Impaired pitch production and preserved rhythm production in a right brain-damaged patient with amusia

Pre- and postmorbid singing of a patient with amusia due to a right-hemispheric infarction was analyzed acoustically. This particular patient had a premorbid tape recording of her own singing without accompaniment. Appropriateness of pitch interval and rhythm was evaluated based on ratios of pitch and duration between neighboring notes. The results showed that melodic contours and rhythm were preserved but individual pitch intervals were conspicuously distorted. Our results support a hypothesis that pitch and rhythm are subserved by independent neural subsystems. We concluded that action-related acoustic information for controlling pitch intervals is stored in the right hemisphere.     

The Automatic Activation of Retributive Motive When Determining Punishment

This study sought to test the hypothesis that an individual’s retributive motive is activated automatically when he or she is presented with an opportunity to determine appropriate punishment. Fifty-one undergraduate students were subjected to one of two conditions: one in which an video clip of a brutal crime was presented (crime video condition) and another in which a sports documentary video clip was presented (sports video condition). Participants were asked to complete the Implicit Association Test before and after being presented with the video. It was predicted that the activation of retributive motive would strengthen the association with a balanced combination of these factors as compared to the association with an unbalanced combination of factors and increase the IAT effect accordingly. The IAT effect increased in the crime video condition but did not change in the sports video condition. This result supported the hypothesis, indicating that decision making regarding punishment is carried out automatically and outside of conscious awareness, as the IAT reflects automatic cognitive processes such as implicit attitudes.     

Selecting a Relevant Mental State in Young Children’s Persuasion

Previous studies have found that understanding another person’s mental states is a requirement for effective responding to that person. This study examined whether effective responding also requires selecting a relevant mental state of another person. Using a hypothetical persuasion paradigm, we investigated if late 4- and 5-year-olds (N = 120) could present information to counter a receiver’s opposition. For example, a boy is attempting to persuade his mother to let him have a bird. If the mother objects to her son having the bird because bird is noisy, then the boy should ask her to have a quiet bird. Presenting appropriate information (e.g., a quiet bird) was found to be more difficult when the person had plural beliefs (e.g., a bird would be clean and noisy) and children had to select the source of opposition (e.g., a bird would be noisy). This suggests that selecting an appropriate mental state of another person is necessary for effective responding. Contingency and developmental analyses revealed that children could present appropriate information only when they could select the source, indicating that the ability to select an appropriate mental state is a key factor in responding effectively to others.     

Sebastian Rodrigues in Shusaku Endo's Silence as a Theologian of the Cross1

In his book, On Being a Theologian of the Cross, Gerhard Forde asserts, “[T]he theology of the cross is an offensive theology. The offense consists in the fact that unlike other theologies it attacks what we usually consider the best in our religion.” If causing an offense against Christian theologians and the populace in general is considered a criterion for this theology, Shusaku Endo surely sets forth the theology of the cross in his novel, Silence. Although he would not identify his thesis by such a term, Endo presents the theology of the cross challenging the conventional understanding of the Christian faith. This short article explores Endo's book, Silence, examines how it demonstrates an articulation of the theology of the cross, and argues that Sebastian Rodrigues, the main character of the novel, is a theologian of the cross.     

Attacker's intent and awareness of outcome,impression management,and retaliation

Female Japanese students who were engaged in a calculation task were given electric shocks by a female opponent. The subjects were informed that the opponent had an intent to shock them either severely or mildly. In addition, the opponent's awareness of the outcome of attack was independently manipulated: (1) the subjects received shocks whose intensity corresponded to the opponent's intent, (2) the subjects received shocks whose intensity was inversely proportional to the intensity intended by the opponent and were informed that the opponent did not know about it, or (3) the subjects received reversed shocks as in condition (2), but were further informed that the opponent was well aware of it. An ANOVA of the measure of retaliation in terms of the intensity of shocks delivered to the opponent indicated that (1) the subjects showed more aggression of greater intensity against an opponent who apparently had an aggressive intent than the one who did not, regardless of the actual level of shock intensity; (2) when the severe attack failed, the subjects lowered aggression when the opponent was apparently aware of it as opposed to when she was not; and (3) when the subjects received severe shocks accidentally, they increased aggression when the opponent was apparently aware of it compared to when she was not. These results led us to interpret retaliation as being mediated both by the attribution of intent to the attacker and by self-presentation to the attacker and the experimenter.     

