Aging alone and financial insecurity predict depression: a path analysis of objective and subjective indices.

OBJECTIVES: This study draws on conservation of resources theory and transactional stress theory to guide our understanding of how social isolation, financial insecurity, and social support serve as a balance of both risk and protection for late-life depression. METHODS: Data were from the Leave-Behind Questionnaire in the 2016 (N = 4293) and 2018 (N = 4714) waves of the Health and Retirement Study. We conducted a cross-sectional path analysis via structural equation modeling, including objective and subjective perspectives. The same model was tested in both samples. RESULTS: Both social isolation and financial insecurity were associated with depression. We found several mediating risks and protective factors of these relationships. Objective financial status affected depression through both perceived financial insecurity and perceived social isolation, whereas objective isolation affected depression through perceived social support. This mediation model was -significant after adjusting for confounders. CONCLUSION: This study underscores the importance of investigating the balance between risk and protection for depression, in the rising number of older adults aging alone in society. Findings suggest that objective and perceived measures offer unique windows into psychological constructs. Considering both objective and subjective perspectives may provide alternative targets for subsequent interventions to improve mental health in later life.

Adult Age Differences in Sensitivity to Semantic Satiation.

OBJECTIVE: In this study, we investigated age differences in sensitivity to semantic satiation.Semantic satiation was conceptualized as occurring within a semantic activation framework. METHOD: A prime or to-be-satiated word (e.g., ANIMAL) was presented repeatedly for an average of 2.5, 12.5, or 22.5 times. Afterward, a word triad comprised of two related words (e.g., PURPLE, YELLOW) and one unrelated word (e.g., DOG) was presented. The two related words were designated as nontargets or context words in the display and the unrelated word was the target. Participants were instructed to indicate as quickly and as accurately as possible which of the words in the triad was the unrelated word by pressing a key which was spatially compatible to the position of the stimulus on the CRt. RESULTS: For young but not older adults, there was an attenuation of priming effects in the response latency data as repetition of the prime increased. CONCLUSION: These results were interpreted as evidence that older adults are less sensitive to the semantic satiation phenomenon than young adults.

Sources of nonreplicability in aging ethnoracial health disparities research.

The older adult population in the U.S. is becoming increasingly diverse across a constellation of factors including ethnoracial group, socioeconomic status, and immigration status. However, our understanding of the consequences of this diversity for cognitive and mental health is masked by the lack of inclusion of diverse sample characteristics, the use of assessments that might hold a different meaning for different groups of people, and analytical choices that do not probe the impact of diverse characteristics or assume an unwarranted degree of homogeneity within groups. Each of these factors not only hinders our ability to understand various psychological mechanisms that differ as a function of age but also threatens the likelihood of replicability across aging research studies. This article provides our perspective on three key sources of nonreplicability in ethnoracial health disparities research among older adults: (a) what is lost in creating monolithic groups rather than identifying subgroups of minorities, (b) understanding aging from the perspective of intersecting identities, and (c) biases of research materials. We also provide recommendations to increase replicability in aging research with respect to the challenges outlined. Approaching questions on aging from a health disparities lens can both increase the generalizability of research outcomes and improve initiatives of social justice that are long overdue.

Decision-making quality of younger and older adults in familiar and unfamiliar domains.

Age-related differences in purchasing decisions were examined as a function of age and familiarity. On each trial, participants received purchasing options which varied in quality but ultimately cost the same amount of money. On half the trials, participants made decisions about items familiar to younger adults and on the other half of the trials, participants made decisions about products familiar to older adults. The participants' task was to choose the option that provided the best value for the money. We were particularly interested in participants' performance when inferencing was required to select the optimal option from the two choices. Younger adults outperformed older adults in unfamiliar but not familiar domains. It appeared that both younger and older adults used inferencing and elaborative processing to make the best decision in familiar domains but that only younger adults used inferencing and elaborative processing in unfamiliar domains.

Effects of homograph meaning frequency on semantic satiation.

This study examined the effects of homograph meaning frequency on semantic satiation within an ambiguity resolution paradigm. Participants received 3 homograph conditions: the concordant (QUICK-FAST-SPEEDY), discordant (HUNGER-FAST-SPEEDY) and neutral (CEILING-FAST-SPEEDY). On each trial, a prime (e.g., QUICK) was presented for various numbers of repetitions. Afterward, the prime was removed and participants made relatedness judgments about a homograph and target. On half of the trials, the prime was related to a high-frequency meaning of the homograph, and on the other half of the trials, the prime was related to a low-frequency meaning. The concordant condition yielded evidence of semantic satiation across meaning frequency conditions (QUICK-FAST-SPEEDY), but the discordant condition only yielded evidence of semantic satiation when the prime activated a subordinate meaning of the homograph (HUNGER-FAST-SPEEDY).

Aging, imagery, and the bizarreness effect.

This study examined the bizarre imagery effect in young and older adults, under incidental and intentional conditions. Intentionality was manipulated across experiments, with participants receiving an incidental free recall test in Experiment 1 and an intentional test in Experiment 2. This study also examined the relation between working memory resources and the bizarreness effect. In Experiment 1 young and older adults were presented with common and bizarre sentences; they later received an incidental recall test. There were no age differences in sensitivity to the bizarreness effect in Experiment 1 when ANOVAs were used to analyze the data. However, when the bizarreness effect was examined in terms of effect size, there was evidence that younger adults produced larger bizarreness effect sizes than younger adults. Experiment 2 further explored age differences in sensitivity to the bizarreness effect by presenting young and older adults with bizarre and common sentences under intentional learning conditions. Experiment 2 failed to yield age differences as a function of item type (bizarre vs. common). In addition, Experiment 2 failed to yield significant evidence that the bizarreness effect is modulated by working memory resources. The results of this study are most consistent with the distinctiveness account of the bizarreness effect.
