On shame and the perceived credibility of sexual assault allegations

Despite the high incidence of sexual assault, doubt about allegations is common. Previous research suggests that victims expressing positive or no emotion are perceived as less credible than those expressing negative emotions. However, little is known about which specific negative emotional expressions contribute to credibility in this context. In two studies (N = 623), participants read a date rape vignette. The alleged victim's statement was paired with a picture of a female person expressing either shame, sadness, or no emotion. Participants rated the credibility of her account and completed a measure of rape myth acceptance. Controlling for rape myth acceptance, allegations were perceived as more credible when accompanied by an expression of shame versus sadness (a negative, low arousal control condition). It is critical to be aware of the shame-credibility bias in this context to intervene and support those who have experienced sexual assault.     

That looks easy! Evidence against the benefits of an easier criterion of success for enhancing motor learning

OPTIMAL theory predicts providing learners with a relatively easier criterion of success during practice enhances motor learning through increased self-efficacy, perceptions of competence, and intrinsic motivation. However, mixed results in the literature suggest this enhancement effect may be moderated by the number of successes achieved by learners practicing with the difficult criterion. To investigate this possibility, we manipulated quantity of practice to affect the absolute number of successes achieved by learners practicing with different success criteria. Eighty participants were divided into four groups and performed 50 or 100 trials of a mini-shuffleboard task. Groups practiced with either a large or a small zone of success surrounding the target. Learning was assessed 24 h after acquisition with retention and transfer tests. In terms of endpoint accuracy and precision, there were no learning or practice performance benefits of practicing with an easier criterion of success, regardless of the number of trials. This absence of a criterion of success effect was despite the efficacy of our manipulation in increasing the number of trials stopping within the zone of success, self-efficacy, perceptions of competence, and, for participants with 100 trials, intrinsic motivation. An equivalence test indicated that the effect of criterion of success was small, if existent. Moreover, at the individual level, intrinsic motivation did not predict posttest or acquisition performance. There were no benefits of easing the criterion of success on pressure, effort, accrual of explicit knowledge, or conscious processing. These data challenge key tenets of OPTIMAL theory and question the efficacy of easing criterion of success for motor learning.     

包容型氛围感知对员工建言的影响：心理安全感与惰性感知的双重路径

基于社会信息加工理论视角,通过对816名员工与其直接上级进行两时间点配对取样,探讨包容型氛围感知对员工建言的影响,以及心理安全感与惰性感知在两者关系中的作用机制。研究结果表明：员工包容型氛围感知对其建言行为起到促进作用,并通过心理安全感与惰性感知间接影响建言行为。研究结果不仅从理论上丰富与拓展了包容型氛围的效应研究,同时对实务界管理员工建言有一定的实践启示。     

Targeting Perceived Burdensomeness to Reduce Suicide Risk

Perceived burdensomeness (PB), defined by an intractable perception of burdening others, often reflects a false mental calculation that one’s death is worth more than one’s life and has been supported as a significant risk factor for suicide. Because PB often reflects a distorted cognition, it may serve as a corrective and promising target for the intervention of suicide. More work on PB is needed in clinically severe and in military populations. Sixty-nine (Study 1) and 181 (Study 2) military participants at high baseline suicide risk engaged in interventions targeting constructs relating to PB. Baseline and follow-up measures (at 1, 6, 12, 18, and 24 months) of suicidal ideation were administered, and various statistical approaches—including repeated-measures ANOVA, mediation analyses, and correlating standardized residuals—explored whether suicidal ideation decreased specifically by way of PB. In addition to utilizing a larger sample size, Study 2 included an active PB-intervention arm (N = 181) and a control arm (N = 121), who received robust care as usual. In both studies, participants improved considerably regarding baseline to follow-up suicidal ideation. The results of Study 2 mirrored those of Study 1, corroborating a potential mediational role for PB in treatment-related improvements in suicidal ideation in military participants. Effect sizes ranged from .07–.25. Interventions tailored at decreasing levels of perceived burdensomeness may be uniquely and significantly effective in reducing suicidal thoughts.     

