The effect of working memory capacity on conflict monitoring

The conflict adaptation effect, a reduced interference effect upon the detection of a conflict signal (e.g., following an incongruent trial), has been interpreted as evidence for active regulation of top-down cognitive control. We hypothesized that the extent of conflict adaptation should be related to individuals' working memory capacity (WMC), which has been repeatedly demonstrated to reflect the level of cognitive control. Using the Simon task, in Experiment 1, we quantified the conflict adaptation ratio (CAR) transiently as the ratio of the conflict effect following an incongruent trial to the conflict effect following a congruent trial, controlling for the reaction time that often correlates with WMC. We observed that the CAR varied from highly negative with low WMC scores to near-zero with high WMC scores. This result suggests that high WMC individuals, when detecting conflict, adjust the level of cognitive control optimally so that their performance is less susceptible to the presence of a distractor. In Experiment 2, we quantified the CAR in a sustained manner as the ratio of the conflict effect from predominantly incongruent blocks to the conflict effect from predominantly congruent blocks. Again, the CAR varied from negative to zero as WMC increased. These results suggest that WMC may reflect, in addition to the ability to maintain a level of control, the ability to adjust the level of control appropriately to the contextual demands.     

A process-dissociation analysis of semantic illusions

We examine semantic illusions from a dual-process perspective according to which the processes that go into failing or succeeding to detect such illusions can be decomposed into controlled processes (checking the facts in the sentence against the information in memory) and automatic processes (the impression of truth that comes from the semantic associations between the elements in the sentence). These processes, we argue, make largely independent contributions to truth judgments about semantic-illusory sentences. The Process Dissociation Procedure was used to obtain estimates of these two kinds of processes. In Study 1, participants judged whether sentences were true or false while under high or low cognitive load. Cognitive load increased the rate of semantic illusions by specifically affecting controlled processing but not automatic processing. In Study 2, a previous paired-associate learning task also increased the rate of semantic illusions, but it did so by specifically affecting automatic processing, not controlled processing.     

Comparison Blindness

Change blindness has been linked to comparisons over time when visual input is disturbed by a transient. This is most directly seen in “flicker” paradigms where change is invisible when introduced during a blank period between successive presentations of stimuli, and is implicit in paradigms where a stimulus is changed during a saccade. Difficulties in comparing two simultaneously present stimuli have been considered to be due to transaccadic memory limitations in tasks requiring saccades. We present here experiments that demonstrate the phenomenology of change blindness, but in tasks where two stimuli are present in the central visual field within a single fixation and where there are no transients present. These experiments are based on contrast discriminations of patterns composed of a few simple elements. We have found comparisons over space within a single fixation to be as difficult as comparisons over time. As in the more usual paradigms for change blindness, cueing makes changes easy to detect. These results suggest that a memory bottleneck is not essential to produce change blindness.     

Duty and Love

Abstract

The grip and forcefulness of the demands that love imposes upon us resemble the forcefulness and grip of moral obligation. In cases of both kinds, we feel that we are not free to do as we please. It is a mistake, however, to presume that the requirements of love and duty are of the same kind or have the same source.     

Witness to History: Introduction to Symposium on Transhistorical Catastrophe

This paper introduces the symposium on transhistorical catastrophe by illustrating some differences between American relational and French analytic approaches to the study and treatment of trauma. The work of Davoine and Gaudillière is presented to familiarize the reader with their unique and eclectic approach to researching “madness.” Preparing for the dialogue that follows, I briefly present the discussants, who collectively take the discussion of transhistorical catastrophe from psychoanalysis through history, literature, quantum science, and linguistics.     

