Is the impaired N170 print tuning specific to developmental dyslexia? A matched reading-level study with poor readers and dyslexics

Left N170 print tuning has been associated with visual expertise for print and has been reported to be impaired in dyslexics, using age matched designs. This is the first time N170 print tuning has been compared in adult dyslexics and adult poor readers, matched in reading level. Participants performed a lexical decision task using both word-like stimuli and symbol strings. In contrast to dyslexics, poor readers displayed similar N170 tuning to control expert readers, suggesting that impaired N170 specialization is a hallmark of developmental dyslexia. Our findings provide electrophysiological support for dyslexia being the result of abnormal specialization of the left occipito-temporal areas involved in the expert processing of print. Furthermore, as shown by correlations data and in accordance with the phonological mapping deficit theory, the impaired visual expertise for print described in dyslexics may have been caused by their core phonological deficits.     

In the shadow of giants: The work of mario pieri in the foundations of mathematics

A discussion is given of the research in the foundations of mathematics of Mario Pieri (1860-1913) and how it compares with the works of Christian von Staudt (1798-1867), Giuseppe Peano (1858-1932), David Hubert (1862-1943), and Alfred Tarski (1902-1983). The author demonstrates that the acceptance of Pieri’s results was overshadowed by the research of these four scholars, and argues that Pieri’s work merits a more significant place in the history of mathematics than it currently enjoys     

A Qualitative Study of Community–University Partnerships That Support Psychosocial Occupational Therapy

Community partner voices are important to understand because they provide the contexts in which occupational therapy (OT) students research community-identified needs and together, create evidence-based occupation-focused programs while developing clinical reasoning skills in a natural context. The purpose of this study is to understand how community partners experienced partnerships that support community-based research in psychosocial settings. This retrospective study explores the perspectives of community partners that hosted OT students for two-semester service-learning project over 3 years. Findings revealed partners value effective communication with faculty and students, spending time observing, listening, and developing meaningful relationships with clients and staff.     

'What did we talk about last week?' a study of forgetting in one schizophrenic and two borderline clients in counselling

Abstract

This paper describes ‘forgetting between sessions’ by two borderline and one schizophrenic client in counselling. What was forgotten included: progress made, awareness of dependence, an experience of having a helpful and sympathetic counsellor, and the ability to think. Understanding of this phenomenon is explored in terms of schizoid mechanisms (Klein 1946), omnipotent narcissistic object relations (Rosenfeld 1987) and attacks on linking and thinking (Bion 1959, 1962). The need to avoid or evacuate painful experiences which are intolerable to the individual, or to recreate and remember existentially infantile traumata, are proposed to be some of the reasons behind this forgetting. The counsellor's capacity to remember, forget, contain, and think about the client's experiences is considered.     

Filling the Gap on Developmental Change: Tests of a Dynamic Field Theory of Spatial Cognition

In early childhood, there is a developmental transition in spatial memory biases. Before the transition, children's memory responses are biased toward the midline of a space, while after the transition responses are biased away from midline. The Dynamic Field Theory (DFT) posits that changes in neural interaction and changes in how children perceive frames of reference underlie the transition. Here, we tested a prediction of the DFT that children younger than the transitional age would show the more advanced developmental pattern when tested with a perceptually salient midline axis. Four age groups (3 years, 6 months; 3 years, 8 months; 4 years; and 5 years) were tested at targets near midline. As predicted, children's responses were biased away from midline.     

Social Identity-Specific Collectivism (SISCOL) and Group Behavior

Assessment of collectivism has, for the most part, targeted interpersonal (often dyadic) relationships, e.g., spouse or friend. The multifactor social identity-specific collectivism (SISCOL) scale is an alternative approach that targets groups or categories (e.g., ethnic, political). In this study, the relationship between SISCOL and reported group behavior (political action, group participation, leisure activity) was explored. First, SISCOL varied in a meaningful and predictable way as a function of group membership. Second, SISCOL subscales were divergently predictive: social identity, b=.31, and common fate, b=.18, predicted political action; social identity, b=.22, emotional attachment, b=.32, and group norms, b=.20, predicted group participation. The importance and utility of a group targeted approach is discussed.     

Perceptions of Humility: A Preliminary Study

Do people perceive humility as a strength or a weakness? The current study examined this question in a sample of 127 undergraduates. Contrary to common dictionary definitions of humility, which often emphasize its association with self-abasement, participants reported consistently positive views of humility. When recalling situations in which they felt humble, they typically reported success experiences associated with positive emotion. Participants clearly associated humility with good psychological adjustment, although they were less decisive about whether humility was associated with confidence or leadership. Although participants viewed humility as a strength across all social roles sampled, humility was viewed most favorably as a quality of religious seekers, less favorably as a quality of close others or subordinates, and least favorably as a quality of leaders or entertainers. Positive views of humility were associated with high self-esteem and religiosity. Less favorable views of humility were associated with narcissism—particularly its exploiting/entitled dimension.     

Generalized Schedule Following in a Youth with Autism

Abstract

Photographic activity schedules were used to increase on-task behaviour in a youth with autism. The multiple probe design included baseline, training, tests for training effects, resequencing of photographs, generalization to new photographs, and maintenance. The results showed that the participant was able to carry out four different chains (photographic activity schedules) without any prompts from the staff, even when the photographs were resequenced, and new photographs were included. On the other hand, there was no reduction of training trials to reach criterion from the first to the fourth chain. The results are discussed with reference to different aspects of generalization.
