Do zoo visitors induce attentional bias effects in primates completing cognitive tasks?

Animal Cognition - While previous research has focused on the impact of visitors on zoo-housed animals’ behavior, here, we evaluated the impact of visitors on the performance of four...     

The relationship between career decision status and important work outcomes

This paper describes a longitudinal study exploring the relationship between career decision status and work outcomes (i.e. job satisfaction, organizational commitment and performance) in a group of newly appointed graduates. Graduates employed into similar roles in a large Multinational Consultancy were tracked over 12 months at three time intervals: on appointment; 6 months after appointment and 12 months after appointment. It was concluded that job satisfaction promotes career comfort, decidedness predicts organizational commitment and this relationship is moderated by met expectations, and that neither being decided or comfortable predicts performance. Some evidence was found to suggest that those employees claiming high self-clarity (that is knowledge of their abilities, skills, and personality) were rated as higher performers. It was concluded that career decidedness is still relevant to a contemporary work environment, but that comfort with career decisions and knowledge of self (i.e. self-clarity) has the potential for far greater impact.     

‘You Are What You Read:’ Is selective exposure a way people tell us who they are?

Selective exposure is the tendency to gather viewpoint-congenial versus viewpoint-uncongenial information. Extant models of selective exposure suggest this tendency occurs because people anticipate reading congenial (vs. uncongenial) information will cause more favourable intrapersonal consequences. However, these models ignore the notion that people's information choices are, in part, symbolic gestures designed to convey identity-relevant beliefs to an audience through information display. Drawing from perspectives that emphasize human consumption as symbolic and a way to signal one's identity, we suggest that selective exposure pertains not only to information processing but also to conveying identity through information display. Experiment 1 showed that people characterize information display as a way to communicate their views to an audience. Experiments 2–4 showed that people are averse to displaying uncongenial versus congenial information (without processing the information), anticipate feeling more uncomfortable and more inauthentic merely displaying (without processing) uncongenial versus congenial information, and that people's intentions to engage in selective exposure in daily life are a function of their belief that selective-exposure displays convey their identity. None of these studies or findings can be generated from extant selective-exposure theories. Thus, selective-exposure theories are likely incomplete because they ignore people's beliefs and goals regarding information display.     

Recruitment modeling applied to longitudinal studies of group differences in intelligence

In longitudinal studies data is collected in a series of waves. Each wave after the first suffers from attrition. Therefore it can be difficult to discriminate between changes in sample parameters due to a longitudinal process (e.g. ageing) and changes due to attrition. The problem is particularly vexing if one of the purposes is to compare differences between two or more groups over time, because there may be differential attrition across groups. We refer to this as a recruitment problem, because the sample studied in any wave after the first can be thought of as having been recruited from a preceding wave. We present a mathematical model of the recruitment process. We then apply it to two large longitudinal studies, the British Cohort Survey 1970 and the National Child Development Study (1958), to demonstrate how we can identify effects expected from recruitment alone. As an illustration we show that differential recruitment would predict increasing differences between estimates of men's and women's intelligence as the studied sample ages.     

Hey stud: Race, sex, and sports

This article is an examination of how the intersection of sport and race plays out in the sexualization of the sporting role of African American male athletes. Further, the article is an examination of the multiple roles the media, sport, and race play as these impact the public persona of African American male athletes in high-profile sports. The article concludes with a number of recommendations for ending the negative images of African American male athletes. To the white public, we are athletes, rappers, preachers, singers—and precious little else. We are also robberts, rapists, mentally deficient and sexually well endowed. —Ellis Cose, The Envy of the World: On Being a Black Man in America (2002; New York: Washington Square Press, 3–4) First of all, let me say good after ... good late afternoon. Because of the HIV virus I have attained, I will have to announce my retirement from the Lakers today. I just want to make clear, first of all, that I do not have the AIDS disease, because I know a lot of you want to know that, but the HIV virus. My wife is fine, she’s negative, so no problem with her. I plan on going on, living for a long time, bugging you guys like I always have. So you’ll see me around. I plan on being with the Lakers and the league—hopefully [Commissioner] David [Stern] will have me for a while—and going on with my life. I guess now I get to enjoy some of the other sides of living—that [were missed] because of the season and the long practices and so on. I just want to say that I’m going to miss playing. And I will now become a spokesman for the HIV virus because I want people, young people, to realize they can practice safe sex. And, you know, sometimes you’re a little naive about it and you think it could never happen to you. You only thought it could happen to, you know, other people and so on and on. And it has happened. —Magic Johnson—Press Conference at L.A. Lakers Compound Washington Post, November 9, 1991     

Observational learning of tool use in children: Investigating cultural spread through diffusion chains and learning mechanisms through ghost displays

In the first of two experiments, we demonstrate the spread of a novel form of tool use across 20 “cultural generations” of child-to-child transmission. An experimentally seeded technique spread with 100% fidelity along twice as many “generations” as has been investigated in recent exploratory “diffusion” experiments of this type. This contrasted with only a single child discovering the technique spontaneously in a comparable group tested individually without any model. This study accordingly documents children’s social learning of tool use on a new, population-level scale that characterizes real-world cultural phenomena. In a second experiment, underlying social learning processes were investigated with a focus on the contrast between imitation (defined as copying actions) and emulation (defined as learning from the results of actions only). In two different “ghost” conditions, children were presented with the task used in the first experiment but now operated without sight of an agent performing the task, thereby presenting only the information used in emulation. Children in ghost conditions were less successful than those who had watched a model in action and showed variable matching to what they had seen. These findings suggest the importance of observational learning of complex tool use through imitation rather than only through emulation. Results of the two experiments are compared with those of similar experiments conducted previously with chimpanzees and are discussed in relation to the wider perspective of human culture and the influence of task complexity on social learning.
