Influence of distal and proximal cues in encoding geometric information

Vertebrates use geometric and featural information for spatial navigation. When both geometric and featural cues are available, animals can use a variety of spatial strategies based on this information. To examine the nature of these strategies, we manipulated the spatial relationship between a conspicuous cue and the position of the goal when goldfish (Carassius auratus) were searching for the exit of a rectangular environment with one distinctive wall. Two groups of fish were used, one with the distinctive wall close to the goal and the other with the distinctive wall on the other end of the enclosure. Results showed that fish encoded featural and geometric information in both conditions but the spatial relationship between the goal and the distinctive wall influences the characteristics of the encoding of the spatial cues and the strategy used to locate the goal. These results suggest that fish in both procedures use the local featural cues associated with the goal instead of the whole set of spatial cues as previous studies propose.     

自我调节学习量表的修订:发展性研究

现有的自我调节学习研究的工具适用范围受到一定限制。依据心理测量学原理随机抽取了1115名青少年进行自我调节学习量表的施测和修订。结果表明:(1)修订后的量表由三个维度构成:动机,策略,意志;(2)各量表的信度和效度均达心理测量学标准,有较好的适用性;(3)修订后的自我调节学习量表适用的年龄范围较以往研究工具更为广泛。     

Illusory conjunctions reflect the time course of the attentional blink

Illusory conjunctions in the time domain are binding errors for features from stimuli presented sequentially but in the same spatial position. A similar experimental paradigm is employed for the attentional blink (AB), an impairment of performance for the second of two targets when it is presented 200–500 msec after the first target. The analysis of errors along the time course of the AB allows the testing of models of illusory conjunctions. In an experiment, observers identified one (control condition) or two (experimental condition) letters in a specified color, so that illusory conjunctions in each response could be linked to specific positions in the series. Two items in the target colors (red and white, embedded in distractors of different colors) were employed in four conditions defined according to whether both targets were in the same or different colors. Besides the U-shaped function for hits, the errors were analyzed by calculating several response parameters reflecting characteristics such as the average position of the responses or the attentional suppression during the blink. The several error parameters cluster in two time courses, as would be expected from prevailing models of the AB. Furthermore, the results match the predictions from Botella, Barriopedro, and Suero’s (Journal of Experimental Psychology: Human Perception and Performance, 27, 1452–1467, 2001) model for illusory conjunctions.     

汉学视野中卫氏父子的《周易》译介与研究

本文试图通过回顾德国汉学家卫礼贤和卫德明父子在德语和英语世界对《周易》的翻译、介绍和研究,呈现他们独特的研究视角和鲜明的问题意识。他们把人生乃至人类的基本问题纳入《周易》文本的解读之中,同时试图在《周易》中寻找对中国心灵、智慧和文化思维的理解,在西方之外寻找更具普遍性的宇宙智慧。他们以自身独特的方式在西方文化世界中＂翻开＂了《周易》,其要旨不在于传播有关《周易》的确切知识,而是启发人们思考和探讨《周易》所蕴藏的文化与思想/思维可能性,从而对自身在当下的生存境遇进行精神的内省。     

Gender-role's attitude, perceived similarity, and sexual prejudice against gay men

Two hundred and twenty-six heterosexual participants (115 women and 111 men) were asked to indicate their attitude toward gender-roles, their perceived similarities with gay men, and their attitude toward gay men (i.e., sexual prejudice). As expected, male participants showed more sexual prejudice than female participants, and perceived dissimilarities were related to a greater sexual prejudice. Support for gender-roles was related to sexual prejudice for male participants, but not for female participants. More interestingly, the three-way interaction suggested that perceived similarities moderated the link between gender-roles and sexual prejudice among heterosexual men, but not among heterosexual women. Attitude in favor of traditional gender-roles was related to sexual prejudice for male participants who perceived gay men as different, but not for those who perceived gay men as similar. These findings are discussed in terms of the defensive function of men's attitude toward homosexuality as a result of threat to masculinity.     

Efficacy and feeling of a vibrotactile Frontal Collision Warning implemented in a haptic pedal

A haptic pedal has been designed to emulate the behaviour of a common vehicle pedal and render superimposed vibrations with different characteristics. It was installed in a driving simulator, as an accelerator pedal with the secondary function of a vibrotactile Frontal Collision Warning (FCW). The efficacy and feeling of this solution was tested with 30 subjects using vibrotactile signals with 0.50, 1.05, and 1.60 Nm, at 2.5, 5, and 10 Hz, against a baseline visual FCW. Participants had to match the speed of a leading vehicle when the FCW was triggered. Their braking response was evaluated in terms of brake reaction time, matching speed time, control of velocity and headway reduction. Driver’s feelings were assessed with Kansei methodologies. Haptic stimuli were found to be more effective than visual signals, and the characteristics of the vibration also influenced the results. The best performance was achieved at the maximum amplitude, and in the range between 5 and 10 Hz. The perceived functionality and discomfort followed a trend coherent with the objective measurements. The conclusions of this study may be applied to develop effective and safe warning systems in vehicles, limiting the annoyance that they might cause to drivers.     

What matters in the associative learning of visual cues in foraging parasitoid wasps: colour or brightness?

Visual cues are known to be used by numerous animal taxa to gather information on quality and localisation of resources. Because environmental lighting can interfere with the spectral features of visual cues, the specific characteristics of the colour signals that promote forager decision and learning are still not known in the majority of insects (excepted in bees). We analysed the effect of previous experience on the use of visual information by the wasp Venturia canescens, a parasitoid of pyralidae, in the context of host searching. These parasitoids search for hosts concealed in several fruit species, so visual cues from the host microhabitat could play a key role in host finding. We also investigated the type of visual cues on which wasps based their decision. We tested whether wasps are able to associate an achromatic cue (brightness) or a chromatic one (hue, i.e. dominant wavelength and/or chroma) with the presence of hosts. Our results show that in the context of host foraging, chromatic cues are more reliable than brightness in achieving the associative learning process. Therefore, understanding the behavioural ecology of foraging should make use of the knowledge about the visual information used.     

“授人以筌”——评析卡尔·罗杰斯的学习理论

在教学上人们一直围绕着教育是"授人以鱼"还是"授人以渔"展开激烈的讨论,"鱼"和"渔"何者为重,似乎毋庸置疑。人本主义心理学的创始人之一罗杰斯把从事数十年的心理治疗方法"来访者中心疗法"应用到教育领域,在"鱼"和"渔"的选择上二者皆抛,提出的以学生为中心的学习理论体现了一种"授人以筌"的教育理念。本文从其学习理论的提出、教育理念等方面予以说明。
