Latent timing in human conditioned avoidance

Four experiments explored signal timing in human conditioned avoidance. Participants received discrimination training with different duration signals that announced the outcome (S+) or not (S-). Temporal discrimination and superposition of performance to S+ signals of different length (3, 6, or 9 s) was found both in within-subjects (Experiment 1a) and between-subjects (Experiment 1b) designs. S- signals also produced a temporal discrimination and superposition effect during a single test trial conducted after the meaning of the signals was reversed through instructions. Experiments 2a and 2b replicated these results in a situation in which (a) the durations of the S+ and S- signals were different (4.5 or 9 s) to prevent any temporal generalization between them (Experiment 2a), and (b) only S- signals were presented during training, precluding developing of inhibition to S- (Experiment 2b). These results show that participants time both S+ and S- signals in human conditioned avoidance, and they further suggest that the timing of a cue is independent of reinforcement.     

Criteria, indicators and standards of accreditation of tenured University professors in Spain

The purpose of the work is to establish the criteria, indicators and standards of accreditation of the tenured university professors according to the opinion of Associate Professors and Professors. It is a cross-sectional study of the populations by means of surveys with probabilistic samples. The sample consisted of 1,294 university professors of whom 72% were Associate Professors and 28% Professors. The sample was selected by proportional cluster random sampling (the Full Professors' types and the fields of knowledge). A survey was used to establish criteria, indicators, and standards for each type of professor. The results show different standards according to the criteria in different fields of knowledge. Qualitative differences (according to the criteria) and quantitative differences (according to the standards) to accredit Associate Professors and Professors were found.     

Masculinity and femininity scales: current state of the art

A theoretical and empirical review of masculinity and femininity scales was carried out after 30 years of their existence. Hypotheses to be tested were: (a) muldimensionality versus bidimensionality; (b) inadequate percentage of variance accounted for (less than 50%); (c) inconsistency between factor structure and the dualistic model. 618, 200 and 287 students took part in each of the three studies that were carried out. Factorial analyses (PAF) were performed. Results support multidimensionality, unsatisfactory percentage of variance accounted for, and lack of congruence between obtained factors and the dualistic model. All these data were analysed within the context of the twofold sex and gender reality model.     

Language is not neutral. Commentary about APA style

Some basic characteristics, not always explicit, of the editorial style proposed by the American Psychological Association (APA), and from the objections posed by some authors who maintain critical positions towards the use of this style, are reviewed, starting with the work of Madigan, Johnson, and Linton (1995) and the subsequent controversy. Starting with this review, problems related to underlying assumptions of the style, with ethical aspects of research, and with the epistemological positions defended by the different traditions of research are discussed. In the conclusions, a simpler differentiation between the scientific-technical and communicative-practical systems of enquiry is proposed, and an explicit commitment, in the text of the report, to the ethical responsibilities derived from the authorship and the development of the research.     

Neuropsychological profile of multiple sclerosis

Multiple Sclerosis (MS) is the most common non-traumatic neurological disorder among young and middle-aged people. The aim of the present study was to examine the cognitive functioning of a group of MS patients. A sample of 80 participants diagnosed with MS and 40 controls received a comprehensive neuropsychological battery. Participants with MS scored lower than controls on all of the neuropsychological tests and significantly lower (p < .05) on 84% (16/19) of them. The global neuropsychological profile of the MS group included deficits in executive function, speed of information processing, memory, visuo-spatial abilities and attention. Cognitive deficits are one of the main symptoms of MS. Recognition of these deficits is relevant both to the diagnosis and rehabilitation of this disorder.     

