On the heritability of inspection time and its covariance with IQ: a twin study

Using the classical twin design, this study investigates the influence of genetic factors on the large phenotypic variance in inspection time (IT), and whether the well established IT–IQ association can be explained by a common genetic factor. Three hundred ninety pairs of twins (184 monozygotic, MZ; 206 dizygotic, DZ) with a mean age of 16 years participated, and 49 pairs returned approximately 3 months later for retesting. As in many IT studies, the pi figure stimulus was used and IT was estimated from the cumulative normal ogive. IT ranged from 39.4 to 774.1 ms (159±110.1 ms) with faster ITs (by an average of 26.9 ms) found in the retest session from which a reliability of .69 was estimated. Full-scale IQ (FIQ) was assessed by the Multidimensional Aptitude Battery (MAB) and ranged from 79 to 145 (111±13). The phenotypic association between IT and FIQ was confirmed (−.35) and bivariate results showed that a common genetic factor accounted for 36% of the variance in IT and 32% of the variance in FIQ. The maximum likelihood estimate of the genetic correlation was −.63. When performance and verbal IQ (PIQ & VIQ) were analysed with IT, a stronger phenotypic and genetic relationship was found between PIQ and IT than with VIQ. A large part of the IT variance (64%) was accounted for by a unique environmental factor. Further genetic factors were needed to explain the remaining variance in IQ with a small component of unique environmental variance present. The separability of a shared genetic factor influencing IT and IQ from the total genetic variance in IQ suggests that IT affects a specific subcomponent of intelligence rather than a generalised efficiency.     

Pregnancy in the workplace: Does pregnancy affect performance appraisal ratings?

Archival data were collected to examine bias effects in performance evaluation related to employee pregnancy. Prior survey research has suggested that many supervisors and co-workers hold negative views of pregnant employees. Performance appraisal ratings were collected before, during, and after pregnancy for employees taking maternity leave over a four year time frame. In addition, data was also collected from randomly selected control subjects, which were matched on job title and observation period. Contrary to expectations, performance appraisal ratings were found to increase during pregnancy when compared to before ratings and control group ratings. Potential explanations as well as suggestions for further research are discussed.

支持死后医疗数据捐赠：呼吁对个人健康数据的伦理利用

死后医疗数据捐赠对于科学研究的意义重大。但目前不存在有针对性的准则用于指导捐赠过程。如果死后医疗数据的使用缺乏监管可能会引发多种风险,一是给他人利益造成损害;二是造成数据的不规范使用。因此,应当类比现有捐献制度,允许并鼓励捐献死后医疗数据用于科学研究,并起草专门的捐赠准则。该准则的制定应当建立在遵循五大基本原则的前提下,主张以自愿参与的方式使用个人医疗数据,反对未经书面同意将数据用于以病例档案为基础的医学研究。

     

Source monitoring in Alzheimer's Disease

Source monitoring is the process of making judgments about the origin of memories. There are three categories of source monitoring: reality monitoring (discrimination between self- versus other-generated sources), external monitoring (discrimination between several external sources), and internal monitoring (discrimination between two types of self-generated sources). We investigated whether Alzheimer's Disease (AD) patients, when compared with young and older adults, are impaired at the same level on the three source monitoring categories. We designed three tasks, one for each source monitoring category. In the first task, aimed at reality monitoring, participants had to remember whether objects were previously placed in a bag by themselves or by the experimenter. In the second task, assessing external monitoring, participants had to remember whether the experimenter had previously placed objects in the bag with a black or white gloved hand. In the third task, measuring internal monitoring, participants had to remember whether they had previously placed or imagined themselves placing objects in the bag. Participants showed worse performances in the external and internal monitoring tasks, when compared with reality monitoring. The external monitoring deficit was even more pronounced in AD patients. Regression analyses showed that variation in the external monitoring performances was reliably predicted by inhibition. Our results emphasize the role of inhibitory processes in AD patients' source monitoring decline. The close relation between source and inhibitory decline in AD is interpreted in terms of a common neural base for both concepts.     

Children's interpretive understanding,moral judgments,and emotion attributions: Relations to social behaviour

The study investigated interpretive understanding, moral judgments, and emotion attributions in relation to social behaviour in a sample of 59 5‐year‐old, 123 7‐year‐old, and 130 9‐year‐old children. Interpretive understanding was assessed by two tasks measuring children's understanding of ambiguous situations. Moral judgments and emotion attributions were measured using two moral rule transgressions. Social behaviour was assessed using teachers' ratings of aggressive and prosocial behaviour. Aggressive behaviour was positively related to interpretive understanding and negatively related to moral reasoning. Prosocial behaviour was positively associated with attribution of fear. Moral judgments and emotion attributions were related, depending on age. Interpretive understanding was unrelated to moral judgments and emotion attributions. The findings are discussed in regard to the role of interpretive understanding and moral and affective knowledge in understanding children's social behaviour.     

Alexithymia in Young people’s academic career: The mediating role of anxiety and resilience

Alexithymia prevents people from understanding and adopting verbal language to describe and regulate one’s emotions. Recent studies have found that alexithymia symptoms also impact on young people’s academic achievement. Nevertheless, it is worth investigating risk and protective roles played by students’ academic anxiety and resilience, respectively. The authors expected that students’ anxiety and resilience mediated the effect of alexithymia symptoms on students’ academic burnout and performance. A sample of 257 university students answered self-report questionnaires about alexithymia, academic anxiety and resilience, and academic burnout and performance. Mediation analyses were performed by the structural equation model. Anxiety acted as a mediator between alexithymia and academic burnout and performance. Furthermore, resilience mediated the effect of alexithymia on burnout, but not on academic performance. The study provides support for preventing alexithymia consequences on young people’s academic career by reducing their anxiety and promoting academic resilience. Implications of intervention programs were discussed.     

The involuntary nature of music-evoked autobiographical memories in Alzheimer's disease

The main objective of this paper was to examine the involuntary nature of music-evoked autobiographical memories. For this purpose, young adults, older adults, and patients with a clinical diagnosis of probable Alzheimer's disease (AD) were asked to remember autobiographical events in two conditions: after being exposed to their own chosen music, and in silence. Compared to memories evoked in silence, memories evoked in the "Music" condition were found to be more specific, accompanied by more emotional content and impact on mood, and retrieved faster. In addition, these memories engaged less executive processes. Thus, with all these characteristics and the fact that they are activated by a perceptual cue (i.e., music), music-evoked autobiographic memories have all the features to be considered as involuntary memories. Our paper reveals several characteristics of music-evoked autobiographical memories in AD patients and offers a theoretical background for this phenomenon.     

What is A Philosophical Question?

There are many ways of understanding the nature of philosophical questions. One may consider their morphology, semantics, relevance, or scope. This article introduces a different approach, based on the kind of informational resources required to answer them. The result is a definition of philosophical questions as questions whose answers are in principle open to informed, rational, and honest disagreement, ultimate but not absolute, closed under further questioning, possibly constrained by empirical and logico‐mathematical resources, but requiring noetic resources to be answered. The article concludes with a discussion of some of the consequences of this definition for a conception of philosophy as the study (or “science”) of open questions, which uses conceptual design to analyse and answer them.
