The antecedents and correlates of agreeableness in adulthood

Data from a 25-year prospective study of 194 individuals indicated that teacher and peer reports of aggression, compliance, and self-control at age 8 distinguished high-agreeable from low-agreeable adults at age 33. Profile analyses revealed two behavioral types in childhood and two personality types in adulthood, with considerable continuity in the composition of these high- and low-agreeable types over time. High-agreeable childhood types had fewer disobedience and concentration problems than low-agreeable childhood types, and among boys, high-agreeable childhood types had better school grades and fewer behavior problems than their low-agreeable counterparts. High-agreeable adulthood types reported less alcoholism and depression, fewer arrests, and more career stability than did low-agreeable adulthood types.     

Discrimination of intentional and random motion paths by pigeons

Twelve pigeons (Columba livia) were trained on a go/no-go schedule to discriminate between two kinds of movement patterns of dots, which to human observers appear to be "intentional" and "non-intentional" movements. In experiment 1, the intentional motion stimulus contained one dot (a "wolf") that moved systematically towards another dot as though stalking it, and three distractors ("sheep"). The non-intentional motion stimulus consisted of four distractors but no stalker. Birds showed some improvement of discrimination as the sessions progressed, but high levels of discrimination were not reached. In experiment 2, the same birds were tested with different stimuli. The same parameters were used but the number of intentionally moving dots in the intentional motion stimulus was altered, so that three wolves stalked one sheep. Despite the enhanced difference of movement patterns, the birds did not show any further improvement in discrimination. However, birds for which the non-intentional stimulus was associated with reward showed a decline in discrimination. These results indicated that pigeons can discriminate between stimuli that do and do not contain an element that human observer see as moving intentionally. However, as no feature-positive effect was found in experiment 1, it is assumed that pigeons did not perceive or discriminate these stimuli on the basis that the intentional stimuli contained a feature that the non-intentional stimuli lacked, though the convergence seen in experiment 2 may have been an effective feature for the pigeons. Pigeons seem to be able to recognise some form of multiple simultaneously goal-directed motions, compared to random motions, as a distinctive feature, but do not seem to use simple "intentional" motion paths of two geometrical figures, embedded in random motions, as a feature whose presence or absence differentiates motion displays.

Contextual memory deficits observed in mice overexpressing small conductance Ca2+-activated K+ type 2 (KCa2.2, SK2) channels are caused by an encoding deficit

Hippocampal-dependent synaptic plasticity and memory are modulated by apamin-sensitive small conductance Ca2+-activated K+ (SK) channels. Transgenic mice overexpressing SK2 channels (SK2+/T mice) exhibit marked deficits in hippocampal memory and synaptic plasticity, as previously reported. Here, we examined whether SK2 overexpression affects the encoding or retention of contextual memory. Compared with wild-type littermates, SK2+/T mice exhibited significantly less context-dependent freezing 10 min and 24 h after conditioning. Interestingly, this contextual memory impairment was eliminated if SK2+/T mice were permitted longer pre-exposure to the conditioning chamber. These data support converging evidence that SK2 channels restrict the encoding of hippocampal memory.     

Improving the peer-review process for grant applications: reliability, validity, bias, and generalizability

Peer review is a gatekeeper, the final arbiter of what is valued in academia, but it has been criticized in relation to traditional psychological research criteria of reliability, validity, generalizability, and potential biases. Despite a considerable literature, there is surprisingly little sound peer-review research examining these criteria or strategies for improving the process. This article summarizes the authors' research program with the Australian Research Council, which receives thousands of grant proposals from the social science, humanities, and science disciplines and reviews by assessors from all over the world. Using multilevel cross-classified models, the authors critically evaluated peer reviews of grant applications and potential biases associated with applicants, assessors, and their interaction (e.g., age, gender, university, academic rank, research team composition, nationality, experience). Peer reviews lacked reliability, but the only major systematic bias found involved the inflated, unreliable, and invalid ratings of assessors nominated by the applicants themselves. The authors propose a new approach, the reader system, which they evaluated with psychology and education grant proposals and found to be substantially more reliable and strategically advantageous than traditional peer reviews of grant applications.     

Career Adapt-Abilities Scale-Italian Form: Psychometric proprieties with Italian preadolescents

During preadolescence children start to give attention to the future, to formulate thoughts, and to wonder about what they want. They also acquire knowledge and experiment with strategies to assist them in designing their future career. Among the constructs that can now play a relevant role in life designing, the four resources of career adaptability have a prominent role. This article reports the psychometric properties of the Italian version of the Career Adapt-Abilities Scale-International Form 2.0 for a group of middle school students. Two different studies involving Italian preadolescents were conducted. The first study tests the instrument's multidimensional structure, internal consistency and discriminant validity. The second one verifies the factorial structure's across-gender invariance and the test–retest reliability. Results provide strong psychometric support for the CAAS-Italian Form with preadolescents as a valid measure for analyzing their career adaptability and for using it in career counseling and education.     

Tully and de Soto on Uniformity and Diversity

James Tully sees the emergence of modern constitutionalism as the intellectual legacy of writers such as Hobbes, Bodin and Locke. For Tully, modern constitutionalism not only centralizes authority, it also excludes diversity. Tully's work represents a significant part of the growing antipathy towards uniformity and the universalising tendencies of the modern organization, which, he believes, underwrite a loss of local empowerment. In this respect his thinking and that of the communitarians is consistent with contemporary disenchantment with, not to mention resistance to globalization. Globalization, or the tendency to inter-national uniformity in culture and increasing integration into a global system of economics and power, appears to promote an analogous universalising conformity across borders, while centralizing economic if not political power and control in certain trans-national corporations. Hernando de Soto, the Peruvian economist, gives us a very different perspective on the motley of overlapping jurisdictions and argues that diversity of systems, customs and rules with respect to property has conspired to maintain the entrenched poverty of the developing world. He argues that it is the unified, codified and integrated systems of the West that have allowed these societies to mobilize capital to escape the endemic widespread poverty of the pre-capitalist age. In the course of this paper I seek to compare and evaluate the competing claims of Tully and de Soto.
