Perception of the length of an object through dynamic touch is invariant across changes in the medium

Rotational inertia—a mechanical quantity that describes the differential resistance of an object to angular acceleration in different directions—has been shown to support perception of the properties of that object through dynamic touch (wielding). The goal of the present study was to examine if perception of the length of an object through dynamic touch depends on its rotational inertia, independent of the medium in which it is wielded. The participants (n = 14) wielded 12 different objects held in air or completely immersed in water and reported perceived lengths of those objects. Each object consisted of a rod of a particular density with a particular number of stacked steel rings attached at a particular location along its length. Perceived length was invariant across medium. In addition, a single-valued function of the major eigenvalue, I ₁, and the minor eigenvalue, I ₃, of the rotational inertia, I, of the 12 objects predicted the perceived lengths of those objects in both air and water, and the perceived lengths were invariant across the two media. These results support the hypothesis that the informational support for perception of the length of an object through dynamic touch is invariant across changes in the medium.     

Perceived Autonomy Support Moderates the Relations between Counseling Self-Efficacy and Flow among Filipino Counselors

Contemporary literature has emphasized the vital role of supervision in the professional growth of counselors and therapists. Even some counselor developmental models argued that improvement in counselor autonomy, motivation, and self-efficacy is highly contingent upon counseling supervision, especially in Western settings. Yet, there is marked scarcity of studies examining the antecedents of flow in non-Western contexts. As such, the central aim of the current study was to assess the moderating effects of perceived autonomy support from supervisors on the relations between counseling self-efficacy (CSE) and state flow among Filipino counselors. A sample of 131 Filipino counselors in Metro Manila participated in the research through answering questionnaires that measured the aforementioned constructs. The findings of correlational analyses have shown that counseling self-efficacy and perceived autonomy support are positively associated with state flow. The results of path analysis revealed a significant moderation effect. This suggests that for Filipino counselors who had greater perceptions that their supervisors provide autonomy in their counseling practice (perceived autonomy support), having lower perceived capabilities in performing counseling duties may lead to higher immersion and enjoyment in counseling activities, while for those who have low perceived autonomy support, having higher levels of counseling self-efficacy will lead to lower flow. Implications of these findings in theory and practice are elucidated.     

Spatial term apprehension with a reference object’s rotation in three-dimensional space

It has been reported that the overall shapes of spatial categorical patterns of projective spatial terms such as above and below are not influenced by the rotation of a reference object on a two-dimensional (2D) upright plane. However, is this also true in three-dimensional (3D) space? This study shows the dynamic aspects of the apprehension of projective spatial terms in 3D space by detailing how the rotation of a reference object with an inherent front influences the apprehension of projective spatial terms on a level plane by mapping their spatial categorical patterns. The experiment was designed to examine how spatial categorical patterns on a level plane changed with the rotation of a reference object with an inherent front in 3D computer graphics space. We manipulated the rotation of a reference object with an inherent front at three levels (0°, 90°, and 180° rotations) and examined how such manipulation changed the overall spatial categorical patterns of four basic Japanese projective spatial terms: mae, ushiro, hidari, and migi (similar to in front of, behind, to the left of, and to the right of in English, respectively). The results show that spatial term apprehension was affected by the rotation of the reference object in 3D space. In particular, rotation influenced the mae–ushiro and hidari–migi systems differently. The results also imply that our understanding of projective spatial terms on a level plane in 3D space is affected dynamically by visual information from 3D cues.     

A Categorical Equivalence Motivated by Kalman’s Construction

An equivalence between the category of MV-algebras and the category \({{\rm MV^{\bullet}}}\) is given in Castiglioni et al. (Studia Logica 102(1):67–92, 2014). An integral residuated lattice with bottom is an MV-algebra if and only if it satisfies the equations \({a = \neg \neg a, (a \rightarrow b) \vee (b\rightarrow a) = 1}\) and \({a \odot (a\rightarrow b) = a \wedge b}\). An object of \({{\rm MV^{\bullet}}}\) is a residuated lattice which in particular satisfies some equations which correspond to the previous equations. In this paper we extend the equivalence to the category whose objects are pairs (A, I), where A is an MV-algebra and I is an ideal of A.     

