Generate,maintain, manipulate? Exploring the multidimensional nature of motor imagery

Motor imagery (MI), the mental rehearsal of a motor task, is thought to be a synergistic interaction between processes that allow for the generation, maintenance, and manipulation, of motor images. While our understanding of the multidimensional nature of MI stems from research examining various methods to assess MI ability, limited research has been conducted employing multiple assessments across participants to probe the underlying dimensions of MI. Accordingly, the current study sought to explore the multidimensional nature of MI using an exploratory approach that would allow for the dimensions of imagery to be examined and linked to each assessment measure. Specifically, participants (N = 81) underwent a battery of MI-assessments (including questionnaires, mental chronometry, a hand laterality judgment task, and a MI-based learning task), and data was analyzed via principal component analysis (PCA). Three components resulted, which were named based on which outcome measures loaded on to the component: generation, maintenance, and manipulation of motor images. We further discuss a fourth component, named ‘temporal sequencing’ of motor images, identified via the initial component solution. Concordant with previous research, we highlight the importance of employing multiple measures when assessing imagery ability prior to its use in training. Notably, this work allowed us to link assessments of MI to the different dimensions of MI, informing on the nature of MI.     

Outcome Severity and Judgments of “Responsibility”: A Meta‐Analytic Review1

Research has provided mixed support for the hypothesis that when an incident results in a more severe outcome, more responsibility will be attributed to a potentially responsible actor. This paper uses the techniques of meta‐analysis to examine this literature. The results support the contention that people attribute greater responsibility for the outcome of a negative incident when that outcome is more severe than when the outcome is minor. The direction of this relationship is consistent across methodologies. However, the strength of the correlation varies depending on which type of judgment participants are asked to make. Because many of these variables are tied to legal concepts, the results are discussed in the context of the expectations of the legal system regarding the impact of outcome severity on each variable.     

Causal judgement from information about outcome magnitude

Information was presented in which a candidate cause was either present or absent, and the outcome variable (number of spots on a patient's skin) could take any of four nonzero values. It was found that cause-absent information carried greater weight than cause-present information. This is contrary to the usual finding for contingency information about binary outcome variables. Judgement was influenced more by extreme values of the outcome variable, and larger outcome values tended to have more effect on judgements than smaller outcome values. The hypothesis that participants compute linear correlation is disconfirmed by these results. Instead, the results show that participants focus disproportionate attention on some kinds of events and neglect others.     

A Multilevel Multivariate Analysis of Academic Performances in College Based on NCAA Student-Athletes

This is an application of contemporary multilevel regression modeling to the prediction of academic performances of 1st-year college students. At a first level of analysis, the data come from N > 16,000 students who were college freshman in 1994–1995 and who were also participants in high-level college athletics. At a second level of analysis, the student data were related to the different characteristics of the C = 267 colleges in Division I of the NCAA. The analyses presented here initially focus on the prediction of freshman GPA from a variety of high school academic variables. The models used are standard multilevel regression models, but we examine nonlinear prediction within these multilevel models, and additional outcome variables are considered. The multilevel results show that (a) high school grades are the best available predictors of freshman college grades, (b) the ACT and SAT test scores are the next best predictors available, (c) the number of high school core units taken does not add to this prediction but does predict credits attained, (d) college graduation rate has a second-level effect of a small negative outcome on the average grades, and (e) nonlinear models indicate stronger effects for students at higher levels of the academic variables. These results show that standard multilevel models are practically useful for standard validation studies. Some difficulties were found with more advanced uses and interpretations of these techniques, and these problems lead to suggestions for further research.     

Cognitive and affective variables as predictors of life satisfaction

This work shows the association between personality variables, such as cognitive and affective variables, and psychological adjustment, such as life satisfaction and depressive symptoms. Accordingly, this study assessed the role of outcome expectancies (optimism and pessimism) and affectivity (positive and negative affect) as a predictors of life satisfaction and depressive symptoms. A total of 458 students from the University Rovira i Virgili completed the scales LOT-R, PANAS, the Satisfaction with Life Scale and BDI. Path analysis results suggest that affectivity variables are more important to predict life satisfaction and depressive symptoms than outcome expectancies. Implications for future research are discussed.     

