Personality and organizational culture as determinants of influence

How can individuals attain influence in organizations? Prior research has identified structural determinants of influence, such as formal authority and position in a social network. However, indirect evidence suggests that influence might also stem from personal characteristics. The authors tested whether influence can stem from the fit between the person and his or her organization (P-O fit). Consistent with expectations, extraverts attained more influence in a team-oriented organization, whereas conscientious individuals attained more influence in an organization in which individuals worked alone on technical tasks. Further, these effects held up after controlling for formal authority, job performance, and demographic characteristics, such as gender, ethnicity, and socioeconomic status. The multiple ways in which individuals can gain influence are discussed.     

A hierarchical approach for fitting curves to response time measurements

Understanding how response time (RT) changes with manipulations has been critical in distinguishing among theories in cognition. It is well known that aggregating data distorts functional relationships (e.g., Estes, 1956). Less well appreciated is a second pitfall: Minimizing squared errors (i.e., OLS regression) also distorts estimated functional forms with RT data. We discuss three properties of RT that should be modeled for accurate analysis and, on the basis of these three properties, provide a hierarchical Weibull regression model for regressing RT onto covariates. Hierarchical regression model analysis of lexical decision task data reveals that RT decreases as a power function of word frequency with the scale of RT decreasing 11% for every doubling of word frequency. A detailed discussion of the model and analysis techniques are presented as archived materials and may be downloaded from www.psychonomic.org/archive.     

An Invitation to Behavior Analysts: Review of in Search of Memory: The Emergence of A New Science of Mind by Eric R. Kandel

This fascinating autobiography and multifaceted case history in neuroscience research is accessible to laymen and potentially instructive to working scientists. Kandel takes the reader through his thought processes as he describes experiments that led to some of the past decades'' major neuroscience discoveries (some highlights of which are summarized in the review''s Appendix), and eventually to his Nobel Prize. The review analyzes some of the terminological and conceptual issues that have often inhibited communication between behavior analysts and neuroscientists, with special attention to some of Bennett and Hacker''s admonitions viewed from the perspective of language evolution and linguistics. The review then discusses opportunities for behavior analysts to collaborate with neuroscientists by applying behavioral contingency analysis to help specify the independent variables of neuroscience experiments described by Kandel. Finally, it examines Kandel''s provocative heuristics for locating important research problems, and the lessons that can be gleaned from the book regarding the attributes of potentially great achievers.     

Diffusion model analysis with MATLAB: A DMAT primer

The Ratcliff diffusion model has proved to be a useful tool in reaction time analysis. However, its use has been limited by the practical difficulty of estimating the parameters. We present a software tool, the Diffusion Model Analysis Toolbox (DMAT), intended to make the Ratcliff diffusion model for reaction time and accuracy data more accessible to experimental psychologists. The tool takes the form of a MATLAB toolbox and can be freely downloaded from ppw.kuleuven.be/okp/dmatoolbox. Using the program does not require a background in mathematics, nor any advanced programming experience (but familiarity with MATLAB is useful). We demonstrate the basic use of DMAT with two examples.     

Safeguarding Tradition: Psychological Type Preferences of Male Vergers in the Church of England

The current study explores the psychological type profile of vergers within the Church of England. A sample of 42 male vergers completed the Myers-Briggs Type Indicator (Form G). The study shows that vergers tend to prefer introversion over extraversion, sensing over intuition, thinking over feeling, and judging over perceiving. The type preferences of vergers are compared and contrasted with the type preferences of clergy and laity. These findings are explored within the context of the role of the verger within the Church of England.     

Stimulus preference assessments and the utility of a moderate category

Recent studies have shown that moderate (Piazza, Fisher, Hagopian, Bowman, & Toole, 1996 ) and low (Taravella, Lerman, Contrucci, & Roane, 2000 ) ranked items on stimulus preference assessments may function as reinforcers. Following an initial preference assessment the current study analyzed whether moderate or low preference items were more likely to be ranked as high preference on subsequent preference assessments. Results show that for five of the seven participants additional high preference items were identified from the moderate preference set, while additional high preference items were identified from the low preference set for only one participant. Results are discussed in terms of the need to identify multiple reinforcers and the composition of the stimulus array during preference assessment. Copyright © 2006 John Wiley & Sons, Ltd.     

A revised semantic differential scale distinguishing between negative and positive God images

A sample of 755 school pupils between the ages of 11 and 18 years completed the Benson and Spilka semantic differential measure of God images. Factor analysis indicated the advantages of re‐scoring the measure as an eight item unidimensional index, defining semantic space relating to God images ranging from negative affect to positive affect.     

Gender Differences in Campaign Materials and Politicians’ Professional Orientation: The Case of a Hong Kong Election

This study examines gender differences in election campaigns with a specific focus on whether professional orientation, defined as the extent to which a politician sees politics as a career with its own ladder of advancement, would suppress gender differences. This is because candidates with higher levels of professional orientation may tend to see themselves primarily as “politicians” instead of as women or men. A content analysis of 836 candidates’ campaign leaflets in a local level election in Hong Kong was conducted. The results show some differences in the extent to which women and men candidates mentioned certain issues and used certain appeals in their platforms. However, when gender differences existed, they were more pronounced among candidates with weaker professional orientation.     

Kidnapping: a criminal profile of persons convicted 1979-2001

Kidnapping has been a neglected crime in criminological research. In fact, there has been a dramatic increase in the yearly numbers of police recorded kidnapping offences in England and Wales in the last 25 years, but this has not been matched by a similar increase in convictions. This study focuses on the official criminal histories of the 7042 males and 545 females who were convicted at least once for kidnapping between 1979 and 2001. Of these, 3.9% of the males and 2.6% of the females had convictions for kidnapping on more than one occasion.We examined two subgroups to ensure long observation periods for prior and subsequent convictions. Of those convicted of kidnapping in 2001, around one-half (51.1%) of the males and around one-third (36.6%) of the females had previous convictions. The previous convictions consist of a wide range of offences, with the most common being theft and violent offences. A 20-year follow-up of those convicted in 1979-81 showed that three in five males and one in three females are subsequently convicted on at least one more occasion for a standard-list offence.An examination of convictions for other offences brought to court at the same time as the kidnap offence enabled a typology of kidnaps to be proposed. Those kidnaps with co-convictions of an acquisitive nature declined over the period, whereas other types, including sexual and violent, showed rises. Changing shifts in the nature of kidnaps have important policy implications.
