Numerical comparison of two-digit numbers: How differences at encoding can involve differences in processing

The study of two-digit numbers processing has recently gathered a growing interest. Here, we examine whether differences at encoding of two-digit oral verbal numerals induce differences in the type of processing involved. Twenty-four participants were submitted to a comparison task to 55. Differences at encoding were introduced by the use of dichotic listening and synchronous (synchronous condition) or asynchronous presentation (tens-first and units-first conditions) of the two-digit numerals' components. Our results showed that differences at the encoding stage of two-digit numerals involve: (1) different comparison processes (tens-first and units-first conditions: parallel comparison; synchronous condition: parallel and holistic comparison); and (2) differences in the weight of the tens- and units-effects. Therefore, attentional mechanisms determining at the encoding stage how much attention is paid to the two-digit numerals' components might account for the different types of processing found with two-digit numbers.     

“Seeing” the social roles of brands: How physical positioning influences brand evaluation

This paper investigates when the brand is promoting a specific social role (as a friend or as a leader), whether the physical position of a brand image in relation to the customer's image influences brand evaluations. Two studies reveal that the match between the promoted social role and the visual representations of the brand and customer in the ad layout improves evaluations. When the brand is promoted as a friend to its customers, consumers evaluate it more positively if the image of the brand is located horizontally and near to the image of the customer. However, when the brand is promoted as a leader to its customers, consumers evaluate it more positively if the image of the brand is located above and far from the image of the customer.     

Advocates Speak Out on Adult Sexual Assault: A Unique Crime Demands a Unique Response

Research documents the challenges presented to victims of sexual assault whose cases move through the criminal justice system. One key vantage point from which to understand how survivors experience the criminal justice system is from the perspective of the crisis center advocates who work with them. Graduate student research teams conducted semistructured interviews with rape crisis advocates across one Northeastern state. The voices of crisis center advocates raise key points that might help in the development of new procedures and processes for how adult sexual assault cases are handled in the justice system.     

Determining transformation distance in similarity: Considerations for assessing representational changes a priori

The representational distortion (RD) approach to similarity (e.g., Hahn, Chater, & Richardson, 2003 Hahn, U., Chater, N. and Richardson, L. B. 2003. Similarity as transformation. Cognition, 87: 1–32.  [Google Scholar]) proposes that similarity is computed using the transformation distance between two entities. We argue that researchers who adopt this approach need to be concerned with how representational transformations can be determined a priori. We discuss several roadblocks to using this approach. Specifically we demonstrate the difficulties inherent in determining what transformations are psychologically salient and the importance of considering the directionality of transformations.     

Women and Men Go to University: Mathematical Background and Gender Differences in Choice of Field in Higher Education

Gender segregation in higher education is well documented. Female students major in mathematics, technology, and sciences less often than men, and they concentrate in humanities and social sciences. Using multinomial logit on the 6,139 applicants to Tel Aviv University in Israel in 1994, I examined the claim that one of the roots of gender segregation in higher education lies in course-taking patterns in high school. The main findings are as follows: Women are underrepresented among the applicants to the mathematics-related fields of study; mathematical background in high school is particularly effective in narrowing the gender gap in applying to selective and attractive, but not mathematically related, fields of study at the university; women rely on high qualifications more than men when applying to selective and male-dominated fields of study. Several explanations of the findings will be discussed.     

Rethinking barriers: a novel conceptualization of exercise barriers in cancer survivors

Previous research suggests different types of barriers may demonstrate different relationships with intention to engage in health behaviors. This study explored global, practical, and health-related barriers’ relationships with exercise intention and behavior among cancer survivors. The mediating role of intention in the barriers-behavior relationships was also evaluated. Cancer survivors (N = 152) completed self-report measures of exercise barriers, intention, and behavior at baseline and of exercise behavior two months later. Global barriers were negatively related (p < .01) and practical and health-related barriers were unrelated (ps ≥ .07) to exercise intention. Global and practical barriers were negatively related (ps < .01) and health-related barriers were unrelated (p = .48) to subsequent exercise behavior. Exercise intention did not mediate any barriers-behavior relationships. Results suggest that global and practical barriers should be targeted in barriers reduction interventions and highlight the intention-behavior gap problem. Future research should explore multidimensionality of barriers for other health behaviors.     

Evolved navigation theory and horizontal visual illusions

Environmental perception is prerequisite to most vertebrate behavior and its modern investigation initiated the founding of experimental psychology. Navigation costs may affect environmental perception, such as overestimating distances while encumbered (Solomon, 1949). However, little is known about how this occurs in real-world navigation or how it may have evolved. We manipulated the most commonly navigated surfaces with a non-intuitive cost derived from evolved navigation theory. Observers in realistic settings unknowingly overestimated horizontal distances that contained a risk of falling and did so by the relative degree of falling risk. This manipulation produced previously unknown, large magnitude illusions in everyday vision in the environments most commonly navigated by humans. These results bear upon predictions from multiple fundamental theories of visual cognition.     

社会合作信息对距离知觉的影响

为探讨社会合作信息对距离知觉的影响,本研究通过两个实验,采用动态追逐场景,对两个追逐者之间的交互模式(或合作或单独追逐同一目标)与追逐目标的存在与否进行了操作。结果发现,相比随机运动和单独追逐,存在合作关系的两个追逐者间的距离被知觉得更远,即存在距离的扩张效应(实验1),且该效应不能由底层的物理特征所解释(实验2)。该结果揭示,社会合作信息使得知觉距离被扩张,其可帮助理解视觉的适应性机制。     

绿色生活方式的结构与测量

基于前人研究,结合对241份访谈问卷进行内容分析,构建绿色生活方式由知、情、意、行四维度组成的理论假设,并依照该理论初步编制绿色生活方式量表。采用调查法回收有效问卷1051份,结果显示:量表的 Cronbach α系数为0.919,分半信度系数为0.876,0.868; 量表与各维度均存在显著的中高等相关,各维度间存在显著的中低等相关; 探索性因素分析的结果与理论构想基本一致,验证性因素分析结果表明模型拟合度良好; 此外,量表能较好区分环境态度与环保行为有不一致倾向的个体。因此,本研究制定的绿色生活方式量表具有较好的信效度,并可为区分“言行一致”或“言行不一”的个体提供一定参考。
