We investigate the emergence of iconicity, specifically a bouba‐kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of (a) participant dyads who played an interactive communicative game and (b) individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection (as opposed to by guided variation). 相似文献

Knowledge about the mechanisms underlying canine vision is far from being exhaustive, especially that concerning post-retinal elaboration. One aspect that has received little attention is motion perception, and in spite of the common belief that dogs are extremely apt at detecting moving stimuli, there is no scientific support for such an assumption. In fact, we recently showed that dogs have higher thresholds than humans for coherent motion detection (Kanizsar et al. in Sci Rep UK 7:11259, 2017). This term refers to the ability of the visual system to perceive several units moving in the same direction, as one coherently moving global unit. Coherent motion perception is commonly investigated using random dot displays, containing variable proportions of coherently moving dots. Here, we investigated the relative contribution of local and global integration mechanisms for coherent motion perception, and changes in detection thresholds as a result of repeated exposure to the experimental stimuli. Dogs who had been involved in the previous study were given a conditioned discrimination task, in which we systematically manipulated dot density and duration and, eventually, re-assessed our subjects’ threshold after extensive exposure to the stimuli. Decreasing dot duration impacted on dogs’ accuracy in detecting coherent motion only at very low duration values, revealing the efficacy of local integration mechanisms. Density impacted on dogs’ accuracy in a linear fashion, indicating less efficient global integration. There was limited evidence of improvement in the re-assessment but, with an average threshold at re-assessment of 29%, dogs’ ability to detect coherent motion remains much poorer than that of humans. 相似文献

The aim of this study was to explore whether children with and without learning difficulties use orthographic rules to write words. To study this, two types of tasks from the Early Grade Writing Assessment (EGWA) test were used: (1) a dictation task which included pseudowords with an implicit orthographic rule; and (2) a dictation task which included words with arbitrary, unregulated orthography. An initial sample of 1,447 students from grades 1 to 3 of elementary school was selected. The results showed that the variables task type and grade were significant when explaining the differences found between the groups. These findings are discussed from the perspective of the orthographic representations self-teaching hypothesis as related to the orthographic depth hypothesis, associated with the orthographic transparency of Spanish. 相似文献

Attention is biased towards threat-related stimuli. In three experiments, we investigated the mechanisms, processes, and time course of this processing bias. An emotional flanker task simultaneously presented affective or neutral pictures from the international affective picture system database either as central response-relevant stimuli or surrounding response-uninformative flankers. Participants’ response times to central stimuli was measured. The attentional bias was observed when stimuli were presented either for 1500?ms (Experiment 1) or 500?ms (Experiment 2). The threat-related attentional bias held regardless of the stimuli competing for attention even when presentation time was further reduced to 200?ms (Experiment 3). The results indicate that automatic and controlled mechanisms may interact to modulate the orientation of attention to threat. The data presented here shed new light on the mechanisms, processes, and time course of this long investigated by still largely unknown processing bias. 相似文献

Moral (dis)engagement with anthropogenic climate change in online comments on newspaper articles 下载免费PDF全文

Anthropogenic climate change (ACC) is widely acknowledged to be morally significant, but little is known about everyday moralising around ACC. We addressed this gap via quantified thematic analysis of 300 online comments to British newspaper articles on ACC, drawing on Bandura's moral disengagement theory. Moral disengagement through denial of ACC was widespread. Other disengagement strategies, such as palliative comparison and diminishing agency, occurred less often. There was also some moral engagement, most often through assertions of the existence of ACC and/or its harmful effects. Moral disengagement was significantly more common in comments on right wing than left wing newspapers, whereas the opposite was true of moral engagement. Although Bandura's framework provided a useful starting point to make sense of ACC moralising, it did not capture moral concerns that extended beyond its “harm/care” remit. In particular, many “denial” comments included a “dishonesty” discourse, whereby ACC proponents were accused of deception for ulterior motives. To classify this discourse as moral disengagement obscures its engagement with a different set of moral issues around trust and honesty. We suggest that Bandura's theory represents one possible “moral landscape” around ACC and could be extended to encompass a broader range of moral concerns. 相似文献

The notion of a mental time-line (i.e., past corresponds to left and future corresponds to right) supports the conceptual metaphor view assuming that abstract concepts like “time” are grounded in cognitively more accessible concepts like “space.” In five experiments, we further investigated the relationship between temporal and spatial representations and examined whether or not the spatial correspondents of time are unintentionally activated. We employed a priming paradigm, in which visual or auditory prime words (i.e., temporal adverbs such as yesterday, tomorrow) preceded a colored square. In all experiments, participants discriminated the color of this square by responding with the left or the right hand. Although the temporal reference of the priming adverb was task irrelevant in Experiment 1, visually presented primes facilitated responses to the square in correspondence with the direction of the mental time-line. This priming effect was absent in Experiments 2, 3, and 5, in which the primes were presented auditorily and the temporal reference of the words could be ignored. The effect, however, emerged when attention was oriented to the temporal content of the auditory prime words in Experiment 4. The results suggest that task demands differentially modulate the activation of the mental time-line within the visual and auditory modality and support a flexible association between conceptual codes. 相似文献

Research on the impact of letter transpositions that arise across morpheme boundaries has yielded conflicting results. These results have led to the suggestion that a cross-linguistic difference may exist in the recognition of Spanish and English words. In two masked-priming experiments run on separate groups of Spanish and English speakers, we tested this hypothesis by comparing the impacts of primes with letter transpositions that arose within morphemes or across morpheme boundaries on the recognition of identical or near-identical Spanish–English cognate targets. The results showed transposed-letter benefits in both Spanish and English that were not modulated by the position of the transposed letter in the prime stimulus. Our findings therefore add to the growing body of literature suggesting that the transposed-letter benefit is not affected by the position of the transposed letters relative to the morpheme boundary, and they dispel previous suggestions that there might be a genuine difference in orthographic coding across the Spanish and English writing systems. 相似文献

This study is concerned with the definition of deviance and the processes of constructing deviance in Stalinist societies. Deviances created by the state in these societies are analyzed, especially from functionalist and phenomenologist aspects and by applying Foucault's approach. Solzhenitsyn's Gulag Archipelago is used as a starting point for the analysis. In his work, Solzhenitsyn dwells at length on the “deviances” and the process of deviance construction in Stalinist Soviet Union. It is suggested that, in these societies, “total state deviance” fits in a desacralized, demodernized world view. Finally some consequences of this deviance image still at work are discussed. 相似文献

This study examines the extent to which male and female university students use verbal sexual coercion and physically forced sex on a dating partner and tests a theoretical model that specifies that corporal punishment, minor forms of neglect by parents, and sexual abuse increase the probability of sexually coercing and sexually assaulting a partner, and that this relationship is partly mediated by antisocial traits and behavior. A path analysis using multinomial logistic regression was used to test the fit of the model to a convenience sample of 13,877 students in 32 nations. Both male and female students perpetrate sexual coercion, but the rates are higher for males. For both men and women, each of the three forms of prior victimization studied were associated with an increased probability of antisocial behavior, which in turn was associated with an increased probability of verbally coercing and physically forcing sex. Most of the direct paths from victimization to sexual coercion were also statistically significant. Because relatively mild victimization such as corporal punishment and seemingly innocuous forms of neglect are highly prevalent, steps to reduce their prevalence could be an import step in primary prevention of sexual coercion. 相似文献
