When birds raised by another species become adults, they (if they are non-brood-parasitic species) usually attempt to mate
with birds of their foster species rather than with birds of their own species, a phenomenon called sexual imprinting. Avian
brood parasites lay their eggs in nests of other species (the hosts) that rear the young, but the problem of sexual imprinting
among brood parasites has generally been neglected, and brood parasites have been considered as an exception among birds.
Here, we show, with data from field observations and field experiments, firstly, that adult great spotted cuckoos Clamator glandarius sometimes maintain contact with both older nestling and fledgling cuckoos. Adult cuckoos visited parasitized nests during
the last days of the nestling period (5 observations) and, when parasitic chicks left the nest, adult cuckoos maintained contact
with the young (14 observations). Adults and fledgling cuckoos communicated vocally (5 observations), and an adult great spotted
cuckoo even fed a parasite fledgling in two cases. Secondly, when experimentally cross-fostered in nests of magpie Pica pica hosts outside the parasite breeding range (thus avoiding visual and acoustic communication with adult cuckoos), young cuckoos
did not learn to recognize their own species when only one cuckoo chick was introduced per nest, but they learnt to recognize
conspecifics when two cuckoos were reared together. This means that young great spotted cuckoos apparently must learn to recognize
conspecifics, that is, recognition is not innate. Social interactions between adult brood parasites and young have also been
reported in other brood parasites; thus, brood parasites are probably not an exception to the general phenomenon of imprinting,
and young brood parasites may need to be imprinted on conspecifics, although more studies on other brood parasite species
are needed to confirm this.

The ESPbase provides a tool for storing symbols and icons along with information about their characteristics. Information about a wide range of symbol characteristics is included on the database to facilitate the selection of symbol sets for research and design. The database includes information about the graphical characteristics and functions of symbols. It also includes ratings of symbol concreteness, complexity, familiarity, and meaningfulness. Symbols and icons can be accessed on the basis of each of these characteristics or any combination of characteristics. This makes it easier to select symbols on the basis of usability and design requirements. It also means that symbols can be easily selected for research while controlling their characteristics on a number of dimensions. 相似文献

The relation between spider fear in children and cognitive processing bias toward threatening information was examined. It was investigated whether spider fear in children is related to a cognitive bias for threatening pictures and words. Pictorial and linguistic Stroop stimuli were administered to 28 spider phobic and 30 control children aged 8–12. Spider-phobic children showed a moderate bias for threatening words. Surprisingly, no bias was found for spider pictures, while the spider-phobic children judged the pictures as more aversive. Moreover, in a recent similar study in adults (Kindt & Brosschot, 1997), a strong relation between spider phobia and bias toward threat words and pictures was found. Several explanations are given to account for this divergence. 相似文献

Longitudinal trajectories of bicultural identity integration in recently immigrated Hispanic adolescents: Links with mental health and family functioning 下载免费PDF全文

This study examined, in a sample of recently immigrated Hispanic adolescents in Miami and Los Angeles, the extent to which bicultural identity integration (BII; involving the ability to synthesise one's heritage and receiving cultural streams and to identify as a member of both cultures) is best understood as a developmental construct that changes over time or as an individual‐difference construct that is largely stable over time. We were also interested in the extent to which these trajectories predicted mental health and family functioning. Recent‐immigrant 9th graders (N = 302) were assessed 6 times from 9th to 12th grade. Latent class growth analyses using the first 5 timepoints identified 2 trajectory classes—one with lower BII scores over time and another with higher BII scores over time. Higher heritage and US identity at baseline predicted membership in the higher BII class. At the 6th study timepoint, lower BII adolescents reported significantly poorer self‐esteem, optimism, prosocial behaviour and family relationships compared with their higher BII counterparts. These findings are discussed in terms of further research on the over‐time trajectory of biculturalism, and on the need to develop interventions to promote BII as a way of facilitating well‐being and positive family functioning. 相似文献

ResumenSe llevó a cabo un experimento con vistas a estudiar el procesamiento de dibujos y de palabras en el marco de los paradigmas de Stroop y de anticipación. Las variables de tarea, modalidad y de relación semántica fueron equivalentes en ambos paradigmas. Según el intervalo temporal entre los estímulos se establecieron tres condiciones experimentales: condición previa—anticipación—, condición simultánea—Stroop—, y condición previa y simultánea—Stroop y anticipación—. Los resultados ponen de manifiesto la existencia de efectos de facilitación e interferencia de signo opuesto que se atribuyen a la interacción entre la secuencia temporal entre los estímulos componentes, las demandas de las respectivas tareas y la modalidad en la memoria activa. Los resultados se discuten en relación con el diferente procesamiento a que se someten los dibujos y las palabras y la naturaleza del formato de representación. 相似文献

The aim of this study was to investigate the role of discrete emotions in lexical processing and memory, focusing on disgust and fear. We compared neutral words to disgust-related words and fear-related words in three experiments. In Experiments 1 and 2, participants performed a lexical decision task (LDT), and in Experiment 3 an affective categorisation task. These tasks were followed by an unexpected memory task. The results of the LDT experiments showed slower reaction times for both types of negative words with respect to neutral words, plus a higher percentage of errors, this being more consistent for fear-related words (Experiments 1 and 2) than for disgust-related words (Experiment 2). Furthermore, only disgusting words exhibited a higher recall accuracy than neutral words in the memory task. Moreover, the advantage in memory for disgusting words disappeared when participants carried out an affective categorisation task during encoding (Experiment 3), suggesting that the superiority in memory for disgusting words observed in Experiments 1 and 2 could be due to greater elaborative processing. Taken together, these findings point to the relevance of discrete emotions in explaining the effects of the emotional content on lexical processing and memory. 相似文献

The purpose of the current study was to develop and evaluate a measure of maternal reward responsivity in parenting. Deficits in reward responsivity, a common feature of depression, may contribute to maladaptive parenting behaviors. Reward responsivity is an individual difference in reactivity to pleasurable stimuli and represents a key motivational component that could contribute to the frequency and quality of mothers’ interactions with their infants. However, there is currently no measure of reward responsivity in parenting, which would be necessary to evaluate the link between mother reward responsivity, behaviors towards their infant, and infant behavior. Therefore, the current study reports on the development and initial evaluation of a self-report measure of reward responsivity in parenting, the Mother Inventory of Reward Experience (MIRE). We evaluated the MIRE among 200 mothers (M?=?28.45, SD?=?5.50) recruited from a pediatric primary care center. After item analysis, 22 items were retained and displayed high internal consistency reliability and test re-test reliability. Convergent validity was established via a significant correlation with global reward responsivity. Concurrent validity was established via significant correlations with depressive symptoms, parenting stress, and child behavior problems. Incremental validity of the MIRE over a measure of global reward responsivity was supported. These results support the reliability and validity of the MIRE as a measure of reward responsivity in parenting. 相似文献

Virtuous arguers are expected to manifest virtues such as intellectual humility and open-mindedness, but from such traits the quality of arguments does not immediately follow. However, it also seems implausible that a virtuous arguer can systematically put forward bad arguments. How could virtue argumentation theory combine both insights? The solution, I argue, lies in an analogy with virtue epistemology: considering both responsibilist and reliabilist virtues gives us a fuller picture of the virtuous arguer. 相似文献
