Redundant sensory information does not enhance sequence learning in the serial reaction time task

In daily life we encounter multiple sources of sensory information at any given moment. Unknown is whether such sensory redundancy in some way affects implicit learning of a sequence of events. In the current paper we explored this issue in a serial reaction time task. Our results indicate that redundant sensory information does not enhance sequence learning when all sensory information is presented at the same location (responding to the position and/or color of the stimuli; Experiment 1), even when the distinct sensory sources provide more or less similar baseline response latencies (responding to the shape and/or color of the stimuli; Experiment 2). These findings support the claim that sequence learning does not (necessarily) benefit from sensory redundancy. Moreover, transfer was observed between various sets of stimuli, indicating that learning was predominantly response-based.     

Do we need a new theory of truthmaking? Some comments on Disjunction Thesis, Conjunction Thesis, Entailment Principle and explanation

In the paper we discuss criticisms against David Armstrong’s general theory of truthmaking by Gonzalo Rodriguez-Pereyra, Peter Schulte and Benjamin Schnieder, and conclude that Armstrong’s theory survives these criticisms. Special attention is given to the problems concerning Entailment Principle, Conjunction Thesis, Disjunction Thesis and to the notion of explanation.     

Heidegger and the Problem of Idealism

This paper contains a discussion of Quine's thesis of indeterminacy of translation within the more general thesis that using and understanding a language are to be conceived of as a creative and interpretative‐constructional activity. Indeterminacy is considered to be ineliminable. Three scenarios are distinguished concerning, first, the reasons for indeterminacy, second, the kinds of indeterminacy and, third, different levels of a general notion of recursive interpretation. Translational hypotheses are seen as interpretational constructs. The indeterminacy thesis turns out to be a consequence of the externalizing of language, meaning, and epistemology. By means of a three‐leveled interpretation model one can substantiate the crucial aspects, first, that indeterminacy is not an indeterminacy of facts of the matter and, second, that there is a significant difference between indeterminacy and underdetermination. In addition, the relationship between indeterminacy, interpretation, and charity is elucidated. Indeterminacy is seen not as an obstacle to but as a condition for communication. Charity and empathy in dialogue are conditional upon indeterminacy. All three components reveal the interpretative‐constructional character of the inseparable connection of meaning and experience.     

Does the Brain Differentiate Between Related and Unrelated Cuts When Processing Audiovisual Messages? An ERP Study

The purpose of this study is to test the hypothesis that during audiovisual message processing (e.g., television or film), cuts in the video track cause an orienting response, which is reflected in the involuntary shift of attention. In classic research by Reeves et al. (1985) Reeves, B., Thorson, E., Rothschild, M. L., McDonald, D., Hirsch, J. and Goldstein, R. 1985. Attention to television: Intrastimulus effects of movement and scene change on alpha variation over time. International Journal of Neuroscience, 27: 241–255. doi:10.3109/00207458509149770[Crossref], [PubMed], [Web of Science ®] , [Google Scholar], changes in the alpha band were noticed in reaction to montage cuts. We propose an investigation of the brain's reaction to montage cuts by means of event-related potentials (ERPs), which are the brain's electrophysiological responses to a stimulus. Well-known indices of orienting response are two ERP components: P3 and slow cortical potential (SCP). Ten participants watched a film consisting of 105 related and 114 unrelated cuts while an electroencephalographic signal was recorded. The hypothesis that unrelated cuts in the video track when watching an audiovisual message cause more pronounced SCP was confirmed. There was no effect of unrelated cuts on P3. The results of this study provide a good starting point for further research on brain reactions to the structural features of an audiovisual message, such as close ups or camera moves.     

Psychological profile of Polish skydivers

To identify personality factors, personal values, time perspective, and attitude toward death of 53 Polish skydivers (M age = 28.4 yr., SD = 9.8) and 59 low-risk sport athletes (controls, M age = 27.3 yr., SD = 5.3), several scales were used. These were the Zuckerman-Kuhlman Personality Questionnaire, Schwartz's Value Survey, the Present and Future Time Perspective Questionnaire, and Death Attitude Questionnaire. It was found that skydivers scored higher on Impulsive Sensation Seeking, Hedonism, Stimulation, and Self-direction values, concentration on the present, preferring a fast death, and belief about controlling death in comparison to the control group. Skydivers also scored lower on Tradition, Universalism, and Benevolence values in comparison to the control group.     

