Probability judgments of agency: Rational or irrational?

We studied how people attribute action outcomes to their own actions under conditions of uncertainty. Participants chose between left and right keypresses to produce an action effect (a corresponding left or right light), while a computer player made a simultaneous keypress decision. In each trial, a random generator determined which of the players controlled the action effect at varying probabilities, and participants then judged which player had produced it. Participants’ effect control ranged from 20% to 80%, varied blockwise, and they could use trial-by-trial feedback to optimize the accuracy of their agency judgments. Participants tended to attribute action effects to themselves (agency bias), probably reflecting a rational guessing strategy of always naming the more likely player. However, participants systematically neglected information favoring the computer player as the agent, even under conditions where this bias could only harm judgment accuracy. We conclude that agency biases have both rational and irrational components.     

Unconscious perception or not? An evaluation of detection and discrimination as indicators of awareness

Most investigations of unconscious perception use a dissociation design in which an awareness variable (e.g., detection) is compared with a perceptual processing variable (e.g., identification). Unconscious perception is inferred when the awareness variable lacks sensitivity to the stimulus but evidence of perceptual processing is still obtained. In two studies we examined the relationship between word identification and detection (Study 1) or discrimination (words vs. nonwords; Study 2) with a variety of techniques. In both studies, dissociations suggestive of unconscious perception occurred when the data were examined with subjective threshold approaches, but these differences disappeared when the variables were compared with techniques derived from signal detection theory (SDT). These results do not support unconscious perception in subjective threshold paradigms. In addition, detection appears to be the most sensitive and appropriate task for assessing stimulus awareness, provided that several SDT assumptions are met.     

The integration of psychotherapy: Goal or utopia?

Both researchers and therapists stress the importance of integrating different forms of psychotherapy. Integration may be achieved in three ways. Supporters of the “empirical strategy” believe that more research is the solution. Followers of the “conceptual strategy” try to theorize on psychotherapy using psychological and sociological concepts. Other researchers see a “linguistic strategy” as the way to achieving a better understanding of psychotherapy. Whether any of these strategies will enable us to increase our insight into psychotherapy is questionable. All focus on technical aspects, that is, on the means to achieve effects. Yet, therapeutic effects cannot be understood unless they are interconnected with diagnostics. This paper argues that an integrated theory should be developed which includes diagnostics and treatment and which is supported by a theory on psychological (dys)functioning.     

Are mothers of stutterers different? An investigation of social-communicative integration

Many speech-language pathologists assume that parent-child communicative interactions are critical precipitating or maintaining factors in the onset and development of stuttering. Although parents are frequently counseled to alter their attitudes or behaviors, no studies have pinpointed specific parental behaviors as increasing children's disfluency. The purpose of this study was to analyze differences between 12 mothers of stutterers and 12 mothers of nonstutterers in their social-communicative interactions with their own child, an unfamiliar stutterer, and an unfamiliar nonstutterer. Ten minutes of free-play interaction between each mother and child were video recorded from behind a one-way mirror. Results indicate that the two groups of mothers differed significantly only in their use of routine statements. Other findings indicate that stuttering children used significantly more positive and imperative statements than nonstuttering children. All children asked significantly more questions of their own mothers than of unfamiliar mothers.     

Processing alternative explanations of behavior: correction or integration?

Three experiments investigated how activation of knowledge about situational forces affects discounting in dispositional inference tasks. Each experiment varied a different knowledge activation factor--salience, accessibility, or specificity of situational information. In addition, all 3 experiments varied situational demands and cognitive load. The results showed that cognitive load eliminated discounting when situational information was low in salience, accessibility, or specificity. However, when situational information was more salient, accessible, or specific, it produced strong discounting effects even when perceivers were under cognitive load. These results are discussed in terms of correction and integration models of dispositional inferences from behavior.     

PDP and Gestalt: An integration?

Summary The possibility of a synthesis between parallel distributed processing approaches (PDP) and Gestalt psychology is discussed. The empiricist outlook of PDP is an obstacle to such a synthesis. Gestalt's belief in organization of the psychological field as the basic principle is not shared by the PDP approach. It is claimed that, nevertheless, Gestalt psychology can use PDP techniques for modeling organization processes, provided that some constraints are obeyed. From a PDP point of view, importing Gestalt constraints could be a useful strategy for obtaining testable predictions.     

