Exploring the dynamics of design fluency in children with and without ADHD using artificial neural networks

The neuropsychology of attention deficit/hyperactivity disorder (ADHD) has been extensively studied, with a general focus on global performance measures of executive function. In this study, we compared how global (i.e., endpoint) versus process (i.e., dynamic) measures of performance may help characterize children with and without ADHD using a design fluency task as a case study. The secondary goal was to compare the sensitivity of standard versus connectionist statistical models to group differences in cognitive data. Thirty-four children diagnosed with ADHD and 37 children without ADHD aged 8–11 years old were tested on the Five-Point Test. The continuous process measure of performance, indexed as the number of produced designs at each consecutive 1 minute interval during 5 minutes, was analyzed against the discrete process measure, that is, the number of designs between first and last intervals and the standard global performance measure of total number of produced designs. Results show that the continuous process measure distinguished the two groups better than the two other measures. The detailed observation of production patterns revealed a decreasing linear trajectory in children without ADHD that contrasts with the flat, but fluctuating productivity pattern of children with ADHD. With regards to the second goal, results show that the connectionist and standard methods are equally sensitive to group differences for the three types of measures. This illustrates the utility of quantitative process measures together with the connectionist method in neuropsychological research and suggests great potential for a dynamical approach to cognition.     

Life Design Counseling: A study on client's operations for meaning construction

This study evaluated the adequacy of the micro-theory of client operations to explain meaning construction during Life Design Counseling. Four adolescents were interviewed about their second counseling session. Their recollections were stimulated through the replay of counseling videotapes. The resulting transcribed interviews were qualitatively analyzed. Results confirmed a sequence of client operations evolving from the symbolic representation of experience and reflexive self-examination towards making new realizations and revisioning self. Moreover, clients reported negative and positive session moments evidencing that clients' attention and activity during the session was not restricted to meaning construction operations. Practical implications for life design counseling are derived from the results and discussed.     

Failing to commit: Maximizers avoid commitment in a way that contributes to reduced satisfaction

Past research suggests that individuals who approach decisions with the goal of maximizing, or selecting the best possible option, show less satisfaction with their choices than those with the goal of satisficing, or selecting the first “good enough” option. The present investigation examines whether this difference in choice satisfaction stems from a difference in willingness to commit to one’s choices. We argue that maximizers are reticent to commit to their choices and that this reticence robs them of the dissonance reduction processes that leave people satisfied. In Study 1, maximizers reported a stronger preference than satisficers for retaining the possibility to revise choices, both when reporting preferences in their own life and when choosing between options in a hypothetical situation. In Study 2, satisficers showed evidence of classic dissonance reduction after making a choice - they offered higher ratings of a chosen poster and lower ratings of the rejected alternatives, relative to baseline. However, maximizers were less likely to change their impressions of the posters after their choice, leaving them less satisfied with their selected poster. These results provide valuable insight into post-decision processes that decrease maximizers’ satisfaction with their decisions.     

Triggering Individual Emergence: Inspiration of Banathy,the Visionary

This paper examines how metaphors can play a key role in triggering individual emergence. Metaphor is referenced in two main ways: the enthalpy metaphor is used to provide understanding of, and guide, the process of effective conversation. Metaphor is also interpreted very broadly to define those images, analogies, concepts, models, and theories that define our understanding of the world and our perception. It is our perception that must change if we are to improve the future. The paper examines how sharing of appropriate metaphor through conversation can lead to collective emergence; and similarly, how integral conversation-with-self triggered by metaphors in (1) conversation with others, (2) other external stimuli, and (3) internal thought processes, can trigger individual emergence. The paper examines which of the three sources of trigger may be singly/jointly or sequentially the most powerful in their effect of triggering individual emergence, and under what context. The model presented is evaluated for the process of emergence of the paper. The reader is invited to participate in furthering the evaluation process. The author's own individual emergence is recognized as stemming from ongoing association with, and inspiration of, Bela Banathy, to whom the work is dedicated.     