Recognition during recall failure: Semantic feature matching as a mechanism for recognition of semantic cues when recall fails

Research suggests that a feature-matching process underlies cue familiarity-detection when cued recall with graphemic cues fails. When a test cue (e.g., potchbork) overlaps in graphemic features with multiple unrecalled studied items (e.g., patchwork, pitchfork, pocketbook, pullcork), higher cue familiarity ratings are given during recall failure of all of the targets than when the cue overlaps in graphemic features with only one studied target and that target fails to be recalled (e.g., patchwork). The present study used semantic feature production norms (McRae et al., Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005) to examine whether the same holds true when the cues are semantic in nature (e.g., jaguar is used to cue cheetah). Indeed, test cues (e.g., cedar) that overlapped in semantic features (e.g., a_tree, has_bark, etc.) with four unretrieved studied items (e.g., birch, oak, pine, willow) received higher cue familiarity ratings during recall failure than test cues that overlapped in semantic features with only two (also unretrieved) studied items (e.g., birch, oak), which in turn received higher familiarity ratings during recall failure than cues that did not overlap in semantic features with any studied items. These findings suggest that the feature-matching theory of recognition during recall failure can accommodate recognition of semantic cues during recall failure, providing a potential mechanism for conceptually-based forms of cue recognition during target retrieval failure. They also provide converging evidence for the existence of the semantic features envisaged in feature-based models of semantic knowledge representation and for those more concretely specified by the production norms of McRae et al. (Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005).     

From anticipation to integration: the role of integrated action-effects in building sensorimotor contingencies

Ideomotor approaches to action control have provided evidence that the activation of an anticipatory image of previously learned action-effects plays a decisive role in action selection. This study sought for converging evidence by combining three previous experimental paradigms: the response–effect compatibility protocol introduced by Kunde (Journal of Experimental Psychology: Human Perception and Performance, 27(2), 387–394, 2001), the acquisition-test paradigm developed by Elsner and Hommel (Journal of Experimental Psychology: Human Perception and Performance, 27(1), 229, 2001), and the object-action compatibility manipulation of Tucker and Ellis (Visual Cognition, 8(6), 769–800, 2001). Three groups of participants first performed a response–effect compatibility task, in which they carried out power and precision grasps that produced either grasp-compatible or grasp-incompatible pictures, or no action effects. Performance was better in the compatible than in the incompatible group, which replicates previous observations and extends them to relationships between grasps and objects. Then, participants were to categorize object pictures by carrying out grasp responses. Apart from replicating previous findings of better performance in trials in which object size and grasp type was compatible, we found that this stimulus–response compatibility effect depended on previous response-effect learning. Taken together, these findings support the assumption that the experience of action–effect contingencies establishes durable event files that integrate representations of actions and their effects.     

Episodic-like memory in zebrafish

Episodic-like memory tests often aid in determining an animal’s ability to recall the what, where, and which (context) of an event. To date, this type of memory has been demonstrated in humans, wild chacma baboons, corvids (Scrub jays), humming birds, mice, rats, Yucatan minipigs, and cuttlefish. The potential for this type of memory in zebrafish remains unexplored even though they are quickly becoming an essential model organism for the study of a variety of human cognitive and mental disorders. Here we explore the episodic-like capabilities of zebrafish (Danio rerio) in a previously established mammalian memory paradigm. We demonstrate that when zebrafish were presented with a familiar object in a familiar context but a novel location within that context, they spend more time in the novel quadrant. Thus, zebrafish display episodic-like memory as they remember what object they saw, where they saw it (quadrant location), and on which occasion (yellow or blue walls) it was presented.     

