Hand Position and Response Assignment Modulate the Activation of the Valence‐Space Conceptual Metaphor

Conceptual metaphor is ubiquitous in language and thought, as we usually reason and talk about abstract concepts in terms of more concrete ones via metaphorical mappings that are hypothesized to arise from our embodied experience. One pervasive example is the conceptual projection of valence onto space, which flexibly recruits the vertical and lateral spatial frames to gain structure (e.g., good is up ‐bad is down and good is right ‐bad is left ). In the current study, we used a valence judgment task to explore the role that exogenous bodily cues (namely response hand positions) play in the allocation of spatial attention and the modulation of conceptual congruency effects. Experiment 1 showed that congruency effects along the vertical axis are weakened when task conditions (i.e., the use of vertical visual cues, on the one hand, and the horizontal alignment of responses, on the other) draw attention to both the vertical and lateral axes making them simultaneously salient. Experiment 2 evidenced that the vertical alignment of participants’ hands while responding to the task—regardless of the location of their dominant hand—facilitates the judgment of positive and negative‐valence words, as long as participants respond in a metaphor–congruent manner (i.e., up responses are good and down responses are bad). Overall, these results support the claim that source domain representations are dynamically activated in response to the context and that bodily states are an integral part of that context.     

Extension Properties and Subdirect Representation in Abstract Algebraic Logic

This paper continues the investigation, started in Lávi?ka and Noguera (Stud Log 105(3): 521–551, 2017), of infinitary propositional logics from the perspective of their algebraic completeness and filter extension properties in abstract algebraic logic. If follows from the Lindenbaum Lemma used in standard proofs of algebraic completeness that, in every finitary logic, (completely) intersection-prime theories form a basis of the closure system of all theories. In this article we consider the open problem of whether these properties can be transferred to lattices of filters over arbitrary algebras of the logic. We show that in general the answer is negative, obtaining a richer hierarchy of pairwise different classes of infinitary logics that we separate with natural examples. As by-products we obtain a characterization of subdirect representation for arbitrary logics, develop a fruitful new notion of natural expansion, and contribute to the understanding of semilinear logics.     

Do children realize that pretend emotions might be unreal?

This research is aimed at comparing children's understanding of the distinction between external and internal emotion in deception and pretend play situations. A total of 337 children from 4 to 12 years of age participated in the study. Previous research suggests that in deception situations this understanding is very rudimentary at the age of 4 years, whereas 6-year-olds can articulate it in words. In the present work the children were asked to make this distinction in pretend play or deception tasks. The results show that in pretend play situations children start making this distinction at the age of 6 years, and their performance is better when the simulated emotion is negative rather than positive. These findings suggest that 4-year-olds are not aware that the emotions expressed in pretend play situations might be different from internal emotions.     

Psychometric properties of the Basic Family Relations Inventory (BFRI)

The aim of this study was to analyze the factor structure and internal consistency of the Basic Family Relations Inventory (BFRI) in a non-probabilistic convenience sample of 442 participants (221 couples). Exploratory factor analysis resulted in three components. In a second-order factor analysis, the three components were grouped into two factors: the Conjugal factor, which refers to how the people who exercise the parental role interact with each other (generally, the parental couple), and the Parenting factor, which represents the way in which the parental couple treat their children. Both first- and second-order factors had high reliability indices. It was concluded that the 25-item BFRI is a valid instrument to evaluate the two-dimensional model of the basic family relations theory.     

THE METAPHOR OF THE ARCHITECT IN DARWIN: CHANCE AND FREE WILL

In The Variation of Animals and Plants under Domestication, published in 1868, Darwin used the metaphor of the architect to argue in favor of natural autonomy and to clarify the role of chance in his theory of adaptive change by variation and natural selection. In this article, I trace the history of this important heuristic instrument in Darwin's writings and letters and suggest that this metaphor was important to Darwin because it helps him to explain the role of chance, and gives an argument in favor of the free will.     

