In five experiments, we examined task factors influencing selection by color in a rapid serial visual presentation (RSVP) task. Participants were required to respond to the presence or case of a target letter presented within an RSVP sequence, and they were cued as to the color in which that target was most likely to occur. The first two experiments explored the effect of task difficulty. It was found that a change from the discrimination of upper- versus lowercase targets to the detection of an exact shape had no influence on the color-cuing effect. In contrast, increasing letter set discriminability and decreasing color discriminability reduced the color-cuing effect considerably, although they did not eliminate it. In the third and fourth experiments, the frequency of valid trials was reduced, removing the incentive to use the color information. Again, a small benefit remained, indicating partially automatic and strategic color-processing components. Finally, the fifth experiment showed that an increase in perceptual load had no influence on the color-cuing effect. Together, these five experiments provide further evidence of the robustness of direct selection by color. 相似文献

In this paper, we investigate the ability of Dutch agrammatic Broca's and Wernicke's aphasics to assign reference to possessive pronouns in elided VP constructions. The assumption is that the comprehension problems in these two populations have different sources that are revealed in distinct patterns of responses. The focus is primarily on the performance of the agrammatic group whose errors in comprehension are not viewed as a consequence of a breakdown of grammatical knowledge but as a result of limited processing resources (for an overview see Grodzinsky, 2000). The results of the present study provide evidence for the psycholinguistic reality of the economy hierarchy as proposed in the Primitives of Binding (Reuland, 2001). According to the economy hierarchy proposed for the non-brain-damaged, the more economical semantic dependencies are preferred over the costlier discourse dependencies. This hierarchy is reflected in agrammatic aphasia where the semantic dependencies are available on time and preferred over the discourse dependences that are not available on time as a result of the lack of processing resources with consequences for comprehension. 相似文献

We report results of an experimental study with Dutch agrammatic aphasics that investigated their ability to interpret pronominal elements in transitive clauses and Exceptional Case Marking constructions (ECM). Using the obtained experimental results as a tool, we distinguish between three competing linguistic theories that aim at determining principles responsible for pronoun distribution: Government and Binding (Chomsky, 1981), Reflexivity (Reinhart & Reuland, 1993), and Primitives of Binding (Reuland, 2001). The obtained results are inconsistent with Government and Binding, but consistent with the latter two theories. We further show that the Primitives of Binding framework most naturally explains our results. Our proposal is based on the different performance demonstrated by patients in transitive clauses and ECM constructions, in combination with the often-made claim in the literature regarding the limitation of processing resources in this population (e.g., Haarmann and Kolk, 1991, Haarmann and Kolk, 1994 and Zurif et al., 1993, among others). 相似文献

The performance on the Stroop Color-Word Interference Test of 36 boys with Attention Deficit Hyperactivity Disorder (ADHD) was compared with performances of a matched control sample. The control group outperformed their counterparts on the control and interference conditions of the Stroop test, suggesting ADHD-specific executive and reading deficits. When individuals with both ADHD and reading disorders were excluded from the analysis, the authors found a significant difference between the ADHD group and the control group on the color-word test, indicating that poor reading skills may produce false negatives on the Stroop test. However, fast and slow readers with ADHD did not perform differently from each other on the color-word test. The authors postulated the existence of two different causes of reading problems: phonological deficits and attentional deficits. 相似文献

When forgiving enhances psychological well-being: the role of interpersonal commitment 总被引:2,自引:0,他引:2

The present research addresses the question of when and why forgiving might enhance psychological well-being. The authors predict that forgiving is associated with enhanced well-being but that this association should be more pronounced in relationships of strong rather than weak commitment. This hypothesis received good support in Studies 1-3. Studies 2 and 3 addressed the issue of why forgiving might be associated with psychological well-being, revealing that this association was reduced after controlling for psychological tension (i.e., a psychological state of discomfort due to conflicting cognitions and feelings). Study 4 revealed that in the context of marital relationships, tendencies toward forgiving one's spouse exhibited a more pronounced association with psychological well-being than did tendencies to forgive others in general. 相似文献