Husserl’s appropriation of the psychological concepts of apperception and attention

In the sixth Logical Investigation, Husserl thematizes the surplus (Überschuß) of the perceptual intention whereby the intending goes beyond the partial givenness of a perceptual object to the object as a whole. This surplus is an apperceptive surplus that transcends the purely perceptual substance (Gehalt) or sensed content (empfundene Inhalt) available to a perceiver at any one time. This surplus can be described on the one hand as a synthetic link to future, possible, active experience; to intend an object is to intend it as it would appear if we were to have an exhaustively synthetic explication of it. This perceptual apperceptive surplus is, on the other hand, distinguished from the surplus that categorial form represents over the perceptual sense data. In this paper I show how the apperceptive surplus can also be understood as a synthetic link to past experience that is passively operative in any present perception. The synthetic link to both past and possible experience is a link to non-actual perceptions. Links to non-actual experience are despite their non-actuality nevertheless genuinely intentional in that they enter into the sense of any actively constituted object understood as a unity of sense. Key to this interpretation is an explanation of how Husserl appropriated the key concepts of attention and apperception from psychologists of his day, such as Stumpf and Wundt.     

The location-, word-, and arrow-based Simon effects: An ex-Gaussian analysis

Task-irrelevant spatial information, conveyed by stimulus location, location word, or arrow direction, can influence the response to task-relevant attributes, generating the location-, word-, and arrow-based Simon effects. We examined whether different mechanisms are involved in the generation of these Simon effects by fitting a mathematical ex-Gaussian function to empirical response time (RT) distributions. Specifically, we tested whether which ex-Gaussian parameters (μ, σ, and τ) show Simon effects and whether the location-, word, and arrow-based effects are on different parameters. Results show that the location-based Simon effect occurred on mean RT and μ but not on τ, and a reverse Simon effect occurred on σ. In contrast, a positive word-based Simon effect was obtained on all these measures (including σ), and a positive arrow-based Simon effect was evident on mean RT, σ, and τ but not μ. The arrow-based Simon effect was not different from the word-based Simon effect on τ or σ but was on μ and mean RT. These distinct results on mean RT and ex-Gaussian parameters provide evidence that spatial information conveyed by the various location modes are different in the time-course of activation.     

Contextual-Hierarchical Reconstructions of the Strengthened Liar Problem

In this paper we shall introduce two types of contextual-hierarchical (from now on abbreviated by ‘ch’) approaches to the strengthened liar problem. These approaches, which we call the ‘standard’ and the ‘alternative’ ch-reconstructions of the strengthened liar problem, differ in their philosophical view regarding the nature of truth and the relation between the truth predicates T r ⁿ and T r ⁿ⁺¹ of different hierarchy-levels. The basic idea of the standard ch-reconstruction is that the T r ⁿ⁺¹-schema should hold for all sentences of \(\mathcal {L}^{n}\). In contrast, the alternative ch-reconstruction, for which we shall argue in section four, is motivated by the idea that T r ⁿ and T r ⁿ⁺¹ are coherent in the sense that the same sentences of \(\mathcal {L}^{n}\) should be true according to T r ⁿ and T r ⁿ⁺¹. We show that instances of the standard ch-reconstruction can be obtained by iterating Kripke’s strong Kleene jump operator. Furthermore, we will demonstrate how instances of the alternative ch-reconstruction can be obtained by a slight modification of the iterated axiom system KF and of the iterated strong Kleene jump operator.     

Figural properties are prioritized for search under conditions of uncertainty: Setting boundary conditions on claims that figures automatically attract attention

Nelson and Palmer (2007) concluded that figures/figural properties automatically attract attention, after they found that participants were faster to detect/discriminate targets appearing where a portion of a familiar object was suggested in an otherwise ambiguous display. We investigated whether these effects are truly automatic and whether they generalize to another figural property—convexity. We found that Nelson and Palmer’s results do generalize to convexity, but only when participants are uncertain regarding when and where the target will appear. Dependence on uncertainty regarding target location/timing was also observed for familiarity. Thus, although we could replicate and extend Nelson and Palmer’s results, our experiments showed that figures do not automatically draw attention. In addition, our research went beyond Nelson and Palmer’s, in that we were able to separate figural properties from perceived figures. Because figural properties are regularities that predict where objects lie in the visual field, our results join other evidence that regularities in the environment can attract attention. More generally, our results are consistent with Bayesian theories in which priors are given more weight under conditions of uncertainty.     

