Where Do Relations Come From?
Relational knowledge is a hallmark of human cognition and the subject of a vast body of research. In this paper we argue that existing accounts of relations are inadequate because they have little to say about how relations arise in the rst place and because they tend to be limited to particular sorts of relational tasks. We present a new approach to the learning and representation of relations...
متن کاملWhere Do Social Preferences Come From?
Where do preferences for fairness come from? We use a unique field setting to test for a spillover of sharing norms from the workplace to a laboratory experiment. Fishermen working in teams receive random income shocks (catching fish) that they must regularly divide among themselves. We demonstrate a clear correlation between sharing norms in the field and sharing norms in the lab. Furthermore,...

RB, a patient with probable Alzheimer's disease, makes continuous perseverations of single letters when writing (e.g. fruit-->fruuit), particularly on high frequency letters. An analysis of her errors reveals that her perseverations do not reflect letter substitutions or transpositions, nor do they suggest difficulty with geminates. No continuous perseverations were found in oral production, in...

Theoretically, it provides a concrete evolutionary psychological theory of son-daughter preference: why pe...
متن کاملWhere Do Features Come From?
It is possible to learn multiple layers of non-linear features by backpropagating error derivatives through a feedforward neural network. This is a very effective learning procedure when there is a huge amount of labeled training data, but for many learning tasks very few labeled examples are available. In an effort to overcome the need for labeled data, several different generative models were...
