Visual working memory depends on attentional filtering

Working memory holds information actively being used in cognitive performance. Two important aspects of working memory are how many items it can hold, and how efficiently it can be used. Recently, Vogel and colleagues used event-related brain potentials to show that these two things are related. People who could remember more objects from a spatial array also more efficiently excluded irrelevant objects. The results raise important questions about what aspect of working memory is most fundamental.     

When do visual and verbal memories conflict? The importance of working-memory load and retrieval

Examinations of interference between verbal and visual materials in working memory have produced mixed results. If there is a central form of storage (e.g., the focus of attention; N. Cowan, 2001), then cross-domain interference should be obtained. The authors examined this question with a visual-array comparison task (S. J. Luck & E. K. Vogel, 1997) combined with various verbal memory load conditions. Interference between tasks occurred if there was explicit retrieval of the verbal load during maintenance of a visual array. The effect was localized in the maintenance period of the visual task and was not the result of articulation per se. Interference also occurred when especially large silent verbal and visual loads were held concurrently. These results suggest central storage along with code-specific passive storage.     

Nipping psychopathy in the bud: an examination of the convergent, predictive, and theoretical utility of the PCL-YV among adolescent girls

Over the last decade rates of violence among adolescent girls have increased. Within high-risk contexts, urgent calls for assessment options have resulted in the extension of adult and male-based instruments to adolescent females in spite of the absence of strong empirical support. The current study evaluates the downward extension of psychopathy within a population of female juvenile offenders (N=125). The convergent and predictive validity of the Psychopathy Checklist-Youth Version (PCL-YV) were evaluated within a structural equation modeling (SEM) framework. Results indicated that while a specific component of psychopathy, deficient affective experience, was related to aggression, the effect was negated once victimization experiences were entered into the models. In addition, PCL-YV scores were not predictive of future offending, while victimization experiences significantly increased the odds of re-offending. Implications for research, policy, and clinical practice are discussed.     

Three steps to open science for qualitative research in psychology

Principles and applications of open science (also referred to as open research or open scholarship) in psychology have emerged in response to growing concerns about the replicability, transparency, reproducibility, and robustness of psychological research alongside global moves to open science in many fields. Our objective in this paper is to inform ways of collectively constructing open science practices and systems that are appropriate to, and get the best out of, the full range of qualitative and mixed-method approaches used in psychology. We achieve this by describing three areas of open research practice (contributorship, pre-registration, and open data) and explore how and why qualitative researchers might consider engaging with these in ways that are compatible with a qualitative research paradigm. We argue it is crucial that open research practices do not (even inadvertently) exclude qualitative research, and that qualitative researchers reflect on how we can meaningfully engage with open science in psychology.     

Sexual and nonsexual marital aggression: Legal considerations, epidemiology, and an integrated typology of perpetrators

In this paper, the legal history of marital rape and the current status of “marital rape allowances” to sexual assault statutes are reviewed. The prevalence of marital rape and its comorbidity with nonsexual violence, as well as the physical and psychological sequelae found to be specifically associated with sexual aggression in marriage is reviewed. Our current limited theoretical understanding of the relationship between sexual and nonsexual violence in marriage is extended by integrating marital rape and marital violence batterer typology research. Specifically, we offer a four-type batterer typology integration (i.e., family-only, dysphoric/borderline, generally violent/antisocial, and sexually obsessive batterers) that fully describe husbands that are only nonsexually violent, both physically and sexually violent, or only sexually violent. Theoretical and practical implications of this integration are identified. Future research directions are outlined, and the need for greater clinical attention to the phenomena of sexual violence in marriage is highlighted.     

Age-related decrement in auditory selective attention

Young (n = 30), middle-aged (n = 32), and old (n = 28) adults repeated (shadowed) words presented to the left ear at 60 words per minute with and without distracter words presented to the other ear. Dichotic shadowing error rate increased with age. An attempt to eliminate the age effect by adjusting for age differences in monaural shadowing errors, fluid intelligence, and pure-tone hearing loss did not succeed. When the analyses were confined to subjects who made no monaural shadowing errors, dichotic shadowing errors still increased linearly with age. These results showed that there are selective-attention deficits in older adults that cannot be accounted for by the uncertainty of the target location.     

On the relationship between category intensions and extensions in children

We contrasted four theories of natural language category acquisition by investigating the relation between category intensions and extensions in children (kindergarteners, second graders, fifth graders) and in college students. Everyone was asked to define a category term, to make category membership judgments of possible exemplars, and to judge whether the possible exemplars possessed features generated by them and by previous adult subjects. Adult judges were also asked to judge whether the possible exemplars possessed the features generated by the subjects. Children's intensions and extensions were very consistent. In addition, children's extensions were reliably smaller than adults', and the features which children generated were more specific than those generated by adults. None of the existing theories discussed can explain this pattern of results. An exemplar-based model is proposed to do so.     

The effects of facial control and facial mimicry on subjective reactions to comedy routines

The impact of facial control on subjective reactions to dubbed (created with inserts of smiling people) and undubbed comedy routines was examined. The presence of dubs increased EMG activity over thezygomaticus major andorbicularis oculi muscle regions for spontaneous-condition subjects, but not for inhibit-condition subjects. Analyses also showed that spontaneous-condition subjects exhibited increased smiling at dub points, a finding that is consistent with the notion that subjects mimicked the inserted facial displays. Self-report findings revealed that spontaneous-condition subjects reported significantly greater amusement to the dubbed compared with the undubbed routines, whereas inhibit-condition subjects' self-reports of amusement did not differentiate dub conditions. Furthermore, spontaneous-condition subjects reported significantly more amusement to the dubbed routines than did inhibit-condition subjects. Despite strong facial control effects on facial EMG activity, no main effect of facial condition on self-reported amusement was found, and therefore, the data provide no support for a general version of facial feedback theory. The data are consistent with the view that mimetic responses enhanced subjective reactions, and they are compatible with the Leventhal and Tomkins versions of facial feedback theory.The research was supported by NSF Grant No. BNS-8507600 and the Lincoln Filene Endowment to Dartmouth College.
