Although dependence in effect sizes is ubiquitous, commonly used meta-analytic methods assume independent effect sizes. We describe and illustrate three-level extensions of a mixed effects meta-analytic model that accounts for various sources of dependence within and across studies, because multilevel extensions of meta-analytic models still are not well known. We also present a three-level model for the common case where, within studies, multiple effect sizes are calculated using the same sample. Whereas this approach is relatively simple and does not require imputing values for the unknown sampling covariances, it has hardly been used, and its performance has not been empirically investigated. Therefore, we set up a simulation study, showing that also in this situation, a three-level approach yields valid results: Estimates of the treatment effects and the corresponding standard errors are unbiased. 相似文献

This study evaluated the extent and severity of depressive symptoms among adults (n=1015) in Armenia one year after the 1988 earthquake, using an Armenian translation of the Beck Depression Inventory (BDI-Arm). Earthquake surivivors had higher levels of depression than did their non-earthquake counterparts. For both the quake and non-quake regions, women were found to have higher scores on the BDI-Arm than men, and persons between the ages of 31–55 reported significantly higher depressive ratings than individuals who were 17–30. Interactions between the quake and non-quake areas and gender indicated that women in both areas reported significantly more depressive symptoms than men. The psychometric properties of the BDI-Arm compared favorably to those defined by North American studies. 相似文献

Early risk exposure reportedly influences romantic relationship formation via an increase in sexualized reproductive strategies and attachment insecurity. Because these are risk adaptations that predict differing interactions in romantic relationships and are complexly related to gender, two studies focused on these features in relation to relationship formation in emerging adulthood. Beyond confirming that self-reported early risk exposure was associated with a more sexualized romantic self-concept, greater numbers of relationships, and greater attachment insecurity, “Study 1” confirmed a hypothesized four-way interaction between gender, early risk, romantic self-concept, and attachment style. “Study 2” clarified the interaction through a regression model predicting a sexualized romantic self-concept differently for men and women. A structural equation model including all the study variables confirmed the hypothesis that pathways for men primarily predicted unrestricted sexuality (i.e., numbers of casual relationships), whereas the pathways for women included direct effects from risk and indicators of committed relationships. 相似文献

Offline verbalization about a new motor experience is often assumed to positively influence subsequent performance. Here, we evaluated this presumed positive influence and whether it originates from declarative or from procedural knowledge using the explicit/implicit motor-learning paradigm. To this end, 80 nongolfers learned to perform a golf-putting task with high error rates (i.e., explicit motor learning), and thus relied on declarative knowledge, or low error rates (i.e., implicit motor learning), and thus relied on procedural knowledge. Afterward, they either put their memories of the previous motor experience into words or completed an irrelevant verbal task. Finally, they performed the putting task again. Verbalization did not improve novice motor performance: Putting was impaired, overall, and especially so for high-error learners. We conclude that declarative knowledge is altered by verbalization, whereas procedural knowledge is not. 相似文献

Young adults are more likely to correct an initial higher confidence error than a lower confidence error (Butterfield & Metcalfe, 2001). This hypercorrection effect has never been investigated among older adults, although features of the standard paradigm (free recall, metacognitive judgments) and prior evidence of age-related error resolution deficits (see Clare & Jones, 2008) suggest that they may not show this effect. In Study 1, we used free recall and a 7-point confidence scale; in Study 2, we used multiple-choice questions, and participants indicated how many alternatives they had narrowed their options down to prior to answering. In both studies, younger and older adults showed a hypercorrection effect, and this effect was equivalent between groups in Study 2 when free recall and explicit confidence ratings were not required. These results are consistent with our previous work (Cyr & Anderson, 2012) showing that older adults can successfully resolve learning errors when the learning context provides sufficient support. 相似文献

This article proposes the Charcot effect, in which clinicians describe what they themselves prescribe. It is argued that the Charcot effect can be a critical instrument for exposing how mental illnesses are invented in the process of developing diagnostic systems and conducting psychopharmacological research. We argue that the Charcot effect helps explain the expansion of depression to epidemic proportions, the promotion of social phobia as a pharmaceutical marketing strategy, the profile of panic disorder according to the available medication, and the worse prognosis of schizophrenia in developed countries than in developing countries. Having undertaken this review, we situate the Charcot effect in relation to constructivist psychology. 相似文献

The purpose of this study is to offer a model in which auditory verbal hallucinations (AVHs) can be conceptualized as dialogical experiences. This model is of interest in that it integrates several different perspectives (phenomenological, cognitive, social, and evolutionary) and the findings of empirical research on the subject. Hallucinations are understood as the product of a state of consciousness in which the self is dissociated into different positions or perspectives. After reviewing the most relevant results of psychological research, dialogical self theory is proposed as the theoretical framework for understanding hallucinatory experiences. It is argued that the voices possess a series of characteristics, pragmatic properties, relationships with the voices similar to their social surroundings, and more dissociative experiences in people who experience voices than in those who do not, with which they may be considered a dialogical experience. Finally, a model attempting to integrate psychological research on AVHs within the framework of dialogical self theory is presented. 相似文献

The tendency of participants to “remember” the stopping point of an event as being farther along in the direction of motion has been a topic of study for about 30 years. The purpose of the present experiment was to test the influence of two factors on motion extrapolation: (1) The involvement of participants in the action, and (2) their expertise in the domain of automobile driving. Participants viewed real driving scenes from the driver's point of view. They were divided into four groups depending upon their involvement in the action (more or less active) and their driving experience (inexperienced or experienced). In order to get half of the participants involved in the driving situation, they had to use a steering wheel to follow the contour of the road. The results showed that both of these factors increased motion extrapolation. The discussion deals with how the interrelationships between real road scenes, expertise, and action-related knowledge affect motion extrapolation. 相似文献

Navigation through the environment requires the brain to process a number of incoming sensory signals, such as visual optical flow on the retina and motion information originating from the vestibular organs. In addition, tactile as well as auditory signals can help to disambiguate the continuous stream of incoming information and determining the signals resulting from one's own set of motion. In this review I will focus on the cortical processing of motion information in one subregion of the posterior parietal cortex, i.e., the ventral intraparietal area (VIP). I will review (1) electrophysiological data from single cell recordings in the awake macaque showing how self‐motion signals across different sensory modalities are represented within this area and (2) data from fMRI recordings in normal human subjects providing evidence for the existence of a functionally equivalent area of macaque area VIP in the human cortex. 相似文献

A study in Singapore (Ang et al., 2003) found that foreign employees displayed a lower tendency to engage in Organizational Citizenship Behaviour (OCB) than their local counterparts. The explanation was that foreign employees often experience their employment relation as more disadvantageous. The present study attempted to investigate possible differences in OCB between foreign and local workers in The Netherlands. In addition, it aimed to ascertain what role the cultural dimension of “individualism–collectivism” plays in this connection. Contrasting the expectations, the foreign employees reported a higher propensity to pursue OCB than local workers. The difference in behaviour could not be explained by cultural differences. It was argued that economic and personal motives of foreign workers might have affected the self-reports of their organizational behaviour. 相似文献
