Age-Specific Effects of Lexical–Semantic Networks on Word Production

The lexical–semantic organization of the mental lexicon is bound to change across the lifespan. Nevertheless, the effects of lexical–semantic factors on word processing are usually based on studies enrolling young adult cohorts. The current study aims to investigate to what extent age-specific semantic organization predicts performance in referential word production over the lifespan, from school-age children to older adults. In Study 1, we conducted a free semantic association task with participants from six age-groups (ranging from 10 to 80 years old) to compute measures that capture age-specific properties of the mental lexicon across the lifespan. These measures relate to lifespan changes in the Available Richness of the mental lexicon and in the lexical–semantic Network Prototypicality of concrete words. In Study 2, we used the collected data to predict performance in a picture-naming task on a new group of participants within the same age-groups as for Study 1. The results show that age-specific semantic Available Richness and Network Prototypicality affect word production speed while the semantic variables collected only in young adults do not. A richer and more prototypical semantic network across subjects from a given age-group is associated with faster word production speed. The current results indicate that age-specific semantic organization is crucial to predict lexical–semantic behaviors across the lifespan. Similarly, these results also provide cues to the understanding of the lexical–semantic properties of the mental lexicon and to lexical selection in referential tasks.     

Demonstrating detail in investigative interviews—An examination of the DeMo technique

Attaining an uninterrupted free report (FR) is at the heart of best practice investigative interviewing guidance. However, witnesses/victims do not naturally provide detailed accounts. Techniques have been developed to counter-act this, such as a report everything (RE) instruction. This research examined the relative effectiveness of an addition to the RE component, a demonstration of the level of detail, using a behavioural exemplar, by describing an innocuous object; the Demonstration for More detail (DeMo) technique. Participants (N = 61) watched a mock crime video and asked to recall it using one of three instructions: (a) basic FR as the control, (b) RE instruction and (c) RE instruction plus DeMo technique. Participants who were given the DeMo technique recalled more details than both the control and RE groups. Accuracy rates were similarly high across all conditions. The implications of using the DeMo technique within an investigative interview are discussed.     

身体拥有感及其可塑性：基于内外感受研究的视角

身体自我表征中的身体拥有感(即我的身体属于我的感受)问题一直是自我意识研究的核心话题。大量的已有研究表明, 身体拥有感的体验涉及不同感官信号的整合, 当前大多数研究只重视视觉、触觉等外感受的作用, 一方面忽视了内感受的作用, 另一方面也缺乏对两类感受整合的关注。橡胶手错觉实验和身体障碍患者身上所表现出的外感受和内感受对身体拥有感的影响支持了身体拥有感的可塑性假设, 自由能量原理认为身体拥有感形成的基础是大脑不断评估更新可能性表征来维持稳定。未来的研究需要从改善内感受的测量和刺激呈现方法, 探索影响内感受的高阶认知因素以及关注某些神经症患者的内感受等方面寻求突破。     

GROUP FORAGING SENSITIVITY TO PREDICTABLE AND UNPREDICTABLE CHANGES IN FOOD DISTRIBUTION: PAST EXPERIENCE OR PRESENT CIRCUMSTANCES?

The ideal free distribution theory (Fretwell & Lucas, 1970) predicts that the ratio of foragers at two patches will equal the ratio of food resources obtained at the two patches. The theory assumes that foragers have "perfect knowledge" of patch profitability and that patch choice maximizes fitness. How foragers assess patch profitability has been debated extensively. One assessment strategy may be the use of past experience with a patch. Under stable environmental conditions, this strategy enhances fitness. However, in a highly unpredictable environment, past experience may provide inaccurate information about current conditions. Thus, in a nonstable environment, a strategy that allows rapid adjustment to present circumstances may be more beneficial. Evidence for this type of strategy has been found in individual choice. In the present experiments, a flock of pigeons foraged at two patches for food items and demonstrated results similar to those found in individual choice. Experiment 1 utilized predictable and unpredictable sequences of resource ratios presented across days or within a single session. Current foraging decisions depended on past experience, but that dependence diminished when the current foraging environment became more unpredictable. Experiment 2 repeated Experiment I with a different flock of pigeons under more controlled circumstances in an indoor coop and produced similar results.     

