Children's Conformity When Acquiring Novel Conventions: The Case of Artifacts

Prior research focused on children's acquisition of arbitrary social conventions (e.g., object labels) has revealed that both 3- and 4-year-old children conform to majority opinion. Two studies explored whether children show similar conformist tendencies when making category-based judgments about a less socially arbitrary domain that offers an objective basis for judgment: object functions. Three- and 4-year-old children watched a video in which two informants disagreed with a lone dissenter on the function of a novel artifact. Children were asked to categorize the object by stating with whom they agreed. The plausibility of the majority's response was manipulated across test trials. Results demonstrated that children were more likely to agree with the majority when majority and minority opinions were equally plausible, especially when the majority demonstrated an overt consensus. However, 4-year-olds actively eschewed the majority opinion when it was implausible in context of the artifact's functional design. The current results indicate that expertise in a domain of conventional knowledge reduces conformist tendencies.     

Where you look can influence haptic object recognition

We investigated whether the relative position of objects and the body would influence haptic recognition. People felt objects on the right or left side of their body midline, using their right hand. Their head was turned towards or away from the object, and they could not see their hands or the object. People were better at naming 2-D raised line drawings and 3-D small-scale models of objects and also real, everyday objects when they looked towards them. However, this head-towards benefit was reliable only when their right hand crossed their body midline to feel objects on their left side. Thus, haptic object recognition was influenced by people's head position, although vision of their hand and the object was blocked. This benefit of turning the head towards the object being explored suggests that proprioceptive and haptic inputs are remapped into an external coordinate system and that this remapping is harder when the body is in an unusual position (with the hand crossing the body midline and the head turned away from the hand). The results indicate that haptic processes align sensory inputs from the hand and head even though either hand-centered or object-centered coordinate systems should suffice for haptic object recognition.     

Disclosure of Genetic Research Results to Members of a Founder Population

There is currently extensive discussion and debate in the literature on how, when, and to whom genetic research results should be returned (see Genetics in Medicine, April 2012 issue). Here, we describe our experience in disclosing genetic information on Mendelian disorders discovered during the course of our research in the Hutterites. We first assessed attitudes toward the disclosure of carrier results, which revealed that many individuals wanted carrier information and that many intended to use the information in family planning. Based on this information, we developed a pilot study to test and disclose cystic fibrosis (CF) carrier status. Next, a larger scale project was developed in order to disclose genetic research results for 14 diseases to those interested in receiving the information. We developed brochures, offered a live interactive educational program, conducted a consent process, and disclosed results in letters mailed to the consented individuals. Overall, ~80 % of individuals who participated in the educational program signed consent forms for the release of their results for 14 diseases. We describe our experience with returning individual genetic research results to participants in a population-based research study.     

Egocentric reference frame bias in the palmar haptic perception of surface orientation

The effect of egocentric reference frames on palmar haptic perception of orientation was investigated in vertically separated locations in a sagittal plane. Reference stimuli to be haptically matched were presented either haptically (to the contralateral hand) or visually. As in prior investigations of haptic orientation perception, a strong egocentric bias was found, such that haptic orientation matches made in the lower part of personal space were much lower (i.e., were perceived as being higher) than those made at eye level. The same haptic bias was observed both when the reference surface to be matched was observed visually and when bimanual matching was used. These findings support the conclusion that, despite the presence of an unambiguous allocentric (gravitational) reference frame in vertical planes, haptic orientation perception in the sagittal plane reflects an egocentric bias.     

Caught Between Two Worlds: Sexuality and Young Muslim Women in Melbourne,Australia

Existing research suggests that culture has a significant influence on the sexuality of culturally and linguistically diverse communities in Australia. However, few studies have explored the influence of both religion and culture on sexuality of young Muslim women. This paper qualitatively examines the influence of Islam, Muslim culture and Australian culture on the sexuality of young Muslim women in Melbourne, Australia. This research employed an in-depth interview technique to gather data on the lived experiences of 11 young Muslim women. The findings revealed a marked influence of religion and culture on the sexuality of young Muslim women. Additionally, this study highlights the challenges that young Muslim women face in regards to balancing Muslim culture, Australian culture and Islamic religion. This study contributes to knowledge about the lived experiences of young Muslim women in Australia regarding meanings of sexuality and the difficulties they have in balancing the influences of religion and culture. This knowledge can be useful for the provision of sexual health care that reflects a culturally and religiously sensitive approach for young Muslim women in Australia and elsewhere.     

Condoms,Sex, and Sexually Transmitted Diseases: Exploring Sexual Health Issues Among Asian-Indian College Students

Sexually transmitted infections (STIs) continue to pose a serious risk to college students in the US. According to the Centers for Disease Control, the highest rates of STIs are among college students and adolescents. Specifically regarding Asian-Indian students, more research is needed to thoroughly understand the knowledge, attitudes and sexual behaviors of this population. A comprehensive review of the literature found a paucity of studies involving Asian-Indian involvement in sexual activity. Therefore, the present study was undertaken to fill gaps in the research. The present study examined Asian-Indian college students’ involvement in sexual behaviors, overall STI knowledge, condom use rate, perceived benefits and barriers to condom use, and history of STIs and STI testing. A five page survey was completed by 122 Asian-Indian college students. Results indicated that overall STI knowledge was low. Females, students who perceived fewer barriers to condom use and students who had lived in the US for at least 3 years held significantly higher STI knowledge levels than their counterparts. Such findings could be used by community and university-based health educators to more effectively serve the needs of Asian-Indian students.     

Domesticated dogs’ (Canis familiaris) use of the solidity principle

Organisms must often make predictions about the trajectories of moving objects. However, often these objects become hidden. To later locate such objects, the organism must maintain a representation of the object in memory and generate an expectation about where it will later appear. We explored adult dogs’ knowledge and use of the solidity principle (that one solid object cannot pass through another solid object) by evaluating search behavior. Subjects watched as a treat rolled down an inclined tube into a box. The box either did or did not contain a solid wall dividing it in half. To find the treat, subjects had to modify their search behavior based on the presence or absence of the wall, which either did or did not block the treat’s trajectory. Dogs correctly searched the near location when the barrier was present and the far location when the barrier was absent. They displayed this behavior from the first trial, as well as performed correctly when trial types were intermingled. These results suggest that dogs direct their searches in accordance with the solidity principle.     

Longitudinal changes in college math students’ implicit theories of intelligence

This study examined changes over time in implicit theories of intelligence and their relationships to help-seeking and academic performance. College algebra students completed questionnaires during the second week of classes and 2 weeks before the end of the semester (ns = 159 and 145, respectively; 61 students completed questionnaires at both waves). The questionnaires assessed entity and incremental implicit theories of general and math intelligence (beginning and end of semester) and help-seeking (end of semester). Results indicated that students had more incremental views of general than math intelligence. Further, their views became less incremental over the course of the semester; however, this decrease was greater for math than for general intelligence. Participants who exhibited a stronger incremental theory of general intelligence at the beginning of the semester subsequently reported greater help-seeking during the semester. Finally, students who had more entitative views of math intelligence earned lower course grades.
