The role of prior exposure in the capture of attention by items in working memory

The Biased Competition Model (BCM) suggests both top-down and bottom-up biases operate on selective attention (e.g., Desimone & Duncan, 1995). It has been suggested that top-down control signals may arise from working memory. In support, Downing (2000) found faster responses to probes presented in the location of stimuli held vs. not held in working memory. Soto, Heinke, Humphreys, and Blanco (2005) showed the involuntary nature of this effect and that shared features between stimuli were sufficient to attract attention. Here we show that stimuli held in working memory had an influence on the deployment of attentional resources even when: (1) It was detrimental to the task, (2) there was equal prior exposure, and (3) there was no bottom-up priming. These results provide further support for involuntary top-down guidance of attention from working memory and the basic tenets of the BCM, but further discredit the notion that bottom-up priming is necessary for the effect to occur.     

The basic components of adult playfulness and their relation with personality: The hierarchical factor structure of seventeen instruments

The primary aim of this study was testing the structure of adult playfulness in a joint analysis of seventeen questionnaires and testing the relation of the factors with the big five personality traits. A sample of 244 adults completed the questionnaires and a five factor-solution fit the data best; i.e., (a) Humorousness; (b) Cheerfulness–Uninhibitedness; (c) Expressiveness; (d) Other-directedness; and (e) Intellectuality–Creativity. Correlation analyses (bivariate, canonical) and regression analyses indicated strong overlap of the broader personality factors and the Cheerfulness–Uninhibitedness-factor (extraversion and emotional stability) as well as the Expressiveness-factor (extraversion). The study contributes towards a better understanding of the structure of playfulness in questionnaires developed for adults. Implications for future research are discussed.     

Abducted by Bayesians?

This paper discusses the role of theoretical notions in making predictions and evaluating statistical models. The core idea of the paper is that such theoretical notions can be spelt out in terms of priors over statistical models, and that such priors can themselves be assigned probabilities. The discussion substantiates the claim that the use of theoretical notions may offer specific empirical advantages. Moreover, I argue that this use of theoretical notions explicates a particular kind of abductive inference. The paper thus contributes to the discussion over Bayesian models of abductive inference.     

Does the form of employment make a difference?—Commitment of traditional, temporary, and self-employed workers

Increasing change in the labor market has produced new forms of employment. A growing number of people have temporary jobs or are self-employed freelancers. The aim of our study is to address these changes by introducing commitment to the form of employment as a new focus in commitment. In addition, we compare organizational commitment under conditions of these forms of employment to traditional form of employment. The study is based on several samples representing conventional and new forms of employment (overall N = 494). The results indicate that commitment to the form of employment explains variance of organizational outcomes over and above organizational commitment. Generally, commitment to the form of employment reflects an important attitude to the work situation besides commitment to the organization or occupation. The results are discussed in the light of labor market trends.     

NONEMPIRICAL REALITY: TRANSCENDING THE PHYSICAL AND SPIRITUAL IN THE ORDER OF THE ONE

I describe characteristic phenomena of quantum physics that suggest that reality appears to us in two domains: the open and well‐known domain of empirical, material things—the realm of actuality—and a hidden and invisible domain of nonempirical, non‐material forms—the realm of potentiality. The nonempirical forms are part of physical reality because they contain the empirical possibilities of the universe and can manifest themselves in the empirical world. Two classes of nonempirical states are discussed: the superposition states of microphysical entities, which are nonempirical because observation destroys them, and the virtual states of material systems, which are nonempirical because they are empty. The non‐empirical part to physical reality represents a predetermined and hidden order that exists before it is empirical, and the visible world is an emanation out of it. I discuss consequences for our understanding of human nature, the origin of life, and human values. Reality is an indivisible wholeness that is aware of its processes, like a Cosmic Spirit, and it reveals its awareness in the mindlike properties of elementary processes as well as in the human consciousness. Thus, one is led to G. W. F. Hegel's thesis that the Cosmic Spirit is thinking in us.     

