Auditory spatial negative priming: What is remembered of irrelevant sounds and their locations?

The categorization and identification of previously ignored visual or auditory stimuli is typically slowed down—a phenomenon that has been called the negative priming effect and can be explained by the episodic retrieval of response-inadequate prime information and/or an inhibitory model. A similar after-effect has been found in visuospatial tasks: participants are slowed down in localizing a visual stimulus that appears at a previously ignored location. In the auditory modality, however, such an after-effect of ignoring a sound at a specific location has never been reported. Instead, participants are impaired in their localization performance when the sound at the previously ignored location changes identity, a finding which is compatible with the so-called feature-mismatch hypothesis. Here, we describe the properties of auditory spatial in contrast to visuospatial negative priming and report two experiments that specify the nature of this auditory after-effect. Experiment 1 shows that the detection of identity-location mismatches is a genuinely auditory phenomenon that can be replicated even when the sound sources are invisible. Experiment 2 reveals that the detection of sound-identity mismatches in the probe depends on the processing demands in the prime. This finding implies that the localization of irrelevant sound sources is not the inevitable consequence of processing the auditory prime scenario but depends on the difficulty of the target search process among distractor sounds.     

What about the “ups and downs” in our daily life? The influence of affective instability on mental health

Although affective instability is considered to be a crucial factor for mental disorders, research on affective instability and mental health is still rare. The aim of the present study was to investigate affective instability and mental health operationalized by the degree of psychological distress and life satisfaction. Using ecological momentary assessment, we investigated affective intensity and instability in a general population sample (n = 218). Psychological distress and life satisfaction were examined cross-sectionally and longitudinally. In general, we found that positive affect was more variable than negative affect. When we accounted for the overlap between variables, our findings demonstrated that besides the effects of intensity in negative affect and positive affect, higher positive affective instability was related to better concurrent mental health. Longitudinally, negative affective intensity was a decisive factor in the development of mental health. In sum, our findings revealed that affective instability was not dysfunctional per se. In fact, instability in positive affect seems to be important to achieve mental health.     

Visual short-term memory always requires general attention

The role of attention in visual memory remains controversial; while some evidence has suggested that memory for binding between features demands no more attention than does memory for the same features, other evidence has indicated cognitive costs or mnemonic benefits for explicitly attending to bindings. We attempted to reconcile these findings by examining how memory for binding, for features, and for features during binding is affected by a concurrent attention-demanding task. We demonstrated that performing a concurrent task impairs memory for as few as two visual objects, regardless of whether each object includes one or more features. We argue that this pattern of results reflects an essential role for domain-general attention in visual memory, regardless of the simplicity of the to-be-remembered stimuli. We then discuss the implications of these findings for theories of visual working memory.     

Contingency learning and stereotype formation: Illusory and spurious correlations revisited

The ability of implicit measures to predict behaviour varies greatly across studies, emphasising the need for accounts of this variability. In order to organise and review the literature on moderators that influence individuals' information processing, we suggest a classification system of moderators with two dimensions. One dimension distinguishes moderators according to their influence on the opportunity to control, the motivation to control, or the reliance on either automatic or controlled processes without changes in opportunity or motivation. The second dimension classifies moderators according to whether they pertain to a disposition of the acting person, the situation in which the behaviour occurs, or the behaviour itself. Increased predictive validity of implicit measures is associated with conditions that foster the impact of automatic processes on behaviour determination. In the discussion we derive several additional moderators from the classification system, delineate emerging research questions, and discuss implications of the reviewed studies for research on self-regulation.     

New surprises for the Ramsey Test

In contemporary discussions of the Ramsey Test for conditionals, it is commonly held that (i) supposing the antecedent of a conditional is adopting a potential state of full belief, and (ii) Modus Ponens is a valid rule of inference. I argue on the basis of Thomason Conditionals (such as ‘If Sally is deceiving, I do not believe it’) and Moore’s Paradox that both claims are wrong. I then develop a double-indexed Update Semantics for conditionals which takes these two results into account while doing justice to the key intuitions underlying the Ramsey Test. The semantics is extended to cover some further phenomena, including the recent observation that epistemic modal operators give rise to something very like, but also very unlike, Moore’s Paradox.     

