We examine the hypothesis that the efficiency of executive control processes is less stable over time in older than younger adults. An age-related decrease in the efficiency of executive control should result in an increase in performance variability in task conditions requiring the recruitment of executive control processes and not in task conditions requiring minimal involvement of executive control. Performance variability was similar for younger and older adults in task conditions requiring minimal executive control and greater for older than younger adults in task conditions requiring executive control. These and other data are consistent with the proposal that aging is associated with a decrease in the stability of executive control over time. 相似文献

To test the hypothesis that lower social status is associated with more smiling, the authors used newspaper photographs and their associated news stories as the basis for scoring the smiling and relative social status of the 2 individuals in each photograph. Independent raters judged smiling and 5 dimensions of relative status for 496 individuals in 248 newspaper photographs. There was no relation between status and smiling, although status and smiling were both related to other variables such as gender, age, and story valence. These findings add to a growing body of evidence that there is no generalized relation between smiling and status. 相似文献

A sizeable amount of research literature has failed to demonstrate a stable relationship between self-report and the Rorschach (Exner, 1993). However, principal component first-factor related test-interaction style has been shown to moderate convergence. In this study 78 psychiatric patients completed the Rorschach and the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Hathaway & McKinley, 1989). Practically no correlation was evident between the MMPI-2 and the Rorschach, measuring similar constructs, in all patients. Patients with similar test-interaction styles demonstrated positive intermethod correlations between both conceptually related and conceptually not directly related test indexes. The same scales were negatively correlated in patients with discordant test-interaction styles, and this difference between test-interaction style groups was significant. It is suggested that first-factor related test-interaction style moderates convergence. It is further suggested that test-interaction style moderates convergence between both conceptually related and conceptually not directly related measures of distress or psychopathology. 相似文献

Applying an eclectic psychoanalytic framework, this paper provides a thematic link between the core experiences of Williams' early life and his creative work. Both preoedipal and Oedipal themes are elucidated. The central issue that dominated Williams' mental life was his struggle between a sense of suffocation and confinement, on the one hand, and having artistic and sexual freedom, on the other. The experience of suffocation extended to his dread of becoming mad. This dread derived from his intense twinning or twinship merger with his schizophrenic sister who was confined in an asylum. The study focuses attention on a number of Williams' one-act and full-length plays, written during each of the decades of his public career, as representative of his overall dramatic opus. These works are indicative of his special relationship with his sister as well as of his obsession about self-indulgence and fear of confinement. The later plays suggest that he was subject to identity confusion. 相似文献

Drawing on Gollwitzer's deliberative–implemental mindset distinction (P. M. Gollwitzer, 1990), it was predicted that people who are deliberating on different actions or goals would be more cautious or more realistic in their expectation of success in subsequent tasks than people who are going to implement a chosen action or goal. Participants were given a choice between different test-materials. They were interrupted before (deliberative) or immediately after decision-making (implemental). They then either had to choose between various levels of difficulty within one type of task (Experiment 1) or they had to predict their own future performance (Experiment 2). The results showed that deliberative participants preferred less difficult tasks and overestimated their probability of success less than implemental participants. In addition, deliberative participants referred more than implemental participants to their past performance when selecting levels of difficulty or predicting future performance; however, the two groups did not differ in actual performance. Taken together, the findings suggest that people are more realistic in a deliberative than in an implemental state of mind. The present studies extend prior research because for the first time they document mindset effects on peoples' estimates concerning their future performance in the achievement domain. 相似文献

Previous studies have shown that source identification (ID) tests reduce, and in some cases eliminate, eyewitness suggestibility errors. The present study showed that the suggestibility errors participants committed on a source ID test were further reduced when they were given the explicit postwarning that the experimenter was trying to trick them. These postwarnings reduced suggestibility to the same extent as prewarnings, and they did so for both once and repeatedly suggested items. In addition, the benefits of the pre- and postwarnings persisted when participants were retested 1 week later, but only if the suggestions had been repeated. For once-suggested items, the warning had the unintended effect of improving old/new recognition of the suggested information at retest, an effect that offset the improvements in source discrimination accuracy conferred by the warning. The advantages of using source ID tests for investigating group differences in eyewitness suggestibility are discussed. 相似文献

