This study used an emotional face stroop task to investigate the effects of self‐report trait anxiety, social concern (SC), and chronological age (CA) on reaction time to match coloured outlines of angry, happy, and neutral faces (and control faces with scrambled features) with coloured buttons in a community sample of 74 children aged 6 –12 years. The results showed an interference of colour matching for angry (relative to neutral) faces in children with elevated SC. The same effect was not found for happy or control faces. In addition, the results suggest that selective attention to angry faces in children with social concern (SC) was not significantly moderated by age. 相似文献

Memory discrimination for self-performed and imagined acts: Bizarreness effects in false recognition
James B. Worthen Virginia V. Wood 《The Quarterly Journal of Experimental Psychology Section A: Human Experimental Psychology》2001,54(1):49-67
Two experiments investigated the susceptibility of common and unusual action events to memory distortion under incidental learning and delayed testing conditions. Experiment 1 tested the influence of imaginal and enactment instructions at testing on memory discrimination for self-performed and imagined acts. The influence of hypnotic procedures at testing on memory discrimination for action events was tested in Experiment 2. The results of both experiments suggest that the likelihood of confusing details associated with separate, previously experienced unusual action events is greater than the likelihood of confusing details associated with separate, previously experienced common action events. Based on the results of both experiments, it is concluded that bizarreness has both memory-facilitating and memory-inhibiting qualities. 相似文献

The present study examined rats' responding on a differential-reinforcement-of-low-rates schedule of food reinforcement following intraperitoneal injections of various doses of bombesin (4, 6, 8, 16, 32 micrograms/kg). Analyses indicated that only the 6 micrograms/kg dosage improved DRL responding. The findings are consistent with prior research examining bombesin's effect on operant behavior and support the notion that bombesin induces satiety rather than malaise. 相似文献

Variation in how frequently caregivers engage with their children is associated with variation in children's later language outcomes. One explanation for this link is that caregivers use both verbal behaviors, such as labels, and non-verbal behaviors, such as gestures, to help children establish reference to objects or events in the world. However, few studies have directly explored whether language outcomes are more strongly associated with referential behaviors that are expressed verbally, such as labels, or non-verbally, such as gestures, or whether both are equally predictive. Here, we observed caregivers from 42 Spanish-speaking families in the US engage with their 18-month-old children during 5-min lab-based, play sessions. Children's language processing speed and vocabulary size were assessed when children were 25 months. Bayesian model comparisons assessed the extent to which the frequencies of caregivers’ referential labels, referential gestures, or labels and gestures together, were more strongly associated with children's language outcomes than a model with caregiver total words, or overall talkativeness. The best-fitting models showed that children who heard more referential labels at 18 months were faster in language processing and had larger vocabularies at 25 months. Models including gestures, or labels and gestures together, showed weaker fits to the data. Caregivers’ total words predicted children's language processing speed, but predicted vocabulary size less well. These results suggest that the frequency with which caregivers of 18-month-old children use referential labels, more so than referential gestures, is a critical feature of caregiver verbal engagement that contributes to language processing development and vocabulary growth.
Research Highlights
- We examined the frequency of referential communicative behaviors, via labels and/or gestures, produced by caregivers during a 5-min play interaction with their 18-month-old children.
- We assessed predictive relations between labels, gestures, their combination, as well as total words spoken, and children's processing speed and vocabulary growth at 25 months.
- Bayesian model comparisons showed that caregivers’ referential labels at 18 months best predicted both 25-month vocabulary measures, although total words also predicted later processing speed.
- Frequent use of referential labels by caregivers, more so than referential gestures, is a critical feature of communicative behavior that supports children's later vocabulary learning.
