Voluntary action alters the perception of visual illusions

Attention, Perception, & Psychophysics - “Intentional binding” refers to the finding that people judge voluntary actions and their effects as having occurred closer together in time...     

Self-reported parental abuse relates to autobiographical memory style in patients with eating disorders

Previous research has shown a relationship between levels of self-reported childhood abuse and overgeneral memory style. This relationship was further clarified in patients with an eating disorder (ED). Patients and healthy controls completed a task in which they had to generate specific autobiographical memories to emotional cue words. The results showed that first, the ED group, relative to the controls, produced more first memories that were "overgeneral" and fewer first memories that were specific. Second, in the ED group, the level of self-reported parental abuse was positively correlated with the tendency to produce overgeneral memories to negative cues. This effect remained significant even after levels of depressed mood were controlled for.     

Graduate Pre-Selection: Some Findings and their Guidance Implications

The application forms of graduate applicants to six organisations were analysed in two investigations. In the first, those features of the forms which predicted whether they were rejected or passed on for interview were discovered. These differed across organisational type, and included aspects of the way in which the form was completed and personal background factors, as well as experience and achievement. In the second investigation, the think-aloud protocols of recruiters as they read the application forms were analysed. Inferences from information rather than the information itself predicted decisions. It is concluded that careers advisers should offer instruction on a variety of matters relating to completion of application forms; and that graduate recruiters should continue to undertake the task of pre selection rather than seeking to 'farm it out'.     

Processing the facial image: a brief history

The study of the neural basis of face perception is a major research interest today. This review traces its roots in monkey neuropsychology and neurophysiology beginning with the Klüver-Bucy syndrome and its fractionation and then continuing with lesion and single neuron recording studies of inferior temporal cortex. The context and consequence of the discovery of inferior temporal neurons selective for faces is described and current lines of research on inferior temporal cortex and face processing in both monkeys and humans are outlined.     

MMPI-2 personality profiles of high-functioning adults with autism spectrum disorders

The Minnesota Multiphasic Personality Inventory-Second Edition was administered to 20 adults with autism spectrum disorders (ASD) who fell in the average to above average range of intelligence and 24 age-, intelligence-, and gender-matched college students. Large group differences, with the ASD group scoring higher, were found on the L validity scale, Clinical Scales 2 (D) and 0 (Si), Content scale Social Discomfort (SOD), Supplementary scale Repression (R), and Personality Psychopathology Five (PSY-5) scale INTR (Introversion). The proportion of ASD adults scoring in the clinical range on these scales was between 25% and 35%. High scores on these scales are consistent with the clinical picture of Asperger syndrome and high-functioning autism in adulthood. Future directions and implications for identifying adults in need of a specialized autism assessment are discussed.     

Opinion formation in evaluating sanity at the time of the offense: an examination of 5175 pre-trial evaluations

Sanity evaluations are high-stake undertakings that explicitly examine the defendant's culpability for a crime and implicitly explore clinical information that might inform a plea agreement. Despite the gravity of such evaluations, relatively little research has investigated the process by which evaluators form their psycholegal opinions. In the current study, we explore this process by examining 5175 sanity evaluations conducted by a cohort of forensic evaluators in Virginia over a ten-year period. Our analyses focus on (i) the clinical, criminal, and demographic attributes of the defendant correlated with opinions indicative of insanity; (ii) the clinical content of the evaluations and the legal criteria referenced as the basis for the psycholegal opinion; (iii) the process and outcome differences in the sanity evaluations conducted by psychologists versus psychiatrists; and (iv) the consistency in these opinions over a ten year period. Analyses predicting an opinion of insanity indicate a positive relationship with psychotic, organic, and affective diagnoses and previous psychiatric treatment. Analyses also indicate a negative relationship with prior criminal history, drug charges, personality disorder diagnosis, and intoxication at the time of the offense. Modest racial disparities were observed with evaluators offering opinions that the defendant was insane more often for white than for minority defendants despite comparable psychiatric and criminal characteristics.     

The rich get richer: Students’ discounting of hypothetical delayed rewards and real effortful extra credit

The present research compared choices among students with higher or lower grades for rewards that were devalued by imposing a delay to their receipt (Study 1) or by requiring more work for a larger reward (Study 2). In Study 1, students chose between hypothetical and noncontingent smaller immediate or larger delayed monetary rewards. In Study 2, students chose from among different amounts of real, response-contingent academic rewards (extra credit) that required different amounts of work. The results of both studies were similar: The highest scoring students discounted the value of the delayed money less than did their lower scoring counterparts, and the highest scoring students also chose to do and actually did more extra-credit work than lower scoring students did. Differences in the discounting of devalued rewards might represent a fundamental difference between the highest and lower scoring students.     

The effects of accountability on bias in physician decision making: Going from bad to worse

Members of the Iowa Academy of Family Physicians participated in a survey study in which they were asked to make hypothetical decisions in either high- or low-conflict treatment conditions. In the low-conflict treatment condition the options were a common medication with a referral or a referral only. In the high-conflict treatment condition the same two options were given plus another attractive medication. In addition, we manipulated accountability by asking half of the participants to provide a written defense of their treatment options, which they would then agree to discuss at a later time. The results showed that physicians in the high-conflict condition chose the referral-only option significantly more than the physicians in the low-conflict condition, thus violating the normative rule of regularity. Moreover, that pattern was significantly amplified for physicians who were held accountable for their treatment decisions. These findings replicate and extend previous research and are discussed within the framework of reason-based choice.     

How the brain blinks: towards a neurocognitive model of the attentional blink

When people monitor a visual stream of rapidly presented stimuli for two targets (T1 and T2), they often miss T2 if it falls into a time window of about half a second after T1 onset-the attentional blink (AB). We provide an overview of recent neuroscientific studies devoted to analyze the neural processes underlying the AB and their temporal dynamics. The available evidence points to an attentional network involving temporal, right-parietal and frontal cortex, and suggests that the components of this neural network interact by means of synchronization and stimulus-induced desynchronization in the beta frequency range. We set up a neurocognitive scenario describing how the AB might emerge and why it depends on the presence of masks and the other event(s) the targets are embedded in. The scenario supports the idea that the AB arises from "biased competition", with the top-down bias being generated by parietal-frontal interactions and the competition taking place between stimulus codes in temporal cortex.
