Nonhuman treatment reduces helping others: self-dehumanization as a mechanism.

Objectification is a daily experience with various negative consequences. In four studies (N = 877), we tested whether and how objectification experience contributes to decreased prosociality. Using correlational designs (Studies 1 and 2), we found that participants' objectification experience negatively predicted their prosocial intention and that self-dehumanization could account for the negative association between objectification and prosocial intention. Next, by manipulating participants' objectification experience, we found the negative effect of objectification on prosocial intention, as well as the mediating role of self-dehumanization (Studies 3 and 4). Additionally, we tested the mediating role of self-dehumanization in comparison with relative deprivation (another potential mediator), and consistently found that self-dehumanization was a stronger mediator in accounting for the effect of objectification on prosocial intention (Studies 1, 2, and 4). Together, our findings support the process of self-dehumanization following objectification and offer new insights into the relationship between objectification and prosociality. The implications and limitations of the research were discussed.

Objectification decreases prosociality: the mediating role of relative deprivation.

Objectification denies individuals' personhood and renders them as tools for facilitating others' goal achievement. With two studies (N = 446), the present investigation aimed to contribute to the literature by testing whether and how objectification impacts prosociality, including prosocial intention and prosocial behavior. Study 1, with a correlational design, aimed to test whether participants with greater experience of objectification would report lower levels of prosociality, and to test whether participants' relative deprivation could account for the proposed association between objectification and prosociality. To further test these associations and provide causal evidence, in Study 2, we manipulated objectification by asking participants to imagine future objectification experiences. These studies converged in support of the negative relationship between objectification and prosocial intention, as well as the mediating role of relative deprivation. Regarding prosocial behavior, our findings support a mediating mechanism between objectification and prosocial behavior, although the evidence for the effect of objectification on prosocial behavior is not sufficient. These findings enrich our understanding of the consequences of objectification, while highlighting interpersonal processes' contribution to prosocial intention and behavior. The limitations and potential future directions were discussed.

High Social Mobility Leads to Delayed Reproduction.

Many important family decisions, such as when to have offspring, essentially manifest different life history strategies, ranging from slow to fast ones. The current research examined how one critical societal factor, social mobility (i.e., the shift of socioeconomic status in a society), may contribute to such slow (vs. fast) life history strategies. With four multi-method studies, including archival data at the national level, a large-sample survey (N = 6787), and experimental studies (N = 497), we found that a high level of social mobility predicted and resulted in delayed reproduction. Specifically, a high level of social mobility, indexed by both objective reality and subjective perception, predicted individuals' positive future expectations. This further leads them to focus on long-term goals and foster a slow life history strategy, i.e., preferring delayed reproduction. Theoretical implications are discussed.

Shifts in patterns of help-seeking during the COVID-19 pandemic: The case of Hong Kong's younger generation.

RATIONALE: Help-seeking can convert an individual's bonding social capital into social support, which has been shown to buffer the impact of psychological distress. The younger generation (individuals aged 15-35 years) have been the least likely to actively seek help despite facing a rising burden of mental health problems. COVID-19 pandemic restrictions may have altered their help-seeking behaviors, but the extent of such shift remains little understood, particularly in Asian contexts. OBJECTIVE: To understand how the younger generation's patterns of help-seeking (activation of different combinations of support sources) have shifted in pandemic times, who have experienced the shift, and what explanatory factors are involved. METHODS: Data were obtained from two waves (2019, 2020) of online survey responses by 438 community-dwelling younger generation people in Hong Kong, recruited through the authors' affiliated institutions and territory-wide community outreach organizations. Latent class analysis was conducted on participants' self-reported help-seeking behaviors in each survey wave. Constituents' characteristics in each latent class were examined, and between-wave changes in individuals' class membership were identified. Logistic regressions identified explanatory factors that significantly explained the changes. RESULTS: Three consistent patterns of help-seeking were identified in both survey waves. A major shift was observed for individuals with poorer mental health histories who faced moderate distress. They relied on their family, friends, and partner pre-pandemic, but no longer activated these supports during the pandemic. Posting status updates on social media, along with various communication habits and sociodemographic factors that differed by age group, were associated with this shift. CONCLUSIONS: Shifts in the younger generation's patterns of help-seeking may be an early warning signal to invest additional resources in facilitating help-seeking among the younger generation. Findings also serve as a reminder that public health restrictions may have inadvertent mental health implications that should be considered in future scenarios.

