“…This sort of understanding is directly related to ambivalent feelings (e.g., being both angry at and still loving toward one's parent). Development of this understanding proceeds from lack of acknowledgement of multiple emotions in younger children, 4 to acknowledgement and than to a greater understanding, involving an appreciation of variables, such as emotion valence (e.g., multiple positive emotions easier to understand than one negative and one positive), emotion intensity (e.g., one very strong and one very weak emotion easier to understand than two strong ones), and emotion target (e.g., multiple emotions toward acquaintance person easier than multiple emotions toward parent; see, e.g., Carroll & Steward, 1984;Donaldson & Westerman, 1986;Harter & Buddin, 1987;MeerumTerwogt, Koops, Oosterhoff, & Olthof, 1986;Reissland, 1985;Wintre & Vallance, 1994). This understanding appears to be mediated in part by an understanding that internal factors (e.g., beliefs and goals) have an impact on emotions (Donaldson & Westerman, 1986).…”