It was hypothesized that participants who strongly identify with the ingroup and receive unfavorable feedback about their group in one domain would compensate on alternative dimensions. A group of emergency medical service volunteers received negative, positive or no feedback on their volunteer organization and were asked to rate the ingroup and an outgroup on dimensions alternative to the feedback. As predicted, high identifiers showed an increase in ingroup favoritism after negative feedback (i.e. compensation) and a decrease after positive feedback (i.e. modesty effect). In contrast, low identifiers distanced themselves from the ingroup after negative feedback and accentuated self‐ingroup similarity after positive feedback. Results are discussed in relation to a schema‐maintenance model through compensation (Seta & Seta, 1993 ) and social identity theory. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Diagnostic tests are available to detect several mutations related to adult-onset, autosomal dominant, neurodegenerative diseases.
We aimed to describe our experience in a presymptomatic testing program run by the Brazilian Public Health System from 1999
to 2009. A total of 184 individuals were eligible for presymptomatic testing due to a risk for spinocerebellar ataxia (SCA)
- SCA3 (80%), Huntington’s disease (11.9%), familial amyloidotic neuropathy (4.3%), SCA1, SCA2, SCA6, or SCA7. Most were women
(70%), married (54%), and had children prior to presymptomatic testing (67%). Their mean age at entrance was 34 (SD = 11 years).
Educational level was above the average Brazilian standard. After receipt of genetic counseling, 100 individuals (54%) decided
to undergo testing; of these, 51 were carriers. Since no individual returned for post-test psychological evaluation, we conducted
a subsequent survey, unrelated to test disclosures. We contacted 57 individuals of whom 31 agreed to participate (24 had been
tested, 7 had not). Several ascertainment concerns relating to these numerous losses prevented us from generalizing our results
from this second survey. We concluded that: decision-making regarding presymptomatic testing seems to be genuinely autonomous,
since after genetic counseling half the individuals who asked for presymptomatic testing decided in favor and half decided
against it; general characteristics of Brazilians who sought presymptomatic testing were similar to many European samples
studied previously; and individuals at risk for SCA3 may be at greater risk of depression. Although no clear-cut reason emerged
for rejection of follow-up psychological sessions after presymptomatic testing, this finding suggests adjustments to our presymptomatic
testing program are necessary. 相似文献

Using Italian data on Income and living conditions for the year 2005, the paper investigates the main determinants of households’
subjective economic well-being by means of a Partial Proportional Ordered Logit Model. According to a joint subjective and
objective perspective of analysis, we use as dependent variable the perceived ability of households to make ends meet. Whereas,
we use as explanatory variables some objective aspects of living conditions relating to housing, financial equilibrium, possession
of durables and quality of residence place and some socio-demographic characteristics. The empirical results show that the
financial strain is the most relevant dimension of living conditions influencing the subjective economic well-being, but its
effect is attenuated depending on the level of education and the tenure status of accommodation. Actually, when the highest
levels of education are coupled with the status of self-employee and house-owner households have more chances to reach a higher
probability to be economically satisfied. The insights coming out from the results may call for different policy measures
depending on the degree of well-being and the characteristics of households. In particular, more efficient policies would
be oriented to sustain the households’ income, to encourage to buy a house and to allow young people to get the highest levels
of education. 相似文献

While infants' ability to discriminate quantities has been extensively studied, showing that this competence is present even in neonates, the ability to compute ordinal relations between magnitudes has received much less attention. Here we show that the ability to represent ordinal information embedded in size-based sequences is apparent at 4months of age, provided that magnitude changes involve increasing relations. Infants in Experiments 1A and 1B discriminated changes in ordinal relations after habituation to ascending sequences, but did not show evidence of discrimination after habituation to descending sequences. In Experiment 2 we replicated this asymmetry in magnitude discrimination even when additional cues known to boost ordinal competence were provided. The presence of an asymmetry between ascending vs. descending order during infancy suggests a developmental continuity in the underlying code used to represent magnitude, whereby the reported addition advantage in children and adults' arithmetic performance emerges. 相似文献
