Dissipation of retroactive interference in human infants

In 3 experiments with 85 human 3-month-olds, the authors asked whether retroactive interference with their memory of the original training stimulus is temporary or permanent. Infants learned to move a mobile by kicking and then were exposed to a different mobile (Experiment 1) or context (Experiment 2) immediately or 3 days afterward (Experiment 3). They were tested after increasing delays with the original stimulus, the exposed stimulus, or a completely novel stimulus. Retroactive interference was temporary and unrelated to the exposure delay. The data are consistent with a retrieval-based account of interference. Memory updating (i.e., responding to the interfering stimulus) was coincident with retroactive interference, suggesting that retroactive interference is an adaptive mechanism that facilitates memory updating within a narrow time window.     

Ontogeny of early event memory: II. Encoding and retrieval by 2- and 3-month-olds

The ability of 2-month-old infants to discriminate changes in a 5-object crib mobile following a retention interval of 24 hr was assessed using the mobile conjugate reinforcement paradigm. Infants were trained in 3 daily 15-min sessions to produce mobile movement by footkicking. Twenty-four hr later, independent groups received generalization tests with mobiles containing 1–5 novel objects substituted into their original training mobile. A control group was tested with the original training mobile. These findings were compared with findings of 2 previous studies involving identical procedures with 3-month-olds, reanalyzed for measures of individual performance over successive test minutes. Although, in absolute terms, 2-month-olds had a flat generalization gradient relative to 3-month-olds, when each infant's kick rate during the generalization test was expressed relative to that infant's kick rate before, and at the end of, training, it was found that the generalization gradients of 2- and 3-month-olds were indistinguishable. The relative response measures indicated a surprising degree of specificity by both age groups: Test mobiles containing more than 1 novel object did not cue retrieval, but test mobiles containing no more than 1 new object yielded perfect retention and complete generalization. These data indicate that infants as young as 2 months are capable of encoding and maintaining a representation of the specific details of their training context for at least 24 hr and, after that delay, can perform fine discriminations based on the discrepancy between their test context and that representation.     

To Hook Up or Date: Which Gender Benefits?

Hooking up on college campuses has become more frequent than dating in heterosexual sexual interaction. Analysis of the relative benefits and costs associated with dating and hooking up suggest that women benefit more from dating while men benefit more from hooking up. U.S students (150 women, 71 men) at a midsized southeastern university indicated preferences for dating and hooking up across a number of situations and indicated the perceived benefits and risks associated with each. As hypothesized, in most situations women more than men preferred dating and men more than women preferred hooking up. Both genders perceived similar benefits and risks to dating and hooking up; differences provided insight into the sexual motives of college women and men.     

Halo Effects in Ratings of ADHD and ODD: Identification of Susceptible Symptoms

Halo effects in the assessment of ADHD and ODD were examined. Participants were 159 undergraduate college students who rated children described as showing disruptive behaviors. Bidirectional halo effects were found. Specifically, the presence of oppositionality artificially inflated ratings of inattention and hyperactivity, and the combined presence of inattention and hyperactivity artificially inflated ratings of oppositionality. Several specific items were found to be particularly susceptible to halo effects. Due to these halo effects caution should be exercised when diagnosing multiple behavior disorders, especially with items found to be particularly susceptible. Clinical interviews conducted by mental health professionals may help distinguish between the true presence of multiple disorders and halo effects based on ratings. Future research should determine whether structured interviews conducted by mental health professionals are less susceptible to halo effects than rating scales.     

