Evidence from a response choice task reveals a selection bias in the attentional cueing paradigm

In a typical attentional cueing paradigm, irrelevant peripheral cues produce early facilitation (fast responses) followed by later inhibition (slow responses) to cued locations. Here we examine whether cues not only influence the speed with which responses are produced, but also impact or bias which location is ultimately selected as requiring a response. Specifically, can cues influence not only the speed with which we respond but also influence the behavior produced? To examine this question, a choice localization task was used in which no targets were presented, and subjects were asked to choose which effector (left hand, right hand) to use in response to a centrally presented tone. Thus, following either a left or right peripheral cue, and then a central tone, subjects were free to respond with either their left or right hand. Early facilitation and later inhibition with this choice procedure were found in both response times and the proportion of responses to the cued and uncued locations. These results suggest that there are processes which initially bias response selection toward cued locations and then subsequently bias response selection away from cued locations.     

Rapid onset and long-term inhibition of return in the multiple cuing paradigm

Inhibition of return (IOR) refers to the finding that targets at cued locations are responded to more slowly than targets at uncued locations when a relatively long temporal interval occurs between the two events. In studies which have examined the time course of IOR (e.g., Samuel & Kat in Psychonomic Bulletin & Review, 10, 897-906, 2003), the effect is generally shown to develop at around 200 ms and dissipate at around 3,000 ms following a cue. A number of recent studies, however, have demonstrated that IOR can develop much more quickly (up to 50 ms following a cue) and last much longer (up to 13 min following a cue) in certain tasks. The present study uses the multiple cuing paradigm to determine whether IOR can be observed outside the normally reported temporal boundaries (300-3,000 ms) when attention is shifted very quickly (every 15 ms) or very slowly (every 1,500 ms) throughout the visual field. IOR was observed as quickly as 30 ms following cue onset and as long as 6,000 ms following cue onset. Implications for the role of IOR in visual search are discussed.     

AUTOMATIC RELATIONSHIP–HARM ASSOCIATIONS AND INTERPERSONAL TRAUMA INVOLVING CLOSE OTHERS

Women exposed to violence early in life are at risk of revictimization. The interpersonal schema hypothesis of revictimization proposes that revictimized women will be more likely to hold negative expectations about intimate relationships, including expectations that relationships involve harm, relative to singly or nonvictimized women. To test the interpersonal schema hypothesis, we used the implicit lexical decision task to examine automatic associations between relationship and harm concepts among college women who reported histories of no, single, or multiple types of interpersonal trauma involving close others (e.g., family member, partner). Women exposed to multiple types of interpersonal trauma involving close others showed stronger relationship–harm associations than singly or nonexposed women. Relationship–harm associations predicted the number of interpersonal trauma types (e.g., sexual, physical trauma) involving close others reported by participants, but were unrelated to posttraumatic stress disorder (PTSD) symptoms. Findings suggest that relational schemata held by women exposed to multiple types of interpersonal trauma involving close others include concepts of harm, which may have implications for how multiply victimized women behave in and think about intimate relationships.     

Some Features of Promises and their Obligations

Promises raise two main philosophical problems, one moral and the other conceptual. The moral problem concerns the normative significance of promising: what is the nature and basis of the obligations and rights to which promises typically give rise? The conceptual problem is to say what a promise is: what is involved in making a promise? In this paper I defend three controversial claims about promising. One is about the moral problem of promising, one is about the conceptual problem, and the last one is about the relationship between my conceptual claim and my moral claim. My conceptual claim is that a speaker makes a promise only if he communicates an intention to undertake an obligation to the hearer. (I refer to this as the “Obligation Conception Thesis.”) My moral claim is that the obligations typically attached to promises are such that they can be acquired only by those who communicate an intention to undertake an obligation. (I refer to this as the “Voluntary Obligation Thesis.”) My third claim is that if the Obligation Conception Thesis is true, the Voluntary Obligation Thesis is true.     

Competence and warmth stereotypes prompt mental illness stigma through emotions

Public stigma toward mental illness subgroups (11 mental illness subgroups and 2 subgroups perceived to have mental illness) was examined. Competence and warmth stereotypes were used to predict emotional reactions posited to mediate behavioral inclinations ranging from passive to active harm or facilitation. Fear mediated the relationship between low competence and warmth stereotypes and passive harm. Anger, and to a lesser extent fear, mediated the relationship between low warmth and active harm. Pity mediated the relationship between warmth and active facilitation. Neither envy nor admiration linked stereotypes to behavioral reactions. Results suggest that emotions share motivational direction with behavior, to approach or to avoid, rather than simply sharing valence. Implications for research on stigma toward mental illness subgroups are discussed.     

“I Suck at Everything”: Crime,Arrest, and the Generality of Failure

In this article, we advance the idea that getting arrested amounts to “failing at crime.” And akin to the notion of the generality of deviance—where those who engage in any given form of criminal behavior are also likely to engage in a wide array of other problematic behaviors—we examine whether failing at crime (getting arrested) is associated with other forms of life failure. Using data from multiple waves of the National Longitudinal Study of Adolescent to Adult Health, our results reveal that, independent of one’s level of self-reported criminal behavior and other key potential confounders (IQ and self-control), being arrested is a significant predictor of a host of life failures related to education, employment, relationships, and health. The key implication of our study is that it highlights the need to develop a theory of the “generality of failure.”     

Hand position alters vision by biasing processing through different visual pathways

The present study investigated the mechanisms responsible for the difference between visual processing of stimuli near and far from the observer's hands. The idea that objects near the hands are immediate candidates for action led us to hypothesize that vision near the hands would be biased toward the action-oriented magnocellular visual pathway that supports processing with high temporal resolution but low spatial resolution. Conversely, objects away from the hands are not immediate candidates for action and, therefore, would benefit from a bias toward the perception-oriented parvocellular visual pathway that supports processing with high spatial resolution but low temporal resolution. We tested this hypothesis based on the psychophysical characteristics of the two pathways. Namely, we presented subjects with two tasks: a temporal-gap detection task which required the high temporal acuity of the magnocellular pathway and a spatial-gap detection task that required the spatial acuity of the parvocellular pathway. Consistent with our prediction, we found better performance on the temporal-gap detection task and worse performance on the spatial-gap detection task when stimuli were presented near the hands compared to when they were far from the hands. These findings suggest that altered visual processing near the hands may be due to changes in the contribution of the two visual pathways.