A social identity approach to the investigation of group-based reactions to a merger is outlined, in which a merger is analyzed in terms of the continuation or change of the pre-merger group identity. In two experiments, the relationship between pre-merger identification, post-merger identification, and ingroup bias was investigated using a minimal group paradigm. Results from both studies showed that the perceived continuation of the pre-merger group identity in the post-merger group strengthened the positive relationship between pre-merger identification and identification with the superordinate post-merger group. Moreover, perceived continuation strengthened, rather than reduced, ingroup bias at the subordinate level of the merged groups. Some theoretical and practical implications are discussed. 相似文献

Increased difficulty with response inhibition occurs with age, although there is some controversy as to whether increased interference on Stroop tasks reflects difficulties with response inhibition or simply reflects generalized cognitive slowing. The Victoria Stroop Test (VST) is a brief, easily administered, psychometrically sound version of Stroop's original task. Performance on the VST by adults across a wide age span was examined to determine the association between age and various measures of interference. In addition, normative data for the VST were calculated. Participants were 272 healthy, community-dwelling adults age 18 to 94. Age and speed were negatively correlated on all trials of the VST. Importantly, however, interference scores that were corrected for baseline slowing remained highly correlated with age. Similarly, age and error scores on the interference trial were positively correlated, indicating decreased accuracy with age. These findings suggest that increased interference on Stroop tasks with age is not accounted for by simple cognitive slowing and more likely reflects other cognitive changes, such as decreased response inhibition. The VST has a number of administrative and psychometric strengths, and the provision of normative data should enhance its potential for clinical and research applications. 相似文献

Widespread dissemination of evidence-based programs for underserved populations may require non-traditional means of service provision. Collaboration with paraprofessionals from communities that are targeted for intervention holds promise as a delivery strategy that may make programs more accessible and acceptable, especially to parents living in low-income, urban neighborhoods. We describe a paraprofessional training program for individuals living in a community targeted for preventive intervention based on high levels of poverty and community violence. The design and implementation of the training program are described in the context of issues related to the use of paraprofessionals in community-based, preventive interventions with parents of young children. We also provide insight into lessons learned from a feasibility study as well as general guidelines for the development of paraprofessional training programs for delivery of evidence-based programs. 相似文献

We describe a university-community collaborative effort to tailor and deliver a prevention program for families of preschoolers living in low-income, urban communities. ParentCorps, which builds on efficacious interventions with parents and young children, aims to promote child social competence and prevent conduct problems by strengthening parenting skills, enhancing support for parents, and empowering parents to access resources in their communities. Active community engagement and collaboration were viewed as critical to the development of the program and its feasibility testing. We present an overview of community involvement in the development of ParentCorps and approaches taken to involve community members during a feasibility study. Areas of success and lessons learned are discussed. 相似文献

The aim of this study was to develop a Self-Talk Inventory for young adults. This inventory consisted of two scales. The Negative Self-Talk Scale included three categories of self-talk (depressive, anxious, and angry thoughts) and the Positive Self-Talk Scale, three categories (minimization, positive orientation, and coping self-instructions). Participants were 982 undergraduate students (Mean age = 20.35 years, SD = 2.16). They completed the self-talk scales together with the following scales to measure symptoms of affective disorders: the Center for Epidemiological Studies Depression Scale (CES-D), the State-Trait Anxiety Inventory (STAI), and the State-Trait Anger Expression Inventory (STAXI-T). Factor analyses confirmed the hypothesized structure for the Self-Talk Inventory. The relations between self-talk and symptoms of affective disorders (depression, anxiety, and anger) were also evaluated. In general, states-of-mind -SOM- ratios and negative cognitions showed a greater association with psychological symptoms than did positive cognitions. Results concerning the cognitive characteristics of depression, anxiety, and anger were mixed and partially supported the cognitive content specificity theory. 相似文献
