Goal Directed Behavior

Across development, interactions between value-based learning and memory processes promote the formation of mental models that enable flexible goal pursuit. Value cues in the environment signal information that may be useful to prioritize in memory; these prioritized memories in turn form the foundation of structured knowledge representations that guide subsequent learning. Critically, neural and cognitive component processes of learning and memory undergo marked shifts from infancy to adulthood, leading to developmental change in the construction of mental models and how they are used to guide goal-directed behavior. This review explores how changes in reciprocal interactions between value-based learning and memory influence adaptive behavior across development and highlights avenues for future research.

Memory Enhancing

Background: Glycyrrhiza glabra Linn. (Family: Fabaceae) has been known to very useful medicinal plant in the Traditional Medicinal Systems from the centuries. With ethnopharmacological values, it is well-reported plant for their traditional uses for anti-inflammatory, antioxidant, anxiolytic, expectorant activities, and antidepressant activities. Objective: Although it is described for memory enhancing activity, the present study was focused to examine the comparative effect of Glycyrrhiza glabra extracts viz. flavonoid rich (GGFE) and glycyrrhizin rich (GGGE) in stress triggered rats and to provide future research insight for this herbal drug, for which no scientific justification has been reported till now. Methods: Male Wister rats divided into 7 different groups (n= 6 per group) were given chronic foot-shock stress for 21 successive days with scheduled administration of the extracts (50 and 100 mg/kg) and standard drug (10 mg/kg) for 28 days. Elevated Plus Maze, Rectangular Maze, Morris Water Maze, and Locomotor activity were performed to test behavioral alteration and learning ability of stressed rats. Further, rats were sacrificed to assay acetylcholinesterase activity and antioxidant activity in brain samples for the mechanistic role in learning and memory. Results: Extracts of Glycyrrhiza glabra were indicated a significant alteration in stress induced learning and memory deficiency in behavioral parameters studied. These extracts were also modulated significant changes in acetylcholinesterase and antioxidant enzyme activity to improve the learning and memory of stressed rats. Conclusions: It is concluded that both extracts of Glycyrrhiza glabra (GGFE and GGGE) possess memory enhancing property in stress triggered rats. Moreover, these comparative results provided information and confirmed the high potential of GGGE in comparison to GGFE might be due to rich glycyrrhizin content present in GGGE responsible for acetylcholinesterase and antioxidant enzyme modulatory activity. Therefore, GGGE could be used as a promising lead for further mechanistic and molecular study for defining the role of glycyrrhizin of Glycyrrhiza glabra.

The Mind

Yoga is an ancient practice with Eastern roots that involves both physical postures (Asanas) and breathing techniques (Pranayamas). Yoga therapy for male sexual problems can effectively be treated through Yoga therapy, particularly with the help of Yoga poses and breathing exercises, Yoga has proven itself highly very effective in the treatment of a number of incurable and sometimes terminable diseases. Then again, Yoga's therapeutic effects are just a spin-off and supplementary. Yoga which has proved to be very effective in the treatment of many impossible and incurable diseases, the therapeutic effect of Yoga is only a by product and incidental. Problems related to sex can very well be handled with Yoga as most often these problems are more related to the mind than body. Either they are caused by lack of confidence or stress or fatigue or fear and very few times some physical cause is there. There is also a cognitive component focusing on meditation and concentration, which aids in achieving the goal of union between the self and the spiritual. Although numerous empirical studies have found a beneficial effect of Yoga on different aspects of physical and psychological functioning, claims of Yoga's beneficial effects on sexuality derive from a rich but no empirical literature. The goal of this article is to review the philosophy and forms of Yoga, to review the no empirical and (limited) empirical literatures linking Yoga with enhanced sexuality, and to propose some future research avenues focusing on Yoga as a treatment for sexual disorder.

