Extraneous variables: These are variables that might affect the relationships between the independent variable and the dependent variable; experimenters usually try to identify and control for these variables. Confounding variables: When an extraneous variable cannot be controlled for in an experiment, it ...

Similarly, discrimination performance at the variable reach target (Reach Var ; d = 1.50) was significantly improved (p < 0.01). However, when participants consistently reached towards the same location (Reach Fix ), discrimination performance was the same as at non-target locations (P...
The ω2 is an estimate of the proportion of variance in the dependent variable accounted for by the independent variable. ω2-values greater than 0.14 indicate large effects, values between 0.06 and 0.14 suggest medium sized effects, and values between 0.01 and 0.06 are considered small effects4...
