Valence of distractor words increases the effects of irrelevant speech on serial recall 总被引:3,自引:0,他引:3
Participants memorized target words in silence or while ignoring neutral or valent (positive or negative) distractor words that could be either possessor-relevant or other-relevant. Distractor words impaired recall performance, but valent distractor words caused more disruption than neutral distractors, and negative distractors caused more disruption than positive distractors. The results are problematic for explanations of the irrelevant speech effect within working memory models that do not specify an explicit role of attention in the maintenance of information for immediate serial recall. 相似文献

The present study tested the hypothesis that positive mood facilitates cognitive flexibility in categorization, i.e., positive mood enhances the ability to categorize flexibly at broad and narrow levels contingent on task requirement. The study was a conceptual replication of the 1990 work by Murray, Sujan, Hirt, and Sujan. Unlike the original study, it was carried out on the WWW with some modifications in the procedure. Participants were 29 women and 132 men whose average age was 29 yr. They were put into a positive, negative, or neutral mood using the Velten technique. Mood was measured with standard mood scales. Subjects then listed similarities differences between two entertainment TV shows. Contrary to the prediction, participants in a positive mood did not list a higher number, more diverse, or more unusual similarities and differences between the shows, and they were not faster than participants with neutral or negative moods. It is concluded that the influence of mood on cognitive flexibility needs to be reconsidered. In research, temporal aspects of categorization performance as well as a wider range of mood valences should be taken into account. 相似文献

Research on the relationship between age and depression has not yielded a consistent picture. Approaches emphasizing resilience compete with assumptions of an increased incidence of depressive problems in later life. This study investigated these issues within a research format combining cross-sectional and 8-year longitudinal assessments of depressive tendencies (690 participants, aged 54-77 years). The developmental patterns suggest 2 phases: Relative stability extending to about 70 years and a subsequent increase of depressive tendencies. Antecedent and mediating factors were explored within a broader context of variables (health status, social and economic resources, coping competences, and future perspectives). Differences in time perspective and a disposition of accommodative flexibility predicted subsequent changes in depression and mediated age effects in depressive tendencies. 相似文献

In this article, a modified variant of the Affective Simon Task (AST; De Houwer & Eelen, 1998) is presented as a measure of implicit evaluations of single stimuli. In the AST, the words "good" or "bad" have to be given as responses depending on the color of the stimuli. The AST was combined with an evaluation task to increase the salience of the valence of the presented stimuli. Experiment 1 investigated evaluations of schematic faces showing emotional expressions. In Experiment 2 we measured the valence of artificial stimuli that acquired valence in a game context during the experiment. Both experiments confirm the validity of the modified AST. The results also revealed a dissociation between explicit and implicit evaluations. 相似文献

Conceptualization in incremental-integrative\hb language processing Summary. Language is a versatile instrument in co-operatively solving a construction task. In order to understand instructions given during such a task, objects have to be identified and the type of action to be performed has to be determined. The experiments presented show that the way in which objects and actions are conceptualized depends on the linguistic and the non-linguistic, visually available context. Both kinds of information are processed incrementally in an integrative way. The impact of relevant factors, such as the specificity of verbs and object namings, object properties such as color, size, location and the dynamically determined class to which the object belongs was studied. Conclusions for models of language understanding and language production are drawn and requirements for a grammatical formalism suitable for incremental and integrative processing are formulated. Zusammenfassung. Sprache ist ein wichtiges Instrument bei der kooperativen Lösung einer Konstruktionsaufgabe. Zum Verstehen von Handlungsanweisungen im Rahmen dieser Aufgabe müssen Objekte identifiziert und die Art der Handlung erkannt werden. Es werden empirische Untersuchungen vorgestellt, die zeigen, daß die Konzeptualisierung der Objekte und Handlungen vom sprachlichen und nichtsprachlichen, visuell verfügbaren Kontext abhängt. Beide Arten von Kontextinformation werden inkrementell und integrativ verarbeitet. Dazu wurde der Einfluß einzelner Faktoren wie die Spezifität von Verben und Objektbezeichnungen, Objekteigenschaften wie Farbe, Größe und Position sowie die dynamisch zugewiesene Objektklasse und die Wortstellung der benutzten Sprache untersucht. Es werden Folgerungen für die Modellierung von beiden Richtungen der Sprachverarbeitung, Rezeption und Produktion, gezogen und Anforderungen an einen Grammatikformalismus zur inkrementell-integrativen Satzverarbeitung dargestellt. 相似文献

Cases of acts of solidarity can be divided into at least two groups. Solidarity in a narrow sense of the term refers to what I label project-related solidarity; it is prevalent in the modern world at least as much as it was found in past worlds. In contrast, the philosophical discussions of "solidarity" refer to the altruism and mutuality typically found in close human relationships. This concept of "solidarity" is theoretically unfruitful and even misleading. I propose to abandon the term "solidarity" in order to regain sight of the individual phenomena. When these are taken into consideration, a return to the community is no longer called for. I rather argue that modern societies are perfectly capable of inspiring feelings of loyalty and civic virtues, though not by resorting to the old sources of "solidarity". Modern forms such as free associations, participation and, not least, the existence of a liberal society itself are sufficient. Public discussions of solidarity are additionally distorted by frequent appeals to a normative sense of the term. The argument put forward in this collectivist context that an obligation of solidarity results from gratefulness to the community is not found to be convincing. Individuals are not obliged to be grateful to a nation in a way that would be normatively binding. 相似文献

