Responsiveness in Interactions of Mothers and Sons with ADHD: Relations to Maternal and Child Characteristics 总被引:5,自引:0,他引:5
Johnston C Murray C Hinshaw SP William EP Hoza B 《Journal of abnormal child psychology》2002,30(1):77-88
We observed mother–child interactions, at baseline, in 136 families of 7–10-year-old boys with attention-deficit/hyperactivity disorder (ADHD) who were part of a large clinical trial, the Multimodal Treatment Study of Children with ADHD. Independent coders rated stylistic aspects of maternal behavior and factor analyses revealed a responsiveness factor that included overall responsiveness and sensitivity to the child, warmth and acceptance, and appropriate control. We examined relations between maternal responsiveness and (a) maternal depressive symptoms and maternal childhood ADHD symptoms, and (b) boys' ADHD and conduct problem symptoms. Controlling for all other variables, maternal responsiveness displayed a unique negative association with mother-reported child conduct problems, but not with child ADHD symptoms, and also was negatively related to maternal depressive symptoms. We discuss the unique association between mother-reported child conduct problems and parenting, and note the utility of studying parenting style in families of children with ADHD. We describe the results within the framework of a transactional model. 相似文献

The role of perceptual load in processing distractor faces 总被引:5,自引:0,他引:5
It has been established that successful ignoring of irrelevant distractors depends on the extent to which the current task loads attention. However, the previous load studies have typically employed neutral distractor stimuli (e.g., letters). In the experiments reported here, we examined whether the perception of irrelevant distractor faces would show the same effects. We manipulated attentional load in a relevant task of name search by varying the search set size and found that whereas congruency effects from meaningful nonface distractors were eliminated by higher search load, interference from distractor faces was entirely unaffected by search load. These results support the idea that face processing may be mandatory and generalize the load theory to the processing of meaningful and more complex nonface distractors. 相似文献

IQ on the rise: the Flynn effect in rural Kenyan children 总被引:4,自引:0,他引:4
Abstract - Multiple studies have documented significant IQ gains over time, a phenomenon labeled the Flynn effect. Data from 20 industrialized nations show massive IQ gains over time, most notably in culturally reduced tests like the Raven's Progressive Matrices. To our knowledge, however, this is the first study to document the Flynn effect in a rural area of a developing country. Data for this project were collected during two large studies in Embu, Kenya, in 1984 and 1998. Results strongly support a Flynn effect over this 14-year period, with the most significant gains found in Raven's matrices. Previously hypothesized explanations (e.g., improved nutrition; increased environmental complexity; and family, parental, school, and methodological factors) for the Flynn effect are evaluated for their relevance in this community, and other potential factors are reviewed. The hypotheses that resonate best with our findings are those related to parents' literacy, family structure, and children's nutrition and health. 相似文献

Saccade performance has been reported to be altered in Parkinson's disease (PD), however, with a large variability between studies as both motor and cognitive impairment interfere with oculomotor control. The aim of this study was to identify different patterns in saccade alterations in PD using a data-driven approach and to explore their relationship with cognitive phenotypes. Sixty-one participants with PD and 25 controls performed eye-tracking (horizontal and vertical prosaccades, antisaccades) and neuropsychological testing. Hierarchical cluster analysis was applied to the eye-tracking data to subsequently compare the clusters based on demographical, clinical and cognitive characteristics. The three identified clusters of saccade alterations differed in cognitive profiles from healthy controls, but not in PD-related motor symptoms or demographics. The rate of directive errors in the antisaccade task was increased in clusters 1 and 2. Further, cluster 1 was defined by a general disinhibition of reflexive saccades and executive dysfunction in the neuropsychological evaluation. In cluster 2, prolonged saccade latencies and hypometria were accompanied by multidomain cognitive impairment. The cluster 3 showed increased antisaccade latency and vertical hypometria despite lack of evidence for cognitive impairment. Our results suggest that there may be at least two opposing patterns of saccade alterations associated with cognitive impairment in PD, which may explain some of the contradictory results of previous studies. 相似文献

Prior research tends to find a positive relationship between religiosity and political participation. Explanations of this relationship have focused mostly on religiosity-generated organizational resources (e.g., civic skills), while paying less attention to psychological resources. We simultaneously examined different aspects of religiosity (belief, behavior, and belonging) and political participation (electoral and nonelectoral) in a structural equation model with two psychological resources as mediators: (1) “transcendent accountability”—seeing oneself as responsible to God or a higher power for one's impact on other people and the environment, and (2) “religiopolitical awareness”—perceiving the influence of one's religion and/or spirituality on one's political views and activities. Results from analyzing survey data from a US representative sample showed that transcendent accountability and religiopolitical awareness, whether together or awareness only, mediated positive relationships between religiosity (belief, private and public behaviors, and membership) and political participation (voting and other political activity), highlighting key psychological motivators of political participation. 相似文献

