The relationship between shame and perceived biological origins of mental illness among South Asian and white American young adults

Mental illness (MI) affects one in four people in their lifetime and a failure to seek help for MI can have grave consequences. To decrease stigma and increase help seeking, prior campaigns have promoted the biological origins of MI. Even though some research supports the efficacy of this approach, other research does not. We propose cultural differences as a partial explanation for these inconsistent results. The current study assessed ethnic differences in the relationship between perceived causes of MI, shame associated with MI and perceived family support for help seeking. White and South Asian American (SAA) undergraduate students completed an online survey (n = 177). Results indicated that SAAs were significantly more likely than whites to perceive character deficits as the cause of MI. Further, among those who had sought help for MI, ethnic differences emerged in perceptions of MI based on perceived cause. SAAs who believed that MI had biological origins perceived more shame and less family support for seeking help compared to SAAs who believed MI was due to character deficits. The converse was true for whites – those who believed that MI had biological origins perceived less shame and more family support for help seeking compared to whites who believed MI was due to character deficits. The results of the current study illuminate the role that culture plays in perceptions of MI. Further, these results have implications for interventions targeting South Asian populations and for mental health outreach in general.     

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.     

Career counseling meets motivational interviewing: A sequential analysis of dynamic counselor–client interactions

Motivational Interviewing (MI) is a client-centered communication style with the aim to resolve client ambivalence within a change-related counseling. Its potential benefit for career counseling has been discussed by several scholars but no empirical research has investigated MI in this context so far. The current study used process measures from MI to investigate dynamic interactions within a career counseling intervention. Overall, we analyzed two videotaped sessions of 14 unique counselor–client dyads. Verbal behavior of counselors and clients were coded with two observational coding schemes from MI (one for counselors and one for clients, respectively). Behavior profiles of counselors were compared with benchmarks of good MI. Furthermore, client verbal ambivalence was compared between sessions. Finally, we conducted lag sequential analyses to analyze temporal dynamics between counselor behavior and immediate client verbal responses across N = 6883 behavioral events. Our results showed, first, behavior profiles of career counselors did significantly differ from recommended counseling benchmarks of good MI practice. Second, as assumed on the basis of past studies, client ambivalence decreased across sessions. Third, MI consistent counselor behaviors showed a positive sequential association with client positive career talk, whereas MI inconsistent counselor behaviors showed the reverse pattern. Our results suggest that counseling behaviors recommended from MI are facilitating career interventions. We discuss how trainings in MI could amend career counseling interventions and provide ethical implications when integrating MI into career counseling programs.     

Are Fast Complex Movements Unimaginable? Pupillometric Studies of Motor Imagery in Expert Piano Playing

Motor imagery (MI; mental simulation of actions) shares certain mental representations and processes with executed movement (ME). This neurocognitive overlap between MI and ME may explain why the systematic use of MI improves skilled performance in numerous domains. Unfortunately, the attentional mechanisms underlying MI remain unresolved. Therefore, the present studies investigated the role of attentional effort (as measured by pupil dilation) in MI. We evaluated the effects of movement complexity and speed on expert pianists' pupil dilation as they physically executed and used MI to perform easy/complex and slow/fast music phrases. Results revealed that easy movements required similar levels of attentional effort during MI and ME. However, during complex movements performed at a fast speed, the correspondence between execution and imagery of movement was disrupted.     

Time–Frequency Cross Mutual Information Analysis of the Brain Functional Networks Underlying Multiclass Motor Imagery

To study the physiologic mechanism of the brain during different motor imagery (MI) tasks, the authors employed a method of brain-network modeling based on time–frequency cross mutual information obtained from 4-class (left hand, right hand, feet, and tongue) MI tasks recorded as brain–computer interface (BCI) electroencephalography data. The authors explored the brain network revealed by these MI tasks using statistical analysis and the analysis of topologic characteristics, and observed significant differences in the reaction level, reaction time, and activated target during 4-class MI tasks. There was a great difference in the reaction level between the execution and resting states during different tasks: the reaction level of the left-hand MI task was the greatest, followed by that of the right-hand, feet, and tongue MI tasks. The reaction time required to perform the tasks also differed: during the left-hand and right-hand MI tasks, the brain networks of subjects reacted promptly and strongly, but there was a delay during the feet and tongue MI task. Statistical analysis and the analysis of network topology revealed the target regions of the brain network during different MI processes. In conclusion, our findings suggest a new way to explain the neural mechanism behind MI.     

