We often seek information without any explicit incentives or goals (i.e., noninstrumental information seeking, often noted as a manifestation of curiosity). Does noninstrumental information-seeking change with age? We tried to answer the question by making a critical distinction between two information-seeking behaviors: diversive information seeking (i.e., information seeking for topics a person knows little about) and specific information seeking (i.e., information seeking to deepen a person's existing knowledge of a topic). Five hundred participants (age range: 12-79 years old) spontaneously read new facts about different topics. After reading each fact, participants were given the choice to read more facts about the current topic or return to the selection menu to learn about a new topic. We found that with increasing age, participants chose to explore more facts within a topic (i.e., increased specific information seeking) and switched less frequently to new topics (i.e., decreased diversive information seeking). These results indicate that while young people seek out a broader range of information, as people grow older, they develop a preference to deepen their existing knowledge.

This is an introduction to the special issue "Adult Age Differences in Language, Communication, and Learning from Text." These articles illustrate the great variety of language use through the adult lifespan, tell us a little more-and invite further inquiry.

The redundancy hypothesis proposes that older listeners need a larger array of acoustic cues than younger listeners for effective speech perception. This research investigated this hypothesis by examining the aging effects on the use of prosodic cues in speech segmentation in Mandarin Chinese. We examined how younger and older listeners perceived prosodic boundaries using three main prosodic cues (pause, final lengthening, and pitch change) across eight conditions involving different cue combinations. The stimuli consisted of syntactically ambiguous phrase pairs, each containing two or three objects. Participants (22 younger listeners and 22 older listeners) performed a speech recognition task to judge the number of objects they heard. Both groups primarily relied on the pause cue for identifying prosodic boundaries, using final lengthening and pitch change as secondary cues. However, older listeners showed reduced sensitivity to these cues, compensating by integrating the primary cue pause with the secondary cue pitch change for more precise segmentation. The present study reveals older listeners' integration strategy in using prosodic cues for speech segmentation, supporting the redundancy hypothesis.

Emotional content, specifically negative valence, can differentially influence speech production in younger and older adults' autobiographical narratives, which have been interpreted as reflecting age differences in emotion regulation. However, age differences in emotional reactivity are another possible explanation, as younger and older adults frequently differ in their affective responses to negative and positive pictures. The present experiment investigated whether a picture's valence (pleasantness) and arousal (intensity) influenced older adults' production of narratives about those pictures. Thirty younger and 30 older participants produced narratives about pictures that varied in valence (positive, negative, and neutral) and arousal (high, low). Narratives were recorded via Zoom, transcribed, and analyzed with Linguistic Inquiry and Word Count-22 to get measures of emotional word use, disfluencies, and linguistic distance. Results showed that negative valence increased age differences in speech production independent of picture arousal: Relative to younger adults, older adults used more positive words, fewer negative words, and had more silent pauses when telling narratives about negative pictures. In contrast, high arousal decreased age differences such that older adults used fewer positive words in narratives about positive pictures and more linguistically distant words evidenced by fewer present-tense verbs, relative to narratives about low-arousal pictures. Contrary to an explanation of enhanced regulation or control over emotions in older adulthood, these findings support the idea that older adults' speech production is influenced by their reactivity or affective response to emotional stimuli even when the task is not to communicate one's emotions.

Emotional empathy is a congruent emotional response stemming from another's emotional state and has mixed evidence for its association with age. We sought to synthesize existing data to investigate cross-sectional changes in emotional empathy across adulthood using random-effects meta-analyses. Embase, APA PsycInfo, Medline, and Scopus databases were systematically searched until October 2022. Thirty-three studies assessed age categorically by comparing older (M = 68.42, SD = 4.95) with younger (M = 27.55, SD = 6.82) adults and demonstrated higher emotional empathy in older adults (g = 0.10, p = .039). Seven studies examined age continuously (18-100 years), resulting in a positive correlation with age (z_r = .08, p = .033). Subgroup analyses identified age effects differed based on the emotional empathy measure but not on measure type (state vs. trait) or gender ratio (73% women and 27% men). Cross-sectional results indicate emotional empathy may increase across adulthood. These results clarify the previously mixed reports of typical emotional empathy functioning in later life. Age effects varying due to the emotional empathy measure examined indicate that these measures' convergent validity should be reexamined. Further research should employ older, population-based, non-western, educated, industrialized, rich, and democratic samples and longitudinal designs.

