The present study evaluated the interactive behavior of three groups of mothers and their 3-month-old infants in the Face-to-Face Still-Face paradigm. The mothers had either a clinical diagnosis of major depressive disorder (MDD, n = 33) with no comorbidity, a clinical diagnosis of panic disorder (PD, n = 13) with no comorbidity, or no clinical diagnosis (n = 48). The sample was selected to be at otherwise low social and medical risk, and all mothers with PD or MDD were in treatment. The findings indicated that (a) infants of mothers with PD or MDD displayed the traditional still-face and reunion effects described in previous research with nonclinical samples; (b) the 3-month-old infants in this study showed similar, but not identical, gender effects to those described for older infants; and (c) there were no patterns of maternal or infant interactive behavior that were unique to the PD, MDD, or control groups. These results are discussed in light of mothers' risk status, receipt of treatment, severity of illness, and comorbidity of PD and MDD. 相似文献

Two studies of college students in the US utilized a new methodological approach in which participants arranged their multiple family members (i.e. parents, siblings, aunts, and uncles) within a series of relationship network grids. These grids measured participants’ own feelings of communal responsiveness toward and perceived feelings of communal responsiveness from each family member relative to one another. The results of Study 1 (N = 86) and Study 2 (N = 111) supported the hypotheses that (1) people perceive more responsiveness from female family members than from male family members and (2) people feel more responsive toward female than toward male family members. Study 2 provided evidence that these associations were mediated by felt and perceived intimacy, dependence, and obligation, but not liking. 相似文献

The predictive validity of symptom criteria for different subtypes of ADHD among children who were impaired in at least one
setting in early childhood was examined. Academic achievement was assessed seven times over 8 years in 125 children who met
symptom criteria for ADHD at 4–6 years of age and in 130 demographically-matched non-referred comparison children. When intelligence
and other confounds were controlled, children who met modified criteria for the predominantly inattentive subtype of ADHD
in wave 1 had lower reading, spelling, and mathematics scores over time than both comparison children and children who met
modified criteria for the other subtypes of ADHD. In some analyses, children who met modified criteria for the combined type
had somewhat lower mathematics scores than comparison children. The robust academic deficits relative to intelligence in the
inattentive group in this age range suggest either that inattention results in academic underachievement or that some children
in the inattentive group have learning disabilities that cause secondary symptoms of inattention. Unexpectedly, wave 1 internalizing
(anxiety and depression) symptoms independently predicted deficits in academic achievement controlling ADHD, intelligence,
and other predictors. 相似文献

To estimate the prevalence of being well-adjusted in adolescence, boys and girls with (n = 96) and without (n = 126) attention-deficit/hyperactivity disorder (ADHD) were assessed seven times in eight years starting when they were 4–6 years
of age. Symptoms of ADHD, ODD/CD, and depression/anxiety in addition to social skills and social preference were gathered
using multiple methods and informants. Being well-adjusted was defined by surpassing thresholds in at least four of the five
domains. At the 7- and 8-year follow-up, when youth were 11–14 years old, probands were significantly less likely to be well-adjusted
relative to age- and ethnicity-matched control children. Only a minority of children with ADHD was well-adjusted in adolescence
when emotional, behavioral, and social domains were considered simultaneously. Even when their ADHD symptoms improved over
time, most probands exhibited significant impairment 7–8 years after their initial assessment. 相似文献

Recent studies suggest that most of what parents know about their adolescent offspring's whereabouts and companions is the result of youth disclosure, rather than information gained through active parental monitoring. This raises the possibility that parental knowledge is spuriously correlated with youth delinquency solely because the most delinquent youth disclose the least information to parents (because they have the most to hide). We tested this spurious association hypothesis using prospective data on offspring of a nationally representative sample of US women, controlling demographic and contextual covariates. In separate analyses, greater parental knowledge of their offspring's peer associations at both 12-13 years and at 14-15 years was associated with lower odds of being in the top 1 standard deviation of youth-reported delinquency at 16-17 years, controlling for delinquency at the earlier ages. The extent to which parents set limits on activities with peers at 14-15 years did not mediate or moderate the association between parental knowledge and delinquency, but it did independently predict future delinquency among adolescents living in high-risk neighborhoods. This suggests that the association between parental knowledge and future delinquency is not solely spurious; rather parental knowledge and limit setting are both meaningful predictors of future delinquency. 相似文献

We examined the semantic impairment for natural kinds in patients with probable Alzheimer's disease (AD) and semantic dementia (SD) using an inductive reasoning paradigm. To learn about the relationships between natural kind exemplars and how these are distinguished from manufactured artifacts, subjects judged the strength of arguments such as "Humans have a chemical called sebum. Therefore, frogs have a chemical called sebum." These judgments depend on subjects' perception of the similarity between the familiar objects named in the premise and the conclusion. Controls rated arguments generalizing from a natural kind to an artifact as significantly weaker than arguments generalizing from one natural kind to another natural kind. SD patients demonstrated a graded profile of generalization without evidence of a categorical distinction between natural kinds and artifacts. AD patients' judgments also suggested more difficulty than controls at distinguishing between natural kinds and artifacts. Both SD patients and AD patients resembled controls in their judgments of arguments where both objects are from the natural kinds category. Semantic knowledge thus appears to be sufficiently preserved in both AD and SD to support within-category similarity judgments. We suggest that SD patients may be impaired in part at identifying the features critical to diagnosing membership in a semantic category, while AD patients' performance is consistent with their semantic categorization deficit. 相似文献

工作记忆是当前认知心理学中的一个研究热点,而其言语子系统与视觉子系统之间的关系又是一个颇具争论性的问题。实验1、2采用双任务范式考察了言语工作记忆对视觉工作记忆的影响。结果发现,满负荷言语负载条件下的视觉记忆的成绩显著低于无言语负载条件。这表明,言语工作记忆影响了视觉工作记忆任务的完成。 相似文献

负启动(NP)范式是用来研究选择性注意中分心信息抑制的一种实验技术.本研究将经典的NP范式修改成"分步启动显示的NP范式",并通过实验1、2分别探讨了"分步启动显示的NP范式"是否适用于选择性注意中分心信息抑制的研究和记忆提取抑制研究的可行性.实验1发现了NP效应,表明这种范式与经典的NP范式一样,能适用于选择性注意中分心信息抑制的研究.实验2也发现了NP效应,表明这种范式研究记忆提取抑制是可行性. 相似文献

Most theoretical accounts of backward blocking place heavy stress on the necessity of the target cue having been trained in compound with the competing cue to produce a decrement in responding. Yet, other evidence suggests that a similar reduction in responding to the target cue can be observed when the outcome is later paired with a novel cue never trained in compound with the target cue (interference between cues trained apart). The present experiment shows that pairing another nonassociated cue with the same outcome may be sufficient to produce a decremental effect on the target cue, but the presence of a within-compound association between the target and the competing cue adds to this effect. Thus, both interference between cues trained apart and within-compound associations independently contribute to backward blocking. 相似文献
