Sensations as Representations in Kant

This paper defends an interpretation of the representational function of sensation in Kant's theory of empirical cognition. Against those who argue that sensations are ‘subjective representations’ and hence can only represent the sensory state of the subject, I argue that Kant appeals to different notions of subjectivity, and that the subjectivity of sensations is consistent with sensations representing external, spatial objects. Against those who claim that sensations cannot be representational at all, because sensations are not cognitively sophisticated enough to possess intentionality, I argue that Kant does not use the term ‘Vorstellung’ to refer to intentional mental states exclusively. Sensations do not possess their own intentionality, but they nevertheless perform a representational function in virtue of their role as the matter of empirical intuition. In empirical intuition, the sensory qualities given in sensation are combined with the representation of space to constitute the intuited appearance. The representational function of sensation consists in sensation being the medium out of which intuited appearances are constituted: the qualities of sensations stand in for what the understanding will judge (conceptualize) as material substance.     

中小学生感觉寻求量表的编制与应用

通过文献分析和实证研究,构建了中小学生感觉寻求的理论维度,并据此编制了中小学生感觉寻求的测量量表。以14,560名中小学生为有效被试,对量表进行了探索性因素分析和验证性因素分析后表明:中小学生感觉寻求包含两个维度,即兴奋与冒险寻求、去抑制,所构建的中小学生感觉寻求理论体系比较合理,中小学生感觉寻求量表具有较好的信度和效度,可以作为中小学生感觉寻求研究的测量工具。我国中小学生感觉寻求特点同国外研究结果表现出大体相同趋势。兴奋与冒险寻求、去抑制,以及综合感觉寻求水平,男生均显著高于女生。从年级发展趋势看,中小学生感觉寻求水平总体上逐年增高。     

父母控制、不良同伴和感觉寻求对工读生毒品使用的影响机制

在社会学习理论和生态系统理论基础上提出一个有调节的中介模型,探讨父母心理控制、行为控制与工读生毒品使用的关系,以及结交不良同伴的中介效应和感觉寻求的调节效应。514名工读生完成了父母控制问卷、不良同伴问卷、感觉寻求量表和毒品使用问卷。结果显示:(1)父母心理控制能正向预测工读生的毒品使用,父母行为控制能负向预测工读生的毒品使用。(2)结交不良同伴在心理控制、行为控制与工读生毒品使用的关系中起中介作用。(3)结交不良同伴的中介作用受到感觉寻求的调节。

ENSEMBLE RECORDINGS IN AWAKE RATS: ACHIEVING BEHAVIORAL REGULARITY DURING MULTIMODAL STIMULUS PROCESSING AND DISCRIMINATIVE LEARNING

To meet an increasing need to examine the neurophysiological underpinnings of behavior in rats, we developed a behavioral system for studying sensory processing, attention and discrimination learning in rats while recording firing patterns of neurons in one or more brain areas of interest. Because neuronal activity is sensitive to variations in behavior which may confound the identification of neural correlates, a specific aim of the study was to allow rats to sample sensory stimuli under conditions of strong behavioral regularity. Our behavioral system allows multimodal stimulus presentation and is coupled to modules for delivering reinforcement, simultaneous monitoring of behavior and recording of ensembles of well isolated single neurons. Using training protocols for simple and compound discrimination, we validated the behavioral system with a group of 4 rats. Within these tasks, a majority of medial prefrontal neurons showed significant firing‐rate changes correlated to one or more trial events that could not be explained from significant variation in head position. Thus, ensemble recordings can be combined with discriminative learning tasks under conditions of strong behavioral regularity.     

Imagery and olfactory stimulation

The purpose of the present study was to investigate a possible odor-emotion interaction by determining whether humans could differentially detect other humans' odor collected under varying emotional conditions. Odorants were collected from the axillary apocrine glands of four female donors, each of whom underwent different imagery induction procedures of anxiety, relaxation, and sexual arousal. The odorants were chemically preserved and later evaluated by 16 naive white male judges as to the presence of discriminatory odor cues. Judges' imagery was differentially related to the anxiety imagery-produced odorants but only for those produced by the most imaginative donors. The relaxation odorants of all donors were correlated. The judges were unable to detect the sexual imagery arousal odorants.     

