In both conditions, about 40\% of the children acquired effective tool use by individual learning, and 90\% of the other children learned this by observing only one demonstration. When confronted with a changed situation (i.e., previous opening covered, alternative opening uncovered), children perseverated with the recently learned, but now ineffective tool use strategy. Neither age nor acquisition type of the first strategy affected preschoolers' perseverations. Results indicate that prior tool use experiences have differential effects in situations that require either transferring known functions to novel objects or using a familiar tool for an alternative purpose.}, language = {en} } @article{SchellhasGrundmannEdelstein2012, author = {Schellhas, Bernd and Grundmann, Matthias and Edelstein, Wolfgang}, title = {Control beliefs and school achievement in the context of family socialization results of a longitudinal study}, series = {Psychologie in Erziehung und Unterricht : Zeitschrift f{\"u}r Forschung und Praxis}, volume = {59}, journal = {Psychologie in Erziehung und Unterricht : Zeitschrift f{\"u}r Forschung und Praxis}, number = {2}, publisher = {Reinhardt}, address = {M{\"u}nchen}, issn = {0342-183X}, pages = {93 -- 108}, year = {2012}, abstract = {In a longitudinal sample of Icelandic children (7.9-12-15 years; n=109) the developmental relations between of control beliefs (locus of control) and school achievement were examined on the background of child rearing practices, socialization conditions, and social class from childhood to adolescence. Results show that supportive and restrictive socialization conditions in social classes affect school achievement as well as the development of control beliefs. Supportive child rearing practices in upper class families encourage the development of internal control beliefs in adolescence, and are coincident with higher school achievement. On the other hand, restrictive child rearing practices appear independent of social class and generally hinder the development of internal control beliefs and positive school achievement. Results of a path model suggest a lagged relationship between school achievement and control beliefs. School achievement in childhood (ages 7 and 9) predicts internal control beliefs in adolescence.}, language = {de} } @article{SchellhasHofmannGrundmannetal.1994, author = {Schellhas, Bernd and Hofmann, V. and Grundmann, Matthias and Edelstein, Wolfgang}, title = {Familiale Bedingungen von {\"A}ngstlichkeit und Depression und ihr Einfluß auf die kognitive Entwicklung}, year = {1994}, language = {de} } @article{SchellhasHofmannGrundmannetal.1995, author = {Schellhas, Bernd and Hofmann, V. and Grundmann, Matthias and Edelstein, Wolfgang}, title = {Developmental dynamics : a longitudinal study of anxiety}, year = {1995}, language = {en} } @article{HofmannSchellhasGrundmannetal.1995, author = {Hofmann, V. and Schellhas, Bernd and Grundmann, Matthias and Edelstein, Wolfgang}, title = {Developmental dynamics : stability, antecedents and consequences of depressive reactions}, year = {1995}, language = {en} } @article{GrundmannEdelsteinHofmannetal.1995, author = {Grundmann, Matthias and Edelstein, Wolfgang and Hofmann, V. and Schellhas, Bernd}, title = {The effect of non-normative childhood experiences on the emergence of risk factors in the development of the child}, year = {1995}, language = {en} } @article{Schellhas1995, author = {Schellhas, Bernd}, title = {Zur Stabilit{\"a}t von {\"A}ngstlichkeit}, year = {1995}, language = {de} } @article{ArteltBlissBrensteinetal.1995, author = {Artelt, Cordula and Bliß, Friederike and Brenstein, Elke and Burrmann, Ulrike and Lompscher, Joachim and Schellhas, Bernd}, title = {Bericht {\"u}ber die 6.
