Luminance and chromatic contrast sensitivity in dyslexia: the magnocellular deficit hypothesis revisited

NeuroReport, 2002
The hypothesis of a magnocellular channel deficit in dyslexia was tested. Subjects were 10-year-old dyslexics and normal readers. Psychophysical thresholds for luminance and chromatic contrasts were estimated using black and white and red and green sinusoidal gratings of various spatial frequencies, presented in static and dynamic conditions (drift and

Contrast tests of interaction hypothesis.

Psychological Methods, 1997
This article argues for the use of contrasts to test a priori interaction hypotheses in 2-way analysis of variance designs. It focuses on 3 underused types of interaction contrast tests: a "matching" pattern for cognate levels of row and column factors; the "qualitative quadratic," for monotonic profiles of means in the same direction but with opposed ...

THE CONTRASTIVE ANALYSIS HYPOTHESIS AND SPELLING ERRORS

Language Learning, 1970
The implications of three versions of the contrastive analysis hypothesis (CAH) are explored. The strong and weak forms are rejected in favor of a more moderate version which predicts the results of a spelling error analysis on the dictation section of the UCLA placement examination in English as a second language.

The Contrastive Analysis Hypothesis

TESOL Quarterly, 1970
The claim that the best language-teaching materials are based on a contrast of the two competing linguistic systems has long been a popular one in language teaching. It exists in strong and weak versions, the strong one arising from evidence from the availability of some kind of metatheory of contrastive analysis and the weak from evidence from ...

Inconsistent Probability Estimates of a Hypothesis

Experimental Psychology, 2005
Abstract. This paper studies consistency in the judged probability of a target hypothesis in lists of mutually exclusive nonexhaustive hypotheses. Specifically, it controls the role played by the support of displayed competing hypotheses and the relatedness between the target hypothesis and its alternatives. Three experiments are reported.

MARKEDNESS AND THE CONTRASTIVE ANALYSIS HYPOTHESIS

Language Learning, 1977
The purpose of this paper is to propose that the Contrastive Analysis Hypothesis (CAH) should be revised to incorporate a notion of degree of difficulty. This notion corresponds to typological markedness which can be determined independently of any particular language and independently of the facts concerning second language acquisition.

RELATIVE CLAUSES, THE ACCESSIBILITY HIERARCHY AND THE CONTRASTIVE ANALYSIS HYPOTHESIS

IRAL - International Review of Applied Linguistics in Language Teaching, 1995
Le but de cet article est d'evaluer trois propositions formulees a propos des relatives. Pour ce faire, un test a ete effectue aupres d'etudiants neerlandais en anglais venant d'assister a un cours sur les relatives. Les resultats montrent qu'il est plus difficile de relativiser des constituants dans une principale que dans une ...

Reactions to contrast media: testing the CNS hypothesis.

Radiology, 1981
Sodium iothalamate was injected intravenously into mice to test the hypothesis that reactions to contrast media are controlled by the central nervous system. Particular emphasis was placed on (a) the effect of the limbic portion of the brain on the hypothalamus and (b) the outflow through the autonomic nervous system.
