Perform free recall typed responses.
Parameters
----------
lbl : Label state
The text that will appear on the screen to indicate to the
participant that they are to type a response. This text
will disappear from the screen when a response is
begun and return when ready for the next response. It's a
good idea to use something like a label with '???????'.
max_duration : {10.0, float}
The amount of time in seconds that the participant is given
to respond.
max_resp : {100, int}
Maximum number of responses that the participant is allowed
to enter.
base_time : float
Manually set a time reference for the start of the state. This
will be used to calculate reaction times.
Example
--------
FreeKey(Label('???????'), max_duration=15.0)
The message '??????' will appear on the screen,
and participants will be given 15 seconds to enter a response,
replacing that text. They can enter as many responses as possible
in the 15 second time period.
Log Parameters
---------------
All parameters above and below are available to be accessed and
manipulated within the experiment code, and will be automatically
recorded in the state.yaml and state.csv files. Refer to State class
docstring for additional logged parameters.
responses : list
List of typed responses, each with the following information:
first_key_time, first_key_rt, enter_key_time, enter_key_rt,
response, response_num.
The time is the actual time, the rt is the time since the
base_time.
