Imagery appears to be associated with higher levels of anxiety than does worry. Borkovec has argued that worry could be a way of avoiding distressing imagery and the associated affect. Thus worry could suppress emotional activation, interfere with emotional processing, and contribute to the maintenance of anxiety. This hypothesis suggests that short and long-term effects of worrying after experiencing a distressing stimulus should differ from the effects of engaging in imagery. In the short term, imagery should maintain anxiety while worry should not do so, or should do so less. In the longer term, worry should be a less successful way of reducing anxiety associated with the stimulus than imagery, and should be followed by a greater number of intrusive cognitions (indicating the relative failure of emotional processing). These predictions were tested by asking subjects to worry, engage in imagery or “settle down” after watching a distressing video. The results were broadly consistent with the hypothesis. Other interpretations are also considered.

Purpose The purpose of this paper is to investigate the additive and differential effects of short-term-oriented group incentives (STOGIs) and long-term-oriented group incentives (LTOGIs) on psychological ownership and organizational commitment. Design/methodology/approach This study analyzed data from 17,255 US employees in the 2005 data set of the National Bureau of Economic Research Shared Capitalism Research. Findings Both additive indices of group incentives have direct positive relationships with psychological ownership and organizational commitment, as well as indirect positive relationships with organizational commitment through psychological ownership. STOGIs have a stronger relationship with organizational commitment and LTOGIs have a stronger relationship with psychological ownership. Originality/value The value of this research lies in exploring the differential effects of short-and long-term group incentives, which provides new insight into the theory of group incentives and practical implications for their effective utilization.

Abstract Study Objectives To evaluate the contribution of long-term and short-term REM sleep homeostatic processes to REM sleep recovery and the ultradian organization of the sleep wake cycle. Methods Fifteen rats were sleep recorded under a 12:12 LD cycle. Animals were subjected during the rest phase to two protocols (2T2I or 2R2I) performed separately in non-consecutive experimental days. 2T2I consisted of 2 h of total sleep deprivation (TSD) followed immediately by 2 h of intermittent REM sleep deprivation (IRD). 2R2I consisted of 2 h of selective REM sleep deprivation (RSD) followed by 2 h of IRD. IRD was composed of four cycles of 20-min RSD intervals alternating with 10 min of sleep permission windows. Results REM sleep debt that accumulated during deprivation (9.0 and 10.8 min for RSD and TSD, respectively) was fully compensated regardless of cumulated NREM sleep or wakefulness during deprivation. Protocol 2T2I exhibited a delayed REM sleep rebound with respect to 2R2I due to a reduction of REM sleep transitions related to enhanced NREM sleep delta-EEG activity, without affecting REM sleep consolidation. Within IRD permission windows there was a transient and duration-dependent diminution of REM sleep transitions. Conclusions REM sleep recovery in the rat seems to depend on a long-term hourglass process activated by REM sleep absence. Both REM sleep transition probability and REM sleep episode consolidation depend on the long-term REM sleep hourglass. REM sleep activates a short-term REM sleep refractory period that modulates the ultradian organization of sleep states.

Purpose A conceptual framework is proposed to better understand the experience of people who have dyspnea (breathing discomfort) when speaking: its nature, its physiological mechanisms, and its impacts on their lives. Method The components of the framework are presented in their natural order. They are a Speaking Domain (Speaking Activities and Speaking Variables), a Physiological Domain (Speech Breathing Variables and Physiological Mechanisms), a Perceptual Domain (Dyspnea), a Symptom Impact Domain (Emotional Responses, Immediate Behavioral Responses, and Long-Term Behavioral Response), and a Life Impact Domain (Short-Term Impacts and Long-Term Impacts). Results We discuss literature that most directly supports these components and includes findings from healthy people and those with disorders in whom speaking dyspnea was either evoked or measured. Caveats are noted where information is limited and further study is needed. A case example is provided to illustrate how to apply the framework. Conclusions This framework provides a broader view of the elements that contribute to the experience of speaking dyspnea. It is meant to guide researchers, clinicians, instructors, caregivers, and those for whom speaking dyspnea is a daily or even a life-long challenge.

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.
