Testing the limits of testing effects using completion tests

Recent work on testing effects has shown that retrieval practice can facilitate memory even for complex prose materials (Roediger & Karpicke, 2006a, 2006b). In three experiments the current study explores the effectiveness of retrieval practice on fill-in-the-blank (FITB) tests requiring the recall of specific words or phrases from a text. Final tests included both repeated items that were directly taken from initial tests, and related items. In Experiment 1, with a 2-day delay between initial and final tests, FITB testing benefited performance only on repeated items. In Experiment 2 a 7-day delay between testing sessions led to more robust effects on repeated items. However, once again no benefits were seen for related items. In Experiment 3 the scope of retrieval was varied by comparing FITB tests to paragraph recall tests requiring retrieval of all sentences following a topic sentence. Only the more open-ended recall practice demonstrated improvements in transfer to novel questions. The results suggest that scope or type of processing required during retrieval practice is likely a critical factor in whether testing will have specific or robust benefits.     

Searching for the sequential line-up advantage: A distinctiveness explanation

Signal Detection models as well as the Two-High-Threshold model (2HTM) have been used successfully as measurement models in recognition tasks to disentangle memory performance and response biases. A popular method in recognition memory is to elicit confidence judgements about the presumed old/new status of an item, allowing for the easy construction of ROCs. Since the 2HTM assumes fewer latent memory states than response options are available in confidence ratings, the 2HTM has to be extended by a mapping function which models individual rating scale usage. Unpublished data from 2 experiments in Bröder and Schütz (2009) validate the core memory parameters of the model, and 3 new experiments show that the response mapping parameters are selectively affected by manipulations intended to affect rating scale use, and this is independent of overall old/new bias. Comparisons with SDT show that both models behave similarly, a case that highlights the notion that both modelling approaches can be valuable (and complementary) elements in a researcher's toolbox.     

Testing the Impact of a Computer Guide on Visitor Learning Behaviors at an Interactive Exhibit

ABSTRACT

There is a recognized need to rigorously examine the efficacy of approaches to supporting informal learning. In this study, we used a 2 × 2 factorial experimental design to test the impact of a computer guide on 3 proximal measures of visitor learning at an interactive math exhibit. In total, 128 families were systematically assigned to engage with the exhibit either with or without access to a supplementary computer kiosk. Visitor groups with access to the computer spent longer, on average, at the exhibit and engaged in more mathematical behaviors compared to other groups. However, based on interviews, visitors with access to the computer were less likely to fully articulate the mathematical relations in the exhibit. These results suggest that although computer guides are a promising approach to supporting visitor engagement, they may, unless carefully designed, undermine other learning outcomes.     

Staff-Mediated Learning in Museums: A Social Interaction Perspective

ABSTRACT

Educators, docents, and interpreters are considered integral to the learning experiences at many museums. Although there is growing recognition that these staff members need professional development to effectively support visitor learning, there has been little research to describe their work or identify effective facilitation strategies. To address this need, we explored the nature of unstructured staff-facilitated family learning at the Oregon Museum of Science and Industry in Portland, OR, videotaping and inductively analyzing 65 unstructured staff-family interactions. The analysis highlighted the importance of role negotiation between staff and adult family members, particularly during the initiation of interactions, staff and visitor facilitation of family learning, and the introduction of new learning goals by staff members. Aligned with prior research on family learning in museums, adult family members played a critical role in shaping the nature of the interactions and determining the level of involvement of staff members. Findings have important implications for both future research and the professional development of staff.     

Objective and Interpretive Approaches to Equality in Marriage

This article differentiates two ways of studying equality in marriage: as an objective entity or as a socially constructed interpretation. Objective and interpretive researchers adopt divergent stances toward defining, measuring, and explaining marital equalities and inequalities. However, they also employ similar terms and methods, as well as exhibit mutual concern over the moral implications of research. Consequently, scholars may study marital equality in somewhat similar ways but produce reports that vary along an objective–interpretive continuum.     

A Controlled Comparison of Eye Movement Desensitization & Reprocessing and Progressive Counting

Ten therapists who were already trained and experienced in eye movement desensitization and reprocessing (EMDR) received training in progressive counting (PC), a newer trauma resolution method. Nineteen volunteers with single-incident trauma or loss were assigned to a therapist and then randomized to treatment condition; 15 completed treatment to termination criteria or until the 4th session. Participants in both conditions experienced significant reductions in post-traumatic stress disorder (PTSD) symptoms, memory-related distress, and presenting problems at one week posttreatment, and maintained at 12-week follow-up, with no significant differences in outcomes, treatment efficiency, or dropout rate. The preliminary findings of this pilot study suggest that PC is an efficient, well-tolerated, and effective trauma treatment that is relatively easy for therapists to master.     

Trespass, Animals and Democratic Engagement

Since at least the 1970s, one of the stock standard tools in the animal protection movement’s arsenal has been illegal entry into factory farms and animal research facilities. This activity has been followed by the publication of images and footage captured inside those otherwise socially invisible places. This activity presents a conundrum: trespass is illegal and it is an apparent violation of private property rights. In this paper we argue that trespass onto private property can be justified as an act of civil disobedience. We look at one particular type of justification: the use of information gathered through trespass in public policy formation. We then animate this analysis both with an historical overview of the effects of sharing information about animal agriculture, and with a specific case study of trespass undertaken recently.     

Distinguishing the Senses

Seeing, hearing and touching are phenomenally different, even if we are detecting the same spatial properties with each sense. This presents a prima facie problem for intentionalism, the theory that phenomenal character supervenes on representational content. The paper reviews some attempts to resolve this problem, and then looks in detail at Peter Carruthers' recent proposal that the senses can be individuated by the way in which they represent spatial properties and incorporate time. This proposal is shown to be ineffective in distinguishing auditory from either visual or tactual perception, and substantial classes of visual and tactual perceptions are found that the posited spatial and temporal features fail to individuate.     

Coaching preferences of adolescent youths and their parents

Abstract

This study compared preferred coaching styles of children and their parents using the Leadership Scale for Sport (LSS; Chelladurai & Saleh, 1980). The LSS preferred form was revised and then administered to children ranging from 10 to 18 years of age who competed in summer youth sport leagues and to one parent within each family unit (n = 239). A doubly multivariate repeated measure MANOVA revealed a significant multivariate difference for adolescent athletes and their parents on the five subscales of the LSS. Discriminant function and univariate analyses indicated that male and female children and their parents differed on autocratic and democratic behavior and children had a significantly higher score on democratic behavior and social support than did their parents. Parents, coaches, and researchers in youth sports could use the revised LSS to determine children-athletes’ preferences for coaching styles and for developing more effective programs.
