ABSTRACT Dependency plays an important role in both normal and abnormal personality, but the construct remains loosely defined, both in clinical practice and the research literature. Moreover, although a number of measures purport to measure trait dependency, little agreement exists as to the structure of dependency within or across these instruments. Furthermore, what constitutes the low end of trait dependency remains unclear. Five hundred nine undergraduates completed a battery of 14 dependency scales and subscales, a subset of whom (n=322) also completed a broad measure of personality pathology (SNAP‐2). Exploratory factor analysis of the dependency measures yielded two correlated factors—Passive‐Submissive and Active‐Emotional dependency—as well as a third, unrelated factor, Detachment/Autonomy, all with differential correlates to the pathological personality traits of the SNAP‐2. Taken together, these data suggest a clear, 2‐factor model for trait dependency that is distinct from detachment/autonomy.  相似文献

We have previously shown that repeated retrievals of remote autobiographical memories over the course of one month led to an overall increase in reported detail (Nadel, Campbell, & Ryan, 2007). The current study examined the retrieval of those same memories 1 year later in order to determine whether the level of detail remained stable or whether the memories returned to their original state. Participants reported even more details than they had recalled at least 1 year earlier, including new details that were reported for the first time. This finding was consistent across both multiple and single retrieval conditions, suggesting that the critical factor leading to the increase in recall was the passage of time. These findings provide evidence for long-term effects of repeated retrieval on memory content.  相似文献

This study examined the relationships between proactive personality and employee creativity and the moderating roles of job creativity requirement and supervisor support for creativity in activating proactive personality associated with employee creativity. To provide a rigorous test of the hypotheses, we conducted a field study from a sample of 157 employee–supervisor pairs in South Korea. The results revealed that a proactive personality was positively associated with employee creativity. In addition, job creativity requirement and supervisor support for creativity jointly influenced the relationship between proactive personality and employee creativity. Specifically, proactive employees exhibited the highest employee creativity when job creativity requirement and supervisor support for creativity were both high.  相似文献

To evaluate the efficacy of cognitive rehabilitation therapies (CRTs) for mild cognitive impairment (MCI). Our review revealed a need for evidence-based treatments for MCI and a lack of a theoretical rehabilitation model to guide the development and evaluation of these interventions. We have thus proposed a theoretical rehabilitation model of MCI that yields key intervention targets–cognitive compromise, functional compromise, neuropsychiatric symptoms, and modifiable risk and protective factors known to be associated with MCI and dementia. Our model additionally defines specific cognitive rehabilitation approaches that may directly or indirectly target key outcomes–restorative cognitive training, compensatory cognitive training, lifestyle interventions, and psychotherapeutic techniques. Fourteen randomized controlled trials met inclusion criteria and were reviewed. Studies markedly varied in terms of intervention approaches and selected outcome measures and were frequently hampered by design limitations. The bulk of the evidence suggested that CRTs can change targeted behaviors in individuals with MCI and that CRTs are associated with improvements in objective cognitive performance, but the pattern of effects on specific cognitive domains was inconsistent across studies. Other important outcomes (i.e., daily functioning, quality of life, neuropsychiatric symptom severity) were infrequently assessed across studies. Few studies evaluated long-term outcomes or the impact of CRTs on conversion rates from MCI to dementia or normal cognition. Overall, results from trials are promising but inconclusive. Additional well-designed and adequately powered trials are warranted and required before CRTs for MCI can be considered evidence-based.  相似文献

Studies of sensory guidance of movement in animals show that large nervous systems are not necessary for accurate control, suggesting that guidance may be based on some simple principles. In search for those principles, a theory of guidance of movement is described, which has its roots in Gibson's pathfinding work on visual control of locomotion (J. J. Gibson, 1958/this issue). The theory is based on the use of the simple but powerful variable tau, the time-to-closure of a gap at the current gap closure rate (whatever the gap's dimension—distance, angle, force, etc.); and on the principle of tau-coupling (keeping two Ts in constant ratio). In this article, I show how tau-coupling could be used to synchronize movements and regulate their kinematics. Supportive experimental results are reported. I also show theoretically how sensory-taus, defined on sensory input arrays, can specify motion-taus through tau-coupling; how the braking procedure of keeping tau.dot stable is a particular case of tau.coupling; and how tools for steering (e.g., limbs, whole bodies, cars, or aircraft) could be built from tau-couplings, which would enable steering control in a variety of situations, including steering straight and curved courses to goals, steering and controlling speed at the same time, steering around obstacles, and asymptoting on surfaces as when landing. Some movements also involve intrinsic guidance from within, and a hypothesis on intrinsic guidance by tau is introduced, supported by experiments spanning different activities.  相似文献

Abstract

The present paper provides a conceptual basis for the examination of mood in sport. The nature of the mood construct is discussed with reference to related constructs. A conceptual model is presented which proposes that certain mood dimensions interact to influence behavior. Depression is proposed to be the most important mood dimension, influencing the intensity of mood responses, the interrelationships among other mood dimensions, and moderating mood and performance relationships for anger and tension. It is hoped that the conceptual model will help guide applied interventions and will act as a catalyst for future research.  相似文献

This study tested the dual‐process motivational (DPM) model, which posits that right‐wing authoritarianism (RWA) and social dominance orientation (SDO) differentially predict attitudes toward socially threatening or subordinate groups, respectively. Participants read articles on same‐sex relationships and affirmative action and evaluated the article content and the biases of the article authors. The article conclusions (i.e., pro‐ or anti‐same‐sex relationships and affirmative action) were varied between subjects. As expected, only RWA predicted evaluations of the same‐sex relationships articles and authors, whereas only SDO predicted evaluations of the affirmative action articles and authors. These results extend applications of the dual‐process model by demonstrating that RWA and SDO differentially predict evaluations of political information that pertains to socially threatening or subordinate groups, respectively.  相似文献

This study investigates the longitudinal relationships between burnout and depression among teachers. Middle and high school teachers participated in a 3‐wave survey. The results of the latent growth modeling analysis revealed that there was a significant relationship between the initial status of burnout and the initial status of depression. Results also indicated a significant relationship between the change rate of burnout and the change rate of depression. Moreover, the autoregressive cross‐lagged modeling revealed a causal relationship such that teacher's burnout leads to subsequent depression symptoms, not vice versa.  相似文献

This study examined the Chinese name-pronunciation effect. The easy-to-pronounce and difficult-to-pronounce Chinese names were created using the same characters in order to control for visual perceptual and conceptual fluency. In Experiment 1, participants rated each name in terms of liking, electability as a state leader, income level, and baby name preference. An additional rating of prevalence was used to estimate familiarity. In Experiment 2, participants did not read the name aloud before rating and performed intentional recall and recognition tests. In both experiments, the easy-to-pronounce names were rated higher than difficult-to-pronounce names on liking. This effect generalized to judgments of electability and baby name preference but not to prevalence and income level. There were no differences in memory performances between the two types of names. Results are discussed in terms of the boundary condition of the name-pronunciation effect and the advantage of using Chinese names to study this effect.  相似文献
