Can participants retrieve information about the 2nd of 2 stimuli while they are processing the 1st? Four experiments suggest they can. Reaction times to the 1st stimulus were faster if it came from the same category as the 2nd than if it came from a different category. This category-match effect was observed for letter-digit discrimination (Experiment 1), magnitude and parity judgments about di...

Data from the 1985 Spanish Survey of Fertility including 8789 women aged 18-49 years is used to examine the timing of 1st births from marriage. Premarital births are excluded. Life table estimates are used to describe trends and differentials. A piecewise constant hazard model, which assumes a constant transition rate within each duration segment (0-7, 8-12, 13-18, 19-24, 25-36, and 37-48 mo...

Comparisons of 1st- and 2nd-order stereopsis have typically employed isolated, or local, narrow-band targets. While these experiments have revealed a great deal about the distinction between these two types of processing, such stimuli are rare in the natural environment. Instead, local disparity signals are more likely to be part of extended surfaces that very smoothly in depth. The aim of the ...

Background The windlass mechanism was described as the effect caused by the extension of the first metatarsalphalangeal joint (1st MTPJ). Quantify the degrees of movement produced in the leg by means of the Bioval® sensor system, after performing two measurements in the 1st MTPJ, 45° extension and maximum extension. Methods Tests-post-test study with just one intervention group, performed in ...

OBJECTIVE Assessment of short stature in many instances is based on a comparison with the Centers for Disease Control's (CDC) growth curves. The secular trend for height may limit the utility of CDC data for contemporary populations. We investigate the effect of the secular trend on Australian and US populations. DESIGN Describe CDC-defined height SDS distributions of contemporary populations...

BACKGROUND Recent reports indicate a decline in rates of Fetal Alcohol Syndrome (FAS) among Alaska Native and American Indian (AN/AI) infants. Nevertheless, AN/AI infants remain disproportionately impacted by the effects of prenatal alcohol exposure. METHODS AN/AI pregnant women in their 3rd trimester completed a questionnaire on demographic data and the amount and frequency of their alcohol ...

BackgroundEach year about 32.4 million of children are born with low birth weight, which is below the 10th percentile for their gestational ages; moreover, about fifteen million of them are premature. Actually, about 60% of neonatal deaths occur in low birth weight neonates related to their prematurity. This study aimed to determine the neonatal death rate and the most common causes of the hosp...

The twisted-cord illusion is a powerful demonstration of interaction between 1st-order (luminance-defined) and 2nd-order (contrast-defined) orientation processing. The perceived orientation of contrast-defined objects is pulled towards their 1st-order orientation content when the difference in orientation is small (Fraser effect), yet is pushed away from the 1st-order content at large orientati...
