A significant literature suggests that youth diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) are at increased risk for later depression relative to youth without ADHD. Youth with co-occurring ADHD and depression experience more serious impairments and worse developmental outcomes than those with either disorder alone, including increased rates of suicidal ideation and suicide completion. Despite these very serious outcomes, few studies have examined the mechanisms underlying the relationship between ADHD and depression in youth. The present study examined emotion regulation (ER) as a mediator of the relationship between ADHD and depressive symptoms in 69 youth between the ages of 10 and 14, with (n?=?37) and without (n?=?32) ADHD. Parent and youth ratings of depressive symptoms and ER were collected. Youth with ADHD reported significantly more depressive symptoms and poorer ER ability relative to youth without ADHD. ER fully mediated the relationship between ADHD and depressive symptoms. Limitations and clinical implications are discussed.  相似文献

The current study examined the distal, proximal, and time-varying effects of parents’ alcohol-related consequences on adolescents’ substance use. Previous studies show that having a parent with a lifetime diagnosis of alcoholism is a clear risk factor for adolescents’ own substance use. Less clear is whether the timing of a parent’s alcohol-related consequences differentially predicts the adolescent’s own substance involvement. Using a multilevel modeling approach, we tested whether adolescents showed elevated rates of alcohol, heavy alcohol, marijuana and other illegal drug use (a) at the same time that parents showed alcohol-related consequences (time-varying effects), (b) if parents showed greater alcohol-related consequences during the child’s adolescence (proximal effects), and (c) if parents had a lifetime diagnosis of alcoholism that predated the child’s adolescence (distal effects). We tested these effects in a high-risk sample of 451 adolescents assessed over three waves beginning at ages 11–15 from 1988 to 1991 (53?% male, 71?% non-Hispanic Caucasian, 54?% children of alcoholic parents and 46?% matched controls). Strong and consistent distal effects of parent alcoholism on adolescent’s substance use were found, though no additional risk was associated with proximal effects. Limited time-varying effects were also found. The importance of differentiating the timing effects of parent alcoholism in identifying underlying mechanisms of risk for adolescent substance use is discussed.  相似文献

This study used the Still Face Paradigm to investigate the relationship of maternal interaction on infants' emotion regulation responses. Seventy infant-mother dyads were seen at 4 months and 25 of these same dyads were re-evaluated at 9 months. Maternal interactions were coded for attention seeking and contingent responding. Emotional regulation was described by infant stress reaction and overall positive affect. Results indicated that at both 4 and 9 months mothers who used more contingent responding interactions had infants who showed more positive affect. In contrast, mothers who used more attention seeking play had infants who showed less positive affect after the Still Face Paradigm. Patterns of stress reaction were reversed, as mothers who used more attention seeking play had infants with less negative affect. Implications for intervention and emotional regulation patterns over time are discussed.  相似文献

The purpose of the present study was to analyze the movement patterns of free-throw shooters in basketball at different skill levels. There were two points of interest. First, to explore what information can be drawn from the movement pattern and second, to examine the methodological possibilities of pattern analysis. To this end, several qualitative and quantitative methods were employed. The resulting data were converged in a triangulation. Using a special kind of ANN named Dynamically Controlled Networks (DyCoN), a 'complex feature' consisting of several isolated features (angle displacements and velocities of the articulations of the kinematic chain) was calculated. This 'complex feature' was displayed by a trajectory combining several neurons of the network, reflecting the devolution of the twelve angle measures over the time course of each shooting action. In further network analyses individual characteristics were detected, as well as movement phases. Throwing patterns were successfully classified and the stability and variability of the realized pattern were established. The movement patterns found were clearly individually shaped as well as formed by the skill level. The triangulation confirmed the individual movement organizations. Finally, a high stability of the network methods was documented.  相似文献

Objectives

This intervention study evaluated the effects of exercise in old age on views on one’s own aging and on direct approach motivation for physical activity. It further examined the mechanism between these variables.

