Linking somatic and symbolic representation in semantic memory: the dynamic multilevel reactivation framework

Biological plausibility is an essential constraint for any viable model of semantic memory. Yet, we have only the most rudimentary understanding of how the human brain conducts abstract symbolic transformations that underlie word and object meaning. Neuroscience has evolved a sophisticated arsenal of techniques for elucidating the architecture of conceptual representation. Nevertheless, theoretical convergence remains elusive. Here we describe several contrastive approaches to the organization of semantic knowledge, and in turn we offer our own perspective on two recurring questions in semantic memory research: (1) to what extent are conceptual representations mediated by sensorimotor knowledge (i.e., to what degree is semantic memory embodied)? (2) How might an embodied semantic system represent abstract concepts such as modularity, symbol, or proposition? To address these questions, we review the merits of sensorimotor (i.e., embodied) and amodal (i.e., disembodied) semantic theories and address the neurobiological constraints underlying each. We conclude that the shortcomings of both perspectives in their extreme forms necessitate a hybrid middle ground. We accordingly propose the Dynamic Multilevel Reactivation Framework—an integrative model predicated upon flexible interplay between sensorimotor and amodal symbolic representations mediated by multiple cortical hubs. We discuss applications of the dynamic multilevel reactivation framework to abstract and concrete concept representation and describe how a multidimensional conceptual topography based on emotion, sensation, and magnitude can successfully frame a semantic space containing meanings for both abstract and concrete words. The consideration of ‘abstract conceptual features’ does not diminish the role of logical and/or executive processing in activating, manipulating and using information stored in conceptual representations. Rather, it proposes that the materials upon which these processes operate necessarily combine pure sensorimotor information and higher-order cognitive dimensions involved in symbolic representation.     

Precariousness and Quality of Life—a Qualitative Perspective on Quality of Life of Households in Precarious Prosperity in Switzerland and Spain

Households’ resources and constraints are key components of quality of life (QOL). QOL also depends on how these are evaluated. In times of crisis one expects subjective wellbeing and quality of life to decline. We argue that the quality of life depends on objective living conditions, their subjective evaluation and the ability to maintain or improve the situation of “embedded individuals”. This ability, in turn, depends on the opportunities provided by the state, labour markets, families and communities. We analyse qualitative interviews (2008–2010) with around 25 households in precarious prosperity in two cities (Pamplona, Spain and Lausanne, Switzerland) to elaborate their QOL. Few sampled Swiss households witnessed a decline in socio-economic status, contrary to the Spanish. Domains important to these households for QOL varied according to the opportunity structures: in the Spanish sample QOL was related to the opportunities for income, work, and security to plan ahead; in the Swiss sample to health, work-life balance and loneliness. In both samples, QOL varied according to scope of agency, people’s position within the life course, the households’ past experiences, current situation and future perspectives. Lack of future perspectives and opportunities lowered QOL; reframing, adaption and accepting the situation sometimes moderated QOL. We conclude that apart from living conditions and/or subjective wellbeing, households’ agency within opportunity structures is a promising direction for further research in QOL.     

Dissonance and abstraction: Cognitive conflict leads to higher level of construal

This study investigated the effects of cognitive conflict on abstract thinking. According to action‐identification theory, an ambiguous and unfamiliar situation might propel an individual to a more abstract mindset. Based on this premise, cognitive conflict was hypothesized to put people in an abstract mindset. The induced compliance paradigm, in which participants are asked to write a counter‐attitudinal essay under either low choice (producing little dissonance) or high choice (producing more dissonance), was employed. Results showed that an abstract mindset was in fact activated in the induced compliance paradigm, and this effect was more pronounced for participants having a more concrete mindset to begin with. The results suggest that the experience of cognitive conflict is closely related to increased abstraction.

HPV High Risk and Protective Behaviors: The Effects of Religious Affiliation

The majority of Americans identify themselves as belonging to some religious group. There is a mixed body of literature on whether or not religious affiliation has an influence on engaging in risky behaviors among young adults attending college. This study examined associations between religious affiliation, risky sexual practices, substance use, and family structure among a sample of predominantly white college females attending a southeastern university. Given the high risk of acquiring genital human papillomavirus infection as a result of high risk sexual practices, gaining a better understanding of how religious affiliation can be used to promote healthy sexual behaviors is warranted.     

