The implications of value conflict: how disagreement on values affects self-involvement and perceived common ground

This article presents two studies demonstrating the implications of having different values (vs. interests) in a situation where people take opposite positions. Study 1 examined how people respond to a range of conflict issues that were framed either as referring to conflicting values or as referring to conflicting interests. Study 2 used a more immersive methodology, in which participants were led to consider either their values or interests in taking up a particular position, after which they were presented with a confederate who took up the opposite position. Results of both studies converge to demonstrate that framing a particular conflict issue in terms of values causes people to experience more self-involvement and to perceive less common ground. This result can be seen as a potential explanation of why value conflicts tend to escalate more easily than conflicts of interests and also offers scope for interventions directed at value conflict resolution.     

Ingestive behavior in rat pups is modified by maternal sodium depletion

Developmental programming by maternal stress during pregnancy is found to influence behavioral development in the offspring. The main objective of this study was to investigate the effect of maternal sodium depletion in rats during pregnancy on the development of thirst mechanisms in the offspring. Pregnant rats underwent 3 episodes of saline depletion, induced by injecting sc 10 mg of Furosemide in saline (0.5 ml). The treatment, given on the 14th, 17th and 20th days post-conception, is thought to induce acute sodium depletion on dams. The offspring were tested for their drinking responses to Isoproterenol (500 μg/kg sc). In accordance to the known sequence of ontogenic development of drinking mechanisms, all groups of pups drunk after being stimulated with Isoproterenol at 6 days of age. The offspring from Furosemide-treated dams drank significantly less than the control group after Isoproterenol (p<0.001). Nevertheless, basal intake (water drunk after vehicle-saline only) was also significantly lower in these pups (p<0.001). In conclusion, offspring exposed to saline depletion in utero, modify their thirst responses at 6 day of age. This confirms that in utero conditions determine thirst responses in the offspring and they could provide adaptive advantages.     

Interparental violence and children's long-term psychosocial adjustment: the mediating role of parenting practices

The objectives of this study were: (a) to examine the direct and indirect relationships among witnessing interparental violence, parenting practices, and children's long-term psychosocial adjustment; (b) to analyze the possible gender differences in the relationships specified. The sample consisted of 1295 Spanish university students (M age = 21.21, SD = 4.04). We performed statistical analyses using structural equation modeling. The results showed that witnessing parental violence as a child is related to poor long-term psychosocial adjustment during the child's adult years. Furthermore, we found that parenting practices fully mediated the relation between witnessing interparental violence and the child's long-term adjustment. The multigroup analyses showed that most of the relations among the variables did not differ significantly by gender. However, the relation between harsh discipline and antisocial behavior was stronger for males, whereas the relation between harsh discipline and depressive symptoms was stronger for females. Finally, we discuss the implications of these findings for the clinicians and specialists who plan and develop intervention programs for populations at risk.     

The Counseling Profession in Russia: Historical Roots,Current Trends,and Future Perspectives

Psychology was established in Russia before the Communist era. The social work profession was created in 1991 for a society in turmoil after the collapse of the Soviet Union. In 2011, the counseling profession officially emerged as a branch of social work called social psychological help. Professional counseling associations are in the formative stage. Concern about mental health issues, particularly substance abuse, suggests that the counseling profession could continue to grow in Russia.     

Reducing Escape without Escape Extinction: A Systematic Review and Meta-Analysis of Escape-Based Interventions

Individuals with disabilities may engage in challenging behavior to escape aversive stimuli, like academic tasks or non-preferred foods. Interventions to reduce these behaviors often employ escape extinction; that is, the implementer withholds escape following challenging behavior. Escape extinction can increase risk of injury, restrict autonomy, and worsen the learner–implementer relationship. To mitigate collateral effects, interventions can use strategies without escape extinction (i.e., escape-based); that is, implementers can provide escape contingent on challenging behavior during intervention, in conjunction with other intervention components. However, no comprehensive syntheses of these interventions have been conducted. We identified 39 articles that included escape-based interventions, which contained 273 single-case designs. Escape-based interventions were associated with lower levels of challenging behavior and higher levels of adaptive behavior than baseline conditions. Most comparisons between escape-based and escape extinction interventions showed no functional relation, indicating that escape extinction may not add substantial benefit to intervention efficacy.

Semi-wild chimpanzees open hard-shelled fruits differently across communities

Researchers investigating the evolutionary roots of human culture have turned to comparing behaviours across nonhuman primate communities, with tool-based foraging in particular receiving much attention. This study examined whether natural extractive foraging behaviours other than tool selection differed across nonhuman primate colonies that had the same foods available. Specifically, the behaviours applied to open the hard-shelled fruits of Strychnos spp. were examined in three socially separate, semi-wild colonies of chimpanzees (Pan troglodytes) that lived under shared ecological conditions at Chimfunshi Wildlife Orphanage, and were comparable in their genetic makeup. The chimpanzees (N = 56) consistently applied six techniques to open these fruits. GLMM results revealed differences in the number of combined technique types to open fruits across the colonies. They also showed colony differences in the application of three specific techniques. Two techniques (full biting and fruit cracking) were entirely absent in some colonies. This study provides empirical evidence that natural hard-shelled fruit-opening behaviours are distinct across chimpanzee colonies, differences that most likely have not resulted from ecological and genetic reasons.     

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.     

Inter-word eye behaviour during reading is not invariant to character size: Evidence against systematic saccadic range error in reading

The present study re-investigated the effect of character size on eye behaviour during reading, in order to test McConkie, Kerr, Reddix, and Zola's (1988 McConkie, G. W., Kerr, P. W., Reddix, M. D., & Zola, D. (1988). Eye movement control during reading: I. The location of initial eye fixations on words. Vision Research, 28(10), 1107–1118. doi:10.1016/0042-6989(88)90137-X[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) Saccadic Range Error (SRE) hypothesis. This assumes that saccades are biased to move the eyes a constant, optimal distance in the task (i.e., range error), while aiming at the centre of peripherally selected target words. Results showed in contradiction with this hypothesis, (1) that the linear relationship between the eye launch site and the mean landing sites in words is not invariant to character size, and (2) that the optimal launch-site distance to the centre of words varies depending on the spatial extent of the words, and differs from the mean length of saccades in the task. We propose an alternative, Center-of-Gravity hypothesis, which a priori accounts for the launch-site effect and its variations with character size, and suggests that research in reading may benefit from reconsidering the role of character size.
