Variations in Philosophical Genre: the Platonic Dialogue

The primary function of the Platonic dialogue is not the communication of philosophical doctrines but the transformation of the reader's character. This article takes up the question of how, or by what means, the Platonic dialogue accomplishes its transformative goal. An answer is developed as follows. First, the style of reading associated with analytical philosophy is not transformative, on account of its hermeneutical attachment and epistemic equality in the relationship between reader and author. Secondly, the style of reading associated with the genre of commentary is transformative because it is governed by a principle of authority. When the commentary model is applied to the Platonic dialogue, it can be seen that the dialogue mimics the function of the authority principle in transforming the reader into a commentator, that is, someone who reads from a position of detachment and accepts responsibility for himself as moral and epistemic agent.     

Reasons,Coherence, and Group Rationality

If groups can have beliefs and other attitudes of their own, what determines which such attitudes the group rationally ought to have? A widespread presupposition is that group‐level beliefs should be a function of the beliefs of the group's members, and similarly for other attitudes. But a host of impossibility theorems show that no such aggregation function can satisfy intuitively attractive constraints while ensuring coherent group‐level attitudes. I argue that this presupposition is false. Group‐level attitudes should be a function of group‐level reasons (evidence, in the epistemic case), not individual‐level attitudes. This allows for a theory of group rationality that (i) bypasses a host of pessimistic results in the literature on judgment aggregation and (ii) treats rational individual‐level attitudes and rational group‐level attitudes in parallel.     

Naturally better? A review of the natural‐is‐better bias

People are frequently exposed to products and services that are labeled natural (e.g., Nature Made Vitamins or GoJo Natural Orange Hand Cleaner). The frequency with which this label is used suggests that it delivers an advantage in marketing and sales. Our review examines the preference for and perception of naturalness and reveals that people have a bias for items described as natural in many domains including foods, medicine, beauty products, cigarettes, and lighting. These preferences abound even when the natural item is identical or not objectively better than the non‐natural or synthetic item. We believe this bias may be driven by a natural‐is‐better default belief as well as the belief that natural items are safer than non‐natural items. Although a bias for natural items is apparent, this literature is in its infancy, and we suggest three areas that will help build and refine the empirical research base and theory: the measurement of behavior, the examination of individual differences, and the development of methods for reducing the bias. A better understanding of the naturalness bias relevant to these areas will lead to a more comprehensive understanding of the area, including factors that may cause and reduce it.     

Effect of socioeconomic status (SES) disparity on neural development in female African‐American infants at age 1 month

There is increasing interest in both the cumulative and long‐term impact of early life adversity on brain structure and function, especially as the brain is both highly vulnerable and highly adaptive during childhood. Relationships between SES and neural development have been shown in children older than age 2 years. Less is known regarding the impact of SES on neural development in children before age 2. This paper examines the effect of SES, indexed by income‐to‐needs (ITN) and maternal education, on cortical gray, deep gray, and white matter volumes in term, healthy, appropriate for gestational age, African‐American, female infants. At 5 weeks postnatal age, unsedated infants underwent MRI (3.0T Siemens Verio scanner, 32‐channel head coil). Images were segmented based on a locally constructed template. Utilizing hierarchical linear regression, SES effects on MRI volumes were examined. In this cohort of healthy African‐American female infants of varying SES, lower SES was associated with smaller cortical gray and deep gray matter volumes. These SES effects on neural outcome at such a young age build on similar studies of older children, suggesting that the biological embedding of adversity may occur very early in development.     

Development and Validation of Research Scales for the Leadership Multi‐rater Assessment of Personality (LMAP)

This article presents large‐sample developmental and validation research for a set of research scales of an existing 360‐degree personality measure, the LMAP 360 (Leadership Multi‐rater Assessment of Personality). In Study 1 (N = 1,771), we identified 6 broad domains underlying LMAP item clusters: Neuroticism, Dominance, Enthusiasm, Openness, Agreeableness, and Conscientiousness. Scales measuring these broad domains and their constituent facets showed strong internal consistency, inter‐rater reliability, and self‐informant correlations. In Study 2 (N = 729 and N = 694), we examined LMAP research scales’ convergent and discriminant validity against three well‐validated personality inventories (Goldberg's adjectives, the Big Five Inventory, and the Big Five Aspects Scales) and one measure of cognitive ability (the International Cognitive Ability Resource). LMAP research scales correlated strongly with corresponding scales from other inventories and were distinct from cognitive ability.     

A preliminary investigation on improving functional communication training by mitigating resurgence of destructive behavior

Despite the effectiveness and widespread use of functional communication training (FCT), resurgence of destructive behavior can occur if the functional communication response (FCR) contacts a challenge, such as lapses in treatment integrity. We evaluated a method to mitigate resurgence by conducting FCT using a multiple schedule of reinforcement prior to extinction. After functional analyses of 2 boys’ destructive behavior and treatment with FCT (Study 1), we compared levels of resurgence during an extinction challenge either after a typical FCT sequence or after exposure to schedule thinning in the context of a multiple‐schedule arrangement (Study 2). Results for both participants suggested that schedule thinning using discriminative stimuli in a multiple schedule mitigated the resurgence of destructive behavior.     

How surveillance begets perceptions of dishonesty: the case of the counterfactual sinner

Three studies support the hypothesis that observers' impressions of actors reflect not only what actors do but also what they can easily be imagined doing. Participants in Studies 1 and 2 observed a 10-year-old boy take a math test in a context in which the incentive to cheat and the constraints against cheating varied. When the incentive to cheat was high but the likelihood of getting caught was also high, observers perceived a target who resisted the temptation to cheat as less honest than the average boy. This effect was not found when the incentive to cheat was low, which suggests that its occurrence under high temptation resulted from observers in that condition generating the counterfactual thought that the target would have cheated had the likelihood of detection been low. Study 3 further supported the link between spontaneous counterfactual thought and inferences of dishonesty. The implications of the counterfactual correspondence bias are discussed.
