Flicker thresholds as determined by a modified conditioned suppression procedure,

Critical flicker fusion frequencies were determined as a function of stimulus intensity for three White Carneaux pigeons using a modified conditioned suppression paradigm as a threshold procedure. Critical frequencies ranged from 6 cps for the lowest intensity of 0.0014 ml to 77 cps for the maximum intensity of 41.86 ml.     

A limited population of unmarried adolescent fathers: a preliminary report of their views on fatherhood and the relationship with the mothers of their children

Although much has been documented regarding adolescent childbearing (Juhasz, 1974; Furstenburg, 1976; Card & Wise, 1978; Russ-eft, 1979; Chilman, 1980; Earl & Siegel, 1980), little is known about the attitudes of unmarried adolescent fathers toward fatherhood and their relationship with the mothers of their children. Most of what is known about this relationship has been learned from the young mothers (Sauber, 1966; Bernstein, 1971; Pope, 1971; bemis, 1976; Lorenzi, 1977; Clapp & Raab, 1978). With the exception of a few investigators (Pannor et al., 1968; Pannor, 1971, Hendricks, 1981), virtually no accounts can be found in the literature documenting unmarried adolescent fathers' perceptions of fatherhood and their relationship with the mothers of their children. This paper attempts to bridge this gap in the literature by reporting on how two select populations of black unmarried adolescent fathers view fatherhood and their relationship with the mothers of their children.     

A beautiful day in the neighborhood: What factors determine the generation effect for simple multiplication problems?

In four experiments, we examined the generation effect for the free recall of simple multiplication answers. Large-product-size problems showed a consistent generation-effect advantage over small-product-size problems, except when each answer was generated twice, via two different sets of operands (Experiment 2). Also, measures of problem-solution time and strategy use accounted for the large-product-size advantage. Across experiments, however, small-product-size problems (but not large-product-size problems) showed considerable variation in the size of their generation effect. We discovered that solving small-product-size problems via direct memory retrieval increased the episodic recall probability of other problems that were near neighbors to the generated answer, and we attribute this result to a spreading activation mechanism in semantic memory. A measure of neighbor activations, combined with RT to solve each problem, accounted for 51% of the observed generation-effect variance.     

Psychological consultation under Oregon's 1994 Death With Dignity Act: ethics and procedures

The Oregon 1994 Death With Dignity Act prescribes an evaluation by a psychologist or psychiatrist when the patient is suspected to be suffering from impaired judgment. Several attempts have been made to propose procedures for assessing end-of-life mental conditions and competence. The psychologist's role may include ethical considerations, protecting patients' rights to autonomy, ensuring competent judgment, preventing unnecessary suffering and appropriate diagnoses of mental disorders, and supporting family members and the health care team.     

Body schema, gender, and other correlates in nonclinical populations

The link between body image and eating disorders has been extensively discussed, but investigations using nonclinical populations have not been systematically reviewed. In this article, a model to guide future researchers has been provided, and an attempt has been made to organize and synthesize the existing findings, with special attention to gender differences. Future researchers should more carefully delineate behavioral, emotional, cognitive, motivational, and evaluative components of body schema and should explore the relationship between body schema and outcomes other than eating disturbances. Conclusions in this review include the following: (a) Verbal measures of body schema are more successful than visual assessment tools; (b) measures of body distortion have been less successful than measures of dissatisfaction; (c) gender differences are prevalent; (d) behavioral outcomes can be successfully predicted; and (e) pubertal development plays a critical role in the gender differentiation of body schemas.

Sexual Peak: Socially Shared Cognitions About Desire,Frequency, and Satisfaction in Men and Women

Is a man’s sexual peak earlier than a woman’s? Three studies were conducted to examine (a) whether the perception that men achieve their sexual peak at a younger age than do women is shared across individuals of different ages and sexes, (b) whether sexual peak is defined differently for men and women, and (c) whether differences between definitions contribute to differences in the age at which men and women are perceived to reach sexual peak. Study 1 suggested that participants believed that females reach their sexual peak at an older age than do males. Study 2 indicated that the defining feature of sexual peak for males was sexual desire and for females was sexual satisfaction. Study 3 suggested that predictions of male sexual peak coincided with participants’ predictions of male age of highest desire and frequency, but not satisfaction, and that female sexual peak coincided with participants' predictions of female age of highest satisfaction but not frequency or desire. Discussion focuses on potential reasons for differences between the perception of male and female sexuality, as well as the social and evolutionary importance of each of the dimensions of sexuality for both males and females.     

When a Skeptical Hypothesis Is Live

I’m going to argue for a set of restricted skeptical results: roughly put, we don’t know that fire engines are red, we don’t know that we sometimes have pains in our lower backs, we don’t know that John Rawls was kind, and we don’t even know that we believe any of those truths. However, people unfamiliar with philosophy and cognitive science do know all those things. The skeptical argument is traditional in form: here's a skeptical hypothesis; you can’t epistemically neutralize it, you have to be able to neutralize it to know P; so you don’t know P. But the skeptical hypotheses I plug into it are “real, live” scientific‐philosophical hypotheses often thought to be actually true, unlike any of the outrageous traditional skeptical hypotheses (e.g., ‘You’re a brain in a vat’). So I call the resulting skepticism Live Skepticism. Notably, the Live Skeptic's argument goes through even if we adopt the clever anti‐skeptical fixes thought up in recent years such as reliabilism, relevant alternatives theory, contextualism, and the rejection of epistemic closure. Furthermore, the scope of Live Skepticism is bizarre: although we don’t know the simple facts noted above, many of us do know that there are black holes and other amazing facts.