Art, dreams and active imagination: a post-Jungian approach to transference and the image

The term active imagination is sometimes applied rather uncritically to describe all forms of creative activity that take place in depth psychology. Whilst there are many forms of expression that evoke or are evoked by active imagination, they cannot automatically be classed as active imagination. In this article investigation of visualized mental imagery, dreams and art reveals three distinct forms of image-based psychological activity. Integrated and mediated within the transference and countertransference dynamic, it is proposed that the engagement in active imagination reflects and is influenced by the transference. Distinctions between sign and symbol, simple and big dreams as well as diagrammatic and embodied imagery clarify the differences. Examples from clinical practice demonstrate each mode in action within the analytic frame.     

Admissibility of Cut in <Emphasis Type="Italic">LC</Emphasis> with Fixed Point Combinator

The fixed point combinator (Y) is an important non-proper combinator, which is defhable from a combinatorially complete base. This combinator guarantees that recursive equations have a solution. Structurally free logics (LC) turn combinators into formulas and replace structural rules by combinatory ones. This paper introduces the fixed point and the dual fixed point combinator into structurally free logics. The admissibility of (multiple) cut in the resulting calculus is not provable by a simple adaptation of the similar proof for LC with proper combinators. The novelty of our proof—beyond proving the cut for a newly extended calculus–is that we add a fourth induction to the by-and-large Gentzen-style proof. Presented by Robert Goldblatt     

Welfare and Wealth, Poverty and Justice in Today’s World

This article argues that there is no sound basis for thinking that we have a general and strong duty to rectify disparities of wealth around the world, apart from the special case where some become wealthy by theft or fraud. The nearest thing we have to a rational morality for all has to be built on the interests of all, and they include substantial freedoms, but not substantial entitlements to others assistance. It is also pointed out that the situation of the worlds poor is not that of victims of disasters, but simply of less-developed technology, which can be repaired by full and free trade relations with others. The true savior of the worlds poor is the businessman, not the missionary. What we do need to do is strike down barriers to commerce, rather than requisition aid.     

Free Łukasiewicz and Hoop Residuation Algebras

Hoop residuation algebras are the {, 1}-subreducts of hoops; they include Hilbert algebras and the {, 1}-reducts of MV-algebras (also known as Wajsberg algebras). The paper investigates the structure and cardinality of finitely generated free algebras in varieties of k-potent hoop residuation algebras. The assumption of k-potency guarantees local finiteness of the varieties considered. It is shown that the free algebra on n generators in any of these varieties can be represented as a union of n subalgebras, each of which is a copy of the {, 1}-reduct of the same finite MV-algebra, i.e., of the same finite product of linearly ordered (simple) algebras. The cardinality of the product can be determined in principle, and an inclusion-exclusion type argument yields the cardinality of the free algebra. The methods are illustrated by applying them to various cases, both known (varieties generated by a finite linearly ordered Hilbert algebra) and new (residuation reducts of MV-algebras and of hoops).     

Nonparametric IRT: Testing the bi-isotonicity of isotonic probabilistic models (ISOP)

Nonparametric tests for testing the validity of polytomous ISOP-models (unidimensional ordinal probabilistic polytomous IRT-models) are presented. Since the ISOP-model is a very general nonparametric unidimensional rating scale model the test statistics apply to a great multitude of latent trait models. A test for the comonotonicity of item sets of two or more items is suggested. Procedures for testing the comonotonicity of two item sets and for item selection are developed. The tests are based on Goodman-Kruskal's gamma index of ordinal association and are generalizations thereof. It is an essential advantage of polytomous ISOP-models within probabilistic IRT-models that the tests of validity of the model can be performed before and without the model being fitted to the data. The new test statistics have the further advantage that no prior order of items or subjects needs to be known.
