Ecological validity of neuropsychological assessment: Do neuropsychological indexes predict performance in everyday activities?

This paper discusses the nature of neuropsychological assessment within the context of ecological validity. It considers the extent to which traditional neuropychological tests can predict performance in everyday life before going on to describe several new procedures designed to map directly on to real life functioning.     

判断与决策中的基线比例忽略

基线比例忽略是指在事件的判断中忽略相关事件统计学上的信息, 而只关注当前呈现的案例信息, 从而造成判断和决策偏差的一种现象。目前对这一现象的解释主要包括双加工理论和线性整合理论, 而影响基线比例忽略的因素有许多方面, 如信息特征、认知能力等等。在未来研究中, 应该深入分析双加工理论的作用机制以及依据模糊痕迹理论提出新的研究视角, 同时拓展在团体和公共领域中的应用性研究。     

Dual-memory processes in crack cocaine dependents: The effects of childhood neglect on recall

Exposure to adversities during sensitive periods of neurodevelopment is associated with the subsequent development of substance dependence and exerts harmful, long-lasting effects upon memory functioning. In this study, we investigated the relationship between childhood neglect (CN) and memory using a dual-process model that quantifies recollective and non-recollective retrieval processes in crack cocaine dependents. Eighty-four female crack cocaine–dependent inpatients who did (N = 32) or did not (N = 52) report a history of CN received multiple opportunities to study and recall a short list composed of familiar and concrete words and then received a delayed-recall test. Crack cocaine dependents with a history of CN showed worse performance on free-recall tests than did dependents without a history of CN; this finding was associated with declines in recollective retrieval (direct access) rather than non-recollective retrieval. In addition, we found no evidence of group differences in forgetting rates between immediate- and delayed-recall tests. The results support developmental models of traumatology and suggest that neglect of crack cocaine dependents in early life disrupts the adult memory processes that support the retrieval of detailed representations of events from the past.     

Children with Disabilities

Abstract

Children in out-of-home care due to abuse and neglect are at disproportionately high risk for disabling conditions. The reasons for the over-representation of children with disabilities in the child welfare system are reviewed and discussed in this chapter. Factors discussed include impact of abuse and neglect, the impact risk factors such as exposure to community and domestic violence and poverty, risk of abuse or neglect associated with disability, and child welfare system factors. In addition, the need for greater efficacy in identification of disability, identification of service needs, and linkage with and delivery of services to serve the needs of children with disabilities in out-of-home care is addressed. Recommendations for policy review at State and Federal levels are offered along with direction for future research.     

Preface

Abstract

Child victimization is a serious and on-going problem in the United States and throughout the world. In 2000, an estimated 900,000 children were victims of abuse and neglect in the United States. New and different responses to child maltreatment will have to be developed and implemented in response to the increasingly diverse contexts and situations within which maltreatment occurs. Emerging trends in adult-child boundary violations are explored within this volume from a cross-section of disciplines, including law, sociology, criminal justice, psychology, and health services. The selections analyze issues critical to child maltreatment and offer intriguingly different perspectives of present and future issues related to child abuse.     

What We Know—and Don't Know—About Preventing Child Maltreatment

Abstract

Although child maltreatment is routinely acknowledged as a serious social problem, it remains widespread, raising questions about how prevention efforts can be improved. Following a review of theory and research relevant to prevention programming, the two dominant models of child abuse prevention-child empowerment and parent education-are examined, emphasizing both those factors that appear to contribute to program success (e.g., early intervention, sufficient time commitments, cultural sensitivity) and weaknesses in current efforts (e.g., poor implementation). Although underutilized, broader social and system-level reforms, including social policy and media initiatives, hold promise for prevention. Ways in which to leverage these tools are explored. Additional research is urged to explore assumptions on which programs are based, as well as to conduct more rigorous evaluation of current programs. The article concludes that a sustained commitment to prevention efforts aimed at child abuse and neglect is required.     

To what extent do we process the nondominant object in a morphed figure? Evidence from a picture–word interference task

Since the 1970s, the Heuristics and Biases Program in Cognitive Psychology has shown that people do not reason correctly about conditional probability problems. In the 1990s, however, evolutionary psychologists discovered that if the same problems are presented in a different way, people's performance greatly improves. Two explanations have been offered to account for this facilitation effect: the natural frequency hypothesis and the nested-set hypothesis. The empirical evidence on this debate is mixed. We review the literature pointing out some methodological issues that we take into account in our own present experiments. We interpret our results as suggesting that when the mentioned methodological problems are tackled, the evidence seems to favour the natural frequency hypothesis and to go against the nested-set hypothesis.
