Comparison of Korean and European women professional golfers' training time and perceptions of ideal training time

The purpose of this study was to compare Korean and European female professional golfer's reported practice hours and their different understandings about golf training. 55 Korean and 21 European female professional golfers were asked questions about average actual practice days per week, average actual practice hours per day, ideal practice days per week, and ideal practice hours per day. All the women participated in the Korean Female Masters Golf Tournament at the Korean Cyprus Golf course from 6-8 November in 2009. Korean female professional golfers reported practicing more hours, but both the Korean and European golfers reported actually practicing more hours than their ideal practice hours.     

Trait anxiety among students in a college golf class

This study examined trait anxiety among students (N=80) participating in a beginning golf activity class. Analysis showed no differences in anxiety scores by sex or playing experience; however, performance differences were noted as students with moderate scores performed better on golf evaluations than did those with high anxiety scores. Research should be directed to assess students' perceptions of anxiety and its effects.     

The Effect of Motor-Mental Preperformance Routines on Motor Performance in Novice Learners

Two sequential studies were conducted to test the notion that preperformance routines (PPRs) positively affect motor performance. The first study consisted of observations and interviews with 115 elite athletes to explore crucial time periods and body positions inherent in expert preparation for performing a golf putt, tennis serve, volleyball serve, and basketball free throw. In the second study, we taught these features of PPR to novice performers: 240 male and female high school students were assigned to two motor-mental PPR, and one control condition. Findings revealed that PPR enhances motor performance and can be implemented at an early stage of learning.     

Relatedness Support and the Retention of Young Female Golfers

In this study, self-determination theory was used as a guiding framework to understand the putative role of relatedness support for retention in golf among young females. Data were collected using semi-structured interviews with 10 female participants (M_age = 21.40, SD = 3.13). Content analyses revealed 5 distinct factors that contributed to the provision of relatedness support: Parents, Peers, Coaches, Golf Club, and Institutional and Societal Support. Findings highlighted that retention of female golfers may be facilitated through promoting valued relationships with parents, peers, coaches, and golf clubs. Policies that decrease the perceived marginalization of female participants may also be perceived as a form of relatedness support and may promote retention within this cohort. This study underscores the importance of relatedness support for young women and identifies strategies that may help to improve female retention in sport.     

Ratings of emotion in laterally presented faces: sex and handedness effects

Sixteen right-handed participants (8 male and 8 female students) and 16 left-handed participants (8 male and 8 female students) were presented with cartoon faces expressing emotions ranging from extremely positive to extremely negative. A forced-choice paradigm was used in which the participants were asked to rate the faces as either positive or negative. Compared to men, women rated faces more positively, especially in response to right visual field presentations. Women rated neutral and mildly positive faces more positively in the right than in the left visual field, whereas men rated these faces consistently across visual fields. Handedness did not affect the ratings of emotion. The data suggest a positive emotional bias of the left hemisphere in women.     

Classroom Interactions: Gender of Teacher,Gender of Student,and Classroom Subject

An observational study investigated the effects of gender of teacher, gender of student, and classroom subject (mathematics vs. English literature/language) on teacher–student interactions. A total of 597 high school students (294 males and 303 females) and 36 teachers (28 males and 8 females) were observed in either 18 mathematics classes or 18 literature/language classes. Students and teachers were predominately Caucasian, with the majority of students from a lower- or middle-class background. Observations were coded using the interactions for sex equity in classroom teaching (INTERSECT) observational instrument. It was found that female mathematics teachers, male literature/language teachers, and female literature/language teachers tended to interact somewhat more with male students than with female students. This tendency was not the result of male students having initiated more direct verbal interactions with teachers.     

Rock Stars in Anti‐Drug‐Abuse Commercials: An Experimental Study of Adolescents' Reactions1

Two studies examined adolescents' perceptions and effectiveness of rock stars in antidrug‐abuse public‐service announcements (PSAs). In the pilot study (N= 24 teenagers), adolescents expected rock musicians, and in particular heavy metal musicians, to be drug users. In our experimental study (N= 78 high school students aged 15 to 16 years), one group was shown 4 PSAs produced by Rock Against Drugs, using rock stars Jon Bon Jovi, Aimee Mann, Gene Simmons, and Belinda Carlysle as spokespersons. The comparison group was shown 4 equivalent PSAs that were created using unknown actors selected for their similarity to the rock stars in terms of age, ethnicity, and gender, but without any reference to rock music. PSA ratings were taken on 4 scales: attractiveness, expertness, trustworthiness, and overall PSA rating. Pretest and posttest measures of drug attitudes supported our hypotheses that countermessages from rock stars denormalize the connection between rock music and drugs, and that adolescents respond more positively to PSAs with rock stars than to PSAs without rock stars.     

