Reducing discrepancies between actual and ideal affect across adulthood: the roles of activity flow conduciveness, pleasantness, and familiarity.

Previous findings demonstrate that people often do not feel how they want to feel, supporting the distinction between "actual affect" and "ideal affect." But are there certain activities that reduce the discrepancy between actual and ideal affect? Based on flow theory and socioemotional selectivity theory, we examined whether the discrepancy between people's actual and ideal positive affect would be smaller during activities that were more conducive to flow (a state of intense absorption and concentration), pleasant, and familiar. In Study 1, U.S. participants aged 17-79 (N = 393) reported their ideal affect and how they felt during activities with varying degrees of challenges and skills. For both low-arousal positive affect (LAP) and high-arousal positive affect (HAP), participants reported smaller actual-ideal affect discrepancies during flow-conducive activities (when skills matched challenges). Study 2 was a 14-day experience sampling study, in which Hong Kong participants aged 18-83 (Nindividual = 109) reported their momentary actual and ideal affect, and how pleasant and familiar their activities were (Nexperience = 3,815). Greater activity familiarity was associated with smaller discrepancies in actual-ideal LAP, while greater activity pleasantness was associated with smaller discrepancies in actual-ideal HAP. These findings provide insights on the activities that help people achieve their ideal affect more easily.

Enhancement of the Wear Resistance and Corrosion Resistance of Electroplated Ni-W-B Coatings Using PDA-Functionalized VC.

In this study, vanadium carbide (VC) was used as the raw material to synthesize PDA-functionalized VC (P-VC). VC and P-VC were added as nanoreinforced materials to the Ni-W-B coating. The effects of the two nanomaterials on the morphology, wear resistance, and corrosion resistance of the Ni-W-B coatings were investigated and compared. The experimental results show that the surface of the Ni-W-B/P-VC coating is denser and more uniform than that of the Ni-W-B and Ni-W-B/VC coatings, and there are no obvious defects on the surface. According to the hardness test, the Ni-W-B/P-VC coating reaches the highest microhardness of 887.1 HV. According to the friction and wear tests, the Ni-W-B/P-VC coating has the shallowest scratches, the lowest average friction coefficient (COF = 0.274), and the lowest wear rate (9.578 × 10-8 mm2/N). The corrosion resistance is the best, the corrosion rate is 0.0456 mm/y, and the impedance value Rt reaches 14,501 Ω·cm2.

Age-Differential Role of Gaze Reinstatement in Recognition Memory for Negative Visual Stimuli.

OBJECTIVES: Although research has shown that the replay of encoding-specific gaze patterns during retrieval, known as gaze reinstatement, facilitates memory retrieval, little is known about whether it differentially associates with the negativity preference in memory (defined as enhanced memory for negative stimuli relative to neutral stimuli in this study) among younger and older adults. The present study aims to address this research gap. METHODS: A total of 33 older adults (16 women; aged 58-69 years, M = 63.48, SD = 2.98) and 36 younger adults (10 women; aged 18-26 years, M = 20.39, SD = 1.57) completed a remember/know recognition memory task involving negative and neutral pictures. Their eye movements were tracked during both the memory encoding and retrieval phases. RESULTS: Younger and older adults had better memory for negative than neutral pictures. Older adults exhibited significantly stronger gaze reinstatement for negative than neutral stimuli, while this difference was nonsignificant in younger adults. Moreover, gaze reinstatement is positively linked to memory performance in both age groups. DISCUSSION: The results suggest that gaze reinstatement may play age-differential roles in the negativity preference of memory. Negative valence may enhance gaze reinstatement, which improves subsequent recognition memory, particularly among older adults. The finding contributes to a better understanding of the mechanisms underlying the negative preference for memory in different age groups.

Facial Trustworthiness Influences Age Differences in Visual Attention Toward Credible Versus Non-credible Messages.

