Visual Neuroscience, 1996
AbstractA model of contrast discrimination performance in human observers is developed and then extended to cover effects on performance of anticholinergic drugs. It is shown that it is necessary to assume that neural noise increases at high spatial frequencies in order to provide a satisfactory model of variations in discrimination performance with ...

The Westermarck Hypothesis and the Israeli Kibbutzim: Reconciling Contrasting Evidence
Archives of Sexual Behavior, 2015The case of the communal education system in the Israeli kibbutzim is often considered to provide conclusive support for Westermarck's (1891) assertion regarding the existence of evolutionary inbreeding avoidance mechanisms in humans. However, recent studies that have gone back to the kibbutzim seem to provide contrasting evidence and reopen the ...

The contrastive hypothesis for the acquisition of word meaning: a reconsideration of the theory
Journal of Child Language, 1987ABSTRACTThe evidence for the Contrastive Hypothesis (Clark 1980, 1983a, b, 1987, Barrett 1978, 1982) is reviewed. An examination of data from the acquisition of object words, relational words and superordinate terms reveals little support for this hypothesis that young children automatically assume that every two words in their lexicons contrast ...

Contrast media reactions: data analysis and hypothesis.
Radiology, 1980Two hundred and twenty-eight deaths due to the use of contrast media are reported, including 15 from intravenous cholangiography, 69 from angiography, 140 from urography and four other. The causes are analyzed and the various explanations for reactions to contrast media are considered.

High-contrast algorithm behavior
Proceedings of the 2007 workshop on Experimental computer science, 2007After extensive experiments with two algorithms, CPLEX and our implementation of all-integer dual simplex, we observed extreme differences between the two on a set of design automation benchmarks. In many cases one of the two would find an optimal solution within seconds while the other timed out at one hour.We conjecture that this contrast is ...

Contrasting the Social Cognition of Humans and Nonhuman Apes: The Shared Intentionality Hypothesis
Topics in Cognitive Science, 2009AbstractJoint activities are ubiquitous in the animal kingdom, but they differ substantially in their underlying psychological states. Humans attribute and share mental states with others in the so‐called shared intentionality. Our hypothesis is that our closest nonhuman living relatives also attribute some psychological mechanisms such as perceptions ...

Contrasting Multi-Source Temporal Knowledge Graphs for Biomedical Hypothesis Generation
IEEE/ACM Transactions on Computational Biology and BioinformaticsHypothesis Generation (HG) aims to expedite biomedical researches by generating novel hypotheses from existing scientific literature. Most existing studies focused on modeling static snapshots of the corpus, neglecting the temporal evolution of scientific terms.

An Overview of Contrastive Analysis Hypothesis
2015Abstract. Contrastive analysis of hypothesis also called CA is the comparison of the linguistic system of two or more languages and it is based on the main difficulties in learning a new language that caused by interference from the first language. Teaching materials can make use of contrastive analysis and the difficulties between the two languages ...

Monocular implementation of contrast negation hypothesis
1998A new neural network for lightness perception is proposed. Network is based on a interaction between boundary computation and surface reconstruction. Boundary computation is implemented using excitatory recurrent network with presynaptic inhibition which differentiate boundaries with different contrast values.
