Inclusion: Considerations from social validity and Functional Outcome Analysis

Inclusion and particularly full inclusion has become a hotly debated topic. While proponents of inclusion believe that social, behavioral, academic, and developmental benefits occur for children with disabilities as well as for other, nondisabled, children in the classroom, research into inclusion provides equivocal results. This paper (a) describes inclusion, highlighting the inconsistencies in definitions and research; (b) discusses the importance of social validity in making inclusion decisions; and (c) presents an approach to inclusion using Functional Outcome Analysis (Noell & Gresham, 1993). While inclusion may be philosophically desirable, the research does not support its application as an all-inclusive approach. Inclusion decisions must be made on a case-by-case basis after a functional analysis of the student's behavior has been conducted.     

Procreative liberty, biological connections, and motherhood.

Given the complex and dramatic array of issues currently facing us in reproductive ethics, bioethicists working on the topic might be forgiven feelings of trepidation when they cast their minds toward the next century. Currently, technologies such as artificial insemination by donor (AID), once the source of intense controversy, are used on a routine basis; mainstream newspapers carry advertisements offering "excellent compensation" to ova "donors;" courts are arguing whether women who serve as gestational or "surrogate" mothers have any parental rights; and proposals resurface to jail pregnant women who take street drugs. Sorting out which developments are to be welcomed and which are to be resisted -- and why -- will require us not only to clarify some of our most basic value commitments, but also to reflect on our understanding of concepts, such as motherhood, that we previously had the luxury of thinking obvious. Let me highlight two issues I think we will be forced to confront as we try to navigate the ethics of reproduction into the twenty-first century -- namely, the value of biological connection and the meaning of motherhood.     

Handgun Ownership and the Religion Factor

This article addresses the relationship between religious affiliation and a very specific form of firearms ownership, that is, handgun ownership. Literature is reviewed relative to explanations of gun ownership. A test of the hypothesized relationship between religious affiliation and handgun ownership demonstrated a statistically significant ( p < 0.03) association. Protestants were found to have a disproportionately high level of handgun ownership compared to other religious groups. Speculation for this finding is reviewed relative to other recent research on this topic.     

Comparing Individual Behavior Plans from Schools With and Without Schoolwide Positive Behavior Support: A Preliminary Study

School-wide positive behavior support (SWPBS) has been proposed as a proactive and preventive method to reduce problematic behavior in schools. Under this approach, educators and administrators seek to create a school environment that fosters prosocial behavior and attempts to systematically deter problem behaviors before they happen. To date, the relationship between SWPBS and individualized positive behavior support (PBS) plans has not been examined. Specifically, it is unclear whether an atmosphere of SWPBS facilitates the functional behavioral assessment process and the design of PBS plans for students exhibiting severe behavior problems. The purpose of the present study was to investigate whether behavior support plans created in schools employing SWPBS systems were more technically adequate than support plans created in schools utilizing traditional approaches to behavior problems. Results indicated that support plans created at schools with SWPBS systems were more technically adequate than support plans produced at non-SWPBS schools as measured by the Behavior Support Plan-Quality Evaluation (BSP-QE). However, support plans from schools with SWPBS systems were still considered underdeveloped. Limitations and future research are discussed.     

Structure and continuity of intellectual development in early childhood

We evaluated over 200 participants semiannually from 12 to 48 months of age on measures of intellectual (Bayley Scales, Stanford–Binet Scale) and verbal (MacArthur–Bates Inventory, Peabody Picture Vocabulary Test) status. Structural equation modeling and hierarchical linear (growth curve) analyses were applied to address the nature of development and individual differences during this time. Structural analyses showed a strong and robust simplex model from infancy to the preschool period, with no evidence of qualitative reorganizations or discontinuities. Growth-curve modeling revealed significant associations between level factors across the early and later measures of cognition, providing further evidence of continuity; the growth trajectory from the Bayley through 24 months predicted growth in a nonverbal factor, but not in a verbal factor. Altogether, the findings reveal continuous and stable development in intellectual function from late infancy through the preschool years. Additionally, the high level of continuity demonstrated across these ages was observed to be largely independent of growth in vocabulary.     