Background and Objectives: The literature on consumer decision-making and aging suggests that older adults make less optimal buying decisions than younger adults do, partly because older adults tend to perceive salespersons' faces as more trustworthy. This study aims to directly test the difference in the effect of perceived facial trustworthiness on buying intention between younger and older adults. It also aims to reveal the underlying mechanisms of this age-related difference by testing whether a more trustworthy face disrupts older adults' attention toward credible (vs. non-credible) information to a higher degree compared with younger adults. Research Design and Methods: A sample of 92 younger (aged 18-37 years) and 83 older (aged 60-82 years) adults viewed advertisements for 32 products while their eye movements were captured by an eye tracker to measure their fixation duration (as an indicator of attention). The advertisements varied in terms of the credibility of the content and the trustworthiness of the salesperson's face. Results: Both age groups showed higher buying intentions for products featured in advertisements with higher credibility and facial trustworthiness. When facial trustworthiness was lower, both age groups showed greater attentional preferences for credible over non-credible content. However, this distinction in attention disappeared in older but not younger adults with an increase in facial trustworthiness. Discussion and Implications: Our findings suggest that although facial trustworthiness generally increases buying intention of both younger and older adults, it only reduces older (but not younger) adults' attentional discrimination between credible and non-credible content. This paper offers a novel and promising mechanism for the increase in fraud vulnerability in late adulthood.

The perks of doing housework: Longitudinal associations with survival and underlying mechanisms.

BACKGROUND: Although the majority of existing literature has suggested positive effects of housework on older adults' health and survival rate, the underlying mechanisms of such effects remain unclear. To address potential mechanisms, the present study examined the association between older adults' housework engagement and days of survival across 14 years and tested three potential mediation pathways in this association. METHODS: Four thousand Hong Kong older adults (50% female; aged between 65 and 98 years) participated in a longitudinal study in which they reported initial housework engagement and health status across three domains (cognitive functioning, physical health, and mental health) at the baseline, and the numbers of days they survived over the subsequent 14-year period were recorded. Linear regression, Cox proportional hazard, and parallel mediation analyses were performed to examine the relationship between housework engagement and days survived, and the mediating effects of these three health factors. RESULTS: The results showed a positive association between housework engagement and days survived after controlling for demographic variables (age, sex, education, marital status, subjective social status, and living alone). Physical health and mental health, but not cognitive functioning, partially mediated the relationship between housework engagement and days survived. The findings suggest that doing housework may contribute to longer survival by improving older adults' physical and mental health. CONCLUSION: The current study confirms positive relations of housework with health and mortality among Hong Kong older adults. As the first study examining the relationships and mediation pathways between doing housework and survival in later life, the findings advance our understanding of the mechanisms underlying the positive association between housework and mortality and provide insights for future daily-life health-promotion interventions for older adults.

Subjective Health and Physical-Activity Engagement across Adulthood: Distinguishing between Within-Person and Between-Person Associations.

INTRODUCTION: It is assumed that age-related increases in loss (e.g., health decline) motivate behavioral changes (e.g., prevention of health decline) across adulthood. This assumption has rarely been directly tested in empirical research, and the current study seeks to fill this gap. METHODS: By performing random intercept cross-lagged panel model and multilevel modeling analyses on a three-wave longitudinal dataset from the Midlife in the United States survey (N = 7,108; 51.6% female; between 20 and 75 years at T1), we examined the between-person and the within-person associations between subjective health and engagement in physical activity. Chronic conditions, difficulty in performing daily activities, and demographic variables were controlled for. RESULTS: At the between-person level, subjective (i.e., self-rated) health was positively associated with physical activity in the whole sample and the older subgroup (T1 age >55 years), but not in the younger subgroup (T1 age <35 years). At the within-person level, the association between subjective health and subsequent physical activity was negative in the whole sample and the older subgroup, but nonsignificant (between T1 and T2) or positive (between T2 and T3) in the younger subgroup. DISCUSSION: This study revealed various associations between subjective health and engagement in physical activity across levels (the within- vs. between-person level) and across age groups (younger vs. older group). The finding contributes to a better understanding of people's health behavior in reaction to health decline at different ages. It also supports the proposition that age-related intraindividual increases in losses (e.g., health decline) motivate behaviors that counteract such losses (e.g., physical activity that protects health).

The Hong Kong Grocery Shopping Dialog Task (HK-GSDT): A Quick Screening Test for Neurocognitive Disorders.