The narratives of children in armed conflict: an inference to spirituality and implication to psychological intervention

From the life narratives of disadvantaged children who were victims of armed conflict, spirituality could be understood in the context of family, community, friends and aspirations. However, this initial finding needed further validation with the participants. Likewise, to utilise the findings for psychological intervention, spirituality needs to be developed with them. By doing this (living and reflecting with the children), psychologists or researchers will be able to develop programmes (spiritual or psychological) that are more meaningful and empowering to children; rather than imposing a spiritual or psychological processes that are totally alien to them. After all, at the end of the day, family, community, friends and aspirations are the most reliable resource which the disadvantaged children could constantly cling on to.     

Quantifying social asymmetric structures

Many social phenomena involve a set of dyadic relations among agents whose actions may be dependent. Although individualistic approaches have frequently been applied to analyze social processes, these are not generally concerned with dyadic relations, nor do they deal with dependency. This article describes a mathematical procedure for analyzing dyadic interactions in a social system. The proposed method consists mainly of decomposing asymmetric data into their symmetric and skew-symmetric parts. A quantification of skew symmetry for a social system can be obtained by dividing the norm of the skew-symmetric matrix by the norm of the asymmetric matrix. This calculation makes available to researchers a quantity related to the amount of dyadic reciprocity. With regard to agents, the procedure enables researchers to identify those whose behavior is asymmetric with respect to all agents. It is also possible to derive symmetric measurements among agents and to use multivariate statistical techniques.     

Influence of prime-probe stimulus onset asynchrony and prime precuing manipulations on semantic priming effects with words in a lexical-decision task

The present research examines semantic priming from attended and unattended parafoveal words. Participants made a lexical decision in response to a single central target. The target was preceded by two parafoveal prime words, with one of them (the attended prime) being precued by a peripheral cue. The main variables manipulated across experiments were cue informativeness (valid vs. neutral cues) and stimulus onset asynchrony (SOA) between prime and probe (200, 300, 600, or 1,000 ms). The results showed (a) reliable semantic priming from both attended and ignored prime words and (b) that the ignored priming effects were either negative or positive, depending on both the prime-probe SOA and cue informativeness. The present findings are discussed in relation to inhibitory versus episodic retrieval models of negative priming.     

The cognitive locus of distraction by acoustic novelty in the cross-modal oddball task

Unexpected stimuli are often able to distract us away from a task at hand. The present study seeks to explore some of the mechanisms underpinning this phenomenon. Studies of involuntary attention capture using the oddball task have repeatedly shown that infrequent auditory changes in a series of otherwise repeating sounds trigger an automatic response to the novel or deviant stimulus. This attention capture has been shown to disrupt participants' behavioral performance in a primary task, even when distractors and targets are asynchronous and presented in distinct sensory modalities. This distraction effect is generally considered as a by-product of the capture of attention by the novel or deviant stimulus, but the exact cognitive locus of this effect and the interplay between attention capture and target processing has remained relatively ignored. The present study reports three behavioral experiments using a cross-modal oddball task to examine whether the distraction triggered by auditory novelty affects the processing of the target stimuli. Our results showed that variations in the demands placed on the visual analysis (Experiment 1) or categorical processing of the target (Experiment 2) did not impact on distraction. Instead, the cancellation of distraction by the presentation of an irrelevant visual stimulus presented immediately before the visual target (Experiment 3) suggested that distraction originated in the shifts of attention occurring between attention capture and the onset of the target processing. Possible accounts of these shifts are discussed.     

Differences in dimensionality of electroencephalogram during awake and deeper sleep stages

The nonlinear dynamical systems theory provides some tools for the analysis of electroencephalogram (EEG) at different sleep stages. Its use could allow the automatic monitoring of the states of the sleep and it would also contribute an explanatory level of the differences between stages. The goal of the present paper is to address this type of analysis, focusing on the most different stages. Estimations of dimensionality were compared when six subjects were awake and in a deep sleep stage. Greater dimensionality involves more complexity because the system receives more external influences. If this dimensionality is maximum, we can consider that the time series is a noisy one. A smaller dimensionality involves lower complexity because the system receives fewer inputs. We hypothesized that we would find greater dimensionality when subjects were awake than in a deep sleep stage. Results show a noisy time series during the awake stage, whereas in the sleep stage, dimensionality is smaller, confirming our hypothesis. This result is similar to the findings reached previously by other authors.
