The Place of Philosophy in Africa

Recently there has been a strong movement towards reflections about the “geography of reason,” especially among philosophers who deal with postcolonial thinking. There is also a renewed interest among different schools of thought, both analytical and continental, in the ways our “life world,” or “embodiment,” or “situated cognition,” shape our minds and eventually the philosophy we do. As a result, we have seen some recent publications on the nature and import of the concept of “place” by authors such as Edward Casey, Jeff Malpas, and Bruce Janz. In Philosophy in an African place, Bruce Janz introduces the concept of “philosophy‐in‐place” with the question as to what it is to do philosophy in a particular context of lived experience or, more specifically, what it is to do philosophy in an African place. This paper expands on Janz's “philosophy‐in‐place” by developing what will be called a “philosophy through place.” It starts with Janz's discussion of the problem of placing philosophy and a philosophy‐in‐place. Then it attempts to develop an argument for a “philosophy through place” and its implications for considering the place of philosophy in Africa and the challenge it poses to philosophy.     

The Virtues of Ingenuity: Reasoning and Arguing without Bias

This paper describes and defends the “virtues of ingenuity”: detachment, lucidity, thoroughness. Philosophers traditionally praise these virtues for their role in the practice of using reasoning to solve problems and gather information. Yet, reasoning has other, no less important uses. Conviction is one of them. A recent revival of rhetoric and argumentative approaches to reasoning (in psychology, philosophy and science studies) has highlighted the virtues of persuasiveness and cast a new light on some of its apparent vices—bad faith, deluded confidence, confirmation and myside biases. Those traits, it is often argued, will no longer look so detrimental once we grasp their proper function: arguing in order to persuade, rather than thinking in order to solve problems. Some of these biases may even have a positive impact on intellectual life. Seen in this light, the virtues of ingenuity may well seem redundant. Defending them, I argue that the vices of conviction are not innocuous. If generalized, they would destabilize argumentative practices. Argumentation is a common good that is threatened when every arguer pursues conviction at the expense of ingenuity. Bad faith, myside biases and delusions of all sorts are neither called for nor explained by argumentative practices. To avoid a collapse of argumentation, mere civil virtues (respect, humility or honesty) do not suffice: we need virtues that specifically attach to the practice of making conscious inferences.     

TDQ-60 – a color picture-naming test for adults and elderly people: validation and normalization data

Word-finding difficulties are usually assessed with picture-naming tests. In this article, we present the TDQ-60, a new test designed to assess acquired lexical access deficits, taking into account semantics and psycholinguistic variables. The article includes three studies. Study 1 describes the development phase of the TDQ-60. In study 2, healthy control participants and individuals with a diagnosis of the semantic variant of primary progressive aphasia were assessed to establish the convergent and discriminant validity of the TDQ-60. Finally, in Study 3, a group of 305 young and elderly French-speaking adults from Quebec were assessed in order to provide normative data. The results demonstrate that the TDQ-60 has good convergent validity and good discriminant validity. This study also provides normative data in which were considered the effect of age and education.The TDQ-60 is a new valid picture-naming test, controlled for psycholinguistic variables and designed to identify the influence of semantics on lexical access in spoken production.     

Callous-Unemotional Traits Only Versus the Multidimensional Psychopathy Construct as Predictors of Various Antisocial Outcomes During Early Adolescence

The aim of this study was to compare callous-unemotional (CU) traits versus the multidimensional psychopathy construct in their ability to predict future and stable antisocial behavior. At baseline, a community sample of 996 Cypriot 12-year old adolescents (52% girls) completed measures that tap conduct problems (CP) and psychopathic traits, including CU. CP, aggression, and substance use were self-reported at 1–3 year follow-ups. Youths were assigned to six mutually exclusive groups based on their baseline levels of CP and psychopathic traits. Youth with CP scoring high on all three psychopathic traits dimensions (Psychopathic Personality?+?CP) showed the most robust and highest risk for future and stable CP, aggression, and substance use, followed by youth who were high on all three psychopathic traits dimensions but displayed no concurrent CP (Psychopathic Personality Only) and CP youth with low levels of psychopathic traits (CP Only). Youth with CP who merely manifested callous-unemotional traits (Callous-Unemotional?+?CP) were only at risk for future CP. The findings suggest that the CU traits-based approach for subtyping children with CP is less informative compared to a subtyping approach using various psychopathic traits dimensions in predicting future and stable forms of various antisocial outcomes. These findings and their consistency with prior work indicate the need for additional research to examine the various psychopathic traits dimensions rather than focusing solely on CU traits, especially for CP subtyping purposes.     

