The present study replicated and extended previous research by exploring the extent to which rules altered participants' engagement in risky betting in an electronic blackjack game. A multiple-baseline across-participants design with predetermined phase changes was used to assess 4 recreational gamblers' betting patterns in blackjack across 3…

Common response-time-based approaches for non-effortful response behavior (NRB) in educational achievement tests filter responses that are associated with response times below some threshold. These approaches are, however, limited in that they require a binary decision on whether a response is classified as stemming from NRB; thus ignoring…

Propensity score weighting often is used to correct for attrition biases in panel surveys. While methodological literature exists on the logic of propensity score weighting and its practical applications, an in-depth discussion is lacking on the effects of using this weighting to correct for attrition biases in attitudinal, behavioral, and…

Wong et al. (2014) conducted a comprehensive review of the literature published between 1990 and 2011 to identify practices for children, adolescences, and young adults diagnosed with autism spectrum disorders (ASD) that had sufficient empirical support to be considered evidence-based. Behavior momentum interventions (BMI), or high-probability…

Pseudocontingencies are inferences about correlations in the environment that are formed on the basis of statistical regularities like skewed base rates or varying base rates across environmental contexts. Previous research has demonstrated that pseudocontingencies provide a pervasive mechanism of inductive inference in numerous social judgment…

Learning to choose adaptively when faced with uncertain and variable outcomes is a central challenge for decision makers. This study examines repeated choice in dynamic probability learning tasks in which outcome probabilities changed either as a function of the choices participants made or independently of those choices. This presence/absence of…

An experiential education program was designed to target risk perceptions and preventative measures that make people feel comfortable in human-coyote interactions. The research was conducted in a Canadian national park where a coyote caused a human fatality in 2009. Based on previous research, we explored the effects of an experience-based coyote…

Adaptive decision making in probabilistic environments requires individuals to use probabilities as weights in predecisional information searches and/or when making subsequent choices. Within a child-friendly computerized environment (Mousekids), we tracked 205 children's (105 children 5-6 years of age and 100 children 9-10 years of age) and 103…

Background: Despite the critical role of educators as gatekeepers for school mental health services, they receive limited training to support student mental health. We report findings from a trial of an online mental health role-play simulation for elementary school teachers on changes in attitudes and self-reported helping behaviors for students…

We quantified the effect of first experience on behavior in operant learning and studied its underlying computational principles. To that goal, we analyzed more than 200,000 choices in a repeated-choice experiment. We found that the outcome of the first experience has a substantial and lasting effect on participants' subsequent behavior, which we…

The incidence of work accidents in the construction industry particularly in Indonesia and generally internationally shows an increasingly worrying trend given that either quantitatively or qualitatively the number of work accidents is very large compared to that of other industrial sectors. The main causing factors are mostly due to the workers'…

Pigeons responded in a perceptual categorization task with six different stimuli (shades of gray), three of which were to be classified as "light" or "dark", respectively. Reinforcement probability for correct responses was varied from 0.2 to 0.6 across blocks of sessions and was unequal for correct light and dark responses. Introduction of a new…

The joint development of trajectories of bullying perpetration and peer victimization from Grade 5 to Grade 8 and concurrent and predictive associations with parent- and child-reported symptoms of psychopathology (anxiety, depression, attention-deficit/hyperactivity disorder, and somatization) were examined in a large sample (N = 695) of Canadian…

Pigeons show a preference for an alternative that provides them with discriminative stimuli (sometimes a stimulus that predicts reinforcement and at other times a stimulus that predicts the absence of reinforcement) over an alternative that provides them with nondiscriminative stimuli, even if the nondiscriminative stimulus alternative is…

Participants completed blocks of trials under simple (i.e., work-alone), competitive, and self-competitive fixed-interval 20-s schedules of reinforcement. In general, response rates were highest during competition and lowest while working alone. In addition, whereas participants emitted responses at a constant rate while working alone, competitive…
