Sequential tapping interferes selectively with multiple-object tracking: do finger-tapping and tracking share a common resource?

Multiple-object tracking involves simultaneously monitoring positions of a number of target items as they move among distractors. Young adults are capable of tracking only 3-5 items at once. In this study we investigated the origin of this limitation by looking for secondary tasks that interfere with tracking. We compared tracking performance (baseline condition), with performance when participants tapped three fingers in a specific order while tracking (sequential tapping) or articulated three syllables in a specific order while tracking (sequential articulation). The articulation task was used to ensure that the interference produced by sequential tapping was more than would be expected by the executive demands of carrying out any two “attention-demanding” tasks at once. Even though sequential tapping does not require vision or memorizing the positions of external items, it produced significantly more interference than did sequential articulation, as might be expected if tracking and sequential tapping shared a common (limited) resource.     

Prenatal cocaine exposure and infants' preference for novelty and distractibility

The authors used the Fagan Test of Infant Intelligence (J. F. Fagan, L. T. Singer, J. E. Montie, & P. A. Shepherd, 1986) to examine preferences for novelty and to evaluate several indicators of attention (off- and on-task indexes and durations) in 6- and 9-month-old infants who had been prenatally exposed to cigarette smoke only or to cocaine plus other substances. The infants were matched for socioeconomic status. The authors found no group differences in preference for novelty, but the off-task distractibility index and duration were affected by exposure history and showed effects of dosage at the 9-month test time. Infants exposed to cocaine had a higher off-task index and a shorter average off-task look duration than did infants in the other groups. The authors interpreted this pattern of behavior as an indicator of distractibility or stimulation seeking. There were no group differences in measures involving on-task looks or duration at either test time. Correlations between the off-task look index and duration and teratogen use produced moderate correlations at 9 months of age. The authors calculated partial correlations between teratogen exposure and the off-task index at each trimester. Cocaine use during the 1st and 2nd trimesters was significantly correlated with the off-task index at 9 months of age, even when the authors controlled for neonatal measures (e.g., gestational age, birth weight) and during the 1st trimester when they controlled for alcohol and cigarette exposure.     

How Antisocial and Prosocial Coping Influence the Support Process Among Men and Women in the U.S. Postal Service

The influence of antisocial and prosocial copingon the acquisition of social support and on subsequentpsychological distress among 67 male and 47 femalepostal employees was examined allowing genderdifferences in coping to be studied in a single worksetting. Seventy seven percent of the respondents wereEuropean American, 18% were African American, and theremaining 5% were of varying ethnicities including:Asian American and Latin American. Employingstructural equation modeling, women were found to useprosocial coping as a coping response significantly morethan men, and men were found to use antisocial coping as a coping response significantly more thanwomen. Prosocial strategies were related to increasedworkplace social support in both the short-term andlong-term. Antisocial coping strategies were related to less support from co-workers in theshort-term. Contrary to predictions, antisocial copingstrategies were not related to decreased support acrosstime. Finally, increased social support was related to less psychological distress within eachassessment period.     

A comment on Fry's "The role of caring in a theory of nursing ethics

Our response to Sara Fry's paper focuses on the difficulty of understanding her insistence on the fundamental character of caring in a theory of nursing ethics. We discuss a number of problems her text throws in the way of making sense of this idea, and outline our own proposal for how caring's role may be reasonably understood: not as an alternative object of value, competing with autonomy or patient good, but rather as an alternative way of responding toward that which is of value.     

The supervisory relationship in psychotherapy over time

This study investigated changes in the supervisors' and supervisees' perceptions of the supervisory relationship and the extent to which their perceptions were congruent. Salient dimensions of supervision were identified which predict the quality of the relationship. Twelve supervisory dyads involved in predominantly ongoing supervisory relationships completed an adapted Vanderbilt Psychotherapy Process Scale after each supervisory session for 10 consecutive weeks. The participants' perceptions of the supervisory relationships were relatively stable and positive. However, supervisees felt less dependent over time. With that exception, agreement among participants did not change significantly. Supervisors viewed supervisees' participation and increased assertiveness as significant positive elements in assessing the quality of the relationship. Supervisees' greater exploration and dependency was associated with negative ratings by supervisors. Since supervisors selected the supervisees for the study, the results primarily validate their judgments of the components of a positive continuing supervisory relationship.     

