The present research examined the developmental course of racial behaviours in childhood. It tested the hypothesis that White children's expressions of racial prejudice do not necessarily decline in middle childhood due to the development of particular cognitive skills but that instead, as argued by the socio-normative approach, children older than seven will go on expressing prejudiced attitudes under appropriate conditions. This would be explained by the presence of an anti-racism norm, along with the existence of values promoting equal rights, which impede blatant expressions of racism. In the first study 283 White children aged 6-7 and 9-10 years performed a task of resource allocation to White and Black target children in conditions of high (White interviewer was present) or low (White interviewer was absent) salience of the anti-racist norm. The 6- to 7-year-old children discriminated against the Black target in both conditions whereas older children discriminated against the Black child only when the anti-racist norm was not salient. In Study 2, 187 White children aged 6-7 and 9-10 years performed the same resource allocation task in conditions of explicit activation of similarity vs dissimilarity or egalitarian vs merit-based norms regarding race relations. Supporting the hypothesis of the role of racist or anti-racist norms on the expression of intergroup discrimination, results have again shown that 6- to 7-year-old children discriminated against the Black target in both conditions while older children presented significantly different prejudiced/nonprejudiced behaviours consistent with the activated norms. These results were discussed in terms of the need for a reanalysis of the assumptions and research results of the cognitive-developmental theory and of further developments in the socio-normative approach regarding the development of prejudice in childhood. 相似文献

This study examined the relationship between heart rate variability (HRV), as an index of individual differences in emotion
regulation, and perception of other-blame, as a mechanism of anger induction. The physiological responses were recorded while
subjects read a story from a computer screen. The story narrated a negative event in self-referred way -dismissal from a job
as the result of a colleague’s action- under conditions of intentionality versus non-intentionality. Cognitive and emotional
variables were assessed by questionnaire immediately after the physiological test. The resulting structural model supports
the conclusion that HRV exerts its regulatory influence directly on perception of other-blame rather than on emotion. In situations
of intentionality, individuals with higher HRV make less extreme evaluation of the offender’s blame, versus those with lower
HRV, thus leading to a reduction in anger reaction. These results suggest that HRV is a direct index of cognitive rather than
emotional regulation. 相似文献

Phonological and visual theories propose different primary deficits as part of the explanation for dyslexia. Both theories were put to test in a sample of Spanish dyslexic readers. Twenty-one dyslexic and 22 typically-developing children matched on chronological age were administered phonological discrimination and awareness tasks and coherent motion perception tasks. No differences were found between groups on the coherent motion tasks, whereas dyslexic readers were impaired relative to controls on phonological discrimination tasks. Gender differences followed the opposite pattern, with no differences on phonological tasks, and dyslexic girls performing significantly worse than dyslexic boys in coherent motion perception. These results point to the importance of phonological deficits related to speech perception in Spanish, and to possible gender differences in the neurobiological bases for dyslexia. 相似文献

This study explored the views of Mexican men and women concerning hysterectomy. We studied 120 women and 135 men between the ages of 36 and 55. Women had not had a hysterectomy and men were married to a woman without a hysterectomy. The most negative views about hysterectomy were women’s suppositions about male perceptions, but only among people with a limited educational background. This group was more likely to believe that women who undergo hysterectomy are incomplete, rejected by their partners, and experience emotional changes. These findings are discussed in light of sociocultural features. 相似文献

People often face preferential decisions under risk. To further our understanding of the cognitive processes underlying these preferential choices, two prominent cognitive models, decision field theory (DFT; Busemeyer & Townsend, 1993 ) and the proportional difference model (PD; González-Vallejo, 2002 ), were rigorously tested against each other. In two consecutive experiments, the participants repeatedly had to choose between monetary gambles. The first experiment provided the reference to estimate the models' free parameters. From these estimations, new gamble pairs were generated for the second experiment such that the two models made maximally divergent predictions. In the first experiment, both models explained the data equally well. However, in the second generalization experiment, the participants' choices were much closer to the predictions of DFT. The results indicate that the stochastic process assumed by DFT, in which evidence in favor of or against each option accumulates over time, described people's choice behavior better than the trade-offs between proportional differences assumed by PD. 相似文献

The present commentary addresses the main results obtained in the Butler and Klein [Butler, B. C., & Klein, R. (2009). Inattentional blindness for ignored words: Comparison of explicit and implicit memory tasks. Consciousness and Cognition, 18, 811–819.] study and discusses them in relation to the Perceptual Load Theory of Lavie [Lavie, N. (1995). Perceptual load as a necessary condition for selective attention. Journal of Experimental Psychology: Human Perception and Performance, 21, 451–68.]. The authors claim that the use of implicit indexes of conceptual distractor processing in high-load situations would be an important addition to the load literature, which would benefit the research field regardless of their positive or negative findings. 相似文献

To identify possible factors affecting the psychological impact of pre-symptomatic testing for spinocerebellar ataxia type
2 (SCA2) and familial amyloid polyneuropathy (FAP ATTRV30M), we studied (1) the effect of previous experience with the disease
in the family, (2) kinship with the closest affected relative and (3) gender of affected parent, when adapting to test results;
as well as (4) differences in the course of psychological wellbeing in 63 subjects ( 28 at-risk for FAP ATTRV30M, and 35 at
risk for SCA2), who pursued predictive testing for these diseases, in Cuba and in Portugal. Our research shows that individuals
with little or no experience with the disease in their family exhibited more anxiety; at-risk subjects for SCA2 or FAP ATTRV30M
who had a first degree relative with the disease showed lower levels of anxiety and depression during pre-symptomatic testing.
Also those with an affected mother had lower levels of depression, either immediately, or one year after receipt of test results.
Adaptation to pre-symptomatic testing results differed for subjects at-risk for the two different conditions. Unlike the FAP
ATTRV30M families, carriers for SCA2 reported pathological levels of depression immediately after-testing (3 weeks), although
those levels had returned to normal levels at 6 months. Subjects at-risk for FAP ATTRV30M tended to have less anxiety than
those tested for SCA2, at the one-year follow-up. Overall, depression levels improved over time, while anxiety remained more
constant. A longer awareness of the disease in the family, closer kinship, and a transmitting mother all lessened the impact
of pre-symptomatic testing, as expressed by the post-test levels of anxiety and depression. 相似文献

Many studies have suggested that a word’s orthographic form must be processed before its meaning becomes available. Some interpret
the (null) finding of equal facilitation after semantically transparent and opaque morphologically related primes in early
stages of morphological processing as consistent with this view. Recent literature suggests that morphological facilitation
tends to be greater after transparent than after opaque primes, however. To determine whether the degree of semantic transparency
influences parsing into a stem and a suffix (morphological decomposition) in the forward masked priming variant of the lexical
decision paradigm, we compared patterns of facilitation between semantically transparent (e.g., coolant—cool) and opaque (e.g., rampant—ramp) prime—target pairs. Form properties of the stem (frequency, neighborhood size, and prime—target letter overlap), as well
as related—unrelated and transparent—opaque affixes, were matched. Morphological facilitation was significantly greater for
semantically transparent pairs than for opaque pairs. Ratings of prime—target relatedness predicted the magnitude of facilitation.
The results limit the scope of form-then-meaning models of word recognition and demonstrate that semantic similarity can influence
even early stages of morphological processing. The research reported here was supported by National Institute of Child Health
and Development Grant HD-01994 to Haskins Laboratories. 相似文献