How does motor imagery speed affect motor performance times? Evaluating the effects of task specificity

The present experiment investigated whether motor imagery (MI) performed at a faster speed might influence the actual motor performance duration by comparing real‐time vs. fast MI of different finger movement sequences. Forty‐eight participants were either asked to do real‐time or fast MI practice of simple 8‐digit (unimanual), complex 8‐digit (bimanual), and long (16‐digit) finger movement sequences. The main findings revealed that both fast and real‐time MI resulted in actual speed gains in all experimental conditions, hence suggesting that performing fast MI did not systematically provide additional benefits as compared to real‐time MI. Interestingly, the results suggested that the speed at which movements were performed following an increase in MI speed was selectively influenced by the complexity of the task. MI training at higher speed seemed to be more effective in changing complex motor sequences compared with real‐time MI. Practical implications in motor learning and rehabilitation are also discussed.

Impact of Neurologic Deficits on Motor Imagery: A Systematic Review of Clinical Evaluations

Motor imagery (MI, the mental representation of an action without engaging in its actual execution) is a therapeutically relevant technique to promote motor recovery after neurologic disorders. MI shares common neural and psychological bases with physical practice. Interestingly, both acute and progressive neurologic disorders impact brain motor networks, hence potentially eliciting changes in MI capacities. How experimental neuroscientists and medical practitioners should assess and take into account these changes in order to design fruitful interventions is largely unresolved. Understanding how the psychometric, behavioral and neurophysiological correlates of MI are impacted by neurologic disorders is required. To address this brain-behavior issue, we conducted a systematic review of MI data in stroke, Parkinson’s disease, spinal cord injury, and amputee participants. MI evaluation methods are presented. Redundant MI profiles, primarily based on psychometric and behavioral evaluations, emerged in each clinical population. When present, changes in the psychometric and behavioral correlates of MI were highly congruent with the corresponding motor impairments. Neurophysiological recordings yielded specific changes in cerebral activations during MI, which mirrored structural and functional reorganizations due to neuroplasticity. In this view, MI capacities may not be deteriorated per se by neurologic diseases resulting in chronic motor incapacities, but adjusted to the current state of the motor system. Literature-driven orientations for future clinical research are provided.     

The impact of confidence in evaluating on discounting: A missing information context example

• Consumers often use coping mechanisms to aid in processing imperfect information about products when making choices. Specifically, a common evaluation processing pattern of uncertainty detection, uncertainty resolution and discounting behaviour (U–R–D) has been observed, particularly in studies involving missing information (MI). When consumers detect MI (uncertainty), they often discount the MI alternatives unless confidently held inferences are formed to reduce uncertainty (resolution), which attenuates discounting (U–R–D). This paper proposes consumers' overall confidence in evaluating (CE) plays a role in the U–R–D processing pattern. In MI contexts, inferences formed to fill‐in MI may also increase overall CE which may have an effect on discounting that is separate and distinct to that of the formation of confidently held inferences. While the impact on discounting of inferences formed to fill in MI is only relevant in MI contexts, the impact of the more encompassing CE variable may impact non‐MI contexts (affected by non‐MI uncertainty) as well. The concept of CE broadens the scope of the U–R–D processing pattern commonly observed in MI contexts to other evaluation contexts. Two studies demonstrate the role of CE in the U–R–D evaluation process (in MI contexts). A model proposes more general interactive effects of sources of uncertainty, and uncertainty detection and resolution on CE and discounting.

Characterizing linguistic structure with mutual information

We explore mutual information (MI) as a means of characterizing linguistic statistical structure. The MI between two linguistic tokens x and y is the degree to which seeing x helps us anticipate the occurrence of y. We computed MI between words in 595 samples of written text in 25 languages. Our analyses indicate that MI dependencies do not extend beyond a range of five words. Moreover, the similarity between MI profiles of different languages was used to cluster the languages. These results are discussed in terms of a putative link between short‐term memory and linguistic structure and the further utility of MI in terms of characterizing the latter.     

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.     