Public Debate – An Act of Hostility?

This paper focuses on eristic in political debate of the forensic, or confrontational, type. First, some findings on the enactment and persuasiveness of hostility in a series of Danish TV-debates 1975–85 are presented, including a list of the clearly hostile debater's characteristics and a subdivision of conspiracy arguments. This presentation serves to illustrate that hostility is less persuasive than argumentation practitioners and theorists tend to assume. Next, the widespread notion of debate as a genre half-way between the quarrel and the critical discussion is challenged in a discussion of Douglas N. Walton's distinction between types of dialogue. It is maintained that the normative model of confrontational debate excludes the quarrel and that debate should not be perceived as second-rate critical discussion.

Performance as annihilation or integration?1

What happens when the analyst has the impression of being annihilated by the patient? Analysts have a tendency to use more general, i.e. simplifying, constructions such as destructiveness, psychosis or death instinct as explanatory models. In the authors' view, these constructions in the end evade rather than mirror clinical reality. More recent research points to promising possibilities of differentiation, e.g. psychotic mechanisms which are‐as yet undiscussed‐based on Freud's notion of the partial ‘rent in the relation between ego and external world’. These findings emphasize the restitutive function of a symptom or disturbance, i.e. destruction of a relationship which hinders the therapeutic process and which is not understood initially, instead of solely stressing the destructive meaning in a tabooing gesture. The concept of performance attempts to replace simplifying models with a discriminant process, and will be preliminarily defined and explained in delineation to terms already in use such as acting out, enactment, and role responsiveness. The authors explore the question of how the perception of unthought certainty in the performance can either be recognized as a blueprint, i.e. organizing activity, or as the destruction of the relationship so that a new one can emerge. The evidence from a detailed clinical example shows that many treatments can fail at this point and demonstrates how an understanding of performance in this sense offers a chance for integrating processes that otherwise impede treatment.     

Thought insertion: Abnormal sense of thought agency or thought endorsement?

The standard approach to the core phenomenology of thought insertion characterizes it in terms of a normal sense of thought ownership coupled with an abnormal sense of thought agency. Recently, Fernández (2010) has argued that there are crucial problems with this approach and has proposed instead that what goes wrong fundamentally in such a phenomenology is a sense of thought commitment, characterized in terms of thought endorsement. In this paper, we argue that even though Fernández raises new issues that enrich the topic, his proposal cannot rival the version of the standard approach we shall defend.     

In search of the optimal measure of awareness: Discrete or continuous?

Studies of perceptual awareness require sensitive measures reflecting subjective judgments of visibility. Two scales have been proposed for this purpose: the Continuous Scale (CS) and the Perceptual Awareness Scale (PAS). Here we compare the scales in the context of the Gabor patch orientation discrimination task and propose a Continuous Perceptual Awareness Scale (C-PAS) that aims to combine their advantages. The results of the study shown no differences in sensitivity between the scales. However, we observed differences between the scales in awareness ratings frequencies and accuracy associated with the lowest ratings. We concluded that visibility ratings are often biased, and thus, the scale sensitivity may not be optimal. Furthermore, based on the additional analyses, we argued that there is an advantage of using C-PAS over CS. The scale allows to use an additional variability of judgment within PAS categories and thus it may enable more fine-grained measurement of visibility at near-threshold conditions.     

The processing of non-target words: Semantic or not?

It is known that people reacting to visual words may be affected by the meaning of accompanying non-target words. On the approach to perception developed by Treisman (e.g. 1986), this is surprising, because meaning might be thought to require analysis of conjunctions of physical features and so should remain uncomputed for non-target words. Treisman's approach does, however, assert that analysis of the target may unleash further processes that would prime the system for detection of related words. If this were so, then presentation of the target earlier than the distractors would increase the effect of the latter; whereas if analysis of non-targets were independent of priming, they might be expected to have a smaller effect when delayed. Further, if the sets of words involved are small and familiar, then individual features of primed non-targets, rather than conjunctions of features, might trigger interference. They might especially do so when spatial separation of target and non-target is small.

