How environmental movement constraints shape the neural code for space

Study of the neural code for space in rodents has many insights to offer for how mammals, including humans, construct a mental representation of space. This code is centered on the hippocampal place cells, which are active in particular places in the environment. Place cells are informed by numerous other spatial cell types including grid cells, which provide a signal for distance and direction and are thought to help anchor the place cell signal. These neurons combine self-motion and environmental information to create and update their map-like representation. Study of their activity patterns in complex environments of varying structure has revealed that this "cognitive map" of space is not a fixed and rigid entity that permeates space, but rather is variably affected by the movement constraints of the environment. These findings are pointing toward a more flexible spatial code in which the map is adapted to the movement possibilities of the space. An as-yet-unanswered question is whether these different forms of representation have functional consequences, as suggested by an enactivist view of spatial cognition.

     

Youth mentoring: The American Dream comes to the UK?

This paper examines the ways in which the North American experience has influenced youth mentoring programmes in the UK and focuses on the theoretical assumptions about young people which have underpinned mentoring interventions. A more critical approach to this North American 'legacy' is required if the value of this form of intervention is to be accurately assessed. The paper argues that an over-reliance by mentoring interventions on developmental paradigms has curtailed their capacity to take account of the wider social context in which young people are making their transitions to adulthood. It is suggested that alternative theoretical frameworks which address the complexity and multiplicity of youth transitions hold more promise for understanding and theorising the role of mentoring in the UK setting. A recent Scottish study of informal mentoring processes attempted to open up these theoretical possibilities by using a framework which recognised young people as active participants and agents. This study revealed that a range of models of mentoring may be in place within informal mentoring relationships. The paper argues that findings from this study demonstrated a need for a more critical approach to the 'classic notion' of mentoring as exclusively a one to one relationship between an adult and a young person. Since mentoring is now a highly popular form of intervention with 'socially excluded' young people these questions about the theoretical base for the concept require urgent attention.     

An assessment of social validity trends in applied behavior analysis

Research articles published during the first 31 years of Journal of Applied Behavior Analysis were assessed for reports of social validity measures. Two measures of social validity (treatment outcome and treatment acceptability) were assessed for each article. In addition, articles were assessed for the incorporation of analog versus naturalistic settings. Overall, treatment outcome and acceptability measures were reported in less than 13% of articles. In addition, studies conducted in naturalistic settings were more likely to report social validity measures than studies conducted in analog settings. Possible reasons for the deficit in the reporting of social validity measures and potential outcomes of this deficit are discussed. Copyright © 1999 John Wiley & Sons, Ltd.     

Behavioral skills training to increase interview skills of adolescent males in a juvenile residential treatment facility

Some studies suggest that acquiring employment following release from prison may reduce recidivism; however, few studies have evaluated procedures for teaching job-related skills to adolescents in residential detention facilities. Stocco et al. (2017) used behavioral skills training (BST) to improve interview skills of college students. The current study used a nonconcurrent multiple baseline design across participants to evaluate the extent to which BST improved interview skills for 7 adolescents who had been adjudicated for sexual offenses. Results show that BST increased appropriate responses to interview questions for 4 students and BST plus modifications (i.e., stimulus and response prompts) increased correct responding to questions for the other 3. In addition, BST increased appropriate questions, correct posture, and smiling, and decreased fidgeting for all 7 students. We briefly discuss the social implications of teaching interview skills to adjudicated adolescents, as well as the limitations of the findings.
