Approaches to Adolescent Smoking Cessation and Education

The role of the school in the control of smoking among adolescents is explored. Incidence and trends of smoking among youth are discussed and health consequences of smoking are explored. The role of the school in smoking prevention, cessation, and regulation also is described. Innovative educational strategies to prevent smoking are reviewed and model programs are described. School-based smoking cessation programs are reviewed and suggstions are made for the development of local programs. School policies on smoking are given. Recommendations are given for a comprehensive school program to control smoking.     

Computational and statistical methods for analyzing event-related potential data

Some computational and statistical techniques that can be used in the analysis of event-related potential (ERP) data are demonstrated. The techniques are fairly elementary but go one step further than do simple area measurement or peak picking, which are most often used in ERP analysis. Both amplitude and latency measurement techniques are considered. Principal components analysis (PCA) and methods for electromyographic onset determination are presented in detail, and Woody filtering is discussed briefly. The techniques are introduced in a nontechnical, tutorial review style. One and the same existing data set is presented, to which the techniques are applied, and practical guidelines for their use are given. The methods are demonstrated against a background of theoretical notions that are related to the definition of ERP components.     

Feature importance in feature generation and typicality rating

Many theoretical models of cognition are based on the assumption that cognitive processes and representations are hierarchically structured. The issue of whether these hierarchies are mere constructs or conceptual tools, or whether they have psychological and neurological reality, is addressed. Theories across a range of cognitive domains are reviewed and four kinds of evidence are considered: behavioural, neuropsychological, ontogenetic, and logical. Logical constraints are identified in relation to operating principles of control, access, economy and analogy. The general characteristics of hierarchical structures and their advantages and disadvantages are discussed.     

Similarity semantics and minimal changes of belief

Different similarity relations on sets are introduced, and their logical properties are investigated. Close relationships are shown to hold between similarity relations that are based on symmetrical difference and operators of belief contraction that are based on relational selection functions. Two new rationality criteria for minimal belief contraction, the maximizing property and the reducing property, are proposed.     

The argument from almost indiscernibles

What I call the argument from almost indiscernibles is an argument, put forward by Robert Adams in 1979, for the possibility of indiscernibles based on the possibility of almost indiscernibles. The argument is that if almost indiscernibles are possible, indiscernibles are possible, but since almost indiscernible are possible, indiscernibles are possible. The argument seems to be an improvement over the mere appeal to intuitions, like that suggested by Max Black, that situations in which there are indiscernibles are possible, for the argument purports to give us a reason that indiscernibles are possible. In this paper I shall assess the argument by examining whether there is support for the conditional premise that if almost indiscernibles are possible, indiscernibles are possible. I shall argue that there are reasons to think that either the premise lacks support or almost indiscernibles are dispensable. If the premise lacks support, the argument does not establish the possibility of almost indiscernibles; if almost indiscernibles are dispensable, the argument is not needed to establish the possibility of indiscernibles.     

Testing Event-Based Forms of Causality

Three fundamental types of causal relations are those of necessity, sufficiency, and necessity and sufficiency. These types are defined in contexts of categorical variables or events. Using statement calculus or Boolean algebra, one can determine which patterns of events are in support of a particular form of causal relation. In this article, we approach the analysis of these forms of causality taking the perspective of the analyst of empirical data. It is proposed using Configural Frequency Analysis (CFA) to test hypotheses about type of causal relation. Models are proposed for two-variable and multi-variable cases. Two CFA approaches are proposed. In the first, individual patterns (configurations) are examined under the question whether they are in support of a particular type of causal relation. In the second, patterns that are in support are compared with corresponding patterns that are not in support. In an empirical example, hypotheses are tested on the prediction of sustainability of change in dietary fat intake habits.     

Structure and development of behavior systems

Behavior systems are particular organizations of cognitive structures that are called behavior mechanisms: perceptual, central, and motor. Thus, behavior systems are defined here in structural terms and not in terms of their functional characteristics. In young animals, behavior mechanisms often develop independently of functional experience, though specific types of experience are usually necessary for integrated systems to develop. These concepts are illustrated here by the dust-bathing, feeding, aggressive, and sexual systems of the fowl, which are considered to be typical of behavior systems in other species. Aspects of neural development are examined and found to facilitate our understanding of a wide range of developmental phenomena, such as critical periods and irreversibility. Finally, various examples of classical conditioning and instrumental learning are analyzed in terms of the type of structures involved, and they are related to general developmental processes.     

Events (Like Objects) Are Things,Can Have Affordance Properties,and Can Be Perceived

Stoffregen (target article, this issue) argues that events and affordances are qualitatively distinct properties; that affordances are animal and observer referential, whereas events are not; and that only affordances are perceived and events are not. In this commentary, I argue to the contrary-that events are perceived as well as affordances and that animals do not perceive disembodied properties anymore than they could perceive propertyless things. I argue that events are not properties but are substantial, spatiotemporal things that have properties. Events can exhibit affordances that must vary in scope to support the perceptually guided temporal evolution of behaviors.     

Recognition of affixed words and the word frequency effect

Three experiments are reported in which the word frequency effect is used as a diagnostic for determining whether affixed words coming from the same stem are stored together or separately in the lexicon. Prefixed words are examined in the first experiment, inflected words in the second and third. In the first two experiments, two types of word are compared where the words in each condition are matched on surface or presented frequency but are varied on the frequency of their stems or base frequency. It is found that lexical decision times are influenced by base frequency, thus indicating that words related by affixation are stored together in the lexicon. The third experiment, however, demonstrates that when base frequency is held constant and surface frequency is varied, lexical decision times are influenced by surface frequency. The results are accounted for by a model of word recognition whereby frequency has its effect at two different stages of the recognition process.     

