Individual differences in preference for risky behaviors during courtship

Engaging in risky behaviors is a sexual signalling strategy that men use to procure mates. The present study investigates men’s preferences for engaging in risky behaviors (along with women’s preferences for their male partner’s risky behavior) within dating couples. We investigated associations between relationship length, self-perceived attractiveness, sociosexuality orientation, and preference for risky behaviors in a sample of 256 couples. Results indicated that men had stronger preferences for risky behaviors than their partner’s ideal preference. Furthermore, relationship length was associated with a decline in women’s preference for their partner’s risk-taking, but not men’s preference for their own risk-taking. Self-perceived attractiveness was negatively associated with risk preference, and sociosexuality orientation was not directly related to risk preference. Female preferences for less intense male risky behaviors could reflect the need of paternal investment which is required for offspring care. Decreased male sexual signalling could account for lower preferences of risky behaviors in females who are involved in longer lasting romantic relationships.     

Changing “us” and hostility towards “them”—Implicit theories of national identity determine prejudice and participation rates in an anti-immigrant petition

National identity definitions determine who belongs to the national ingroup (e.g., “us Germans”) versus the “foreign” outgroup prone to hostile outgroup bias. We conducted five studies in two countries investigating if viewing the ingroup's national identity as fixed exacerbates the perceived divide between ingroup and outgroup and thus increases anti-immigrant hostility, while a malleable view blurs the divide and reduces anti-immigrant hostility. In a Prestudy (58 participants), an Implicit Theory of National Identity Scale was developed. In Studies 1 (154 participants) and 2 (390 participants), our scale predicted individuals’ prejudice and participation rates in a hypothetical referendum and a real petition against immigrants. In Studies 3 (225 participants) and 4 (225 participants), experimental evidence was obtained. Leading participants to believe that the definition of “a true compatriot” changes over time (rather than remaining the same) resulted in lower levels of prejudice and participation rates in an anti-immigrant petition.     

Getting Along and/or Getting Ahead: Differential HEXACO Personality Correlates of Likeability and Popularity among Adolescents

Getting along (i.e. to be liked) and getting ahead (i.e. to be popular) are two fundamental psychological motives that have important consequences for adolescents' well-being. Especially antisocial behavioural tendencies, which are less well covered by the Big Five than by the HEXACO model, have been shown to differentially predict likeability and popularity. In this study, possible differential relations between personality and likeability and popularity were investigated using the HEXACO Simplified Personality Inventory and sociometric measures of likeability and popularity among 552 (12 to 14 years old) adolescents. Results showed that agreeableness was the most important likeability predictor, whereas extraversion (positive), openness to experience, honesty-humility, and agreeableness (all three negative) were the most important popularity predictors. Facet-level analyses revealed that selected HEXACO facets (greed avoidance, fearfulness, social boldness, gentleness, prudence, perfectionism, aesthetic appreciation, and altruism) most strongly—and in opposite directions—differentiated in the prediction of likeability and popularity. Furthermore, none of the expected interactions but several masking and cancellation effects were observed. The results, which are also discussed in light of interpersonal circumplex, resource control strategies, hierarchical differentiation, and socioanalytic frameworks, suggest that—among early adolescents—differential personality predictors may make it difficult to both get along and get ahead. © 2020 The Authors.

工作记忆容量对显、隐性反馈的调节机制研究

本研究选择汉语量词为目标语结构,考察工作记忆容量对显、隐性两类反馈不同的调节机制。105名来自加拿大多伦多地区母语为英语的中学生被随机分为显性修正组、隐性重铸组和控制组,工作记忆容量采用听力跨度测试测量,显、隐性反馈的效果通过语法判断测试与引导性模仿测试分别进行评估。研究结果表明:(1)工作记忆容量有效调节了显性反馈,但对隐性反馈的调节作用不明显;(2)受试的工作记忆容量越高,对显性反馈的调节作用就越明显。     

不同加工水平对内隐记忆和外显记忆中生存加工的影响

记忆的生存加工优势主要指生存情景下的记忆成绩好于其他情景下记忆成绩的一种优势效应。实验1采用生存加工研究范式,结合内隐记忆和外显记忆测试方法,考察了生存加工在内隐记忆和外显记忆中的表现。实验2结合不同的词语评估时间,进一步考察了不同加工水平对内隐记忆和外显记忆中生存加工的影响。结果发现,在内隐记忆中没有表现出生存加工优势,但是在外显记忆中出现了生存加工优势效应,并且外显记忆中的生存加工优势会受到加工水平的影响。     

