An analysis of streaky performance on the LPGA Tour

A study investigated the occurrence of streakiness among professional golfers on the LPGA Tour. For players, individually or as a group, the findings showed a significant tendency for players' par or better rounds to occur together and for players' above par rounds to occur together. However, the observed streakiness in players' scores was related to the difficulty of golf courses rather than to any inherent disposition of players' performances to be streaky. The results replicated those findings found on the PGA Tour and Senior PGA Tour.     

Parity of match play: an LPGA replication

This study investigated whether the slight advantage of higher seeded players to win in match play on the men's Professional Golfers' Association Tour generalizes to the Ladies Professional Golf Association Tour. Analysis showed no significant advantage for the higher seeded player in match play. The highly restricted range of skill of tour players makes it mainly a matter of chance who will win any match-play event or who will have the better or worse scores on any given day.     

The beauty of match play

This study investigated whether higher seeded players have an advanage in the only match play event on the PGA Tour. Analysis showed that the higher seeded won 54% of the time (p=.06); the correlation was .17 (p<.01) between higher seeded players winning and the difference in World Rankings between players. Given professional golfers are at the highest end of the distribution of golf ability, these players are so nearly equal in ability, it is mainly a matter of chance who will win a match play event or who will have the best round on any given day.     

Students' Machiavellianism and motives for communicating with instructors

This study investigated the relationship between scores of college students (N=210, 114 women, 95 men, 1 unidentified; Mage=19.3 yr., SD=2.8) on Machiavellianism and their motives for communicating with their instructors in the classroom. Students' Machiavellianism scores were positively but weakly related to three motives of Functional (r=.22, p<.01), Excuse-making (r=.16, p<.05), and Sycophancy (r=.17, p<.05).     

A sense of presence and self-reported performance in international teams

Research over the last two decades has explored the relationship between a variety of states of consciousness, performance, and motivation. These have included flow and a sense of presence in face-to-face, online, and virtual environments. This study examined the relationship between presence and flow experienced by 75 male and female participants from several Pacific Rim nations on 4 international teams and their self-reported performance, enjoyment, and motivation associated with team-related tasks. The results indicate that in these task situations, which are relatively novel because of their cultural diversity, self-reported performance correlated more highly with presence (r=.34, df=72, p<.01) than flow (r=.26, df=71, p<.05). Enjoyment and motivation, however, correlated more highly with flow (r =.60, df=71, p<.01 and r=.40, df=71, p<.01, respectively) than presence (r=.26, p<.05 and r=.25, p<.05). These findings suggest the need to explore further the relationship between activity- or task-related states of consciousness, the characteristics of the tasks involved, particularly in terms of their novelty, and the effect on performance and motivation.     

A profile of adolescent alcohol offenders in two rural Midwestern counties

Screening tools specifically developed for use with adolescents may be more sensitive predictors of relapse or recidivism than self-report inventories typically used to screen adults. 70 adolescents in a program for drunk drivers in two counties in southeastern Nebraska were given both the CRAFFT and the Alcohol Use Disorder Identification Test questionnaires during routine alcohol-dependency evaluations. The Michigan Alcoholism Screening Test was also given to 28 subjects selected at random. 11 boys and 6 girls did not successfully complete the program. Significant correlations obtained for AUDIT scores for both the CRAFFT (r69=.65, p<.01) and failure to complete diversion (r69=.23, p<.05). Subjects were grouped by age (18 and younger and over 18 years) and by sex. A 2 x 2 analysis of variance for scores on the AUDIT indicated significant main effects for both age (F1,66=4.86, p<.05) and sex (F1.66=5.96, p<.01). MAST and CRAFFT scores showed no age or sex differences. The AUDIT might be included in drug and alcohol assessments with similar samples of adolescents.     