The Hong Kong Grocery Shopping Dialog Task (HK-GSDT) is a short and easy-to-administer cognitive test developed for quickly screening neurocognitive disorders (NCDs). In the test, participants are instructed to do a hypothetical instrumental activity of daily living task of purchasing ingredients for a dish from a grocery store and verbally describe the specific shopping procedures. The current study aimed to validate the test with a sample of 545 Hong Kong older adults (58.8% female; aged 73.4 ± 8.37 years), including 464 adults with normal cognitive function, 39 with mild NCD, and 42 with major NCD. Demographic characteristics (i.e., sex, age, education) and clinical diagnosis of cognitive states (i.e., major NCD, mild NCD, and normal aging) were collected. Cognitive functioning was measured using the HK-GSDT and several standardized NCD-screening tests. The results showed good reliability (i.e., internal consistency) and structural validity in the HK-GSDT. It discriminated among different cognitive conditions, particularly between major NCDs and the other conditions, as effectively as did the existing standardized neurocognitive tests (e.g., Montreal Cognitive Assessment, Hong Kong List Learning Test). Moreover, the HK-GSDT explained additional variance of cognitive condition on top of those standardized neurocognitive tests. These results indicate that the HK-GSDT can be used alone, or in combination with other tests, to screen for NCDs.

B Vitamin Supplementation Slows Cognitive Decline in Mild Cognitive Impairment Patients with Frontal Lobe Atrophy.

BACKGROUND: The effects of B vitamins on mild cognitive impairment (MCI) patients' cognition have been mixed, suggesting the existence of moderating factors. OBJECTIVE: A post hoc analysis of a negative B vitamin trial was performed to examine the potential modulating effect of regional brain atrophy on the cognitive response to B vitamins in MCI patients. METHODS: In the 24-month randomized trial, 279 MCI outpatients took 500µ#x03BC;g methylcobalamin and 400µ#x03BC;g folic acid once per day or placebo tablets once per day. Sixty-four aspirin users were excluded from analysis as aspirin use has been found to have significant negative interaction effects. Subjects were followed up at months 12 and 24. The primary cognitive outcome was clinical dementia rating scale sum of boxes (CDR_SOB). In a subgroup of 83 subjects, MRI brain scans were performed at baseline to estimate regional brain atrophy ratios. RESULTS: Among the trial subjects who had MRI data, B vitamin supplementation had no significant effect on CDR_SOB, despite having significant homocysteine lowering effects. The atrophy ratio of the left frontal lobe significantly moderated the effect of B vitamin supplementation on CDR_SOB, after adjusting for confounders, in that B vitamin supplementation was associated with lower CDR_SOB scores (i.e., better cognitive function) at the 24th month among those patients with above median atrophy ratios, but not among those with lower atrophy ratios, in the left frontal lobe. CONCLUSION: B vitamins may be more effective in slowing down cognitive decline in MCI patients with atrophy in the left frontal lobe.

Does Goal Orientation Modulate Satisfaction With Cognitive Performance in Different Age Groups?

OBJECTIVES: The current experiment tested the causal effect of goal orientation on subjective satisfaction with performance on a cognitive task. METHOD: A sample of N = 231 young, middle-aged, and older adults (21-79 years) completed a dot-memory task in one of 3 goal orientation conditions aiming for improvement, maintenance, or avoidance of decline in performance. RESULTS: Bayesian analyses showed that in all age groups, goal orientation influenced actual performance, but did not affect perceived performance or performance satisfaction. Performance satisfaction was positively correlated with perceived performance, but not with actual performance. DISCUSSION: The findings suggest that whether goal orientation benefits older adults' subjective well-being might depend on (a) the goal content (previous research targeted personal goals) or (b) whether it enhances their perception of the status quo (and thus reduces the discrepancy between actual and desired states). This study contributes to a better understanding of the role of goal orientation in subjective well-being across adulthood.

Time Unpacking Effect on Intertemporal Decision-Making: Does the Effect Change With Choice Valence?

