Gaussian variational estimation for multidimensional item response theory

Multidimensional item response theory (MIRT) is widely used in assessment and evaluation of educational and psychological tests. It models the individual response patterns by specifying a functional relationship between individuals' multiple latent traits and their responses to test items. One major challenge in parameter estimation in MIRT is that the likelihood involves intractable multidimensional integrals due to the latent variable structure. Various methods have been proposed that involve either direct numerical approximations to the integrals or Monte Carlo simulations. However, these methods are known to be computationally demanding in high dimensions and rely on sampling data points from a posterior distribution. We propose a new Gaussian variational expectation--maximization (GVEM) algorithm which adopts variational inference to approximate the intractable marginal likelihood by a computationally feasible lower bound. In addition, the proposed algorithm can be applied to assess the dimensionality of the latent traits in an exploratory analysis. Simulation studies are conducted to demonstrate the computational efficiency and estimation precision of the new GVEM algorithm compared to the popular alternative Metropolis–Hastings Robbins–Monro algorithm. In addition, theoretical results are presented to establish the consistency of the estimator from the new GVEM algorithm.     

Nostalgia motivates pursuit of important goals by increasing meaning in life

This research focused on existential and motivational implications of the emotion of nostalgia. Nostalgia (relative to control) increased meaning in life, which, in turn, galvanised intentions to pursue one's most important goal (Experiment 1) and to pursue one's most important, but not least important, goal (Experiment 2). The basic pattern held in two cultures (British and Danish) independently of positive affect. This is the first evidence that nostalgia has specific motivational consequences (i.e., pursuit of more, but not less, important goals) and transmits these consequences via meaning in life. Also, this is the first evidence that meaning is associated with specific motivational consequences. Discussion considers the relevance of the findings for the emotion and motivation literatures.     

Not Simply in the Eye of the Beholder: Authenticity as a Product of Candidate Preference and Unfettered Speech

Authenticity has emerged over recent decades as a prominent theme in both the press and in political research—and peaked in the 2016 presidential contest that pitted Donald Trump against Hillary Clinton, Bernie Sanders, Marco Rubio, and Ted Cruz. In this context, we attempted to answer the question: How do voters judge a presidential candidate's authenticity? Here we use motivated reasoning and correspondent inference theory as theoretical frameworks to examine how partisan preference combines with perceptions of unfettered speech and strategic impression management to influence voter judgments of a candidate's authenticity. An online survey of 525 respondents demonstrated that individuals' partisan preferences influenced both judgments of a candidate's authenticity and their perceptions of behaviors signifying authenticity (use of unfettered speech versus strategic impression management). These behavioral signals partially mediated the relation between candidate preferences and authenticity judgments. Moreover, voters, given their partisan preferences, differentially weighted candidates' use of unfettered speech and strategic impression management tactics in their judgments of authenticity. Finally, unfiltered/politically incorrect speech was found to have both positive and negative effects on authenticity judgments. Findings further elucidate the nature of authenticity as perceived in others and identify intermediary variables and boundary conditions that influence those perceptions.     

Naïve and Robust: Class‐Conditional Independence in Human Classification Learning

Humans excel in categorization. Yet from a computational standpoint, learning a novel probabilistic classification task involves severe computational challenges. The present paper investigates one way to address these challenges: assuming class‐conditional independence of features. This feature independence assumption simplifies the inference problem, allows for informed inferences about novel feature combinations, and performs robustly across different statistical environments. We designed a new Bayesian classification learning model (the dependence‐independence structure and category learning model, DISC‐LM) that incorporates varying degrees of prior belief in class‐conditional independence, learns whether or not independence holds, and adapts its behavior accordingly. Theoretical results from two simulation studies demonstrate that classification behavior can appear to start simple, yet adapt effectively to unexpected task structures. Two experiments—designed using optimal experimental design principles—were conducted with human learners. Classification decisions of the majority of participants were best accounted for by a version of the model with very high initial prior belief in class‐conditional independence, before adapting to the true environmental structure. Class‐conditional independence may be a strong and useful default assumption in category learning tasks.     

