Virtue and Luck, Epistemic and Otherwise

This essay defends virtue reliabilism against a line of argument put forward by Duncan Pritchard. In the process, it discusses (1) the motivations for virtue reliabilism, (2) some analogies between epistemic virtue and moral virtue, and (3) the relation between virtue (epistemic and otherwise) and luck (epistemic and otherwise). It argues that considerations about virtue and luck suggest a solution to Gettier problems from the perspective of a virtue theory.     

Self- and supervisory perspectives on age and work attitudes and performance.

Person- and context-oriented definitions of age were used to predict three sets of work outcomes: work attitudes, performance ratings, and reports of developmental practices. The five age measures included employee chronological age, employee subjective age (i.e., self-perceptions of age), and social age (i.e., others' perceptions of age), as well as self- and supervisors' perceptions of the employee's relative age (i.e., compared with the employee's work group). The study assessed (a) the relationships among the age measures, (b) the additive relationships among the age measures that predicted work outcomes, and (c) the interactive relationships among the age measures that predicted work outcomes. Each prediction received some support except for (b). Furthermore, many of the age--work-outcome relationships were replicated in the managerial sample. Implications for the use of alternative age measures are discussed.     

Presentation- and test-trial effects on acquisition and retention of distance and location

Acquisition and retention effects of presentation and test trials on movement distance (Experiment 1) and location (Experiment 2) were examined under three multitrial training methods. Three groups of 15 government employees performed three training trial cycles consisting of six trials each. Training methods emphasized either presentation-trial repetition, test-trial repetition, or presentation- and test-trial alternation within cycles. After training, both short- (3 min.) and long-term (24 hr.) retention scores were recorded. Absolute error revealed that (a) presentation-trial repetition promoted acquisition of both distance and location but resulted in extensive short- and long-term forgetting; (b) test-trial repetition produced error increases within cycles, potentiated presentation-trial effectiveness during acquisition, and enhanced long-term retention of both distance and location; (c) presentation- and test-trial alternation promoted distance and location acquisition and produced distance retention intermediate to that of the other two methods. Experiment 3 provided data to support the interpretation that test-trial retention benefits are a function of movement execution mode.     

Consonant and vowel perception and production: early English-French bilinguals and English monolinguals

This study is a comparative analysis of the English phonetic systems of 10 fluent adult English-French bilinguals who acquired their two languages prior to age 8 and who were English-dominant, and of 10 adult English monolinguals. The objective of the study was to determine whether or not early English-dominant bilinguals perceive and produce speech as English monolinguals do. Discrimination and identification tests of synthetic (d-t) and (i-I) continua and speech production tests revealed that the bilinguals' discrimination and production of (d) and (t) and their production of (I) did not differ significantly from the monolinguals'. However, the bilinguals' identification of (d-t) and (i-I) and one aspect of their production of (i) did differ significantly from that of the monolinguals. The present results indicate that early bilingualism can yield monolingual-like performance in at least one of the bilinguals' languages, but only with respect to certain aspects of the phonetic system. These findings are viewed in light of sound-class distinctions, the perception-production dichotomy, and bilingual phonetic transfer and restructuring.     

Substance use and abuse among children and teenagers

During the past several years, there has been a renewed national concern about drug abuse, culminating in the current "war on drugs." In this review, we emphasize that even though child or teenage drug use is an individual behavior, it is embedded in a sociocultural context that strongly determines its character and manifestations. Our focus is on psychoactive substances both licit (cigarettes and alcohol) and illicit (e.g., cannabis and cocaine). We feel that it is critical to draw a distinction between use and abuse of drugs and to do so from a multidimensional perspective that includes aspects of the stimulus (drug), organism (individual), response, and consequences. Our selective review of substance use and abuse among children and adolescents covers epidemiology (patterns and extent of drug use), etiology (what generates substance use), prevention (how to limit drug use), treatment (interventions with drug users), and consequences (effects and outcomes of youthful drug use).     