People often feel that a period of time becomes longer when it is described in more detail or cut into more segments, which is known as the time unpacking effect. The current study aims to unveil how time unpacking manipulation impacts intertemporal decision making and whether the gain-loss valence of choices moderates such impacts. We recruited 87 college students (54 female) and randomly assigned them to the experimental conditions to complete a series of intertemporal choice tasks. The subjective values of the delayed choices were calculated for each participant and then analyzed. The results showed that participants perceived longer time delays and higher subjective values on the delayed gains (but not losses) in the time unpacking conditions than in the time packing conditions. These results suggest that time unpacking manipulation not only impacts time perception but also other factors, which in turn, influence the valuation of delayed outcomes and thereby intertemporal choices. The results are discussed in comparison to previous studies to highlight the complexity of the mechanism underlying the effect of time unpacking on intertemporal decision making.

"When i feel lonely, i'm not nice (and neither are you)": the short- and long-term relation between loneliness and reports of social behaviour.

Loneliness can negatively impact peoples' lives. However, it is unclear whether loneliness influences, and is influenced by, people's social experience. Consistent with socio-cognitive models of loneliness, we hypothesised that loneliness predicts experienced social behaviour and vice versa. We tested these hypotheses in a sample of N = 245 college students (31.4% male) who participated in a two-year longitudinal survey. A subsample (n = 87, 24.1% male) also participated in a 14-day diary survey. This enabled us to test both long- and short-term associations between loneliness and social behaviour. Moreover, we investigated between-person (i.e. prolonged) and within-person (i.e. temporary) effects between loneliness and reports of social behaviour. Multilevel modelling showed that loneliness predicted individuals' reports of own and others' positive social behaviour, and reports of others' positive social behaviour predicted loneliness at the between-person level (while most of the effects at the within-person level were nonsignificant) in both the short and long term. The results suggest that people with higher levels of prolonged (but not temporary) loneliness tend to report less positive social behaviour, and people who experience others' behaviour less positively are more likely lonely. This study highlights the relation between prolonged loneliness and social behaviour.

It Is What You Have, Not What You Lose: Effects of Perceived Gains and Losses on Goal Orientation Across Adulthood.

OBJECTIVES: Goal orientation tends to shift from predominantly striving for gains to maintenance and loss avoidance across adulthood. A dominant hypothesis states that age-related increases in losses drive the motivational shift. The present study tests this hypothesis and an alternative, namely that perceived accumulation of resources/assets and discrepancy between the actual and desired state underlie the stronger maintenance and loss-avoidance orientation in older than younger adults. METHODS: Data from N = 182 U.S. adult participants on Amazon Mechanical Turk (preregistered; 50.0% female; 19-77 years, M = 45.1, SD = 15.86) comprise measures of demographics, goal orientation in 16 selected life domains as well as perceived accumulation, losses, actual-desired discrepancy in the same domains. RESULTS: Multilevel modeling analyses showed that, as expected and confirming prior research, gain orientation decreased and maintenance orientation increased with age. Moreover, both perceived losses and accumulation of resources/assets increased with age, while the actual-desired discrepancy decreased. Larger perceived accumulation and smaller actual-desired discrepancies were associated with stronger maintenance orientation. Regardless of age, a smaller actual-desired discrepancy was also associated with stronger loss-avoidance orientation. Contrary to predictions, perceived losses were negatively associated with gain orientation, but not significantly associated with maintenance or loss-avoidance orientation. DISCUSSION: Results replicate the shift in goal orientation across adulthood. Speaking against the loss hypothesis, perceived accumulation of resources/assets and actual-desired discrepancy seem to play an important role in determining goal orientation over adulthood, while the role of perceived losses may be less significant than commonly assumed.

Remembering positive or relevant information? Cultural relevance may moderate the age-related positivity effect in memory.

The age-related positivity effect might be driven by age differences in seeking emotional positivity or the meaning attached to positive information. To examine these 2 hypotheses, we recruited young and older Mainland Chinese adults to complete a recognition memory task, in which they viewed and recognized a series of pictures varying in emotional valence (neutral, positive, or negative) and cultural relevance (relevant to Chinese or Western culture). Participants were instructed to just view the pictures (Experiment 1), to focus on the emotional valence of the pictures (Experiment 2a), to focus on the cultural relevance of the pictures (Experiment 2b), or to focus on both (Experiment 2c). Because cultural relevance could alter the meaning of a picture without changing its emotional valence, the age-related positivity effect should not be moderated by cultural relevance if the effect is driven by age differences in seeking emotional positivity. In contrast, such a moderation effect should be detected if the age-related positivity effect is driven by age differences in seeking meaning. The results of Experiment 2b supported the latter speculation by finding an age-related positivity effect for Chinese pictures but not for Western pictures, although the other 3 experiments found an age-related positivity effect that was not moderated by cultural relevance. These results show that the motivation to seek meaning plays a role in the age-related positivity effect at least in certain situations. The cross-experiment divergencies of the results are discussed. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Cultural Relevance Reduces the Enhanced Neural Processing of Positively Valenced Information in Older Adults.

