On the interactive influence of facial appearance and explicit knowledge in social categorization

Although people form impressions of others with ease, sometimes one's initial perceptions of individuals conflict with what one knows about them. Here, we aimed to investigate the process by which explicit knowledge about people interacts with initial perceptions on the basis of cues from facial appearance. Participants memorized the sexual orientations of men's faces wherein half of the targets were encoded with a sexual orientation opposite to their actual orientation. Subsequent categorization showed that perceivers favored appearance‐based information when temporally constrained but favored explicit knowledge about group membership with increased viewing time. Additionally, real‐time measures of participants' categorizations showed greater vacillation between appearance‐based cues and explicit knowledge as viewing time increased. These findings suggest that explicit knowledge does not simply overrule appearance‐based cues past a particular threshold but that the two may interact recurrently with top‐down knowledge directing attention and perception at later processing.

Maternal Intrusiveness,Family Financial Means,and Anxiety Across Childhood in a Large Multiphase Sample of Community Youth

Intrusive parenting has been positively associated with child anxiety, although examinations of this relationship to date have been largely confined to middle to upper middle class families and have rarely used longitudinal designs. With several leading interventions for child anxiety emphasizing the reduction of parental intrusiveness, it is critical to determine whether the links between parental intrusiveness and child anxiety broadly apply to families of all financial means, and whether parental intrusiveness prospectively predicts the development of child anxiety. This study employed latent growth curve analysis to evaluate the interactive effects of maternal intrusiveness and financial means on the developmental trajectory of child anxiety from 1st grade to age 15 in 1,121 children (50.7 % male) and their parents from the NICHD SECCYD. The overall model was found to provide good fit, revealing that early maternal intrusiveness and financial means did not impact individual trajectories of change in child anxiety, which were stable from 1st to 5th grade, and then decrease from 5th grade to age 15. Cross-sectional analyses also examined whether family financial means moderated contemporaneous relationships between maternal intrusiveness and child anxiety in 3rd and 5th grades. The relationship between maternal intrusiveness and child anxiety was moderated by family financial means for 1st graders, with stronger links found among children of lower family financial means, but not for 3rd and 5th graders. Neither maternal intrusiveness nor financial means in 1st grade predicted subsequent changes in anxiety across childhood. Findings help elucidate for whom and when maternal intrusiveness has the greatest link with child anxiety and can inform targeted treatment efforts.     

The Diagnostic Utility of Separation Anxiety Disorder Symptoms: An Item Response Theory Analysis

At present, it is not clear whether the current definition of separation anxiety disorder (SAD) is the optimal classification of developmentally inappropriate, severe, and interfering separation anxiety in youth. Much remains to be learned about the relative contributions of individual SAD symptoms for informing diagnosis. Two-parameter logistic Item Response Theory analyses were conducted on the eight core SAD symptoms in an outpatient anxiety sample of treatment-seeking children (N?=?359, 59.3 % female, M _Age?=?11.2) and their parents to determine the diagnostic utility of each of these symptoms. Analyses considered values of item threshold, which characterize the SAD severity level at which each symptom has a 50 % chance of being endorsed, and item discrimination, which characterize how well each symptom distinguishes individuals with higher and lower levels of SAD. Distress related to separation and fear of being alone without major attachment figures showed the strongest discrimination properties and the lowest thresholds for being endorsed. In contrast, worry about harm befalling attachment figures showed the poorest discrimination properties, and nightmares about separation showed the highest threshold for being endorsed. Distress related to separation demonstrated crossing differential item functioning associated with age—at lower separation anxiety levels excessive fear at separation was more likely to be endorsed for children ≥9 years, whereas at higher levels this symptom was more likely to be endorsed by children <9 years. Implications are discussed for optimizing the taxonomy of SAD in youth.     

Behavioral ethics for Homo economicus,Homo heuristicus,and Homo duplex

In this article we explore how assumptions about human nature may influence the ways one might try to promote ethical behavior in organizations. We summarize two common views of human nature in organizational research—Homo economicus and Homo heuristicus. We then extend these views by putting forward a third view of human nature initially proposed by Emile Durkheim—Homo duplex—which describes human beings as moving back and forth between a lower (individual) and higher (collective) level. We suggest that the Homo duplex view is uniquely equipped to account for variables of interest to organizational scholars because of its attention to a fundamental tension: People in organizations can be both selfish and groupish, and the balance between those tendencies influences the ethical profile of the organization in complex ways. We end with a discussion of the theoretical implications of the Homo duplex view for behavioral ethics researchers.     

Science Blogging: Networks,Boundaries and Limitations

There is limited research into the realities of science blogging, how science bloggers themselves view their activity and what bloggers can achieve. The ‘badscience’ blogs analysed here show a number of interesting developments, with significant implications for understandings of science blogging and scientific cultures more broadly. A functioning and diverse online community (with offline elements) has been constructed, with a number of non-professional and anonymous members and with boundary work being used to establish a recognisable outgroup. The community has developed distinct norms alongside a type of distributed authority and has negotiated the authority, anonymity and varying status of many community members in some interesting and novel ways. Activist norms and initiatives have been actioned, with some prominent community campaigns and action. There are questions about what science blogging—both in the UK and internationally—may be able to achieve in future and about the fragility of the ‘badscience’ community. Some of the highly optimistic hopes which have been associated with science blogging have not been realised. Nonetheless, the small group of bloggers focused on here have produced significant achievements with limited resources, especially when one considers this in the context of community values as opposed to some of the expectations attached to science blogging within scientific cultures more broadly. While the impacts of this science blogging community remain uncertain, the novel and potentially significant practices analysed here do merit serious consideration.     

Household pre‐purchase practices and online grocery shopping

This paper explores household pre‐purchase practices and their mediation by information and communications technologies (ICTs), specifically online grocery shopping. Drawing on practice theory, the impacts of ICTs on household grocery shopping behavior are conceptualized, and the concept of “front‐loading” is introduced. Emerging themes generated from 31 semi‐structured interviews conducted via Skype with Turkish consumers focusing on their experiences of online grocery practices are presented. To this end, the contribution of this paper is twofold. First, an understanding of the domestication of online grocery shopping and its affect on the dynamics of household decision making, information sharing, and responsibilities of tasks before the actual act of online shopping is developed. Second, how such pre‐purchase practices undertaken by consumers act as a catalyst of change at the industry level is appraised. Copyright © 2014 John Wiley & Sons, Ltd.     

Resources required for processing ambiguous complex features in vision and audition are modality specific

Processing multiple complex features to create cohesive representations of objects is an essential aspect of both the visual and auditory systems. It is currently unclear whether these processes are entirely modality specific or whether there are amodal processes that contribute to complex object processing in both vision and audition. We investigated this using a dual-stream target detection task in which two concurrent streams of novel visual or auditory stimuli were presented. We manipulated the degree to which each stream taxed processing conjunctions of complex features. In two experiments, we found that concurrent visual tasks that both taxed conjunctive processing strongly interfered with each other but that concurrent auditory and visual tasks that both taxed conjunctive processing did not. These results suggest that resources for processing conjunctions of complex features within vision and audition are modality specific.
