Blake's Development of the Number Words “One,” “Two,” and “Three”

A mother tracked her preschooler's number word development daily from 18 to 49 months of age. Naturalistic observations were supplemented with observations during structured (Kumon) training and microgenetic testing. The boy's everyday use of “two” did not become highly reliable and selective for 10 months (at 28 months), emerged later than that of words representing less abstract concepts, and was used in a relatively abstract manner to describe various visible pairs of items. He quickly generalized “two” to partially visible collections and then those that were not visible. Highly reliable use of “one” and “two” appeared to develop simultaneously, before he started using a plural rule, and before he could put out two items upon request. Reliable and accurate use of number words in everyday situations, particularly child-initiated efforts, preceded such use in the contexts of the Kumon training and microgenetic testing, both of which involved adult-initiated tasks. Educational implications include underscoring differences among the first number words by contrasting, for instance, one with two, and pointing out non-examples of a number (“not two”) as well as a wide variety of examples, such as “two blocks, two hands, two socks, two airplanes.”     

Minority-Specific Determinants of Mental Well-Being Among Lesbian, Gay, and Bisexual Youth

This study discusses the impact of stress specific to being lesbian, gay, or bisexual (LGB)—measured by means of the concepts of stigma consciousness and internalized homonegativity—on the mental well-being of LGB youth. Also, the effects of positive and negative social support were considered within the model. The sample consisted of 743 LGBs less than 26 years old who were recruited during the online ZZZIP survey in Flanders, Belgium. Hierarchical regression shows that LGB-specific unsupportive social interactions have the greatest direct effect on mental well-being of LGB youth, followed respectively by stigma consciousness, internalized homonegativity, and confidant support.     

Positioning theory as a discursive approach to understanding same‐sex intimate violence

This study focuses on same‐sex intimate violence, recognizing that violence in gay and lesbian relationships is as severe and prevalent as in heterosexual relationships. Positioning theory as a relational approach is used as an alternative to the dominant individual and structural accounts. Intimate violence is seen as produced through the assignment of rights and duties or positioning in couples' conversations. Two gay and two lesbian couples were interviewed. A basic discursive pattern was found from 25 accounts of episodes involving physical violence. Violence ensued only after the initiator of violence had claimed innocence or blamelessness and attributed guilt or blame on the receiver of violence. The findings are discussed in relation to the discursive production of power and violence.     

The timing deficit hypothesis of dyslexia and its implications for Hebrew reading

Vast amounts of neuropsychological evidence have been collected in recent years in support of the hypothesis that developmental dyslexia is caused not only by phonological deficits, but also by timing deficits that affect all senses (e.g., Tallal, Miller, & Fitch, 1995; Stein & Walsh, 1997). In parallel, recent developments in the study of Hebrew reading place heavy emphasis on root awareness in the mental lexicon and early root extraction in the process of word identification (e.g., Frost, Forster, & Deutch, 1997). The present study creates a link between the timing hypothesis and the special demands of Hebrew reading. The performance of dyslexics and normally reading children is compared on tasks requiring visual extraction of trigrams that approximates extracting roots out of Hebrew words. Partial findings show that dyslexics take longer and make more errors while performing trigram extractions on all levels examined, and that sequentiality in the task affects dyslexics and skilled readers in different ways.     

Actigraph data are reliable, with functional reliability increasing with aggregation

Motion sensor devices such as actigraphs are increasingly used in studies that seek to obtain an objective assessment of activity level. They have many advantages, and are useful additions to research in fields such as sleep assessment, drug efficacy, behavior genetics, and obesity. However, questions still remain over the reliability of data collected using actigraphic assessment. We aimed to apply generalizability theory to actigraph data collected on a large, general-population sample in middle childhood, during 8 cognitive tasks across two body loci, and to examine reliability coefficients on actigraph data aggregated across different numbers of tasks and different numbers of attachment loci. Our analyses show that aggregation greatly increases actigraph data reliability, with reliability coefficients on data collected at one body locus during 1 task (.29) being much lower than that aggregated across data collected on two body loci and during 8 tasks (.66). Further increases in reliability coefficients by aggregating across four loci and 12 tasks were estimated to be modest in prospective analyses, indicating an optimum trade-off between data collection and reliability estimates. We also examined possible instrumental effects on actigraph data and found these to be nonsignificant, further supporting the reliability and validity of actigraph data as a method of activity level assessment.     

Beyond “Survivor”: How Childhood Sexual Abuse Informs the Identity of Adult Women at the End of the Therapeutic Process

A qualitative method was used to explore how adult women experienced their identity after extensive therapy to deal with childhood sexual abuse. Seven women shared their healing journeys and their perceptions of the role of the abuse in their current life and self‐perceptions. Phenomenological analysis of the interview data revealed 5 common themes related to participants' self‐definition and self‐acceptance, sense of visibility and connection to others, current worldview, and residual losses. These findings are discussed in terms of their implications for trauma counselors.     

Reducing Disparities in Cancer Screening and Prevention through Community‐Based Participatory Research Partnerships with Local Libraries: A Comprehensive Dynamic Trial

Reduction of cancer‐related disparities requires strategies that link medically underserved communities to preventive care. In this community‐based participatory research project, a public library system brought together stakeholders to plan and undertake programs to address cancer screening and risk behavior. This study was implemented over 48 months in 20 large urban neighborhoods, selected to reach diverse communities disconnected from care. In each neighborhood, Cancer Action Councils were organized to conduct a comprehensive dynamic trial, an iterative process of program planning, implementation and evaluation. This process was phased into neighborhoods in random, stepped‐wedge sequence. Population‐level outcomes included self‐reported screening adherence and smoking cessation, based on street intercept interviews. Event‐history regressions (n = 9374) demonstrated that adherence outcomes were associated with program implementation, as were mediators such as awareness of screening programs and cancer information seeking. Findings varied by ethnicity, and were strongest among respondents born outside the U.S. or least engaged in care. This intervention impacted health behavior in diverse, underserved and vulnerable neighborhoods. It has been sustained as a routine library system program for several years after conclusion of grant support. In sum, participatory research with the public library system offers a flexible, scalable approach to reduce cancer health disparities.     

The Cognitive Underpinnings of Continuous Identity: Higher Episodic Memory Recall and Lower Heuristic Usage Predicts Highest Levels of Self-Continuity

Continuous identity (CI) is a sense of persistent identity wherein the present self is seen as overlapping with the past and future selves. This study addressed the hypothesis that judgments of CI require successful retrieval of information by examining the relationship between varying levels of CI and two forms of memory recall. The pattern of findings indicated that high levels of cued memory recall combined with low levels of heuristic usage were associated with higher levels of CI, and this occurred for both past-to-present CI and present-to-future CI. We propose that to achieve high levels of CI, individuals need to access and analyze a fund of stored autobiographical information.     

Mind-operated devices: mental control of a computer using biofeedback.

This study investigated whether people could learn to control a computer using a biofeedback interface that integrated their galvanic skin response (GSR), heart rate, and temperature. Twenty participants played a computer game using the biofeedback device, both individually and in pairs. Results indicated that most people learned to control the game after a single training session. The GSR measure was the most sensitive means of control. Pairs of participants controlled the device more effectively than single individuals did.
