You may have heard of “g”. It’s the closest we’ve come to that elusive attribute known as “intelligence”, but it is in fact a psychometric construct, that is, we surmise its presence from the way in which scores on various cognitive tests positively correlate.
In other words, we don’t…
Autobiographical memory contains the information you have about yourself. It includes several domains:
I have two sons. One of them was a colicky baby. Night after night my partner would carry him around the room while I tried to get a little sleep. One night, for his own amusement, my partner chose a particular CD to play. Magic! As the haunting notes of the hymns of…

Humans have a long tradition of holding genes responsible for individual differences in behavior (of course, we called it "blood", then, or "family"). In the 20th century, a counter-belief arose: that it was all down to environment, to upbringing. In more recent decades, we have become…
Brain tissue is divided into two types: gray matter and white matter. These names derive very simply from their appearance to the naked eye. Gray matter is made up of the cell bodies of nerve cells. White matter is made up of the long filaments that extend from the cell bodies - the "telephone…
"I'm terrible at remembering names"
"I'm great with names, but I'm hopeless at remembering what I've read."
"I always remember what people tell me about themselves, but I'm always forgetting birthdays and anniversaries."
There is no such thing as a poor…
One theory of intelligence sees intelligence in terms of adaptiveness. Thus: "What constitutes intelligence depends upon what the situation demands" (Tuddenham 1963). Intelligence in these terms cannot be understood outside of its cultural context. Naturally…
Are you right-brained or left-brained?
One of the dumber questions around.
I think it’s safe to say that if you only had one hemisphere of your brain, you wouldn’t be functioning.
Of course, that’s not the point. But the real point is little more sensible. The whole idea…
It is clear that there are differences between the genders in terms of cognitive function; it is much less clear that there are differences in terms of cognitive abilities. Let me explain what I mean by that.