EFL Teachers’ Verbal and Nonverbal Immediacy: A Study of its Impact on Students’ Emotional States,Cognitive Learning,and Burnout

Effective teacher–student interaction is an essential element of an ideal classroom which promotes the opportunity for expanded learning and stimulates the connections between students and teacher. The focus of the present study is on an instructional communication element that is teacher immediacy. It is defined as the mutual sensory and psychological stimulation between teacher and students. It can be verbal or nonverbal. Verbal immediacy is characterized as stylistic differences in expression from which like–dislike is inferred and includes using humor or personal examples, getting feedback, or even calling students by name. Nonverbal immediacy encompasses behaviors such as appropriate eye contact, the use of gestures, movement about the classroom, smiling, and vocal variety. In particular, the present study sought to explore the impact of English as a foreign language (EFL) teachers’ perceived verbal/nonverbal immediacy on students’ self-actualization, stress-control, and self-esteem. Moreover, it examined the role of EFL teachers’ immediacy behaviors in students’ cognitive learning and emotional exhaustion, which is a burnout subscale. To this end, 206 EFL students participated from selected universities of Mashhad, a city in northeast of Iran. The respondents were asked to complete five inventories about themselves and the previous EFL teacher they had had classes with. The results of structural equation modeling demonstrated that teacher immediacy behavior had a positive significant impact on all student-related variables: stress tolerance (β?=?.65, t?=?7.59), self-actualization (β?=?.69, t?=?8.02), self-esteem (β?=?.63, t?=?7.71), burnout (β?=?.31, t?=?4.05), and cognitive learning (β?=?.45, t?=?6.08). The highest impact was exerted on self-actualization and self-esteem.     

Hypothesis Testing of the <Emphasis Type="Italic">Q</Emphasis>-matrix

The recent surge of interests in cognitive assessment has led to the development of cognitive diagnosis models. Central to many such models is a specification of the Q-matrix, which relates items to latent attributes that have natural interpretations. In practice, the Q-matrix is usually constructed subjectively by the test designers. This could lead to misspecification, which could result in lack of fit of the underlying statistical model. To test possible misspecification of the Q-matrix, traditional goodness of fit tests, such as the Chi-square test and the likelihood ratio test, may not be applied straightforwardly due to the large number of possible response patterns. To address this problem, this paper proposes a new statistical method to test the goodness fit of the Q-matrix, by constructing test statistics that measure the consistency between a provisional Q-matrix and the observed data for a general family of cognitive diagnosis models. Limiting distributions of the test statistics are derived under the null hypothesis that can be used for obtaining the test p-values. Simulation studies as well as a real data example are presented to demonstrate the usefulness of the proposed method.     

Default “Gunel and Dickey” Bayes factors for contingency tables

The analysis of R×C contingency tables usually features a test for independence between row and column counts. Throughout the social sciences, the adequacy of the independence hypothesis is generally evaluated by the outcome of a classical p-value null-hypothesis significance test. Unfortunately, however, the classical p-value comes with a number of well-documented drawbacks. Here we outline an alternative, Bayes factor method to quantify the evidence for and against the hypothesis of independence in R×C contingency tables. First we describe different sampling models for contingency tables and provide the corresponding default Bayes factors as originally developed by Gunel and Dickey (Biometrika, 61(3):545–557 (1974)). We then illustrate the properties and advantages of a Bayes factor analysis of contingency tables through simulations and practical examples. Computer code is available online and has been incorporated in the “BayesFactor” R package and the JASP program (jasp-stats.org).     

