Caricature and face recognition

Although caricatures are often gross distortions of faces, they frequently appear to be super-portraits capable of eliciting recognition better than veridical depictions. This may occur because faces are encoded as distinctive feature deviations from a prototype. The exaggeration of these deviations in a caricature may enhance recognition because it emphasizes the features of the face that are encoded. In two experiments, we tested the superportrait hypothesis and the encoding-by-caricature hypothesis. In the first experiment, caricatures were recognized better than faces, and true caricatures of previously seen faces were recognized better than the faces from which the caricatures had been developed. In the second experiment, faces and their caricatures were tachistoscopically presented in a sequential same/different reaction time task. Subjects were slower to distinguish the stimuli when the face preceded its caricature, indicating that caricatures are more similar to the encoded representation of a face than are stimuli in which the distinctive features are deemphasized.     

Choice in a self-control paradigm: Quantification of experience-based differences

Previous quantitative models of choice in a self-control paradigm (choice between a larger, more-delayed reinforcer and a smaller, less-delayed reinforcer) have not described individual differences. Two experiments are reported that provide additional quantitative data on experience-based differences in choice between reinforcers of varying sizes and delays. In Experiment 1, seven pigeons in a self-control paradigm were exposed to a fading procedure that increased choices of the larger, more-delayed reinforcer through gradually decreasing the delay to the smaller of two equally delayed reinforcers. Three control subjects, exposed to each of the small-reinforcer delays to which the experimental subjects were exposed, but for fewer sessions, demonstrated that lengthy exposure to each of the conditions in the fading procedure may be necessary in order for the increase to occur. In Experiment 2, pigeons with and without fading-procedure exposure chose between reinforcers of varying sizes and delays scheduled according to a concurrent variable-interval variable-interval schedule. In both experiments, pigeons with fading-procedure exposure were more sensitive to variations in reinforcer size than reinforcer delay when compared with pigeons without this exposure. The data were described by the generalized matching law when the relative size of its exponents, representing subjects' relative sensitivity to reinforcer size and delay, were grouped according to subjects' experience.

Serial dependence promotes the stability of perceived emotional expression depending on face similarity

Individuals can quickly and effortlessly recognize facial expressions, which is critical for social perception and emotion regulation. This sensitivity to even slight facial changes could result in unstable percepts of an individual’s expression over time. The visual system must therefore balance accuracy with maintaining perceptual stability. However, previous research has focused on our sensitivity to changing expressions, and the mechanism behind expression stability remains an open question. Recent results demonstrate that perception of facial identity is systematically biased toward recently seen visual input. This positive perceptual pull, or serial dependence, may help stabilize perceived expression. To test this, observers judged random facial expression morphs ranging from happy to sad to angry. We found a pull in perceived expression toward previously seen expressions, but only when the 1-back and current face had similar identities. Our results are consistent with the existence of the continuity field for expression, a specialized mechanism that promotes the stability of emotion perception, which could help facilitate social interactions and emotion regulation.     

Instructions for Climbing the Ladder (The Minimalism of Wittgenstein's Tractatus)

I aim to present a solution to the apparent paradox of the Tractatus by means of a minimalist reading grounded in the idea that the correct logical symbolism alone “finally solves” in essentials the philosophical problems. I argue that although the sentences of the Tractatus are nonsensical, rules presented in its symbolism are not. The symbolism itself expresses only a priori rules of logic through schematic variables that do not say anything. I argue that this reading correctly expresses the ladder structure of the book, and that it can account for Wittgenstein's critique of the Tractatus in Some Remarks on Logical Form.     

Procrastination as self‐regulation failure of performance: effects of cognitive load,self‐awareness,and time limits on ‘working best under pressure’

Effects of cognitive load, objective self‐awareness and time limits on the self‐regulation of performance speed and accuracy were investigated between procrastinators and non‐procrastinators. In experiment 1 chronic procrastinators completed fewer items (slow speed) and made more errors (less accuracy) than non‐procrastinators under high but not low cognitive load conditions when the time span was limited and brief. In experiment 2 chronic procrastinators performed slower than non‐procrastinators under a 2 second, but not under no limit, 1 second, or 4 second time limit conditions. Chronic procrastinators compared to non‐procrastinators also performed more slowly and made more performance errors under objective self‐awareness conditions regardless of the length of time. These experiments indicate that chronic procrastinators regulate ineffectively their performance speed and accuracy when they ‘work under pressure’ (defined by high cognitive load, objective self‐awareness, and imposed time limitations).

Getting stuck or stepping back: Effects of obstacles and construal level in the negotiation of creative solutions

Difficult issues in negotiation act as interfering forces but their effects on negotiation processes and outcomes are unclear. Perhaps facing such obstacles leads individuals to take a step back, attend to the big picture and, therefore, to be able to craft creative, mutually beneficial solutions. Alternatively, facing obstacles may lead negotiators to focus narrowly on the obstacle issue, so that they no longer consider issues simultaneously, and forego the possibility to reach high quality, integrative agreements. Three experiments involving face-to-face negotiation support the “getting stuck” hypothesis, but only when negotiators are in a local processing mode and not when they are in a global processing mode. Implications for the art and science of negotiation, and for construal level theory, are discussed.     

Weight Bias Internalization Scale Discriminates Obese and Overweight Patients with Different Severity Levels of Depression: the Italian Version of the WBIS

We have investigated the psychometric properties of the Italian version of the weight bias internalization scale (WBIS) in overweight and obese patients who were attending weight loss programs. Participants were 386 overweight and obese patients admitted in two medical centers specializing in the treatment of obesity. All the patients were administered the WBIS, and measures of binge eating, depression, self-esteem, and body dissatisfaction. Confirmatory factor analysis failed to confirm the fit of the original 11-item unidimensional model. Item analysis and exploratory factor analysis indicated that 9 items included in the original measure (the items 1 and 9 were excluded because low item-total correlations) formed a reliable unidimensional measure of internalized weight bias (WBIS-9). The WBIS-9 was significantly correlated with convergent measures and was able to categorize individuals with different severity levels of depression (sensitivity of 0.72 and specificity of 0.70). The WBIS-9 may be useful in clinical practice to discriminate patients with more severe psychopathology, comorbid disordered eating patterns, and risk for poor outcomes.     

The effectiveness of university counselling for improving academic outcomes and well-being

The work discusses the effectiveness of the counselling treatment to enhance student academic success. The participants were randomly assigned to either an experimental group (66 students who had completed counselling treatment) or a wait-list comparison group (44 students). The Adult Self Report (ASR) by Achenbach and Rescorla [2003. Manual for the ASEBA adult forms & profiles. Burlington, VT: Research Center for Children, Youth, & Families, University of Vermont] and the Outcome Questionnaire 45 (OQ-45) by Lambert and Hill [1994. Assessing psychotherapy outcomes and processes. In A. E. Bergin & S. L. Garfield (Eds.), Handbook of psychotherapy and behavior change (pp. 72–113). New York: John Wiley] were applied before and after the counselling sessions. Data show statistically significant decrease in the ASR clinical scales for both internalising and externalising problems after counselling as well as in the OQ-45 scores for distress symptoms and relationship difficulties. Compared with the control group, the students who received counselling exhibited a significant recovery regarding their progress with their studies.
