Dynamic states in working memory modulate guidance of visual attention: Evidence from an n-back paradigm

Items held in working memory (WM) can automatically bias attention when they reappear in visual displays. Recent evidence, however, suggests that WM biases of attention may be reduced under certain conditions, for example with increasing memory load. We employed a dual task paradigm to investigate how WM biases are affected by dynamic updating of memory contents. 1-back and 2-back versions of a memory task with colour stimuli were interrupted at intervals by an unrelated visual search task. Reappearance in the search display of the item that was currently active in WM guided attention, while suppressed or inactive items did not. We conclude that the rapid updating of memory contents facilitates the shifting of memory representations into different activity states on a moment-to-moment basis. The finding is consistent with models that propose that only one item can be “active” in WM at any one time to guide attention.     

A Clinical approach to marital problems: Evaluation and management

Abstract

This study reviews two instruments designed to assess marital complaints as related to marital behavior: the Areas of Change Questionnaire (AC) and the Comprehensive Areas of Change Questionnaire (CAC). Although the AC is a reliable measure, it evaluates only 13 of the 29 categories of marital problems (Mead&;Vatcher, 1985) described by Geiss and O'Leary (1981). The CAC was developed to measure all 29 categories. Fifty distressed and 50 nondistressed couples were administered the CAC and the Marital Adjustment Test (MAT: Locke&;Wallace, 1959). The CAC is reliable overall, r=.84 and 20 out of 29 categories are reliable r=.40 or greater. Test-retest reliability was greater than r=.82 for all but one scoring method and for 21 of the 29 categories for all respondents with 2 additional categories stable for men and 2 different categories stable for women. The CAC differentiates distressed from nondistressed couples M=59.96 and 11.74 and individuals M=29.98 and 5.87, respectively. The CAC correlates with the MAT r=? .50 and ? .67 for nondistressed and distressed couples, respectively, when 5 extreme scores were removed from the distressed sample. Clinical utility of the CAC is discussed and further research into the nature of marital complaints is recommended.     

Group Psychotherapy Research Studies That Therapists Might Actually Read: My Top 10 List

Much like a bad marriage, the longstanding split between psychotherapy practitioner and researcher continues, each partner feeling unappreciated by and blaming of the other: Therapists are criticized for not reading research and, in turn, criticize researchers for their pursuit of studies that seem irrelevant to the clinical enterprise. In the present article, the author proposes that a shift in the design of psychotherapy research, away from pure outcome studies to models that focus on process, may serve to bridge the divide. Ten research designs exploring aspects of the process of group psychotherapy are illustrated from the recent literature, with the aim of furthering the dialogue between practitioner and researcher.     

The Structure of Partisan Attitudes: Reexamining Partisan Dimensionality and Ambivalence

The true nature of Americans' party attachments remains an area of enduring controversy. Due to inadequate measures, scholars have argued without resolution as to whether partisanship is unidimensional and bipolar, or rather attitudes towards each party are on separate dimensions. Using more appropriate, psychologically specific, multi-item measures of positive and negative partisan evaluations, however, (1) goes a long way towards settling this problematic debate; and (2) allows for explorations of the heretofore unexamined role of ambivalence in partisanship. I find that partisan attitudes are unidimensional and strongly bipolar and that ambivalence weakens the impact of partisan attitudes in both attitudes and behaviors in predictable ways.     

Can power be self‐legitimating? Political realism in Hobbes,Weber, and Williams

Political realists seek to provide an alternative to accounts of political legitimacy that are based on moral standards. In this endeavor, they face the challenge of how to interpret the maxim that power cannot be self‐legitimating. In this paper, we argue that work by Bernard Williams sheds light on the possible answers to this challenge. While Williams aligns himself with the realist tradition, his account of legitimacy contains an implicit critique of political realism. This is evident, we show, in his rejections of the views of Thomas Hobbes and Max Weber. Williams is not satisfied with Hobbes because he conflates legitimacy and political order, eliminating space for criticizing power. Weber's view, however, offers a non‐moralist standard of legitimacy that has critical purchase. This critical purchase emerges from the demands made on rulers to uphold the values that underlie their legitimation, combined with the ethic of responsibility. The resulting grounds for criticism are thus consistent with the maxim that power cannot be self‐legitimating—the very maxim that Williams puts at the heart of his realism. By showing that Williams's partial rejection of Hobbes and Weber cannot be sustained only on realist grounds, our analysis clarifies the limits of political realism.     

True and false memory in the absence of perceptual identification

Two experiments are reported in which, after attempting to identify a briefly flashed, masked test word, participants were asked to rate the likelihood that it had been presented in an earlier study list. Even when people were unable to identify such items, they demonstrated an ability to discriminate between those that were studied and those that were not studied; ratings given to studied items were significantly higher than ratings given to nonstudied items. This effect does not appear to be a data-driven phenomenon. In Experiment 1 it was found when the presentation modality was changed from study to test. In Experiment 2 false memory for unidentified items that were related to studied items was shown.     

Assessing depression with the MMPI and MMPI-2

The usefulness of the MMPI (Hathaway & McKinley, 1951 ) and MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) for diagnosing and assessing symptomatic depression has been the subject of considerable debate for a number of years. In this article, we review the relative contributions of the MMPI and MMPI-2 clinical and content scales in predicting depression. Positive predictive power, negative predictive power, and overall classification rate were computed for Scale 2 (D) of the MMPI and MMPI-2 and the Depression content scale (DEP) of the MMPI-2. Scale 2 (D) of both the MMPI and MMPI-2 appears to be moderately accurate in predicting depression. Although some studies suggest that the content scale DEP provides incremental validity over Scale 2 (D) of the MMPI-2, the results of this review indicate that the content scale DEP of the MMPI-2 does not exceed the diagnostic efficiency of Scale 2 in predicting depression.     

Group Psychotherapy Research: Current Status and Future Trends on the Dawn of the New Millennium

For the past two decades, the group psychotherapy research literature has been dominated by the efficacy study. Over this period of time, this laboratory-based work has acquired a number of methodological requisites all aimed at maximizing its internal validity in order that causal inferences can be made with increasing confidence. These very refinements in methodology, however, have led to increasing criticisms regarding the meaningfulness and relevance of the findings to real-world settings. This paper briefly reviews these developments and offers predictions, gleaned from the current literature, about future directions of research. In particular, three areas are highlighted: (1) the development of effectiveness studies, (2) the greater sophistication of process research, and (3) a renewal of the very early interest in group therapy treatment of medical conditions.     

Primacy versus recency in a quantitative model: activity is the critical distinction

Behavioral and neurobiological evidence shows that primacy and recency are subserved by memory systems for intermediate- and short-term memory, respectively. A widely accepted explanation of recency is that in short-term memory, new learning overwrites old learning. Primacy is not as well understood, but many hypotheses contend that initial items are better encoded into long-term memory because they have had more opportunity to be rehearsed. A simple, biologically motivated neural network model supports an alternative hypothesis of the distinct processing requirements for primacy and recency given single-trial learning without rehearsal. Simulations of the model exhibit either primacy or recency, but not both simultaneously. The incompatibility of primacy and recency clarifies possible reasons for two neurologically distinct systems. Inhibition, and its control of activity, determines those list items that are acquired and retained. Activity levels that are too low do not provide sufficient connections for learning to occur, while higher activity diminishes capacity. High recurrent inhibition, and progressively diminishing activity, allows acquisition and retention of early items, while later items are never acquired. Conversely, low recurrent inhibition, and the resulting high activity, allows continuous acquisition such that acquisition of later items eventually interferes with the retention of early items.
