Analogue drinking assessment: Sensation seeking and gender

This study assessed the relationship between sensation seeking measured as a trait variable and drinking behaviors observed unobtrusively in the laboratory. It was hypothesized that high-sensation-seeking subjects would consume more alcohol than low sensation seekers and experience greater enhancement of positive moods and body sensations associated with intoxication. Thirty female and 31 male subjects divided into high- and low-sensation-seeking subgroups participated in an ad libitum drinking situation with the manifest task of taste rating three types of vodka (actually 95% alcohol) or tonic. Dependent variables included beverage consumption, positive/negative mood states, body sensations, breath estimates of blood alcohol levels, and self-rated level of intoxication. All subjects reported feeling the effects of alcohol. Contrary to predictions, high-sensation-seeking subjects neither consumed more alcohol than their low-sensation-seeking counterparts nor drank more alcohol than tonic, Paradoxically, low-sensation-seeking women displayed significantly greater alcohol intake and intoxication than all other groups. Possible explanations for findings were considered as well as the necessity for multimethod assessments of both predictor (i.e., sensation seeking) and criterion (i.e., alcohol consumption) variables across time and situations.This research was supported by Grant Award AA04042-03 from the National Institute on Alcohol Abuse and Alcoholism to the first and third authors. Special Appreciation is expressed to Anne T. Patsiokas, Susan W. Altman, Victoria Molony-Sinnott, and Pamela J. Thompson for their invaluable assistance in collecting and analyzing the data.     

A note on ECG changes observed during Pavlovian conditioning in a rhesus monkey following coronary arterial occlusion

Changes in the ECG of a rhesus monkey during a classical aversive conditioning trial conducted 10 minutes after occlusion of the marginal branch of the left circumflex coronary artery have been observed. This appears to reflect an instance where myocardial ischemia following coronary occlusion was exacerbated by presentation of a conditional stimulus.     

Justice,instruction, and the good: The case for public education in Aristotle and Plato's Laws

This paper develops an interpretation and analysis of the arguments for public education which open Book VIII of Aristotle's Politics, drawing on both the wider Aristotelian corpus and on examination of continuities with Plato's Laws.Part II: Sections IV–VII examine the arguments for the first of the two conclusions which Aristotle advances in VIII. 1, namely that education is important enough to merit the legislator's attention. It is shown, through a development of links between Politics V and the arguments of VIII. 1, that Aristotle's two arguments for this conclusion are calculated to appeal to two distinct subgroups within his intended audience, those who would be moved by a desire to promote the common good, and those who could only be counted on to desire the preservation of their own rule.     

Justice,instruction, and the good: The case for public education in Aristotle and Plato's Laws

This paper develops an interpretation and analysis of the arguments for public education which open Book VIII of Aristotle's Politics, drawing on both the wider Aristotelian corpus and on examination of continuities with Plato's Laws. Part I: The paper opens with the question of why Aristotle would say that no one will doubt that education should be the concern of the legislator, and Sections I–III identify the nature of his enterprise in the Politics, the audience he wishes to address, the conclusions he seeks to establish in VIII. 1, and what public education would amount to for him. An important conclusion reached is that the first of Aristotle's two conclusions in VIII.1 has been routinely misidentified.     