Social Scientists in Times of Crisis: The Structural Transformations Within the Disciplinary Organization and Thematic Repertoire of the Social Sciences

This is a contribution to thesociology and social epistemology of knowledgeproduction in Russian social sciences today. Inthe initial section, the epistemic status andsocial function of Soviet social scientificdiscourse are characterized in terms of textualforms and their modes of (re-)production. Theremaining sections detail the course of therestructuration of social scientific discoursesince the fall of the Soviet Union and draw onextant empirical sources, in particular studiesof bibliographical rubrics, thematicrepertoires, and current textual formsthroughout the public sphere and the academicestablishment in Russia. An underlying concernis the shifting status of the intellectual inthe wider socio-cultural context as reflectedin language usage and its textualembodiments.     

Counselling and well-being: on the road to realities

This article aims to discuss the rationale and some guiding principles for the realm of counselling in the fostering of well-being. After some brief observations of a theoretical nature, the principles analysed are: the revitalisation of counselling; the reflection on the concept of dialogue, including the notion of context; the perspective of counselling as social activity; understanding counselling and how it adjusts on the road to realities. From this perspective, practitioners view counselling as a social activity aimed at self-construction and life designing. In following that view, the idea of counselling as being socially produced is also examined. At the end, some considerations on the future of counselling are discussed.     

Plato on the role of contradiction in education

In this paper, I will look at two passages from the discussion of education in Book VII of Plato’s Republic: 523b-524d and 537e-539d. These passages, when taken together, present a puzzle for the coherency of the educational programme Socrates describes. Both discuss contradiction. One says that contradiction is educationally edifying, the other, that it is corrupting. This sounds like a contradiction about contradiction. As far as I know, no one has noticed this puzzle before. By the end of this paper, I hope to have not only provided a solution to the apparent contradiction about contradiction that is compelling, but also one that shows that this puzzle, which might at first have seemed restricted to a textual issue about the educational programme in the Republic, is in fact one that has far reaching implications for a range of Plato’s theories across several dialogues. Along with education, corruption, and contradiction, I will discuss Plato’s theory of psychology, and his theory of forms.     

ERP signatures of conscious and unconscious word and letter perception in an inattentional blindness paradigm

A three-phase inattentional blindness paradigm was combined with ERPs. While participants performed a distracter task, line segments in the background formed words or consonant-strings. Nearly half of the participants failed to notice these word-forms and were deemed inattentionally blind. All participants noticed the word-forms in phase 2 of the experiment while they performed the same distracter task. In the final phase, participants performed a task on the word-forms. In all phases, including during inattentional blindness, word-forms elicited distinct ERPs during early latencies (∼200–280 ms) suggesting unconscious orthographic processing. A subsequent ERP (∼320–380 ms) similar to the visual awareness negativity appeared only when subjects were aware of the word-forms, regardless of the task. Finally, word-forms elicited a P3b (∼400–550 ms) only when these stimuli were task-relevant. These results are consistent with previous inattentional blindness studies and help distinguish brain activity associated with pre- and post-perceptual processing from correlates of conscious perception.     

Effects of variation in teacher organization on classroom functioning

This study examined effects of variation in teacher organization on how time is spent in classrooms, focusing on time spent in transitions and instruction, including child skill by teacher organization interactions. Forty-four first-grade classrooms were observed three times over the school year. Timed narratives of each activity were recorded. “Orient-organize” referred to time teachers spent orienting students to classroom procedures or organizing the class for specific assignments, and included instructional clarity, where teachers described objectives of activities to students. Using hierarchical linear modeling, substantial variation across teachers in orient-organize was observed. Overall, classrooms spent less time in organization as the school year progressed. In addition, spending more time in organization was related to less time spent in transition. Students in classrooms that spent more time in organization in the fall also experienced greater amounts of time in child-managed activities in the spring. There was also an interaction between child vocabulary and amount of orient-organize in the winter. Students with lower vocabulary scores were more likely to be in classrooms that spent more time in spring child-managed activities if they continued to receive substantial amounts of orient-organize in the winter. The opposite was the case for students with high vocabulary skills.
