Giving and sharing in the computer‐mediated economy

The paper examines how digital technology mediates the behaviour of consumers in three online systems that facilitate offline gift giving and sharing (Freecycle, Couchsurfing, and Landshare). Findings derived from a netnography and depth interviews reveal how technology is used to enact and influence the management of identity, partner selection, ritual normalisation, and negotiation of property rights. The findings have significant implications for the design and management of systems that encourage non‐monetary forms of collaborative consumption. Copyright © 2014 John Wiley & Sons, Ltd.     

Uses of guilt in the treatment of dehumanization

It is likely that under the impact of impending Nazism, aggression theory in late Freud, as presented in Civilization and its Discontents (1930), left the entirety of guilt to self‐punishment, thus retracting his view that love functions in the superego as remorse and restitution. This change however, essentially withdraws provision for treating victims of abuse, violence and terror. This paper proposes a paradigm shift that reframes Freud's late instinct theory into a theory of dehumanization by recovering reparative and relational components of guilt. This reframe has major implications for the position taken with regard to the role of witnessing and the moral imperative in recovery from dehumanizing experience, which orthodox psychoanalytic theory has essentially bypassed. It is propose that victim treatment, as case examples illustrate, reformulates guilt as drawing on the life instincts to revivify victims’ humanity through analytic witnessing and acknowledgment. Indeed, unless breaches of humanity are confronted by a witness, the life instincts stay merely rhetorical, if not contradictory, by leaving the death instincts to grow unseen and, thus, unopposed. A two‐fold formulation of guilt may better address and redress disorders of dehumanization, whereby ‘death guilt’ (under the sway of aggression) signifies the orthodox, irrevocable guilt of self‐reproach for the bad we may have done, and ‘life guilt’ (under the sway of a moral imperative) the redeemable guilt for the good we have still to do.     

What's Context Got to Do with It? Comparative Difficulty of Test Questions Influences Metacognition and Corrected Scores for Formula‐scored Exams

Summary: On formula‐scored exams students receive points and penalties for correct and incorrect answers, respectively, but they can avoid the penalty by withholding incorrect answers. However, test‐takers have difficulty strategically regulating their accuracy and often set an overly conservative metacognitive response bias (e.g., Higham, 2007). The current experiments extended these findings by exploring whether the comparative difficulty of surrounding test questions (i.e., easy vs. hard)—a factor unrelated to the knowledge being tested—impacts metacognitive response bias for medium‐difficulty test questions. Comparative difficulty had no significant influence on participants' ability to choose correct answers for medium questions, but it did affect willingness to report answers and confidence ratings. This difference carried over to corrected scores (scores after penalties are applied) when comparative difficulty was manipulated within‐subjects: Scores were higher in the hard condition. Results are discussed in terms of implications for interpreting formula‐scored tests and underlying mechanisms of performance.Copyright © 2017 John Wiley & Sons, Ltd.     

The effect of spatial frequency information and visual similarity in threat detection

In the current research, we sought to examine the role of spatial frequency on the detection of threat using a speeded visual search paradigm. Participants searched for threat-relevant (snakes or spiders) or non-threat-relevant (frogs or cockroaches) targets in an array of neutral (flowers or mushrooms) distracters, and we measured search performance with images filtered to contain different levels (high and low) of spatial frequency information. The results replicate previous work demonstrating more rapid detection of threatening versus non-threatening stimuli [e.g. LoBue, V. & DeLoache, J. S. (2008). Detecting the snake in the grass: Attention to fear-relevant stimuli by adults and young children. Psychological Science, 19, 284–289. doi:10.1111/j.1467-9280.2008.02081.x]. Most importantly, the results suggest that low spatial frequency or relatively coarse levels of visual information is sufficient for the rapid and accurate detection of threatening stimuli. Furthermore, the results also suggest that visual similarity between the stimuli used in the search tasks plays a significant role in speeded detection. The results are discussed in terms of the theoretical implications for the rapid detection of threat and methodological implications for properly accounting for similarity between the stimuli in visual search studies.
