What makes distributed practice effective?

The advantages provided to memory by the distribution of multiple practice or study opportunities are among the most powerful effects in memory research. In this paper, we critically review the class of theories that presume contextual or encoding variability as the sole basis for the advantages of distributed practice, and recommend an alternative approach based on the idea that some study events remind learners of other study events. Encoding variability theory encounters serious challenges in two important phenomena that we review here: superadditivity and nonmonotonicity. The bottleneck in such theories lies in the assumption that mnemonic benefits arise from the increasing independence, rather than interdependence, of study opportunities. The reminding model accounts for many basic results in the literature on distributed practice, readily handles data that are problematic for encoding variability theories, including superadditivity and nonmonotonicity, and provides a unified theoretical framework for understanding the effects of repetition and the effects of associative relationships on memory.     

Polynomial Regression with Response Surface Analysis: A Powerful Approach for Examining Moderation and Overcoming Limitations of Difference Scores

Polynomial regression with response surface analysis is a sophisticated statistical approach that has become increasingly popular in multisource feedback research (e.g., self-observer rating discrepancy). The approach allows researchers to examine the extent to which combinations of two predictor variables relate to an outcome variable, particularly in the case when the discrepancy (difference) between the two predictor variables is a central consideration. We believe this approach has potential for application to a wide variety of research questions. To enhance interest and use of this technique, we provide ideas for future research directions that might benefit from the application of this analytic tool. We also walk through a step-by-step example of how to conduct polynomial regression and response surface analysis and provide all the tools you will need to do the analyses and graph the results (including SPSS syntax, formulas, and a downloadable Excel spreadsheet). Our example involves how discrepancies in perceived supervisor and organizational support relate to affective commitment. Finally, we discuss how this approach is a better, more informative alternative to difference scores and can be applied to the examination of two-way interactions in moderated regression.     

Honesty–humility and a person–situation interaction at work

Person–situation interactions have attracted researchers' attention for decades. Likewise, the current work focuses on the interaction of honesty–humility and situational conditions in bringing about counterproductive work behaviour (CWB). As such, we introduce perceptions of organizational politics as a situational construct representing an opportunity for CWB. In a sample of N = 148 employees we found that particularly individuals low in honesty–humility were affected by situational circumstances. By contrast, those high in honesty–humility reported practically the same (lower) amount of CWB independent of the level of perceptions of organizational politics. In other words, employees low in honesty–humility were especially likely to condition their behaviour on environmental factors, a result that mirrors previous findings.

Investigating the Moderating Role of Cultural Practices on the Effect of Selection Fairness Perceptions

Utilizing a sample of applicants to positions in a global corporation, we examined whether cultural practices moderate the effect of selection fairness perceptions on organizational attractiveness and job choice. Positive relationships were anticipated between fairness perceptions and outcomes, and performance orientation and uncertainty avoidance cultural practices were hypothesized to moderate the effects of structural and information sharing perceptions, respectively. Structural fairness perceptions were positively associated with both outcomes, but information‐sharing perceptions were significantly related only to organizational attractiveness. National variability in the effect of selection fairness perceptions was observed only for the effect of structural perceptions on organizational attractiveness. Performance orientation moderated this effect such that the strongest relationship was seen among applicants from more performance‐oriented countries.     

Primary Care Providers’ Responses to Patient-Generated Family History

Family health history is one of the best predictors of an individual’s risk for common disease, yet it is underutilized in routine care. Although the Surgeon General has recommended consumers record their family health history and share it with their health care provider, providers’ perceptions of patient-generated family histories are unknown. To learn more about providers’ experience with and perceptions about patient-generated family histories, we mailed surveys to 301 providers and had a response rate of 24% (n = 68). Seventy-three percent felt a patient-generated computer pedigree would improve their ability to assess risk as compared to their current methods. Seventy percent felt a patient-generated computer pedigree would either have no effect on or would increase the number of patients that could be seen in a day. Results suggest that providers appreciate the potential benefits of patient-generated family histories. Genetic counselors and nurses are in a prime position to promote and facilitate the use of patient-generated family health histories in routine care.     

Metaphor priming in sentence production: Concrete pictures affect abstract language production

People speak metaphorically about abstract concepts—for instance, a person can be “full of love” or “have a lot of love to give.” Over the past decade, research has begun to focus on how metaphors are processed during language comprehension. Much of this work suggests that understanding a metaphorical expression involves activating brain and body systems involved in perception and motor control. However, no research to date has asked whether the same is true while speakers produce language. We address this gap using a sentence production task. Its results demonstrate that visually activating a concrete source domain can trigger the use of metaphorical language drawn from that same concrete domain, even in sentences that are thematically unrelated to the primes, a metaphorical priming effect. This effect suggests that conceptual metaphors play a part in language production. It also shows that activation in the perceptual system that is not part of an intended message can nevertheless influence sentence formulation.     

The ‘too muchness’ of excitement: Sexuality in light of excess,attachment and affect regulation

This paper brings together contemporary thinking about early attachment and affect regulation with our clinical and theoretical understanding of the problems of adult sexuality. In addition to recent theories of affect regulation and attachment, we incorporate Laplanche's idea of ‘excess’, which was an important transitional concept integrating real experience with fantasy in sexuality. We elaborate the idea of excess –‐ ‘too‐muchness’ –‐ to illuminate the early overwhelming of the psyche that affects the formation of sexuality. Linked to recent theoretical developments, this idea helps to grasp the relationship between sexual excitement and early affect regulation, showing how excitement becomes dangerous, thus impeding or distorting desire. The ‘too‐muchness’ of excitement recalls the experience of being a stimulated, overwhelmed, unsoothed child and influences later inability to tolerate sexual arousal and the excitement affect. A clinical case illustrates this connection between attachment trauma, anxiety about sexuality, as well as shameful experiences of gender identity as an area of trauma. We emphasize the importance of working through the terrors and desires of the mother–baby relationship as they emerge in the transference–countertransference in order to develop the ability to hold excitement and stimulation without experiencing the too‐much as the intolerable. This includes the working‐through of ruptures related to overstimulation as well as the delicate balance of attention to fantasy and intersubjective work in the transference.
