Beta Regression on Causal Ratings Predicted by Experimental Factors and WMC.

The dummy variable C2 was coded 1 for the zero contingency condition, -1 for the positive condition and 0 for the negative condition. C3 was coded 1 for the negative contingency condition, -1 for the positive condition and 0 for the zero condition. Ambiguity was coded 1 for the AU condition and -1 for the unambiguous conditions. Cognitive Demand was coded 1 for the high cognitive demand condition and -1 for the low conditions.

Beta Regression on Causal Ratings Predicted by Experimental Factors and WMC.

虚拟变量（dummy variable）C2的编码规则为：零因果依存条件组编码为1，正因果依存条件组编码为-1，负因果依存条件组编码为0。虚拟变量C3的编码规则为：负因果依存条件组编码为1，正因果依存条件组编码为-1，零因果依存条件组编码为0。歧义性（Ambiguity）的编码规则为：AU条件组编码为1，无歧义条件组编码为-1。认知需求（Cognitive Demand）的编码规则为：高认知需求条件组编码为1，低认知需求条件组编码为-1。