Prior research has shown that some personality traits are associated with cognitive outcomes and may confirm risk or protection against cognitive decline. The present study expands on previous work to examine the association between a more comprehensive set of psychological characteristics and cognitive performance in a diverse cohort of older adults. We also examine whether controlling for brain atrophy influences the association between psychological characteristics and cognitive function. A total of 157 older adults completed a battery of psychological questionnaires (Openness to Experience, Conscientiousness, Agreeableness, Neuroticism, Extraversion, positive affect, negative affect-sadness, negative affect-anger, sense of purpose, loneliness, grit, and self-efficacy). Cognitive outcomes were measured across multiple domains: episodic memory, semantic memory, executive function, and spatial ability. Baseline brain (MRI) variables included gray matter, hippocampus, and total white matter hyperintensity volume. Parallel process, multilevel models yielded intercept (individual cognitive domain scores) and linear slope (global cognitive change) random effects for the cognitive outcomes. Positive affect (β = 0.013, SE = 0.005, p = .004) and Openness (β = 0.018, SE = 0.007, p = .009) were associated with less cognitive change, independent of baseline brain variables and covariates. Greater sadness predicted more cognitive decline when controlling for covariates, but not brain atrophy. A variety of psychological characteristics were associated with the cross-sectional measures of cognition. This study highlights the important impact of positive and negative affect on reducing or enhancing the risk of longitudinal cognitive decline. Such findings are especially important, given the available efficacious interventions that can improve affect. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Emotions elicited by personal event memories change over time such that negative affect fades more quickly than positive affect. This asymmetric fade is called the fading affect bias (FAB) and has been posited as a mechanism that helps promote a positive outlook on life. A similar bias toward positive information (i.e., the positivity effect) driven by greater emphasis on emotion regulation has been demonstrated in older adults. The current research uses two age-diverse community samples to examine the relationship between age and the strength of FAB. Participants recalled positive and negative event memories and rated the intensity of affect at the time of the event (i.e., retrospectively) and at the time of recollection. Participants of all ages exhibited a significant FAB, and crucially, the strength of the effect was positively associated with age. Age-based differences in psychological well-being and recalled event intensity had no influence on the relationship between age and FAB. The relationship was, however, related to greater personal importance placed on positive (but not negative) events. The findings are consistent with the socioemotional selectivity theory and suggest another mechanism through which emotion regulation is associated with aging to maintain a positive outlook on life.

The way older adults perceive their own aging processes influences their mental health, but we know little about how this occurs in a dyadic context, where spouses' perceptions and health are often intertwined. The present study sought to identify dyadic profiles of self-perceptions of aging (SPAs) in couples and examine how certain profiles are associated with each partner's mental health over time. A pooled sample of 3,850 heterosexual couples aged 50+ in the Health and Retirement Study (2012/2014) rated positive and negative SPAs and provided data on demographic characteristics, couple relationships, and health. We tracked these couples' depressive symptoms over 2 years (2014/2016). Latent profile analysis revealed five profiles of couples' SPAs: similarly positive (20%), similarly negative (6%), similarly average (38%), husband negative (20%), and wife negative (17%). Physical health and marital quality consistently differentiated couples in profile membership. Couples with similarly positive and similarly average SPAs reported the smallest increases in depressive symptoms over time, and couples with similarly negative SPAs fared worst in mental health. We observed interesting gender differences across profiles; husbands in the husband negative profile reported significantly greater increases in depressive symptoms than those in the wife negative profile. Yet, wives in these two profiles did not differ in their depressive symptoms over time, and they reported worse mental health than wives in the similarly positive and similarly average profiles. This study adds to the emerging literature that advocates for an interpersonal approach to SPAs and reveals risk and resilience in couples as they age together.

We often encounter more information than we can remember, making it critical that we are selective in what we remember. Being selective about which information we consolidate into our long-term memory becomes even more important when there is insufficient time to encode and retrieve information. We investigated whether older and younger adults differ in how time constraints, whether at encoding (Experiment 1) or retrieval (Experiment 2), affect their ability to be selective when remembering important information that they need to recall later. In Experiment 1, we found that younger and older adults exhibited similar selectivity, and the participants remained selective when rushed at encoding. In Experiment 2, older adults maintained their selectivity when given insufficient time at retrieval, but younger adults' selectivity was increased when given limited recall time. Altogether, the present experiments provide new support for negligible, and in some cases, even beneficial, effects of time constraints on older and younger adults' ability to selectively encode and retrieve the most valuable information. These findings may provide insight into a mechanism that allows older adults to use their long-term memory efficiently, despite age-related cognitive declines, even when faced with constraining encoding and retrieval situations.

People spontaneously segment continuous ongoing actions into sequences of events. Prior research found that gaze similarity and pupil dilation increase at event boundaries and that older adults segment more idiosyncratically than do young adults. We used eye tracking to explore age-related differences in gaze similarity (i.e., the extent to which individuals look at the same places at the same time as others) and pupil dilation at event boundaries. Older and young adults watched naturalistic videos of actors performing everyday activities while we tracked their eye movements. Afterward, they segmented the videos into subevents. Replicating prior work, we found that pupil size and gaze similarity increased at event boundaries. Thus, there were fewer individual differences in eye position at boundaries. We also found that young adults had higher gaze similarity than older adults throughout an entire video and at event boundaries. This study is the first to show that age-related differences in how people parse continuous everyday activities into events may be partially explained by individual differences in gaze patterns. Those who segment less normatively may do so because they fixate less normative regions. Results have implications for future interventions designed to improve encoding in older adults.
