Shape, color and the other-race effect in the infant brain

The 'other-race' effect describes the phenomenon in which faces are difficult to distinguish from one another if they belong to an ethnic or racial group to which the observer has had little exposure. Adult observers typically display multiple forms of recognition error for other-race faces, and infants exhibit behavioral evidence of a developing other-race effect at about 9 months of age. The neural correlates of the adult other-race effect have been identified using ERPs and fMRI, but the effects of racial category on infants' neural response to face stimuli have to date not been described. We examine two distinct components of the infant ERP response to human faces and demonstrate through the use of computer-generated 'hybrid' faces that the observed other-race effect is not the result of low-level sensitivity to 3D shape and color differences between the stimuli. Rather, differential processing depends critically on the joint encoding of race-specific features.     

Predicting women's and men's reactions to geographic separation: relational interdependence matters

Participant sex and a theorized correlate of biological sex, relational interdependence, were tested as relative predictors of the extent to which daters 1) missed and 2) used emotional support to cope when geographically separated from their dating partners. One hundred twenty-four daters completed multiple measures of missing and coping during their colleges' winter breaks. Results from regression analyses indicated that levels of missing and seeking emotional support differed as a function of biological sex. Further, relational interdependence was reliably associated with missing and seeking emotional support in theoretically consistent ways. Mediation analyses highlighted the importance of considering relational interdependence or other individual differences that covary with biological sex when studying close relationship phenomena.     

Compatibilism and the Notion of Rendering Something False

In my paper I am concerned with Peter van Inwagen's Consequence Argument. I focus on its probably best known version. In this form it crucially employs the notion of rendering a proposition false, anotion that has never been made sufficiently clear. The main aim of my paper is to shed light on thisnotion. The explications offered so far in thedebate all are based on modal concepts. Iargue that for sufficient results a ``stronger',hyper-intensional concept is needed, namely theconcept expressed by the word ``because'. I show that my analysis is superior to the prior ones. On the basis of this analysis I further explain why van Inwagen's argument fails.     

Process generalization and the prediction of performance on mental imagery tasks

Kosslyn (1980, 1983) theorized that performance measures on imagery tasks may vary as a function of the existence of independent processes in imaging ability. The present study determined whether improvement can be made in performance on such tasks with practice. It also considered whether performance on such tasks improves with practice and whether this improvement generalizes. Experiment 1 determined whether improvement in a mental rotation task generalizes to improvement in a geometric analogies task, with both tasks weighted in Kosslyn's find process, but not in a line drawing memory task weighted in Kosslyn's regenerate process. In Experiment 2, we examined generalization in improvement from a geometric analogies task to a mental rotation task. In Experiment 3, we tested whether improvement in an animal imagery task (Kosslyn, 1975) generalizes to improvement in a line drawing memory task, with both tasks weighted in Kosslyn's regenerate process, but not to improvement in a mental rotation task. Performance improved with practice on all tasks. Furthermore, performance improved from one task to another only if both tasks loaded on the same process.     

Danger and usefulness are detected early in auditory lexical processing: evidence from electroencephalography

Visual emotionally charged stimuli have been shown to elicit early electrophysiological responses (e.g., [Ihssen et al., 2007], [Schupp et al., 2003] and [Stolarova et al., 2006]). We presented isolated words to listeners, and observed, using generalized additive modeling, oscillations in the upper part of the delta range, the theta range (Bastiaansen & Hagoort, 2003), and the lower part of the alpha range related to degree of (rated) danger and usefulness (Wurm, 2007) starting around 150 ms and continuing to 350 ms post stimulus onset. A negative deflection in the oscillations tied to danger around 250-300 ms fits well with a similar negativity observed in the same time interval for visual emotion processing. Frequency and competitor effects emerged or reached maximal amplitude later, around or following the uniqueness point. The early effect of danger, long before the words’ uniqueness points, is interpreted as evidence for the dual pathway theory of LeDoux (1996).     

The costs of racism for marriage: how racial discrimination hurts, and ethnic identity protects, newlywed marriages among Latinos

The experience of racial or ethnic discrimination is a salient and severe stressor that has been linked to numerous disparities in important outcomes. Yet, the link between perceived discrimination and marital outcomes has been overlooked by research on relationship stressors. The current study examined this link and tested whether ethnic identity buffered the relation between discrimination and ratings of marital quality and verbal aggression. A sample of 330 Latino newlyweds completed measures of perceived discrimination, ethnic identity, spouse's verbal aggression, and marital quality. Each spouse's interviewer also independently rated marital quality. Dyadic analyses revealed that husbands' experience of discrimination negatively predicted wives' marital quality, but only for husbands with weak ethnic identity. Wives whose husbands had strong ethnic identity were buffered from this effect. Identity also buffered the relation between husbands' discrimination and verbal aggression toward their wives, and this effect mediated the association between discrimination, identity, and marital quality.     

Hispanic Infants with Cystic Fibrosis Show Low CFTR Mutation Detection Rates in the Illinois Newborn Screening Program

States develop specific protocols for cystic fibrosis (CF) newborn screening to reflect the population served. We hypothesized that mutation distribution and detection rates would differ between Hispanic and non-Hispanic CF patients diagnosed by IL newborn screen with more Hispanic infants carrying mutations not detected by the state panel. Data from CF cases diagnosed via newborn screen in IL between 3/1/2008 and 10/31/2010 were reviewed. More Hispanic infants with CF had one or more undefined mutations after screening, in comparison to non-Hispanic Caucasian patients (40% vs. 9.5%; p?相似文献   

A Developmental Meta-Analysis of Peer Conflict Resolution

A series of meta-analyses examine developmental trends in peer conflict resolution. Peer conflict resolutions are most likely to involve negotiation, with coercion and then disengagement the next most likely strategies. Patterns of conflict resolution differ with age. Coercion is common among children and disengagement is rare. Negotiation is prevalent among adolescents and young adults; the former do not differ in terms of coercion and disengagement, whereas the latter tend to avoid coercion in favor of disengagement. Conflict resolutions also vary as a function of peer relationships, assessment procedures, and reporters. Negotiation prevails in all peer relationships except those with siblings; there is more negotiation among romantic partners than among friends, and more negotiation among friends than among acquaintances. Negotiation is the overwhelming strategy of choice for those presented with hypothetical disputes, but actual conflicts tend to be resolved by coercion. Observers indicate that most conflicts involve coercive resolutions, in contrast to self-reports, which suggest that negotiation prevails. Although conclusions are qualified by the limited number of studies available, follow-up moderator analyses indicate that negotiation increases and coercion declines with age across most peer relationships, assessment procedures, and reporters such that different patterns of conflict resolution during childhood give way to the same relative ordering of strategies during young adulthood.     

Twelve-Year Review of Major Family Therapy Journals: Topic Areas,Authors' Characteristics and Publishing Institutions

Topics of interest, authors' characteristics, and institutions in three major MFT journals (American Journal of Family Therapy, Family Process, and Journal of Marriage and Family Therapy) from 1992 to 2004 were reviewed. The findings indicated that most authors had earned a Ph.D. and worked in a university setting as a faculty member. Publishing institutions were equally distributed throughout the United States. Six topics areas accounted for 42% of articles written including (1) Theory; (2) Techniques and Interventions; (3) Assessments and Instruments; (4) Ethnic, Minority, and Cross-cultural Issues; (5) Violence, Abuse, and Incest; and (6) Training and Supervision. As in the earlier reviews, faculty and/or students from Purdue University and Brigham Young University authored the highest percentage of papers.
