In the field of stimulus generalization, an old yet unresolved discussion pertains to what extent stimulus misidentifications contribute to the pattern of conditioned responding. In this article, we perform cluster analysis on six datasets (four published datasets and two unpublished datasets, included N = 950) to examine the relationship between…

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)…

Children with autism spectrum disorders (ASD) often emit errors during the establishment of conditional discriminations. These children may not respond to more traditional error-correction procedures, such as least-to-most prompting. In this study, we compared two other types of error-correction procedures, namely embedding an identity-matching…

Two experiments assessed the effects of extinguishing a conditioned cue on subsequent context conditioning. Each experiment used a different video-game method where sensors predicted attacking spaceships and participants responded to the sensor in a way that prepared them for the upcoming attack. In Experiment 1 extinction of a cue which signaled…

Generalization of fear can involve abnormal responding to cues that signal safety and is common in people diagnosed with post-traumatic stress disorder. Differential auditory fear conditioning can be used as a tool to measure changes in fear discrimination and generalization. Most prior work in this area has focused on elevated amygdala activity…
