触觉时序知觉手臂交叉效应的性别差异

本研究探讨触觉时序知觉的手臂交叉效应是否存在性别差异。通过两个实验在较短和较长的SOA条件下考察男性和女性被试在基于体觉和基于外部空间的触觉时序判断任务中的表现。结果表明,男性与女性被试在基于体觉和基于外部空间的触觉时序判断任务中均存在手臂交叉效应,SOA较短时男性被试的手臂交叉效应显著小于女性被试,但在SOA较长的条件下手臂交叉效应没有明显的性别差异。触觉时序知觉手臂交叉效应的性别差异可能与空间知觉能力和生理解剖学因素有关。

Metaphysics as interpretation of conscious life: some remarks on D. Henrich’s and D. Kolak’s thinking

In this article, I discuss the manner in which Dieter Henrich’s theory of subjectivity has emerged from the fundamental questions of German Idealism, and in what manner and to what extent this theory effects a reinstatement of metaphysics. In so doing, I shall argue that Henrich’s position represents a viable refutation of the attempt of the physicalist explanation of the world to prove the concept of the subject to be superfluous. Henrich’s metaphysics of subjectivity is primarily focused on the ‘ultimate questions’ which also compose “the deep levels of our subjectivity” and concern the factors that should promote stability in our emotional, moral and intellectual life. I argue with Henrich that the indisputable facticity of our conscious life is worthy of our special consideration and interpretation, explanation and clarification, just as the deeper meaning (the individual and collective subconscious structure) hidden beneath the layers of apparent comprehensibility calls for urgent investigation. Such interpretation and elucidation of life’s meaning has a tripartite character: first, it consists of clarification of the totality of human experience together with the realities playing a part in it; second, it builds on the process by which the contents of experience are cognized, and the knowledge thereof which results; thirdly, it embraces the transcendental precondition enabling each and every one of us to consciously lead our lives—for life, in a human sense, does not merely happen to one. Henrich’s metaphysical foundation of subjectivity is compared with Kolak‘s position, according to which individual consciousness is not insular, but integrated into the totality of overall unity that some have called “the Universal Self”, “the Noumenal Self”.     

Interactions between perinatal and neonatal associative learning defined by contiguous olfactory and tactile stimulation

Tactile stimulation of the neonate, as performed by the mother during and after delivery, has been described as an effective unconditioned stimulus during early ontogeny (Leon, 1987; Ronca & Alberts, 1994). The present experiments examined the interaction between perinatal and neonatal learning determined by the explicit association between alcohol odor and vigorous body stimulation of the perinatal organism. In Experiment 1, rat fetuses were exposed to either alcohol or saline 10 min prior to cesarean delivery. The alcohol administration procedure here employed was sufficient to provide sensory contamination of the amniotic fluid but avoid fetal alcohol intoxication. Pups in the two prenatal treatments later experienced the smell of alcohol, tactile stimulation, or both stimuli explicitly paired or unpaired. Other postnatal groups were composed of pups that had no explicit experience with either experimental stimulus. Pups subjected to alcohol odor in utero displayed more overall motor activity in response to that odor than saline controls. The increased motor responses were further potentiated in pups that experienced additional postnatal alcohol odor paired with tactile stimulation. In Experiment 2, pups were exposed to alcohol in the amniotic fluid 10 or 30 min prior to birth. As previously demonstrated the memory acquired in utero appears highly dependent upon contingency between exposure to this particular scent and delivery procedures. Pups in both prenatal treatment groups were then exposed to alcohol odor paired or unpaired with tactile stimulation. Some control animals received no further experience with either stimuli. Those pups exposed to alcohol odor paired with tactile stimulation both pre- and postnatally later showed maximum motor activity elicited by the odor of alcohol. The results support the notion of fetal associative learning comprising alcohol's chemosensory cues and behaviorally activating stimuli. Furthermore, the conditioned response under analysis is potentiated whenever neonates are reexposed to contingent presentations of the elements that defined the original associative memory.     

Experience and self-consciousness

Does all conscious experience essentially involve self-consciousness? In his Subjectivity and Selfhood: Investigating the First-Person, Dan Zahavi answers “yes”. I criticize three core arguments offered in support of this answer—a well-known regress argument, what I call the “interview argument,” and a phenomenological argument. Drawing on Sartre, I introduce a phenomenological contrast between plain experience and self-conscious experience. The contrast challenges the thesis that conscious experience entails self-consciousness.     

触觉刺激对触觉注意启动作用的研究

目的：探讨触觉刺激对触觉注意的影响,以揭示选择性注意的机制。方法：利用在体电生理记录技术,记录了288个丘脑腹侧基底核（ventrobasal nuleus of thalamus,VB）神经元放电活动,并着重考察了不同强度触觉刺激对丘脑神经元细胞自发放电活动的影响。结果发现：触觉刺激对大部分的触觉神经元的自发放电活动均有抑制性影响。提示触觉刺激降低背景噪声可能是触发选择性触觉注意的神经机制。     

Toward An Explanatory Model of Innovative Behavior

Research on innovative behavior has persistently focused on determining the correlations between numerous demographic and psychographic variables and specific external actions. Unfortunately, such research has consistently produced unreliable results. A preferred alternative to this line of research is an analysis of the causes of innovative behavior with the objective of understanding the process underlying this activity. A framework is proposed for examining innovative behavior based upon a comprehensive model of variety seeking, of which innovative behavior is one outcome. The framework attempts to depict the causes of, the processes involved, and the outcomes of variety seeking, particularly as it relates to innovative behavior. A number of propositions are presented.     

The Two-Point Threshold: Not a Measure of Tactile Spatial Resolution

The two-point threshold, or compass test, has long been used as a measure of tactile spatial resolution; however, since it was first developed, there have been problems associated with its use. Some of these problems include setting an appropriate criterion for responding "two," extreme variability both within and between subjects, and the ability of subjects to discriminate two points from one at separations well below the two-point threshold. Recent neurophysiological results have clarified some of the neural mechanisms responsible for spatial resolution and demonstrated the inadequacy of the two-point threshold as a measure of spatial mechanisms. Several new methods may overcome these problems and provide a valid measure of spatial resolution and a reflection of neural mechanisms.

Stimulus factors in the isolation-induced aggression of Bobwhite quail and Khaki Campbell ducklings

Two studies examined the relative abilities of conspecific-derived visual and tactile stimulation to modulate the occurrence of isolation-induced aggression in Bobwhite quail and Khaki Campbell ducklings. In Experiment 1, subjects were permitted visual stimulation from conspecifics but were deprived of conspecific tactile stimulation. In both species, these subjects subsequently showed significantly less aggression towards conspecifics than birds that had been deprived of both visual and tactile stimulation from conspecifics. In Experiment 2, one group of subjects was permitted conspecific tactile stimulation but was deprived of conspecific visual stimulation. Again for both species, these subjects subsequently exhibited significantly less aggressive behavior towards conspecifics than did subjects that had been both visually and tactually de-prived. In sum, the present research suggests that both tactile and visual stimulation from a conspecific are individually sufficient to reduce isolation-induced aggression in these precocial buds.
