Concurrent reinforcement schedules: behavior change and maintenance without extinction

We evaluated the effects of concurrent schedules of reinforcement on negatively reinforced problem behavior and task completion with 3 children with autism. Results indicated that problem behavior occurred at high levels and relatively few tasks were completed when problem behavior produced a break (from tasks) and task completion produced either no consequence or a break. By contrast, problem behavior was eliminated and tasks were completed when problem behavior produced a break and task completion produced a break with access to preferred activities. Treatment gains were maintained without the use of extinction when the response requirement was increased and the schedule of reinforcement was thinned.     

Modality Effects and the Development of the Word Length Effect in Children

Two experiments investigated the development of the word length effect in children aged 4 to 10 years, comparing auditory and visual stimuli. The question addressed was whether word length effects emerged earlier with auditory presentation or visual presentation, or whether they emerged at the same age regardless of presentation modality. Results provided evidence that word length effects emerge earlier with visual than auditory presentation. The implication of our results is that with visual presentation, 4-year-olds engage in some form of verbalisation strategy that involves obtaining phonological representations of picture names and mapping them on to articulatory output plans. This strategy is clearly verbal in nature, but is not necessarily characterised as cumulative verbal rehearsal.     

Initiation of evidence-based psychotherapies in Veterans with posttraumatic stress disorder

The Department of Veterans Affairs (VA) requires that all VA hospitals and clinics provide access to evidence-based psychotherapies (EBPs). Despite these widespread dissemination efforts, only a minority of Veterans receive EBP services. Reasons for these low rates of EBP utilization are largely unknown. This study examined the characteristics of Veterans with posttraumatic stress disorder (PTSD) who did (Initiation group) and did not (No-Initiation group) initiate a VA-approved EBP after participating in an information session. Veterans chose their preferred treatment from a menu of EBPs. Results demonstrated that Veterans in the No-Initiation group had longer periods of time between their referral and first EBP visit. Among Veterans in the Initiation group, the majority (68%) initiated a trauma-focused EBP as their first or second treatment, suggesting that providing a range of treatment options did not negatively impact their willingness to engage in PTSD treatment. Results are discussed in terms of VA initiatives to improve access to and initiation of mental health care for Veterans.

The Paradox Between Integration and Perceived Discrimination Among American Muslims

Muslim Americans are increasingly integrated into American life, displaying high socioeconomic status, political participation, and adherence to American values. However, they are evaluated more negatively than many other racial, ethnic, and religious minorities and are frequent targets of discrimination. This article examines the mismatch between the integration of Muslims and their poor reception. Drawing on theories of cultural fluency and cognitive dissonance, we argue that cultural integration can exacerbate, rather than mitigate, perceived discrimination because integrated individuals are socialized to expect fair treatment and can recognize and decode even subtle forms of discrimination due to high levels of cultural and language fluency. Using three nationally representative surveys and an opt-in, online study of American Muslims between 2007 and 2017, we find that integrated Muslims are consistently more likely than their counterparts to report individual- and group-level societal and political discrimination. The paradox between adopting the host culture and feeling marginalized poses a challenge to the assumption that integration naturally leads to a sense of belonging among minorities, with important implications for liberal democracies.     

On a Promise or on the Game: What's Wrong with Selling Consent?

Is selling sex a service like any other? Philosophers have given a range of answers to this question: (a) sex has a specific value that is debased by commercial markets in sex; (b) sex work is a service like any other; (c) markets in sex perpetuate structural systems of inequality. This article takes seriously the suggestion that there is something special about sex itself which raises a specific set of concerns when traded for money. The challenge is to explain this without drawing on contentious essentialist claims about the value of sex. It proceeds by analysing a parallel between sexual promises and selling sexual consent. On an expectational theory of promising, commercial agreements to sex generate obligations in a way that is normatively analogous to sexual promises. Understanding the normative release conditions for such assurance-providing agreements provides a way of analysing the justifiability of various ways of enforcing such agreements. I argue that the release conditions for agreements involving sex are not conducive to being codified under typical forms of service contract. As such, regulation aimed at legitimising sex work must provide adequate protections to workers without codifying it under typical forms of service contract.     

Memory for thematically arousing events

Many studies have indicated that emotional arousal improves memory for the center, or gist, of an event but undermines memory for the event's periphery. However, all of these studies have elicited emotion by showing participants some salient visual stimulus intended to arouse them (e.g., the sight of a wound). This stimulus may have served as an attention magnet, and this, not the arousal, may have been the cause of the observed narrowing of memory. In this article, we examine how participants remember events that involve thematically induced arousal, arousal produced by empathy, rather than by a visual emotional stimulus. The data show that emotionality improves memory for all aspects of these events, with no memory narrowing.     

What's in a name for memory errors? Implications and ethical issues arising from the use of the term "false memory" for errors in memory for details

The term "false memories" has been used to refer to suggestibility experiments in which whole events are apparently confabulated and in media accounts of contested memories of childhood abuse. Since 1992 psychologists have increasingly used the term "false memory" when discussing memory errors for details, such as specific words within lists. Use of the term to refer to errors in details is a shift in language away from other terms used historically (e.g., "memory intrusions"). We empirically examine this shift in language and discuss implications of the new use of the term "false memories." Use of the term presents serious ethical challenges to the data-interpretation process by encouraging over-generalization and misapplication of research findings on word memory to social issues.     

Social effectiveness therapy for children: five years later

Social Effectiveness Therapy for Children (SET-C) is a comprehensive behavioral treatment combining social skills training, peer generalization experiences, and individualized in vivo exposure for the treatment of social phobia in youth. SET-C results in positive treatment outcome and its effects are maintained at least 3 years later. In this investigation, maintenance of treatment gains 3, 4, and 5 years later was examined using a multidimensional assessment strategy consisting of self-report, parental report, clinician ratings, and direct behavioral assessment. Furthermore, the overall functioning of adolescents treated with SET-C 5 years earlier was compared with that of a group of adolescents who never suffered from psychological disorders. All posttreatment gains were maintained 5 years later, and the general functioning of SET-C treatment responders was not significantly different from those who never had a disorder. The data indicate that SET-C results in long-term positive effects for youth suffering from social phobia.
