Differences between digit naming and number word reading in a flanker task

Numbers can be represented as number words or as digits, but are the two notations processed differently? Two experiments in which a flanker paradigm with a naming task was used were conducted, with digits and number words as targets and flankers. Reaction times were shortest when the flanker denoted the same numerical value as the target. The numerical distance between the target and a numerically different flanker modulated reaction times in all conditions, except for number word targets with digit flankers. The direction of this effect—targets were named faster when the flanker was numerically close than when it was far—indicates that the numerical magnitude representations of numbers are associatively connected. When the target and the flanker were presented in the same format, no difference was observed in the distance effects for the two formats. This indicates that number words activate the abstract representation of their numerical value in a way that is very similar to that for digits.     

Automaticity in clinical psychology.

The authors provide an overview of the literature on the ability of response expectancies to elicit automatic responses in the form of self-fulfilling prophecies and link it to the broader psychological investigation of automatic processes. The authors review 3 areas of research in which response expectancies have been shown to affect experience, behavior, and physiology: placebo effects, the effects of false biofeedback on sexual arousal, and the alteration of perceptual and cognitive functions by hypnotic and nonhypnotic suggestion. Also reviewed are data suggesting that all behavior, including novel and intentional behavior, is initiated automatically. Following this review, the authors summarize some of the ways in which knowledge of response expectancy effects and other automatic processes that influence experience and behavior can enhance clinical practice.     

Dissociative identity disorder and the sociocognitive model: recalling the lessons of the past.

In a recent article in this journal, D. H. Gleaves (1996) criticized the sociocognitive model (SCM; N. P. Spanos, 1994) of dissociative identity disorder (DID) and argued in favor of a posttraumatic model (PTM) in which DID is conceptualized as a consequence of childhood abuse and other traumatic events. The present authors demonstrate that (a) many of Gleaves's arguments were predicated on misunderstandings of the SCM, (b) scrutiny of the evidence regarding the psychopathology and assessment of DID raises questions concerning the PTM's conceptual and empirical underpinnings, (c) the treatment literature suggests that iatrogenic factors play an important role in the etiology of DID, and (d) the evidence linking child abuse to DID is more problematic than implied by Gleaves. The present authors conclude that Gleaves's analysis underemphasized the cultural manifestations of multiple role enactments and that the history of DID imparts a valuable lesson to contemporary psychotherapists.     

Family matters The descendants of Freud and Jung

A brief history of what it has meant to be a Jungian analyst and/or analytical psychologist in the United States and England is portrayed. At first the differences between psychoanalysis and analytical psychology were very great, and there was great animosity between the two schools. The conflict was much stronger in the United States than in England where Jungians developed a much better rapport with psychoanalysis. Recent theoretical developments within psychoanalysis, such as the development of self theory and intersubjectivity, as well as speaking about religious issues in a new way, have brought psychoanalysis closer to analytical psychology. On the other hand, analytical psychology has been enriched by an increased awareness of the importance of developmental issues and transference and countertransference. The implications for both psychoanalysis and analytical psychology are explored.     

Expectancy versus absorption in the prediction of hypnotic responding

The Absorption Scale, a measure of imaginative involvement, was administered to 64 subjects in the context of a hypnosis experiment and to an additional 64 subjects in a context unrelated to hypnosis. Expectancies of responding to hypnotic suggestions were assessed both before trance induction and after trance induction but before administration of hypnotic test suggestions. Hypnotic depth was assessed on the Long Stanford Scale (LSS) before the administration of test suggestions, and on the Inventory of Hypnotic Depth (IHD) after the hypnosis session. Absorption was correlated with hypnotic responsivity and expectancy, but only when assesed in the hypnotic context. Completing the Absorption Scale in a hypnotic context appeared to affect hypnotic responsiveness by altering subjects' expectancies. Only postinduction expectancies were uniquely predictive of response to hypnotic test suggestions, and all variables except the LSS were predictive of IHD scores. Results of path analysis supported the hypothesis that trance inductions alter expectancies for responding to hypnotic suggestions and that these altered expectancies determine subsequent hypnotic behavior.     

MECHANISMS OF PLACEBO PAIN REDUCTION:

Abstract— Identical experimental pain stimuli were applied to the right and left index fingers of 56 university students, following the application of a placebo in the guise of a topical anesthetic to one of the fingers. The pain stimuli were administered simultaneously to treated and untreated fingers for half of the subjects and sequentially for the others Significant and equtvalent reductions in pain were reported in both conditions as a function of placebo administration. These data indicate that reductions of experimental pain produced by placebos presented in the guise of local anesthetics are not mediated by such global mechanisms as anxiety reduction or the release of endogenous opioids.     

Inadequate and infrequent are not alike: ERPs to deviant prosodic patterns in spoken sentence comprehension

The current study on German investigates Event-Related brain Potentials (ERPs) for the perception of sentences with intonations which are infrequent (i.e. vocatives) or inadequate in daily conversation. These ERPs are compared to the processing correlates for sentences in which the syntax-to-prosody relations are congruent and used frequently during communication. Results show that perceiving an adequate but infrequent prosodic structure does not result in the same brain responses as encountering an inadequate prosodic pattern. While an early negative-going ERP followed by an N400 were observed for both the infrequent and the inadequate syntax-to-prosody association, only the inadequate intonation also elicits a P600.