Two-component arterial blood pressure conditional response in rat

The objective of these experiments was to quantify the pattern of change in arterial blood pressure (BP) during a discriminative aversive classical conditioning paradigm in rat using a new “high resolution” computer analysis. Sprague-Dawley rats (n=5) were restrained in a soft, conical cloth pouch and conditioned using a 6 sec. pulsed tone (CS+) followed by a 0.5 sec. tail shock; a steady tone, never followed by shock, served as a CS-. BP peaked at 16.4±6.5 mm Hg (mean±SD) above control at 1.5±0.1 sec. after onset of CS+. This “first component” (“C₁”) also occurred during CS- (12.1±3.8 mm Hg), although the magnitudes of the two were significantly (p<0.05) different. Another group of rats (n=8) was treated identically except the tones were 15 seconds long. The conditional BP response consisted of two components. C₁ was reminiscent of that seen using the short tone: for CS+ a peak of 13.6±5.6 mm Hg at 1.5 sec. or, for CS-, of 10.0±4.3 at 1.3 sec. (p<0.05). In CS+ trials BP peaked again (“C₂,” 7.4±2.5 mm Hg) at 8.3±1.2 sec. There was no statistically significant C₂ for CS- trials, clearly demonstrating discrimination between tones. The unconditional BP response in both groups consisted of two large, closely spaced peaks in BP. Respiration was recorded in 3 additional rats. After shock delivery these subjects often showed a sudden shift between (1) a regular respiratory pattern with moderate chest excursion and (2) apneic episodes interspersed with single, deep breaths. This latter pattern was associated with large, low frequency fluctuations in BP. Continued development of the rat conditioning paradigm is especially warranted because of the ability to record sympathetic nerve activity in intact, awake subjects and the large number of readily available genetic strains, which model human pathological states.     

Race,Religion, and Black Lives Matter: Assessing the Association between Sermon Content and Racial Justice Attitudes and Behaviors

We use the 2020/2021 National Politics Study to examine two central questions: 1. How do religious beliefs and clergy sermons about race associate with support for Black Lives Matter (BLM) and racial justice work? And 2. Is the relationship between religion and BLM-related attitudes and activism similar or different across race groups? We found the following: In the months following the summer of 2020 protests in response to George Floyd's murder, African, Hispanic, and White American worship goers who heard sermons about race and policing were more likely than were their co-ethnics to approve of BLM and to engage in racial justice work. Identifying with the religious left and believing that social justice is a core part of one's religaious beliefs is also associated with these groups approving of BLM and engaging in racial justice work. That said, race matters. These forms of religion tend to maintain stronger relationships with White BLM-related attitudes and activism than they do for African Americans and Hispanics.     

Orbitofrontal cortex and dynamic filtering of emotional stimuli

Event-related potentials (ER) were recorded in response to mildly aversive somatosensory and auditory stimuli. Patients with orbitofrontal lesions exhited enhanced ERPs (i.e., P3 amplitudes), as compared with control subjects. Moreover, these patients did not habituate to somatoensory stimuli across blocks of trials. The results were specific to orbitofrontal damage, since patients with damage to the dorsolateral prefontal cortex did not exhibit enhanced P3 amplitudes. These findings suggest damage to the orbitofrontal cortex impairs the ability to modulate or inhibit neural responses to aversive stimuli. The findings are couched in terms of dynamic filtering theory, which suggests that the orbitofrontal cortex is involved in the selection and active inhibition of neural circuits associated with emotional responses.     

Effects of domain knowledge,working memory capacity,and age on cognitive performance: an investigation of the knowledge-is-power hypothesis

Domain knowledge facilitates performance in many cognitive tasks. However, very little is known about the interplay between domain knowledge and factors that are believed to reflect general, and relatively stable, characteristics of the individual. The primary goal of this study was to investigate the interplay between domain knowledge and one such factor: working memory capacity. Adults from wide ranges of working memory capacity, age, and knowledge about the game of baseball listened to, and then answered questions about, simulated radio broadcasts of baseball games. There was a strong facilitative effect of preexisting knowledge of baseball on memory performance, particularly for information judged to be directly relevant to the baseball games. However, there was a positive effect of working memory capacity on memory performance as well, and there was no indication that domain knowledge attenuated this effect. That is, working memory capacity contributed to memory performance even at high levels of domain knowledge. Similarly, there was no evidence that domain knowledge attenuated age-related differences (favoring young adults) in memory performance. We discuss implications of the results for understanding proficiency in cognitive domains from an individual-differences perspective.
