Attention‐shift vs. response‐priming explanations for the spatial cueing effect in cross‐modal tasks

The task‐irrelevant spatial location of a cue stimulus affects the processing of a subsequent target. This “Posner effect” has been explained by an exogenous attention shift to the spatial location of the cue, improving perceptual processing of the target. We studied whether the left/right location of task‐irrelevant and uninformative tones produces cueing effects on the processing of visual targets. Tones were presented randomly from left or right. In the first condition, the subsequent visual target, requiring response either with the left or right hand, was presented peripherally to left or right. In the second condition, the target was a centrally presented left/right‐pointing arrow, indicating the response hand. In the third condition, the tone and the central arrow were presented simultaneously. Data were recorded on compatible (the tone location and the response hand were the same) and incompatible trials. Reaction times were longer on incompatible than on compatible trials. The results of the second and third conditions are difficult to explain with the attention‐shift model emphasizing improved perceptual processing in the cued location, as the central target did not require any location‐based processing. Consequently, as an alternative explanation they suggest response priming in the hand corresponding to the spatial location of the tone. Simultaneous lateralized readiness potential (LRP) recordings were consistent with the behavioral data, the tone cues eliciting on incompatible trials a fast preparation for the incorrect response and on compatible trials preparation for the correct response.     

How does it feel to become a teacher? Emotions in teacher education

Academic emotions are central ingredients in student teachers’ learning. They have been shown to affect cognitive performance, motivation and achievement (e.g. Linnenbrink-Garcia et al. in Contemp Educ Psychol 36(1):13–24, 2011). However, until recently the role of emotions in student teachers’ learning has largely been neglected (e.g. Ketonen and Lonka in Proc Soc Behav Sci 69(24):1901–1910, 2012). The study focused on exploring the spectrum of academic emotions experienced by 19 student teachers in different academic activities. The results showed that student teachers experience a wide variety of emotions during their studies. A total of 18 different positive emotions and 20 different negative emotions were reported. They explicated more positive than negative emotions. Further investigations showed that student teachers reported more emotional experiences embedded in individual activities than in social activities. The results implied that the spectrum of academic emotions experienced by student teachers is wider than previous literature suggests, and that student teachers experience a wide range of academic emotions in various academic activities provided by teacher education.

Selectivity in probabilistic causality: Where psychology runs into quantum physics

Given a set of several inputs into a system (e.g., independent variables characterizing stimuli) and a set of several stochastically non-independent outputs (e.g., random variables describing different aspects of responses), how can one determine, for each of the outputs, which of the inputs it is influenced by? The problem has applications ranging from modeling pairwise comparisons to reconstructing mental processing architectures to conjoint testing. A necessary and sufficient condition for a given pattern of selective influences is provided by the Joint Distribution Criterion, according to which the problem of “what influences what” is equivalent to that of the existence of a joint distribution for a certain set of random variables. For inputs and outputs with finite sets of values this criterion translates into a test of consistency of a certain system of linear equations and inequalities (Linear Feasibility Test) which can be performed by means of linear programming. While new in the behavioral context, both this test and the Joint Distribution Criterion on which it is based have been previously proposed in quantum physics, in dealing with generalizations of Bell inequalities for the quantum entanglement problem. The parallels between this problem and that of selective influences in behavioral sciences are established by observing that noncommuting measurements in quantum physics are mutually exclusive and can therefore be treated as different levels of one and the same factor.     

Stability and change model of job resources and work engagement: A seven-year three-wave follow-up study

Using the stability and change model, conservation of resources theory and the job demands-resources model, this study aimed to determine: (1) the extent to which work engagement and job resources can be explained by a component reflecting stability and a component reflecting change in these constructs, and (2) the strength and direction of the relationship between work engagement and job resources when their stable components are controlled for. The study was carried out among 1,964 Finnish dentists over a seven-year time period (2003–2010), using a three-wave dataset. Some of the dentists had changed jobs during the follow-up, and therefore the research questions were validated among groups of job stayers and job changers. The stability and change models were examined using structural equation modelling. The results showed that 69–77% of the variance of dentists’ work engagement, and 46–49% of the variance of job resources was explained by the component reflecting stability. However, although there was a positive relationship between job resources and work engagement, the primary direction of this relationship could not be determined. Either job resources or work engagement may be considered as the initiator of this relationship. Job change did not affect the results.     

