Visual working memory is disrupted by covert verbal retrieval

If working memory (WM) depends on a central resource—as is posited in some theories, but not in others—it should be possible to observe interference between tasks that share few features with each other. We investigated whether interference with WM for visual arrays would occur, even if the interfering task required neither visual processing nor overt responding. In an auditory-verbal interfering task, a response was to be made if a word was recognized as having come from one of two prelearned lists, but not from the other list. As compared with nonretrieval control conditions, even covert verbal memory retrieval disrupted the storage of visual items held in WM. A second experiment ruled out verbal recoding of the visual arrays as the basis of interference. The results indicate that visual WM and verbal long-term retrieval share a central resource (e.g., attention).     

中文阅读中主题与语意信息在句子加工中的作用

采用移动窗口技术,初步探讨了主题、语意信息在句子早期加工中的作用。结果发现：（１）在中文阅读中,当主题信息比较弱时,对句子的早期加工没有作用;当主题信息比较强时,对句子的早期加工有作用。（２）句子语意信息的加工是即时的。     

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.     

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.     

Operant conditioning of an in vitro CNS-pneumostome preparation of Lymnaea

Operant conditioning of aerial respiratory behaviour and its consolidation into long-term memory in Lymnaea has been previously studied in both intact, freely moving snails and in in vitro preparations made from previously trained snails. Here, we show in previously untrained semi-intact in vitro Lymnaea preparations that aerial respiratory behaviour can also be operantly conditioned. Neither yoked control nor 'run-down' control procedures in these in vitro preparations result in an alteration of aerial respiratory behaviour. Memory in the operantly trained semi-intact preparations persists for at least 1h after training. Intracellular recordings made from RPeD1, one of the 3-CPG neurons and the neuron that initiates CPG activity; show that there are specific changes in central excitatory input to this neuron concurrent with learning and its consolidation into memory. In addition following the acquisition of learning and its consolidation into memory the ability of RPeD1 and VI/J neurons when depolarized to cause a pneumostome opening is significantly decreased. Thus, previously untrained in vitro semi-intact preparations can be used to study changes in neuronal activity in a neuron known to be both necessary for the behaviour and for memory formation.     

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.     

Why do People Disagree? Explaining and Endorsing the Possibility of Partiality in Judgments

The current study examines developing changes in children's intuitions about why disagreements about decisions might occur, focusing on what children understand about partiality and how it may vary depending on the context. Eighty children ages 6 to 13 years old and 20 adults were presented with stories in which there was a disagreement with the judge about who the winner of a contest should be. Participants were asked to generate their own explanations for why the disagreement may have occurred and to evaluate the plausibility of different explanations provided by the experimenter. Even 6-year-olds generated and endorsed partiality as a possible explanation for disagreement, although they did so at a lower rate than older children. A richer understanding of how context influences both the reasons for disagreement and the likelihood of partiality seems to develop over childhood.
