Minority influence: the role of ambivalence toward the source

According to literature on social influence, a minority source may indirectly influence group members by fostering ambivalent reactions. Two studies were carried out in order to provide empirical support for this theoretical assumption. In Study 1 participants (n = 133), were exposed to a counter‐attitudinal minority message and ambivalence was manipulated by facilitating the accessibility of either ambivalent (positive and negative) or univalent (positive or negative) thoughts toward the source. We predicted and found more indirect influence in ambivalent condition than in univalent conditions. No effect of ambivalence on direct influence was found. In Study 2 (n = 127), ambivalence was measured and two possible antecedents of ambivalence, consistency of the minority and personal relevance of the topic for participants, were taken into account. Findings suggest that ambivalence mediates the effects of the two factors on indirect influence. In sum, these studies provide evidence of the importance of ambivalence in minority influence context, an early assumption that was still lacking in strong empirical support.

Effect of compatibility of S-R mapping on reactions toward the stimulus source

This research was concerned with separating the effects of three varieties of S-R compatibility: reactions toward the stimulus source, compatibility of S-R mapping, and display-control arrangement correspondence. In experiments 1 and 2, subjects pressed a green or red key located on the left and right in response to the onset of a green or red stimulus presented in a left or right window. Half of the subjects pressed the key which corresponded to the color of the stimulus (compatible S-R mapping) while the other half pressed the alternate colored key (incompatible S-R mapping). In the compatible mapping task, reactions were faster when location of stimulus and response corresponded than when they did not while, in the incompatible task, reactions were faster when location of stimulus and response did not correspond. This apparent reversal in the tendency to react toward the stimulus source was attributed to display- control arrangement correspondence rather than to logical recoding of the directional cue. Experiment 3 established that faster reactions toward the stimulus source occured only under compatible mapping instructions.     

Foraging for brain stimulation: toward a neurobiology of computation

The self-stimulating rat performs foraging tasks mediated by simple computations that use interreward intervals and subjective reward magnitudes to determine stay durations. This is a simplified preparation in which to study the neurobiology of the elementary computational operations that make cognition possible, because the neural signal specifying the value of a computationally relevant variable is produced by direct electrical stimulation of a neural pathway. Newly developed measurement methods yield functions relating the subjective reward magnitude to the parameters of the neural signal. These measurements also show that the decision process that governs foraging behavior divides the subjective reward magnitude by the most recent interreward interval to determine the preferability of an option (a foraging patch). The decision process sets the parameters that determine stay durations (durations of visits to foraging patches) so that the ratios of the stay durations match the ratios of the preferabilities.     

对由不同途径感染的艾滋病患者的区别性反应及中介分析

研究探讨了中国大学生对由不同途径感染的艾滋病患者的区别性反应,涉及的因变量包括对艾滋病患者的总体感受、情绪反应、责任感知、接触意愿等。结果显示：1）和主观不可控途径（输血和母婴）相比,大学生对由可控途径（性和吸毒）感染的艾滋病患者感到更多的生气、讨厌和恐惧,更少地感到同情,表现出更强的负性态度,更少的接触意愿;同时还认为由性和吸毒感染的艾滋病患者应该承担更多的责任,更应该接受强制处理;2）女性比男性表现出对艾滋病患者更低的接触意愿,但是在其它反应上,均没发现性别差异;3)中介分析显示,对由不同途径感染的艾滋病患者的不同的态度反应在一定程度上是由不同的情绪反应导致的,负性情绪会导致负性态度,同情会导致正性态度。这些结果提示,要减少对艾滋病患者的偏见和歧视等负性反应,营造一个有利于艾滋病防治的社会环境,对由不同途径感染的艾滋病患者应该有针对性地采取不同的策略,要尽可能减少负性情绪、唤起同情心     

Government policy toward open source software: The puzzles of neutrality and competition

For a variety of policy reasons, governments throughout the world are now adopting different legislative and administrative strategies that support the development of FLOSS. Some governments have actually begun to procure FLOSS, whereas others have channeled public funds to large-scale FLOSS projects. This study demonstrates both the benefits and the risks of government policy favoring FLOSS from the perspective of economics, technology, and politics, and to further analyze whether these same policy goals can be achieved through government support of FLOSS. The most fundamental argument of the study is that, in lending its support to FLOSS, the difference between a government user and a business user is that the government should take into account society’s long-term interests, not merely its own interests as a consumer. His research interests include free/open source software, intellectual property, and digital technology policy.     

A hypothetical construct to evaluate intracranial stimulation as a source of motivation

An explanation is offered for the excessive continued responding found when intracranial stimulation is the primary source of motivation for learning. A response pattern which appears cannot be easily broken.     

Attitudes toward the unconscious

As a keynote to a conference bringing together psychoanalysts and analytical psychologists, this paper addresses different mythic attitudes toward the unconscious, Starting with the caricatures of Oedipus and Narcissus that the author feels Jung and Freud originally projected onto each Other in the course of their quarrel. He moves on to the fairytale-like stories of Perseus and Beauty and the Beast to discover mote complex images of the stance taken in relation to the unconscious by present-day analysts: working within both die Jungian and the Freudian traditions.     

Living toward the end

Human beings look to the end as terminus, a passing away when the individual's life story will be complete. Against a cultural tendency to deny death, Christians—claiming a Creator God who does not die—can accept their finitude in principle and aspire to a “high definition” ending. That hope is threatened by the devastating reality of dementia. But Kierkegaard reminds us that the “positive third” of selfhood is not to be identified with mentality and Whitehead stresses that the reception of the inrushing world does not depend on conscious mentality. Against the prevalent culture of individualism, a person of faith can recognize the constitutive role of community past and present. She can find in her terminus a telos, a passing on of life to the others as she steps aside. Is there more? The Newer Testament proclaims a new creation in which life's ending is transformed by the sense of end as beginning, end as advent. This omega as alpha entails both continuity and discontinuity. As to discontinuity, the Christian envisions a life “beyond Eden,” where the perilous gift of freedom is transformed in an integrating knowledge of self, world, and God—fulfilling the calling given to all as created in God's image. This sense of end does not function as an “escape to a transcendent elsewhere,” but motivates and empowers the believer to care for the suffering victims of this volatile and violent age.     

Getting closer: Synchronous interpersonal multisensory stimulation increases closeness and attraction toward an opposite-sex other in female participants

Experiencing tactile facial stimulation while seeing synchronous stimulations delivered to another’s face induces enfacement, i.e. the subjective experience of ownership over the other's face. The synchronous Interpersonal Multisensory Stimulation (IMS) procedure leading to enfacement induces changes beyond the bodily sense of self, such as increased feeling of closeness between self and other. However, evidence for such an influence of IMS on higher-level self-other representations remains limited. Moreover, research has been restricted to settings involving a same-sex other. The current study tested, in female participants, whether IMS could promote social closeness and attraction toward an opposite-sex other. Across two experiments, enfacement with an opposite-sex face was successfully obtained. Synchronous (vs. asynchronous) IMS yielded greater closeness with the other and induced greater Liking and Attraction scores. These novel findings add further evidence to the existence of a link between body representation and social cognition. Implications for interpersonal attraction are discussed.
