiation across the lifespan. These findings challenge the uniformity of g, highlighting the need to account for differentiation effects in cognitive theories and assessment.

Prosociality tends to increase with age, but whether older adults (OA) are more willing than younger adults (YA) to extend their prosocial behaviors beyond close social circles remains a topic of debate. This study aimed to address this controversy and explore the underlying mechanisms of age-related differences in prosociality through the lens of social discounting and gain-and-loss framing. One hundred twenty-three younger adults and 135 older adults participated in a social discounting task (measuring prosocial tendencies toward various social relationships) with various framings (self-oriented framing, other-oriented framing, and control condition). Compared to younger adults, older adults exhibited higher overall prosociality and treated socially close and distant others more evenly, indicating lower levels of selectivity in prosociality. Notably, the interaction effect between age and framing revealed that other-oriented framing amplified the prosocial tendencies of older adults, particularly toward socially distant others but not younger adults. These findings suggest other-oriented framing specifically reduced older adults' selectivity in prosociality, highlighting their prioritization of others' welfare and aversion to others' losses. This supports the notion that older adults' prosociality may be driven by other-oriented motivation rather than self-interest. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

According to the Flynn effect, performance on cognitive ability tests has improved over the past decades. However, we know very little about whether such historical improvements generalize to middle-aged adults (aged 45-65) and differ across nations. We used harmonized data on episodic memory from nationally representative longitudinal panel surveys across a total of 16 countries (United States, Mexico, China, England, and countries in Continental, Mediterranean, and Nordic Europe). We compared historical change in age-related trajectories of episodic memory among middle-aged adults. Our sample included 117,231 participants who provided 330,390 observations. Longitudinal multilevel regression models revealed that today's middle-aged adults in the United States perform worse on episodic memory tests than their peers in the past. By contrast, today's middle-aged adults in most other countries perform better on these tests than their peers in the past. However, later-born cohorts of U.S. and Chinese middle-aged adults experienced less steep within-person decrements-or even increments-in episodic memory than earlier born cohorts. Historical change trends persisted when controlling for sociodemographic factors, as well as for indicators of physical and mental health. Differences in episodic memory by gender and education became smaller over historical time across all nations. Our findings suggest that countries differ considerably in episodic memory performance, by more than half a standard deviation, and in the direction and size of how midlife episodic memory trajectories have changed over historical time. Further factors related to historical changes in midlife episodic memory need to be identified by future research. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
