ABSTRACT Normal aging has been associated with executive control deficits, but it is as yet unclear whether different executive subprocesses are differentially affected during the course of aging. The present study aimed to investigate age effects on a range of executive control subcomponents. Four consecutive age groups (20–30 years, 31–45 years, 46–60 years, 61–75 years), matched on present state IQ and mood, were compared on tasks of strategic memory processing, verbal fluency, reasoning, inhibition, task management, and self-rating of executive abilities. Deficits concerning the suppression of habitual and experimentally induced prepotent response tendencies and the ability to efficiently divide attention were observed in subjects over 60 years of age compared to the younger groups, while memory, verbal fluency, and reasoning were largely unaffected. Results suggest a sharp decline of executive function after age 60 and a differential course of different executive subcomponents across aging, adding further support to a multi-dimensional model of executive function. 相似文献

Background
The aim of the present study was to compare psychological distress and substance use between migrant and non-migrant populations in a socially deprived area of Berlin.Methods
A population-based random sample stratified for age (18?C57?years) and gender (50% female) was retrieved from the registration office. A total of 143 persons were included in the study. The participation rate was 48.5% when contact was established. Psychological distress was assessed using the General Health Questionnaire (GHQ-28) with its four subscales, somatic symptoms, anxiety/insomnia, social dysfunction and severe depression. Substance use was quantified using the Alcohol Use Identification Disorder Test (AUDIT) and the Fagerstr?m Test for Nicotine Dependence (FTND).Results
Of the study population 51.3% were first or second generation migrants and lived more often in single households. Migrants had lower educational levels and lower employment rates. The mean scores of migrants and non-migrants did not differ on any of the subscales somatic symptoms, anxiety/depression, social dysfunction or severe depression of the GHQ-28. Non-migrants showed significantly higher risks regarding alcohol use.Discussion
The present study did not reveal any differences regarding symptom profiles in the spectrum of anxiety and depression between non-migrants and migrants who lived in a socially deprived area. Migrants may compensate higher social risk profiles with lower risks regarding alcohol use. Larger samples have to inform on possible differences regarding smoking and other substances. 相似文献113.

Attenuated affective processing is hypothesized to play a role in the development and maintenance of obesity. Using an affective priming task measuring automatic affective processing of verbal stimuli, a group of 30 obese participants in a weight-loss program at the Psychosomatic University Clinic Bonn (M age = 48.3, SD = 10.7) was compared with a group of 25 participants of normal weight (M age = 43.6, SD = 12.5). A smaller affective priming effect was observed for participants with obesity, indicating less pronounced reactions to valenced adjectives. The generally reduced affective processing in obese participants was discussed as a possible factor in the etiology of obesity. Individuals who generally show less pronounced affective reactions to a given stimulus may also react with less negative affect when confronted with weight gain or less positive affect when weight is lost. Consequently, they could be expected to be less motivated to stop overeating or to engage in dieting and will have a higher risk of becoming or staying obese. 相似文献

The impact of nonresponse on estimates of mental health problems was examined in a prospective teacher screen in a community
survey of 9,155 7–9 year olds. For 6,611 of the children, parents consented to participation in the actual study (Responders),
while for 2,544 children parental consent was not obtained (Nonresponders). The teacher screen involved assessment of a broad
set of symptoms of mental health problems and functional impairment. Calculations of non-response coefficients, a function
of effect sizes and non-response proportion, revealed only ignorable nonresponse bias for both mean scores and correlations.
However, the results from binary logistic regressions revealed that children ascribed signs of mental health problems by their
teachers were less likely to participate. This was most frequent among children with only moderate symptoms. However, it also
involved children with high symptom scores related to inattention, hyperactivity, emotions and peer relationship problems.
These findings suggest that measures based on effect size can underestimate the magnitude of non-response bias and that a
logistic regression approach may be more appropriate for studies geared at estimating prevalence of mental health problems
in children.

In order to investigate whether the Lidcombe Program effects a short-term reduction of stuttered speech beyond natural recovery, 46 German preschool children were randomly assigned to a wait-contrast group or to an experimental group which received the Lidcombe Program for 16 weeks. The children were between 3;0 and 5;11 years old, their and both of their parents’ native language was German, stuttering onset had been at least 6 months before, and their stuttering frequency was higher than 3% stuttered syllables. Spontaneous speech samples were recorded at home and in the clinic prior to treatment and after 4 months. Compared to the wait-contrast group, the treatment group showed a significantly higher decrease in stuttered syllables in home-measurements (6.9%SS vs. 1.6%SS) and clinic-measurements (6.8%SS vs. 3.6%SS), and the same increase in articulation rate. The program is considered an enrichment of currently applied early stuttering interventions in Germany.
Educational objectives: Readers will discuss and evaluate: (1) the short-term effects of the Lidcombe Program in comparison to natural recovery on stuttering; (2) the impact of the Lidcombe Program on early stuttering in German-speaking preschool children. 相似文献

Congenital amusia refers to a lifelong disorder of music processing and is linked to pitch-processing deficits. The present study investigated congenital amusics’ short-term memory for tones, musical timbres and words. Sequences of five events (tones, timbres or words) were presented in pairs and participants had to indicate whether the sequences were the same or different. The performance of congenital amusics confirmed a memory deficit for tone sequences, but showed normal performance for word sequences. For timbre sequences, amusics’ memory performance was impaired in comparison to matched controls. Overall timbre performance was found to be correlated with melodic contour processing (as assessed by the Montreal Battery of Evaluation of Amusia). The present findings show that amusics’ deficits extend to non-verbal sound material other than pitch, in this case timbre, while not affecting memory for verbal material. This is in line with previous suggestions about the domain-specificity of congenital amusia. 相似文献

Effects of self‐enhancement and socially desirable responding (SDR) on rater agreement for personality profiles were studied in 304 students. Dyads of participants described themselves and their peer on the Revised NEO Personality Inventory (NEO‐PI‐R) that measures 30 facets of personality. In addition, participants filled in six scales measuring self‐enhancement or SDR. Data analyses focussed on moderator and suppressor effects of SDR on the similarity between self‐reported and other reported NEO‐PI‐R profiles. Three kinds of profile agreement were distinguished: (a) normative agreement; (b) distinctive agreement and (c) profile normativeness, that is, how strongly a self‐reported personality profile resembled the average profile of all participants. There were no moderator or suppressor effects on distinctive agreement, but SDR predicted profile normativeness quite strongly. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

This study investigated whether older adults could acquire the ability to perform 2 cognitive operations in parallel in a paradigm in which young adults had been shown to be able to do so (K. Oberauer & R. Kliegl, 2004). Twelve young and 12 older adults practiced a numerical and a visuospatial continuous memory updating task in single-task and dual-task conditions for 16 to 24 sessions. After practice, 9 young adults were able to process the 2 tasks without dual-task costs, but none of the older adults had reached the criterion of parallel processing. The results suggest a qualitative difference between young and older adults in how they approach dual-task situations. 相似文献
