Many decisions related to cigarette smoking require people in an affectively neutral, or "cold," state to predict how they will feel or behave when in a craving, or "hot," state. Research in other domains has revealed that individuals in cold states often underestimate the impact of being in a hot state on their own future behavior. In a study testing whether this is true of cigarette craving, 98 smokers were assigned to one of three conditions: hot (during a high-craving first session, they made predictions about a high-craving state in a second session), cold (during a low-craving first session, they made predictions about a high-craving state in a second session), and comparison (they experienced a high-craving session only). As predicted, in contrast to smokers in the hot group, smokers in the cold group underpredicted the value they would place on smoking during the second session. Results support the existence of a cold-to-hot empathy gap in smokers and help to explain diverse aspects of tobacco addiction. 相似文献

Gestational cocaine treatment results in significantly increased maternal aggression towards an intruder by postpartum day six, while acute postpartum treatment dose dependently decreases maternal aggressive (MA) behavior. Both increased and decreased aggression in the cocaine-treated dams are correlated with either decreased or increased levels of oxytocin in the amygdala, respectively. The current study was an effort to determine whether the effect of gestational cocaine on maternal aggression is transient or would continue into the postpartum period; whether an intermittent cocaine treatment regimen, which incorporates gestational and postpartum intermittent cocaine treatment, would differ from chronic daily gestational treatment; and finally, whether next generation female offspring of cocaine-treated or control dams would have altered MA behavior and oxytocin system changes attributable to either prenatal drug exposure, rearing condition or both. We now report no increase in maternal aggression following chronic gestational treatment and significantly lower levels of aggression in intermittently treated dams on postpartum day eight, with no significant effects in either group on postpartum day 12. Young adult female offspring of the cocaine-treated and control dams, who reared their own natural litters and were tested on postpartum day eight for maternal aggression, had higher levels of maternal aggression towards an intruder attributable to both prenatal cocaine exposure and rearing condition. Higher aggression in cocaine-reared next generation dams was associated with lower levels of oxytocin in the amygdala. Intergenerational effects of cocaine were apparent with respect to aggression and oxytocin system changes. 相似文献

The conventional wisdom about the relationship between immigration and national electoral politics in Canada, albeit based on limited research, is that immigration is non-partisan and does not feature prominently during election campaigns. This paper examines the last two federal elections, in 2004 and 2006, employing a multi-pronged approach to party platform, media and survey analysis, in order to determine if immigration is discussed and, if so, how. It finds a political debate does take place but is not easily discernible using traditional research methods. This discourse is framed in terms of alternatives of inclusion, and not exclusion, something facilitated by the complexity of the Canadian immigration programme and the geographical and political landscape, and appears to be especially evident during more competitive elections. 相似文献

The self-reporting of cancer history is becoming increasingly important, as it frequently guides medical decision-making.
We studied the accuracy of personal cancer history using a self-administered questionnaire, comparing the results with the
Tumor Registry at our institution. Among 39,662 records, we identified 3614 women with a single cancer in the Tumor Registry
who reported none or one cancer on their questionnaire. The sensitivity in self-reporting cancers was 85.7%, ranging from
92.1% for breast cancer to 42.9% for leukemia. The accuracy for breast cancer and Hodgkin's Lymphoma was significantly better
than other cancers (p=0.00027, CI: 1.4–3.88). Analysis of patient's characteristics showed that Caucasians reported breast cancer more accurately
than Asian/Pacific Islanders (p=0.008), and those with Jewish ancestry more accurately than non-Jewish (p=0.0435). These results will help us to improve data collection and thus improve medical decision-making. 相似文献

This study examined the sensitivity and false-positive error rate of reliable digit span (RDS) and the WAIS-III Digit Span (DS) scaled score in persons alleging toxic exposure and determined whether error rates differed from published rates in traumatic brain injury (TBI) and chronic pain (CP). Data were obtained from the files of 123 persons referred for neuropsychological evaluation related to alleged exposure to environmental and industrial substances. Malingering status was determined using the criteria of Slick, Sherman, and Iverson (1999). The sensitivity and specificity of RDS and DS in toxic exposure are consistent with those observed in TBI and CP. These findings support the use of these malingering indicators in cases of alleged toxic exposure and suggest that the classification accuracy data of indicators derived from studies of TBI patients may also be validly applied to cases of alleged toxic exposure. 相似文献

Limb apraxia is a neurological disorder of higher cognitive function characterized by an inability to perform purposeful skilled
movements and not attributable to an elementary sensorimotor dysfunction or comprehension difficulty. Corticobasal Syndrome
(CBS) is an akinetic rigid syndrome with asymmetric onset and progression with at least one basal ganglia feature (rigidity,
limb dystonia or myoclonus) and one cortical feature (limb apraxia, alien hand syndrome or cortical sensory loss). Even though
limb apraxia is highly prevalent in CBS (70–80%), very few studies have examined the performance of CBS patients on praxis
measures in detail. This review aims to (1) briefly summarize the clinical, neuroanatomical and pathological findings in CBS,
(2) briefly outline what limb apraxia is and how it is assessed, (3) to comprehensively review the literature on limb apraxia
in CBS to date and (4) to briefly summarize the literature on other forms of apraxia, such as limb-kinetic apraxia and buccofacial
apraxia. Overall, the goal of the review is to bring a model-based perspective to the findings available in the literature
to date on limb apraxia in CBS. 相似文献

The authors offer an integral approach to counseling ethics using K. Wilber's (2000a, 2000b) integral metatheory. The article examines traditional counseling ethics through the lens of K. Wilber's (2000a, 2000b) “all‐quadrants, all‐levels” model, consisting of quadrants, levels, lines, states, and types. The authors begin with the 4 quadrants and how they can inform understanding of traditional counseling ethics. Vertical development in relation to counseling ethics is addressed, followed by a case study of an ethical dilemma in counseling. The authors offer an integrally informed process of ethical decision making that can be seen to complement less comprehensive ethical decision‐making models. 相似文献