Motor imagery and ‘placebo-racket effects’ in tennis serve performance

ObjectivesThis study aimed at confirming whether Motor Imagery (MI) enhances tennis serve performance, and determining whether a placebo condition could affect the beneficial effects of MI.DesignThis study used a 3 × 2 factorial design. Three groups of tennis players were compared in service performance outcomes before and after a training session.MethodsTwenty-two tennis players were assigned into three groups: a control (C) and two experimental groups subjected to a similar MI intervention, one group using their regular own racket (MI group) while the other used a placebo racket (P group).ResultsAnalyses of Covariance revealed no significant group difference when comparing serve velocity after training session, but MI training improved serve accuracy and regularity. Combining placebo racket with MI further resulted in greater serve accuracy score as compared to MI alone. Players' perception of their serve quality improved after MI, and this effect was reinforced in the P group.ConclusionThese findings revealed that MI may be useful to achieve peak performance, and that the implement placebo effect might be a factor in sport performance, hence promoting the beneficial effects of alternative methods to improve tennis serve performance.     

Self-modelled versus skilled-peer modelled AO+MI effects on skilled sensorimotor performance

Action observation (AO) and motor imagery (MI) are simulation states that have been demonstrated to independently enhance motor skill performance. Historically, AO and MI were examined in isolation from one another; however recent neurophysiological and behavioural evidence indicates that using MI during AO (AO+MI) may be more potent at enhancing performance than either simulation state alone. The AO component of AO+MI is typically delivered via a self-modelled or peer-skilled model paradigm, via an observation video. The purpose of the proposed study is to further examine the implementation of AO+MI states by directly comparing the effectiveness of self-modelled AO+MI with peer-skilled modelled AO+MI to augment performance on a golf putting task with a sample of 56 skilled golfers. Our primary hypothesis predicts that skilled participants who engage with a self-modelled intervention will improve their performance more than those engaging with a peer-skilled model intervention. This hypothesis is predicated on the idea that self-modelling will be used in the context of performers’ existing mental representation and will facilitate improved performance, whereas the peer modelling may destabilize skilled performers’ existing mental representation.     

Smoking following myocardial infarction: a critical review of the literature

This paper critically reviews the available research on the effects of smoking cessation following acute myocardial infarction (MI). Studies that have examined the rate of smoking cessation following an MI indicate that approximately 1/3 to 1/2 of the smokers who suffer from MI subsequently reduce or quit smoking. Furthermore, studies that have examined subsequent mortality and morbidity suggest that individuals who quit smoking following MI exhibit lower mortality and morbidity than those who continue to smoke. It is argued that past studies may have overestimated post-MI smoking cessation rates, and by failing to control for a priori differences between quitters and continuing smokers (e.g., MI severity) may have underestimated the negative effects of smoking following MI. Suggestions for future research are proposed.     

Investigating the dose-response relationship between motor imagery and motor recovery of upper-limb impairment and function in chronic stroke: A scoping review

The recovery of upper-limb impairment and dysfunction post-stroke is often incomplete owing to the limited time in therapy focused on upper-limb recovery and the severity of the impairment. In these cases, motor imagery (MI) may be used as a precursor to physical therapies to initiate rehabilitation early on when it would be otherwise impossible to engage in therapy, as well as to increase the dose of therapy when MI is used in adjunct to physical therapy. While previous reviews have shown MI to be effective as a therapeutic option, disparity in findings exists, with some studies suggesting MI is not an effective treatment for post-stroke impairment and dysfunction. One factor contributing to these findings is inconsistency in the dose of MI applied. To explore the relationship between MI dose and recovery, a scoping review of MI literature as a treatment for adult survivors of stroke with chronic upper-limb motor deficit was performed. Embase, Medline and CINHAL databases were searched for articles related to MI and stroke. Following a two-phase review process, 21 papers were included, and data related to treatment dose and measures of impairment and function were extracted. Effect sizes were calculated to investigate the effect of dosage on motor recovery. Findings showed a high degree of variability in dosage regimens across studies, with no clear pattern for the effect of dose on outcome. The present review highlights the gaps in MI literature, including variables that contribute to the dose-response relationship, that future studies should consider when implementing MI.     

Effect of imagined movement speed on subsequent motor performance

Researchers realize that motor imagery (MI) duration is closely linked to actual motor action duration. In 2 experiments, the authors investigated the effect of changing MI speed on actual movement duration over a 3-week training period. Experiment 1 involved 2 series of body movements that 24 participants mentally performed faster or slower than their actual execution speeds. The fast MI group's actual times decreased on subsequent performance. Participants in Experiment 2 were 21 skilled athletes who increased (decreased) their well-rehearsed actual movement times after MI training at a slow (fast) speed. The effect was task-related, however: MI affected only self-initiated movement. The effect of MI on actual speed execution supports the ideomotor theory because anticipation of sensory consequences of actions is mentally represented.     

