This study examines asymmetric preference reversals in intertemporal decision-making by comparing gain and loss contexts across choice and bidding tasks. In the gain context, participants preferred smaller, sooner (SS) rewards in choice tasks but assigned higher valuations to larger, later (LL) rewards in bidding tasks. Conversely, in the loss cont...

Chinese social psychology developed vigorously, and its scientific achievement showed explosive growth from 2000 to 2015.

Although previous studies identified a subgroup of social anxiety characterized by high impulsivity, it has not received sufficient attention. The purpose of this study was to explore social anxiety-impulsivity profiles and examine differences in aggression across profiles in a Chinese sample. The latent profile analysis was conducted to identify d...

Researchers have been looking for effective interventions to promote physical activity due to its great impact on both physical and mental health. In two studies, the current research investigated (1) whether evaluative conditioning could increase implicit attitudes toward exercise; (2) whether dual‐channel evaluative conditioning had a greater inf...

The relationship between parenting and self-control has received much attention from social and developmental psychologists. In a meta-analytic review, Li et al. (2019) identified a longitudinal association between parenting and subsequent self-control (P → SC) of r = .157, p < .001, and a longitudinal association between adolescent self-control an...

Based on relational leadership theory and self-determination theory, this study aims to investigate the relationship between leader-member exchange (LMX), job crafting, and flow at work among medical workers in the context of the COVID-19 pandemic. Participants in the study consisted of 424 hospital employees. The results showed that: (1) the LMX p...

Social factors cannot be neglected in predicting individual psychological health during a group crisis. Grounded in Vroom’s expectancy theory of motivation, the present research explores how and when institutional trust influences crisis related worries and griefs. Both the survey study (N = 234) and the experimental study (N = 111) were conducted...

In order to slow down the spread of the coronavirus, staying at home and avoiding going outside have been either strongly recommended or stringently enforced by governments all over the globe. Previous studies found that people with more collectivist orientation were more willing to comply with governmental guidelines and engage in preventive behav...

In the last few years, several models trying to calculate the biological brain age have been proposed based on structural magnetic resonance imaging scans (T1-weighted MRIs, T1w), using multivariate methods and artificial intelligence. We aimed to develop and validate a convolutional neural network (CNN) model for brain age prediction (PBA) using m...

Parental reflective functioning (PRF) is important for parenting and child development. To effectively assess PRF in Chinese parents, this study aimed to revise the Parental Reflective Functioning Questionnaire (PRFQ) for the Chinese context. The original Chinese version of the PRFQ (PRFQ-C) was revised by following psychometric validation procedur...

Authentic self is believed to be morally good. The current research proposes that the authentic self is also environmentally good. Across two studies, we tested the link between authenticity and pro-environmental attitude and behavior. In Study 1 (N=2,646), dispositional authenticity was found to be a predictor of pro-environmental behavior (PEB)....

Previous research demonstrated that childhood trauma was associated with self-control deficit from adolescence to adulthood. However, the underlying mechanism was not well understood. The present study aimed to examine the mediating effect of depletion sensitivity on the association between childhood trauma and self-control. This study recruited a...

This study investigated the relationship between death anxiety and experienced meaning in life. Six hundred and forty-eight Chinese college students were surveyed using the Death Anxiety Scale, the Prosocial Behavior Scale, and the Meaning in Life Scale. The results showed that death anxiety predicted experienced meaning through three pathways: the...

Females are considered to be at a disadvantage in spatial perspective taking. In this study, we examined whether stereotype threat negatively affects females’ spatial perspective-taking ability and executive functions. Then we explored which components of executive function play a mediating role in the effect of stereotype threat on females’ spatia...

Unlike the presentation format in a typical delay discounting task (e.g., “Would you prefer [A] US$4.3 today OR [B] US$7.5 in 22 days?”), Magen et al. inserted a zero to each alternative (e.g., “Would you prefer [A] US$4.3 today and US$0 in 22 days OR [B] US$0 today and US$7.5 in 22 days?”) and found this manipulation effectively reduced delay disc...

