Cultural differences in illness perceptions and treatment access of teens with attention deficit/hyperactivity disorder (ADHD) are evident yet under studied. The purpose of this qualitative paper is to explore how African-American teenagers describe and narrate stories about their lives with ADHD. Data were gathered from four African-American teens in the Southern United States through a qualitative experience sampling method, and stories were analyzed using narrative analysis framed within the context of African-American rhetorical traditions. We argue that the study of teen-constructed narratives and culturally-situated talk are tools that can improve communication between healthcare providers and teens by illuminating the ways teens construct their personalized realities of ADHD.  相似文献

Four studies document the rejection of moral rebels. In Study 1, participants who made a counterattitudinal speech disliked a person who refused on principle to do so, but uninvolved observers preferred this rebel to an obedient other. In Study 2, participants taking part in a racist task disliked a rebel who refused to go along, but mere observers did not. This rejection was mediated by the perception that rebels would reject obedient participants (Study 3), but did not occur when participants described an important trait or value beforehand (Study 4). Together, these studies suggest that rebels are resented when their implicit reproach threatens the positive self-image of individuals who did not rebel.  相似文献

A study was conducted with 128 female college students to test the hypothesis that when observers feel vulnerable to rape, they are more likely to blame a rape victim3 and are less willing to offer social support. Similarity and empathy were expected to moderate the effects of perceived vulnerability on blame and predict greater social support. Assumptions about the world were predicted to be associated with greater blame. A multivariate model was tested with structural equation modeling techniques. Perceived vulnerability did not directly or indirectly predict blame. However, similarity directly predicted less blame and indirectly predicted greater social support through associations with blame, perceived vulnerability, and empathy. World assumptions directly predicted greater blame and indirectly predicted less social support through blame. These findings suggest that blame and social support are interrelated processes which are associated with social observers' perceptions of the victim and their basic assumptions about the world.  相似文献

A procedure for operant analysis of aggressive behavior was derived from multi-element assessment methods that have been previously applied to both self-injurious and stereotypic responding. Analog sessions included No Interaction Baseline, Social Disapproval, Demand, Social Reinforcement, and Discriminated Extinction conditions, repeatedly presented within a multi-element design. Three men with differing severity of mental retardation, communicative deficits and aggressive behavior were exposed to multiple brief analog sessions embedded within their normal meal-time routines in group home settings. Mean frequencies of aggressive behavior and concurrent eating indicate that, while aggressive behavior was negatively reinforced in all three participants, both social and non-social contingencies were also prominent. The same contingencies which have been demonstrated to maintain self-injury and stereotypic behavior can therefore also maintain aggression. Results suggest the feasibility of conducting relatively non-intrusive analog assessments in community residences, and support the-extension of functional analysis across differing classes of aberrant behavior.  相似文献

This study investigated the maternal concerns and emotions that may regulate one form of sensitive parenting, support for children's immediate desires or intentions. While reviewing a videotape of interactions with their 1-year-olds, mothers who varied on depressive symptoms reported concerns and emotions they had during the interaction. Emotions reflected outcomes either to children (child-oriented concerns) or to mothers themselves (parent-oriented concerns). Child-oriented concerns were associated with fewer negative emotions and more supportive behavior. Supportive parenting was high among mothers who experienced high joy and worry and low anger, sadness, and guilt. However, relations depended on whether emotions were child or parent oriented: Supportive behavior occurred more when emotions were child oriented. In addition, as depressive symptoms increased, mothers reported fewer child-oriented concerns, fewer child-oriented positive emotions, and more parent-oriented negative emotions. They also displayed less supportive behavior. Findings suggest that support for children's immediate intentions may be regulated by parents' concerns, immediate emotions, and depressive symptoms.  相似文献

The present study examines the moderating effects of two personality types in the personal control-job stress relationship. Individuals with a high activity level and belief in powerful others (dimension of external locus of control) had the strongest negative relationship between personal control and psychological anxiety. In addition, individuals with a high belief in chance or fate (dimension of external locus of control) had the strongest negative relationship between personal control and pulse rate. The findings suggest that employees with a high activity level and/or external locus of control benefit the most from having control over their work environment.  相似文献