Permitting immoral behaviour: A generalized compensation belief hypothesis.

When are we more likely to permit immoral behaviours? The current research examined a generalized compensation belief hypothesis that individuals, as observers, would morally tolerate and accept someone paying forward unfair treatment to an innocent person as a means to compensate for the perpetrator's previously experienced mistreatment. Across five experiments (N = 1107) based on economic games (Studies 1-4) and diverse real-life scenarios (Study 5), we showed that participants, as observing third parties, were more likely to morally permit and engage in the same negative act once they knew about previous maltreatment of the perpetrator. This belief occurred even when the content of received and paid-forward maltreatment was non-identical (Study 2), when the negative treatment was received from a non-human target (Study 3) and when the maltreatment was intangible (e.g. material loss) or relational (e.g. social exclusion; Study 5). Perceived required compensation mediated the effect of previous maltreatment on moral permission (Studies 4 and 5). The results consistently suggest that people's moral permission of immoral behaviours is influenced by perpetrator's previous mistreatment, contributing to a better understanding of the nature and nuances of our sense of fairness and contextualized moral judgement.

Women's Self-Objectification Under Competition When They Believe Sex Is Power.

Competitions are ubiquitous and their psychological consequences for women have not received sufficient attention. For this research, we tested whether competition, in either work settings or a broader form of competition for resources, would interact with the sex is power belief to result in self-objectification among women. This prediction was confirmed by a series of studies (N = 1416), including correlational studies, a quasi-experiment, and fully controlled experiments, with samples including company employees, MBA students with work experience, college students currently competing in a job market, and Mechanical Turkers. Competition (or a sense of competition) as a feature of the working environment (Study 1), a real state in life (Study 2), or a temporarily activated state (Studies 3-5) resulted in self-objectification among women who believe sex is power (Study 1) or who enter such a mindset (Studies 2-5). This effect further impaired the pursuit of personal growth (Studies 4 and 5).

Double standards in the COVID-19 pandemic: The moderation of perceived threat.

This research explored whether people hold double standards in a public crisis. We proposed that during the COVID-19 pandemic, people required others to strictly follow self-quarantine rules and other preventive behaviours, whereas they themselves would not, demonstrating double standards. Moreover, this effect would be moderated by the perceived threat from the pandemic. Using data collected in the United States and China, three studies (N = 2180) tested the hypotheses by measuring (Study 1) and manipulating the perceived threat (Studies 2 and 3). We found that people generally applied higher standards to others than to themselves when it came to following the self-quarantine rules. This effect was strong when a relatively low threat was perceived, but the self-other difference disappeared when the perceived threat was relatively high, as the demands they placed on themselves would increase as the perceived threat intensified, but their requirements of others would be constantly strict.

An exchange orientation results in an instrumental approach in intimate relationships.

Although the possession of instrumentality (i.e., partner B being useful to partner A's goal pursuit) can facilitate relationship satisfaction, taking an instrumental approach (i.e., A focusing on B's usefulness and seeing B as a tool to facilitate personal goal attainment) is (often) considered as a callous and depersonalized approach to forming relationships. The current research examined whether adopting an exchange orientation amplifies the tendency for people to take an instrumental approach via the motive to maximize self-gain. Four studies (N = 1446) utilizing samples across different countries, including the United Kingdom, the United States and China, supported this hypothesis. Specifically, during relationship initiation, an exchange (vs. non-exchange) orientation made participants place higher importance on instrumentality rather than traits facilitating intimacy and bonding (Study 1). For established relationships, participants who chronically adopted an exchange orientation (Study 2) and who were temporarily induced to do so (vs. control; Study 3) were more likely to view their significant other as a tool. The final quasi-experiment (Study 4) showed that requiring or being required to offer a bride price - an embodiment of exchange orientation - predicted instrumentality in marriage and subsequently impaired relationship satisfaction. Implications are discussed.

