Exam 16: Communications: Channels and Functions

Presenting each component of a multimodal display individually to a recipient and seeing how the recipient responds will allow you to determine whether the messages conveyed in the display are

Auditory signals usually allow

There is some research evidence that natural selection for distinctly different signals has been strongest

Srinivasa and colleagues (2000) found that bees use visual cues to estimate how far they have traveled so that information regarding distance to the food source can be communicated to the other bees once they return to the hive. The researchers determined this by training bees to fly into tunnels in order to reach a feeder and then manipulated the

Which of the following would NOT be considered a cost of multimodal communication?

If honeybees are provided with a scented sucrose solution only 10 meters east of the hive, the scout will return to the hive and performed a round dance. During the test period, if scented plates are placed north, south, east, and west of the hive, the recruits are likely to arrive

If it were crucial that you quickly communicate with one particular conspecific in a way that would guarantee that you would not attract the attention of a nearby predator, you should probably use a(n) ______ signal.

A method of producing sounds called stridulation results from

If a signal of relatively long duration is needed, an ideal candidate might be which of the following?

The name most closely associated with the study of bee communication is

Since electrical signals are not carried away from the sender, they

Substrate vibration can create seismic signals that can be used to convey information about

Herntenstein and colleagues (2006) describe a study in which human subjects were asked to send a tactile signal to another person that conveyed one of 12 different emotions. The recipient of the signal was then supposed to choose which of the 12 the sender was trying to communicate. Study participants performed above chance for each of the following emotions except

Uetz and colleagues (2002, 2008) presented isolated visual and seismic components of the male brush-legged wolf spider's multimodal courtship display to females and concluded that the components in both channels appear to contain largely redundant information. They concluded this because

If you were a vervet monkey (Cercopithecus aethiops) and heard an adult perform a "leopard" call, you would probably

Some animals make sounds that humans cannot hear. Some of these sounds fall below the frequency threshold for human hearing, i.e., at frequencies less than about 20 Hz. These are usually described as

Some alarm calls cause those who hear it to congregate into a group to defend a resource or drive off a predator rather than causing the others to flee. These assembly calls, when compared to "flee" signals, tend to be

Most elephant calls are infrasonic, which works well for them because, when compared with ultrasound, infrasound

If honeybees are provided with a scented sucrose solution 150 meters east of the hive, the scout will return to the hive and performed a waggle dance. During the test period, if scented plates are placed north, south, east, and west of the hive, the recruits are likely to arrive

Many believe that a definition of communication must include
