Novelty and processing demands in conceptual combination

In this article, we sought to isolate the processing demands of combining the concepts of modifier‐noun phrases from those of other language comprehension processes. Probe reaction time (RT) was used as an indication of the processing resources required for combining concepts. Phrase frequency (as measured by Google hit rates) was used as a metric of the degree of conceptual combination required for each phrase. Participants were asked to interpret modifier‐noun phrases using a sense‐nonsense decision (Experiment 1) and a phrase meaning access task (Experiment 2). Experiment 2 also used a lexical decision task to activate the word's individual meanings. Regression analyses for both experiments indicated that phrase frequency (indicating novelty) predicts a significant portion of the probe RT variance, such that low‐frequency phrases required more processing resources than high‐frequency phrases, when controlling for associative strength, word frequency, letter length, and lexical‐semantic activation. Overall, this study indicates that conceptual combination requires processing resources beyond those of other language processes.     

Exploring a patient's shift from relative silence to verbal expressiveness: Observations on an element of the analyst's participation

By tracing a portion of close process of a patient's shifts from a relatively silent and inhibited stance to one in which he is beginning to verbalize more about his experience and fantasy, I will illustrate some tensions between the analyst's role as facilitating expressiveness and as occupying a place in the patient's internalized world. Since the analyst's functions as facilitator and as internal object (often an obstacle to the patient's expressiveness) are sometimes in conflict with one another, it is important for the analyst to be able to work internally with this conflict as he works with his patient. Splitting processes between these two functions may provide the analyst with cues related to the patient's and the analyst's resistance to understanding the patient's communication of unconscious conflict and the patient's recruitment of the analyst into the patient's internalized world.     

Prediction during statistical learning, and implications for the implicit/explicit divide

Accounts of statistical learning, both implicit and explicit, often invoke predictive processes as central to learning, yet practically all experiments employ non-predictive measures during training. We argue that the common theoretical assumption of anticipation and prediction needs clearer, more direct evidence for it during learning. We offer a novel experimental context to explore prediction, and report results from a simple sequential learning task designed to promote predictive behaviors in participants as they responded to a short sequence of simple stimulus events. Predictive tendencies in participants were measured using their computer mouse, the trajectories of which served as a means of tapping into predictive behavior while participants were exposed to very short and simple sequences of events. A total of 143 participants were randomly assigned to stimulus sequences along a continuum of regularity. Analysis of computer-mouse trajectories revealed that (a) participants almost always anticipate events in some manner, (b) participants exhibit two stable patterns of behavior, either reacting to vs. predicting future events, (c) the extent to which participants predict relates to performance on a recall test, and (d) explicit reports of perceiving patterns in the brief sequence correlates with extent of prediction. We end with a discussion of implicit and explicit statistical learning and of the role prediction may play in both kinds of learning.     

Dissociable neural systems of sequence learning

Although current theories all point to distinct neural systems for sequence learning, no consensus has been reached on which factors crucially define this distinction. Dissociable judgment-linked versus motor-linked and implicit versus explicit neural systems have been proposed. This paper reviews these two distinctions, yet concludes that these traditional dichotomies prove insufficient to account for all data on sequence learning and its neural organization. Instead, a broader theoretical framework is necessary providing a more continuous means of dissociating sequence learning systems. We argue that a more recent theory, dissociating multidimensional versus unidimensional neural systems, might provide such framework, and we discuss this theory in relation to more general principles of associative learning and recent imaging findings.     

Redundant sensory information does not enhance sequence learning in the serial reaction time task

In daily life we encounter multiple sources of sensory information at any given moment. Unknown is whether such sensory redundancy in some way affects implicit learning of a sequence of events. In the current paper we explored this issue in a serial reaction time task. Our results indicate that redundant sensory information does not enhance sequence learning when all sensory information is presented at the same location (responding to the position and/or color of the stimuli; Experiment 1), even when the distinct sensory sources provide more or less similar baseline response latencies (responding to the shape and/or color of the stimuli; Experiment 2). These findings support the claim that sequence learning does not (necessarily) benefit from sensory redundancy. Moreover, transfer was observed between various sets of stimuli, indicating that learning was predominantly response-based.     

