This article describes an approach for assessing and comparing complex cognition in rhesus monkeys and pigeons by training them in a sequence of synergistic tasks, each yielding a whole function for enhanced comparisons. These species were trained in similar same/different tasks with expanding training sets (8, 16, 32, 64, 128 … 1024 pictures) followed by novel‐stimulus transfer eventually resulting in full abstract‐concept learning. Concept‐learning functions revealed better rhesus transfer throughout and full concept learning at the 128 set, versus pigeons at the 256 set. They were then tested in delayed same/different tasks for proactive interference by inserting occasional tests within trial‐unique sessions where the test stimulus matched a previous sample stimulus (1, 2, 4, 8, 16 trials prior). Proactive‐interference functions revealed time‐based interference for pigeons (1, 10 s delays), but event‐based interference for rhesus (no effect of 1, 10, 20 s delays). They were then tested in list‐memory tasks by expanding the sample to four samples in trial‐unique sessions (minimizing proactive interference). The four‐item, list‐memory functions revealed strong recency memory at short delays, gradually changing to strong primacy memory at long delays over 30 s for rhesus, and 10 s for pigeons. Other species comparisons and future directions are discussed. 相似文献

Criminological examination of substance use is common in the extant literature; however, little research has examined heroin use among adolescents. Recent trends in drug use indicate a rise of heroin among adolescents indicating a need to provide theoretical explanations of this phenomenon. This study examines the efficacy of social learning theory and social bond theory to explain heroin use. The study uses a nationally representative sample of adolescents from the Monitoring the Future Survey (N = 2,465). The results support the central arguments from social structure social learning theory. First, the results show that social structure components have links with heroin use. Second, the results show that social learning theory mediates the effect of social structure measures on heroin use. The results are discussed. 相似文献

This literature review attempts to interface counselling with alternative legal practice. The authors proceed by contrasting the adversarial nature of litigation with the conciliatory nature of alternative dispute resolution (ADR) with a view to encouraging seekers of dispute resolution to opt for ADR in lieu of litigation. The paper discusses the Ubuntu world view in conflict resolution in relation to ADR practices. While not presenting ADR as a replacement for litigation nor proscribing litigation in itself, this paper prescribes the use of ADR to arrive at settlements that are more satisfactory and longer lasting. The paper finally shows how counsellors and guidance professionals may be involved in ADR processes to effectively give succour to conflicting parties. 相似文献

We developed a Spanish‐language version of the Questions About Behavioral Function (QABF) utilizing a forward‐adaptation and back‐adaptation translation process. Subsequently, we administered the assessment with 80 bilingual participants to assess the reliability and validity of the instrument. Results demonstrated that the Spanish version of the QABF was both reliable (i.e., was internally consistent) and valid (i.e., identified the correct function). Implications and future research are discussed. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

Psychological resilience, positive emotions, and successful adaptation to stress in later life 总被引:3,自引:0,他引:3

In 3 studies, the authors investigated the functional role of psychological resilience and positive emotions in the stress process. Studies 1a and 1b explored naturally occurring daily stressors. Study 2 examined data from a sample of recently bereaved widows. Across studies, multilevel random coefficient modeling analyses revealed that the occurrence of daily positive emotions serves to moderate stress reactivity and mediate stress recovery. Findings also indicated that differences in psychological resilience accounted for meaningful variation in daily emotional responses to stress. Higher levels of trait resilience predicted a weaker association between positive and negative emotions, particularly on days characterized by heightened stress. Finally, findings indicated that over time, the experience of positive emotions functions to assist high-resilient individuals in their ability to recover effectively from daily stress. Implications for research into protective factors that serve to inhibit the scope, severity, and diffusion of daily stressors in later adulthood are discussed. 相似文献
