RESUMEN

Songbirds' vocal mastery is impressive, but to what extent is it a result of practice? Can they, based on experienced mismatch with a known target, plan the necessary changes to recover the target in a practice-free manner without intermittently singing? In adult zebra finches, we drive the pitch of a song syllable away from its stable (baseline) variant acquired from a tutor, then we withdraw reinforcement and subsequently deprive them of singing experience by muting or deafening. In this deprived state, birds do not recover their baseline song. However, they revert their songs toward the target by about 1 standard deviation of their recent practice, provided the sensory feedback during the latter signaled a pitch mismatch with the target. Thus, targeted vocal plasticity does not require immediate sensory experience, showing that zebra finches are capable of goal-directed vocal planning.

RESUMEN

The process of implementation of the UN Sustainable Development Goals (SDGs) which were approved by the UN General Assembly in 2015 has not been simple, being influenced by variety of social, economic, and logistical problems. It has also been negatively affected by the COVID-19 pandemic. There are to date no specific studies aimed at assessing the extent to which higher universities institutions in Europe are active in the SDGs implementation process. Departing from this research need, this paper reports on a study aimed at examining the current degree of engagement of European universities in the implementing the SDGs. By using a multi-methods approach, which entails a review of existing documents, a survey involving participants from 22 countries and case studies, the paper maps, documents and disseminates examples of what European universities are doing to implement the SDGs, the challenges they face, and the solutions being deployed to overcome them.

RESUMEN

Goal-directed navigation requires continuously integrating uncertain self-motion and landmark cues into an internal sense of location and direction, concurrently planning future paths, and sequentially executing motor actions. Here, we provide a unified account of these processes with a computational model of probabilistic path planning in the framework of optimal feedback control under uncertainty. This model gives rise to diverse human navigational strategies previously believed to be distinct behaviors and predicts quantitatively both the errors and the variability of navigation across numerous experiments. This furthermore explains how sequential egocentric landmark observations form an uncertain allocentric cognitive map, how this internal map is used both in route planning and during execution of movements, and reconciles seemingly contradictory results about cue-integration behavior in navigation. Taken together, the present work provides a parsimonious explanation of how patterns of human goal-directed navigation behavior arise from the continuous and dynamic interactions of spatial uncertainties in perception, cognition, and action.

RESUMEN

Research in cognitive science has highlighted the effectiveness of several learning techniques, and a number of studies have analyzed their prevalence among university students and their relationship with academic achievement. In this study, we surveyed a large, heterogeneous sample of secondary school students to reveal how often they use research-supported techniques in comparison with other frequent techniques, and we analyzed the association between their study strategies and school achievement. We also assessed the associations between study techniques and several students' beliefs and attitudes toward learning (self-efficacy, goal orientation, control beliefs, growth mindset, and examination anxiety). Results showed that, except for distributed practice, only those techniques that are supported by previous research yielded an association with achievement, and they exhibited higher associations with self-efficacy, growth mindset, control beliefs, and learning goal orientation than non-supported techniques.

RESUMEN

BACKGROUND: Listening to patient voices is critical, in terms of how people experience their condition as well as their treatment preferences. This research explored the patient journey, therapy attributes and goals among treatment experienced adults with chronic lymphocytic leukemia (CLL). We sought to understand patient experiences, needs and expectations to identify areas for improvement of treatment and care delivery. METHODS: Two online surveys were developed for completion by CLL patients. In Stage 1, participants completed a best-worst scaling (BWS) task to evaluate eleven previously validated healthcare journey moments that matter (MTM). Responses were used to generate the patient experience index (PEI) score. In Stage 2, participants completed a survey that included both a discrete choice experiment (DCE) to assess drivers of treatment preferences by evaluating the relative attribute importance (RAI) of seven features and a BWS exercise which explored long-term treatment goals. RESULTS: Twenty-five patients completed Stage 1 and thirty patients Stage 2. Treatment experience was balanced between oral and intravenous medication. The most important/least satisfied MTM were treatment effectiveness, access to support and other treatments as well as monitoring progress. The median PEI score was 66.2 (out of 100). DCE results demonstrated that patients most value treatments for CLL that are associated with prolonged progression free survival (PFS; RAI: 24.6%), followed by treatments that have a lower risk of severe side effects and lower out-of-pocket costs (RAI: 19.5%, 17.4%, respectively). The remainder of the weight in decision making (38.5%) was split between the remaining attributes, namely 'mild to moderate side effects' (13.4%), 'long-term risks' (12.2%), type of treatment (i.e., oral, IV or a combination of oral and IV; 8.7%) and treatment duration (i.e., ongoing versus fixed; 4.2%). Patients preferred oral to intravenous therapy. The most valued long-term treatment goal was to be physically healthy, followed by living a long life, spending time with family/friends, and avoiding hospitalization. CONCLUSION: Treatment experienced patients with CLL are focused on receiving effective, safe therapies and value long PFS. Consideration and discussion of other attributes, such as once daily dosing, oral only medication, out-of-pocket costs and access to support services may affect patient treatment choices and ultimately enhance their healthcare experience and outcomes.

