In this experiment, we tested children's intuitions about entities that bridge the contrast between living and non‐living things. Three‐ and four‐year‐olds were asked to attribute a range of properties associated with living things and machines to novel category‐defying complex artifacts (humanoid robots), a familiar living thing (a girl), and a familiar complex artifact (a camera). Results demonstrated that 4‐year‐olds tended to treat the category‐defying entities like members of the inanimate group, while 3‐year‐olds showed more variability in their responding. This finding suggests that preschoolers' ability to classify complex artifacts that cross the living–non‐living divide becomes more stable between the ages of 3 and 4 and that children at both ages draw on a range of properties when classifying such entities.  相似文献

The ability of children (M= 8.8 years) and adults (M= 25.6 years) to maintain task goals was examined by comparing their performance on a cued version of the Stroop colour‐word task. The experimental task presented a cue on each trial that instructed the participant to either read aloud the forthcoming word or name the colour of the word's lettering. Participants were tested with each of two cue‐stimulus delays (1,000 and 5,000 ms). Analysis of error rates in the colour‐naming condition revealed that children experienced greater interference than adults at each of the cue‐stimulus delays. In an effort to separate the relative contributions of colour‐naming and word‐reading processes, additional analyses were performed based on the process dissociation procedure of Lindsay and Jacoby (1994) . While colour‐naming process estimates did not vary with age group or cue‐stimulus delay, word‐reading process estimates were found to vary with age group and cue‐stimulus delay. Specifically, adults were superior to children in the inhibition of irrelevant word information only during a long cue‐stimulus delay. Collectively, these findings indicate that children have difficulty maintaining task goals in order to suppress stronger, goal‐irrelevant responses.  相似文献

ABSTRACT

Children and adolescents within refugee families face adverse childhood experiences emanating from multiple sources. These traumatic events can begin with persecution within their country of origin, during the migration process, and within their re-settled countries. More specifically, these children and their families are more prone to the four core stressors being: traumatic, acculturative, isolative and resettlement stress. Trauma Systems Therapy for Refugees (TST-R) is a promising treatment model to address child and adolescent mental health disparities revolving around direct and vicarious trauma. In TST-R, the treatment team systematically targets the needs of the child, while collaborating with cultural brokers from the refugee community, their school, and family unit. Researchers have used TST-R as an intervention for reducing trauma symptoms in Somali, Somali-Bantu, and Bhutanese children, adolescents, and their families. We review the strengths and limitations of this model. Further research is needed to determine its applicability to other communities within the United States and abroad.  相似文献

We examined the role of different facial features (shape of eyebrows, eyes, mouth, nose, and the direction of gaze) in conveying the emotional impact of a threatening face. In two experiments, a total of 100 high school students rated their impression of two sets of schematic faces in terms of semantic differential scales (Activity, Negative Evaluation, and Potency). It was found that the different facial features could be ordered hierarchically, with eyebrows as the most important feature, followed by mouth and eyes. Eyebrows thus fundamentally categorised faces as threatening or nonthreatening. The different shapes of mouth and eyes provided subsequent categorisations of faces within these primary categories.  相似文献

Suicidal thoughts and attempts have been studied from a number of perspectives, but only recently has an attempt been made to incorporate many different psychological perspectives into one framework. Baumeister (1990) has integrated personality and social psychological perspectives into one sequential model, moving from instigating events to a final stage of suicidal thoughts. Employing a sample of older adult subjects undergoing the stresses of a recent health downturn, this study tested a four-stage model of suicidal ideation based on many of the components proposed by Baumeister. Structural equation modeling achieved a good fit to the data. Results are discussed in terms of the importance of including life events, particularly poor health, and cognitive variables such as confusions in thinking, in understanding suicidal ideation.  相似文献
