The impact of omitting the interaction between crossed factors in cross‐classified random effects modelling

Cross‐classified random effects modelling (CCREM) is a special case of multi‐level modelling where the units of one level are nested within two cross‐classified factors. Typically, CCREM analyses omit the random interaction effect of the cross‐classified factors. We investigate the impact of the omission of the interaction effect on parameter estimates and standard errors. Results from a Monte Carlo simulation study indicate that, for fixed effects, both coefficients estimates and accompanied standard error estimates are not biased. For random effects, results are affected at level 2 but not at level 1 by the presence of an interaction variance and/or a correlation between the residual of level two factors. Results from the analysis of the Early Childhood Longitudinal Study and the National Educational Longitudinal Study agree with those obtained from simulated data. We recommend that researchers attempt to include interaction effects of cross‐classified factors in their models.     

Mands for information generalize across establishing operations

The current study extends the literature on teaching mands for information by assessing whether mands generalize across different establishing operations (EOs). Three children with autism were taught to perform multiple behavior chains, 3 of which included a common response (e.g., “Where is the spoon?”) used for different purposes. An interrupted-behavior-chain procedure was used to contrive the EO for each mand. After teaching a mand for information under 1 EO, the remaining chains were interrupted to determine whether the mand had generalized to different EOs. For all participants, mands for information generalized across EOs. For 2 participants, a new mand-for-information topography emerged after training.     

Teaching effective hand raising to children with autism during group instruction

We taught 3 children with autism to raise a hand or keep both hands down depending on their status (e.g., having heard a target word, possessing a specific item) using modeling, prompting, and reinforcement. All 3 children acquired accurate hand-raising skills in response to progressively more difficult discrimination tasks during group instruction. The implications for preparing children for general education settings are discussed.     

On the use of fluency training in the behavioral treatment of autism: a commentary

The substantial demand for behavior-analytic treatment of early childhood autism has been associated with rapid dissemination of treatment procedures to practitioners and caregivers. This level of demand could plausibly induce premature dissemination of treatments that do not yet have sufficient empirical support. We argue that this might have happened with the use of fluency training for learners with autism and identify four areas of research that are necessary to ensure that dissemination efforts are better matched to the available empirical support for this instructional strategy.     

Content Analysis of the Journal of Counseling & Development: Volumes 74 to 84

A content analysis of the research published in the Journal of Counseling & Development (JCD) was conducted for Volumes 74 (1996) through 84 (2006). Frequency distributions were used to identify the most published authors and their institutional affiliations, as well as some basic characteristics (type of sample, gender, and ethnicity) of the study samples. Results are compared with 2 previous content analyses (D. M. Pelsma & J. P. Cesari, 1989; M. E. Williams & W. C. Buboltz, 1999).     

Work Status Congruence’s Relation to Employee Attitudes and Behaviors: The Moderating Role of Procedural Justice

Purpose  

The purpose of this study is to explore procedural justice as a boundary condition of work status congruence’s (WSC) relationships with organizational commitment and organizational citizenship behavior (OCB). WSC is defined as the degree to which an employee’s schedule, shift, full-time or part-time status, and number of working hours, match his or her preferences (Holtom et al. in J Appl Psychol 86:80–93, 2002). This exploration is grounded in the outcome favorability–procedural justice interaction literature (e.g., Brockner in Acad Manag Rev 27:58–76, 2002).     

The efficacy of couples-based interventions for panic disorder with agoraphobia

From this systematic literature review it was concluded that panic disorder with agoraphobia (PDA) can sometimes occur in conjunction with marital problems. Couples-based treatments for PDA – partner-assisted exposure and marital therapy – can be an effective treatment for the condition. It is as effective as individually based cognitive behaviour therapy. Involving partners of people with PDA in therapy may be appropriate in some cases, particularly those in which there are marital difficulties. Couple-focused interventions may enhance the maintenance of treatment gains by facilitating interactions that positively reinforce and perpetuate attempts by people with PDA to enter feared situations and cope with these effectively. People with PDA who have good marital relationships show a better response to both individual and couples-based treatment programmes. In some instances effective couples-based treatment leads to improvement in marital adjustment as well as in PDA symptomatology.     

The brain is not single-minded about inflectional morphology: A response to the commentaries

Jaeger is supportive of our experiment and the claims we make, arguing that the weight of current evidence shows the brain making a distinction between regular and irregular inflectional morphology. Seidenberg & Arnoldussen are unsupportive, criticizing our work on theoretical and methodological grounds. Seidenberg & Arnoldussen’s major worries—that we have misunderstood connectionist theory’s predictions and have committed a “Difficulty Matching Error” in testing them—are important to consider but turn out to be groundless. At bottom, Seidenberg & Arnoldussen fail to recognize the consequences of our choice of German words, rather than English, as stimuli. Once the concept of “difficulty” is given substance in this context, it appears that in German, the brain activates more extensively when dealing with what in the connectionist universe should be, if anything, the easier stimuli, not the harder ones as suggested by Seidenberg & Arnoldussen. Thus regularity cannot be reduced to difficulty.     

Family–oriented treatment for people with alcohol problems in Ireland: a comparison of the effectiveness of residential and community–based programmes

Using a naturalistic design involving consecutive referrals self–selected for family–oriented treatment, forty–two participants from a residential programme and twenty–five participants from a community–based programme were assessed on a range of alcohol–use and psychosocial measures before treatment. A proportion of these cases were assessed after treatment and at six months'follow–up. At six months' follow–up 79 per cent of both the residential and community groups were either abstinent or drinking moderately. However, more members of the residential group (75 per cent) were abstinent at follow–up compared with the community group (36 per cent). In contrast, more members of the community group were moderate drinkers (43 per cent) at follow–up compared with the residential group (4 per cent). At six months' follow–up, compared with the community group, more members of the residential group showed a clinically significant reduction in recent negative consequences of drinking and psychological adjustment problems. Both groups made significant mean gains on indices of alcohol abuse and psychosocial adjustment but there were important intergroup differences. The residential group showed a greater mean reduction in recent negative consequences from drinking but the community group showed a greater mean reduction in the percentage of days' heavy drinking.
