Revisiting the definition of homo sapiens

Research in genomics, human cloning, and transgenic technology has challenged bioethicists and scientists to rethink the definition of human beings as a species. For example, should the definition incorporate a genetic criterion and how does the capacity to genetically engineer human beings affect the definition of our species? In considering these contemporary bioethical dilemmas, we revisit an ancient source, the Talmud, and highlight how it provides specific biological, cultural, and genetic criteria to define the human species.     

Topological duality for distributive Ockham algebras

In this note, we give a representation of distributive Ockham algebras via natural hom-functors. In order to do this, we describe two different structures (one algebraic, and the other order-topological) on the set of subsets of the natural numbers. The topological duality previously obtained by A. Urquhart is used throughout.     

Emotional intelligence (EI), conflict resolution patterns,and relationship satisfaction: Actor and partner effects revisited

This study tested for actor and partner effects in the relationship between ability-based EI and adaptive marital relationships and satisfaction employing a standard dyadic design involving 100 young heterosexual couples. Participants were assessed on the MSCEIT along with measures of conflict resolution patterns and perceived marital satisfaction. A series of path analyses provided support for actor effects—but not partner effects—in the association of EI, assessed as ability, and marital variables. Overall, the data provide only partial support for the common claim and some prior research suggesting that EI plays a pivotal role in marital relationships.     

Familiarity and personal experience as mediators of recall when planning for future contingencies

In this article, we demonstrate that planning tasks enhance recall when the context of planning (a) is self-referential and (b) draws on familiar scenarios represented in episodic memory. Specifically, we show that when planning tasks are sorted according to the degree to which they evoke memories of personally familiar scenarios (e.g., planning a picnic), recall is reliably superior to tasks that fail to do so (e.g., planning an Arctic trek). We discuss the implications of these findings for planning tasks and their relation to episodic memory.     

Is the emotional Stroop task a special case of mood induction? Evidence from sustained effects of attention under emotion

Sustained effects of emotion are well known in everyday experience. Surprisingly, such effects are seldom recorded in laboratory studies of the emotional Stroop task, in which participants name the color of emotion and neutral words. Color performance is more sluggish with emotion words than with neutral words, the emotional Stroop effect (ESE). The ESE is not sensitive to the order in which the two groups of words are presented, so the effect of exposure to emotion words does not extend to disrupting performance in a subsequent block with neutral words. We attribute this absence of a sustained effect to habituation engendered by excessive repetition of the experimental stimuli. In a series of four experiments, we showed that sustained effects do occur when habituation is removed, and we also showed that the massive exposure to negative stimuli within the ESE paradigm induces a commensurately negative mood. A novel perspective is offered, in which the ESE is considered a special case of mood induction.     

Anxiety and bodily symptoms under the threat of missile attacks: The israeli scene

Abstract

The present research, conducted in Israel during the recent “Desert Storm” operation in the Gulf, sets out to assess the degree of anxiety and bodily symptoms of Israeli citizens, threatened by Scud missile attacks and undergoing a period of acute stress. Data were gathered via questionnaires distributed during the crisis period to over 500 respondents, most of them residing in Haifa, one of the high-risk areas for the missile attacks at the time. State anxiety was reported to be highly elevated during the crisis period, in comparison with norm group data collected during normal times. The most frequently reported bodily symptoms were changes in eating habits (loss of appetite or overeating), fatigue, and insomnia. Women reported more anxiety and bodily symptoms, on average, than men, as well as higher tension, fear and depression. The younger adults in the sample reported more anxiety and bodily symptoms, as well as tension, fear and depression, than their older counterparts. Lower levels of fear and depression were reported at the later stages of the crisis than at the earlier ones; most stress indicators evidenced lower levels with the passage of time. Finally, a strong positive relationship between anxiety and bodily symptoms was found, over and above the contribution of background variables and response tendencies. The possible explanations for the effects of background variables, as well as the strong relationship between anxiety and symptoms reported, are discussed.     

Knowledge and Action,Reason and Habit,in Jewish and Muslim Philosophies of Education

Jewish and Muslim philosophers, alike, regarded the formation of proper habits to be the key to effective education. They also considered rational acceptance of religious obligation to be mandatory for successful observance. This essay examines the relationship between these two dimensions of religious education: knowledge and reason on the one hand, and habit and action on the other hand, in the philosophical and pedagogical works of Abu Hāmid al-Ghazāli (1058–1111,) Moses Maimonides (1135–1204), and the anonymous Sefer Ha-Hinnukh (13th century).     

Does Test Anxiety Bias Scholastic Aptitude Test Performance by Gender and Sociocultural Group?

This study examines the commonly held contention that test anxiety may serve as a source of bias in the scholastic aptitude test performance of gender and ethnic minority groups. In addition, this study examines sex and sociocultural group differences in the level and pattern of test anxiety among Israeli college students. The sample was composed of 163 male and 198 female students sitting for scholastic aptitude tests routinely administered to all student applicants as part of their college admissions procedures. About 67% were of Western cultural extraction whereas the remainder were of Eastern extraction. Significant differences in text anxiety scores for males and females were observed, with greater sex group differentiation on the Emotionality than on the Worry scale. Test anxiety scores were not discernible by ethnicity or social class. Furthermore, test anxiety was not differentially related to aptitude test scores by sex or sociocultural group membership. Thus, this study lends little evidence to the common contention that test anxiety differentially debilitates the aptitude test scores of females and ethnic minority student candidates.     

Characterization of Memory Impairment Following Closed-Head Injury in Children Using the Rey Auditory Verbal Learning Test (AVLT)

Memory impairment following closed-head injury (CHI) in children is well documented. Characterization of the memory deficits of children with CHI could contribute to the prediction of academic performance and rehabilitation of these children. Twenty-five children who sustained closed-head injury and 25 matched controls were administered the Rey Auditory Verbal Learning Test (AVLT). The advantage of this memory test is that a number of memory components are measured simultaneously, thus enabling us to study the relations between different aspects of memory within the same patient sample. The findings indicate that the Rey AVLT is a good test for characterization of impaired verbal memory in children following CHI. Transformation of scores derived from the Rey AVLT to Z-scores enables us to determine the relative effect of CHI in children on different memory scores. Raw scores were more vulnerable than relational ones, derived as the difference between two raw scores (e.g., learning, Trial 5?1), to closed-head injury in children, and scores reflecting word span were the least vulnerable. The results are discussed in terms of the possible contribution of the frontal lobes, which are frequently affected in closed-head injuries, to memory performance.     

Age-Related Differences in Cued Recall: Effects of Support at Encoding and Retrieval

The literature is unclear about the relative contributions of environmental supporting conditions to younger and older adults’ episodic memory performance. The work reported addresses the conditions under which different support patterns are obtained. In three experiments, younger and older adults learned picture-word pairs and were then tested with a cued-recall task. Supportive conditions included semantic relations between the pair members (all experiments), and first-letter cues for the target words at retrieval (Experiments 2 and 3). Results of the three experiments indicated different patterns of support for younger and older adults, depending on the number and location of the supporting conditions used. These different patterns are in line with the suggestion that whereas younger adults benefit substantially from support at encoding only, older adults require support at both encoding and retrieval. Alternative accounts of the results are also discussed.
