Tribe Trifolieae: Evidence from Seed Characters

Categorical membership modulates crowding: evidence from characters.

Visual crowding is generally thought to affect recognition mostly or only at the level of feature combination. Calling this assertion into question, recent studies have shown that if a target object and its flankers belong to different categories crowding is weaker than if they belong to the same category. Nevertheless, these results can be explained in terms of featural differences between cat...

Unconscious Grouping of Chinese Characters: Evidence from Object-based Attention*

To show that, in reading, a fundamental and unconscious perceptual process occurs beyond the current fixation, we examined whether peripherally presented characters of Chinese words in such extreme viewing conditions could be grouped when some characters were rendered invisible while others were visible. We presented a pair of two-character Chinese words and indexed whether the visible and invi...

Seed Vitality and Other Cotton Characters as Affected by the Age of Seed.

Phylogeny of seed plants based on evidence from eight genes.

Relationships among the five groups of extant seed plants (cycads, Ginkgo, conifers, Gnetales, and angiosperms) remain uncertain. To explore relationships among groups of extant seed plants further and to attempt to explain the conflict among molecular data sets, we assembled a data set of four plastid (cpDNA) genes (rbcL, atpB, psaA, and psbB), three mitochondrial (mtDNA) genes (mtSSU, coxI, a...
