Using visual reinforcement to establish stimulus control of responding of Siamese fighting fish (Betta splendens)

Stimulus control of ring swimming was studied with male Siamese fighting fish (Betta splendens) using 2-component multiple schedules in which the components were correlated with the presence or absence of air bubbles in the water. In Experiment 1, either response-independent mirror presentations or extinction was juxtaposed with immediate response-dependent mirror presentations. Rates of ring swimming generally were higher with immediate reinforcement than with either response-independent mirror presentations or extinction. In Experiment 2, different durations of response-dependent mirror presentations were juxtaposed. Generally, higher rates of ring swimming occurred with 15-s than with 0-, 1-, or 3-s durations. Results demonstrate that stimulus control of responding can be established with these fish under several conditions of differential reinforcement.     

Appreciation as Audience Response: Exploring Entertainment Gratifications Beyond Hedonism

This article elaborates upon the notion of media enjoyment in the context of film viewing by proposing a complementary type of gratification that we conceptualize as appreciation. Three studies were conducted to tap into the multidimensionality of viewers' entertainment gratifications with a special focus on the domain of more serious, poignant, and pensive media experiences typically associated with genres such as drama, history, documentary, or art films. These studies provide evidence of and measurement for gratifications related to fun and suspense, but also gratifications related to moving and thought‐provoking entertainment experiences, with all three gratifications leading to perceptions of entertainment having a more long‐lasting or enduring effect. The results are discussed with regard to the theoretical conceptualization of entertainment gratification.     

The Sign Redeemed: A Study in Christian Fundamental Semiotics

A Christian engagement with the question of the nature of the sign has to begin in a theology of the creation. Signs exhibit features of both reference and address. The meaning of the incarnation is that in a world of God's making the referring signs which constitute the world also implicitly function as divine address. The words of institution of the Lord's Supper, taken as an integral part of the Passion narrative, are the fulfilment of this addressive function of the world and thus also mark the point at which the Church is constituted as the human community who are called to receive the divine address.     

Ant Colony Optimization and Local Weighted Structural Equation Modeling. A Tutorial on Novel Item and Person Sampling Procedures for Personality Research

Measurement in personality development faces many psychometric problems. First, theory‐based measurement models do not fit the empirical data in terms of traditional confirmatory factor analysis. Second, measurement invariance across age, which is necessary for a meaningful interpretation of age‐associated personality differences, is rarely accomplished. Finally, continuous moderator variables, such as age, are often artificially categorized. This categorization leads to bias when interpreting differences in personality across age. In this tutorial, we introduce methods to remedy these problems. We illustrate how Ant Colony Optimization can be used to sample indicators that meet prespecified demands such as model fit. Further, we use Local Structural Equation Modeling to resample and weight subjects to study differences in the measurement model across age as a continuous moderator variable. We also provide a detailed illustration for both tools with the Neuroticism scale of the openly available International Personality Item Pool – NEO inventory using data from the UK sample (N = 15 827). Combined, both tools can remedy persistent problems in research on personality and its development. In addition to a step‐by‐step illustration, we provide commented syntax for both tools. © 2019 European Association of Personality Psychology
