Updating and inhibition processes in working memory: a comparison between Alzheimer's type dementia and frontal lobe focal damage

A large debate has recently focused on the componential nature of the working-memory system (), as evidenced by functional-imaging studies and by using more sophisticated experimental paradigms. The present work aims at further disentangling the role and effects of central executive (CE) and of phonological loop (PL). It is suggested that maintaining active verbal information mostly relates to an intact PL, while the inhibition of interfering information preponderantly involves the CE. To distinguish these effects, two groups of brain damaged patients were administered with an updating task. Frontal lobe patients showed major difficulties in inhibiting interfering information, an ability requiring an involvement of the CE component. In contrast, Alzheimer's dementia patients evidenced a relative impairment in maintaining relevant information, requiring the intervention of the PL.     

Noun verb dissociation in Parkinson's disease

A noun/verb dissociation with a relative verb deficit was found in patients affected by Parkinson's disease, even in relatively early stages, when mental deterioration is not severe. This finding is compatible with earlier observations, according to which verbs are dealt with in more anterior regions with respect to nouns. It also supports the speculation that the co-ordination and the manipulation of information associated with a verb world rely on the frontostriatal system.     

Locomotion and the preference for multi-tasking: Implications for well-being

The notion that locomotion concerns with moving from state to state (Higgins et al., Advances in experimental social psychology, Academic Press, New York, NY, 2003; Kruglanski et al., J Pers Soc Psychol 79:793–815, 2000) will instill a positive disposition toward multi-tasking was explored in three studies. Study 1 demonstrated the existence of the hypothesized link between locomotion and multi-tasking in a sample of university students. Study 2 showed that a person-situation fit in organizations based on this preference affects employees’ sense of well being. Finally, Study 3 conceptually replicated the results of Study 2 and demonstrated that the fit effects on well-being from the relation between locomotion and multi-tasking hold when both these variables are manipulated experimentally. These results support the basic idea that individuals with strong locomotion concerns benefit from activities more when they are performed simultaneously rather than sequentially.     

Psychobiology of Conflict

Human aggression and war are mediated by culture and social evolution. Human beings have a wide range of possible behaviors and possible cultural responses to aggression and the possibility of fear. This article analyzes the psychobiological dimensions of aggression and war, and proposes a way of approaching the complex interrelationship between biology, psychology, and culture.     

Love and death in the transference: The case of the Hungarian poet Attila József

SUMMARY

This paper gives an account of working as psychoanalytic psychotherapist in a GPs' surgery from a base within a local Psychotherapy Department. Particular attention is paid to how the GPs regard the therapist's work, as evidenced by their referrals and other contact with the therapist. An evolving relationship between the therapist and the GPs is described, and material from clinical work and meetings with the GPs is used to illustrate this. The idea of ‘Practice as patient’ is introduced as a model whereby the therapist considers how most usefully to engage with the GPs, and how this can enhance the understanding of the clinical task.     

Undecidable Decisions: Rationality Limits and Decision-making Heuristics

In this article the theoretic evolution and the empirical-experimental efforts that have led to the affirmation of the bounded/procedural rationality paradigm are discussed. Moreover, the debate on supporters of the “optimization” approach and supporters of the “bounded/procedural rationality” approach is traced, highlighting the irreconcilability of these two approaches and, in retort, a solid defense against a merely “reductionist” attempt of the innovative context of the Simonian theory. Critically going over the debate on decision dynamics, it becomes clear how, due to the uncertain nature of rational processes, it is impossible to establish the decision-making best way. The imperfect character of individual choice is explained by how the decider identifies a solution that appears satisfying in that moment due to cognitive and temporal limits.     

