远距离规则的内隐学习使用了何种记忆存储器：来自神经网络模拟的证据

关于远距离规则的知识是如何被内隐学习的,研究尚未得出结论。该研究通过采用和人类被试相同的实验材料和程序,考察了简单循环网络模型（SRN）对两种汉语声调远距离规则——倒映和逆行规则的内隐学习。结果发现：1.在广泛的参数范围上,SRN能够学会倒映和逆行规则,表明模型的记忆缓冲器可以模拟人类远距离规则的内隐学习;2.SRN对倒映规则的学习比对逆行规则的学习更好,表明在功能上远距离规则的内隐学习可能优先使用了先进先出的记忆存储器及信息加工模式。该研究为探究远距离规则内隐学习的机制提供了新的证据和视角。     

Discrimination threshold for haptic volume perception of fingers and phalanges

Humans exhibit a remarkable ability to discriminate variations in object volume based on natural haptic perception. The discrimination thresholds for the haptic volume perception of the whole hand are well known, but the discrimination thresholds for haptic volume perception of fingers and phalanges are still unknown. In the present study, two psychophysical experiments were performed to investigate haptic volume perception in various fingers and phalanges. The configurations of both experiments were completely dependent on haptic volume perception from the fingers and phalanges. The participants were asked to blindly discriminate the volume variation of regular solid objects in a random order by using the distal phalanx, medial phalanx, and proximal phalanx of their index finger, middle finger, ring finger, and little finger. The discrimination threshold of haptic volume perception gradually decreases from the little finger to the index finger as well as from the proximal phalanx to the distal phalanx. Overall, both the shape of the target and the part of the finger in contact with the target significantly influence the precision of haptic perception of volume. This substantial data set provides detailed and compelling perspectives on the haptic system, including for discrimination of the spatial size of objects and for performing more general perceptual processes.

Moral Emotions Toward Others at Work and Implications for Employee Behavior: a Qualitative Analysis Using Critical Incidents

We propose a theoretical framework for and, via critical incidents, inductively investigate (a) the situations that trigger moral emotions toward others at work and (b) worker responses to these situations. Critical incidents were collected from a heterogeneous sample of 423 workers. Participants described an incident that caused each of four moral emotions (gratitude, anger, admiration, and contempt) and their response. Incidents and responses were coded, and frequencies, differences across the moral emotions, and associations between incidents and responses were analyzed. Several morally relevant situations at work were found to trigger the moral emotions. Participants responded in ways that had implications for their performance and their own well-being. The incidents largely align with moral foundations theory (Haidt and Graham in Social Justice Research, 20, 98–116, 2007). Responses also show evidence for social exchange, social learning, and rational expectancy-based processes and behavior. The incidents specify several practices for managers and organizations to encourage and avoid. This was the first qualitative study of moral emotions at work and one of the few workplace studies to examine these emotions empirically. Several understudied factors and behavioral responses emerged.     

Superheroes for change: Physical safety promotes socially (but not economically) progressive attitudes among conservatives

Across two studies, we find evidence for our prediction that experimentally increasing feelings of physical safety increases conservatives' socially progressive attitudes. Specifically, Republican and conservative participants who imagined being endowed with a superpower that made them invulnerable to physical harm (vs. the ability to fly) were more socially (but not economically) liberal (Study 1) and less resistant to social change (Study 2). Results suggest that socially (but not economically) conservative attitudes are driven, at least in part, by needs for safety and security.     

Patient Moral Relativism in the <Emphasis Type="Italic">Zhuangzi</Emphasis>

Moral relativism familiar in the Western philosophical tradition, according to David Lyons, is either agent relativism (moral judgments are relative to the standards of the agent or the agent group) or appraiser relativism (moral judgments are relative to the standards of the appraiser(s) or appraiser group(s)). As Lyons has convincingly argued, they are both problematic. However, in the ancient Chinese Daoist classic, the Zhuangzi, we can find a different type of moral relativism, which I call patient relativism (moral judgments are relative to the patients’ standards). In the essay, I aim to argue in what sense Zhuangzi is a patient relativist and how patient relativism can avoid the problem of agent relativism and appraiser relativism.     

<Emphasis Type="Italic">Wh</Emphasis>-Questions,Universal Statements and Free Choice Inferences in Child Mandarin

This study investigated 5-year-old Mandarin-speaking children’s comprehension of wh-questions, universal statements and free choice inferences. Previous research has found that Mandarin-speaking children assign a universal interpretation to sentences with a wh-word (e.g., shei ‘who’) followed by the adverbial quantifier dou ‘all’ (Zhou in Appl Psycholinguist 36:411–435, 2013). Children also compute free choice inferences in sentences that contain a modal verb in addition to a wh-word and dou (Zhou, in: Nakayama, Su, Huang (eds.) Studies in Chinese and Japanese language acquisition: in honour of Stephen Crain. John Benjamins Publishing Company, Amsterdam, pp 223–235, 2017). The present study used a Question-Statement Task to assess children’s interpretation of sentences containing shei + dou, both with and without the modal verb beiyunxu ‘was allowed to’, as well as the contrast between sentences with shei + dou, which are statements for adults, versus ones with dou + shei, which are wh-questions for adults. The 5-year-old Mandarin-speaking child participants exhibited adult-like linguistic knowledge of the semantics and pragmatics of wh-words, the adverbial quantifier dou, and the deontic modal verb beiyunxu.     

Exposure,Agency, Perceived Threat,and Guilt as Predictors of Posttraumatic Stress Disorder in Veterans

Using a sample of 289 Iraq/Afghanistan veterans, this study examined the contributions of combat exposure, agency, perceived threat, and guilt to posttraumatic stress disorder (PTSD) symptoms. Regression analyses indicated the four variables (together with demographic variables) accounted for 79% of the variance in PTSD symptoms. Guilt was the most important predictor. In addition, guilt mediated between exposure and PTSD symptoms, perceived threat and PTSD symptoms, and agency and PTSD symptoms. Implications of these findings are discussed.     

Burger or yogurt? Indulgent consumption in impression management contexts

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public.
