The stimuli are movie clips inducing emotions. Ideally, if this measure allowed for quantification and integration with other physiological signals. I would ambrace any suggestion you have. The ideas I have already generated (some of them quite crazy) include the measurement of:
1. LEANING-FORWARD and LEANING-BACK by means of:
a) head accelerometry
b) motion capture
c) tracking the point of body balance, e.g. placing participants on a wii balance
d) recording a video of the posture and a software body movement tracking
2. EMG:
a) recording facial muscles related to fear and disgust (avoid) and pleasure or anger (approach)
3. SELF-REPORT:
a) participants use a rating dial to report their motivation continously
I am very curious what you think about these ideas and what other methods are available.
Lukasz, you might take a look at the following publication:
TREHUB, A. (1959). Ego disjunction and psychopathology. *Journal of Abnormal Psychology*.
It uses the Edwards Personal Preference Test to determine the degree of approach-avoidance conflict (ego disjunction).
Lukasz, all your ideas are good, save 1d which is not reliable because of the spatial and temporal resolution it has.

Hi, there are three behavioural reaction time measures that I'm aware of.
1. There is the Approach-avoidance Task (AAT). This task requires people to push or pull a joystick to simulate moving the stimuli closer or further away.
See: Rinck, M., & Becker, E. S. (2007). Approach and avoidance in fear of spiders. Journal of behavior therapy and experimental psychiatry, 38(2), 105-120.
2. There is the Selective Attention/Action Tendency Task (SA/ATT). This task requires people to touch stimuli on a touch screen to measure the speed that they will move their hand towards or away from a stimuli.
See: Sharbanee, J. M., Stritzke, W. G., Wiers, R. W., & MacLeod, C. (2013). Alcohol‐Related Biases in Selective Attention and Action Tendency Make Distinct Contributions to Dysregulated Drinking Behaviour. Addiction.
3. The stimulus-response compatibility task (SRC). This task requires participants to move a stick figure manikin towards or away from a stimulus.
See experiment 4: De Houwer, J., Crombez, G., Baeyens, F., & Hermans, D. (2001). On the generality of the affective Simon effect. Cognition & Emotion, 15(2), 189-206.
