Using cognitive learning theory to design effective on-line statistics tutorials

Careful attention to principles of learning can improve the design of Web-based lessons and tutorials. Tutorials from the Web Interface for Statistics Education (WISE; http://wise.cgu.edu) demonstrate how specific principles can be integrated into Web design to enhance learning in two areas. First, the impact of students’ poor self-regulation abilities on Web-based learning is considered. Second, evidence that specific types of visual presentations improve learning is discussed. Finally, the need for empirical evaluation is emphasized. Specific research and examples from the WISE project are used to illustrate each of these points.     

The Influence of the BDNF Val66Met Polymorphism on Mechanisms of Semantic Priming: Analyses with Drift-Diffusion Models of Masked and Unmasked Priming

Automatic and strategic processes in semantic priming can be investigated with masked and unmasked priming tasks. Unmasked priming is thought to enable strategic processes due to the conscious processing of primes, while masked priming exclusively depends on automatic processes due to the invisibility of the prime. Besides task properties, interindividual differences may alter priming effects. In a recent study, masked and unmasked priming based on mean response time (RT) and error rate (ER) differed as a function of the BDNF Val66Met polymorphism (Sanwald et al., 2020). The BDNF Val66Met polymorphism is related to the integrity of several cognitive executive functions and might thus influence the magnitude of priming. In the present study, we reanalyzed this data with drift-diffusion models. Drift-diffusion models conjointly analyze single trial RT and ER data and serve as a framework to elucidate cognitive processes underlying priming. Masked and unmasked priming effects were observed for the drift rates ν, presumably reflecting semantic preactivation. Priming effects on nondecision time t0 were especially pronounced in unmasked priming, suggesting additional conscious processes to be involved in the t0 modulation. Priming effects on the decision thresholds a may reflect a speed-accuracy tradeoff. Considering the BDNF Val66Met polymorphism, we found lowered drift rates and decision thresholds for Met allele carriers, possibly reflecting a superficial processing style in Met allele carriers. The present study shows that differences in cognitive tasks between genetic groups can be elucidated using drift-diffusion modeling.     

Perceptual consciousness plays no epistemic role

It is often assumed that perceptual experience provides evidence about the external world. But much perception can occur unconsciously, as in cases of masked priming or blindsight. Does unconscious perception provide evidence as well? Many theorists maintain that it cannot, holding that perceptual experience provides evidence in virtue of its conscious character. Against such views, I challenge here both the necessity and, perhaps more controversially, the sufficiency of consciousness for perception to provide evidence about the external world. In addition to motivating and defending the idea that unconscious perception can and does often provide evidence, I observe that whether or not perceptual phenomenology is relevant to the evidentiary status of perception depends on the nature of consciousness. And I argue that a well‐supported theory of consciousness—higher‐order thought theory—invites a striking conclusion: that perceptual phenomenology is not on its own sufficient to provide for evidence of the external world.

Perceptions of informal sanctioning and the stigma of involuntary childlessness

This study systematically examines the role of informal social response in the emergence of involuntary childlessness or infertility as a stigmatizing attribute. Seventy‐one involuntarily childless women provide detailed instances of perceived informal social sanctions related to their infertility. Subjects perceive that normals consider infertility to be caused by psychological or sexual malfunctioning, or by the woman in the dyad. Infertility is also seen by some to act as a master status. Subjects categorize other infertile individuals in terms of stigma and consider male infertility to be more stigmatizing than female infertility. Social sanctions and social control are shown to be relevant to an understanding of the experience of involuntary childlessness.     

A Place at the Table: Integrating Diet and Nutrition into Family Therapy Practice

Most schools of family therapy directly or indirectly recognize that personal qualities of the therapist influence therapy process. If personal qualities of therapists are associated with therapy process, it seems plausible that there would be some interaction between their personal relationships and therapy process. The present study examines the relationship between emotion management at home and emotion management at work to job satisfaction and marital satisfaction of marriage and family therapists. Results suggest that men and women experience a different interaction between emotion management, relationship satisfaction, and job satisfaction.
