This paper describes experiments designed to investigate long-term behavioral consequences for offspring of changes in maternal behavior directed toward them as pups. Specifically, the hypothesis was considered that experimentally induced alterations in maternal behavior would result in general and wide-ranging effects on offspring development, including(More)
Socioscientific issues encompass social dilemmas with conceptual or technological links to science. The process of resolving these issues is best characterized by informal reasoning which describes the generation and evaluation of positions in response to complex situations. This article presents a critical review of research related to informal reasoning(More)
It has been hypothesized that the planktonic community of the North Pacific subtropical gyre (NPSG) underwent a ''domain shift'' in the early 1980s in which phytoplankton of the domain Eukarya were supplanted by phytoplankton of the domain Bacteria, primarily Prochlorococcus. P limitation of eukaryotic phytoplankton was implicated as the causative chemical(More)
The Tidal Model has been implemented in Rangipapa, a regional secure mental health forensic unit in New Zealand. A phenomenological study was undertaken to obtain reflective description of the nursing care experience from the perspective's of four Registered Nurses and four Special Patients. Five major themes were identified that appeared to capture the(More)
The effects of neonatal exposure to medroxyprogesterone acetate on later play behaviour was studied. The experiments reported here indicate that animals of both sexes exposed to the hormone neonatally show lower levels of rough-and-tumble play in the prepubertal period. The effect is primarily one on play initiation: the organisation of play behaviour once(More)
This paper reports changes in maternal behavior of rats following progestin treatment of the neonates. There have been recent reports that hormonal treatment of pups can alter maternal behavior, particularly licking of pups, and that such effects might have implications for the later development of those pups. Accordingly, the major objective of the(More)
The present paper reports an investigation of patterns of exploratory behavior shown by laboratory-bred Spiny Mice (Acomys cahirinus) when given access to a large, novel arena. The aim was to test hypotheses suggested by our previous work with this species. Previous experiments in which the exploratory behavior of Acomys was compared with that of Mus had(More)
It is demonstrated that the behavior/morphology interface can be studied in controlled experiments. The normal locomotor behavior of the laboratory mouse (Mus musculus) was modified so that animals were restricted to either a plantigrade, 'non-climbing', control environment or an experimental, suspensory, 'climbing' environment. Distinct scapular correlates(More)
Developmental changes in patterns of exploration by infant spiny mice, Acomys cahirinus are described. These were investigated using an unbaited radial maze and under three odor conditions; that is, animals were tested in the presence of either familiar (own) odors, unfamiliar conspecific odors, or no odors (washed floor). Two hypotheses were tested. The(More)
The present paper reports sex differences in exploratory behaviour by infant Spiny Mice, Acomys cahirinus, that may, in part, be related to differences in maternal behaviour towards pups; like some other rodents, mother Acomys differentiate behaviourally between male and female pups. In Experiment 1 infant Acomys were allowed to explore a novel arena. This(More)