Fostering Change-Oriented Behaviors: A Broaden-and-Build Model

Purpose

The purpose of this study was to develop and test a broaden-and-build model relating LMX to employees’ change-oriented behaviors (creative performance and taking charge) through the mediators of positive affect and psychological capital.

Design/Methodology/Approach

Time-lagged, two-source data were collected from 248 participants and 40 direct leaders, which composed a heterogeneous sample of professional jobs from a three-wave data collection strategy. Mplus was employed to test the proposed hypotheses.

Findings

We found that LMX predicts employees’ change-oriented behaviors through two sequential paths: (a) the positive affect mediates the relationship between LMX and employee psychological capital, and (b) psychological capital mediates the relationship between positive affect and employees’ creative performance and taking charge. Our results provide a logical explanation of the ‘broadening’ and ‘building’ mechanisms through which LMX enhances employees’ change-oriented behaviors.

Implications

This study specifically suggests affective and psychological mechanisms by promoting the broadening and building phases that facilitate the transformation of individual perceptions of LMX, positive affect, and psychological capital in explaining employees’ creative performance and taking charge.

Originality/Value

This study develops a broaden-and-build model of change-oriented behaviors and contributes to research on proactive behaviors in the context of leader-member relationships.

     

Analysing Gaze in Terms of Subjective and Objective Interpretation: Sartre and Lacan

Considering the Hegelian master–slave dichotomy over the exchange of the gaze, the paper focuses on the issue of vision and visibility, reinterpreted in Sartre’s phenomenological discussions in different ways. The Hegelian emphasis on recognition finds reflection in the treatment of vision as force expressed through visibility in Sartre and as an issue of self recognition in Lacan. Drawing the Hegelian tag with a comparative argument between Sartre and Lacan, the paper focuses on the different perspectives over the concept of gaze or look. It argues that even sharing the same Hegelian legacy regarding the notion of gaze and recognition Sartre and Lacan differs to a considerable extent in their treatment of the impact of gaze. While emphasising more on the phenomenological-existential analysis of the issue of individual recognition Sartre presents gaze as a strong alienating force released from another powerful subject affecting the intersubjective power relation, Lacan, stands on a non-reciprocal relation between seeing and seen by making a difference between the eyes of the subject that looks at and the gaze which is on the side of the object without having any capacity to become a subject. The paper concentrates on these issues over a broader argument on Sartre’s concept of intersubjective gaze.     

The Nature of <Emphasis Type="Italic">Stimmungen</Emphasis>

This essay comprises two chapters from the first part of Bollnow’s book on moods (Das Wesen der Stimmungen), namely the second chapter on the concept of Stimmung and the third chapter on Stimmungen as the sustaining foundation of the soul. It argues that moods constitute the simplest and most original form in which human life comes to know itself. Moods are understood as a specific harmony between, first, the inner and outer world; second, the states of the body and the soul; and, third, the individual faculties of the soul. Moods differ from emotions in the narrow sense, which are always intentionally directed towards a specific object, whereas moods do not have any specific object; they are states of being, structuring and coloring human existence as a whole. Hence, no system of moods is provided, but their extensive diversity is indicated. Furthermore, transient, unsteady, or “moody” moods (Launen) are distinguished from persistent or basic moods (beständige Lebensstimmungen).     

Grounding and the explanatory role of generalizations

According to Hempel’s (Aspects of scientific explanation and other essays. The Free Press, New York, 1965) influential theory of explanation, explaining why some a is G consists in showing that the truth that a is G follows from a law-like generalization to the effect that all Fs are G together with the initial condition that a is F. While Hempel’s overall account is now widely considered to be deeply flawed, the idea that some generalizations play the explanatory role that the account predicts is still often endorsed by contemporary philosophers of science. This idea, however, conflicts with widely shared views in metaphysics according to which the generalization that all Fs are G is partially explained by the fact that a is G. I discuss two solutions to this conflict that have been proposed recently, argue that they are unsatisfactory, and offer an alternative.
