The measurement of left—right asymmetries in the Simon effect: A fine-grained analysis

The spatial Simon effect is often asymmetric, being greater on one side than on the other. To date, not much attention has been paid to these asymmetries, and explanations of the Simon effect do not take them into account. In the present article, we attempt to clarify the statistical implications of the asymmetries so as to provide a useful tool for future empirical investigation. Starting with examples from our laboratory and previous well-known studies, we point out the consequences of ignoring the asymmetries in the Simon effect. We suggest an alternative data analysis that might render the results clearer. Finally, through a comparison of left- and right-handed subjects, we demonstrate that asymmetries in the Simon effect are linked to the lateralization of processes involved in the Simon task—that is, attention and response selection. This approach provides a strong argument against collapsing data from the two sides to measure the Simon effect.     

Facilitating ambulation and activity in persons with profound multiple disabilities through a visual orientation system

A visual orientation system was employed to help two adults with profound multiple disabilities ambulate to programmed activity destinations and carry out familiar activities. The system consisted of a portable control device and light sources. The person participating in experiment 1 was to operate the control device for activating the programmed destinations (and turning on light sources showing the way to them). The person participating in experiment 2 did not need to operate the control device; this activated each programmed destination automatically. A new destination was activated after a preset time had elapsed from the person reaching the previous destination. Results indicated that both persons used the visual orientation system successfully and thus could reach the destinations and carry out activities on their own. General implications of the findings are discussed. © 1998 John Wiley & Sons, Ltd.     

Uncovering the Motivational Core of Traits: The Case of Conscientiousness

Knowledge of the motivational bases of conscientiousness would be crucial for disentangling competing explanations about the processes underlying this trait. Thereby, building on the results of a previous investigation identifying 21 goal classes connected to conscientiousness, we performed three studies aimed at clarifying the full spectrum of goals and motives underlying this trait. In Study 1 (N = 299), we conceptually replicated the original associations between goal classes and conscientiousness poles, and we identified nine goal classes that individuals ascribe to conscientious profiles more than to other profiles. In Study 2 (N = 329), we examined the associations between the subjective importance of conscientious and unconscientious goal classes and personality traits, as well as the role of goals for the desire to change one's conscientiousness. In Study 3 (N = 432), we developed a 72-item assessment of nine goal classes and explored their connections with the most important facets of conscientiousness, self-control, future orientation, and the consideration of future consequences, using network analysis. We discuss the relevance of our results for research on conscientiousness and its underlying processes. © 2020 European Association of Personality Psychology

How schoolchildren’s acceptance of self and others relate to their attitudes to victims of bullying

Previous research has indicated that harm to the mental health of children who are repeatedly victimised by their peers at school can be ameliorated through social or emotional support provided by other students. In this study we examined whether student provictim attitudes are related to more basic attitudes to self and attitudes to others. Measures of these attitudes were developed for use with children, and shown to be internally consistent and possess concurrent validity. Relations between these variables were then examined with a sample of Australian school children ( $N = 212$ ) aged between 9 and 14 years. Provictim attitudes correlated significantly ( $r = .55$ ) with acceptance of others, but not with acceptance of self ( $r = -.04$ ). Controlling for age and gender, multiple regression analyses confirmed these findings. Attitudes to victims were less positive for older students ( $r = -.22$ ). Gender differences, however, were not significant. These findings suggest that among schoolchildren self-acceptance is unrelated to positive attitudes towards victims, whereas acceptance of others has a moderately strong relation with provictim attitude. Implications for improving attitudes to victims among school children were examined.     

Effects of Language of Instruction on Response Accuracy and Challenging Behavior in a Child with Autism

Discrete trial training was delivered using English and Spanish languages to a student with autism from a Spanish-speaking family. An alternating treatments design was used to examine the effects of language of instruction on the child’s response accuracy and challenging behavior. More correct responses and fewer challenging behaviors occurred when instruction was delivered in Spanish compared to English. Results suggest that the language of instruction may be an important variable even when a student initially presents with very little spoken language and comparable scores on English and Spanish standardized language assessments.     

Use of Computer-Based Interventions to Teach Communication Skills to Children with Autism Spectrum Disorders: A Systematic Review

The purpose of this review is to provide a systematic analysis of studies involving the use of computer-based interventions (CBI) to teach communication skills to children with autism spectrum disorders (ASD). This review evaluates intervention outcomes, appraises the certainty of evidence, and describes software and system requirements for each included study. This review has three main aims: (a) to evaluate the evidence-base regarding CBI, (b) to inform and guide practitioners interested in using CBI, and (c) to stimulate and guide future research aimed at improving the efficiency and effectiveness of CBI in communication for individuals with ASD. Results suggest that CBI should not yet be considered a researched-based approach to teaching communication skills to individuals with ASD. However, CBI does seem a promising practice that warrants future research.     

Cognitive and neural determinants of response strategy in the dual-solution plus-maze task

Response strategy in the dual-solution plus maze is regarded as a form of stimulus-response learning. In this study, by using an outcome devaluation procedure, we show that it can be based on both action-outcome and stimulus-response habit learning, depending on the amount of training that the animals receive. Furthermore, we show that deactivation of the dorso-medial and the dorso-lateral striatum with Botulinum neurotoxin A, mimicked or abolished, respectively, the effects of practice on the sensitivity of the response strategy to outcome devaluation. These findings have relevant implications for the understanding of the learning mechanisms underlying different overt behaviors in this widely used maze task.     

Does how I look at what you're doing depend on what I'm doing?

Previous studies showed that people proactively gaze at the target of another's action by taking advantage of their own motor representation of that action. But just how selectively is one's own motor representation implicated in another's action processing? If people observe another's action while performing a compatible or an incompatible action themselves, will this impact on their gaze behaviour? We recorded proactive eye movements while participants observed an actor grasping small or large objects. The participants' right hand either freely rested on the table or held with a suitable grip a large or a small object, respectively. Proactivity of gaze behaviour significantly decreased when participants observed the actor reaching her target with a grip that was incompatible with respect to that used by them to hold the object in their own hand. This indicates that effective observation of action may depend on what one is actually doing, being actions observed best when the suitable motor representations may be readily recruited.