Psychopathic Traits in Adolescence: the Importance of Examining Components in Face Processing,Voice Processing,and Emotional Skill

This study examined relations among interpersonal, affective, and impulsive-irresponsible psychopathic traits, emotional capacities, and recidivism rates in 144 detained adolescents. Emotional skill was conceptualized using a range of constructs, including face and voice processing, emotional intelligence, and self-reported cognitive and affective empathy. In addition, the relation between these concepts and recidivism three years after the initial assessment was examined. Results indicated that interpersonal traits were positively associated with better facial identification of fearful faces, whereas affective traits were associated with worse facial identification of sad and happy faces as well as angry voices. Impulsive-irresponsible traits were associated with reduced emotional intelligence. Differential predictive utility of the three psychopathic traits dimensions was also evidenced. Findings highlight the need to consider the broad concept of psychopathy, but also its underlying dimensions.     

The influences of tropical climate on imagined walking time

This study investigated the effects of a Tropical Climate (TC) on actual and imagined walking times. Participants had to execute and imagine walking 3 distances with or without a 10-kg weight in either a TC or an Air Conditioning (AC) condition. The motor imagery quality was evaluated by computing the isochrony index. The results revealed that movement times were shorter for imagined walking than for actual walking and increased with the distance of the paths in both cases. By contrast, the effect of the load increased actual walking times for the 10- and 15-meter distances without affecting imagined walking times. Importantly, the isochrony index was negatively affected by the increase in load and distance and the effects of distance were amplified in a TC. These findings showed that the environmental climate in which motor imagery arises can modulate the subject’s ability to build up the temporal characteristics of simulated actions.     

Applying the SIDE model to brainwriting: The impact of intergroup comparison and anonymity on creative performance

According to the Social Identity model of Deindividuation Effects, intergroup comparison under anonymity accentuates social identity salience, potentially increasing motivation to work for one's group. The present experiment aimed to examine whether intergroup comparison and anonymity could boost creative performance in a brainwriting task. Sixty participants, randomly assigned to groups, wrote their ideas on sticky notes of the same (anonymity) or different color (individuation). To reinforce social identity salience, half the groups were told that their performance would be compared with other groups. As predicted, anonymity and intergroup comparison boosted both the number of nonredundant ideas produced by group members (fluency), and diversity of ideas pertaining to different categories (flexibility). By contrast, when social identity was not salient, anonymity led to an increase in the originality of ideas.     

When memory shifts toward more typical category exemplars: accentuation effects in the recollection of ethnically ambiguous faces

In 4 studies, the authors examined the impact of categorization on the recollection of ethnically ambiguous faces. Participants were presented with faces lying at various locations on mixed-race continua (i.e., Caucasian-North African and Caucasian-Asian faces were used as source images in a morphing program). In all studies, the prevalence of exclusive ethnic features in a face distorted participants' recollections of the face toward faces more typical of the category. Specifically, the recollection of 30% North African (or 30% Asian) faces shifted toward Caucasian source faces, whereas the recollection of 70% North African (or 70% Asian) faces shifted toward North African (Asian) source faces. Memory distortions did not emerge for extremely ambiguous (50%) faces and proved larger on mixed-race than same-race continua (Studies 3 and 4). Memory distortions also emerged with high levels of confidence. The authors elaborate on the theoretical and practical implications of these findings.     

Social sharing of emotion following exposure to a negatively valenced situation

Three experimental studies are reported in which we tested the prediction that negative emotion elicits the social sharing of the emotional experience. In two experiments, participants arrived at the laboratory with a friend and then viewed one of three film excerpts (nonemotional, moderate emotion, or intense emotion) alone. Afterwards, the participants who saw the film had an opportunity to interact with the friend and their conversation was recorded. In both experiments participants who had seen the intense emotion excerpt engaged in significantly more social sharing than did participants in the other two conditions. A third experiment extended the investigation to social sharing in everyday life and replicated the previous results. Nonemotional explanations of the effects observed were also ruled out. Results are discussed in the context of the relation between emotional intensity and amount of social sharing.