A Test of the Validity of the Motivational Interviewing Treatment Integrity Code

To evaluate the Swedish version of the Motivational Interviewing Treatment Code (MITI), MITI coding was applied to tape‐recorded counseling sessions. Construct validity was assessed using factor analysis on 120 MITI‐coded sessions. Discriminant validity was assessed by comparing MITI coding of motivational interviewing (MI) sessions with information‐ and advice‐giving sessions as well as by comparing MI‐trained practitioners with untrained practitioners. A principal‐axis factoring analysis yielded some evidence for MITI construct validity. MITI differentiated between practitioners with different levels of MI training as well as between MI practitioners and advice‐giving counselors, thus supporting discriminant validity. MITI may be used as a training tool together with supervision to confirm and enhance MI practice in clinical settings. MITI can also serve as a tool for evaluating MI integrity in clinical research.     

Computerized adaptive testing: A mixture item selection approach for constrained situations

In computerized adaptive testing (CAT), traditionally the most discriminating items are selected to provide the maximum information so as to attain the highest efficiency in trait (θ) estimation. The maximum information (MI) approach typically results in unbalanced item exposure and hence high item‐overlap rates across examinees. Recently, Yi and Chang (2003) proposed the multiple stratification (MS) method to remedy the shortcomings of MI. In MS, items are first sorted according to content, then difficulty and finally discrimination parameters. As discriminating items are used strategically, MS offers a better utilization of the entire item pool. However, for testing with imposed non‐statistical constraints, this new stratification approach may not maintain its high efficiency. Through a series of simulation studies, this research explored the possible benefits of a mixture item selection approach (MS‐MI), integrating the MS and MI approaches, in testing with non‐statistical constraints. In all simulation conditions, MS consistently outperformed the other two competing approaches in item pool utilization, while the MS–MI and the MI approaches yielded higher measurement efficiency and offered better conformity to the constraints. Furthermore, the MS–MI approach was shown to perform better than MI on all evaluation criteria when control of item exposure was imposed.     

Generating and sharing of market intelligence in sales teams: an economic social network perspective

In this research, we take a multimethod approach to shed light on the potential costs to sales teams that generate and share market intelligence (MI). First, we introduce an analytical model to propose the respective levels of effort that sales managers, experts, and team members spend generating and sharing MI. To test our propositions, we utilize social network data from 40 independent, business-to-business (B2B) sales teams, representing 287 salespeople. Interestingly, our results support the premise that team members become dependent (reduce MI efforts) when their sales manager or team expert shares MI among the team. We term this a “sharing tax” that sales managers and team experts pay when they share MI. Consequently, sales managers demonstrate greater MI-generation efforts the more they share MI. We also find that experts who share more (less) also show greater (lesser) MI-generation efforts, but only for teams where sales managers share low (high) levels of MI. In summary, our research innovatively conducts an empirical test of the Nash Equilibrium pattern of sales team effort to show that two critical team members, the sales manager and expert, are at a disadvantage when they share valuable MI.     

A Determinable-Based Account of Metaphysical Indeterminacy

Many phenomena appear to be indeterminate, including material macro-object boundaries and certain open future claims. Here I provide an account of indeterminacy in metaphysical, rather than semantic or epistemic, terms. Previous accounts of metaphysical indeterminacy (MI) have typically taken this to involve its being indeterminate which of various determinate (precise) states of affairs obtain. On my alternative account, MI involves its being determinate (or just plain true) that an indeterminate (imprecise) state of affairs obtains. I more specifically suggest that MI involves an object's (i) having a determinable property, but (ii) not having any unique determinate of that determinable. I motivate the needed extension of the traditional understanding of determinables, then argue that a determinable-based account of MI accommodates, in illuminating fashion, both ‘glutty’ and ‘gappy’ cases of MI, while satisfactorily treating concerns about MI stemming from Evans’ argument and the problem of the many.     

Motivational interviewing for employment: An exploration of practitioner skill and client change talk

Motivational interviewing (MI) is an evidenced-based approach for building and strengthening motivation for change. The effect of MI training on practitioner conversations with unemployed clients within a government work and income service was evaluated using a mixed-method approach, comprising a multiple-baseline across practitioner (n = 5) design and a pre/post quasi-experimental design. After workshop MI training, practitioners demonstrated greater MI skills in conversations with clients, and MI skills were maintained during the period of post-workshop feedback and coaching. There was also more change talk spoken by clients in conversations that occurred post-MI workshop training compared to pre-training, suggesting increased motivation for change.
