Differential Reinforcement of Alternative Behavior in Center-Based Classrooms: Evaluation of Pre-teaching the Alternative Behavior

This study investigated the effectiveness of a differential reinforcement of alternative behavior procedure in decreasing disruptive behavior while simultaneously increasing the appropriate behavior of four children of typical development between the ages of 4 and 6 in center-based classrooms. We began with brief functional analyses for each child. Then, differential reinforcement procedures, with and without pre-teaching the alternative behavior, were compared using an alternating treatments design. Results indicated that the differential reinforcement procedure with pre-teaching resulted in lower levels of problem behavior and greater levels of the alternative behavior compared to differential reinforcement alone. Results are discussed in terms of implications for applied practice and functional assessment and intervention research.     

The cognitive and neural basis of option generation and subsequent choice

Decision-making research has thoroughly investigated how people choose from a set of externally provided options. However, in ill-structured real-world environments, possible options for action are not defined by the situation but have to be generated by the agent. Here, we apply behavioral analysis (Study 1) and functional magnetic resonance imaging (Study 2) to investigate option generation and subsequent choice. For this purpose, we employ a new experimental task that requires participants to generate options for simple real-world scenarios and to subsequently decide among the generated options. Correlational analysis with a cognitive test battery suggests that retrieval of options from long-term memory is a relevant process during option generation. The results of the fMRI study demonstrate that option generation in simple real-world scenarios recruits the anterior prefrontal cortex. Furthermore, we show that choice behavior and its neural correlates differ between self-generated and externally provided options. Specifically, choice between self-generated options is associated with stronger recruitment of the dorsal anterior cingulate cortex. This impact of option generation on subsequent choice underlines the need for an expanded model of decision making to accommodate choice between self-generated options.     

Talking to Visitors about Conservation: Exploring Message Communication through Docent–Visitor Interactions at Zoos

ABSTRACT

Education personnel, both paid staff and volunteers, are often used at zoos and other museums as a channel to disseminate educational messages. This exploratory study examined the use of zoo docents to communicate key conservation messages from the zoo to visitors. The study was conducted in 2 phases using an emergent design with mixed methods. The findings suggest that visitors perceive docents to be an important source for conservation messages even though observed message communication through docent–visitor interactions was very limited. Docents view themselves as “facilitators for learning”, but their limited awareness of the institution's messages inhibits their ability to communicate these messages to visitors. Other factors that influence incidence of message communication are duration of the interaction, nature of the exhibit/region, and group composition. In this study, signage was found to be an effective channel for building cognitive awareness of messages among visitors.     

Business owner-managers' descriptions of entrepreneurship: A content analysis

Abstract

Entrepreneurship is one of the most researched topics in business research. Findings have been mixed regarding the traits of entrepreneurs, and interest has grown in examining the behavioral aspects and business operations elements necessary for effective entrepreneurship, branching out from the focus on personality traits that has dominated the literature. We explored the area of entrepreneurship with the goal of developing a useful framework for viewing this domain. Content analysis was used to build the framework from business owner-managers' observations of entrepreneurial effectiveness. The construct categories and the overall dimensions and their relationships to entrepreneurship are reported. The result is the beginning of a process to describe an entrepreneurship system. Suggestions for future research and the continuation of entrepreneurship model development are offered.     

Eucharistic sacrifice and patristic tradition in the theology of Martin Bucer 1534–1546

Abstract

As scholars continue to examine the variety and complexity of religious life in early modern England, we recognize that figures such as George Herbert resist our efforts to place them in convenient categories. However, we can account for this resistance by comparing Herbert's poetry to the Lutheran theologian Johann Gerhard's popular devotions of the same period. An intertextual study of Herbert's poems and Gerhard's devotional classic reveals their shared emphasis on baptism as an essential defining element of the Christian's life within the communion of saints. This emphasis synthesizes the tradition and sacramental piety of the old faith with the emphasis on the efficacy of the biblical word that marks the new faith of the Reformation and, at the same time, provides an irenic foundation for their interaction with the Church in early modern England.     

Evaluating Assistive Technology in the Education of Persons with Severe Disabilities

This commentary includes a brief discussion of issues raised by the articles and systematic review contained in this special issue addressing technology applications for persons with severe developmental disabilities. Topical areas include a discussion of; (1) a need to compare “high tech” with “low tech” applications, (2) procedural fidelity, (3) collateral effects associated with intervention, (4) the conditional use of newly established behavior, (5) response efficiency and contextual fit, and (6) treatment intensity.     

Coparenting interactions observed by the prenatal lausanne trilogue play: An Italian replication study

The infant–parent interaction is the focus of interest on early interactive relational models in the triadic perspective. This approach considers the mother–father–child interaction as the matrix of early competences, which start to develop well before delivery. This theoretical approach has generated an observation paradigm, the Lausanne Trilogue Play (LTP; E. Fivaz‐Depeursinge & A. Corboz‐Warnery, 1999). The aim of the study was to investigate (a) the psychometric characteristics of coding of the prenatal LTP procedure and their comparison with the Lausanne validation studies and (b) the characteristics of triadic interactions during pregnancy. Ninety‐eight nonreferred, primiparous families were recruited at childbirth courses. In addition to validated questionnaires, observational data were collected at the seventh month of pregnancy in the prenatal LTP. The collected data show good reliability of the LTP coding and a consistent factorial structure in line with the Lausanne validation studies (C. Carneiro, A. Corboz‐Warnery, & E. Fivaz‐Depeursinge, 2006; N. Favez et al., 2006). The Structure of the Play and the Intuitive Parenting Behaviors Scales seem the most representative dimensions in the prenatal period. Coparental abilities during pregnancy represent an interactive matrix for the construction of early family relations and may be considered as protective factors in the child's development of early triadic interactive abilities.     

Eye gaze metrics reflect a shared motor representation for action observation and movement imagery

Action observation (AO) and movement imagery (MI) have been reported to share similar neural networks. This study investigated the congruency between AO and MI using the eye gaze metrics, dwell time and fixation number. A simple reach-grasp-place arm movement was observed and, in a second condition, imagined where the movement was presented from the first person perspective (1PP) and the third person perspective (3PP). Dwell time and number of fixations were calculated for whole scene and regions of interest (ROIs). For whole scene, no significant differences were found in the number of fixations for condition (AO, MI) or perspective. Dwell time, however, was significantly longer in AO than MI. For ROIs, the number of fixations was significantly greater in 1PP than 3PP. The data provide support for congruence between motor simulation states but also indicate some functional differences.
