The interaction between schizotypy and latent inhibition: modulation by experimental parameters

Two recent experiments (Della Casa et al., in press) yielded the typical reduced latent inhibition (LI) in high vs low schizotypy subjects after a slow, irregularly presented masking task (Stroop task), and reduced LI in low vs high schizotypy subjects after a fast, regularly presented masking task. The present experiment was aimed at testing whether speed or regularity was responsible for the different results. The present slow, regular experiment replicated the results of the former slow, irregular experiment, i.e. reduced LI in high schizotypals and significant LI in low schizotypals, indicating that speed and not regularity is the critical experimental variable. The modulation of the schizotypy—latent inhibition relationship can be attributed to differences in attentional resources or the time available to process the to-be-target stimuli during preexposure, in accordance with the hypothesis of Lubow and Gewirtz, 1995 that automatic processing of these stimuli is critical for the development of latent inhibition in adult humans. In addition, results on Stroop and negative priming effects are presented.     

Testing emotional memories: does negative emotional significance influence the benefit received from testing?

A large body of research shows that emotionally significant stimuli are better stored in memory. One question that has received much less attention is how emotional memories are influenced by factors that influence memories after the initial encoding of stimuli. Intriguingly, several recent studies suggest that post-encoding factors do not differ in their effects on emotional and neutral memories. However, to date, only detrimental factors have been addressed. In the present study, we examined whether emotionally negative memories are differentially influenced by a well-known beneficial factor: the testing of memories. We employed a standard cued recall testing-effect paradigm where participants studied cue-target pairs for negative and neutral target pictures. In a subsequent post-encoding phase, one third of the cue-target pairs were tested and one third restudied; the remaining third served as control pairs. After one week, memory for all cue-target pairs was tested. While replicating both the testing effect and the emotional enhancement effect, no differences between negative and neutral memories in the benefits received from testing and restudying were observed. Thus, it seems to be true that post-encoding factors do not influence emotional memories in any other way than neutral memories, even when they are beneficial.     

Cultural Effects Rather Than a Bilingual Advantage in Cognition: A Review and an Empirical Study

The bilingual advantage hypothesis contends that the management of two languages in the brain is carried out through domain‐general mechanisms, and that bilinguals possess a performance advantage over monolinguals on (nonlinguistic) tasks that tap these processes. Presently, there is evidence both for and against such an advantage. Interestingly, the evidence in favor has been thought strongest in children and older adults, leading some researchers to argue that young adults might be at peak performance levels, and therefore bilingualism is unable to confer an improvement. We conducted a large‐scale review of the extant literature and found that the weight of research pointed to an absence of positive evidence for a bilingual advantage at any age. We next gave a large number of young adult participants a task designed to test the bilingual advantage hypothesis. Reasoning from the literature that young adults from an East Asian (Korean) culture would likely outperform those from a Western (British) culture, we also compared participants on this factor. We found no evidence for a bilingual advantage but did find evidence for enhanced performance in the Korean group. We interpret these results as further evidence against the bilingual advantage hypotheses.     

On the nature of international sales and sales management research: a social network–analytic perspective

This research uses a combination of text mining, co-word analysis, and social network analysis (SNA) to review 132 international sales and sales management (ISSM) articles published between 1980 and 2017. The study provides a unique view of the past and future of ISSM research and provides three principal contributions. First, from a social network–analytic perspective, it offers a unique examination of the ways ISSM research topics are interconnected, as reflected by keyword network structure. Second, by conducting SNA across two periods (1980–1999 and 2000–2017) and examining the changes in network centrality measures, the study offers initial insights into the evolving nature of the ISSM literature. Third, the study reports keyword network disconnections (i.e., structural holes) to propose a fruitful agenda for future ISSM research. Taken together, this research offers a current perspective of the ISSM research domain's evolving nature.     

