Basic numerical capacities and prevalence of developmental dyscalculia: the Havana Survey

The association of enumeration and number comparison capacities with arithmetical competence was examined in a large sample of children from 2nd to 9th grades. It was found that efficiency on numerical capacities predicted separately more than 25% of the variance in the individual differences on a timed arithmetical test, and this occurred for both younger and older learners. These capacities were also significant predictors of individual variations in an untimed curriculum-based math achievement test and on the teacher scores of math performance over developmental time. Based on these findings, these numerical capacities were used for estimating the prevalence and gender ratio of basic numerical deficits and developmental dyscalculia (DD) over the grade range defined above (N = 11,652 children). The extent to which DD affects the population with poor ability on calculation was also examined. For this purpose, the prevalence and gender ratio of arithmetical dysfluency (AD) were estimated in the same cohort. The estimated prevalence of DD was 3.4%, and the male:female ratio was 4:1. However, the prevalence of AD was almost 3 times as high (9.35%), and no gender differences were found (male:female ratio = 1.07:1). Basic numerical deficits affect 4.54% of school-age population and affect more boys than girls (2.4:1). The differences between the corresponding estimates were highly significant (α < .01). Based on these contrastive findings, it is concluded that DD, defined as a defective sense of numerosity, could be a distinctive disorder that affects only a portion of children with AD.     

Testing the efficacy of a new procedure for reducing faking on personality tests within selection contexts

The authors propose a new procedure for reducing faking on personality tests within selection contexts. This computer-based procedure attempts to identify and warn potential fakers early on during the testing process and then give them a chance for recourse. Two field studies were conducted to test the efficacy of the proposed procedure. Study 1 participants were 157 applicants competing for 10 staff positions at a large university located in a southern city in the People's Republic of China. In Study 1, potential fakers received a warning message, whereas nonfakers received a nonwarning (control) message. Study 2 participants were 386 Chinese college students applying for membership of a popular student organization at the same university where Study 1 was conducted. In Study 2, the warning and control messages were randomly assigned to all applicants. Results showed some promise for the proposed procedure, but several practical issues need to be considered.     

Mental representations of attachment figures facilitate recovery following upsetting autobiographical memory recall

A growing literature shows that even the symbolic presence of an attachment figure facilitates the regulation of negative affect triggered by external stressors. Yet, in daily life, pernicious stressors are often internally generated--recalling an upsetting experience reliably increases negative affect, rumination, and susceptibility to physical and psychological health problems. The present research provides the first systematic examination of whether activating the mental representation of an attachment figure enhances the regulation of affect triggered by thinking about upsetting memories. Using 2 different techniques for priming attachment figure representations and 2 types of negative affect measures (explicit and implicit), activating the mental representation of an attachment figure (vs. an acquaintance or stranger) after recalling an upsetting memory enhanced recovery--eliminating the negative effects of the memory recall (Studies 1-3). In contrast, activating the mental representation of an attachment figure before recalling an upsetting memory had no such effect (Studies 1 and 2). Furthermore, activating the mental representation of an attachment figure after thinking about upsetting memories reduced negative thinking in a stream of consciousness task, and the magnitude of the attachment-induced affective recovery effects as assessed with explicit affect measures predicted mental and physical health in daily life (Study 3). Finally, a meta-analysis of the 3 studies (Study 4) showed that the regulatory benefits conferred by the mental representation of an attachment figure were weaker for individuals high on attachment avoidance. The implications of these findings for attachment, emotion regulation, and mental and physical health are discussed.     

Assessing the Role of Spirituality in Coping Among African Americans Diagnosed with Cancer

Spirituality plays an important role in cancer coping among African Americans. The purpose of this study was to report on the initial psychometric properties of instruments specific to the cancer context, assessing the role of spirituality in coping. Items were developed based on a theoretical model of spirituality and qualitative patient interviews. The instruments reflected connections to self, others, God, and the world. One hundred African American cancer survivors completed the instruments by telephone. The instruments showed adequate internal reliability, mixed convergent validity, discriminant validity, and interpretable factor structures.     

Pathogens promote matrilocal family ties and the copying of foreign religions

Within the same pathogen-stress framework as proposed by Fincher & Thornhill (F&T), we argue further that pathogen stress promotes matrilocal rather than patrilocal family ties which, in turn, slow down the process of modernity; and that pathogen stress promotes social learning or copying, including the adoption of foreign religions.

Acculturating to the Role of Tenure-Track Assistant Professor: A Family Systems Approach to Joining the Academy

The trajectory toward tenure is complex and arduous, and it requires one to balance attention among diverse and competing demands. It is not surprising that many newly appointed assistant professors report struggling with this process. Borrowing from family and ecological systems theories, we proffer a framework that may help junior faculty members—defined in this article as tenure-earning assistant professors—learn about the tenure-earning process as they navigate through the university system and beyond. We also describe and clarify the many parts of the tenure-earning process, including the roles, responsibilities, and multiple contexts that must be considered concurrently by junior faculty members as they progress through the stages of their tenure-earning appointment in the academy.     

The Compromise Effect in Choosing for Others

Most research into the compromise effect focuses on cognitive factors related to choosing for oneself. However, there are daily opportunities to make choices for others, from helping friends to buy merchandise to choosing souvenirs for relatives. Although it is a common practice, choosing for others is rarely discussed in the literature. Hence, this research is directed to determine whether (i) the compromise effect is greater for people choosing for others with whom one has a distant relationship compared to choosing for themselves, (ii) the decision maker's susceptibility to interpersonal relationships, accountability, and anticipated regret moderate the relationship between choosing for others versus choosing for themselves and the compromise effect, and (iii) the confidence of the decision maker mediates the relationship between deciding for others and the compromise effect. Five hypotheses are proposed and they are supported by the results from four experiments. Copyright © 2011 John Wiley & Sons, Ltd.
