Instructions to attend to the case and color in which words were presented led to improved retention of these visual attributes but depressed recognition performance. This trade-off between item and attribute memory occurred at three presentation rates (1.5, 5.5, and 10.5 sec/item), suggesting that visual attributes of verbal stimuli are rarely stored unless subjects expect that knowledge of physical form will be useful later. Visual attributes of high-imagery words were retained better than visual attributes of low imagery words by subjects instructed to attend to case and color, but not by subjects asked only to attend to word meaning. Implications of these findings for the hypothesis that visually presented verbal stimuli are stored as literal copies are discussed. 相似文献

The disruptive behavior of a 9-yr-old boy was eliminated by the illumination of a light on the subject's desk, which represented the loss of free time later in the day. Instructions alone failed to reduce the frequency of disruptive behavior. When the light was removed and disruptive behavior no longer resulted in a loss of free time, disruptive behavior returned to its previous level. 相似文献

The introduction of a warning signal preceding shocks greatly increased the effectiveness of avoidance responding. Periods of “warm-up” at the beginning of the session were eliminated, and the number of shocks received by the subjects was greatly reduced. With response-shock interval constant, response rate increased as the interval between the response and the onset of the warning signal was shortened. The response tended to occur shortly after the onset of the warning signal regardless of the duration of these “safe” periods. A greatly elevated response rate was maintained even when the duration of the safe period was reduced to 0.3 sec. Thus, the pre-shock signal obtained nearly exclusive control of the responding and overrode the usual “temporal discrimination” of the response-shock interval. 相似文献

There is a limited amount of research that examines social-emotional functioning in children with Fetal Alcohol Spectrum Disorder (FASD), and the majority of it relies on parent and teacher reports of social impairments. Because these provide broad measures of social function, they fail to elucidate the underlying specific skills with which this group of children has difficulty. The current study examines emotion-recognition abilities in children with FASD, as it plays a central role in social interaction. Participants were 22 children with diagnosed FASD (ages 8–14), and age- and gender-matched typically developing controls. Tasks included measures of emotion recognition from three nonlinguistic modalities: facial expressions, emotional tone of voice, and body positioning and movement. Participant’s parents completed measures of adaptive and behavioral function that were related to children’s performance on aspects of emotion recognition. Overall, the results show that children with FASD have more difficulties with emotion recognition than typically developing age-matched peers, but these difficulties may not be clinically significant (e.g., smaller effect size) or may be specific to the age of the individual exhibiting the emotion (i.e., child vs. adult). These results are discussed in the context of previous studies. 相似文献

On the traditional view, moral distress arises only in cases where an individual believes she knows the morally right thing to do but fails to perform that action due to various constraints. We seek to motivate a broader understanding of moral distress. We begin by presenting six types of distress that fall outside the bounds of the traditional definition and explaining why they should be recognized as forms of moral distress. We then propose and defend a new and more expansive definition of moral distress and examine how it can enable the development of a taxonomy of moral distress. 相似文献

Children enjoy playing games. We can take advantage of this in the designs of computerized tasks that will engage their interest.
These designs also serve to advance the study of chronometric measures, such as manual and saccadic reaction times and event
related potentials, with young children. The goals of our method development are (1) to allow for comparable tasks across
a wide variety of ages, (2) to make possible comparisons of child performance with data gathered in adult cognitive studies,
and (3) to help to support inferences about the development of underlying mechanisms. We have designed a battery of computerized
tasks in order to study the development of attention functions of alertness, orienting, and executive control during childhood.
Our purpose is to describe each of these tasks in detail and present the results that have been obtained so far. The battery
was tested using a sample of 5-year-old children as subjects. 相似文献
