Crowding effects of density and personal space requirements among older people: the impact of self-control and social support

The authors examined the effects of self-control and social support among a representative sample of 300 older people, 150 in high-density and 150 in low-density households in India. The Self-Control Schedule (M. Rosenbaum, 1980), the Comfortable Interpersonal Distance Test (M. Duke & S. Nowicki, 1972), the Social Support Questionnaire, and the Judgement of Environmental Quality Scale (I. G. Sarason, H. M. Levine, R. B. Basham, & B. R. Sarason, 1983) were the measures. A 2 x 2 x 2 (Density x Social Support x Self-Control) analysis of variance for perceptions of home environment and personal space requirements revealed that the Self-Control x Social Support interaction moderated the crowding effects of density: The participants in high-density households evaluated their home environments more positively and reduced their personal space requirements.     

Crowding and stress: 1. Review of variables and theories

Recent empirical research has sometimes failed to support the existence of a direct causal link between human crowding, as measured by objective density indices, and stress effects. It has even been proposed that high density merely intensifies reactions due to other causes, thereby casting basic doubt on the reality of crowding-induced stress. Conceptual issues in crowding research are discussed, and an attempt is made to resolve definitional problems. Theories of crowding are reviewed, suggesting that any plausible theory of crowding effects must take seriously the cognitive mediation of environmental variables, plus the operation of a complex set of personal and interpersonal processes which will determine whether and when high densityis likely to result in stress. These considerations cast doubt on the generalizability of that research which has failed to demonstrate crowding stress effects, and highlight the need for an integration of existing theories, so that predictions of the circumstances where crowding stress is most likely can eventually be made with greater precision.     

Assaultive behavior personality and personal space

Eysenck's Psychoticism, Extraversion and Neuroticism (PEN) Inventory was used to explore the role of personality variables in augmented personal space required by assaultive offenders. For both violent (n = 20) and nonviolent (n = 20) subjects personal space was greatest from a rear approach. Neither personality scores nor nature of offense alone predicted personal space needs; however personal space was significantly elevated in all directions for assaultive offenders with high scores on the psychoticism scale of the PEN Inventory.     

Post-traumatic stress disorder: A congnitive-contextural approach

Most people are psychologically effected by an extreme trauma and for a significant minority the debility is long term, often expressed as post-traumatic stress disorder (PTSD). A cognitive-contextual approach is described in which the prime focus is upon teaching the client how to interact adaptively with the memory of the trauma by: a) facilitating a switch from a primarily perceptual to a more conceptual level of processing the trauma itself; and b) placing the trauma in the context of past life experiences and determining its relevance for the future. The approach is illustrated by the treatment of a PTSD diagnosed motor vehicle accident victim.     

Body-image, personal space, and self-esteem: a field study

In an earlier study, the author reported changes in body boundary perception and interaction distance resulting from the experimental manipulation of self-esteem. The present study attempted to replicate these laboratory findings in a field setting. The test battery included a self-esteem questionnaire and was administered to Army recruits before and after participation in a leadership training course. Results showed that while self-esteem had been modified predictably by performance, interaction distance was only partially affected, and the boundary indices remained unchanged. Results were discussed in relation to immediacy effects on the evaluation of competence, and their implications for field as compared to laboratory research.     

Perceptions of personal Web usage in the workplace: AQ-methodology approach.

An important aspect to managing Personal Web Usage (PWU) at the workplace lies in understanding and reshaping the perceptions of the users. The study contends that the outward manifestation of PWU behaviors at the workplace is but one consequence of the actors' attitudes which in turn are determinants of their ingrained beliefs. This study explores user perceptions about PWU using a web-based Q-methodology. Q-methodology used in this study is suitable for exploratory research, to obtain a deeper and first-hand understanding about the underlying phenomena about an under-explored concept. Twenty-five participants were asked to sort 38 statements according to their relative importance. The results uncover three distinct factors PWU: (1) cyber-bureaucrat, (2) cyber-humanist, and (3) cyber-adventurer. This indicates that PWU maybe a multidimensional construct instead of a uni-dimensional one as previously thought. The findings of this study can help managers understand, and shape the perceptions of the users rather than the outwardly manifested behaviors.     

Statistical manifold as an affine space: A functional equation approach

A statistical manifold M_μ consists of positive functions f such that defines a probability measure. In order to define an atlas on the manifold, it is viewed as an affine space associated with a subspace of the Orlicz space L^Φ. This leads to a functional equation whose solution, after imposing the linearity constrain in line with the vector space assumption, gives rise to a general form of mappings between the affine probability manifold and the vector (Orlicz) space. These results generalize the exponential statistical manifold and clarify some foundational issues in non-parametric information geometry.     

A new argument for the phenomenal approach to personal persistence

Philosophical Studies - When it comes to personal identity, two approaches have long ruled the roost. The first is the psychological approach, which has it that our persistence through time...     

A person-centred approach to stress management

Stress is analysed from a phenomenological perspective in terms of how individuals evaluate the varying stressors in their lives. The basic philosophical tenets underlying the person-centred approach to therapy are outlined with its emphasis on the ability of the individual human organisms to heal and recover from dysfunction.     

A hierarchical state space approach to affective dynamics

Linear dynamical system theory is a broad theoretical framework that has been applied in various research areas such as engineering, econometrics and recently in psychology. It quantifies the relations between observed inputs and outputs that are connected through a set of latent state variables. State space models are used to investigate the dynamical properties of these latent quantities. These models are especially of interest in the study of emotion dynamics, with the system representing the evolving emotion components of an individual. However, for simultaneous modeling of individual and population differences, a hierarchical extension of the basic state space model is necessary. Therefore, we introduce a Bayesian hierarchical model with random effects for the system parameters. Further, we apply our model to data that were collected using the Oregon adolescent interaction task: 66 normal and 67 depressed adolescents engaged in a conflict-oriented interaction with their parents and second-to-second physiological and behavioral measures were obtained. System parameters in normal and depressed adolescents were compared, which led to interesting discussions in the light of findings in recent literature on the links between cardiovascular processes, emotion dynamics and depression. We illustrate that our approach is flexible and general: The model can be applied to any time series for multiple systems (where a system can represent any entity) and moreover, one is free to focus on various components of this versatile model.     

Crowding effects of density and interpersonal distance.

In this study, Turkish teenagers were the subjects in an investigation of the effects of spatial and social variables on perceived crowding. In Study 1, male and female subjects were presented with diagrams that simulated social situations in which (a) distance between the subject and other persons, (b) number, or density, of subjects, (c) sex, and (d) friendship were systematically varied. Results indicated a significant crowding effect for interpersonal distance but not for density. In Study 2, data from Turkish college students showed that the lack of effect for density on crowding was stable. Friendship and sex of others had significant main and interaction effects.     

Examining business students' career preferences: A perceptual space approach

A methodology for examining career preferences is proposed. The method uses perceptual mapping techniques and external preference analysis to assess the attributes individuals believe are important. The results of a study undertaken to test the methodology are reported and it appears that such results can be useful in analyzing reasons for career preferences.
