The comparison group (CG) included 92 asthmatic children and adolescents receiving standard medical treatments. Patients were aged between 8 and 16 years and were predominantly male. The health-related quality of life was measured with the German version of the "Paediatric Asthma Quality of Life Questionnaire." Interviews were carried out for IG 2 weeks before the commencement of their inpatient stay and 1 year after their stay ended. The same time schedule was carried out for CG. All patients reported a mild to moderate impairment of their quality of life. Girls described a slightly lower quality of life than boys. With increasing asthma severity, quality of life decreased. Inpatients described a lower quality of life than CG at enrollment. Inpatient rehabilitation resulted in a greater improvement of quality of life over time for IG than for CG. Gender and severity status had no effect on this time course. The only modestly affected quality of life may reflect the good adaptation to the disease and medical treatment. Children and adolescents in the IG recorded improvements in their quality of life. Differences in quality of life based on gender and disease severity were not shown to influence the improvements.

There have been only a few studies to assess the extent of problems experienced by the parents. Objective To assess the psychosocial well-being of parents caring for a young child with AD and to examine the relationship between parental quality of life and disease-related and sociodemographic variables. Methods One hundred and eighty-seven parents of young children with AD attending an inpatient rehabilitation clinic participated in the study. At admission, parents completed a set of questionnaires (assessing health-related quality of life, coping with the disease, family functioning). Dermatologists assessed disease severity using the severity scoring of AD index (SCORAD). Results In general, parents cope well with their situation. Compared with normal values, high rates of psychological distress were observed in a subsample of parents of children with AD. Parents of children with a higher severity of disease reported a significantly higher impact on family functioning, a greater financial burden and a higher level of disease management. Parental disease management could be predicted by the familial situation, their personal well-being and the severity of disease of their child. Differences attributed to their child's gender or age were not observed. Conclusions Childhood AD has a profound impact on the emotional and social well-being of many of the parents.

First, we used peripheral cues, rather than the centrally presented cues of earlier studies. Second, we spatially cued attention in vision and audition to visual and auditory targets.

Old adults showed disproportional performance deficits on intrusion probes only in terms of reaction times, whereas young adults with low WMC showed them only in terms of errors.

Older adults experience a progressive decline in several cognitive functions and show deficiencies in neuropsychological tasks requiring flexible adaptation to external feedback, which could be related to impairments in reward association learning. To study the effect of aging on stimulus-reward association learning 20 young and 20 older adults performed a probabilistic object reversal task (pORT) along with a battery of tests assessing executive functions and general intellectual abilities. The pORT requires learning and reversing associations between actions and their outcomes. Older participants collected fewer points, needed more trials to reach the learning criterion, and completed less blocks successfully compared to young adults. This difference remained statistically significant after correcting for the age effect of other tests assessing executive functions. This suggests that there is an age-related difference in reward association learning as measured using the pORT, which is not closely related to other executive functions with respect to the age effect. In human aging, structural alterations of reward detecting structures and functional changes of the dopaminergic as well as the serotonergic system might contribute to the deficit in reward association learning observed in this study.

The explanation of center-embedding difficulty is a novel one that derives from the model's complete reliance on discriminating retrieval cues in the absence of an explicit representation of serial order information. All fits were obtained with only 1 free scaling parameter fixed across the simulations; all other parameters were ACT-R defaults. The modeling results support the hypothesis that fluctuating activation and similarity-based interference are the key factors shaping working memory in sentence processing.

There was little interference between storage of the two sets, and between storage and processing, but parallel execution of the two operations was not possible. In Experiment 2, all elements in both memory sets were updated in random order. There was substantial interference between memory for the numerical and the spatial sets, and between storage and processing. Parallel execution of two operations was again not possible. Moreover, trying to do two operations simultaneously resulted in impaired memory of final results. The results support the distinction between the activated part of long-term memory that can hold elements currently not needed for processing, and a more central, capacity-limited part of working memory that provides access to its contents for processing}, language = {en} } @article{VollmeyerRheinberg2006, author = {Vollmeyer, Regina and Rheinberg, Falko}, title = {Motivational Effects on self-Regulated learning with different Tasks}, series = {Educational psychology review}, volume = {18}, journal = {Educational psychology review}, number = {3}, publisher = {Springer}, address = {New York}, issn = {1040-726X}, doi = {10.1007/s10648-006-9017-0}, pages = {239 -- 253}, year = {2006}, abstract = {In our cognitive motivational process model (Vollmeyer \& Rheinberg, Zeitschrift f{\"u}r P{\"a}dagogische Psychologie, 12:11-23, 1998) we assume that initial motivation affects performance via motivation during learning and learning strategies.

