Personal values as a mediator between parent and peer expectations and adolescent behaviors.

The current study examined the mediating role of adolescents' personal values on the relation between maternal and peer expectations for prosocial behaviors and adolescents' self-reported prosocial and antisocial behaviors. One hundred thirty-four adolescents (mean age = 16.22 years, 54% girls) completed measures of their own values and behaviors, as well as their perceptions of the positive expectations that their mother and their best friend(s) had for their (the adolescents') prosocial behaviors. Stepwise regression analyses suggested that adolescents' personal prosocial values mediated the relation between adolescents' perceptions of both maternal and peer expectations and adolescents' prosocial behaviors. In addition, for boys, perceptions of positive peer expectations were directly and negatively related to antisocial behaviors. The current study has important implications for parents, educators, and practitioners who are concerned about promoting adolescents' positive behaviors and discouraging negative behaviors.     

Oxytocin Receptor (OXTR) Single Nucleotide Polymorphisms Indirectly Predict Prosocial Behavior Through Perspective Taking and Empathic Concern

Engaging in prosocial behavior can provide positive outcomes for self and others. Prosocial tendencies contribute to the propensity to engage in prosocial behavior. The oxytocin receptor gene (OXTR) has also been associated with prosocial tendencies and behaviors. There has been little research, however, investigating whether the relationship between OXTR and prosocial behaviors is mediated by prosocial tendencies. This relationship may also vary among different types of prosocial behavior. The current study examines the relationship between OXTR, gender, prosocial tendencies, and both altruistic and public prosocial behavior endorsement. Students at a midwestern university (N = 398; 89.2% Caucasian; M_age = 20.76; 26.6% male) provided self‐report measures of prosocial tendencies and behaviors and buccal cells for genotyping OXTR polymorphisms. Results indicated that OXTR single nucleotide polymorphism (SNP) rs2268498 genotype significantly predicted empathic concern, whereas gender moderated the association between several other OXTR SNPs and prosocial tendencies. Increased prosocial tendencies predicted increased altruistic prosocial behavior endorsement and decreased public prosocial behavior endorsement. Our findings suggest an association between genetic variation in OXTR and endorsement of prosocial behavior indirectly through prosocial tendencies, and that the pathway is dependent on the type of prosocial behavior and gender.     

The effect of in-vehicle warning systems on speed compliance in work zones

The purpose of this research was to evaluate the effectiveness of augmented in-vehicle speed warnings on driver behavior in work zones. The influence of three device configurations were examined as the drivers entered a work zone which was presented in a simulated driving environment. The first configuration was a control condition which used only traditional signage. The second condition had the addition of a visual in-vehicle warning while the final condition had the addition of an auditory in-vehicle warning. Results indicated that adding in-vehicle warnings did affect driver compliance to the work zone speed limit. Participants in the audio warning condition responded more quickly to the warning than those in the visual condition. Both augmented warning configurations differed significantly and were each respectively different from the drivers in the control condition. Based on these results we suggest a combination of in-vehicle warnings. Upon entry of the work zone we suggest a combined audio and visual warning message. However, after the initial entry phase, a visual warning message shows greater promise for the on-going modulation of driver speed transit.     

Effects of long-term blindness on preparatory emg modulation in humans performing landing movements

To investigate the long-term effect of blindness on the task of leaping down to a lower landing surface, five blind individuals were compared with 10 sighted individuals who performed landing movements with and without sight. Participants performed six consecutive drop-landings from four different heights, during which the prelanding modulation of EMG timing and amplitude in four lower-limb muscles were recorded. Analysis showed that blind individuals showed specific prelanding EMG modulation, suggesting that long-term dependence on somesthetic and vestibular cues leads to different preparatory measures for vertical falls.     

Analyzing Anti‐Asian Prejudice From a Racial Identity and Color‐Blind Perspective

The purpose of this study was to examine to what extent both racial identity and color‐blind racial attitudes help explain anti‐Asian prejudice across different socioracial groups. Participants of color from a culturally diverse West Coast university were surveyed (N = 260). Hierarchical regression analyses showed that resistance racial identity and color‐blind attitudes predicted anti‐Asian prejudice. Results further validated racial identity theory as a viable tool for understanding interracial relations among Asians and other socioracial minority groups.     

