Trial after trial: General processing consequences as a function of repetition and change in multidimensional sound

While there are pointers relating to the consequences of repetition, a general framework regarding the cognitive implications of processing multidimensional stimuli as a function of previous stimulus history is currently lacking. Three experiments using sounds varying in location and pitch were carried out, in which the immediate consequences of repeating or changing task-relevant and task-irrelevant attributes were orthogonally examined. A consistent pattern of data was shown, in that the magnitude of selective attention failure was larger when the task-relevant value repeated across trials, while differences between dimensions were larger when the task-relevant value changed across trials. These effects of irrelevance and dimension as a function of intertrial contingency are summarized in a model depicting the dynamic allocation of processing resource.     

A model for the time-order error in contrast discrimination

Trials in a temporal two-interval forced-choice discrimination experiment consist of two sequential intervals presenting stimuli that differ from one another as to magnitude along some continuum. The observer must report in which interval the stimulus had a larger magnitude. The standard difference model from signal detection theory analyses poses that order of presentation should not affect the results of the comparison, something known as the balance condition (J.-C. Falmagne, 1985, in Elements of Psychophysical Theory). But empirical data prove otherwise and consistently reveal what Fechner (1860/1966, in Elements of Psychophysics) called time-order errors, whereby the magnitude of the stimulus presented in one of the intervals is systematically underestimated relative to the other. Here we discuss sensory factors (temporary desensitization) and procedural glitches (short interstimulus or intertrial intervals and response bias) that might explain the time-order error, and we derive a formal model indicating how these factors make observed performance vary with presentation order despite a single underlying mechanism. Experimental results are also presented illustrating the conventional failure of the balance condition and testing the hypothesis that time-order errors result from contamination by the factors included in the model.     

Self-directed speech affects visual search performance

People often talk to themselves, yet very little is known about the functions of this self-directed speech. We explore effects of self-directed speech on visual processing by using a visual search task. According to the label feedback hypothesis (Lupyan, 2007a), verbal labels can change ongoing perceptual processing—for example, actually hearing “chair” compared to simply thinking about a chair can temporarily make the visual system a better “chair detector”. Participants searched for common objects, while being sometimes asked to speak the target's name aloud. Speaking facilitated search, particularly when there was a strong association between the name and the visual target. As the discrepancy between the name and the target increased, speaking began to impair performance. Together, these results speak to the power of words to modulate ongoing visual processing.     

On the relationship between visual imagery and visual perception: Evidence from priming studies

Two priming experiments using a perceptual identification task were conducted to explore the functional and representational overlap between visual imagery and visual perception. The first experiment included a study phase in which primes were either perceived or imaged objects and a perceptual identification test task in which targets were parts of studied and non-studied objects. Imagery primed identification when subjects were instructed to count the parts of the imaged objects in the study phase but not when they were instructed to focus on the global shape of the imaged objects. This result suggests that imagery involves perceptual representations identical to those involved in perception. It also suggests that the representational overlap between imagery and perception depends on the type of images generated, as some images may consist in global shapes only, whereas others may consist in detailed, multi-part shapes. In the second experiment, we used whole objects as target stimuli which provided subjects with more information to identify masked targets and thereby reduced top-down processing. Priming from imagery fell beneath significance, suggesting that this sort of priming is elicited in a large part by a transfer of top-down processes from study to test.     

Mentalizing in psychotherapy: patients’ and therapists’ reflective functioning during the psychotherapeutic process / Mentalizando en psicoterapia: funcionamiento reflexivo de pacientes y terapeutas durante el proceso psicoterapéutico

Abstract

There has been a growing interest in mentalization in clinical research given its relationship with normal and psychopathological functioning and its explanatory potential as a mechanism of psychotherapeutic change. This study uses the Reflective Functioning Scale (RFS) to identify and characterize mentalization manifestations in psychotherapeutic interaction. Method: the RFS was applied to a sample of relevant episodes — 44 sessions from five different psychotherapy processes carried out with adult patients who had different diagnoses. Results: we observed a higher probability of reflective functioning (RF) passages in relevant events than in neutral segments. There were no differences in the RF passages according to episode or actor type, but there were in RF Failures, which is more likely in patients and during rupture episodes. Discussion: although certain modifications are necessary, the RFS can be applied to clinical material, and it is a promising strategy for the study of mentalization within psychotherapy.     

