The purpose of this study was to assess whether reaction time in persons with intellectual disabilities can be improved with an exercise program. 50 children and adolescents (M age = 14.7 yr., SD = 1.4, range = 11-18) with mild intellectual disability without Downs syndrome were randomly divided into control (20 boys, 5 girls) and experimental (19 boys, 6 girls) groups. The experimental group participated in a structured physical fitness program for 12 weeks. Reaction time was assessed at baseline and after 12 weeks. Significant improvements in reaction time were observed in the exercise group but not for the control group. Results indicated that reaction time can be improved with an exercise program in youth with intellectual disability. 相似文献

Cellular precipitation (also known as discontinuous precipitation) has been observed at the grain boundaries of a newly developed nickel-based Inconel740H alloy designed for use at 700?°C in advanced ultrasupercritical coal-fired power plants. By means of element mapping and selected area diffraction, the cellular precipitates were identified as Cr-rich M23C6 carbides. The onset of cellular precipitation was found to follow a pucker mechanism in Inconel740H. The cellular precipitates at the grain boundaries, even at low volume fractions, were severely detrimental to the creep strength at 750?°C. The creep rupture life of Inconel740H containing cellular precipitates at grain boundaries was only one-tenth of that for the alloy without cellular precipitates. The reason for the drastically decreased creep rupture life is attributed to the poor resistance of cellular precipitates to crack propagation during creep. 相似文献

William James conceptualized I, the self as subject as a stream of consciousness. When this conception is augmented with George Herbert Mead's view of self as a radically socialized and enculturated process, a result is the James-Mead model of dynamic self as a stream of enculturated consciousness. In this paper, we argue that connectionism is best suited to theorize this challenging notion. Based on the view that a connectionist model should describe psychological processes that carry out psychological functions grounded in a biological living system, we propose the I-SELF (Imitative and Sequence Learning Functional) model, which is designed to capture the temporal dynamics of a stream of consciousness whose content can be acquired via symbolically mediated social interaction with others in society. We identify four implications of the James-Mead model of dynamic self (embodiment, narrative and self, individual and collective self, and culture and self), and report computer simulations to show the utility of I-SELF in conceptualizing the dynamic self-processes in the contemporary social psychological literature. Theoretical and metatheoretical implications of the connectionist approach to self are discussed. 相似文献

Much research attention has been directed over the past twenty-five years to ethical issues in marketing. One area of marketing that is gaining research interest is the selling arena. Despite the extant literature on selling ethics, few studies have focused on identifying situations that pose ethical problems for field sales personnel. This paper reports results of an investigation that examined salespeople's perceptions concerning what selling situations or practices are ethical questions, what situations are presently addressed by company policies, and what situations should be addressed by company policies. Findings reveal that salespersons seemingly are desirous of receiving more management guidance than they currently are receiving regarding their ethical concerns. Implications for managers and researchers are provided. 相似文献

Although empirical work has examined differences between salesmen and saleswomen on various aspects, no comprehensive study has examined gender-based distinctions in salespeople's work motivation. The paucity of research attention on this topic is surprising given the plethora of literature in organizational behavior. This paper reports the results of an investigation that explored male and female salespeople's perceptions of expectancies, instrumentalities, and valence for rewards. Findings reveal minimal contrast between the two groups. Implications for practitioners and researchers are provided. 相似文献

Until the latter part of the 20th century, legal doctrines made it almost impossible to successfully prosecute in criminal court a case involving child sexual abuse (CSA), whether the complaint was timely or delayed. Many English-speaking countries have abrogated most formal legal barriers to prosecuting CSA cases, and courts are faced with the singular challenge of adjudicating sexual offenses against children that are reported to have happened years or decades earlier. We conducted analyses of 4,237 criminal complaints of CSA heard in Canadian criminal courts. There were several differences between timely and delayed prosecutions that led us to conclude that delayed prosecutions of CSA are common and due, in part, to the nature of the offense. Offense duration was associated with longer delays to prosecution. When the accused had access to the child through his position in the community, length of delay to prosecution was very long, particularly for male complainants. More research is needed on delayed CSA prosecutions, particularly given an apparent trend for jurisdictions to abolish barriers to criminal prosecutions of CSA that occurred years or decades earlier.

In this study, a priming Stroop paradigm was used to determine whether stereotype activation is unintentional. Priming conditions (priming/no‐priming) and the relationship between priming and target (consistent/inconsistent/no‐relation) were the independent variables; accuracy, reaction time and N400 amplitude were used as dependent variables. The reaction time revealed that stereotype activation is, to some extent, unintentional. Furthermore, the event‐related potenial (ERP) results showed that N400 amplitude was larger for inconsistent conditions than for consistent conditions. This result supported the notion that stereotype activation is an unintentional and automatic process. 相似文献
