Resolving conflicting views: Gaze and arrow cues do not trigger rapid reflexive shifts of attention

It has become widely accepted that the direction of another individual's eye gaze induces rapid, automatic, attentional orienting, due to it being such a vital cue as to where in our environment we should attend. This automatic orienting has also been associated with the directional-arrow cues used in studies of spatial attention. Here, we present evidence that the response-time cueing effects reported for spatially nonpredictive gaze and arrow cues are not the result of rapid, automatic shifts of attention. For both cue types, response-time effects were observed only for long-duration cue and target stimuli that overlapped temporally, were largest when the cues were presented simultaneously with the response-relevant target, and were driven by a slowing of responses for invalidly cued targets rather than speeding for validly cued ones. These results argue against automatic attention-orienting accounts and support a novel spatial-incongruency explanation for a whole class of rapid behavioural cueing effects.     

Forgoing Debriefing in Deceptive Research: Is It Ever Ethical?

The use of deception in research is generally permitted so long as participants are debriefed at the conclusion of their participation. Several authoritative research ethics guidelines allow investigators to omit debriefing under certain circumstances, however. Here we examine various justifications for forgoing debriefing in deceptive research, including concerns about subject pool contamination, the risk that revealing the deception will be harmful or distressing to participants, and issues of practicability. We conclude that, contrary to current practice, omitting debriefing is ethically acceptable only when debriefing is impracticable, the deception is innocuous, and no reasonable person would object to involvement in the research.     

The Need for Power and Fear of Assertiveness in English-Speaking South African Female Graduates

The present study demonstrated that Winter's (1973) power arousal procedure and scoring system for the need for power, which were developed in the United States, are valid for English-speaking South African female graduates. Subjects in whom the need for power had been aroused by a prerecorded inspirational speech (n = 20) had significantly higher n Power scores than matched nonaroused subjects (n = 20), T ²(8, 31) = 56.17, p ≤ .01. Further, it was argued that the fear of assertiveness is a component of the need for power, and a scoring system for measuring this motive was suggested. Fear of assertiveness was shown to correlate significantly with various behavioral and dispositional measures of assertiveness, relating especially to a dependency pattern of behavior.     

Single-Letter Retrieval Cues for Anagram Solution

Anagram solution, as related to single-letter retrieval cues and first letter of the solution word (consonant or vowel), was examined. In Experiment 1, college-aged solvers were presented both types of 5-letter words and either the first letter of the solution word as a cue, or no cue. In Experiment 2, the effects of four types of retrieval cues (first, middle, or last letter or no cue) upon solving consonant-beginning words was examined. Finally, Experiment 3 examined the solution of both types of solution words as related to the preceding four types of retrieval cues. The results of all 3 experiments showed that a single letter can be an effective cue. For consonant-beginning words, the middle and last letters were as effective as the first letter. For vowel-beginning words, the first letter was more effective than either the middle or last letter. It was concluded that solvers select one letter of the anagram, typically a consonant, to serve as the first letter of the solution word, and then rearrange the remaining letters.     

African American Children's Ability to Identify Emotion in Facial Expressions and Tones of Voice of European Americans

This study examined whether African American children's ability to identify emotion in the facial expressions and tones of voice of European American stimuli was comparable to their European American peers and related to personality, social competence, and achievement. The Diagnostic Analysis of Nonverbal Accuracy (DANVA; Now-icki & Duke, 1994) was administered to 84 African American children. It was found that they performed less accurately on adult and child tones of voice and adult facial expressions. Further, girls' ability to read emotion in tones of voice was related to better social competence and achievement, whereas boys' ability to identify emotion in adult tones of voice was related to teacher-rated social competence. Results suggest that more research is needed with ethnic groups to clarify the impact of nonverbal processing skills on social and achievement outcomes.     

Relations between 18-month-olds’ gaze pattern and target action performance: A deferred imitation study with eye tracking

Deferred imitation studies are used to assess infants’ declarative memory performance. These studies have found that deferred imitation performance improves with age, which is usually attributed to advancing memory capabilities. Imitation studies, however, are also used to assess infants’ action understanding. In this second research program it has been observed that infants around the age of one year imitate selectively, i.e., they imitate certain kinds of target actions and omit others. In contrast to this, two-year-olds usually imitate the model's exact actions. 18-month-olds imitate more exactly than one-year-olds, but more selectively than two-year-olds, a fact which makes this age group especially interesting, since the processes underlying selective vs. exact imitation are largely debated. The question, for example, if selective attention to certain kinds of target actions accounts for preferential imitation of these actions in young infants is still open. Additionally, relations between memory capabilities and selective imitation processes, as well as their role in shaping 18-month-olds’ neither completely selective, nor completely exact imitation have not been thoroughly investigated yet. The present study, therefore, assessed 18-month-olds’ gaze toward two types of actions (functional vs. arbitrary target actions) and the model's face during target action demonstration, as well as infants’ deferred imitation performance. Although infants’ fixation times to functional target actions were not longer than to arbitrary target actions, they imitated the functional target actions more frequently than the arbitrary ones. This suggests that selective imitation does not rely on selective gaze toward functional target actions during the demonstration phase. In addition, a post hoc analysis of interindividual differences suggested that infants’ attention to the model's social-communicative cues might play an important role in exact imitation, meaning the imitation of both functional and arbitrary target actions.     

Effects of Deception on Children's Understanding of Second‐order False Belief

This research examined two questions: effects of deception on children's understanding of second‐order false belief, and possible effects of number of siblings on second‐order performance. Kindergarten children responded to 3 second‐order problems that varied in the presence and the nature of deception. Performance was better on the problems with deception, but significantly so only when the target for the belief attribution produced the deception. This finding helps to clarify differences between the two main paradigms for assessing second‐order false belief. There was no relation between number of siblings and performance.

Deception,Catholicism, and Hope: Understanding Problems in the Communication of Unfavorable Prognoses in Traditionally-Catholic Countries

The doctor's use of deception in appropriate circumstances has commonly been considered a necessity of the medical art. Resistance to full and frank communication is typical of many traditionally Catholic countries, and particularly of Italy, a western country where Catholicism remains particularly influential. The Catholic teaching on truth and lies, and the problem of telling the truth to a severely ill patient is discussed. It is suggested that the contemporary Catholic model of gradually telling a terminal patient the truth, which looks reasonable and feasible in theory, is rarely followed in practice, as in the majority of cases the truth is not told tout court. Problems stem from the way in which medicine is currently practiced in Italy; from the synergism between Catholicism and the medical tradition's grounded paternalism; and from the ambiguity of the term ‘hope’. Catholic ethics in fact recommends that the truth must be told without destroying hope, but the Catholic meaning of ‘hope’ is very different from its meaning in current language.     

Lying to Insurance Companies: The Desire to Deceive among Physicians and the Public

This study examines the public's and physicians' willingness to support deception of insurance companies in order to obtain necessary healthcare services and how this support varies based on perceptions of physicians' time pressures. Based on surveys of 700 prospective jurors and 1617 physicians, the public was more than twice as likely as physicians to sanction deception (26% versus 11%) and half as likely to believe that physicians have adequate time to appeal coverage decisions (22% versus 59%). The odds of public support for deception compared to that of physicians rose from 2.48 to 4.64 after controlling for differences in time perception. These findings highlight the ethical challenge facing physicians and patients in balancing patient advocacy with honesty in the setting of limited societal resources.
