Life span researchers have long been interested in how and why fundamental aspects of human ontogeny differ between cohorts of people who have lived through different historical epochs. When examined at the same age, later born cohorts are often cognitively and physically fitter than earlier born cohorts. Less is known, however, about cohort differences in the rate of cognitive aging and if, at the very end of life, pervasive mortality-related processes overshadow and minimize cohort differences. We used data on 5 primary mental abilities from the Seattle Longitudinal Study (Schaie, 2005) to compare both age-related and mortality-related changes between earlier born cohorts (1886-1913) and later born cohorts (1914-1948). Our models covary for several individual and cohort differences in central indicators of life expectancy, education, health, and gender. Age-related growth models corroborate and extend earlier findings by documenting level differences at age 70 of up to 0.50 SD and less steep rates of cognitive aging on all abilities between 50 and 80 years of age favoring the later born cohort. In contrast, mortality-related models provide limited support for positive cohort differences. The later born cohort showed steeper mortality-related declines. We discuss possible reasons why often reported positive secular trends in age-related processes may not generalize to the vulnerable segment of the population that is close to death and suggest routes for further inquiry. 相似文献

The accuracy with which adults who do not stutter predict stuttering-related communication attitudes
The purpose of this study was to examine the extent to which adults who do not stutter can predict communication-related attitudes of adults who do stutter. 40 participants (mean age of 22.5 years) evaluated speech samples from an adult with mild stuttering and an adult with severe stuttering via audio-only (n = 20) or audio-visual (n = 20) modes to predict how the adults had responded on the S24 scale of communication attitudes. Participants correctly predicted which speaker had the more favorable S24 score, and the predicted scores were significantly different between the severity conditions. Across the four subgroups, predicted S24 scores differed from actual scores by 4–9 points. Predicted values were greater than the actual values for 3 of 4 subgroups, but still relatively positive in relation to the S24 norm sample. Stimulus presentation mode interacted with stuttering severity to affect prediction accuracy. The participants predicted the speakers’ negative self-attributions more accurately than their positive self-attributions. Findings suggest that adults who do not stutter estimate the communication-related attitudes of specific adults who stutter in a manner that is generally accurate, though, in some conditions, somewhat less favorable than the speaker's actual ratings. At a group level, adults who do not stutter demonstrate the ability to discern minimal versus average levels of attitudinal impact for speakers who stutter. The participants’ complex prediction patterns are discussed in relation to stereotype accuracy and classic views of negative stereotyping.Educational objectives: The reader will be able to (a) summarize main findings on research related to listeners’ attitudes toward people who stutter, (b) describe the extent to which people who do not stutter can predict the communication attitudes of people who do stutter; and (c) discuss how findings from the present study relate to previous findings on stereotypes about people who stutter. 相似文献

In addition to the negative effects of economic inequality on a range of health and social outcomes, we propose that inequality should also affect how people perceive the broader normative climate in society. We predicted that people living in a more unequal (vs. equal) society are more likely to appraise the social context as one where individualism determines people's behavior. We tested this idea in three experiments by manipulating the degree of economic inequality in a fictional society. We showed that, compared to the low-inequality condition, participants in the high-inequality condition were more likely to project individualistic norms onto society. Furthermore, Experiments 2 and 3 showed that in the high- (vs. low-) economic-inequality condition, participants inferred more competition and less cooperation between people. Our results are discussed in light of the importance of the perception of a broader normative climate to explain the consequences of economic inequality. 相似文献

In organizational psychology, staff perceptions of organizational climate have been found to be an important predictor of employee outcomes, such as employee stress. However, only a small pool of research has investigated the psychological mechanism that underpins the relationship, and no past literature has explored how the relationship persists over time. This paper uses the social identity approach to investigate whether social identification predicts and mediates the relationship between staff perceptions of organizational climate and their levels of stress and self-esteem over time. Employing a sample of public school teachers, the study was conducted over two years (N = 281, 65 schools). The results indicated that social identification fully mediated the relationship between organizational climate and self-esteem longitudinally but showed no significant relationship with stress. The implications of these findings are discussed, with recommendations for future research. 相似文献

Enhancing the Cognitive Vitality of Older Adults 总被引:1,自引:0,他引:1
Aging is associated with decline in a multitude of cognitive processes and brain functions. However, a growing body of literature suggests that age-related decline in cognition can sometimes be reduced through experience, cognitive training, and other interventions such as fitness training. Research on cognitive training and expertise has suggested that age-related cognitive sparing is often quite narrow, being observed only on tasks and skills similar to those on which individuals have been trained. Furthermore, training and expertise benefits are often realized only after extensive practice with specific training strategies. Like cognitive training, fitness training has narrow effects on cognitive processes, but in the case of fitness training, the most substantial effects are observed for executive-control processes. 相似文献

