In many literatures, scholars study summarized attribute preferences: overall evaluative summaries of an attribute (e.g., a person's liking for the attribute “attractive” in a mate). But we know little about how people form these ideas about their likes and dislikes in the first place, in part because of a dearth of paradigms that enable researchers to experimentally change people's attribute preferences. Drawing on theory and methods in covariation detection and social cognition, we developed a paradigm that examines how people infer summarized preferences for novel attributes from functional attribute preferences: the extent to which the attribute predicts an individual's evaluations across multiple targets (e.g., a person's tendency to positively evaluate mates who are more vs. less attractive). In three studies, participants encountered manipulated information about their own functional preference for a novel attribute in a set of targets. They then inferred a summarized preference for the attribute. Summarized preferences corresponded strongly to the functional preference manipulation when targets varied on only one attribute. But additional complexity (in the form of a second novel attribute) caused summarized and functional preferences to diverge, and biases emerged: Participants reported stronger summarized preferences for the attribute when the population of targets possessed more of the attribute on average (regardless of functional preference strength). We also documented some support for a standard-of-comparison mechanism to explain this inferential bias. These studies elucidate factors that may warp the translation process from people's experienced evaluative responses in the world to their overall, summary judgments about their attribute preferences.

Evaluation is central to human experience, and multiple literatures have studied it. This article pulls from research on attitudes, human and nonhuman mating preferences, consumer behavior, and beyond to build a more comprehensive framework for studying evaluation. First, we distinguish between evaluations of objects (persons, places, things) and evaluations of attributes (dimensions, traits, characteristics). Then, we further distinguish between summarized attribute preferences (a valenced response to a direction on a dimension, such as liking sweetness in desserts) and functional attribute preferences (a valenced response to increasing levels of a dimension in a set of targets, such as the extent to which sweetness predicts liking for desserts). We situate these constructs with respect to existing distinctions in the attitude literature (e.g., specific/general, indirect/direct). Finally, new models address how people translate functional into summarized preferences, as well as how attribute preferences affect (a) subsequent evaluations of objects and (b) situation selection.

It is now widely recognized that social bonds are critical to human health and well-being. One of the most important social bonds is the attachment relationship between two adults, known as the pair bond. The pair bond involves many characteristics that are inextricably linked to quality of health, including providing a secure psychological base and acting as a social buffer against stress. The majority of our knowledge about the neurobiology of pair bonding comes from studies of a socially monogamous rodent, the prairie vole (Microtus ochrogaster), and from human imaging studies, which inherently lack control. Here, we first review what is known of the neurobiology of pair bonding from humans and prairie voles. We then present a summary of the studies we have conducted in titi monkeys (Callicebus cupreus)-a species of socially monogamous New World primates. Finally, we construct a neural model based on the location of neuropeptide receptors in the titi monkey brain, as well as the location of neural changes in our imaging studies, with some basic assumptions based on the prairie vole model. In this model, we emphasize the role of visual mating stimuli as well as contributions of the dopaminergic reward system and a strong role for the lateral septum. This model represents an important step in understanding the neurobiology of social bonds in non-human primates, which will in turn facilitate a better understanding of these mechanisms in humans.
