Electrically triggered action potentials in the giant alga Chara corallina are associated with a transient rise in the concentration of free Ca(2)+ in the cytoplasm (Ca(2)+(cyt)). The present measurements of Ca(2)+(cyt) during membrane excitation show that stimulating pulses of low magnitude (subthreshold pulse) had no perceivable effect on Ca(2)+(cyt). When the strength of a pulse exceeded a n...

Bradley Larson,

There has been much recent inquiry into the nature of right-node raising (RNR) constructions in general and in Tagalog in particular (Sabbagh 2008 and Larson 2011a). However, the study of RNR finds itself at a crossroads as all the main analyses of the construction have been argued to be fatally empirically insufficient (Barros and Vicente 2010 and Larson 2012). In this paper I show that RNR in...

Evidence that children maintain some memories of labels that are unlikely to be shared by the broader linguistic community suggests that children's selective learning is not an all-or-none phenomenon. Across three experiments, we examine the contexts in which 24-month-olds show selective learning and whether they adjust their selective learning if provided with cues of in-context relevance. In ...

It is proposed that the mind and brain often work at a gross level and only with fine tuning or inhibition act in a more differentiated manner, even when one might think the domains being issued the global command should be distinct. This applies to disparate findings in cognitive science and neuroscience in both children and adults. Thus, it is easier to switch everything, or nothing, than to ...

THERE is considerable confusion in the medical literature as to the correct statistical method to apply to results obtained in retrospective studies in which patients with a particular disease are individually matched to control subjects. For example, in a recent paper Vessey and Doll (1968) reported on their investigations of the relation between the use of oral contraceptives and thromboembol...

Those inclined to relish in scientific controversy will not be disappointed by the literature on the effects of sleep on memory. Opinions abound. Yet refinements in the experimental study of these complex processes of sleep and memory are bringing this fascinating relationship into sharper focus. A longstanding position contends that sleep passively protects memories by temporarily sheltering t...

In “The Location Problem for Color Subjectivism,” Peter Ross argues against what he calls subjectivism — the view that “colors are not describable in physical terms, ... [but are] mental processes or events of visual states” (2), and in favor of physicalism — a view according to which colors are “physical properties of physical objects, such as reflectance properties” (10). He rejects an argume...
