SmartCap Measures Workers' Brainwaves Not Intelligence

You have all heard the phrase: "Get your brains tested." Well, perhaps it is mainly the older generation who heard it in their youth. However, some Australian workers are having their brains scanned.
SmartCap
Should These SmartCaps stay where they are - in the cupboard
They are wearing special baseball caps that measure brain activity. researchers are looking for signs of tiredness. It is fatigue that is the precursor to an accident. The problem is - are workers to be paid to have a rest? Of course, employers will say no. We could be heading toward a workplace rumble here!

Ironically the new device is called a SmartCap, when there is nothing intelligent about it. It certainly does not measure intelligence. When tiredness is detected an alarm goes off that everyone in the vicinity can hear. Are employees expected to lie down and rest where they are standing?

Accident Witnesses May Not Remember the Truth

Witnesses in a trial may reiterate what they believe to be an accurate statement of what happened before their very eyes, but this may be distorted if they were stressed at the time. During a bank robbery or hostage taking they will be stressed if they are the victims.

Certain parts of the brain are known to be affected, when a memory (engram) is created. Once a memory is made and filed, recall of this is the same whether the engram is true or false.

In mice the chemical structure of a memory of a bright flashing light was identified. This chemical "program" was induced in some mice. When electric pulses were applied to the animal's feet for memory recall, those with the program froze in shock, while the others reacted normally. Obviously, the mice deemed the false memory to be absolutely real. Placement of the memory is fixed and immediate.

Human memories tend to improve with age. As time goes by, what actually happened and what really occurred during childhood is rosier. Bad memories affect health. Amnesia could be a safety mechanism to forget a very bad, painful memory.

Fish Are Intelligent and Can Remember

For years scientists told us what we wanted to believe - that fish have short memories only lasting one lap of the fish bowl. Now the truth has got out. They are intelligent creatures who can learn to do things and can even deceive other animals. Once attacked, if they escape, they remember which predator tried to kill them. Unlike humans, however, there is a cost when they use their intelligence. If they are given one fish for food they are very efficient in catching it, but if given two types of prey they apparently become confused and their effectiveness declines.

Fish interact in a social way. They recognize familiar others and modify their behavior accordingly. Siamese fighting fish will take advantage of a weak fighter by observing fish fights and readily attacking the weaker fish. Fish that clean others act busy when potential "customers' are watching. In a way they advertise.

The myth about fish having no memory or even intelligence is most likely promulgated to justify fishing, when fishermen say it is alright to jab in a hook or gut a fish because they "don't feel any pain".

An example of fish learning occurred when Professor Charles Erikson fed fish after calling to them by saying "fish-fish". When he returned five years later he called to them and some fish came to the surface expecting food. Examples of smart thinkers are trigger fish which use tools to trick prey that hunt them, and frillfin which jump back into rock pools to avoid birds.