Differential Effectiveness of Behavioral Parent-Training and Cognitive-Behavioral Therapy for Antisocial Youth: A Meta-Analysis

Extended the findings from previous meta-analytic work by comparing the effectiveness of behavioral parent-training (BPT) and cognitive-behavioral therapy (CBT) for youth with antisocial behavior problems. Youth demographic variables were also examined as potential moderators of the effectiveness of these 2 types of interventions. Thirty BPT studies and 41 CBT studies met inclusion criteria for this meta-analysis. The weighted mean effect size (ES) for all interventions was 0.40. Youth age was found to moderate the outcome of the 2 interventions, with BPT having a stronger effect for preschool and school-aged youth and CBT having a stronger effect for adolescents. The results also indicate that there may be systematic differences in the outcomes associated with BPT and CBT when the setting of the intervention is considered, suggesting the need to carefully consider the effect of setting in future research. This study also highlights the need for outcome research dealing with more diverse populations and the better classification of research participants on different developmental trajectories of antisocial behavior.     

Sleep-related improvements in motor learning following mental practice

A wide range of experimental studies have provided evidence that a night of sleep may enhance motor performance following physical practice (PP), but little is known, however, about its effect after motor imagery (MI). Using an explicitly learned pointing task paradigm, thirty participants were assigned to one of three groups that differed in the training method (PP, MI, and control groups). The physical performance was measured before training (pre-test), as well as before (post-test 1) and after a night of sleep (post-test 2). The time taken to complete the pointing tasks, the number of errors and the kinematic trajectories were the dependent variables. As expected, both the PP and the MI groups improved their performance during the post-test 1. The MI group was further found to enhance motor performance after sleep, hence suggesting that sleep-related effects are effective following mental practice. Such findings highlight the reliability of MI in learning process, which is thought consolidated when associated with sleep.     

Reporting Ethics Committee Approval in Public Administration Research

While public administration research is thriving because of increased attention to social scientific rigor, lingering problems of methods and ethics remain. This article investigates the reporting of ethics approval within public administration publications. Beginning with an overview of ethics requirements regarding research with human participants, I turn to an examination of human participants protections for public administration research. Next, I present the findings of my analysis of articles published in the top five public administration journals over the period from 2000 to 2012, noting the incidences of ethics approval reporting as well as funding reporting. In explicating the importance of ethics reporting for public administration research, as it relates to replication, reputation, and vulnerable populations, I conclude with recommendations for increasing ethics approval reporting in public administration research.     

Imagery ability classification: Commentary on «Kinaesthetic imagery ability moderates the effect of an AO+MI intervention on golf putt performance: A pilot study» by McNeill et al. (2020)

McNeill et al. (2020) recently published a study that first aimed to assess the effect of a combination of motor imagery (MI) and action observation (AO) on golf putt performance and then to determine if the evolution of this performance could be moderated by participants’ kinesthetic imagery ability. To assess golfers’ MI ability, the authors used the third version of the Movement Imagery Questionnaire. Participants notably self-estimated their kinesthetic MI ability by using a Likert-type scale, with scores ranging from 1 “very difficult to feel” to 7 “very easy to feel”. Athletes were categorized as either “poor” or “good” kinesthetic imagers, with mean scores of 4.93 and 6.63, respectively, in the intervention groups. Although a similar categorization procedure had previously been used in the literature for “good imagers”, the mean scores for “poor” imagers were much higher than those noted in previous studies evaluating the effect of MI ability on motor accuracy. Moreover, the low number of participants in the intervention group (n = 22) meant that participants were considered “poor” imagers even though their mean scores corresponded to “quite easy to feel” kinesthetic images of movements. This could notably explain the lack of differences between “poor” and “good” imagers in terms of putting performance in the intervention group. Despite these methodological limitations, the results of McNeill et al.‘s study show promising evidence for the efficacy of an AO plus MI intervention in relation to putting performance and should lead to further investigations. We suggest that research in the area of motor imagery ability include larger samples to explore, in individuals with very low imagery ability scores, the effects of the combination of AO and MI on motor performance.     

Dimensions of verbal denial in myocardial infarction: Correlates to 3 denial scales

The concept of denial in medical patients was reviewed, and problems in the past research on denial was noted. A questionnaire developed to assess different aspects of denial in myocardial infarction was tested in a group of 367 patients. A factor analysis of the questionnaire gave 3 independent factors, termed Denial of Illness, Denial of Impact, and Suppression. This finding gave support to the model that guided the construction of the questionnaire, and also casted some doubt on the validity of using either single specific or global criteria in assessing denial. Multiple regression analyses, including a series of medical, psychological and social variables, showed that social desirablity and external health locus of control contributed to the prediction of high scores on all 3 scales. Denial of Illness was furthermore associatd with less previous cardiac disease and a less severe index MI, whereas Denial of Impact was related to indicators of more optimistic attitudes. Suppression was related to indicators of lower socio-economic status and less cardiac health knowledge. The 3 scales should be further examined in relation to outcome after a myocardial infarction.     

