The effect of context variability on source memory

High-context-variability (HCV) items are experienced in many more preexperimental semantic contexts than are low-context-variability (LCV) items. LCV confers an advantage to recognition memory (Steyvers & Malmberg, 2003). In the present study, we tested whether or not that advantage could be causedby enhanced source memory. Both context variability and word frequency were manipulated, and both factors generally affected source monitoring. Accuracy was better for LCV items than for HCV items and better for low- than for high-word-frequency items. We also considered whether context variability exerts its influence at encoding or at retrieval. We concluded that better recognition memory for LCV items was due, in part, to better retrieval of contextual details that specify how an item was originally studied.     

No man is an island: the need to belong and dismissing avoidant attachment style

The need to belong theory proposes that all human beings need social connections. However, dismissive avoidant individuals claim to be comfortable without close relationships and appear to be indifferent to how other people think of them. The current studies examined the association between dismissing avoidant attachment and the desire to feel accepted by others. In Study 1, high-dismissive participants reported experiencing higher than average levels of positive affect and state self-esteem after learning that other participants accepted them. In Study 2, high-dismissive participants felt better about themselves and experienced higher levels of positive affect after learning that in the future they would be successful in interpersonal relative to independent domains or controls. The results of these studies suggest that dismissive avoidants do not represent a counterexample to the hypothesis that all human beings have a fundamental need and desire to belong.     

Capturing focused attention

When attention is diffuse, as in a visual search task, an abrupt onset almost invariably succeeds in capturing attention. But if attention had been cued in advance to a different location, the same onset may then fail to capture attention (Theeuwes, 1991; Yantis and Jonides, 1990). In previous demonstrations, the onset appeared frequently. This may have diminished the onset's novelty, which in turn could have affected its potency in capturing attention. The question we asked was whether preserving the onset's novelty could enhance its capacity in capturing attention, even when attention had been prioritized elsewhere. As in Theeuwes's (1991) study, observers were cued to the target location with a 100%-predictive central arrow cue. The frequency with which visual transients were introduced was varied across experiments. When the onset stimulus appeared frequently (Experiment 1), it indeed failed to capture attention. But when its appearance was relatively infrequent (Experiment 2), capture effects were clearly observed. In Experiment 3, the target appeared in one location throughout the experiment. This would have improved target localization, but an infrequently appearing onset stimulus still successfully captured attention.     

A novel study: investigating the structure of narrative and autobiographical memories

In two experiments we assessed the degree to which memory for events are similar or differ depending on whether they were narrative or autobiographical events. Consistent with previous research on autobiographical memory, memories for events captured the sequential order of events. However, in contrast to autobiographical memory research, ratings of importance did not appear to be related to retrieval speed. An analysis of causal connectivity of the recalled events was significantly related to retrieval speed. Issues of narrative comprehension and memory, autobiographical memory, and their overlap are discussed.     

Enhancing dynamic graphical analysis with the Lisp-Stat language and the ViSta statistical program

Presented is a sample of computerized methods aimed at multidimensional scaling and psychometric item analysis that offer a dynamic graphical interface to execute analyses and help visualize the results. These methods show how the Lisp-Stat programming language and the ViSta statistical program can be jointly applied to develop powerful computer applications that enhance dynamic graphical analysis methods. The feasibility of this combined strategy relies on two main features: (1) The programming architecture of ViSta enables users to add new statistical methods as plug-ins, which are integrated into the program environment and can make use of all the functions already available in ViSta (e.g., data manipulation, editing, printing); and (2) the set of powerful statistical and graphical functions integrated into the Lisp-Stat programming language provides the means for developing statistical methods with dynamic graphical visualizations, which can be implemented as ViSta plug-ins.     

Cognitive colonialism: Nationality bias in Brazilian academic philosophy

This paper presents the results of an experiment designed to test for nationality bias among members of the Brazilian philosophical community. Faculty members and postgraduate students from philosophy departments at seven Brazilian universities evaluated texts attributed to authors of European and Latin American nationalities. Results showed a clear preference for French nationality over Brazilian. They were inconclusive, however, when contrasting other Latin American nationalities with European nationalities, which likely relates to the academic background of the participants. These overall results support the claim that Brazilian academic philosophers are highly critical of Brazilians who produce theories of their own. The paper calls on philosophers to carefully consider the ways in which Eurocentrism impacts their very ability to reason.     

If-Logic and Truth-definition

In this paper we show that first-order languages extended with partially ordered connectives and partially ordered quantifiers define, under a certain interpretation, their own truth-predicate. The interpretation in question is in terms of games of imperfect information. This result is compared with those of Kripke and Feferman.     

‘Zeitgeist’and minority influence—where is the causality: A comment on Clark (1990)

Does the mood of the time (Zeitgeist) facilitate the influence minorities are able to exercise, or is it itself direct product of minority influence? It is argued, from a social psychological definition of the minority–majority relation, that the former interpretation fails to explain many of the observed effects and in particular the conversion effect. A model is offered that is consistent with the second interpretation.     

Synchronic consistency and psychologization in minority influence

The importance of synchronic consistency as a factor facilitating minority influence had not previously been the object of a systematic study. We carried out a 2 × 2 × 2 × 2 experiment aimed at studying the consequences of a) ideological similarity or dissimilarity of two minority sources belonging to b) a single minority or two different ones, on subjects c) ideologically both close and distant from positions defended by the influence sources, d) according to the absence or presence of psychologization. In the main, our hypotheses were confirmed. As expected concerning the ‘close’ subjects, in the absence of psychologization, the similarity and dissimilarity between minority sources take over, respectively, the signification of consistency and inconsistency and, consequently, increase or decrease the influence exerted by the minority sources. Psychologization decreases the benefits of synchronic consistency. Contrariwise, the ‘distant’ subjects did not seem to follow the same ‘logic’: the condition of opinion dissimilarity in the same minority is the most influential; its influence, however, diminishes when the divergence of opinion is explained by means of a psychological dissimilarity. Data related to the image of the sources indicate that the influence process is no longer determined by perceived consistency or inconsistency, but by the objectivity attributed to minorities. Under these circumstances, intra-minority pluralism became the guaranteer of objectivity.     

The cotherapy relationship: Special issues and problems in aids therapy groups

This paper examines the special issues and problems in the co-leadership relationship which arise in ongoing AIDS therapy and support groups. A brief review is given outlining some of the advantages and disadvantages of the coleader model. Specific attention is then paid to the issues/themes of physical deterioration of members, disfigurement, frequent absences, and members dying. Four particular patterns of interaction that develop between cotherapists are identified, illustrated, and discussed.The author thanks the Group Services staff and volunteer therapists for their contributions to this article.