RESUMEN

BACKGROUND: Palliative rehabilitation amalgamates the principles of palliative care and rehabilitation to enhance patients' quality of life by optimizing physical function and maximizing autonomy despite advancing illness. Alongside providing non-pharmacological symptom management, it emphasizes personalized goal-setting tailored to individual needs. This case illustrates the transformative impact targeted physiotherapy interventions can have on patients' physical function, morale and motivation in spite of their expected deterioration. CASE PRESENTATION: An 85-year-old male with angioimmunoblastic T cell lymphoma was admitted to home hospice care. He was referred for physiotherapy to optimize his function and mobility despite his short prognosis. A conversation guide was used throughout the duration of therapy to identify personal goals, prescribe and review the use of appropriate interventions, and discuss future therapeutic plans. Within a month he achieved his functional goals, experienced reduced physical dependency, and had increased satisfaction in his ability to participate more actively in self-care. This also resulted in significant improvements in his confidence, mood, and overall well-being. Engaging the patient actively in his care and management journey provided him with significant motivation and hope. CONCLUSION: The case study highlights the vital role of physiotherapists in facilitating transparent communication among patients, healthcare providers, and caregivers throughout palliative rehabilitation. Through open dialogue and utilizing conversation guides, physiotherapists help understand patient preferences, goals, and motivation. This patient-centred approach ensures that therapeutic interventions align with individual needs, enhancing overall patient care and the provision of holistic palliative care.

RESUMEN

To develop and assess the preliminary effectiveness of Ontological Coaching Intervention for nursing undergraduates. Design: A pilot randomized controlled trial with a two-group pre-test and post-test followed by process-evaluation qualitative interviews. An Ontological Coaching Intervention was developed through an integration of prior literature and the collective the research team's experience, consisting of 4-6 sessions over 6-months, each lasting 30-60 minutes. Sessions encompassed exploring ontological coaching concepts, empowering nursing undergraduates to choose topics, and tailoring sessions to individual needs. Sixty undergraduates were recruited; ten were excluded for not completing the baseline questionnaires. Twenty-one nursing undergraduates were randomly assigned to the intervention group and twenty-nine undergraduates to the control group (standard academic support only). Primary (psychological well-being) and secondary (social support quantity and satisfaction, goal-setting, resilience) outcomes were measured at baseline, 3-months, and 6-months. Semi-structured interviews captured post-intervention experiences. Between-group analyses revealed a significant difference in goal-setting scores at 3-months (U = 325.5, p = 0.013), favoring the intervention group (median = 70.50, IQR = 64.25, 76.75). At 6-months, a significant difference in social support satisfaction scores (U = 114.5, p = 0.028) was found between the intervention (median = 33.00, IQR = 29.50, 35.25) and control (median = 30.00, IQR = 30.00, 35.00) groups. However, no significant between-group differences were noted in other outcome measures. Significant within-group differences were found in goal-setting scores at 3- and 6-months in the intervention group and social support quantity scores at 3- and 6-months in the control group. However, no significant within-group differences were noted in other outcome measures. Three themes were identified: Enhanced Holistic Development, Keys to Successful Coaching, and Future Directions for Successful Coaching. There is urgent need to advance research on Ontological Coaching Intervention, particularly, enhancing study rigor, broadening examinations to diverse healthcare student populations and cultural contexts, and addressing identified limitations.

RESUMEN

In September 2015, South Africa (SA) and 192 countries adopted Agenda 2030, which included the Sustainable Development Goals. With a mere 6 years to go before 2030, it is useful to understand what progress SA is making towards their attainment. In this short report, we assess progress towards meeting the maternal mortality target, globally and in SA. The maternal mortality ratio that countries are expected to reach is no more than 70 deaths per 100 000 live births. A range of sources is used to show progress, with an emphasis on the reports of the National Committee on Confidential Enquiries into Maternal deaths, which reports on the number of maternal deaths in health facilities, together with reasons for these deaths and recommendations to reduce preventable mortality.

