Do “mudsplashes” induce tactile change blindness?

The phenomenon of change blindness (the surprising inability of people to correctly perceive changes between consecutively presented displays), primarily reported in vision, has recently been shown to occur for positional changes presented in tactile displays as well. Here, we studied people’s ability to detect changes in the number of tactile stimuli in successively presented displays composed of one to three stimuli distributed over the body surface. In Experiment 1, a tactile mask consisting of the simultaneous activation of all seven possible tactile stimulators was sometimes presented between the two to-be-discriminated tactile displays. In Experiment 2, a “mudsplash” paradigm was used, with a brief irrelevant tactile distractor presented at the moment of change of the tactile display. Change blindness was demonstrated in both experiments, thus showing that the failure to detect tactile change is not necessarily related to (1) the physical disruption between consecutive events, (2) the effect of masking covering the location of the change, or (3) the erasure or resetting of the information contained within an internal representation of the tactile display. These results are interpreted in terms of a limitation in the number of spatial locations/events that can be consciously accessed at any one time. This limitation appears to constrain change-detection performance, no matter the sensory modality in which the stimuli are presented.     

Step changes in the intertrial interval in the midsession reversal task: Predicting pigeons' performance with the learning-to-time model

Our goal was to assess the role of timing in pigeons' performance in the midsession reversal task. In discrete-trial sessions, pigeons learned to discriminate between 2 stimuli, S1 and S2. Choices of S1 were reinforced only in the first half of the session and choices of S2 were reinforced only in the second half. Typically, pigeons choose S2 before the contingency reverses (anticipatory errors) and S1 after (perseverative errors), suggesting that they time the interval from the beginning of the session to the contingency reversal. To test this hypothesis, we exposed pigeons to a midsession reversal task and, depending on the group, either increased or decreased the ITI duration. We then contrasted the pigeons' performance with the predictions of the Learning-to-Time (LeT) model: In both conditions, preference was expected to reverse at the same time as in the previous sessions. When the ITI was doubled, pigeons' preference reversal occurred at half the trial number but at the same time as in the previous sessions. When the ITI was halved, pigeons' preference reversal occurred at a later trial but at an earlier time than in the previous sessions. Hence, pigeons' performance was only partially consistent with the predictions of LeT, suggesting that besides timing, other sources of control, such as the outcome of previous trials, seem to influence choice.     

From Interpretation to Commentary: Truth and Meaning in Psychotherapy

Some of the epistemological consequences of adopting the narrative point of view in psychotherapy are explored. Attempts to apply principles and norms from the philosophy of science to psychotherapy are criticized, since psychotherapy is not a science, but a technique. In addition, those models, related to the acquisition of knowledge, that consider that knowledge could increase by apposition without transforming the subject who is knowing are discussed. Natural science and hermeneutic metaphors are not suitable for understanding the practice of psychotherapy. Traditionally, the interpretation of symptoms or problems to solve has been the main instrument in therapy. In other words, the therapist tries to look for the truth hidden under the symptom, which then becomes a sign. Our proposition is to substitute these metaphors for the paradigm of text commentary. Text commentary, instead of providing a unique truth, provides a set of meanings suggested by a commentary. Characteristics that allow one to distinguish a good and a bad commentary, and implications of the paradigm described for the training of psychotherapists, are discussed.     

Further exploration of Filipino personality structure using the lexical approach: do the big-five or big-seven dimensions emerge?

Filipino college students (N=740) rated their personalities using 502 reasonably familiar terms from a comprehensive taxonomy of Filipino trait adjectives. Using factor analysis, we replicated the seven Filipino personality dimensions identified in a previous study (Church, Reyes, Katigbak and Grimm, 1997). At least seven factors are needed to identify dimensions resembling all of the Big Five. When positive- and negative-evaluation terms are included a Negative-Valence dimension is found, but positive-evaluation terms blend with Intellect terms rather than identifying a distinct dimension. Thus, the cross-cultural generalizability of the Big-Seven model (Tellegen and Waller, 1997) is not completely supported. Correlational analyses consistently show good one-to-one correspondence between the Filipino Gregariousness, Concern for Others versus Egotism, Conscientiousness, and Intellect dimensions and Big-Five Extraversion, Agreeableness, Conscientiousness, and Intellect, respectively. The Filipino Temperamentalness and Self-assurance dimensions, although moderately correlated with Neuroticism, are multidimensional in terms of the Big Five. © 1998 John Wiley & Sons, Ltd.     

Color-Conscious Multicultural Mindfulness Training in the Counseling Field

The Color-Conscious Multicultural Mindfulness (CCMM) training focuses on addressing intercultural relationship ruptures, individual inequity, and systemic disparities. In this randomized control study, the authors examined the CCMM training effectiveness with 39 prelicensed counselors and counseling students using repeated measures analyses of covariance. Participants reported statistically significant changes in multicultural competence; mindfulness; and color-blind racial attitudes related to privilege, institutional discrimination, and blatant racism. Implications for counselor training practices and future research are provided.     

