Computers are routinely used to control experiments in modern science laboratories. This should be reflected in laboratories in an educational setting. There is a mismatch between the power that can be delivered by a computer interfacing card or a TTL logic circuit and that required by many practical pieces of laboratory equipment. One common way…

All animals must make choices regarding what foods to eat, where to eat, and how much time to spend feeding. Optimal foraging theory explains these behaviors in terms of costs and benefits. This laboratory exercise focuses on optimal foraging theory by investigating the winter feeding behavior of birds on the goldenrod gall fly by comparing…

The effects of rate of conditioned reinforcement on the resistance to change of operant behavior have not been examined. In addition, the effects of rate of conditioned reinforcement on the rate of observing have not been adequately examined. In two experiments, a multiple schedule of observing-response procedures was used to examine the effects…

A model of conditional discrimination performance (Davison & Nevin, 1999) is combined with the notion that unmeasured attending to the sample and comparison stimuli, in the steady state and during disruption, depends on reinforcement in the same way as predicted for overt free-operant responding by behavioral momentum theory (Nevin & Grace, 2000).…

This study examined the effects of Dolphin-Assisted Therapy (DAT) as a reinforcer for verbal operant production in children with Autism Spectrum Disorder. Three children who attended a dolphin therapy program participated in this single subject research study. Baseline data was collected for each child via a video tape provided by parents and…

Measures developed from animal models of aging may detect dementia of the Alzheimer's type in a population at-risk for Alzheimer's disease (AD). Although, by middle age, individuals with Down syndrome (DS) show an extraordinarily high prevalence of AD-type pathology, their severe idiopathic cognitive deficits tend to confound the "clinical"…

It's no secret that many school programs don't give children enough opportunity to explore the natural world--i.e., to "mess about" and to have firsthand experience with nature and animals. Not so at the Muscota New School in New York City! This innovative public elementary school actively promotes inquiry-based learning and encourages…

Children possess a genuine curiosity for exploring the natural world around them. One third grade teacher capitalized on this inherent trait by leading her students on "A Geometric Scavenger Hunt." The four-lesson inquiry investigation described in this article integrates mathematics and science. Among the students' discoveries was the fact that…

The WebQuest is a four-step process integrated at appropriate points in the Animal Studies unit. Through the WebQuest, students create a series of habitat maps that build on the knowledge gained from conducting the various activities of the unit. The quest concludes with an evaluation using the WebQuest rubric and an oral presentation of a final…

Parental care plays an important role in the emotional and cognitive development of the offspring. Children who have been exposed to abuse or neglect are more likely to develop numerous psychopathologies, while good parent-infant bonding is associated with improved resiliency to stress. Similar observations have also been reported in non-human…

Background: Measuring the self-perceptions, thoughts, hopes and inner lives of persons with intellectual disabilities (ID) has long been a research challenge. Unlike objective or projective tests, semi-projective tasks may provide persons with ID with just enough structure or cues to convey their self-perceptions in a spontaneous and unbiased…

In an effort to increase respect for certain creatures, this book profiles animals with reputations out of proportion to the actual potential harm they do. An introduction reviews the results of a survey conducted to determine which animals people generally favor or disfavor and the common beliefs held towards animals. The remainder of the book is…

The study reported in this paper intended to trace what Chinese children think about life and identify their naive theories. Fifty-eight 5-year-old children in Taiwan from 39 kindergartens were interviewed using a semi-structured instrument. Results indicate that preschool children have preconceptions about the concept of life even before entering…

Whether children shift their interpretations of a metaphor according to the social role of the speaker and the addressee of the sentence or the degree of lexicalization of the metaphor and the child's age was studied using a simple metaphorical sentence and animal terms. The 12 animal terms produced 6 lexicalized and 6 new metaphors. Metaphors…

This learning packet, one in a group of eight, was developed by the Merchants Millpond State Park in North Carolina to teach students in grades 4-6 about the habitat and lifestyle of the beaver. Loose-leaf pages are presented in nine sections that contain: (1) introductions to the North Carolina State Parks System, the Merchants Millpond State…