65 Jahre später

Research on the long-term emotional impact of World War II experiences is an important psychoanalytical issue and requires an interdisciplinary approach. In the project: “Witnesses of the ‘Operation Gomorrha (Hamburg Firestorm)’ (1943) and their families” long-term processing of and coping with war experiences of former children and adolescents are investigated by historians and psychoanalysts. A sample of 64 witnesses (34 women, 30 men, average age 75 years) and their families was recruited and investigated by semi-structured interviews. The interviews were analyzed by methods of “renarrated and interpreted history of coping” and group analysis against the background of historical, psychological and cultural approaches. A total of nine prototypical cases give insight into different biographically determined representations of the “Firestorm” and the conjunction with socio-cultural processes. Analysis of coping over the life-time has to take life experiences after the war and during the time of rebuilding into account. The research project attracts much interest among the former “war”-children.     

Reliability and validity of the Single‐Target IAT (ST‐IAT): assessing automatic affect towards multiple attitude objects

In contrast to the original Implicit Association Test (IAT), the Single‐Target Implicit Association Test (ST‐IAT) measures the evaluation of a target object without the need to simultaneously evaluate a counter‐category. The present research investigates (a) whether position within a series of several ST‐IATs affects reliability and validity, and (b) whether the ST‐IAT exhibits adequate construct validity if the target objects are closely interrelated. We address these questions by taking five interrelated yet distinct political parties in Germany as an exemplary domain. The ST‐IAT reliably and validly assessed attitudes towards political parties (Study 1). Serial position effects did not affect the results. The ST‐IATs mostly captured a specific party evaluation and exhibited discriminant validity. At the same time, discriminant validity was limited among parties within one wing of the political left–right spectrum that underlies implicit and explicit party evaluations (Study 2). If used with caution, the ST‐IAT can be a valuable supplement to implicit measures in the case of multiple single‐target assessments. Copyright © 2007 John Wiley & Sons, Ltd.     

Working memory capacity and self-regulatory behavior: toward an individual differences perspective on behavior determination by automatic versus controlled processes

In the present research, the authors investigated how individual differences in working memory capacity moderate the relative influence of automatic versus controlled precursors on self-regulatory behavior. In 2 studies, on sexual interest behavior (Study 1) and the consumption of tempting food (Study 2), automatic attitudes toward the temptation of interest had a stronger influence on behavior for individuals who scored low rather than high in working memory capacity. Analogous results emerged in Study 3 on anger expression in a provoking situation when a measure of the automatic personality trait of angriness was employed. Conversely, controlled dispositions such as explicit attitudes (Study 1) and self-regulatory goals (Studies 2 and 3) were more effective in guiding behavior for participants who scored high rather than low in working memory capacity. Taken together, these results demonstrate the importance of working memory capacity for everyday self-regulation and suggest an individual differences perspective on dual-process or dual-system theories of human behavior.

On the different uses of linguistic abstractness: from LIB to LEB and beyond

Linguistic abstractness has been shown to mediate persuasive and attributional effects of communication. The linguistic intergroup bias (LIB) refers to the tendency to describe positive ingroup and negative outgroup behaviors more abstractly than negative ingroup and positive outgroup behavior. Recently, the LIB was shown to reflect to a large extent a linguistic expectancy bias (LEB). Abstract language need not have an ingroup‐serving function, but may be used to communicate expected information in a concise and condensed manner. The present research shows that the reverse may also be true. When the interaction goal is not merely to convey information that is shared anyway because it is typical of the communication target but to transmit unshared information (known to the communicator but new to the recipient), then it may be necessary to express (explain, teach, interpret) unexpected ideas or deviant attitudes in abstract, interpretive terms. The joint operation of both principles was demonstrated within the same experimental task. In communications about East Germans, more abstract predicates were used in typically East German domains (LEB). However, more abstract terms were also used when messages deviated from the recipient's prior attitude. A conceptual framework is proposed to integrate these findings.

Some Benefits of Being an Activist: Measuring Activism and Its Role in Psychological Well-Being

Do activists lead happier and more fulfilled lives than the average person? Two online surveys using a sample of college students (N = 341) and a national sample of activists matched with a control group (N = 718) demonstrated that several indicators of activism were positively associated with measures of hedonic, eudaimonic, and social well‐being. Furthermore, in both studies, activists were more likely to be “flourishing” ( Keyes, 2002 ) than were nonactivists. A third study of college students (N = 296) explored the possible causal role of activism by measuring well‐being after subjects either engaged in a brief activist behavior, a brief nonactivist behavior, or no behavior. Although well‐being did not differ substantially between these three groups, the subjects who did the brief activist behavior reported significantly higher levels of subjective vitality than did the subjects who engaged in the nonactivist behavior. Potential mediators of the relationship between activism and well‐being and the usefulness of these findings are discussed.
