Epistemic akrasia and the fallibility of critical reasoning

There is widespread disagreement about whether epistemic akrasia is possible. This paper argues that the possibility of epistemic akrasia follows from a traditional rationalist conception of epistemic critical reasoning, together with considerations about the fallibility of our capacities for reasoning. In addition to defending the view that epistemic akrasia is possible, we aim to shed light on why it is possible. By focusing on critical epistemic reasoning, we show how traditional rationalist assumptions about our core cognitive capacities help to explain the possibility of epistemic akrasia.     

When deserving translates into causing: The effect of cognitive load on immanent justice reasoning

In immanent justice reasoning, negative events are attributed to some prior moral failing, even in the absence of a physically plausible causal link between them. Drawing on just-world theory, we examined immanent justice reasoning as an intuitive, deservingness-guided form of causal judgment. Participants were exposed to a story about a man who either did or did not cheat on his wife and who was subsequently injured in a car accident. Under either high or low cognitive load, participants rated the extent to which they believed the accident was the result of the man's prior moral failings. The results showed that participants causally attributed the man's accident to his prior conduct when he was immoral (vs. not immoral) more strongly under high cognitive load. Further, moderated mediation analyses showed that perceived deservingness of the accident mediated the effect of the man's prior immoral behavior on immanent justice attributions more strongly under high cognitive load. These results offer support for the notion that immanent justice attributions reflect an automatic tendency to assume that people get what they deserve.     

Recognition memory for pictorial material in subclinical depression

Depression has been associated with impaired recollection of episodic details in tests of recognition memory that use verbal material. In two experiments, the remember/know procedure was employed to investigate the effects of dysphoric mood on recognition memory for pictorial materials that may not be subject to the same processing limitations found for verbal materials in depression. In Experiment 1, where the recognition test took place two weeks after encoding, subclinically depressed participants reported fewer know judgements which were likely to be at least partly due to a remember-to-know shift. Although pictures were accompanied by negative or neutral captions at encoding, no effect of captions on recognition memory was observed. In Experiment 2, where the recognition test occurred soon after viewing the pictures, subclinically depressed participants reported fewer remember judgements. All participants reported more remember judgements for pictures of emotionally negative content than pictures of neutral content. Together, these findings demonstrate that recognition memory for pictorial stimuli is compromised in dysphoric individuals in a way that is consistent with a recollection deficit for episodic detail and also reminiscent of that previously reported for verbal materials. These findings contribute to our developing understanding of how mood and memory interact.     

Reasoning about XML with temporal logics and automata

We show that problems arising in static analysis of XML specifications and transformations can be dealt with using techniques similar to those developed for static analysis of programs. Many properties of interest in the XML context are related to navigation, and can be formulated in temporal logics for trees. We choose a logic that admits a simple single-exponential translation into unranked tree automata, in the spirit of the classical LTL-to-Büchi automata translation. Automata arising from this translation have a number of additional properties; in particular, they are convenient for reasoning about unary node-selecting queries, which are important in the XML context. We give two applications of such reasoning: one deals with a classical XML problem of reasoning about navigation in the presence of schemas, and the other relates to verifying security properties of XML views.     

Caregiver burden and family functioning in different neurological diseases

Aim of this study is to examine caregiver burden and family functioning in different neurological conditions. Forty-two primary caregivers of patients with Amyotrophic Lateral Sclerosis (ALS), Alzheimer’s Disease and other dementia (AD), Parkinson’s Disease (PD), Acquired Brain Injuries (ABI) and Multiple Sclerosis (MS) were administered scales for the evaluation of caregiver burden (CBI) and family functioning (FACES IV). Caregiver burden was overall high, with caregivers of patients with ALS and ABI having exceeded the CBI cut-off score for possible burn-out. The average scores of caregivers of patients with AD or other dementia and PD were close to the cut-off score, whereas those of caregivers of patients with MS were significantly lower than the others. Family cohesion, family satisfaction and the quality of family communication were associated with reduced levels of caregiver burden, whereas disengagement was associated with a higher burden. The data from the present study confirm that caregiver burden is a relevant issue in the context of neurological diseases, especially for those causing higher degrees of impairment. Significant correlations with family functioning emerged as well, highlighting the importance of studying and treating caregiver burden within the context of family relations.     

