This experiment illustrates that the 1991 Montazer and Thomas conclusion that grip strength declines over time is incomplete 15 men performed 4 grip-strength trials with intertrial rests of 120 sec. Analysis showed that performance did not decrease over the 4 trials, on the contrary, the pattern was that of a learning curve, with a significant difference across the 4 trials, i.e., on Trial 1 grip strength was lower than on successive trials. Such a result points to the importance of 'warming-up' the muscle to obtain optimum functioning. Also, subjects should be familiar with the task and the equipment to reduce the chance of a Type I error. Implications for research are discussed.
Exogamy and endogamy are considered in terms of kinship and the selection mechanism underlying mate selection. It is argued that the contact-promoting behaviors, which are precopulatory, act as criteria for the selection of an optimum breeding partner.
A brief account is presented of the evolution of Social Skills Training at the Ulster College. It attained its origin from the Stanford model of microteaching, and its analogue of microcounselling.
A major characteristic of prenatal alcohol intake is a subsequent birth weight decrement. Experimental animal work has demonstrated that nutritional effects apart, there is a strong, direct alcohol effect responsible for this decrement. Consistency in this effect of birth weight decrement has been demonstrated in a range of species. Early work with animals had equally demonstrated that this effect can be transitory and that catch up is possible. Quite recently, human studies have supported such animal findings to the extent that now we need to question even more strongly our approach required for counselling on alcohol consumption during pregnancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
