Breaking Down Barriers: Museum as Broker of Home/School Collaboration

ABSTRACT

Parents have a major influence on children's learning, yet parent involvement remains weak in many communities. This article addresses the role of a museum in bringing home and school together, describing results from 2 complementary studies of a museum-designed and -implemented parent involvement program. The first study was an exploratory, mixed-methods investigation designed to understand the program's impact on parents' engagement in their children's learning. The second study used a grounded theory approach to develop theoretical hypotheses about the programmatic mechanisms that facilitated parents' engagement. In terms of impact, the program gave parents a platform through which to create new and more meaningful spaces for connecting to their children's learning, including conceptual spaces, social spaces, and physical spaces. In terms of mechanisms, the program first helped parents to build relevant capital and then to author new and relevant ways of engaging with their children's schooling. Taken together, study results broaden current thinking about the spaces in which parent engagement occurs and emphasize the important community-based role that museums can play to bring parents and schools together in support of children's development.     

SPaM: A combined self-paced reading and masked-priming paradigm

In this article, we validate an experimental paradigm, SPaM, that we first described elsewhere (Luke & Christianson, Memory & Cognition 40:628–641, 2012). SPaM is a synthesis of self-paced reading and masked priming. The primary purpose of SPaM is to permit the study of sentence context effects on early word recognition. In the experiment reported here, we show that SPaM successfully reproduces results from both the self-paced reading and masked-priming literatures. We also outline the advantages and potential uses of this paradigm. For users of E-Prime, the experimental program can be downloaded from our lab website, http://epl.beckman.illinois.edu/.     

Mental well-being in the religious and the non-religious: evidence for a curvilinear relationship

Previous studies demonstrating a positive relationship between religiosity and mental health have sampled from a highly religious general population with little differentiation between weak religiosity and non-religiosity. Church members are typically compared with non-religious unaffiliated individuals, thus confounding belief with group effects (e.g. social support). The present study examined mental well-being, utilising the full range of certainty of belief or non-belief in God. In the first study, we compared church and secular group members on measures of life satisfaction and emotional stability. The second study used a large survey of the non-religious. A curvilinear relationship was found such that those with higher belief certainty (both confidently religious and atheists) have greater well-being relative to those with low certainty (unsure and agnostics). Multiple regressions controlling for social and demographic variables reduced, but did not eliminate this curvilinear relationship. Mechanisms of well-being may involve a confident worldview rather than religious beliefs themselves.     

Moralized memory: binding values predict inflated estimates of the group’s historical influence

ABSTRACT

Collective memories are memories or historical knowledge shared by individual group members, which shape their collective identity. Ingroup inflation, which has previously also been referred to as national narcissism or state narcissism, is the finding that group members judge their own group to have been significantly more historically influential than do people from outside the group. We examined the role of moral motivations in this biased remembering. A sample of 2118 participants, on average 42 from each state of the United States, rated their home state’s contribution to U.S. history, as well as that of ten other states randomly selected. We demonstrated an ingroup inflation effect in estimates of the group’s historical influence. Participants’ endorsement of binding values – loyalty, authority, and sanctity, but particularly loyalty – positively predicted the size of this effect. Endorsement of individuating values – care and fairness – did not predict collective narcissism. Moral motives may shape biases in collective remembering.     

What if they knocked down the library and nobody noticed? The failure to detect large changes to familiar scenes

The purpose of the current study was to investigate people's ability to detect changes to familiar scenes. College students were asked either to identify what was wrong with a picture of a familiar location on their college campus (e.g., the library had been removed from the scene), or to estimate the difficulty of change detection for a hypothetical cohort performing the same task. Performance in the change-detection condition was extremely poor, even when changes were large. Participants who were familiar with the scenes and those who were unfamiliar with the scenes both overestimated the actual levels of change-detection performance. A follow-up analysis indicated that the participants who were unfamiliar with the scenes produced estimations of difficulty that were highly correlated with the mathematical area of the change, whereas participants who were familiar with the scenes produced estimations of difficulty that were highly correlated with the actual difficulty of change detection. The results indicate that people's visual long-term memory for familiar scenes lacks the precision to be able to effectively identify even large-scale changes, although subjectively people believe this should be relatively easy.     

Trait Extraversion and Dopamine Function

An influential theory within personality neuroscience suggests that trait extraversion is underpinned by individual differences in dopamine function. In a review of the relevant literature, we evaluate this theory in light of the evidence from molecular genetics, neuroimaging, and psychopharmacology. Evidence linking individual differences in extraversion with dopamine‐relevant genes, structural volume of dopamine‐rich brain regions (e.g., in striatal and ventral prefrontal areas), dopamine receptor availability, and frontal alpha asymmetry is mixed at best. Evidence concerning both scalp recorded (electroencephalogram) and hemodynamic (functional magnetic resonance imaging) neural responses to rewards appears somewhat more promising. Perhaps the best evidence concerns extraversion‐dependent responses – both neural and behavioural – to dopaminergic drugs. Future research in this area must go beyond the demonstration of theoretically consistent associations and attempt to provide more specific causal evidence for the dopamine hypothesis of extraversion. A further challenge is to expand this hypothesis to incorporate other neurobiological processes that are likely to underlie this trait.
