All Giraffes Have Female‐Specific Properties: Influence of Grammatical Gender on Deductive Reasoning About Sex‐Specific Properties in German Speakers

Grammatical gender is independent of biological sex for the majority of animal names (e.g., any giraffe, be it male or female, is grammatically treated as feminine). However, there is apparent semantic motivation for grammatical gender classes, especially in mapping human terms to gender. This research investigated whether this motivation affects deductive inference in native German speakers. We compared German with Japanese speakers (a language without grammatical gender) when making inferences about sex‐specific biological properties. We found that German speakers tended to erroneously draw inferences when the sex in the premise and grammatical gender of the target animal agreed. An over‐generalization of the grammar–semantics mapping was found even when the sex of the target was explicitly indicated. However, these effects occurred only when gender‐marking articles accompanied the nouns. These results suggest that German speakers project sex‐specific biological properties onto gender‐marking articles but not onto conceptual representations of animals per se.     

Does sunshine prime loyal … or summer? Effects of associative relatedness on the evaluative priming effect in the valent/neutral categorisation task

After 30 years of research, the mechanisms underlying the evaluative priming effect are still a topic of debate. In this study, we tested whether the evaluative priming effect can result from (uncontrolled) associative relatedness rather than evaluative congruency. Stimuli that share the same evaluative connotation are more likely to show some degree of non-evaluative associative relatedness than stimuli that have a different evaluative connotation. Therefore, unless associative relatedness is explicitly controlled for, evaluative priming effects reported in earlier research may be driven by associative relatedness instead of evaluative relatedness. To address this possibility, we performed an evaluative priming study in which evaluative congruency and associative relatedness were manipulated independently from each other. The valent/neutral categorisation task was used to ensure evaluative stimulus processing in the absence of response priming effects. Results showed an effect of associative relatedness but no (overall) effect of evaluative congruency. Our findings highlight the importance of controlling for associative relatedness when testing for evaluative priming effects.     

记忆编码与特异性效应之间关系的ERP研究

通过事件相关电位（ERPs）探讨了在“学习–再认”模式条件下的记忆编码与特异性效应之间的关系。选择首要特异性特征为深、浅加工,次要特异性特征为高、低词频。研究结果表明,（1）行为数据支持了低频词的再认比高频词更精确;深加工的再认比浅加工更精确,并且深加工存在着显著的字频效应,浅加工没有显著的字频效应。（2）低频词比高频词有更大的ERP晚正成分（LPC）;在低频词条件下,存在着显著的相继记忆效应,随后再认正确的ERPs比随后再认不正确的ERPs更正。因此,加工方式和词频间接地影响着记忆编码的形成。     

Is there a memory profit after repeated learning of subject‐performed actions? Comparing direct and long‐term memory performance level as a function of age

Schatz, T.R., Spranger, T. & Knopf, M. (2010). Is there a memory profit after repeated learning of subject‐performed actions? Comparing direct and long‐term memory performance level as a function of age. Scandinavian Journal of Psychology 51, 465–472. The present two studies investigated the possibility for improvement and maintenance of episodic memory in young and older adults. In a first study, the performance‐enhancing effect of two separate as well as combined learning devices, enactive encoding and repeated learning, was tested. With a time lag of one week, four different series of 30 action phrases were encoded either verbally or by enacting them symbolically. Memory was assessed in four immediate free recall tests. In a second study, the maintenance of the memory profit was tested in an unexpected fifth session half a year later. As expected, there was a steady improvement of memory performance as a function of repeated learning in study one. This holds true regardless of age. In addition, enactive encoding led to a better memory performance than verbal encoding in both age groups. Moreover, younger adults outperformed the elderly regardless of type of encoding. The combination of the two learning devices was not efficient enough to eliminate aging effects in episodic memory. However, memory flexibility is demonstrated also in the elderly. In the long‐term follow‐up, maintenance of learning and memory could be found in all participant groups.     

汉语言语产生的语音加工机制

通过采用词图干扰范式的图形命名技术,系统控制启动词与目标词之间的语音关系,探讨汉语言语产生中语音加工的机制。实验一发现,目标语音在韵尾变化条件下具有显著的语音启动效应,表明汉语语音音节是在言语产生过程中生成的;实验二在启动语音与目标语音仅共有声母的情况下,发现了与实验一相同的模式、结果支持实验一的结论,即汉语语音音节是在言语产生过程中生成的,语音的加工过程是一个构建的过程而不是简单的音节提取过程。     

Iconicity and Diachronic Language Change

Iconicity, the resemblance between the form of a word and its meaning, has effects on behavior in both communicative symbol development and language learning experiments. These results have invited speculation about iconicity being a key feature of the origins of language, yet the presence of iconicity in natural languages seems limited. In a diachronic study of language change, we investigated the extent to which iconicity is a stable property of vocabulary, alongside previously investigated psycholinguistic predictors of change. Analyzing 784 English words with data on their historical forms, we found that stable words are higher in iconicity, longer in length, and earlier acquired during development, but that the role of frequency and grammatical category may be less important than previously suggested. Iconicity is revealed as a feature of ultra-conserved words and potentially also as a property of vocabulary early in the history of language origins.     

How sensitivity to provocation shapes encoding and interpretation of ambivalent scenes in an eye tracking study

ABSTRACT

Hostility bias is based on the attribution of intentionality, personality traits such as trait anger and sensitivity to provocation (SP), as well as gender. Eye-tracking studies have shown that, prior to the interpretation of everyday social encounters, people might pay attention to hostile and non-hostile cues differently depending on trait anger; however, little is known about the encoding patterns of individuals sensitive to provocation. We conducted two studies, one of which was on interpretation and the other on encoding. Study 1 (N = 75) found that people low in SP gazed significantly longer at non-hostile cues than at hostile cues. Study 2 (N = 197, 84 men) revealed a significant interaction for judgment of intentionality in ambiguous scenes between gender and both SP and trait-anger; SP, trait anger and intentionality were negatively related in females, whereas in males they were positively related, although the relationships themselves (simple effects) were non-significant.