Striatal dopamine is involved in facilitation of motor action as well as various cognitive and emotional functions. Positron emission tomography (PET) is the primary imaging method used to investigate dopamine function in humans. Previous PET studies have shown striatal dopamine release during simple finger tapping in both the putamen and the caudate. It is likely that dopamine release in the putamen is related to motor processes while dopamine release in the caudate could signal sustained cognitive component processes of the task, but the poor temporal resolution of PET has hindered firm conclusions. In this study we simultaneously collected [11C]Raclopride PET and functional Magnetic Resonance Imaging (fMRI) data while participants performed finger tapping, with fMRI being able to isolate activations related to individual tapping events. The results revealed fMRI-PET overlap in the bilateral putamen, which is consistent with a motor component process. Selective PET responses in the caudate, ventral striatum, and right posterior putamen, were also observed but did not overlap with fMRI responses to tapping events, suggesting that these reflect non-motor component processes of finger tapping. Our findings suggest an interplay between motor and non-motor-related dopamine release during simple finger tapping and illustrate the potential of hybrid PET-fMRI in revealing distinct component processes of cognitive functions.

Experienced Difficulty

People struggle to stay motivated to work toward difficult goals. Sometimes the feeling of difficulty signals that the goal is important and worth pursuing; other times, it signals that the goal is impossible and should be abandoned. In this paper, we argue that how difficulty is experienced depends on how we perceive and experience the timing of difficult events. We synthesize research from across the social and behavioral sciences and propose a new integrated model to explain how components of time perception interact with interpretations of experienced difficulty to influence motivation and goal-directed behavior. Although these constructs have been studied separately in previous research, we suggest that these factors are inseparable and that an integrated model will help us to better understand motivation and predict behavior. We conclude with new empirical questions to guide future research and by discussing the implications of this research for both theory and intervention practice.

Readiness To Learn

Purpose Multi-team systems (MTSs) are expected to respond effectively to complex challenges while remaining responsive and adaptable and preserving inter-team linking mechanisms. The leadership team of an MTS is expected to configure and reconfigure component teams to meet the unique needs of each situation and perform. How do they learn to do this? This paper, using a recent MTS learning theory as a basis, aims to begin to understand how MTSs learn and stimulate ideas for future research. Design/methodology/approach The authors use two case studies to address research questions. The first case was a snapshot in time, while the second case occurred over several months. Interviews, documents and participant observation were the data sources. Findings As suggested by theory, findings support the idea that learning triggers, the timing of the triggers and readiness to learn (RtL) affect the type of learning process that emerges. The cases showed examples of adaptive and generative team learning. Strong and clear triggers, occurring during performance episodes, led to adaptive learning. When RtL was high and triggers occurred during hiatus periods, the associated learning process was generative. Originality/value Using an available theoretical model and case studies, the research describes how MTS readiness to learn and triggers for learning affect MTS learning processes and how learning outcomes became codified in the knowledge base or structure of the MTS. This provides a framework for subsequent qualitative and quantitative research.

Abstract Background dance is a mind–body activity that stimulates neuroplasticity. We explored the effect of dance on cognitive function in older adults. Methods we searched MEDLINE, EMBASE, CENTRAL and PsycInfo databases from inception to August 2020 (PROSPERO:CRD42017057138). Inclusion criteria were (i) randomised controlled trials (ii) older adults (aged ≥ 55 years), (iii) intervention—dance and (iv) outcome—cognitive function. Cognitive domains were classified with the Diagnostic and Statistical Manual of Mental Disorders-5 Neurocognitive Framework. Meta-analyses were performed in RevMan5.3 and certainty of evidence with GradePro. Results we reviewed 3,997 records and included 11 studies (N = 1,412 participants). Seven studies included only healthy older adults and four included those with mild cognitive impairment (MCI). Dance interventions varied in frequency (1–3×/week), time (35–60 minutes), duration (3–12 months) and type. We found a mean difference (MD) = 1.58 (95% confidence interval [CI) = 0.21–2.95) on the Mini Mental State Examination for global cognitive function (moderate-certainty evidence), and the Wechsler Memory Test for learning and memory had an MD = 3.02 (95% CI = 1.38–4.65; low-certainty evidence). On the Trail Making Test-A for complex attention, MD = 3.07 (95% CI = −0.81 to 6.95; high-certainty evidence) and on the Trail Making Test-B for executive function, MD = −4.12 (95% CI = −21.28 to 13.03; moderate-certainty evidence). Subgroup analyses did not suggest consistently greater effects in older adults with MCI. Evidence is uncertain for language, and no studies evaluated social cognition or perceptual–motor function. Conclusions dance probably improves global cognitive function and executive function. However, there is little difference in complex attention, and evidence also suggests little effect on learning and memory. Future research is needed to determine the optimal dose and if dance results in greater cognitive benefits than other types of physical activity and exercise.

