社交媒体信任对重大突发公共卫生事件中公众网络谣言自治行为的影响

从社会心理学视角、以社交媒体信任为切入点,基于新冠肺炎疫情,考察公众在重大突发公共卫生事件中网络谣言自治行为的心理机制。采用问卷方法对963名成年居民进行调查。结果表明:(1)公众对官方社交媒体的信任既能直接促进公众的辟谣行为,也能通过增强公众对战胜疫情的信心产生间接影响;(2)公众对官方社交媒体的信任影响公众对自媒体的信任,但自媒体信任不能独立于官媒信任影响辟谣行为。因此,我国社交媒体存在着两个舆论场且官方舆论占主导地位,及时、有效的官方报道不仅能提高公众对战胜疫情的信心,也能促进公众网络谣言自治,进而实现网络谣言治理主体的多元化。     

慈悲冥想对利他行为的影响及其认知神经机制

慈悲冥想是一类旨在培养对自己和他人无条件的善意与同情的冥想练习方法, 主要包括慈心禅和怜悯禅修。诸多研究表明, 慈悲冥想可以促进练习者的利他行为。就影响机制而言, 慈悲冥想可能是通过增强对他人不幸的共情反应, 促进情绪的有效调控和提高亲社会动机来影响练习者的利他行为。未来的研究需选择更具生态效度的利他行为测量方法, 深入挖掘慈悲冥想影响利他行为的动态神经加工过程, 并尝试将慈悲冥想应用于临床群体。     

Malinowski's influence on Wittgenstein on the matter of use in language

Language use in social contexts plays a central role in the thinking of philosophers and social scientists. Evidence is presented that suggests that the anthropologist Bronislaw Malinowski influenced Ludwig Wittgenstein on the contexted use of language. It is also proposed that non-Western peoples have been a heuristic for Western thinkers on epistemological matters.     

Representation of memory for order of mental operations in cognitive tasks

Recent research shows that people learning a cognitive task acquire a memory for the order of operations applied, independent of the data to which those operations were applied. We designed two experiments to show how this sequence memory is represented. Experiment 1 compared predictions based on 3 possible sequence representation methods: composition, dyad transition, and associative chain. Latency and error results from a simple sequential task supported the associative chain representation. The associative links between operations presumably enhance performance by priming subsequent operations but do not operate in an all-or-none fashion. Experiment 2 explored whether transfer items that matched the first 2 rules and first 3 elements of a training item could bias participants toward executing a composed production learned during training. Latency and undetected error results were consistent with an associative chain representation but not with additional predictions made by the composition representation. These two experiments support the representation of operation sequences in memory as an associative chain.     

Role of sex in externally motivated self-touching gestures

Self-touching gestures can be externally induced by the verbal presentation of anxiety-inducing stimuli and the active discussion of a passage. The frequency of these self-touching gestures appears to be affected by the individual interacting with the topic, the type of discourse (listening or discussing), the type of stimulus (canaries or leeches), and the interaction between the types of discourse and stimulus. This study assessed these variables as well as the sex of the participant and the order of presentation of stimulus type, neither of which were statistically significant. Participants were read two passages, one about a topic (leeches) expected to produce anxiety and the other about a topic (canaries) not expected to do so, and asked to answer questions about the passages. The number of self-touches was counted by an observer in another room. Each participant had both types of discourse (listening and discussing) and both types of stimulus (canaries and leeches). There was no significant difference between the number of self-touches by participants with either the male or female reader. Discussion as a method of discourse was associated with a significantly greater number of self-touches than listening. The interaction between discourse type and stimulus type was also significant. The combination of the anxiety-producing stimulus and the active discourse (discussion) produced the highest average number of self-touches.     

Masked priming of prefixes and the influence of spelling-meaning consistency

Two experiments are reported which examined whether a prefixed word can be primed by a word sharing only the prefix letters in a masked priming paradigm. In addition the studies examined whether the size of the priming effect is influenced by the consistency with which a prefix letter pattern appears in real prefixed words. The ratio of real prefixed words to all words containing a prefix letter pattern was calculated and used to identify high-consistency prefixes, which are frequently used as prefixes (e.g., UN in UNHAPPY) and rarely appear as pseudoprefixes (e.g., UNCLE), and low-consistency prefixes, which appear in many pseudoprefixed words (e.g., DE in DESERT) but fewer truly prefixed words (e.g., DECODE). In Experiment 1, decision latencies for both types of prefixes were facilitated when real prefixed target words were preceded by real prefixed prime words in a short SOA masked priming paradigm, although the size of the priming effect for low-consistency prefixes was similar in size to that for orthographic controls. In Experiment 2, real prefixed target words were preceded by pseudoprefixed prime words. Facilitation in performance remained for high-consistency prefixes but was absent for low-consistency prefixes. These results support models of morphological processing that are sensitive to the statistical nature of the relationships between orthographic and semantic representations in a language.     

The evolution of domain-general mechanisms in intelligence and learning

For both humans and animals, domain-general mechanisms are fallible but powerful tools for attaining evolutionary goals (e.g., resources) in uncertain, novel environments that were not recurrent features of the environment of evolutionary adaptedness. Domain-general mechanisms interact in complex ways with domain-specific, information-encapsulated modules, most importantly by manipulating information obtained from various modules in attempting to solve novel problems. Mechanisms of general intelligence, particularly the executive functions of working memory, underlie analogical reasoning as well as the decontextualization processes that are central to human thought. Although there is a variety of evolved, special purpose learning devices, learning is also characterized by domain-general mechanisms that are able to achieve evolutionary goals by making novel and serendipitous associations with environmental cues.
