Advancing Uncertainty: Untangling and Discerning Related Concepts

Janice Penrod
2002 International Journal of Qualitative Methods  
Through concept analysis, the concept was deconstructed to identify conceptual components and gaps in understanding.  ...  In this section, I describe methodological perspectives of a project designed to advance the concept of uncertainty using multiple qualitative methods.  ...  Thus, this project of advancing the concept of uncertainty produced a more coherent concept of broader scope in a manner that addressed a significant threat to validity: conceptual tunnel vision.  ...

Review of Experimental and Quasi-experimental Designs for Generalized Causal Inference

G Julnes
2004 Evaluation and Program Planning  
In this view, as Campbell (1986) put it, you add a placebo control to address construct validity, not internal validity.  ...  In sum, one does not add a placebo control simply to enhance construct validity but rather to address also internal validity on a more molecular level.  ...

Campbell's and Rubin's perspectives on causal inference

Stephen G. West, Felix Thoemmes
2010 Psychological methods  
The authors highlight dimensions on which the 2 approaches have different emphases, including the roles of constructs versus operations, threats to validity versus assumptions, methods of addressing threats  ...  Campbell's approach focuses on the identification of threats to validity and the inclusion of design features that may prevent those threats from occurring or render them implausible.  ...  The typical threats to a design may not be plausible in a specific research area. Addressing threats to internal validity: Design elements.  ...

Further Validation of Measures of Target Detection and Stereotype Activation in the Stereotype Misperception Task

Regina Reichardt, Andrew M. Rivers, Joerg Reichardt, Jeffrey W. Sherman
2020 Frontiers in Psychology  
To this end, the data from Experiment 2 and Experiment 4 in Krieglmeyer and Sherman (2012) were re-analyzed using a bootstrap method to investigate the robustness of the results.  ...  Previous research presented a multinomial model to estimate four latent processes (target detection, stereotype activation, stereotype application, guessing) that contribute to responses in the Stereotype  ...  ACKNOWLEDGMENTS We thank Karl Christoph Klauer for the suggestion to conduct bootstrap analyses.  ...