Facial and vocal cues of deception and honesty

Facial expressions and vocal cues (filtered speech) of honest and deceptive messages were examined in posed and spontaneous situations. The question of interest was the degree to which nonverbal cues transmit information about deception. Results indicated that (a) for both the facial and vocal channels, posing (as compared to spontaneous behavior) produced a higher level of communication accuracy; (b) facial expressions of deceptive (as compared to honest) messages were rated as less pleasant, while vocal expressions of deception were rated as less honest, less assertive, and less dominant, particularly in the posed condition; (c) the sender's ability to convey honesty was negatively correlated with his/her ability to convey deception, suggesting the existence of a demeanor bias—individual senders tend to appear and sound consistently honest (or dishonest) regardless of whether they deliver an honest or a deceptive message; (d) in the posing condition, the sender's abilities to convey honesty/deception via facial and vocal cues were positively and significantly correlated, whereas in the spontaneous condition they were not; and (e) senders whose full (unfiltered) speech indicated more involvement with their responses were judged as more honest from both their vocal (filtered speech) and facial cues, in both the honest and deceptive conditions.     

Negative and positive components of psychological masculinity and femininity and their relationships to self-reports of neurotic and acting out behaviors

Negatively valued masculinity (M-) and femininity (F-) personality scales were developed to supplement the positively valued Masculinity (M+) and Femininity (F+) scales of the Personal Attributes Questionnaire (PAQ; Spence & Helmreich). M- consisted of traits that had been judged to be (a) more typical of males than females, (b) undesirable in both sexes, and (c ) agentic or instrumental in content. Two F- scales were developed, both containing stereotypically feminine, undesirable traits, one set of traits referring to communionlike characteristics (Fc-) and the other to verbal passive-aggressive qualities (FVA-). Significant sex differences in the predicted direction were found on all scales. In both sexes, low and typically nonsignificant correlations were found between parallel positive and negative scales, but highly significant negative correlations were found between positive and negative cross-sex scales. These findings provide additional evidence for the multidimentionslity of masculinity and femininity. Scores on a self-esteem measure were positively correlated with M+ and F+, uncorrelated with M-, and negatively correlated with the F- scales. Different patterns of scores were associated with two types of problem behaviors. In both sexes, neuroticism was most highly correlated (in a negative direction) with M+, and acting out behavoir was most strongly correlated (in a positive direction) with M-. The next highest correlation in both instances was with FVA-.     

Genetic and environmental influences on girls' and boys' gender-typed and gender-neutral values

In this first investigation of genetic and environmental influences on children's values, 271 German twin pairs (50.2% boys) reported their values at ages 7-11 years using the Portrait Values Questionnaire (Schwartz & Rubel, 2005). We distinguished between gender-neutral (conservation vs. openness to change) and gender-typed (self-transcendence vs. self-enhancement) values. Boys differed from girls in the importance given to gender-typed benevolence, achievement, and power values. Gender-neutral values showed moderate (.34) and gender-typed values showed higher (.49) heritability, with nonshared environment and error accounting for the remaining variance. For both sexes, substantial genetic effects accounted for the importance children gave to their respective gender-stereotypical end of the self-transcendence versus self-enhancement dimension. However, dramatic sex differences emerged in the gender-atypical end of the distribution. For girls, low self-transcendence (high gender-atypical values) showed a large (.76) group heritability. For boys, gender-atypical values (high self-transcendence) showed no heritability and a modest (.10) shared environment effect.     