Five experiments using a paradigm developed by Shaffer and LaBerge confirm that the meaning of non-target words affects response to targets; but (1) this is more true for early than for late arrival of the target; (2) it is affected by target/non-target separation in space; (3) it is true for familiar sets of repeated words but not, in these data, for words used once only in the experiment. It is therefore concluded that the results are more consistent with a Treisman type of explanation than with a theory of universal and automatic full analysis.     

What makes an event: Temporal integration of stimuli or actions?

In this article, we ask what serves as the “glue” that temporarily links information to form an event in an active observer. We examined whether forming a single action event in an active observer is contingent on the temporal presentation of the stimuli (hence, on the temporal availability of the action information associated with these stimuli), or on the learned temporal execution of the actions associated with the stimuli, or on both. A partial-repetition paradigm was used to assess the boundaries of an event for which the temporal properties of the stimuli (i.e., presented either simultaneously or temporally separate) and the intended execution of the actions associated with these stimuli (i.e., executed as one, temporally integrated, response or as two temporally separate responses) were manipulated. The results showed that the temporal features of action execution determined whether one or more events were constructed; the temporal presentation of the stimuli (and hence the availability of their associated actions) did not. This suggests that the action representation, or “task goal,” served as the “glue” in forming an event in an active observer. These findings emphasize the importance of action planning in event construction in an active observer.     

To cross or not to cross: Impact of visual and auditory cues on pedestrians’ crossing decision-making

The controlled study of pedestrians’ crossing decision-making is relevant to the search for better safety conditions for this class of vulnerable road users. Several risk factors have been identified in the literature related to the crosswalks’ surrounding environment, the socio-demographic characteristics of the pedestrians crossing the road and the place where the crosswalks are inserted, as well as situational variables, such as speed and distance of the approaching vehicle during the crossing. In this work, the roles of visual and auditory cues in crossing decisions were analysed, comparing different speeds and distances, and taking into consideration different speed patterns of the approaching vehicle, aiming to identify what can affect pedestrians’ crossing behaviour. Experiments were performed in a virtual environment. Participants were presented with 10 different stimuli featuring a vehicle approaching with different speeds and movement patterns, combined with 2 auditory conditions: one concerning a vehicle with a gasoline combustion engine and another one with no sound cues. Participants were tasked with indicating the moment they decided to cross the street when they thought it was safe to do so by pressing a response button. Percentage of crossings, response time (RT), and time-to-passage (TTP) were recorded and subsequently analysed. The results showed that lower speeds and higher distances lead to higher percentages of crossings and RTs. The auditory condition did not significantly affect participants’ responses, leading to the conclusion that participants’ crossing decision was especially based on their visual perception of the movement characteristics of the approaching vehicle, particularly its speed and distance. These results may have relevance for the development of communication strategies between the vehicles, especially the automated ones, and pedestrians.     

Are my cues better than your cues?| Uniqueness and reconstruction as prerequisites for optimal recall of verbal materials

Three experiments are presented to demonstrate a striking empirical phenomenon not previously reported in the literature. This new phenomenon is that of perfect recall performance after incidental learning instruction with one trial only. The means taken to establish this effect was to have subjects generate aspects of each item presented at study and then at test to ask subjects to recall these to-be-remembered items when the selfgenerated aspects were re-presented. The phenomenon was first demonstrated in Experiment 1 and then replicated in Experiments 2 and 3. A few critical controls were also employed in these latter experiments. A tentative, theoretical interpretation of these findings reported was proposed. The core concepts of this interpretation are those of uniqueness and reconstruction.     

Ressourcement or Aggiornamento? An Assessment of Modern Liturgical Reforms

This article assesses the liturgical reforms attributed to Alexander Schmemann and New Skete monastery. A close examination of these reforms demonstrates that they were primarily pastoral attempts to continue the work inaugurated by the Moscow Council of 1917–18 (Schmemann), and to restore monastic stewardship of venerable liturgical traditions (New Skete). The author suggests that it would be more fruitful to approach the question of renewing tradition on the basis of the goals of liturgical renewal, which happen to be common to both the Catholic and Orthodox churches, namely liturgical theosis, or divinization of the people through liturgical events.
