Emotion-based decision making (EBDM) is the capacity to make decisions based on prior emotional consequences of actions. Several neuropsychological tasks, using different gambling paradigms and with different levels of complexity, have been designed to assess EBDM. The Bangor Gambling Task (BGT) was created as a brief and simple card gambling-task to assess EBDM.

Background: Children's preferences for cariogenic foods and/or drinks has been proven to be associated with exposure to advertisements. This study aimed to assess and compare the proportion of cariogenic food and /or drink advertisements aired on three metropolitan Sydney commercial television channels at different broadcast times during school term and school holidays.

Methods: Three Sydney free-to-air television channels (Channels Seven, Nine, and Ten) were recorded between June 2016 and January 2017.

Interest in the cognitive and/or emotional basis of complex decision-making, and the related phenomenon of emotion-based learning, has been heavily influenced by the Iowa Gambling Task. A number of psychological variables have been investigated as potentially important in understanding emotion-based learning. This paper reviews the extent to which humans are explicitly aware of how we make such decisions; the biasing influence of pre-existing emotional labels; and the extent to which emotion-based systems are anatomically and functionally independent of episodic memory.

Although it might seem that people with schizophrenia would perform poorly on measures of emotion-based learning, several studies have shown normal levels of performance on the Iowa Gambling Task (IGT; C. E. Y.

The key role of emotion in complex decision-making is commonly assessed using the Iowa Gambling Task, and has recently been a substantial research topic in neuropsychology. However, the question of subjective experience on such emotion-based learning measures has yet to be fully investigated, largely because previous studies have focussed primarily on behavioral performance measures. The present study investigated subjective experience on the Gambling Task, using a more systematic and quantitative method than that previously employed: evaluating the ability of participants to 'interrogate' emotion-based learning systems.

In the last decade, the Iowa Gambling Task (IGT) has become a widely employed neuropsychological research instrument for the investigation of executive function. The task has been employed in a wide range of formats, from 'manual' procedures to more recently introduced computerised versions. Computer-based formats often require that responses on the task should be artificially delayed by a number of seconds between trials to collect skin-conductance data.

The Iowa Gambling Task has been widely used in the assessment of neurological patients with ventro-mesial frontal lesions. The Iowa Group has claimed that the Gambling Task is too complex for participants to follow using cognition alone, so that participants must rely on emotion-based learning systems (somatic markers). The present study investigates whether similar tasks can be performed without direct somatic markers.

The Iowa Gambling Task (([Bechara et al., 1994]) is an effective neuropsychological tool for the assessment of 'real-life' decision-making in a laboratory environment. It has been employed in a wide range of circumstances, though researchers have sometimes employed real money reinforcers instead of the facsimile (or 'monopoly'-type) money used by.
