Lower, Slower, Louder: Vocal Cues of Sarcasm

Previous studies have examined verbal rather than vocal aspects of irony. The present study considers how vocal features may cue listeners to one form of irony--sarcasm. Speakers were recorded reading sentences in three conditions (nonsarcasm, spontaneous sarcasm, posed sarcasm) with the resulting utterances filtered to remove verbal content. Listeners (n = 127) then rated these filtered utterances on amount of sarcasm. Results indicated that listeners were able to discriminate posed sarcasm from nonsarcasm but not spontaneous sarcasm from nonsarcasm. An analysis of the vocal features of the utterances as determined by perceptual coding indicated that a slower tempo, greater intensity, and a lower pitch level were significant indicators of sarcasm.     

Countries with fewer males have more violent crime: marriage markets and mating aggression

Violent crimes (murders, rapes, and assaults) are substantially higher in countries with a relative scarcity of men according to research using INTERPOL data [Barber, 2000a]. This is a paradox given that males are more criminally violent and likely reflects increased direct mating competition. The present research sought to confirm and extend Barber's [2000a] finding, using murder data from the United Nations and homicides from World Health Organization that are of higher quality than the INTERPOL data, and using more rigorous controls. In addition to level of economic development, control variables included, income inequality, urbanization, population density, the number of police, and whether the country was a major center of illegal drug trafficking. Regression analyses with all controls found that killings in both data sets increased with declines in the male proportion of the population. The findings are discussed in terms of direct reproductive competition and alternative explanations are considered.     

The dark triad: Facilitating a short‐term mating strategy in men

This survey (N = 224) found that characteristics collectively known as the Dark Triad (i.e. narcissism, psychopathy and Machiavellianism) were correlated with various dimensions of short‐term mating but not long‐term mating. The link between the Dark Triad and short‐term mating was stronger for men than for women. The Dark Triad partially mediated the sex difference in short‐term mating behaviour. Findings are consistent with a view that the Dark Triad facilitates an exploitative, short‐term mating strategy in men. Possible implications, including that Dark Triad traits represent a bundle of individual differences that promote a reproductively adaptive strategy are discussed. Findings are discussed in the broad context of how an evolutionary approach to personality psychology can enhance our understanding of individual differences.

秩序线索对个体信任水平的影响

人类有追求规则、秩序的本能,有秩序的环境是否能提高人们的信任水平呢？本文的具身性研究思路将社会学中抽象的“秩序”具体化为任务操作,以197名大学生为被试,将其分为三组分别完成秩序程度不同的连线任务,然后通过投资博弈任务测量被试信任水平。结果显示,（1）秩序线索影响信任水平,强秩序线索能提高个体信任水平;（2）秩序线索对信任的影响因个体性别不同而表现出差异,秩序线索的差异只影响女性信任水平;不同秩序条件下的男性信任水平不存在显著差异。     

不同性别比和资源获取能力对未婚男性择偶标准的影响

本研究分别采用文字启动和图片启动两种方式,探讨不同性别比下男性择偶标准的动态变化。实验1和实验2的结果均显示:相比于男多女少启动,在女多男少启动下,男性对女性"好资源"的要求会明显升高。不同性别比启动和男性资源获取能力(而不是童年经济状况)在男性择偶标准上存在着交互效应。相比于男多女少启动,资源获取能力强的男性在女多男少启动下对女性好资源的要求会明显提高,而资源获取能力弱的男性在两种启动下对女性好资源的要求没有显著变化。结论:对资源获取能力强的男性而言,对女性"好资源"的偏好是择偶选择过多时所产生的奢侈需求。     

Social cues and verbal framing in risky choice

We examined how people use social and verbal cues of differing priorities in making social decisions. In Experiment 1, formally identical life – death choice problems were presented in different hypothetical group contexts and were phrased in either a positive or negative frame. The risk‐seeking choice became more dominant as the number of kin in an endangered group increased. Framing effects occurred only in a heterogeneous group context where the lives at risk were a mixture of kin and strangers. No framing effect was found when the same problem was presented in the context of a homogeneous group consisting of either all kin or all strangers. We viewed the framing effects to be a sign of indecisive risk preference due to the differential effects of a kinship cue and a stranger cue on choice. In Experiment 2, we presented the life – death problem in two artificial group contexts involving either 6 billion human lives or 6 billion extraterrestrial lives. A framing effect was found only in the human context. Two pre‐conditions of framing effects appear to be social unfamiliarity of a decision problem and aspiration level of a decision maker. In Experiment 3, we analyzed the direction of the framing effect by balancing the framing. The direction of the framing effect depended on the baseline level of risk preference determined by a specific decision context. Copyright © 2001 John Wiley & Sons, Ltd.     

The language used in describing autobiographical memories prompted by life period visually presented verbal cues,event-specific visually presented verbal cues and short musical clips of popular music

Here, we examined linguistic differences in the reports of memories produced by three cueing methods. Two groups of young adults were cued visually either by words representing events or popular cultural phenomena that took place when they were 5, 10, or 16 years of age, or by words referencing a general lifetime period word cue directing them to that period in their life. A third group heard 30-second long musical clips of songs popular during the same three time periods. In each condition, participants typed a specific event memory evoked by the cue and these typed memories were subjected to analysis by the Linguistic Inquiry and Word Count (LIWC) program. Differences in the reports produced indicated that listening to music evoked memories embodied in motor-perceptual systems more so than memories evoked by our word-cueing conditions. Additionally, relative to music cues, lifetime period word cues produced memories with reliably more uses of personal pronouns, past tense terms, and negative emotions. The findings provide evidence for the embodiment of autobiographical memories, and how those differ when the cues emphasise different aspects of the encoded events.     

Shared and distinct cue utilization for metacognitive judgements during reasoning and memorisation

Metacognitive research is dominated by meta-memory studies; meta-reasoning research is nascent. Accessibility – the number of associations for a stimulus – is a reliable heuristic cue for Feeling of Knowing when answering knowledge questions. We used a similar cue, subjective accessibility, for exposing commonalities and differences between meta-reasoning and meta-memory. In Experiment 1, participants faced solvable Compound Remote Associate problems mixed with unsolvable random word triads. We collected initial Judgement of Solvability (iJOS), final JOS (fJOS) and confidence. Experiment 2 focused on confidence, controlling for potential interactions among judgements. In Experiment 3, the participants memorised the same triads and rated Ease of Learning and Judgement of Learning. sAccessibility was associated with all judgements. Notably, it reliably predicted memory judgements and confidence in the provided solutions. However, it was unreliable for judging solvability (iJOS and fJOS). The findings highlight the importance of studying meta-reasoning for exposing the biasing factors in reasoning processes and for getting a broad perspective on metacognitive processes.     

求偶动机的心理效应

演化心理学认为人类的心理机能受到演化压力的塑造,性选择作为重要的演化动力因素,在人类心理机能的形成过程中扮演着重要角色。与性选择密切相连的求偶动机可以影响包括注意、知觉、记忆、决策及社会行为在内的一系列心理现象和行为,但求偶动机操控方法的混乱及研究过程中对文化和层级选择的忽视制约了这一领域工作的开展。进一步深化相关研究,以行为数据为基础,从神经、激素和基因层面建构立体的研究框架对于揭示背后机制有着重要作用。
