Mental fatigue has traditionally been defined as a condition of reduced cognitive efficiency and performance, accompanied by a subjective feeling of fatigue. Even though we could expect to find associations between the three defining characteristic of mental fatigue (performance impairment, physiological deactivation and subjective fatigue), research has shown that the emergence of inconsistencies between measures is more frequent than one might expect: people proved capable of maintaining adequate performance levels even after having declared themselves fatigued. This could be explained under the compensatory control mechanism models, which state that humans are able to provide additional resources under demanding conditions, but only at the expense of psychophysiological cost and subjective fatigue. We tested this explanation by manipulating task complexity and time performing a simulated air-traffic control task. We collected psychophysiological, performance and subjective data. A decrease in pupil size was seen in the low-aircraft-density condition, while pupil size remained constant in the high-aircraft-density condition. Participants’ task performance was optimal in both conditions, though they showed an increase in subjective feelings of fatigue, especially in the high-complexity task condition. Thus, complexity seemed to trigger compensatory mechanisms, which reallocated extra resources that physiologically activated participants in order to deal with a higher complexity task, whereas subjective fatigue could be acting as a signal to the organism of impending resource depletion. Our findings support compensatory control theories and offer an explanation of inconsistencies between fatigue measures. Further research on compensatory mechanisms is needed to enable better management of fatigue effects to prevent work-related accidents.
The proliferation of fake news in internet requires understanding which factors modulate their credibility and take actions to limit their impact. A number of recent studies have shown an effect of the foreign language when making decisions: reading in a foreign language engages a more rational, analytic mode of thinking (Costa et al., 2014, Cognition). This analytic mode of processing may lead to a decrease in the credibility of fake news. Here we conducted two experiments to examine whether fake news stories presented to university students were more credible in the native language than in a foreign language. Bayesian analyses in both experiments offered support for the hypothesis that the credibility of fake news is not modulated by language. Critically, Experiment 2 also showed a strong direct relationship between credibility and negative emotionality regardless of language. This pattern suggests that the driving force behind the engagement in an automatic thinking mode when reading fake news is not language (native vs. foreign) but emotionality.
The current study focuses on how different scales with varying demands can affect our subjective assessments. We carried out 2 experiments in which we asked participants to rate how happy or sad morphed images of faces looked. The two extremes were the original happy and original sad faces with 4 morphs in between. We manipulated language of the task—namely, half of the participants carried it out in their native language, Spanish, and the other half in their foreign language, English—and type of scale. Within type of scale, we compared verbal and brightness scales. We found that, while language did not have an effect on the assessment, type of scale did. The brightness scale led to overall higher ratings, i.e., assessing all faces as somewhat happier. This provides a limitation on the foreign language effect, as well as evidence for the influence of the cognitive demands of a scale on emotionality assessments.
The Remote Associates Test (RAT) is a measure developed by Mednick (1962) which is used to assess the convergent thinking component of creativity. This study presents a normative database in Spanish including 102 problems based on the RAT. Three sets of problems were built according to the type of between-word associations: semantic, compound, and two-word expressions. These problems were administered to a sample of 309 elementary, high-school, and university students. The results show good internal consistency as well as good convergent validity with insight problems, and discriminant validity using Guilford’s Alternative Uses Test. In addition, the results indicate age-related differences in the ability to solve the different types of problems.
The right parietal cortex has been widely associated with a spatial orienting network. Its damage frequently produces the Neglect syndrome consisting in deficits in spatial attention to the left hemifield. Neglect has also been related to temporal deficits (such as the estimation of the duration of a stimulus or the discrimination of two stimuli that occur at the same spatial location but at different time intervals). Such attentional deficits have been much less studied in the temporal as compared to the spatial domain. The current research focused on the study of temporal attention processes in patients with Neglect syndrome, specifically, on temporal preparation. We recruited 10 patients with Neglect syndrome, 10 patients without Neglect syndrome, as well as 11 healthy individuals. Each participant completed an experimental task which measures three main temporal preparation effects described in the literature: Temporal orienting and Foreperiod effects (both related to control mechanisms and prefrontal areas) and Sequential effects (automatic in nature and related to parietal and subcortical structures). The results showed a deficit in the sequential effects only in those patients who suffered from Neglect syndrome. The results suggest a causal relation between Neglect syndrome and the automatic mechanisms of temporal preparation. Since our sample of Neglect patients had suffered lesions mainly in the parietal cortex, the results are discussed taking into account the role of the parietal lobe in the processing of time and the models explaining sequential effects.
Pragmatic inferences are one way to study false memories in real-world situations. We aimed to investigate variances in responses to pragmatic implication sentences between Portuguese and American data, presenting, for the first time, normative data of cued recall and recognition for pragmatic implication sentences in Portuguese. In Study 1 we analyzed cued-recall data for Portuguese pragmatic sentences. The proportions of cued- recall for correct and inference responses of each sentence did not significantly correlate with the values of American normative data. In Studies 2a and 2b we analysed forced-recognition data for pragmatic sentences, one with American participants and English sentences (Study 2a) and the other with Portuguese participants and Portuguese sentences (Study 2b). Moreover, two conditions of sentences presentations were applied to eventually detect an influence of the sentences’ format, which was not find in both studies. The levels of recognition for correct and inferences were very similar between those two studies but the correlation, sentence by sentence, was low. Together, these results suggest an important recommendation for further studies - normed material for a specific language/culture is a crucial factor to be considered when conducting research on pragmatic inferences.
In “Constructions in analysis” (1937), S. Freud compared the analyst’s work to that of the archaeologist searching among vestiges, with the big difference that the object of our work is alive, and working with it causes fear, pain and suffering. Last year, during a visit to Pompeii and Mount Vesuvius, impressed by the strangeness of the atmosphere, by people carbonised by lava, eternal statues in a shocking atemporality among the archaic objects and traces of the place, I picked up the thread of psychoanalytic reflections on such ruins, vestiges, the layers of “ash” also present in the human psyche and their relevance in the work of the analytic cure. How to communicate the unthinkable, the unsayable, the un-representable, the barely figurable? How to transform traces of your “ancestors’ ancestors’ ancestors”, even as passed down from Superego to Superego, or via inter-transgenerational transmissions? How to transform the formless into form?
From S. Freud to D. W. Winnicott, and W. Bion, from A. Green and J. McDougall, via D. Anzieu and R. Roussillon, the author is proposing to revisit the psychic vestiges as they are expressing during the analytic process.
The majority of book-to-film adaptations operate more or less important adjustments on the initial text. In this respect, the present article attempts to investigate the psychoanalytical relevance of such a textual intervention in Roman Polanski’s 1992 film, “Bitter Moon”, based on Pascal Bruckner’s novel, “Lunes de fiel” (1981). The analysis takes the Freudian theories on sadomasochism and death instinct as a starting point.
When describing the two instincts in his work “The Ego and the Id”, Freud says that the “Eros, by bringing about a more and more far-reaching combination of the particles into which living substance is dispersed, aims at complicating life and at the same time, of course, at preserving it”. This complication, which I consider to be rather an increased complexity, can be found in the patients’ discourse through the diversification of means of expression and attributed significations, when their “stories” open up to us and to new meanings… However, when stories are meant to free the body of the burden of a stigmata, which must be covered with histories and significants, how can we identify the flux of the Eros in the counter-sense of a Thanatos that, as Freud said, “tends to return the organic to the lifeless state”? I therefore propose that we try and explore this effort to tell the story of the body expression forms trough words, in Mario Vargas Llosa’s novel, The Storyteller…
