Abstract

Chinese herbal medicine is effective in treating some addictions using, for example, aural acupuncture. Its application outside of China is limited due to a lack of clinical trials and ‘scientific’ evidence. U'finer™ is one of the first herbal remedies to undergo clinical trials, and is so far demonstrating a remarkable ability to improve brain function, restore physical health and enhance recovery from opiate addiction. The drug's pioneer Dr Wei Wang explains his methods and the drug's unique ability to treat the body and mind.

Abstract

Purpose

The purpose of this study is to examine how consumer personality trait impulsiveness influences trustworthiness evaluations of online-offers with different trust-assuring and trust-reducing elements by measuring the brain activity of consumers. Shoppers with high degrees of impulsiveness are referred to as hedonic shoppers, and those with low degrees are referred to as prudent consumers.

Design/methodology/approach

To investigate the differences between neural processes in the brains of hedonic and prudent shoppers during the trustworthiness evaluation of online-offers, the present study used functional magnetic resonance imaging (fMRI) and region-of-interest analysis to correlate neural activity patterns with behavioral measures of the study participants.

Findings

Drawing upon literature reviews on the neural correlates of both trust in online settings and consumer impulsiveness and using an experimental design that links behavioral and fMRI data, the study shows that consumer impulsiveness can exert a significant influence on the evaluation of online-offers. With regard to brain activation, both groups (hedonic and prudent shoppers) exhibit similar neural activation tendencies, but differences exist in the magnitude of activation patterns in brain regions that are closely related to trust and impulsiveness such as the dorsal striatum, anterior cingulate, the dorsolateral prefrontal cortex and the insula cortex.

Research limitations/implications

The data provide evidence that consumers within the hedonic group evaluate online-offers differently with regard to their trustworthiness compared to the prudent group, and that these differences in evaluation are rooted in neural activation differences in the shoppers’ brains.

Practical implications

Marketers need to be made aware of the fact that neurological insights can be used for market segmentation, because consumers’ decision-making processes help explain behavioral outcomes (here, trustworthiness evaluations of online-offers). In addition, consumers can learn from an advanced understanding of their brain functions during decision-making and their relation to personal traits such as impulsiveness.

Originality/value

Considering the importance of trust in online shopping, as well as the fact that personality traits such as impulsiveness influence the purchase process to a high degree, this study is the first to systematically investigate the interplay of online trustworthiness perceptions and differences in consumer impulsiveness with neuroscientific methods.

Abstract

Purpose

In the last 10 to 15 years, research studies have focused on the effects of differences across generations that result in differences in cultural expectations within the workplace (e.g. Arsenault, 2004). Different generations create shared attitudes to work and preferences for types of work which result in differences in their perception of, for instance, what makes a good leader or even the value of leadership within an organisation. While these generational differences are real, these analyses do not take into account differences that might result from the age, and therefore developmental stage, of the populations being assessed. The neuroscience literature clearly shows that there are maturational differences in the brain which are not complete until late teens to early 20s. It is therefore possible that some of the generational differences result from differences in processing ability resulting from structural immaturities in the brain. In particular, there are differences in the rate of maturation of areas of the brain related to reward sensitivity, threat sensitivity and regulation of behaviour which result in substantial differences in behaviour from adolescence through into adulthood. The purpose of this paper is to consider the effect of maturational changes in the brain on behaviours related to leadership and to outline ways in which these changes can be addressed in order to encourage young people to develop as leaders. This will include providing suitable experiences of leadership to encourage the faster development of the neural structures which underlie these capabilities.

Design/methodology/approach

Recent advances in neural imaging have resulted in a substantial increase in research investigating the development of the brain during adolescence. A literature review was conducted to find adolescent research that investigated decision making and risk taking. The data obtained were integrated and implications for leadership were drawn from an analysis of the resulting theoretical framework.

Findings

The research into decision-making processes in adolescents and younger adults points to a number of ways in which these differ from mature decision making. Younger people: (find it harder to inhibit behaviours) are more responsive to immediate reward; are more optimistic about the outcome of risky decisions; and are more responsive to social rewards (Jones et al., 2014). They also lack the experiences that adults use to distil the gist of a situation and therefore are more dependent on conscious, cost-benefit analysis of the outcome of decisions.

Practical implications

An understanding of the differences between adult and adolescent decision making points to the role of experience as a key factor in mature decision making. If adolescents are to make mature decisions, they have to be offered suitable challenges in safe environments from which they can gain expertise in leadership decision making. These can be designed to account for differences in sensitivity to reward and punishment in this group. In addition, young adults would benefit from learning the gist interpretations that have been extracted from situations by experienced leaders. This suggests that adolescents and adults would benefit from simulated leadership experiences and leadership mentoring.

Social implications

The Baby Boomer generation who currently hold many of the leadership positions in organisations are coming close to requirement. They will have to be replaced by members of Generation X and the Millennial Generation resulting in potentially younger leaders. In addition, flatter organisational structures that are currently being implemented in many organisations will require leadership at many more levels. Thus, we need to be able to develop leadership skills in a more diverse and younger section of society. Understanding how the brain develops can help us to design appropriate leadership experiences and training for this upcoming generation of young leaders.

