Interpersonal hierarchy expectation: introduction of a new construct

The goal of these series of studies was to introduce a new individual difference construct, interpersonal hierarchy expectation (IHE), and to show that it predicts interpersonal perception. IHE means expecting social interactions and relationships to be hierarchically structured. I developed a self-report questionnaire to measure IHE (IHE Scale [IHES]). In 5 studies, 581 undergraduates took the IHES together with an array of self-report personality measures. Three studies included a measure of hierarchy perception. According to prediction, people who expected interpersonal hierarchies were prone to perceive hierarchies in interactions and relationships. The IHES is an easy to apply, short, self-report measure that might prove useful in personnel training and selection as well as in other studies of personality and social behavior.     

Classes and collections: Internal organization and resulting holistic properties

This work presents an analysis of a type of concept, the collection, not readily characterized by class inclusion models. Collections, the referents of collective nouns (e.g., pile, family, bunch), are argued to differ from classes in (a) how membership can be determined, (b) part-whole relationships, (c) internal structure, and (d) the nature of the higher order units they form. From this analysis, it is hypothesized that the psychological integrity of collections is greater than that of classes. Collections and objects, in contrast to classes, both require specified relationships among the parts and both result in a coherent psychological unit. It was suggested that objects form a relatively more stable unit than collections. Corresponding to this analysis the degree of psychological integrity is hypothesized to lead to different degrees of difficulty in making part-whole comparisons for objects, collections, and classes in modified Piagetian class-inclusion paradigms. The hypothesized difference in performance was found for collections and classes and an alternative linguistic explanation for the greater success with collections was eliminated. However, children performed equally well on tasks involving collections and objects, raising the possibility that when elements are organized into collections, they form psychological units which are as coherent as objects.     

Classes and collections: Conceptual organization and numerical abilities

Collections (e.g., forest, army) and classes (e.g., trees, soldiers) are natural concepts that differ in their organizational principles. Collections are organized into part-whole relations (e.g., trees are parts of a forest). Classes are organized according to class inclusion relations (e.g., oaks are kinds of trees). Because of their part-whole organization, collections are assumed to have greater psychological coherence than classes and therefore an advantage on tasks that require thinking about an aggregate as well as the individuals in it. Number requires aggregate analysis since it is a characteristic of sets, not of individuals. Four studies tested the hypothesized collection advantage in numerical reasoning tasks. In each, children viewed identical displays that were labeled with either class or collection terms. With perceptual input constant, the collection labels in contrast to the class labels promoted children's insight into certain numerical principles and facilitated the use of these principles in a variety of numerical tasks. Collection labels appear to induce a cognitive reorganization of importance to the child: the shift from inclusion to part-whole relations.     

Representing and Solving Arithmetic Word Problems: A Study of Developmental Interaction

This study investigated the developmental relationship between children's mental representations of the arithmetic change problem structure (the change problem schema) and their use of part-whole strategies to solve change problems. Two hypotheses were contrasted. The first suggests that part-whole knowledge is a prerequisite for the development of the change problem schema. The second suggests that the change problem schema provides a framework for the development of part-whole knowledge. Part-whole knowledge was inferred from children's abilities to solve the most difficult type of change problem, that with start set unknown. The change problem schema was inferred from children's abilities to anticipate completion of the "how many?" question when given all information about the problem except the question. Only children who used part-whole strategies performed at greater than chance levels on the question generation measure. Part-whole knowledge, therefore, was seen as a prerequisite for the change problem schema.     

SUBSTANCE: THINGS AND STUFFS

The categorial concepts of substance (thing) and substance (stuff) are described, and the conceptual relationships between things and their constitutive stuff delineated. The relationship between substance concepts, expressed by other count-nouns, and natural kind concepts is examined. Artefacts and their parts are argued to be substances, whereas parts of organisms are not. The confusions of seventeenth- and eighteenth-century philosophers who invoked the concept of substance are adumbrated.     

Selection of macroreference frames in spatial memory

Spatial memories are often hierarchically organized with different regions of space represented in unique clusters within the hierarchy. Each cluster is thought to be organized around its own microreference frame selected during learning, whereas relationships between clusters are organized by a macroreference frame. Two experiments were conducted in order to better understand important characteristics of macroreference frames. Participants learned overlapping spatial layouts of objects within a room-sized environment before performing a perspective-taking task from memory. Of critical importance were between-layout judgments thought to reflect the macroreference frame. The results indicate that (1) macroreference frames characterize overlapping spatial layouts, (2) macroreference frames are used even when microreference frames are aligned with one another, and (3) macroreference frame selection depends on an interaction between the global macroaxis (defined by characteristics of the layout of all learned objects), the relational macroaxis (defined by characteristics of the two layouts being related on a perspective-taking trial), and the learning view. These results refine the current understanding of macroreference frames and document their broad role in spatial memory.     