Influences of item organizability and semantic retrieval cues on word recall in very old age

Abstract

This research investigated the influence of organizational structure in the materials and category cues at retrieval on episodic memory performance in very old age. A community-based sample of healthy, very old adults (N = 224) between 75 and 96 years was presented with two lists of words: a list of semantically unrelated words and a list of words from four taxonomic categories randomly intermixed. Free recall was assessed for both tasks and, for the organizable list, subjects received a cued recall test as well. Results showed an overall age-related deterioration of memory performance, although the ability to utilize item organizability and retrieval cues remained intact across age. Evidence from data on memory performance, as well as analyses of the nature of organizable free recall, suggests that problems at both encoding and retrieval may underlie the age-related performance deficit. In addition, there were age-related increases in (a) forgetting between free and cued recall, and (b) intrusion errors. Finally, regression analyses indicated that, in addition to age, level of schooling as well as markers of general cognitive status (the Mini-Mental State Examination) and fluid intelligence (Block Design) accounted for performance variation across all memory tasks.     

PSYCHOTHERAPY AS PHASE-SPECIFIC INTERACTION

I am writing this paper to help myself, and hopefully some readers, to a better understanding of why some analysands in certain phases of the analysis develop the idea that they are homosexuals or that their analyst is homosexual. My basic thought is that even if these ideas have their individual roots and differ from case to case, they are also dependent on certain phenomena that are included in the analytic encounter and specified by different gender constellations constituting the analytic couple. I will present two examples from my own practice. From these two vignettes, I will draw some conclusions which are supported by my general psychoanalytic experience. The first example concerns male analysands. I have often seen male patients develop the fantasy that they “in reality” are homosexual. This fantasy is so common that it is a rule in my experience. I see it as a product of the fact that the psychoanalytic constellation consists, as in my case, of two men. The second example concerns female analysands. In a few cases with female analysands, I have seen the fantasy emerge that I, the analyst, am homosexual—a fantasy not seen in my male cases. Another difference is that I can't see this as a rule like the fantasy of the male analysands. In both the male and the female cases, I see the homosexual fantasies as a protection against discovery of the mother-transference to me. However, the fantasies have found different expressions depending on the specific gender constellation of the analytic couple: man and man and woman and man, respectively.     

Capturing Context-Related Change in Emotional Dynamics via Fixed Moderated Time Series Analysis

Much of recent affect research relies on intensive longitudinal studies to assess daily emotional experiences. The resulting data are analyzed with dynamic models to capture regulatory processes involved in emotional functioning. Daily contexts, however, are commonly ignored. This may not only result in biased parameter estimates and wrong conclusions, but also ignores the opportunity to investigate contextual effects on emotional dynamics. With fixed moderated time series analysis, we present an approach that resolves this problem by estimating context-dependent change in dynamic parameters in single-subject time series models. The approach examines parameter changes of known shape and thus addresses the problem of observed intra-individual heterogeneity (e.g., changes in emotional dynamics due to observed changes in daily stress). In comparison to existing approaches to unobserved heterogeneity, model estimation is facilitated and different forms of change can readily be accommodated. We demonstrate the approach's viability given relatively short time series by means of a simulation study. In addition, we present an empirical application, targeting the joint dynamics of affect and stress and how these co-vary with daily events. We discuss potentials and limitations of the approach and close with an outlook on the broader implications for understanding emotional adaption and development.     

Bayesian adaptive estimation: The next dimension

We propose a new psychometric model for two-dimensional stimuli, such as color differences, based on parameterizing the threshold of a one-dimensional psychometric function as an ellipse. The Ψ Bayesian adaptive estimation method applied to this model yields trials that vary in multiple stimulus dimensions simultaneously. Simulations indicate that this new procedure can be much more efficient than the more conventional procedure of estimating the psychometric function on one-dimensional lines independently, requiring only one-fourth or less the number of trials for equivalent performance in typical situations. In a real psychophysical experiment with a yes-no task, as few as 22 trials per estimated threshold ellipse were enough to consistently demonstrate certain color appearance phenomena. We discuss the practical implications of the multidimensional adaptation. In order to make the application of the model practical, we present two significantly faster algorithms for running the Ψ method: a discretized algorithm utilizing the Fast Fourier Transform for better scaling with the sampling rates and a Monte Carlo particle filter algorithm that should be able to scale into even more dimensions.     

Testing for selectivity in the dependence of random variables on external factors

Random variables A and B, whose joint distribution depends on factors (x,y), are selectively influenced by x and y, respectively, if A and B can be represented as functions of, respectively, (x,S_A,C) and (y,S_B,C), where S_A,S_B,C are stochastically independent and do not depend on (x,y). Selective influence implies selective dependence of marginal distributions on the respective factors: thus no parameter of A may depend on y. But parameters characterizing stochastic interdependence of A and B, such as their mixed moments, are generally functions of both x and y. We derive two simple necessary conditions for selective dependence of (A,B) on (x,y), which can be used to conduct a potential infinity of selectiveness tests. One condition is that, for any factor values x,x^′ and y,y^′,