Verhaeghen et al. reported a shift over practice from a step function to a linear slope of reaction times over set size and argued that it reflects the expansion of the focus. With an improved counterbalancing scheme, a continuously increasing slope was found even without practice in Experiment 2.

They exhibited a strong tendency to fixate at the word centre in single-fixation cases and at the word beginning in multiple-fixation cases. Different from spaced alphabetic script, initial fixations falling at the end of words were no more likely to be followed by a refixation than initial fixations at word centre. Further, single fixations were shorter than first fixations in two-fixation cases, which is opposite to what is found in Roman script.

Two satisfactory measurement models for the RTs could be established: A general factor model without constraints on the loadings and a nested model with two correlated factors, distinguishing compatible from arbitrary mappings, with constraints on the loadings. Structural models additionally including factors for working memory and intelligence showed that the nested model with correlated factors is superior in fit. Working-memory capacity and fluid intelligence were correlated strongly with the nested factor for the RT tasks with arbitrary mappings, and less with the general RT factor. The results support the hypothesis that working memory is needed to maintain arbitrary bindings between stimulus representations and response representations, and this could explain the correlation of working-memory capacity with speed in choice RT tasks}, language = {en} } @article{Schwarz2006, author = {Schwarz, Wolfgang}, title = {On the relation between the redundant signals effect and temporal order judgments: Parametric data and a new model}, year = {2006}, abstract = {Paradigms used to study the time course of the redundant signals effect (RSE; J.

Parametric data (13 stimulus onset asynchronies) from an experiment with pairs of visual stimuli (626-nm LEDs) confirm that, relative to central signals (3 degrees), peripheral signals (35 degrees) yield slower reaction times, more strongly modulated RSE time-course functions, and flatter TOJ psychometric functions.

These "fixational" eye movements counteract perceptual fading, a consequence of fast adaptation of the retinal receptor systems to constant input. The most important contribution to fixational eye movements is produced by microsaccades; however, a specific function of microsaccades only recently has been found. Here we show that the occurrence of microsaccades is correlated with low retinal image slip approximate to 200 ms before microsaccade onset. This result suggests that microsaccades are triggered dynamically, in contrast to the current view that microsaccades are randomly distributed in time characterized by their rate-of-occurrence of 1 to 2 per second. As a result of the dynamic triggering mechanism, individual microsaccade rate can be predicted by the fractal dimension of trajectories.

ERPs were recorded from Fz, Cz, and Pz, using an auditory oddball paradigm. Sinus tones of 60 dB HL were presented binaurally at 1,000 Hz (standard stimulus) and 2,000 Hz (target stimulus), at a relative frequency ratio of 80:20. Two trial blocks of 250 stimuli each were collected. Results indicated that only COAs with paternal delinquency displayed significant differences from the control group, characterized by reduced P300 amplitude at frontal site and in the second trial block. Thus, the combination of fathers' alcoholism and delinquency was more likely to relate to attenuated P300 amplitude in the offspring than paternal alcoholism alone.

We show that these surrogates are well suited to test for complex synchronization, which makes it possible to systematically assess the reliability of synchronization analyses. We then apply the TS to study binocular fixational movements and find strong indications that the fixational movements of the left and right eye are phase synchronized.

Sexual aggression victimization and perpetration was measured with a Chilean Spanish version of the Sexual Aggression and Victimization Scale (SAV-S), which includes three coercive strategies (use or threat of physical force, exploitation of an incapacitated state, and verbal pressure), three victim-perpetrator constellations (current or former partners, friends/acquaintances, and strangers), and four sexual acts (sexual touch, attempted sexual intercourse, completed sexual intercourse, and other sexual acts, such as oral sex). Overall, 51.9\% of women and 48.0\% of men reported at least one incident of sexual victimization, and 26.8\% of men and 16.5\% of women reported at least one incident of sexual aggression perpetration since the age of 14. For victimization, only few gender differences were found, but significantly more men than women reported sexual aggression perpetration. A large proportion of perpetrators also reported victimization experiences. Regarding victim-perpetrator relationship, sexual aggression victimization and perpetration were more common between persons who knew each other than between strangers. Alcohol use by the perpetrator, victim, or both was involved in many incidents of sexual aggression victimization and perpetration, particularly among strangers.