Associations between volume of alcohol consumption and social status, intelligence, and personality in a sample of young adult Danes

Relatively few studies have investigated associations between volume of alcohol consumption and psychological characteristics in normal samples. A sub-sample, comprising 363 men and 331 women between 29 and 34 years of age, was selected from the Copenhagen Perinatal Cohort on the basis of perinatal records. The sample was divided into four consumption categories: abstainers (including occasional drinkers), light, moderate, and risk drinkers. ANOVA and relevant contrasts were used to test the significance of differences among consumption categories. Both abstaining and risk drinking were associated with low social status family background, low education and intelligence. Abstaining was associated with low disinhibition and social recognition scores, while risk drinking was associated with high neuroticism and, in males, high disinhibition, low social recognition, and low achievement scores. Compared with light drinkers, a more "carefree" life orientation characterized male moderate drinkers, while relatively high scores on anxiety, dysthymia, and somatoform symptom scales characterized female moderate drinkers.     

Unique characteristics of neonatal classical conditioning: The role of the amygdala and locus coeruleus

The central nervous system of altricial infants is specialized for optimizing attachments to their caregiver. During the first postnatal days, infant rats show a sensitive period for learning and particularly susceptible to learning an attraction to their mother’s odor. Classical conditioning appears to underlie this learning that is expressed behaviorally as anincreased ability to acquire odor preferences and a decreased ability to acquire odor aversions. Specifically, in neonatal rats, pairing an odor with moderately painful shock (0.5mA) or milk produces a subsequent relativepreference for that odor. The neural circuitry supporting theincreased ability to acquire odor preferences appears to be the heightened functioning of the noradrenergic pontine nucleus locus coeruleus. Indeed, norepinephrine from the locus coeruleus appears to be both necessary and sufficient for learning during the sensitive period. On the other hand, thedecreased ability to acquire odor aversions seems to be due to the lack of participation of the amygdala in at least some aversive learning situations. The site of plasticity in the pup’s brain appears to be limited to the olfactory bulb. This neonatal sensitive period for learning ends around postnatal day 9–10, at which time pups make the transition from crawling to walking and classical conditioning becomes “adultlike”. The neonatal behavioral and neural induced changes are retained into adulthood where it modifies sexual behavior.     

Sexuality and the drive for muscularity: Evidence of associations among British men

Previous studies have documented associations between sexuality and body image, but the directionality of this association is unclear among men. This study examined whether men's drive for muscularity can be considered a correlate of their sexuality. A community-based sample of 292 heterosexual men from London, UK, completed a survey consisting of measures of drive for muscularity, sociosexuality, sexual assertiveness, sexual esteem, and sexual sensation seeking. A multiple regression analysis showed that greater drive for muscularity was predicted by more unrestricted sociosexuality (i.e., a greater proclivity for short-term, transient relationships), greater sexual sensation seeking, and greater sexual assertiveness, once the effects of participant age and body mass index had been accounted for. Possible avenues for intervention based on a sex-positive approach are discussed in conclusion.     

Embodied involvement in virtual worlds: the case of eSports practitioners

Abstract

eSports practice designates a unique set of activities tethered to competitive, virtual environments, or worlds. This correlation between eSports practitioner and virtual world, we argue, is inadequately accounted for solely in terms of something physical or intellectual. Instead, we favor a perspective on eSports practice to be analyzed as a perceptual and embodied phenomenon. In this article, we present the phenomenological approach and focus on the embodied sensations of eSports practitioners as they cope with and perceive within their virtual worlds. By approaching eSports phenomenologically, we uncover ways in which its unique forms of virtual involvement overlap with as well as differentiate themselves from traditional structures of embodiment.
