Dynamics of facilitation and interference in cue-priming and Simon tasks

In examining the selective suppression of responses activated by task-irrelevant stimulus attributes, such as in spatial conflict tasks, two different approaches have pointed to similar conclusions. In one approach (involving cue-priming procedures), variations of the stimulus-onset asynchrony (SOA) between task-irrelevant cues and subsequent target stimuli disclosed that the cues elicit activation of the congruent response, but this activation is subsequently suppressed. In another approach, a series of studies with the Simon task led to the formulation of the activation-suppression hypothesis. Analysis of RT distributions (in particular delta plots) disclosed that the task-irrelevant stimulus location elicits activation of the spatially corresponding response, but this activation is subsequently suppressed. The strength or efficiency of selective response suppression is expressed in the slope of the delta plot. In the present study, we combined these two approaches and found that the effects of SOA manipulation and the results of the distributional analysis converged and were positively correlated, suggesting that they involve a common mechanism of response activation followed by the selective suppression of that activation.     

Emotional responses to a negative emotion induction procedure in Borderline Personality Disorder

The aim of this study was to determine if patients with Borderline Personality Disorder (BPD) present higher emotional response than healthy controls in a laboratory setting. Fifty participants (35 patients with BPD and 15 healthy controls) underwent a negative emotion induction procedure (presentation of standardized unpleasant images). Subjective emotional responses were assessed by means of self-reported questionnaires while biological reactivity during the procedure was measured through levels of salivary cortisol (sCORT) and alphaamylase (sAA). Patients with BPD exhibited significant lower cortisol levels and higher sAA levels compared to controls. Self-reported emotional reactivity did not give rise to differences between groups but participants with BPD did present higher levels of negative emotional intensity at baseline and during the entire procedure. The findings do not give support to the emotional hyperreactivity hypothesis in BPD. However, BPD patients presented heightened negative mood intensity at baseline, which should be considered a hallmark of the disorder. Further studies using more BPD-specific emotion inductions are needed to confirm the trends observed in this study.     

Descriptive Study of the Socratic Method: Evidence for Verbal Shaping

In this study we analyzed 65 fragments of session recordings in which a cognitive behavioral therapist employed the Socratic method with her patients. Specialized coding instruments were used to categorize the verbal behavior of the psychologist and the patients. First the fragments were classified as more or less successful depending on the overall degree of concordance between the patient’s verbal behavior and the therapeutic objectives. Then the fragments were submitted to sequential analysis so as to discover regularities linking the patient’s verbal behavior and the therapist’s responses to it. Important differences between the more and the less successful fragments involved the therapist's approval or disapproval of verbalizations that approximated therapeutic goals. These approvals and disapprovals were associated with increases and decreases, respectively, in the patient’s behavior. These results are consistent with the existence, in this particular case, of a process of shaping through which the therapist modifies the patient’s verbal behavior in the overall direction of his or her chosen therapeutic objectives.     

Remarks on Wittgenstein's über Gewissheit and a Norwegian discussion

In the late forties and in the fifties, what was then known as the Oslo School of Philosophy, that is, Arne Naess and his students, received some fame, or notoriety, for its empirical investigations of lay uses of various epistemological terms, such as ‘true’, ‘certain’, ‘probable’. It is less known that Arne Naess, in 1953, opened up a series of investigations into conceptual frameworks, the comparability of conceptual frameworks, and the senses, if any, in which a conceptual framework can be said to represent knowledge. In the course of these investigations Arne Naess, together with some of his students, developed views that are strikingly close to those of Ludwig Wittgenstein in Über Gewissheit. This paper examines some of those similarities and a few dissimilarities.     

Equality and Comparative Justice

In this paper I criticize the standard argument for deontological egalitarianism, understood as the thesis that there is a moral claim to have an equal share of well-being or whatever other good counts. That argument is based on the idea that equals should be treated equally. I connect the debate over egalitarianism with that over comparative justice. A common theme is a general skepticism against comparative claims. I argue (i) that there can be no claim to equality based simply on the fact of equal worth as that fact itself does not have any value for the supposed claim holder; and (ii) intuitions that suggest otherwise can be explained away without appealing to comparative claims.     

Concepts and Intuitions: Adorno After the Linguistic Turn

Adorno's conception of conceptually articulated experience can be defended and made fruitful for a critical philosophy after the so-called linguistic turn. The aim is both to answer the criticisms raised by Jürgen Habermas and others that Adorno's philosophy remains bound by the premises of a subject-centred philosophy, and to criticize social-pragmatism from the vantage-point of Adorno's philosophy of language. It is shown that Adorno is committed to a picture of experience very much in line with the recent views of John McDowell, which extends the space of reasons beyond the space of concepts. Further, it is shown that non-inferential justification can be combined with an expressivist picture of judgment. Finally, it is argued that what is called the extended space of reasons is ultimately social; that representation, the aboutness of thought, serves expressive roles in a socially articulated space of reason-giving. The advantage of Adorno's position vis-à-vis a one-sided social-pragmatism consists in his defence of what is called subjective-material proprieties of judgment. Adorno's idea that the extended space of reasons implies the acknowledgement of what he refers to as the non-identical within conceptually articulated experience is thus reconstructed and defended. Such non-identity, it is claimed, is exhibited in successful art-works which thereby ought to be counted as forms of reasoning. On this basis, Adorno's philosophy acquires critical and normative significance after the linguistic turn.     

Psychophysiological responses to cooperation: The role of outcome and gender

Instances of sustained cooperative behaviour in humans can be considered as an adaptive strategy that enhances the probability of reaching a goal. This study investigates psychophysiological responses to cooperation in healthy subjects, while considering outcome and gender as potential moderators of these responses. Salivary cortisol levels (Csal), heart rate (HR), skin conductance level (SCL), nonspecific skin conductance responses (NSRs), and mood states were measured at different points before, during and after a Lego house‐building task in undergraduate men (n = 22) and women (n = 20). Once the task was finished, the experimenter informed the participants about the outcome obtained (positive or negative). Cooperation produces an increase in HR, SCL, and NSR responses. When the outcome is positive it produces a gradual diminution in Csal levels, but when the outcome is negative there is a significant increase in Csal levels after the task followed by a progressive decrease. Men with positive outcomes showed a lower area under curve (AUC) in Csal than women with a negative outcome. Men had more NSR responses in all periods other than the rest period. Several mood states are differently affected by the combined effect of outcome and gender. Our laboratory results can be generalized to other situations in which negotiation, mediation, and cooperative strategies are relevant for taking decisions and/or solving problems.     

An investigation of the unique,synergistic and balanced relationships between basic psychological needs and intrinsic motivation

The purpose of this study was to empirically investigate the relationship between psychological need satisfaction and intrinsic motivation as proposed by self‐determination theory. Three competing hypotheses regarding the relations between need satisfaction and intrinsic motivation were tested: additive, synergistic, and balance. Two cross‐sectional studies involving 1,254 employees from a broad range of Norwegian service organizations partly supported the first two hypotheses. Although the relationship between satisfaction of the needs for autonomy and relatedness with intrinsic motivation were significant, the one with satisfaction of the need for competence was not. Instead, competence was only related to intrinsic motivation when autonomy was high. Implications for practice and future research are discussed.
