Shifty talk: knowledge and causation

In this paper, I criticise one main strategy for supporting anti-intellectualism, the view that whether a subject knows may depend on the stakes. This strategy appeals to difficulties with developing contextualist and pragmatic treatments of the shiftiness of our talk about knowledge to motivate anti-intellectualism. I criticise this strategy by drawing an analogy between debates about causation and knowledge. In each case, talk about a phenomenon is shifty and contextualist and pragmatic explanations of the shifty talk face the same objections. However, in the case of causation it would be implausible to argue that difficulties with the relevant contextualist and pragmatic accounts motivate a revisionary metaphysics of causation. I conclude that the defender of anti-intellectualism needs to employ a different strategy to defend her view.     

The Priority Principle from Kant to Frege

In a famous passage (A68/B93), Kant writes that “the understanding can make no other use of […] concepts than that of judging by means of them.” Kant's thought is often called the thesis of the priority of judgments over concepts. We find a similar sounding priority thesis in Frege: “it is one of the most important differences between my mode of interpretation and the Boolean mode […] that I do not proceed from concepts, but from judgments.” Many interpreters have thought that Frege's priority principle is close to (or at least derivable from) Kant's. I argue that it is not. Nevertheless, there was a gradual historical development that began with Kant's priority thesis and culminated in Frege's new logic.     

Religious Schools,Home Schools,and the Timing of First Marriage and First Birth

The timing of individuals’ family formation is important for a number of socioeconomic and health outcomes. We examine the influence of religious schools and home schools on the timing of first marriage and first birth using data from the Cardus Education Study Graduate Survey (N = 1,496). Our results from life tables and event-history regression models show that, on average, graduates of evangelical Protestant schools—but not Catholic school or homeschool graduates—have earlier marriages and births than public school graduates. Catholic school students have later first births on average than public school graduates. Models interacting schooling type with age and age-squared suggest that evangelical schoolers’ higher odds of marriage stem from higher odds of marrying at ages 21–30, and their higher odds of first birth stem from higher odds of births from ages 25–34. Catholic school and nonreligious private school students also have higher odds of marrying in the mid-20s and early-30s than do public school students. Evangelical, non-religious private, and Catholic school students all have lower odds of teenage births than public school students but higher odds of birth later in the life course. Homeschoolers do not differ on either outcome at any age. Our findings suggest that schools socialize their students with distinctive attitudes toward family formation that influence their behavior even many years after graduation, though these schools do not appear to be particularly harmful to life chances in terms of fostering marriage or childbearing at very young ages.     

Memory search for the first target modulates the magnitude of the attentional blink

The resolution of temporal attention is limited in a manner that makes it difficult to identify two targets in short succession. This limitation produces the phenomenon known as the attentional blink (AB), in which processing of a first target (T1) impairs identification of a second target (T2). In the AB literature, there is broad agreement that increasing the time it takes to process T1 leads to a larger AB. One might, therefore, predict that increasing the number of possible T1 identities, or target set, from 1 to 16 would lead to a larger AB. We were surprised to find that this manipulation of T1 difficulty had no influence on AB magnitude. In subsequent experiments, we found that AB magnitude interacts with T1 processing time only under certain circumstances. Specifically, when the T1 task was either well masked or had to be completed online, we found a reliable interaction between AB magnitude and the target set size. When neither of these conditions was fulfilled, there was no interaction between target set size and the AB. Previous research found that when the target set changes from trial to trial, trials with more possible targets elicited a larger AB. In the present study, the target set is held constant, reducing the demands on working memory. Nevertheless, AB magnitude still interacts with target set size, as long as the T1 task cannot be processed offline. Thus, the act of searching memory delays subsequent processing, even when the role of working memory has been minimized.     

The Impact of Feminist Attitudes on the Relation between Racial Awareness and Racial Identity

This study examined the role of liberal and inclusive feminist attitudes in the development of a positive racial identity in a sample of White female undergraduates in the Midwestern United States. Participants (N?=?90) provided self-report data on their racial awareness, liberal and inclusive feminist attitudes, racial identity and demographic information. The main research question was how and to what extent liberal and inclusive feminism influence the relationship between racial awareness and racial identity. Building on conceptual scholarship on identity theory and the intersectionality, results indicated that the relation between racial awareness and racial identity was partially mediated by inclusive feminist attitudes but not by liberal feminist attitudes. The results suggest that a specific type of feminism, which takes into account the experience of race, plays a significant role in our understanding of how White women develop a positive White identity. Results highlight the intersection of race and gender in college student development and have potential implications for administrative responses to student adjustment in increasingly diverse college environments.     

The Impact of a Digital Recorder Intervention in Pragmatic/Experiential Therapy for Couples: A Pilot Study to Assess Emotional Flooding

The present study explored the effectiveness of a unique intervention for couple therapy, the Canned Attitude Method (a technique developed by Brent Atkinson), which utilized a digital recorder in and between therapy sessions. Participant dyads were randomly assigned to the intervention group utilizing the digital recorders or the control group, in which Pragmatic/Experiential Therapy for Couples (Atkinson in J Syst Ther 17:18–35, 1998) was conducted without the use of digital recorders. Both the intervention and the control groups were composed of five couples each for a total of 20 participants. This study hypothesized that the use of the Canned Attitude Method in couple therapy would produce a significant change in marital satisfaction, emotional flooding, and positive psychological tendencies associated with intimate relationships. Findings approached significance, demonstrating decreases in the experience of emotional flooding, gains in relationship satisfaction, and a shift towards positive attributes within the couples’ relationships.     

Perfectionism as a Predictor of Post-event Rumination in a Socially Anxious Sample

Socially anxious individuals tend to have elevated levels of perfectionism and engage in excessive rumination following social situations. The present research aimed to examine perfectionism, in both state and trait forms, as a predictor of post-event rumination. Socially anxious students (N = 104) completed measures of trait perfectionism prior to, and state perfectionism following, an anxiety inducing speech task. Post-event rumination was assessed 2 days later. State and trait perfectionism were significant predictors of post-event rumination (2 days later), while controlling for baseline social anxiety, depression and state anxiety. These results support the need to target perfectionism in treatments for social anxiety disorder.     

Reduced susceptibility to confirmation bias in schizophrenia

Patients with schizophrenia (SZ) show cognitive impairments on a wide range of tasks, with clear deficiencies in tasks reliant on prefrontal cortex function and less consistently observed impairments in tasks recruiting the striatum. This study leverages tasks hypothesized to differentially recruit these neural structures to assess relative deficiencies of each. Forty-eight patients and 38 controls completed two reinforcement learning tasks hypothesized to interrogate prefrontal and striatal functions and their interaction. In each task, participants learned reward discriminations by trial and error and were tested on novel stimulus combinations to assess learned values. In the task putatively assessing fronto-striatal interaction, participants were (inaccurately) instructed that one of the stimuli was valuable. Consistent with prior reports and a model of confirmation bias, this manipulation resulted in overvaluation of the instructed stimulus after its true value had been experienced. Patients showed less susceptibility to this confirmation bias effect than did controls. In the choice bias task hypothesized to more purely assess striatal function, biases in endogenously and exogenously chosen actions were assessed. No group differences were observed. In the subset of participants who showed learning in both tasks, larger group differences were observed in the confirmation bias task than in the choice bias task. In the confirmation bias task, patients also showed impairment in the task conditions with no prior instruction. This deficit was most readily observed on the most deterministic discriminations. Taken together, these results suggest impairments in fronto-striatal interaction in SZ, rather than in striatal function per se.
