On the perception of a class of bilaterally symmetric forms

Two experiments were performed to determine the manner in which people perceive a class of bilaterally symmetric forms. In the first experiment, paired, comparison dissimilarity judgments and unidimensional single stimulus ratings were collected from the Ss. The second experiment involved the collecting of semantic differential and paired comparison dissimilarity judgments from two groups of Ss. The judgments and ratings from both experiments were compared to each other and to a set of objective measures of the forms by a series of multivariate statistical techniques. It was found that three primary attributes, orientation, convexity-concavity, and curvature, accounted for the perceptual reports, but the manner in which the attributes were used differed for different response procedures and for the same response on different occasions.     

Factorial invariance and significance

It is shown that invariance requirements remove the indeterminacy in factor determination and lead to an integration of factorial studies with promise of considerable reduction in computational labor. The selection of significant primary factors is discussed, with special reference to Thurstone's simple structure criterion.     

Assessing the Helpfulness of One Parenting Assistance Helpline

This study examined the services provided by one statewide warmline established to assist parents and caregivers of children from birth through adolescence. Warmlines offer telephone-based, non-crisis support for individuals experiencing diverse issues that include parenting questions and concerns. The University of Alabama Child Development Resources collaborated with the Alabama State Department of Child Abuse and Neglect Prevention to institute the Parenting Assistance Line to provide information and support to parents and caregivers of children, age birth through adolescence. Overall, the staff of the Parenting Assistance Line responded to 9487 calls during the 6 years of data reported here. Through a secondary data analysis of calls to the Parenting Assistance Line from June 2007 to July 2013, this study describes the concerns of callers in relation to the ages of the children about whom they are calling and also evaluates the perceptions of the helpfulness of the information and support provided by the warmline. We found that frequently calls involved parent support and parental stress for parents and caregivers of children from infancy through adolescence. The findings suggest that telephone assistance lines offer a viable choice for parents and caregivers seeking affordable and accessible resources when stressed by the responsibilities of caring for children and adolescents and/or seeking information related to parenting issues. The study identified the limitations of research involving secondary data collected for purposes other than research that program administrators and evaluators should consider when planning and implementing services of this nature.     

A Multi-Study Examination of Well-Being Theory in College and Community Samples

Well-being theory (WBT) proposes five indicators of well-being [i.e., positive emotion, engagement, relationships, meaning, achievement (PERMA)] that are, independently, empirically supported predictors of flourishing (i.e., an optimal level of well-being; Seligman in Flourish: a visionary new understanding of happiness and well-being. Free Press, NY, 2011). However, there is limited empirical support for the multidimensional model suggested by WBT. Two studies sought to test and validate the higher-order factor structure of the five components of PERMA and PERMA’s ability to predict concurrent and prospective flourishing outcomes (e.g., physical health, college success). In Study 1, a longitudinal examination of college students, participants completed measures of well-being (including four of the five PERMA indicators), physical health, and college success at the end of their sophomore, junior, and senior years. In Study 2, a larger, cross-sectional study was conducted online to further validate the PERMA model with a broader sample and all five PERMA indicators. Participants completed measures similar to those administered at Study 1 and other measures used to validate Study 1 measures. Results from Study 2 further validated the PERMA model by comparing Study 1 measures to established measures and by adding meaning to the model. Study 1 and Study 2 PERMA models predicted markers of well-being (e.g., vitality, life satisfaction) and flourishing (e.g., physical health). The two studies reported here provide cross-sectional and longitudinal support that WBT is useful for predicting flourishing.     

Negotiating Cultures and Identities: Education and Adaptation Among Young North Korean Settlers in South Korea

This paper examines the formation of diverse identities and the emergence of dynamic changes in cultural forms in the power structures of both newcomers and hosts in the case of North Koreans settling in South Korea. Since the end of the Korean War in 1953, the formerly homogeneous nation of Korea has been politically divided under two separate regimes: a communist society in the North and a capitalist democracy in the South. In the end of 1990s, the number of North Koreans immigrating to South Korea began to rapidly increase due to severe famine in the North; by 2014, the number of North Korean settlers in South Korea had reached more than 27,000. This qualitative study explores the resulting cultural gaps and issues of conflict, power, and resistance and emphasizes the strategies that young North Korean settlers employ as they shape and position themselves in capitalist society.     

Mind the Gaps: Are Conclusions About Mindfulness Entirely Conclusive?

Mindfulness has emerged as an important construct in the mental health field. Although evidence suggests benefits, it also appears that excitement over the clinical applications of mindfulness has largely suspended concentrated efforts to clarify fundamental elements of the construct. This article explores conceptual confusion and contrasts primary mindfulness‐based techniques before investigating attrition factors, adverse effects of mindfulness practices, and populations contraindicated for mindfulness‐based techniques. Implications for practice are provided.     

The Influence of Perpetrator Exposure Time and Weapon Presence/Timing on Eyewitness Confidence and Accuracy

Crimes can occur in a matter of seconds, with little time available for an eyewitness to encode a perpetrator's face. The presence of a weapon can further exacerbate this situation. Few studies have featured mock crimes of short duration, especially with a weapon manipulation. We conducted an experiment to investigate the impact of weapon presence and short perpetrator exposure times (3 vs. 10 seconds) on eyewitness confidence and accuracy. We found that recall concerning the perpetrator was worse when a weapon was present, replicating the weapon focus effect. However, there was no effect on eyewitness identification accuracy. Calibration analyses revealed that all conditions produced a strong confidence–accuracy relationship. Confidence–accuracy characteristic curves illustrated almost perfect accuracy for suspect identifications at the highest levels of confidence. We conclude that weapon presence during a brief crime does not necessarily result in negative consequences for either eyewitness identification accuracy or the confidence–accuracy relationship.
