This page provides miscellaneous materials regarding research currently conducted in the laboratory.
Impulsivity (funded by NIDA)
Video game clip of opposition task in CIRP - M+P- condition (youtube)
Example of opposition task as implemented in the continuous impulsivity and risk platform (CIRP). The first two orcs involved a power value of 1.25 whereas the second two involved a power of 0.60.
Video game clip of escalating interest task - magnitude (youtube)
Basic escalating interest task clip showing increasing magnitude. This is a short clip showing a power of 1.0 (linear) increase in damage magnitude after a shot is taken.
Video game clip of escalating interest task - probability (youtube) - be sure to turn your audio up
This clip shows selected scenes from our preparation examining the study of impulsivity. The blue bar in the lower left corner indicates how much damage will be done (for magnitude manipulations) or the probability of the weapon working (for probability manipulations) when the player pulls the trigger. These scenes are for a probability manipulation in which we occasionally change the shape of the mathematical function that defines the way in which the weapon recharges (the first scene is power = 1.0, the second is power = 1.5, the third is power = 0.5). For more details, see Young, Webb, & Jacobs (2011).
Video game clip of delay discounting task - magnitude (youtube)
Delay discounting task clip showing increasing magnitude. This is a short clip of an increase in damage magnitude after a shot is taken. Note that the damage goes to zero after two seconds indicating a commitment to the larger later amount.
Causal Decision Making (funded by AFOSR and NSF)
Video game clip of basic causal task (youtube)
This is a clip showing a participant approaching a trio of potential targets, observing their behavior, and firing at the chosen target. The target's weapon has a delay thus making the decision particulary difficult. The latter part of the video shows a bird's-eye-view of the game region for one of the levels. See Young & Nguyen (2009); Nguyen et al. (2010); Young et al. (2011a; 2011b)
Video game clip of continuous causality (youtube) - be sure to turn your audio up
This clip shows a demonstration of our preparation to study continuous causation in which the proximity of the "enemy" to an "enemy detector" (the pole) changes the pitch or sets off (depending on the condition) the detector. Young & Cole (in press).
Example stimuli from Young and Racey (2009, Empirical Studies of the Arts), color versions:
The following are examples of basic causal interactions that we are studying in the lab. We are exploring a number of variations on this theme.
Two examples from the original study (Young, Rogers, & Beckmann, 2005):
Training movies used with pigeon study (Young, Beckmann, & Wasserman, 2006):
Color change as a method of bridging temporal gaps (Young & Falmier, AJP, 2008):
The effect of animacy on causal judgments (Falmier & Young, 2008):
The effect of gap fillers on judgment (Young & Falmier, QJEP, 2008):
Exp 1 of Spatial Gap study - gap fillers
Exp 2 of Spatial Gap study - line markers
