The Use of Pitch Accent in Word–Object Association by Monolingual Japanese Infants

This study investigated the lexical use of Japanese pitch accent in Japanese‐learning infants. A word–object association task revealed that 18‐month‐old infants succeeded in learning the associations between two nonsense objects paired with two nonsense words minimally distinguished by pitch pattern (Experiment 1). In contrast, 14‐month‐old infants failed (Experiment 2). Eighteen‐month‐old infants succeeded even for sounds that contained only the prosodic information (Experiment 3). However, a subsequent experiment revealed that 14‐month‐old infants succeeded in an easier single word–object task using pitch contrast (Experiment 4). These findings indicate that pitch pattern information is robustly available to 18‐month‐old Japanese monolingual infants in a minimal pair word‐learning situation, but only partially accessible in the same context for 14‐month‐old infants.     

Childhood Victimization,Cognitive Schemas,and Unwanted Consensual Sex Among College Students

Objective: Unwanted consensual sex (UCS)—freely consenting to sex that is neither wanted nor desired—is largely excluded from campus programming and the literature on sexual behavior. The present study expands on previous research to examine the relation between childhood victimization experiences and UCS.

Methods: Data were gathered using an online survey of college students.

Results: In the past year, 43% percent of 587 college students who engaged in sexual activity also engaged in UCS at least once. Childhood victimization was modestly related to frequency of UCS. The relation between childhood victimization and UCS was mediated by disconnection/rejection schemas (e.g., beliefs that one’s needs will not be met by others).

Conclusions: Results suggest that altering cognitive schemas through evidence-based psychotherapy may interrupt the relation between childhood victimization and engagement in UCS.     

Explicit Verbal Sexual Consent Communication: Effects of Gender,Relationship Status,and Type of Sexual Behavior

Objectives: College students believe that they are supposed to be explicit and verbal in their sexual consent communication. We examined various contexts to determine when sexual consent is likely to be communicated explicitly and verbally. Method: We surveyed U.S. college students’ (n?=?707) sexual consent communication. Results: We identified contexts when explicit verbal consent cues are less likely—when the person is a woman, when the sexual relationship is casual, and when the sexual behavior is not vaginal-penile intercourse. Conclusions: If sexual consent is contextual, that means communicating consent should not ever be taken for granted.     

Social Effects of Movement Synchrony: Increased Infant Helpfulness only Transfers to Affiliates of Synchronously Moving Partners

Interpersonal synchrony increases cooperation among adults, children, and infants. We tested whether increased infant helpfulness transfers to individuals uninvolved in the movement, but shown to be affiliates of a synchronously moving partner. Initially, 14‐month‐old infants (N = 48) watched a live skit by Experimenters 1 and 2 that either demonstrated affiliation or individuality. Infants in both groups were then randomly assigned to be bounced to music either synchronously or asynchronously with Experimenter 1. Infant instrumental helpfulness toward Experimenter 2 was then measured. If the two experimenters were affiliates, infants from the synchronous movement condition were significantly more helpful toward Experimenter 2 than infants from the asynchronous movement condition. However, if the two experimenters were not affiliated, synchrony effects on prosociality did not transfer to Experimenter 2. These results show the importance of musical synchrony for social interaction and suggest that infants may use an understanding of third‐party social relationships when directing their own social behaviors.     

The reporting of grief by one newspaper of record for the U.S.: the New York Times

One source people can rely on for clues on how to grieve a loss is through accounts of such experiences reported in the mass media. This research examines how grief has been reported at one newspaper of record for the U.S.: The New York Times. Using theories of social construction and the sick role, this exploratory study attempts to observe whether grieving is portrayed by media as a social problem, particularly as a health or medical issue which can be treated and cured, and also discusses those who are not identified in the mourner role in newspaper reports.     

Analysis of ordinal outcomes with longitudinal covariates subject to missingness

We propose a mixture model for data with an ordinal outcome and a longitudinal covariate that is subject to missingness. Data from a tailored telephone delivered, smoking cessation intervention for construction laborers are used to illustrate the method, which considers as an outcome a categorical measure of smoking cessation, and evaluates the effectiveness of the motivational telephone interviews on this outcome. We propose two model structures for the longitudinal covariate, for the case when the missing data are missing at random, and when the missing data mechanism is non-ignorable. A generalized EM algorithm is used to obtain maximum likelihood estimates.     

The Criteria for Open Access

Abstract

Each proposal for Open Access (OA) has its unique combination of features; each argument for or against OA focuses on particular features or criteria. This article is intended to discuss these criteria, both individually and also as each of them contributes to the different proposals for OA. Evaluation of the proposals themselves is not attempted. This discussion is intended to be of value to the supporters of OA, in choosing which plan to adopt, and to those opposed to OA, in showing where the weaknesses do and do not lie. In other words, this article intends to improve the level of factual understanding in the ongoing discussions.     

Suicide prevention and community-level indictors

This study sought to develop a set of easily obtainable, relevant measures of a community's condition that could be used to guide its suicide prevention efforts. Existing data were gathered across 159 Georgia counties for nine potential social indicators (rates of net migration, divorce, unemployment, violent crimes reported, driving under the influence of alcohol or drugs [DUI] crashes, high school dropouts, Temporary Assistance for Needy Families [TANF], percentage of population aged 65 or older, and percentage of population who are white males) that had been chosen by the communities. Data on the social indicators from 1995 through 1999 were averaged and analyzed to determine their correlation with aggregated 5-year county suicide rates. Results of multivariate modeling procedures showed number of DUI crashes and percentage of the population aged 65 or older to be significant correlates of the suicide rate, controlling for other potential indicators. These preliminary data may provide a useful model of a county's 5-year suicide rate among counties reporting 20 or more suicides. Research with additional indicators and in other states will help determine the generalizability of these findings to other communities.     

Fighting spam with statistics

Spam—unsolicited commercial e-mail—is a complex and growing problem, and threatens to derail the internet revolution. Joshua Goodman and David Heckerman of Microsoft Research describe some statistics-based methods for blocking spam, first by distinguishing it from wanted mail, and then by constructing puzzles they propose to use to challenge suspected spammers.