Moving into tummy time,together: Touch and transitions aid parent confidence and infant development

“Back to sleep” messages can reduce prone practice for infants, with potential for motor delay and cranial deformation. Despite recommendations for “tummy time,” young infants fuss in prone, and parents report uncertainty about how to help infants tolerate prone positioning. We hypothesized that a Child'Space Method lesson, teaching proprioceptive touch and transitions to prone, would facilitate prone tolerance, parent behavioral support, and parent self-efficacy. This randomized study recruited parents (N = 37) of 2- to 5-month-old infants. On two visits, parents answered questions about infant behavior and parent experience, and played with their infant. Lesson group parents had the lesson following the first free play. One week later, lesson parents reported that infants tolerated more prone time and that parents showed more supportive behaviors in bringing infant to prone, as compared to waiting parents. Lesson parents’ efficacy, and infant behavior during play, trended in the hypothesized direction. The study demonstrated how a lesson in preparatory touch, and gradual transitions, promoted infant prone tolerance and also parent support of rolling, side-lying, and prone positioning. The lesson could be incorporated in parent education and early pediatric visits, helping infants and parents negotiate the prone challenge and setting the stage for further parent support of infant development.     

Victim Blaming in Young, Middle-Aged, and Older Adults: Variations on the Severity Effect

It has been long known that people blame victims for the bad things that happen to them, and that people blame victims more when the victims experience severe difficulties than when they experience minor difficulties, even if the victims were not particularly irresponsible. Little previous research has examined victim blaming in middle-age and older adults. One hundred and forty-five adults in 3 age groups (18–34, 35–59, and 60–84) read 4 scenarios (2 accidents, 1 crime, and 1 fire) imbedded in other scenarios. The scenarios were varied so that the victim is either very irresponsible or not very irresponsible, and the outcome is mild or severe. The oldest group of participants blamed the victims more than the other groups. However, in contrast to the typical severity effect, the oldest group blamed the very irresponsible victim more when the outcome was mild than they did when the outcome was severe.     

Recruitment Strategies for a Home-Based Physical Activity Intervention for Breast Cancer Patients

Recruiting cancer patients for randomized trials investigating psychosocial interventions presents several unique challenges. This paper describes the challenges and yields for different recruitment methods used in Moving Forward, a randomized trial of a home-based moderate-intensity physical activity program for early-stage breast cancer survivors. Recruitment methods included letters sent to patients by their oncologists, direct referrals from oncologists, in-person recruitment in oncology clinics, referrals from nurses and medical assistants, passive recruitment, other mailings, and community outreach strategies. Of the 424 screenings completed, 86 (20.3%) participants were randomized. Physician letters yielded the greatest number of initial screenings (147; 34.7%) and participants randomized (28; 32.5%). In-person recruitment also proved to be a productive recruitment strategy; 14 (16.3%) of the participants were recruited via this strategy. Community outreach efforts did not provide as great a yield and were labor intensive. We discuss suggestions for recruitment of cancer patients in future trials.     

Foucault, Feminism, and Informed Choice

The purpose of this paper is to show that the standard notion of informed choice is unacceptable and must be replaced. To do so, I examine Foucault's analysis of people in contemporary society, drawing attention to the ways power relations act upon us, and to the possibility of resistance. I show how feminist moral theory can be enriched by Foucault's analysis. Applying this new understanding of people and moral theory to an analysis of informed choice, I claim that the standard notion of informed choice is unacceptable, in part because it relies on a false conception of people. Its “necessary” features—intention, understanding, and absence of controlling influences—are much more difficult, if not impossible, to obtain than proponents of the standard notion believe. I end by offering direction for creating a new, Foucault-inspired, feminist theory of informed choice.     

Homelessness in the US and Germany: a cross‐national analysis

A public opinion survey was administered by telephone to nationally representative samples in the US and Germany to assess prevalence of homelessness as well as attitudes, opinions and knowledge regarding homelessness. Lower prevalence rates were found in Germany as compared with the US. German respondents demonstrated higher levels of general compassion, greater support for the public rights of the homeless, a greater tendency to view the homeless as trustworthy, and were more likely to view economic factors and less likely to view personal failings as integral to the problem of homelessness. Respondent age, gender, and political affiliation predicted many public opinion variables. Copyright © 2003 John Wiley & Sons, Ltd.
