Recurrence of phonetic responding

This study determined if previously reinforced academic responding recurred when alternative responses were differentially reinforced and subsequently placed on extinction, and whether the magnitude of resurgence was related to the rate of differential reinforcement for the alternative behavior. Three kindergarten students read Greek letters aloud as arbitrary consonant–vowel blends. Resurgence was reliably demonstrated within and across participants, and the magnitude of resurgence was related to the prior rate of differential reinforcement of alternative behavior.     

Poison-drinking in obedience to the faith: a phenomenological study of the experience

In Appalachia, there are certain Christian sects who handle venomous serpents in their church services. Although their serpent handling has received some attention, another of their practices, poison-drinking, has all but escaped the concern of investigators. Addressing this issue, this study included phenomenological interviews with seven believers who ingested strychnine at church. A hermeneutic analysis of their transcribed interviews discovered four major themes that emerged across all protocols to describe the structure of meaning in the experience of poison-drinking: (1) Desire to Drink; (2) “God Moving on Me” (in terms of Anointing and “Insurance” against Harm); (3) Already “Snake Bit”; and (4) “Victory”/“Devil Troubling My Mind”. These interdependent themes are discussed in relation to the existential grounds of body, others, time, and world.     

Retrieval failure versus memory loss in experimental amnesia: definitions and processes

For at least 40 years, there has been a recurring argument concerning the nature of experimental amnesia, with one side arguing that amnesic treatments interfere with the formation of enduring memories and the other side arguing that these treatments interfere with the expression of memories that were effectively encoded. The argument appears to stem from a combination of (1) unclear definitions and (2) real differences in the theoretical vantages that underlie the interpretation of relevant data. Here we speak to how the field might avoid arguments that are definitional in nature and how various hypotheses fare in light of published data. Existing but often overlooked data favor very rapid (milliseconds) synaptic consolidation, with experimental amnesia reflecting, at least in part, deficits in retrieval rather than in the initial storage of information.     

What's the problem? A response to "secular humanism and scientific psychiatry"

Natural philosophy once spanned the fields of philosophy, science, and medicine. Scientific disciplines and medical specialties have rapidly achieved independence, and the availability of the internet and open-access publishing promises a further expansion of knowledge. Nevertheless, a consideration of the grounding concepts and ethical principles that underlie health care remains paramount. It is timely, therefore, to contribute to the global conversation on health care with an open-access journal that focuses on addressing the conceptual basis of medicine and related disciplines, considering the ethical aspects of clinical practice, and exploring its intersection with the humanities (including history of medicine).     

The priority heuristic: making choices without trade-offs

Bernoulli's framework of expected utility serves as a model for various psychological processes, including motivation, moral sense, attitudes, and decision making. To account for evidence at variance with expected utility, the authors generalize the framework of fast and frugal heuristics from inferences to preferences. The priority heuristic predicts (a) the Allais paradox, (b) risk aversion for gains if probabilities are high, (c) risk seeking for gains if probabilities are low (e.g., lottery tickets), (d) risk aversion for losses if probabilities are low (e.g., buying insurance), (e) risk seeking for losses if probabilities are high, (f) the certainty effect, (g) the possibility effect, and (h) intransitivities. The authors test how accurately the heuristic predicts people's choices, compared with previously proposed heuristics and 3 modifications of expected utility theory: security-potential/aspiration theory, transfer-of-attention-exchange model, and cumulative prospect theory.     

Decisions from experience: Why small samples?

In many decisions we cannot consult explicit statistics telling us about the risks involved in our actions. In lieu of such data, we can arrive at an understanding of our dicey options by sampling from them. The size of the samples that we take determines, ceteris paribus, how good our choices will be. Studies of decisions from experience have observed that people tend to rely on relatively small samples from payoff distributions, and small samples are at times rendered even smaller because of recency. We suggest one contributing and previously unnoticed reason for reliance on frugal search: Small samples amplify the difference between the expected earnings associated with the payoff distributions, thus making the options more distinct and choice easier. We describe the magnitude of this amplification effect, and the potential costs that it exacts, and we empirically test four of its implications.     

A review of the profile of mood states (POMS) in the prediction of athletic success

Abstract

The Profile of Mood States (POMS) is a self-report inventory that has been used by numerous researchers attempting to identify the personality states that reliably differentiate athletes of differing levels of ability. The paper began by reviewing the studies by Nagle, Morgan, Hellichn, serfass, and Alexander (1975). Morgan and Pollock (1977), and Morgan and Johnson (1978). These studies popularized the use of the POMS in the sport setting The review highlighted the fact that the POMS was orighally employed as one of several psychological inventories desighed to assess an athlete's state of mental health. Specifically, these studies hypothesized that successfid athletes would possess more positive emotional and mental health than unsuccessfid athletes. With respect to the POMS this would be reflected by successful athletes scoring lower than unsuccessfid athletes on the scales of depression, tension, anger, fatigue, and confusion and higher than unsuccessful athletes on the scale of vigor. The POMS was found to be of limited value in diffkreutiating the successll from unsuccessful athlete. Despite this fact, studies Continued to be published that examined the POMS' ability to diffrrentiate athletes of diffenhg levels of ability. This misunderstanding is attributed to researchers' Mure to distinguish between two common approaches to the study of entiate a) the athlete from the nonathlete and, b) athletes of differing levels of ability. The Profile of Mood States (POMS) is a self-report inventory that has been used by numerous researchers attempting to identify the personality states that reliably differentiate athletes of differing levels of ability.
