Immigrant adolescents behaving as culture brokers: a study of families from the former Soviet Union

In immigrant families, culture brokering (CB) occurs when children mediate the new culture for their family. The authors examined CB in Russian immigrant adolescent-mother dyads (N=226) to determine the types and amounts of CB that Russian adolescents performed, why adolescents assumed the CB role, and how the role affected adolescent and familial functioning. The present results indicated that most adolescents reported CB for their families (89%). Children of families that more recently arrived in the U.S., with mothers who were less American-language acculturated, culture brokered more. Higher levels of CB related to (a) higher adolescent stress and reports of problems at home and with friends and (b) lower feelings of school membership. Parent-reported problems at home did not relate to CB. The authors discussed implications for future research on the role of the child as culture broker.     

Attentional and perceptual sources of the auditory attentional blink

When a rapid succession of auditory stimuli is listened to, processing of the second of two successive targets among fillers is often impaired, a phenomenon known as the attentional blink (AB). Three experiments were conducted to examine the role of filler items in modulating the size of the auditory AB, using a two-alternative forced choice discrimination paradigm. In the first experiment, dual-stream presentations in which low- and high-pitch items were separated by six semitones were tested. A transient deficit in reporting the probe was observed in the presence of fillers that was greater when fillers were in the same stream as the probe. In the absence of a filler, there was a residual deficit, but this was not related to the time lag between the target and the probe. In the second and third experiments, in which single-stream presentations were used, a typical AB was found in the presence of homogeneous fillers, but heterogeneous fillers tended to produce a greater deficit. In the absence of a filler, there was little or no evidence of a blink. The pattern of results suggests that other attentional and perceptual factors contribute to the blink.     

Family Support and Mental Health in Pregnant Women Experiencing Interpersonal Partner Violence: An Analysis of Ethnic Differences

This study investigated the relationship between family support and mental health in a community sample of pregnant women experiencing interpersonal partner violence (IPV). This study also examined how family support may differentially affect mental health in Black and White women experiencing IPV. A total of 110 participants (32 Black and 78 White) were obtained from the first time period of a longitudinal study examining the effects of domestic violence on women. The model was supported (χ² = 142.55; df = 72, p > .001, RMSEA = .07). Black women had better mental health than White women. However, ethnicity was not a significant predictor of family support. Implications from this study highlight the need for further research on the role of family support in the lives of physically abused women as well as the need to incorporate cross cultural perspectives when examining this issue.     

Improved picture naming in chronic aphasia after TMS to part of right Broca's area: an open-protocol study

Functional imaging studies with nonfluent aphasia patients have observed "over-activation" in right (R) language homologues. This may represent a maladaptive strategy; suppression may result in language improvement. We applied slow, 1 Hz repetitive transcranial magnetic stimulation (rTMS) to an anterior portion of R Broca's homologue daily, for 10 days in four aphasia patients who were 5-11 years poststroke. Significant improvement was observed in picture naming at 2 months post-rTMS, with lasting benefit at 8 months in three patients. This preliminary, open trial suggests that rTMS may provide a novel treatment approach for aphasia by possibly modulating the distributed, bi-hemispheric language network.     

Auditory attentional capture during serial recall: violations at encoding of an algorithm-based neural model?

A novel attentional capture effect is reported in which visual-verbal serial recall was disrupted if a single deviation in the interstimulus interval occurred within otherwise regularly presented task-irrelevant spoken items. The degree of disruption was the same whether the temporal deviant was embedded in a sequence made up of a repeating item or a sequence of changing items. Moreover, the effect was evident during the presentation of the to-be-remembered sequence but not during rehearsal just prior to recall, suggesting that the encoding of sequences is particularly susceptible. The results suggest that attentional capture is due to a violation of an algorithm rather than an aggregate-based neural model and further undermine an attentional capture-based account of the classical changing-state irrelevant sound effect.     

The effects of focal and global attentional systems on spatial biases

The background page on which a stimulus is presented can influence the allocation of attention to that stimulus. The purpose of this study was to learn if there are hemispheric asymmetries in how background distraction affects attentional processing. Asymmetries were investigated by having right eye dominant subjects perform line bisections and manipulating the side of background distraction (right versus left), the eye of regard (right versus left), and the type of attention allocated (focal versus global). Overall subjects bisected lines to the left of center (pseudoneglect) and when viewing with the right eye (versus left) deviated more to the left. Subjects had more background distraction when viewing symbol than solid lines. Although overall, bias did not differ with the side of background distraction or the line being on one side or the other, when subjects viewed symbol, but not solid lines, this leftward bias was increased when the line was displaced to the right, thereby increasing the size of the left sided background. These findings suggest that when engaging the left hemisphere by using focused attention and placing the line on the right side, there is more distraction than when the right hemisphere is engaged.     

Validation of the Beck Depression Inventory-II in a low-income African American sample of medical outpatients

The psychometric properties of the Beck Depression Inventory-II (BDI-II) are well established with primarily Caucasian samples. However, little is known about its reliability and validity with minority groups. This study evaluated the psychometric properties of the BDI-II in a sample of low-income African American medical outpatients (N=220). Reliability was demonstrated with high internal consistency (.90) and good item-total intercorrelations. Criterion-related validity was demonstrated. A confirmatory factor analysis supported a hierarchical factor structure in which the BDI-II reflected 2 first-order factors (Cognitive and Somatic) that in turn reflected a second-order factor (Depression). These results are consistent with previous findings and thus support the use of the BDI-II in assessing depressive symptoms for African American patients in a medical setting.     

Disruption by speech of serial short-term memory: The role of changing-state vowels

Serial short-term memory is markedly impaired by the presence of irrelevant speech so long as the successive tokens within the irrelevant speech are phonologically (or acoustically) dissimilar (Jones & Macken, 1995b). In two experiments in which consonant—vowel—consonant syllables were used as irrelevant speech tokens, we sought to evaluate the relative disruptive potency of changes in the final consonant only (Experiment 1), in the initial consonant, or in the vowel portion (Experiment 2) of each token. The results suggest that the vowel changes are the dominant source of disruption. This dominance may be explained, at least in part, by the role played by vowel sounds in the perceptual organization of speech and, in turn, the particular propensity for vowel changes to yield information about serial order. The results are consistent also with the view that the factors that promote order encoding in sound are also the ones that promote disruption.