Using motivational interviewing as a supplement to obesity treatment: a stepped-care approach.

OBJECTIVE: This investigation was designed to improve behavioral weight loss program (BWLP) treatment outcomes by providing stepped care (SC) to individuals experiencing difficulties with weight loss during treatment. SC entails transition to more intensive treatments when less intensive treatments fail to meet treatment goals. In a BWLP, motivational interviewing (MI) may increase participants' motivation toward behavioral change and thus complement the acquisition of behavioral change skills. It was hypothesized that BWLP+SC (MI) participants (i.e., participants who failed to meet weight loss goals and received MI) would demonstrate superior treatment outcomes when compared with BWLP (SC matched) participants (i.e., participants who failed to meet weight loss goals but did not receive MI). DESIGN: Fifty-five obese, sedentary adults were randomly assigned to a BWLP+SC or a BWLP. MAIN OUTCOME MEASURES: Changes in weight, cardiorespiratory fitness, self-reported physical activity, and diet (i.e., calories, percentage daily intake of fat, protein, and carbohydrates) in response to treatment were assessed. RESULTS: Participants significantly decreased their weight, increased physical activity/fitness, and improved dietary intake (ps<.05). BWLP+SC (MI) participants lost more weight and engaged in greater weekly exercise than BWLP (SC matched) participants who did not receive MI (ps<.05). CONCLUSION: For individuals experiencing weight loss difficulties during a BWLP, MI may have considerable promise.     

Review of studies evaluating psychotherapy in bulimia nervosa: the influence of research methods

The purpose of the study was to test if design and research methods of studies predict outcome results of bulimia nervosa. Fifty-seven articles on outcome of bulimia nervosa were found through MEDLINE and PSYCHINFO databases and 25 were included in the statistical analysis. Percentages of patients with a good outcome ranged from 24% to 74% with a mean of 51.1%. The variables best predicting outcome were time to follow-up and number of symptoms evaluated in definition of good outcome whereas dropout, design of studies, treatments, and sample characteristics did not predict significantly. The implications of these findings are discussed.

Predicting outcome of insanity acquittees released to the community

This research developed a model for forensic release decisions that incorporated actuarial and psychiatric predictors. The model was based on research that compared 127 insanity acquittees in the State of Maryland with a matched control group of 127 convicted felons and a comparison group of 135 mentally disordered prison transfers. The three cohorts were followed for an average of 10 years after release from hospital or prison. Findings on two outcome indicators are reported in this article: rearrests within 5 years after release and overall functioning in the community during 2½ years after release. Discriminant analysis was performed on the outcome variable of rearrest; it was found to accurately predict the outcome of 75% of the subjects with the following six variables: adjustment in hospital, clinical assessment of hospital staff, Global Assessment Scale score at release, functioning prior to instant offense, heroin addiction, and birth order. A second discriminant analysis identified seven variables that accurately predicted the overall functioning of 80.4% of the insanity acquittees.     

The Effect of Negotiator Creativity on Negotiation Outcomes in a Bilateral Negotiation

This study examined creative negotiators to determine if they are able to achieve more successful outcomes in a negotiation context with integrative potential. Creativity scores were obtained from 70 participants, who performed a 2-party, multi-issue negotiation in 35 dyads. This negotiation led to economic and relational negotiation outcomes. The use of creative skills by negotiators was hypothesized to positively affect both classes of negotiation outcomes. Results indicated no significant effect of negotiators' creativity on economic negotiation outcomes. A negative effect of negotiators' creativity on relational negotiation outcome for the buyer was observed. For the relational negotiation outcome of the seller, the same negative tendency was observed, though no significant effect of negotiators' creativity. These findings extend the understanding of the relationship between negotiators' creativity and negotiation outcomes, which is highly underemphasized in current research. Further research should identify which aspects of creativity are crucial to negotiators and determine how they can be adequately measured. The issue of interaction between negotiators' creativity and situational variables should also be addressed, as it likely determines the effect of creativity on negotiation outcomes.     