Explaining and Explaining Away in Science and Religion

Abstract

There is no good reason to think that there is a necessary conflict between science and the existence of God, but is there still some way in which science might support atheism? The most plausible strategy for atheism is to argue that scientific explanations can remove the need for God in some cases via “explaining away.” This paper proposes a number of questions to help identify whether explaining away takes place in a given context, and explores several cases where explaining away might be thought to occur, with particular attention given to the most obvious case: the theory of evolution.     

The best of possible worlds: A testable claim of choice

Leibniz said that the universe, if God-created, would exist at a unique, conjoint, physical maximum: Of all possible worlds, it would be richest in phenomena, but its richness would arise from the simplest physical laws and initial conditions. Using concepts of “variety” and algorithmic informational complexity, Leibniz' claim can be reframed as a testable theory. This theory predicts that the laws and conditions of the actual universe should be simpler, and the universe richer in phenomena, than the presence of observers would require. Tegmark has shown that inhabitants of an infinite multiverse would likely observe simple laws and conditions, but also phenomenal richness just great enough to explain their existence. Empirical observations fit the claim of divine choice better than the claim of an infinite multiverse. The future of the universe, including its future information-processing capacity, is predicted to be endless.     

Facilitating Local Implementation of Special Education Program Evaluation

The results of a project assessing the applicability of four program evaluation models is described. Survey data from districts documented an interest in local-level special education evaluation models. A training institute for local staff was therefore established to provide staff with competency in four evaluation models. Subsequently, the models were replicated in eight local sites from which representatives had expressed an interest in using the models. All sites completed evaluation planning and implementation activities. Findings suggest that each of the four models in the project can be used with minimal levels of outside assistance and can be readily adapted to local needs. However, each model places somewhat different demands on local staff; and some models may be more appropriate for particular evaluation purposes.

A Multi‐Family Group Intervention for Adolescent Depression: The BEST MOOD Program

Depression is the most common mental disorder for young people, and it is associated with educational underachievement, self‐harm, and suicidality. Current psychological therapies for adolescent depression are usually focused only on individual‐level change and often neglect family or contextual influences. The efficacy of interventions may be enhanced with a broader therapeutic focus on family factors such as communication, conflict, support, and cohesion. This article describes a structured multi‐family group approach to the treatment of adolescent depression: Behaviour Exchange Systems Therapy for adolescent depression (BEST MOOD). BEST MOOD is a manualized intervention that is designed to address both individual and family factors in the treatment of adolescent depression. BEST MOOD adopts a family systems approach that also incorporates psychoeducation and elements of attachment theories. The program consists of eight multifamily group therapy sessions delivered over 2 hours per week, where parents attend the first four sessions and young people and siblings join from week 5. The program design is specifically aimed to engage youth who are initially resistant to treatment and to optimize youth and family mental health outcomes. This article presents an overview of the theoretical model, session content, and evaluations to date, and provides a case study to illustrate the approach.     

Choice among two and three alternatives

Although choice between two alternatives has been widely researched, fewer studies have examined choice across multiple (more than two) alternatives. Past models of choice behavior predict that the number of alternatives should not affect relative response allocation, but more recent research has found violations of this principle. Five pigeons were presented with three concurrently scheduled alternatives. Relative reinforcement rates across these alternatives were assigned 9:3:1. In some conditions three keys were available; in others, only two keys were available. The number of available alternatives did not affect relative response rates for pairs of alternatives; there were no significant differences in behavior between the two and three key conditions. For two birds in the three‐alternative conditions and three birds in the two‐alternative conditions, preference was more extreme for the pair of alternatives with the lower overall pairwise reinforcer rate (3:1) than the pair with higher overall reinforcer rate (9:3). However, when responding during the changeover was removed three birds showed the opposite pattern in the three‐alternative conditions; preference was more extreme for the pair of alternatives with the higher overall reinforcer rate. These findings differ from past research and do not support established theories of choice behavior.
