Follow My Eyes: The Gaze of Politicians Reflexively Captures the Gaze of Ingroup Voters

Studies in human and non-human primates indicate that basic socio-cognitive operations are inherently linked to the power of gaze in capturing reflexively the attention of an observer. Although monkey studies indicate that the automatic tendency to follow the gaze of a conspecific is modulated by the leader-follower social status, evidence for such effects in humans is meager. Here, we used a gaze following paradigm where the directional gaze of right- or left-wing Italian political characters could influence the oculomotor behavior of ingroup or outgroup voters. We show that the gaze of Berlusconi, the right-wing leader currently dominating the Italian political landscape, potentiates and inhibits gaze following behavior in ingroup and outgroup voters, respectively. Importantly, the higher the perceived similarity in personality traits between voters and Berlusconi, the stronger the gaze interference effect. Thus, higher-order social variables such as political leadership and affiliation prepotently affect reflexive shifts of attention

Systems microscopy approaches to understand cancer cell migration and metastasis

Cell migration is essential in a number of processes, including wound healing, angiogenesis and cancer metastasis. Especially, invasion of cancer cells in the surrounding tissue is a crucial step that requires increased cell motility. Cell migration is a well-orchestrated process that involves the continuous formation and disassembly of matrix adhesions. Those structural anchor points interact with the extra-cellular matrix and also participate in adhesion-dependent signalling. Although these processes are essential for cancer metastasis, little is known about the molecular mechanisms that regulate adhesion dynamics during tumour cell migration. In this review, we provide an overview of recent advanced imaging strategies together with quantitative image analysis that can be implemented to understand the dynamics of matrix adhesions and its molecular components in relation to tumour cell migration. This dynamic cell imaging together with multiparametric image analysis will help in understanding the molecular mechanisms that define cancer cell migration

Computers and people alike investigating the similarity-attraction paradigm in persuasive technology

\u3cp\u3eA study is presented that tests the relation between the (perceived) personality of an online interactive system and the personality of its user. We expected a system with a dominant interaction style to be more persuasive than a submissive one. Moreover, we expected people with dominant personalities to be persuaded more by a dominant system, while people with submissive personalities would be persuaded more by a submissive one. These expectations were tested in a study where participants were provided with automated persuasive messages that had either a dominant or a submissive style. Results support our hypotheses and show that the similarity-attraction paradigm can be extended to persuasive technologies. However, findings also show that the dominant system is perceived as less likable. Although it is hard to predict whether these effects occur in real-world settings, the current work could help creating technologies that adapt their persuasive messages to their users.\u3c/p\u3
