A Grey parrot ("Psittacus erithacus") had previously been taught to use English count words ("one" through "sih" [six]) to label sets of one to six individual items (Pepperberg, 1994). He had also been taught to use the same count words to label the Arabic numerals 1 through 6. Without training, he inferred the relationship between the Arabic…

In this paper we discuss some literature relating to episodic memory, future episodic thinking and mental time travel in humans and non-human animals. We discuss the concept of mental time travel and argue that the concept relies on subjective phenomena such as consciousness and on this basis is not useful when studying episodic memory and future…

In this forum I expand on the ideas I initially presented in "Extending the purposes of science education: addressing violence within socio-economic disadvantaged communities" by responding to the comments provided by Matthew Weinstein, Francis Broadway and Sheri Leafgren. Focusing on their notion of utopias and superheroes, I ask us to reconsider…

Philosophers use hypothetical duplication scenarios to explore intuitions about personal identity. Here we examined 5- to 6-year-olds' intuitions about the physical properties and memories of a live hamster that is apparently duplicated by a machine. In Study 1, children thought that more of the original's physical properties than episodic…

By growth in size and complexity (i.e., changing from more probable to less probable states), plants and animals appear to defy the second law of thermodynamics. The usual explanation describes the input of nutrient and sunlight energy into open thermodynamic systems. However, energy input alone does not address the ability to organize and create…

This activity uses inquiry to investigate how large changes in shape can evolve from small changes in the timing of development. Students measure skull shape in fetal, infant, juvenile, and adult chimpanzees and compare them to adult skulls of "Homo sapiens," "Homo erectus," and "Australopithecus afarensis." They conclude by re-interpreting their…

Teachers may be posed with such questions as, "If we evolved from chimps, why are there still chimps?" We provide teachers with answers to this and related questions in the context of the latest genetic, fossil, and behavioral evidence. We also provide references they can use to further students' understanding of human evolution and evolution in…

In this article, the author describes how placing a plastic, gazebo-style bird feeder outside the classroom windows one cold autumn morning had been a catalyst for capturing and inspiring the children's imaginations. This empowered them to explore self-directed activities that resulted in meaningful, collaborative learning for most of the school…

Two-way active avoidance (2WAA) involves learning Pavlovian (association of a sound cue with a foot shock) and instrumental (shock avoidance) contingencies. To identify regions where dopamine (DA) is involved in mediating 2WAA, we restored DA signaling in specific brain areas of dopamine-deficient (DD) mice by local reactivation of conditionally…

In this experimental study, we made an attempt to examine gender-related peer influences on childhood fear. Nine- to 12-year-old boys and girls were provided with ambiguous and positive information about novel animals and then asked to provide a subjective fear rating of the animals under two conditions: fear of one animal was assessed…

Worldwide more deaths occur due to conditions that can be ameliorated by behavior change. Changing health behaviors using models popularized in non-western countries has not proven particularly successful. The purpose of this study was to test variables elicited during qualitative interviews and cultural conversations to develop a model of health…

This study aims at performing a sample application of the educational use of Facebook as a social networking site in Animal Physiology classes, and to determine student's' views on the application. The research sample was composed of 29 third year undergraduate students attending the Biology Education Department of Hacettepe University. The…

In the lesson on which this practical article is based, third grade students constructed a "lift-the-flap" page to explore food webs on the prairie. The moveable papercraft focused student attention on prairie animals' external structures and how the inferred functions of those structures could support further inferences about the…

Students' explanations of biological phenomena are frequently characterized by disconnects between levels and confusion of levels. The purpose of this research is to investigate the effects of a hands-on lab activity that aims at fostering the ability to reason across levels. A total of 197 students (18 years of age) participated in a randomized,…

Critically thinking about scientific data to form opinions on controversial issues in environmental health is crucial in undergraduate education in the field. An assignment paired with a "flipped" classroom activity was designed to impart knowledge on how to search the primary literature and extract data that can help formulate a point…
