DATA & FILE OVERVIEW
---------------------

1. File List
   A. Filename: Hch_SIN_PR_final.csv
      Short description: This spreadsheet contains the complete dataset (in long format) from phonotaxis tests in which the authors experimentally manipulated the following independent variables: the level of within-individual variation in pulse rate in male Cope’s gray treefrog calls, the level of ambient noise during the phonotaxis test, and the mean pulse rate of the alternative stimulus. In phonotaxis tests, subjects (female treefrogs) discriminated between two stimuli. In each test, we recorded the following measures of female responses: the binary choice made by the subject and the associated response latency. Individual treefrogs were tested in more than one test; the unique alphanumeric code in the “ID” column specifies which treefrog contributed the test represented by a single row of the dataset. This readme text is intended as a companion to the methods presented in the forthcoming publication.

METHODOLOGICAL INFORMATION
--------------------------

1. Description of methods used for collection/generation of data: 
A full description of the methods can be found in the forthcoming publication, which will be linked to the dataset via DOI when it comes out.

2. Methods for processing the data:
	A full description of the methods can be found in the forthcoming publication and we will refer users there for details. Latencies and binary choices are raw data that represent direct observations of the animals. For each test, the response latency was used to calculate the mean and coefficient of variation in pulse rate for the portion of the stimulus the female was exposed to during the trial (i.e., by excluding the stimulus calls that did not play prior to her decision).

3. Instrument- or software-specific information needed to interpret the data: N/A

4. Standards and calibration information, if appropriate: N/A

5. Environmental/experimental conditions:
Ambient, treefrog chorus-shaped noise was played in some test conditions. Tests were performed in a temperature-controlled anechoic chamber at 20 degrees Celsius.

6. Describe any quality-assurance procedures performed on the data:
Data were entered into a spreadsheet by one person and verified (i.e., checked for typos) by a second person. We examined the distributions of variables and checked for common sense problems (e.g., the maximum response latency must not exceed 300 s in our experimental design – a latency that exceeded this value would be double checked against the original, hand-written data sheets and, if it couldn’t be reconciled, thrown out). Custom MATLAB scripts were used to calculate the mean and coefficient of variation in pulse rate taking into account the subject’s response latency, and these values were checked by randomly selecting individual tests whose parameters we calculated by hand to verify their accuracy.

7. People involved with sample collection, processing, analysis and/or submission:
	Both authors collected the data with a research team. JCT processed and analyzed the data and submitted it to DRUM.

DATA-SPECIFIC INFORMATION FOR: Hch_SIN_PR_final.csv
-----------------------------------------

1. Number of variables: The dataset contains 25 variables (columns)

2. Number of cases/rows: 3,298 (657 trials in which females discriminated between two stimuli with equivalent nominal means and 2,641 trials in which females discriminated between two stimuli of different nominal means)

3. Missing data codes: N/A

4. Variable List

A. ID
Description: Alphanumeric identification string assigned to each individual animal. The year is coded by the last two numbers. For example, “Hch245-15” denotes the 245th frog captured in the 2015 frog season. “Hch” is a species identification string. Note that gaps in this number series occur because not every frog captured in our lab during a given year was assigned to this experiment.
                    
B. Nominal.Inconsistency.Level
Description: A word describing the nominal level of inconsistency for the trial stimuli. Each corresponds to a coefficient of variation within a stimulus.
Levels: “none”, “low”, “mean”, “high”

C. Signal.Set
Description: Number of the signal set assigned to each female. When the nominal coefficient of variation is not equal to 0, each female was assigned a “set” of unique audio tracks that only she experienced during phonotaxis trials (for “experimental” females, which discriminated between stimuli with different pulse rates: -3 vs 0, -2 vs 0, -1 vs 0 standard deviations in pulse rate; for “control” females, which discriminated between stimuli with equal nominal mean pulse rates: 0 vs 0, with a unique stimulus for each of 4 nominal levels of inconsistency). When Signal.Set is coded as 0, that female was assigned to the condition in which the nominal coefficient of variation within signals (CVw) was equal to 0; all realizations of CVw = 0 signals were identical. Signal.Set counts up to a maximum of 60 because they were numbered within levels of inconsistency (within-individual variation; nominal CVw); thus the Signal.Set is unique within assigned levels of inconsistency but numbers are re-used across levels of inconsistency.

