This study evaluated the effectiveness of fine motor physical activity with tactile stimulation during two conditions of math
problem solving, visual and auditory. Eight 4th and 5th grade students with attention problems participated. Using an alternating
treatments design, students solved as many math story problems as they could, presented on worksheets or verbally during two
conditions, with and without tactile stimulation during 20 min. Motor behavior, recorded from videotape, and number of correctly
completed word problems were measured. Results suggest that fine motor manipulation of a tactile stimulation object reduced
excessive motor movement and increased task completion of students with attention problems. 相似文献

Midlife decline in declarative memory consolidation is correlated with a decline in slow wave sleep 总被引:3,自引:0,他引:3 下载免费PDF全文

Sleep architecture as well as memory function are strongly age dependent. Slow wave sleep (SWS), in particular, decreases dramatically with increasing age, starting already beyond the age of 30. SWS normally predominates during early nocturnal sleep and is implicated in declarative memory consolidation. However, the consequences of changes in sleep across the life span for sleep-associated memory consolidation have not been evaluated so far. Here, we compared declarative memory consolidation (for word-pair associates) during sleep in young and middle-aged healthy humans. The age groups (18–25 vs. 48–55 yr) did not differ with regard to learning performance before retention periods that covered, respectively, the first and second half of nocturnal sleep. However, after early retention sleep, where the younger subjects showed distinctly more SWS than the middle-aged (62.3 ± 3.7 min vs. 18.4 ± 7.2 min, P < 0.001), retrieval of the word pairs in the middle-aged was clearly worse than in the young (P < 0.001). In contrast, declarative memory retention did not differ between groups after late sleep, where retention was generally worse than after early sleep (P = 0.005). Retention of declarative memories was the same in both age groups when sleep periods containing equal amounts of SWS were compared, i.e., across late sleep in the young and across early sleep in the middle-aged. Our results indicate a decline in sleep-associated declarative memory consolidation that develops already during midlife and is associated with a decrease in early nocturnal SWS. 相似文献

How accurate are self-estimates of cognitive abilities? An investigation of self-estimates of verbal, math, and spatial abilities is reported with a battery of parallel objective tests of abilities. Self-estimates were obtained prior to and after objective ability testing (without test feedback) in order to examine whether self-estimates change after direct objective testing experience. Self-estimates showed small to large effect-size correlations with objective tests--larger for math and smaller for verbal. The construct space of self-estimates of abilities was explored in the context of self-concept, self-esteem, self-efficacy, personality, interests, motivational traits, and trait complexes. Self-efficacy and self-esteem variables showed the highest correlations with self-estimates of abilities. In general, trait complexes showed the highest correlations with verbal ability self-estimates and the lowest correlations with math ability self-estimates. Results are discussed in relation to the principle of aggregation, the influences of self-evaluative judgments, and uses for self-estimates of abilities measures. 相似文献

Previous research has demonstrated that judgmental anchoring effects—the assimilation of a numeric estimate to a previously considered standard—are semantic in nature. They result because the semantic knowledge about the target object that is activated during the comparison with the anchor influences the absolute judgment. In addition to this semantic influence, the numeric anchor value itself may also yield an effect under specific conditions. The present research was designed to examine the relative strength of both mechanisms and explore their boundary conditions. Studies 1 and 2 demonstrate that semantic anchoring effects are more potent than purely numeric effects. Study 3 further suggests that purely numeric effects only operate if accessible semantic knowledge is inapplicable to the critical judgment so that semantic influences are incapacitated. The implications of these findings are discussed from the perspective of an integrative model which differentiates between two stages of anchoring. Whereas purely numeric influences appear to be limited to the stage of anchor selection, the actual comparison with the target involves more elaborate semantic processes. 相似文献

An evaluation of increased response effort to dispose of items was conducted to improve recycling at a university. Signs prompting individuals to recycle and notifying them of the location of trash and recycling receptacles were posted in each phase. During the intervention, trashcans were removed from the classrooms, and one large trashcan was available in the hallway next to the recycling receptacles. Results showed that correct recycling increased, and trash left in classrooms increased initially during the second intervention phase before returning to baseline levels. 相似文献

