Enabling Interactive Exploration of Cultural Heritage: An Experience of Designing Systems for Mobile Devices

Interaction design of mobile systems is a complex activity because it requires considering new usability and user experience aspects in order to exploit the peculiar characteristics of mobile devices, such as their pervasive and ubiquitous nature. This paper discusses issues about designing, developing and evaluating mobile systems. Italy has a rich cultural heritage, and the focus in this study is on the design of systems that enable interactive exploration of historical sites, not only for enhancing the user experience but also for learning purposes. The experience of the researchers at the Interaction, Visualisation and Usability lab, University of Bari, Italy, in designing a mobile learning system, called Explore!, which supports young students learning ancient history during a visit to archaeological parks, is reported. The evaluation of Explore! through systematic field studies shows that the adopted approach is able to transform the visit to archaeological parks into a more complete and culturally rich experience.     

Genetic architecture of verbal abilities in children and adolescents

The etiology of individual differences in general verbal ability, verbal learning and letter and category fluency were examined in two independent samples of 9‐ and 18‐year‐old twin pairs and their siblings. In both age groups, we observed strong familial resemblance for general verbal ability and moderate familial resemblance for verbal learning, letter and category fluency. All familial resemblance was explained by genetic factors. There was significant covariance among the tests, which was stronger in magnitude in the adolescent cohort. The covariance was mainly explained by genetic effects shared by subtests, both in middle childhood and in late adolescence. In addition to a shared set of genes that influenced all phenotypes, there were also genetic influences specific to the different verbal phenotypes.     

Preferred Difficulty and Subjective Probability in Different Action Phases

Drawing on Gollwitzer's deliberative–implemental mindset distinction (P. M. Gollwitzer, 1990), it was predicted that people who are deliberating on different actions or goals would be more cautious or more realistic in their expectation of success in subsequent tasks than people who are going to implement a chosen action or goal. Participants were given a choice between different test-materials. They were interrupted before (deliberative) or immediately after decision-making (implemental). They then either had to choose between various levels of difficulty within one type of task (Experiment 1) or they had to predict their own future performance (Experiment 2). The results showed that deliberative participants preferred less difficult tasks and overestimated their probability of success less than implemental participants. In addition, deliberative participants referred more than implemental participants to their past performance when selecting levels of difficulty or predicting future performance; however, the two groups did not differ in actual performance. Taken together, the findings suggest that people are more realistic in a deliberative than in an implemental state of mind. The present studies extend prior research because for the first time they document mindset effects on peoples' estimates concerning their future performance in the achievement domain.     

Vocal changes in stutterers and nonstutterers during monotoned speech

For years, reports have circulated that stutterers experience marked decrements in their stuttering when they speak or read in monotone. Wingate has suggested that the ameliorative effects of various novel speaking conditions on stuttering can be attributed to modifications in vocalization induced by such conditions. The present study was conducted to see whether this explanation would extend to monotoned speech as well. Ten teenage and adult stutterers and 10 normal speakers were tested in control and monotone reading conditions. Dependent measures were the frequencies of disfluency and stuttering, fundamental frequency, fundamental frequency standard deviation, vocal SPL, vocal SPL standard deviation, and fluent reading rate. Only within-group statistical comparisons were made, because members of the two groups could not be matched pairwise along critical vocal parameters. The major findings of this study indicated that across the two conditions, both groups significantly reduced their fundamental frequency, fundamental frequency standard deviation, vocal SPL and vocal SPL standard deviation. Only the stutterers exhibited a significant decrement in disfluency and stuttering. The normals did not evince enough disfluency in the control condition for a reduction to occur during monotoning. Neither group effected a reduction in fluent reading rates. These and other findings and interpretations are discussed relative to Wingate's modified vocalization hypothesis.     

A Longitudinal Study of Religiosity,Spiritual Health Locus of Control,and Health Behaviors in a National Sample of African Americans

The present longitudinal study examined religious beliefs and behaviors, spiritual health locus of control (SHLOC), and selected health-related behaviors and outcomes in a national sample of 766 African American adults. Participants were interviewed by telephone three times over a 5-year period. Results indicated that stronger religious beliefs and religious behaviors were associated with greater changes in active SHLOC. There was some evidence of direct effects of religious beliefs and behaviors on changes in health behaviors. Religious behaviors were related to greater passive SHLOC over time across some health outcomes. Passive SHLOC was associated with some less desirable health outcomes over time.     

Influence of Peers’ Types of Trust on Trust Repair: The Role of Apologies

This study aims to answer the question how previous trust experiences contextualize trust repair efforts. The concepts of calculus-based and relational trust are utilized to show the influence of the kind of trust on trust repair tactics, specifically apologies. We focus on a neglected referent of trust, that is trust between peers, and elucidate apology and its complements that might be effective between peers. We propose that the effectiveness of apologies and its specific complements depend not only on trust breach but also on the type of trust prior to a breach. Specifically, we claim that when apology is complemented with compensation or external attributions, these tactics repair trust more effectively in calculus-based trust. But, when apology is complemented with empathy, acknowledgment of violated norms, and extensive involvement, these tactics can effectively repair trust in relational trust. The paper aims to contribute to our understanding of apologies and the effectiveness of it under different conditions.     

Internationally adopted children’s cognitive and social-emotional development during the first post-adoption year: A longitudinal study

Research is consistent in showing that international adoption is an intervention leading to great recovery for adopted children, but there is a need of research on factors associated with recovery. The present study is aimed at: (a) assessing children’s cognitive skills and social-emotional dimensions on their arrival to their new family; (b) evaluating their development after one year; (c) identifying which factors influence development, taking into account children’s gender, age, health status on arrival, years of institutionalization, and the initial psychological delay. Participants were 53 internationally adopted children (30 boys and 23 girls), aged 5.68 years old on average at placement (range 2–14). Results showed that children’s development one year after adoption was extraordinary, both in cognitive skills and in social-emotional dimensions. The children more delayed on arrival showed the larger progress over time, and their recovery was greater in cognitive skills than in social-emotional dimensions.
