Rule learning transfer across linguistic and visual modalities in 7-month-old infants

Rule learning (RL) refers to infants’ ability to extract high-order, repetition-based rules from a sequence of elements and to generalize them to new items. RL has been demonstrated in both the auditory and the visual modality, but no studies have investigated infants’ transfer of learning across these two modalities, a process that is fundamental for the development of many complex cognitive skills. Using a visual habituation procedure within a cross-modal RL task, we tested 7-month-old infants’ transfer of learning both from speech to vision (auditory-visual—AV—condition) and from vision to speech (visual-auditory—VA—condition). Results showed a transfer of learning in the AV condition, but only for those infants who were able to efficiently extract the rule during the learning (habituation) phase. In contrast, in the VA condition infants provided no evidence of RL. Overall, this study indicates that 7-month-old infants can transfers high-order rules across modalities with an advantage for transferring from speech to vision, and that this ability is constrained by infants’ individual differences in the way they process the to-be-learned rules.     

Evidence From Marginally Significant t Statistics

ABSTRACT

This article examines the evidence contained in t statistics that are marginally significant in 5% tests. The bases for evaluating evidence are likelihood ratios and integrated likelihood ratios, computed under a variety of assumptions regarding the alternative hypotheses in null hypothesis significance tests. Likelihood ratios and integrated likelihood ratios provide a useful measure of the evidence in favor of competing hypotheses because they can be interpreted as representing the ratio of the probabilities that each hypothesis assigns to observed data. When they are either very large or very small, they suggest that one hypothesis is much better than the other in predicting observed data. If they are close to 1.0, then both hypotheses provide approximately equally valid explanations for observed data. I find that p-values that are close to 0.05 (i.e., that are “marginally significant”) correspond to integrated likelihood ratios that are bounded by approximately 7 in two-sided tests, and by approximately 4 in one-sided tests.

The modest magnitude of integrated likelihood ratios corresponding to p-values close to 0.05 clearly suggests that higher standards of evidence are needed to support claims of novel discoveries and new effects.     

Improved Methods for Estimating Flood Depth Exceedances Within Storm Surge Protection Systems

Contemporary studies conducted by the U.S. Army Corps of Engineers estimate probability distributions of flooding on the interior of ring levee systems by estimating surge exceedances at points along levee system boundaries, calculating overtopping volumes generated by this surface, then passing the resulting volumes of water through a drainage model to calculate interior flood depths. This approach may not accurately represent the exceedance probability of flood depths within the system interior; a storm producing 100‐year surge at one point is unlikely to simultaneously produce 100‐year surge levels everywhere around the system exterior. A conceptually preferred approach estimates surge and waves associated with a large set of storms. Each storm is run through the interior model separately, and the resulting flood depths are weighted by a parameterized likelihood of each synthetic storm. This results in an empirical distribution of flood depths accounting for geospatial variation in any individual storm's characteristics. This method can also better account for the probability of levee breaches or other system failures. The two methods can produce different estimates of flood depth exceedances and damage when applied to storm surge flooding in coastal Louisiana. Even differences in flood depth exceedances of less than 0.2 m can still produce large differences in projected damage. This article identifies and discusses differences in estimated flood depths and damage produced by each method within multiple Louisiana protection systems. The novel coupled dynamics approach represents a step toward enabling risk‐based design standards.     

The State of Sex Research in MFT and Family Studies Literature: A Seventeen‐Year Content Analysis

The ability to conceptualize and treat sexual problems has been widely accepted as a crucial skill to master the MFT training. However, clients’ sexual relationships are often ignored by clinicians because of a lack of experience or training, or personal discomfort. In this content analysis, we review sex and sex therapy research within MFT and family studies journals since the turn of the century. Of the 13,919 articles published within the 15 journals, 137 focused on sexuality or sex therapy. The articles were divided into five themes: sexual and relational health, sexual diversity, treatment and contributors of sexual dysfunction, sex therapy practices, and sexual education and development. Implications for clinical practices, sex therapy integration, and future research are discussed.     

The Impact of Blamer‐softening on Romantic Attachment in Emotionally Focused Couples Therapy

Emotionally Focused Couples Therapy (EFT; Johnson, 2004 ) treats relationship distress by targeting couples' relationship‐specific attachment insecurity. In this study, we used hierarchical linear modeling (Singer & Willett, 2003 ) to examine intercept and slope discontinuities in softened couples' trajectories of change in relationship satisfaction and relationship‐specific attachment over the course of therapy from a total sample of 32 couples. Softened couples (n = 16) reported a significant increase in relationship satisfaction and a significant decrease in attachment avoidance at the softening session. Although softened couples displayed an initial increase in relationship‐specific attachment anxiety at the softening session, their scores significantly decreased across post‐softening sessions. Results demonstrated the importance of the blamer‐softening change event in facilitating change in EFT.     

Trapped bodies,moving minds: Uncertainty and migration among marginalised urban youth in Ethiopia

This paper from YOUR World Research highlights and explores the role of positive uncertainty in lives, strategies and transitions towards adulthood of marginalised children and youth in two urban locations in Ethiopia. Young men and women embraced notions of positive uncertainty, making journeys to street situations and internationally in search of more hopeful futures. While youth navigate uncertainty positively in the short term, the research suggests this is temporal and their agency relational and embedded. They seek support from peers but still want to belong and be accepted by their families and communities.     

An Assessment of Social Work Education Efforts to Recruit and Retain MSW Students of Color

Social work programs in the United States (N=74) were investigated to determine strategies used for recruiting and retaining MSW students of color. Most schools had student populations exceeding 25,000 and combined BSW, MSW, and PhD programs. Data were collected using a Graduate Recruitment and Retention Scale with corresponding and acceptably stable subscales (alpha coefficients=.86 and .83, respectively). Long-term and durable problems were revealed vis-à-vis graduate student diversity, and few significant differences existed between public and private MSW program student diversity efforts. One exception was personalized follow-up to inquiries about application processes (p=0.01). Public or private status did not predict student diversity efforts in recruitment (Lambda [20, 35]=0.542, p>0.05, partial eta squared=0.458) or retention (Lambda [13, 50]=0.865, p>0.05, partial eta squared=0.135).

Trading sex: voluntary or coerced? The experiences of homeless youth

This study examined the circumstances surrounding a homeless youth's "decision" to trade sex for food, money, shelter, or drugs. Forty homeless youth in 4 Midwestern states participated in individual in-depth qualitative interviews. Interviewers recruited youth both through service agencies and through street outreach. The findings revealed that approximately 1/3 of the sample had some experience with trading sex, whether it was in the form of having traded sex, having been propositioned to trade sex but having refused, or having friends or acquaintances that had traded sex. Young people's reports indicated that they had traded sex for things they deemed necessary in order to survive (i.e., food, shelter, money, or drugs), and that they did not want to trade sex, but did so because they were desperate and lacked alternatives. Additionally, others were coerced, manipulated, or forced to do so; thus indicating that the decision to trade sex is not always voluntary. We discuss the implications of these findings in terms of cumulative effects on youths' later development. Directions for future research among this population are also discussed.
