The functional characteristics of visuo‐spatial serial memory and its sensitivity to irrelevant visual information are examined in the present study, through the investigation of the sandwich effect (e.g., ). The memory task was one of serial recall for the position of a sequence of seven spatially and temporally separated dots. The presence of irrelevant dots interpolated with to‐be‐remembered dots affected performance over most serial positions (Experiment 1) but that effect was significantly reduced when the interpolated dots were distinct from the to‐be‐remembered dots by colour and shape (Experiment 2). Parallels are made between verbal and spatial serial memory, and the reduction of the sandwich effect is discussed in terms of the contribution of perceptual organisation and attentional factors in short‐term memory. 相似文献

Whether fairness perceptions and leader trust mediate the relationship between leadership style and commitment and turnover was evaluated among Canadian Forces personnel (N = 1,443). Correlational analyses and structural equation modeling results provided support for the proposed meditational model. However, the influence of transactional leadership on commitment and turnover was due to its direct influence on fairness perceptions, whereas the influence of transformational leadership on these outcomes was based on its direct and indirect influence on both fairness perceptions and leader trust. It thus appears that both types of leadership style influence commitment and turnover, but the mechanism through which their effects occur may be distinct. The implications of these findings for theory, research, and practice are discussed. 相似文献

We examined liking for happy- and sad-sounding music as a function of exposure, which varied both in quantity (number of exposures) and in quality (focused or incidental listening). Liking ratings were higher for happy than for sad music after focused listening, but similar after incidental listening. In the incidental condition, liking ratings increased linearly as a function of exposure. In the focused condition, liking ratings were an inverted U-shaped function of exposure, with initial increases in liking (after 2 exposures) followed by decreases (after 8 or 32 exposures). The results documented that: (1) sad music is liked as much as happy music in some instances; (2) frequency of exposure causes both familiarity (positive) and over-familiarity (negative) effects; and (3) effects of exposure on liking differ for focused and incidental listening. 相似文献

AbstractThis meta-analytic review evaluates 35 parenting programs to analyze their effectiveness at reducing young children’s externalizing behavior (EB). It looks at whether behavioral or cognitive orientation, informant or duration of these programs moderate their effect on such young children. It confirms that parenting interventions are effective at decreasing young children’s EB but no moderation effect was found for specific orientation or duration, only for the informant. This illustrates the current difficulty in comparing programs on the basis of their theoretical background, which prevents the understanding of which are the most efficient parenting variables and change processes to manipulate. 相似文献

Researchers know relatively little about the normative development of children's behaviors aimed at alleviating distress or discomfort in others. In this article, the authors aim to describe the continuity and discontinuity in the degree to which young children in the general population are reported to exhibit specific prosocial behaviors. Data came from the Québec Longitudinal Study of Child Development. Consistent with Hay's model of prosocial development, the results show that there were about as many children who stopped exhibiting prosocial behaviors between 29 and 41 months of age as there were children who started doing so during this period. Further, gender differences (girls > boys) in prosocial behaviors are either emerging or at least increasing in magnitude, with girls being more likely to start and boys being more likely to stop exhibiting these behaviors between 29 and 41 months of age. Consistent with the early-onset hypothesis, children who exhibit prosocial behaviors at 17 months of age are less likely to stop exhibiting the same behaviors between 29 and 41 months of age. Otherwise, if they did not exhibit prosocial behaviors at 29 months of age, they are also more likely to start doing so in the following year. 相似文献

Mental retardation is a group of cognitive disorders with a significant worldwide prevalence rate. This high rate, together with the considerable familial and societal burden resulting from these disorders, makes it an important focus for prevention and intervention. While the diseases associated with mental retardation are diverse, a significant number are linked with disruptions in epigenetic mechanisms, mainly due to loss-of-function mutations in genes that are key components of the epigenetic machinery. Additionally, several disorders classed as imprinting syndromes are associated with mental retardation. This review will discuss the epigenetic abnormalities associated with mental retardation, and will highlight their importance for diagnosis, treatment, and prevention of these disorders. 相似文献

With the rapid shifts in the education of women in the United States, and the underrepresentation of women in fields of science, technology, engineering, and math (STEM), an issue generating much controversy is whether women may benefit more from single-sex education or coeducation. The present study surveyed 548 U.S. high-school boys and girls from single-sex and coeducational high-schools from the Midwest. Half of the participants completed a mathematics test under stereotype threat (ST) condition and half under no threat condition. Although girls in single-sex schools had higher achievement motive and self-esteem than those in coeducational schools, they were not more likely to pursue STEM careers. Overall, students in single-sex schools outperformed students from coeducational schools on the math test. Girls?? math performance was significantly higher in the ST condition than in the no threat condition. 相似文献