RESUMEN

Alpha oscillations are known to play a central role in several higher-order cognitive functions, especially selective attention, working memory, semantic memory, and creative thinking. Nonetheless, we still know very little about the role of alpha in the generation of more remote semantic associations, which is key to creative and semantic cognition. Furthermore, it remains unclear how these oscillations are shaped by the intention to "be creative," which is the case in most creativity tasks. We aimed to address these gaps in two experiments. In Experiment 1, we compared alpha oscillatory activity (using a method which distinguishes genuine oscillatory activity from transient events) during the generation of free associations which were more vs. less distant from a given concept. In Experiment 2, we replicated these findings and also compared alpha oscillatory activity when people were generating free associations versus associations with the instruction to be creative (i.e. goal-directed). We found that alpha was consistently higher during the generation of more distant semantic associations, in both experiments. This effect was widespread, involving areas in both left and right hemispheres. Importantly, the instruction to be creative seems to increase alpha phase synchronisation from left to right temporal brain areas, suggesting that intention to be creative changed the flux of information in the brain, likely reflecting an increase in top-down control of semantic search processes. We conclude that goal-directed generation of remote associations relies on top-down mechanisms compared to when associations are freely generated.

RESUMEN

Excessive alcohol consumption remains a global public health crisis, with millions suffering from alcohol use disorder (AUD, or simply "alcoholism"), leading to significantly reduced life expectancy. This review examines the interplay between habitual and goal-directed behaviors and the associated neurobiological changes induced by chronic alcohol exposure. Contrary to a strict habit-goal dichotomy, our meta-analysis of the published animal experiments combined with a review of human studies reveals a nuanced transition between these behavioral control systems, emphasizing the need for refined terminology to capture the probabilistic nature of decision biases in individuals with a history of chronic alcohol exposure. Furthermore, we distinguish habitual responding from compulsivity, viewing them as separate entities with diverse roles throughout the stages of the addiction cycle. By addressing species-specific differences and translational challenges in habit research, we provide insights to enhance future investigations and inform strategies for combatting AUD.

RESUMEN

BACKGROUND: Hope has been extensively studied as a predictor of college students' academic success. Most previous studies used domain-general, global hope measures to gauge the association between hope and academic performance among college students. However, a few studies have suggested that hope is domain-specific and domain-specific academic hope measures should be included in related research to better assess the influence of hope on academic outcomes. In this study, we aimed to further examine this issue to ascertain if there is value in including academic hope measures when studying the link between hope and academic outcomes in college students. METHODS: Two samples of Hong Kong college students (total N = 1321) were recruited. Each participant completed a set of self-reported online questionnaires. RESULTS: In both samples, global hope and academic hope emerged as related but separate factors in confirmatory factor analyses. Academic hope had consistently stronger unique explanatory power on academic performance and goal setting than global hope did. On the other hand, global hope explained more variance in general wellbeing than academic hope did, but its explanatory role in academic performance was not significant. CONCLUSIONS: The findings support domain-specificity and show that hope measures explain more variance in outcomes in the matched domains. Therefore, academic hope measures should more routinely be included in related research to better evaluate the role of hope in academic pursuit among college students. Possible implications for hope interventions are also discussed.

RESUMEN

The execution of goal-oriented behaviours requires a spatially coherent alignment between sensory and motor maps. The current model for sensorimotor transformation in the superior colliculus relies on the topographic mapping of static spatial receptive fields onto movement endpoints1-6. Here, to experimentally assess the validity of this canonical static model of alignment, we dissected the visuo-motor network in the superior colliculus and performed in vivo intracellular and extracellular recordings across layers, in restrained and unrestrained conditions, to assess both the motor and the visual tuning of individual motor and premotor neurons. We found that collicular motor units have poorly defined visual static spatial receptive fields and respond instead to kinetic visual features, revealing the existence of a direct alignment in vectorial space between sensory and movement vectors, rather than between spatial receptive fields and movement endpoints as canonically hypothesized. We show that a neural network built according to these kinetic alignment principles is ideally placed to sustain ethological behaviours such as the rapid interception of moving and static targets. These findings reveal a novel dimension of the sensorimotor alignment process. By extending the alignment from the static to the kinetic domain this work provides a novel conceptual framework for understanding the nature of sensorimotor convergence and its relevance in guiding goal-directed behaviours.

