Chisholm on Perceptual Knowledge: Foundationalism versus Coherentism

Abstract: Chisholm refuted phenomenalism as a theory of the justification of perceptual beliefs. He argued, following Thomas Reid, that some perceptual beliefs were justified in themselves, which provided a foundation for empirical knowledge. The question that remains is whether the foundational justification provided offers an adequate explanation of how justification is connected with truth. The search for a truth connection led me from foundationalism to a coherence theory of justification that, contrary to my intentions, was inspired by an observation of Chisholm himself.     

Complete Axiomatizations for Reasoning about Knowledge and Branching Time

Sound and complete axiomatizations are provided for a number of different logics involving modalities for the knowledge of multiple agents and operators for branching time, extending previous work of Halpern, van der Meyden and Vardi [to appear, SIAM Journal on Computing] for logics of knowledge and linear time. The paper considers the system constraints of synchrony, perfect recall and unique initial states, which give rise to interaction axioms. The language is based on the temporal logic CTL*, interpreted with respect to a version of the bundle semantics.     

Psychoeducational Interventions with Pediatric Cancer Patients: Part I. Patient Information and Knowledge

We present a systematic review of published research on psychoeducational interventions for children with cancer. The current lack of an organizational model for this literature makes it difficult to form a coherent picture of the scattered literature and draw nomothetic conclusions. A model is described that is based on functional concepts from the literature on learning and instructional design. It is argued that it makes sense conceptually to analyze psychoeducational interventions in terms of psychoeducational principles, especially if the purpose is to illuminate the learning processes involved. Three categories of intervention are distinguished and the first of these, informational interventions to influence patient knowledge, is considered in this paper, and the other two categories will be reviewed in a subsequent paper. This review is organized by categories of information needs, intervention modes, and major types of independent variables. We concluded that the research supports few generalizable conclusions at this time, except that development of health-related knowledge in children is best accomplished by information transfer methods that are highly interactive and individualized. Interactive multimedia formats such as video games are seen as having the best potential, but further research is required.     

知识点认知规律的实验研究

知识点是人的认知单位,人学习知识,必须以知识点为单位、逐个知识点地学习。本实验以概念学习为例,研究了人一次学习一个知识点与同时学习两个知识点时的成绩差异。研究结果表明,1. 在概念中的信息组块数不超过短时记忆容量的前提下,一次学习一个概念,构成概念的信息组块数对概念掌握影响不显著。2.在同样条件下,一次学习一个知识点的成绩好于同时学习两个知识点的成绩,从而验证了知识点认知规律。     

Two modes of confidence rating: An effect of episodic information of participant's own past responses in a repeated-question paradigm

Abstract: General knowledge questions with two answer alternatives were employed in experimental session 1; in session 2, the same questions were presented together with participants' own session-1 responses. In order to examine whether or not the episodic information of participant's own responses would suppress standard confidence-rating mode in session 2, rates of answer- and confidence-changes between sessions were analyzed. In session 2, participants were able to change the confidence value to another, if they thought the initial value inadequate. They then had a chance to change the answer to the other and rated their confidence in the new answer. The major results were as follows: (a) Between-session answer change rate was very low; (b) Between-session answer change rate was not a monotonic decreasing function of confidence; (c) However, the rate depended on confidence change from session 1 to before-answer-change rating. These results clearly contrasted with a previous study ( Saito, 1998 ) in which episodic information of participant's own session 1 answers and confidence values was not presented. It was argued that the episodic information triggered another mode of confidence rating or a decision inertia effect.     

Women are not less field independent than men—the role of stereotype threat

Prior research has shown that females are less field independent (FI) than males. However, when gender identity is salient, performance on tests assessing constructs similar to FI may be hindered, because of stereotype threat. This study examined the impact of stereotype threat on gender differences in FI. We expected that (a) reporting one's own gender prior to FI testing and (b) having an opposite‐gender experimenter would activate stereotype threat, and in turn result in lower performance on a test of FI among females. Overall, 170 participants were randomly assigned to one of eight conditions in a between‐participants design varying the participant's gender, experimenter's gender and timing of the gender question (before vs. after test). Results showed that reporting one's gender before the FI test led to lower FI performance among females. Furthermore, females achieved higher FI when experimenters were females and gender questions were administered after the FI test.     

Creative Thinking Processes: The Past and the Future

For more than one hundred years, students of creativity, including seminal efforts published in the Journal of Creative Behavior , have sought to identify the key processes people must execute to produce creative problem solutions. In recent years, we have seen a consensual model of key creative thinking processes being accepted by the field. In the present effort, we review the evidence bearing on the eight core processes proposed in this consensual model. Subsequently, directions for future research on creative thinking processes are discussed.     

Visual orienting and attention deficits in 5- and 10-month-old preterm infants

Cognitive outcomes for children born prematurely are well characterized, including increased risk for deficits in memory, attention, processing speed, and executive function. However, little is known about deficits that appear within the first 12 months, and how these early deficits contribute to later outcomes. To probe for functional deficits in visual attention, preterm and full-term infants were tested at 5 and 10 months with the Infant Orienting With Attention task (IOWA; Ross-Sheehy, Schneegans and Spencer, 2015). 5-month-old preterm infants showed significant deficits in orienting speed and task related error. However, 10-month-old preterm infants showed only selective deficits in spatial attention, particularly reflexive orienting responses, and responses that required some inhibition. These emergent deficits in spatial attention suggest preterm differences may be related to altered postnatal developmental trajectories. Moreover, we found no evidence of a dose-response relation between increased gestational risk and spatial attention. These results highlight the critical role of postnatal visual experience, and suggest that visual orienting may be a sensitive measure of attentional delay. Results reported here both inform current theoretical models of early perceptual/cognitive development, and future intervention efforts.     

The relationship between executive function and fine motor control in young and older adults

The present study examined the relationship between executive function (EF) and fine motor control in young and older healthy adults. Participants completed 3 measures of executive function; a spatial working memory (SWM) task, the Stockings of Cambridge task (planning), and the Intra-Dimensional Extra-Dimensional Set-Shift task (set-shifting). Fine motor control was assessed using 3 subtests of the Purdue Pegboard (unimanual, bimanual, sequencing). For the younger adults, there were no significant correlations between measures of EF and fine motor control. For the older adults, all EFs significantly correlated with all measures of fine motor control. Three separate regressions examined whether planning, SWM and set-shifting independently predicted unimanual, bimanual, and sequencing scores for the older adults. Planning was the primary predictor of performance on all three Purdue subtests. A multiple-groups mediation model examined whether planning predicted fine motor control scores independent of participants’ age, suggesting that preservation of planning ability may support fine motor control in older adults. Planning remained a significant predictor of unimanual performance in the older age group, but not bimanual or sequencing performance. The findings are discussed in terms of compensation theory, whereby planning is a key compensatory resource for fine motor control in older adults.     

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.
