Patterns of semantic memory impairment in Mild Cognitive Impairment

Although the semantic memory impairment has been largely documented in Alzheimer's disease, little is known about semantic memory in the preclinical phase of the disease (Mild Cognitive Impairment). The purpose of this study was to document the nature of semantic breakdown using a battery of tests assessing different aspects of conceptual knowledge: knowledge about common objects, famous people and famous public events. Results indicate that all domains of semantic memory were impaired in MCI individuals but knowledge about famous people and famous events was affected to a greater extent than knowledge about objects. This pattern of results suggests that conceptual entities with distinctive and unique properties may be more prone to semantic breakdown in MCI. In summary, results of this study support the view that genuine semantic deficits are present in MCI. It could be useful to investigate the etiological outcome of patients failing or succeeding at such tests.     

Mind the gap: Increasing associations between the self and Blacks with approach behaviors

Although perceived differences between outgroup social categories and the self are often cited as a major contributor to prejudice and intergroup tension, surprisingly few studies have examined ways to improve associations between the self and racial outgroups. The present research investigated one strategy to increase these associations-approach training. Specifically, 3 studies investigated the impact of training participants to conceptually approach Blacks on 3 separate measures: 2 response latency measures indexing the strength of association between the self and Blacks and a psychophysiological measure indexing brain activity in response to Blacks in the context of the self. A fourth study examined the link between earlier research on the impact of approach training on implicit prejudice against Blacks and the current results related to self-Black associations. Together, these findings provided consistent evidence that training in approaching Blacks increases associations between the self and Blacks that in turn reduce implicit prejudice against Blacks.     

Multidimensional scaling of musical time estimations

The aim of this study was to identify the psycho-musical factors that govern time evaluation in Western music from baroque, classic, romantic, and modern repertoires. The excerpts were previously found to represent variability in musical properties and to induce four main categories of emotions. 48 participants (musicians and nonmusicians) freely listened to 16 musical excerpts (lasting 20 sec. each) and grouped those that seemed to have the same duration. Then, participants associated each group of excerpts to one of a set of sine wave tones varying in duration from 16 to 24 sec. Multidimensional scaling analysis generated a two-dimensional solution for these time judgments. Musical excerpts with high arousal produced an overestimation of time, and affective valence had little influence on time perception. The duration was also overestimated when tempo and loudness were higher, and to a lesser extent, timbre density. In contrast, musical tension had little influence.

A case of prosopagnosia with some preserved covert remembrance of familiar faces

This paper presents the detailed analysis of a case of prosopagnosia in a 54-year-old male farmer following bioccipital vascular disease. In-depth clinical investigations confirmed the diagnosis of prosopagnosia and revealed the absence of any associated defect, except for a slight aspecific disturbance of the short-term memory. Further study of this case indicated that the trouble was not concerned with the class of complex visual stimuli, was not even concerned with facial expressions or unknown faces, was not a perceptual defect, but was related mainly to the operation of individualization. The memory hypothesis was thus retained and supported. Moreover, exploration of the difficulty indicated that the deficiency was limited to defective access to conscious information concerning faces and information associated with these faces (name, context, etc.), effectively stored in memory.     

Moral Luck,Responsibility, and Systems of Tort Liability

Bernard Williams drew our attention to what might be wrong with denying the role of luck in our understanding of agency and responsibility. Susan Wolf and David Enoch, in separate works, have asked us to focus instead on what might be virtuous and valuable in embracing that role, and on how our institutions might assist us in that regard. They claim that the agent who ‘takes’ a responsibility that law or morality do not already assign to them may be displaying a special moral virtue or exercising a distinctive moral power. I raise some objections to Wolf’s and Enoch’s case for that claim, and query some of its purported institutional implications for tort law systems.

Personality,Childhood Experience,and Political Ideology

This article studies the relationship between the “big five” personality traits and political ideology in a large U.S. representative sample (N = 14,672). In line with research in political psychology, “openness to experience” is found to predict liberal ideology, and “conscientiousness” predicts conservative ideology. The availability of family clusters in the data is leveraged to show that these results are robust to a sibling fixed‐effects specification. The way that personality might interact with environmental influences in the development of ideology is also explored. A variety of childhood experiences are studied that may have a differential effect on political ideology based on a respondent's personality profile. Childhood trauma is found to interact with “openness” in predicting ideology, and this complex relationship is investigated using mediation analysis. These findings provide new evidence for the idea that differences in political ideology are deeply intertwined with variation in the nature and nurture of individual personalities.     

Interrogating the Epiphenomenalist Tradition

Epiphenomenalism has had a long historical tradition. It is the view that mental properties are causally inert with respect to the physical world. In this paper, I argue that this tradition faces enormous challenges and needs better arguments to defend its position, and to demonstrate this, I interrogate the (mostly contemporary) strands including computationalism, the idea of the illusion of conscious will, and causal exclusionism.
