Out of mind,out of sight? Investigating abnormal face scanning in autism spectrum disorder using gaze‐contingent paradigm

Diminished social motivation is hypothesized to explain abnormal face scanning pattern in individuals with autism spectrum disorder (ASD), especially reduced eye‐looking time in ASDs than typically developing (TD) people. Here, we tested an alternative explanation that children with ASD may use a compensatory strategy to avoid direct eye contact by processing the eyes through peripheral vision. We compared the face scanning patterns of children with and without ASD in two conditions: in the clear condition, the face was completely visible; in the blur condition, by using the gaze‐contingent paradigm, the whole face was blurred except for a small region being fixated at, thus children could not rely on the peripheral information to process the eyes. We found that children with ASD fixated less on the eyes than TD children in both conditions. Temporal‐course analyses further revealed the possible motivation‐based guidance of attention to process the eyes in the TD group but not in the ASD group. Additionally, we found that children with ASD scanned faces more randomly and less strategically than TD children. These results have ruled out the alternative hypothesis that the abnormal face scanning pattern in ASDs was due to their compensatory strategy to process eyes through peripheral vision, furthering our understanding of the mechanisms underlying their abnormal face scanning.     

变革型领导与交易型领导的权变分析

变革型领导与交易型领导是当前领导研究的热点。一般认为,变革型领导是比交易型领导更为有效的领导方式。然而从权变的观点出发,变革型领导与交易型领导的有效性还要受到情境因素、被领导者因素的影响。该文分析了替代领导、领导与下属的关系以及组织文化对变革型领导和交易型领导与领导效能关系的调节作用,并讨论了今后的领导行为研究中应该注意的问题。     

THE EXISTENCE OF GOD AND THE CREATION OF THE UNIVERSE

Abstract. Kant argues that any argument for a transcendent God presupposes the logically flawed ontological argument. The teleological argument cannot satisfy the demands of reason for a complete explanation of the meaning and purpose of our universe without support from the cosmological argument. I avoid the assumption of a perfect being, and hence the ontological argument, in my version of the cosmological argument. The necessary being can be identified with the creator of the universe by adding analogical mental relations. The creation of the universe is then shown to reflect modern scientific cosmology as well as stories and metaphors in the Eastern and Western religious traditions and to resolve the problem of evil.

Primes, contingent attention, and training: effects on a child's motor behavior

The use of primes, contingent attention, and training sessions to assess a child's engagement and skill in six large motor activities was examined using a combination reversal and multiple-baseline design. Assessment was based on four levels: proximity to equipment, touching equipment, unskilled participation, and skilled participation. Before training, priming (suggestion to the child) was more effective than contingent attention for increasing the subject's engagement (but not skill) in five activities and for increasing skilled participation in one activity. Training of four activities in the natural environment effectively increased the subject's skill level in five activities. Thus, training appeared to generalize to one of these five activities in this setting and also to skillfully executed stair climbing in an adjoining setting. After training, primes and contingent attention were sufficient to maintain both the subject's skill level and engagement in all activities. Postchecks in the same setting the following semester with different teachers revealed only slight increases in participation, as compared to previous baselines, but all participation was at the skilled level. Social interaction, which was not experimentally manipulated, did not systematically vary in relation to changes in experimental conditions.     

Contingent approaches to making likelihood judgments about polychotomous cases: the influence of task factors

Two experiments tested the influence of three task factors on respondents' tendency to use normative, heuristic, and random approaches to making likelihood judgments about polychotomous cases (i.e., cases in which there is more than one alternative to a focal hypothesis). Participants estimated their likelihood of winning hypothetical raffles in which they and other players held various numbers of tickets. Responding on non‐numeric scales (vs. numeric ones) and responding under time pressure (vs. self‐paced) increased participants' use of a comparison‐heuristic approach, resulting in non‐normative judgment patterns. A manipulation of evidence representation (whether ticket quantities were represented by numbers or more graphically by bars) did not have reliably detectable effects on processing approaches to likelihood judgment. The authors discuss the implications of these findings for the further development of likelihood judgment theories, and they discuss parallels between contingent processing in choice and contingent processing in likelihood judgment.

A contingent perspective on the advantages of stores' strategic philanthropy for influencing consumer behaviour

The importance and implications of organisational‐level charitable giving, or strategic philanthropy, are often overlooked in international consumer literature. Drawing on the utilitarian human capital perspective from economics, the social norm theory from sociology, motivation theory from psychology and the strategy–environment coalignment paradigm in organisational science, this research develops a contingent framework for strategic philanthropy. The empirical results indicate that if drug stores put more emphasis on strategic philanthropy as perceived by customers in the community, customers will have stronger social ties with the store and be more loyal to the store. In addition, it was found that the impact of strategic philanthropy on patronage loyalty is moderated by customer characteristics (gender and ethnicity) and context factors (service quality and cause severity).

Repeated post- or presession cocaine administration: roles of dose and fixed-ratio schedule

Effects of repeated administration of cocaine to animals behaving under operant contingencies have depended on when the drug is given. Moderate doses given presession have generally led to a decrease in the drug's effect, an outcome usually referred to as tolerance. When these same doses have been given after sessions, the usual result has been no change or an increase in the drug's effects, with the latter usually referred to as sensitization. In the present study, repeated postsession administration of a relatively small dose of cocaine (3.0 or 5.6 mg/kg) to pigeons responding under a multiple fixed-ratio 5, fixed-ratio 100 schedule of food presentation generally resulted in tolerance to the rate-decreasing effects of the drug. When the same dose was given before sessions, little additional tolerance was observed, although some subjects showed further tolerance in the small-ratio component. A regimen of repeated postsession injection of larger (10.0-23.0 mg/kg) doses suppressed key pecking during the session; responding resumed following discontinuation of postsession administrations. Effects of postsession administration of cocaine, therefore, depended on the dose, with smaller doses leading to tolerance and larger ones to suppression of behavior during the session. Effects of postsession drug administration of either small or large doses were not related to whether effects of postsession drug were experienced mainly in the operant test chamber or in the pigeon's home cage. The results with large postsession doses are compatible with a view that the drug acted as a Pavlovian unconditional stimulus, with the session-related stimuli acting as a long-duration Pavlovian conditional stimulus. Tolerance following postsession administration of the smaller doses challenges the view that it depended on experiencing the drug's effects while the arranged reinforcement contingencies were in effect.     

Quel engagement organisationnel pour les salariés précaires ? Les leçons d’une étude empirique auprès de travailleurs intérimaires

The aim of this article is to focus on contingent workers’ organizational commitment. A review of literature on contingent workers’ attitudes leads to think that this type of work arrangement is associated with a high level of job insecurity, which is not favourable to organizational commitment. However, empirical studies present very contrasting results. This absence of consensus leads us to propose a research model, which puts the emphasis on the way the temporary workers interpret their job arrangement. The model was tested on 208 temporary help service workers. The results highlight the mediating role of perceived job insecurity on organizational commitment, as well as importance of perceived organizational support (POS).
