Vultures as an overlooked model in cognitive ecology

Animal Cognition - Despite important recent advances in cognitive ecology, our current understanding of avian cognition still largely rests on research conducted on a few model taxa. Vultures are...     

Transitions to Adulthood Among First Generation Sub-Saharan African Immigrant Adolescents in Canada: Evidence from a Qualitative Study in Montreal

In industrialized societies, a large number of studies have addressed the various patterns of adolescent transitions to adulthood. While most studies on migration have examined aspects of migrants’ integration into host societies, few researches, however, have dealt with the intersection of these two topics—the experiences and problems encountered by immigrant adolescents. This research focuses on the transition to adulthood among sub-Saharan African youth who live in Montreal, Canada. This group is still poorly known in Canada, and the few studies that exist on sub-Saharan Africans in Canada showed that they are among the most discriminated groups socially and economically. Both immigrant youth and their parents/families’ experience a transition to adapt to a new place, and these respective experiences may affect their relationships. Our research objectives are to examine the conditions in which African immigrant adolescents experience their transition to adulthood and to assess whether the gaps between the two perspectives are purely generational or are partly specific to this group. The data are based on qualitative focus group discussions and individual interviews conducted in Montreal in 2005–2007 among first generation immigrants from sub-Saharan Africa and a control group of native Canadians (whose parents were also born in Canada), men and women between age 12 and 18 and young adults aged 18 to 29. Our results show that in all cases the question of becoming responsible, making one’s own decision is central. What varies is the process through which the young people become responsible.     

Some Observations on Group Therapy with the Blind

This study integrates the theoretical assumptions underlying member preparation for group into a series of pregroup interview guidelines, which are then field tested for reliability and validity using a Solomon Four-Group design. Findings indicate a significant relationship exists between those individuals having the pregroup interview and a realistic perception of group membership and understanding of group purpose. The third dimension, which tested congruence between member goals and group purpose due to having the pregroup interview, was not significant. Implications of the study and suggestions for further research are discussed.     

Assessment of the global intelligence and selective cognitive capacities in preterm 8-year-old children

The aim of this study was to assess various cognitive abilities such as attention, IQ, reasoning, and memory related to academic achievement in 8- and 9-year-old preterm children. A total of 141 children were assessed. The preterm group (=37 weeks) comprised 63 children and was compared to 78 full-term children. Attention was evaluated using the d2 Selective Attention test, and the IQ by the L-M form of the Stanford-Binet Intelligence Scale, establishing a profile of abilities: perception, memory, comprehension, reasoning, and verbal fluency. Significant differences in IQ were found between the preterm and full-term children. Of the cognitive abilities assessed, the only significant differences were found in verbal fluency, with preterm boys showing lower verbal fluency scores than full-term children. In conclusion, all preterm groups have attention ability similar to that of full-term children. However, preterm children obtain lower scores in intelligence measures. In addition, preterm boys have verbal fluency difficulties. Taking into account the increase in preterm births, suitable intervention programs must be planned to attend the difficulties found.     

The Witness to Witness Program: Helping the Helpers in the Context of the COVID-19 Pandemic

The Witness to Witness Program (W2W), based on Weingarten’s witnessing model (2000, 2003, 2004), began in July 2018 and originally was established to support healthcare workers and attorneys (our partners) who were experiencing empathic distress working with people involved in various stages of the detention process. The W2W program evolved to offer four primary components: clinician listening sessions geared to deep understanding of the person’s story of their work and its challenges; an inventory of the person’s current internal and external resources both in the present and in the past; help with removal of barriers to those resources; and development of a personal toolkit to handle stress. Additional services available to partners and their organizations included psycho-educational webinars, facilitated peer support groups, and organizational consultations to foster trauma-sensitive and resilience-hardy work environments. In March, after lockdowns due to the coronavirus pandemic, W2W pivoted to focus on handouts and webinars addressing how to cope with distress and moral injury, maintaining resilience, coping with grief, and dealing with multiple losses caused by the pandemic. Disaster sparked collaboration and innovation. A train the trainer model was developed to reach more community health workers providing services to the Latinx community dealing with losses similar to those experienced by the clients they serve. W2W continues to create virtual communities of support. In doing so we practice doing reasonable hope together (Weingarten, Family Process, 2010, 49, 5).     

Independence of first- and second-order memories in newborn rabbits

The mammary pheromone promotes the acquisition of novel odorants (CS1) in newborn rabbits. Here, experiments pinpoint that CS1 becomes able to support neonatal learning of other odorants (CS2). We therefore evaluated whether these first- and second-order memories remained dependent after reactivation. Amnesia induced after CS2 recall selectively blocked this memory, when recall and amnesia of CS1 left the souvenir of CS2 safe; this finding partially differed from results obtained in adult mammals. Thus, in this model of neonatal appetitive odor learning, second-order memory seems to depend on first-order memory for its formation but not for its maintenance.     

Visual context modulates potentiation of grasp types during semantic object categorization

Substantial evidence suggests that conceptual processing of manipulable objects is associated with potentiation of action. Such data have been viewed as evidence that objects are recognized via access to action features. Many objects, however, are associated with multiple actions. For example, a kitchen timer may be clenched with a power grip to move it but pinched with a precision grip to use it. The present study tested the hypothesis that action evocation during conceptual object processing is responsive to the visual scene in which objects are presented. Twenty-five healthy adults were asked to categorize object pictures presented in different naturalistic visual contexts that evoke either move- or use-related actions. Categorization judgments (natural vs. artifact) were performed by executing a move- or use-related action (clench vs. pinch) on a response device, and response times were assessed as a function of contextual congruence. Although the actions performed were irrelevant to the categorization judgment, responses were significantly faster when actions were compatible with the visual context. This compatibility effect was largely driven by faster pinch responses when objects were presented in use-compatible, as compared with move-compatible, contexts. The present study is the first to highlight the influence of visual scene on stimulus–response compatibility effects during semantic object processing. These data support the hypothesis that action evocation during conceptual object processing is biased toward context-relevant actions.     

An Essay In The Aid Of Writing History: Fictions Of Historiography

In what follows I explore the question of fictionality in history writing. First, I venture into the unfamiliar genre of ego-histoire and make my own professional training in the tenets of positivist or realist historiography an object of theoretical reflection and critical analysis. Then as a way of dealing with the literary dimension of written history, I make a canonical work in history of education an object of rhetorical analysis. Finally, as another way of coming to terms with the fictions of historiography, I revisit one of my own productions and make it an object of metacritical consideration. My central theme is that historiographical realism alone will not suffice , that historians are as dependant upon literary invention as upon documents, that history cannot be written without the aid of the fictions of historiography, and that the difference between the historian and the novelist is narrower than we may have been accustomed to think. I further argue that attention to the literary or rhetorical dimension of history is long overdue in history of education, where it flourishes unacknowledged. I conclude that historical writing is not just a literary pastime and the issue remains: how to come to grips with fictionalizing and the truth claims of historiography.     

An approach to the problem of meaning: Semantic networks

An approach to the problem of meaning through the postulation of semantic networks is presented. Subjects generated them for ten concrete and ten abstract nouns with two different procedures. Comparisons were made between the semantic network and the set of associations given to each concept. Finally, both the concrete concepts' and the abstract concepts' networks were compared. It was suggested that a form of meaning is given by the semantic network of the concept, by a reconstructive memory process.