The manifestation of attentional capture: facilitation or IOR depending on task demands

Orienting attention exogenously to a location can have two different consequences on processing subsequent stimuli appearing at that location: positive (facilitation) at short intervals and negative (inhibition of return) at long ones. In the present experiments, we manipulated the frequency of targets and responses associated with them. Results showed that, even at long SOAs, where IOR is usually observed, facilitation was observed for infrequent targets at the same time that IOR was measured for frequent targets. These results are difficult to explain on the basis of either task set modulation of attentional capture or task set modulation of subsequent orienting processes. In contrast, we offer an explanation by which the different cuing effects can be considered as different manifestations of attentional capture on target processing, depending on the task set.     

大学生网络捐助的影响因素:求助者特征的视角

以往关于捐助的心理学研究主要聚焦于现实环境中的捐助行为,以及捐助者自身特点对捐助的影响,网络环境、求助者特征对捐助影响的研究较少。本研究以大学生为被试,比较不同信息发布者情境中,网络与现实中捐助的意愿,并确定求助者的身份特征和求助信息特征对网络捐助的影响。结果发现,在捐助意愿和捐助金额方面,网络渠道高于现实渠道、熟人发布高于陌生人发布;当求助者与捐助者同为大学生时,捐助者对求助者的理性求助信息比情绪性求助信息有更强的捐助意愿和更多捐助金额。以上结果与大学生网络社会支持水平较高、处理网络信息能力较强有关。     

运动习惯与社区老年人认知功能的关系

为评估社区老年人运动习惯与认知功能的关系,在北京市通过分层、方便取样的方法选取60岁以上的老年人732名,采用自编调查表收集一般人口学资料及运动习惯情况（包括有无运动习惯,运动频率,运动持续时间）,使用简明精神状态评估量表（MMSE）和北京版蒙特利尔认知评估量表（MoCA-BJ）评估认知功能。结果发现：（1）运动组整体认知功能及视空间定向能力得分均高于无运动组;（2）有无运动习惯可正向预测整体认知功能及视空间定向能力得分;（3）运动持续10年及以上组整体认知功能得分高于运动持续10年以下组。结果表明：相对于无运动习惯的社区老年人,有运动习惯的社区老年人的整体认知功能及视空间定向能力更好;运动持续年数较长,对社区老年人的认知功能起到促进作用。     

Individual differences in anger and displaced aggression: The role of metacognitive beliefs and anger rumination

Metacognitive model is a theoretical approach aimed to explain emotion dysregulation and others emotion-related issues, such anger, and aggressive behavior. From this model, people having higher maladaptive metacognitive beliefs (e.g., “I can't control my thoughts”) are more likely to activate and maintain anger rumination and, in turn, to experience higher levels of anger and to act aggressively. Preliminary evidence shows the role of metacognitive beliefs on anger rumination and anger levels, whereas no studies have examined its association with aggressive behavior. This study first examined the associations between metacognitive beliefs, anger rumination, anger levels, and the propensity to engage in displaced aggression, and second, the mediation role of anger rumination in the relations among metacognitive beliefs and anger and displaced aggression. Participants were 947 students and non-students from general population recruited in two different countries (Australia and Spain). Correlational analyses revealed a similar pattern of results in the Australian and Spanish sample, with participants having dysfunctional metacognitive beliefs also showing higher anger rumination, higher levels of anger and a higher tendency to act aggressively. Structural equation analyses revealed the associations of metacognitive beliefs with anger levels and displaced aggression was fully mediated by anger rumination in both samples. These results suggest that metacognitive beliefs should be considered in comprehensive models and in the therapy of anger problems and aggression.     

Aggressive behavior of pigeons: Suppression by archistriatal lesions

The agonistic responses of pigeons to the introduction of a stick and the experimenter's hand into their home cages is described. The effects of lesions of the archistriatum, a presumed homologue of the mammalian amygdala, of lesions of the overlying neostriatum and of control sham operations on this behavior in selected aggressive pigeons are reported. Only archistriatal lesions lead to a persistent depression of the aggressive and a converse increment of the avoidance components of the pigeon's response to both test stimuli. The results are discussed in relation to other evidence on the role of the avian archistriatum and this structure's correspondence with the amygdala.