Preferences for sexual dimorphism on attractiveness levels: An eye-tracking study

Previous studies on sexual dimorphism showed feminine preferences in female faces and mixed findings in male faces by choosing which is more attractive in a pair of a masculine face and a feminine face. However, very little is known about how people make fine-grained visual assessments of such images and the attractiveness levels of faces are not received much attention. Recently a large number of androgynous stars appear in the media, which triggers a hot phenomenon of imitating them. Here we examine the influence of androgynous stars on people’s facial preferences for sexual dimorphism in male and female faces on different attractiveness levels using eye-tracking techniques. In male faces we found both male and female participants preferred masculine faces to androgynous faces in high attractiveness, but mixed results in low attractiveness. In female faces we found both male and female participants preferred feminine faces to androgynous faces in high attractiveness, but no preferences in low attractiveness. Results suggest that attractiveness levels of faces might be a factor causing inconsistency in sexual dimorphism preference for male faces and that androgynous faces are not preferred, which reveals that androgynous phenomenon might not be caused by facial attractiveness.     

Driving distance and driving accuracy equals total driving: reply to Dorsel and Rotunda

DIFFERENTIALLY REINFORCING LOW RATES OF MISBEHAVIOR WITH NORMAL ELEMENTARY SCHOOL CHILDREN1

Effective nonpunitive procedures for reducing counterproductive classroom behaviors are of potential benefit to both students and teachers. A recent strategy for dealing with this class of problem behaviors involves the reinforcement of acceptably low levels of such behavior. The laboratory version of this procedure, called differential reinforcement of low rates of responding (or DRL), provides for a reinforcer to be delivered contingent upon a response that is separated from the last preceding response by a minimum amount of time. To make this procedure more amenable to classroom use, the present authors have modified it so that a reinforcer is delivered if fewer than a specified number of responses occur within a preset time interval (Deitz and Repp, Journal of Applied Behavior Analysis, 1973, 6 , 457–463). Previous studies using this procedure have found it effective in reducing and maintaining low rates of targeted behaviors. However, these effects have been demonstrated with groups of subjects and/or individuals from dependent populations. The present study investigated use of this modified DRL procedure with individual students in normal elementary classrooms. In the first of three studies, “talk-outs” of an 11-yr-old fifth-grade male were reduced when nonexchangeable gold stars were made contingent on two or fewer responses per session. During baseline sessions, an average of 4.45 talkouts were observed per 45-min session. Average responding subsequently fell to 1.83 when the modified DRL contingency was applied, increased to 7.60 during a reversal phase, and dropped again to an average of 1.20 when the contingency was reapplied. In the second study, out-of-seat behavior of a 12-yr-old sixth-grade female was reduced when gold stars were made contingent on two or fewer responses per 45-min class period. Baseline responding averaged 6.10 responses per session. When the contingency was applied, average responding fell to 0.16. During the reversal period, responding increased to an average of 6.00 and fell again, after the contingency was re-introduced to an average of 0.40. In the third study, a reduction in both talking-out and out-of-seat behaviors of another 11-yr-old fifth-grade male was demonstrated with a multiple-baseline design. Using different lengths of baselines, gold stars were made contingent first on a low rate of out-of-seat behavior, and then on a low rate of talk-outs. Out-of-seat responding fell from a baseline average of 7.50 to a treatment average of 1.14. Talk-outs went from a baseline average of 4.66 to a treatment average of 1.14. In all three studies, the modified DRL procedure proved effective with the children and was manageable by the classroom teacher. For the students, nonexchangeable conditioned reinforcers (stars) were sufficient to maintain lowered rates of inappropriate behavior with the modified DRL schedule; there was no need for an elaborate token economy, a process that in many cases may be only a form of behavioral “overkill”. As in other studies investigating DRL schedules, students were not informed of their accumulation of responses; the differential effects of providing or withholding this feedback need to be investigated. Overall, these studies add single-subject replication with normal children to the literature on modified DRL procedures.     

Neurophysiological evidence of how quiet eye supports motor performance

Prolonged quiet eye (QE) duration is associated with greater performance in various types of targeting and interceptive tasks. However, the mechanism by which QE affects performance remains debatable. This study aimed to test the validity of the pre-programming and online control hypotheses using electromyography (EMG), electrooculography (EOG) and electroencephalography (EEG) during a golf putting task. Twenty-one college students were recruited for this study. Each participant performed 100 golf putting trials during which the putting performance, EMG, EOG, and EEG signals were recorded. The QE duration including the pre- and post-movement initiation components, and movement-related cortical potentials (MRCPs) were analyzed off-line. We found that successful putts were associated with longer QEtotal (the total QE duration from QE onset to QE offset), QEpre (QE occurring before movement initiation), and QEpost (QE occurring after movement initiation) durations than failed putts. Greater cortical activation in the MRCPs was observed within the prefrontal, premotor, and parietal cortices during successful putts compared with failed putts. These findings suggest that QE serves both pre-programming and online control roles in supporting golf putting performance.