Individual differences in patterns of developmental opportunity and constraint during COVID-19: Implications for longitudinal well-being

Individual differences in sociodemographic characteristics and trait-like perceptions of opportunities and constraints may shape how people respond to adversities such as the COVID-19 pandemic. However, little is known about how these factors combine to form multifaceted profiles of developmental opportunity and constraint or the implications of such profiles for longitudinal well-being following major life stressors. Using 1-year data from a national sample of U.S. adults (n = 293), we identified profiles based on relevant sociodemographic characteristics (age, socioeconomic status, chronic conditions, functional status) and trait-like perceptions of opportunity and constraints (perceived mastery, perceived constraints). Results of latent profile analyses showed that three common profiles emerged at pandemic onset (veridical opportunity, perceived constraints, perceived opportunity). Subsequent latent growth models showed that, despite reporting more sociodemographic constraints, the perceived opportunity profile exhibited better 1-year emotional well-being (positive and negative affect) during the pandemic than the perceived constraints profile. Findings advance the literature by identifying multifaceted individual differences in profiles of developmental opportunity and constraint and by showing these profiles have consequences for longitudinal well-being following the pandemic onset.     

The perceived vulnerability to disease scale: Cross-cultural measurement invariance and associations with fear of COVID-19 across 16 countries

Using cross-sectional data from N = 4274 young adults across 16 countries during the COVID-19 pandemic, we examined the cross-cultural measurement invariance of the perceived vulnerability to disease (PVD) scale and tested the hypothesis that the association between PVD and fear of COVID-19 is stronger under high disease threat [that is, absence of COVID-19 vaccination, living in a country with lower Human Development Index (HDI) or higher COVID-19 mortality]. Results supported a bi-factor Exploratory Structural Equation Modeling model where items loaded on a global PVD factor, and on the sub-factors of Perceived Infectability and Germ Aversion. However, cross-national invariance could only be obtained on the configural level with a reduced version of the PVD scale (PVD-r), suggesting that the concept of PVD may vary across nations. Moreover, higher PVD-r was consistently associated with greater fear of COVID-19 across all levels of disease threat, but this association was especially pronounced among individuals with a COVID-19 vaccine, and in contexts where COVID-19 mortality was high. The present research brought clarity into the dimensionality of the PVD measure, discussed its suitability and limitations for cross-cultural research, and highlighted the pandemic-related conditions under which higher PVD is most likely to go along with psychologically maladaptive outcomes, such as fear of COVID-19.

同伴拒绝与网络欺负的关系:愤怒的中介作用和感知匿名性的调节作用

网络欺负是随着互联网和移动通讯工具快速发展而产生的一种新的欺负形式。本研究旨在探讨同伴拒绝和网络欺负的关系以及愤怒在其中的中介作用和感知匿名性在其中的调节作用。以武汉市703名初中生为研究对象,采用问卷法对其同伴拒绝、网络欺负、愤怒和感知匿名性进行调查。结果表明：（1）在控制性别、年龄和每天上网时间后,同伴拒绝能够显著正向预测网络欺负;（2）愤怒在同伴拒绝和网络欺负的关系中起中介作用;（3）同伴拒绝对网络欺负的直接作用和愤怒在二者关系中的中介作用均会受到感知匿名性的调节,相对于感知匿名性水平低的个体,直接效应和中介效应在感知匿名性水平高的个体中更强。研究结果支持同伴拒绝和网络欺负的关系是一个有调节的中介模型,这对于制定青少年网络欺负的干预和预防措施具有重要意义。

Conceptual Organization and Memory in Nonretarded,Mildly Retarded,and Moderately Retarded Adults

Moderately retarded, mildly retarded, and nonretarded adults learned a list of 12 items from three categories to a criterion of 75% correct recall in a freerecall learning paradigm. Retention was measured 1 week later. The moderately retarded took more trials and had lower retention and clustering scores than the others. The mildly retarded took more trials and had lower retention than the nonretarded. The results violate Murdock's total time hypothesis (Cooper & Pantle, 1967) but support Mandler's (1967) contention that learning is enhanced by the mental capacity for organization.
