Beyond genetics in Mental Rotation Test performance: The power of effort attribution

This study compares the effects on Mental Rotation Test (MRT) performance of instructions that stress the importance of (a) personal effort, and (b) genetically driven ability. A total of 120 high-school students were assigned to three groups, and administered two sub-tests of the MRT. Between the first and second sub-tests, the groups received one of the following instructions: effort (“anyone can succeed in this task by putting in effort”), ability (“performance on the test depends on genetic determinants”), and neutral for control (“this is an important test used in many countries”). We predicted that effort but not ability instructions would affect performance. Results confirmed the prediction and showed that, after controlling for baseline performance, the effort group outperformed the ability and control groups, which did not differ from each other. Discussion focuses on the mechanisms implied in believing ability to be genetically determined or experientially driven.     

Effects of Priming Social Goals on Personal Interest in Television News

Research indicates that personal interests drive news consumption, such that individuals neglect news items that are not of obvious personal relevance. This study tested whether an extrinsic social goal might increase personal interest in news through increased acquisition of, and perceived attention to news information, irrespective of pre-existing interest in the given topic. Results showed the prime increased information acquisition, as well as perceived attention to news. The prime also worked directly and indirectly through perceived attention to influence news interest in the predicted direction. Applications of findings for news teases and other promotional messages are considered.     

科学、技艺、技术:中国农业从物质到知识的穿越

中国农业在中国农政管理系统中是治国之本,该系统兼容地方文化多样性,扎根社会网络,对科学、技艺、技术的知识与实践产生了积极作用。在19世纪之前,几乎没有任何西方国家在促进农业生产和传播农业知识方面有所作为,中国却从宋代开始已经全面着手,政府发挥各级官员、文人学士、地主作者、农民和工匠的综合作用,鼓励官民合作,发展先秦以来的儒家伦理政治、伦理社会秩序和伦理道德民俗,更新了中国农业国家的知识系统与宇宙观。发展这一方向的研究成果,能够增加我们对科学与规律的理解,而它不仅存在于中国,也普遍地存在于人类社会的前现代时期之中。     

Learning to read: Evidence on the distinction between decoding and comprehension skills

The paper focuses on the importance of distinguishing between decoding and comprehension skills in reading. This distinction can also be applied to the study of precursors of reading and of the first phases of reading acquisition. The reconsideration of a 15-year research program shows evidence and implications of such a dissociation. In particular, the paper reviews psychometric research concerning reading performance in first and second grade, research on precursors of reading, the effects of early programs devoted to develop reading abilities. Decoding and comprehension reading components appear at least partially separated, related to different underlying cognitive abilities, differently sensitive to enrichment programs.     

Congruency as a nonspecific perceptual property contributing to newborns' face preference

Past research has shown that top-heaviness is a perceptual property that plays a crucial role in triggering newborns' preference toward faces. The present study examined the contribution of a second configural property, congruency , to newborns' face preference. Experiments 1 and 2 demonstrated that when embedded in nonfacelike stimuli, congruency induces a preference of the same strength as that induced by facedness. Experiments 3 and 4 demonstrated that the attentional biases toward facedness and congruency produce a cumulative effect on newborns' visual preferences according to an additive model. These findings were extended by those of Experiment 5, showing that the additive model holds true when congruency is added to top-heaviness in nonfacelike stimuli displaying more elements in the upper portion.     

Every unsuccessful problem solver is unsuccessful in his or her own way: affective and cognitive factors in proving

It is widely recognized that purely cognitive behavior is extremely rare in performing mathematical activity: other factors, such as the affective ones, play a crucial role. In light of this observation, we present a reflection on the presence of affective and cognitive factors in the process of proving. Proof is considered as a special case of problem solving and the proving process is studied adopting a perspective according to which both affective and cognitive factors influence it. To carry out our study, we set up a framework where theoretical tools coming from research on problem solving, proof and affect are present. The study is performed within a university course in mathematics education, where students were given a statement in elementary number theory to be proved and were asked to write down their proving process and the thoughts that accompanied this process. We scrutinize the written protocols of two unsuccessful students, with the aim of disentangling the intertwining between affect and cognition. In particular, we seize the moments in which beliefs about self and beliefs about mathematical activity shape the performance of our students.

A social network scorecard to monitor knowledge flows across communication media

This paper describes the application of a scorecard, based on social network analysis, to monitor the evolution of knowledge flows. This scorecard helps organizations to identify new ways to optimize knowledge flows by combining communication media that match their working environments. Three case studies were conducted: one within an Italian Research Centre, and two within U.S.-based Research and Education Centres. The interactions of members of these business communities were observed by monitoring multiple communication media over time. This is a departure from the common practice of using only e-mail communications to describe social networks. The goal of this paper is to answer the following question: does e-mail alone represent an accurate approximation of the social network? The results suggest that a better approximation can be found by monitoring multiple media: e-mail, chat, telephone, social networking websites, and face-to-face interactions.
