The Effect of Corporate Social Responsibility (CSR) Activities on Companies With Bad Reputations

Based on theories of attribution and suspicion, three experiments highlight the mediating role of perceived sincerity of motives in determining the effectiveness of CSR activities. CSR activities improve a company's image when consumers attribute sincere motives, are ineffective when sincerity of motives is ambiguous, and hurt the company's image when motives are perceived as insincere. Variables affecting perceived sincerity include the benefit salience of the cause, the source through which consumers learn about CSR, and the ratio of CSR contributions and CSR‐related advertising. High benefit salience of the cause hurts the company, in particular when consumers learn about it from a company source. This backfire effect can be overcome by spending more on CSR activities than on advertising that features CSR.     

The influence of theta transcranial alternating current stimulation (tACS) on working memory storage and processing functions

The study aimed to explore the role of the fronto-parietal brain network in working memory function—in temporary storage and manipulation of information. In a single blind sham controlled experiment 36 respondents solved different working memory tasks after theta transcranial alternating current stimulation (tACS) was applied to left frontal, left parietal and right parietal areas. Both verum tACS protocols stimulating parietal brain areas (target electrodes positioned at location P3, or P4) had a positive effect on WM storage capacity as compared with sham tACS, whereas no such influence was observed for the stimulation of the left frontal area (target electrode positioned at location F3). A second finding was that left parietal theta tACS had a more pronounced influence on backward recall than on forward recall, which was not related to task content (spatial or verbal). The influence of theta tACS on WM executive processes was most pronounced for right parietal stimulation. The results are discussed in the broad theoretical framework of the multicomponent model of working memory.     

Exploring the mental number line: evidence from a dual-task paradigm

In a parity-judgment task smaller numbers are responded to faster with the left-hand key and vice versa for larger numbers (SNARC effect; Dehaene et al., in Journal of Experimental Psychology: General, 122, 371-396, 1993). We used the psychological refractory period paradigm involving a parity-judgment task and tone-discrimination task to address the question at which stage this effect arises. When the parity-judgment task is performed second, then we found equal SNARC effects for the short and the long SOA. According to the central bottleneck model, this indicates that the effect arises during the response-selection or execution stage. In Experiment 2 the parity-judgment task was performed first. The pattern of results indicates that the SNARC effect originates during the perceptual encoding or response-selection. Together, our results suggest that the SNARC effect originates while the response is selected.     

Inferring the popularity of an opinion from its familiarity: a repetitive voice can sound like a chorus

Despite the importance of doing so, people do not always correctly estimate the distribution of opinions within their group. One important mechanism underlying such misjudgments is people's tendency to infer that a familiar opinion is a prevalent one, even when its familiarity derives solely from the repeated expression of 1 group member. Six experiments demonstrate this effect and show that it holds even when perceivers are consciously aware that the opinions come from 1 speaker. The results also indicate that the effect is due to opinion accessibility rather than a conscious inference about the meaning of opinion repetition in a group. Implications for social consensus estimation and social influence are discussed.     

Drogenabhängige Patienten im Maßregelvollzug gemäß § 64 StGB: Verbesserung der Quote erfolgreicher Behandlung durch suchtspezifische Medikation?

In Germany, addicted offenders can be sentenced to compulsory addiction treatment in forensic mental hospital departments (Art. 64 of the penal code). A presupposition to such a sentence is a fair chance of successful treatment and rehabilitation. Commonly, an expert witness is asked by the court to assess this point in the trial. To date, the treatment in forensic mental hospitals aims at total abstinence from any kind of drugs. But in at least half of the cases, a fair chance of successful treatment is no longer seen after a period of therapy. In most cases, these patients are returned to prison. The paper pleads that in offenders addicted to illegal drugs, a drug specific medication – in particular methadone maintenance treatment or naltrexone medication – might be a useful option. The rate of “treatment failure” might be reduced slightly by using this option with some of the patients.     

Is Psychology Based on a Methodological Error?

It is believed a proven fact that variables in social and personality psychology match to normal distribution with its single peak. Multiple peaks are explained by independent variables. However, after a comprehensive data analysis of more than 8.000 patients and on the basis of a bio-psycho-social model with 27 scales, we arrived at the conclusion that normal distribution and the psychometric error theory cannot withstand critical analysis in large samples. Beyond the “truth” that is proved by distribution-dependent statistical inferences, there exists another “truth” that is denied by the empirical doctrine. This “truth” is influenced by compensatory belief systems and explains paradoxes in quality of life research. We hypothesize that items, referred to life risks are micro-stressors, triggering self-regulatory processes as a humanly inherent response, deeply anchored in human evolution. Especially when exposed to threatening experiences, self-focused attention generates amplified multimodal distributions and subverts the methodological premises by an ambivalence-bias between thrill and threat, hopes and fears, pleasure and pain, success and failure, etc. In this article we want to focus attention to the incommensurability between test theoretical axioms and the way people usually respond to self-focused items. We discuss basic distribution patterns and approach to an evolutionary theory of fluctuation of validity.

The advantage of being left-handed in interactive sports

As compared with their prevalence in the general population, left-handers are overrepresented in the expert domain of many interactive sports. This study examined to what extent this is due to negative perceptual frequency effects—that is, whether the greater frequency of tennis matches with right-handed opponents makes it possible to discriminate the stroke movements of right-handed players more precisely. Fifty-four right-handed and 54 left-handed males in three equal-sized groups of varying levels of tennis expertise (national league experts, local league intermediates, and novices) completed a tennis anticipation test in which they had to predict the subsequent direction of an opponent’s temporally occluded tennis strokes on a computer screen. The results showed that all three groups were better at predicting the direction of strokes by right-handed players. This supports the hypothesis that the overrepresentation of left-handers in the expert domain is partly due to perceptual frequency effects.     

If It's Difficult to Pronounce, It Must Be Risky

ABSTRACT— Low processing fluency fosters the impression that a stimulus is unfamiliar, which in turn results in perceptions of higher risk, independent of whether the risk is desirable or undesirable. In Studies 1 and 2, ostensible food additives were rated as more harmful when their names were difficult to pronounce than when their names were easy to pronounce; mediation analyses indicated that this effect was mediated by the perceived novelty of the substance. In Study 3, amusement-park rides were rated as more likely to make one sick (an undesirable risk) and also as more exciting and adventurous (a desirable risk) when their names were difficult to pronounce than when their names were easy to pronounce.
