Big five dimensions and ADHD symptoms: links between personality traits and clinical symptoms 总被引:8,自引:0,他引:8

Attention-deficit/hyperactivity disorder (ADHD) in adulthood is conceptualized as originating in childhood. Despite considerable theoretical interest, little is known about how ADHD symptoms relate to normal personality traits in adults. In 6 studies, the Big Five personality dimensions were related to ADHD symptoms that adults both recalled from childhood and reported concurrently (total N = 1,620). Substantial effects emerged that were replicated across samples. First, the ADHD symptom cluster of inattention-disorganization was substantially related to low Conscientiousness and, to a lesser extent, Neuroticism. Second, ADHD symptom clusters of hyperactivity-impulsivity and oppositional childhood and adult behaviors were associated with low Agreeableness. Results were replicated with self-reports and observer reports of personality in community and clinical samples. Findings support theoretical connections between personality traits and ADHD symptoms. 相似文献

Four experiments, which examine some functional properties of iconic storage in mildly retarded subjects, are reported. Experiments I and III demonstrated that retardates report about three items, or one item less than normal subjects, after a single brief tachistoscopic exposure and that this span of attention was independent of size of array. Both normal and retarded groups reported more items correctly when arrays were arranged on two lines. Experiment II determined that exposure durations up to 250 msec did not influence the number of items reported by either group. Experiment IV compared the form of decay for both groups by cuing report of each of seven positions at five poststimulus delays. The presence of the typical W-shaped curve for both groups at all delays permitted the inference that items in iconic storage decay together rather than individually. Although quantitative differences existed between groups, in no case did intelligence interact with the manipulated variables. The results were discussed in relation to control processes and structural features within an information processing model of memory. 相似文献

Etiology of Inattention and Hyperactivity/Impulsivity in a Community Sample of Twins with Learning Difficulties 总被引:3,自引:0,他引:3
A community sample of 373 8 to 18 year-old twin pairs in which at least one twin in each pair exhibited a history of learning difficulties was utilized to examine the etiology of inattention and hyperactivity/impulsivity (hyp/imp). Symptoms of attention-deficit/hyperactivity disorder (ADHD) were assessed by the DSM-III Diagnostic Interview for Children and Adolescents. Inattention and hyp/imp composite scores were created based on results of a factor analysis. Results indicated that extreme ADHD scores were almost entirely attributable to genetic influences across several increasingly extreme diagnostic cutoff scores. Extreme inattention scores were also highly heritable whether or not the proband exhibited extreme hyp/imp. In contrast, the heritability of extreme hyp/imp increased as a linear function of the number of inattention symptoms exhibited by the proband. This finding suggests that extreme hyp/imp may be attributable to different etiological influences in individuals with and without extreme inattention. If this result can be replicated in other samples, it would provide evidence that the hyp/imp symptoms exhibited by individuals with Combined Type ADHD and Predominantly Hyp/Imp Type ADHD may be attributable to different etiological influences. 相似文献

The present study is the first to utilize twin modeling to examine whether parent-teacher disagreement for ADHD ratings is
due to parent or teacher bias, or due to raters observing different but valid ADHD behaviors. A joint analysis was conducted
with 106 twin pairs, including twins selected for ADHD and control twin pairs. Total ADHD scores were analyzed using multiple
rater models that estimate genetic and environmental contributions common to both raters and unique to each rater. Results
suggest that 1) disagreement in ADHD ratings is strongly due to parents and teachers observing different ADHD behaviors, some
of which is valid and some of which is due to bias, and 2) parents may be more biased than teachers in their ADHD ratings. 相似文献

Four studies identify and examine a temporal component to regulatory focus. Results support the assertion that promotion focus tends to predominate for temporally distant goals, whereas proximal goals are characterized by more balanced consideration of both promotion- and prevention-focused concerns. In Study 1, students rated the importance of promotion and prevention goals at two points in time: 2 weeks before and a few minutes before an examination. Promotion goal importance increased with temporal distance, whereas prevention goal importance remained constant over time. Study 2 replicated this pattern holding the actual time-span constant (3.5 weeks) and varying only the psychological sense of proximity/distance. In Study 3, subjects rated the regulatory focus of goals at varying points in time, both future and past. The temporal effect was replicated for both time periods. Study 4 provided evidence for the reverse effect, that of regulatory focus on the perceived temporal distance of future goals. Taken together, these findings suggest an integration across research domains that links regulatory focus to temporal perspective for both prospective and retrospective judgments. 相似文献

Typical U.S. children use their knowledge of letters' names to help learn the letters' sounds. They perform better on letter sound tests with letters that have their sounds at the beginnings of their names, such as v, than with letters that have their sounds at the ends of their names, such as m, and letters that do not have their sounds in their names, such as h. We found this same pattern among children with speech sound disorders, children with language impairments as well as speech sound disorders, and children who later developed serious reading problems. Even children who scored at chance on rhyming and sound matching tasks performed better on the letter sound task with letters such as v than with letters such as m and h. Our results suggest that a wide range of children use the names of letters to help learn the sounds and that phonological awareness, as conventionally measured, is not required in order to do so. 相似文献
