康德遗著——遗世手稿、康德的工作方式和遗稿新编

康德的《遗著》包含着康德的从自然的理性形而上学向经验科学过渡的未完成的哲学计划,《康德全集》中原有的非批判的版本存在着诸多欠缺,因此新的版面采用发生学的结构分析,通过对康德的工作方式的考察,重现了康德的凌乱而又被密集书写的手稿上的文字产生的时间顺序和逻辑关系,从而最大限度地还原了康德对这一问题的整个思考过程。     

Neural enhancement and pre-emptive perception: the genesis of attention and the attentional maintenance of the cortical salience map

One of the stable hypotheses in systems neuroscience is the relationship between attention and the enhancement of visual responses when an animal attends to the stimulus in its receptive field (Goldberg and Wurtz, 1972 Journal of Neurophysiology 35 560-574). This was first discovered in the superior colliculus of the monkey: neurons in the superficial layers of the superior colliculus responded more intensely to the onset of a stimulus during blocks of trials in which the monkey had to make a saccade to it than they did during blocks of trials in which the monkey had to continue fixating a central point and not respond to the stimulus. This enhancement has been found in many brain regions, including prefrontal cortex (Boch and Goldberg, 1987 Investigative Ophthalmology 28 Supplement, 124), V4 (Moran and Desimone, 1985 Science 229 782-784), and lateral intraparietal area (Colby et al, 1996 Journal of Neurophysiology 76 2841-2852; Colby and Goldberg, 1999 Annual Review of Neuroscience 22 319-349), and even V1 (Lamme et al, 2000 Vision Research 40 1507-1521). In these studies the assumption has been that the monkey attended to the stimulus because the stimulus evoked an enhanced response. In the experiments described here we show that for abruptly appearing stimuli, attention is not related to the initial response evoked by the stimulus, but by the activity present on the salience map in the parietal cortex when the stimulus appears. Attention to the stimulus may subsequently, by a top down signal, sustain the map, but stimuli can as easily be suppressed by top down features as they can be enhanced.     

Intersectional Identities and the Politics of Altruistic Care in a Low-Income, Urban Community

The literatures on the ways in which social identity and social position (e.g., gender, class, race) inform altruism have developed orthogonally. In this community-based qualitative study we use intersectionality theory to explore the complex ways in which social identity and social structures jointly influence altruism among African American adults (n?=?40) in an urban, economically distressed housing community in New York City. Content analysis of participants’ narratives reveals the ways in which gender, race, ethnicity, class, age, and urbanicity work in tandem to create differential patterns of vulnerability, differential needs, differential commitments to caring for particular subgroups, and informs how altruists are perceived by others. The implications of this work for future research on altruism are highlighted.     

"Just looking at food makes me gain weight": experimental induction of thought-shape fusion in eating-disordered and non-eating-disordered women

Thought-shape fusion (TSF) is a cognitive distortion that can be induced experimentally and is associated with eating pathology. The current study was conducted in order to elucidate the effects of TSF induction in females with eating disorders (n=35), as well as in restrained eaters (n=38) and unrestrained eaters (n=39). It was hypothesized that TSF induction would result in anxiety, guilt, increased feelings of fatness, perceived weight gain and feelings of moral wrong-doing relative to an anxiety and control induction. It was further hypothesized that restrained eaters and individuals with eating disorders would exhibit a stronger reaction to a TSF induction than would unrestrained eaters. The results indicated that, as predicted, TSF can be induced in individuals both with and without eating disorders, and individuals with eating disorders reported the highest levels of "state" TSF after the induction relative to the non-clinical controls. However, contrary to expectations, restrained eaters reported higher levels of perceived weight gain and moral wrong-doing after the anxiety induction (but not the TSF induction) relative to the control induction. Potential mechanisms for this pattern of results are discussed, and the clinical implications of research on TSF are also considered.     

Pathways to suicidal behaviors in childhood

Path analyses were applied to test a model that includes internalizing and externalizing behavior problems as predictors of suicidal behaviors in children. Parents of an inpatient sample of boys (N=87; M age=9.81 years) rated the frequency of suicidal ideation and completed standardized measures of behavior problems. Blind raters rated the severity of the children's suicidal behaviors. Results revealed a significant direct effect for suicidal ideation on suicide attempt and for depressive symptoms on suicidal ideation. There was also a significant indirect path from impulsivity to suicidal ideation through aggressive and depressive symptoms. Clinical implications are discussed.