Part-whole science

A scientific explanatory project, part-whole explanation, and a kind of science, part-whole science are premised on identifying, investigating, and using parts and wholes. In the biological sciences, mechanistic, structuralist, and historical explanations are part-whole explanations. Each expresses different norms, explananda, and aims. Each is associated with a distinct partitioning frame for abstracting kinds of parts. These three explanatory projects can be complemented in order to provide an integrative vision of the whole system, as is shown for a detailed case study: the tetrapod limb. My diagnosis of part-whole explanation in the biological sciences as well as in other domains exploring evolved, complex, and integrated systems (e.g., psychology and cognitive science) cross-cuts standard philosophical categories of explanation: causal explanation and explanation as unification. Part-whole explanation is itself one essential aspect of part-whole science.     

An empirical comparison of Maslow's and Murray's needs systems

Summary: The Work Motivation Inventory (WMI), a measure of Maslow's hierarchy of needs, and the Edwards Personal Preference Schedule (EPPS), a measure of Murray's manifest needs, were administered to 372 undergraduates. The two instruments were compared using canonical analysis. The analysis revealed three significant relationships between components of the two instruments. The first relationship supported Maslow's need hierarchy in general and its measurement by the WMI. The second suggested a fluctuating relationship between giving and receiving help and the levels of Maslow's hierarchy. The third relationship sumested that need for Achievement is associated with the intermediate levels of Maslow's hierarchy.     

Abstract levels of motor control in prehension: Normal and pathological performance

Voluntary motor pattern generation is typically assumed to be organized hierarchically, with an abstract (effector independent) upper level which constrains the lower levels. There are at least two advantages of such an organization: it allows the system to exploit its redundancy, and when controlling a very large number of degrees of freedom the burden of control can be distributed over a sequence of stages. Experiments are reviewed which provide a consistent body of evidence in support of the contention that there is an effector independent level of motor representation in prehension. This is consistent with a hierarchically organized motor pattern generator. One set of experiments demonstrated that during active movement of a hand-held load, the coupling of grip force with movement induced load force is independent of how the load is grasped or how it is actively moved. A second set of experiments demonstrated that the movement patterns observed during reach-to-grasp are preserved over changes in the effector system used. Extensions and replications of these experiments with Parkinson's patients illustrates the idea that neurological problems may affect different levels of the control hierarchy suggesting that these levels may be anatomically as well as functionally distinguishable.PsycINFO classification: 2330; 2520; 3297     

The fluency of social hierarchy: the ease with which hierarchical relationships are seen, remembered, learned, and liked

We tested the hypothesis that social hierarchies are fluent social stimuli; that is, they are processed more easily and therefore liked better than less hierarchical stimuli. In Study 1, pairs of people in a hierarchy based on facial dominance were identified faster than pairs of people equal in their facial dominance. In Study 2, a diagram representing hierarchy was memorized more quickly than a diagram representing equality or a comparison diagram. This faster processing led the hierarchy diagram to be liked more than the equality diagram. In Study 3, participants were best able to learn a set of relationships that represented hierarchy (asymmetry of power)--compared to relationships in which there was asymmetry of friendliness, or compared to relationships in which there was symmetry--and this processing ease led them to like the hierarchy the most. In Study 4, participants found it easier to make decisions about a company that was more hierarchical and thus thought the hierarchical organization had more positive qualities. In Study 5, familiarity as a basis for the fluency of hierarchy was demonstrated by showing greater fluency for male than female hierarchies. This study also showed that when social relationships are difficult to learn, people's preference for hierarchy increases. Taken together, these results suggest one reason people might like hierarchies--hierarchies are easy to process. This fluency for social hierarchies might contribute to the construction and maintenance of hierarchies.     

