Response priming driven by local contrast, not subjective brightness

We demonstrate qualitative dissociations of brightness processing in visuomotor priming and conscious vision. Speeded keypress responses to the brighter of two luminance targets were performed in the presence of preceding dark and bright primes (clearly visible and flanking the targets) whose apparent brightness values were enhanced or attenuated by a visual illusion. Response times to the targets were greatly affected by consistent versus inconsistent arrangements of the primes, relative to the targets (response priming). Priming effects could systematically contradict subjective brightness matches, such that one prime could appear brighter than the other but could prime as if it were darker. Systematic variation of the illusion showed that response-priming effects depended only on local flanker-background contrast, not on the subjective appearance of the flankers. Our findings suggest that speeded motor responses, as opposed to conscious perceptual judgments, access an early phase of lightness and brightness processing prior to full lightness constancy.     

The entertainment value of conspiracy theories

Many citizens around the globe believe conspiracy theories. Why are conspiracy theories so appealing? Here, we propose that conspiracy theories elicit intense emotions independent of emotional valence. People therefore find conspiracy theories entertaining – that is, narratives that people perceive as interesting, exciting, and attention-grabbing – and such entertainment appraisals are positively associated with belief in them. Five studies supported these ideas. Participants were exposed to either a conspiratorial or a non-conspiratorial text about the Notre Dame fire (Study 1) or the death of Jeffrey Epstein (preregistered Study 2). The conspiratorial text elicited stronger entertainment appraisals and intense emotions (independent of emotional valence) than the non-conspiratorial text; moreover, entertainment appraisals mediated the effects of the manipulation on conspiracy beliefs. Study 3 indicated that participants endorsed stronger conspiracy beliefs when an election event was described in an entertaining rather than a boring manner. Subsequent findings revealed that both organisational (Study 4) and societal conspiracy beliefs (Study 5) are positively associated with sensation seeking – a trait characterised by a preference for exciting and intense experiences. We conclude that one reason why people believe conspiracy theories is because they find them entertaining.     

Knowledge,beliefs, peer norms,and past behaviors as correlates of risky sexual behaviors among college students

Abstract

HIV/AIDS knowledge, age at onset of sexual activity, perceptions of personal risk and peer norms were explored as correlates for risky sexual behaviors among college students. Ninety-nine male and 185 female college students completed a 66-item questionnaire. A majority reported being sexually active with most in mutually monogamous relationships or not currently in a sexual relationship. Multiple regression correlation analyses showed knowledge about HIV/AIDS to be very high but that this knowledge did not independently relate to the extent of risky behaviors. Perceptions of risk were positively related to number of partners and single-time partners but not condom usage. In contrast to previous studies, perceived peer norms did not independently relate to behaviors. Instead, age at first intercourse was found to have substantial overlap with current perceptions, attitudes, and likelihood for engaging in risky behaviors. The necessity for including previous behaviors in analyses of the impact of attitudes and perceived norms on behavioral intentions is discussed.     

Witness Vetting: What Determines Detectives' Perceptions of Witness Credibility?

During the course of a criminal investigation witness vetting, a detective's process of determining the credibility and weight of witness information, can lead to errors in an investigation that can go virtually unchallenged. Witness confidence, opportunity to view, and type of information proffered were examined in relation to detective inferences about witness reliability, accuracy, and probable cause to arrest. Experiment 1 involved 39 sworn law enforcement officers, and experiment 2 involved 43 sworn law enforcement officers and 86 mock detectives. Participants viewed a digital recording depicting a witness describing a gas station robbery (Experiment 1) or a campus mugging (Experiment 2). Witness confidence and detectives' inferences about culprit information influenced the vetting process and lent credibility to a confident witness whose accuracy was objectively unknown. Furthermore, the evidence indicates that sworn law enforcement are comparable with untrained observers in their use of social inference cues (i.e. confidence) in determining witness credibility; however, social inference can be assuaged by the rational, rule‐governed, decision framework established for witness vetting. Social inference processes inherent in the detective‐witness dyad is influenced by legal procedures in vetting witness information. Copyright © 2013 John Wiley & Sons, Ltd.     

OBSERVATIONAL LEARNING AND THE EMERGENCE OF SYMMETRY RELATIONS IN TEACHING SPANISH VOCABULARY WORDS TO TYPICALLY DEVELOPING CHILDREN

One 9‐year‐old child was taught conditional discriminations between dictated names in Spanish and their corresponding pictures across three stimulus sets while her 10‐year‐old brother observed. Posttests revealed the emergence of symmetry relations in the form of oral naming skills by both children.     

Schwere Anorexia nervosa

Background

Psychosomatic support during acute medical treatment of patients with anorexia nervosa is a special need but up to now a rare constellation. These patients can barely accept necessary somatic procedures even if they suffer from severe consequences of the eating disorder. The ambivalence of patients towards treatment is explained by the loss of the right perception of their bodies and the strong obsession with further weight loss.

Methods

This article reports on eight consecutively treated patients on a medical ward who received a liaison psychosomatic, psychotherapeutic visit twice a week. The aim was to maintain better therapy adherence, to support oral food intake and understanding of the disorder as well as to motivate patients for further psychosomatic treatment.

Results

By means of a respectful cooperation between the departments of internal medicine and psychosomatics it was possible to gain psychotherapeutic access to the patients in this highly complicated situation.

Consequence

The psychodynamic aspects of this collaboration are discussed with a focus on the triangulation of the therapeutic process.     

Bolstering implementation plans for the long haul: the benefits of simultaneously boosting self-concordance or self-efficacy

Recent studies suggest that implementation planning exercises may not be as helpful for long-term, self-initiated goals as for short-term, assigned goals. Two studies used the personal goal paradigm to explore the impact of implementation plans on goal progress over time. Study 1 examined whether administering implementation plans in an autonomy supportive manner would facilitate goal progress relative to a neutral, control condition and a condition in which implementation plans were administered in a controlling manner. Study 2 examined whether combining implementation plans with a self-efficacy boosting exercise would facilitate goal progress relative to a neutral, control condition and a typical implementation condition. The results showed that implementation plans alone did not result in greater goal progress than a neutral condition but that the combination of implementation plans with either autonomy support or self-efficacy boosting resulted in significantly greater goal progress.     

Effects of Personalized Versus Generic Implementation of an Intra-Organizational Online Survey on Psychological Anonymity and Response Behavior: A Field Experiment

Purpose

In the present study, we sought to investigate the effects of online survey implementation strategies on perceived anonymity and employee response behavior in organizational surveys.

Design/Methodology/Approach

A field experiment was conducted to compare two commonly used online survey implementation strategies (N = 815). One group of employees received a personalized invitation to the survey and a log-in password, while the other group received a general invitation and did not have to provide a password.

Findings

The results showed that the applied implementation strategies had no substantial effects on perceived anonymity. Moreover, there were no significant effects on nonresponse or the responses of survey participants to closed-ended and open-ended survey questions.

Implications

The present study supposes that online surveys are not a uniform phenomenon and that differences in the implementation of online surveys need to be considered. However, the findings indicate that the use of specified-personalized implementation strategies does not necessarily lead to a substantial decrease in perceived anonymity or automatically result in reduced data quality. Thus, in many cases, the investigated online survey implementation strategies are unlikely to cause serious reductions in perceptions of anonymity and quality of responses to organizational online surveys.

Originality/Value

In spite of the frequent use of online surveys in organizations, little is known about the consequences of online implementation strategies for perceptions of anonymity and response behavior. This study is one of the few empirical examinations of the psychological consequences of different online implementation strategies frequently used in organizational surveying.