Personal trust extends cooperation beyond trustees: A Mexican study

We studied 2 groups of workers from Oaxaca (Mexico) with different levels of income and education to investigate the role that the affective‐based psychological mechanism of personal trust, as evolutionarily acquired, plays on group cooperation. We measured trust levels through some questionnaires and cooperative behaviour through an iterated prisoner's dilemma under different conditions and analysed trust networks of group members. While these groups did not differ in trust levels or cooperation among trustees, they did differ in terms of cooperation with other group members. Such differences are related to dissimilarities in the trust network topology—as a measure of group cohesion. These results suggest that some personal trust networks extend cooperation within a group beyond trustees in a way that complements the role of the reputation for indirect reciprocity.     

Evaluation of Symptoms and Alexithymia in Psychiatric Patients: A Naturalistic Longitudinal Study in a Day Hospital

This study aimed to examine the effectiveness of a time-limited (10 months), combined individual and group treatment in a Day Hospital (DH) setting. Participants (N = 73) completed measures of general symptoms and alexithymia. We hypothesized improvements in these symptoms at the end of the overall therapeutic treatment. Results showed significant improvement in ability to identify and describe emotions and feelings, and in general symptoms. Differences in age and personality disorders were found at the end of the treatment: younger patients had less difficulty in identifying emotions, and psychotic patients have higher difficulty to describe feelings compared to patients with personality disorders. Furthermore, patients with schizophrenia had lower pathological symptoms compared to patients with mood disorders. This naturalistic longitudinal study demonstrates that DH treatments in group setting increase the patient‘s ability to symbolize and to connect their symptoms to thought and emotions.     

The effect of reinforcement probability on time discrimination in the midsession reversal task

We examined how biasing time perception affects choice in a midsession reversal task. Given a simultaneous discrimination between stimuli S1 and S2, with choices of S1 reinforced during the first, but not the second half of the trials, and choices of S2 reinforced during the second, but not the first half of the trials, pigeons show anticipation errors (premature choices of S2) and perseveration errors (belated choices of S1). This suggests that choice depends on timing processes, on predicting when the contingency reverses based on session duration. We exposed 7 pigeons to a midsession reversal task and manipulated the reinforcement rate on each half of the session. Compared to equal reinforcement rates on both halves of the session, when the reinforcement rate on the first half was lower than on the second half, performance showed more anticipation and less perseveration errors, and when the reinforcement rate on the first half was higher than on the second half, performance showed a remarkable reduction of both types of errors. These results suggest that choice depends on both time into the session and the outcome of previous trials. They also challenge current models of timing to integrate local effects.     

Relationship Between Posturography,Clinical Balance and Executive Function in Parkinson´s Disease

This study aimed to evaluate the relationship between posturography, clinical balance, and executive function tests in Parkinson´s disease (PD). Seventy-one people participated in the study. Static posturography evaluated the center of pressure fluctuations in quiet standing and dynamic posturography assessed sit-to-stand, tandem walk, and step over an obstacle. Functional balance was evaluated by Berg Balance Scale, MiniBESTest, and Timed Up and Go test. Executive function was assessed by Trail Making Test (TMT) and semantic verbal fluency test. Step over obstacle measures (percentage of body weight transfer and movement time) were moderately correlated to Timed Up and Go, part B of TMT and semantic verbal fluency (r > 0.40; p < 0.05 in all relationships). Stepping over an obstacle assesses the responses to internal perturbations. Participants with shorter movement times and higher percentage of body weight transfer (higher lift up index) on this task were also faster in Timed Up and Go, part B of TMT, and semantic verbal fluency. All these tasks require executive function (problem solving, sequencing, shifting attention), which is affected by PD and contribute to postural assessment.