Background: Previous studies showed that anger, rather than sadness, created automatic intergroup bias in a minimal group context. Methods: The current research reports a single study (N = 99) aiming to replicate this finding and further to test whether the intergroup bias manifests as ingroup favoritism, outgroup derogation, or both. Results:...

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 acr...

Accumulating evidence indicates weak correlations between self-report and behavioral measures of the same construct. We suggest these weak correlations result from poor reliability of many behavioral measures and distinct response processes involved in the two measurement types. We also describe how researchers can benefit from appropriate use of t...

Abstract The ego depletion effect is one of the most famous phenomena in social psychology. A recent meta-analysis showed that after accounting for small-studies effects by using a newly developed method called PET-PEESE, the ego depletion effect was indistinguishable from zero. However, it is too early to draw such rushing conclusion because of th...

Self-other similarity judgment asymmetry refers to the tendency of people to judge others to be more similar to themselves than they judge themselves to be similar to others. This effect can be explained with both a cognitive model (Tversky, 1977) and a motivational explanation (Codol, 1987). Recent research has provided initial evidence for the co...

Initial exertion of self-control has been suggested to impair subsequent self-regulatory performance. The specific cognitive processes that underlie this ego depletion effect have rarely been examined. Drawing on the dual-process theory of executive control (Engle & Kane, ; Kane & Engle, ), the current meta-analysis revealed that initial self-contr...

All three critical points of the evolutionary explanation proposed by Maestripieri et al. may not withstand close scrutiny. Instead, there should be an alternative explanation that has nothing to do with genetic continuity, but stresses the rewarding property of attractiveness that results mainly from sociocultural value assignment and sexual exper...

The ego depletion effect has been examined by over 300 independent studies during the past two decades. Despite its pervasive influence, recently this effect has been severely challenged and asserted to be a fake. Based on an up-to-date meta-analysis that examined the effectiveness of each frequently used depleting task, we preregistered the curren...

The ego depletion effect has not been replicated by a recent project including 23 laboratories (N = 2141) in both English-speaking countries and non-English speaking countries (Hagger and Chatzisarantis, 2016). Although it provides seemingly robust evidence casting doubt on the existence of ego depletion, cautious attention should be paid to the ef...

The glucose view of self-control posited glucose as the physiological substrate of self-control “resource”, which results in three direct corollaries: 1) engaging in a specific self-control activity would result in reduced glucose level; 2) the remaining glucose level after initial exertion of self-control would be positively correlated with follow...

Recent research has shown that poverty directly impeded cognitive functions because the poor could be easily distracted by monetary concerns. We argue that this effect may be limited to functions relying on working memory. For functions that rely on proceduralized processes however, monetary concerns elicited by reminding of financial demands would...

People tend to judge others to be more similar to themselves than themselves are to others. This self-other similarity judgment asymmetry was often explained by a cognitive model developed by Tversky (1977). However, some findings were inconsistent with this model, implying there might be complementary processes underlying such asymmetry. Although...

It has been consistently demonstrated that initial exertion of self-control had negative influence on people's performance on subsequent self-control tasks. This phenomenon is referred to as the ego depletion effect. Based on action control theory, the current research investigated whether the ego depletion effect could be moderated by individuals'...

The ego depletion effect has been consistently replicated using the typical paradigm that consists of two consecutive tasks. However, striking contradiction exists in studies employing multiple tasks. The aim of the current study is to replicate previous studies following a similar procedure and design in a sample of participants from a non-western...

Decision makers often tend to escalate their commitment when faced with a dilemma of whether to continue a losing course of action. Researchers recently began to investigate the influence of discrete emotions on this decision tendency. However, this work has mainly focused on negative emotions and rarely considered positive emotions, to say nothing...

Researchers recently began to investigate the influences of discrete emotions on escalation of commitment. However, these works mainly focused on negative emotions and rarely considered positive emotions, to say nothing of comparing the effects of both of them simultaneously. The current research fills this gap by conducting three experiments to ex...

This study is among the first to examine how individuals’ cultural value orientations impact two separate stages of creativity: idea generation and idea implementation. A total of 247 Chinese employees completed questionnaires including I-C culture orientation, and their idea gereration behavior. Supervisor ratings of idea implementation were obtai...
