A Failure to Obtain “Disinhibition”

The effects of removing the mothers from rat litters for an hour a day on days 3 to 9 (separation treatment) were evaluated against effects for litters where the mothers were removed and immediately replaced (disturbance) and undisturbed controls. There were no consistent differences between the groups in the open-field, but separated and disturbed litters were heavier than controls as adults and not different from one another. At weaning, separated litters were heavier and disturbed litters lighter than controls. The results are discussed in terms of the possible mechanisms underlying the effects of removing the mother, with emphasis on the comparison of mechanisms based on the specific absence of the mother from the litter with incidental disturbance effects or altered maternal responsiveness.     

The Reinforcing Effect of a Differentiating Stimulus

Twenty Sprague Dawley rats, aged 22 to 26 months were given subcutaneous injections of 4.5 mg/kg methylphenidate or distilled water. Twelve minutes after the single injection was given, rats began 90 trials of avoidance conditioning. Drug animals made significantly more correct responses than did the control animals. Results indicate that use of methylphenidate in aged rats improved avoidance learning.     

Interfering with remembering and knowing: effects of divided attention at retrieval

A Remember-Know paradigm was used to examine the cognitive resource requirements of recollection and familiarity memory processes at retrieval. Younger and older adults studied a list of words, and in a later auditory recognition test indicated whether each word was Remembered, Known, or New. Retrieval was performed under full or divided attention (DA) conditions, with either a digit task to numbers, or an animacy task to words, presented visually. Younger and older adults showed an increase in false Remember responses during both DA conditions, indicating a general effect of attention on illusory recollection. Both age groups also showed decreased accuracy in Know responses, but only during the word-based DA condition, indicating a material-specific effect on familiarity. Aging was associated with decreased accuracy in Remember, but not Know, responses, and with increased latency in distracting task responses under DA conditions. Results suggest that avoiding false recollective responses during retrieval requires attentional resources, whereas accurate familiarity responses require the reactivation of content-specific representations.     

Severity and cost of unsafe abortion complications treated in Nigerian hospitals

CONTEXT: Each year, thousands of Nigerian women have unintended pregnancies that end in illegal abortion. Many such procedures occur under unsafe conditions, contributing to maternal morbidity and mortality. METHODS: In a 2002-2003 survey of women and their providers in 33 hospitals in eight states across Nigeria, 2,093 patients were identified as being treated for complications of abortion or miscarriage or seeking an abortion. Women's abortion experiences and the health consequences and associated costs were examined through bivariate analysis. Multivariate analysis was used to examine the characteristics of women by type of pregnancy loss and to compare characteristics among three groups of women who had induced abortions in differing circumstances. RESULTS: Among women admitted for abortion-related reasons, 36% had attempted to end the pregnancy before coming to the hospital (including 24% with and 12% without serious complications), 33% obtained an induced abortion at the facility (not withstanding the country's restrictive law) without having made a prior abortion attempt and 32% were treated for complications from a miscarriage. Of women with serious complications, 24% had sepsis, 21% pelvic infection and 11% instrumental injury; 22% required blood transfusion and 10% needed abdominal surgery. The women in this group were poorer and later in gestation than those who sought abortions directly from hospitals. They paid more for treatment (about 13,900 naira) than those who went directly to the hospital for an abortion (3,800 naira) or those treated for miscarriage (5,100 naira). CONCLUSIONS: Policy and program interventions are needed to improve access to contraceptive services and postabortion care in order to reduce abortion-related morbidity and mortality.     

Ambulante psychotherapeutische Versorgung depressiver Patienten

Background

The effectiveness of psychotherapeutic interventions in treating depressive disorders has been shown in manifold ways. However, information is missing from the point of view of psychotherapists concerning diagnostic and therapeutic procedures, their experienced difficulties and barriers, their self-assessment of their competence in the handling of depressive patients and the satisfaction with the cooperation in routine care.

Method

A cross-sectional survey of cognitive-behavioral (n=61) and psychodynamic psychotherapists (n=78) was carried out.

Results

The concordance of clinical diagnoses with diagnoses using the formal ICD-10 criteria was very low. Both groups feel themselves specifically responsible for early detection and differential diagnosis. They neither differ with regard to the frequency of cooperation contacts to other service providers nor with regard to their satisfaction with them or the experienced barriers in the care for depressed patients.

Conclusion

A good psychotherapeutic care exists with options for improvement concerning diagnostic procedures and a stronger connection network.     

Test Difficulty and Stereotype Threat on the GRE General Test1

This study investigated (a) the ability to minimize or eliminate stereotype threat by reducing the difficulty of items administered via a computer‐adaptive version of the Graduate Record Examinations General Test; and (b) the generalizability of these findings for Black students as well as women, and for verbal as well as quantitative sections of the test. Standard and easier versions of the test, and measures of stereotype threat and possible symptoms or sequelae of stereotype threat were administered to students bound for graduate school or already there. Reducing test difficulty did not have any differential effects on test performance or on explicit indexes of stereotype threat for White and Black students, and for men and women, that were statistically and practically significant. However, such effects did occur for some symptoms or sequelae, mainly for White students and women.