The Portrayal of Men's Family Roles in Television Commercials

This study examines the portrayal of men infamily roles, as fathers and husbands, on televisioncommercials. A content analysis of commercials airedduring football, daytime, and prime time is carried out. The sample size of characters is 944, mostof whom are middle-class, non-Hispanic whites. Men withchildren but no spouse are more likely to be shownduring football than are women with children but no spouse. Advertisements for computers andelectronics are more likely to include men with childrenbut no spouse than women with children but no spouse.Men appearing alone with children are more likely to be shown outside than women alone withchildren. Men are less likely to be portrayed cooking,cleaning, washing dishes, and shopping than women. Menwithout spouses are more likely to be shown with boys and less likely to be shown with infants thanwomen without spouses. Men are infrequently shown takingcare of a child and are never shown caring for girls.However, men are often shown teaching, reading, talking, eating, and playing with children. Tothe extent that men are shown as more involved in familylife, they still tend to depend largely on knowledge andactivities that are stereotypically male.     

A Primer of the Values Implicit in Counseling Research Methods

The author attempts to answer 5 related questions: What are implicit values? Why are these values often considered problematic to traditional science? Why are such values necessary to research? What are the main values of traditional methods in psychology? What are the implications of a value‐laden science?     

Visual and auditory choice reaction times

Choice reaction times are measured for three values of a priori signal probability with three well-practiced observers. Two sets of data are taken with the only difference being the modality of the reaction signal. In one set of conditions it is auditory, in the other, visual. The auditory reaction times are faster than the visual and in addition several other differences are noted. The latency of the errors and correct responses are nearly equal for the auditory data. Error latencies are nearly 30% faster for the visual data. Non-stationary effects, autocorrelation between successive latencies and non-homogeneous distribution of errors, are clearly evident in the visual data, but are small or non-existent in the auditory data. The data are compared with several models of the choice reaction time process but none of the models is completely adequate.     

Substance Abuse Prevention:

Components of a successful substance abuse prevention program are discussed. Substance use and abuse trends in school-aged populations are briefly reviewed. Prevention program strategies deemed desirable through recent research efforts are incorporated in describing a model program. Educational approaches and substance abuse intervention strategies are differentiated. Program planning guideliens are presented and discussed. These guidelines are designed to establish and maintain school and community support for prevention programs.     

The Counseling Service in the Administrative Setting: Problems and Possible Solutions

Friction between counseling personnel and administrators affects the work of each. Background reasons for difficulties in working together are explored. Four areas offering possible remedial measures are examined: the nature of compromise, problems in communication, emotional health, and a framework for understanding behavior. Aspects of a program model are provided. Suggestions are made for specific areas in which data are needed and proposals for method are offered.     

Tau-equivalence and equipercentile equating

Test scores that are not perfectly reliable cannot be strictly equated unless they are strictly parallel [Lord, 1980]. This fact implies that tau-equivalence can be lost if an equipercentile equating is applied to observed scores that are not strictly parallel. Seventy-two simulated testing conditions are produced to simulate equating tests with different difficulties and discriminations. Number-correct and trait metrics are examined. When an equipercentile equating is applied to these data, locally biased (i.e., non-tau-equivalent) results are produced for tests of unequal difficulty. Differences between the criteria of tau-equivalence and equipercentile equivalence are discussed.     

Emotional Schema Therapy: A Meta‐experiential Model

The emotional schema model proposes that individuals differ in their interpretations, evaluations, and strategies about emotional experience. Fourteen dimensions that are related to problematic strategies of emotion regulation are identified. Specific interventions for several of these strategies are identified, and examples of implementation are described. Finally, problematic schemas about emotions—both on the part of patients and therapists—are described, and interventions for addressing these in therapy are provided.     

A Note on Formality and Logical Consequence

Logic is formal in the sense that all arguments of the same form as logically valid arguments are also logically valid and hence truth-preserving. However, it is not known whether all arguments that are valid in the usual model-theoretic sense are truth-preserving. Tarski claimed that it could be proved that all arguments that are valid (in the sense of validity he contemplated in his 1936 paper on logical consequence) are truth-preserving. But he did not offer the proof. The question arises whether the usual model-theoretic sense of validity and Tarski's 1936 sense are the same. I argue in this paper that they probably are not, and that the proof Tarski had in mind, although unusable to prove that model-theoretically valid arguments are truth-preserving, can be used to prove that arguments valid in Tarski's 1936 sense are truth-preserving.     

Are lies more wrong than errors? Accuracy judgments of inaccurate statements

People are often mistaken when estimating and predicting quantities, and sometimes they report values that they know are false: they lie. There exists, however, little research devoted to how such deviations are being perceived. In four vignette studies, participants were asked to rate the accuracy of inaccurate statements about quantities (prices, numbers and amounts). The results indicate that overstatements are generally judged to be more inaccurate than understatements of the same magnitude; self-favorable (optimistic) statements are considered more inaccurate than unfavorable (pessimistic) statements, and false reports (lies) are perceived to be more inaccurate than equally mistaken estimates. Lies about the future did not differ from lies about the past, but own lies were perceived as larger than the same lies attributed to another person. It is suggested that estimates are judged according to how close they come to the true values (close estimates are more correct than estimates that are less close), whereas lies are judged as deviant from truth, with less importance attached to the magnitude of the deviation.     

Law, liability, and the school psychologist: Malpractice and liability

A variety of court decisions and laws relevant to malpractice and liability of school psychologists are presented. Terms are defined and examples of faulty psychological testing, defamation, withholding information, and inferred incompetence are provided. Suggestions regarding litigation and legal defenses are made and issues related to professional liability insurance are discussed.
