目标对决策的影响过程包含了明晰目标的决策过程和在目标的动机作用下完成后续决策任务的过程。目标是个体期望实现的多个未来结果相互之间竞争动机作用的结果。依据对未来结果的渴望性和可行性等特征的认知, 个体抉择出某个未来结果作为自己的目标, 使其具有了动机作用。在明晰目标的过程中, 解释水平、自我控制的人格特质和成功经验都会产生重要影响。在明确了目标以后, 目标通过改变个体对有利于目标实现的决策备择方案的态度和选择性注意来影响个体的决策。未来研究可以从目标的意识程度对决策负面结果的影响, 对决策的心理过程进行直接测量等角度来探讨目标对决策的影响。 相似文献

职业决策对大学生职业生涯发展具有重要意义。心理距离作为个体决策的重要影响因素之一,是否也影响着大学生的职业决策偏好?研究通过4个实验,采用2(心理距离:远、近)*2(性别:男、女)混合实验设计,以大学生为研究对象,探讨了心理距离(空间距离、时间距离、社会距离、假设性)和性别对职业决策偏好的影响。研究发现:(1)大学生在心理距离远的情境下更偏好选择稳定、职业声望高的职业;在心理距离近的情境下更偏好选择薪资高、专业对口的职业。(2)空间距离、时间距离、社会距离近的情境下,男大学生比女大学生更偏好选择薪资高、专业对口的职业。 相似文献

本研究采用联结再认范式考察联结记忆中感知觉水平和概念加工程度对图片优势效应的影响。实验1通过呈现清晰或模糊的词语或图片对操纵了感知觉水平,结果发现只有在清晰条件下图片优势效应才会出现;实验2则在模糊条件下通过要求被试想象两个项目之间的关系操纵了概念加工程度,结果发现在有概念加工条件下,出现了图片优势效应。研究结果表明:(1)降低的感知觉水平会导致联结记忆中的图片优势效应消失;(2)对模糊项目对进行概念加工会使联结记忆中出现图片优势效应。 相似文献

The multidimensional nature of the frontal lobes serves to organize and coordinate brain functionings playing a central and pervasive role in human cognition. The executive processes implicated in complex cognition such as novel problem solving, modifying behavior as appropriate in response to changes in the environment, inhibiting prepotent or previous responses, and the implementation of schemas that organize behavior over time are believed to be mediated by the frontal regions of the brain. Overall, the functioning of the frontal lobes assists individuals in goal directed and self-regulatory behavior. Additional theories of frontal lobe functioning have focused on its involvement in temporal, or time-related domains. The organizational and strategic nature of frontal lobe functioning affects memory processes by enhancing the organization of to-be-remembered information. Among the specific memory systems presumed to be based on anterior cerebral structures is the temporal organization of memory. An essential component of memory that involves temporal organization is sequential ordering entailing the ability to judge which stimuli were seen most recently and the temporal ordering of events in memory. Focal lesion studies have demonstrated the importance of the frontal lobes on retrieval tasks in which monitoring, verification, and placement of information in temporal and spatial contexts of critical importance. Similarly, frontal lobe damage has been associated with deficits in memory for the temporal ordering, or sequencing, of events. The acquisition of abilities thought to be mediated by the frontal lobes, including sequential memory, unfolds throughout childhood, serving to condition patterns of behavior for the rest of the brain. Development of the frontal regions of the brain is known to continue through late adolescence and into early adulthood, in contrast to the earlier maturation of other cortical regions. The developmental patterns of the frontal lobes are thought to involve a hierarchical, dynamic, and multistage process. 相似文献

