Reply to Beck and Ivry

Illusory conjunctions die hard: a reply to Prinzmetal, Diedrichsen, and Ivry (2001).

M. Donk (1999) showed that various data patterns that have been considered as evidence for the existence of illusory conjunctions may be due to errors of target-nontarget confusion, an account that challenges the mere existence of illusory conjunction. In a reply, W. Prinzmetal, J. Diedrichsen, and R. B. Ivry (2001) argued against this conclusion, claiming that some earlier findings can be expl...

Which Counterfactuals Matter? A Response to Beck

This theory allows us to explain why children pretend, why they create fantastical pretend worlds, and how pretend play and counterfactual reasoning can help children to learn about the causal structure of reality. ...
