We consider estimating the effect of a treatment on a given outcome measured on subjects tested both before and after treatment assignment in observational studies. A vast literature compares the competing approaches of modelling the post-test score conditionally on the pre-test score versus modelling the difference, namely, the gain score. Our…

Marketing emerges as the foundational force in societies of control, adept at shaping individual desires and cultivating them into consumerism.

The American Speech-Language-Hearing Association (n.d.) suggests that acquisition and use of augmentative and alternative communication (AAC) is dynamic and that learning multiple modalities may be beneficial particularly for those individuals with severe disabilities.

We argue that current policy reifies skills as market commodities and alienates them from the minds, bodies, and hands of those who exercise them and the…

Using spatial mapping processes to discriminate between threat and safety is crucial for survival. Little is known why some fail to discriminate during contextual conditioning. We used a virtual reality (VR) contextual conditioning paradigm to elucidate the effects of state and trait anxiety on contextual threat learning. Participants (n = 70)…