Peer relationships in ADDH and normal children: A developmental analysis of peer and teacher ratings
Charlotte Johnston William E. Pelham H. Allen Murphy 《Journal of abnormal child psychology》1985,13(1):89-100
Peer and teacher perceptions of younger and older ADDH and normal children were compared. Peer nominations on the Pupil Evaluation Inventory revealed that ADDH children received more nominations on the Aggression factor and fewer on the Likability factor. ADDH boys received more nominations on the Withdrawal factor. Generally, older children received fewer nominations, but age did not interact with diagnosis; that is, younger and older ADDH children were perceived by peers as equally deviant. Discriminant analyses showed that peer ratings were useful in discriminating between ADDH and normal boys, but not between ADDH and normal girls. Teacher ratings of peer behavior suggested that older ADDH girls were perceived as less disturbed than younger girls. However, teacher ratings of boys revealed no age by diagnosis interactions. Low to moderate correlations were found between peer and teacher ratings of ADDH boys, and the pattern of relationship varied with age.During the writing of this report, Charlotte Johnston was supported by a Sir James Lougheed Fellowship, Alberta Heritage Scholarship Fund. 相似文献

In this work, the tactual information transmission capabilities of a tactual display designed to provide stimulation along a continuum from kinesthetic movements to cutaneous vibrations are assessed. The display is capable of delivering arbitrary waveforms to three digits (thumb, index, and middle finger) within an amplitude range from absolute detection threshold to about 50 dB sensation level and a frequency range from dc to above 300 Hz. Stimulus sets were designed at each of three signal durations (125, 250, and 500 msec) by combining salient attributes, such as frequency (further divided into low, middle, and high regions), amplitude, direction of motion, and finger location. Estimated static information transfer (IT) was 6.5 bits at 500 mseC., 6.4 bits at 250 mseC., and 5.6 bits at 125 msec. Estimates of IT rate were derived from identification experiments in which the subject’s task was to identify the middle stimulus in a sequence of three stimuli randomly selected from a given stimulus set. On the basis of the extrapolations from these IT measurements to continuous streams, the IT rate was estimated to be about 12 bits/seC., which is roughly the same as that achieved by Tadoma users in tactual speech communication. 相似文献

Reaction times (RTs) were measured for decisions in a same-different discrimination of successive vowel-consonant nonsense syllables. Averaged data showed that “same” RTs were faster than “different” RTs and that the “different” RT decreased as the number of features (Wickelgren, 1966) by which a pair contrasted increased. For individual phonemic comparisons, two of the dependent variables, P(S I d), or probability of responding “same” to a different trial and the mean correct “different” RT, were related in that the RT increased as P(S I d) increased. The size of the difference between “same” and “different” RTs for a given phonemic contrast was directly related to P(S | d). The difficulty of a comparison, as described by P(S I d) and by the difference between correct “same” and “different” RTs, was explained through a markedness classification of phonemes. 相似文献

It is argued that current attempts to investigate the process of family therapy might benefit from the application of discursive and narrative analytic techniques. An example of such an analysis is given, taking the work of an experienced family therapist with one family seeking help in dealing with the aftermath of a marital separation.' The theme of how to deal with change'as it materializes in the discussions during therapy is selected for detailed examination in this paper. It is argued that there are two main discourses on this theme evident in the family's discussions, one being that the separation has occurred and its consequences should now he left to arise naturally; the other being that the effects of the separation need to be actively managed. It is suggested that this analytic procedure can dramatize the subtle changes in family discourses during therapy; its limitations in terms of generalizability, and the difficulties of dealing with huge amounts of complex material, are also noted. 相似文献

A clinical study to compare clinically-observed with task-elicited family interaction was carried out as follows. Twelve families receiving family therapy were administered a series of tasks by tape-recorder. The therapist and an independent observer recorded interaction patterns in six dimensions (Alliance, Parenting, Marital Relationship, Communication, Affective Status and Boundary Integrity) and the results were compared with what was known clinically. Except for conflict the Task Interview revealed the main clinical features; however, it also revealed significant new information in all cases but one. The study has implications for clinical work. 相似文献
