Digital LED Pixels: Instructions for use and a characterization of their properties

This article details how to control light emitting diodes (LEDs) using an ordinary desktop computer. By combining digitally addressable LEDs with an off-the-shelf microcontroller (Arduino), multiple LEDs can be controlled independently and with a high degree of temporal, chromatic, and luminance precision. The proposed solution is safe (can be powered by a 5-V battery), tested (has been used in published research), inexpensive (～ $60 + $2 per LED), highly interoperable (can be controlled by any type of computer/operating system via a USB or Bluetooth connection), requires no prior knowledge of electrical engineering (components simply require plugging together), and uses widely available components for which established help forums already exist. Matlab code is provided, including a ‘minimal working example’ of use suitable for use by beginners. Properties of the recommended LEDs are also characterized, including their response time, luminance profile, and color gamut. Based on these, it is shown that the LEDs are highly stable in terms of both luminance and chromaticity, and do not suffer from issues of warm-up, chromatic shift, and slow response times associated with traditional CRT and LCD monitor technology.     

Beliefs in Equality for Women and Men as Related to Economic Factors in Central and Eastern Europe and the United States

Do economic indicators predict the general level of support for gender equality? This question was investigated in a sample of countries in Central and Eastern Europe, a region that has been undergoing rapid economic changes since the early 1990s. In this overall sample of male and female college students from ten countries, including the United States as a comparison, the predicted association between stronger beliefs in gender role egalitarianism and positive economic factors was generally supported. Also, consistent with other research, women were more in support of gender equality than men were. There was no support for a predicted trend in less support for gender equality over the time period of the present study.     

心理治疗效果评定量表(简式)在中、德应用的心理测量学研究(英文)

419名中国和德国被试参加了本研究,并回答了若干简式心理健康量表。所选的这套量表能对心理治疗不同阶段的效果(Howard’s阶段模型:重新认识期-转变期-康复期)进行测查。本研究目的在于考察这些简式量表能否用于认知-行为治疗跨文化培训项目中的质量管理。结果显示,这些量表在中德两种文化背景下都有很高的信度和效度(聚合效度和敏感性)。尽管项目间的高相关似乎提示心理健康模型只有一个维度,但探索性因素和理论分析则更支持心理健康是一个分为8个亚维度的模型,其中每个亚维度或者与基础情绪、或者与社会性情感相连关联。本文最后就研究结果及其对心理治疗质量控制的意义进行了详细讨论。     

Selective networking as identity project: the social integration of first generation immigrants in Norway

Many immigrants try to gain positive recognition in their everyday lives through the active and selective rearrangement of social relations with members of the host community and their own ethnic groups. Amongst other things, their selectivity with respect to who they want to be associated with are expressed through their ethno-social preferences, as well as through the kinds of ties and the sociable intensity they have with their Norwegian and compatriot friends and acquaintances. In this article, I argue that there are tensions and dilemmas connected to these friendships. These tensions can be partly illuminated if we distinguish between the interactional aspects of the ties and the symbolic values that immigrants attach to these ties. The main argument is that for many immigrants, the weak tie attachment to Norwegians seems to be the preferable path of social integration into the mainstream society. Given the focus on immigrants’ voices, the data was gathered through qualitative interviews. Other methods of gathering empirical data, such as from observations, are also used.     

Extraversion is accurately perceived after a 50-ms exposure to a face

Twenty-four perceivers saw portraits of unacquainted persons for either 150 ms, 100 ms, or 50 ms, and rated their personality on adjective scales. Moreover, stimulus persons described themselves on these scales and the NEO Five-Factor Inventory. Consensus among perceivers and self-other agreement were not systematically related to exposure time, but self-other agreement differed strongly between traits, being highest for extraversion. Even ratings of extraversion by single perceivers were related to the stimulus persons’ self-reports. Particularly strong were correlations between perceived extraversion and self-reports on items measuring the extraversion facets excitement seeking and positive emotions. Self-other agreement for extraversion was mostly mediated by cheerfulness of facial expressions that was related to self-reports of extraversion but not of the other personality traits.     

