Visual evoked potential augmenting/reducing slopes in cats—2. Correlations with behavior

Relationships were studied in cats between the augmenting/reducing slopes of visual evoked potentials (VEP) and three types of behavioral responses: learning and performance measures in (1) fixed interval (FI), and (2) differential reinforcement of low rate of response (DRL) bar pressing tasks for food reward, and (3) the effect of noise stress or increasing task difficulty on performance of an FI, DRL or 2 bar discrimination task. The most reliable slope measure (N1 at a medium intensity range) was found to correlate most highly with inhibitory behaviors such that reducers were most successful in controlling bar pressing behavior during an inhibitory DRL task or when stress was introduced. At a higher range of flash intensity slopes tended to be more negative, and the P1 - N1 slopes although more variable correlated most consistently with general temperament. Augmenters at a high intensity range were more active and explaratory, and learmed to bar press more quickly and efficiently.     

Racial Diversity in U.S. Congregations, 1998–2019

Racially diverse congregations have become an important part of the American religious landscape. We use data from the National Congregations Study (NCS), notably including data from the fourth wave, collected in 2018–2019, to examine 20 years of racial diversity in congregations. We find that racial diversity within congregations has increased substantially between 1998 and 2019. There are more congregations in which no one racial or ethnic group comprises more than 80 percent of the people, congregations’ average diversity level has increased, and the percentage of all-white congregations has declined. Nearly a quarter of evangelical churches now have no one ethnic group constituting more than 80 percent of the people, a rate comparable to what we observe among Catholic churches. Moreover, congregations that meet this 80-percent threshold are more likely to be led by black clergy in 2019 than they were in 1998. We end with a note of caution about concluding that diverse congregations necessarily promote racial justice.     

Does grasping in patient D.F. depend on vision?

A recently published study of grasping in patient D.F. challenges the well-known dissociation between vision-for-perception and vision-for-action, suggesting instead that D.F.'s preserved grip scaling depends entirely on haptic feedback. We argue that the results of the study are in fact fully consistent with the perception-action account.     

Examining U.S. drivers’ characteristics in relation to how frequently they engage in speeding on freeways

Speeding and speed-related crashes have consistently represented over 25% of all traffic fatalities over the past two decades. The severity of these speed-related incidents not only impact the drivers but all road users. Thus, characterizing drivers who speed, understanding their motivations, and identifying the types of risky driving behaviors associated with speeding play a critical role in developing, implementing, and sustaining effective countermeasures. Using a survey administered to a U.S. nationally representative sample (N = 2,930 licensed drivers aged 16 or older), this study develops a partial proportional odds model to examine differences in characteristics between types of speeders – frequent, occasional, and non-speeders – and explores characteristics and risk driving behaviors that are most associated with speeding behavior. Additionally, motivations for speeding are examined for drivers who frequently speed compared with those who occasionally speed. Results show speeders tended to engage in other unsafe driving behaviors, such as distracted, aggressive, unbelted, and alcohol-impaired driving. Among demographic and socio-economic variables examined in this study, drivers’ age was the greatest associated determinant. The association with engagement in red-light running, however, outweighed that with drivers’ age. Interestingly, the interaction between educational attainment and engagement in aggressive driving was also predictive of speeding behavior. For motivations for speeding, frequent speeders were more likely to report enjoying driving fast and disagreeing with speed limits compared with occasional speeders. The findings of this study are useful towards identifying the various characteristics and behaviors of drivers who engage in speeding, which can provide future insights into where effective countermeasures and prevention efforts should be focused.     

Why wasn't O.J. convicted? Emotional coherence in legal inference

This paper evaluates four competing psychological explanations for why the jury in the O.J. Simpson murder trial reached the verdict they did: explanatory coherence, Bayesian probability theory, wishful thinking, and emotional coherence. It describes computational models that provide detailed simulations of juror reasoning for explanatory coherence, Bayesian networks, and emotional coherence, and argues that the latter account provides the most plausible explanation of the jury's decision.     

The messianic temporality of theatre in I. L. Peretz’s At Night in the Old Marketplace

Theatre, as an art form that unfolds through time and moulds temporal experience, engages with its surrounding culture’s temporal imagination, the ways in which society conceives time, its movement, structures, and meaning. I. L. Peretz’s enigmatic and avant-garde Yiddish drama, At Night in the Old Marketplace, utilizes this potential of the theatre to tackle the question of messianic time and the ways in which it can be realized on the stage. By evoking Jewish traditions regarding the Messiah, religious nocturnal rituals, and the dynamics of Carnival, Peretz reconfigures messianic time as a radical, recurring yet fleeting, temporal experience. Theatrical temporality has affinities with messianic time because both are transitory and charged, condensed and ephemeral, and disjointed from the experience of time in everyday life. Rather than imagining messianic time as an eternal future to be awaited, Peretz’s play invites us to ponder in the theatre about the possibility of a messianically charged, albeit always fleeting, present.     

Comment on ‘counselling in dyslexia’ by T. R. Miles

Using as examples, the problems encountered when counselling dyslexics and their families, Professor Miles has drawn attention to a number of interesting issues which are relevant not only in counselling dyslexics, but also in counselling in general and, indeed in all forms of intervention and the giving of advice. I propose to deal with just three of those, namely the relationship between the counsellor and clients, diagnostic labels and ‘brussel-sprout therapies’.     

