Functionplane—A new approach to simple structure rotation

A new criterion for rotation to an oblique simple structure is proposed. The results obtained are similar to that obtained by Cattell and Muerle's maxplane criterion. Since the proposed criterion is smooth it is possible to locate the local maxima using simple gradient techniques. The results of the application of the Functionplane criterion to three sets of data are given. In each case a better fit to the subjective solution was obtained using the functionplane criterion than was reported for by Hakstian for the oblimax, promax, maxplane, or the Harris-Kaiser methods.This paper is contribution No. 66 from the Program in Ecology and Evolution at the State University of New York, Stony Brook, New York.

Form recognition: Individual strategies in multivariate cue utilization

Twenty-five Ss were each presented 1,250 trials in a form-recognition task requiring S to find a form among 25 other forms on each trial. Fifty different eight-sided randomly derived polygons were used as stimuli, each presented in 25 different problems. Factors based on physical measures of the stimuli were correlated with observed latencies using multiple regression to assess cue-utilization strategies, while beta-weight profiles and intercorrelations of the Ss’ predicted latencies were used as indices of individual differences. Multiple correlations of physical-factor scores with observed latencies accounted for a significant proportion of the variance for all Ss, while between-S correlations of predicted latencies were never below .90. By all criteria employed, use of stimulus information was highly consistent among Ss. Replication of the experiment for one S revealed good reliability and nearly identical strategies.     

DNA markers associated with general and specific cognitive abilities

Multivariate quantitative genetic research suggests a hierarchical model of cognitive abilities where genetic effects are largely general, cutting across most cognitive abilities. Some genetic effects, however, are specific to certain cognitive abilities. These results lead to a hypothesis for molecular genetic research: Although most genes associated with one cognitive ability will be related to other cognitive abilities, some genes will be specific to a particular cognitive ability. The current research explored this hypothesis in an analysis of data in specific cognitive abilities from 86 children from 6 to 12 years of age from a larger allelic association study of general cognitive ability. Eight DNA markers were entered simultaneously in separate multiple regression analyses predicting each of four specific cognitive ability factors (Verbal, Spatial, Perceptual Speed, Memory), as well as WISC-R subtest scores. Four marjers (CTGB33, EST00083, HLA, and SOD2) showed similar effects across the cognitive ability scales, suggesting that they are related to general cognitive ability (g). These associations became negligible when the effects of ‘g’ (WISC-R IQ) were removed. Three markers (ADH5, DM, and NGFB) continued to be significantly associated with specific cognitive ability scales after the effects of ‘g’ were removed. Although preliminary, these molecular genetic results support the hierarchical model predicted by quantitative genetic research.     

Elements of a counter‐exhibition: Excavating and countering a Canadian history and legacy of eugenics

Into the Light, a recently mounted collectively curated museum exhibition, exposed and countered histories and legacies of 20th‐century “race betterment” pedagogies taught in Ontario's postsecondary institutions that targeted some groups of people, including Anishinaabe, Black, and other racialized populations, and disabled and poor people, with dehumanizing ideas and practices. This article advances understandings of the transformative potential of centralizing marginalized stories in accessible and creative ways to disrupt, counter, and draw critical attention to the brutal impacts of oppressive knowledge. The “counter‐exhibition” prioritized stories of groups unevenly targeted by such oppression to contest and defy singular narratives circulating in institutional knowledge systems of what it means to be human. The authors draw on feminist, decolonial and disability scholarship to analyze the exhibition's curation for the ways it collectively and creatively: (1) brought the past to the present through materializing history and memory in ways that challenged archival silences; and (2) engaged community collaboration using accessible, multisensory, multimedia storytelling to “speak the hard truths of colonialism” (Lonetree) while constructing a new methodology for curating disability and access (Cachia). The authors show how the exhibition used several elements, including counter‐stories, to end legacies of colonial eugenic violence and to proliferate accounts that build solidarity across differences implicated in and impacted by uneven power (Gaztambide‐Fernández).     

How Does the Life Satisfaction of the Poor,Least Educated,and Least Satisfied Change as Average Life Satisfaction Increases?

We study subjective life satisfaction inequality in the United States using panel data from the 2005 to 2010 Behavioral Risk Factor Surveillance System. We aggregate individual level data to the state level and study how the average self-reported life satisfaction of various income, education, and life satisfaction groups changes with the average self-reported life satisfaction of the state. We find that the subjective life satisfaction of the least satisfied does not increase in equal proportion with the average life satisfaction of society, suggesting that increasing satisfaction levels are likely to lead to greater life satisfaction inequality. However, the life satisfaction of the poorest and least educated does increase in equal proportions with average life satisfaction.     

Treating destructive behavior reinforced by increased caregiver compliance with the participant's mands

Functional analyses sometimes do not identify momentary fluctuations in the function of destructive behavior (Bowman, Fisher, Thompson, & Piazza, 1997). In such cases, individuals may mand for the reinforcer that is currently most preferred and display destructive behavior if that mand goes unreinforced. In this study, we conducted a mand analysis to test whether destructive behavior functioned as a precurrent response that increased reinforcement for the participant's mands. We then evaluated a treatment that matched this function of destructive behavior by providing differential or time-based reinforcement of participant mands in accordance with multiple or chained schedules with reinforcement-schedule thinning. Decreases in destructive behavior averaged 97.4% across cases. We discuss these results relative to the importance of matching treatments for destructive behavior to operant functions for both traditional and idiosyncratic functions of destructive behavior.     

The effects of a motivational general-arousal imagery intervention upon preperformance symptoms in male rugby union players

ObjectivesTo investigate the efficacy of a motivational general-arousal based imagery strategy in modifying precompetitive symptom interpretations.MethodA staggered multiple baseline single-subject design was employed with five male collegiate rugby union players (M = 24.5; SD = 3.05). The dependent variable was monitored over a full competitive season via measures of precompetitive anxiety and affect together with follow-up social validation procedures.ResultsMore facilitative interpretations of symptoms associated with competitive anxiety, and greater self-confidence levels were reported postintervention, together with changes in positive and negative affect.ConclusionsThe findings highlight the importance of employing individualized imagery with motivational general-arousal content to modify performers' perceptions of their precompetitive experiences. This effect is proposed to occur directly through adaptive changes in individuals' psychological response systems and indirectly via the protection mechanisms associated with enhanced efficacy expectations.
