Adult age differences in elaborations produced during prose recall

This study focused on adult age differences in the characteristics and quantity of elaborations produced during a prose recall task. Young (M = 24.3 years) and older (M = 67.9 years) adults were tested in 3 same-age, same-gender group size conditions: individual, dyad, and tetrad. Elaborations, which are statements not contained in the text but not inconsistent with it, were divided into 2 major categories. Denotative elaborations included statements that were closely related to the text and filled in gaps in the stories. These elaborations were equally produced by young and older adults and were significantly correlated with gist recall performance. Annotative elaborations were evaluative and interpretive comments. These statements were more frequently produced by older adults but were not correlated with recall performance. Young and older adults had different patterns of annotative elaboration production across group size conditions.     

Computers and computing in psychology: Twenty years of progress and still a bright future

Computers and technology in psychology can be a cornucopia or a Pandora’s box. During the 20 years of its existence, the Society for Computers in Psychology has been an important focus for the appropriate and beneficial application of computing technology in psychology. Although the increase of computer use is unmistakable, cyclic trends in computer applications also can be identified and, together with current technological developments, lead to predictions, concerns, and challenges for the future.     

A sensory contact model for the study of aggressive and submissive behavior in male mice

The technique for simultaneous development of aggressive and submissive behaviors as a result of successive experiences of defeats or victories in daily intermale confrontations in male mice permanently living under sensory contact conditions is offered for behavioral, pharmacological, and neurophysiological studies of mechanisms of agonistic social relations. Distant sensory contact is achieved by placing a pair of males into a common cage separated by a transparent partition with holes permitting visual contact and the individuals perceiving each other's odors but preventing any physical at contact all times except for 10-min daily tests. These conditions essentially elicit aggression in winner males and quickly result in submission by losers of the same strain of mice. The meaning of consecutive stages of the technique, the problem of controls, and applications of this model are discussed.     

Psychoanalysis as science: the inductivist's resistance revisited

The scientific status of psychoanalysis has been the focus of heated debates among philosophers of science and among psychoanalysts. The most recent challenge to psychoanalysis as a science comes from the quarters of the inductivist philosophy of science. Since inductivism is a self-defeating philosophy, it is not surprising that inductivists demand that psychoanalysts pay an unlimited price for their claim of scientific status for psychoanalysis. Most psychoanalysts, in their response to this impossible challenge, unwittingly claim to have paid the price. What is worse, the claim is made in a confused and emotionally charged manner. Hence, psychoanalysts are usually defensive and, thus, in error when repelling (in this way) the attack of the inductivist philosopher. It is not psychoanalysis inductivists attack, but their own commitment to their own logic which leads inexorably to the dissolution of their argument, of all science, and, indeed, of psychoanalysis as well. It seems much more reasonable to postpone any response to the challenges that confront psychoanalysis today and to invest effort in a reformulation of the problem of the scientific status of psychoanalysis. Different rational solutions to the problem may evolve if we take care to become well informed first about the limits of our theoretical frameworks and show readiness to change them, if and when needed. That is to say, we can start with a somewhat tentative, not to say skeptical, frame of mind concerning the very concept of scientific status. We may try to keep and to contain our skepticism to the degree required by the discourse at hand, carry on exploring in our practice, report our results, and discuss them respectfully. We should start by admitting that, quite possibly, our discourse will end inconclusively.     

Infants' enumeration of actions: numerical discrimination and its signature limits

Are abstract representations of number – representations that are independent of the particular type of entities that are enumerated – a product of human language or culture, or do they trace back to human infancy? To address this question, four experiments investigated whether human infants discriminate between sequences of actions (jumps of a puppet) on the basis of numerosity. At 6 months, infants successfully discriminated four‐ versus eight‐jump sequences, when the continuous variables of sequence duration, jump duration, jump rate, jump interval and duration, and extent of motion were controlled, and rhythm was eliminated. In contrast, infants failed to discriminate two‐ versus four‐jump sequences, suggesting that infants fail to form cardinal number representations of small numbers of actions. Infants also failed to discriminate between sequences of four versus six jumps at 6 months, and succeeded at 9 months, suggesting that infants’ number representations are imprecise and increase in precision with age. All of these findings agree with those of studies using visual–spatial arrays and auditory sequences, providing evidence that a single, abstract system of number representation is present and functional in infancy.     

The atheist’s free will offence

This paper criticizes the assumption,omnipresent in contemporary philosophy ofreligion, that a perfectly good and loving Godwould wish to confer on (at least some) finitepersons free will. An alternative mode ofDivine-human relationship is introduced andshown to be as conducive to the realization ofvalue as one involving free will.Certain implications of this result are thenrevealed, to wit, that the theists free willdefence against the problem of evil isunsuccessful, and what is more, that free will,if it exists, provides positive support foratheism.     

The Physical Appearance Ambiguous Feedback Scale (PAAFS): a measure for indexing body image related cognitive bias

Recent conceptualizations of body image disturbance have included an information processing model that includes a focus on an interpretive information processing bias. Study 1 involved the development and validation of a measure of appearance-based cognitive bias, the Physical Appearance Ambiguous Feedback Scale (PAAFS). In Studies 2 and 3, two samples of college females (n=313) were tested and the psychometric characteristics of the PAAFS were evaluated. Reliability was acceptable and convergence with measures of body image and eating disturbance was moderate. In Study 4, 313 college females completed the PAAFS in the laboratory based on an instructional content designed to induce processing bias. Preliminary evidence indicates that the PAAFS appears to be sensitive to instructional set manipulations and dispositional level of body dissatisfaction.