Investigated the process of personality inference from voice quality using 24 male American stimulus persons who served as subjects in simulated jury discussions. Applying a Brunswikian lens model of the inference process, criteria, distal cues, proximal cues and attributions were measured by independent groups of judges: personality criteria by three peers of each stimulus person and, on the basis of content-masked voice samples, distal voice quality indicator cues by six phoneticians, proximal voice percept by ten naive judges, personality attributions by nine naive judges. Only extroversion attributions correlate significantly with the criterion, replicating earlier findings. For the inference of extroversion, contrary to other traits which apparently cannot be inferred accurately from voice quality, the following conditions are met: (a) the criterion is associated with ecologically valid voice energy cues (vocal effort and dynamic range), (b) these indicator cues are adequately represented as proximal voice percepts (particularly loudness and sharpness), and(c) percept utilization in the judges' inferential strategy corresponds to the association between criterion and distal indicator cues. Path-analytic procedures are used to test empirically the adequacy of the inference model to (a) account for the variance in the attributions, and (b) explain significant correlations between criteria and attributions in terms of mediating variables. 相似文献

Die Frage: sind empirische Theorien falsifizierbar? ist natürlich trivialerweise zu verneinen, falls man Theorien nicht als Mengen von Aussagen, sonden z. B., wie Sneed/Stegmüller, als mengentheoretische Strukturen plus intendierte Anwendungsbereiche auffaßt. Daß die Antwort, zumindest dann, wenn man die Fragestellung auf bestimmte physikalische Theorien einschränkt, auch bei Zugrundelegung der sogenannten Aussagen-Konzeption (statement view) nicht anders lautet, ist hingegen schon weniger trivial — obgleich seit langem bekannt, spätestens nämlich seit Duhems berühmter Argumentation gegen die Möglichkeit eines experimentum crucis. Andererseits beruht eine der derzeit einflußreichsten methodologischen Theorien, die von Popper, gerade auf der gegenteiligen Behauptung. Erst jüngst noch hat Popper seine Falsifizierbarkeits-Annahme, vor allem gegen Kritiken von Lakatos und Putnam, zu verteidigen versucht; die gleiche Intention verfolgen auch zwei Aufsätze von Musgrave. Es erscheint mir daher angebracht, kurz auf das Problem der Falsifizierbarkeit von empirischen Theorien zurückzukommen. Vorweg noch zwei Bemerkungen zur Terminologie: 1) Ich verwende, ohne mich auf den Versuch einer genaueren Explikation einzulassen, den Begriff ?(physikalische) Theorie“ in dem für den statement view geläufigen Sinne, wonach eine (deterministische) Theorie aus einer Menge von allgemeinen (deterministischen Natur-)Gesetzen besteht. Es sei ausdrücklich darauf hingewiesen, daß dies wenigstens partiell dem sonst üblichen Sprachgebrauch zuwider läuft: die ?Theorie des Planetensystems“ und die ?Mondtheorie“, beispielsweise, sind keine Theorien im genannten Sinne, weil sie außer auf allgemeinen Naturgesetzen noch auf spezifischen nicht-gesetzesartigen Annahmen beruhen. Andrerseits dürfte diese Deutung des Begriffs ?Theorie“ zumindest mit derjenigen von Popper übereinstimmen. — 2) Daß eine Aussage bzw. Aussagenmenge T falsifizierbar ist, soll, wie bei Popper, bedeuten, daß Basissätze (wahre oder falsche) existieren, die zusammen mit T eine inkonsistente Satzmenge bilden; m.a.W.: falsifizierbar ist T ?in the simple logical sense of being logically incompatible with some basic statements. It has ‘potential falsifiers’“. Basissätze sind dabei, grob gesagt, als Darstellungen von Beobachtungs-Befunden aufzufassen; Genaueres interessiert hier nur insoweit, als es sich umraum-zeitlich singuläre (Existenz-) Sätze handeln muß. Entsprechend soll schließlich T als falsifiziert gelten, wenn es wahre bzw. anerkannte oder akzeptierte Basissätze gibt, die T widersprechen. (Poppers Forderung, daß diese Basissätze ein reproduzierbares Phänomen beschreiben, also eine — allgemeine — ?falsifizierende Hypothese“ bewähren müssen, kann im vorliegenden Zusammenhang außer Betracht bleiben). 相似文献

This research examines the correspondence between theoretical predictions on vocal expression patterns in naturally occurring emotions (as based on the component process theory of emotion; Scherer, 1986) and empirical data on the acoustic characteristics of actors' portrayals. Two male and two female professional radio actors portrayed anger, sadness, joy, fear, and disgust based on realistic scenarios of emotion-eliciting events. A series of judgment studies was conducted to assess the degree to which judges are able to recognize the intended emotion expressions. Disgust was relatively poorly recognized; average recognition accuracy for the other emotions attained 62.8% across studies. A set of portrayals reaching a satisfactory level of recognition accuracy underwent digital acoustic analysis. The results for the acoustic parameters extracted from the speech signal show a number of significant differences between emotions, generally confirming the theoretical predictions.This research was supported by a grant from the Deutsche Forschungsgemeinschaft (Sche 156/8-5). The authors acknowledge collaboration of Westdeutscher Rundfunk, Cologne, in producing professional versions of actor emotion portrayals, and thank Kurt Balser, Theodor Gehm, Christoph Gierschner, Judy Hall, Ursula Hess, Alice Isen, and one anonymous reviewer for helpful comments and contributions. 相似文献

Empirical attempts to explain the genesis of illusory correlations have been largely confined to the demonstration of biased recall processes, although it has been acknowledged that perception and encoding processes may also contribute to the illusion. In the present research, illusory correlations between person types (a student versus a clerk) and educational attitudes (liberal versus authoritarian statements) are demonstrated under conditions where selective recall processes are highly unlikely. The cognitive bias that gives rise to the illusion is shown to already be effective when the stimulus information is perceived. Interestingly, there are marked interindividual differences between experimental participants. The results are discussed in the context of the literature on illusory correlations. 相似文献