3~4岁幼儿创造性人格与气质的交叉滞后分析

以幼儿创造性人格倾向教师评定问卷、儿童气质教师评定问卷作为研究工具,对287名3岁和4岁组幼儿进行为期一年的追踪研究,考察幼儿气质与创造性人格的发展变化情况,以及幼儿气质与其创造性人格之间的关系。结果发现：随着时间的发展,幼儿气质对其创造性人格有显著影响。幼儿的情绪性、活动性、反应性及专注性均能够显著正向预测其创造性人格,而幼儿的社会抑制性则能够显著负向预测其创造性人格。     

Comparison of two creativity style measures

The purpose of this study was to examine the relation between two measures of creativity style for a sample of beginning teachers. 116 student teachers enrolled in an undergraduate teacher-education program in a medium-sized, metropolitan university completed the Kirton Adaption-Innovation Inventory and Basadur Creative Problem Solving Profile measures. A preference for an Innovator style (higher scores on Kirton's inventory) was correlated with the Generator profile on the Basadur profile (r=.36, p<.01). The KAI Efficiency scores, suggesting a preference for broad, global ideas as opposed to narrow, specific ones, was correlated with the Basadur Conceptualizer scores (r=.26, p<.01). Implications are discussed for teachers who must adapt to newer instructional and assessment methods designed to foster students' higher-level thinking skills.     

An examination of the "hot hand" in professional golfers

A study investigated the "hot hand" among professional golfers. Hole-to-hole scores within 747 tournaments from a randomly chosen group of 35 players on the 1997 PGA Tour were analyzed. Contingency analyses gave no evidence for the "hot hand". Players were just as likely to score a birdie or better following a par or worse hole as make a birdie or better following a birdie or better hole. These results are consistent with those found for individual players in baseball and basketball.     

Low heart rate variability is not caused by typical neuroleptics in schizophrenia patients

Both elevated cardiovascular mortality and low cardio-vagal (parasympathetic) heart rate variability (HRV)--a risk factor for postmyocardial infarction--are reported in schizophrenia (SZ). Since a number of medications have strong effects of cardiac conductivity, we thought it important to examine if typical neuroleptic medications might also affect HRV. We examined cardiac vagal activity during both neuroleptic treatment and a drug-free condition in seven SZ patients who were participating in a pilot double-blind, crossover study of placebo and haloperidol treatment. Twenty-four-hour Holter electrocardiograms were analyzed for high frequency HRV, quantitated as the percent of successive normal interbeat intervals greater than 50 milliseconds (PNN50), which is a good index of parasympathetic cardiac modulation. The patients showed unchanged PNN50 (8.4+/-9.5 versus 8.3+/-10.5; t=.22, df=6, P=.5) between the haloperidol treatment and drug-free conditions. Despite the elapsed time, change in medication, and altered clinical state, the PNN50s were highly correlated (Spearman r=.98, P=.000). SAPS positive symptom scores declined with treatment from 12.8+/-6.5 to 8.5+/-3.5; paired t=3.26: df=6; P=.01. PNN50s were significantly associated with positive (r=-.86, df=6, P=.012) and negative symptom scores (r=-.87, df=6, P=.01). We found low cardiovagal modulation in medication-free SZ patients that was associated with core SZ symptoms and was unchanged by haloperidol and benztropine treatment. The reduced HRV in SZ patients at baseline may render them at greater cardiovascular risk than healthy subjects when treated with medications having strong cardiovascular effects.     

Relationships between mood state, time estimation, and selected movement speed

We investigated whether different aspects of mood state influence sense of time estimation and movement speed. Mood states were measured on the Multiple Mood Scale for 142 female undergraduate students, who were then asked to estimate the interval of time elapsed between the words "start" and "stop" spoken by a tester. Next, the same subjects were told to draw circles inside 1-cm squares printed on an A4 size sheet of paper in succession at their freely elected comfortable speed. Scores on Concentration (r=-.22, p<.01) and Being Startled (r=-.26, p<.01) each correlated significantly and negatively with time estimation, while scores on Boredom (r =.17, p <.05) had a significant positive correlation with movement speed. These results suggest that different aspects of mood state have some association with time estimation and selected movement speed. Values account for small common variance.     

