Figure 2. Results of the behavioral tasks for the NS (◻) and SS (◼) soft drinks and yoghurt dinks. (A) Choice: there was a main significant effect for sweetener type (p<0.05): the SS drinks were chosen more often than the NS drinks.

(B) Total (implicit) intake (g): there was a main significant effect of time (p<0.05): intake was greater after the conditioning period than before. (C) Explicit liking: there was a main significant effect of drink type (p<0.01): the yoghurt drinks were more explicitly liked than the soft drinks. There was a significant interaction between drink type and sweetener type: the SS soft drink was more liked than the NS soft drink (p<0.05). (D) Expected satiety: there was a significant main effect of drink type (p<0.0001): the yoghurts drinks were expected to be more satiating than the soft drinks. There was a significant interaction between drink type and time (p<0.01): after the conditioning period the soft drinks were rated as more satiating. Values are means ± SEMs (n=40). For the choice tasks chi-squared analyses were performed. All others were analyzed by means of ANOVA (mixed model procedure).
