Literature on multivariable causal inference (MCI) and literature on scientific reasoning (SR) have proceeded almost entirely independently, although they in large part address the same phenomena. An effort is made to bring these paradigms into close enough alignment with one another to compare implications of the two lines of work and examine how they might illuminate one another. The conclusion is that SR research stands to benefit from recognition that it addresses a broader set of cognitive phenomena than reasoning in contexts that are explicitly scientific, whereas MCI research stands to benefit from recognizing inter- and, especially, intra-individual variability that its methods may have masked. Data reported here based on a merging of the two methodological paradigms support a model in which individuals have available a repertory of different inference strategies or rules (reflecting different criteria for inferences of causality) from which they select variably across occasions, in a dynamic process of theory-evidence coordination. 相似文献

The generation effect involves an improvement in memory when learners must complete or modify materials. Several researchers have suggested that this effect involves enhanced access to learners' existing memory representations; therefore, the effect should be less effective with meaningless, low meaningful, or unfamiliar material. In the present study, the authors conducted 4 experiments in which legal nonwords were used, and they found no generation effect. In another 2 experiments in which familiar clichés were contrasted with new sentences and with unfamiliar sentences from textbooks, the results showed a greatly reduced generation effect for the new, unfamiliar material. Those findings suggest that memory strategies that depend on the generation effect will have limited effectiveness when they are applied to new or unfamiliar material. 相似文献

Methodologists have developed mediation analysis techniques for a broad range of substantive applications, yet methods for estimating mediating mechanisms with missing data have been understudied. This study outlined a general Bayesian missing data handling approach that can accommodate mediation analyses with any number of manifest variables. Computer simulation studies showed that the Bayesian approach produced frequentist coverage rates and power estimates that were comparable to those of maximum likelihood with the bias-corrected bootstrap. We share an SAS macro that implements Bayesian estimation and use 2 data analysis examples to demonstrate its use. 相似文献

This article discusses the application in a CAMHS setting of a distinctive intervention for adolescent mental health difficulties, time-limited adolescent psychodynamic psychotherapy (TAPP). TAPP has been developed specifically for working with adolescents and the characteristic developmental and psychosocial complexities they present to mental health services. It is widely recognised that supporting the developmental process in adolescence is central to therapeutic interventions and the therapeutic aim of TAPP is to enable recovery of the capacity to meet developmental challenges. The key factors of TAPP are described, including the formulation and working with a developmental focus, the therapeutic stance, working with transference and counter-transference, working with time limits, and the emphasis is placed on engagement of adolescents in therapy in TAPP. The experiences of introducing and developing TAPP in the CAMHS service are discussed with two brief and one extended case examples and this leads to a discussion of the kinds of outcomes achieved. It is concluded that TAPP is a key and relevant intervention for adolescents in complex and vulnerable situations; further work will be undertaken to continue its application in these settings and to formally assess outcomes. 相似文献

Participants viewed video clips of a left or right-handed reach toward an object that was orientated with a handle to the left or right. They were required to classify the object by making a left or right-handed key-press and ignore the reach. These responses were, never-the-less, affected by the observed reach in ways which largely reflected the opportunities for complementary actions in the viewed scenes, given the simultaneous constraints of the object orientation combined with the direction and hand of reach. These influences are claimed to reflect the interdependency of the action possibilities that arise from a set of objects and agents in three-dimensional space that together determine behaviour. 相似文献

Past research provides conflicting evidence regarding whether aggressive youth have problems in the domain of friendship. The current study tested whether being disliked by peers exacerbates the negative effects of aggression on friendship and whether being perceived as popular by peers mitigates these damaging effects. Participants were 607 third-, fifth-, seventh-, and ninth-grade students. Support for the hypothesis that being disliked or being perceived as popular would moderate relations between aggression and friendship adjustment was found for the association between relational aggression and friendship conflict. Specifically, relational aggression was associated with having conflictual friendships for youth who were disliked but not for youth who were perceived as popular. In addition, similarity between friends was found in terms of how aggressive youth were as well as in terms of how disliked they were and how popular they were perceived to be. Implications for the well-being and development of aggressive youth are discussed. 相似文献

The psychological approach to human voluntary movements advocated by F. Mechsner (2004) can be aligned with the view that motor commands are generated afresh but are not retrieved from memory. This movement-generation hypothesis gains indirect support in the findings Mechsner reviewed and obtains more direct support from the results of studies of memory for movement and computational modeling of motor planning. 相似文献

The influence of structure and age on sequence learning was investigated by testing 24 young and 24 older participants for 10 sessions in an alternating serial response time task in which pattern trials alternated with random trials. Individuals encountered lag-2 or lag-3 structure, and learning was measured by the difference (in response time and accuracy) between pattern and random trials. Both ages learned lag-2 structure, but the young learned more than the older participants. Only the young people learned lag-3 structure, and they did so more slowly and to a lesser degree than they learned lag-2 structure. These age deficits in higher order sequence learning after extended practice are consistent with simultaneity theory and with theories positing that age-related deficits in neuromodulation lead to less distinctive representations. 相似文献

The relationship of neuropsychological measures of frontal lobe function to age differences in false recall was assessed using the Deese/Roediger-McDermott associative false memory paradigm (Deese, 1959; Roediger & McDermott, 1995). As other studies have found, older adults were less likely to correctly recall studied items and more likely to falsely recall highly related but nonpresented items than were younger adults. When older adults were divided based on a composite measure of frontal lobe functioning, this age difference was found only for low frontal lobe functioning individuals. High frontal lobe functioning older adults and young adults had equivalent levels of false recall, as well as equivalent levels of veridical recall. These results suggest that age differences in memory may be due to declines in frontal lobe function. More important, our findings indicate that declines in veridical recall and increases in false recall are not an inevitable consequence of aging. 相似文献
