Pigeon concept formation: successive and simultaneous acquisition1

Interocular transfer of simultaneous but not successive discriminations in the pigeon

Pigeons were trained with one eye covered on each of two types of visual discriminations. They then were tested for interocular transfer with the previously covered eye. Transfer was shown by every pigeon trained on a simultaneous discrimination, while lack of transfer was shown by these same pigeons when trained on a spatial conditional (successive) discrimination. As opposed to the pigeon, an...

Successive Minima and Best Simultaneous Diophantine Approximations

We study the problem of best approximations of a vector α ∈ R n by rational vectors of a lattice Λ ⊂ R whose common denominator is bounded. To this end we introduce successive minima for a periodic lattice structure and extend some classical results from geometry of numbers to this structure. This leads to bounds for the best approximation problem which generalize and improve former results.

Discrimination of simultaneous and successive tones

A series of discrimination tasks involving simultaneous and successive presentation of pairs of piano notes was given to 27 Ss. The listeners exhibited less-than-perfect ability to "hear out" the component notes in simultaneous presentations. This finding, in agreement with the results of previous investigators, demonstrated the limitation of Ohm's law of acoustical analysis. It was also found ...
