A conjunctive feature similarity effect for visual search

Traditional models of visual search assume interitem similarity effects arise from within each feature dimension independently of other dimensions. In the present study, we examine whether distractor-distractor effects also depend on feature conjunctions (i.e., whether feature conjunctions form a separate “feature” dimension that influences interitem similarity). Spatial frequency and orientation feature dimensions were used to generate distractors. In the bound condition, the number of distractors sharing the same conjunction of features was higher than that in the unbound condition, but the sharing of features within frequency and orientation dimensions was the same across conditions. The results showed that the target was found more efficiently in the bound than in the unbound condition, indicating that distractor-distractor similarity is also influenced by conjunctive representations.     

Beyond change management: a multilevel investigation of contextual and personal influences on employees' commitment to change

The extent to which attitudes toward organizational changes may be affected by contextual (other changes going on) and personal (self-efficacy) factors was investigated with a multilevel design involving 25 different changes. Even after aspects of the change itself were controlled, the interaction between the context and the individual difference explained significant variance in attitudes toward those specific changes. The positive relationship between self-efficacy and commitment to the change was stronger as the amount of simultaneous and overlapping change in the surroundings increased. The implications for research and practice are discussed.     

Empowerment or disempowerment? A review of youth training schemes for non-engaged young people in Hong Kong

This paper investigates the school-to-work experiences of non-engaged youth aged 15-24 who do not participate in education, training, and employment. Based on data from focus groups involving 50 non-engaged young people in Hong Kong, it examines how they are being systematically propelled to the edges of conventional pathways to adulthood, and assesses the efficacy of governmental training schemes that aim to develop employability as a strategy for engaging this population. The paper concludes by outlining prospects for future policy development, focusing on gaps and weaknesses in current provision and practice. It is suggested that effective guidance for non-engaged young people must pay attention to the social context of the individual. Assumptions behind the government's individualistic lifelong learning policy are called into question.     

Setting goals, solving problems, and seeking social support: developing adolescents' abilities through a life skills program

The Going for the Goal (GOAL) program is designed to teach adolescents life skills. There have been few efforts to assess whether the skills that GOAL is designed to teach are being learned by adolescents involved in the program. The purpose of this study was to examine the impact of GOAL on the acquisition of skills in the areas of setting goals, solving problems, and seeking social support. Interviews were conducted with twenty adolescents. Those who participated in GOAL reported that they had learned how to set goals, to solve problems effectively, and to seek the appropriate type of social support.     

Jung and Kabbalah: imaginal and noetic aspects

Jung made use of kabbalistic images and motifs in various parts of his opus, including in his alchemical studies, in Aion, and extensively in Mysterium Coniunctionis. He also recorded an important dream after his heart attack which made use of kabbalistic symbolism in Memories, Dreams, Reflections. In this paper I explore Jung's ideas in relation to Kabbalah, first, by differentiating between Jung's imaginal approach to kabbalistic symbolism and the noetic intention of the Kabbalah itself in its use of imaginal material. Second, I present a number of typical examples of how Jung understands (and sometimes misunderstands) kabbalistic material that he cites. Third, I briefly survey the development of the Kabbalah as an imaginal noetic system, and present a core self-understanding of kabbalists--as engaged in inner 'self-work' which intends to 'sweeten the harsh judgments of existence in their very roots'. Finally, I differentiate Jung's understanding of the psychical living symbol from the kabbalistic understanding of the mystical symbol. In this fourth section of the paper, I conclude by presenting a basic Hasidic/kabbalistic teaching on the nature and function of verbal contemplative prayer--as an illustration of the difference between the two understandings of symbolism. The four sections of the paper are framed by a 'Prelude' and a 'Coda'.     

What do people desire in others? A sociofunctional perspective on the importance of different valued characteristics

Humans, as discriminately social creatures, make frequent judgments about others' suitability for interdependent social relations. Which characteristics of others guide these judgments and, thus, shape patterns of human affiliation? Extant research is only minimally useful for answering this question. On the basis of a sociofunctional analysis of human sociality, the authors hypothesized that people highly value trustworthiness and (to a lesser extent) cooperativeness in others with whom they may be interdependent, regardless of the specific tasks, goals, or functions of the group or relationship, but value other favorable characteristics (e.g., intelligence) differentially across such tasks, goals, or functions. Participants in 3 studies considered various characteristics for ideal members of interdependent groups (e.g., work teams, athletic teams) and relationships (e.g., family members, employees). Across different measures of trait importance and different groups and relationships, trustworthiness was considered extremely important for all interdependent others; the evidence for the enhanced importance of cooperativeness across different interdependence contexts was more equivocal. In contrast, people valued other characteristics primarily as they were relevant to the specific nature of the interdependent group or relationship. These empirical investigations illuminate the essence of human sociality with its foundation of trust and highlight the usefulness of a theoretically derived framework of valued characteristics.     

Activation of premotor vocal areas during musical discrimination

Two same/different discrimination tasks were performed by amateur-musician subjects in this functional magnetic resonance imaging study: Melody Discrimination and Harmony Discrimination. Both tasks led to activations not only in classic working memory areas--such as the cingulate gyrus and dorsolateral prefrontal cortex--but in a series of premotor areas involved in vocal-motor planning and production, namely the somatotopic mouth region of the primary and lateral premotor cortices, Broca's area, the supplementary motor area, and the anterior insula. A perceptual control task involving passive listening alone to monophonic melodies led to activations exclusively in temporal-lobe auditory areas. These results show that, compared to passive listening tasks, discrimination tasks elicit activation in vocal-motor planning areas.     

Using vision and dynamic touch to perceive the affordances of tools

The information that people use to perceive whether a tool is suitable for a certain task depends on what is available at a given time. Visually scanning a tool and wielding it each provide information about the functional attributes of the tool. In experiment 1, we investigated the relative contributions of vision and dynamic touch to perceiving the suitability of various tools for various tasks. The results show that, when both vision and dynamic touch are available, the visual information dominates. When limited to dynamic touch, ratings of suitability are constrained by the inertial properties of the tool, and the inertial properties that are exploited depend on the task. In experiment 2, we asked whether the manner in which a tool is manipulated in exploration depends on the task for which it is being evaluated. The results suggest that tools are manipulated in ways that reflect intentions to perceive particular affordances. Exploratory movements sometimes mimic performatory movements.     

月经周期对女性知觉性侵犯遭遇的影响

女性在排卵期遭遇强奸或其它形式的性侵犯可能会受到较大伤害。进化历史中女性遭遇性侵犯的危险不断重现使现代社会女性在排卵期对男性性侵犯的线索较为敏感。本研究旨在探讨女性被试观看男性试图吸引其它女性的录像后如何评价每位男性性侵犯的可能性。研究发现接近排卵期的女性比不处于排卵期的女性更可能认为男性会进行性侵犯。这些发现显示,女性具有特定的知觉进化机制来警惕性侵犯,这种特定的进化机制可能受到月经变化的调节