We administered the Tower of Hanoi to demographically comparable samples of control participants (n = 34) and children with the Combined (n = 22) and Inattentive subtypes (n = 19) of Attention-Deficit/Hyperactivity Disorder (ADHD). Controls excelled over children with the Inattentive subtype, who
outperformed patients with the Combined subtype. These results replicated findings of greater executive deficits in the Combined
than in the Inattentive type of ADHD. Double-blind administration of methylphenidate improved task performance only for patients
with the Inattentive subtype. In a drug-free Baseline session, children with both subtypes of ADHD made more private verbalizations
than controls, particularly when failing puzzles. In later sessions, regardless of drug condition, the inattentive sample
exhibited a smaller increase in self-regulatory utterances under failure. In contrast, the combined sample decreased self-regulatory
verbalizations under failure only under methylphenidate. The results support some differences between the two subtypes of
ADHD in executive functioning and in their response to stimulant therapy.
Portions of these results were submitted as part of H. Theresa Chang's PhD dissertation (Chang, 2000) and Helena Kopecky's
unpublished master's research, both conducted at the University of Rochester and supervised by Rafael Klorman. 相似文献

Peer problems are almost universal among children with disruptive behavior disorders, and have been linked to social information processing deficits that lead to heightened threat responses (K. A. Dodge, 1980). This 2-year longitudinal study uses direct observations to examine the real-life significance of this finding. Forty hard-to-manage children and 40 typically developing control children were filmed at ages 5 and 7 playing a rigged competitive game in which they experienced a clear threat of losing. Group differences in negative behavior (hard-to-manage > controls) were stable over time and independent of verbal ability. Predictors of individual differences in negative behavior were also examined. Previous studies with this sample have shown that at 4 years of age, the hard-to-manage children displayed elevated frequencies of violent pretend play (J. Dunn & C. Hughes, 2001), coupled with poor performance on tests of executive function and theory of mind (C. Hughes, J. Dunn, & A. White, 1998). In this study, 4-year-olds whose pretend play indicated a preoccupation with violence were more likely to respond negatively to the threat of losing a competitive game at age 5 and at age 7. Four-year-olds who performed poorly on tests of theory of mind and executive function showed higher rates of negative behavior at age 5 but not age 7. These findings highlight just a few of the multiple paths leading to peer problems among children with disruptive behavior problems. 相似文献

The purpose of this study was to examine the additional benefit of an adaptive Cogmed working memory training (CWMT) to a social-emotional/self-regulation classroom curriculum for preschoolers with externalizing behavior problems (EBP). Participants for this study included 49 children (71% boys, Mage = 4.52) with at-risk or clinically elevated levels of EBP. Children participated in an 8-week summer treatment program for Pre-Kindergarteners (STP-PreK), where they were randomly assigned to either adaptive CWMT (n = 24), or nonadaptive CWMT (n = 25). Multiple repeated measures analyses were conducted to examine the impact of adaptive versus nonadaptive CWMT on pre and posttreatment parent-/teacher-reported behavioral functioning, parent-/teacher reported and child task performance of executive functioning, and standardized academic achievement measures. Repeated measures analyses found that children in both groups improved on all measures (d’s = .23-.86). However, there were no significant time X condition effects for parent or teacher-reported behavior, reported or observed executive functioning, or standardized academic measures. These findings suggest that CWMT does not appear to provide any incremental benefits to children’s executive functioning, behavior, or academics when implemented within a comprehensive behavioral modification intervention. 相似文献

The ability of perspective taking is a fundamental aspect of social cognition. The ability to decide, what another person can or cannot see is referred to as “level 1 perspective taking.” This is thought to be a process that we can make use of intentionally, but which also takes place spontaneously. Autism is characterized by impairments of social interaction, which are thought to be related to deficits in implicit rather than explicit perspective taking. In order to assess both levels of processing with regard to perspective taking, we employed an established task in patients and controls. Our results demonstrate that both groups engage in spontaneous level 1 perspective taking. In contrast to controls, however, patients reacted more slowly if they had to verify the other’s as compared to their own perspective, which shows that participants with high-functioning autism have selective difficulties in explicit, but not implicit, level 1 perspective taking. These findings demonstrate that while spontaneous level 1 perspective taking appears to be intact in autism, this ability is impaired in patients when used explicitly. 相似文献