Romantic jealousy and implicit and explicit self-esteem

Research on romantic jealousy and self-esteem mostly relies on the measurement of explicit (i.e., conscious, deliberate) aspects, without taking recent developments of the measurement of implicit (i.e., automatic) aspects into account. In this study (N = 154), we applied several measures of romantic jealousy and self-esteem (explicit, implicit), finding sex-specific as well as measurement-specific effects. Men (but not women) higher in jealousy had lower explicit self-esteem, whereas women (but not men) higher in jealousy had higher implicit self-esteem, but only when using the Implicit Association Test (whereas not the Initial Preference Task) for measuring implicit self-esteem. Individuals with damaged (i.e., low explicit and high implicit) self-esteem were more jealous than those with fragile (i.e., high explicit and low implicit) self-esteem. This differential effect was due to higher implicit self-esteem among women, whereas lower explicit self-esteem among men. These novel findings not only add to the expanding literature on romantic jealousy research, but also to research on self-esteem discrepancies.     

Word order and finiteness in Dutch and English Broca's and Wernicke's aphasia

The effect of two linguistic factors in Broca's and Wernicke's aphasia was examined using Dutch and English subjects. Three tasks were used to test (1). the comprehension and (2). the construction of sentences, where verbs (in Dutch) and verb arguments (in Dutch and English) are in canonical versus non-canonical position; (3). the production of finite versus infinitive verbs. Proportions of errors as well as types of errors made by each aphasic group are similar on the sentence comprehension and sentence anagram tasks. On the verb production task the performance pattern is, again, the same, but the error types are different. The discussion focuses on how the similarities and differences across languages and across aphasia types may be interpreted with respect to the underlying deficit in Broca's and Wernicke's aphasia.     

ADHD and college students: exploratory and confirmatory factor structures with student and parent data

Exploratory factor analyses (EFAs) and confirmatory factor analyses (CFAs) were used to investigate the structure of the Student Report Inventory (SRI) and Parent Report Inventory (PRI) of the College Attention-Deficit/Hyperactivity Disorder (ADHD) Response Evaluation. The sample was composed of 1,080 college students and their parents and was stratified by ethnicity, gender, ability level, age, grade, region of residence, and psychoeducational classification status. Results varied according to the information source (self-report vs. parent). EFA uncovered and CFA confirmed 3 distinct and reliable dimensions for student reports: Inattention, Hyperactivity, and Impulsivity. By contrast, EFA and CFA uncovered a reliable 2-dimension structure for the parent-report data. Factor structures replicated across genders (3 factors for the SRI, and 2 factors for the PRI). Results are discussed in terms of the divergence of structures.     

Women and weight: fad and fiction

In this article, I argue that women's concern with body weight is a "fad," when taken in an historical context, and is limited to Western societies. I have presented evidence that the following aspects of weight are myths rather than reality: (a) There are objective definitions of obesity; (b) obesity is prevalent among women; (c) obese people take in more calories than the nonobese; (d) dieting is an effective way to reduce weight; and (e) obesity is related to poor physical health.     

Preverbal and verbal counting and computation.

We describe the preverbal system of counting and arithmetic reasoning revealed by experiments on numerical representations in animals. In this system, numerosities are represented by magnitudes, which are rapidly but inaccurately generated by the Meck and Church (1983) preverbal counting mechanism. We suggest the following. (1) The preverbal counting mechanism is the source of the implicit principles that guide the acquisition of verbal counting. (2) The preverbal system of arithmetic computation provides the framework for the assimilation of the verbal system. (3) Learning to count involves, in part, learning a mapping from the preverbal numerical magnitudes to the verbal and written number symbols and the inverse mappings from these symbols to the preverbal magnitudes. (4) Subitizing is the use of the preverbal counting process and the mapping from the resulting magnitudes to number words in order to generate rapidly the number words for small numerosities. (5) The retrieval of the number facts, which plays a central role in verbal computation, is mediated via the inverse mappings from verbal and written numbers to the preverbal magnitudes and the use of these magnitudes to find the appropriate cells in tabular arrangements of the answers. (6) This model of the fact retrieval process accounts for the salient features of the reaction time differences and error patterns revealed by experiments on mental arithmetic. (7) The application of verbal and written computational algorithms goes on in parallel with, and is to some extent guided by, preverbal computations, both in the child and in the adult.     

