初级指挥官人格类型与PM领导行为类型有效性的关系

通过对陆军初级指挥官人格心理类型与领导行为有效性的心理学研究 ,探讨个人的领导潜能、人格心理类型对领导行为有效性的影响。研究发现 :1方差分析表明 ,具有不同领导行为的指挥官在人格维度上存在明显的统计学差异。提示了指挥官的领导行为取向与人格因素有密切的关系。2卡方分析结果也表明 ,PM型行为的军官在其人格特征上具有“ESTJ”组合特征 ,而 pm型的军官则正好相反 ;另外 ,pm型的军官在成就动机上获得高分的人数最少。3系统聚类分析显示 ,“成就动机”、“感觉”和“判断”三种人格因素与军事指挥官完成整体领导职能有着更为密切的关系。     

Perceptual comparisons of adolescent stutterers' and nonstutterers' fluent speech

Numerous investigators have reported that listeners are able to perceptually differentiate adult stutterers' and nonstutterers' fluent speech productions. However, findings from similar studies with children ranging in age from 3 to 9 yr have indicated that perceptual discrimination of child stutterers is difficult. A logical extension of this line of investigation would be to determine when during maturation from childhood to adulthood stutterers' fluent speech becomes perceptibly different than nonstutterers'. Therefore, in this study similar fluent speech samples from seven 12–16-yr-old adolescent male stutterers and seven matched nonstutterers were analyzed perceptually in a paired stimulus paradigm by 15 sophisticated listeners. Individual subject analyses using signal detection theory revealed that five of the seven stutterers were discriminated. When averaged for subject group comparison, these findings indicated that listeners successfully discriminated between the fluent speech of the two groups. Therefore, the perceptual difference in fluent speech production reported previously for adults appears to be present by adolescence.     

Developmental Delays at Arrival,Early Intervention Enrollment,and Adopted Chinese Girls’ Academic Performance and Internalizing Problems in Adolescence

The author investigated the extent of developmental delays in girls adopted from China, their subsequent early intervention (EI) enrollment, and how the delays and EI were related to their academic performance and internalizing problems in adolescence. The sample included 180 adolescent girls (M = 13.4 years, SD = 2.0 years) who were adopted at 3–23.5 months (M = 11.5 months, SD = 3.7 months). Data on the adopted Chinese girls’ delays at arrival and EI enrollment in physical therapy (PT) and speech–language therapy (SLT) were collected from the adoptive mothers at the Baseline; data on the adopted Chinese girls’ present academic performance and internalizing problems were collected from the adoptive mothers and adopted girls at Wave 4 six years later. Data analyses revealed that 55% of the adoptees had moderate-to-severe delays when first arrived at the adoptive homes. Motor delays significantly increased the odds for PT (odds ratio [OR] = 3.98, 95% CI [2.18, 7.82], p <.001) and SLT (OR = 2.36, 95% CI [1.50–3.72, p <.001). Social-cognitive delays also significantly increased the odds for PT (OR = 1.90, 95% CI [1.36, 2.63], p <.001) and SLT (OR = 1.63, 95% CI [1.22, 2.17], p <.001). Motor delays were negatively associated with academic performance but positively associated with internalizing problems. General linear modeling showed that the adoptees who had developmental delays at arrival and subsequently enrolled in EI scored significantly lower on academic performance than their peers who had delays but did not enroll in EI, as well their peers who had no delays and did not enroll in EI. Implications of these findings are discussed.     

Teacher perceptions of stuttering

The attitudes of 521 teachers in the Tuscaloosa, Alabama City School (82% of the teacher population) toward stuttering were assessed using the Teachers' Perceptions of Stuttering Inventory (TPSI). The TPSI consists of five teacher identification questions and 10 attitudinal statements about which teachers are asked to indicate their strength of agreement. Results indicated that a significant number of teachers hold unsubstantiated beliefs concerning the etiology of stuttering and the personality characteristics of stutterers. Teachers having experience with stutterers or having had course work in speech disorders indicated more realistic attitudes toward stutterers and expressed more demanding attitudes toward stutterers in the classroom situation. In view of the potential positive role teachers can play in assisting stutterers, the results were interpreted as suggesting a need for teachers to receive either preservice or inservice instruction with respect to the problem of stuttering.     

Examining legalism,scrupulosity, family perfectionism,and psychological adjustment among LDS individuals

This study examined the relationships and interactions between legalism, scrupulosity, family perfectionism, guilt, and shame among 421 Latter-Day Saints (LDS or Mormons). The results showed that scrupulosity fully mediated the links between legalism and guilt, as well as legalism and shame. A moderated-mediation effect was found, in which family discrepancy (maladaptive perfectionism) intensified the scrupulosity–shame association in the mediation model of legalism and shame by scrupulosity. Family discrepancy was not a significant moderator for the mediation model of legalism and guilt by scrupulosity. Additional results are provided and implications of these findings are outlined.
