Inter-individual and age differences in exploration, neophobia and problem-solving ability in a Neotropical raptor (Milvago chimango)

Animal innovations have far-reaching ecological and evolutionary consequences. The occurrence and persistence of an innovation require several processes, including exploration, social and asocial learning, and low neophobia. In addition, the identity of the innovator may determine how these new behaviours are socially transmitted. Taking into account inter-individual and age differences, we investigated three correlates of animal innovation: object exploration, neophobia level and novel problem-solving ability in an opportunistic generalist raptor, the Chimango Caracara (Milvago chimango). Eighteen individuals (7 adults and 11 juveniles) were caught during the non-breeding period and housed in individual cages in outdoor aviaries. Each bird was given three tests: exploration, neophobia and problem-solving. Individuals differed in their response to novel situations both within and between age groups. Most of the juveniles were more explorative and had a lower neophobic response to a strange object than adult birds, but both age groups were able to solve a novel problem when given a food reward. In juveniles, neophobia level and problem-solving performance were inversely related; however, we found no relationship between these behaviours in adults. Exploration did not correlate with neophobia or problem-solving ability for either age group. This research is one of the few studies exploring the inter-individual and age differences in behavioural innovation and their correlates in a bird of prey. The explorative tendency, low neophobia and ability to innovate showed by M. chimango may be advantageous for this generalist and opportunistic raptor and might be some of the factors underlying its ecological success.     

Emotion affects action: Midcingulate cortex as a pivotal node of interaction between negative emotion and motor signals

Affective pictures drive the activity of brain networks and impact behavior. We showed previously that viewing unpleasant pictures interfered in the performance of a basic nonemotional visual detection task. In the present study, we employed functional magnetic resonance imaging to test the hypothesis that behavioral interference may result from the interaction between negatively valenced and motor-related signals in the brain. As in our previous study (Pereira et al., 2006), participants performed a simple target detection task that followed the presentation of unpleasant or neutral pictures. Our results revealed that an unpleasant emotional context modulated evoked responses in several regions engaged by the simple target detection task. In particular, the midcingulate cortex was recruited when participants performed target detection trials during the unpleasant context, and signal responses in this region closely mirrored the pattern of behavioral interference (as revealed via reaction time). Our findings suggest that the midcingulate cortex may be an important site for the interaction between negatively valenced signals and motor signals in the brain and that it may be involved in the implementation of defensive responses, such as freezing.     

Change in body image and psychological well-being during behavioral obesity treatment: Associations with weight loss and maintenance

This study reports on outcomes from a behavioral obesity treatment program, evaluating if treatment-related changes in body image and psychological well-being are predictors of weight change during treatment and after follow-up. Participants were 142 overweight/obese women (BMI = 30.2 ± 3.7 kg/m²; age = 38.3 ± 5.8 years) participants in a behavioral treatment program consisting of a 4-month treatment period and a 12-month follow-up. Psychosocial variables improved during treatment and these changes were correlated with 4-month weight reduction. Short-term changes in body size dissatisfaction (p = .002) and mood (p = .003) predicted long-term weight loss. Additional results suggest that there might be a predictive role of short-term changes in body size dissatisfaction and self-esteem on long-term weight loss after accounting for initial weight change (p < .028). We conclude that, along with weight changes, cognitive and affect-related processes influenced during obesity treatment may be related long-term success, in some cases independently of initial weight loss.     

Humanismo Del Diecisiete En La Postmodernidad Del Veintiuno

It would be possible to be affirmed that the most of the educational goals that modernity assumes, they settled down from the Renaissance. The postmodern age, in its critic to the modern period, demands the recovery of some losses. At the time of fast changes as it happens in the Renaissance, the Humanism originates a fruitful debate. According to the authors protagonists, the controversy became a dialogue plenty of common questions to which we find in the contemporary discussion. The reflection on the thought of one of the most representative and well-known authors, Comenio, it serves to think on the encounter of traditions in Philosophy of Education. He is a thinker who supplies the basis for his educational practice on a Philosophy of education and projects a reform to confront some problems that in the essential are repeated today.      

On the Causal Completeness of Physics

According to an increasing number of authors, the best, if not the only, argument in favour of physicalism is the so‐called ‘overdetermination argument’. This argument, if sound, establishes that all the entities that enter into causal interactions with the physical world are physical. One key premise in the overdetermination argument is the principle of the causal closure of the physical world, said to be supported by contemporary physics. In this paper, I examine various ways in which physics may support the principle, either as a methodological guide or as depending on some other laws and principles of physics.     

