Modelling simultaneous games in dynamic logic

We make a proposal for formalizing simultaneous games at the abstraction level of player’s powers, combining ideas from dynamic logic of sequential games and concurrent dynamic logic. We prove completeness for a new system of ‘concurrent game logic’ CDGL with respect to finite non-determined games. We also show how this system raises new mathematical issues, and throws light on branching quantifiers and independence-friendly evaluation games for first-order logic.     

Similarity based approximate reasoning: fuzzy control

This paper presents an approach to similarity based approximate reasoning that elucidates the connection between similarity and existing approaches to inference in approximate reasoning methodology. A set of axioms is proposed to get a reasonable measure of similarity between two fuzzy sets. The similarity between the fact(s) and the antecedent of a rule is used to modify the relation between the antecedent and the consequent of the rule. An inference is drawn using the well-known projection operation on the domain of the consequent. Zadeh's compositional rule of inference and existing similarity based reasoning techniques are considered for a new similarity based approximate reasoning technique. The proposed mechanism is used to develop a modified fuzzy control system. A new defuzzification scheme is proposed. Simulation results are presented for the well-known inverted pendulum problem.     

Life events stress and chronic pain

Stress in life has been found to play a role in triggering, maintaining and exacerbating chronic pain, yet, direct empirical evidence of the mechanism of such a role is limited. In the present study 120 non-selected chronic pain patients and an equal number of matched healthy normals were investigated with regard to life events stress. The investigation revealed that although, patients and controls did not differ in terms of number of events experienced during the last 1 year, however, patients reported significantly higher frequency of occurrence on a distinctive set of events belonging to personal, interpersonal and familial life and events related to change in eating and sleeping habits. Our results emphasize the importance of studying the life events beyond the simple count of number of event occurrence but to explore the specific events those cluster around pain disorders.     

Nonstrategic Delay in Bargaining: An Experimental Investigation

The practice of bargaining is strongly affected by procedural features. Procedures matter because they affect each party's bargaining power and, consequently, the negotiation outcome. The extent and nature of delay between offers and counteroffers are an example of procedural specification in bargaining. Bargaining models consider delay only as a strategic screening device to build a reputation for toughness, the logic being that the party with the smaller cost of delay obtains all the gain from trade. In reality, however, delay between offers is common because of imperfect player control over the duration of the offers for reasons other than strategic, namely, transactional, timing, and interruptions. This delay, in essence, limits the number of rounds of offers and counteroffers in a fixed-period negotiation compared to when there is no delay and, in turn, is expected to affect negotiation outcome. The objective of the current research is to experimentally explore the implications of nonstrategic delay between offers and counteroffers in a finite-horizon alternating-offer bargaining game with incomplete information but without discounting. Specifically, this study examines the effect of nonstrategic time delay during negotiation on (1) the effect of risk preference on negotiator effectiveness, (2) deadline effect, (3) first-mover advantage, and (4) conflict between the negotiating partners. As hypothesized, the results show that delay dilutes the effect of negotiators’ risk preference, eliminates the deadline effect, negates the first-mover advantage, and enhances dyadic conflict.     

Positive Psychology Interventions for Chronic Physical Illnesses: A Systematic Review

Positive health focuses on enhancing health along with curing illness to bring about well-being. Treatment for physical illness generally involves drug therapy, while the psycho-social aspects, specifically the positive psychology perspectives, are largely ignored; nevertheless, a growing number of investigations are now studying the effects of positive psychology interventions on health outcomes. The objective of this paper is to systematically review positive psychology interventions in chronic physical illness. A literature search through the databases of EBSCO, PubMed and PsycINFO, reference lists of significant papers and grey literature was conducted following four criteria set for this review. The number of studies selected finally that acceded to the criteria was 14. These studies were analysed by focusing on the study characteristics, kinds of intervention and outcomes of positive psychology interventions. Overall findings reveal that different intervention programmes have been devised by combining various exercises, writing is the most commonly used method for administration and positive psychology interventions are considered feasible and acceptable by patients, but findings about their usefulness are inconclusive. Suggestions for future research, clinical practice and application in communities have been provided which may be useful for clinicians, practitioners and caregivers.     

A Process Analysis of the Effects of Humorous Advertising Executions on Brand Claims Memory

We report 2 studies that examined how the strength of humorous advertising executions and their relevance to the brand claims in the advertisement influence consumer memory for the claims. We infer the underlying memory processes by testing claims memory using recall, recognition, and indirect tests following incidental exposure to advertisements manipulating humor strength and claims relevance. Memory for the humor component was checked as corroborating evidence. We also validated these inferences by contrasting these effects on claims and humor memory with those under instructed elaboration. Study 1 shows that for humor of low claims relevance, brand claims memory is an inverted U‐shaped function of humor strength. Compared to both nonhumor and high‐strength humor, moderate humor facilitates both encoding and retrieval of the claims. The patterns of humor memory and instructed elaboration effects suggest that low‐relevance humor is not spontaneously linked to the claims even when processing resources are available. Study 2 shows that when strong humor is made more relevant, brand claims memory improves even during incidental exposure. Corresponding humor memory and instructed elaboration effects imply that relevance encourages the formation of humor‐claims links that facilitate encoding and retrieval of the claims. The results show that although strong humor inhibits the processing received by the brand claims, enhancing its claims relevance can compensate for such inhibition.

Introspection and Primacy of Perception: A Critical Reflection on Naïve Realism

A fundamental issue in philosophy of perception is to understand the nature of experience and the relation of the experience with objects or states of affairs that is experienced. A prominent philosophical issue here is posed by the possibility of hallucinatory experiences, which are subjectively indistinguishable from veridical perception for the experiencer. The philosophical views in this matter can be grouped into three major positions on the basis of the nature of the subjective experience and relation of the subjective experience with the object. These are the sense-data theories—which consider that the objects of perception are mental entities; the representative theories—according to which perception is a representation of the objects in the external world; and the naïve realist theories—which proclaim that the external objects are constitutive of the very perceptual experience and not a representation of it. Naïve realism claims it is the defence of common-sense notion regarding experience i.e. how experience seems to the experiencer upon introspective reflection on it. This position has a growing number of proponents in philosophy especially in the last two decades. But it also entails radical departure of established philosophical views regarding the nature of experience, the phenomenal character of experience, and the experiencer–object relation. In this paper, we critically examine naïve realism from two crucial aspects pertaining to it—the question of introspection being basis of naïve realist thesis, and the notion of primacy of perception over non-veridical forms of experiences. We find that there are significant problems which weaken the naïve realist thesis.

     

Voices Unheard: The Psychology of Consumption in Poverty and Development

Many facets of contemporary global problems posed by poverty pertain to the deprivation of consumption capability and are within the consumer psychologist's expertise domain. This article (based on my 2004 Presidential Address to the Society for Consumer Psychology [SCP]) outlines how consumer psychology research can contribute an understanding of the cognitive, motivational, and sociocultural dimensions of poverty, and how poverty depletes and alters the human need and capacity to consume. Consumer psychology research can also help suggest the nature and function of material and psychological interventions that can help ameliorate these conditions, focusing their design and monitoring their effects. These are important research priorities for consumer psychologists and deserve more and sustained attention from our community. Apart from garnering voice in policy conversations in government, industry, and academe, such research eventually will enhance our field's substantive contribution to improving the contemporary human condition.
