Notes on a Journey From Symbols to Multifractals: A Tribute to Guy Van Orden

Rejecting traditional cognitive science put us in a bind. On the one hand, traditional cognitive science is our heritage; our curiosity about the big questions of cognition led us initially to invest in the conventional approaches. On the other hand, we eventually became dissatisfied with the fundamentals of traditional cognitive science. Rather than criticize from the sidelines, we struggled for a new way to address the same problems with a new explanatory framework. Guy Van Orden spurred us forward on 2 counts. First, his work inspired us to consider fractal scaling as a new framework for exploring change in cognitive structure. Second, his provocative contrast between pink and white noises as diagnostic of interactions and components, respectively, intrigued us. Our struggle for a new direction became a struggle to understand what Guy meant and how his ideas might translate within our research domains. Guy helped us to forge a perspective that would have surprised us before, namely, the perspective that cognitive and, more generally, biological structure reflects turbulent flows structured over many different scales with multifractal fluctuations.     

Rich contexts do not always enrich the accuracy of personality judgments

We test the common assumption that information ‘rich’ contexts lead to more accurate personality judgments than information ‘lean’ contexts. Pairs of unacquainted students rendered judgments of one another's personalities after interacting in one of three, increasingly rich, contexts: Internet ‘chat’, telephone, or face-to-face. Accuracy was assessed by correlating participants' judgments with a measure of targets' personalities that averaged self and informant ratings. As predicted, the visible traits of extraversion and conscientiousness were judged more accurately than the less visible traits of neuroticism and openness. However, judgment accuracy also depended on context. Judgments of extraversion and neuroticism improved as context richness increased (i.e., from Internet ‘chat’ to face-to-face), whereas judgments of conscientiousness and openness improved as context richness decreased (i.e., from face-to-face to Internet ‘chat’). Our findings suggest that context richness shapes not only the availability of personality cues but also the relevance of cues in any given context.     

Deductive temporal reasoning with constraints

When modelling realistic systems, physical constraints on the resources available are often required. For example, we might say that at most N processes can access a particular resource at any moment, exactly M participants are needed for an agreement, or an agent can be in exactly one mode at any moment. Such situations are concisely modelled where literals are constrained such that at most N, or exactly M, can hold at any moment in time. In this paper we consider a logic which is a combination of standard propositional linear time temporal logic with cardinality constraints restricting the numbers of literals that can be satisfied at any moment in time. We present the logic and show how to represent a number of case studies using this logic. We propose a tableau-like algorithm for checking the satisfiability of formulae in this logic, provide details of a prototype implementation and present experimental results using the prover.     

The Use of a Child-Based Acceptance and Commitment Therapy Curriculum to Increase Attention

Acceptance and Commitment Therapy (ACT) is a treatment that integrates mindfulness and acceptance training with behavior change processes. One of the core processes in ACT is contact with the present moment which involves shifting attention to what is happening here and now, contacting both internal and external stimuli. An experimental and control group were used to determine the impact ACT had on attention. ACT participants (M?=?5.4, SD?=?9.8) showed fewer inaccuracies on the CPT-X task compared to the control group (M?=?19.75, SD?=?16.1) at posttest F(1, 38)?=?11.49, p?=?.02, ηp²?=?.232. Results of the current study demonstrate participation in the use of an ACT curriculum for children to help increase attention outcomes.     

Singaporean kindergartners' phonological awareness and English writing skills

This article describes the phonological awareness and English writing skills among a sample of 297 Singaporean kindergarten children, stratified by ethnicity (Chinese, Malay, and Indian), and examines the relationship between oral language and writing skills in this multilingual population. Overall, Singaporean kindergartners, nearly all of whom were bilingual, scored higher on English writing but lower on English oral language skills than U.S. norms. Despite literacy instruction that emphasized whole-word memorization, phonological awareness statistically significantly predicted English writing scores, controlling for English vocabulary, ethnicity, sex, and an interaction between English vocabulary and sex. The current study's findings highlight the possibility of developing high literacy skills among bilingual learners with low oral language skills. In addition, the study demonstrates children's development of phonological awareness in the absence of phonological awareness or phonics instruction and supports the theory that both alphabetic (phonological) processes and logographic (whole-word) processes contribute to successful English literacy achievement.     

Derived transformation of children's pregambling game playing

Contemporary behavior-analytic perspectives on gambling emphasize the impact of verbal relations, or derived relational responding and the transformation of stimulus functions, on the initiation and maintenance of gambling. Approached in this way, it is possible to undertake experimental analysis of the role of verbal/mediational variables in gambling behavior. The present study therefore sought to demonstrate the ways new stimuli could come to have functions relevant to gambling without those functions being trained directly. Following a successful derived-equivalence-relations test, a simulated board game established high- and low-roll functions for two concurrently presented dice labelled with members of the derived relations. During the test for derived transformation, children were reexposed to the board game with dice labelled with indirectly related stimuli. All participants except 1 who passed the equivalence relations test selected the die that was indirectly related to the trained high-roll die more often than the die that was indirectly related to low-roll die, despite the absence of differential outcomes. All participants except 3 also gave the derived high-roll die higher liking ratings than the derived low-roll die. The implications of the findings for behavior-analytic research on gambling and the development of verbally-based interventions for disordered gambling are discussed.     

Effect of Representational Distance Between Meanings on Recognition of Ambiguous Spoken Words

Previous research indicates that mental representations of word meanings are distributed along both semantic and syntactic dimensions such that nouns and verbs are relatively distinct from one another. Two experiments examined the effect of representational distance between meanings on recognition of ambiguous spoken words by comparing recognition of unambiguous words, noun–verb homonyms, and noun–noun homonyms. In Experiment 1, auditory lexical decision was fastest for unambiguous words, slower for noun–verb homonyms, and slowest for noun–noun homonyms. In Experiment 2, response times for matching spoken words to pictures followed the same pattern and eye fixation time courses revealed converging, gradual time course differences between conditions. These results indicate greater competition between meanings of ambiguous words when the meanings are from the same grammatical class (noun–noun homonyms) than when they are from different grammatical classes (noun–verb homonyms).

In this article, the authors offer a comprehensive overview of the counseling profession in Denmark. The history and development of counseling is considered, followed by a review of the current state of Danish professional counseling. Finally, impressions of the future of professional counseling in Denmark are presented based on the past and current trends.     

Hospital Privileges for Psychologists in the Era of Competencies and Increased Accountability

After campaigning to be granted hospital privileges decades ago, new issues are emerging that are affecting psychologists’ hospital privileges. Some of the forces shaping hospital privileges emanate from within the field of psychology, where there has been a movement to more closely examine psychologists’ competences. Other forces impinging on hospital privileges are external to psychology, most notably the Joint Commission, which has promulgated new standards for hospital-based practitioners across disciplines. This article discusses the effects of these new standards on the practice of psychology and describes the findings of a survey examining how privileges are currently obtained and maintained within hospitals.
