The irrelevant sound effect: What needs modelling, and a tentative model

This paper reviews the literature on the irrelevant sound effect and concludes that, contrary to some claims, the data consistently show that irrelevant sound and articulatory suppression are not functionally equivalent. We evaluate the contribution of Larsen and Baddeley (2003 in this issue) and briefly discuss additional data in support of their position. We perform an error analysis on data from their third experiment and simulate detailed aspects of those data using our primacy model of immediate serial recall. Our model is briefly related to a number of findings in the literature on irrelevant sound.     

“Never Again War”

This essay addresses the complexities of the Roman Catholic position on war by evaluating recent documentary evidence, attending to the contemporary challenges of terrorism and humanitarian interventions. It presents two arguments. First, attending to traditional Catholic resources for assessing war, papal criticism of recent military action, and debates about a recent shift in Catholic just war logic, this essay argues that Catholic teaching on war has undergone a repositioning in a pacifist direction. Second, it contends that recent critiques of this shift in position by scholars such as George Weigel and James Turner Johnson, however, are wrong to categorize this a “functional pacifism.” Though a development from within just war theory and pacifist reasoning, the Church's new stance does not operate as a type of pacifism, allowing too many possibilities for justified armed conflict to be labeled as “functional” pacifism. The essay concludes by examining the traditional Catholic theological commitments that place limits on any movement toward pacifism, precluding even a functionally pacifist position.     

Victim's Response And Alcohol-Related Factors As Determinants Of Women's Responses To Violent Pornography

Women suffer a variety of detrimental effects from exposure to violent pornography. This study examined the role of specific situational cues embedded within a violent pornographic story, as well as alcohol consumption and alcohol expectancies, to determine potential mechanisms through which these effects occur. Female social drinkers ( N = 123), recruited from the community at large, participated in a between-subjects factorial experiment varying two situational cues—victim response (pleasure vs. distress) and story character beverage consumption (alcohol vs. mineral water)—and participant beverage consumption (alcohol vs. placebo vs. tonic). Results indicate that participants' identification with the victim plays a key role in affecting their responses and that alcohol-related factors appear to exacerbate the negative impact of pornography.     

Strategic control of sentence context effects in a naming task

This paper reports an experiment that demonstrates strategic influences on sentence context effects in a naming task. The size of the sentence context effect is shown to be influenced by the validity of the contextual information. A similar result is obtained simply by changing the proportion of validly completed sentences in the practice session without altering the composition of the experimental trials themselves. The manipulation of context validity was found to have its effect largely on the facilitatory component of the context effect. This dissociation of facilitation and inhibition is shown to be contrary to the predictions of attentional accounts of priming but in line with an explanation of contexts effects based on a mechanism that has evolved primarily to resolve lexical and perceptual ambiguity (Norris, 1986). In a further experiment it is shown that the facilitatory effects of sentence context observed in Experiment 1 are not dependent on the particular baseline condition employed.     

Mediation Analysis in Social Psychology: Current Practices and New Recommendations

A key aim of social psychology is to understand the psychological processes through which independent variables affect dependent variables in the social domain. This objective has given rise to statistical methods for mediation analysis. In mediation analysis, the significance of the relationship between the independent and dependent variables has been integral in theory testing, being used as a basis to determine (1) whether to proceed with analyses of mediation and (2) whether one or several proposed mediator(s) fully or partially accounts for an effect. Synthesizing past research and offering new arguments, we suggest that the collective evidence raises considerable concern that the focus on the significance between the independent and dependent variables, both before and after mediation tests, is unjustified and can impair theory development and testing. To expand theory involving social psychological processes, we argue that attention in mediation analysis should be shifted towards assessing the magnitude and significance of indirect effects.