Youth Bullying and Suicide: Risk and Protective Factor Profiles for Bullies, Victims, Bully-Victims and the Uninvolved.

Bullying is closely associated with suicide. This study validates mixed evidence on whether young bullies, victims, bully-victims, and those uninvolved in bullying differ in suicidality, risk, protective factor profiles, and predictors of suicide. A total of 2004 Hong Kong adolescents and young adults completed the Hong Kong Online Survey on Youth Mental Health and Internet Usage in 2018. Bullies, victims, and bully victims, as opposed to the uninvolved, were found to possess higher tendencies of suicidal thoughts and behaviors. They had more distinct rather than overlapping risk and protective factor profiles yet shared psychological distress and diagnosis of a psychiatric disorder as common predictors of suicide. The results indicate that suicide screening assessments and training to detect common suicide predictors can benefit youngsters regardless of their bullying involvement. From the discussion, group-specific interventions include restorative justice approaches to promote reintegration and help-seeking among bullies, peer, and professional support programs geared towards lowering victim isolation and equipping gatekeepers such as teachers with skills to connect with both bullies and victims.

The Association between COVID-19-Related Wellbeing with Materialism and Perceived Threat.

The ongoing coronavirus disease (COVID-19) pandemic has had a profound impact on people's wellbeing. Here, we proposed that an individual characteristic might be associated with wellbeing; that is, materialism. Specifically, we conducted three studies (total N = 3219) to examine whether people with high levels of materialism would experience poorer wellbeing (i.e., anxiety and depression, in the current case). The results showed that materialism was positively associated with depression (Studies 1A, 1B and 2) and anxiety (Study 2). Moreover, such a relationship was mediated by people's perceived threat of COVID-19 (Study 2). These findings were observed in both Chinese and American people. The findings are discussed in terms of their theoretical and practical contributions.

Dominate others, hurt self: Social dominance orientation predicts depression during the COVID-19 pandemic.

The ongoing coronavirus pandemic threatens physical and psychological health. We examined whether social dominance orientation (SDO), a preference for inequality among social groups, contributes to mental health during the pandemic. In particular, we predicted that people high in SDO would experience higher levels of depression than others low in SDO. Our results (N = 2008) showed that SDO was positively associated with depression. In addition, participants' perceived lifestyle changes moderated the association between SDO and depression. We also discuss the theoretical and practical implications of the current work.

Psychosomatic Symptoms and Neuroticism following COVID-19: The Role of Online Aggression toward a Stigmatized Group.

The present study investigated the effect of interpersonal mistreatment on the perpetrators' mental health. We proposed that the threat of COVID-19 will increase people's mental health problems through their on-line aggression toward stigmatized groups accused of spreading the disease and that there might be potential gender differences in such effects. We tested our predictions among a sample of U.S. residents (Study 1) and a large sample of Chinese residents living out of Hubei province (Study 2) during a heightened period of concern about COVID-19, February 2020. Specifically, we measured U.S. residents' on-line aggressive behaviors toward Chinese people (Study 1) and Chinese non-Hubei residents' on-line aggressive behaviors toward Hubei residents (Study 2) as well as their neuroticism (Study 1) and mental health states (Study 2). In line with our predictions, both studies showed that perceived infection of COVID-19 can induce on-line aggression toward stigmatized groups, thereby increasing people's mental health problems. Moreover, the relationship between COVID-19 vulnerability, on-line aggression, and psychosomatic symptoms was more prominent in men than in women. These results offer insights into people's responses toward COVID-19 and add to the understanding of people's mental and physical health during the epidemic stage of contagious diseases.

A Multilab Replication of the Ego Depletion Effect.

