Perceptual projects:A theory of veridicality and distortion in perception

Abstract.— The split between objective and subjective information, characterizing dualistic theories of perception, is argued to have caused contradictions around the problems of veridicality of perception and the attention-attracting power of stimulus properties. The theory of threshold-regulation in categorical perception is criticized and an alternative model is suggested, where the main distinctions are between the "knowing how" and the "knowing that" of perception, between exteriorization and interiorization, and between the perceptual project and the perceptual foundation. It is demonstrated that concepts used in the analysis of dialogical communication are useful in the theory of perception to explain phenomena such as curiosity, boredom, and pathological perception.     

The Phenomenology of erwin Straus: An overview and appraisal of its relevance for human studies

Abstract

The purpose of this paper is to discuss the veridicality of nonconventional cognitions as they pertain to transpersonal psychological inquiry. It is argued that the validation and efficacy of transpersonal constructs are dependent upon the manner by which they are theoretically and empirically supported, namely, accurately conceptualized and operationalized, and not metaphysicalized. Salient impediments germane to the study of transpersonal phenomena are also reviewed with the concomitant assumption that their ontological and epistemological status should be consistent with objective, nomothetic, empiricism. In response to this scientific appropriation, one measurement instrument is discussed, the Self‐Expansiveness Level Form (SELF; Friedman, 1981; 1983), which is both reliable and valid in measuring transpersonal‐like phenomenon. Taking into consideration these notions, this paper closes with a discussion on the implications of this measurement scale to the field of transpersonal psychology as well as to conventional psychological research and clinical applications.     

Bayesian confusions surrounding simplicity and likelihood in perceptual organization

In the study of perceptual organization, the Occamian simplicity principle (which promotes efficiency) and the Helmholtzian likelihood principle (which promotes veridicality) have been claimed to be equivalent. Proposed models of these principles may well yield similar outcomes (especially in everyday situations), but as argued here, claims that the principles are equivalent confused subjective probabilities (which are used in Bayesian models of the Occamian simplicity principle) and objective probabilities (which are needed in Bayesian models of the Helmholtzian likelihood principle). Furthermore, Occamian counterparts of Bayesian priors and conditionals have led to another confusion, which seems to have been triggered by a dual role of regularity in perception. This confusion is discussed by contrasting complete and incomplete Occamian approaches to perceptual organization.     

Self-Ratings and Projected Ratings of Sex Role Attitudes

To ascertain the veridicality of projected attitudes toward sex role behavior, 74 male and 74 female undergraduates filled out the Attitudes Toward Women Scale (AWS) using three different targets: self, typical female classmate, and typical male classmate. Analyses of variance on respondents' total AWS scores and on the six AWS subscale scores showed significant interactions between sex of respondent and sex of target for all seven variables. Since the directions of the interactions were not consistent across subscales, the results indicated the methodological necessity of using measurements which examine a variety of specific subclasses of sex role behaviors (rather than using unidimensional scale or total test scores) when stereotypic sex role attitudes are sought. In general, both sexes were found to have a fairly accurate perception of women's attitudes, but both sexes consistently perceived the typical male as more conservative than the male self-ratings justified.     

Energy Conservation: Two Easy Ways Out1

This study investigated attitude-behavior relationships in the context of energy conservation. Results indicated that general environmental concern is a poor predictor of energy-conservation behaviors. Direct evaluative comparisions of various non-conservationist behaviors with a more conservationist alternative showed a clear relationship with behavioral preference. Non-conservationists, however, evaluated their own behavior only marginally favorably and in some cases clearly unfavorably. This was accompanied by an overestimation of the common occurrence of these behaviors among the general population and by an unwillingness to relate these behaviors to personality characteristics. It is argued that these biases (i.e., considering one's behavior as a habit that is shared by many others) could hinder behavioral change. These findings are discussed in terms of effective public policy on the issue of energy consumption.     

Dissociating veridicality, consistency, and confidence in autobiographical and event memories for the Columbia shuttle disaster

A total of 449 students were tested for their event memories and autobiographical memories of hearing about the Columbia shuttle disaster of 1st February 2003. Four different groups were tested 2, 18, 27, or 51 days after the event. All participants were then re-tested after 5 months (second session) and again after 1 year (third session) from the first interview. Dissociations between consistency and confidence and between event and autobiographical memories were found. Consistency and confidence in event memories, but not in autobiographical memories, were affected by time. In contrast, repeated testing selectively enhanced autobiographical memories, in accordance with the narrative and rehearsal hypothesis of Neisser and Harsh (1992). For event memories, veridicality was inversely correlated to consistency, which in turn was inversely correlated to confidence, and mainly based on omissions. As regards veridicality, the analyses showed an increase of false memories at long time delays. Results are discussed with reference to recent studies contrasting autobiographical and event memories.

