Role-Playing Computer Ethics: Designing and Evaluating the Privacy by Design (PbD) Simulation

Science and Engineering Ethics - There is growing consensus that teaching computer ethics is important, but there is little consensus on how to do so. One unmet challenge is increasing the capacity...     

Eliciting information and cues to deception using a model statement: Examining the effect of presentation modality

Forensic interviewing involves gathering information from a suspect or eyewitness. Administering a model statement during an interview results in greater information elicitation, which can enhance lie detection. Typically, a model statement is a highly detailed statement, on an unrelated topic to that of the interview. This study examined the effect of manipulating the modality of the MS, either by allowing participants to listen to (Audio‐MS), or read (Written‐MS) a model statement. A total of 162 (81 truth tellers, 81 liars) participants were randomly allocated to one of three interviewing conditions where they received either the Audio‐MS, Written‐MS, or No‐MS (control condition). Truth tellers honestly reported a “spy” mission, whereas liars performed a covert mission and lied about their activities. Results showed both model statements were equally more effective at eliciting information and facilitating lie detection, compared with a control condition. Theoretical and practical implications are discussed.

在西方 ,人们从来没有像今天这样健康、长寿 ,医学的成就也从来没有像今天这样巨大。然而 ,具有讽刺意味的是 ,人们也从来没有像今天这样强烈地对医学产生疑惑和提出批评。毋庸置疑 ,在过去5 0年里医学突破性的进展 ,已挽救了比以往任何时代都要多得多的生命。我们已开始厌倦医学的进步 ,以至于应当对今天认为是当然 ,而一二百年前是不可能的巨大变革进行观察。以下章节将要讨论这些进步。作为导言 ,在这里简要地概括一下在 2 0世纪下半叶发生的重大变化。二战爆发时 ,青霉素仍在实验室研究阶段 ,尚未投入临床应用。在这种抗生素“魔弹”发…     

Olfactory preferences resulting from mere exposure in human neonates

Twenty-four (12 males, 12 females) healthy, full-term neonates were exposed to an artificial odorant within the first day after birth for approximately 24 hrs to determine if mere exposure would lead to a subsequent preference for that odor. In choice tests following the treatment period, female infants displayed preferential orientation to the exposure odor. Males, in contrast, displayed no evidence of preference for the exposure odor; rather, they demonstrated a right turning bias regardless of odor location. These data suggest that familiarization with an odor shortly after birth is sufficient for female infants to develop preferential responsiveness to that odor.     

Are women invisible as leaders?

This study shows that women are unlikely to be seen as leaders. Subjects (n=448) rated each member of a five-person group (shown in a photograph) on leadership attributes and also chose one of the five as “contributing most to the group.” Eight different stimulus slides were used. In two slides the “head-of-the-table” cue to group leadership was pitted against sex-role stereotypes. A man seated at the head of the table in a mixed-sex group was clearly seen as leader of his group, but a woman occupying the same position was ignored. The head-of-the-table cue identified women as leaders only in all-female stimulus groups. The data were consistent with the hypotheses that sex stereotypes still control social judgments, and that discrimination operates nonconsciously and in spite of good intentions.     

Instrumental escape behavior with extended training

Four groups of nine Ss were run in a straight alley shock situation for 240 trials, 30 per day. Ss received either 180- or 300-V shock and interval intervals (ITI) of 30 or 120 sec. On Day 1 of training, the 300-V groups first started faster than the 180-V groups, but then showed considerable adaptation, resulting in approximately equal performance at the end of Day 1. Over all 8 days, the 180-V group started significantly faster than the 300-V group when a 30-sec ITI was used, but the converse when a 120-sec ITI was used. Over all 8 days, the 300-V groups continued to increase in performance, while the 180-V groups showed a decline after Day 4.
