Iacobucci (2012) provides a conceptually appealing, readily implemented measure to assess mediation for a far wider range of data type combinations than traditional OLS-based analyses permit. Here, we consider potential applications and extensions along several lines, particularly in terms of random utility models, simulation-based estimation, and potential nonlinearities, as well as some methodological and cultural impediments. 相似文献

Numerous studies have indicated that maintaining a fear memory after retrieval requires de novo protein synthesis. However, no study to date has examined how the temporal dynamics of repeated retrieval events affect this protein synthesis requirement. The present study varied the timing of a second retrieval of an established auditory fear memory and followed this second retrieval with infusions of the protein synthesis inhibitor anisomycin (ANI) into the basolateral amygdala. Results indicated that the memory-impairing effects of ANI were not observed when the second retrieval occurred soon after the first (within 1 h), and that the inhibitor gradually regained effectiveness as the retrieval episodes were spaced further apart. Additionally, if the second of the closely timed retrievals was omitted prior to ANI infusions, long-term memory deficits were observed, suggesting that the altered effectiveness of ANI was due specifically to the second retrieval event. Further experiments revealed that the second retrieval was not associated with a change in Zif268 protein expression but did produce a rapid and persistent dephosphorylation of GluR1 receptors at Ser845, an AMPAR trafficking site known to regulate the stability of GluR2 lacking AMPARs, which have been shown to be important in memory updating. This suggests that the precise timing of multiple CS presentations during the reconsolidation window may affect the destabilization state of the memory trace. 相似文献

AbstractSales representative motivation, satisfaction, and performance have been topics of considerable interest to managers and researchers alike for many years. Recently researchers have borrowed conceptualizations from organizational behavior and applied them successfully in the sales setting. For the most part, research on work-related sales representative motivation has focused on either the “expectancy” approach or the “job characteristics” approach. A brief overview is presented, followed by an assessment of the validity of the core dimensions found in the increasingly popular Job Diagnostic Survey in a sales representative context. The managerial implications of the assessment are also discussed. 相似文献

Abstract When the phenomenological method is applied to mental phenomena their object aspect becomes apparent in a way that contrasts with their meaning aspect. William James described this objective aspect of mental life as early as 1904, but it seems to have been overlooked as an approach to psychopathology. In stepping outside of the natural attitude and directly viewing psychopathology, a hidden, “tangible,” element of inner turmoil is disclosed that is described here as a Phenomenologically Observable Dictate or POD. The technique for dealing with PODs is described. The author claims that the technique opens new avenues of access to some forms of psychopathology, although it does not consist of a complete therapy unto itself. 相似文献

We conducted a meta-analysis of research on hindsight bias to gain an up-to-date summary of the overall strength of hindsight effects and to test hypotheses about potential moderators of hindsight distortion. A total of 95 studies (83 published and 12 unpublished) were included, and 252 independent effect sizes were coded for moderator variables in 3 broad categories involving characteristics of the study, of measurement, and of the experimental manipulation. When excluding missing effect sizes, the overall mean effect size was Md = .39 with a 95% confidence interval of .36 to .42. Five main findings emerged: (a) effect sizes calculated from objective probability estimates were larger than effect sizes calculated from subjective probability estimates; (b) effect sizes of studies that used almanac questions were larger than effect sizes of studies that used real-world events or case histories; (c) studies that included neutral outcomes resulted in larger effect sizes than studies that used positive or negative outcomes; (d) studies that included manipulations to increase hindsight bias resulted in significantly larger effect sizes than studies in which there were no manipulations to reduce or increase hindsight bias; and (e) studies that included manipulations to reduce hindsight bias did not produce lower effect sizes. These findings contribute to our understanding of hindsight bias by updating the state of knowledge, widening the range of known moderator variables, identifying factors that may activate different mediating processes, and highlighting critical gaps in the research literature. 相似文献

Abstract This study was aimed at developing a measure of Kelly's concept of dispersion of dependency and providing evidence for its usefulness in differentiating degree of dispersion of dependency. Smith and Grassle's (1977) adaptation of Hurlbert's diversity index, a measure used by biologists to differentiate degrees of species diversity, was applied to dependency grids, specifically “being helped” grids. The diversity index was shown to be both useful in differentiating prototypes of relatively dispersed and undispersed grids and robust. Furthermore, evidence was provided for its predictive validity using predictions made by Kelly concerning dependency construing associated with differences in dispersion of dependency. Greater dispersion of dependency was related to making more discriminations about dependencies, and undispersed dependency was related to relatively impermeable and preemptive construing. Thus the measure was shown to be satisfactory for identifying dispersion of dependency, such that, used in this context, it could be aptly renamed the dispersion of dependency index. 相似文献

Previous research suggests that child maltreatment is transmitted across familial generations. However, extant studies focused exclusively on single maltreatment subtypes, instead of the more common experience of multitype maltreatment. This limitation is addressed in the first known study to examine the maternal intergenerational transmission of childhood multitype maltreatment among 104 mothers and their children. Findings demonstrated that mothers' childhood multitype maltreatment directly predicted their children's multitype maltreatment, instead of having indirect effects through maternal romantic attachment dimension, intimate partner violence, and psychological distress. Mothers' childhood multitype maltreatment was also related to intimate partner violence and anxious romantic attachment but unrelated to psychological distress. Our findings highlight the need for clinical attention to the long-term generational effects of diverse childhood traumas. 相似文献

Exemplification can be found in ontologies from the ancient world, such as those of Plato and Aristotle, and more recent ontologies, in particular those that take what exists to be determined by the empiricist’s Principle of Acquaintance. This study examines some of the ways in which exemplification takes different forms in these different ontologies. Exemplification has also been criticized as an ontological category. This paper examines a number of these criticisms, to see the extent to which they are viable. 相似文献

ABSTRACT Young and older adults performed verbal and spatial storage-only and storage-plus-processing working memory tasks while performing a secondary finger tapping task, and the effects on both the maximum capacity (measured as the longest series correct) and the reliability (measured as the proportion of items correct) of working memory were assessed. Tapping tended to produce greater disruption of working memory tasks that place greater demands on executive processes (i.e., storage-plus-processing tasks compared to storage-only span tasks). Moreover, tapping produced domain-general interference, disrupting both verbal and spatial working memory, providing further support for the idea that tapping interferes with the executive component of the working memory system, rather than domain-specific maintenance processes. Nevertheless, tapping generally produced equivalent interference effects in young and older adults. Taken together, these findings are inconsistent with the hypothesis that age-related declines in working memory are primarily attributable to a deficit in the executive component. 相似文献
