Eye movements of monkey observers viewing vocalizing conspecifics

Primates, including humans, communicate using facial expressions, vocalizations and often a combination of the two modalities. For humans, such bimodal integration is best exemplified by speech-reading - humans readily use facial cues to enhance speech comprehension, particularly in noisy environments. Studies of the eye movement patterns of human speech-readers have revealed, unexpectedly, that they predominantly fixate on the eye region of the face as opposed to the mouth. Here, we tested the evolutionary basis for such a behavioral strategy by examining the eye movements of rhesus monkeys observers as they viewed vocalizing conspecifics. Under a variety of listening conditions, we found that rhesus monkeys predominantly focused on the eye region versus the mouth and that fixations on the mouth were tightly correlated with the onset of mouth movements. These eye movement patterns of rhesus monkeys are strikingly similar to those reported for humans observing the visual components of speech. The data therefore suggest that the sensorimotor strategies underlying bimodal speech perception may have a homologous counterpart in a closely related primate ancestor.     

Consultation in family therapy

Abstract

This paper addresses the issue of the use of consultants by experienced family therapists. The authors discuss the need for consultation under different circumstances and review a number of models currently being utilized. Emphasis is placed on preparing the clients for the consultation, providing background information to and preparing with the consultant for the session(s), and transferring “power” to the consultant and back again to the primary therapist.     

Media Exposure and Attitudes Toward Drug Addiction Spending, 1975–2004

In this article we examine the relationships between media exposure (television and newspaper) and drug addiction spending attitudes. Theory and research suggest the critical role of media for shaping views and influencing public opinion. However, no studies have considered media's impact for individual-level drug-related attitudes. We examine this using General Social Survey and other data from 1975 to 2004. Results from logistic regression analyses indicate that greater frequency of television viewing and of newspaper reading are associated with higher likelihoods of saying too little money is spent to address addiction. These findings are robust even when accounting for other factors.     

Smoking cross-culturally: Risk perceptions among young adults in Denmark and the United States

Research examining smokers’ understanding of their smoking risk reveals that smokers acknowledge some risk but often deny or minimize personal risk. We examined risk perceptions of lung cancer among smokers and non-smokers in a smoking-lenient (Denmark) and a smoking-prohibitive (the United States) culture. Participants were 275 Danish students attending trade schools (mean age 22.6 years) and 297 US students attending community colleges in Florida (mean age 23.6 years). Results revealed cross-cultural differences suggesting that Danish smokers showed greater risk minimization than US smokers. In addition, in both countries the risk of a typical smoker was rated as lower by smokers than non-smokers, and smokers rated their personal risk as lower than they rated the risk of the typical smoker. Cross-cultural differences in moralization of smoking might be one explanation for these findings.     

The Effect of Interactivity on Learning Physical Actions in Virtual Reality

Virtual reality (VR) offers new possibilities for learning, specifically for training individuals to perform physical movements such as physical therapy and exercise. The current article examines two aspects of VR that uniquely contribute to media interactivity: the ability to capture and review physical behavior and the ability to see one's avatar rendered in real time from third person points of view. In two studies, we utilized a state-of-the-art, image-based tele-immersive system, capable of tracking and rendering many degrees of freedom of human motion in real time. In Experiment 1, participants learned better in VR than in a video learning condition according to self-report measures, and the cause of the advantage was seeing one's avatar stereoscopically in the third person. In Experiment 2, we added a virtual mirror in the learning environment to further leverage the ability to see oneself from novel angles in real time. Participants learned better in VR than in video according to objective performance measures. Implications for learning via interactive digital media are discussed.     

Perception of threat and safety at work among employees in the Norwegian ministries after the 2011 Oslo bombing

Background and objectives: Terrorism can heighten fears and undermine the feeling of safety. Little is known, however, about the factors that influence threat and safety perception after terrorism. The aim of the present study was to explore how proximity to terror and posttraumatic stress reactions are associated with perceived threat and safety after a workplace terrorist attack. Design and methods: A cross-sectional questionnaire survey was administered to employees in 14 of 17 Norwegian ministries 9–10 months after the 2011 bombing of the government headquarters in Oslo (n = 3520). Results: About 198 of 1881 employees completing the survey were at work when the bomb exploded. Regression analysis showed that this high-exposed group had elevated perceived threat (β = 0.36; 95% CI = 0.19 to 0.53) and reduced perceived safety (β = ?0.42; 95% CI = ?0.62 to ?0.23) compared to a reference group of employees not at work. After adjusting for posttraumatic stress reactions, however, proximity to the explosion no longer mattered, whereas posttraumatic stress was associated with both high perceived threat (β = 0.55; 95% CI = 0.48 to 0.63) and low perceived safety (β = ?0.71; 95% CI, ?0.80 to ?0.63). Conclusion: Terror-exposed employees feel more threatened and less safe after a workplace terrorist attack, and this is closely linked to elevated levels of posttraumatic stress reactions.     

Silence is golden? Characteristics and experiences of self-reported whistleblowers

This study investigates the characteristics of whistleblowers, the prevalence and nature of whistleblowing, and the occurrence of retaliation after whistleblowing using a randomly selected and representative sample of Norwegian employees. The results showed that 12 per cent self-reported as whistleblowers according to an operational definition. Being a leader, or a union or personnel safety representative was significantly related to whistleblowing. The most frequently reported wrongdoing was harassment conducted by a single colleague. Wrongdoer(s) received mixed responses, from no reaction to reprimand. Even though most whistleblowers were not sanctioned, they reported less job satisfaction and more workplace bullying than did nonwhistleblowers. Only a few were rewarded. For the most part, wrongdoing was stopped or reduced. However, whistleblowing was only partially effective, because whistleblowers reported lack of feedback about the result of their report. Results also showed that the status of the wrongdoer was related to the reaction he or she received afterwards, as were the type of wrongdoing and the effect on the wrongdoing, and the type of wrongdoing and the effect on the wrongdoer(s). Potential explanations for the results, such as the type of sample and power distance, are discussed. Practical implications of the study are also addressed, such as the importance of providing feedback to whistleblowers.
