Structural racism is rooted in American social systems that were supposedly designed to promote citizens' right to life, liberty, and the pursuit of happiness. Social systems like policing, for example, are built on a foundation of discriminatory practices designed to disenfranchise Black, Indigenous, and people of color (BIPOC). One of the most recent visible examples of racially biased policing is the excessive use of force by officers toward BIPOC.

The current study evaluated whether a computer-based training program could improve observers' accuracy in scoring discrete instances of problem behavior at 5x normal speed using a multiple-baseline design across subjects. During pretraining and posttraining, observers attempted to score multiple examples of problem behavior at 5.0x without feedback.

Parents play an important role in the treatment of their children's symptoms of autism spectrum disorder (ASD); thus, developing effective, efficient, socially acceptable, and accessible procedures for training parents to implement applied-behavior-analysis (ABA) interventions is critically important. One potential approach involves delivering training via a virtual private network (VPN) over the internet (Fisher et al., 2014).

Children with autism spectrum disorder (ASD) often display impaired listener skills, and few studies have evaluated procedures for establishing initial auditory-visual conditional discrimination skills. We developed and evaluated a treatment package for training initial auditory-visual conditional discriminations based on the extant research on training such discriminations in children with ASD with at least some preexisting skills in this area. The treatment package included (a) conditional-only training, (b) prompting the participant to echo the sample stimulus as a differential observing response, (c) prompting correct selection responses using an identity-match prompt, (d) using progressively delayed prompts, and (e) repeating trials until the participant emitted an independent correct response.

Technological advances have allowed professionals to obtain extended recordings of caregiver-client interactions in natural settings, but scoring recorded video at normal speed to identify instances of low-rate problem behavior is impractical in terms of scoring time. Fast forwarding is a continuous measurement system in which all seconds of an observation are viewed at a speed faster than normal. In Study 1, we evaluated whether three groups of five observers could discriminate problem behavior at three fast-forwarding speeds across 10-min observations.

We taught manual signs to typically developing infants using a reversal design and caregiver-nominated stimuli. We delivered the stimuli on a time-based schedule during baseline. During the intervention, we used progressive prompting and reinforcement, described by Thompson et al.
