Our major goal is to account for some simple digit-recall data with a theory that integrates two models from two scientific traditions. The random-sampling model, founded in the memory and attention literature, holds that (1) stimulus features are randomly sampled throughout the course of stimulus presence and (2) proportion correct recall is equal to the ratio of sampled features to total feat...

Studies of tree recruitment are many, but they provide few general insights into the role of recruitment limitation for population dynamics. That role depends on the vital rates (transitions) from seed production to sapling stages and on overall population growth. To determine the state of our understanding of recruitment limitation we examined how well we can estimate parameters corresponding ...

Experimental studies of bioelectric effects caused by single intense, ultrashort (nanosecond and even subnanosecond), square wave pulses indicate that the product of electric field amplitude and pulse duration, i.e., the electrical impulse, can be considered a similarity or scaling factor. An explanation for this scaling law is based on the assumption that any bioelectric effect in this paramet...

BACKGROUND AND OBJECTIVES Understanding the time course of sexual partnerships is important for understanding sexual behaviour, transmission risks for sexually transmitted infections (STI) and development of mathematical models of disease transmission. STUDY DESIGN The authors describe issues and biases relating to censoring, truncation and sampling that arise when estimating partnership dura...

Market microstructure theories suggest that the durations between transactions carry information about volatility. This paper puts forward a model featuring stochastic volatility, stochastic conditional duration, and jumps to analyze high frequency returns and durations. Durations affect price jumps in two ways: as exogenous sampling intervals, and through the interaction with volatility. We ad...

background: the association of duration of breastfeeding (bf)  with  weight disorders remains controversial.  this study aimed to evaluate the association of bf with anthropometric measures and weight disorders in iranian children and adolescents. materials and methods: using multistage random cluster sampling method, a representative sample of 25,000 school students were selected from urban an...

This study aims to analyze the relationship between nutritional status, type and duration of contraceptive pills, 1-month injection Depo Medroxy Progesterone Acetate (DMPA) with menstrual disorders in women childbearing age Kupang City. The method used is a quantitative cross-sectional design. sampling technique was simple random stratified sampling. results showed that there status value (P = ...

We propose a Bayesian sequential sampling model of choice reaction time (RT) which incorporates uncertainties about stimulus identity, onset, and duration. The model is the nowstandard random-walk/drift-diffusion model, with a thresholdbased response mechanism. The “substance” of the drift, however, is the posterior probability (belief) that a participant updates on a moment-to-moment basis dur...

This study examined relations between passage of time judgments and duration judgments (DJs) in everyday life, in young and elderly people, with an Experience Sampling Method. The DJs were assessed by verbal estimation and interval production measures. The results showed no difference between young and elderly people in judgments of rate of passage of time, a result contrary to the conventional...