Beyond the purely cognitive: Belief systems,social cognitions,and metacognitions as driving forces in intellectual performance

This study explores the way that belief systems, interactions with social or experimental environments, and skills at the “control” level in decision-making shape people's behavior as they solve problems. It is argued that problem-solvers' beliefs (not necessarily consciously held) about what is useful in mathematics may determine the set of “cognitive resources” at their disposal as they do mathematics. Such beliefs may, for example, render inaccessible to them large bodies of information that are stored in long-term memory and that are easily retrieved in other circumstances. In other cases, individuals' reactions to an experimental setting (fear of failure, or the desire to “look mathematical” while being videotaped) may induce behavior that is almost pathological—and at the same time, so consistent that it can be modeled. In general, such “environmental” factors establish the context within which individuals access and utilize the information potentially at their disposal. Protocols illustrating these points are presented and discussed. A model based on an axiomatization of students' beliefs about plane geometry is outlined, and is shown to correspond closely to their problem-solving performance. A framework is offered for analyzing problem-solving performance at three qualitatively different levels: access to cognitive resources stored in LTM, executive or control decision-making, and belief systems.     

Understanding Executive Control in Autism Spectrum Disorders in the Lab and in the Real World

In this paper, we review the most recent and often conflicting findings on conventional measures of executive control in autism spectrum disorders. We discuss the obstacles to accurate measurement of executive control, such as: its prolonged developmental trajectory; lack of consensus on its definition and whether it is a unitary construct; the inherent complexity of executive control; and the difficulty measuring executive-control functions in laboratory or clinical settings. We review the potential of an ecological-validity framework to address some of these problems, and describe new tests claiming verisimilitude, or close resemblance to “real life” demands. We also review the concept of veridicality, which allows for the measurement of the ecological validity of any task, and discuss the few studies addressing ecological validity in individuals with autism. Our review suggests that a multi-source approach emphasizing veridicality may provide the most comprehensive assessment of executive control in autism.     

Current behavior modification in the classroom: be still, be quiet, be docile

Classrooms have recently been criticized as total institutions where there is a rigid preoccupation with order and control, and where children are required to be still, to be silent, and to obey. Behavior modification has been described as a major source of change in the classroom. A review of this journal's papers on behavior modification in the classroom indicated that inappropriate behavior has been consistently defined as behavior that interferes with order, quiet, and stillness. It is argued therefore, that behavior modification has supported rather than changed the questionable status quo. Alternative areas for behavior modification in traditional classrooms and the role of behavior modification in the development of open classrooms are discussed.     

Proof-Theoretic Semantics, Self-Contradiction, and the Format of Deductive Reasoning

From the point of view of proof-theoretic semantics, it is argued that the sequent calculus with introduction rules on the assertion and on the assumption side represents deductive reasoning more appropriately than natural deduction. In taking consequence to be conceptually prior to truth, it can cope with non-well-founded phenomena such as contradictory reasoning. The fact that, in its typed variant, the sequent calculus has an explicit and separable substitution schema in form of the cut rule, is seen as a crucial advantage over natural deduction, where substitution is built into the general framework.     

Continuously varying binocular disparity: An exploratory study

It was hypothesized that viewing an object under conditions of continually varying binocular disparity would result in the perception of a “real” object that would continually change its shape, yet retain its three-dimensionality. It was further hypothesized that observed changes would be systematically sequential and repetitive, reflecting systematic and repetitive changes in the stimulus conditions. Two Ss were used. They were shown 12 objects (one at a time) by means of the Groman Continuous Binocular Disparator. An analysis was made from taped verbal reports. The hypotheses were strongly supported. Other phenomena were noted and described. The observations were categorized on the basis of three types of breakdown of veridicality. Differences between the frequency of breakdown of veridicality in the three categories were found and discussed in terms of a functional theory of veridical perception.     

Attitudes and beliefs as verbal behavior

Attitudes and beliefs are analyzed as verbal behavior. It is argued that shaping by a verbal community is an essential part of the formation and maintenance of both attitudes and beliefs, and it is suggested that verbal communities mediate the important shift in control from events in the environment (attitudes and beliefs as tacts) to control by other words (attitudes and beliefs as intraverbals). It appears that both attitudes and beliefs are constantly being socially negotiated through autoclitic functions. That is, verbal communities reinforce (a) reporting general rather than specific attitudes and beliefs, (b) presentation of intraverbals as if they were tacts, and (c) presentation of beliefs as if they were attitudes. Consistency among and between attitudes, beliefs, and behavior is also contingent upon the reinforcing practices of verbal communities. Thus, attitudes and beliefs can be studied as social behavior rather than as private, cognitive processes.     

