Fear and safety chemical cue data

Experiment where crayfish were exposed to two different types of odors (predatory odor from bass and alarm odor from detached claws) and allowed to explore an arena with a safety gradient. The safety gradient was constructed by different shelters and a fear gradient was made from different concentrations of the alarm odor.

Variables
Trial_Number
  • Label: Trial_Number
  • Definition: This is the number indicating the animal that was run. Each animal is run in a single trial, but in two fifteen minute segments. The first is exploratory and the second is with odor. A indicates an alarm odor and B is the bass odor
  • Type: Nominal
  • Missing values: None specified
Phase
  • Label: Phase
  • Definition: the treatment consists of two conditions: Odor and exploratory. The exploratory phase is run first which is followed by the introduction of odor.
  • Type: Nominal
  • Missing values: None specified
Odor
  • Label: Odor
  • Definition: The odor consists of two treatments, bass that have been fed crayfish or alarm odor which is made by macerating crayfish
  • Type: Nominal
  • Missing values: None specified
COM_Fear_pixel
  • Label: COM_Fear_pixel
  • Definition: COM means the center of mass which is the average location for the animal over the whole trial. The Fear location is the average X component. Fear increases as x increases

  • Type: Nominal
  • Missing values: None specified
COM_Safety_pixel
  • Label: COM_Safety_pixel
  • Definition: COM means the center of mass which is the average location for the animal over the whole trial. The Safety location is the average y component. Safety increases as y increases
  • Type: Nominal
  • Missing values: None specified
COM_Safety_Variance_pixel
  • Label: COM_Safety_Variance_pixel
  • Definition: This is the variance for the center of mass along the y axis
  • Type: Nominal
  • Missing values: None specified
Time_Walking_s
  • Label: Time_Walking_s
  • Definition: This is the time in seconds that the crayfish had a movement speed above 0.5 cm/s. This number is set as the lower level cut off.

Time_fear_1_s
  • Label: Time_fear_1_s
  • Definition: The testing arean is divided into a 16 square grid pattern that is 4 x 4. The four squares along the x axis represent increasing volumes of stimuli with 4 being the largest volume and 1 being the smallest volume. This is the fear axis and the variable here represents duration or time spent in this part of the arena (regardless of the y location) in seconds. It is a cumulative total over the whole trial.
