Working memory retention systems: a state of activated long-term memory

High temporal resolution event-related brain potential and electroencephalographic coherence studies of the neural substrate of short-term storage in working memory indicate that the sustained coactivation of both prefrontal cortex and the posterior cortical systems that participate in the initial perception and comprehension of the retained information are involved in its storage. These studies further show that short-term storage mechanisms involve an increase in neural synchrony between prefrontal cortex and posterior cortex and the enhanced activation of long-term memory representations of material held in short-term memory. This activation begins during the encoding/comprehension phase and evidently is prolonged into the retention phase by attentional drive from prefrontal cortex control systems. A parsimonious interpretation of these findings is that the long-term memory systems associated with the posterior cortical processors provide the necessary representational basis for working memory, with the property of short-term memory decay being primarily due to the posterior system. In this view, there is no reason to posit specialized neural systems whose functions are limited to those of short-term storage buffers. Prefrontal cortex provides the attentional pointer system for maintaining activation in the appropriate posterior processing systems. Short-term memory capacity and phenomena such as displacement of information in short-term memory are determined by limitations on the number of pointers that can be sustained by the prefrontal control systems.     

Machiavellianism and Theory of Mind in people affected by schizophrenia

CONTEXT: People affected by schizophrenia show deficits in social interaction (Cramer, Bowen, & O'Neill, 1992); such a deficit may stem from an alteration in the representation of mental states. OBJECT: In this study we have examined 42 people affected by schizophrenia, diagnosed according to DSM-IV criteria, by testing them with an instrument (the Mach IV scale, Christie & Geis, 1970) assessing "Machiavellian Intelligence" according to Niccolò Machiavelli's assertions. Schizophrenic subjects were compared to a sample of normal controls, matched for age, sex, and education. OBJECTIVE: The aim of our study was to evaluate if there were correlations between the ability to understand other people's mental states and the capacity for interpreting "Machiavellian expressions." RESULTS: Results show that people affected by schizophrenia are less able to use Machiavellian-style "tactical" abilities than controls. CONCLUSION: Such a disability seems to be correlated to poor mentalising abilities.     

Food for Boys and Food for Girls: Do Preschool Children Hold Gender Stereotypes about Food?

Widening the temporal window: processing support in the treatment of aphasic language production

Investigations of language processing in aphasia have increasingly implicated performance factors such as slowed activation and/or rapid decay of linguistic information. This approach is supported by studies utilizing a communication system (SentenceShaper) which functions as a "processing prosthesis." The system may reduce the impact of processing limitations by allowing repeated refreshing of working memory and by increasing the opportunity for aphasic subjects to monitor their own speech. Some aphasic subjects are able to produce markedly more structured speech on the system than they are able to produce spontaneously, and periods of largely independent home use of SentenceShaper have been linked to treatment effects, that is, to gains in speech produced without the use of the system. The purpose of the current study was to follow up on these studies with a new group of subjects. A second goal was to determine whether repeated, unassisted elicitations of the same narratives at baseline would give rise to practice effects, which could undermine claims for the efficacy of the system.     

A Program to Select Sentences with a Strong Psychological Impact

This article presents a program based on the Elementary Pragmatic Model and on the administration of a test consisting of 90 sentences with a strong psychological impact interactively presented to participants. Data emerging from this procedure are calculated according to four coordinates and 16 relational functions processed on a grid defined by a table of 256 possible interactions. From these interactions three final states were found to constitute essentially the bottom line of the human mind. The program indicates how certain sentences could be selected systematically to lead initially deviant participants toward more statistically average patterns, in terms of coordinates, functions, interactions, and final states.     

Spontaneous imagined contact and intergroup relations: Quality matters

While research on experimental interventions that aim to improve outgroup attitudes via contact imagery grows, it is important to examine if contact imagery that occurs in spontaneous, non-experimentally controlled conditions drives attitudes, and in what direction. To answer this, we constructed and validated a spontaneous imagined intergroup contact scale (SIICS) that differentiates between frequency, quality and elaboration of the spontaneous imagery of outgroups. In three correlational studies (N_Portugal = 305, N_{United Kingdom} = 185, N_Italy = 276), we tested the role of spontaneous imagined contact frequency, quality and elaboration in predicting attitudes and social distance (Studies 1–3) and intended behaviour (Study 3) toward immigrant groups. Results demonstrated that spontaneous imagined contact quality consistently predicted key outcome variables above and beyond the other two dimensions. Importantly, the effects were significant while controlling for other potent forms of direct and indirect contact. Implications of the findings for theory and practice are discussed.     

Reflecting on Maltese school‐based counselling practices: An autoethnographic collaborative writing project

Maltese counsellors working in schools are, at times, just making ends meet due to lack of human resources and work schedules. ‘Why do our students/children have to repeat the same story to so many professionals?’ teachers/parents angrily query. This autoethnographic study voices our professional experiences as authors and participants. This empowers us to be advocates for our young clients. Collaborative autoethnography (CAE) methodology best fits our research question as we ‘seek to discover and systemically analyze (graphy) personal experience (auto)…understand cultural experience (ethno)’ (Ellis, Adams, & Brochner, 2011, p. 273). Our writing and reflections conclude that best practices include counsellors who work, at least, in pairs within transdisciplinary teams at one school for cycles of five years, with clarity of roles across professionals.