MACHINES, BRAINS, AND PERSONS

Abstract. This paper explores the suggestion that our conscious experience is embodied in, rather than interactive with, our brain activity, and that the distinctive brain correlate of conscious experience lies at the level of global functional organization. To speak of either brains or computers as thinking is categorically inept, but whether stochastic mechanisms using internal experimentation rather than rule-following to determine behavior could embody conscious agency is argued to be an open question, even in light of the Christian doctrine of man. Mechanistic brain science does nothing to discredit Christian experience in dialogue with God or the Christian hope of eternal life.     

The acquisition and maintenance of behavioral skills: a response to Michael

A response to Michael's (1980) presidential address to the Association for Behavior Analysis is presented. The position is taken that in many instances we have failed to adopt a behavioral approach to dealing with problems within our field concomitant with the shift from an emphasis on behaviorism and a science of behavior to technology. It is argued that we need to be sensitive to the data and consider the contingencies that are operating within the culture. A general strategy and some tactics are presented to acquire and maintain behavioral skills.     

Traits,states, situations,and uncertainty

The shift of paradigm from psychodynamic therapy to behavior modification has changed the views of assessment and challenged traditional broad trait concepts. Behavioral assessment has used narrow, situation-specific trait tests, state self-report tests given in situations, and behavioral observations and performance ratings. Comparison of these types of measures are reported from a study of fear reactions in three situations. Narrow trait measures are generally more predictive of behavior than broad trait measures. State measures are even more predictive when given just before the performance. But only a sampling of such state measures can be used to define a trait because of the lower reliability of states. It is argued that behavior in situations is only predictable when an adequate number of behavioral samples is used.     

Aggression and Fire: Antisocial Behavior in Firesetting and Nonfiresetting Juvenile Offenders

This study examined the association between firesetting and antisocial behavior in 219 juvenile offenders. The study showed, through a series of a priori model comparisons using confirmatory factor analysis, that reliable data on both firesetting (n = 85) and nonfiresetting (n = 134) juvenile offenders best fit a 3-factor model composed of aggressive, nonaggressive, and oppositional antisocial behavior. Although the same general structure of antisocial behavior best fit the data for both groups, the firesetting group exhibited a significantly higher variety and frequency of aggressive and total antisocial acts and an earlier age of index arrest. It is argued that results from this study support a conceptualization of firesetting as accompanying serious and versatile antisocial behavior. Consistency with an early starter pattern of antisocial behavior among firesetting offenders is noted, and evidence suggesting that firesetting is indicative of developmentally advanced, serious, and varied antisocial behavior among troubled youth is discussed.     

Saccades compress space, time and number

It has been suggested that space, time and number are represented on a common subjective scale. Saccadic eye movements provide a fascinating test. Saccades compress the perceived magnitude of spatial separations and temporal intervals to approximately half of their true value. The question arises as to whether saccades also compress number. They do, and compression follows a very similar time course for all three attributes: it is maximal at saccadic onset and decreases to veridicality within a window of approximately 50ms. These results reinforce the suggestion of a common perceptual metric, which is probably mediated by the intraparietal cortex; they further suggest that before each saccade the common metric for all three is reset, possibly to pave the way for a fresh analysis of the post-saccadic situation.     

Visual perception during naturalistic near-death out-of-body experiences

This study attempted to ascertain the most appropriate content and placement of visual stimuli in a hospital-based study of the veridicality of out-of-body perception in the near-death experience (NDE), and the likelihood that a subject in such a study would notice, clearly perceive, and accurately recall a visual stimulus. Based on the questionnaire responses of 63 subjects who had near-death out-of-body experiences (ND OBEs), at least some of the respondents described sufficiently complete and accurate visual perception during the experience to warrant the pursuit of veridicality research in hospitals. Recommended stimulus content for such research includes a surface with intense color and lighting, and simple number and/or letter combinations. Stimuli should be as far below ceiling level as possible while maintaining double-blind criteria. Some characteristics of the individual NDE and NDEr may affect veridical perception during the ND OBE.This paper was derived in part from her Ed.D. dissertation submitted to the Northern Illinois University Graduate School.     

Compression as a Universal Principle of Animal Behavior

A key aim in biology and psychology is to identify fundamental principles underpinning the behavior of animals, including humans. Analyses of human language and the behavior of a range of non‐human animal species have provided evidence for a common pattern underlying diverse behavioral phenomena: Words follow Zipf's law of brevity (the tendency of more frequently used words to be shorter), and conformity to this general pattern has been seen in the behavior of a number of other animals. It has been argued that the presence of this law is a sign of efficient coding in the information theoretic sense. However, no strong direct connection has been demonstrated between the law and compression, the information theoretic principle of minimizing the expected length of a code. Here, we show that minimizing the expected code length implies that the length of a word cannot increase as its frequency increases. Furthermore, we show that the mean code length or duration is significantly small in human language, and also in the behavior of other species in all cases where agreement with the law of brevity has been found. We argue that compression is a general principle of animal behavior that reflects selection for efficiency of coding.
