Four types of bilinguals solved simple addition problems that were auditorily presented in their preferred language, the language in which they first learned arithmetic, or in their nonpreferred language. Subjects responded in the language in which the problems were presented. Solution time averaged .227 sec faster in the preferred language and was an increasing linear function of the number of addition operations required. The intercepts of the preferred and nonpreferred language functions significantly differed, but the slopes did not. The preferred language advantage was attributed to faster encoding and/or response times in the preferred language. When bilinguals used only one of their languages in a given experimental session, encoding/response times in the two languages were equivalent and the preferred language advantage was eliminated. 相似文献

As a result of the dramatic increase in women's participation in the work force, more relationship therapists are seeing couples who are dissatisfied with how domestic labor is divided in their homes. Although, this issue may seem therapeutically straightforward, there are many aspects which make its renegotiation surprisingly problematic and complex. This article is an effort to delineate some of these issues such as engaging men in therapy, exploring emotional issues connected with housework, and the mechanism of gatekeeping. Also included is a therapeutic framework for addressing client concerns about domestic responsibilities. 相似文献

Perfusion of hippocampal slices with an inhibitor of nitric oxide (NO) synthase-blocked induction of long-term potentiation (LTP) produced by a one-train tetanus and significantly reduced LTP by a two-train tetanus, but only slightly reduced LTP by a four-train tetanus. Inhibitors of heme oxygenase, the synthetic enzyme for carbon monoxide (CO), significantly reduced LTP by either a two-train or four-train tetanus. These results suggest that NO and CO are both involved in LTP but may play somewhat different roles. One possibility is that NO serves a phasic, signaling role, whereas CO provides tonic, background stimulation. Another possibility is that NO and CO are phasically activated under somewhat different circumstances, perhaps involving different receptors and second messengers. Because NO is known to be activated by stimulation of NMDA receptors during tetanus, we investigated the possibility that CO might be activated by stimulation of metabotropic glutamate receptors (mGluRs). Consistent with this idea, long-lasting potentiation by the mGluR agonist tACPD was blocked by inhibitors of heme oxygenase but not NO synthase. Potentiation by tACPD was also blocked by inhibitors of soluble guanylyl cyclase (a target of both NO and CO) or cGMP-dependent protein kinase, and guanylyl cyclase was activated by tACPD in hippocampal slices. However, biochemical assays indicate that whereas heme oxygenase is constitutively active in hippocampus, it does not appear to be stimulated by either tetanus or tACPD. These results are most consistent with the possibility that constitutive (tonic) rather than stimulated (phasic) heme oxygenase activity is necessary for potentiation by tetanus or tACPD, and suggest that mGluR activation stimulates guanylyl cyclase phasically through some other pathway. 相似文献

Transcultural hospital pastoral care's subjects, the immigrant and the refugee, are described. Differences and similarities are noted. Three difficulties—culture shock, prejudice, and ethnocentrism—are followed by principles of transcultural hospital pastoral care, the significance of hospitalization, and a case history.The Rev.

The current study examined the persistence and phenotypic presentation of inattention/overactivity (I/O) into early adolescence,
in a sample of institution reared (IR) children adopted from Romania before the age of 43 months. Total sample comprised 144
IR and 21 non-IR Romanian adoptees, and a comparison group of 52 within-UK adoptees, assessed at ages 6 and 11 years. I/O
was rated using Rutter Scales completed by parents and teachers. I/O continued to be strongly associated with institutional
deprivation, with continuities between ages 6 and 11 outcomes. There were higher rates of deprivation-related I/O in boys
than girls, and I/O was strongly associated with conduct problems, disinhibited attachment and executive function but not
IQ more generally, independently of gender. Deprivation-related I/O shares many common features with ADHD, despite its different
etiology and putative developmental mechanisms. I/O is a persistent domain of impairment following early institutional deprivation
of 6 months or more, suggesting there may be a possible pathway to impairment through some form of neuro-developmental programming
during critical periods of early development. 相似文献

Theory of Mind (ToM) and Executive Function (EF) have been associated with autism and with attention-deficit hyperactivity
disorder (ADHD), and hence might play a role in similar syndromes found following profound early institutional deprivation.
In order to examine this possibility the current study included a group of 165 Romanian adoptees, of whom 144 were adopted
into the UK from deprived institutional settings before 43months of age, and a group of 52 within-UK adoptees, all adopted
before 6months of age. Both groups were assessed at 6 and 11years. The Strange Stories task was used to assess ToM and the
Stroop task was used to assess EF, both at age 11. The Romanian adoptees displayed deficits in both ToM and EF compared with
the within-UK adoptee group. The degree of deficit was greater for children who had experienced more than 6months of institutional
deprivation. Deficits in both domains (ToM and EF) were associated with each of the three apparently deprivation-specific
problems, namely quasi-autism, disinhibited attachment and inattention/overactivity. Statistical analyses indicated a mediating
role for both ToM and EF with respect to quasi-autism; possibly a partial mediating role for EF with respect to inattention/overactivity;
and probably no mediating role for either ToM or EF in the case of disinhibited attachment. In conclusion, there is evidence
for a possible mediating role for ToM and EF in the development of some apparently deprivation-specific difficulties in institution-reared
Romanian adoptees, but neither accounts for the overall pattern of deprivation-related difficulties. 相似文献

Researchers have documented the positive effects of classwide peer tutoring on academic performance, engagement, and other
social behaviors of students with and without disabilities. Commonly, in classwide peer tutoring, students are paired and
the class is divided in half. Points are awarded for tutoring behavior and academic responding during the tutoring session.
At the end of the session, the half of the class with the most points earns a reward. In the current study, a fifth-grade
teacher implemented classwide peer tutoring for multiplication facts. Instead of the traditional reinforcement system, a randomized
classwide interdependent group contingency was implemented. Applying a multiple-probe design across problem sets, students
demonstrated increased multiplication fact fluency across three problem sets. Discussion focuses on applied implications for
contingency management when implementing classwide peer tutoring programs. 相似文献
