Few studies have investigated simple discrimination and discrimination reversal learning by children younger than 2 years. Extant research has shown that teaching discrimination reversals may be challenging with this population. We used social reinforcement and correction procedures to teach simple simultaneous discrimination and discrimination reversal tasks involving three pairs of animal pictures displayed in a paper notebook. Participants were eight typically developing toddlers aged 15-23 months. All learned at least one simple discrimination/discrimination reversal problem. Four children learned all problems and showed evidence of learning set formation. Perhaps surprisingly, discrimination reversals were sometimes learned more rapidly than original discriminations. The procedures suggest a potentially efficient methodology for investigating more complex aspects of relational learning in toddlers.

End-stage liver disease (ESLD) is a chronic and debilitating condition associated with substantial psychological stress, morbidity, and mortality. The Connor–Davidson Resilience Scale (CD–RISC; Connor & Davidson, 2003 Connor, K. M., & Davidson, J. R. (2003). Development of a new resilience scale: The Connor– Davidson Resilience Scale (CD–RISC). Depression and Anxiety, 18(2), 7682. doi:10.1002/da.10113[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) is a commonly used resilience measure. This research examined the validity of the CD–RISC among ESLD patients (N = 120) using exploratory factor analysis. Results supported a single-factor solution after removing poorly loading items. The CD–RISC also was correlated with measures of depression, anxiety, quality of life, social support, age, and cognitive ability, thus providing evidence to support its construct validity. Future research should confirm this factor structure and examine its predictive validity prior to widespread use among ESLD patients. This research represents the first step in this process and proposes an alternative version of the CD–RISC for this population.  相似文献

A paucity of research exists examining the role of spirituality/religion (S/R) as a protective factor for combat‐deployed military personnel. The purpose of this study is to (a) define the underlying structure of items from an author‐developed instrument measuring coping, beliefs, and support; and (b) examine how S/R affiliation, activities, and practices affect coping responses for 279 combat‐deployed military personnel. Significant predictors of coping included support, age, Christian affiliation, and frequency of S/R practices. The authors found that beliefs, S/R practices prior to deployment, previous combat deployments, and first deployment were not significant predictors of coping. Implications for counselors and future research are addressed.  相似文献

Intuition suggests that the Martin Luther King holiday (MLK Day) should improve racial attitudes toward African Americans. However, its influence may depend on whether African Americans are evaluated as a group or individually. In two studies, we assessed racial attitudes either on MLK Day or on a control day. As might be expected, participants had more sympathetic attitudes towards African Americans as a group on MLK Day compared to control days; however, they evaluated individual African American exemplars more negatively on MLK Day compared to control days, who presumably seemed worse by comparison to the eminent political figure.  相似文献