Most treatments for stereotypy involve arrangements of antecedent or consequent events that are imposed entirely by a therapist. By contrast, results of some studies suggest that self-recording, a common component of self-management interventions, might be an effective and efficient way to reduce stereotypy. Because the procedure typically has included instructions to refrain from stereotypy, self-recording of the absence of stereotypy, and differential reinforcement of accurate recording, it is unclear which element or combination of elements produces reductions in stereotypy. We conducted a component analysis of a self-management intervention and observed that decreases in stereotypy might be attributable to instructional control or to differential reinforcement, but that self-recording per se had little effect on stereotypy.  相似文献

We present selected initial results from a study investigating the effects of school restructuring and reform activities on outcomes for students who are identified as having serious emotional and behavioral disabilities. A review of the literature revealed six key areas of reform for investigation: accountability, governance, parent involvement, includedness, curriculum and instruction, and pro-social discipline. Ten schools (five elementary, two K-8, one middle, and two high schools) actively engaged in school restructuring and reform efforts were selected to participate in the study, and their status related to these six areas is presented. Characteristics of the students identified as having emotional and behavioral disabilities and served in these schools in special education settings (N = 116) are described. Results from the administration of standardized assessments revealed that these students have significant levels of emotional and behavioral disabilities that impair their functioning at school and at home. Further, school staff are providing the majority of counseling services to these students during the school day, with non-school professionals providing services to 25% of the students.  相似文献

This experiment assesses spatial and nonspatial relational memory in freely moving 9-mo-old and adult (11-13-yr-old) macaque monkeys (Macaca mulatta). We tested the use of proximal landmarks, two different objects placed at the center of an open-field arena, as conditional cues allowing monkeys to predict the location of food rewards hidden in one of two sets of three distinct locations. Monkeys were tested in two different conditions: (1) when local visual cues marked the two sets of potentially baited locations, so that monkeys could use both local and spatial information to discriminate these locations from never-baited locations; and (2) when no local visual cues marked the two sets of potentially baited locations, so that monkeys had to rely on a spatial relational representation of the environment to discriminate these locations. No 9-mo-old or adult monkey associated the presence of the proximal landmarks, at the center of the arena, with the presence of food in one set of three distinct locations. All monkeys, however, discriminated the potentially baited locations in the presence of local visual cues, thus providing evidence of visual discrimination learning. More importantly, all 9-mo-old monkeys tested discriminated the potentially baited locations in absence of the local visual cues, thus exhibiting evidence of spatial relational learning. These findings indicate that spatial memory processes characterized by a relational representation of the environment are present as early as 9 mo of age in macaque monkeys.  相似文献

In four experiments the effects of serial compound conditioning on responding to a trace-conditioned CS were evaluated using a fear conditioning paradigm. The subjects were 18- and 25-day-old Sprague-Dawley rats, previously shown to exhibit little or no trace fear conditioning. Here, animals as young as 18 days of age were shown to be capable of trace conditioning between a visual CS1 and a shock US, provided the trace interval was filled with a non-target CS2 during serial conditioning trials (CS1-->CS2-->US). To explore cholinergic mechanisms involved in trace and serial conditioning, additional experiments assessed conditioned responding following pre-training administration of the muscarinic receptor antagonist scopolamine. Scopolamine produced a dose-dependent reduction in responding to the trace CS1, regardless of whether subjects were trained with standard trace (CS1-->trace interval-->US) or serial (CS1-->CS2-->US) trials. Responding to CS2 was unaffected by scopolamine. These data suggest that central cholinergic systems are functional in the young animals, but are not normally sufficiently activated by standard trace conditioning procedures. The results suggest that serial compound conditioning can promote trace conditioning in young rats, as it does in adults, perhaps by enhancing cholinergic activity during training. Implications for the late ontogenetic emergence of trace conditioning as it relates to maturation of neural pathways and their role in the potentiating effects of a gap filler are discussed.  相似文献