Coping,psychological adjustment,and complementary and alternative medicine use in persons living with hiv and aids

Abstract

Many HIV-positive individuals dissatisfied with allopathic approaches to disease management have turned to complementary and alternative medicines (CAM). Although people use CAM for a variety of reasons (e.g., symptom management, holistic approach towards healthcare, improved immunity), the psychological benefits that these treatments may have are still not fully understood. The present study was designed to further previous research that demonstrated relationships between CAM use, stress appraisals, and coping behaviors. HIV-positive individuals (N= 127) completed measures assessing stress appraisals, coping, psychological adjustment, satisfaction with life, and immune functioning. After controlling for ethnicity and sexual orientation, stress appraisals and coping behaviors were found to be related to CAM use. Further, curvilinear relationships between CAM use and adjustment emerged, suggesting that some CAM use may be adaptive. Self-reported immune measures were unrelated to CAM use. In all, it appears that CAM use may be a complex form of coping that assists individuals in adjusting to a life-threatening illness. The implications of these findings with respect to adherence to highly active antiretroviral therapies (HAART) are also discussed.     

Discrete Process Model for Quantum Systems of Matter and Mind

Attempts to create a coherent scientific picture of the world as a whole on the basis of quantum physics has sped up at the turn of the millennium. There particularly seem to be expectations that the development of a new kind of quantum mechanics could make it possible to describe both matter and consciousness in one frame of reference (“dual aspect approach”). These ideas are often results of brilliant intuitive visions but as yet not able to produce testable hypotheses. Maybe “wave mechanics” is not very suitable in the study of consciousness from the quantum mechanical point of view. The aim of this article is to show how both the matter and the mind systems can be described with one coherent mathematical model if we assume both space and time to be discrete.     

A process study of long-term treatment: comparing a successful and a less successful outcome

This study examined therapist technique and patient change in emotional experiencing and defense mechanisms in the successful and unsuccessful long-term psychoanalytic treatments of two male patients. Two consecutive sessions every 6 months were analyzed for each patient. Therapist interventions, patient defense mechanisms, and patient emotional experiencing were assessed using the Psychodynamic Intervention Rating Scale, Defense Mechanism Rating Scale and the Experiencing Scale, respectively. Between and within-session analyses were conducted to determine the impact of the patient’s defensive functioning and experiencing on therapist interventions, and the effect of therapist interventions on those same two patient variables. Pearson’s Coefficient was utilized for between-session analysis; within-session analysis tracking moment-to-moment changes in patient and therapist functioning was performed using lag sequential analysis. Across therapy, therapist use of Interpretive Interventions was associated with increased emotional engagement and decreased defense maturity; the use of Supportive Interventions had the opposite effect. Within-session analysis revealed that use of Supportive Interventions when emotional engagement is low, followed by interpretative interventions, occurred in the successful case. Persistent use of Supportive Interventions in the context of low emotional engagement was observed in the unsuccessful case. This study suggests that failure to stimulate emotional engagement through interpretation can negatively affect therapeutic outcome.     

Gender of the expresser moderates the effect of emotional faces on the startle reflex

It has been suggested that the impact of emotional expressions on the startle reflex is influenced by the intention communicated by the expression (e.g., the intention to attack). However, we propose that the meaning of an emotional expression is not only based on the intention, but is also influenced by characteristics of the expresser such as gender: since men are typically seen as more dominant than women, anger expressed by men should be perceived as particularly threatening, thus amplifying the startle response. We compared the influence of anger, fear and neutral expressions shown by men and women on the startle reaction. Startle reactions were measured using electromyography. As predicted, we found stronger startle reactions after the presentation of anger expressed by men compared to fearful and neutral expressions shown by men. For female expressers, the startle response was not affected by expression type.
