Effects of minimal social cues on trust in the investment game

In anonymous game tasks, individuals’ prosocial behaviour was shown to increase when those individuals were provided with social cues from a third party or bystander. It has been suggested that those social cues can be presented using a configuration suggestive of a face with ‘watching eyes’. This led us to question whether it was possible to provide the watching‐eyes configuration with even weaker facial information, such as a simple dot pattern. By using a minimal social cue paradigm, such as the one described above, the present research found that individuals’ trust toward the trustee increased when they detected the watching‐eyes dot pattern as a source of social cues in two settings: a hypothetical investment game for both college students (Study 1) and customs officers (Study 2); and an actual investment game for college students (Study 3).     

Acquisition and maintenance of trusting behavior

This study determined whether a two-person exchange situation contained natural contingencies for trusting behavior or whether external contingencies were necessary. Pairs of college students worked matching-to-sample problems for money. On each trial there was one problem and the subjects determined which of them would solve it. Trusting behavior was defined as an increase in the number of consecutive problems each subject allowed his partner to work during sessions that also ended with an equitable distribution. Simply, trust was a temporary deviation from equity. A subject could give the problem to the other person (cooperate), or not respond and let the other person take the problem (share). Other possibilities were for both subjects to try to take the problem (complete), or for neither subject to respond and thereby let the person who worked the last problem also work the next one (passive trust). When only four lever pulls were required to distribute a problem (no external contingencies to reach either equity or trust) subjects reached equity, but only minimal trust (strict alternation of single problems) developed in 18 sessions. When 30 or 60 lever pulls were required to distribute a problem (smaller response requirement for passive trust and therefore a contingency for trust), trusting behavior developed after a few sessions (fixed ratio 30) or after several trials of the first session (fixed ratio 60) and it ordinarily expanded gradually to 10 to 15 consecutive problems through passive trust. The aversiveness of the inequity involved in trusting appears to necessitate a contingency for acquisition. Once trust develops, however, this aversiveness is reduced as subjects learn the inequity is only temporary (e.g., once trust was acquired at fixed ratio 60 it was maintained at fixed ratio 4, which would not initially produce it), and the direction of the inequity appears to become of questionable importance (e.g., being behind was alternated over rather than within sessions and usually not in a systematic manner).

Bridging novelty and familiarity-based recognition memory: A matter of timing

Novelty detection is essential to adapt to changes. However, the relationship between novelty detection and visual recognition memory remains unclear. To characterize the temporal dynamics of novelty and its connection to familiarity, we probed early behavioural performance of novelty and familiarity in 31 participants using a speeded go/no-go recognition task with a 600-ms response deadline. Responses to familiarity and novelty produced symmetrical biases and correlated accuracies and biases, but novelty decisions were less accurate and had slower minimal reaction times (410?ms). These processes thus appear to be independent, as suggested by a more efficient system in the case of familiarity, but with common factors bringing overlapping contributions to both processes. This may possibly be explained by the more fluent processing of repeated stimuli, but with familiarity and novelty potentially relying on one decision criterion, as suggested by the correlated and remarkably symmetrical biases. This study supports models that conceptualize novelty and familiarity decisions as two partly overlapping processes.     

传递性关系推理的简约模型——诠释传递性关系推理的新理论

Wynne的简约模型是基于动物的传递性关系推理研究所提出的理论模型。该模型假设：个体的传递性关系推理是通过运用刺激的强化值来表征顺序信息,并比较所呈现刺激之间强化值的差异来实现的。研究文献证实简约模型能够说明在人类和其它动物的传递性关系推理研究中所发现的大多数标准化效应,因此其被视为迄今解释传递性关系推理问题最经济的模型。但该模型将人类高级认知活动采用动物的机械学习方式来解释的还原论倾向是值得商榷的,它所探讨的传递性行为是否是“真传递性关系推理”也有待进一步验证。     

A Metaphilosophical Analysis of the Core Idea of Deflationism

In this paper, I give a metaphilosophical analysis of the core idea of deflationism by discussing some basic conceptual and methodological issues involved in the debate between deflationism and substantivism. In so doing, I argue for three positive points. First, the crux of the dispute between deflationism and substantivism is whether or not truth is substantive in its metaphysical nature and in its explanatory role in philosophical enterprises, rather than whether or not a minimal approach regarding conceptual resources is taken to explain truth; a minimal approach itself is philosophically innocent. Second, there is no intrinsic connection between the core idea of deflationism and the Tarski-style equivalence thesis, which is often identified as implying or supporting the former. Third, there are some unbridged fundamental gaps between the core idea of deflationism and various redundancy theses; these redundancy theses cannot be identified as the former, nor can they be used to justify the former on their own.

高血压脑出血微创治疗及手术时机的决策探讨

为了比较幕上高血压脑出血传统开颅与微创治疗的效果及其并发症,并对其手术时机进行探讨,对30例传统开颅组和104例微创治疗组进行对比研究。结果显示,术后6个月微创治疗组致残率及肺部感染发生率较传统开颅组明显为低(P0.05);早期(8h～24h)手术死亡率较超早期(8h)明显为低(P0.05)。因此,微创治疗能够有效降低高血压脑出血患者的致残率和术后并发症的发生率,其手术时机适宜选择在早期。

Residues in the analyst of the patient's symbiotic connection at a somatic level: unrepresented states in the patient and analyst

This paper discusses the residues of a somatic countertransference that revealed its meaning several years after apparently successful analytic work had ended. Psychoanalytic and Jungian analytic ideas on primitive communication, dissociation and enactment are explored in the working through of a shared respiratory symptom between patient and analyst. Growth in the analyst was necessary so that the patient's communication at a somatic level could be understood. Bleger's concept that both the patient's and analyst's body are part of the setting was central in the working through.