The Unknown Before Discovery

Starting from the most important conquests of contemporary post-positivistic epistemology and from its authors such as Karl Popper, Thomas Kuhn, Paul Feyerabend, and Edgar Morin and going through Gadamer's hermeneutics or Wittgenstein and de Mandeville's approaches to scientific and social paradigms, this article focuses on the limits of scientific dogmas and on the overbearing rationalism that claims to explain everything, marginalizing many aspects of human life which cannot be rationalized. The scientific approach cannot be just conceptual. It must be opened to images and unusual connections. The scientist must concentrate his or her attention on limit-matters that are often unpredictable and go beyond the logical-philosophical field toward the metaphysical one. “I did not know I did not know” realized von Foerster, and aware of that, the scientist should become the specialist of the unknown, moving along the border-figures of science and philosophy.     

On the controllability of evaluative-priming effects: Some limits that are none

Two experiments examined recent claims of uncontrollability of the evaluative-priming effect. According to these claims, imposing an adaptive 600 ms response deadline prevents successful faking (Degner, 2009). Furthermore, strategic control attempts have been argued not to reduce the priming measure's sensitivity to spontaneous evaluations so that correlations of evaluative-priming effects with external criteria are not affected by attempts to fake (Bar-Anan, 2010). Here, we show that faking is possible even with an adaptive 600 ms response deadline when faking instructions do not conflict with speed pressures imposed thereby (Experiments 1 and 2). In addition, suitable faking instructions substantially affect the predictive validity of priming effects in terms of their correlations with (non-faked) self-report measures and the Implicit Association Test (Experiment 2). The previous claims about the uncontrollability of the evaluative-priming effect may thus have been premature.     

I feel good,therefore I am real: Testing the causal influence of mood on state authenticity

Although the literature has focused on individual differences in authenticity, recent findings suggest that authenticity is sensitive to context; that is, it is also a state. We extended this perspective by examining whether incidental affect influences authenticity. In three experiments, participants felt more authentic when in a relatively positive than negative mood. The causal role of affect in authenticity was consistent across a diverse set of mood inductions, including explicit (Experiments 1 and 3) and implicit (Experiment 2) methods. The link between incidental affect and state authenticity was not moderated by ability to down-regulate negative affect (Experiments 1 and 3) nor was it explained by negative mood increasing private self-consciousness or decreasing access to the self system (Experiment 3). The results indicate that mood is used as information to assess one's sense of authenticity.     

Assessing Parenting Behaviors in Euro–Canadian and East Asian Immigrant Mothers: Limitations to Observations of Responsiveness

The use of parenting measures that are developed for use with Western families without testing their validity among families from non-Western cultural backgrounds may not be appropriate. Similar parenting behaviors may affect child outcomes in different ways across different cultures. This study examined the cross-cultural validity of an observational Maternal Responsiveness coding system and of self-reports of lax/inconsistent parenting in Euro–Canadian (n = 23) and East Asian immigrant mothers (n = 23) of 4- to 7-year-old sons. In Euro–Canadian mothers, observed parenting responsiveness was associated with less lax/inconsistent parenting and fewer child behavior problems. In East Asian immigrant mothers, however, observations of greater responsiveness were not related to reports of lax/inconsistent parenting, and were associated with greater child behavior problems. Implications for the use of these parenting measures across culture groups are discussed.     

Understanding Manual-Based Behavior Therapy: Some Theoretical Foundations of Parent-Child Interaction Therapy

ABSTRACT

Manualized therapy has been criticized as being incompatible with behavior therapy. However, the majority of empirically supported, manual-based therapies utilize basic behavioral principles, such as positive reinforcement, to achieve positive change in the target behavior. Parent-Child Interaction Therapy (PCIT), for example, is a manualized treatment that makes extensive use of the empirically-derived behavioral principles of this paradigm. Understanding how and why these fundamental principles operate is essential when attempting to tailor the program ideographically to meet clients' specific needs. The purpose of this article is to provide a model of understanding and evaluating manualized treatments by beginning with a review of the theory and data-driven principles upon which PCIT is based. As a point of illustration, several of the behavioral principles embedded in PCIT, such as reinforcement, punishment, and stimulus control, are highlighted, and clinically relevant examples are presented.