OBJECTIVES: This study investigated (a) whether the age-related enhancement in processing positive relative to negative emotional information happened at the early and/or late processing stages and (b) if the age-related positivity effect was modulated by cultural relevance using event-related brain potential (ERP). METHODS: Seventeen younger and 19 older Chinese adults judged the emotional valence of Chinese and Western pictures while electroencephalogram (EEG) was recorded and analyzed by temporospatial principal component analysis to dissociate the processing stages. RESULTS: (a) Larger N100 for negative than positive pictures was observed in younger, but not older adults, while older but not younger adults showed larger late anterior P300 for positive than negative pictures. (b) Older adults showed larger early posterior P300 for positive than negative Western pictures, but not culturally relevant Chinese pictures; such modulation effect by cultural relevance was absent in younger adults. DISCUSSION: These findings suggest an age-related decrease in sensitivity to negative information in the earlier stage and an age-related increase in sensitivity to positive information in the later stage of cognitive processing. This supports a dual-route model of the age-related positivity effect. Moreover, the age-related positivity effect is more evident for stimuli with less cultural relevance.

Are Older Adults More Willing to Donate? The Roles of Donation Form and Social Relationship.

OBJECTIVES: Whether older adults are more prosocial than younger adults has been under debate. In the current study, we investigated how age differences in prosocial behaviors varied across different contextual factors, that is, donation form, kinship, and social distance. METHODS: To achieve this purpose, 89 younger and 66 older adults took part in a hypothetical donation task in which they were asked to donate money and time to relatives and nonrelatives at various social distances. RESULTS: The results showed that, compared to younger adults, (a) older adults donated less to nonrelatives (regardless of the donation form), but donated a similar amount (in money) or even donated more (in time) to relatives; (b) older adults displayed higher levels of kin selection (favoring relatives over nonrelatives) in both monetary and time donations; and (c) older adults showed higher levels of social discounting (favoring socially close over distant others) in monetary but not time donation. DISCUSSION: The study underscored the importance of contextual factors in understanding age differences in prosocial behaviors such as donation.

Cultural differences in the age-related positivity effect: Distinguishing between preference and effectiveness.

Prior studies have found mixed results regarding whether there are cultural differences in the age-related positivity effect, defined as older adults' showing a greater bias in cognitive processing for positively over negatively and neutrally valenced information relative to younger adults. This study attempted to address this controversy by examining visual attention toward culturally relevant versus irrelevant pictures that differed in valence among younger and older U.S. Americans and Hong Kong Chinese. Preferences (attentional biases toward particular valence) and effectiveness (whether the attentional biases are associated with better mood) were also distinguished. Findings revealed that regardless of cultural relevance of the pictures, older U.S. Americans showed more gaze preference for positive over negative pictures compared to their younger counterparts; this age difference was not found among Hong Kong Chinese. In contrast, older Hong Kong Chinese showed better mood as a function of more gaze preference for positive over negative pictures. Younger Hong Kong Chinese and younger and older U.S. Americans did not show this association. The results suggest that an age-related positivity effect exists at the preference level for U.S. Americans but at the effectiveness level for Chinese.

Development and Validation of Social Motivation Questionnaire.

BACKGROUND AND OBJECTIVES: Information-seeking (IS) and emotion-regulatory (ER) motivation play meaningful roles in age-related changes in social interaction across adulthood. This study aimed to develop and validate the Social Motivation Questionnaire (SMQ) to assess these two types of motivation. RESEARCH DESIGN AND METHODS: Ten items were selected from a pool as the candidate items of SMQ and were administered to 480 German adults (20-91 years old) for validation. These items were also administered to 150 U.S. (18-40 years old) and 131 Hong Kong younger adults (18 to 26 years old) for cultural-invariance examination. RESULTS: Exploratory and confirmatory factor analyses showed that a two-factor, eight-item structure fits the German adults' data well with satisfactory reliability. Multigroup comparisons showed cross-age invariance among younger, middle-aged, and older German adults, as well as cross-cultural invariance among German, U.S., and Hong Kong younger adults. DISCUSSION AND IMPLICATIONS: A new questionnaire, SMQ, was developed and validated to measure IS and ER social motivation across adulthood and across cultures.