RESUMEN

Goal-directed navigation requires the hippocampus to process spatial information in a value-dependent manner, but its underlying mechanism needs to be better understood. Here, we investigated whether the dorsal (dHP) and intermediate (iHP) regions of the hippocampus differentially function in processing place and its associated value information. Rats were trained in a place-preference task involving reward zones with different values in a visually rich virtual reality environment where two-dimensional navigation was possible. Rats learned to use distal visual scenes effectively to navigate to the reward zone associated with a higher reward. Inactivation of both dHP and iHP with muscimol altered the efficiency and precision of wayfinding behavior, but iHP inactivation induced more severe damage, including impaired place preference. Our findings suggest that the iHP is more critical for value-dependent navigation toward higher-value goal locations.

RESUMEN

The most dominant model of hope is cognitive, in which hope is defined as goal-directed thinking, comprising self-agency and goal route identification. Nonetheless, competing theories about the fundamental nature of hope remain and further exploration of the construct is warranted. Little is known about whether the cognitive model aligns with how higher education students themselves think about hope. Understanding how "lay" populations conceptualise and experience psychological phenomena is as important as applying scientific theory. Personal beliefs impact on how people make sense of their life experiences and on their wellbeing. Research is specifically needed to explore the conceptualisation and experience of hope within diverse student populations. A systematic review was conducted to identify published scientific research and grey literature presenting qualitative accounts of hope from higher education students. A qualitative meta-synthesis of the eight eligible reports was conducted using thematic analysis and synthesis approaches to identify conceptualisations of hope and its associations with mental health and well-being. Nine themes were identified, reflecting that hope is: fundamental; self-construal over time; goal-directed; cognitive-emotional-behavioural; connection; resilience; dynamic and reciprocal; the inverse of depression; positive. These findings were identified as reflecting conclusions in which at least a moderate level of confidence may be placed. These findings clearly align with the cognitive model of hope, but emphasise the additional facets of fundamentality, self-construal, and negative origins. The implications for higher education institutions include to promote growth mindsets, to support students to learn skills for identifying and pursuing goals, and to provide hope-enhancing interventions as part of their student support provision.

RESUMEN

The successful unfolding of many social interactions relies on our capacity to predict other people's action goals, whether these are proximal (i.e., immediate) or distal (i.e., upcoming). The present set of studies asks whether observers can predict the distal goal of two-step action sequences when presented with communicative modulations of the first movement component of the sequence. We conducted three online experiments in which we presented participants with animations of a box moving to a first target location before moving onwards to a final, either near or far, target location. The second movement component and the target locations were occluded. After observing the first movement, participants were asked to select the most likely final target location, i.e., the distal goal of the sequence. Experiment 1 showed that participants relied on the velocity modulations of the first movement to infer the distal goal. The results of Experiment 2 indicated that such predictions of distal goals are possible even when the second movement in the sequence does not contain any velocity information, thus suggesting that the information present in the first movement plays the major role in the process of linking movements to their distal goals. However, Experiment 3 showed that under some circumstances the second movement can also contribute to how observers predict a distal goal. We discuss these results in terms of the underlying simulation processes that enable observers to predict a distal goal from the observation of proximal communicative modulations.

RESUMEN

Children and adolescents with conduct problems participate in Cognitive Behavioral Therapy (CBT), either in individual or group format, in view of learning social problem-solving skills that enable them to behave in more independent and situation-appropriate ways. Parents must support their child's learning processes in everyday life and therefore these processes need attention in CBT sessions in which parents and their child participate. The social problem-solving model of CBT previously described (Matthys & Schutter, Clin Child Fam Psychol Rev 25:552-572, 2022; Matthys & Schutter, Clin Child Fam Psychol Rev 26:401-415, 2023) consists of nine psychological skills. In this narrative review we propose that instead of addressing each skill separately in sessions with both parents and their child, therapists work on three schemas (latent mental structures): (1) goals, (2) outcome expectations, and (3) normative beliefs about aggression. Based on social-cognitive and cognitive neuroscience studies we argue that these three schemas affect five core social problem-solving skills: (1) interpretation, (2) clarification of goals, (3) generations of solutions, (4) evaluation of solutions, and (5) decision-making. In view of tailoring CBT to the individual child's characteristic schemas and associated social problem-solving skills, we suggest that children and adolescents participate in individual sessions with their parents. The therapist uses Socratic questioning in order to find out characteristic schemas of the child, encourage reflection on these schemas, and explore alternative schemas that had previously been outside the child's attention. The therapist functions as a model for parents to ask their child questions about the relevant schemas with a view of achieving changes in the schemas.