Motor learning without physical practice: The effects of combined action observation and motor imagery practice on cup-stacking speed

In this study we explored training effects for combined action observation and motor imagery (AO + MI) instructions on a complex cup-stacking task, without physical practice. Using a Graeco-Latin Square design, we randomly assigned twenty-six participants into four groups. This counterbalanced the within-participant factor of practice condition (AO + MI, AO, MI, Control) across four cup-stacking tasks, which varied in their complexity. On each of the three consecutive practice days participants experienced twenty trials under each of the three mental practice conditions. On each trial, a first-person perspective video depicted bilateral cup-stacking performed by an experienced model. During AO, participants passively observed this action, responding only to occasional colour cues. For AO + MI, participants imagined performing the observed action and synchronised their concurrent MI with the display. For MI, a sequence of pictures cued imagery of each stage of the task. Analyses revealed a significant main effect of practice condition both at the ’surprise’ post-test (Day 3) and at the one-week retention test. At both time points movement execution times were significantly shorter for AO + MI compared with AO, MI and the Control. Execution times were also shorter overall at the retention compared with the post-test. These results demonstrate that a complex novel motor task can be acquired without physical training. Practitioners can therefore use AO + MI practice to supplement physical practice and optimise skill learning.     

The importance of contextual variables when judging fairness: An examination of counterfactual thoughts and fairness theory

This research empirically examines the underlying mechanisms of fairness theory (  and ), namely counterfactual thought processes. Study 1 used a policy-capturing design to examine the relative importance of contextual variables in predicting counterfactual thoughts and fairness perceptions. Study 2 utilized a between-subjects design and asked participants to generate their own counterfactuals in response to an unfortunate event. Results of both studies showed that fairness perceptions are influenced by contextual variables (i.e., outcome severity, target knowledge and expertise, sin of commission vs. omission) and counterfactual thinking. Counterfactual thoughts partially mediated the effects of contextual variables and fairness perceptions in Study 1. Exploratory analyses from Study 3 revealed that the measurement of counterfactual thoughts (frequency vs. strength) may capture different underlying constructs. Implications are discussed.     

Predictors of suicidal thoughts: Mood instability versus neuroticism

The personality trait neuroticism predicts depression and suicidal thoughts. Neuroticism is also linked to mood instability (MI)¹ that is common in patients with depression. This study investigated (a) whether MI predicts suicidal thoughts in depressed patients and (b) the relationship of MI to neuroticism. All 129 patients with Major Depression (MINI interview) were assessed on MI (Affective Lability Scale), neuroticism (Short Eysenck Neuroticism Scale), depression (Beck Depression Inventory), and suicidal thoughts (Beck Scale for Suicidal Ideation). Participants also completed the Perceived Stress Scale, Mood Disorder Questionnaire and five clinical questions on MI. Factor analysis of the Eysenck Neuroticism Scale revealed unstable moods as one of three main factors. Only depression severity and MI predicted suicidal thoughts once other variables including neuroticism were controlled. Mediation analyses showed that MI mediated the relationship between neuroticism and suicidal thoughts. These results suggest that MI as measured by the Affective Lability Scale typifies the type of depression that predicts suicidal thoughts and that MI may be more directly associated with suicidal thoughts than neuroticism. This demonstrates the clinical value of assessing MI rather than neuroticism in the treatment of patients with depression with suicidal thoughts.     

Understanding Motivational Interviewing Effectiveness: Contributions From Rogers' Client-Centered Approach

The object of this article is to gain a better understanding of motivational interviewing (MI) effectiveness using the framework of Rogers' approach. Examining MI's common points and differences with Rogers' client-centered therapy can make it possible to identify some of MI's active ingredients and its underlying process of effectiveness, especially related to MI relational component. In return, MI, a strongly evidence-based approach, could provide empirical basis and support of effectiveness for Rogers' client-centred therapy. The review of literature on Rogers' therapy and MI shows strong links between the two approaches. MI applies most of Rogers' therapy attitudes and techniques such as empathy, acceptance, autonomy support, collaborative style, and confidence in the client's ability to change. The article further presents a review of research data related to the therapeutic effects of each of these attitudes. Finally, implications for clinical practice and further research are discussed. MI and Rogers' client-centered approach have much to offer each other. The strong process and outcome research tradition in MI could bring about evidence on Rogers' therapy effectiveness. Rogers' work provides a testable theoretical basis for the mechanisms of MI effectiveness. Further MI research should operationalize more than just empathy in the relational component.
