The Gambler’s Fallacy Is Associated with Weak Affective Decision Making but Strong Cognitive Ability

The Gambler’s Fallacy Is Associated with Weak Affective Decision Making but Strong Cognitive Ability | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it

Humans demonstrate an inherent bias towards making maladaptive decisions, as shown by a phenomenon known as the gambler’s fallacy (GF). The GF has been traditionally considered as a heuristic bias supported by the fast and automatic intuition system, which can be overcome by the reasoning system. The present study examined an intriguing hypothesis, based on emerging evidence from neuroscience research, that the GF might be attributed to a weak affective but strong cognitive decision making mechanism. With data from a large sample of college students, we found that individuals’ use of the GF strategy was positively correlated with their general intelligence and executive function, such as working memory and conflict resolution, but negatively correlated with their affective decision making capacities, as measured by the Iowa Gambling Task. Our result provides a novel insight into the mechanisms underlying the GF, which highlights the significant role of affective mechanisms in adaptive decision-making.

New theory linking brain activity to brain shape could throw light on human consciousness | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
Scientists have shown that complex human brain activity is governed by the same simple universal rule of nature that can explain other phenomena such as the beautiful sound of a finely crafted violin or the spots on a leopard. They have identified a link between the distinctive patterns of brain function that occur at rest and the physical structure of people's brains.

Stress inhibits spatial perception

Stress inhibits spatial perception | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
Neuroscientists have investigated the effects of stress on the perception of scenes and faces. In a behavioral study, they compared the results of stressed participants with those of an unstressed control group. They were able to show that stress inhibits the perception of complex spatial information. The reason for this lies in the processing of this information in the hippocampus, an area in the temporal lobe of the brain, which is influenced by the stress hormone cortisol.