Integrating Fast and Frugal Heuristics with a Model of Memory‐based Cue Generation

Although the fast and frugal heuristics have been studied extensively, relatively little attention has been paid to how cues are generated to be used within the heuristics. The goal of this paper is to propose and test a memory‐based model of how cues are generated and used in cue‐based inferences. The current study advances theory by integrating the fast and frugal heuristics with HyGene, a memory‐based model of how decision makers generate and evaluate hypotheses. Using archival data in which memory retrieval variables were not directly manipulated, we demonstrate that participants' cue selection behavior is consistent with memory‐based retrieval. Further, by directly manipulating memory retrieval within a cue‐based stock‐forecasting task, we demonstrate that memory processes underlie cue use. Participants' cue use varied depending on the relationship between cue validity and the frequency with which the cues were seen during learning. The HyGene model provided the best account of the empirical data, providing further evidence for the critical role of memory in judgment and decision making.

Positive correlation between measures of habitual responding and motivated responding in mice

Habit and motivation are thought to be separate processes, with motivated behavior often considered to be goal directed, whereas habits are defined by the absence of goal-directed control over behavior. However, there has been increasing interrogation of the binary nature of habitual versus goal-directed behavior. Furthermore, although drug and alcohol exposure can promote the formation of habits, drug seeking itself can also be highly flexible, pointing toward the need for complex consideration of the parallel processes that drive behavior. The goal of the current study was to determine whether there was a relation between motivation—as measured by progressive ratio—and habit—as measured by contingency degradation—and whether this relation was affected by ethanol exposure history and sex. The results showed that these measures were positively correlated such that greater contingency insensitivity was associated with achieving higher break points on the progressive-ratio task. However, this relation depended on reinforcement schedule history, ethanol exposure history, and sex. These point to potential relations between measures of habit and motivation and stress the importance of carefully parsing behavioral findings and assays. These findings are also expected to inform future substance use research, as drug history may affect these relations.     

Personal Goals and Depression Among Vietnamese American and European American Young Adults: A Mediational Analysis

Abstract

The authors report preliminary findings supporting the utility of the self-concordance model (K. M. Sheldon & A. J. Elliot, 1999) as an alternative approach to studying depression among Vietnamese American (N = 121) and European American (N = 155) college students. The participants completed measures of personal goals, goal self-concordance, and depression. Compared with the European American participants, the Vietnamese American participants reported higher levels of depression and lower levels of goal self-concordance. According to mediational analyses, ethnicity no longer accounted for significant variance in depression after the authors statistically controlled for goal self-concordance.     

Of BOLD Claims and Excessive Fears: A Call for Caution and Patience Regarding Political Neuroscience

Published and informal assessments of the prospects for neuroimaging in political science have tended to range from overexuberant to reflexively dismissive. We seek to present a cautious but fair middle ground in considering this new methodology, primarily from an epistemological perspective. Our examination centers on the relationship between two levels of analysis, focusing on the potential for connection between behavior‐based theories of political psychology and cognition and the neural processes and systems involved in generating behaviors and states of mind. We explore the place of each level of analysis on its own, as well as the potential for the fruitful interaction of the two. This analysis brings together opinions and ideas presented by others in various forums and across multiple disciplines, offers a discussion of the the promises and perils of neuroimaging in its application to social science, as well as some practical thoughts regarding its early‐stage incorporation into political psychology. We argue in favor of proceeding with more substantial incorporation of neuroimaging into political psychology's methodological arsenal, but note that this will initially require both (1) greater acceptance of work more focused on presenting empirical results than on providing dispositive evidence in broader theoretical debates and (2) a commitment on the part of those conducting this research to refrain from overstating the definitiveness of its theoretical implications.     

Cheapened altruism: Discounting personally affected prosocial actors

Are charitable donors always perceived as charitable? Three studies suggest that although having a personal connection to a cause motivates much charitable giving, donors who have been personally affected by the target cause are given less “credit” for their donations, i.e., are perceived as less intrinsically charitable. These donors are perceived as having selfish motivations even when they have nothing economic or social to gain from the donation. More specifically, personally-affected donors are perceived as driven by emotional selfishness, or a desire to improve their own hedonic state rather a desire to improve the welfare of others, which lessens the charitable credit that they receive. In addition, although donors who have been personally affected by the target cause are seen as less charitable, they are perceived more favorably in other ways (e.g., more loyal).