Gender Differences in U.S. College Students�� Fear for Others

This study examines U.S. college students?? fear of crime for others and uses the ??doing gender?? perspective to help explain gender differences. A sample of 931 college students (421 male students/510 female students and 605 White students/326 Black students) under the age of 30 from a Southeastern public university provided information on fear of crime, fear for others, and other variables often associated with fear of crime. When splitting the sample by gender, results suggest that both male and female college students fear for others, but do so in very different ways. While male students?? fear for others was associated with their personal characteristics (race, age and parental status) and whether they lived with an intimate, female students?? fear for others was most influenced by constrained behaviors and personal fear of crime. Additionally, when testing race specific models, there were not enough minority men to split the sample for men. However, when separating the sample by race for women only, the model generally did not work for non-White women, while the model worked well for White women. Overall, the results suggest that younger individuals?? fear of crime for others is gendered, associated with living status for men and personal fear for women and that racial differences among men and women should be examined in the future.

Race/ethnicity and sex in U.S. occupations, 1970–2010: Implications for research,practice, and policy

We used census data on the civilian non-institutional adult population to analyze trends in labor force participation by race/ethnicity and sex in U.S. occupations from 1970 to 2010 in decennial periods. We examined these data for the main effects and interactions of race/ethnicity and sex across the total labor market and within 35 detailed occupations. Results from a log-linear analysis revealed that, as a whole (across race/ethnicity), more women participated in the labor force from 1970 to 2010. The proportions of working racial/ethnic minorities to both the population and the people in the labor force increased across all decades except for Black men. Although White (Caucasian) men continuously comprised the largest racial/ethnic–sex group working across five decades in absolute numbers, their percentage of the total working population declined from 1970 (54%) to 2010 (37%). In our analyses of 35 occupations, significant sex differences within racial/ethnic groups emerged. Overall, with some exceptions, Asian men and women and White women were more likely to be absorbed into occupations typically associated with professional status whereas Black, Hispanic, and American Indian men and women were more likely to be absorbed into occupations typically associated with low skill, low wages, and low status. Implications for the role of psychologists in future research, practice, and policy are discussed.     

Are we ready for sexual reorientation therapy in the U.S. military? A response to David W. Lutz.

In his paper "The Catholic Church, the American Military, and Homosexual Reorientation Therapy," David W. Lutz ultimately concludes that it is "appropriate, and highly ethical" for the American military to offer reorientation therapy to help homosexuals overcome "the vice of sodomy." The major thrust of his paper, however, is to call for abandonment of the "Don't Ask/Don't Tell" policy currently in place in the military. Lutz's paper covers much ground, and this review begins by examining whether such a wide view is necessary for the ultimate conclusions. It goes on to ask whether Lutz has omitted to mention important considerations bearing on this issue, and whether Lutz's call for the introduction of reorientation therapy is a serious call or a symbolic response to homosexual activities. Lutz fails to address essential issues such as the actual experiences of other nations having homosexuals in the military, and issues regarding what constitutes "reorientation therapy," the latter leading to questions about how such a therapy would actually be implemented.     

A. “Verification” of statements in psychology

(1) In contradistinction to mathematics, physics and biology, psychology and psychiatry deal to a large extent with the verbal behaviour of their objects. They are faced with two kinds of sense-problems: those with which the observer has to do in his theory-construction, and those which are characteristic of the verbal behaviour of his subjects.(2) Apart from a schematic and simplified usage, as it occurs in filling-up exercises and other laboratory verbal behaviour, the psychologist has to do with statements the sense of which, on the one hand, is determined by the usage of his subjects and, on the other hand, so far as his records and theory are concerned, by his own language-sense.(3) This situation may give rise, and often gives rise, to all kinds of verbal confusions. If we call object-language the language used in verbal behaviour of people which psychology investigates and meta-language the language psychology uses in its discourse about the verbal behaviour of people, it becomes obvious that in present-day psychology the two languages are inextricably mixed together. The language of the subject is I-language, that of the observer, in relation to the subject, is he-language. Both, investigators and investigated, often use terms without referents or with only verbal associations. There can be a great dispersion between the sense of statements used by the subject and that of statements used by the observer.(4) The use of physical language is not a remedy against a confusing terminology. One can tell highly speculative stories in physical language. The empirical verification of statements used by the investigator would require naming the concrete operations involved in testing them.(5) Objective, in the sense of a class of responses yielding maximum reliability coefficients within or between individuals facing a common observational situation or situational element, refers to a criterion to which the protocol of the tester is subjected. An investigation into the way in which subjects verify their, often mainly emotive, statements requires other means (e.g. looking at the way in which they justify their behaviour or trying to break through the chain of their verbal associations (circular reasonings)).     

Feedback suppression in anesthesia. Is it reversible?

Information processing that subserves conscious cognitive functions is thought to involve recurrent signaling through feedforward and feedback loops among hierarchically arranged functional regions of the cerebral cortex. In the current issue of Consciousness and Cognition, Lee et al. report that loss of consciousness, as produced by a bolus injection of the general anesthetic propofol to human volunteers, was accompanied by a decrease in wide-band EEG feedback connectivity from frontal cortex to parietal cortex, confirming a prediction from previous experimental studies. Interestingly, frontoparietal feedback connectivity did not fully recover after the anesthetic effect wore off and the subjects first opened their eyes in response to a verbal command. Possible interpretations of the results and their implications with respect to the neural correlates of consciousness and unconsciousness are discussed.     

The Skolem-Löwenheim theorem in toposes. II

This paper is a continuation of the investigation from [13]. The main theorem states that the general and the existential quantifiers are (, -reducible in some Grothendieck toposes. Using this result and Theorems 4.1, 4.2 [13] we get the downward Skolem-Löwenheim theorem for semantics in these toposes.
