In grapheme-color synesthesia, graphemes (e.g., numbers or letters) evoke color experiences. It is generally reported that the opposite is not true: colors will not generate experiences of graphemes or their associated information. However, recent research has provided evidence that colors can implicitly elicit symbolic representations of associated graphemes. Here, we examine if these representations can be cognitively accessed. Using a mathematical verification task replacing graphemes with color patches, we find that synesthetes can verify such problems with colors as accurately as with graphemes. Doing so, however, takes time: ~250 ms per color. Moreover, we find minimal reaction time switch-costs for switching between computing with graphemes and colors. This demonstrates that given specific task demands, synesthetes can cognitively access numerical information elicited by physical colors, and they do so as accurately as with graphemes. We discuss these results in the context of possible cognitive strategies used to access the information.  相似文献

The aim of this study was to identify factors contributing to clinician time spent in non-reimbursable activity on an inpatient pediatric consultation–liaison (C–L) service. A retrospective study was conducted using inpatient C–L service data on 1,246 consecutive referrals. For this patient population, the strongest predictor of level of non-reimbursable clinical activity was illness chronicity and the number of contacts with C–L service clinicians during their hospital stay. Patients with acute life-threatening illnesses required the highest mean amount of non-reimbursable service activity. On average, 28 % of total clinician time in completing a hospital consultation was spent in non-reimbursable activity. Effective C–L services require a proportion of time spent in non-reimbursable clinical activity, such as liaison and coordinating care with other providers. Identifying referral and systemic factors contributing to non-reimbursable activity can provide insight into budgeting/negotiating for institutional support for essential clinical and non-clinical functions in providing competent quality patient care.  相似文献

The authors randomly assigned 69 undergraduates to 1 of 2 perceptual priming conditions involving 80-ms flash words presented on a computer screen to activate information processing outside of conscious awareness. In the high-prime condition, the authors exposed participants to stereotype words associated with the Yellow Peril view of Asian Americans. The authors exposed participants in a low-prime condition to neutral words. All participants then read a vignette and evaluated its protagonist on several social dimensions. Results indicated that the priming procedure effectively biased participant evaluation of the vignette target, but only on items closely linked to Asian Americans. Contrary to predictions, however, participants in the high-prime group rated the target less Asian than did their low-prime group counterparts, an apparent reversal of the expected priming effect. The authors discussed theoretical implications.  相似文献

Hooking up on college campuses has become more frequent than dating in heterosexual sexual interaction. Analysis of the relative benefits and costs associated with dating and hooking up suggest that women benefit more from dating while men benefit more from hooking up. U.S students (150 women, 71 men) at a midsized southeastern university indicated preferences for dating and hooking up across a number of situations and indicated the perceived benefits and risks associated with each. As hypothesized, in most situations women more than men preferred dating and men more than women preferred hooking up. Both genders perceived similar benefits and risks to dating and hooking up; differences provided insight into the sexual motives of college women and men.  相似文献

Although evidence suggests that the dorsal striatum contributes to multiple learning and memory functions, there nevertheless remains considerable disagreement on the specific associative roles of different neuroanatomical subregions. We review evidence indicating that the dorsolateral striatum (DLS) is a substrate for stimulus–response habit formation – incremental strengthening of simple SR bonds – via input from sensorimotor neocortex while the dorsomedial striatum (DMS) contributes to behavioral flexibility – the cognitive control of behavior – via prefrontal and limbic circuits engaged in relational and spatial information processing. The parallel circuits through dorsal striatum interact with incentive/affective motivational processing in the ventral striatum and portions of the prefrontal cortex leading to overt responding under specific testing conditions. Converging evidence obtained through a detailed task analysis and neurobehavioral assessment is beginning to illuminate striatal subregional interactions and relations to the rest of the mammalian brain.  相似文献

One method for defining pathways through which children develop severe conduct problems is based on the presence or absence of callous-unemotional (CU) traits. This study investigated potential differences between nonreferred children (mean age = 12.36 years; SD = 1.73) with and without CU traits (n = 98). Children with conduct problems, irrespective of the presence of CU traits, tended to have significant problems in emotional and behavioral regulation. In contrast, CU traits, irespective of the presence of conduct problems, were associated with a lack of behavioral inhibition. Hostile attributional biases were associated with conduct problems but only in boys and in the absence of CU traits. These findings suggest that the processes underlying deficits in emotional and behavioral regulation in children with conduct problems may be different for children with CU traits.  相似文献

Sometimes people believe that a run of similar independent events will be broken (belief in thegambler’s fallacy) but, other times, that such a run will continue (belief in the hot hand). Both of these opposite inductions have been explained as being due to belief in a law of small numbers. We argue that one factor that distinguishes these phenomena is people’s beliefs about the randomness of the underlying process generating the events. We gave participants information about a streak of events but varied the scenarios in such a way that the mechanism generating the events should vary in how random the participants would judge it to be. A manipulation check confirmed our assumptions about the scenarios. We found that with less random scenarios, the participants were more likely to continue a streak.  相似文献