Modulation of the conflict monitoring intensity: The role of aversive reinforcement,cognitive demand,and trait-BIS

According to Botvinick’s (2007) integrative account, conflict monitoring is aversive because individuals anticipate cognitive demand, whereas the revised reinforcement sensitivity theory (rRST) predicts that conflict processing is aversive because individuals anticipate aversive reinforcement of erroneous responses. Because these accounts give different reasons for the aversive aspects of conflict, we manipulated cognitive demand and the aversive reinforcement as a consequence of wrong choices in a go/no-go task. Thereby, we also aimed to investigate whether individual differences in conflict sensitivity (i.e., in trait anxiety, linked to high sensitivity of the behavioral inhibition system [trait-BIS]) represent the effects of aversive reinforcement and cognitive demand in conflict tasks. We expected that these manipulations would have effects on the frontal N2 component representing activity of the anterior cingulate cortex. Moreover, higher-trait-BIS individuals should be more sensitive than lower-trait-BIS individuals to aversive effects in conflict situations, resulting in a more negative frontal N2 for higher-trait-BIS individuals. In Study 1, with N = 104 students, and Study 2, with N = 47 students, aversive reinforcement was manipulated in three levels (within-subjects factor) and cognitive demand in two levels (between-subjects factor). The behavioral findings from the go/no-go task with noncounterbalanced reinforcement levels (Study 1) could be widely replicated in a task with counterbalanced reinforcement levels (Study 2). The frontal mean no-go N2 amplitude and the frontal no-go N2 dipole captured predicted reinforcement-related variations of conflict monitoring, indicating that the anticipation of aversive reinforcement induces variations in conflict monitoring intensity in frontal brain areas. The aversive nature of conflict was underlined by the more pronounced conflict monitoring in higher- than in lower-trait-BIS individuals.     

Interpretation and method

Abstract

Interpretation started as the central tool of psychoanalytic theory, but it has undergone changes, just as the theory it was based on has evolved. Not only have these significant changes been determined by cultural trends, but different authors have also contributed to their evolution through their approaches to various other pathologies besides neurosis. Today, the cure process is divided between those who believe that therapeutic efficiency should be based on the different interpretation models, and those who maintain that it can be only sustained by the modifying capacity of the therapeutic relationship. Both positions are supposedly upheld by the results of tests that both models believe are sufficient proof but that, in the current author's opinion, lead back to the type of pathology they arose from, although they may at times attempt to cover the entire theoretical spectrum. The position upheld by Gedo—who considers that the psychoanalyst's intervention will depend on the degree of evolution that the pathology has achieved—is of great interest for specific practice. Hence, the more primitive levels require a treatment founded on holding, whereas more evolved pathologies require a more classic level of interpretation. This implies that the stages of a particular patient's evolution may require interventions at different levels, even though these may be founded on different theoretical models. This model, which we may brand as eclectic, is basically the one we find underpinning different theoretical models, which effectively appear to integrate others.     

The uses of humor in life,neurosis and in psychotherapy: Part 2

Abstract

The first part of the paper focused on the dynamics of wit in life, literature, and psychoanalysis; the second part of this paper is devoted to the use of humor in therapy. The central concept is Freud's psychoanalytic method, as distinguished from Freud's various theories of disorder, or neurosis, with a further elaboration of Freud's inherently interpersonal conception of the analytic process, already present in the cathartic phase of the therapeutic technique. The cathartic, or discharge, function of humor is connected to reciprocal free association (a term coined by the author) to define the mutual and reciprocal free association in analysand and analyst, playing an essential role in the genesis of insight and interpretation. Humor has its role in loosening repression, facilitating the emergence of unconscious emotions and ideas, bringing to light character defenses, and thus driving the process of analysis.     

Different origins and meanings of acute acting-out in an inpatient psychotherapeutic setting

In this paper I describe four different sources of acute acting-out behaviour as may be observed in long-term hospitalised patients suffering from severe personality disorders. I hope to demonstrate that acute psychological distress does not happen in a vacuum, but that specific intrapsychic and interpersonal dynamics within the hospital setting are at the root of what appears overtly as nonspecific emotional and behavioural disturbance. I argue that the hospital team's correct insight into the factors underlying acute acting-out is crucial to the implementation of therapeutic interventions aimed to decrease the patient's disturbed state of mind.