Learning Painting Styles: Spacing is Advantageous when it Promotes Discriminative Contrast

Repetitions that are distributed over time benefit long‐term retention more than when massed. Recent research has suggested that the advantage of spacing may extend to induction learning‐‐learners were better able to identify the artists of previously unseen paintings when, during training, artists' paintings were spaced (paintings by different artists were interleaved) rather than massed (a given artist's paintings were blocked and presented consecutively). Increasing temporal spacing between paintings while maintaining a presentation sequence that was blocked by artist produced test performance no better than massed presentation (both worse than interleaved presentation) (Experiment 1). Displaying paintings by different artists simultaneously produced test performance as good as interleaved presentation and better than massed presentation (Experiment 2). Our findings argue that spacing benefits perceptual induction learning not because of increased temporal spacing per se but rather because interleaving paintings by different artists enhances discriminative contrast between the artists' styles.

不确定性决策违背“确定事件原则”的心理机制再探

不确定性决策违背＂确定事件原则＂的心理机制再探从决策理由切入,在现实情境中考察了违背确定事件原则（sure-thing principle）的心理机制,检验了基于理由（reason-based）的假设。研究结果表明,违背确定事件原则的被试在不确定条件下知觉到的理由冲突程度显著高于遵循确定事件原则的被试在不确定条件下知觉到的理由冲突程度;违背确定事件原则的被试在不确定条件下知觉到的理由清晰程度显著低于其在两种确定条件下知觉到的理由清晰程度,而遵循确定事件原则的被试在不确定条件下知觉到的理由清晰程度则介于其在两种确定条件下知觉到的理由清晰程度之间。研究结果支持了基于理由的假设。     

Affective responses to movie posters: differences between adolescents and young adults

Although the link between cognition and affect in the advertising context has been demonstrated in several studies, no research to date has considered adolescents’ affective responses to movie posters and their attitudes to negative and positive images. A 2 (between subjects) × 4 (within subjects) mixed‐factorial experiment design comprising two groups of subjects (80 adolescents and 80 young adults) and four advertising stimuli (two highly positive images and two highly negative images) was used to test the differences in the subjects’ attitudes to advertising, positive and negative affect, and viewing intentions. Although the adolescents, compared to the young adults, did not appear to have significantly stronger attitudes to emotional advertisements (ads), they showed a similar level of intensity of affective response when exposed to negative and positive images.     

Selective Self-Categorization: Meaningful Categorization and the In-Group Persuasion Effect

ABSTRACT

Research stemming from self-categorization theory (Turner et al., 1987 Turner, J. C., Hogg, M. A., Oakes, P. J., Reicher, S. D. and Wetherell, M. 1987. Rediscovering the social group: A self-categorization theory, Oxford, , England: Basil Blackwell. [Crossref] , [Google Scholar]) has demonstrated that individuals are typically more persuaded by messages from their in‐group than by messages from the out-group. The present research investigated the role of issue relevance in moderating these effects. In particular, it was predicted that in-groups would only be more persuasive when the dimension on which group membership was defined was meaningful or relevant to the attitude issue. In two studies, participants were presented with persuasive arguments from either an in-group source or an out-group source, where the basis of the in-group/out-group distinction was either relevant or irrelevant to the attitude issue. Participants' attitudes toward the issue were then measured. The results supported the predictions: Participants were more persuaded by in-group sources than out-group sources when the basis for defining the group was relevant to the attitude issue. However, when the defining characteristic of the group was irrelevant to the attitude issue, participants were equally persuaded by in-group and out-group sources. These results support the hypothesis that the fit between group membership and domain is an important moderator of self-categorization effects.     

Locus of Control and Cooperative Behavior in 10-Year-Old Children

Abstract

A game-like task was used to evaluate the cooperative behavior of 10-year-old same-sex dyads that were paired homogeneously or heterogeneously on a premeasure of locus of control. Pairs of girls were relatively more cooperative than were boys, and dyads of internal locus of control boys who displayed relatively little cooperation on initial trials became more cooperative as the game progressed. In addition, male dyads heterogeneous in terms of locus of control (an internal and an external), who also displayed little cooperation initially, became even less cooperative over trials.