Prefrontal cognitive ability, intelligence, Big Five personality, and the prediction of advanced academic and workplace performance

Studies 1 and 2 assessed performance on a battery of dorsolateral prefrontal cognitive ability (D-PFCA) tests, personality, psychometric intelligence, and academic performance (AP) in 2 undergraduate samples. In Studies 1 and 2, AP was correlated with D-PFCA (r=.37, p<.01, and r=.33, p<.01, respectively), IQ (r=.24, p<.05, and r=.38, p<.01, respectively), and Conscientiousness (r=.26, p<.05, and r=.37, p<.01, respectively). D-PFCA remained significant in regression analyses controlling for intelligence (or g) and personality. Studies 3 and 4 assessed D-PFCA, personality, and workplace performance among (a) managerial-administrative workers and (b) factory floor workers at a manufacturing company. Prefrontal cognitive ability correlated with supervisor ratings of manager performance at values of r ranging from .42 to .57 (ps<.001), depending on experience, and with factory floor performance at pr=.21 (p=.02), after controlling for experience, age, and education. Conscientiousness correlated with factory floor performance at r=.23.     

儿童期心理虐待对青少年网络欺负的影响:领悟社会支持及性别的调节作用

近年来,网络欺负现象逐渐成为网络心理学研究的热点问题。青少年网络欺负的发生率约为60.8%,且每年都在呈增长的趋势,这对青少年正常的学习生活造成了严重的影响。故本研究主要探讨儿童期心理虐待对青少年网络欺负的影响,以及领悟社会支持和性别起到的调节作用。本研究以447名青少年作为被试(男生205人,女生242人,被试年龄范围为11~17岁,平均年龄为14.17±1.35岁),采用儿童期心理虐待量表、网络欺负问卷及领悟社会支持量表进行调查。运用SPSS 22.0及AMOS 21.0统计软件进行数据处理,Harman单因素法表明,本研究不存在严重的共同方法偏差问题。研究结果表明:(1)儿童期心理虐待与领悟社会支持呈显著负相关(r=-.14,p<.01),儿童期心理虐待与青少年网络欺负呈显著正相关(r=.44,p<.01),领悟社会支持与青少年网络欺负呈显著负相关(r=-.15,p<.01);(2)结构方程模型显示,模型各指标均达到了临界值(χ^2/df=2.67,GFI=.90,TLI=.91,CFI=.92,RMSEA=.07);(3)儿童期心理虐待对青少年网络欺负具有显著的正向预测作用(β=.21,p<.01),领悟社会支持对青少年网络欺负具有显著的负向预测作用(β=-.11,p<.05),同时,儿童期心理虐待与领悟社会支持的交互项对青少年网络欺负具有显著的负向预测作用显著(β=-.19,p<.01),简单斜率检验表明,对于低领悟社会支持水平的青少年,儿童期心理虐待对网络欺负有显著的正向预测作用(β=.54,p<.001);对于高低领悟社会支持水平的青少年,儿童期心理虐待对网络欺负的预测作用不显著(β=-.17,p>.05);(4)儿童期心理虐待与性别的交互项对青少年网络欺负具有显著的正向预测作用(β=.28,p<.001),简单斜率检验表明,对于男青少年,儿童期心理虐待对网络欺负有显著的正向预测作用(β=.54,p<.001);对于女青少年,儿童期心理虐待对网络欺负的预测作用不显著(β=.13,p>.05);由此可说明,儿童期心理虐待是青少年网络欺负出现的助推机制,而领悟社会支持和性别是青少年网络欺负出现的抑制机制,它可以弱化儿童期心理虐待对青少年网络欺负造成的创伤。     

The relationship between rational thinking and intelligence in children

This study ws designed to evaluate the efficacy of a four-session REE curriculum and examine the relationship between intelligence and the endorsement of irrational beliefs in elementary school children. A twotailedt-test administered to examine difference between pre- and post-test scores onThe Idea Inventory was statistically significant,t (1,94)=5.90,p<.0001. The Pearson product-moment correlation coefficient between pre-test scores onThe Idea Inventory and theOtis-Lennon School Ability Test failed to reach significance (r=.15) suggesting higher intelligence did not predict greater endorsement of rational beliefs. The post-test scores using the same two instruments reached a correlation coefficient of r=.51 and was statistically significant at the .01 level. A higher percentage of children who scored below the mean on theOtis-Lennon improved from pre- to post-test than children who scored above the mean.

