Taxon sampling revisited [PDF]

Nature, 1999
Phylogenies that include long, unbranched lineages can be difficult to reconstruct. This is because long-branch taxa (such as rapidly evolving species) may share character states by chance more often than more closely related taxa share derived character states through common ancestry1. Despite Kim's warning that added taxa can decrease accuracy2, some

The taxonicity of schizotypy: A replication.

Journal of Abnormal Psychology, 1995
P.E. Meehl's model (1962, 1990) of schizotypy and the development of schizophrenia implies that the structure of liability for schizophrenia is dichotomous, hypothesizing that a "schizogene" determines one's membership in a latent class (or taxon; P.E. Meehl & R. R. Golden, 1982).

A CLADISTIC TEST OF THE TAXON CYCLE AND TAXON PULSE HYPOTHESES

Cladistics, 1990
Abstract— A species' habitat preference is intcrpretablc both as a response to present‐day conditions and as a result of evolutionary response to historical conditions. The taxon cycle and taxon pulse have been proposed as hypotheses that allow prediction of patterns of habitat specialization within a lineage.

Testing the dissociative taxon

Psychiatry Research, 2004
A dissociative taxon has been proposed by Waller et al. (1996) to help identify individuals experiencing pathological dissociation. We studied the frequency of taxon membership and tested its validity. A total of 276 students and 204 psychiatric inpatients completed the Dissociative Experiences Scale (DES).

The Taxon Concept: Is it Taxonic?

Psychological Reports, 2008
The question of whether the concept of a “taxon” (a nonarbitrary latent category) is itself categorical, or is a matter of degree, has lain dormant within taxometrics. I analyze the problem conceptually. Part of the meaning of “taxon,” I hold, goes beyond the manifest statistical properties of admixed probability distributions; any of certain forms of

What's in a Taxon?

Journal of Abnormal Psychology, 2004
Whether taxometrics yields inferential knowledge to something latent is partly but not wholly a semantic question. Although the single variables are manifest indicator scores of individuals, the statistics computed from them via postulates of the formalism are not mere data summaries and will be incorrect or meaningless if the structural conjectures ...

The notions of composite taxon and of non-taxon

Palaeogeography, Palaeoclimatology, Palaeoecology, 1993
Abstract Presently, for certain groups of organisms, the status of a taxon lends itself (or could lend itself) to discussion. It is not only the classic case of composite taxons and ancestral groups, but also that of new units which have been created from the cladistic analysis, which for the most part have neither a name nor a place in traditional ...

The Taxon Concept is Not Taxonic: Response to Grove (2008)

Psychological Reports, 2009
In 2008, Grove proposed that there is a binary distinction between taxonic and nontaxonic latent variables, although causal structures which do not produce sharp category boundaries have long been recognized by Meehl and others. I argue that this position is incoherent.
