Rejection of False Events in Childhood: A Metamemory Account

ABSTRACT— Knowing how to identify events that we never experienced is an important skill: This ability enables us to reject such events as part of our past and thus reduces the risk of creating false memories. Recent research highlights the involvement of metamemory processes in this domain. I review empirical evidence pertaining to the functioning and development of the memorability-based strategy, a specific mechanism rooted in metamemory. The substantial development of this mechanism during childhood can provide an account for children's vulnerability to false-memory formation.     

Die Unaufrichtigkeit als Neurose und als Verbrechen

Zusammenfassung. Die Autorin stellt einige überlegungen bezüglich einer arglistigen, sch?dlichen und, ihrem Eindruck nach, heutzutage weit verbreiteten Pathologie vor, die sich von F?llen entschiedener klinischer H?rte bis zu anderen an der Grenze der Normalit?t, erstreckt. Sie verwendet von Beginn an den Terminus der Unaufrichtigkeit (italienisch: malafede; spanisch: mala fe’), den sie von Madeleine Baranger entlehnt, wobei sie betont, dass er der Bedeutung der von ihr vorgestellten St?rung nur ann?herungsweise entspricht. Ausgangspunkt für ihre überlegungen bildeten Behandlungsschwierigkeiten mit Patienten, die stark widersprüchliche Aspekte in sich vereinigten, ohne Anzeichen von Konfliktualit?t oder Unbehagen zu manifestieren. Diese Besonderheit tritt vor allem bezüglich moralischer Fragestellungen in Erscheinung, bezüglich abstrakter Moralvorstellungen oder Ideologien, die von einigen Patienten in scharfem Kontrast zu ihrem Verhalten und ihren Gefühlen verkündet werden.

Dishonesty as a neurosis and as a crime

Summary. In this essay, reflections about a malicious and in the view of the author nowadays wide-spread pathology are presented. It occurs in a large variety of forms from serious clinical disturbances to almost-normality. The author designates this pathology by the term „dishonesty”, a term borrowed from Madeleine Baranger, emphasizing however, that it is merely an approximation to the presented disorder. The starting-point for her reflections were the difficulties she has experienced with patients having strongly contradictory aspects in their personality without the slightest sign of conflict or uneasiness. This peculiarity manifested itself first of all in moral questions as a contradiction between the abstract moral concepts and ideologies and the behaviour and emotions of the patient.

     

Perceiving one's nation: entitativity, agency and security in the international arena

The perception of groups as real entities rather than mere aggregates of individuals has important consequences on intergroup relations. Social psychological research, in fact, shows that it affects stereotyping, identification process, and intergroup bias. Previous research has also shown that group entitativity is not a positive or negative group attribute per se; rather, it depends on the context and the relationship between the perceiver and the group. While enhancing entitativity leads to worse expectations about the out‐group actions, high entitativity is a valued characteristic when associated with an ally or with the in‐group. Indeed, enhancing in‐group entitativity leads to stronger in‐group identification. The specific reasons for why this is the case, however, remain to be ascertained. What is good about in‐group entitativity? In the present contribution we propose that in‐group entitativity may lead to perceive the group as a real entity provided with intentions and capacity for planned actions, notably ensuring the safety of its members by protecting them against external threats. We report two correlational studies conducted with American citizens (Study 1) and Italian citizens (Study 2), showing that in‐group entitativity is associated with a higher level of identification, attribution of intentionality, and perceived security provided by the in‐group. These findings were replicated in a third study—conducted with a role‐play method on a fictitious scenario—in which entitativity was manipulated rather than measured. Study 3 also shows that artificially increasing the perception of in‐group entitativity enhances perceived safety in an international context and reduces the perception of threat from an out‐group. Findings are discussed in terms of possible implications for intergroup and international relations.     

Stimulus-driven attentional capture: An empirical comparison of display-size and distance methods

Four experiments examined attentional capture by colour as assessed by two different investigative methods. Subjects performed a visual search task for a vertical-target line embedded among tilted-distractor lines, presented inside 4, 8, or 12 coloured discs. Interestingly, when the colour singleton was task irrelevant, and data were analysed by means of the display-size method combined with the zero-slope criterion, no evidence for attentional capture by colour was found. However, when data were analysed by means of the distance method, which consists of monitoring the spatial relationship between the target and the singleton, results showed that the target was found faster and/or more accurately when it was inside the singleton than when it was in a nonsingleton location. This provided evidence for a stimulus-driven attentional capture. In addition, the application of signal detection methodology showed that attentional capture, as revealed by the distance method, resulted from a perceptual modulation at the singleton location, rather than from a criterion shift. We conclude that, at least with the kind of stimuli used here, the display-size method combined with the zero-slope criterion is less than ideal for investigating how static discontinuities can affect the automatic deployment of visual attention.     

Lambda Calculus and Intuitionistic Linear Logic

The introduction of Linear Logic extends the Curry-Howard Isomorphism to intensional aspects of the typed functional programming. In particular, every formula of Linear Logic tells whether the term it is a type for, can be either erased/duplicated or not, during a computation. So, Linear Logic can be seen as a model of a computational environment with an explicit control about the management of resources.This paper introduces a typed functional language ! and a categorical model for it.The terms of ! encode a version of natural deduction for Intuitionistic Linear Logic such that linear and non linear assumptions are managed multiplicatively and additively, respectively. Correspondingly, the terms of ! are built out of two disjoint sets of variables. Moreover, the -abstractions of ! bind variables and patterns. The use of two different kinds of variables and the patterns allow a very compact definition of the one-step operational semantics of !, unlike all other extensions of Curry-Howard Isomorphism to Intuitionistic Linear Logic. The language ! is Church-Rosser and enjoys both Strong Normalizability and Subject Reduction.The categorical model induces operational equivalences like, for example, a set of extensional equivalences.The paper presents also an untyped version of ! and a type assignment for it, using formulas of Linear Logic as types. The type assignment inherits from ! all the good computational properties and enjoys also the Principal-Type Property.     

A small step for rats alters spatial behavior: rats on a bi-level arena explore each level separately

Animal Cognition - We tested rats on a ‘bi-level open-field’ whose two halves were separated vertically by an 8-cm step that the rats could easily ascend/descend. We sought to determine...     

Scaffolding emotions and evolving language

We suggest that, in animals, the core-affect system is linked to partially assimilated behavioral dispositions that act as developmental scaffolds for the ontogenetic construction of emotions. We also propose that in humans the evolution of language altered the control of emotions, leading to categories that can be adequately captured only by emotion-words.
