Res Computans: The Living Subject from Yeast to Human

Since modernity, the concept of subject supposes both an anthropocentric and a dualistic view of life and reality. In this study, we carry out an analytic interpretation of the Descartes’ notion of subject, in order to build a different dimension of the concept of subject. We discuss the activity of computing, as the manner by which the living subject relates with and in-forms the world. We further examine computing in the aging yeast as an example of living subject and we try to comprehend the maturity of the subjectivity in Descartes’ res cogitans and in our proposed res computans.     

Mechanisms of contextual control when contexts are informative to solve the task

An experiment was conducted using a human instrumental learning task with the goal of evaluating the mechanisms underlying the deleterious effect of context-switching on responding to an unambiguous stimulus when contexts are informative to solve the task. Participants were trained in a context-based reversal discrimination in which two discriminative stimuli (X and Y) interchange their meaning across contexts A and B. In context A, discriminative stimulus Z consistently announced that the relationship between a specific instrumental response (RI) and a specific outcome (O1) was in effect. Performance in the presence of stimulus Z was equally deteriorated when the test was conducted outside the training context, regardless of whether the test context was familiar (context B) or new (context C). This result is consistent with the idea that participants code all the information presented in an informative context as context-specific with the context playing a role akin to an occasion setter.     

Investigating the true rate of physical intimate partner violence: A review of nationally representative surveys

This review systematically investigates rates of physical intimate partner violence for both sexes in international samples. Surveys that accessed nationally representative samples, used gender inclusive methodology and neutral contexts are reviewed to determine 12-month and lifetime victimization and perpetration rates. Discrepancies between international rates, and the impact that gender equality may have upon these differences is also investigated. Electronic databases were systematically searched to identify surveys that met inclusion criteria. Eleven surveys were reviewed. Of these, Family Violence surveys had the highest methodological quality and showed equal rates for both sexes. Surveys of lesser quality typically showed higher female victimization and male perpetration rates. Countries at the extremes of gender empowerment measure scores differed in their patterns of rates. Gender equality in the US was associated with symmetry for the sexes, and inequality in Uganda associated with higher female victimization. However, as countries tended to use different methods to investigate the problem it was not possible to compare the effects of gender equality on differences in international rates of IPV. It is concluded that survey methodology needs to be consistent across nations, and specifically target family violence if true rates are to be determined and compared across the globe.     

Attributional bias instrument (ABI): validation of a measure to assess ability and effort explanations for math performance

The present work investigates the validation of a newly developed instrument, the attributional bias instrument, based on achievement attribution theories that distinguish between effort and ability explanations of behavior. The instrument further incorporates the distinction between explanations for success versus failure in academic performance. An important characteristic of the instrument is that it can be used to assess biased attributions. For instance, attributional gender bias is the tendency to generate different attributions (explanations) for female versus male students’ performance in math. Whereas boys’ successes in math are attributed to ability, girls’ successes are attributed to effort; conversely, boys’ failures in math are attributed to a lack of effort and girls’ failures to a lack of ability. Previous research has shown this bias to be committed by teachers, parents, and students themselves. In the present study, high school students in Mexico were administered the instrument and asked to generate attributions for their successes and failures in math. Findings revealed: (1) a factor analysis confirmed the proposed structure of the instrument, (2) boys and girls committed the attributional gender bias, replicating effects in U.S. samples, and (3) additional analyses involving related measures further supported valid use of the instrument.     

Our element: Flesh and democracy in Merleau-Ponty

Although Merleau-Ponty??s early phenomenology of perception and his essays on art, politics, and language already showed an affinity between the aesthetic phenomena of expression and style and the political and cultural dynamics of society at large, this paper specifically focuses on his late theorizing of the notion of flesh and its relevance to his late understanding of politics and democracy. The emergence of flesh as a concept was contemporary to Merleau-Ponty??s break with Marxism as a philosophical model and with revolutionary dialectics as a political project. It is by showing that such a break was consistently grounded on his theorizing of the being flesh of both the body and of society that this paper shows Merleau-Ponty??s unique contribution to democratic theory and to contemporary political philosophy. In the course of this analysis, it will become clear that in philosophically breaking with the position of a ??no that is a yes????i.e. the model of the revolution, which implies a total negation of the given that becomes a total affirmation of the new order (dictatorship) once in power??he would politically embrace the Weberian ??heroic liberalism????or his ??non-communist left????of parliamentary democracy.     