D. Leading
Description: The name of the signal that played first in a given phonotaxis trial. This was randomized between subjects. In trials in which the subject discriminated between two calls with different nominal mean pulse rates, possible levels are “standard” (= nominal mean pulse rate of 0 SD from the population mean) or “alternative”. In trials in which the subject discriminated between two calls with the same nominal mean pulse rates (0 vs 0 SD from the population mean), the calls were randomly and arbitrarily labeled, and the possible levels are A or B.
Levels: 
standard, alternative, A, B

E. Standard.Speaker
Description: The number of the speaker that played the “standard” (or “A”) call. This was randomized between subjects.
Levels: 1 and 2

F. Ambient.Noise.File
Description: The number of the randomly generated chorus noise file used for playback of ambient noise in the trial. Because noise is a random realization, we replicated the noises played back and limited the number of subjects assigned to the same noise file. This variable counts up from 1 to 62.

G. Num.Complete
Description: The number of tests that the subject completed, between 1 and 16. Most subjects completed the full complement of tests (12 in the “experimental” group or 16 in the “control” group). 

H. Finished.All.Tests
Description: A binary value describing whether or not the subject completed the full complement of tests. This value is 1 if the value in column I is equal to the maximum number of tests assigned to that female and 0 otherwise.

I. Ambient.Noise.Level
Description: The level of ambient noise (also called “chorus shaped noise”) as a factor.
Levels: “none” (= quiet), “low” (60 dB), “mean” (70 dB), “high” (80 dB)

J: Nominal.Alternative.Mean
Description: The nominal mean pulse rate of the alternative stimulus measured in calls per minute.
Levels: 35.6, 40.0, 44.4, 48.8

K: Alt.in.SD
Description: The nominal mean pulse rate of the alternative stimulus measured in standard deviations from the population mean.
Levels: -3, -2, -1, 0

L: Choice
Description: The outcome of the phonotaxis trial as a word describing the female’s choice. In trials in which female discriminated between two alternatives with different nominal mean pulse rates, the possible values are “standard” and “alternative”. In trials in which females discriminated between two alternatives with equivalent nominal mean pulse rates, the possible values are “A” and “B”.

M: Choice.Binary
Description: The outcome of the phonotaxis trial as a binary (0 or 1) value. In trials in which the female discriminated between two alternatives with different nominal mean pulse rates, a choice for the alternative is coded as 1, whereas a choice of the standard is coded as 0. In trials in which females discriminated between two alternatives with equivalent nominal mean pulse rates, a choice of the B stimulus is coded as 1, whereas a choice of the A stimulus is coded as 0.

N: Latency
Description: The subject’s response latency in seconds, with a maximum value of 300.

O: Num.Alt.Calls.Experienced
Description: This variable describes the number of calls in the alternative stimulus that were played during the trial, and thus, also the number of calls from the stimulus that were used to calculate the realized mean pulse rate and realized CVw.

P: Realized.Alternative.Mean
Description: The realized mean pulse rate of the alternative stimulus. When the stimulus was perfectly consistent, this value will be the same as in column J; otherwise, it will differ.

Q: Realized.Alternative.SD
Description: The standard deviation of the pulse rate of the alternative stimulus. Calculated in order to determine the realized CVw.

R: Realized.Alternative.CVw
Description: The realized coefficient of variation within (CVw) the alternative stimulus. Perfectly consistent signals have a CVw of 0.

S: Num.Std.Calls.Experienced
Description: This variable describes the number of calls in the standard stimulus that were played during the trial, and thus, also the number of calls from the stimulus that were used to calculate the realized mean pulse rate and realized CVw.

T: Realized.Standard.Mean
Description: The realized mean pulse rate of the standard stimulus.

U: Realized.Standard.SD
Description: The standard deviation of the pulse rate of the standard stimulus. Calculated in order to determine the realized CVw.

V: Realized.Standard.CVw
Description: The realized coefficient of variation within (CVw) the alternative stimulus. Perfectly consistent signals have a CVw of 0.

W: Alt.Std.Difference.CVw
Description: The difference in CVw between the alternative and standard stimuli, calculated by subtracting the standard CVw from the alternative CVw.

X: LowerTraitValue
Description: The realized pulse rate of whichever of the “standard” or “alternative” signals in a given test had the lower pulse rate.

Y: PChoseFaster
Description: A binary value describing the probability that a female chose the stimulus with the faster pulse rate, based on the realized mean pulse rates of both alternatives. This value is 1 if the female chose the faster realized mean pulse rate and 0 if the female chose the slower realized mean pulse rate.
