New cards

Define cognition

mental processes for what animals think and how they think it

crediting animals with human characteristics

3
New cards

Define anthropocentrism

having recognized that animals are not people, still seeing them from our human perspective

4
New cards

Explain Morgan Canon

don’t assume complex mental abilities if simpler explanations suffice, ended up being a overcorrection

5
New cards

What is the modern approach to animal cognition

animals have unique capabilities adapted for their lifestyle. Cognition has been theorized in mammals, birds, and octopi

6
New cards

What are the 4 cognitive domains?

self and metacognition, prospection/future thinking, executive function, and social cognition

7
New cards

What is another way to measure cognition outside of behavior? Give an example

Brain activity using functional magnetic resonance imaging, has shown numerical reasoning in corvids involves a similar brain region as humans

8
New cards

What are the 3 attributes of language

  1. Assign meanings to sounds, gestures, or symbols not directly related to the object or action

  2. Create novel combinations of symbols for communication

  3. Grammatical rules

9
New cards

Explain how Campbell’s monkey and Vervet monkey communication is different

Campbells monkeys use six call types with no symbolic association while vervet monkeys use different symbolic calls for different predators

10
New cards

What are the 2 caveats when animals use human language?

They don’t use those symbols with other animals and it may rely on a special relationship with the handler

11
New cards

Describe Chomsky’s concept of universal grammar

The idea that the grammatical structure of human language is based on something inherent in the human brain that drives similarity across languages

12
New cards

Define concept of self

recognition of self as separate from others and the environment including the ability to judge one’s actions

13
New cards

Explain the mirror test and what it’s trying to prove

Change the appearance of an animal to see if they react in a mirror to assess the ability to separate self from others

14
New cards

What is gaze following and which animals display it?

The ability to follow where another animal is looking, primates and dogs

15
New cards

Explain prospection and future planning

Involves mental time travel, anticipating outcomes and planning actions based on experience

16
New cards

Which 2 types of thinking are not involved in cognition? Which one is?

semantic and procedural memory, episodic memory

17
New cards

Explain semantic memory

Concepts and facts including language and words. Not associated with cognition as no mental time travel occurs

18
New cards

Explain procedural memory

how to do something, a series of steps in a task. Not involved in cognition

19
New cards

Explain episodic memory

recalling specific events from the past, including what, when, and where, allows reflection and forecasting, the basis of cognition and mental time travel

34
New cards

Define innovation

the process that generates novel behavior or uses preexisting behavior in a new situation

New cards

What is the main communication difference between a structural and behavioral signal?

Structural signals communicate continuously while behavioral signals are produced at certain times

53
New cards

What elements are required of the sender and receiver, respectively, for communication to work?

Aside from resonant structures, frogs and howler monkeys also have vocal sacs. What is the purpose of vocal sacs?

Holds air to allow for longer duration sound

69
New cards

What is the main difference, aside from function, between alarm calls and mating calls?

Alarm calls are stereotyped with little variability while mating calls change and spread via cultural transmission

70
New cards

bats, rate, and moths use it to find mates, bats use it to hunt

73
New cards

Why might frogs sing in chorus?

Females prefer the male that sings first, but there needs to be a distinct break between calls

74
New cards

Why might crickets sing in chorus?

Males save energy by hanging around other males who are already trilling

75
New cards

How do animals cope with noise?

Limiting the frequency range they can hear, signaling at certain times of day, and neural processes that filter signals

Is fluorescence a pigment or a structural color?

both

91
New cards

What are the two strategies to deal with visual noise?

Signal divergence helps to stand out from background and camouflage uses visual noise to blend in

92
New cards

Features of electrical signal communication

Work well in murky water, used for communication, detecting prey, and navigation

93
New cards

There are two forms of electric use in fish, strongly electric and weakly electric fish. They use their electricity differently, explain how.

Strongly electric fish use electricity mostly for predation and defense while weakly electric fish use mostly for communication and electrolocation

94
New cards

Explain runaway sexual selection

If one sex prefers mates to have a strong signal, selection will favor making that signal bigger beyond what is actually necessary

95
New cards

Explain supernormal stimulus

Animals are attracted to stimulus that are greater in magnitude than normal stimulus

96
New cards

What are the two main instances of dishonest signals within a species

young exaggerate their actual needs and in mating sneaking males lurk near signaling males to get mates without producing costly signals

97
New cards

Explain the handicap principle

A signal is honest if it is costly to produce

98
New cards

Explain two examples of deceitful signals between species

mimicry and falsely signaling injury or alarm

99
New cards

How does communication evolve in the sender

to give messages that benefit the sender but minimize cost or effort for communication

100
New cards

How does communication evolve in the receiver

to enhance the information obtained from a signal and discriminate honest from deceitful signals
