The authors present the central capacity sharing (CCS) model and derive equations describing its behaviors to explain results from dual-task situations. The predictions of the CCS model are contrasted with those of the central bottleneck model. The CCS model predicts all of the hallmark effects of the psychological refractory period (PRP) pardigm: -1 slope of the PRP effect at short stimulus on...

Stimuli that are clearly positive or negative (hence valence-laden stimuli) have the potential to interrupt unrelated task processing. A typical example is the emotional Stroop effect (ESE) in which responding to a certain task feature (e.g., color) is delayed by the presentation of task-irrelevant valent stimuli (e.g., negative pictures) compared to valence-neutral stimuli. Here we scrutinize ...

background: implantation failure is the most important cause of recurrent in vitro fertilization/intra cytoplasmic sperm injection (ivf/icsi) failure. several reports suggest that intercourse during the peritransfer period might improve pregnancy rates. this study is designed to determine whether intercourse during the peritransfer period will improve pregnancy and implantation rates in patient...

Introduction The effects of antidepressant and antipsychotic medications in the perinatal period both mothers children have been a subject interest for many decades. Risks benefits should be considered according to illness stage, trimester pregnancy/ postpartum period, neonatal outcomes. Objectives Our goal was summarize knowledge about use antidepressants antipsychotics period. To illustrate c...

The pregnancy results of 17337 inseminations carried out in a dairy herd near Cairo over a period of 12 years were retrospectively analyzed in relation to environmental temperature and temperature-humidity index (THI). The overall average of pregnancy rates to all inseminations was significantly (P

Bisphenol A (BPA) is among the better-known endocrine disruptors. BPA is used in various food-contacting materials and is easily eluted into food; as a result, we are exposed to BPA on a daily basis. In adults, BPA is metabolized and eliminated rapidly from the body. However, numerous reports suggest that fetuses and young children are susceptible to BPA. One of the concerning adverse effects o...

During the perinatal period, compromises in sleep duration and quality are commonly reported by women and confirmed by objective measurements of sleep. Self-reported poor sleep has been associated with concurrent mood disturbance and with increased risk for future mood problems during pregnancy and the postpartum period. Findings on the relationship between objectively measured sleep and mood i...

OBJECTIVE Bipolar disorder affects 0.5%-1.5% of individuals in the United States. The typical age at onset is late adolescence or early adulthood, placing women at risk for episodes throughout their reproductive years. General guidelines for the treatment of bipolar disorder are available from the American Psychiatric Association, but additional issues arise when these guidelines are applied in...

Pregnant women and their unborn children are a population that is particularly vulnerable to bacterial infection. Physiological changes that occur during pregnancy affect the way women respond to such infections and the options that clinicians have for treatment. Antibiotics are still considered the best option for active infections and a suitable prophylaxis for prevention of potential infecti...