Early detection of drug use and bullying in secondary school children by using a three-dimensional simulation program

The current study analyzes the psychometric properties of an innovative three-dimensional (3D) simulation program, entitled Mii-School (MS), designed for the early detection of drug use and bullying in Secondary School children. This computer program showed adequate reliability and construct validity. The factorial structure, as well as the explanatory weight of the different factors, is presented. In addition, the results of a parallel version in paper and pencil format are also presented and compared with those of the computerized version (i.e., MS). There was a statistically significant difference between the two formats in the total (i.e., combined) sore of risk. When drug use and bullying were separately analyzed, differences were found only with regard to drug use. The relevance of these results as well as the suitability of this type of 3D instrument for the early detection of risky behaviors in young people are discussed.     

Visual laterality in belugas (Delphinapterus leucas) and Pacific white-sided dolphins (Lagenorhynchus obliquidens) when viewing familiar and unfamiliar humans

Lateralization of cognitive processes and motor functions has been demonstrated in a number of species, including humans, elephants, and cetaceans. For example, bottlenose dolphins (Tursiops truncatus) have exhibited preferential eye use during a variety of cognitive tasks. The present study investigated the possibility of visual lateralization in 12 belugas (Delphinapterus leucas) and six Pacific white-sided dolphins (Lagenorhynchus obliquidens) located at two separate marine mammal facilities. During free swim periods, the belugas and Pacific white-sided dolphins were presented a familiar human, an unfamiliar human, or no human during 10–15 min sessions. Session videos were coded for gaze duration, eye presentation at approach, and eye preference while viewing each stimulus. Although we did not find any clear group level lateralization, we found individual left eye lateralized preferences related to social stimuli for most belugas and some Pacific white-sided dolphins. Differences in gaze durations were also observed. The majority of individual belugas had longer gaze durations for unfamiliar rather than familiar stimuli. These results suggest that lateralization occurs during visual processing of human stimuli in belugas and Pacific white-sided dolphins and that these species can distinguish between familiar and unfamiliar humans.     

Facial Feature Assessment of Popular U.S. Country Music Singers Across Social and Economic Conditions

The facial features of the artists of the top Country Billboard song for each year from 1946 to 2010 were investigated across changes in U.S. socioeconomic conditions. When conditions were relatively poor, country music artists with more mature facial features of smaller eyes and larger chins were popular, and when conditions were more prosperous, country music artists with more baby-faced features of larger eyes and smaller chins were popular. Results extend previous findings with pop singers, movie actresses, and Playboy Playmates, and suggest the social and economic environment influences preferences for country singers across time.     

Evaluating the use of preparation guides in interteaching versus a quiz alternative

Interteaching is a behavioral teaching method that has demonstrated efficacy in higher education. Of particular interest is the use of a preparation guide (a guided reading assignment), which is designed to promote engagement in the other areas of the interteaching process. The present study compared the use of a preparation guide completed before the start of class with that of a quiz administered at the start of the class. The quiz was hypothesized to serve as a functional alternative to the preparation guide. A total of 38 undergraduate students enrolled in an Introduction to Psychology course participated in this study. The primary dependent measure was student performance on tests following each condition. The analysis revealed no statistically significant difference between the conditions, F(1, 302) = 0.103, p = .748, though qualitative feedback revealed student preference for preparation guides. Future research is necessary to examine the effects of quizzing while addressing the limitations of this study.     

Athletes’ Preferred Characteristics and Qualifications of Sport Psychology Practitioners: A Consumer Market Analysis

Studies assessing the perceived characteristics of competent sport psychology practitioners have resulted in skewed data, making it difficult to discern the relative importance of each characteristic. Therefore, the purpose of this study was to assess the attributes of gender, ethnicity, interpersonal skills, physical appearance, athletic background, professional status, and sport culture in relation to one another using conjoint analysis, a consumer market analysis. College student athletes (N = 464) indicated a preference for a female practitioner whose ethnicity matched that of the athlete and possessed high interpersonal skills and sport knowledge, an athletic background, a physically fit body type, and had earned a professional degree. These findings can be used by sport psychology consultants to modify the information they give to current clients and to develop marketing plans to appeal to potential clients.
