This study provided a detailed investigation of perceived difficulty (PD) in a Fitts task. The Fitts task has been used to study Fitts's law, which shows that movement time (MT) is related to the information constraints of the movement (Fitts's Index of Difficulty, ID) such that there is a positive, linear relationship between MT and ID and MTs are similar when the scale of the movement requirements vary but ID is equal (scale invariance). According to Fitts's law, Fitts's ID provides an index of objective difficulty does Fitts's ID also provide an index of subjective difficulty? The main goal of …

Every day we are confronted with risky decisions in which the rewards and the punishments are not always clear. We like to believe that logic is the primary force behind our decisions, but in reality, emotion plays a very important role. This study examines the impact of participants' Behavioral Activation System (BAS) and Behavioral Inhibition System (BIS) on dynamic inconsistencies in a sequential gambling task. Contrary to the hypotheses, neither system predicted deviations following a win or and a loss. However, participants high in BAS were more likely to make negative deviations
