ABSTRACT
The present multimethod longitudinal study aimed at investigating development and stability of implicit memory during infancy and early childhood. A total of 134 children were followed longitudinally from 3 months to 3 years of life assessing different age-appropriate measures of implicit memory. Results from structural equation modeling give further evidence that implicit memory is stable from 9 months of life on, with earlier performance predicting later performance. Second, it was found that implicit memory is present from early on, and no age-related improvements are found from 3 months on. Results are discussed with respect to the basic brain structures implicit memory builds on, as well as methodological issues.

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.

The other-race effect (ORE) implies the better recognition of faces of one's own race compared with faces of a different race. It demonstrates that face recognition is shaped by daily experience with human faces. Such experience mainly includes structural information of own-race faces and also information on the way faces are usually seen, as a whole or partly covered by scarves or other headwear. In two experiments, we investigated how this mode of presentation is related to the occurrence of the ORE during childhood. In Experiment 1, 4-year-old German children (N = 104), accustomed to seeing faces without headwear in daily life, were asked to recognize female Caucasian or African faces, presented either as a whole or wearing a woolen hat, in a forced choice paradigm. In Experiment 2, 4-year-olds from rural Cameroon (N = 70), accustomed to seeing faces with and without headwear in daily life, participated in the same task. In both groups, the ORE was present in the familiar mode of presentation, that is, in whole faces in German children and in whole and partly covered faces in Cameroonian children. The results are discussed in relation to the role of experience for face recognition processes.

This study aims to analyze culture-specific development of maternal interactional behavior longitudinally. Rural Cameroonian Nso mothers (n = 72) and German middle-class mothers (n = 106) were observed in free-play interactions with their 3- and 6-month-old infants. Results reveal the expected shift from a social to a nonsocial focus only in the German middle-class mothers' play interactions but not the rural Nso mothers' play. Nso mothers continue their proximal interactional style with a focus on body contact and body stimulation, whereas German middle-class mothers prefer a distal style of interaction with increasing object-centeredness. These cultural differences are in line with broader cultural models and become more accentuated as the infants grow older.

The authors explored priming in children from different cultural environments with the aim to provide further evidence for the robustness of the priming effect. Perceptual priming was assessed by a picture fragment completion task in 3-year-old German middle-class and Cameroonian Nso farmer children. As expected, 3-year-olds from both highly diverging cultural contexts under study showed a priming effect, and, moreover, the effect was of comparable size in both cultural contexts. Hence, the children profited similarly from priming, which was supported by the nonsignificant interaction between cultural background and identification performance as well as the analysis of absolute difference scores. However, a culture-specific difference regarding the level of picture identification was found in that German middle-class children identified target as well as control pictures with less perceptual information than children in the Nso sample. Explanations for the cross-cultural demonstration of the priming effect as well as for the culturally diverging levels on which priming occurs are discussed.

Recognizing individual faces is an important human ability that highly depends on experience. This is reflected in the so called other-race effect; adults are better at recognizing faces from their own ethnic group, while very young infants do not show this specialization yet. Two experiments examined whether 3-year-old children from two different cultural backgrounds show the other-race effect. In Experiment 1, German children (N = 41) were presented with a forced choice paradigm where they were asked to recognize female Caucasian or African faces. In Experiment 2, 3-year-olds from Cameroon (N = 66) participated in a similar task using the same stimulus material. In both cultures the other-race effect was present; children were better at recognizing individual faces from their own ethnic group. In addition, German children performed at a higher overall level of accuracy than Cameroonians. The results are discussed in relation to cultural aspects in particular.