Future Time Perspective Impacts Gain-Related but Not Loss-Related Intertemporal Choice.

Future time perspective (FTP) modulates individuals' temporal orientation in selecting their motivations and goals, which widely influences their cognitions and behaviors. However, it remains unclear how FTP exactly affects intertemporal choice. To clarify the effect of FTP on intertemporal choice, 90 college students (Mage = 21.70, SD = 1.23) were randomly assigned to the limited FTP condition (16 males, 29 females) and the open-ended FTP condition (17 males, 28 females). In the limited FTP condition, participants were instructed to imagine their states of being 70 years old, whereas in the open-ended FTP condition, they were instructed to describe their current states. All participants then completed a series of intertemporal choice tasks, in which they chose from gain- and loss-related choices occurring at various time points. Results showed that the participants who received the future-imagining manipulation had more limited FTP compared with those who did not receive the manipulation, which confirmed the validity of the FTP manipulation. A 2 (FTP: limited vs. open-ended) × 2 (type of choice: gain vs. loss) repeated measures ANOVA on discount rate revealed a significant interaction between these two factors. The participants in the limited FTP condition had higher discount rates on gain-related choices but showed no difference on loss-related choices compared with the participants under the open-ended FTP condition. The results suggest that limited FTP could lower individuals' future orientation (i.e., willingness to delay an outcome) on gain-related, but not on loss-related, intertemporal decision-making.

Relationship between neuroticism, childhood trauma and cognitive-affective responses to auditory verbal hallucinations.

Neuroticism has been shown to adversely influence the development and outcome of psychosis. However, how this personality trait associates with the individual's responses to psychotic symptoms is less well known. Auditory verbal hallucinations (AVHs) have been reported by patients with psychosis and non-clinical individuals. There is evidence that voice-hearers who are more distressed by and resistant against the voices, as well as those who appraise the voices as malevolent and powerful, have poorer outcome. This study aimed to examine the mechanistic association of neuroticism with the cognitive-affective reactions to AVH. We assessed 40 psychotic patients experiencing frequent AVHs, 135 non-clinical participants experiencing frequent AVHs, and 126 healthy individuals. In both clinical and non-clinical voice-hearers alike, a higher level of neuroticism was associated with more distress and behavioral resistance in response to AVHs, as well as a stronger tendency to perceive voices as malevolent and powerful. Neuroticism fully mediated the found associations between childhood trauma and the individuals' cognitive-affective reactions to voices. Our results supported the role of neurotic personality in shaping maladaptive reactions to voices. Neuroticism may also serve as a putative mechanism linking childhood trauma and psychological reactions to voices. Implications for psychological models of hallucinations are discussed.

Emotional valence of stimuli modulates false recognition: Using a modified version of the simplified conjoint recognition paradigm.

False recognition results from the interplay of multiple cognitive processes, including verbatim memory, gist memory, phantom recollection, and response bias. In the current study, we modified the simplified Conjoint Recognition (CR) paradigm to investigate the way in which the valence of emotional stimuli affects the cognitive process and behavioral outcome of false recognition. In Study 1, we examined the applicability of the modification to the simplified CR paradigm and model. Twenty-six undergraduate students (13 females, aged 21.00±2.30years) learned and recognized both the large and small categories of photo objects. The applicability of the paradigm and model was confirmed by a fair goodness-of-fit of the model to the observational data and by their competence in detecting the memory differences between the large- and small-category conditions. In Study 2, we recruited another sample of 29 undergraduate students (14 females, aged 22.60±2.74years) to learn and recognize the categories of photo objects that were emotionally provocative. The results showed that negative valence increased false recognition, particularly the rate of false "remember" responses, by facilitating phantom recollection; positive valence did not influence false recognition significantly though enhanced gist processing.
