颜色词的语用关系影响颜色认知

在汉语中, 红、紫、蓝、绿都有各自的语言标签。但在日常语用中, “红”与“紫”比“蓝”与“绿”的语用关系更加密切。“红”与“紫”具有更多的联合表达, 具有更为类似的颜色感应。采用颜色相似性判断、颜色分类和颜色再认任务, 考察汉语母语者对“红–紫”色块和“蓝–绿”色块的认知, 探讨语用关系对颜色认知的影响。结果表明, 语用关系不影响汉语母语者的颜色相似性判断, 却影响颜色分类和颜色再认。与“蓝–绿”色块比, 汉语母语者在包含记忆成分任务中对“红–紫”色块具有认知劣势。整个研究表明, 由语用关系引起的颜色感应在颜色认知中起着重要调节作用, 记忆编码在此过程中起着直接作用。     

Conspiracies of immanence: Paul Tillich,Pierre Teilhard de Chardin and C.G. Jung

Jung's psychology proffers a sustained reflection on the traditional religious question of the relation of divine transcendence to immanence. On this issue his psychology affirms a position of radical immanence in its contention that the experience of divinity is initially wholly from within. Though this position remains on the periphery of religious and theological orthodoxy Jung is not alone in holding it among moderns. Paul Tillich adopts a similar stance with his controlling symbols of the divine as ‘Ground of Being’ and ‘Depth of Reason’. Pierre Teilhard de Chardin understands divinity as the experiential energy of evolution itself working within nature and humanity toward greater configurations of universal communion as the basis of community. All of Jung's master symbols of individuation assume such an understanding of immanence uniting individual and totality. His psychology strongly suggests and contributes to the current emergence of a new religious sensitivity based on the awareness of the intra‐psychic origin of all religions. In his later writings he held out such a position as a significant alternative to genocide.     

Clinical applications of Matte Blanco's thinking

Ignacio Matte Blanco (1908–1995) left very few specific indications about the applications of his theoretical notions to his interpretative style. The author shows how he uses Matte Blanco to formulate some of his own interpretations. The first part of the paper uses clinical vignettes to illustrate some of Matte‐Blanco's concepts. Their theoretical vocabulary is thus made explicit. Then two psychoanalytic sessions are discussed at greater length, together with one from a therapy, so that the use of Matte‐Blanco's notions can be seen clearly, allowing for a fresh perspective on areas of psychoanalytic theory, particularly dreams, psychopathology viewed according to the proportions of asymmetrical and symmetrical functioning in the patient's bi‐logical mental system, the multidimensionality of the unconscious, the structural unconscious, the emotion‐thought relationship, projective identification, resistance, and negative therapeutic reaction. The practical consequences of all this are elaborated, particularly the ensuing possibility of ‘thinking with the patient' in the session. This enables the patient to introject a form of mental functioning in which the asymmetrical mode is not invaded by the symmetric mode (a parallel can be seen here with the Bionian concept of dialogue between the psychotic and non‐psychotic parts of the mind).     

Optimal kicking of a trampolinist

This work aims to create a mathematical model by using kinematical equations that can describe the landing-jump of a trampoline performance. In this model, the trampolinist was assumed to be a combination of two parts of masses. The landing process (from the time trampolinist touches the net to the deepest location) was discretized into two stages. During these two stages, the trampolinist exerts different internal forces. Analyzing the kinematics of the abovementioned two stages, we obtained the numerical solutions for the optimum loading time and loading force of the trampolinist to get the deepest landing location. This work has potential for guiding a trampolinist in developing his/her personalized optimal strategy for exerting force during landing on the trampoline.     

A job demands-resources perspective on salespersons’ market intelligence activities in new product development

Research shows that R&D's use of sales’ market intelligence positively influences innovation performance. However, little is known about whether this effect hinges on salespersons’ engagement towards and perceptions of market intelligence activities (MIA). Moreover, research remains incomplete regarding the drivers of salespersons’ MIA engagement. Using dyadic data from 359 salespersons and 239 R&D managers in a multi-level model based on the job demands-resources theory, we demonstrate that the positive effect of R&D's use of sales’ market intelligence on innovation performance is especially pronounced when salespersons’ market intelligence generation is high and role ambiguity is low. We also show that although salespersons’ self-set MIA goals are a strong driver of their MIA engagement, not assigning salespersons MIA goals may be a double-edged sword: in the short run, salespersons might engage in MIA voluntarily. However, in the long run, they could incur psychological costs in terms of role ambiguity and conflict, preventing them from engaging in MIA.     

