Auditory delayed matching in the bottlenose dolphin

A bottlenose dolphin, already highly proficient in two-choice auditory discriminations, was trained over a nine-day period on auditory delayed matching-to-sample and then tested on 346 unique matching problems, as a function of the delay between the sample and test sounds. Each problem used new sounds and was from five to 10 trials long, with the same sound used as the sample for all trials of a problem. At each trial, the sample was projected underwater for 2.5 sec, followed by a delay and then by a sequence of two 2.5-sec duration test sounds. One of the test sounds matched the sample and was randomly first or second in the sequence, and randomly appeared at either a left or right speaker. Responses to the locus of the matching test sound were reinforced. Over nine, varying-sized blocks of problems, the longest delay of a set of delays in a block was progressively increased from 15 sec initially to a final value of 120 sec. There was a progressive increase across the early blocks in the percentage of correct Trial 1 responses. A ceiling-level of 100% correct responses was then attained over the final six blocks, during which there were 169 successive Trial 1 responses bracketed by two Trial 1 errors (at 24- and 120-sec delays). Performance on trials beyond the first followed a similar trend. Finally, when the sample duration was decreased to 0.2 sec or less, matching performance on Trial 1 of new problems dropped to chance levels.     

Passion for a Cause: How It Affects Health and Subjective Well‐Being

Using the dualistic model of passion (Vallerand et al., 2003), this research investigated how harmonious passion (HP) or obsessive passion (OP) for a cause can affect volunteers' health and subjective well‐being. Three studies with volunteers for local (local emergency crises and community help) and international (humanitarian missions) causes assessed physical and psychological health using cross‐sectional and longitudinal designs. Study 1 (N = 108) showed that HP was positively related to satisfaction with one's involvement in the cause and unrelated to physical injuries due to cause involvement. OP was unrelated to satisfaction but positively associated with injuries. Findings were replicated in Study 2 (N = 83). Moreover, self‐neglect mediated the positive and negative effects of HP and OP, respectively, on injuries. Study 3 (N = 77) revealed that HP predicted an increase in satisfaction and health over a 3‐month mission. OP predicted an increase in physical symptoms and a decrease in health. Furthermore, OP before a mission was positively related to self‐neglect that was positively associated with physical symptoms after a mission. OP also positively predicted rumination that was conducive to posttraumatic stress disorder. HP was unrelated to these variables. Findings underscore the role of passion for a cause in predicting intrapersonal outcomes of volunteers.     

Domain Satisfaction as a Mediator of the Relationship Between Work–Family Spillover and Subjective Well-Being: A Longitudinal Study

Purpose

Despite greater recognition that public and workplace policies are needed to facilitate work–family integration, scarce evidence exists on whether and how work–family spillover relates to future subjective well-being (SWB). Guided by conservation of resources theory and bottom-up theories of SWB (i.e., domain-specific satisfaction serves as a source of overall SWB), we investigated the relationship between work–family spillover and future life satisfaction and the potential mechanisms of the relationship (job and marital satisfaction). The relative contribution of positive and negative work–family spillover to SWB was also examined.

Design/Methodology/Approach

Lagged analyses were conducted on self-reported data from a representative U.S. sample over a 9-year interval (N = 2588).

Findings

Individuals who experienced negative work-to-family spillover were less satisfied with their life at a 9-year follow-up, whereas those who experienced positive family-to-work spillover reported higher life satisfaction at the follow-up. These prospective associations remained significant when considering other established predictors of life satisfaction (baseline life satisfaction, health, gender, income, and personality) and were mediated by job satisfaction and marital satisfaction.

Implications

This study provides empirical evidence for ongoing advocacy for working families, suggesting that policies that facilitate positive family-to-work spillover and minimize negative work-to-family spillover should be regarded as essential to enhance SWB of individuals in our society in the long run.

Originality/Value

This study expands our understanding of the causal relationship between work–family spillover and life satisfaction by considering both positive and negative spillover and demonstrating the mechanisms by which work–family spillover relates to future life satisfaction, even beyond personality, health, and income.

     

Using Tablets to Collect Data From Young Children

Mobile, touch-screen devices are increasingly ubiquitous in children’s lives. The extensive use of such devices presents an exciting opportunity for data collection. We describe a simple method for creating cross-platform, interactive tablet experiments using open Web-based resources. We illustrate this method by collecting data from 1- to 4-year-old children in a word-recognition paradigm, using 3 different techniques: tablets, eye tracking, and an in-person storybook paradigm. Both accuracy and reaction-time data from the tablet compared favorably with the other methods. Tablets should be considered as a viable method for collecting low-cost, well-controlled developmental data.     

A Common Factors Approach to Psychotherapy Training

This article addresses training in psychotherapy integration from the perspective of common factors. Problems related to this training perspective are first reviewed. As an attempt to deal with such problems, current teaching and supervision efforts by the author are briefly described. Based on a developmental model of clinical learning, a sketch of a more comprehensive program of integrative psychotherapy training is advanced.     

A study of the test of supervisory skills

In supervisory selection and development it is important to assess individuals' supervisory competencies. In a field study, the Test of Supervisory Skills was validated against a surrogate criterion of supervisory performance, based upon position classification and supervisory experience. Subjects (N=2406), workers and applicants of both sexes, were recruited from multiple sources, tested, and the data analyzed to evaluate the usefulness of the test in human resource management applications. Both the current and prior results show significant relationships between scores on this test and various criteria of supervisory performance.