Tourism Destinations

The destination image and positioning studies in tourism have been limited to those dealing with the image's perceptual or cognitive component. This study examined the applicability of Russel and his colleagues' proposed affective space structure to large-scale environments (i.e., tourism destination countries) as well as its potential as a positioning structure to study affective images of tourism destinations. The multidimensional scaling analysis of 11 Mediterranean countries along with proposed affective space structure indicated that Russel and his colleagues' proposed affective space can also be applied to places that are not perceived directly. It also showed potential for studying the affective image positioning of tourism destinations. The article concludes with some theoretical and practical implications and future research areas regarding tourism destination images.

Volatile economic and labor market circumstances have significant effects on the development of people’s work careers; thus recent literature on careers has started to take into account the reality of increasingly unpredictable, nonlinear, and inherently uncertain careers. In this chapter we argue that careers in the new economy require, first, that people learn to cope with identity threats; second, that they need to change their mental models of careers; and third, that they must develop the resources to adapt to more frequent and unpredictable career transitions. Specifically we address three themes that we consider at the core of adaptation to nonlinear careers: people’s work-related identities, their conceptualization of career success, and their adaptability resources. We build a model called “identity and coping during career transitions” (ICCT), which integrates theories on identity, careers, and adaptability and could serve as an agenda for future research. Finally, we provide some guidelines for practitioners and organizations.

Abstract Shared mental models have been shown to enhance team performance. However, research has not observed the different types of sharedness of mental models that may uniquely impact the design process. Therefore, this study examines the types of sharedness of mental models that occur in design teams using Conversation Analysis on data collected from two design teams that performed activities in the early design process in a controlled lab environment. Designers were asked to develop an agreed upon list of ranked design principles, and then generate one or two solutions using the list. These design activities allow for the examination of the varying ways that designers share knowledge, negotiate, and reach understanding. Through our analysis, we identify characteristics of conversation that designers used to build shared understanding. Our results also show how team mental models are built from patterns of conversation that are evident during open-ended and unstructured design discussions. This work sets a foundation for future research to gain a deeper understanding of how designer mental models are shared in unstructured conversations that take place during design practice.

Purpose Remanufacturing is the only end-of-life (EOL) treatment process that results in as-new functional and aesthetic quality and warranty. However, applying mental model theory, the purpose of this paper is to argue that the conception of remanufacturing as an EOL process activates an operational mental model (OMM) that connects to resource reuse, environmental concern and cost savings and is thus opposed to a strategic mental model (SMM) that associates remanufacturing with quality improvements and potential price increases. Design/methodology/approach The authors support the argument by empirically assessing consumers’ multi-attribute decision process for cars with remanufactured or new engines among 202 car buyers in China. The authors conduct a conjoint analysis and use the results as input to simulate market shares for various markets on which these cars compete. Findings The results suggest that consumers on average attribute reduced utility to remanufactured engines, thus in line with the OMM. However, the authors identify a segment accounting for about 30 per cent of the market with preference for remanufactured engines. The fact that this segment has reduced environmental concern supports the SMM idea that remanufactured products can be bought for their quality. Research limitations/implications A single-country (China) single-brand (Volkswagen) study is used to support the conceptualised mental models. While this strengthens the internal validity of the results, future research could improve the external validity by using more representative sampling in a wider array of empirical contexts. Moreover, future work could test the theory more explicitly. Practical implications By selling cars with remanufactured engines to customers with a SMM that values the at least equal performance of remanufactured products, firms can enhance their profit from remanufactured products. In addition, promoting SMM enables sustainable business models for the sharing economy. Originality/value As a community, the authors need to more effectively reflect on shaping mental models that disconnect remanufacturing from analogies that convey inferior quality and performance associations. Firms can overcome reduced utility perceptions not only by providing discounts, i.e. sharing the economic benefits of remanufacturing, but even more by increasing the warranty, thus sharing remanufacturing’s performance benefit and reducing consumers’ risk, a mechanism widely acknowledged in product diffusion but neglected in remanufacturing so far.