Levels of consensus and majority and minority influence

Three experiments are reported which examine the effects of consensus information on majority and minority influence. In all experiments two levels of consensus difference were examined; large (82% versus 18%) and small (52% versus 48%). Experiment 1 showed that a majority source had more influence than a minority source, irrespective of consensus level. Experiment 2 examined the cause of this effect by presenting only the source label (‘majority’ versus ‘minority’), only the consensus information (percentages) or both. The superior influence of the majority was again found when either (a) both source label and consensus information were given (replicating Experiment 1) and (b) only consensus information was given, but not when (c) only the source label was given. The results showed majority influence was due to the consensus information indicating more than 50% of the population supported that position. Experiment 3 also manipulated message quality (strong versus weak arguments) to identify whether systematic processing had occurred. Message quality only had an impact with the minority of 18%. These studies show that consensus information has different effects for majority and minority influence. For majority influence, having over 50% support is sufficient to cause compliance while for a minority there are advantages to being numerically small, in terms of leading to detailed processing of its message.

Toward a Feminist and Multicultural Model of Consultation and Advocacy

The authors present core ideas or constructs that might be integral to a feminist and multicultural model of consultation. According to the model, the structure of consultation is (a) nonhierarchical and (b) an open triad (incorporating extrapersonal and outside factors). The process of consultation is (c) culturally responsive and (d) empowering. The role of the consultant is as (e) an agent for change and (f) an advocate for both the client and the system. Los autores y sus ideas centrales presente o construyentes quizás sea integral para una feminista y un modelo de la consulta multicultural. Según el modelo, la estructura de la consulta es (a) nonhierarchical y (b) una tríada abierta (incorporando extrapersonal y factores exteriores). El proceso de la consulta es (c) culturalmente receptiva y (d) autorizada. El papel del consultor es como (e) un agente para el cambio y (f) un defensor para el cliente y el sistema.     

Attention and memory in children and adults in context-interactive and context-independent situations

The relation between attention to target and context information and target recall in an incidental learning task for children and adults was examined in seven experiments. In Experiment 1, second- and sixth-graders and college adults were presented with hard (e.g., hawk eagle canary), easy (river lake canary), or unrelated (river pencil canary) word triplets, varying in the difficulty of identifying the “odd” target word (canary), and were required to identify the target themselves (oddity choice), or such identification was optional, since the experimenter identified the target (read). Trial duration was either 3 or 7 s. The attentional patterns varied with triplet type, orienting activity, and trial duration. Most important, target and incidental context word recall seemed to vary directly with the extent of the interactive processing of context and target conceptual information, and the adults seemed more disposed to do such processing than the children. These results support a distinction between context-interactive and context-independent situations and suggest that the attentional patterns that are efficient for memory may differ with the kind of situation. The other experiments extend and establish the generality of these results.     

Creation and the Symbiosis of Science and Judaism

It seems to me that the critical questions that science and natural philosophy raise for Jewish theology are the following: Does God evolve? Does the universe have or even need an interpretation, specifically with reference to the fact that most of the universe most of the time is uninhabitable, and there may be many more than one universe? Does the universe need a beginning? What is distinctive about human consciousness, intelligence, and ethics in the light of evidence for evolution from all of the life sciences? Finally, will both life and the universe end? These questions are not only modern. They contain all the primary issues that have dominated rabbinic thought. That agenda can be summarized in six topics: How should we model what we believe about (1) God, (2) the world, and (3) the human being; and how should we understand the relations between them, that is, between (4) God and the world (or, creation), (5) God and the human (or, revelation), and (6) the human and the world (or, redemption)? In this paper I focus on the fourth issue, creation. My answer is presented in detail in my Judaism and the Doctrine of Creation(Samuelson 1994). Here I shall summarize my conclusions there concerning science, Jewish texts, and the correlation between them.     

