Socioeconomic status and hippocampal volume in children and young adults

An individual's socioeconomic status (SES) is often viewed as a proxy for a host of environmental influences. SES disparities have been linked to variance in brain structures particularly the hippocampus, a neural substrate of learning and memory. However, it is unclear whether the association between SES and hippocampal volume is similar in children and adults. We investigated the relationship between hippocampal volume and SES in a group of children (n = 31, age 8–12 years) and a group of young adults (n = 32, age 18–25 years). SES was assessed with four indicators that loaded on a single factor, therefore a composite SES scores was used in the main analyses. Hippocampal volume was measured using manual demarcation on high resolution structural images. SES was associated with hippocampal volume in the children, but not in adults, suggesting that in childhood, but not adulthood, SES‐related environmental factors influence hippocampal volume. In addition, hippocampal volume, but not SES, was associated with scores on a memory task, suggesting that net effects of postnatal environmental factors, captured by SES, are more distal determinants of memory performance than hippocampal volume. Longitudinal investigation of the association between SES, hippocampal volume and cognitive functioning may further our understanding of the putative neural mechanisms underlying SES‐related environmental effects on cognitive development.     

Suggestion reduces the stroop effect

We examined the effects of suggestion on Stroop interference in highly suggestible individuals. Participants completed the Stroop task with and without a suggestion to perceive Stroop words as meaningless symbols. Half the participants were given this suggestion in hypnosis, and half were given the suggestion without the induction of hypnosis. Suggestion produced a significant reduction in Stroop inhibition, accounting for about 45% of the variance in Stroop responding, regardless of whether hypnosis had been induced. These findings indicate that suggestion can at least partially overcome the automaticity associated with the Stroop effect.     

Nondirectiveness and Its Lay Interpretations: The Effect of Counseling Style, Ethnicity and Culture on Attitudes Towards Genetic Counseling Among Jewish and Bedouin Respondents in Israel

To evaluate the effects of ethnicity, culture, and counseling style on the interpretation of nondirectiveness in genetic counseling, a questionnaire containing premarital and prenatal case vignettes in two versions (pessimistic/optimistic) was administered to 281 Jewish and 133 Bedouin respondents. The first study population was comprised of Jewish students enrolled in a university and a community college in the Negev (southern part of Israel). The second study population was comprised of Muslim-Bedouin college students from the same area. The majority of Jewish respondents interpreted the nondirective message as intended by counselors, while the majority of Bedouin respondents did not. Counseling style was found to have a statistically significant effect on the interpretation of the general role of counseling. Gender and susceptibility were not found to have a significant effect on interpretation. Group differences are analyzed through a cultural lens in which different interpretive norms can generate expectations for either nondirectiveness or directiveness.     

The neural reality of syntactic transformations: evidence from functional magnetic resonance imaging

The functional anatomy of syntactic transformations, a major computational operation invoked in sentence processing, was identified through a functional magnetic resonance imaging investigation. A grammaticality judgment task was used, presented through a novel hidden-blocks design. Subjects listened to transformational and nontransformational sentences in which a host of other complexity generators (number of words, prepositions, embeddings, etc.) were kept constant. A series of analyses revealed that the neural processing of transformations is localizable, evoking a highly lateralized and localized activation in the left inferior frontal gyrus (Broca's region) and bilateral activation in the posterior superior temporal sulcus. The pattern of activation associated with transformational analysis was distinct from the one observed in neighboring regions, and anatomically separable from the effects of verb complexity, which yielded significant activation in the left posterior superior temporal sulcus. Taken together with neuropsychological evidence, these results uncover the neural reality of syntactic transformations.     

The Applicability of the Door-in-the Face Technique when Established Behavioral Customs Exist

The applicability of the door-in-the-face technique was tested in a monetary donation context where established behavioral standards exist, and where the target person has standards by which to judge the legitimacy of the solicitor's demand. Based on the proposition that exaggerated initial requests might discredit the solicitor and thereby halt the give-and-take process, it was expected that (a) with legitimate initial requests, the probability of compliance with a request would be greater when preceded by a larger request than if presented alone; and that (b) with illegitimate initial requests, the probability of compliance with a second request would be smaller when preceded by a larger request than if presented alone. On the national collection day for the Association for the Rehabilitation of the Mentally Handicapped, 400 subjects were asked to contribute IL 10, 15, or 20. In the experimental groups, these amounts were preceded with requests for larger sums which were judged previously by a pretest to be considered legitimate or illegitimate. In the control groups, subjects were asked to contribute the same amounts, but no larger amounts were first requested. The replicability of the door-in-the-face technique has been proven with requests for which established customs exist. However, the technique was only effective with legitimate initial requests. With initial requests that were previously judged as unreasonable, the technique had a "boomerang effect" and suppressed compliance.     

Akiva Yosef Schlesinger—a forerunner of Zionism or a forerunner of ultra-orthodoxy

Rabbi Akiva Yosef Schlesinger (Pressburg 1838—Jerusalem 1922) is considered by some scholars to be a forerunner of ultra-Orthodoxy, but by others as a forerunner of Zionism. This article unravels this enigmatic personality, demonstrating that he was indeed a forerunner of ultra-Orthodoxy who was motivated by a complete rejection of modernity and promoted religious positions that were more radical than those of the Hatam Sofer. Those who associate Schlesinger with Zionism are misled by the fact that he encountered fierce opposition from his Hungarian colleagues and from the “Yishuv hayashan” in Jerusalem, advocated the use of the Hebrew language and promoted a “settlement” programme in Palestine. The article suggests that Schlesinger's programme was in reality designed to create a sacred utopian society, and was motivated by his desire to isolate the traditional Jewish community from modernity, rather than by a nationalist ideology. Furthermore, the opposition of the Jerusalem rabbis to Schlesinger's ideas was based largely on his unusual religious positions and his suggestion that the youth should be engaged in work. In analysing Schlesinger's legacy, the article also clarifies the distinctions between ultra-Orthodoxy and Zionism, as well as some common elements that they share.