Attachment and the Emotional Unit

Until recently, the mother-child relationship was assumed to be the primary relationship affecting the outcome of an individual. This resulted in the mother-child dyad being seen and studied as separate from the family system in which it is embedded. This article asserts that, in order to understand this dyad adequately, one must understand "how" the family functions as an emotional unit that is guided by processes found in evolution and in relationships between living things. It goes beyond describing the family as a system of influence and seeks to account for the universal processes that occur in natural systems. It posits that the triangle is the basic building block of the emotional unit, and proposes a new theoretical dimension for understanding how attachment extends beyond dyads (such as parent-child) to include the emotional unit as a whole. Through triangles, the parent-child relationship is continually influenced by relationship forces operating within the system as a whole.     

When and why hierarchy steepness is related to team performance

This study develops and tests a contingency theory on the functions of status hierarchy steepness in teams. Findings from a field study among 438 employees working in 72 work teams across diverse business settings demonstrate that task complexity moderates the relationships between status hierarchy steepness, different types of team conflict, and team performance. Steeper status hierarchies were negatively related to both process and task conflict, and hence increased team performance in teams working on tasks with lower complexity but did not yield such clear conflict and performance effects in teams working on more complex tasks. By showing that various levels of task complexity determine whether status hierarchy steepness has a conflict-regulating function that drives team performance, this research generates valuable insights about the context dependency of team responses to status hierarchy steepness.     

Successful part-whole perception in young children using multiple-choice tests.

In 3 experiments involving young children (N = 164), excellent perceptual integration of parts and wholes was revealed, unlike findings of earlier Piagetian studies (D. Elkind, R. R. Koegler, & E. Go, 1964). In Experiment 1, 5-year-olds' performance in part-whole perception was raised nearly sixfold when a multiple-choice task was substituted for the Piagetian verbal task used earlier. Performing the multiple-choice first rather than second also raised verbal scores. Experiment 2, with 3- to 5-year-olds, tested whether the children could have been confusing "whole made of parts" with "whole and parts" stimuli. Equal performance was found with 2 versions of a multiple-choice task, including either a whole and parts or a whole and different parts picture, which contradicts the confusion hypothesis. In Experiment 3, with 2- to 4-year-olds, good part-whole perception was demonstrated through the use of a 2-alternative, forced-choice procedure. The lower age bounds for this type of performance are much earlier than hitherto proposed.     

Development of hierarchical conceptual relationships in children's semantic memories

The present study was designed to determine when children first display evidence of hierarchical conceptual organization. Children aged 5 to 9 answered either semantic or sensory questions about a list of words composed of either superordinate terms, prototypical category instance, or moderately typical instances. In a later unanticipated cued recall task the children were given taxonomically related cues composed of the two remaining word types not used in the orienting phase. The 5-year-olds' performance revealed that they possessed a modest degree of hierarchically organized conceptual information, which by age 9 had developed to relatively sophisticated levels. In particular, it was found that the range of information contained in the 5-year-olds' conceptual hierarchies was considerably narrower than that of the 9-year-olds', which supports Rosch's contention that conceptual categories are first constructed around prototypical instances. The children's performance on the cued recall task was also compared to their performance on traditional class inclusion and object-sorting tasks. It was found that the object-sorting task overestimated, while the class inclusion task underestimated the extent to which conceptual information is hierarchically organized in 5-year-olds.     

Global and local precedence: selective attention in form and motion perception

This study explores the perception of stimuli at two levels: local parts and the wholes that comprise these parts. Previous research has produced contradictory results. Some studies (e.g., Pomerantz & Sager, 1975) show local precedence, in which the local parts are more difficult to ignore in selective attention tasks. Other studies (e.g., Navon, 1977) have shown the opposite effect, global precedence. The present five experiments trace the causes of this discrepancy by exploring the effects of the relative discriminabilities of the local and global levels of the stimuli and the differences between two different measures of selective attention, namely, Stroop-type interference (attributable to incongruity on the irrelevant dimension) and Garner-type interference (attributable to variability on the irrelevant dimension). The experiments also examine whether the precedence effects previously examined in form perception generalize to motion perception. The results show that (a) some cases of global precedence are due solely to the greater perceptual discriminability of the global level and thus demonstrate only that more discriminable stimuli are harder to ignore; (b) instances of both local and global precedence can be demonstrated for certain types of stimuli, even when the discriminabilities of their local and global levels have been equated; and (c) the Stroop and Garner measures of selective attention are not equivalent but instead measure different types of interference. In addition, a distinction is made between two fundamentally different types of part-whole relationships that exist in visual configurations, one based only on the positions of the parts (Type P) and one based also on the nature of the parts (Type N). Previous research has focused on Type P, which appears to be irrelevant to the broader questions of Gestalt and top-down effects in perception. It is concluded that bona fide cases of both local and global precedence have been amply documented but that no general theory can account for why or when these effects will appear until we better understand both the nature of part-whole relationships and the perceptual processes that are tapped by different measures of selective attention.     

