Toward accurate inferences of response class membership

In their review of synthesis within the functional analysis (FA) literature, Slaton and Hanley (2018) reported that most synthesized contingency analyses have included multiple topographies of problem behavior in the reinforcement contingency class. This leaves the question of whether one, some, or all forms of problem behavior are sensitive to the synthesized reinforcement contingencies in published analyses. To address this ambiguity, all topographies of problem behavior that were reported by caregivers to co-occur with the most concerning problem behavior were analyzed for 10 participants. We implemented extinction across one or more forms of problem behavior to determine whether all forms reported to co-occur were sensitive to the same synthesized reinforcement contingency. For nine of 10 participants, the most concerning topographies were sensitive to the same synthesized reinforcement contingencies as the less concerning topographies (results were inconclusive for one). Implications for inferring response class membership from single analyses are discussed.     

Place of Birth, Place of Residence, and Concentration in Social Occupations

To explore the hypothesis that people who migrate across international, provincial, and state borders tend to veer away from occupations that require intense social interaction, demographic data were obtained on 2,638 North Americans who have attained eminence within their chosen fields. Occupations were blind-coded either as "social" or "nonsocial." While there were similar concentrations in social occupations among Native Americans (75.00%) and Native Canadians (73.02%), there were successively fewer social occupations among Canadian emigres (59.53%), world (predominantly European) emigres (51.46%), and Asian emigres (40.99%) to the U.S. Findings suggest that Asian Americans' well-documented tendencies to veer away from lines of work that involve forceful self-expression reflects a continuous variable rather than a dichotomous variable that sharply separates Asian and North American cultures.     

Infant visual fixation: The effect of concentricity,curvilinearity, and number of directions

The goal of the study was to define certain of the effective dimensions of visual stimulation in the infant's visual environment by analyzing the well-documented preference for the bullseye over a pattern of horizontal stripes. The stimuli were ten black and white patterns, including the bullseye and the stripes, designed to vary along three dimensions: concentricity, curvilinearity and number of directions within the stimulus. The dependent measure was total fixation time corrected for position bias. The subects, 18 three-month-old infants, were tested three times each in order to present them with the ten stimuli in all possible combinations with positions reversed.All three dimensions were found to be effective in varying degrees. The results were discussed in terms of underlying mechanisms and the infant's ability to process information from a multidimensional stimulus.     

Software review

Summary Word Works certainly provides a technological approach to creating educational worksheets. These programs ar designed to enhance instructional management and increase student vocabulary efficiently. Educators with at least word processing capability are able to operate this menudriven program.Given that the appropriateness of instructional worksheets is often bantered about the educational community, the contributions of these programs are somewhat limited. Although it is assumed by the software manufacturers that programs as such are motivating for students, the extended use of such activities are often criticized by educational experts. Further, the on-going use of worksheets is tempered by such student variables as student reading ability, students' age-grade level, and other variables.     

Value Perceptions of Integrative Health Care: A Study of Primary Care Physicians and Professional Clinical Counselors

A study was conducted to identify value perceptions of primary care physicians and Professional Clinical Counselors on integrative health care. Surveys were collected from 54 primary care physicians and 33 Professional Clinical Counselors in Central Ohio. Quantitative and qualitative results indicate favorable perceptions and opportunities for professional collaboration.     

Families and Schools Together: an experimental analysis of a parent-mediated multi-family group program for American Indian children

The goals of this randomized intervention study were to: (a) increase academic performance among American Indian children ages 4-9 years and (b) reduce classroom problem behaviors. To achieve these goals, the multi-family group program called Families and Schools Together (FAST) was adapted with three American Indian Nations in Wisconsin. Over 3 years, seven multi-family group cycles of FAST were implemented, each lasting 8 weeks. In collaboration with the College of Menominee Nation, this parent intervention approach was adapted to express tribal values while maintaining its core components. Fifty pairs of universally recruited American Indian students at three schools who were assessed, matched on five variables, and then randomly assigned to either the FAST or non-FAST control condition. Pretest, posttest, and 9- to 12-month follow-up data were collected by American Indian staff and university students on multiple indicators of academic and behavioral performance. Of the 50 families that attended FAST meetings at least once, 40 graduated (80%) from the 7 FAST cycles. On the immediate posttest, statistically significant differences in improvement, favoring FAST participants were found on the Aggressive Behavior scale of the teacher-rated Child Behavior Checklist (CBCL) and on the parent-rated Withdrawn scale of the same instrument. On the 1-year follow-up assessment, parent CBCL ratings indicated that FAST students had maintained their less withdrawn status and teacher ratings on the Social Skills Rating Scale (SSRS) revealed that FAST participants had exhibited relatively greater improvement in their academic competence. Parent surveys of the graduated students generally showed satisfaction with the program. Implications of the present results and future research directions are discussed.     

Varying Problem Effort and Choice: Using the Interspersal Technique to Influence Choice Towards More Effortful Assignments

College students were exposed to two pairs of mathematics assignments. Assignment Pair A included a high-effort assignment containing 18 long three-digit × two-digit (3×2) multiplication problems with all numerals in each problem being equal to or greater than four and a moderate-effort assignment that contained nine long problems and nine interspersed moderate 3×2 problems with numerals less than four. Assignment Pair B contained similar assignment sheets, the exception being that the high-effort assignment contained six additional one-digit × one-digit (1×1) problems interspersed following every third 3×2 problem. After working on each assignment pair, students ranked assignments and chose a new assignment for homework. Analysis of Assignment Pair A revealed that students overwhelmingly preferred the moderate-effort assignment. Analysis of interaction effects showed that when additional brief problems were added to the high-effort assignments, the proportion of students who chose the high-effort assignment for homework and ranked it as being less difficult, time consuming, and effortful increased significantly. Results support previous research on effort and choice and the hypothesis that a completed discrete problem may serve a reinforcing stimulus.     

Framing the figure: Mental rotation revisited in light of cognitive strategies

The mental rotation literature commonly reports a sex difference, almost always favoring men. Two strategies have been proposed in the literature to account for this difference: holistic and piecemeal. However, there is great variability in rotation performance suggesting other possible contributing factors. This study investigated the effects of stimuli characteristics and habitual spatial thinking on mental rotation performance. In three experiments, participants completed a mental rotation task with two modifications: (1) 3-D figures were presented with their cut versions to promote piecemeal strategy, and (2) block figures were either presented within a frame or none, in light of reference framework model or perceptual grouping model. Overall, whole figures generated faster responses than cut figures and this was more pronounced with greater angular disparity. Shape or the presence of a frame affected rotation performance. Having a frame seemed to impede overall rotation, especially for cut figures, supporting an object-based reference frame. However, a 3-D frame did not have the same effect, possibly suggesting the unitary configuration idea. Men rotated more accurately than women, but still sex was not as robust as it was suggested in the literature. Interestingly, there were similarities between possible strategy use and habitual spatial thinking. People who were categorized as having landmark-centered representations and who preferred verbal directions showed a pattern suggesting the use of a piecemeal strategy, and survey-centered representations and map preference seemed to reflect a holistic strategy.