Originality/value

Recent advances in neuroscience of adolescence provide a unique opportunity to bring new evidence to bear on our understanding of decision making in young adults. This provides practical implications for how to develop leadership within this group and to support them as they gain experience in this domain. The evidence also points to a benefit for the increased risk taking seen in adolescence since this leads to greater motivation to try new, and potentially risky, ventures. Through a better understanding of the differences in decision making, we can both help adolescents to develop more mature decision making faster while benefitting from the optimism of youth.

Abstract

Studies suggest deep brain stimulation (DBS) as a treatment modality for the refractory obsessive-compulsive disorder (OCD). It is unclear where to place the DBS. Various sites are proposed for placement with the ventral capsule/ventral striatum (VC/VS) among the most studied. Herein, we aim to summarize both quantitative Yale-Brown Obsessive-Compulsive Scale (YBOCS) data and qualitative descriptions of the participants' symptoms when given. A literature search conducted via PubMed yielded 32 articles. We sought to apply a standard based on the utilization of YBOCS. This yielded 153 distinct patients. The outcome measure we focused on in this review is the latest YBOCS score reported for each patient/cohort in comparison to the location of the DBS. A total of 32 articles were found in the search results. In total, 153 distinct patients' results were reported in these studies. Across this collection of papers, a total of 9 anatomic structures were targeted. The majority of studies showed a better response at the last time point as compared to the first time point. Most patients had DBS at nucleus accumbens followed by VC/VS and the least patients had DBS at the bilateral superolateral branch of the median forebrain bundle and the bilateral basolateral amygdala. The average YBOCS improvement did not seem to directly correlate with the percentile of patients responding to the intervention.

Well-controlled, randomized studies with larger sample sizes with close follow up are needed to provide a more accurate determination for placement of DBS for OCD.

Abstract

Purpose

This study aims to review the relationship between neurological processes and financial behavior from an interdisciplinary perspective. Individual decision-making is influenced by cognitive and affective biases; hence, it becomes pertinent to understand the origin of these biases. Neurofinance is an emerging field of finance budding from neuroeconomics and explains the relationship between human brain activity and financial behavior, drawn from interdisciplinary fields, including neurology, psychology and finance.

Design/methodology/approach

This conceptual paper extensively reviews the extant literature and performs meta-analysis to attain its research objectives.

Findings

The paper highlights the use of neuroimaging techniques in mapping the brain areas to help understand the processes in the higher cognitive areas of brain. The paper raises some new questions regarding individual preferences and choices while making financial or non-financial decisions.

Originality/value

The special focus on dysfunctions arising in brain because of injury and their impact on decision-making is also a key point in this paper and is summarized using meta-analytic forest plot. The existing literature provides instances where emotional processing is altered by injury in brain and may lead to more advantageous decisions, especially in risky situations.

Abstract

How does the human brain absorb information and turn it into skills of its own in psychotherapy? In an attempt to answer this question, the authors will review the intricacies of processing channels in psychotherapy and propose the term transprocessing (as in transduction and processing combined) for the underlying mechanisms. Through transprocessing the brain processes multimodal memories and creates reparative solutions in the course of psychotherapy. Transprocessing is proposed as a stage-sequenced mechanism of deconstruction of engrained patterns of response. Through psychotherapy, emotional-cognitive reintegration and its consolidation is accomplished. This process is mediated by cellular and neural plasticity changes.

Abstract

Although first rank symptoms focus on positive symptoms of psychosis they are shared by a number of psychiatric conditions. The difficulty in differentiating bipolar disorder from schizophrenia with affective features has led to a third category of patients often loosely labeled as schizoaffective. Research in schizophrenia has attempted to render the presence or absence of negative symptoms and their relation to etiology and prognosis more explicit. A dichotomous population is a recurring theme in experimental paradigms. Thus, schizophrenia is defined as process or reactive, deficit or non-deficit and by the presence or absence of affective symptoms. Laboratory tests confirm the clinical impression showing conflicting responses to dexamethasone suppression and clearly defined differences in autonomic responsiveness, but their patho-physiological significance eludes mainstream theory. Added to this is the difficulty in agreeing to what exactly constitutes useful clinical features differentiating, for example, negative symptoms of a true deficit syndrome from features of depression. Two recent papers proposed that the general and specific cognitive features of schizophrenia and major depression result from a monoamine-cholinergic imbalance, the former due to a relative muscarinic receptor hypofunction and the latter, in contrast, to a muscarinic hypersensitivity exacerbated by monoamine depletion. Further development of these ideas will provide pharmacological principles for what is currently an incomplete and largely, descriptive nosology of psychosis. It will propose a dimensional view of affective and negative symptoms based on relative muscarinic integrity and is supported by several exciting intracellular signaling and gene expression studies. Bipolar disorder manifests both muscarinic and dopaminergic hypersensitivity. The greater the imbalance between these two receptor signaling systems, the more the clinical picture will resemble schizophrenia with bizarre, incongruent delusions and increasingly disorganized thought. The capacity for affective expression, by definition a non-deficit syndrome, will remain contingent on the degree of preservation of muscarinic signaling, which itself may be unstable and vary between trait and state examinations. At the extreme end of muscarinic impairment, a deficit schizophrenia subpopulation is proposed with a primary and fixed muscarinic receptor hypofunction.

