Can tactile stimuli be subitised? An unresolved controversy within the literature on numerosity judgments.

abstract：:In four studies children were asked to read aloud a passage of randomly ordered common words with and without a coloured sheet of plastic (overlay) placed upon the page. The children's rate of reading increased with the overlay, for some children more than for others. The children were also asked to undertake a test o...

Here, in a series of three experiments, we attempt to simplify this complexity. In each...
