We then examine studies involving critical samples with impaired self-regulation.

One effective strategy to reduce this intention–behavior gap is the formation of implementation intentions that specify when, where, and how to act on a given goal in an if-then format (“If I encounter situation Y, then I will initiate action Z! It has been proposed that implementation intentions render the mental representation of the situation highly accessible and establish a strong associative link between the mental representations of the situation and the action.

In support of the assumed processes, implementation intentions increased goal attainment in studies on cognitive processes and in critical samples, modulated brain waves related to perceptual and decision processes, and generated less activity in brain areas associated with effortful action control.

In our discussion, we reflect on the status quo of physiological research on implementation intentions, methodological and conceptual issues, related research, and propose future directions. doi: 10.1002/acp.775 Cross Ref Full Text | Google Scholar Mc Farland, C.

Isto é, independentemente do prazer que sentimos ao saborear uma sobremesa, nosso organismo sinaliza a necessidade de comer açúcar. Já se sabia da existência das duas diferentes formas, hedônica e nutricional, de estímulo do consumo dos alimentos, mas o estudo descreve sua ocorrência em locais distintos do estriado, uma região do sistema nervoso que é fundamental para o processamento de recompensas.

A porção inferior do sistema, conhecida como estriado ventral, possibilita a percepção do prazer proporcionada pelo sabor doce, enquanto a superior, chamada de estriado dorsal, é responsável por reconhecer o valor calórico e nutricional dos alimentos.
