Saving the worst for last: The effect of time horizon on the efficiency of negotiating benefits and burdens

Three experiments explored the effect of outcome delays—longer time horizons for the realization of outcomes—on the efficiency of negotiated agreements. We hypothesized that there would be a positive relationship between a longer temporal distance to the consequences of negotiated agreements and the efficiency of those agreements. Outcome delays did increase the efficiency of the negotiated agreements. In addition, type of resource, burden or benefit, moderated this relationship. Because negotiating for burdens is more difficult than negotiating for benefits in the present, the salutary discounting effects of outcome delays were greater for burdens. The multifaceted effects of time on negotiations are discussed.     

Inequity/Iniquity: Card on Balancing Injustice and Evil

Card argues that we should not give injustice priority over evil. I agree. But I think Card sets us up for some difficult balances, for example of small evils against middle‐sized injustices. I suggest some ways of staying off the tightrope.     

Modulation of cognitive flexibility by hunger and desire

Knowing when to persevere with a plan and knowing when to ditch it and change strategy is highly adaptive and breaks down in several frontal and striatal disorders. Cognitive flexibility is also susceptible to tonic influences of neuromodulators (such as dopamine) and so may be influenced by everyday fluctuations in processes known to depend upon them (such as motivation). The current study employed an attentional shifting paradigm to examine the influence of changes in food-related motivational state in healthy volunteers. Hunger was induced through fasting (physiological manipulation) or through the presentation of appetitive food cues prior to testing (desire manipulation). The desire manipulation produced a stronger effect than fasting by inducing errors when participants were attempting to shift. The results suggest that everyday fluctuations in appetite and desire can produce a significant impact on cognition, highlighting implications for our understanding of excessive motivational control including maladaptive eating behaviour.     

(ANTI)‐Anti‐Intellectualism and the Sufficiency Thesis

Anti‐intellectualists about knowledge‐how insist that, when an agent S knows how to φ, it is in virtue of some ability, rather than in virtue of any propositional attitudpaes, S has. Recently, a popular strategy for attacking the anti‐intellectualist position proceeds by appealing to cases where an agent is claimed to possess a reliable ability to φ while nonetheless intuitively lacking knowledge‐how to φ. John Bengson and Marc Moffett and Carlotta Pavese have embraced precisely this strategy and have thus claimed, for different reasons, that anti‐intellectualism is defective on the grounds that possessing the ability to φ is not sufficient for knowing how to φ. We investigate this strategy of argument‐by‐counterexample to the anti‐intellectualist's sufficiency thesis and show that, at the end of the day, anti‐intellectualism remains unscathed.     

Why Higher Working Memory Capacity May Help You Learn: Sampling,Search, and Degrees of Approximation

Algorithms for approximate Bayesian inference, such as those based on sampling (i.e., Monte Carlo methods), provide a natural source of models of how people may deal with uncertainty with limited cognitive resources. Here, we consider the idea that individual differences in working memory capacity (WMC) may be usefully modeled in terms of the number of samples, or “particles,” available to perform inference. To test this idea, we focus on two recent experiments that report positive associations between WMC and two distinct aspects of categorization performance: the ability to learn novel categories, and the ability to switch between different categorization strategies (“knowledge restructuring”). In favor of the idea of modeling WMC as a number of particles, we show that a single model can reproduce both experimental results by varying the number of particles—increasing the number of particles leads to both faster category learning and improved strategy‐switching. Furthermore, when we fit the model to individual participants, we found a positive association between WMC and best‐fit number of particles for strategy switching. However, no association between WMC and best‐fit number of particles was found for category learning. These results are discussed in the context of the general challenge of disentangling the contributions of different potential sources of behavioral variability.     

From Self‐Respect to Respect for Others

The leading accounts of respect for others usually assume that persons have a rational nature, which is a marvelous thing, so they should be respected like other objects of ‘awesome’ value. Kant's views about the ‘value’ of humanity, which have inspired contemporary discussions of respect, have been interpreted in this way. I propose an alternative interpretation in which Kant proceeds from our own rational self‐regard, through our willingness to reciprocate with others, to duties of respect for others. This strategy, which shares some similarities with moral contractualism, offers a way to justify other‐regarding moral requirements from self‐regarding rational dispositions.     

A DUAL-IDENTITY FRAMEWORK FOR UNDERSTANDING LESBIAN EXPERIENCE

The diverse life experiences of contemporary lesbians are shaped by women's differing ties to two social worlds, the majority heterosexual society and the minority subculture of the lesbian or sexual-minority world. This article presents a detailed conceptual analysis of a dual-identity framework that emphasizes lesbians' simultaneous affiliations with both lesbian and mainstream/heterosexual communities. The usefulness of this approach is discussed, with emphasis on implications for understanding individual differences in exposure to gay-related stress and mental health. Results from a survey of 116 lesbians showed that scores on measures of Lesbian Identity and Mainstream Identity were not significantly correlated with each other. Both lesbian and mainstream identities were significantly related to lesbians' reported experiences of discrimination, feelings of internalized homophobia, and life satisfaction. Limitations of the dual-identity framework and suggestions for future research are considered.
