Regression I. Experimental approaches to regression

The concept of regression is considered with an emphasis on the differences between the positions of Freud and Jung regarding its significance. The paper discusses the results of experimental analyses of individual experience dynamics (from gene expression changes and impulse neuronal activity in animals to prosocial behaviour in healthy humans at different ages, and humans in chronic pain) in those situations where regression occurs: stress, disease, learning, highly emotional states and alcohol intoxication. Common mechanisms of regression in all these situations are proposed. The mechanisms of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the representation of low-differentiated (older) systems in the actualized experience. In all of the cases of dedifferentiation mentioned above, the complexity of the systemic organization of behaviour significantly decreases.     

Hemispheric asymmetries in meaning selection: Evidence from the disambiguation of homophonic vs. heterophonic homographs

Research investigating hemispheric asymmetries in meaning selection using homophonic homographs (e.g., bank), suggests that the left hemisphere (LH) quickly selects contextually relevant meanings, whereas the right hemisphere (RH) maintains a broader spectrum of meanings including those that are contextually irrelevant (e.g., Faust & Chiarello, 1998). The present study investigated cerebral asymmetries in maintaining the multiple meanings of two types of Hebrew homographs: homophonic homographs and heterophonic homographs (e.g., tear). Participants read homographs preceded by a biasing, or a non-biasing sentential context, and performed a lexical decision task on targets presented laterally, 1000 ms after the onset of the sentence-final ambiguous prime. Targets were related to either the dominant or the subordinate meaning of the preceding homograph, or unrelated to it. When targets were presented in the LVF/RH, dominant and subordinate meanings, of both types of homographs, were retained only when they were supported by context. In a non-biasing context, only dominant meanings of homophonic homographs were retained. Alternatively, when targets were presented in the RVF/LH, priming effects for homophonic homographs were only evident when meanings were supported by both context and frequency (i.e., when context favored the dominant meaning). In contrast, heterophonic homographs resulted in activation of dominant meanings, in all contexts, and activation of subordinate meanings, only in subordinate-biasing contexts. The results challenge the view that a broader spectrum of meanings is maintained in the right than in the left hemisphere and suggest that hemispheric differences in the time course of meaning selection (or decay) may be modulated by phonology.     

Integrating Content and Structure Aspects of the Self: Traits,Values, and Self‐Improvement

Research on the structure of the self has mostly developed separately from research on its content. Taking an integrative approach, we studied two structural aspects of the self associated with self‐improvement—self‐discrepancies and perceived mutability—by focusing on two content areas, traits and values. In Studies 1A–C, 337 students (61% female) reported self‐discrepancies in values and traits, with the finding that self‐discrepancies in values are smaller than in traits. In Study 2 (80 students, 41% female), we experimentally induced either high or low mutability and measured perceived mutability of traits and values. We found that values are perceived as less mutable than traits. In Study 3, 99 high school students (60% female) reported their values, traits, and the extent to which they wish to change them. We found that values predict the wish to change traits, whereas traits do not predict the wish to change values. In Study 4, 172 students (47.7% female) were assigned to one of four experimental conditions in which they received feedback denoting either uniqueness or similarity to others, on either their values or their traits. The results indicated that feedback that one's values (but not traits) are unique affected self‐esteem. Integrating between theories of content and structure of the self can contribute to the development of both.     

How to tell a wife from a hat: Affective feedback in perceptual categorization

How do people understand that their perception is correct? In line with the recurring idea of perception as prediction, the affective feedback account of hypotheses testing suggests that correct perceptual predictions are reinforced with positive affect. In four experiments, we tested whether correct categorization of a degraded image will lead to more positive liking ratings. The obtained findings supported the proposed approach: subjects liked the images they were able to perceive correctly more than others. Importantly, these findings were independent of the initial affective valence of stimuli. A further investigation demonstrated that this effect exists only when answers are at least moderately confident. The obtained findings add to the growing amount of literature on the role of affect in basic cognitive processing.     

Spatial location and emotion modulate voice perception

ABSTRACT

How do we perceive voices coming from different spatial locations, and how is this affected by emotion? The current study probed the interplay between space and emotion during voice perception. Thirty participants listened to nonverbal vocalizations coming from different locations around the head (left vs. right; front vs. back), and differing in valence (neutral, positive [amusement] or negative [anger]). They were instructed to identify the location of the vocalizations (Experiment 1) and to evaluate their emotional qualities (Experiment 2). Emotion-space interactions were observed, but only in Experiment 1: emotional vocalizations were better localised than neutral ones when they were presented from the back and the right side. In Experiment 2, emotion recognition accuracy was increased for positive vs. negative and neutral vocalizations, and perceived arousal was increased for emotional vs. neutral vocalizations, but this was independent of spatial location. These findings indicate that emotional salience affects how we perceive the spatial location of voices. They additionally suggest that the interaction between spatial (“where”) and emotional (“what”) properties of the voice differs as a function of task.     

Does “Arab Spring” Mean The Beginning Of World System Reconfiguration?

In a previous article, “The Coming Epoch of New Coalitions: Possible Scenarios of the Near Future” (Grinin and Korotayev 2011 Grinin, L. E. 2011. The coming epoch of new coalitions: Possible Scenarios of the Near Future. World Futures, 67(8): 531–563. [Taylor & Francis Online] , [Google Scholar]), it was preliminarily demonstrated that the turbulent events of late 2010 and 2011 in the Arab World may well be regarded as a start of the global reconfiguration. The subsequent events have confirmed this supposition. That is why in the present article we develop this important theme. The article offers a thorough analysis of the internal conditions of Arab countries on the eve of revolutionary events, as well as causes and consequences of the Arab Revolutions. The article also offers an analysis of similar historical World System reconfigurations starting with the sixteenth-century Reformation. The analysis is based on the theory (developed by the authors) of the periodical catch-ups experienced by the political component of the World System that tends to lag behind the World System economic component. Thus, we show that the asynchrony of development of various functional subsystems of the World System is a cause of the synchrony of major political changes. In other words, within the globalization process, political transformations tend to lag far behind economic transformations. And such lags cannot constantly increase, the gaps are eventually bridged, but in not quite a smooth way. The article also suggests an explanation why the current catch-up of the World System political component started in the Arab World.     

Acculturative hassles and immigrant adolescents: a life-domain assessment for Soviet Jewish refugees

In a sample of 146 adolescents, the authors developed and validated a measure of acculturative hassles for Soviet Jewish refugees. They based the measure on an ecological perspective, which focuses on hassles involving person-environment transactions occurring in life domains of school, family, peers, and language. The authors reviewed conceptual and methodological issues in existing instruments and incorporated efforts to address current limitations into instrument development. The measure was correlated with psychological distress, level of acculturation to Russian and U.S. cultures, and outcomes in life domains; it contributed to outcomes over and above effects of nonacculturative hassles. Implications for measurement of acculturative hassles are discussed.
