Teacher''s locus of control and student achievement gains

Ten female fifth-grade teachers, 40 fifth-grade males, and 40 fifth-grade females were classified as internal or external (locus of control) on the basis of their scores on Rotter's (1966) Internal-External (I-E) Control Scale and the Intellectual Achievement Responsibility Questionnaire (Crandall, Katkovsky, & Preston, 1962). Measures of students' achievement and intelligence were obtained from the California Test Bureau's Short Form Test of Academic Aptitude (1970) and the Comprehensive Tests of Basic Skills (1968). The major finding of the study was that both male and female students, regardless of their locus of control, gained more on the achievement measure under internal teachers than under external teachers.     

Quantitative relations between avoidance behavior and pituitary-adrenal cortical activity

The rate at which monkeys pressed a lever and avoided shocks was manipulated in several ways. Measurements were also made of their plasma levels of 17-hydroxycorticosteroids. The rate at which the animals pressed the lever and the frequency with which they received shocks were both implicated as determiners of the steroid levels.     

Reduction of shock frequency as reinforcement for avoidance behavior

An avoidance technique was used in which rats had two levers available, with independent shock schedules associated with each. Behavioral patterns in initial conditioning and in the maintenance of the responses with various response-shock intervals led to the suggestion that reduction of shock density be considered an important variable in avoidance behavior.     

Distinguishing CEOs from Top Level Management: A Profile Analysis of Individual Differences,Career Paths and Demographics

Purpose

Identifying the characteristics of chief executive officers (CEOs) has been a longstanding goal in leadership and individual differences research. The purpose of this exploratory study was to consider which individual difference and career path variables differentiate CEOs from other senior managers.

Design/Methodology/Approach

Participants (N = 1152) were UK-based senior managers (n = 1040) and CEOs (n = 112) who completed a self-report measure of the Five Factor Model of personality (NEO-PI-R), a measure of cognitive ability (graduate and management aptitude test), and answered a number of additional questions on their career paths as part of development centres. Analyses comprised inter-individual mean difference tests, intra-individual external profile analysis and logistic regression.

Findings

Results indicated that personality facets of impulsiveness, vulnerability, activity and dutifulness showed the largest mean differences. No significant effects were found for the criterion profile pattern, but significant effects were found for profile level. Of the additional predictors, career path variables were the strongest predictors of CEO status.

Implications

The combination of significant effects across domains of individual differences and career path variables emphasizes the importance of a multivariate approach in the study of leadership, top management teams and career progression.

Originality/Value

The current study combines personality, cognitive ability, demographic and career path variables, and applies intra-individual methodologies to explore the characteristics of the very top level of organisational hierarchy.

     

Psychological individuation and spiritual enlightenment: some comparisons and points of contact

In his writings on individuation Jung often references Eastern religions and philosophies such as Buddhism, Taoism, and Hinduism. This essay discusses differences and similarities between analytical psychology's concept of individuation, especially in its advanced stages, and enlightenment as expressed in such texts as Zen (Chan) Buddhism's Ten Ox‐Herding Pictures. I advance the argument that important common features can be found while cultural differences must also be respected. There is here a convergence between West and East that can foster dialogue and mutuality.     

Sex differences in ADHD trajectories across childhood and adolescence

Previous studies have hinted at sex differences in developmental trajectories in ADHD symptoms; however, little is known about the nature or cause of these differences and their implications for clinical practice. We used growth mixture modelling in a community‐ascertained cohort of n = 1,571 participants to study sex differences in ADHD symptom developmental trajectories across the elementary and secondary school years. Participants were measured at ages 7, 8, 9, 10, 11, 12, 13, and 15. We found that females were more likely to show large symptom increases in early adolescence while males were more likely to show elevated symptoms from childhood. For both males and females, early adolescence represented a period of vulnerability characterized by relatively sudden symptom increases. Females affected by hyperactivity/impulsivity may be more likely to be excluded from diagnosis due to current age of onset criteria. More attention should be paid to early adolescence as a period of risk for hyperactivity/impulsivity symptom onset or worsening.     

The Impact of Fathers' Absence on African American Adolescents' Gender Role Development

Gender role development was assessed in 52 father-absent and 54 father-present African American adolescents. Father-present boys, especially those from lower-income backgrounds, had higher perceptions of their masculinity than did father-absent boys. Lower income father-absent girls perceived themselves to be higher in masculinity than did all other girls. Consequently, father-present adolescents tended to have more traditional gender role orientations than did those in father-absent homes. It is argued that mothers' and fathers' different socializing strategies balance out in two-parent homes. However, in father-absent homes, mothers' tendency to rely on and pressure their daughters fosters relatively more masculine girls, whereas a lack of father socialization fosters less masculine boys. Implications for theory and future research are also discussed.
