This study aims at disentangling the causal effects of unemployment on physical and mental health from the selection of the unhealthy into unemployment. To identify causal effects, it explores hypotheses concerning how physical and mental health deterioration gain additional momentum with a longer duration of unemployment. In contrast, mere selection into unemployment implies time-constant effects of unemployment on physical and mental health.

The study explores the consequences of gender-selective internal migration for regional mating chances in Germany, comparing different cohorts as well as different types of regions. Indicators of the partner market based on time series of the official German regional population statistics are combined with indicators of migration and on regional economic, educational, and settlement structures. Instead of the simple sex ratio, which is the standard measure for partner market conditions in previous research, the study at hand uses the availability ratio suggested by Goldman et al.

Recent studies have suggested that sensory processing atypicalities may share genetic influences with autism spectrum disorder (ASD). To further investigate this, the adolescent/adult sensory profile (AASP) questionnaire was distributed to 85 parents of typically developing children (P-TD), 121 parents from simplex ASD families (SPX), and 54 parents from multiplex ASD families (MPX). After controlling for gender and presence of mental disorders, results showed that MPX parents significantly differed from P-TD parents in all four subscales of the AASP.

This paper explores the Partnermarktsurvey to analyze how the size and composition of individuals' friendship networks are associated with the opportunities for contact and interaction provided by individuals' immediate social environment. The size and composition of individuals' social environment are strongly reflected in the size and composition of their network of friends. Several properties of an individual's foci of activity help to transform mere contacts into opportunities for interaction.

Stimulus-Response Compatibility (SRC) refers to the fact that some tasks are performed easier and better than others because of the way stimuli and responses are paired with each other. To assess the brain responses to stimulus-response conflicts, we investigated the behavioral (accuracy and Reaction Times: RTs) as well as the physiological response (Lateralized Readiness Potentials: LRP) modulations in a positional blocked and a conditional mixed design in twelve university students. Results revealed that the performance was less accurate and the RTs, as well as the LRP onset, were delayed under the mixed conditional design.

In a passive auditory oddball study the development of novelty processing was examined in 5-7 (N=26), 8-9 (N=31), 10-12 (N=30), and 18-29 (N=35) years olds. Even though the main goal of this study was to replicate the findings of an earlier one, a shorter and simplified paradigm was used in order to gather developmental reference data for non-responsive patient groups that are unable to give an overt response. As expected, this adapted procedure replicated the findings regarding the development of passive novel sound processing.

The finding that relatives of individuals with autism show mild autistic traits is referred to as the broader autism phenotype (BAP). In the current study, 25 parents with a child with high-functioning autism and 25 parents with typically developed children were compared on: (1) the Block Design Test, (2) the Autism-Spectrum Quotient (AQ), and (3) a reaction time task to examine reflexive covert visual orienting to social (eyes) and non-social (arrows) cues. The parent groups were scored similar on the Block Design Test and the AQ.

Objective: The relative change in amplitude of the P50 component in response to the second click compared to the first one is commonly thought to index sensory gating. Despite numerous P50 gating studies, reports about its development are scarce. The present study examined the development and gender differences of P50 sensory gating.

Rett syndrome is a neurodevelopmental disorder that occurs almost exclusively in females. It is characterized by a progressive loss of intellectual functioning and motor skills, and the development of stereotypic hand movements, that occur after a period of normal development. Event-related potentials were recorded to a passive auditory- and visual oddball task in 17 females with Rett syndrome aged between 2 and 60 years, and age-matched controls.

The present study investigates visual orienting to directional cues (arrow or eyes) in adults with high functioning autism (n = 19) and age matched controls (n = 19). A choice reaction time paradigm is used in which eye- or arrow direction correctly (congruent) or incorrectly (incongruent) cues target location. In typically developing participants, the visual orienting reflex is longer for eyes than for arrows.

Objective: Paternal deletion and maternal uniparental disomy are the principal genetic subtypes associated with Prader-Willi syndrome (PWS). Recent clinical findings suggest differences in phenotype between these subtypes. The present experimental study addresses this issue using a cognitive psycho-physiological setup.

Adults with Prader-Willi syndrome (PWS) and normal controls participated in a cognitive psychophysiology study in which event-related brain activity was recorded in a visual and auditory oddball task. In both tasks, participants were instructed to press a hand key to a target stimulus. All participants had successful task performance but persons with PWS had more target omissions than controls in the visual oddball task.
