Analytical Problems and Suggestions in the Analysis of Behavioral Economic Demand Curves

Behavioral economic demand curves (Hursh, Raslear, Shurtleff, Bauman, & Simmons, 1988) are innovative approaches to characterize the relationships between consumption of a substance and its price. In this article, we investigate common analytical issues in the use of behavioral economic demand curves, which can cause inconsistent interpretations of demand curves, and then we provide methodological suggestions to address those analytical issues.

We first demonstrate that log transformation with different added values for handling zeros changes model parameter estimates dramatically. Second, demand curves are often analyzed using an overparameterized model that results in an inefficient use of the available data and a lack of assessment of the variability among individuals.

To address these issues, we apply a nonlinear mixed effects model based on multivariate error structures that has not been used previously to analyze behavioral economic demand curves in the literature. We also propose analytical formulas for the relevant standard errors of derived values such as P _max, O _max, and elasticity. The proposed model stabilizes the derived values regardless of using different added increments and provides substantially smaller standard errors. We illustrate the data analysis procedure using data from a relative reinforcement efficacy study of simulated marijuana purchasing.     

Love Life: Aristotle on Living Together with Friends

According to Aristotle, the most characteristic activity of friendship is “living together” [to suzên]. This paper seeks to understand living together in the light of his famous, foundational claim that humans are social by nature. Based on an interpretation of Nicomachean Ethics 9.9, I explain our need for friends in terms of a more fundamental human need to appreciate one's life as a whole. I then argue that friendship is built into the very structure of human life itself such that human living is living together.     

Regulatory Focus and Subjective Well-Being: The Mediating Role of Coping Styles and the Moderating Role of Gender

Abstract

Although previous research has suggested that regulatory focus may exert considerable impacts on individuals’ subjective well-being (SWB), little research has explored the mechanism for this relation and the potential gender difference. The current study investigated the potential mediating effects of coping styles on the relationship between regulatory focus and three aspects of SWB (indicated by life satisfaction, positive affect, and negative affect) among Chinese adolescents. Total of 2943 Chinese adolescents participated in this cross-sectional survey and completed self-reported questionnaires (M_age = 14.47, SD?=?1.59, 44.50% boys). Hypothesized pathways were tested by structural equation models. Results showed that regulatory foci were significantly associated with SWB. Promotion focus predicted SWB mainly through problem-focused coping, and the mediating effects of emotion-focused coping were also observed; Prevention focus predicted SWB mainly through emotion-focused coping, and the mediating effects of problem-focused coping were observed. Furthermore, relative to boys, the prediction of problem-focused coping on life satisfaction was stronger and the prediction of promotion focus on life satisfaction was weaker for girls. These findings provide a new approach to understand the mechanism for the relationship between regulatory foci and SWB, and indicate the gender differences of this process.     

Discovery and a Preliminary Study of the Parallel Lines Illusion Change Effect

The parallel lines illusion change effect (discovered by the authors) was studied: When the plane of a parallel-lines illusion figure intersects obliquely with the line of vision and the figure is rotated, using an imaginary perpendicular line between the parallel lines as the axis, the smaller the intersecting angle, the more the illusory effect decreases, until it disappears. If the illusion figure is rotated and any one of the parallel lines is used as the axis, then the smaller the intersecting angle, the greater the illusory effect. The parallel lines illusion change effect may be applicable to the study of geometric-figure illusions.     

The Impact of Size of Cooperative Group on Achievement,Social Support,and Self-Esteem

The effect of cooperative learning in pairs and groups of 4 and in individualistic learning were compared on achievement, social support, and self-esteem. Sixty-two Italian 7th-grade students with no previous experience with cooperative learning were assigned to conditions on a stratified random basis controlling for ability, gender, and self-esteem. Students participated in 1 instructional unit for 90 min for 6 instructional days during a period of about 6 weeks. The results indicate that cooperative learning in pairs and 4s promoted higher achievement and greater academic support from peers than did individualistic learning. Students working in pairs developed a higher level of social self-esteem than did students learning in the other conditions.     

Political skill and emotional cue learning via voices: a training study

The ability to discern emotional expressive cues represents an important interpersonal emotional skill at the workplace. In a training study with 123 employee–peer dyads, we examined whether political skill enhances the learning of emotional expressive cues via voices. Controlling for the effects of extraversion and self‐monitoring, it was found that political skill was significantly related to the accurate recognition of emotions via voices after a training session. As predicted, other‐reported political skill was found to be a stronger predictor of such learning than self‐reported political skill. In addition, social astuteness and networking ability were the most predictive of emotional cue learning among the different dimensions of political skill. Implications and limitations are discussed.     

An Introduction to Normalization and Calibration Methods in Functional MRI

In functional magnetic resonance imaging (fMRI), the blood oxygenation level dependent (BOLD) signal is often interpreted as a measure of neural activity. However, because the BOLD signal reflects the complex interplay of neural, vascular, and metabolic processes, such an interpretation is not always valid. There is growing evidence that changes in the baseline neurovascular state can result in significant modulations of the BOLD signal that are independent of changes in neural activity. This paper introduces some of the normalization and calibration methods that have been proposed for making the BOLD signal a more accurate reflection of underlying brain activity for human fMRI studies.     

The representation of category typicality in the frontal cortex and its cross-linguistic variations

When asked to judge the membership of typical (e.g., car) vs. atypical (e.g., train) pictures of a category (e.g., vehicle), native English (N = 18) and native Chinese speakers (N = 18) showed distinctive patterns of brain activity despite showing similar behavioral responses. Moreover, these differences were mainly due to the amount and pervasiveness of category information linguistically embedded in the everyday names of the items in the respective languages, with important differences across languages in how pervasive category labels are embedded in item-level terms. Nonetheless, the left inferior frontal gyrus and the bilateral medial frontal gyrus are the most consistent neural correlates of category typicality that persist across languages and linguistic cues. These data together suggest that both cross- and within-language differences in the explicitness of category information have strong effects on the nature of categorization processes performed by the brain.
