Listening in aging adults: from discourse comprehension to psychoacoustics.   总被引:4,自引:0,他引:4  
Older adults, whether or not they have clinically significant hearing loss, have more trouble than their younger counterparts understanding speech in everyday life. These age-related difficulties in speech understanding may be attributed to changes in higher-level cognitive processes such as language comprehension, memory, attention, and cognitive slowing, or to lower-level sensory and perceptual processes. A complicating factor in determining how these sources might contribute to age-related declines in speech understanding is that they are highly correlated. Experimenters have typically focused either on cognitive declines or sensory declines in artificially optimized test conditions. In contrast, our approach focuses on the complex interactions between age-related changes in cognitive and perceptual factors that affect spoken language comprehension, especially in nonideal, realistic conditions. In this article, we describe our attempts to systematically investigate sensory-cognitive interactions in controlled experimental situations. We begin by looking at experimental conditions that closely approximate everyday listening, and show that older adults do indeed experience deficits in spoken language comprehension relative to younger adults in these conditions. We then review further experiments designed to isolate more precisely the cognitive and perceptual sources of these age-related differences and how they vary with listening condition. In large part, we find that age-related changes in speech understanding are a consequence of auditory declines.  相似文献

This study was undertaken in an effort to sharpen selection procedures and improve faculty response to the learning needs of students. Eschewing a traditional anticipatory approach in determining suitability for training, the authors undertook a retrospective study to investigate the learning trajectories of candidates. A learning trajectory is defined as the particular way individuals learn, or fail to learn, as they advance through an Institute's training program. The database of this study grew out of the authors' experience with students in classrooms, in supervision, and from discussions about them in Progression, Selection, and The Evaluation of Learning committees. Realizing the reductionism of categorizing a highly complex and diverse group of individuals, the authors, nonetheless, found that candidates tended to group into five rather distinct categories. This paper discusses in detail the characteristics of these five categories and suggests ways in which this grouping may help in both selection and in planning more effective training for candidates. The authors are fully aware that this study has impressionistic qualities and warrants more rigorous research methods, but hope that it will arouse interest in other psychoanalytic centers and stimulate studies to corroborate, refine, or reject the conclusions reached by this group.  相似文献

This paper explores the impact of Nazi ideas and values from education in Napola schools of the National Socialist regime on the development of gender identity during late childhood and adolescence. Difficulties in this realm are illustrated by means of biographical material from a study performed at the Sigmund-Freud Institut in Frankfurt. In this study, interviews were conducted with former Napola students, their children, and grandchildren. A clinical example focuses on the theme of haircutting typical of Napola trainees and the impact this had on the development of a man's gender identity. The examination of two further generations showed that the haircut played an important role in their lives and caused difficulties in the development of masculinity, as well as femininity.  相似文献

ABSTRACT

In ‘Freedom of the Will and the Concept of a Person,’ Harry Frankfurt argues that a successful analysis of the concept ‘human’ must reveal something that distinguishes humans from non-humans, as well as indicate something informative about ‘those attributes [of ourselves] which are the subject of our most humane concern.’ In this paper, I present an analysis of Spinoza’s concept of ‘human’ as it is employed within his Ethics. I show that Spinoza’s concept of ‘human’ satisfies Frankfurt’s desiderata because I show that Spinoza’s concept of ‘human’ is, at core, a version of Frankfurt’s own. I argue that Spinoza’s account of human bondage and human freedom indicate that Spinoza sees humans as beings that possess higher-order volitions, and that comments Spinoza makes throughout his corpus shows that he views beings that lack higher order desires to be, in an important sense, non-human. The analysis here sheds light upon the community of entities that Spinoza’s Ethics is written for, as well as upon issues concerning the nature of Spinoza’s Free Man.  相似文献

OBJECTIVE: Stress in pregnancy predicts earlier birth and lower birth weight. The authors investigated whether pregnancy-specific stress contributes uniquely to birth outcomes compared with general stress, and whether prenatal health behaviors explain this association. DESIGN: Three structured prenatal interviews (N = 279) assessing state anxiety, perceived stress, life events, pregnancy-specific stress, and health behaviors. MAIN OUTCOME MEASURES: Gestational age at delivery, birth weight, preterm delivery (<37 weeks), and low birth weight (<2,500 g). RESULTS: A latent pregnancy-specific stress factor predicted birth outcomes better than latent factors representing state anxiety, perceived stress, or life event stress, and than a latent factor constructed from all stress measures. Controlling for obstetric risk, pregnancy-specific stress was associated with smoking, caffeine consumption, and unhealthy eating, and inversely associated with healthy eating, vitamin use, exercise, and gestational age at delivery. Cigarette smoking predicted lower birth weight. Clinically-defined birth outcomes were predicted by cigarette smoking and pregnancy-specific stress. CONCLUSION: Pregnancy-specific stress contributed directly to preterm delivery and indirectly to low birth weight through its association with smoking. Pregnancy-specific stress may be a more powerful contributor to birth outcomes than general stress.  相似文献

The authors examined the effects that differently framed and targeted health messages have on persuading low-income women to obtain screening mammograms. The authors recruited 752 women over 40 years of age from community health clinics and public housing developments and assigned the women randomly to view videos that were either gain or loss framed and either targeted specifically to their ethnic groups or multicultural. Loss-framed, multicultural messages were most persuasive. The advantage of loss-framed, multicultural messages was especially apparent for Anglo women and Latinas but not for African American women. These effects were stronger after 6 months than after 12 months.  相似文献

Recent work on metacognition indicates that monitoring is sometimes based itself on the feedback from control operations. Evidence for this pattern has not only been shown in adults but also in elementary schoolchildren. To explore whether this finding can be generalized to a wide range of age groups, 160 participants from first to eighth grade participated in a study based on a self‐paced study time (ST) allocation paradigm. In contrast to previous studies, picture pairs instead of word pairs were used as stimuli to compensate for reduced reading skills in younger participants. Actual ST and judgments of learning (JOLs) made at the end of each study trial were used as core variables. The results are in line with previous findings, in that children's JOLs decreased with increasing ST, suggesting that JOLs were based on the memorizing effort heuristic that easily learned items are more likely to be remembered. Weaker inverse relationship between JOLs and ST was found for the younger children. Overall, these results underline the importance of mnemonic cues in shaping metacognitive feelings not only in adults but also in older children and expose a developmental trend in their use along childhood.  相似文献
