The Power of Causal Attributions: Genetic Essentialist Biases and Health. Great advancements in the science of genetics are accompanied by increased public propensity to attribute causality to the genes for diverse outcomes such as abilities, social group differences, attitudes, and diseases. These genetic attributions activate cognitive biases termed Genetic Essentialist Biases, which have been shown to instigate a variety of deleterious outcomes.

Great advancements in the science of genetics are accompanied by increased public propensity to attribute causality to the genes for diverse outcomes such as abilities, social group differences, attitudes, and diseases. These genetic attributions activate cognitive biases termed Genetic Essentialist Biases, which have been shown to instigate a variety of deleterious outcomes. The project will evaluate hypothesized detrimental effects of genetic attributions on actual health behaviours, endorsement of health policies, and disease related stigma. Furthermore, it will test interventions designed to reduce the negative effects of such attributions on attitudes, beliefs, intentions, and behaviours related to a common disease. Read moreRead less
Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as pred ....Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as predator cues, enhance avoidance behaviour. This project will uncover the neural circuitry and endocrine mechanisms through which hunger influences hypothalamic threat-detecting circuits that suppress food intake. These studies provide a new hypothalamic model to understand risk/reward decision in the brain.Read moreRead less
