The stability of callous-unemotional (CU) traits and both individual and contextual factors that influence this stability have been studied in community adolescent samples but not to great extent in adolescents who have been arrested. We estimated the developmental changes in CU traits measured over the course of 36 months (6-month intervals)…

The present study explored how life satisfaction changes before and after childbirth among first-time parents from a nationally representative, longitudinal study of Germans. Life satisfaction increased before pregnancy to a peak just after birth and then returned to the baseline level within 2 years postpartum. The 2 members of the same couple…

The study examined individual factors and social factors that influence adolescent students' achievement in mathematics. The predictive model suggested direct positive effects of student intelligence, self-rated openness and parental education on achievement in mathematics, whereas direct effects of extraversion on measures of achievement were…

Previous research has established that a relationship exists between the personality trait of conscientiousness and academic achievement. The current study extends prior research by using a path analysis model to explore various proximal traits that may mediate this relationship in a sample of two hundred and twenty three undergraduate university…

The assumption that effective leaders differ in some identifiable and fundamental ways from other people is still a large part of mainstream I/O psychology. Based on a research review on the trait theory of leadership and what is known about the concept of expertise, this paper attempts to find a convergence between leader and expert traits.…

In 1921, Carl Jung wrote about four different types of personality, identified 24 centuries ago by Hippocrates. He theorized that these differences were not abnormalities in personality. Instead, he maintained that human behavior is predictable and classifiable that everyone has and acts upon personal preferences, established in early childhood.…

While past research has documented the independent effects of individual difference characteristics and contextual information on perceptions of leadership, it has not investigated the simultaneous effects. This study explored the interactive effects of these factors under the hypothesis that dispositional characteristics should be more strongly…

Because most studies investigating psychological profiles of subjects convicted of driving under the influence of alcohol (DUI) have been conducted at the time of arrest or treatment, it is unclear whether subjects' anxiety, depression, and hostility represent "trait" characteristics central to alcohol abuse or "state"…

The authors conclude that the differences outlined in this study are quite apparent in working with honors and nonhonors students. Classes with honors students are characterized by a freedom of thought and behavior rarely found outside that group. The same kinds of behavior pervade their social relationships also. (Author)

Suggests we attend to aspects of our interpersonal environment that correspond to features of our personality. Subjects who weighted a particular dimension tended to think they possessed a personality trait corresponding to the dimension. Reasons for the individual difference hypothesis were given. (Author)

The Sixteen Personality Factor questionnaire and the California Psychological Inventory were administered to (N=42) Roman Catholic seminarians and (N=42) male Protestant divinity students. Data analysis indicated that the Catholics were significantly more dependent, more group-reliant, more feminine, less assertive, and less-accepting than the…

Employees classified into development and research groups were contrasted for differences in vocational interest and personality inventory responses. Discriminant and classification analyses indicated that these two groups could be distinguished. Development personnel exhibited greater interests in supervisory-related areas, but researchers showed…

Seven simulation games were played and evaluated by twenty-six graduate students as part of a course in simulation/gaming. Each student also completed the Myers-Briggs Type Indicator, a personality type inventory which assigns each person to one of 16 types based on their placement on each of four dichotomous dimensions. The students' evaluation…

While some people have difficulty adjusting to retirement, others seem to adjust easily. The search for theory to explain the source of positive retirement may require research methods to develop theory rather than to test theory. Grounded theory methodology was used to determine the characteristics and sources of characteristics of adults who had…
