Identity matching and oddity learning in patients with moderate to severe Alzheimer-type dementia

Discrimination learning was investigated in patients with moderate to severe Alzheimer-type dementia (AD), comparing their performance with age-matched controls. Four AD patients were trained to criterion on identity matching and then shifted to the same task with novel stimuli. The AD patients showed no savings in learning to match novel stimuli, whereas a comparative group of four control subjects rapidly learned the novel matching discrimination, maintaining criterion performance on the transfer test. A second group of four patients was initially trained on oddity, taking a similar number of trials to reach criterion as the matching group. When these patients were subsequently shifted to the matching task with novel stimuli, they performed substantially worse than the first group of patients who had learned the matching task in the first stage. The lack of positive transfer in the shift between matching to matching suggests that the AD patients solved the identity-matching task on the basis of stimulus-response associations rather than a rule. The presence of negative transfer after shifting from oddity to matching may be explained by a pre-disposition to respond to a novel stimulus that is carried over into the matching task, but this warrants further investigation, as indicated in the discussion.     

Un-thought out metaphysics in analytical psychology: a critique of Jung's epistemological basis for psychic reality

The author investigates the relation of Kant, Schopenhauer and Heidegger to Jung's attempts to formulate theory regarding the epistemological conundrum of what can and what cannot be known and what must remain uncertain. Jung's ambivalent use and misuse of Kant's division of the world into phenomenal and noumenal realms is highlighted in discussion of concepts such as the psychoid archetype which he called 'esse in anima' and his use of Schopenhauer's concept of 'will' to justify a transcendence of the psyche/soma divide in a postulation of a 'psychoid' realm. Finally, the author describes Jung's reaction to Heidegger's theories via his assertion that Heidegger's 'pre-given world design' was an alternate formulation of his concept of the archetypes. An underlying theme of the paper is a critique of Jung's foundationalism which perpetuates the myth of an isolated mind. This model of understanding subjectivity is briefly contrasted with Heidegger's 'fundamental ontology' which focuses on a non-Cartesian 'understanding' of the 'presencing of being' in everyday social and historical contexts.     

The Structure of Creativity in Primary Education: An Empirical Confirmation of the Amusement Park Theory

In this study, we explored the structure of pupils’ creativity in primary education following the Amusement Park Theory, by investigating undiscovered linkages between the domains of writing, mathematics, and drawing. More specifically, we examined: (a) whether some domains and general thematic areas are more closely related to each other than to others, (b) whether literacy and mathematical ability are specific underlying traits of creativity in writing and mathematics, respectively, and (c) whether intelligence and divergent thinking are related to creativity in all domains. The sample consisted of 331 Dutch 4th grade pupils. For each research question, a model was analyzed using structural equation modeling. We found creativity in mathematics and creativity in writing to be most similar, followed by creativity in mathematics and creativity in drawing, with creativity in writing and creativity in drawing being least similar. Additionally, we found evidence for several underlying traits (i.e., literacy ability and mathematical ability) and initial requirements of creativity (i.e., intelligence and divergent thinking), none of which were important for creativity in only one domain, and of which only intelligence was important for creativity in all domains. Herewith, our study provides insights regarding the complexity of the structure of creativity in primary education.     

Top Ten Questions Male Sexual Abuse Survivors Want to Know from Health Care Research

Sexual abuse is an often overlooked public health issue for boys and men. Given its prevalence and well-documented connection to mental and physical health disorders, the relevance of male survivor input and engagement in health care research is profound. Using a community-based participatory research design, an in-person focus group with male survivors of sexual abuse and researchers was conducted. This paper describes the top ten research questions male sexual abuse survivors would like to have answered. Survivors were most interested in knowing how sexual abuse and assault impact men’s emotional and sexual functioning, what factors are involved in preventing and treating sexual assault-related emotional distress, and what can be done to prevent sexual abuse of boys and men. The fact that some of the questions survivors expressed an interest in knowing about have actually previously been investigated by researchers suggests a disconnect in translating evidence-based findings. Clinical and research implications include designing outreach interventions and gender-specific psychoeducation to increase engagement and access to care for men.     

Psychopathic traits associated with abnormal hemodynamic activity in salience and default mode networks during auditory oddball task

Psychopathy is a personality disorder accompanied by abnormalities in emotional processing and attention. Recent theoretical applications of network-based models of cognition have been used to explain the diverse range of abnormalities apparent in psychopathy. Still, the physiological basis for these abnormalities is not well understood. A significant body of work has examined psychopathy-related abnormalities in simple attention-based tasks, but these studies have largely been performed using electrocortical measures, such as event-related potentials (ERPs), and they often have been carried out among individuals with low levels of psychopathic traits. In this study, we examined neural activity during an auditory oddball task using functional magnetic resonance imaging (fMRI) during a simple auditory target detection (oddball) task among 168 incarcerated adult males, with psychopathic traits assessed via the Hare Psychopathy Checklist-Revised (PCL-R). Event-related contrasts demonstrated that the largest psychopathy-related effects were apparent between the frequent standard stimulus condition and a task-off, implicit baseline. Negative correlations with interpersonal-affective dimensions (Factor 1) of the PCL-R were apparent in regions comprising default mode and salience networks. These findings support models of psychopathy describing impaired integration across functional networks. They additionally corroborate reports which have implicated failures of efficient transition between default mode and task-positive networks. Finally, they demonstrate a neurophysiological basis for abnormal mobilization of attention and reduced engagement with stimuli that have little motivational significance among those with high psychopathic traits.     

The language and social background questionnaire: Assessing degree of bilingualism in a diverse population

Research examining the cognitive consequences of bilingualism has expanded rapidly in recent years and has revealed effects on aspects of cognition across the lifespan. However, these effects are difficult to find in studies investigating young adults. One problem is that there is no standard definition of bilingualism or means of evaluating degree of bilingualism in individual participants, making it difficult to directly compare the results of different studies. Here, we describe an instrument developed to assess degree of bilingualism for young adults who live in diverse communities in which English is the official language. We demonstrate the reliability and validity of the instrument in analyses based on 408 participants. The relevant factors for describing degree of bilingualism are: (1) the extent of non-English language proficiency and use at home, and (2) non-English language use socially. We then use the bilingualism scores obtained from the instrument to demonstrate their association with: (1) performance on executive function tasks, and (2) previous classifications of participants into categories of monolinguals and bilinguals.
