Placebo and three doses of methylphenidate (MPH) were crossed with 3 levels of behavioral modification (no behavioral modification, NBM; low-intensity behavioral modification, LBM; and high-intensity behavior modification, HBM) in the context of a summer treatment program (STP). Participants were 48 children with ADHD, aged 5–12. Behavior was examined in a variety of social settings (sports activities, art class, lunch) that are typical of elementary school, neighborhood, and after-school settings. Children received each behavioral condition for 3 weeks, order counterbalanced across groups. Children concurrently received in random order placebo, 0.15 mg/kg/dose, 0.3 mg/kg/dose, or 0.6 mg/kg/dose MPH, 3 times daily with dose manipulated on a daily basis in random order for each child. Both behavioral and medication treatments produced highly significant and positive effects on children’s behavior. The treatment modalities also interacted significantly. Whereas there was a linear dose–response curve for medication in NBM, the dose–response curves flattened considerably in LBM and HBM. Behavior modification produced effects as large as moderate doses, and on some measures, high doses of medication. These results replicate and extend to social-recreational settings previously reported results in a classroom setting from the same sample (Fabiano et al., School Psychology Review, 36, 195–216, 2007). Results illustrate the importance of taking dosage/intensity into account when evaluating combined treatments; there were no benefits of combined treatments when the dosage of either treatment was high but combination of the low-dose treatments produced substantial incremental improvement over unimodal treatment.  相似文献

The purpose of this study was to examine the longitudinal relationship between attention-deficit/hyperactivity disorder (ADHD) symptoms, emotion regulation (ER) ability, and depressive symptoms within a diverse community sample of 277 youth, ages 9–12 (56 % male). Participants were drawn from a larger study examining adolescent risk behaviors, and completed annual assessments over 3 years. Youth ADHD symptoms were assessed at Time 1 (T1) using the parent-reported Disruptive Behavior Disorders Rating Scale, ER was assessed with the parent-reported Emotion Regulation Checklist at Time 2 (T2), and youth depressive symptoms were assessed using the self-reported Revised Child Anxiety and Depression Scales at Time 3 (T3). Analyses examined T2 ER as a mediator between T1 ADHD symptoms (including the unique contributions of inattentive [IA] versus hyperactive/impulsive [HI] symptoms) and T3 depressive symptoms. Structural equation modeling (SEM) indicated the path model specified provided an excellent fit to the data. Tests of indirect effects suggested that T2 ER appears to be a significant mechanism that underlies the relationship between T1 ADHD and T3 depression, even when accounting for T1 oppositional defiant and depressive symptoms. Furthermore, while both T1 IA and HI symptoms had significant indirect effects on T3 depression through the mechanism T2 ER, HI proved a more robust predictor of T2 ER than IA. Results of this prospective study support cross-sectional findings pointing to ER as a potential mechanism linking ADHD and depressive symptoms in youth. Clinical implications and future directions are discussed.  相似文献

Purpose

The purpose of this study was to investigate the typical, peak, and variability in performance of both the offensive and defensive units of college football teams over the course of a season in predicting three objective team-level outcomes (win percentage, fan home game attendance, and bowl game payout).

Design/Methodology/Approach

Data were obtained from an archival sports database for 193 Bowl Subdivision college football teams for three separate seasons.

Findings

When all three types of performance were considered simultaneously, only typical performance significantly predicted win percentage and bowl game payout outcomes, and it explained between 19 % (for bowl game payout) and 49 % (for record) of the variance. All interactions between typical performance and performance variability were non-significant.

Implications

These null results point to a boundary condition in the relationship between performance variability and outcomes: whether the outcome is subject to evaluator attributional processes (e.g., raises, performance evaluations) or is more objective in nature. Although null, the present results question a sometimes implicit assumption that performance inconsistency is detrimental to organizational functioning.

Originality/Value

This is one of the first studies to examine outcomes of peak performance, typical performance, and performance variability at the team level. Additionally, most studies examining the outcomes of such performance use subjective outcomes such as performance ratings, whereas this study provides one of the first examinations using objective outcomes such as bowl game payout.  相似文献

This essay discusses Shakespeare’s adolescent Prince Hal, his relationship to his father, Henry IV, his rebellion, which included a turn to an anti-social mentor, a substitute father, Falstaff. This study explores Shakespeare’s portrayal of the evolution of the complex father-son relationship. Eventually, Prince Hal gives up his rebellion and takes on his adult role, becoming Henry V. Relevant aspects of adolescence are highlighted, including the transition from an adolescence dominated by a narcissistic object choice to an adulthood in which the ego ideal is the most prominent driving force of his behavior.  相似文献

The human visual system has evolved specialized neural mechanisms to rapidly detect faces. Its broad tuning for facial features is thought to underlie the illusory perception of faces in inanimate objects, a phenomenon called face pareidolia. Recent studies on face pareidolia suggest that the mechanisms underlying face processing, at least at the early stages of visual encoding, may treat objects that resemble faces as real faces; prioritizing their detection. In our study, we used breaking continuous flash suppression (b-CFS) to examine whether the human visual system prioritizes the detection of objects that induce face pareidolia over stimuli matched for object content. Similar to previous b-CFS results using real face stimuli, we found that participants detected the objects with pareidolia faces faster than object-matched control stimuli. Given that face pareidolia has been more frequently reported amongst individuals prone to hallucinations, we also explored whether this rapid prioritization is intact in individuals with schizophrenia, and found evidence suggesting that it was. Our findings suggest that face pareidolia engages a broadly tuned mechanism that facilitates rapid face detection. This may involve the proposed fast subcortical pathway that operates outside of visual awareness.  相似文献

Extending recent research efforts on the effects of personality and moods at work, this study examined the impact of personality traits and mood states in job burnout. Specifically, the field study examined the role of 2 personality traits and positive and negative moods (states) in burnout among nurses working at 2 hospitals. Results indicate that extra-version significantly predicted the diminished accomplishment component of burnout, and neuroticism significantly predicted the exhaustion and depersonalization components. Thus, the findings indicate that personality dimensions predict burnout components differentially. Further, positive moods mediated the relationship between extraversion and accomplishment, while negative moods partially mediated between neuroticism and exhaustion. Thus, moods exhibited both direct and mediating effects. Implications for management and suggestions for future research are offered.  相似文献

Tracking a digital pursuit rotor task was used to measure dual task costs of language production by young and older adults. Tracking performance by both groups was affected by dual task demands: time on target declined and tracking error increased as dual task demands increased from the baseline condition to a moderately demanding dual task condition to a more demanding dual task condition. When dual task demands were moderate, older adults' speech rate declined but their fluency, grammatical complexity, and content were unaffected. When the dual task was more demanding, older adults' speech, like young adults' speech, became highly fragmented, ungrammatical, and incoherent. Vocabulary, working memory, processing speed, and inhibition affected vulnerability to dual task costs: vocabulary provided some protection for sentence length and grammaticality, working memory conferred some protection for grammatical complexity, and processing speed provided some protection for speech rate, propositional density, coherence, and lexical diversity. Further, vocabulary and working memory capacity provided more protection for older adults than for young adults although the protective effect of processing speed was somewhat reduced for older adults as compared to the young adults.  相似文献

Several cases are presented of the intervention of a communal rabbi in the treatment of psychiatric patients. The rabbi was requested to intervene by the therapist when the issue of pathological guilt was encumbering further therapeutic progress.  相似文献