     

Model Reinforcement in Group Counseling with Elementary School Children

This study investigated the effectiveness of model reinforcement and reinforcement group counseling with elementary school children using sociometric status as a criterion. Eighteen low sociometric students experienced group counseling with sociometric stars included as models (six groups); 18 others experienced group counseling with all low sociometric students (three groups); and a control group met for an activity period. An analysis of co-variance was computed to measure the difference of change in social acceptance among the three treatments. The findings indicated that low sociometric students in the model reinforcement groups made significantly more gain in social acceptance than either those receiving counseling without models or the control group. A two-month follow-up showed the sociometric gains were retained.     

Sexual harassment on campus: Effects of professor gender on perception of sexually harassing behaviors

Undergraduate students viewed four videotaped vignettes that depicted potentially sexually harassing interactions between professors and students. Subjects were asked to evaluate the professor's behavior. The vignettes were composed so that two dimensions were manipulated: the sex of the initiator of the behavior and the type of behavior. Results of the study provided partial support of the following hypotheses: (1) the behaviors of female professors initiating potentially sexually harassing behaviors toward male students would be perceived as more appropriate than would the same behaviors initiated by male professors toward female students in identical situations; (2) female subjects would interpret the behaviors as more harassing than male subjects; and finally (3) subtle forms of harassment would be interpreted as more inappropriate by female students than by male students.     

Mental imagery combined with physical practice of approach shots for golf beginners

Recent research on motor skills of golf have pointed to the usefulness of mental imagery. In golf, such training is rarely used as a teaching technique for beginners on the grounds that only top professionals stand to gain from mental imagery. This study tested whether mental imagery combined with physical practice can improve golf performance for the approach shot. 23 volunteer beginners, 8 women and 15 men, M age 23.4 yr. (SD = 3.7), enrolled in the University Physical and Sporting Activities Department, were divided into three groups, using a combination of physical practice of the approach shot plus mental imagery, physical practice only, and a third group engaging in various sporting activities instead of either mental or physical practice of the chip shot. Analysis showed that the beginners' approach shot performance improved most in the group combining physical practice and mental imagery when compared with the group just physically practising the approach shot. It seems mental training can be used effectively to improve performance even with beginners.     

Sex differences in student dominance behavior in female and male professors' classrooms

Measures of verbal participation and interaction among graduate students provided a comparison of male and female dominance behavior in the classroom, and measures of the contextual effect of sex of professor provided further data on the interrelatedness of sex, status, and dominance behavior. Male students were found to exhibit significantly more aggressiveness (interruptive behavior) than female students in both male and female professors' classes, although significantly more male aggressiveness occurred in female professors' classes than in male professors classes. Male students were significantly more assertive (frequency and duration of speech) in female professors' classes only. In student-to-student interaction, aggressiveness was predominantly exchanged between sexes rather than among same-sex members.The author would like to thank Julie Parks and Joanie Rubin for their help with this research.

Bullying and victimization: prevalence and relationship to gender, grade level, ethnicity, self-esteem, and depression

This study investigated the prevalence of bullying and victimization among students in grades 7 and 8. It also explored the relationship of bullying and victimization to gender, grade level, ethnicity, self-esteem, and depression. Three survey instruments were used to obtain data from a convenience sample of 454 public school students. Twenty-four percent reported bullying involvement. Chi-square tests indicated significantly more male than female bullying involvement, seventh graders reported more involvement than did eighth graders, and there were no statistically significant differences in involvement based on ethnicity. Both bullies and victims manifested higher levels of depression than did students who were neither bullies nor victims. There were no significant differences between groups in terms of self-esteem.

1993至2016年医学生心理健康变迁的横断历史研究

为考察我国医学生心理健康水平随年代的变迁趋势, 运用横断历史研究的方法, 对1993至2016年间181篇采用90项症状自评量表(SCL-90)测量医学生心理健康水平的研究报告(被试为129613名医学生)进行元分析。研究发现：(1)除恐怖因子外, SCL-90其余8个因子均与年代呈显著负相关, 这说明, 我国医学生的心理健康水平在逐年提升。(2)当年和5年前的2个社会指标(卫生总费用和注册医师数)与SCL-90的8个因子均值呈显著负相关, 说明这些社会指标可能是预测医学生心理健康水平的重要因素。(3)与男生相比, 女生心理健康水平的上升趋势更为明显, 但心理健康水平的性别差异并不显著。(4)医学新生心理健康水平的上升趋势要比非新生更明显和全面。     

The Accuracy of Academic Gender Stereotypes

This research assessed the accuracy of academicgender stereotypes. Approximately 9% of participantswere nonwhite (mostly African American and Hispanic).Participants' estimates of the percentage of female and male students and their GPAs were comparedto the actual percentage of female and male students andtheir actual GPAs in 12 majors. Participantssignificantly underestimated the percentage of female students regardless of the gendertype of themajor. Females and males made more accurate percentageestimates for gender-congruent majors. Participantsoverestimated the GPAs of male students significantly more than the GPAs of female students. This wasespecially pronounced for masculine majors. Althoughfemale participants estimated the GPAs of their in-groupmore accurately than the GPAs of the out-group, the reverse was true for male participants. Theimplications of this evidence for inaccurate genderstereotypes regarding academic competence arediscussed.
