Evolution of communication in perfect and imperfect worlds

We extend previous work on cooperation to some related questions regarding the evolution of simple forms of communication. The evolution of cooperation within the iterated Prisoner's Dilemma has been shown to follow different patterns, with significantly different outcomes, depending on whether the features of the model are classically perfect or stochastically imperfect (Axelrod, 1980a,b, 1984, 1985; Axelrod and Hamilton, 1981; Nowak and Sigmund, 1990, 1992; Sigmund, 1993). Our results here show that the same holds for communication. Within a simple model, the evolution of communication seems to require a stochastically imperfect world.     

The Moderating Effect of Machiavellianism on the Psychological Contract Breach–Organizational Identification/Disidentification Relationships

Purpose

We explore whether Machiavellianism—a personality trait which describes the extent to which individuals ignore values and ethical considerations when the ends justify the means—will influence their responses to their employing organizations’ failure to fulfil promised obligations (psychological contracts). Specifically, we draw on psychological contracts theory and the group value model to argue that Machiavellianism will moderate the relationships between psychological contract breach and (1) organizational identification; and (2) organizational disidentification.

Design/Methodology/Approach

We tested our hypotheses in a study of 262 employees from various organizations at two points in time.

Findings

We found that psychological contract breach was negatively related to organizational identification and positively related to organizational disidentification. Furthermore, employees with higher levels of Machiavellianism tended to disidentify with their organizations to a greater extent (at Time 2) in response to psychological contract breach (at Time 1) than did employees with low levels of Machiavellianism. Machiavellianism did not moderate the relationship between psychological contract breach and organizational identification.

Implications

Our study contributes to extant research exploring the importance of Machiavellianism in the workplace. Specifically, we show that employees with high levels of Machiavellianism are more likely to disidentify in response to psychological contract breach but do not tend to identify to a lesser degree.

Originality/Value

This study builds on the extant research exploring individual differences in the psychological contract dynamics by considering Machiavellianism as a moderator of the breach–outcome relationship.     

Psychometric Properties of the Locus of Control of Behaviour Scale (LCBS) among Australians Seeking Alcohol and Other Drug (AOD) Treatment

Despite a paucity of studies evaluating the psychometric properties of the Locus of Control of Behaviour Scale (LCBS), it continues to be widely used in behavioural research. The present study sought to redress this gap in the literature. The 17‐item LCBS was administered to 373 Australians attending Alcohol and Other Drug (AOD) treatment agencies in the northern metropolitan region of Perth. Confirmatory factor analyses were conducted in order to determine which of several plausible measurement models provided the best fit for the data. A unidimensional model, recommended by the authors of the LCBS, and a two‐dimensional (Internal Locus of Control vs External Locus of Control) model provided poor fits. Other multidimensional models, differing only in the dimensionality of the externality factor, were also tested. A multidimensional model consisting of an Internal Locus of Control factor and four component External Locus of Control factors provided the best fit; however, the fit is probably best described as “reasonable” rather than “good.” A subsequent exploratory factor analysis using parallel analysis indicated a cohesive internality factor; however, the externality factor showed a tendency to fragment into smaller components. Results were discussed in terms of the problematic externality factor.     

Good intentions and failed implementations: Understanding culture-based resistance to organizational change

Based on the insight that culture shapes resistance to change in an organization, and the recognition that cultures of organizations are embedded in a broader societal culture, this study seeks to provide empirical evidence on how societal-based cultural understandings and values within an organization serve as a source of resistance to change among employees. The study is based on a case study of a medium-sized Turkish company. The study shows how certain managerial decisions toward a professionally running organizational design are difficult to implement due to societal-based patterns of understandings and meaning systems gathered around status, hierarchy, and emotion-based (personalized) relations in the company.     

Intimate partner violence: A narrative review of the biological and psychological explanations for its causation

Intimate partner violence (IPV) is a major social and public health problem that affects men and women across the globe regardless of their culture, religion and other demographic characteristics. During the last 100 years many different theories have been proposed to explain the phenomenon of IPV. Much research is been conducted using these theories as a guiding or underlying framework. However, it is difficult to find a single account that provides a succinct and up-to-date overview of these theories. As a result considerable effort is required to identify and retrieve relevant papers to understand the various theories which attempt to explain IPV. This article attempts to provide a succinct and up-to-date integrative review of the biological and psychological explanations of IPV. Both perspectives have been critically evaluated in the light of the available literature and an attempt has been made to discuss the strengths and limitations of each perspective in shedding light on the causation of IPV.     

Strategies adopted by Turkish adults for increasing happiness in daily life

The present study aims to focus on the strategies adopted by adults in seeking ways to increase happiness in their daily life and to determine whether or not significant differences exist between happiness levels in adults at the very beginning and the end of a four-month period. Sixty-eight adults who were found eligible were included in this study. The research method is of a mixed type. The distinguishing feature of this study is the experience sampling method employed. Positive–Negative Affect and Satisfaction with Life Scales, an experience sampling data form and a personal information form were used in the study. The study results show that adults adopt various strategies in order to get rid of their unhappiness and increase their happiness in three contexts. No statistical significance could be determined between the measurements achieved at the beginning and at the end of the study into the happiness of the participants.     

Spatial distinctiveness effect in categorisation

The aim of the present study was to show that the probability of an item being retrieved is proportional to its spatial distinctiveness, and that this distinctiveness effect can be obtained in an implicit memory task. The participants were presented with two phases in which they had to categorise pictures of objects as either “kitchen utensils” or “do-it-yourself tools”. In our encoding phase, the pictures were successively presented in different positions on the screen. The positions were arranged in one of two different configurations: a “distinctive condition” in which the pictures were placed in two circles, one central and one peripheral, such that the distance between the pictures was greater when they were in a peripheral position than in a central position, and a “nondistinctive” condition, in which the distance between the pictures was constant irrespective of their central or peripheral position. In the test phase, the same pictures were presented for categorisation, mixed with new pictures at the centre of the screen. The results clearly confirmed our expectations.     

Probability matching: encouraging optimal responding in humans.

Two hundred undergraduate students participated in a repeated-trials binary choice procedure in which choice of one outcome was correct on 75% of trials. Subjects received 192 trials and were divided into five conditions: (1) control; (2) subjects were given the actual probabilities; (3) subjects were told if they did well they could leave early; (4) competition condition; (5) midway through the task subjects were asked to recommend a strategy for another subject. Half of the subjects in each group were told that the best they could do was to be correct on 75% of the trials. This manipulation permitted assessment of the hypothesis that subjects in probability-matching tasks are seeking a strategy that will be correct on 100% of the trials. The results partially confirmed this hypothesis. In addition, two of the variables improved performance significantly (giving probabilities and asking subjects to recommend a strategy). However, while subjects in all groups improved significantly over trials, optimal choice did not occur in this task.
