The contact hypothesis predicts that cooperative interaction with members of a disliked group results in increased liking for those members and generalizes to more positive attitudes toward the group.
50 Furthermore, subjects with a tendency for binge eating showed increased liking for all food categories.
Although the drug did not increase subjective liking for passively viewed food images, it increased liking for the high-calorie food images in the grip force task, suggesting a potential relationship between liking and wanting related to motivational processes.
Preference and exposure ratings were not influenced by socially desirable responding or socioeconomic status, although an increased liking for vegetables was associated with higher social class.
This process is called flavour-flavour learning, as an association is established between a new or neutral food and the liked sweet taste resulting in an increased liking for that food.
This habituation process is one possible mechanism behind the so-called "mere exposure" effect in which repeated exposures to a stimulus produce increased liking for it (Bornstein, 1989; Zajonc, 1968).
Preliminary analyses showed that exposure and preference ratings were not contaminated by socially desirable responding and only liking for vegetables was significantly related to socioeconomic status (IDACI score) (rs=−0.25, p=0.005) (higher social class associated with increased liking for vegetables).
Compared to the spoon-fed group, the baby-led group demonstrated (1) significantly increased liking for carbohydrates (no other differences in preference were found) and (2) carbohydrates to be their most preferred foods (compared to sweet foods for the spoon-fed group).
As a result, the parametric analysis of increased liking ratings for dance stimuli in the pretraining scan revealed regions within the AON mask most engaged when viewing the most aesthetically pleasing novel movements.
40 In this study, the left STG in particular emerges as the core region influenced by both sensorimotor experience and increased liking, when we control for pretraining activity.
Although previous research has shown that perceived objective similarity (Me-sharing) and perceived subjective similarity (I-sharing) both increase liking for strangers, perceived subjective similarity may have a unique effect on selflessness.