The effects of counterfactual defences on social judgements

Research on counterfactuals (‘If only…’) has seldom considered the effects of counterfactual communication, especially in a defensive context. In three studies, we investigated the effects of counterfactual defences employed by politicians. We assumed that self‐focused upward counterfactuals (‘If only I…, the outcome would have been better’) are a form of concession, other‐focused upward counterfactuals (‘If only they…, the outcome would have been better’) are a form of excuse, and self‐focused downward counterfactuals (‘If only I…, the outcome would have been worse’) are a form of justification. In Study 1, a counterfactual defence led to a more positive evaluation of the politician than a corresponding factual defence. Of the two types of defence, the counterfactual defence reduced the extent to which the politician was held responsible for the past event and was perceived as more convincing. In Study 2, counterfactual excuse and counterfactual justification were equally effective and led to a more positive evaluation of the politician than counterfactual concession. In Study 3, the higher effectiveness of counterfactual justification was independent from perceived ideological similarity with the politician, supporting the strength of this defence. These results show that counterfactual defences provide subtle communication strategies that effectively influence social judgements. Copyright © 2013 John Wiley & Sons, Ltd.     

Duration and numerical estimation in right brain‐damaged patients with and without neglect: Lack of support for a mental time line

Previous studies have shown that left neglect patients are impaired when they have to orient their attention leftward relative to a standard in numerical comparison tasks. This finding has been accounted for by the idea that numerical magnitudes are represented along a spatial continuum oriented from left to right with small magnitudes on the left and large magnitudes on the right. Similarly, it has been proposed that duration could be represented along a mental time line that shares the properties of the number continuum. By comparing directly duration and numerosity processing, this study investigates whether or not the performance of neglect patients supports the hypothesis of a mental time line. Twenty‐two right brain‐damaged patients (11 with and 11 without left neglect), as well as 11 age‐matched healthy controls, had to judge whether a single dot presented visually lasted shorter or longer than 500 ms and whether a sequence of flashed dots was smaller or larger than 5. Digit spans were also assessed to measure verbal working memory capacities. In duration comparison, no spatial‐duration bias was found in neglect patients. Moreover, a significant correlation between verbal working memory and duration performance was observed in right brain‐damaged patients, irrespective of the presence or absence of neglect. In numerical comparison, only neglect patients showed an enhanced distance effect for numerical magnitude smaller than the standard. These results do not support the hypothesis of the existence of a mental continuum oriented from left to right for duration. We discuss an alternative account to explain the duration impairment observed in right brain‐damaged patients.     

Prioritizing association strength versus value: the influence of self-regulatory modes on means evaluation in single goal and multigoal contexts

Means of goal attainment are said to be multifinal when they are capable of attaining more than 1 goal at the same time. Such means have an advantage over unifinal means because they have the potential to attain greater overall value. However, they have the disadvantage (relative to unifinal means) of diluting the association between the means and each of the goals (Zhang, Fishbach, & Kruglanski, 2007). In turn,diluted association strength is often interpreted as reduced means’ instrumentality. Given these tradeoffs between value (favoring a multifinal option) and instrumentality (favoring the unifinal option), the question is under what conditions 1 or the other would be selected. Based on regulatory mode theory(Higgins, Kruglanski, & Pierro, 2003; Kruglanski et al., 2000), we predicted and found in 5 experiments that individuals operating in a locomotion self-regulatory mode prefer a unifinal to multifinal means,whereas individuals operating in an assessment mode prefer multifinal to unifinal means. Implications of these findings for self-regulatory phenomena are discussed.     

Care vs Food as an Emotional Regulation Strategy in Elementary School Children: The Role of the Attachment Style

Abstract

According to attachment theory, potentially threatening stimuli tend to activate the attachment system for the search of the protective figure. In secure attachments, the experience of responsive relationships increases the probability of resorting to available figures as a strategy for regulating emotions in stressful situations. The aim of the research was to verify whether, in conditions of mild threat, children’s attachment styles affect the choice between caring relationships and food as a form of emotion regulation. We used a mixed experimental design to perform this research. Here, we presented children (N?=?65; M_age= 9.4) with threatening and neutral images and, afterwards, asked them to select from images of caring relationship or images of food. The results indicate that securely and ambivalently attached but not avoidantly attached children under both the neutral and threatening image conditions chose the care pictures over the food pictures. Second, only the securely attached increased their choice of care over food images in the threatening condition, and third, this difference was significant when compared with the avoidant children. In conclusion, the results show that although in general the choice of care is primary with respect to food, children with insecure attachments differ from secure children between the two options of emotional regulation.
