An objective test of goodness of fit of the continuous strength model in STM

The continuous strength model of recognition memory was evaluated in a task where Ss were tested for recognition of 10-number lists using a rating procedure. Maximum likelihood estimates of the parameters of the model were obtained by an iterative method on a high-speed computer, and a chi-square goodness-of-fit test was performed for individual Ss. For 15 of 20 Ss, the chi-square values were nonsignificant, p < .05, indicating that the model provided a good fit to the data. Although the model gave a good fit to the data, the Δm measure of sensitivity was highly correlated with a true recognition score computed by subtracting false alarmsfrom correct recognitions.     

An investigation of the relationships between problem solving strategies, representation and memory

There has been considerable debate in recent years about the status of “imagery” in problem solving. The present experiment attempts to show that while subjects may employ representational strategies when they first encounter a class of problems, they abandon such strategies as they gain experience with the problems. It does this by asking subjects to answer unexpected questions which are based upon the information which they have just used to solve a problem. The hypothesis, which is supported by the results, is that increasing experience with problems will be paralleled by a decreasing ability to answer unexpected questions. The experiment also shows that such effects are not attributable to a build-up in proactive interference.     

The impact of event vividness,event severity,and prior paranormal belief on attributions towards a depicted remarkable coincidence experience: Two studies examining the misattribution hypothesis

Two studies examine the impact event vividness, event severity, and prior paranormal belief has on causal attributions for a depicted remarkable coincidence experience. In Study 1, respondents (n = 179) read a hypothetical vignette in which a fictional character accurately predicts a plane crash 1 day before it occurs. The crash was described in either vivid or pallid terms with the final outcome being either severe (fatal) or non‐severe (non‐fatal). Respondents completed 29 causal attribution items, one attribution confidence item, nine scenario perception items, a popular paranormal belief scale, and a standard demographics questionnaire. Principal axis factoring reduced the 29 attribution items to four attribution factors which were then subjected to a 2 (event vividness) × 2 (event severity) × 2 (paranormal belief) MANCOVA controlling for respondent gender. As expected, paranormal believers attributed the accurate crash prediction less to coincidence and more to both paranormal and transcendental knowing than did paranormal sceptics. Furthermore, paranormal (psychokinesis) believers deemed the prediction more reflective of paranormal knowing to both (1) a vivid/non‐fatal and (2) a pallid/fatal crash depiction. Vividness, severity, and paranormal belief types had no impact on attribution confidence. In Study 2, respondents (also n = 179) generated data that were a moderately good fit to the previous factor structure and replicated several differences across attributional pairings albeit for paranormal non‐believers only. Corresponding effects for event severity and paranormal belief were not replicated. Findings are discussed in terms of their support for the paranormal misattribution hypothesis and the impact of availability biases in the form of both vividness and severity effects. Methodological issues and future research ideas are also discussed.     

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.     

Social media addiction and psychological adjustment: religiosity and spirituality in the age of social media

Previous research indicates a significant association between social media use and psychological adjustment. The present study investigated whether religiosity/spirituality mediates the relationship between social media intrusion and psychological adjustment. Participants completed a demographic questionnaire, Religious Commitment Inventory-10, Spirituality Index of Well-Being, the DASS-21 Scales, and the Facebook Intrusion Questionnaire, which was altered slightly to include all types of social media. Results revealed that social media intrusion was significantly positively associated with depression, anxiety, and stress, and negatively correlated with spiritual well-being and the self-efficacy component of spiritual well-being. Furthermore, the self-efficacy dimension of spiritual well-being partially mediated the association between social media intrusion and psychological stress. From these results, it may be inferred that higher social media intrusion may have the ability to decrease specific aspects of spirituality, which may, in turn, negatively impact psychological adjustment. Limitations and future directions are discussed.     

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.