Measurement and comparative analysis of driver’s perception–reaction time to green phase at the intersections with and without a countdown timer

This paper proposes a method based on digital image processing for measuring drivers’ perception–reaction time (PRT) to the green phase. The detection of the onset of a green signal was based on the RGB color model. The detection of the start of the vehicle was based on the frame difference. The driver’s perception–reaction time was equal to the difference between the frame of the onset of the green signal and the frame of the start of the vehicle divided by the video frame rate. Drivers’ PRT with and without a countdown timer were comparatively analyzed. First, the means and variances of drivers’ PRT with a timer and without a timer were compared. Second, Normal, Lognormal, Gamma and Weibull distributions were used to fit the PRT data. Third, the fuzzy c-means clustering was utilized for PRT classification and comparison. The results show that the method for measuring drivers’ PRT based on digital image processing was effective. The drivers’ PRT was decreased from 2.12 s to 1.48 s with countdown signals. Weibull distribution appeared to best fit the PRT with No-Timer and Lognormal distribution appeared to best fit the PRT with Timer. The PRT data were classified into three groups: “Fast”, “Moderate” and “Slow”. Clustering centers without Timer were 1.16 s, 2.47 s and 3.98 s respectively. Clustering centers with Timer were 0.95 s, 1.64 s and 2.70 s respectively. The clustering centers can be regarded as reference values of drivers’ starting response for microscopic traffic simulation software.     

Similar changes in muscle fiber phenotype with differentiated consequences for rate of force development: Endurance versus resistance training

Resistance training has been shown to positively affect the rate of force development (RFD) whereas there is currently no data on the effect of endurance training on RFD. Subjects completed ten weeks of either resistance training (RT, n = 7) or endurance cycling (END, n = 7). Pre and post measurements included biopsies obtained from m. vastus lateralis to quantify fiber phenotype and fiber area and isokinetic dynamometer tests to quantify maximal torque (Nm) and RFD (Nm/s) at 0–30, 0–50, 0–100 and 0–200 ms during maximal isometric contraction for both knee extensors and flexors. Both groups increased the area percentage of type IIa fibers (p < .01) and decreased the area percentage of type IIx fibers (p = .05), whereas only RT increased fiber size (p < .05). RT significantly increased eccentric, concentric and isometric strength for both knee extensors and flexors, whereas END did not. RT increased 200 ms RFD (p < .01) in knee flexor RFD and a tendency towards an increase at 100 ms (p < .1), whereas tendencies towards decreases were observed for the END group at 30, 50 and 100 ms (p < .1), resulting in RT having a higher RFD than END at post (p < .01). In conclusion, resistance training may be very important for maintaining RFD, whereas endurance training may negatively impact RFD.

Distorted estimates of implicit and explicit learning in applications of the process-dissociation procedure to the SRT task

We investigated potential biases affecting the validity of the process-dissociation (PD) procedure when applied to sequence learning. Participants were or were not exposed to a serial reaction time task (SRTT) with two types of pseudo-random materials. Afterwards, participants worked on a free or cued generation task under inclusion and exclusion instructions. Results showed that pre-experimental response tendencies, non-associative learning of location frequencies, and the usage of cue locations introduced bias to PD estimates. These biases may lead to erroneous conclusions regarding the presence of implicit and explicit knowledge. Potential remedies for these problems are discussed.     

Reinforcement sensitivity theory at work: punishment sensitivity as a dispositional source of job-related stress

Gray's reinforcement sensitivity theory (RST) describes two important personality constructs; sensitivity to reward and sensitivity to punishment. In two studies, we examine whether these constructs can be considered dispositions to work stress. Results of Study 1 (N = 105 employees in different occupations) indicated that employees with strong punishment sensitivity reacted more strongly to work stressors than others. This idea was confirmed in a longitudinal design in Study 2. Reward sensitivity was unrelated to stress in both studies. Overall, results strongly support the idea that punishment sensitivity is a dispositional source of work stress. Results further confirm that RST and its derived personality measures can contribute to theorizing about personality–environment interactions in a highly relevant daily setting, namely the working environment.
