Association Learning with Own‐ and Other‐race Faces in three‐ and six‐month old infants – A longitudinal study

This longitudinal study assessed 133 Caucasian German infants at 3 and 6 months of age to investigate the influence of own‐race and other‐race faces as visual stimuli on association learning in the visual expectation paradigm (VExP). The study is related to the findings on the other‐race‐effect (ORE) which is said to emerge at 6 months of age. Caucasian faces were used as stimuli of a familiar ethnic category, whereas African faces were used as stimuli of an unfamiliar ethnic category. There was no significant difference between the two stimulus classes in infants' reaction time (RT) to stimulus shifts at 3 months. At 6 months of age, infants' RT decreased significantly in the Caucasian faces condition but not in the African faces condition. These results indicate that the processing of other‐race versus own‐race faces by the age of 6 months, which is also the relevant age for the onset of the ORE, has an important influence on the performance on the VExP.

Infant Contingency Learning in Different Cultural Contexts

Three‐month‐old Cameroonian Nso farmer and German middle‐class infants were compared regarding learning and retention in a computerized mobile task. Infants achieving a preset learning criterion during reinforcement were tested for immediate and long‐term retention measured in terms of an increased response rate after reinforcement and after a 24‐h delay compared with baseline. It was hypothesized that infants from both cultural communities would acquire the contingency between own motion and mobile movement, as they similarly experience contingent responses in social interactions. Nso infants were assumed to show a higher learning rate related to their advanced gross motor development, whereas German infants were expected to show a higher baseline because of culture‐typical motor handling promoting a high level of activity (i.e. lying supine). Results showed immediate and long‐term retention in infants from both cultural contexts, as well as a higher baseline for German infants. Although the learning rate was higher for Cameroonian infants, logistic regression revealed that learning was not related to gross motor development but depended on the level of baseline response. Thus, contingency learning was shown in different cultural environments, and the level of baseline activity coined by culture‐specific motor handling turned out to influence learning within the mobile task.

Results of nuclear medical, electroencephalographic, and angiographic examinations after brain tumor operations]

The methods of nuclear medicine and electro-encephalography allow, in combination, in almost every case the answer to the question of the cerebral tumour relapse. Our evaluation confirms the discovery of the greater sensitivity of the isotopic methods with relapses of glioblastomas, while relapses of meningiomas, astrocytomas, oligodendrogliomas and spongioblastomas can be recognized more frequently only by electro-encephalographic methods. The value of angiography is limited in cases of cerebral tumour relapses without pathological vascularisation, since the swelling can spread in the resection cavity without retroaction on the surrounding areas. For this reason vascular displacement (an only be observed very late on. Clinical judgement is furthermore complicated by the fact that after the removal of the primary tumour, often no reposition of the arteries ensues. After our exainations, a negative angiographic condition can be rule out a diagnosis of a relapse which has been established by electro-encephaolographic and isotopic methods.

A randomized pilot trial comparing videoconference versus face-to-face delivery of behavior therapy for childhood tic disorders

Comprehensive Behavioral Intervention for Tics (CBIT) has been shown to be effective for reducing tics in children with chronic tic disorder. Unfortunately, there remain significant barriers to dissemination. The aim of the current study was to examine the effectiveness of CBIT delivered over videoconference. Twenty children were randomly assigned to receive CBIT over videoconference or via traditional face-to-face delivery. Results show that both treatment delivery modalities resulted in significant tic reduction with no between group differences. Furthermore, acceptability and therapist-client alliance ratings were strong for both groups. Together, these results suggest that videoconference is a viable option for disseminating CBIT.
