Behavior analysts collaborating within interdisciplinary teams are likely to find themselves at difficult crossroads. Some of these crossroads include implementing alternative treatments, defining and determining risk and harm, and evaluating research and interventions. The purpose of this paper is to highlight some of these crossroads and provide…

Background: Africa is increasingly becoming an important region for health research, mainly due to its heavy burden of disease, socioeconomic challenges, and inadequate health facilities. Regulatory capacities, in terms of ethical review processes, are also generally weak. The ethical assessment of social and behavioral research is relatively…

The value of an outcome is affected both by the delay until its receipt (delay discounting) and by the likelihood of its receipt (probability discounting). Despite being well-described by the same hyperboloid function, delay and probability discounting involve fundamentally different processes, as revealed, for example, by the differential effects…

"The Belmont Report" was written in 1979 to address the abuse of human participants in biomedical research. In the report, three ethical principles were described: (1) "beneficence," which describes an act of charity or kindness that maximizes possible benefits while minimizing possible harms; (2) "justice," described…

Background: Cigarette and alcohol use are common among youth. We examined sources of cigarettes and alcohol among youth who were current cigarette and alcohol users. Methods: We analyzed nationally representative data from the 2009 and 2011 national Youth Risk Behavior Surveys--biennial, school-based surveys of high school students in the United…

Pigeons were given repeated choices between variable and fixed numbers of token reinforcers (stimulus lamps arrayed above the response keys), with each earned token exchangeable for food. The number of tokens provided by the fixed-amount option remained constant within blocks of sessions, but varied parametrically across phases, assuming values of…

In the behavioral sciences, a popular approach to describe and predict behavior is cognitive modeling with adjustable parameters (i.e., which can be fitted to data). Modeling with adjustable parameters allows, among other things, measuring differences between people. At the same time, parameter estimation also bears the risk of overfitting. Are…

Presents a short biography of one of the winners of the American Psychological Association's Award for Distinguished Scientific Early Career Contributions to Psychology. The 2012 winner is Angela J. Grippo for her creative contributions in investigating the association between depression and cardiovascular disease in preclinical animal models.…

Background: Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) share about 50-72% of their genetic factors, which is the most likely explanation for their frequent co-occurrence within the same patient or family. An additional or alternative explanation for the co-occurrence may be (cross-)assortative mating, e.g.,…

For the first time in twenty years the U.S. Department of Health and Human Services (DHHS, 2009) is considering changes to federal regulations governing research. The Common Rule provides the basis for government regulations and Institutional Review Boards (IRB). Proposed changes will have a significant impact on Institutional Review Board…

Although research indicates that adoption of flood preparations among Europeans is low, only a few studies have attempted to explain citizens' preparedness behavior. This article applies the Protective Action Decision Model (PADM) to explain flood preparedness intentions in the Netherlands. Survey data ("N" = 1,115) showed that…

This article reports on a recent research project undertaken in the UK that investigated young adults' perception of potentially risky behaviour online. The research was undertaken through the use of an online survey associated with the UK teen soap opera "Being Victor". The findings of the project suggest that this sample of British…

On July 26, 2011, the U.S. Department of Health and Human Services issued an advance notice of proposed rulemaking (ANPRM) with the purpose of soliciting comments on how current regulations for protecting research participants could be modernized and revised. The rationale for revising the regulations was as follows: this ANPRM seeks comment on…

Experimental research in business and economics has exploded in recent years in both laboratory and field settings. The generality of findings from field experiments is limited by the specificity of the experimental environment. Laboratory studies, on the other hand, are criticized for being devoid of the contextual cues that may indicate to…

In this article, we directly question the common practice in growth mixture model (GMM) applications that exclusively rely on the fitting model without covariates for GMM class enumeration. We provide theoretical and simulation evidence to demonstrate that exclusion of covariates from GMM class enumeration could be problematic in many cases. Based…
