Real-time detection of orientation during negative behavioral contrast with key pecking and a turning response

We developed a video system for real-time detection of a pigeon's orientation and for reinforcement of a “turning response.” Using this system, negative behavioral contrast was found across key-peck and turning responses. In addition, turning away from the pecking key was detected by the system just after presentation of the negative discriminative stimulus on the key. The results suggest that avoidance of the discriminative stimulus in the constant component, which has been regarded as a causal factor for negative contrast (additivity theory), is not the primary factor for negative behavioral contrast of pigeons' key pecking, but may account for negative local contrast.     

Video game violence: A review of the empirical literature

The popularity of video games, especially violent video games, has reached phenomenal proportions. The theoretical line of reasoning that hypothesizes a causal relationship between violent video-game play and aggression draws on the very large literature on media violence effects. Additionally, there are theoretical reasons to believe that video game effects should be stronger than movie or television violence effects. This paper outlines what is known about the relationship between violent video-game playing and aggression. The available literature on virtual reality effects on aggression is discussed as well. The preponderance of the evidence from the existing literature suggests that exposure to video-game violence increases aggressive behavior and other aggression-related phenomena. However, the paucity of empirical data, coupled with a variety of methodological problems and inconsistencies in these data, clearly demonstrate the need for additional research.     

Categorization of natural movements by pigeons: visual concept discrimination and biological motion

In three experiments, pigeons were exposed to a discriminated autoshaping procedure in which categories of moving stimuli, presented on videotape, were differentially associated with reinforcement. All stimuli depicted pigeons making defined responses. In Experiment 1, one category consisted of several different scenes of pecking and the other consisted of scenes of walking, flying, head movements, or standing still. Four of the 4 birds for which pecking scenes were positive stimuli discriminated successfully, whereas only 1 of the 4 for which pecking was the negative category did so. In the pecking-positive group, there were differences between the pecking rates in the presence of the four negative actions, and these differences were consistent across subjects. In Experiment 2, only the categories of walking and pecking were used; some but not all birds learned this discrimination, whichever category was positive, and these birds showed some transfer to new stimuli in which the same movements were represented only by a small number of point lights (Johansson's “biological motion” displays). In Experiment 3, discriminations between pecking and walking movement categories using point-light displays were trained. Four of the 8 birds discriminated successfully, but transfer to fully detailed displays could not be demonstrated. Pseudoconcept control groups, in which scenes from the same categories of motion were used in both the positive and negative stimulus sets, were used in Experiments 1 and 3. None of the 8 pigeons trained under these conditions showed discriminative responding. The results suggest that pigeons can respond differentially to moving stimuli on the basis of movement cues alone.     

Discrete‐trial training performance of behavior interventionists with autism spectrum disorder: A systematic replication and extension

Further research is needed on strategies to improve employment outcomes for individuals with autism spectrum disorder (ASD). We replicated and extended prior research by examining the acquisition, maintenance, and generalization of discrete‐trial training (DTT) performance of adults with ASD who were interested in careers as behavior technicians. Three participants received training on how to implement DTT with children and we assessed the maintenance and generalization of DTT performance in the absence of feedback. Results indicated that procedural integrity generalized across children and targets and maintained for 6 to 17 session days without feedback. Results have implications for the successful employment of individuals with ASD as behavior technicians and for future research on strategies to enhance their performance on the job.     

Mixing qualitative methods versus methodologies: A critical reflection on communication and power in inpatient care

This paper offers an illustrative example to demonstrate one way of combining qualitative methods. The context for the study was a UK inpatient psychiatric hospital. Data set one was collected from weekly ward rounds where inpatient staff met with autistic patients to review medication, listen to patient concerns and make plans or adjustments in light of this. Data set two was reflective discursive interviews with patients and staff. The research objective was to critically consider the potential reasons for discrepancies in dissatisfaction reports from patients in the interviews, compared to relative compliance exhibited by patients in the ward rounds. Utilising a video‐reflexive design and critical discursive psychology approach, both data sets were analysed together. It is possible to simultaneously analyse two different data sets, one naturally occurring and one researcher generated because of the epistemological congruence in the overall design. We have presented an argument for the benefits of mixing two qualitative methods, thereby extending the mixed‐methods evidence base beyond the traditional discussions of quantitative and qualitative paradigms.     

