Examining the impact of traffic environment and executive functioning on children's pedestrian behaviors

The process of integrating visual information and planning a safe crossing is cognitively demanding for many young children. We assessed relations between traffic characteristics, aspects of children's executive functioning (EF), and pedestrian behavior, with the aim being to determine whether well-developed EF would predict safer pedestrian behaviors beyond the contributions of child demographic and traffic environment factors. Using the pretend road method, we studied a sample of 83 children aged 6-9 in a series of 5 crossing trials beside a real road in response to actual traffic conditions. Traffic characteristics and pedestrian behaviors were observed and measured across crossing trials. Both traffic characteristics and EF, most notably cognitive efficiency, were strongly related to children's pedestrian crossing behaviors. Traffic characteristics were also found to interact with children's ability to monitor their crossing performance. Examining developmental influences in pedestrian injury etiology broadens researchers' knowledge of and ability to prevent injuries by moving beyond describing what happens to children and examining why pedestrian injuries occur.     

Training Insightful Problem Solving: Effects of Realistic and Puzzle-Like Contexts

Attempts to train people to be more insightful problem solvers have met with mixed success. This article reports the results of a controlled investigation on the effects of training with 40 participants who were equally divided into training and control conditions. Training consisted of 10 minutes of instruction and practice at avoiding or responding to the impasses that arise in insight problems. All participants were then tested on three types of problem, half of them receiving the problems in an artificial puzzle-like format, and half received the same problems set in a more realistic context. The results extended previous findings by indicating an impact of training on a range of puzzle-like problems, but not on the more realistic versions of problems, where performance with or without training was as good as that of puzzle-like problems after training. Future research will investigate whether the training procedure can be adapted to be effective with real-like problems and will examine the implications for training in the field.     

The specificity of expertise: For whom is the clave pattern the “key” to salsa music?

Each Latin salsa music style is associated with a characteristic clave pattern that constitutes an essential structure for performers. In this article we asked what types of expertise are needed to detect the correct salsa–clave pairing. Using two clave patterns (the 3–2 and 2–3 son clave) and three manipulated alternatives, we asked listeners to choose the correct clave pattern for a variety of bomba, calypso, mambo and merengue excerpts. The results of Studies 1 and 2 show that listeners unfamiliar with salsa were unable to detect the correct salsa–clave pairing. Listeners who had some music training or were familiar with salsa detected the need for syncopation but not the specific pairing. Only musicians well-acquainted with salsa correctly detected the salsa–clave pairing. Studies 3 and 4 showed that incorrect choices were not due to an inability to distinguish between the alternatives: both adults and five-year-olds could easily tell apart the various patterns we used. We conclude that the distinction between the 2–3 and 3–2 claves is not inherent in the music itself, but rather is a convention to be learned through exposure and training. We discuss the results using an analogy to language learning.     

The Changing Environment of Selling and Sales Management

New developments and trends in selling and sales management are creating demands and opportunities that require adaptation and new approaches on the part of both sales organizations and academic researchers. This paper summarizes critical dimensions of change in the environment that affect the practice of selling and sales management and introduces the papers that follow in this Anniversary Special Issue of JPSSM.     

A Review of Jesus: A Psychological Biography

Capps's book uses historical, sociological, and psychological methods to probe the personal identity and self-understanding of Jesus. This reviewer suggests that historical, sociological, and psychological methods are modes of discourse that are modern forms of myth. Myth is understood as any narrative form that is used, and/or taken for granted, as a way of self-understanding and understanding the world. These disciplines are useful critical tools with which to explore the text and its world, but they do not guarantee knowledge about the past. As modern modes of discourse they create narratives (i.e., myths) about the past, that for us are preferred epistemological pathways. Jesus Christ is the ultimate model of the God-person relationship in the Christian west. Therefore, any serious attempt to render a realistic portrait of Jesus using contemporary modes of describing reality has the possibility of effecting a profound transformation of the images of God and Jesus. This then can transform our own relationship with God. The value of Capps's book is not in any knowledge it might give us about Jesus, but in the transformation it can effect within the reader, and the author, of central religious images. Psychoanalytic and developmental theories are limited in their explanatory effectiveness because they are materialistic and personalistic (reductive). The analytical psychology of Carl Jung and the archetypal psychology of James Hillman are proposed in order to add a transpersonal dimension to Capps's approach to the personality of Jesus.
