Bedding down new words: Sleep promotes the emergence of lexical competition in visual word recognition

Lexical competition processes are widely viewed as the hallmark of visual word recognition, but little is known about the factors that promote their emergence. This study examined for the first time whether sleep may play a role in inducing these effects. A group of 27 participants learned novel written words, such as banara, at 8 am and were tested on their learning at 8 pm the same day (AM group), while 29 participants learned the words at 8 pm and were tested at 8 am the following day (PM group). Both groups were retested after 24 hours. Using a semantic categorization task, we showed that lexical competition effects, as indexed by slowed responses to existing neighbor words such as banana, emerged 12 h later in the PM group who had slept after learning but not in the AM group. After 24 h the competition effects were evident in both groups. These findings have important implications for theories of orthographic learning and broader neurobiological models of memory consolidation.     

The Perceptual Basis of Vast Space

“Vast” is a word often applied to environmental terrain that is perceived to have large spatial extent. This judgment is made even at viewing distances where traditional metric depth cues are not useful. This paper explores the perceptual basis of vast experience, including reliability and visual precursors. Experiment 1 demonstrated strong agreement in ratings of the spatial extent of two-dimensional (2D) scene images by participants in two countries under very different viewing conditions. Image categories labeled “vast” often exemplified scene attributes of ruggedness and openness (Oliva & Torralba, 2001). Experiment 2 quantitatively assessed whether these properties predict vastness. High vastness ratings were associated with highly open, or moderately open but rugged, scenes. Experiment 3 provided evidence, consistent with theory, that metric distance perception does not directly mediate the observed vastness ratings. The question remains as to how people perceive vast space when information about environmental scale is unavailable from metric depth cues or associated scene properties. We consider possible answers, including contribution from strong cues to relative depth.     

Bayesian inference with Stan: A tutorial on adding custom distributions

When evaluating cognitive models based on fits to observed data (or, really, any model that has free parameters), parameter estimation is critically important. Traditional techniques like hill climbing by minimizing or maximizing a fit statistic often result in point estimates. Bayesian approaches instead estimate parameters as posterior probability distributions, and thus naturally account for the uncertainty associated with parameter estimation; Bayesian approaches also offer powerful and principled methods for model comparison. Although software applications such as WinBUGS (Lunn, Thomas, Best, & Spiegelhalter, Statistics and Computing, 10, 325–337, 2000) and JAGS (Plummer, 2003) provide “turnkey”-style packages for Bayesian inference, they can be inefficient when dealing with models whose parameters are correlated, which is often the case for cognitive models, and they can impose significant technical barriers to adding custom distributions, which is often necessary when implementing cognitive models within a Bayesian framework. A recently developed software package called Stan (Stan Development Team, 2015) can solve both problems, as well as provide a turnkey solution to Bayesian inference. We present a tutorial on how to use Stan and how to add custom distributions to it, with an example using the linear ballistic accumulator model (Brown & Heathcote, Cognitive Psychology, 57, 153–178. doi: 10.1016/j.cogpsych.2007.12.002, 2008).     

Two Concepts of Basic Equality

It has become somewhat a commonplace in recent political philosophy to remark that all plausible political theories must share at least one fundamental premise, ‘that all humans are one another's equals’. One single concept of ‘basic equality’, therefore, is cast as the common touchstone of all contemporary political thought. This paper argues that this claim is false. Virtually all do indeed say that all humans are ‘equals’ in some basic sense. However, this is not the same sense. There are not one but (at least) two concepts of basic equality, and they reflect not a grand unity within political philosophy but a deep and striking division. I call these concepts ‘Equal Worth’ and ‘Equal Authority’. The former means that each individual’s good is of equal moral worth. The latter means that no individual is under the natural authority of anyone else. Whilst these two predicates are not in themselves logically inconsistent, I demonstrate that they are inconsistent foundation stones for political theory. A theory that starts from Equal Worth will find it near impossible to justify Equal Authority. And a theory that starts from Equal Authority will find any fact about the true worth of things, including ourselves, irrelevant to justifying legitimate action. This helps us identify the origin of many of our deepest and seemingly intractable disagreements within political philosophy, and directs our attention to the need for a clear debate about the truth and/or relationship between the two concepts. In short, my call to arms can be summed up in the demand that political philosophers never again be allowed to claim ‘that all human beings are equals’ full stop. They must be clear in what dimension they claim that we are equals—Worth or Authority (or perhaps something else).     