Exploring the Roles of Emotions, Motivations, Self-Efficacy, and Secondary Control Following Critical Unexpected Life Events

We examined individuals’ retrospective accounts and personal analyses regarding how their emotional, motivational, and epistemological beliefs coalesced to affect their long-term coping and resilience following a critical life event. Analyses from interviewed subjects who had encountered significant life-changing events revealed three major themes that influenced their decisions, abilities for self-regulation, and life course paths: (1) types of unexpected events, (2) types and intensity of emotional responses to the critical event, and (3) beliefs about primary control (i.e., personal agency and self-efficacy) and mediated control (i.e., external sources of influence). Regarding the extent to which participants experienced resiliency and current satisfaction with their lives, a dominant theme was their ability to see their critical life events as part of a larger tapestry—involving issues of personal and externally mediated controls—that provided a framework for their positive redirections, perceptions of self-efficacy, and abilities for coping and self-regulation.     

“Nothing Short of a Horror Show”: Triggering Abjection of Street Workers in Western Canadian Newspapers

Over the past decade, Canadian media coverage of street sex work has steadily increased. The majority of this interest pertains to graphic violence against street sex workers, most notably from Vancouver, British Columbia. In this article, the authors analyze newspaper coverage that appeared in western Canadian publications between 2006 and 2009. In theorizing the violence both depicted and perpetrated by newspapers, the authors propose an analytic framework capable of attending to the process of othering in all of its complexity. To this end, the authors supplement a Foucauldian analysis of abjection by considering the work of Judith Butler along with Julia Kristeva's conceptualization of abjection. Using excerpts from western Canadian newspapers, the authors illustrate how the media's discursive practices function as triggers for the process of cultural abjection by inscribing street sex workers with images of defilement. The authors argue that newspaper coverage of street sex workers reinforces the inviolability of normalized life by constantly reiterating the horror reserved for abjected bodies.     

ERP evidence for the control of emotional memories during strategic retrieval

Neural evidence for the strategic retrieval of task-relevant ‘target’ memories at the expense of less relevant ‘nontarget’ memories has been demonstrated across a wide variety of studies. In ERP studies, this evidence consists of the ERP correlate of recollection (i.e. the ‘left parietal old/new effect’) being evident for targets and attenuated for nontargets. It is not yet known, however, whether this degree of strategic control can be extended to emotionally valenced words, or whether these items instead reactivate associated memories. The present study used a paradigm previously employed to demonstrate the strategic retrieval of neutral words (Herron & Rugg, Psychonomic Bulletin and & Review, 10(3), 703-–710, 2003b) to assess the effects of stimulus valence on behavioural and event-related potential (ERP) measures of strategic retrieval. While response accuracy and reaction times associated with targets were unaffected by valence, negative nontargets and new items were both associated with an elevated false alarm rate and longer RTs than their neutral equivalents. Both neutral and negative targets and nontargets elicited early old/new effects between 300 and 500 ms. Critically, whereas neutral and negative targets elicited robust and statistically equivalent left parietal old/new effects between 500 and 800 ms, these were absent for neutral and negative nontargets. A right frontal positivity associated with postretrieval monitoring was evident for neutral targets versus nontargets, for negative versus neutral nontargets, and for targets versus new items. It can therefore be concluded that the recollection of negatively valenced words is subject to strategic control during retrieval, and that postretrieval monitoring processes are influenced by emotional valence.     

Strategic influences on recollection in the exclusion task: Electrophysiological evidence

One assumption underlying the use of the exclusion task as part of the process dissociation procedure is that studied items are successfully excluded only when they are recollected. The present study employed event-related potentials (ERPs) to demonstrate that successful exclusion does not necessarily require recollection. In two experiments, the study tasks for to-be-excluded items were identical, but the tasks employed withtarget items differed, giving better memory for these items in Experiment 1 than in Experiment 2. Successfully excluded items elicited the ERP signature for recollection—theleft parietal old/new effect—in Experiment 2 only. These findings indicate that the subjects adopted different retrieval strategies in the two experiments. It is suggested that they made more use of source information about to-be-excluded items in the second experiment than in the first.