A viewpoint-independent process for spatial reorientation

Reorientation tasks, in which disoriented participants attempt to relocate objects using different visual cues, have previously been understood to depend on representing aspects of the global organisation of the space, for example its major axis for judgements based on geometry. Careful analysis of the visual information available for these tasks shows that successful performance could be based on the much simpler process of storing a visual ‘snapshot’ at the target location, and subsequently moving in order to match it. We tested 4-8-year olds on a new spatial reorientation task that could not be solved based on information directly contained in any retinal projection that they had been exposed to, but required participants to infer how the space is structured. Only 6-8-year olds showed flexible recall from novel viewpoints. Five-year olds were able to recall locations given movement information or a unique proximal landmark, but without these they could not do so, even when they were not disoriented or when the landmark was a familiar object. These results indicate that early developing spatial abilities based on view matching and self motion are supplemented by a later-developing process that takes into account the structure of spatial layouts and so enables flexible recall from arbitrary viewpoints.     

Balance Performance During Perturbed Standing Is Not Associated With Muscle Strength and Power in Young Adults

The authors investigate the ways in which varied postural responses to translating platform perturbations are associated with the variables of strength and power. Twenty-four physically active and 27 sedentary young adults were exposed to a set of postural perturbations at varied velocities (10 and 20 cm/s) and the respective accelerations (6.4 and 6.9 m/s²), constant distance (6 cm), and 4 directions of platform motion (forward, backward, left-lateral, and right-lateral). They also performed maximum voluntary isometric contraction (MVC) and chair rising/chair jumping tests. The analysis of variance revealed significant interaction effect for peak center of pressure displacement, direction by velocity: F_3,129 = 24.43, p = .002; and direction by acceleration: F_3,129 = 34.18, p = .001. There were no significant correlations between peak center of pressure displacements and peak force and peak rate of force development measured during MVC in either standing (r = .27–57) or sitting positions (r = .12–51) and peak power during chair jumping (r = .47–.59) in all participants. As such, only a small proportion of variance was explained (9–39%, 3–23%, and 23–41%, respectively). In conclusion, interaction effects indicate that the composition of stimuli strongly influences compensatory responses and this effect is more pronounced in sedentary than in physically active young adults. Nevertheless, the dynamic balance is not associated with muscle strength and power in either group.     

The Higher Your Implicit Affiliation‐Intimacy Motive,the More Loneliness Can Turn You Into a Social Cynic: A Cross‐Cultural Study

Research has shown that the strength of the implicit affiliation‐intimacy motive moderates the effects of satisfaction and frustration of the need for affiliation‐intimacy: Low relatedness was more closely related to envy for people high in the implicit affiliation‐intimacy motive. The present study tests a moderating effect of the strength of the implicit affiliation‐intimacy motive on the association between low relatedness and social cynicism in samples of elderly people from Germany, the Czech Republic, and Cameroon. A total of 616 participants provided information on their implicit affiliation‐intimacy motive, relatedness, and social cynicism. As hypothesized, a moderation effect of the strength of the implicit affiliation‐intimacy motive was found that held true regardless of participants’ culture of origin: For people high in the implicit affiliation‐intimacy motive, a lack of relatedness was associated with higher levels of social cynicism. Our findings complement other theories stating that positive relationships with others are a significant part of successful aging.

The Interaction of Contextual and Syntactic Information in the Processing of Turkish Anaphors

In contrast with languages where anaphors can be classified into pronouns and reflexives, Turkish has a tripartite system that consists of the anaphors o, kendi, and kendisi. The syntactic literature on these anaphors has proposed that whereas o behaves like a pronoun and kendi behaves like a reflexive, kendisi has a more flexible behavior and it can function as both a pronoun and a reflexive. Using acceptability judgments and a self-paced reading task, we examined how Turkish anaphors are processed in isolated sentences and within larger discourse contexts. We manipulated contextual information by creating passages where the context favored a local, long-distance or extra-sentential referent prior to the appearance of the anaphor. We measured the effect of the context on participants’ reading times and their end-of-trial coreference assignments. Our results suggest that contextual information affects the interpretive possibilities associated with an anaphor, but that the influence of context depends on the degree to which the anaphor is syntactically constrained.
