Models that allow us to perceive the world more accurately also allow us to remember past events more accurately via differentiation

Differentiation is a theory that originally emerged from the perception literature and proposes that with experience, the representation of stimuli becomes more distinct from or less similar to the representation of other stimuli. In recent years, the role of differentiation has played a critical role in models of memory. Differentiation mechanisms have been implemented in episodic memory models by assuming that information about new experiences with a stimulus in a particular context accumulates in a single memory trace and these updated memory traces become more distinct from the representations of other stimuli. A key implication of such models is that well encoded events are less confusable with other events. This prediction is particularly relevant for two important phenomena. One is the role of encoding strength on memory. The strength based mirror effect is the finding of higher hit rates and lower false alarm rates for a list composed of all strongly encoded items compared to a list composed of all weakly encoded items. The other is output interference, the finding that accuracy decreases across a series of test trials. Results from four experiments show a tight coupling between these two empirical phenomena such that strongly encoded target items are less prone to interference. By proposing a process model and evaluating the predictions of the model, we show how a single theoretical principle, differentiation, provides a unified explanation for these effects.     

The Effect of Fiction on Religious Studies Display Shelves in an Academic Library

Abstract

The religious studies librarians at Brigham Young University (BYU) began a book display research project to examine the circulation rates of religious studies titles placed on display and to specifically evaluate the impact of religious fiction on that display in an academic library. Student employees were tasked with curating the displays over several years and maintaining a spreadsheet with the titles displayed and resulting checkout rates. Religious fiction (from The Church of Jesus Christ of Latter-day Saint tradition) circulated over 80% the first three years, higher than the religious nonfiction on display and the same genre in the stacks. In the final year of study when almost no fiction was displayed and a higher quantity of items were placed on the shelves, the display circulation rates fell sharply. All books on the display circulated better when there was a portion of both nonfiction and fiction and when the shelves held fewer items. The data clearly showed that religious fiction is an important genre to display in an academic library.

The case for characterising type-2 blindsight as a genuinely visual phenomenon

Type-2 blindsight is often characterised as involving a non-visual form of awareness that blindsight subjects experience under certain presentation conditions. This paper evaluates the claim that type-2 awareness is non-visual and the proposal that it is a cognitive form of awareness. It is argued that, contrary to the standard account, type-2 awareness is best characterised as visual both because it satisfies certain criteria for being visual and because it can accommodate facts about the phenomenon that the cognitive account cannot. The conclusion is made that type-2 blindsight is best characterised as involving a form of abnormal, degraded visual awareness.     

Ginsborg on a Kantian-Brandomian View of Concepts

ABSTRACT

According to a Kantian-Brandomian view of concepts, we can understand concepts in terms of norms or rules that bind those who apply them, and the use of a concept requires that the concept-user be sensitive to the relevant conceptual norms. Recently, Ginsborg raises two important objections against this view. According to her, the normativity Brandom ascribes to concepts lacks the internalist or first-person character of normativity that Kant’s view demands, and the relevant normativity belongs properly not to concepts as such, but rather to belief or assertion. The purpose of this paper is to defend a Kantian-Brandomian view of concepts against these objections.     

Feature-processing deficits following brain injury. II. Classification learning, categorical decision making, and feature production

The claim that overselectivity in feature processing underlies the disorders that aphasics display in processing both visual and verbal material was directly tested by exploring the relationships between the behavior of brain-injured subjects on three experimental tasks: classification learning, categorical decision making, and feature production. From each of these tests a score selected as being indicative of overselective responding was entered into a principal components analysis, together with measures of visual recognition and memory, visual reasoning, naming skills, and severity of aphasia. This analysis supported the assumption that feature-processing disability is a specific and separable deficit, although related both to naming ability and to severity of aphasia. The relevance of the overselectivity hypothesis to naming difficulties following brain injury is discussed.     

The home observation for measurement of the environment (HOME) scale: A review of research

Caldwell's Home Observation for Measurement of the Environment (HOME) scale is perhaps the most widely used instrument to assess the quality of a young child's home learning environment. In this paper, the HOME'S psychometric properties and methodological uses are explored, and its utility as a research and clinical instrument is examined. Strengths of the HOME scale include the relatively wide range of information available pertaining to its psychometric properties and its use in studies of a variety of populations for a variety of purposes. Weaknesses include the fact that most research relating HOME scores to later child development is correlational. Several suggestions for future research are offered.     

La reprise d’études universitaires : entre continuité et rupture

The presented study pursued the objective to analyze the dialectic break/continuity susceptible to cross the transition of resumption of studies to the university, of the decision-making in the real-life experience of the first one-month of training. For that purpose, two models were summoned, that of motivations Push/Pull, Antipush/Antipull of Mullet, Lunch, Lemaire, Raiff and Barthorpe (2000) and that of the transitional processes proposed by Perret-Clermont and Zittoun (2002), as well as the concept of perceived social support completed of the notion of perceived social brake. The analysis of semi-directive conversations led with 10 adults in resumption of studies in a university of Île-de-France first brought to the foreground four motivational, certain dynamics more marked with the seal of the break (early or consummate), others more registered in a professional continuity (to develop or to install). Then, the analysis identified the most notable upheavals of the experience of the first months of training (identity plan and management of the various spheres of activity). Finally, it appeared that the social supports perceived, although important throughout the transition, vary in nature and function in each of the two periods of transition studied (decision, beginning of training). The results are particularly discussed in terms of Amartya Sen's capability approach.     

The presence of the absence in Kjell Westö’s novel: “Hägring 38”

ABSTRACT

The word ‘hägring’ (in English. ‘mirage’) can be understood in different ways: as an unrealistic hope or wish that cannot be achieved (wishful thinking); as an image in a mirror of something that is not there, but in another place, and as a sign of something that has not yet become visible, for instance, the first rays of sunlight on the horizon before the sun has risen. These meanings represent different ways in which presence and absence interplay, and are all illustrated in Kjell Westö’s impressive novel from 2013 for which he received the Nordic Literature Prize in 2014.

The action of the novel takes place during eight months in Helsinki from March to November 1938 and unravels how the past and present are woven together on a historical, societal and individual level. The present article will try to illustrate this.
