Children by choice or by chance: The perceived effects of parity

In a study examining inferences made about couples based on their choice whether or not to have children, college undergraduates projected 1-year and 25-year life situations for a hypothetical couple who either (1) neither had nor wished to have children, (2) were presented without any reference to children, or (3) already had two children. This manipulation notwithstanding, most couples were projected as becoming parents. Female subjects saw having children as enhancing the quality of life of both partners, while males took the opposite view.     

The effects of representations and behavior in experimental games

This research shows that in an experimental game it is the perception of an actual relationship, of an interaction with the other person more than the nature of the game which creates a climate in which cooperative responses can be established. Cooperative sets can be induced through the Representation of the partner: a reactive partner promoting cooperation, and a rigid one promoting competition. In addition it is noted that in order to understand the reactions induced by the partner's behavior, the behavior in itself it not sufficient. Indeed it is interpreted and understood in terms of the initial representation. The analysis of a person's behavior when in relation with another, should be based on a joint study of the existing representations and of the actual behavior observed.     

Quota vs positional power in four-person apex games

In coalition formation experiments, which coalitions will form and how players in coalitions will allocate their jointly gained rewards are typically predicted as a function of the players' relative power. In this paper, we isolated two logically independent sources of a player's power: the player's contribution to the rewards obtainable by coalitions of which he may be a member (“quota power”), and the number of distinct coalitions which a player may join (“positional power”). The separation of the two types of power is clearly shown in apex games, where a single player (Apex) attempts to lure any of the other players (Base) from the coalition of all Bases. A series of four-person computer-controlled apex and nonapex characteristic function games, varying with respect to the relationship of quota power to positional power, were played by 15 quartets of male players. Quota power was strongly manifested in all outcome measures, while positional power appeared only as a bias toward equal allocations of reward when coalitions among players of equal positional power formed. Neither of two social psychological theories that are applicable, pivotal power and weighted probability theory, predicted coalition frequencies. In a test of five solution concepts, the competitive bargaining set predicted payoff allocations better than either of the two aforementioned theories, the kernel, or an equal-split model.     

Discriminating memories for actual and imagined taste experiences: a reality monitoring approach

Blindfolded subjects tasted 4 common fruits and imagined the taste of 4 others while focusing on either a few (low sensory detail [SD] or many (high SD) of the fruit's sensory qualities. One week later, subjects judged whether each of 12 fruit names represented a fruit that was previously tasted, imagined tasted, or new (reality monitoring). The major finding was a significant interaction between source (imagined, perceived) and SD level (low, high). Source monitoring was accurate for imagined and perceived fruits in the low SD condition and for perceived fruits in the high SD condition. As predicted, subjects tended to misattribute memories for imagined fruits to perception in the high SD condition. The findings are discussed with reference to the Johnson-Raye reality monitoring model and recent work on memory source confusions.     

Holistic processing improves change detection but impairs change identification

It has been just over a century since Gestalt psychologists described the factors that contribute to the holistic processing of visually presented stimuli. Recent research indicates that holistic processing may come at a cost; specifically, the perception of holistic forms may reduce the visibility of constituent parts. In the present experiment, we examined change detection and change identification accuracy with Kanizsa rectangle patterns that were arranged to either form a Gestalt whole or not. Results from an experiment with 62 participants support this trade-off in processing holistic forms. Holistic processing improved the detection of change but obstructed its identification. Results are discussed in terms of both their theoretical significance and their application in areas ranging from baggage screening and the detection of changes in radiological images to the systems that are used to generate composite images of perpetrators on the basis of eyewitness reports.     

Multiply-divorced job hoppers presenting as psychiatric patients

Six cases are described of multiply-divorced job hoppers presenting as psychiatric patients. Following a finding by Vaillant and Milofsky (1980) in their study of the life cycle of inner-city males, a relationship is suggested in the sample of six between marital and job instability. While the six showed a capacity for the intimacy of marriage and the demands of work, they showed an inability to persevere in these demanding relationships. It is speculated that their failure to persevere in difficult, demanding relationships placed them at special risk to become psychiatric casualties.     

Proposal for a Distinctive Diagnosis: the Deliberate Self-Harm Syndrome (DSH)

ABSTRACT: Self-destructive behavior is a major clinical problem in psychiatry. A review of the literature reveals the existence of enough clinical data to identify a diagnostic entity, “The Deliberate Self-Harm Syndrome” (DSH). The authors present a diagnostic formulation of the DSH syndrome (in the DSM-III format) which consists of four essential clinical features, a group bof associteds features, clinical features, a group of associated features, a clinical course of typical onset in late adolescence, with multiple recurent episodes, with multiple methods of low lethality physical self-injury, extending over many years. On the basis of relatively exclusive association of clinical signs and symptoms a heuristic clinical entity is proposed.
