The present experiment investigated the effect of a music program on phonological awareness in preschoolers. In particular, the effects of a music program and a phonological skills program on phonological awareness were compared. If language and music share basic processing mechanisms, the effect of both programs on enhancing phonological awareness should be similar. Forty-one preschoolers (22 boys) were randomly assigned to a phonological skills program, a music program, and a control group that received sports training (from which no effect was expected). Preschoolers were trained for 10 min on a daily basis over a period of 20 weeks. In a pretest, no differences were found between the three groups in regard to age, gender, intelligence, socioeconomic status, and phonological awareness. Children in the phonological skills group and the music group showed significant increases in phonological awareness from pre- to post-test. The children in the sports group did not show a significant increase from pre- to post-test. The enhancement of phonological awareness was basically driven by positive effects of the music program and the phonological skills program on phonological awareness for large phonological units. The data suggests that phonological awareness can be trained with a phonological skills program as well as a music program. These results can be interpreted as evidence of a shared sound category learning mechanism for language and music at preschool age.

the present study investigated whether the association between music lessons and intelligence is mediated by executive functions. Intelligence and five different executive functions (set shifting, selective attention, planning, inhibition, and fluency) were assessed in 9- to 12-year-old children with varying amounts of music lessons. Significant associations emerged between music lessons and all of the measures of executive function. Executive functions mediated the association between music lessons and intelligence, with the measures of selective attention and inhibition being the strongest contributors to the mediation effect. Our results suggest that at least part of the association between music lessons and intelligence is explained by the positive influence music lessons have on executive functions, which in turn improve performance on intelligence tests.

The present experiment examined the degree to which analytic and holistic modes of processing play a role in the way children and adults categorize upright and inverted faces. Seven-year-old children (n = 38), 10-year-old children (n = 40), and adults (n = 55) were instructed to classify upright and inverted faces into two categories. The construction of the categories allowed participants to categorize the faces either analytically (by focusing on a single attribute) or holistically (in terms of overall similarity). The results show both a developmental trend from analytic to holistic processing and an effect of face inversion with increasing age. Thus, it appears that 7-year-old children process upright and inverted faces in a way comparable to their processing of nonfacial visual stimuli, namely analytically, whereas a growing proportion of 10-year-olds and adults process only upright faces holistically by adopting a specific mode of face processing.

Emotional valence is predominately conveyed in social interactions by words and facial expressions. The existence of broad biases which favor more efficient processing of positive or negative emotions is still a controversial matter. While so far this question has been investigated separately for each modality, in this narrative review of the literature we focus on valence effects in processing both words and facial expressions. In order to identify the factors underlying positivity and negativity effects, and to uncover whether these effects depend on modality and age, we present and analyze three representative overviews of the literature concerning valence effects in word processing, face processing, and combinations of word and face processing. Our analysis of word processing studies points to a positivity bias or a balanced processing of positive and negative words, whereas the analysis of face processing studies showed the existence of separate positivity and negativity biases depending on the experimental paradigm. The mixed results seem to be a product of the different methods and types of stimuli being used. Interestingly, we found that children exhibit a clear positivity advantage for both word and face processing, indicating similar processing biases in both modalities. Over the course of development, the initial positivity advantage gradually disappears, and in some face processing studies even reverses into a negativity bias. We therefore conclude that there is a need for future research that systematically analyses the impact of age and modality on the emergence of these valence effects. Finally, we discuss possible explanations for the presence of the early positivity advantage and its subsequent decrease.

The development of self-regulation has been studied primarily in Western middle-class contexts and has, therefore, neglected what is known about culturally varying self-concepts and socialization strategies. The research reported here compared the self-regulatory competencies of German middle-class (N = 125) and rural Cameroonian Nso preschoolers (N = 76) using the Marshmallow test (Mischel, 2014). Study 1 revealed that 4-year-old Nso children showed better delay-of-gratification performance than their German peers. Study 2 revealed that culture-specific maternal socialization goals and interaction behaviors were related to delay-of-gratification performance. Nso mothers' focus on hierarchical relational socialization goals and responsive control seems to support children's delay-of-gratification performance more than German middle-class mothers' emphasis on psychological autonomous socialization goals and sensitive, child-centered parenting.
