Researchers at the University of Nottingham’s School of Psychology published a study in the Journal of Neuroscience demonstrating that punishment can be an effective performance enhancer. “This work reveals important new information about how the brain functions that could lead to new methods of diagnosing neural development disorders, such as autism, ADHD, and personality disorders, where decision making processes have been shown to be compromised,” study leader Dr. Marios Philiastides said in a press release. Philiastides' team sought to test how well humans make decisions based on vague information, such as sights and sounds, and how the idea of punishment affects that decision making

To see what happens in a person’s brain when he or she makes a decision, researchers used an electroencephalogram (EEG): essentially a rubber swimmer’s cap fitted with electrodes that measure electrical activity in the brain. Study participants were hooked up to the EEG and given a simple task: determine whether a blurred shape behind a rainy window is a human or something else. If a participant guessed incorrectly, he or she was fined. Researchers found that participants gave more correct answers as the fine amount increased. To the researchers, this suggested that punishment increases a person’s performance in much the way a reward does.

The EEG machine revealed that distinct parts of the brain became active when the punishment was applied. Researchers said the timing of this activation showed that the punishment doesn’t influence how the brain processes evidence, but it does impact how the brain decodes information at a later stage in the decision making process.

1. Gotta think about this, I guess:

'doesn’t influence how the brain processes evidence, but it does impact how the brain decodes information at a later stage in the decision making process.'

2. I think instilling fear of being fired, is certainly a motivator for many employees.

who live kinda sorta hand-to-mouth. I also suspect a cat-of-nine tails can be a motivator...

Establishing that punishment works as a motivator, as an academic exercise, leaves open the question of whether or not it is moral and acceptable.

3. Right, and a thought I have:

Might their results indicate 'fear' of punishment results in faster responses, and not better/more correct responses?

As to moral and acceptable, really depends on nature of the 'punishment.' A fine is way different from a whipping, and would surely evoke a different response from me (I imagine.)

4. THe question of motivating 'better' work is really a good one. n/t