Reactive and proactive control in incarcerated and community adolescents and young adults

This study compared the cognitive control skills of male incarcerated adolescents (n = 44), male control adolescents (n = 33), male incarcerated young adults (n = 41), and male control young adults (n = 35) using the AX-continuous performance test (AX-CPT). This test measures proactive control (the ability to maintain a mental representation of goal-related information in preparation for a behavioral response) and reactive control (the ability to activate goal-related information in response to an external trigger). Incarcerated individuals had more difficulty implementing proactive control, whereas control individuals had more difficulty implementing reactive control. Adolescents had more difficulty with both reactive and proactive control compared with young adults, suggesting that both skills improve with age. Additional analyses indicated that the effect of age on proactive control was due to the presence of attention-deficit/hyperactivity disorder, whereas the effect of age on reactive control appeared to be a natural developmental trend that could not be explained by other variables. These findings are considered in relation to the dual mechanisms of control theory [Braver, T. S., Gray, J. R., & Burgess, G. C. (2007). Explaining the many varieties of working memory variation: Dual mechanisms of cognitive control. In A. R. A. Conway, C. Jarrold, M. J. Kane, A. Miyake, & J. N. Towse (Eds.), Variation in Working Memory. New York: Oxford University Press.].     

Sustained attentional and disattentional abilities and arousability: Factor analysis and relationships to hypnotic susceptibility

The neurophysiologically separate dimensions of deeply focused, sustained attention and arousability are shown to be differentially related to hypnotic susceptibility. University undergraduates, 98 men and 112 women, were administered the Harvard Group Scale of Hypnotic Susceptibility; the Group Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C); and questionnaires that assessed attentional abilities (Differential Attentional Processes Inventory (DAPI), Tellegen Absorption Scale (TAS)), Extraversion (Eysenck Personality Questionnaire), strength of the nervous system (Strelau Temperament Scale (STS)), augmenting-reducing (Vando Reducer-Augmenter Scale (RAS)), and emotionality (Affect Intensity Measure (AIM)). Women were significantly higher on TAS, DAPI dual attention physical-cognitive scale, and AIM; men were significantly higher on TAS and STI Strength of Excitation Scale. Separate factor analyses for men and women separately yielded fairly similar four-factor solutions. The first major factor, defined by DAPI Moderately Focused Attention and Dual Attention scales, represented moderately sustained attention in a complex environment with limited interference from competing stimuli. The extremely involved and focused attention factor, defined by the TAS and DAPI Extremely Focused Attention Scale, had hypnotic susceptibility loaded more strongly for men than women. The arousability factor was defined by EPQ Extraversion, STI Mobility of Nervous System (MNS) scale, and RAS. The neo-Pavlovian nervous system processes factor was defined by the STI Strength of Excitation and Strength of Inhibition scales; the STI MNS scale also loaded on this factor for men. Only for women were introverts more hypnotizable than extraverts. Results support H. J. Crawford and J. H. Gruzelier's (1992) in E. Fromm and M. Nash (Eds.) Contemporary Perspectives in Hypnosis Research (pp. 227–266) New York: Guildford Press) neurophysiological model of hypnosis that proposes that highly hypnotizable persons have a more efficient fronto-limbic sustained attentional and disattentional system.     

Holocaust and resistance

This article deals with the following themes: (1) Nazi malevolence in selecting Jewish holidays as dates for some of their most barbarous action; (2) U.S. official observance of the Holocaust; (3) the irresponsible use of the term Holocaust and its precise use; (4) because of extermination of two-thirds of the Jews of Europe, the world Jewish population in 1979 is still 4 million less than in 1933; (5) are we “all guilty?” (6) are we “all Survivors?” (7) were we “all at Auschwitz?” (8) demystification of the Holocaust as a comprehensible event in twentieth-century history; (9) why “never to forgive?” and (10) the quality and extent of resistance.
