Mental multiplication and working memory

This paper is concerned with the role of working memory resources in mental multiplication. In two experiments a dual-task paradigm was used. In the first experiment neutral tapping was contrasted to three modalityspecific secondary tasks: Irrelevant speech and articulatory suppression were used to disrupt the phonological loop and a visuo-spatial tapping was used to disrupt the visuo-spatial sketchpad. Multiplication sums needed to be solved mentally and results needed to be spoken aloud. Sums varied in difficulty (easy, e.g., 3 x 4 =, difficult, e.g., 8 x 17 =). Results from the first experiment revealed declines in performance on difficult sums under articulatory suppression but no interference effect for easy sums. To investigate the role of central executive processes, a second experiment extended the range of interference conditions to a central executive interference task (random letter generation). Now articulatory suppression and random generation caused a decrease of performance on difficult sums. In addition, performance on easy sums was negatively impacted by random letter generation as well. We infer that solving complex multiplication sums demands phonological loop and central executive processes, whereas retrieving numerical facts in solving simple multiplication sums requires only central executive processes. We found no evidence of modality-specific access to numerical facts stored in long-term memory.     

Multiple paths to transfer and constraint relaxation in insight problem solving

In two experiments participants received various training methods designed to relax constraints present in the Four-Tree problem (deBono, 1967 deBono, E. 1967. The use of lateral thinking, London: Jonathan Cape.  [Google Scholar]), a difficult insight problem. Geometry misconceptions were corrected via direct instruction. Participants’ difficulty with developing three-dimensional representations was addressed via spontaneous analogical transfer (Experiment 1) or via cued analogical transfer (Experiment 2). We found that, while both training methods were effective, alleviating multiple constraints was more effective than the alleviation of single constraints via training programmes (c.f.

Committing to your work, spouse, and children: Implications for work-family conflict

When trying to balance work and family responsibilities, many workers experience conflict between these two roles. Although role commitment has been viewed both as contributing to and alleviating conflict, this relationship has not been fully tested. Using a sample of female nurses and police officers, we examined the direct and indirect relationship of role commitment with work-spouse and work-parent conflict. Increased work-spouse conflict was associated with decreased spouse commitment. Increased work-parent conflict was associated with increased parent commitment but with decreased spouse and job commitment. Job commitment moderated the relationships between irregular work schedules and work-spouse conflict and between job control and work-spouse conflict. Parent commitment moderated the relationship between irregular work schedules and work-parent conflict. These results suggest that, depending on the role, commitment may either alleviate or exacerbate conflict.     

The martial arts and mental health: the challenge of managing energy

The effective management of energy is an important dimension in the martial arts as well as the mental health professions. The Oriental concept of Ki is described, noting its Indian, Chinese, and Japanese development. Ki and the transfer of energy is studied through the martial encounter, using concepts borrowed from Japanese swordsmanship. Ki is also discussed from a developmental context as youngsters progress in Tae Kwon Do training. In examining the disciplines of Aikido, Tae Kwon Do, and Karate, it becomes clear that more is involved than kicking, punching, and throwing bodies on the floor. These martial arts have some important statements to make in the area of mental health, particularly in terms of energy--within our bodies, psyches, interpersonal relationships, and the universe.     

Apollo's oracle: Strategizing for peace

This paper examines the role of power structures and strategic decisions in trajectories toward war and peace. Part I introduces a fuzzy inference engine for computationally simulating balance of power. Part II compares simulation results from hegemonic, bi-polar, and multi-polar system structures, each with three actors. Part III explores strategies for maximizing peace under each of these system structures. Part IV applies these lessons to real-world event chronologies.     

Language processing in bilinguals

The present study investigated the language processing strategies of three subgroups of adult bilinguals with different histories of language acquisition: infant bilinguals whose bilinguality dated from infancy; childhood bilinguals who became bilingual around 5 years of age; and adolescent bilinguals who had become bilingual at secondary school age only. All were completely balanced bilinguals in French and English at the time of testing. The experimental procedure, a language recognition task, required the subjects to indicate, by pressing a response button, whether each of a series of words, presented monaurally through earphones, was French or English. Concomitantly, left and right hemisphere EEG activity was monitored, with measures taken of latency to N₁, latency to P₂, and N₁-P₂ peak-to-peak amplitudes. Results indicated shorter latencies to N₁ in the left than in the right hemisphere for the infant and childhood bilinguals but shorter latencies in the right hemisphere for the adolescent bilinguals. Overall, the N₁ latency was shorter for the adolescent subgroup than for the two other subgroups. There were no RT differences. The findings appear to reflect strategy differences: The adolescent group seemed to rely more on a right hemisphere-based, possibly more gestalt-like or melodic strategy, while the early bilinguals relied more on a left hemisphere-based, possibly semantic or analytic type of strategy. The results are discussed in terms of previous research on bilingual subtypes and general forms of language processing among bilinguals.     

Providing Ongoing Skill Development and Support for Educators and Parents of Students with Emotional and Behavioral Disabilities

Target six of the national agenda to improve outcomes for students with or at risk of emotional disturbance is reviewed. Having discussed this target with multiple stakeholders, the authors present four underlying themes that support ongoing skill development of providers and parents alike. These include building capacity of providers, decreasing isolation of school staff, gaining commitment of all school staff to support students with challenging behavior, and including parents and family members in staff development activities. The four underlying themes are discussed and recommendations given for ensuring ongoing skill development and support in education.     

Beyond pleasure: emotion activity affects the relationship between attitudes and behavior

The research examined an additional proposed moderator of the attitude-behavior relationship: the activity level of emotions associated with an attitude object. In Experiment 1, participants who self-generated active rather than passive emotions as being associated with gay men displayed greater attitude-behavior consistency in hiring recommendations for a gay job applicant, as did participants who rated active rather than passive experimenter-provided emotions as being associated with gay men. In Experiment 2, participants who were instructed to associate active rather than passive emotions with gay men subsequently displayed greater attitude-behavior consistency in similar hiring recommendations. It is suggested that future research on the affective component of attitudes might benefit from going beyond consideration of whether the associated emotions entail displeasure or pleasure.