The genomic profile of bipolar disorder and schizophrenia overlap and both have a common dopaminergic intracellular signaling which is hypersensitive to various stressors. It is proposed that the concomitant muscarinic receptor upregulation differentiates the syndromes, being marked in bipolar disorder and rather less so in schizophrenia. From a behavioral point of view non-deficit syndromes and bipolar disorder appear most proximate and could be reclassified as a spectrum of affective psychosis or schizoaffective disorders. Because of a profound malfunction of the muscarinic receptor, the deficit subgroup cannot express a comparable stress response. None -theless, a convergent principle of psychotic features across psychiatric disorders is a relative monoaminergic-muscarinic imbalance in signal transduction.

Abstract

Purpose

The purpose of this paper is to propose an integrative framework bringing together results from neuroplasticity and decision-making from a neuroscience perspective with those from market plasticity, i.e. with which practices market actors shape markets.

Design/methodology/approach

Provided that developments in neuroscience indicate that training the brain for orientation toward efficient decision-making processes under uncertainty is possible, an in-depth analysis can be conducted by using the integrative framework, which was set up by the authors for advancing research efforts in neuroeconomics and neurofinance on these lines.

Findings

Markets have a plastic character; they can change shape and form and remain in that way thereafter. The marketers have always been causing this change to succeed in their marketing strategies and efforts. Plasticity, hitherto considered by marketing, market sociology and evolutionary economics, has a potential in financial decision-making processes, especially regarding its role in training the brain for stable financial decisions.

Research limitations/implications

The theoretical approach can be incorporated for delivering an alternative representation of the knowledge processes associated with financial decisions.

Practical implications

The practical approach can be used for improving the practical aspects of financial decision-making processes.

Originality/value

The contribution is the first of its kind which integrates neuroscience approaches of plasticity and decision-making with the concept of market plasticity from the literature on economics and management, showing their similarities and opening a new front of discussion on how these two approaches can learn from each other to increase the explanatory power of financial decision-making processes and to gain new insights for financial decision makers on how to make more efficient financial decisions in the times of uncertainty.

Abstract

Purpose

The purpose of this study is to fill the gap by investigating the relationship between age and other demographics on decision-making and leadership styles of executives in the non-profit sector.

Design/methodology/approach

This study is a quantitative research using correlation analysis and analysis of variance. The quantitative approach establishes facts, makes predictions and tests stated hypothesis and used the Pearson correlation coefficient, the ANOVA and the two-way analysis of variance. This study used surveys to collect data.

Findings

H1 states that there will be no significant difference in the decision-making models used among non-profit organizational leaders (rational, intuitive, dependent, spontaneous and avoidant) based on demographic variables: gender and age. H2 states that there will be no significant difference in the leadership style used among non-profit organizational executives (selling, telling, delegating and participating) and different dimensions of demographic variables: gender and age.

Research limitations/implications

This study explored the relationship between the demographics, age and gender and the decision-making models (rational, intuitive, dependent, spontaneous and avoidant) and leadership styles (selling, telling, delegating and participating) of executives in non-profit organizations. The age of the executives also showed to be important factors that influenced executive’s leadership styles and decision-making models as well.

Practical implications

Rational decision-making as reflected to in this study has been used by older, possibly more experienced non-profit executives. This model is favorable towards making decisions on complicated issues. The final choice rational decision-makers select will maximize the outcome; it is assumed that the decision-maker will choose the alternative that rates the highest and get the maximum benefits (Robbins and Decenzo, 2003, pp. 141-142). The researcher suggests that non-profit executives, especially the younger executives, should attend management and leadership conferences that focus on rational decision-making models as concerns business strategies and making the best choices based on possible alternatives.

Abstract

Purpose

The purpose of this paper is to present a review as well as a synthesis of the extant literature in the field of Neurofinance. The paper has been divided into eight parts. The first and second parts introduce the paper and dwell upon the brain functions in financial decisions. Part three presents the origin of Neurofinance and part four explains the difference between traditional finance, behavioural finance and neurofinance. Part five and six of the paper look into the research studies in Neurofinance and their application. Part seven gives a brief discussion on the limitations of neurofinance studies and part eight gives the conclusion.

Design/methodology/approach

The existing body of academic literature pertinent to the domain of Neurofinance was reviewed so as to provide an integrated portrayal and synthesis of the current level of knowledge in this field. This paper covers the insights on the subject for developing a deeper understanding of the investor's psychology.

Findings

Neurofinance is a very young discipline. It tries to relate the brain processes to the investment behaviour. Most of the researches in the domain of neurofinance focus on trading behaviour. It would be interesting to explore the workings of the brain for other investment behaviours too like personal financial planning decisions, etc.

Originality/value

Neurofinance is emerging as an alternate field of study and practice and this paper is an attempt to look at the development of Neurofinance and its role in developing a better understanding of the investor behaviour.
