# STIMULUS DEFINITION 
# The following file specifies all stimuli necessary for the simulation. This includes contexts, CSs and USs. The number
# of stimuli specified here controls the number of units and associations updated in each time step of the simulation,
# even if stimuli are never presented or used in the whole learning task. To minimize computing time, you should only specify
# stimuli that are actually necessary. You can comment stimuli out for a specific simulation by beginning their line with a hash (#).

# Each stimulus is specified in one line that consists of the following four entries that are separated by space: 

# (1) StimulusName. This can contain any alphabetic, numeric or special characters but no space

# (2) Minimal activation by the external sensory input 
# (3) Maximal activation by the external sensory input 
#     These values are used to determine the activation of the E and A units of the elements reprenting one stimulus by its sensory input
#     See the comments about the option "S_distribution" in parameter definition file for a more detailed explantion. 

# (4) Modality of the stimuli: 
#     Stimuli belonging to the same modality might activate each other’s I units. See the comments about the option
#     "norm_within_modality" in parameter definition file) for a more detailed explantion. Use integers to specify modality.
#     Stimuli with a modality of 0 do not inhibit each other, i.e. these stimuli have no specific modality as it might be
#     appropriate for US or context
