This article describes the disparate research findings regarding the effects of stimulant medication in subsequent substance abuse and dependence. A minimum of 4 to 5% of children in the United States will be diagnosed with ADHD; thus it is important for parents to be informed when making decisions about the use of stimulant medication to treat…

Female survivors of domestic violence may experience symptoms of low self-esteem, insecurity, difficulty with problem solving, low self-efficacy, and high anxiety with regard to their economic future. Creative methods are needed to help abuse survivors overcome these factors so they are able to set and attain career goals. Equine assisted therapy…

Childhood cruelty to animals is a symptom of conduct disorder that has been linked to the perpetration of violence in later life. Research has identified several factors associated with its etiology, including social factors. However, no cross-cultural studies on this phenomenon have been reported. This study investigated childhood cruelty to…

This study evaluated the effects of therapeutic horseback riding on social functioning in children with autism. We hypothesized that participants in the experimental condition (n = 19), compared to those on the wait-list control (n = 15), would demonstrate significant improvement in social functioning following a 12-weeks horseback riding…

This study investigated the effects of workshop and lecture methods on pastoralists' learning in Ilam Province, west of Iran. A quasi-experimental research method and non-equivalent control group design was used. Sixty pastoralists participated in this study. An open-ended questionnaire was used as the instrument of the study and found to have…

This article reviews the literature and presents data on sensory deprivation stress and supplemental stimulation of the rat pup and the preterm neonate. (PCB)

The small, uneaten, slate-gray, pointed-nose animal that is distasteful to the cat because of foul-tasting scent glands is the shrew. Describes the short-tailed shrew's physical characteristics, lifespan, habitat, eating habits, and senses. (ERB)

Following a letter of transmittal, this document presents General Agent of Education in Alaska, Sheldon Jackson's ninth annual report on the introduction of reindeer into Alaska. Jackson notes that 1899 saw an unusually large number of employees connected to the herds. The discovery and opening of the Cape Nome gold mines created reindeer…

Five short notes describe the contributions to human welfare of animal research in reproductive physiology; ruminant nutrition; meat science research; genetics and animal breeding; and recycling food by-products. (AL)

Nature projects that can be carried out in winter are described. (DB)

The author suggests eight ideal classroom pets: hamsters; turtles; snakes; spiders; frogs and toads; fish; and birds. For each he gives suggestions on selecting the pet and housing and feeding it in the classroom. Desert terrariums and home pet care training are also discussed. (SJL)

Foraging-and feeding-related behaviors across eumetazoans share similar molecular mechanisms, suggesting the early evolution of an optimal foraging behavior called area-restricted search (ARS), involving mechanisms of dopamine and glutamate in the modulation of behavioral focus. Similar mechanisms in the vertebrate basal ganglia control motor…

Rats cached pieces of cheese on four different arms of an eight-arm radial maze. On a retrieval test given 45min later, rats learned to return to arms where food was cached before arms where food had not been cached. Tests were then performed in which cache sites on one side of the maze were always modified (pilfered or degraded), but cache sites…

Humans find some sounds more pleasing than others; such preferences may underlie our enjoyment of music. To gain insight into the evolutionary origins of these preferences, we explored whether they are present in other animals. We designed a novel method to measure the spontaneous sound preferences of cotton-top tamarins, a species that has been…
