ERP and behavioral changes during the wake/sleep transition

Abstract: Event-related potentials (ERPs) following infrequent and frequent stimuli were studied as subjects moved from wakefulness to sleep. Subjects were instructed to respond to the infrequent "target" stimuli (attend condition) or to ignore the stimuli (ignore condition). Parietal P300, prominent following target ERPs in wakefulness under the attend condition, disappeared in association with reduced behavioral responsiveness and emergence of a central negativity (N350). The N350 and preceding and following positivities (P220 and P450) became the dominant feature of both target and nontarget ERPs under both attend and ignore conditions. The P220-N350-P450 complex was larger and peak latencies were shorter under the attend condition. Peak amplitudes tended to be larger following targets, especially under the attend condition. The findings suggest that, although the processes underlying P300 are less likely to be engaged, processing of stimulus deviance and task relevance continues in sleepiness and sleep, and is reflected by variance in N350 and related activity.

Disneyland Dads, Disneyland Moms?: How Nonresident Parents Spend Time With Absent Children

Abstract: Using data from the 1987-1988 National Survey of Families and Households, this study examines gender differences in how nonresident parents spend time with their absent children. Whereas nonresident fathers are often perceived as “Disneyland” parents, nonresident mothers are generally considered to be more involved in their children's daily lives. However, results suggest that nonresident mothers and fathers exhibit a similar pattern of participation in activities with their absent children, controlling for sociodemographic and family characteristics. Most nonresident parents either engage in only leisure activities with their children or have no contact. Only about one third of parents mention school among activities they participate in with their child. These findings indicate that nonresident parent-child interaction patterns may be the result of circumstances surrounding the nonresidential role rather than the gender of the parent.

Futures trading, spot market volatility, and market efficiency: The case of the Korean index futures markets

Abstract: We examine the effect of the introduction of index futures trading in the Korean markets on spot price volatility and market efficiency of the underlying KOSPI 200 stocks, relative to the carefully matched non-KOSPI 200 stocks. Employing both an event study approach and a matching-sample approach for the market data during the period of January 1990–December 1998, we find that the introduction of KOSPI 200 index futures trading is associated with greater market efficiency but, at the same time, greater spot price volatility in the underlying stock market. We also find that KOSPI 200 stocks experience lower spot price volatility and higher trading efficiency than non-KOSPI 200 stocks after the introduction of futures trading. The trading efficiency gap between the two groups of stocks, however, declines over time and vanishes following the addition of options trading. Overall, our results suggest that while futures trading in Korea increases spot price volatility and market efficiency, there exists volatility spillover to stocks against which futures are not traded. We provide several factors unique in the Korean markets including circuit breakers, sidercar system, restrictions on foreign ownership, and inactive program trading as potential factors to explain some of our puzzling evidence. We further consider the potential effect of changes in daily price limits utilized by the Korea Stock Exchange during the testing period on our empirical findings. © 2004 Wiley Periodicals, Inc.

Metamemorial predictors of memory performance in young and older adults.

Abstract: The relationship between aspects of knowledge about memory and immediate and delayed recall on prose and word-list tasks was examined Ss were 100 young and 100 older adults Vocabulary ability was screened Memory knowledge was assessed by the Metamemory in Adulthood (MIA) scale and the Short Inventory of Memory Experiences (SIME) Capacity and change measures of the MIA correlated with most dimensions of the SIME for both age groups The anxiety measure of the MIA correlated with SIME measures only for the young Regression analyses showed that strategy (MIA) predicted performance only for young adults, change (MIA) predicted performance only for older adults, and capacity (MIA) predicted performance for both age groups Metamemory variables accounted for equivalent amounts of variance in both prose and word-list tasks, although there was an indication that prediction was slightly better for prose Future researchers need to address the apparent increase in affect-related predictors of memory performance
