The relationship between psychoanalysis and schizophrenia-A response to the commentary by Robert Michels

In this section, the author responds to Dr Michels's commentary. In contrast to the situation in the United States, there are far fewer psychoanalysts in the UK and very few indeed working in general psychiatry to influence its practice. It is argued that psychoanalysis differs from all other psychological approaches with its recognition of the inner world and its unconscious influence on the individual's everyday life. Michels invites one to focus on outcome studies to judge the effectiveness of psychoanalysis in schizophrenia. There is a danger of throwing the baby out with the bathwater in that psychoanalysis helps in understanding presenting clinical material and in risk assessment in everyday general psychiatry.     

Power and Sample Size Calculations for Contrast Analysis in ANCOVA

Analysis of covariance (ANCOVA) is commonly used in behavioral and educational research to reduce the error variance and improve the power of analysis of variance by adjusting the covariate effects. For planning and evaluating randomized ANCOVA designs, a simple sample-size formula has been proposed to account for the variance deflation factor in the comparison of two treatment groups. The objective of this article is to highlight an overlooked and potential problem of the exiting approximation and to provide an alternative and exact solution of power and sample size assessments for testing treatment contrasts. Numerical investigations are conducted to reveal the relative performance of the two procedures as a reliable technique to accommodate the covariate features that make ANCOVA design particularly distinctive. The described approach has important advantages over the current method in general applicability, methodological justification, and overall accuracy. To enhance the practical usefulness, computer algorithms are presented to implement the recommended power calculations and sample-size determinations.

Nice Guys Finish Fast and Bad Guys Finish Last: Facilitatory vs. Inhibitory Interaction in Parallel Systems

Systems Factorial Technology is a powerful framework for investigating the fundamental properties of human information processing such as architecture (i.e., serial or parallel processing) and capacity (how processing efficiency is affected by increased workload). The Survivor Interaction Contrast (SIC) and the Capacity Coefficient are effective measures in determining these underlying properties, based on response-time data. Each of the different architectures, under the assumption of independent processing, predicts a specific form of the SIC along with some range of capacity. In this study, we explored SIC predictions of discrete-state (Markov process) and continuous-state (Linear Dynamic) models that allow for certain types of cross-channel interaction. The interaction can be facilitatory or inhibitory: one channel can either facilitate, or slow down processing in its counterpart. Despite the relative generality of these models, the combination of the architecture oriented plus the capacity oriented analyses provide for precise identification of the underlying system.     

Scaling relative incentive value in consummatory behavior

Surprising downshifts from more preferred (training incentive) to less preferred incentives (test incentive) are usually accompanied by emotional activation and suppression of conditioned behavior in rats. Two experiments were designed to determine whether consummatory behavior is similarly affected by downshifts of equal proportions. Within limits, the degree of consummatory responding during incentive downshift was similar with equal ratios of test concentration to training concentration. Thus, 32–4% and 16–2% downshifts (1:8 test/training ratios) caused similar levels of consummatory behavior, despite differences in the absolute concentrations of the solutions involved in the downshift. An interpretation based on sensory contrast was discarded because of the long intervals between training and test solutions (40 min and 24 h in Experiments 1 and 2, respectively). It is suggested that Weber’s law regulates behavioral suppression after reward downshifts. A theoretical framework for the interpretation of these data is presented.

Contrast and Assimilation Processes in Consumers' Evaluations of Dual Brands

This study extends the branding literature by examining the psychological processes by which consumers evaluate brand alliances. The theoretical basis for this study is the development of models of context effects in brand evaluations (Meyers-Levy & Sternthal 1993 and Levin & Levin 2000). Of particular interest is how dual branding (two restaurant brands with shared features) influences transfer of affect between brands. Although there was a contrast effect in both the separate and dual brand conditions, this contrast effect was significantly reduced in the dual brand condition. Marketing implications of forming brand alliances are discussed.     

Asynchronous perception of motion and luminance change

Observers were asked to indicate when a target moving on a circular trajectory changed its luminance. The judged position of the luminance change was displaced from the true position in the direction of motion, indicating differences between the times-to-consciousness of motion and luminance change. Motion was processed faster than luminance change. The latency difference was more pronounced for a small (116–134 ms) than for a large luminance decrement (37 ms). The results show that first-order motion is perceived before an accurate representation of luminance is available. These findings are consistent with current accounts of the flash-lag effect. Two control experiments ruled out that the results were due to a general forward tendency. Localization of the target when an auditory signal was presented did not produce forward displacement, and the judged onset of motion was not shifted in the direction of motion.     

Progressing from programmatic to discovery research: a case example with the overjustification effect

Scientific research progresses along planned (programmatic research) and unplanned (discovery research) paths. In the current investigation, we attempted to conduct a single-case evaluation of the overjustification effect (i.e., programmatic research). Results of the initial analysis were contrary to the overjustification hypothesis in that removal of the reward contingency produced an increase in responding. Based on this unexpected finding, we conducted subsequent analyses to further evaluate the mechanisms underlying these results (i.e., discovery research). Results of the additional analyses suggested that the reward contingency functioned as punishment (because the participant preferred the task to the rewards) and that withdrawal of the contingency produced punishment contrast.     

Against the odds: human values arising in unfavourable circumstances elicit the feeling of being moved

People sometimes say they are “moved” or “touched” by something. Although the experience is familiar to most, systematic research on being moved has just begun. The current research aims to advance our understanding of the prototypical elicitors of being moved. We tested the hypothesis that being moved is elicited by core values (i.e. values that are particularly central to being human) that manifest themselves in circumstances that are unfavourable to their emergence. In three experiments, two with text stimuli and one with pictorial stimuli, we found compelling evidence that the same core value (e.g. love, willpower, beauty) is perceived as more moving when it emerges in unfavourable than in favourable circumstances. The effect was found in both males and females, although stronger in the latter group, and across all investigated core values, although love was generally more moving than other core values. The theoretical and practical significance of these findings is discussed.