The Choice Architect’s Trilemma

Critics have long dismissed paternalistic choice architecture as conceptually muddled at best and oxymoronic at worst. In this article, I argue that this criticism remains true despite recent replies to the contrary. Further, I suggest that a similar conceptual criticism also applies to non-paternalistic choice architecture. This is due to a three-way tension between the effectiveness, avoidability, and distinctiveness of each nudge. To illustrate this tension, I provide a novel explanation of the mechanics of nudging and a taxonomy of these interventions. I then argue that choice architects who defend the distinctiveness of nudging according to how it guides our behaviour via our unreflective intuitive reasoning encounter a trilemma because the distinctiveness of nudging hinges on interventions being both avoidable and effective. Choice architects cannot achieve this aim without harnessing both our automatic and reflective systems of thought in tandem. However, this diminishes the distinctive character of nudging by bringing it closer to other traditional policy interventions. This establishes the choice architect’s trilemma: a nudge is likely to be either ineffective, effective via some morally unacceptable means, or effective in a manner that is conceptually indistinct from other evidence-based policy interventions.     

Still a Hetero-Gendered World: A Content Analysis of Gender Stereotypes and Romantic Ideals in Chinese Boy Love Stories

Boy’s Love (BL) stories are a fictional fantasy textual story that describes a romantic relationship between men. Previous qualitative studies claimed that BL stories have depicted androgynous characters and egalitarian love relationships. The current study undertook a quantitative content analysis of 87 randomly sampled popular Chinese BL stories. Our coding system for coding both the masculinity and femininity of each main character in the selected BL stories was developed based on several previous studies. Gay male characters in BL stories were depicted as either similar to traditional masculine men (i.e., scoring high in masculinity and low in femininity) or similar to traditional feminine women (i.e., scoring high in femininity and low in masculinity). In the romantic relationships, BL stories typically paired a masculine character with a feminine character. In addition, heterosexual romantic ideals were prevalent in BL stories. Such an analysis challenges the previous analysis of BL stories. It suggests that heteronormative gender stereotypes exist in BL stories, even if these stories depict gay male characters and romantic relationships. These findings have important implications for understanding media effects in stereotypes toward gay men in contemporary Chinese society. It also encourages further research on alternative explanations for women’s motivation in reading and writing BL stories.     

Are Men Better Leaders? An Investigation of Head Coaches’ Gender and Individual Players’ Performance in Amateur and Professional Women’s Basketball

Male-dominated industries such as sport contain stereotypical and subjective notions of leadership ability (Burton et al. 2009; Fink 2008). These gender stereotypes often manifest themselves within varying levels of leadership, but specific to the sport industry, they are the most visible within the head coach role. Men hold the majority of head coach positions within the professional and amateur levels of sport, and these hiring practices can be based on gender-role stereotypes (Acosta and Carpenter 2014). In an attempt to challenge stereotypical gender based leadership preferences, leadership ability and performance should be objectively examined. Therefore, in the present investigation we aimed to examine the presence of gender stereotypes in the sport industry by determining whether the gender of a head coach for two women’s basketball leagues, the Women’s National Basketball Association (WNBA) and the National Intercollegiate Athletic Association (NCAA), impacted individual player performance. Data were collected for 1522 players for 19 WNBA seasons (1997–2015) and 4000 players for three seasons of NCAA Women’s Basketball (2013–2016). Results indicated that head coach gender does not appear to impact individual player performance in the WNBA or in the NCAA thereby providing objective evidence to challenge the traditional gender stereotypes found within the sports industry.
