Cognitive diagnosis models are diagnostic models used to classify respondents into homogenous groups based on multiple categorical latent variables representing the measured cognitive attributes. This study aims to present longitudinal models for cognitive diagnosis modeling, which can be applied to repeated measurements in order to monitor…

To further investigate the possible regulatory role of private and inner speech in the context of referential social speech communications, a set of clear and systematically applied measures is needed. This study addresses this need by introducing a rigorous method for identifying private speech and certain sharply defined instances of inaudible…

This article demonstrates how a set of complementary qualitative methods can be used to construct a detailed picture not only of the nature of young people's representations of a distant place but the processes of learning by which such representations develop over the medium term. The analysis is based on an interpretive case study of a class of…

The development of language indicating the emergence of thinking about the thoughts of self and others has been scarcely studied in Spanish-speaking children. For this reason, we studied the development of mental state language and various indicators of language development in 25 Spanish-speaking children assessed at 3, 3 1/2, 4, 4 1/2, and 5…

Attempted empirical validation of the fixated-regressed typology used in child sexual abuse literature. Analysis of 136 consecutive cases of convicted child molesters over a 2-year period revealed that the victim's and offender's family relatedness and the offender's prior non-sex-criminal record significantly predicted an offender's degree of…

Background: The relationship between the age of reaching infant developmental milestones and later intellectual function within the normal population remains unresolved. We hypothesised that the age of learning to stand in infancy would be associated with adult executive function and that the association would be apparent throughout the range of…

Twelve papers on the emergence and maintenance of severe clinical depression and depressive symptoms during adolescence are presented.

This paper explores the relation between the communicative and categorical functions of language and the acquisition of language production. Three major factors in language acquisition are communication, ability for representation and the process of categorization. This paper offers evidence that a sudden and dramatic increase in lexical skill…

The longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…

For this study, the second in the cross sectional series, based on the Conceptual Learning and Development (CLD) model, assessment batteries were developed to determine each child's level of attainment and related use of the concepts "equilateral triangle,""cutting tool,""noun," and "tree." Batteries were…

For this study, the second in the cross sectional series, based on the Conceptual Learning and Development (CLD) model, assessment batteries were developed to determine each child's level of concept attainment and also the related use of the concepts "equilateral triangle,""cutting tool,""noun," and "tree."…
