Commentary: Rethinking the Development of "Nonbasic" Emotions: A Critical Review of Existing Theories.

Draghi-Lorenz et al. (2001), in their well-cited review article (104 times in Google Scholar and 37 times in Web of Science, as of 07 December 2015), outlined current theories of emotional development in infants. They summarized the arguments of a few well-known researchers in the field, describing both the theoretical approaches and the rationale behind those approaches. In the end, the authors argued against the mainstream chronology describing the emergence of so-called “nonbasic” emotions. According to their critical review, infants younger than 2 years old may have the capacity to experience these emotions.Draghi-Lorenz et al. first delineated those emotions widely considered “basic,” namely interest, disgust, joy, distress, anger, sadness, surprise, and fear. The nonbasic emotions are shame, embarrassment, coyness, shyness, guilt, jealousy, pride, contempt and so on. Then the researchers further explored the literature surrounding some of the nonbasic emotions, finding a surprising number of studies showing that infants as young as 2 months might be found to express these emotions (Guillaume, 1926; Buhler, 1930; Piaget, 1932; Hoffmann, 1984; Masciuch, 1988; Reissland, 1990; Trevarthen, 1992; Reddy, 2000). For example, Reddy (2000) found that 2–3 month-old infants showed “coy” smiling, which occurs simultaneously with gaze/head aversion and curving arm movement, and had been reported before only in 2-year-old toddlers earliest.Next, the review presented two contrasting emotional development theorists from two theoretical polarities: the Lewis (Lewis, 1987, 1993) and the Trevarthen (Trevarthen, 1979, 1984) theories. Fundamentally, Lewisu0027s framework may best be illustrated in the context of two basic and interconnected proposals: “The young infant is incapable of ‘nonbasic’ emotions because these depend on specific higher representational skill and this is so because until these skills emerge the infant cannot experience his/her own emotions nor those of others” (Draghi-Lorenz et al., 2001, p. 273).The key difference between Lewisu0027s and Trevarthenu0027s reasoning lies in Trevarthenu0027s belief that both nonbasic and basic emotions are independent from higher representational skills, which are developed only later in life. Furthermore, Trevarthen holds a nativist point of view on the matter of when interpersonal awareness is present (from birth, if not before). Draghi-Lorenz et al. (2001) argued specifically against those two concepts in the conclusion of their review. Instead, they suggested a theoretical construct that synthesizes emotion and representational skills and adopts a different perspective on interpersonal awareness. Conceivably, this approach could explain a great deal about the emergence of nonbasic emotions and account for the large discrepancies between theorists of early emotional development. The authors noted that most psychologists in the field believe that nonbasic emotions emerge when at the age of two. These psychologists assume that a conceptual representation of the self is necessary for the expression of such emotions as pride, guilt, jealousy, etc. and that the capacity for interpersonal awareness develops no sooner than 2 years after birth.Ultimately, Draghi-Lorenz et al. developed a theoretical frame of reference for early nonbasic emotions to assess the possibility of more complex emotions in infants younger than 2 years, while also giving a nod to theoretical and practical consequences. Importantly, the authors claimed, “interpersonal awareness should be understood as a continuous process rather than as an achievement at some point in time” (p. 296). Therefore, infantsu0027 acquisition of the capacity to express increasingly complex emotions should not be seen as a one-time accomplishment but rather as an on-going process starting early in life (possible before birth), finally ending late in adulthood (or possibly never). The authors agreed there is somewhat limited evidence supporting the possibility of early nonbasic emotions, but they elaborated on some other important points stemming from their critical review. They pointed out that it is feasible that infants are aware of others from a quite early age (by showing interest in human features such as face, human voice and movement) (Walker-Andrews, 1997) and that an infant also may have awareness of itself (e.g., Butterworth, 1989, 1995). In the end, Draghi-Lorenz et al. appropriately and importantly noted that paradigm change in the perception of how and when complex (i.e., nonbasic) emotions emerge highlights infants as agents with significantly more competency who are active participants in social interactions.The shortcomings of Draghi-Lorenz et al.u0027s review must be acknowledged. Most glaringly, the research presented in their article supporting the early emergence of nonbasic emotions is outdated. Few papers cited are from the Twenty-first century. Many papers represent research from the first half of the Twentieth century, with the earliest citation dating to 1892. In addition, the methodologies for acquiring and analyzing data have evolved dramatically since the middle of the last century. That is, future research in development of infantu0027s emotions could benefit from emotion coding software (e.g., Lewinski et al., 2014a), which can objectively code (based on objective datasets such as Olszanowski et al., 2015) large numbers of facial videos outperforming even human coders under certain circumstances (Lewinski, 2015a). Such software can help in saving substantial amount of coding time (Lewinski et al., 2014b; Lewinski, 2015b). Nonetheless, research after 2001 supports Draghi-Lorenz et al. conclusions. For example: (i) Colonnesi et al. (2013) replicated and extended Reddy (2000) findings to positive shyness; (ii) Hart and Carrington (2002) and Hart et al. (2004) provided new evidence on 6-month-old infants being jealous of motheru0027s attention; (iii) Draghi-Lorenz et al. (2005) found that 2-to-4-month-old infants “can be perceived as shy, coy, bashful or embarrassed” (p. 63).In conclusion, Draghi-Lorenz et al. were innovative in their review of and challenge to the status quo of procedures and knowledge in the realm of early childhood emotional development. Following the authorsu0027 line of reasoning, one may concur that the nonbasic emotions might be present in infants much younger than 2 years old. Nonetheless, without a doubt, more data could be collected that would support the opposite point of view. If a choice must be made, perhaps it is better to consider the infant as “competent neonate” rather than needy and “not-that-sophisticated” beings.
