Shedding light on words and sentences: near-infrared spectroscopy in language research

Investigating the neuronal network underlying language processing may contribute to a better understanding of how the brain masters this complex cognitive function with surprising ease and how language is acquired at a fast pace in infancy. Modern neuroimaging methods permit to visualize the evolvement and the function of the language network. The present paper focuses on a specific methodology, functional near-infrared spectroscopy (fNIRS), providing an overview over studies on auditory language processing and acquisition. The methodology detects oxygenation changes elicited by functional activation of the cerebral cortex. The main advantages for research on auditory language processing and its development during infancy are an undemanding application, the lack of instrumental noise, and its potential to simultaneously register electrophysiological responses. Also it constitutes an innovative approach for studying developmental issues in infants and children. The review will focus on studies on word and sentence processing including research in infants and adults.     

Ambulante Psychotherapie der Substanzstörungen

Background

The revision of the psychotherapy guidelines in 2011 broadened the options for treating substance use disorders (SUD) in outpatient psychotherapy (OP).

Aim

The aims of this study were to answer the following questions: how frequently are SUDs treated in OP? What opinions do psychotherapists (PT) hold concerning the new treatment possibilities?

Material and methods

In this study the frequency of OP for patients with SUD, e.g. harmful use and abuse of as well as dependence on psychotropic substances according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) and the International Statistical Classification of Diseases and Related Health Problems (ICD-10), by private practice PTs as well as their attitude towards the treatment of patients with these diagnoses were investigated. Private practice PTs in five states in East Germany were asked to participate in a postal survey.

Results

Of the 1,382 PTs contacted, 229 (16.6 %) participated in the study. Of the respondents 94.3 % had treated at least one patient with SUD (4-week prevalence including nicotine dependence). These rates ranged from 3.1 % to 26.6 % depending on the substance and diagnosis (SUD as primary reason for treatment). The highest rates of strong affirmation for OP of approximately 20?% were found for disorders related to alcohol, tobacco and medication.

Conclusion

Most PTs treated at least one patient with SUD in OP. However, this particular type of treatment offer should be further extended. Information about the options of treating SUD in OP should be further disseminated and conducting such treatment should be supported by (e.g.) therapist training.     

Erziehungsfähigkeit in familienrechtlichen Begutachtungen

Parental competence describes the multidimensional ability of parents to take responsibility for their children and to bring them up. There is a multitude of criteria and guidelines for the assessment of parental competence in the context of family court procedures, when a child’s well-being is at risk or in the case of divorce and separation. However, little is known about what forensic experts in Germany understand by the term parental competence. In a nationwide study  600 forensic experts were questioned about the contents and their methods of assessment concerning parental competence. Of the 104 participating psychologists and doctors (response rate 17.3 %) 90 % follow a schema while assessing parental competence and include the factors interaction and communication skills, care and nurturing, relationship skills, attachment capabilities, teaching rules and complying with them, and the ability to foster a child. While 99 % conduct a talk with the mother, 98 % conduct at least one talk with the father; 27 % talk to both parents together, 94% talk to the child systematically, 84 % use free play and 78 % combine playing and talking. The most frequently mentioned third persons include social workers, new partners, nursery school teachers and child protective services. Approximately 77 % use standardized tests. Although the study revealed a large heterogeneity in the procedures used by forensic experts, there is more accordance concerning the understanding of the term parental competence and the assessment procedure. Possibilities to assess parental competence in more general and standardized terms are discussed.     

Brain potentials during language production in children and adults: An ERP study of the English past tense

The current study examines the neural correlates of 8-to-12-year-old children and adults producing inflected word forms, specifically regular vs. irregular past-tense forms in English, using a silent production paradigm. ERPs were time-locked to a visual cue for silent production of either a regular or irregular past-tense form or a 3rd person singular present tense form of a given verb (e.g., walked/sang vs. walks/sings). Subsequently, another visual stimulus cued participants for an overt vocalization of their response. ERP results for the adult group revealed a negativity 300–450 ms after the silent-production cue for regular compared to irregular past-tense forms. There was no difference in the present form condition. Children’s brain potentials revealed developmental changes, with the older children demonstrating more adult-like ERP responses than the younger ones. We interpret the observed ERP responses as reflecting combinatorial processing involved in regular (but not irregular) past-tense formation.
