Identification of distinct units within a continuous flow of human action is fundamental to action processing. Such segmentation
may rest in part on statistical learning. In a series of four experiments, we examined what types of statistics people can
use to segment a continuous stream involving many brief, goal-directed action elements. The results of Experiment 1 showed no evidence for sensitivity to conditional probability, whereas Experiment 2 displayed learning based on joint probability. In Experiment 3, we demonstrated that additional exposure to the input failed to engender sensitivity to conditional probability. However,
the results of Experiment 4 showed that a subset of adults—namely, those more successful at identifying actions that had been seen more frequently than
comparison sequences—were also successful at learning conditional-probability statistics. These experiments help to clarify the mechanisms subserving processing
of intentional action, and they highlight important differences from, as well as similarities to, prior studies of statistical
learning in other domains, including language. 相似文献

This study investigated how assistive reading software affected the reading performance of a group of 20 post-secondary students
who had a primary diagnosis of attention disorder. These students used assistive reading software for most of a semester to
read assignments for an English class and in testing sessions in which comparisons were made between normal, unassisted reading,
and reading assisted by the soft ware. This software provides a synchronized visual and auditory presentation of text, and
incorporates study skills tools for highlighting and note taking. Attention measures, reading speed, comprehension scores,
and attitude questionnaire responses were obtained during these sessions. The principal findings were that the assistive software
allowed the students to attend better to their reading, to reduce their distractibility, to read with less stress and fatigue,
and to read for longer periods of time. It helped them to read faster and, thereby, to complete reading assignments in less
time. It did not have a significant effect on comprehension, but it helped some students whose comprehension was very poor.
The study results indicate that assistive reading software should be considered as a significant intervention to assist students
who have attention disorders and as an accommodation to help them compensate for their disabilities. 相似文献

Re-referral to child protective services: the influence of child, family, and case characteristics on risk status 总被引:2,自引:0,他引:2
INTRODUCTION: This study examines child, family, and case characteristics that impact rates of re-referral to Child Protective Services (CPS) using data on all closed CPS investigations for the state of Rhode Island between 2001 and 2004. METHOD: A longitudinal dataset of all referrals to CPS was created using state submissions to the National Child Abuse and Neglect Data System (NCANDS). After excluding children whose initial CPS investigation resulted in removal from the home, a Cox proportional hazards model was tested to examine factors impacting the likelihood of re-referral. RESULTS: Consistent with other research in this area, the initial 6-month period following case disposition is the period of greatest risk of re-referral. Approximately 13% of cases experienced a recurrent allegation during the first 6-month period; an additional 14% experienced a re-referral over the following 12-month period; 7% during the next 12-month period. Family poverty was the strongest predictor of re-referral, though a number of child and case characteristics were significantly related to recurrence. Cases that were substantiated at index were significantly less likely to result in a new allegation, though substantiated cases of physical abuse or those receiving post-investigation services were at higher risk. CONCLUSIONS: Children from families facing multiple stressors (e.g., low SES, parental substance abuse child disability) are at highest risk of re-referral to CPS and may benefit from the development of preventive services targeted immediately following case closings within CPS. 相似文献

ObjectivesThis study examined risk of maltreatment among children exiting foster care using a statewide sample of children reunified between 2001 and 2004 in Rhode Island. The objectives were: (1) to compare rates of maltreatment following parental reunification for youth in care as a result of maltreatment with those in care for other reasons; and (2) to assess the effects of child, family, and case characteristics on rates of re-maltreatment among children placed in foster care due to maltreatment.MethodA longitudinal dataset of all reunified cases was matched with state records of substantiated Child Protective Service (CPS) investigations. Two Cox proportional hazards models were tested. The first model compared rates of subsequent maltreatment for two groups: children in foster care as a result of maltreatment, and those in care for other reasons. The second model investigated the effects of child, family, and case characteristics on re-maltreatment rates for those in care as a result of maltreatment.ResultsChildren in foster care due to maltreatment were significantly more likely to be maltreated following reunification. Among children in foster care due to maltreatment, factors that raised risk for re-maltreatment included a previous foster care placement, exiting care from a non-relative foster home, and removal due to neglect. Older adolescents had lower rates of re-maltreatment than infants. Child neglect was the primary type of recurrent maltreatment that occurred following reunification.ConclusionsSupports are needed for families about to be reunified, particularly when the removal was prompted by incidents of abuse or neglect. Incidents of neglect are particularly likely and appropriate services should specifically target factors contributing to neglect. Cases involving youth with a history of repeated foster care placement or in which non-relative placements are utilized may need additional supports.Practice implicationsThis study suggests that services should be developed to minimize the risk for recurrent maltreatment following reunification. Services would be most useful for high-risk cases prior to reunification and during the first year following reunification. Understanding the risks associated with maltreatment will help guide development of appropriate interventions. 相似文献