Complex in memory,mind in matter: walking hand in hand

This paper aims to highlight four major points: first: a ‘Jungian attitude’ understood as a viewpoint which enables work with interconnectedness through various fields of knowledge. Second, that complexes are dynamic, as is memory, and that both are transformed by experience and develop hand in hand with each other i.e., the transformation of the complex occurs through the transformation of memory as embodied in internal working models, and vice versa. Third, complexes and archetypes are linked to each other in matrices of one form or another and lead to the complexity of the psyche, which is a developing system. Fourth, the analytical process provides an arena that enables and consolidates interconnections that foster a better intrapsychic transition. The analytic meeting promotes profound changes, redesigning our neural architecture as well as our psychic landscape.     

Indistinguishability, Choices, and Logics of Agency

This paper deals with structures ${\langle{\bf T}, I\rangle}$ in which T is a tree and I is a function assigning each moment a partition of the set of histories passing through it. The function I is called indistinguishability and generalizes the notion of undividedness. Belnap’s choices are particular indistinguishability functions. Structures ${\langle{\bf T}, I\rangle}$ provide a semantics for a language ${\mathcal{L}}$ with tense and modal operators. The first part of the paper investigates the set-theoretical properties of the set of indistinguishability classes, which has a tree structure. The significant relations between this tree and T are established within a general theory of trees. The aim of second part is testing the expressive power of the language ${\mathcal{L}}$ . The natural environment for this kind of investigations is Belnap’s seeing to it that (stit). It will be proved that the hybrid extension of ${\mathcal{L}}$ (with a simultaneity operator) is suitable for expressing stit concepts in a purely temporal language.     

The Church–Fitch knowability paradox in the light of structural proof theory

Anti-realist epistemic conceptions of truth imply what is called the knowability principle: All truths are possibly known. The principle can be formalized in a bimodal propositional logic, with an alethic modality ${\diamondsuit}$ and an epistemic modality ${\mathcal{K}}$ , by the axiom scheme ${A \supset \diamondsuit \mathcal{K} A}$ (KP). The use of classical logic and minimal assumptions about the two modalities lead to the paradoxical conclusion that all truths are known, ${A \supset \mathcal{K} A}$ (OP). A Gentzen-style reconstruction of the Church–Fitch paradox is presented following a labelled approach to sequent calculi. First, a cut-free system for classical (resp. intuitionistic) bimodal logic is introduced as the logical basis for the Church–Fitch paradox and the relationships between ${\mathcal {K}}$ and ${\diamondsuit}$ are taken into account. Afterwards, by exploiting the structural properties of the system, in particular cut elimination, the semantic frame conditions that correspond to KP are determined and added in the form of a block of nonlogical inference rules. Within this new system for classical and intuitionistic “knowability logic”, it is possible to give a satisfactory cut-free reconstruction of the Church–Fitch derivation and to confirm that OP is only classically derivable, but neither intuitionistically derivable nor intuitionistically admissible. Finally, it is shown that in classical knowability logic, the Church–Fitch derivation is nothing else but a fallacy and does not represent a real threat for anti-realism.     

Dysfunctional Personal Experiences and Existential Dilemmas

This article presents a theoretical discussion of the results from the research, “An Existential Understanding of Anxiety: An Integration of the Ideas of May, Yalom, and Schneider.” It focuses on the development of dysfunctional experiences according to the theoretical perspectives of Rollo May, Irvin Yalom, and Kirk Schneider. Dysfunctional experiences emerge when human beings experience (implicitly or consciously) different existential dilemmas and are unable to make consistent decisions and confront the experience of anxiety that results from such contact. In this sense, dysfunctional experiences are not developed simply from the consciousness of existential givens, as suggested by Yalom (1980 Yalom , I. ( 1980 ). Existential psychotherapy . New York , NY : Basic Books . [Google Scholar]), but by the dialectical and paradoxical relationship with the following human dilemmas: life versus death, freedom versus determinisms, isolation versus intersubjectivity, meaning versus insignificancy, individuation versus adaptation, and sense of power versus impotence. This idea implies that anxiety and dysfunctional experiences could emerge, in daily life, from the need to take concrete decisions when faced with several possibilities or dilemmas, and not only from the awareness of those possibilities.     

Processing Italian Relative Clauses: Working Memory Span and Word Order Effects on RTs

In this study, the authors aim to clarify whether the subject–object asymmetry in relative clause comprehension is due to the use of parsing strategies (Active Filler Theory) or to a greater memory load generated by object sentences. Two experiments investigate how individual differences in working memory span may influence the reading times of relative sentences in Italian, a language characterized by a flexible structure. The results of Experiment 1 indicate that object extraction is more complex than subject extraction when sentences have a canonical structure. Furthermore, low-span participants have particular difficulties with object relative sentence comprehension. The results of Experiment 2 show that subject-relative clauses with uncanonical structures are more complex to understand than object-relative clauses, and low-span participants have more difficulties than high-span participants in elaborating both subject and object relative clauses. These data seem to be coherent with the Active Filler Theory.