Acquiescent Responding in Balanced Multidimensional Scales and Exploratory Factor Analysis

Personality tests often consist of a set of dichotomous or Likert items. These response formats are known to be susceptible to an agreeing-response bias called acquiescence. The common assumption in balanced scales is that the sum of appropriately reversed responses should be reasonably free of acquiescence. However, inter-item correlation (or covariance) matrices can still be affected by the presence of variance due to acquiescence. To analyse these correlation matrices, we propose a method that is based on an unrestricted factor analysis and can be applied to multidimensional scales. This method obtains a factor solution in which acquiescence response variance is isolated in an independent factor. It is therefore possible, without the potentially confounding effect of acquiescence, to: (a) examine the dominant factors related to content latent variables; and (b) estimate participants’ factor scores on content latent variables. This method, which is illustrated by two empirical data examples, has proved to be useful for improving the simplicity of the factor structure.

The relationship between acceptance,fatigue, and subjective cognitive impairment in hematologic cancer survivors

Background/Objective: Cancer and its treatment can have a detrimental impact on psychological well-being. Acceptance as the basis of acceptance and commitment therapy (ACT) has shown beneficial effects on depression and anxiety. However, its relationship to fatigue and cognitive impairment has not been investigated. A protective effect of acceptance may open up a new target for psychological intervention.Method: A cross-sectional postal survey was undertaken. 922 hematological cancer survivors (≥ 2.5 years post diagnosis) were recruited through two regional cancer registries in Germany. Acceptance (AAQ-II), fatigue (BFI) and subjective cognitive impairment (AFI) were assessed.Results: Higher levels of acceptance were negatively associated with fatigue and subjective cognitive impairment (R²= .34 and R²= .26, respectively). The relationship between fatigue and fatigue-related impairment of daily life was weaker for survivors with high acceptance.Conclusions: Acceptance is strongly associated with fatigue and subjective cognitive impairment. ACT may be useful to reduce symptoms of fatigue and subjective cognitive impairment in cancer survivors.     

Subjective Well-Being of Brazilian Children from Different Family Settings

Subjective well-being concerns an evaluation of one’s life, considering cognitive and affective aspects. Contextual factors, such as family, may influence this process. One of the main development contexts of children is family and aspects of these relationships, such as different settings, might contribute to children’s subjective well-being. The aim of this study was to compare the well-being of children from different family settings (intact, single-parent, stepfamilies, multigenerational). Participants were 2,135 boys and girls, from 9 to 13 years old (M = 10.97, SD = 0.99), students of public and private schools from a Brazilian southern State. Children answered a questionnaire with sociodemographic variables and three well-being scales (PWI-SC, BMSLSS, GDSI). Children were divided in four groups according to whom they live with (intact, single-parent, stepfamilies, multigenerational families). To evaluate differences between groups a Multivariate Analysis of Variance (MANOVA) were performed, considering well-being scales as dependent variables and family setting as independent variable. Results indicated significant differences in the well-being of children in relation to their family setting and age. Children from intact families showed significant positive differences on the well-being from children of other settings (the lowest means were from the children of stepfamilies). It is argued that transitions and instability that children are being subjected to may affect their well-being.

     

Employee adaptive performance and job satisfaction during organizational crisis: the role of self-leadership

This study tests the hypothesis that self-leadership is positively related with employee adaptive performance and job satisfaction in rapid change and unpredictable work environments. This assumption was tested through a quasi-experimental study regarding the implementation of a self-leadership training programme in the Private Banking department of an international bank. Change in private bankers’ self-leadership, adaptive performance and job satisfaction was measured three times, over a period of 8 months. During the fourth month of the training programme implementation, the bank underwent an unexpected bailout. Fifty-two private bankers were randomly assigned to an experimental group (n = 28) and to a control group (n = 24). The results showed an increase in self-leadership, adaptive performance and job satisfaction for the experimental group, while job satisfaction decreased for participants in the control group. Our findings suggest that change in the level of self-leadership is positively related with change in the level of adaptive performance and job satisfaction over time. This study presents new evidence that individual adaptive performance and job satisfaction can be enhanced through self-leadership training. Self-leadership training can be used as a valuable tool to help organizations improve employees’ adaptive performance and job satisfaction, especially during organizational crisis.     

Les objets connectés et applications de santé : étude exploratoire des perceptions,usages (ou non) et contextes d’usage

In a contemporary context of major health challenges, the market of digital technologies has increasingly developed in past years. This article aims to explore main profiles of use in relation to connected objects and health apps, as well as attitudes related to uses, non-uses and contexts of use. Therefore, our objective is to contribute to the scientific debate by proposing an empirical study in psychology that focusses on the perspectives of consumers and non-consumers of these technologies in the French-speaking part of Switzerland. To do this, a survey was conducted among participants of a large public health exhibition (n = 760). According to our results, the majority of respondents declare not having a connected object/health app and a third of non-users does not intend to acquire such technologies. Also, there is a trend among younger generations to have a connected object/health app. Concerning the contexts of use, such technologies are employed to self-track physical activity and eating practices. The degree of satisfaction of such use is rather high. Given these results, our analyses point out a divide within our sample, between individuals who seem resistant and declare not willing to have this kind of technology and those who use it in the long run. These results cast new light upon concrete uses and contexts of use among consumers and non-consumers of connected objects/health apps beyond techno-scientific promises that prevail today in our societies.
