How to Design Experiments in Animal Behaviour

In the second article in the series, I will describe how the young Karl von Frisch, later to become another founding father of ethology and Nobel Laureate, defied established authority to design simple yet logically clever experiments to show that honey bees indeed have colour vision. His experiments forever changed our view of animals and also the way experiments in animal behaviour are designed. It might interest readers to know that Karl von Frisch’s experiments described in this part inspired Tinbergen’s experiments described in the previous article in this series.

The inveterate tinkerer: Bubble raft

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science.In this series of articles, the authors discuss various phenomena in fluid dynamics, which may be investigated via tabletop experiments using low-cost or home-made instruments. The sixth article in this series explores crystalline defects and motion of dislocations using bubble rafts. Materials

How Automatically Do Readers Infer Fictional Characters' Emotional States?

We propose that reading stories, such as a narrative about a character who takes money from a store where his best friend works and who later learns that his best friend has been fired, stimulates readers to activate the knowledge of how the character feels when he finds out that his best friend has been fired from a job for something he did. In other words, we propose that readers infer fictional character's emotional states. In this article, we first review two series of laboratory experiments (Gernsbacher, Goldsmith, & Robertson, 1992; Gernsbacher & Robertson, 1992) that empirically tested this hypothesis by measuring participants' reading times to target sentences that contained emotion words that matched (e.g., guilt) or mismatched (e.g., pride) the implied emotional state. We then present a third series of laboratory experiments that tested how automatically such knowledge is activated by using a divided- attention task (tone-identification, per-sentence memory load, or cumulative memory load) and by comparing target-sentence reading time when the emotional state is explicitly mentioned versus only implicit.

How to Design Experiments in Animal Behaviour

In this series of articles, I will introduce the reader to the science of ethology, somewhat indirectly by describing simple experiments, both old and new, designed to understand how and why animals behave the way they do. My emphasis will be on the design of the experiments and my goal will be to motivate readers not only to think about the design but also to come up with alternatives and improvements. Motivated readers can indeed replicate some of these experiments even if they end up replacing the study animal or the behaviours of interest with their own favourite choices. In the first part of the series, I describe how Niko Tinbergen — Nobel Laureate and one of the founding fathers of ethology (the science of animal behaviour) — designed remarkably simple experiments to successfully understand how digger wasps find their own nests in a complex habitat also consisting nests built by other wasps.
