Inoculation theory offers a framework for protecting individuals against challenges to an existing attitude, belief, or state. Despite the prevalence and damaging effects of public speaking anxiety, inoculation strategies have yet to be used to help individuals remain calm before and during public speaking. We aimed to test the effectiveness of an inoculation message for reducing the onset of public speaking anxiety, and helping presenters interpret their speech-related anxiety more positively. Participants (Mage = 20.14, SD = 2.72) received either an inoculation (n = 102) or control (n = 128) message prior to engaging a public …

It has long been thought that the eyes index the inner workings of the mind. Consistent with this intuition, empirical research has demonstrated that pupils dilate as a consequence of attentional effort. Recently, Smallwood et al. (2011) demonstrated that pupil dilations not only provide an index of overall attentional effort, but are time-locked to stimulus changes during attention (but not during mind-wandering). This finding suggests that pupil dilations afford a dynamic readout of conscious information processing. However, because stimulus onsets in their study involved shifts in luminance as well as information, they could not determine whether this coupling of stimulus …

Preference-Based Serial Decision Dynamics: Your First Sushi Reveals Your Eating Order At The Sushi Table, Jaeseung Jeong, Youngmin Oh, Miriam Chun, Jerald D. Kralik

In everyday life, we regularly choose among multiple items serially such as playing music in a playlist or determining priorities in a to-do list. However, our behavioral strategy to determine the order of choice is poorly understood. Here we defined ‘the sushi problem’ as how we serially choose multiple items of different degrees of preference when multiple sequences are possible, and no particular order is necessarily better than another, given that all items will eventually be chosen. In the current study, participants selected seven sushi pieces sequentially at the lunch table, and we examined the relationship between eating order and …

Children with malformations of cortical development (MCD) frequently have associated cognitive impairments which reduce quality of life. We hypothesized that cognitive deficits associated with MCD can be improved with environmental manipulation or additional training. The E17 methylazoxymethanol acetate (MAM) exposure model bears many anatomical hallmarks seen in human MCDs as well as similar behavioral and cognitive deficits. We divided control and MAM exposed Sprague-Dawley rats into enriched and non-enriched groups and tested performance in the Morris water maze. Another group similarly divided underwent sociability testing and also underwent Magnetic Resonance Imaging (MRI) scans pre and post enrichment. A third group …