A mixed methods research study on the video‐based counselling method Marte Meo

Marte Meo is a video‐based counselling method founded by Maria Aarts in the Netherlands and now in worldwide use (Aarts, Aarts Production, 2008). Marte Meo has been adopted and put into practice by a large and diverse network of trained and certified counsellors across the world. It was invented, developed and spread by a vanguard of practising counsellors who have adapted it to a variety of contexts. This is a classic example of research and theory emerging from and following practice; we first need to synthesise the lessons the practitioners and families have learned. We need to better understand how it is implemented; how it is viewed by its practitioners and recipients; and the extent to which variability in implementation may be an asset or a drawback in the continuing evolution of the programme, and in any eventual attempt to document its effects. Therefore, the present article aimed to address this important and hitherto unexplored research topic of the Marte Meo method in counselling and to describe the current state of use of Marte Meo. How is Marte Meo used and applied in a counselling and therapeutic context? Who uses Marte Meo in professional practice? Which function and which meaning does Marte Meo have in general practice and especially in counselling and therapy? What are typical concerns, goals or areas of application? We report on an ongoing mixed methods research project which began in 2015. This paper focuses on the research methods. We will explain why an integrated exploratory sequential design (Cresswell, 2017) is best suited to our purposes. The exploratory sequential design of the Marte Meo project has five phases: as the first phase, we conducted a systematic literature review, analysing the status of existing research. The staged qualitative research consisted of designing, conducting and analysing semi‐structured interviews with parents and Marte Meo counsellors (phase 2), and then using that analysis to inform the design, the conduct and the analysis of videotaped observations of everyday situations in day‐care centres to examine the process and effects of Marte Meo interaction elements on children (phase 3). Combining these qualitative analyses then became the basis for the development of an online questionnaire that could enable us to collect quantitative data on the current use of Marte Meo in practice by experts (phase 4). This builds into the fifth phase in the final interpretation. One of the key findings of the qualitative parts is that Marte Meo is perceived as advantageous. The experts reported more joy and success in their work. In particular, in the pedagogical context, the daily, resource‐oriented ‘Marte Meo view’, which was sharpened by the training, seems to be essential, as it enables an awareness of the needs of the interaction partners and the beneficial interaction elements. Moreover, for some interviewees the use of Marte Meo does not seem to be limited to professional practice, but is expressed in a general humanistic attitude towards interpersonal relationships of all kinds. The quantitative survey has confirmed and supplemented these results. On the other hand, we found that Marte Meo is most often used in addition to the systemic approach. A later article will focus more on the findings. This article will conclude with a discussion of the advantages and disadvantages of the research design—concerning this special research project and concerning counselling research in general.

Teaching help‐seeking when lost to individuals with autism spectrum disorder

Deficits in safety skills and communication deficits place individuals with autism spectrum disorder (ASD) at an increased risk of danger. We used a multiple‐probe across‐participants design to evaluate the effects of video modeling and programming common stimuli to teach low‐ and high‐tech help‐seeking responses to children with ASD when lost. Participants acquired answering or making a FaceTime^® call and exchanging an identification card in contrived and natural settings. Responses generalized to novel community settings and maintained during a one‐ and two‐week follow‐up. Social validity measures showed that the procedures and outcomes of the study were acceptable to indirect and direct consumers, and immediate and extended community members. Implications are that children with ASD can effectively be taught both low‐ and high‐tech help‐seeking responses when lost.     

Teaching social perception skills to adolescents with autism and intellectual disabilities using video‐based group instruction

Few interventions focus on teaching social skills to adolescents with autism spectrum disorder (ASD) and intellectual disabilities (ID) that are consistently used during interactions with peers ( Carter et al., 2014). The present study evaluated the effects of video‐based group instruction (VGI) on the acquisition of social perception skills of five adolescents with ASD or ID in a public school setting. Social perception involves observing affective behaviors of others, discriminating relevant environmental stimuli, and differentially reinforcing the affective behavior of another person. Typically developing peers supported VGI implementation as social partners for participants. A multiple probe design across behaviors demonstrated the effectiveness of VGI for teaching social perception skills. Four of five participants acquired and maintained the targeted social perception skills, and we observed some transfer to a nontreatment setting. Results of this study suggest VGI may support the acquisition of social perception among adolescents with ASD or ID.