Increasing stimulus intensity does not affect sensorimotor synchronization

When people synchronize taps with isochronously presented stimuli, taps usually precede the pacing stimuli [negative mean asynchrony (NMA)]. One explanation of NMA [sensory accumulation model (SAM), Aschersleben in Brain Cogn 48:66–79, 2002] is that more time is needed to generate a central code for kinesthetic-tactile information than for auditory or visual stimuli. The SAM predicts that raising the intensity of the pacing stimuli shortens the time for their sensory accumulation, thereby increasing NMA. This prediction was tested by asking participants to synchronize finger force pulses with target isochronous stimuli with various intensities. In addition, participants performed a simple reaction-time task, for comparison. Higher intensity led to shorter reaction times. However, intensity manipulation did not affect NMA in the synchronization task. This finding is not consistent with the predictions based on the SAM. Discrepancies in sensitivity to stimulus intensity between sensorimotor synchronization and reaction-time tasks point to the involvement of different timing mechanisms in these two tasks.     

Ordinary life and the tragedy of solidarity

In his texts, Józef Tischner (1930–2000) referred to significant problems characteristic of the end of the communist regime and the first years of the liberal-democratic system in Poland. He tried to understand, among other things, the sources of Polish society’s disappointment with their regained political and economic freedom. This article discusses the late period of Tischner’s life and work, when his philosophy was heavily influenced by the ideas of Charles Taylor. On the one hand, the author analyzes Tischner’s attitude toward the concept of ordinary life, while on the other, Tischner’s understanding of solidarity combined with the concept of the spirit of capitalism. The article shows numerous similarities and significant differences between the way of thinking of both philosophers. The former concern above all the consentaneous assessment of the disappearance of heroism in liberal-democratic societies, while the latter concern the discrepancies in the assessment of the possibility of fully implementing the idea of solidarity in these societies.

     

Effects of repetition priming on recognition memory: testing a perceptual fluency-disfluency model

Five experiments explored the effects of immediate repetition priming on episodic recognition (the "Jacoby-Whitehouse effect") as measured with forced-choice testing. These experiments confirmed key predictions of a model adapted from D. E. Huber and R. C. O'Reilly's (2003) dynamic neural network of perception. In this model, short prime durations pre-activate primed items, enhancing perceptual fluency and familiarity, whereas long prime durations result in habituation, causing perceptual disfluency and less familiarity. Short duration primes produced a recognition preference for primed words (Experiments 1, 2, and 5), whereas long duration primes produced a preference against primed words (Experiments 3, 4, and 5). Experiment 2 found prime duration effects even when participants accurately identified short duration primes. A cued-recall task included in Experiments 3, 4, and 5 found priming effects only for recognition trials that were followed by cued-recall failure. These results suggest that priming can enhance as well as lower familiarity, without affecting recollection. Experiment 4 provided a manipulation check on this procedure through a delay manipulation that preferentially affected recognition followed by cued-recall success.     

Unconscious Emotion

Abstract— Conscious feelings have traditionally been viewed as a central and necessary ingredient of emotion. Here we argue that emotion also can be genuinely unconscious. We describe evidence that positive and negative reactions can be elicited subliminally and remain inaccessible to introspection. Despite the absence of subjective feelings in such cases, subliminally induced affective reactions still influence people's preference judgments and even the amount of beverage they consume. This evidence is consistent with evolutionary considerations suggesting that systems underlying basic affective reactions originated prior to systems for conscious awareness. The idea of unconscious emotion is also supported by evidence from affective neuroscience indicating that subcortical brain systems underlie basic "liking" reactions. More research is needed to clarify the relations and differences between conscious and unconscious emotion, and their underlying mechanisms. However, even under the current state of knowledge, it appears that processes underlying conscious feelings can become decoupled from processes underlying emotional reactions, resulting in genuinely unconscious emotion.
