Production of Stress Retraction by Left- and Right-Hemisphere-Damaged Patients

An acoustic-perceptual investigation of a phonological phenomenon in which stress is retracted in double-stressed words (e.g., thirTEEN vs THIRteen MEN) was undertaken to identify the locus of functional impairments in speech prosody. Subjects included left-hemisphere-damaged (LHD) and right-hemisphere-damaged (RHD) patients and nonneurological controls. They were instructed to read sentences containing double-stressed target words in the presence of a clause boundary or its absence. Whereas all three groups of subjects were capable of manipulating the acoustic parameters that signal a shift in stress, there were some differences between the performance of the patient groups and that of the normal controls. Further, stress production deficits were more severe in LHD aphasic patients than in RHD patients. LHD speakers exhibited deficits in the control of both temporal and F0 cues. Their F0 disturbance appears to be secondary to a primary deficit in temporal control at the phase or sentence level, as an increased number of continuation rises found for the LHD patients seemed to arise from lengthy pauses within sentences. Findings are highlighted to address the nature of breakdown in speech prosody and the competing views of prosodic lateralization.     

When Self-Interest Matters

The relative influence of self-interest and values on policy preferences was assessed experimentally in a national survey that posed questions about three contemporary political issues—Social Security reform, the home mortgage interest tax deduction, and health care benefits for domestic partners. For each issue, respondents were randomly assigned to one of three priming conditions that influenced the frame of reference for their policy evaluations. The results show that people are more likely to recognize their own self-interest, and to act upon it, when their stakes in the policy are clear or when they have been primed to think about the personal costs and benefits of the policy. This relationship is somewhat weakened but not eliminated when sociotropic considerations are primed. People with a smaller stake in an issue are less likely to behave on the basis of self-interest and more likely to be influenced by their values and symbolic predispositions, especially when exposed to information that cues sociotropic concerns, group identifications, or value orientations.     

Culture and perceptions of self—other similarity

In testing possible cultural effects of the use of the self as an habitual reference point to which others are compared, we expected that: (a) individualistic participants (i.e., those who give priority to personal goals) would rate self—other similarity higher when asked “How similar is X to you?” than when asked “How similar are you to X?”, whereas nondirectional similarity judgements (“How similar are these two people?”) would resemble the former directional comparison; (b) collectivistic participants (i.e., those who give priority to in‐group goals) would show a weaker or, possibly, reversed pattern, especially using in‐group comparison others. Neither hypothesis was upheld. However, the individualists perceived the in‐group to be relatively more similar to themselves as compared to the collectivists. This difference cannot be explained by response bias, status asymmetry, or role differentiation. We propose an explanation in terms of the differential relationship between self and other representations for people from collectivist versus individualist cultures.     

Evidence for the underestimation of implicit in-group favoritism among low-status groups

We question the evidence and the reasoning underlying recent research suggesting that members of low-status groups often fail to show in-group favoritism at the implicit level. Specifically, we argue the predominant measure revealing this pattern of group attitudes (the IAT) is influenced by extrapersonal associations, just the sort of information that would lead low-status groups to appear not to prefer their in-group. In the research reported here, respondents from low-status groups (African-Americans in Study 1 and homosexual males in Study 2) exhibited no in-group favoritism on the standard IAT, replicating previous research. However, reliable in-group favoritism by members of both groups was revealed on a personalized IAT [Olson, M. A., & Fazio, R. H. (2004). Reducing the influence of extrapersonal associations on the Implicit Association Test: Personalizing the IAT. Journal of Personality and Social Psychology, 86, 653-667] that reduces extrapersonal influences. We also rule out the possibility that differential error rates can account for the different patterns observed on the two versions of the IAT.     

Problem-solving training for family caregivers of women with disabilities: A randomized clinical trial

ObjectiveTo examine the effectiveness of an individualized problem-solving intervention provided to family caregivers of women living with severe disabilities.DesignFamily caregivers were randomly assigned to an education-only control group or a problem-solving training (PST) intervention group. Participants received monthly contacts for 1 year.ParticipantsFamily caregivers (64 women, 17 men) and their care recipients (81 women with various disabilities) consented to participate.Main outcome measuresCaregivers completed the Social Problem-Solving Inventory – Revised, the Center for Epidemiological Studies Depression scale, the Satisfaction with Life scale, and a measure of health complaints at baseline and in three additional assessments throughout the year.ResultsMultilevel modeling was used to conduct intent-to-treat analyses of change trajectories for each outcome variable. Caregivers who received PST reported a significant linear decrease in depression over time; no effects were observed for caregiver health or life satisfaction. Caregivers who received PST also displayed an increase in constructive problem-solving styles over the year.ConclusionsPST may benefit community-residing family caregivers of women with disabilities, and it may be effectively provided in home-based sessions that include face-to-face visits and telephone sessions.     

Evolutionary Psychology： How Psychological Mechanisms Shaped by Natural Selection for Ancestral Environments Produce Current Behaviours

The central purpose of this paper is to explain how Darwin′s theory of evolution by natural selection can be used in understanding current human behaviour. First, Darwin′s logic is briefly described. Development is an important issue when applying evolutionary theory to human behaviour. The notion of innate developmental organization of psychological mechanisms is introduced. The possible social and political outcomes produced when different levels of innate developmental organization are paired with differ...     

The survival and developmental outcome of extremely low birthweight infants

The purpose of this retrospective study is to compare the factors affecting the survival and developmental outcome of extremely low birthweight infants (ELBW; < 1,001 gms.). One hundred and forty of two hundred and twenty-three ELBW neonates (63%) from two Level III NICUs born between 1986 and 1988 survived until discharge. Lower birthweight, 5-minute Apgar ≤ 3, and no administration of surfactant were the best predictors of infant mortality as assessed via logistic regression (correct classification = 78%). The functioning of 34 of these infants was assessed at approximately 18 months of age with the Bayley Scales of Infant Development. Mean performance on the Mental Development Index (MDI) was 88.65 ± 21.75, with 35.3% and 20.6% of infants scoring, respectively, I (< 85) and 2 (< 70) standard deviations below the mean. Given survival, intraventricular hemorrhage (IVH, Grade III or IV) was the best predictor of MDI performance as assessed via stepwise multiple regression (adjusted R²=.23). Cerebral palsy affected one fifth of the sample and was also best predicted by IVH. Discussion focuses on the conceptual and practical implications of the finding that infant survival and infant developmental status were associated with different factors.