Noncontingent reinforcement without extinction plus differential reinforcement of alternative behavior during treatment of problem behavior 下载免费PDF全文

The effects of noncontingent reinforcement (NCR) without extinction during treatment of problem behavior maintained by social positive reinforcement were evaluated for five individuals diagnosed with autism spectrum disorder. A continuous NCR schedule was gradually thinned to a fixed‐time 5‐min schedule. If problem behavior increased during NCR schedule thinning, a continuous NCR schedule was reinstated and NCR schedule thinning was repeated with differential reinforcement of alternative behavior (DRA) included. Results showed an immediate decrease in all participants’ problem behavior during continuous NCR, and problem behavior maintained at low levels during NCR schedule thinning for three participants. Problem behavior increased and maintained at higher rates during NCR schedule thinning for two other participants; however, the addition of DRA to the intervention resulted in decreased problem behavior and increased mands. 相似文献

Goffman described the moral career of stigmatized persons as a process by which an individual acquires a stigmatized identity. His analysis, which assumes that individuals recognize and adopt the normative framing of their behavior, glosses over individual identity negotiations. Drawing on 50 interviews with sex industry third parties, this article examines stereotype consciousness—defined as the interactional processes that lead individuals to recognize that they have a discreditable identity. We explore how participants negotiate their identities in response to the social and legal constructions of pimps, procurers, and traffickers, and examine their resistance to the stigmatizing stereotypes that characterize their work. 相似文献

Depression has been reported to be associated with a greater risk of death and cardiovascular disease (CVD); however, the impact of antidepressants (ADM) on CVD risk remains controversial. Statin use is known to decrease CVD risk. Whether the use of these medications together affects CVD risk has not been studied. Patients (N = 26,828) completing the patient health questionnaire (PHQ-9), ≥40 years of age, without prior CVD, and no prior ADM use were studied. Depressive severity was categorized as none-mild (PHQ-9 score ≤14, n = 21,517) and moderate-severe (PHQ-9 score ≥15, n = 5311). Cox hazard regression was used to evaluate the association of no ADM/no statin use (n = 23,104 [86.1%]), ADM/no statin use (n = 877 [3.3%]), no ADM/statin use (n = 2627 [9.8%]), and ADM/statin use (n = 220 [.8%]) with major adverse cardiovascular events (MACE: death, CAD, stroke). Patients averaged 56 ± 12 years; 61% female. There were 1182 (4.4%) 3 year MACE events. The association of ADM and statin use with MACE varied by depressive symptom severity, with statin therapy associated with a decreased risk in the none-mild group (HR = .78, p = .007) and ADM in the moderate-high group (HR = 0.58, p = 0.02). Concomitant use of ADMs and statins did not appear to provide additive benefit. 相似文献

Intimate partner violence (IPV) among African Americans is a serious public health concern. Research suggest that African Americans adolescents, particularly those from economically disadvantaged communities, are at heightened risk for experiencing and perpetrating dating violence compared to youth from other racial and ethnic groups. In the present study, we examined different relationship contexts that are sources of IPV socialization. Semi-structured interviews were conducted with 22 economically disadvantaged African American adolescents. Content analysis yielded five relationship contexts through which the participants witnessed, experienced, and perpetrated IPV: (a) adolescents’ own dating relationships (64%), (b) siblings and extended family members (e.g., cousins, aunts, uncles) (59%), (c) parent-partners (27%), (d) friends (23%), and (e) neighbors (18%). Adolescents also frequently described IPV in their own dating relationships and in parent-partner relationships as mutual. Moreover, they appeared to minimize the experience of IPV in their own relationships. Efforts to reduce rates of IPV among economically disadvantaged African American adolescents should consider these relational contexts through which adolescents are socialized with regards to IPV and adolescents’ beliefs about mutual violence in relationships. Results highlight the importance of culturally relevant prevention and intervention programs that consider these relationship contexts. 相似文献
