Deep structure,cognition and rebirth: Propositions for viability and vitality in human systems

This paper describes systems dynamics related to deep structure and development processes in human systems, to the process of arresting entropy or premature death in these systems and to the relationship between the cognition of deep structure, its outward manifestation and human systems viability and vitality. The paper proposes that inherent forces are present in systems that act to bring about alignment between inner deep structure and a system's manifested outer structures and processes, thereby enhancing viability and vitality. Deep structure is seen as a force toward self‐organization and rebirth.     

Energy,Complexity, and Strategies of Evolution: As Illustrated by Maya Indians of Guatemala

Using free energy rate density (Φ_m) I differentiate two evolutionary strategies common to cosmic, biological, and cultural systems: the horizontal when energy increases proportional to mass, with no increase in complexity; and the vertical when it increases disproportionately to the mass and complexity increases. The vertical process is a continuing increase in complexity such that the system becomes vulnerable to collapse when energy sources fail. This is illustrated by a comparison of four Mayan Indian groups in Guatemala.     

The Structure of Life History: Implications for the Construct Validity of Background Data Scales

Background data measures have proven to be effective predictors of a variety of criteria. Little attention, however, has been given to the substantive princi- ples underlying their application. In this article, we present a model for un- derstanding the structure of differential life history. This model was used subsequently to generate a substantial framework for applying background data measures. These principles were used then to address various issues bear- ing on construct definition, item generation, and performance prediction. It was concluded that systematic application of construct validation principles may do much to enhance the utility of background data scales.

Sense of Humor and Its Relationship to Personality,Scholastic Aptitude,Emotional Maturity,Height, and Weight

Two experiments were performed having in common the use of sucrose concentration and volume as amount of reinforcement variables, and in situations permitting contrast between concentrations. The following conclusions are reached:

1. It is important to distinguish between the case in which separate subjects are exposed to different concentrations or volumes, and the case in which the same subjects receive different concentrations and volumes.

2. A distinction must be drawn between reinforcement contingencies in which force of response is or is not systematically related to concentration received. In nonforce contingent situations, emitted force is inversely related to concentration, when the same subjects are exposed to the different concentrations. In contingent situations, the relationship tends to be direct.

3. Rate and force of response vary inversely with nonforce contingent volume of sucrose reinforcement, when the same subjects are exposed to the different volumes.

4. Regardless of concentration and volume used, and presumably because of within-session satiation effects, there is a general tendency for rate to decline during nonforce contingent sessions.     

Demand Transitions and Sustained Attention

A recent report by the National Research Council (Huey & Wickens, 1993) has identified transitions in task demand as an important dimension for study in vigilance research. This experiment tested the possibility that the effects of such transitions follow a relatively simple psychophysical rule—they are characterized by contrast effects. Transitions in task demand were achieved by shifting subjects from single-task to dual-task monitoring and vice versa. These transitions produced changes in subjects' sensing and decision-making functions that were far more intricate than simple contrast effects. The demand transition issue offers a complex research challenge on both basic and applied levels and warrants further investigation.     

Delay Discounting as a Function of Intrinsic/Extrinsic Religiousness,Religious Fundamentalism,and Regular Church Attendance

Delay discounting occurs when the subjective value of an outcome decreases because its delivery is delayed. Previous research has suggested that the rate at which some, but not all, outcomes are discounted varies as a function of regular church attendance. In the present study, 509 participants completed measures of intrinsic religiousness, extrinsic religiousness, religious fundamentalism, and whether they regularly attended church services. They then completed a delay-discounting task involving five outcomes. Although religiousness was not a significant predictor of discounting for all outcomes, participants scoring high in intrinsic religiousness tended to display less delay discounting than participants scoring low. Likewise, participants scoring high in religious fundamentalism tended to display more delay discounting than participants scoring low. These results partially replicate previous ones in showing that the process of discounting may vary as a function of religiousness. The results also provide some direction for those interested in altering how individuals discount.     

Reflex Responses of Human Lip Muscles to Mechanical Stimulation During Speech

The role played by reflex pathways in the production of movement has been a significant issue for motor control theorists interested in a wide variety of motor behaviors. From studies of locomotion and chewing, it appears that gains in reflex pathways can be altered so that activity in these pathways does not produce destabilizing responses during movement. In speech production, recent experimental evidence has been interpreted to suggest that autogenetic lip reflexes (perioral reflexes) are suppressed during sustained phonation or speech production. The present study was conducted to assess the effects of phonation, direction of movement, and ongoing speech production on reflex responses of lip muscles. The present results suggest, in contrast to earlier work, that this reflex pathway is not suppressed during phonation or speech. However, the response may appear to be suppressed or absent because the amplitude of the observed response depends upon the activation levels of the various muscles of the lower lip and, therefore, indirectly on the nature of the gesture the subject is instructed to produce.     

Commentary: “A Fundamental Polarity in Psychoanalysis: Implications for Personality Development,Psychopathology, and the Therapeutic Process” by Sidney J. Blatt

A commentary on Dr. Sidney J. Blatt's article, “A Fundamental Polarity in Psychoanalysis: Implications for Personality Development, Psycho-pathology, and the Therapeutic Process” is presented by articulating Dr. Blatt's significant contribution to psychoanalysis, developmental and attachment theory, and therapeutic process research. According to Blatt's theory, normal maturation involves a complex reciprocal transaction between two developmental lines throughout the life cycle: (a) the establishment of stable, enduring, mutually satisfying interpersonal relationships and (b) the achievement of a differentiated, stable, and cohesive identity. He has applied this theory to understand both normal and pathological psychological phenomena, the latter resulting from disruptions in these developmental lines, resulting in an overemphasis on relational (anaclitic) or self-definitional (introjective) issues. Further, Dr. Blatt has evaluated his theoretical model through empirical study and demonstrated that relationally oriented and self-definitionally oriented persons have differential responses to psychotherapy. Finally, areas of question and potential for future research are outlined. Specifically, it is argued that although anaclitic and introjective configurations are easy to discuss as distinct types, relevant evidence from attachment theory raises the issue of whether these types may be better conceptualized as dimensions, with different configurations located within two-dimensional space. Further, findings of a group evidencing mixed anaclitic and introjective features raise additional questions about how these configurations relate to one another, and evidence from the attachment literature is used to shed light on this issue.