There is an active debate regarding whether the ego depletion effect is real. A recent preregistered experiment with the Stroop task as the depleting task and the antisaccade task as the outcome task found a medium-level effect size. In the current research, we conducted a preregistered multilab replication of that experiment. Data from 12 labs across the globe (N = 1,775) revealed a small and significant ego depletion effect, d = 0.10. After excluding participants who might have responded randomly during the outcome task, the effect size increased to d = 0.16. By adding an informative, unbiased data point to the literature, our findings contribute to clarifying the existence, size, and generality of ego depletion.

Under the Threat of an Epidemic: People with Higher Subjective Socioeconomic Status Show More Unethical Behaviors.

This research focused on the psychological impact of an epidemic. We conducted a cross-sectional survey and two empirical experiments to examine how an epidemic would influence unethical behaviors and how the effect differs in people of different subjective socioeconomic statuses. These studies consistently demonstrated that subjective socioeconomic status moderates the relationship between an epidemic and unethical behaviors. Specifically, the perceived severity of an epidemic positively predicts the unethical behaviors of people with a high socioeconomic status, but it does not predict the unethical behaviors of people with a low socioeconomic status. These findings elucidate the effects of epidemics and bring theoretical and practical implications.

Money and flexible generosity.

Previous research on money and prosociality has described a monotonic pattern, showing that money reduces generosity. The present research aimed to examine whether money differently impairs generosity when arising from altruistic versus egoistic motives. To this end, we employed economic games designed to study generosity (e.g., the Dictator game) and varied experimental currency (i.e., money vs. candy/food). The results (N = 850) showed that although money made people ignore others when others were not crucial for their future gain, generosity was not impacted when egoistic motives (Study 1: avoiding sanctions; Studies 2 and 3: building reputation) were present. In other words, although people in general showed flexible prosociality by adjusting their generosity level according to game type, this was much more strongly the case when money rather than candy/food was the currency. In addition, we demonstrate a boundary condition of money on flexible generosity, namely imbuing money with prosocial meaning (Study 3). Some implications are discussed.

Religious residue: Cross-cultural evidence that religious psychology and behavior persist following deidentification.

More than 1 billion people worldwide report no religious affiliation. These religious "nones" represent the world's third largest religion-related identity group and are a diverse group, with some having previous religious identification and others never identifying as religious. We examined how 3 forms of religious identification-current, former, and never-influence a range of cognitions, emotions, and behavior. Three studies using nationally representative samples of religious Western (United States), secular Western (Netherlands, New Zealand) and Eastern (Hong Kong) cultures showed evidence of a religious residue effect: Formerly religious individuals (i.e., religious "dones") differed from never religious and currently religious individuals in cognitive, emotional, and behavioral processes. Study 1 (n = 3,071) offered initial cross-cultural evidence, which was extended in a preregistered replication study that also included measures of charitable contribution (Study 2; n = 1,626). Study 3 (N = 31,604) found that individuals who deidentified were still relatively likely to engage in prosocial behavior (e.g., volunteering) after leaving religion. This research has broad implications for understanding changing global trends in religious identification and their consequences for psychology and behavior.

Ostracism Disrupts Self-Continuity.

We conducted six studies to test our hypotheses that ostracism disrupts self-continuity and that self-affirmation counters ostracism's negative influence on self-continuity. Participants who experienced more ostracism in their daily lives (Study 1), imagined being ostracized (Studies 2 and 5), recalled a past ostracism experience (Studies 3 and 6), and were ostracized in a ball-tossing game (Study 4) reported lower levels of self-continuity than their counterparts. Moreover, neither violations of expectation nor negativity of the experience was sufficient in decreasing self-continuity (Study 5). Finally, self-affirmation weakened the negative effect of ostracism on self-continuity (Study 6). Taken together, our findings provide converging causal evidence for our hypotheses and provide novel insights for the literature on how daily interpersonal interactions influence individuals' sense of an enduring self. In addition, the moderation of self-affirmation reported in our research indicates an effective approach to diminishing the negative influence of ostracism.

The L-DOPA/Dopamine Pathway Transgenerationally Regulates Cuticular Melanization in the Pea Aphid Acyrthosiphon pisum.