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

Combining two primary golf skills (Driving Distance and Driving Accuracy) into one golf skill variable (Total Driving) yielded a more powerful relationship between Professional Golf Association (PGA) Touring Professionals' shot-making skills and their performance outcomes.     

Are European and American golf players different? Reply to Engelhardt (1997)

Analysis of 1998 statistics for individual performance in the PGA European Tour yielded significant differences between some shot-making skills (drive distance, total driving, greens in regulation, and sand saves) between the top 10 and bottom 10 money winners, replicating (with partially different results) a result found for the 1995 American PGA Tour by Engelhardt.     

Evidence for the construct validities of the Beck Youth Inventories with child psychiatric outpatients

To provide further information about the construct validities of the Beck Youth Inventories of Emotional and Social Impairment, these inventories were administered to 35 female and 65 male outpatients whose ages ranged from 7 to 12 years and who were diagnosed with various psychiatric disorders. The Children's Depression Inventory was also administered, and the children were rated by a parent with the Conners' Parent Rating Scale-Revised: Short Form. The scores on the former inventory were more positively correlated with the scores on the Beck Youth Depression Inventory (r =.81, p<.001) than with scores on the four other Beck Youth Inventories, and those on the Conners Oppositional scale were comparably correlated with the scores on the Beck Youth Disruptive Behavior (r=.49, p<.001) and Anger (r=.41, p<.001) Inventories. These latter correlations were higher than those for scores on the Oppositional scale with the scores on the three other Beck scales.     

THE VALIDITY OF A MEASURE OF JOB COMPATIBILITY IN THE PREDICTION OF JOB PERFORMANCE AND TURNOVER OF MOTION PICTURE THEATER PERSONNEL

The predictive validity of a measure of job compatibility was studied for theater personnel. Scores on a forced-choice instrument, developed from the Job Compatibility Questionnaire (JCQ), predicted employee performance (r = .22, p< .05), turnover (r = -.35, p< .01), and scores on a "value composite" (reflecting a combination of job performance and employee retention criteria) as defined by the research sponsor (P = .41, p< .01). Furthermore, job compatibility scores explained a statistically significant increment in turnover and value composite score variance when analyzed concomitantly with verbal and numerical ability test scores. Finally, job compatibility scores were shown to be nonredundant with hiring decisions based on an application review, reference check, and interview, whereas the cognitive ability test scores shared considerable redundancy with hiring decisions based on the current selection system.     

Discriminative game-related statistics between basketball starters and nonstarters when related to team quality and game outcome

The aim of the present paper was to examine the differences in game-related statistics between basketball players who are selected for the starting five of the team (starters) and those who are not (nonstarters) when related to game outcome (winning and losing) and team quality (best teams, teams classified for the playoffs; and worst teams, teams who miss playoff classification). Archival data were gathered for all 2002-2003 regular season games from the Portuguese Professional League (N = 156). Discriminant analysis was used to identify the game-related statistics that differentiate between starters and nonstarters and interpreted by the examination of the structure coefficients (SC). When the best teams won the games, results described differences between starters and nonstarters with an emphasis on defensive rebounds (SC = .32), assists (SC = .32) and committed fouls (SC = -.68). When the worst teams won the games, results described differences between starters and nonstarters with an emphasis on 2-point field goals successful (SC = .47) and unsuccessful (SC = .48), defensive rebounds (SC =.39), successful free throws (SC =.32), and committed fouls (SC = -.55). An also important finding was that, in best teams, the nonstarters' performance was worse in the games that the team lost, whereas in worst teams, it was the starters' performance that was worse in the games that the team lost.