Design

Two hundred forty-seven healthy women aged 70−93 years were randomized to an exercise course (n = 86), an active (n = 85), or a passive control group (n = 76) for a 6-month participation in Berlin, Germany. Activity interventions (3 × 1.5 h/wk) were conducted using standardized manuals.

Method

Group differences in changes of views on aging and direct approach were evaluated by analyses of covariance adjusted for baseline. A mediating effect of direct approach between exercise participation and views on aging was tested with percentile-based bootstrapping.

Results

In contrast to both the active and the passive control groups, higher direct approach, F(2, 226) = 6.97, p = .001, and less aging dissatisfaction, F(2, 225) = 5.39, p = .005, were observed in the exercise group after 6 months. Exercise had an indirect beneficial effect on aging dissatisfaction through direct approach, B = −0.31, 95% CI = −0.68 to −0.05.

Conclusion

In women above 70 years, exercise participation increases direct approach motivation which in turn leads to lower aging dissatisfaction. This shows that exercise holds the potential to overcome subjective ageist bias.  相似文献

Two studies were conducted to explore the conditions that elicit autobiographical memory problems in abuse victims and the mechanism that underlie them. In Study 1 older adolescents (n=80) with and without self-reported abuse histories completed a modified version of the Autobiographical Memory Test (AMT-U); participants were given an unlimited amount of time to provide specific memories in response to cue words. Participants also completed measures of depression and post-traumatic stress disorder (PTSD), working memory, and attentional biases. This study found that abuse severity and PTSD symptoms were positively related to memory specificity on the AMT-U. In Study 2 older adolescents (n=78) with and without self-reported abuse histories completed the traditional (timed) version of the AMT. Participants also completed measures of working memory, attentional biases, self-reported coping, and psychopathological symptoms (i.e., depression and PTSD). In this study the opposite relationship was observed, such that abuse severity was related to poorer memory specificity, but this relationship was explained by disengagement coping and PTSD symptoms. This work suggests that poor memory specificity may represent a form of avoidance, but the application of avoidant mechanisms depends on the remembering context.  相似文献

It is generally thought that individuals with Asperger's syndrome and high-functioning autism (AS/HFA) have deficits in theory of mind. These deficits have been previously linked to problems with social cognition. However, we reasoned that AS/HFA individuals' Theory of Mind deficits also might lead to problems with emotion regulation. To assess emotional functioning in AS/HFA, 27 AS/HFA adults (16 women) and 27 age-, gender-, and education-matched typically developing (TD) participants completed a battery of measures of emotion experience, labeling, and regulation. With respect to emotion experience, individuals with AS/HFA reported higher levels of negative emotions, but similar levels of positive emotions, compared with TD individuals. With respect to emotion labeling, individuals with AS/HFA had greater difficulties identifying and describing their emotions, with approximately two-thirds exceeding the cutoff for alexithymia. With respect to emotion regulation, individuals with AS/HFA used reappraisal less frequently than TD individuals and reported lower levels of reappraisal self-efficacy. Although AS/HFA individuals used suppression more frequently than TD individuals, no difference in suppression self-efficacy was found. It is important to note that these differences in emotion regulation were evident even when controlling for emotion experience and labeling. Implications of these deficits are discussed, and future research directions are proposed.  相似文献

Cognition and emotion interact to determine ongoing behaviors. In this study, we investigated the interaction between cognition and emotion during response inhibition using the stop-signal task. In Experiment 1, low-threat stop-signals comprising fearful and happy face pictures were employed. We found that both fearful and happy faces improved response inhibition relative to neutral ones. In Experiment 2, we employed high-threat emotional stimuli as stop signals, namely stimuli previously paired with mild shock. In this case, inhibitory performance was impaired relative to a neutral condition. We interpret these findings in terms of the impact of emotional stimuli on early sensory/attentional processing, which resulted in improved performance (Experiment 1), and in terms of their impact at more central stages, which impaired performance (Experiment 2). Taken together, our findings demonstrate that emotion can either enhance or impair cognitive performance depending on the emotional potency of the stimuli involved.  相似文献