Social dominance and interpersonal power: Asymmetrical relationships within hierarchy‐enhancing and hierarchy‐attenuating work environments

We studied whether high‐social dominant employees sustain hierarchies in different hierarchy‐enhancing and hierarchy‐attenuating organizations endorsing harsh and soft power tactics. We found that social dominance orientation was positively associated with harsh power tactics, and negatively associated with soft power tactics. Employees higher in social dominance orientation endorsed harsh and opposed to soft power tactics as respectively hierarchy‐enhancing and hierarchy‐attenuating legitimizing myths that promote a dominant‐submissive form of intergroup relationships. We also found that supervisors higher in social dominance, due to their dominant position, strongly opposed soft power tactics more than subordinates did. Amongst high‐social dominant employees in the hierarchy‐attenuating (vs. hierarchy‐enhancing) organization, we observed the strongest opposition to soft power tactics, which are the tactics most shared in an organization which tends to attenuate hierarchies.     

Crowded and sparse domains in object recognition: consequences for categorization and naming

Some models of object recognition propose that items from structurally crowded categories (e.g., living things) permit faster access to superordinate semantic information than structurally dissimilar categories (e.g., nonliving things), but slower access to individual object information when naming items. We present four experiments that utilize the same matched stimuli: two examine superordinate categorization and two examine picture naming. Experiments 1 and 2 required participants to sort pictures into their appropriate superordinate categories and both revealed faster categorization for living than nonliving things. Nonetheless, the living thing superiority disappeared when the atypical categories of body parts and musical instruments were excluded. Experiment 3 examined naming latency and found no difference between living and nonliving things. This finding was replicated in Experiment 4 where the same items were presented in different formats (e.g., color and line-drawn versions). Taken as a whole, these experiments show that the ease with which people categorize items maps strongly onto the ease with which they name them.     

Wholes and Parts: The Limits of Composition

Abstract

The paper argues that very different part-whole relations hold between different kinds of entities. While these relations share most of their formal properties, they need not share all of them. Nor need other mereological principles be true of all kinds of part-whole pairs. In particular, it is argued that the principle of unrestricted composition, that any two or more entities have a mereological sum, while true of sets and propositions, is false of things and events.     

A scaling method for priorities in hierarchical structures

The purpose of this paper is to investigate a method of scaling ratios using the principal eigenvector of a positive pairwise comparison matrix. Consistency of the matrix data is defined and measured by an expression involving the average of the nonprincipal eigenvalues. We show that λ_max = n is a necessary and sufficient condition for consistency. We also show that twice this measure is the variance in judgmental errors. A scale of numbers from 1 to 9 is introduced together with a discussion of how it compares with other scales. To illustrate the theory, it is then applied to some examples for which the answer is known, offering the opportunity for validating the approach. The discussion is then extended to multiple criterion decision making by formally introducing the notion of a hierarchy, investigating some properties of hierarchies, and applying the eigenvalue approach to scaling complex problems structured hierarchically to obtain a unidimensional composite vector for scaling the elements falling in any single level of the hierarchy. A brief discussion is also included regarding how the hierarchy serves as a useful tool for decomposing a large-scale problem, in order to make measurement possible despite the now-classical observation that the mind is limited to 7 ± 2 factors for simultaneous comparison.     

Lexical Inheritance with Meronymic Relationships

In most computational ontologies, information inheritance is based on the taxonomic relation is_a. A given type inherits from other type only if the latter subsumes the former. We assume, however, that inheritance can be related, not only to the taxonomic relation, but also to the meronymic relationship between parts and wholes. The main aim of this paper is to organise upper-level ontologies associated with lexical information by taking into account part-whole subsumption. As we consider that parts may subsume wholes under specific conditions, ontologies can be defined in terms of systems in which wholes inherit information from its parts. In this article, we describe how part-whole subsumption and, then, meronymic inheritance can be used to deal with type mismatch and metonymic interpretation of polysemous nouns. For this purpose, we attempt to merge old assumptions from both formal ontology and lexical semantics into a homogeneous framework.
