LP1 Sensing a world state
If world state property W occurs of strength
V
then a sensor state for W of strength
V
will occur.
world_state(W, V)
→
sensor_state(W, V)
For the example scenario this dynamic property is used by the agent to observe both
the paper attached looking like a charge and the paper type looking like an offer; to
this end the variable
W
is instantiated by
charge
and
offer
. From the sensor states, sen-
sory representations are generated according to the dynamic property LP2. Note that
also here for the example the variable
W
is instantiated as indicated.
LP2 Generating a sensory representation for a sensed world state
If a sensor state for world state property W with level
V
occurs,
then a sensory representation for W with level
V
will occur.
sensor_state(W, V)
→
srs(W, V)
Next the dynamic property for the process for belief generation is described, where
both the sensory representation and the feeling play their role. This specifies part of
the loop between belief and feeling. The resulting level for the belief is calculated
based on a function
g(
β
,
V
1
, V
2
)
of the original levels.
LP3 Generating a belief state for a feeling and a sensory representation
If a sensory representation for w with level
V
1
occurs,
and the associated feeling of b with level
V
2
occurs
and the belief for w has level
V
3
and β
1
is the person's orientation for believing
and γ
1
is the person's flexibility for beliefs
then a belief for w with level
V
3
+ γ
1
(g(
β
1
, V
1
, V
2
)-V
3
)
Δ

will occur.
srs(w, V

) & feeling(b, V
2
) & belief(w, V

)
→
belief(w, V

γ

(g(

,V

For the function
g(
β
, V
1
, V
2
)
the following has been taken:
g(
β
, V
1
, V
2
)
=
β
(1-(1-V
1
)(1-V
2
)) + (1-
β
)V
1
V
2
Note that this formula describes a weighted sum of two cases. The most positive case
considers the two source values as strengthening each other, thereby staying under
1
:
combining the imperfection rates
1-V
1
and
1-V
2
of them provides a decreased rate of
imperfection expressed by:
1-(1-V
1
)(1-V
2
).
The most negative case considers the two
source values in a negative combination: combining the imperfections of them pro-
vides an increased imperfection. This is expressed by
V
1
V
2
. The factor
can be used
to model the characteristic of a person that expresses the person's orientation (from
0
as most negative to
1
as most positive).
Dynamic property
LP4
describes the emotional response to a belief in the form of
the preparation for a specific bodily reaction. This specifies part of the loop between
feeling and body state. This dynamic property uses the same combination model
based on
g(
β
β
, V
1
, V
2
)
as above.
LP4 From belief and feeling to preparation of a body state
If belief w with level
V
1
occurs
and feeling the associated body state b has level
V
2
and the preparation state for b has level
V
3
and
β
2
is the person's orientation for emotional response
and
γ
2
is the person's flexibility for bodily responses
then preparation state for body state b will occur with level
V
3
+ γ
