HyGene parameters, definitions, boundary values, and values used in the simulation.

Parameter	Definition	Boundaries	Values used in simulation
L	Quality of memory encoding: the probability that each feature in the experienced event is encoded into the corresponding memory trace vector.	0 ≤ L ≤ 1	L = 0.5
			L = 0.6
			L = 0.7
			L = 0.8
			L = 0.9
TMAX	A retrieval parameter that determines how long the model searches semantic memory. Generation terminates when the total number of retrieval failures (the model fails to retrieve a novel hypothesis) exceeds TMAX TMAX can be used to model task characteristics such as time pressure, and individual variables such as effort or motivation.	TMAX ≥ 0	TMAX = 10
Ac	The activation criterion for memory traces in episodic memory. Episodic traces are placed in the activated subset if their activation exceeds this threshold, Ac.	0 ≤ Ac ≤ 1	Ac = 0.166
ɸ	This working memory capacity parameter specifies the upper limit of how many hypotheses can be held in working memory.	ɸ ≥ 0	ɸ = 2 (low working memory capacity) ɸ = 4 (high workingmemory capacity)
ActMinH	The activation criterion for hypotheses to be placed in working memory. ActMinH is always set to 0 initially, and then is dynamically updated based on the activation values of hypotheses in the SOC.	ActMinH ≥ 0	ActMinH = 0 (to start)