Maternal phenotypic regulations between different generations of aphid species help aphids to adapt to environmental challenges. The pea aphid Acyrthosiphon pisum has been used as a biological model for studies on phenotypic regulation for adaptation, and its alternative phenotypes are typically and physiologically based on maternal effects. We have observed an artificially induced and host-related maternal effect that may be a new aspect to consider in maternal regulation studies using A. pisum. Marked phenotypic changes in the cuticular melanization of daughter A. pisum were detected via tyrosine hydroxylase knockdown in the mothers during their period of host plants alternations. This phenotypic change was found to be both remarkable and repeatable. We performed several studies to understand its regulation and concluded that it may be controlled via the dopamine pathway. The downregulation and phenotypes observed were verified and described in detail. Additionally, based on histological and immunofluorescence analyses, the phenotypic changes caused by cuticular dysplasia were physiologically detected. Furthermore, we found that this abnormal development could not be reversed after birth. Transcriptome sequencing confirmed that this abnormal development represents a systemic developmental failure with numerous transcriptional changes, and chemical interventions suggested that transgenerational signals were not transferred through the nervous system. Our data show that transgenerational regulation (maternal effect) was responsible for the melanization failure. The developmental signals were received by the embryos from the mother aphids and were retained after birth. APTH RNAi disrupted the phenotypic determination process. We demonstrate that non-neuronal dopamine regulation plays a crucial role in the transgenerational phenotypic regulation of A. pisum. These results enhance our understanding of phenotyping via maternal regulation in aphids.

Superficially Similar Adaptation Within One Species Exhibits Similar Morphological Specialization but Different Physiological Regulations and Origins.

Animals have developed numerous strategies to contend with environmental pressures. We observed that the same adaptation strategy may be used repeatedly by one species in response to a certain environmental challenge. The ladybird Harmonia axyridis displays thermal phenotypic plasticity at different developmental stages. It is unknown whether these superficially similar temperature-induced specializations share similar physiological mechanisms. We performed various experiments to clarify the differences and similarities between these processes. We examined changes in the numbers and sizes of melanic spots in pupae and adults, and confirmed similar patterns for both. The dopamine pathway controls pigmentation levels at both developmental stages of H. axyridis. However, the aspartate-ß-alanine pathway controls spot size and number only in the pupae. An upstream regulation analysis revealed the roles of Hox genes and elytral veins in pupal and adult spot formation. Both the pupae and the adults exhibited similar morphological responses to temperatures. However, they occurred in different body parts and were regulated by different pathways. These phenotypic adaptations are indicative of an effective thermoregulatory system in H. axyridis and explains how insects contend with certain environmental pressure based on various control mechanisms.

Life lacks meaning without acceptance: Ostracism triggers suicidal thoughts.

Eleven studies (N = 2,254; 2 preregistered) examined whether ostracism would trigger suicidal thoughts and whether perceived meaning in life would account for this effect. The feeling of ostracism was induced via recalling a past experience (Studies 1a, 1c, 2c, and 3b), imagining a future experience (Studies 1d, 1e, and 2b), engaging in an online real-time interaction (Studies 1b and 2d), or receiving bogus personality feedback (Study 3a). Across all 11 studies, ostracism increased suicidal thoughts. Study 1a found that ostracism increased implicit associations of "death" and "me" relative to "life" and "me" on the Implicit Association Test of Suicide (Nock et al., 2010). In Study 1b, ostracized participants showed more suicidal thoughts in imagined stressful situations than did included participants. Studies 1c, 1d, and 1e further showed that ostracism increased explicit suicidal thoughts compared with both inclusion and neutral experiences. Furthermore, we found that perceived meaning in life accounted for ostracism's effect on suicidal thoughts (Studies 2a and 2b), even after controlling for depressive affect (Study 2c). In Study 2d, a preregistered study, we directly compared the contributions of perceived meaning in life and the 4 basic needs and mood proposed in William's (2007, 2009) ostracism framework, and we found that perceived meaning in life had a distinct mediating role in the ostracism-suicidal thinking link. Finally, Studies 3a and 3b found that self-affirmation exercises reduced suicidal thoughts following ostracism. Life lacks meaning without social connection, thereby activating suicidal thoughts.