Recognition memory deficits in mild cognitive impairment

ABSTRACT There is no agreement on the pattern of recognition memory deficits characteristic of patients diagnosed with mild cognitive impairment (MCI). Whereas lower performance in recollection is the hallmark of MCI, there is a strong controversy about possible deficits in familiarity estimates when using recognition memory tasks. The aim of this research is to shed light on the pattern of responding in recollection and familiarity in MCI. Five groups of participants were tested. The main participant samples were those formed by two MCI groups differing in age and an Alzheimer's disease group (AD), which were compared with two control groups. Whereas one of the control groups served to assess the performance of the MCI and AD people, the other one, composed of young healthy participants, served the purpose of evaluating the adequacy of the experimental tasks used in the evaluation of the different components of recognition memory. We used an associative recognition task as a direct index of recollection and a choice task on a pair of stimuli, one of which was perceptually similar to those studied in the associative recognition phase, as an index of familiarity. Our results indicate that recollection decreases with age and neurological status, and familiarity remains stable in the elderly control sample but it is deficient in MCI. This research shows that a unique encoding situation generated deficits in recollective and familiarity mechanisms in mild cognitive impaired individuals, providing evidence for the existence of deficits in both retrieval processes in recognition memory in a MCI stage.     

Brain oscillatory activity associated with task switching and feedback processing

In this study, we sought to dissociate event-related potentials (ERPs) and the oscillatory activity associated with signals indicating feedback about performance (outcome-based behavioral adjustment) and the signals indicating the need to change or maintain a task set (rule-based behavioral adjustment). With this purpose in mind, we noninvasively recorded electroencephalographic signals, using a modified version of the Wisconsin card sorting task, in which feedback processing and task switching could be studied separately. A similar late positive component was observed for the switch and correct feedback signals on the first trials of a series, but feedback-related negativity was observed only for incorrect feedback. Moreover, whereas theta power showed a significant increase after a switch cue and after the first positive feedback of a new series, a selective frontal beta–gamma increase was observed exclusively in the first positive feedback (i.e., after the selection of the new rule). Importantly, for the switch cue, beta–alpha activity was suppressed rather than increased. This clear dissociation between the cue and feedback stimuli in task switching emphasizes the need to accurately study brain oscillatory activity to disentangle the role of different cognitive control processes.     

The adaptation of the Affective Norms for English Words (ANEW) for European Portuguese

This study presents the adaptation of the Affective Norms for English Words (ANEW; Bradley & Lang, 1999a) for European Portuguese (EP). The EP adaptation of the ANEW was based on the affective ratings made by 958 college students who were EP native speakers. Subjects assessed about 60 words by considering the affective dimensions of valence, arousal, and dominance, using the Self-Assessment Manikin (SAM) in either a paper-and-pencil or a Web survey procedure. Results of the adaptation of the ANEW for EP are presented. Furthermore, the differences between EP, American (Bradley & Lang, 1999a), and Spanish (Redondo, Fraga, Padrón, & Comesa?a, Behavior Research Methods, 39, 600–605, 2007) standardizations were explored. Results showed that the ANEW words were understood in a similar way by EP, American, and Spanish subjects, although some sex and cross-cultural differences were observed. The EP adaptation of the ANEW is shown to be a valid and useful tool that will allow researchers to control and/or manipulate the affective properties of stimuli, as well as to develop cross-linguistic studies. The normative values of EP adaptation of the ANEW can be downloaded at .     

Pure versus guided mirror exposure to reduce body dissatisfaction: a preliminary study with university women

While effectiveness of mirror exposure to reduce body dissatisfaction has been demonstrated, the exposure was almost always combined with other interventions. The aim of the study was to evaluate the effectiveness of a pure mirror exposure intervention compared with a guided mirror exposure (participants are guided to describe their body shape in a non-evaluative manner) and an imagery exposure intervention (participants are guided to describe their body through mental representation). Thirty-one women with high body dissatisfaction received five sessions of treatment under one of the three conditions. All interventions reduced body dissatisfaction, but only the mirror exposures successfully reduced the frequency of negative thoughts and feelings of ugliness. Pure mirror exposure was more effective than guided exposure for reducing body discomfort within and between sessions. Pure mirror exposure, based on the traditional extinction paradigm, led to strong emotional activation followed by a fast decrease in emotional reactivity.     

Emotional nouns affect attachment decisions in sentence completion tasks

We report three sentence completion experiments in which we manipulate the emotional dimension of the nouns in a complex noun phrase (NP) that precedes a relative clause (RC), as in the classic ambiguity in Someone shot the servant of the actress who was on the balcony. The aim was to see whether nouns such as orgy or genocide affect the well-established preference of Spanish to adjoin the relative clause high in the tree (to servant instead of actress in the example above). We manipulated the valence and arousal of the lexical entities residing in the NP. Our results indicate that (a) the inclusion of either pleasant or unpleasant words induces changes in the usual NP1 preference found in Spanish; (b) the effects of high-arousal words are especially clear, in that they pull RC adjunction towards the NP where they are located, be it the NP1 or the NP2; and (c) in the context of sentence production, these kinds of words seem intense enough to promote changes in (and even reverse) a solid syntactic bias. We discuss these findings in the light of existing theories of syntactic ambiguity resolution.