Adolescents’ preferences for sexual dimorphism are influenced by relative exposure to male and female faces

Exposure to a particular population of faces can increase ratings of the normality and attractiveness of similar-looking faces. Such exposure can also refine the perceived boundaries of that face population, such that other faces are more readily perceived as dissimilar. We predicted that relatively less exposure to opposite-sex faces, as experienced by children at single-sex compared with mixed-sex schools, would decrease ratings of the attractiveness of sexual dimorphism in opposite-sex faces (that is, boys at single-sex schools would show a decreased preference for feminised faces, and girls at single-sex schools would show a decreased preference for masculinised faces). Consistent with this prediction, girls at single-sex compared with mixed-sex schools demonstrated significantly stronger preferences for facial femininity in both male and female faces. Boys at single-sex compared with mixed-sex schools demonstrated marginally stronger preferences for facial masculinity in male faces, but did not differ in their ratings of female faces. These effects were attenuated among some single-sex school pupils by the presence of adolescent opposite-sex siblings. These data add to the evidence that long-term exposure to a particular face population can influence judgements of other faces, and contribute to our understanding of the factors leading to individual differences in face preferences.     

The role of symmetry in attraction to average faces

Although many studies have demonstrated that average faces tend to be attractive, few studies have examined the extent to which symmetry contributes to the attractiveness of average faces. Such studies are potentially important, however, because average faces are highly symmetric and increasing the symmetry of face images increases their attractiveness. Here we demonstrate that increasing averageness of 2-D face shape independently of symmetry is sufficient to increase attractiveness, indicating that preferences for symmetry cannot solely explain the attractiveness of average faces. Additionally, we show that averageness preferences are significantly weaker when the effects of symmetry are controlled for using computer graphic methods than when the effects of symmetry are not controlled for, suggesting that symmetry contributes to the attractiveness of average faces. Importantly, this latter finding was not explained by the greater perceived similarity between versions offaces that varied in averageness, but not symmetry, than between versions of faces that varied in both averageness and symmetry.     

Tympanic Membrane Temperature and Hemispheric Cognitive Style

The authors tested the hypothesis that there is a correlation between hemispheric cognitive style and ear temperature. A sample of 100 participants completed a measure of hemispheric cognitive style, the Hemispheric Consensus Prediction Profile. Ear temperatures were taken in 2 sessions, 2 times for each ear at each session. Average left ear temperature was subtracted from average right ear temperature as an index of dominant temperature. Only 56 of the participants showed a stable dominant ear temperature. For these 56 participants, there was a statistically significant positive correlation between scores on the Hemispheric Consensus Prediction Profile and tympanic member temperature (Spearman's ρ =.29, 95% CI [.04,.51]). Individuals with a left hemispheric cognitive style tended to have a warmer left tympanic membrane temperature while those with a right hemispheric cognitive style tended to have a warmer right tympanic membrane temperature. Tympanic membrane temperatures are easily obtained using inexpensive and noninvasive technology. The relationship suggested by these findings may open new opportunities for the study of cerebral asymmetry.     

Using leap motion to investigate the emergence of structure in speech and language

In evolutionary linguistics, experiments using artificial signal spaces are being used to investigate the emergenceof speech structure. These signal spaces need to be continuous, non-discretized spaces from which discrete unitsand patterns can emerge. They need to be dissimilar from—but comparable with—the vocal tract, in order tominimize interference from pre-existing linguistic knowledge, while informing us about language. This is a hardbalance to strike. This article outlines a new approach that uses the Leap Motion, an infrared controller that canconvert manual movement in 3d space into sound. The signal space using this approach is more flexible than signalspaces in previous attempts. Further, output data using this approach is simpler to arrange and analyze. Theexperimental interface was built using free, and mostly open- source libraries in Python. We provide our sourcecode for other researchers as open source.
