What is specific about category specificity? Fractionating patterns of impairments and the spurious living/nonliving dichotomy
No full textWhat aspects of the data from studies of acquired category-specific impairments are relevant to theories of knowledge representation? Discussion in the target article focuses on the living/nonliving dichotomy. However, many case studies reveal consiserably more complex patterns of impaired and preserved performance that undermine this distinction. We consider this evidence and discuss its implications for theories of knowledge representation.</p

Pothos mirabilis is endemic to Sabah and is unique from its flower, its enormously elongated and twisted pendent spathe. Pothos mirabilis is allied to Pothos volans P.C.Boyce & A.Hay and Pothos wallichii Hook. f. due to its inflorescences are mostly produced from the tips of leafy shoots and this together with the long slender peduncle (Boyce 2000).

Identification. Pothos beccarianus is endemic to Borneo (not yet recorded from Kalimantan) and belongs to the Goniurus supergroup. Pothos beccarianus is recognized for its frequently long, pubescent inflorescences with the flowers set directly on the spadix axis and not on a swollen pad. This species is variable in size and the development of its inflorescence is closely linked to the vigour of the plant or even of an individual branch (300% size difference). Pothos beccarianus has two different types of inflorescences colour, yellow (common) and dark pink (rare) (Boyce and Hay 2001). Distribution and ecology. Southwestern and northeastern Sabah. Primary to variously disturbed lowland to hill forest, on slopes and ridgetops, very occasionally in kerangas, 135–820 m elev.Published as part of Wong, Sin Yeng & Joling, Jyloerica, 2021, Checklist of aroids (Alismatales, Araceae) from Sabah (Malaysian Borneo), pp. 931-974 in Check List 17 (3) on page 955, DOI: 10.15560/17.3.93
One or two dimensions in spontaneous classification: A simplicity approach
No full textWhen participants are asked to spontaneously categorize a set of items, they typically produce unidimensional classifications, i.e., categorize the items on the basis of only one of their dimensions of variation. We examine whether it is possible to predict unidimensional vs. two-dimensional classification on the basis of the abstract stimulus structure, by employing Pothos and Chater’s simplicity model of spontaneous categorization [Pothos, E. M., & Chater, N. (2002). A simplicity principle in unsupervised human categorization. Cognitive Science, 26, 303–343]. The simplicity model provides a quantitative measure of how intuitive a particular classification is. With objects represented in two dimensions, we propose that a unidimensional classification will be preferred if it is more intuitive than all possible two-dimensional ones, and vice versa. Empirical results supporting this proposal are reported. Implications for Goodman’s paradox are discussed

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Southern windows proved to be superior to Eastern, Western, Northern windows regarding plant height, number of leaves per plant, leaf size, stem diameter and root length.

The triangle inequality constraint in similarity judgments
No full textSince Tversky's (1977) seminal investigation, the triangle inequality, along with symmetry and minimality, have had a central role in investigations of the fundamental constraints on human similarity judgments. The meaning of minimality and symmetry in similarity judgments has been straightforward, but this is not the case for the triangle inequality. Expressed in terms of dissimilarities, and assuming a simple, linear function between dissimilarities and distances, the triangle inequality constraint implies that human behaviour should be consistent with Dissimilarity (A,B) + Dissimilarity (B,C) ≥ Dissimilarity (A,C), where A, B, and C are any three stimuli. We show how we can translate this constraint into one for similarities, using Shepard's (1987) generalization law, and so derive the multiplicative triangle inequality for similarities, Sim(A,C)≥Sim(A,B)(dot operator)Sim(B,C) where 0≤Sim(x,y)≤1. Can humans violate the multiplicative triangle inequality? An empirical demonstration shows that they can
