Increases in language lateralization in normal children as observed using magnetoencephalography

Previous functional magnetic resonance imaging (fMRI) studies investigating hemispheric dominance for language have shown that hemispheric specialization increases with age. We employed magnetoencephalography (MEG) to investigate these effects as a function of normal development. In sum, 22 healthy children aged 7-16 years were investigated using two language tasks: a verb-generation (VG) task and a vowel-identification (VI) task. Significant hemispheric differences were found for both tasks in cerebral language areas using oscillatory MEG spectral analyses, confirming the MEG's ability to detect hemispheric specialization for language in children. Additionally, a significant increase of this lateralization as a function of age was observed for both tasks. As performance in the VI task showed no correlation with age, this increase seems to be unrelated to performance. These results confirm an increase in hemispheric specialization as a function of normal brain maturation.     

Modular Treatment for Children and Adolescents With Problematic School Absenteeism: Development and Description of a Program in Germany

Problematic school absenteeism is defined as absence from school occurring with a clinical-level mental disorder. It represents a higher-order term for school refusal, school truancy, and the combination thereof and is associated with an increased risk for school dropout, prolonged mental disorders, and unemployment. This article describes the manualized modular treatment of problematic school absenteeism (MT) by a multiprofessional team. The manual was developed to target a broad spectrum of mental disorders characterized by internalizing but also externalizing behavior. The therapeutic focus is on the reintegration into school and on the cognitive behavioral treatment of the mental disorder. The MT is based on a multilevel model of problematic school absenteeism. The treatment is informed by an extensive case-conceptualization and addresses motivational aspects by offering a low-threshold therapeutic design and motivational interviewing. Core interventions are represented in four modules: cognitive behavioral therapy, family counseling, school counseling, and a psychoeducational physical exercise program. A case vignette provides an illustration of the treatment and the specific graduated approach for school reintegration. The current modular approach is discussed in relation to other cognitive-behavioral manuals targeting a broad spectrum of mental disorders or school refusal.     

Hormonal and monoamine signaling during reinforcement of hippocampal long-term potentiation and memory retrieval

Recently it was shown that holeboard training can reinforce, i.e., transform early-LTP into late-LTP in the dentate gyrus during the initial formation of a long-term spatial reference memory in rats. The consolidation of LTP as well as of the reference memory was dependent on protein synthesis. We have now investigated the transmitter systems involved in this reinforcement and found that LTP-consolidation and memory retrieval were dependent on β-adrenergic, dopaminergic, and mineralocorticoid receptor (MR) activation, whereas glucocorticoid receptors (GRs) were not involved. Blockade of the β-adrenergic signaling pathway significantly increased the number of reference memory errors compared with MR and dopamine receptor inhibition. In addition, β-adrenergic blockade impaired the working memory. Therefore, we suggest that β-adrenergic receptor activation is the main signaling system required for the retrieval of spatial memory. In addition, other modulatory interactions such as dopaminergic as well as MR systems are involved. This result points to specific roles of different modulatory systems during the retrieval of specific components of spatial memory. The data provide evidence for similar integrative interactions between different signaling systems during cellular memory processes.     

Decomposing person and occasion-specific effects: an extension of latent state-trait (LSI) theory to hierarchical LST models

An extension of latent state-trait (LST) theory to hierarchical LST models is presented. In hierarchical LST models, the covariances between 2 or more latent traits are explained by a general 3rd-order factor, and the covariances between latent state residuals pertaining to different traits measured on the same measurement occasion are explained by 2nd-order latent occasion-specific factors. Analogous to recent developments in multitrait-multimethod methodology, all factors are interpreted in relation to factors taken as comparison standards. An empirical example from test anxiety research illustrates how estimates of additive variance components due to general trait, specific trait, occasion, state residual, method, and measurement error can be obtained using confirmatory factor analysis. Advantages and limitations of these models are discussed.     

Love: an important dimension in marital research and therapy

How do men and women describe and assess their relationship? What themes are decisive for its quality and stability? To answer such questions, we investigated a random sample of 204 married couples (reference sample), and 31 married couples undergoing psychotherapy (clinical sample) using a newly developed questionnaire. The participating couples were asked to evaluate a total of 19 themes with respect to their importance for the couple's connectedness. Although only rarely directly addressed in couple therapy and in‐vestigated in couple research, the theme “Love” proved to be the decisive factor for quality and stability. The results of the present study, therefore, indicate that “Love” should be investigated more thoroughly in couple research and included more actively in diagnostic and therapeutic procedures.     

Processes of task-set reconfiguration: switching operations and implementation operations

When participants are asked to shift between four dimensionally organized tasks which differ in the type of judgment (numerical vs. spatial) and/or the judgment-to-response mapping (compatible vs. incompatible), a characteristic profile of shift costs can be observed. It can be accounted for in terms of two different types of operations: generalizing switching operations on a dimensionally organized set of task representations and implementation operations [T. Kleinsorge, H. Heuer, Psycholog. Res. 62 (1999) 300]. In a first experiment we corroborated our previous findings by way of a new procedure that makes it possible to estimate shift costs unconfounded by a number of factors that are likely to affect estimates of shift costs based on more conventional procedures. In a second experiment we investigated the endogenous and exogenous nature of the postulated types of operations. The characteristic profile of shift costs disappeared when long precue intervals (PCIs) were used. Augmented by a formal analysis, this finding suggests that both switching and implementation operations are endogenously controlled. In addition, there remained some residual shift costs which were essentially insensitive to the nature of the task shift but depended on the difficulty of the new task. Most likely they reflect a process of consolidation of an already configured task set.

Emotionally Focused Family Therapy and Play Therapy Techniques

Emotionally Focused Family Therapy provides a framework for understanding children's behaviors in terms of attachment needs of comfort and support. However, when working with young children, play therapy is often developmentally preferred over “talk therapy.” By integrating play therapy techniques within an Emotionally Focused Family Therapy theoretical framework, therapists can help parents understand and meet their child's needs for affection and comfort. This article will discuss how play therapy techniques can be integrated with an Emotionally Focused Family Therapy theoretical framework for work with young children and their families.