A Human Family: Commentary on Paper by Elisabeth Fivaz-Depeursinge,Chloé Lavanchy-Scaiola,and Nicolas Favez

In discussing the paradigm shifting work of Fivaz-Depeursinge and her colleagues, I illustrate how developmental conceptions have shifted from a narrative centered on the discovery of “an Other” to narratives emphasizing what these authors term “collective intersubjectivity.” In this latter view, humans simultaneously share affect and intention with multiple others from birth, and subsequently continue to develop increasingly sophisticated means for doing so thorough out their lives. I situate this phenomenon in philosophy, nonlinear dynamic systems theory and evolutionary biology in order to highlight the species specific, phenomenologically given, and ecologically situated aspects of our intersubjective condition. Intersubjectivity from the perspective of Fivaz-Depeursinge and her group opens us to this collective dimension of membership in a human family.     

Predictors and Outcomes of Experiences Deemed Religious: A Longitudinal Investigation

The two studies reported here revised Hunt's (1972) LAM (Literal, Anti-Literal, Mythological) Scale to include a Metaphorical dimension. The first study investigated the relationship between preference for literal versus metaphorical interpretations of religious language and structural levels of religious thinking. As predicted, participants who preferred a literal interpretation of religious statements gave evidence of a low developed structure of religious judgment. The predicted relationship between preference for metaphorical interpretations and style of religious thinking was not found. The second study compared samples of participants scoring highest on the Literal and the Metaphorical subscales. Literal participants scored lower on imaginative thinking and made greater use of religious language in an objectifying manner than did metaphorical participants. The meaning of these data for mature religious thinking is considered.     

“Faith Maturity Scale” for Chinese: A Revision and Construct Validation

Using a large sample of Chinese Christians (n = 2,196), we examined the internal structure, reliability, and validity of the Faith Maturity Scale (FMS). Despite its being developed in North America, and for a mainline Protestant population, the FMS was shown to have validity among non-Western, non-mainline Protestants. There is convergent validity with self-reported religious practices and a belief measure of religiosity. Our analyses also confirmed good construct validity with the Big Five personality dimensions, social axioms, attributional style, and quality of life. FMS remained associated with religious practices and high quality of life after personality was statistically controlled. Findings supported that the Chinese version of the FMS assesses the same theoretical construct as does the original scale and that the distinction between the vertical and horizontal dimensions of faith maturity is meaningful.     

More of myself: Manipulating interoceptive awareness by heightened attention to bodily and narrative aspects of the self

Psychology distinguishes between a bodily and a narrative self. Within neuroscience, models of the bodily self are based on exteroceptive sensorimotor processes or on the integration of interoceptive sensations. Recent research has revealed interactions between interoceptive and exteroceptive processing of self-related information, for example that mirror self-observation can improve interoceptive awareness. Using heartbeat perception, we measured the effect on interoceptive awareness of two experimental manipulations, designed to heighten attention to bodily and narrative aspects of the self. Participants gazed at a photograph of their own face or at self-relevant words. In both experimental conditions interoceptive awareness was significantly increased, compared to baseline. Results show that attention to narrative aspects of self, previously regarded as relying on higher-order processes, has an effect similar to self-face stimuli in improving interoceptive awareness. Our findings extend the previously observed interaction between the bodily self and interoception to more abstract amodal representations of the self.     

Understanding physical activity behavior and cognitions in pregnant women: An application of self-determination theory

ObjectivesAlthough regular exercise during pregnancy is linked with improved health outcomes for both mother and foetus, many pregnant women are inactive. The purpose of this study was to use organismic integration theory (OIT) as the guiding theory for examining the relationship between autonomous and controlled motives for (a) exercise behavior reported over a typical week and barriers to exercise and (b) exercise and stage of pregnancy (i.e., trimester).DesignCross-sectional.MethodsParticipants (N = 75) were pregnant women who completed a multi-component, Internet-based survey.ResultsMultiple regression analyses showed that identified regulation predicted greater exercise behavior and fewer exercise barriers, irrespective of trimester. Further analyses indicated that women in the first trimester reported significantly higher identified regulation compared to women in either second or third trimesters.ConclusionsOverall, these findings reinforce the importance of distinguishing controlled from autonomous exercise motives and demonstrate the tenability of OIT for enhancing our understanding of exercise behavior and barriers during pregnancy.