Ghrelin stimulates corticotropin-releasing factor and vasopressin gene expression in rat hypothalamic 4B cells

Corticotropin-releasing factor (CRF) and arginine vasopressin (AVP) play a central role in regulating the stress response. In response to stress, CRF and AVP neurons in the hypothalamic paraventricular nucleus secrete the peptides to stimulate the release of adrenocorticotropic hormone from the anterior pituitary. Ghrelin, an endogenous ligand of the growth hormone-releasing peptide receptors (GHSR), has been shown to stimulate the release of CRF and AVP by rat hypothalamic explants. However, little is known about the ability of the ghrelin signaling pathways to activate the CRF and AVP genes in the hypothalamus. In the present study, we examined the direct effect of ghrelin on CRF and AVP gene expression in hypothalamic 4B cells, which show the characteristics of the hypothalamic parvocellular paraventricular nucleus neurons. Cells were transfected with CRF or AVP promoter to examine the activity of each promoter. Ghrelin stimulated the promoter activities and mRNA levels for both CRF and AVP. The involvement of a protein kinase pathway was examined using inhibitors. Protein kinase A and phospholipase C pathways were shown to be involved in ghrelin-induced increases in both CRF and AVP promoter activities. GHSR type 1a (GHSR1a) mRNA levels were also increased by ghrelin, and these ghrelin-induced levels were suppressed by a GHSR1a antagonist. Thus, ghrelin-dependent pathways are involved in the regulation of CRF and AVP gene expression in the hypothalamus: ghrelin, an orexigenic hormone, stimulates CRF, an anorexigenic/anxiogenic factor in the hypothalamus, resulting in hypothalamic-pituitary-adrenal axis activation to stimulate the release of glucocorticoids.     

Can Jurors Free Themselves from Retributive Objectives?

We examined the hypothesis that the conscious self-correction process in the models of lay citizens’ determination of punishment could inhibit the retributive goal that was their instinctive default objective. In two experiments, we tested whether an instruction to ignore the retributive goal could eliminate the influence of information about the seriousness of the crime on the severity of the punishment. If the retributive goal can be inhibited, the instruction would eliminate the information’s influence on the punishment’s severity. However, the persistence of the information’s influence would mean that the retributive goal is not inhibited. The result showed that the instruction eliminated the influence of information that decreased the crime’s seriousness but could barely reduce the influence of information that increased the seriousness. We concluded that self-correction cannot inhibit the retributive goal when its inhibition would lead to a more lenient punishment.     

Information Seeking in a Non-Hypothesis Testing Task

The information gain model (Oaksford and Chater, Psychological Review 101, 608–631, 1994) advocates that participants attempt to achieve a larger expected information gain when they have to test an if-then rule or hypothesis. However, acquisition of larger expected information gain could also be operational when participants do not have to test a hypothesis. This study devised a new task to investigate whether participants would seek larger expected information gain when they were not required to test a hypothesis. The task required participants to select one out of two balance scales for weighing coins in order to detect an underweight coin. We discovered that participants more frequently selected the balance scale that provided smaller expected information gain. This finding suggests that the preference for larger expected information gain may not apply to non-hypothesis testing settings.     

Body Dissatisfaction,Need for Social Approval,and Eating Disturbances Among Japanese and American College Women

A total of 171 Japanese and 144 American collegewomen (90% European American, 4% African American, 4%Asian or Asian American, and 2% other) completed theEating Attitudes Test (EAT-26), the Body Dissatisfaction Subscale of the Eating Disorder Inventory(EDI), and the Revised Martin-Larsen Approval MotivationScale (MLAM). Japanese women expressed the greaterdissatisfaction with their body but no more eatingdisturbances than American women. The need for socialapproval predicted the Japanese women's eatingdisturbances after controlling for the effects of bodyfatness (BMI) and body dissatisfaction. BMI was asignificant predictor of eating disturbances for Americanwomen but not for Japanese women. The results werediscussed in terms of their implications forcross-cultural similarities and differences incorrelates of disordered eating.