This study examined the psychometric properties of the Sutter-Eyberg Student Behavior Inventory (SESBI) in a rural sample of children and adolescents. Thirty-eight 5th- through 12th-grade teachers completed the SESBI on 726 children in their classrooms. High Cronbach's alphas supported the reliability of the SESBI scales in this population. Higher SESBI scores were obtained by boys than girls and by African American students than Caucasian students, more so at lower grades. Teacher's race did not affect SESBI scores. In contrast to children with developmental delay, children with learning disabilities obtained higher scores than others on the SESBI Intensity scale but not on the Problem scale. This suggests that teachers of children with learning disabilities recognize the higher frequency of problem behaviors in their students but do not consider these behaviors to be problems for themselves. On both SESBI scales, children with developmental delay were not distinguishable from peers without developmental delays. 相似文献

The author extended the proposition (V. J. Derlega, R. J. Lewis, S. Harrison, B. A. Winstead, & R. Costanza, 1989) that the fear of being seen as homosexual accounts for the common finding that U.S. women engage in more same-sex touch than do U.S. men. The author proposed a theoretic model positing that the magnitude of homophobia's influence on behavior and on reactions to behavior is proportional to the likelihood that the behavior is sexual in nature. An experiment involving reactions to same-sex embraces demonstrated that, although homophobia was negatively related to evaluations of same-sex affectionate touch, the magnitude of the relationship covaried with the probability that the touch was sexual. The implications of these findings for longer range theory development are discussed. 相似文献

Many patients with frontotemporal dementia (FTD) have impaired sentence comprehension. However, the pattern of comprehension difficulty appears to vary depending on the clinical subgroup. The purpose of this study was to elucidate the neural basis for these deficits in FTD. We studied patients with two different presentations: Three patients with Progressive Non-Fluent Ahasia (PNFA), and five non-aphasic patients with a dysexecutive and social impairment (EXEC). The FTD patient subgroups were compared to a cohort of 11 healthy seniors with intact sentence comprehension. We monitored regional cerebral activity with blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) while subjects read sentences featuring both a grammatically complex object-relative center-embedded clause and a long linkage between the head noun phrase (NP) and the gap where the NP is interpreted in the center-embedded clause. Subjects decided whether the agent of the action is a male or a female. Healthy seniors activated both ventral portions of inferior frontal cortex (vIFC) and dorsal portions of IFC (dIFC) in the left hemisphere, often associated with grammatical and working memory components of these sentences, respectively. PNFA patients differed from healthy controls since they have reduced activation of left vIFC, while EXEC patients have less recruitment of left dIFC. We conclude that FTD subgroups have distinct patterns of sentence comprehension difficulty in part because of selective interruptions of a large-scale neural network for sentence processing. 相似文献

Traditionally, African Americans have registered lower rates of suicide than other ethnic groups. In the last 20 years this pattern has changed, particularly among young African Americans. To date, the research conducted regarding this phenomenon has been limited for a variety of reasons and previous research has been inconclusive in determining risk factors of African American suicide. The purpose of this paper is to identify risk and protective factors specific to African American suicide. To determine the factors, the 1993 National Mortality Follow-back Survey was analyzed. The risk factors identified include being under age 35, southern and northeastern residence, cocaine use, firearm presence in home, and threatening others with violence. Some of the protective factors associated with African American suicide include rural residence and educational attainment. These results provide valuable information about completed African American suicides in relation to Whites. Several of these factors are unique to African Americans. 相似文献

The social meaning model asserts that some nonverbal behaviors have consensually recognized relational meanings within a given social community. According to this perspective, the interpretations made by encoders, decoders, and 3rd-party observers of the same nonverbal behavior should be congruent. The authors applied the model to the identification of relational message interpretations of nonverbal matching behavior. Confederates either matched or did not match the nonverbal behaviors of conversational participants while being watched by nonparticipant observers. All three nonconfederate participants provided interpretations of the confederates' relational messages. As the authors had expected, there were moderate correlations between the 3 perspectives, with observers usually providing less favorable assessments than the conversational participants. The authors also examined the influence of positive and negative stimulus behavior on relational message interpretations. 相似文献
