What If? The Farther Shores of Neuroethics

Neuroscience is clearly making enormous progress toward understanding how human brains work. The implications of this progress for ethics, law, society, and culture are much less clear. Some have argued that neuroscience will lead to vast changes, superseding much of law and ethics. The likely limits to the explanatory power of neuroscience argue against that position, as do the limits to the social relevance of what neuroscience will be able to explain. At the same time neuroscience is likely to change societies through increasing their abilities to predict future behavior, to infer subjective mental states by observing physical brain states (??read minds??), to provide evidence in some cases relevant to criminal responsibility, to provide new ways to intervene to ??treat antisocial brains,?? and to enhance healthy brains. Neuroscience should make important cultural changes in our special, and specially negative, views of ??mental?? versus ??physical?? illness by showing that mental illness is a dysfunction of a physical organ. It will not likely change our beliefs, implicit or explicit, in free will, or spark a new conflict between science and religion akin to the creationism controversy.     

Statelessness and the Politics of Misrecognition

This article focuses on the account of disrespect found in Honneth’s theory of recognition. In it, I am particularly interested in the form of misrecognition or disrespect which is the negation of respect, and which is clearly represented by statelessness. Respect, for Honneth, is closely connected to legal recognition. Guided by Honneth’s view of critical theory as ‘not entirely without a foundation in social reality’, the article puts together an analysis of the political dynamics of his model of disrespect. This analysis is used to challenge certain aspects of Honneth’s political theory and in particular the implications of his conception of the state. The article argues that the way in which the state is used has the effect of obscuring significant political obstacles to recognition, and in particular, the way in which the state limits respect.     

Curriculum tracking and teacher expectations: evidence from discrepant course taking models

In an effort to understand teacher-student relationships much research has investigated how teacher expectations of student performance in the classroom affect achievement growth. However, little research has focused on how teacher expectations of students?? educational attainment are formed. In this paper, we examine how students?? high school track placements affect teacher expectations regarding students?? educational attainment in the NELS data. NELS is a large, nationally representative longitudinal study from the United States of the graduating class of 1992. We focus on students with discrepant track placements to determine how different teachers evaluate the same student. Overall, for the same student, teachers in high track classes have higher college expectations than teachers in lower track classrooms.     

Neural correlates of automatic mood regulation in girls at high risk for depression

Daughters of depressed mothers are at significantly elevated risk for developing a depressive disorder themselves. We have little understanding, however, of the specific factors that contribute to this risk. The ability to regulate negative affect effectively is critical to emotional and physical health and may play an important role in influencing risk for depression. We examined whether never-disordered daughters whose mothers have experienced recurrent episodes of depression during their daughters' lifetime differ from never-disordered daughters of never-disordered mothers in their patterns of neural activation during a negative mood induction and during automatic mood regulation. Sad mood was induced in daughters through the use of film clips; daughters then recalled positive autobiographical memories, a procedure shown previously to repair negative affect. During the mood induction, high-risk girls exhibited greater activation than did low-risk daughters in brain areas that have frequently been implicated in the experience of negative affect, including the amygdala and ventrolateral prefrontal cortex. In contrast, during automatic mood regulation, low-risk daughters exhibited greater activation than did their high-risk counterparts in brain areas that have frequently been associated with top-down regulation of emotion, including the dorsolateral prefrontal cortex and dorsal anterior cingulate cortex. These findings indicate that girls at high and low risk for depression differ in their patterns of neural activation both while experiencing, and while repairing negative affect, and suggest that anomalies in neural functioning precede the onset of a depressive episode.     

Interpreting and reacting to feedback in stereotype-relevant performance domains

Feedback on task performance is often phrased in subjective language (e.g., “not bad!”), but how do recipients understand or translate that feedback into a clear, objective, performance metric? We suggest that when feedback is provided in a stereotype-relevant domain, translation is made with reference to stereotyped expectations for one's group. In Study 1, women and men were exposed to negative subjective feedback about their performance on a leadership task; in Study 2, Black and White participants were provided subjective negative feedback, or no feedback, on an academic writing task. Women relative to men, and Black students relative to White students, translated their feedback to indicate objectively worse performance. Furthermore, this translation mediated a drop in the importance placed on the domain among women and Blacks. This research extends the literature on gender- and race-based reactions to feedback by noting the importance of the immediate interpretation of the feedback received.     

The “pure-study” learning curve: The learning curve without cumulative testing

The customary assumption in the study of human learning using alternating study and test trials is that learning occurs during study trials and that test trials are useful only to measure learning. In fact, tests seem to play little role in the development of learning, because the learning curve is similar even when the number of test trials varies widely (Tulving, Journal of Verbal Learning and Verbal Behavior 6:175-184, 1967). However, this outcome seems odd, because other research has shown that testing fosters greater long-term learning than does studying. We report three experiments addressing whether tests affect the shape of the learning curve. In two of the experiments, we examined this issue by varying the number of spaced study trials in a sequence and examining performance on only a single test trial at the end of the series (a "pure-study" learning curve). We compared these pure-study learning curves to standard learning curves and found that the standard curves increase more rapidly and reach a higher level in both free recall (Exp. 1) and paired-associate learning (Exp. 2). In Experiment 3, we provided additional study trials in the "pure-study" condition to determine whether the standard (study-test) condition would prove superior to a study-study condition. The standard condition still produced better retention on both immediate and delayed tests. Our experiments show that test trials play an important role in the development of learning using both free-recall (Exps. 1 and 3) and paired-associate (Exp. 2) procedures. Theories of learning have emphasized processes that occur during study, but our results show that processes engaged during tests are also critical.     

Further routes to psychological constructionism

In this commentary, we do two things. First, we sketch two further routes to psychological constructionism. They are complementary to Lindquist et al.'s meta-analyses and have potential to add new evidence. Second, we look at a challenging kind of case for constructionism, namely, emotional anomalies where there are correlated, and probably relevant, brain anomalies. Psychopaths are our example.     

Beyond Iraq and Afghanistan: Religion and Politics in United States War‐Culture

Abstract : This article digs beneath the surface of American assumptions regarding war to explore the ethical interconnections between national identity, war, and religion. Striking differences emerge between the dynamics of religion and politics with regard to war and peace in presidential speeches regarding the Iraq and Afghanistan wars, and the analysis of war from an earlier generation, encapsulated by Dr. Martin Luther King Jr.'s “Beyond Vietnam: A Call to Conscience,” from 1967. Study of this political discourse helps us better understand our own reality in the United States, and the moral consequences of our beliefs about war, sacrifice, the human character, and the identity of the nation.     

Dividing attention lowers children's but increases adults' false memories

The present study examined the impact of divided attention on children's and adults' neutral and negative true and false memories in a standard Deese/Roediger-McDermott paradigm. Children (7- and 11-year-olds; n = 126) and adults (n = 52) received 5 neutral and 5 negative Deese/Roediger-McDermott word lists; half of each group also received a divided attention task. The results showed that divided attention affected children's and adults' false memory levels differently but did not alter true memory differently. Our results revealed a developmental shift in that divided attention lowered children's false memory rates but increased adults' false memory rates, regardless of the nature of the material (i.e., neutral or negative). Our study indicates that manipulations that target conscious processing (e.g., divided attention) result in marked qualitative and quantitative differences between children's and adults' false memories but not true memories.
