The role of representation in computation

Reformers urge that representation no longer earns its explanatory keep in cognitive science, and that it is time to discard this troublesome concept. In contrast, we hold that without representation cognitive science is utterly bereft of tools for explaining natural intelligence. In order to defend the latter position, we focus on the explanatory role of representation in computation. We examine how the methods of digital and analog computation are used to model a relatively simple target system, and show that representation plays an in-eliminable explanatory role in both cases. We conclude that, to the extent that biologic systems engage in computation, representation is destined to play an explanatory role in cognitive science.

RELIGIOUS REASONS AND POLITICAL ARGUMENTATION

In Evangelium Vitae Pope John Paul II calls for a renewal of culture to combat the culture of death. He criticizes various aspects of a pluralistic, liberal society—a type of society that he claims is based on moral relativism and a view of democracy that becomes a substitute for moral law. He maintains that such a view trivializes moral choice. In this essay I argue that John Rawls's notion of a liberal society as an overlapping consensus of comprehensive doctrines can avoid relativism while allowing for reasonable debate among opposed positions. While Rawls maintains that comprehensive doctrines, including religions, should employ a form of public reason that is not a unique feature of any one comprehensive doctrine, I argue that this requirement is too strong. One is often justified in appealing to features of comprehensive doctrines other than one's own, features that are unique to the doctrines themselves. Such an appeal does not pretend to be neutral as public reason would seem to be. In the final section of the paper I discuss some suggestions made by the Pope regarding actions in civil society that are independent of debates about legal change and suggest some ways in which they might contribute to desired cultural transformation.     

A multiple option observation system for experimental studies: MOOSES

The purpose of this article is to outline the development of the Multiple Option Observation System for Experimental Studies (MOOSES), a flexible data collection package for applied behavioral research. Several data collection options are available to users of MOOSES. Event-based recording, interaction-based recording, duration recording, and interval recording are available to the users and can be used individually or together, depending upon the research question. The collection program can incorporate any of the keys on the keyboard. Function keys on the top or side are used for toggle (duration states) type data collection. Types of analysis include frequency and duration of discrete events, frequency of general behavior states, frequency and duration of events within behavioral states, percent interval analysis, sequential analysis, and interobserver agreement. Data obtained from MOOSES is easily incorporated with other data for further statistical analysis with standard statistical packages or popular spreadsheet programs. Applications of MOOSES and its uses in social interaction research are presented. Comparisons with other similar systems are provided.     

PRIMING FROM THE ATTENTIONAL BLINK:

Abstract —When people must detect several targets in a very rapid stream of successive visual events at the same location, detection of an initial target induces misses for subsequent targets within a brief period. This attentional blink may serve to prevent interruption of ongoing target processing by temporarily suppressing vision for subsequent stimuli. We examined the level at which the internal blink operates, specifically, whether it prevents early visual processing or prevents quite substantial processing from reaching awareness. Our data support the latter view. We observed priming from missed letter targets, benefiting detection of a subsequent target with the same identity but a different case. In a second study, we observed semantic priming from word targets that were missed during the blink. These results demonstrate that attentional gating within the blink operates only after substantial stimulus processing has already taken place. The results are discussed in terms of two forms of visual representation, namely, types and tokens.     

BEHAVIORAL SCHOOL PSYCHOLOGY GOES OUTDOORS: THE EFFECT OF ORGANIZED GAMES ON PLAYGOUND AGGRESSION

This research focuses on the inappropriate, largely aggressive, behaviors of 344 K-2 children assigned to a playground prior to the beginning of the school day. Initially, a system for observing large numbers of children freely roaming over a large, open area was developed. This observational method was then used to determine the effectiveness of providing organized games for reducing potentially dangerous playground behaviors. Using a reversal (ABAB) design, it was found that the games, rope jumping, and foot racing, along with an infrequently used time-out procedure, significantly reduced the frequency of inappropriate incidents. It is suggested that when dealing with large groups, antecedent environmental manipulations may be more practical than providing consequences for the behaviors exhibited by identified individuals.     

Patriarchy and phantasy: A conception of psychoanalytic sociology

The nature versus nurture controversy in the history of the social sciences is compared with the heredity versus environment debate in the history of psychoanalysis. Generally, psychoanalysis addresses the question of human thought in contrast to the social disciplines, which examine human behavior. This division of science may be considered the representation of a fundamental dichotomy between internal (latent) and external (manifest) aspects characteristic of human existence. This universal duality is based on the division between the sexes, the union of which reproduces life. This paper attempts to draw attention to the common structure of the mind and society by showing that the same pattern of manifest and latent content exists within each entity. The manifest aspect of existence is reflected in patriarchal social structure and the latent aspect in the structure of unconscious phantasy. These aspects are dialectically interrelated in that patriarchy is the manifest form of phantasy and phantasy the latent form of patriarchal order. This model of the integration of psychoanalysis and sociology is based on the work of Juliet Mitchell, particularly Psychoanalysis and Feminism. Psychoanalytic sociology is defined as a discipline that investigates the relationship between mental life and social organization.     

TREATING OVERWEIGHT CHILDREN THROUGH PARENTAL TRAINING AND CONTINGENCY CONTRACTING1

Fifteen overweight girls aged 5 to 11 yr were randomly assigned to one of two weight-reduction treatments: response-cost plus reinforcement, response-cost only, or a no-treatment control group. In the response-cost plus reinforcement group, parents contracted to facilitate their child's weight loss by carrying out reinforcement and stimulus control techniques, completing weekly charts and graphs, and encouraging their child to exercise. The response-cost only group parents did not contract to reinforce their child's performance. The response-cost program applied to both experimental groups was conducted in weekly meetings in which parents lost previously deposited sums of money. Twenty-five per cent was deducted for missing the weekly meeting, 25% for failing to fill out charts and graphs, and 50% if their child failed to meet her specified weekly weight-loss goal. At the end of the 12-week treatment period, both experimental groups had lost significantly more weight than the control group. After an eight-week, no-contact follow-up, some of the lost weight was regained. The response-cost plus reinforcement group was still significantly below the controls. The response-cost group just missed significance. A 31-week, no-contact follow-up failed to show a treatment effect, but did show a trend towards slower weight gain by the response-cost plus reinforcement group.
