In three studies, we examined the role task rules play in multitasking performance. We postulated that rules should be especially important for individuals highly motivated to have structure and clear answers, i.e., those high on need for cognitive closure (NFC). High NFC should thus be related to greater compliance with task rules. Specifically, given high goal importance, NFC should be more strongly related to a multitasking strategy when multitasking is imposed by the rules, and to a mono-tasking strategy when monotasking is imposed by the rules. This should translate into better multitasking or mono-tasking performance, depending on condition. Overall, the results were supportive as NFC was related to a more mono-tasking strategy in the mono-tasking condition (Studies 1 and 2 only) and more dual-tasking strategy in the dual-tasking condition (Studies 1–3). This translated into respective differences in performance. The effects were significant only when goal importance was high (Study 1) and held when cognitive ability was controlled for (Study 2).  相似文献

Enormous gaps between HIV burden and health care availability in low-income countries raise severe ethical problems. This article analyzes four HIV-priority dilemmas with interest across contexts and health systems. We explore principled distributive conflicts and use the Atkinson index to make explicit trade-offs between health maximization and equality in health. We find that societies need a relatively low aversion to inequality to favor treatment for children, even with large weights assigned to extending the lives of adults: higher inequality aversion is needed to share resources equally between high-cost and low-cost treatment; higher inequality aversion is needed to favor treatment rather than prevention, and the highest inequality aversion is needed to favor sharing treatment between urban and rural regions rather than urban provision of treatment. This type of ethical sensitivity analysis may clarify the ethics of health policy choice.  相似文献

Two representative samples of adult Norwegians (n=2000) were asked a set of general and specific questions regarding their beliefs and opinions about human memory. The results indicate that on many questions, such as time of the earliest memories, inhibiting effects of collaboration, and memory for dramatic versus ordinary events, the views of the general public concurred with current research findings, and people in general had realistic views about their own memory performance. On other questions, such as the reliability of olfactory as compared with visual and auditory memory, the memory of small children in comparison with that of adults, the likelihood of repression of adult traumatic memories, and on more general questions such as the possibility of training memory and the capacity limitations of long-term memory, a large proportion of the participants expressed views that are less supported by scientific evidence. Implications of these findings are briefly discussed.  相似文献

Clark and Beck (1999) and Williams et al. (1997) have come up with quite different conclusions regarding which cognitive processes are most affected by negative self-schemata and negative knowledge structures. In order to increase the understanding of differences in effortful and automatic processing in depression, we compared never depressed (ND), previously depressed (PD) and clinically depressed (CD) individuals on free recall, recognition and fabrication of positive and negative self-statements. The results showed that: (i) overall NDs and PDs recalled more positive self-statements than CDs, whereas CDs correctly recognized more negative self-statements than NDs and PDs; and (ii) CDs and PDs fabricated more negative than positive self-statements, whereas no difference was obtained for NDs. The results seem to be in line with Clark and Beck's suggestions. However, there are several aspects of the present findings that make the picture more complicated.  相似文献

The prevalence of older adolescents' positive attitudes toward younger sexual partners was investigated through three measures of self-reported hypothetical likelihood of having sex with preadolescents and younger adolescents (LSA), using a school-based cluster sample of 710 Norwegian 18- to 19-year-olds attending nonvocational high schools in Oslo. Some likelihood of having sex with a preadolescent (less than 12 years of age) was reported by 5.9% of the males. The 19.1% of the males who indicated some likelihood of having sex with a 13- to 14-year old, compared to those who did not, reported more high-frequency drinking, more alcohol-related problems, earlier sexual initiation, more conduct problems, and poorer psychosocial adjustment. This subgroup also reported more high-frequency use of pornography, having more friends with an interest in child pornography and violent pornography, and greater use of coercion to obtain sexual favors.  相似文献

Several studies indicate that mental health and mental health service vary with ethnicity. Ethnically linked social differences affect these results. We examined the multiethnic population in northern Norway where social inequalities between the Sami and the non-Sami population are not prominent. Clients (N=347) and therapists (N=32) in outpatient treatments reported demographics, ethnicity and the therapeutic alliance. Clients also reported pretreatment psychosocial status, service utilization and the type of help requested. Therapist recorded clinical and diagnostic assessments and treatment plans. The Sami and non-Sami client groups were similar in demographics and pretreatment psychosocial characteristics. However, the therapists prescribed more sessions and more socially focused interventions when clients were Sami. Verbal therapy was more often used by the non-Sami therapists. Alliance ratings were positively correlated only between Sami therapists and their clients, and Sami therapists rated the largest initial clinical improvement. Clinics located in the high Sami density areas offered their clients more therapy sessions, than in clinics in the high non-Sami density areas. Ethnic similarity between client and therapist were associated with more frequent use of medication and less frequent use of verbal therapy.  相似文献

The HKB model for rhythmic interlimb coordination has highlighted the importance of coordinative stability and loss of stability, and introduced, with this focus, a new set of explanatory constructs. However, the phenomenological character of both parts of this model (i.e., the potential and the associated system of coupled oscillators) precludes an understanding of how the observed stability characteristics are related to more specific (e.g., biomechanical and neurophysiological) aspects of the movement system. A two-tiered model (involving a distinction between 'neural' and 'effector' dynamics) is discussed that offers handles for addressing such underpinnings of the identified coordination dynamics. The promise of the model in this regard is illustrated by two recent studies showing how explicit accounts of the effector dynamics may help disclose why (and how) particular properties of the peripheral system affect the overall coordination dynamics.  相似文献

This study examined whether sufficient-response-exemplar training of vocal imitation would result in improved articulation in children with phonological disorder, and whether improved articulation established in the context of vocal imitation would transfer to other verbal classes such as object naming and conversational speech. Participant 1 was 6 years old and attended first grade in a regular public school. Participant 2 was 5 years 4 months old and attended a public kindergarten. Both participants had normal hearing and no additional handicaps. A multiple baseline design across behaviors (target sounds or blends) was employed to examine whether the vocal imitation training resulted in improved articulation. Results showed that both participants improved articulation once training was implemented, and that the improved articulation transferred from vocal imitation to more natural speech such as object naming and conversational speech. Improvement established during training was maintained posttraining and at a 6-month follow-up.  相似文献

Young and old subjects were investigated to examine whether: the effects of priming are influenced by aging; there is independence between primed word-fragment completion and recognition performances; and the dependence between different tests is influenced by aging. A successive test paradigm was employed involving repeated assessment of to-be-remembered words by means of recognition and primed word-fragment completion. The results show that implicit memory declines with increasing age, and that correlations between different memory tests decrease with age. The outcome suggests that age-related memory decline involves several forms of memory, including primed word-fragment completion, and is reflected in correlations between measures of implicit and explicit memory.  相似文献
