Emotional and deliberative reactions to a public crisis: Mad Cow disease in France

Although most theories of choice are cognitive, recent research has emphasized the role of emotions. We used a novel context--the Mad Cow crisis in France--to investigate how emotions alter choice even when consequences are held constant. A field study showed that individuals reduced beef consumption in months after many newspaper articles featured the emotional label "Mad Cow," but beef consumption was unaffected after articles featured scientific labels for the same disease. The reverse pattern held for the disease-related actions of a government bureaucracy. A lab study showed that the Mad Cow label induces people to make choices based solely on emotional reactions, whereas scientific labels induce people to consider their own probability judgments. Although the Mad Cow label produces less rational behavior than scientific labels, it is two to four times more common in the environment.     

Object onset and parvocellular guidance of attentional allocation

The parvocellular visual pathway in the primate brain is known to be involved with the processing of color. However, a subject of debate is whether an abrupt change in color, conveyed via this pathway, is capable of automatically attracting attention. It has been shown that the appearance of new objects defined solely by color is indeed capable of modulating attention. However, given evidence suggesting that the visual system is particularly sensitive to new onsets, it is unclear to what extent such results reflect effects of color change per se, rather than effects of object onset. We assessed attentional capture by color change that occurred as a result of either new objects appearing or already-present "old" objects changing color. Results showed that although new object onsets accrued attention, changing the color of old objects did not. We conclude that abrupt color change per se is not sufficient to capture attention.     

The closing of the theory of mind: A critique of perspective-taking

Theory of mind (ToM) is defined as the ability to attribute mental states to oneself and others and is often said to be one of the cornerstones of efficient social interaction. In recent years, a number of authors have suggested that one particular ToM process occurs spontaneously in that it is rapid and outside of conscious control. This work has argued that humans efficiently compute the visual perspective of other individuals. In this article, we present a critique of this notion both on empirical and theoretical grounds. We argue that the experiments and paradigms that purportedly demonstrate spontaneous perspective-taking have not as yet convincingly demonstrated the existence of such a phenomenon. We also suggest that it is not possible to represent the percept of another person, spontaneous or otherwise. Indeed, the perspective-taking field has suggested that humans can represent the visual experience of others. That is, going beyond assuming that we can represent another’s viewpoint in anything other than symbolic form. In this sense, the field suffers from the same problem that afflicted the “pictorial” theory in the mental imagery debate. In the last section we present a number of experiments designed to provide a more thorough assessment of whether humans can indeed represent the visual experience of others.

     

Mixed up about mixed worlds? Understanding Blackburn’s supervenience argument

Simon Blackburn’s supervenience argument—focusing on the mysterious “ban on mixed worlds”—is still subject to a variety of conflicting interpretations. In this paper, I hope to provide a defense of the argument that clarifies both the argument and the objections it must overcome. Many of the extant objections, I will argue, fail to engage the argument in its true form. And to counter the more compelling objections, it will be necessary to bring in additional argumentation that Blackburn himself does not clearly provide. One important upshot of this discussion is that moral realism is not the only target of the argument: it raises trouble for a variety of metaethical views wed to realist-friendly construals of moral evaluation. Rightly understood, this argument not only survives the prominent responses, but turns out to be more powerful than his critics and Blackburn himself have recognized.     

Prospective Relations between Overeating,Loss of Control Eating,Binge Eating,and Depressive Symptoms in a School-Based Sample of Adolescents

A sample of 353 community adolescents (grades 9 to 12, 57.6 % female) participated in a 2-wave longitudinal study of eating behaviors (overeating, loss of control eating [LOC], and binge eating) and depression. The study addresses 4 hypotheses. (1) The prospective relations between eating behaviors and depressive symptoms will be reciprocal, with each predicting the other over time. (2) These relations will be stronger for girls than for boys. (3) These relations will be stronger for adolescents with high (not low) body mass index (BMI). (4) LOC will show incremental predictive utility in relation to depressive symptoms over and above overeating. Evidence supported reciprocal relations between binge eating and depressive symptoms and between overeating and depressive symptoms, but not between LOC and depressive symptoms. Sex and BMI did not substantially moderate these relations. Taken separately, overeating but not LOC predicted depressive symptoms. Taken together, neither predictor was significant controlling for the other. Results raise questions about the importance of LOC alone in predicting depressive symptoms in adolescence.     

The effect of the order in which episodic autobiographical memories versus autobiographical knowledge are shared on feelings of closeness

Autobiographical memories (AMs) can be used to create and maintain closeness with others [Alea, N., &; Bluck, S. (2003). Why are you telling me that? A conceptual model of the social function of autobiographical memory. Memory, 11(2), 165–178]. However, the differential effects of memory specificity are not well established. Two studies with 148 participants tested whether the order in which autobiographical knowledge (AK) and specific episodic AM (EAM) are shared affects feelings of closeness. Participants read two memories hypothetically shared by each of four strangers. The strangers first shared either AK or an EAM, and then shared either AK or an EAM. Participants were randomly assigned to read either positive or negative AMs from the strangers. Findings suggest that people feel closer to those who share positive AMs in the same way they construct memories: starting with general and moving to specific.     

Characterizing the musical phenotype in individuals with Williams Syndrome.

Williams Syndrome (WS), a neurodevelopmental genetic disorder, is characterized by peaks and valleys in mental function: substantial impairments in cognitive domains such as reasoning, arithmetic ability, and spatial cognition, alongside relatively preserved skills in social domains, face processing, language, and music. We report the results of a comprehensive survey on musical behaviors and background administered to the largest sample of individuals with WS to date (n = 118, mean age = 20.4), and compare the results to those obtained from a control group of typically developing normal individuals (n = 118, mean age = 20.9) and two groups of individuals with other neurodevelopmental genetic disorders, Autism (n = 30, mean age = 18.2) and Down Syndrome (n = 40, mean age = 17.2). Individuals with WS were found to be rated higher in musical accomplishment, engagement, and interest than either of the comparison groups, and equivalent on most measures to the control group. Compared to all other groups including the controls, the WS individuals displayed greater emotional responses to music, manifested interest in music at an earlier age, and spent more hours per week listening to music. In addition, the effects of music listening (whether positive or negative) tended to last longer in the WS group. A factor analysis extracted seven principal components that characterize the musical phenotype in our sample, and discriminant function analysis of those factors was able to successfully predict group membership for the majority of cases. We discuss the neurobiological implications of these findings.     

Interaction of Recruiter and Applicant Gender in Resume Evaluation: A Field Study

In the present study, we examined the effect of recruiter and applicant gender on recruiters' evaluations of applicants' qualifications as reported on actual applicant resumes. Forty recruiters evaluated applicant resumes that were randomly allocated to them. In total, 388 recruiter evaluations of applicant resumes comprised the sample. Results indicate that recruiter and applicant gender interacted to predict recruiters' perceptions of applicants' qualifications. Male recruiters' perceptions of applicants' work experiences did not differ depending on applicant gender. However, female recruiters perceived male applicants' resumes to report more work experiences than resumes of female applicants. Furthermore, male recruiters perceived female applicants as having more extracurricular interests than male applicants. Female recruiters rated both male and female applicants as having about the same amount of extracurricular activity information on their resumes. Gender role theory provides a possible explanation for the study's findings.
