From Games to Giving: Social Value Orientation Predicts Donations to Noble Causes

The central purpose of the present research is to examine the ability of social value orientation (i.e., prosocial, individualistic, and competitive orientation), as measured with methods rooted in game theory (i.e., decomposed games), to predict real-life prosocial behavior. Consistent with hypotheses, results revealed that individual differences in social value orientation are predictive of various donations. Relative to individualists and competitors, prosocials reported to engage in a greater number of donations, especially donations to organizations aimed at helping the poor and the ill. Results are discussed in terms of theory and methodology regarding the individual differences in social value orientation, as well as in terms of societal implications for enhancing donations to noble causes.     

Attention Demands in Balance Recovery following Lower Limb Amputation

The attention demands in balance control after damage to the peripheral sensorimotor system were studied in 12 persons with a recent lower limb amputation. The interference of an arithmetic task with two postural tasks of different complexity (quiet standing and active weight shifting) was examined several times during their rehabilitation while the subjects stood on a force platform. Control data were obtained from healthy subjects. For both postural tasks, persons with amputation performed worse than controls. Quiet standing, a relatively simple task, revealed clear dual-task interference only in the amputation group. Evidence was found for a reduction in dual-task interference as rehabilitation progressed. In contrast, voluntary (feedback-controlled) weight shifting, a more complex task, revealed an equal amount of dual-task interference in persons with amputation and in controls, without changes in interference over the period of rehabilitation. The results indicate that attentional mechanisms may be involved in postural control, depending on both the novelty and complexity of the task. Moreover, a reduction in attention demands of quiet standing may reflect a central adaptation of the postural organization to the peripheral sensorimotor impairments caused by lower limb amputation.     

Compositional Natural Language Semantics using Independence Friendly Logic or Dependence Logic

Independence Friendly Logic, introduced by Hintikka, is a logic in which a quantifier can be marked for being independent of other quantifiers. Dependence logic, introduced by Väänänen, is a logic with the complementary approach: for a quantifier it can be indicated on which quantifiers it depends. These logics are claimed to be useful for many phenomena, for instance natural language semantics. In this contribution we will compare these two logics by investigating their application in a compositional analysis of the de dicto - de re ambiguity in natural language. It will be argued that Independence Friendly logic is suitable, whereas Dependence Logic is not.     

Opinion Change in Time of War

Two hundred ninety-five college students were tested to determine the effects of specified variables of self-appraisal and task appraisal on achievement, self-assessment of achievement, and expended effort. Primary results were as follows: (a) The academic self-concept was found to contribute significantly to achievement on a specific task. Partial correlation between the academic self-concept and task achievement with intelligence controlled was .39 (p ≤ .05). A nonsignificant partial correlation between task confidence and task achievement with intelligence controlled was .16 (considered high enough to warrant further study). (b) Approximately two-thirds of the variance in self-assessment of achievement was found to be due to one's perceived achievement on a specific task. The variables of self-appraisal (i. e., academic self-concept and self-confidence) were not found to affect self-assessment of achievement, nor the variables of task appraisal (i. e., task confidence and task interest). Expended effort appears to have had a small part in the total variance of self-assessment of achievement. (c) Expended effort was found to be significantly related to task interest, but variables of self-appraisal did not contribute significantly to expended effort.     

Causality and the categorisation of objects and events

The “Tower of London” puzzle was adapted to tablet PCs to be used as a clinical bedside test. “Iso-problems”, a specific class of problems, require identical moves but ball colours are permuted. Thus difficulty is the same even if the appearance is different. We wanted to determine the impact of these as yet little-studied tasks and hypothesised that there may be a learning effect specific to them (the “iso-effect”). We interspersed a set of six iso-problems within one selection of 22 tasks and analysed problem solving by 81 healthy adults (mean age 41.6 years). Participants showed learning across iso-problems (less time, fewer moves, increasingly efficient solutions). This effect was distinct from general learning, as was obvious from comparison with a series of non-isomorphic tasks. However, participants seem not to be aware of solving such problems. This “iso-effect” may be related to implicit memory, a domain that so far has not been assessed using the Tower of London.     

Personal Identity in College and the Work Context: Developmental Trajectories and Psychosocial Functioning

Personal identity formation represents a core developmental challenge for adolescents and young adults. Because much of the identity literature focuses on college students, it is necessary to conduct a detailed inquiry into the ways in which specific commitment and exploration processes develop over time for college students and for employed individuals. Two samples (456 college students and 318 employed individuals) were used to identify identity status trajectories over time and to examine external correlates of these trajectories (i.e. depressive symptoms, self‐esteem, identity centrality, community integration, and sense of adulthood). Similar identity trajectories emerged in both college students and employed individuals. Four of these trajectories corresponded to Marcia's identity statuses. In addition, apart from the ‘classical’ or troubled diffusion trajectory, a carefree diffusion trajectory was also obtained. Whereas individuals on an identity‐achieved pathway fared best in terms of the outcome measures, individuals in the troubled diffusion trajectory fared worst in terms of self‐esteem, depressive symptoms, and community integration over time. Implications and suggestions for future research are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Consistent Partial Least Squares for Nonlinear Structural Equation Models

Partial Least Squares as applied to models with latent variables, measured indirectly by indicators, is well-known to be inconsistent. The linear compounds of indicators that PLS substitutes for the latent variables do not obey the equations that the latter satisfy. We propose simple, non-iterative corrections leading to consistent and asymptotically normal (CAN)-estimators for the loadings and for the correlations between the latent variables. Moreover, we show how to obtain CAN-estimators for the parameters of structural recursive systems of equations, containing linear and interaction terms, without the need to specify a particular joint distribution. If quadratic and higher order terms are included, the approach will produce CAN-estimators as well when predictor variables and error terms are jointly normal. We compare the adjusted PLS, denoted by PLSc, with Latent Moderated Structural Equations (LMS), using Monte Carlo studies and an empirical application.     

Theologian,Teacher, and Friend: Tributes to James M. Gustafson

James M. Gustafson, who died in 2021, has influenced generations of theologians and ethicists. In this article, five students, colleagues, and friends provide short reflections on what Gustafson has meant for their work as scholars of theology and religious ethics.
