INB 359K: Exam 2, Names/Readings

Hoarding vs. caching?

Hoarding stores food at home; caching hides food at multiple sites for later retrieval.

What did the blue-box experiment show about caching birds?

Cachers first searched the old location; noncachers followed the blue cue.

What brain difference is associated with caching?

Caching species have relatively larger hippocampi and stronger spatial memory.

How is pit-viper infrared information used?

An IR spatial map aligns with visuomotor pathways to guide strikes.

What geographic pattern supports the newt–snake arms race?

Snake resistance is strongest where resistant snakes overlap toxic newts.

How does Polymorphus alter Gammarus behavior?

Infected crustaceans become photophilic and surface-swim, increasing duck predation.

What neural change accompanies Polymorphus infection in Gammarus?

Brain serotonin rises; experimentally increasing serotonin mimics infection behavior.

What did the zebra finch test support about E/T?

Higher feeding rate was associated with greater population growth/fitness.

What does the Drosophila for gene affect?

forR produces rovers; forS homozygotes are sitters; density changes which is favored.

What illustrates different hearing Umwelten in the gym example?

Mouse ultrasound and elephant infrasound are both outside normal human hearing.

What visual cue can bees see on sunflowers that humans cannot?

An ultraviolet bullseye.

What is FACS in the Ekman reading?

A facial coding system built from 43 basic facial muscle 'action units.'

What is a microexpression?

A very brief involuntary facial expression that can leak a concealed emotion.

What distinguishes a Duchenne smile?

A genuine smile recruits both the mouth and orbicularis oculi around the eyes.

What broad idea does the Ekman reading emphasize?

Facial behavior has involuntary components that can reveal emotion despite attempted control.

Who is associated with the 1959 'What the Frog's Eye Tells the Frog's Brain'?

Jerry Lettvin and colleagues.

Who is linked to hummingbird sweet-receptor retuning?

Baldwin et al. (2014).

Who is linked to geographic TTX resistance in garter snakes?

Edmund D. Brodie III and colleagues.

Who tested whether plants respond to herbivore vibrations?

Appel & Cocroft (2014).

Who showed glutamate/Ca²⁺ wound signaling in plants?

Toyota et al. (2018).

Who ran the Phantom Road songbird study?

Ware et al. (2015).

Who studied COVID shutdown effects on sparrow song?

Derryberry et al. (2020).

Who is associated with the ecology-of-fear human-playback study?

Suraci et al. (2019).

Who compared forest vs. woodland Great Tit calls?

Hunter & Krebs.

Who tested call duration and offspring performance in gray treefrogs?

Welch et al. (1998).

Who proposed the genic-capture framework cited in lecture?

Rowe & Houle (1996).

Who is strongly associated with Túngara frog whine/chuck research?

Michael Ryan and colleagues.

Who tested Túngara calls plus water ripples?

Halfwerk et al. (2014).

Which linguist's slide described animal communication as finite/analog/variable?

Steven Pinker.

Who is associated with universal/generative grammar in Week 9?

Noam Chomsky.

Who developed FACS together in the assigned reading?

Paul Ekman and Wallace Friesen.

Who strongly influenced Ekman's thinking about facial emotion?

Silvan Tomkins.
