Different faces of (un)controllability: Control restoration modulates the efficiency of task switching

Uncontrollability has been often associated with impaired or rigid cognitive processing. However, perceived stability of uncontrollable events modulated some of these detrimental effects on cognition. We investigated whether the experience of sequential control loss and restoration can enhance cognitive flexibility. We manipulated uncontrollability using a concept formation procedure that entailed either only unsolvable tasks (control deprivation condition), unsolvable tasks followed by solvable ones (control restoration condition) or only solvable tasks (control condition). To assess cognitive flexibility, we used a task-switching procedure that incorporated social categories. In Experiment 1 participants categorized people based on gender or age, and in Experiment 2 and 3 based on gender or social roles. Participants showed more flexibility in control restoration than in control deprivation condition. Additionally, in Experiments 2 and 3 this effect was mainly pronounced in the condition where the task evoked more cognitive conflict. We discuss the motivational underpinnings of unstable experiences of control loss and restoration.

     

“Interest in the service of that which is disinterested.” Józef Tischner’s anthropologico-ethical project of work

This paper focuses on one of Tischner’s last and little-known essays on the issues concerning work in the era of free market and the hegemony of the laws of economic calculation. In a discussion with Dominique Méda and André Gorz, Tischner diagnoses various threats to contemporary forms of work. Tischner criticizes above all the one-sided—that is, only objective—conception of today’s work. Referring to his own and original anthropologico-ethical project of work, the Polish scholar draws the reader’s attention to the need to promote the subjective model of work to be construed as interhuman dialogue. In work, thus construed, Tischner discerns a guarantee of the moral order of contemporary societies. His anthropological-ethical concept of work successfully inscribes itself in some of the models of work of the future, which are very much promoted today.

     

A belief in trend reversal requires access to cognitive resources

There are two research traditions studying people's reactions to random binary events: one concerns serial choice reaction times, the other concerns predictions of events in a series. The present studies focused on comparing expectations between these two approaches. We formed and tested a general hypothesis that, regardless of the type of task, when an individual faces a sequence of events they initially expect trend continuation. Only when people assume that a sequence is random might they override the default and expect trend reversal instead. In a series of experiments we found that limitation of access to cognitive resources enhances expectations of trend continuation. Our interpretation of this finding is that an expectation of trend continuation is the default for the human cognitive system and that a belief in trend reversal requires access to cognitive resources to overcome the tendency to expect trend continuation.     

Slot Mereology Revised

The paper suggests two revisions of K. Bennett's system of slot mereology. The revisions do not touch on the philosophical rationale for this system, but are focused on certain logical deficiencies in her formalisation.     

Emotional Distress Associated with Surgical Treatment and its Relationship with Coping Profiles Among Chronically ill Older Patients

The study determines the patterns of coping styles among older patients with hip osteoarthritis and assesses the derived profiles in terms of perceived stress and anxiety before and after arthroplasty. Sixty-one hospital patients (mean age 70.3 years) were analysed one day before arthroplasty and three months after. The participants were assessed with the Brief-COPE (coping style), PSS-10 (perceived stress) and STAI (anxiety) psychometric tests. Four coping patterns were yielded using data clustering: rational, enterprising (resourceful), potentially maladaptive and flexible. Repeated measures ANOVA indicated a main effect within subjects but did not indicate that decreases of stress and anxiety varied differently between groups. Cluster 1 (a coping profile characterised by high helplessness, low active coping, high avoidance) reported significantly greater stress and anxiety than all other groups before and after hip replacement, while clusters 2 (flexible), 3 (resourceful) and 4 (rational) were characterised by similar levels of anxiety and stress. Older patients with osteoarthritis might differ in terms of emotional response to surgical treatment. Screening for coping styles at admission to hospital may indicate more vulnerable individuals.     

Lifestyle traits as predictors of driving behaviour in urban areas of Greece

The aim of this study was to examine possible links between different lifestyle patterns and aberrant driver’s behaviour. Personal interviews were conducted in a representative sample of 324 adults (18–65), all residents of Crete. Aberrant driver’s behaviour was assessed by the ‘driver behaviour questionnaire’ (DBQ). Also to measure different dimensions of lifestyle, first, a 26-items questionnaire was used, and second, three questions measuring ‘driving without destination’, related in previous findings with road accident risk. Four lifestyle patterns: ‘religion/tradition’, ‘driving aimlessly’, ‘sports’ and ‘culture’ are significant predictors of ordinary violations. ‘Driving without destination’ has a significant effect all three DBQ factors (b positive). ‘Religion/tradition’ was related only to ordinary violations (b negative) and ‘sports’ has a positive impact on ordinary violations and a negative impact on ‘errors’. Two lifestyle factors are related to more dangerous driving: ‘Driving without destination’ and/or pursuing a more ‘athletic way of living’. Road safety campaigns must teach the first group to use other hobbies and activities to vent their feelings and the second, not to overestimate their abilities, while driving.     

Directed forgetting of autobiographical memory in mild Alzheimer's disease

Using the autobiographical directed forgetting method (Barnier et al., 2007), the present paper addressed the intentional inhibitory processes of episodic and semantic autobiographical memory in Alzheimer's disease (AD). Mild AD patients and healthy elderly people were instructed to either forget or to continue remembering previously generated autobiographical events. In a later recall test they were asked to reconstruct the early-generated memories regardless of the forget/remember instruction. Autobiographical reconstruction was further distributed into episodic and semantic memories. Results showed no forget instruction effect on episodic or semantic autobiographical recall with AD patients, whereas healthy elderly people were able to inhibit only episodic autobiographical memories. The findings suggest an impairment of the intentional inhibitory processes in autobiographical memory with AD and a relative preservation of these mechanisms with normal ageing. They also demonstrate an earlier decline in the intentional inhibitory processes compared to the autobiographical deterioration in AD.     

Does identification predict community involvement? Exploring consequences of social identification among the Jewish minority in Poland

Previous research indicated that people who strongly identify with their own group are more involved in the group's actions. The current study examines the relation between three dimensions of group identification (affect, ties, centrality) and forms of community involvement among members of the Jewish minority in Poland. The strength of ingroup ties predicted involvement in the ethnic minority community. The link between identification and involvement was mediated by the cultural dominance. The reported study was the first quantitative survey of the Jewish community in post‐War Poland. Copyright © 2009 John Wiley & Sons, Ltd.