心理特权与大学生网络欺骗行为：有调节的中介效应

基于有限自制力理论探讨了心理特权对网络欺骗行为的影响及作用机制,采用心理特权量表、简版自我损耗量表、内隐人格理论量表和青少年网络偏差行为量表对738名大学生进行调查。结果发现：（1）在控制性别的条件下,心理特权显著正向预测网络欺骗行为;（2）心理特权通过自我损耗的中介作用间接预测网络欺骗行为;（3）内隐人格观调节心理特权通过自我损耗预测网络欺骗行为的前半路径,具体来说,相对于渐变论的大学生,实体论大学生的心理特权更多地通过自我损耗影响其网络欺骗行为。     

学科能力内隐观的普遍性及其年龄差异

数学、中文等学科能力,是先天固有不可改变的？,还是后天环境培养塑造,可以改变的？学生心目中对这类问题的主观想法,会直接影响学生的学习行为。其影响的范围,将取决于这类主观想法是否具有普遍性。比如,有些学生认为数学得父母遗传的,很难改变这些学生会不同同样认为中文、外语能力等,也是父母遗传的,变难改变？本研究了解是否有一主导思想,影响学生对不同学科能力的整体看法,同时也分析学生这类主观想法的年龄差异,。     

Self-Interest, Economic Beliefs, and Political Party Preference in New Zealand

This study explored the associations among income level, economic beliefs, and political party preference in terms of self-interest and ideological theories of party preference. Results from a survey of 487 New Zealand voters showed that the income levels and economic beliefs of supporters of the four major parties were organized along a single dimension: ACT supporters had the highest income and strongest neoliberal economic beliefs, followed closely by National supporters, whereas Alliance supporters had the lowest income and strongest welfare-state economic beliefs, followed by Labour supporters. However, the prediction of party preference from income and economic beliefs showed a different pattern: Income significantly predicted support for ACT, National, and Alliance; economic beliefs had the strongest influence on National and Labour support; and economic beliefs interacted with income to influence ACT and National support, but not Labour and Alliance support. The results suggest that voters who have gained or lost the most from the implementation of neoliberal policies—in this case, those with the highest and lowest incomes (i.e., ACT and Alliance supporters), respectively—form political party preference mainly from economic self-interest, whereas middle-income voters (i.e., National and Labour supporters) form party preference from ideological congruence. Moreover, higher status individuals may be more likely to use ideology to express self-interested motivation.     

新生儿情绪性语音加工的正性偏向——来自事件相关电位的证据

准确解码语音中的情绪信息能让个体更好地适应社会环境, 此能力对新生儿和婴儿尤其重要, 因为人类刚出生时听觉系统远比视觉系统发育得完善。虽然已有研究表明5~7月龄的婴儿能分辨不同情绪种类的语音, 但目前对新生儿的研究还非常少。人类是否在出生时即具有分辨不同种类情绪性语音的能力?新生儿对情绪的加工是否存在正性或负性偏向?本文选用odd-ball范式考察高兴、恐惧、愤怒三种韵律性语音在1~6天龄新生儿大脑中诱发的事件相关电位。实验1直接对比三种情绪性条件, 发现新生儿大脑的额区(F3和F4电极点)可以区分情绪性语音的正负性, 正性(高兴)语音诱发的“失匹配反应”幅度明显大于负性(愤怒和恐惧)语音。实验2采用偏差和标准刺激反转的odd-ball范式, 证实了实验1的结果并非源于三种情绪语音物理属性的差异。本文的结果提示, 新生儿大脑可自动辨别正性与负性情绪语音, 但尚不能将愤怒和恐惧两种负性语音区分开来。更重要的是, 高兴语音比两种负性语音诱发了更大的失匹配反应, 这一结果首次从神经学层面(电生理指标)为新生儿情绪性语音加工的正性偏向提供了证据。     

The effects of constant versus varied reinforcers on preference and resistance to change

Previous research has demonstrated that factors such as reinforcer frequency, amount, and delay have similar effects on resistance to change and preference. In the present study, 4 boys with autism made choices between a constant reinforcer (one that was the same food item every trial) and a varied food reinforcer (one that varied randomly between three possible food items). For all 4 boys, varied reinforcers were preferred over constant reinforcers, and they maintained higher response rates than constant reinforcers. In addition, when a distraction (a video clip) was introduced, responding maintained by varied reinforcers was more resistant to distraction than responding maintained by constant reinforcers. Thus, the present experiment extended the generality of the relation between preference and resistance to change to variation in reinforcer quality.
