Lesion-symptom mapping of language impairments in people with brain tumours: The influence of linguistic stimuli

People with tumours in specific brain sites might face difficulties in tasks with different linguistic material. Previous lesion-symptom mapping studies (VLSM) demonstrated that people with tumours in posterior temporal regions have more severe linguistic impairments. However, to the best of our knowledge, preoperative performance and lesion location on tasks with different linguistic stimuli have not been examined. In the present study, we performed VLSM on 52 people with left gliomas to examine whether tumour distribution differs depending on the tasks of the Aachen Aphasia Test. The VLSM analysis revealed that single-word production (e.g. object naming) was associated with the inferior parietal lobe and that compound and sentence production were additionally associated with posterior temporal gyri. Word repetition was affected in people with tumours in inferior parietal areas, whereas sentence repetition was the only task to be associated with frontal regions. Subcortically, word and sentence production were found to be affected in people with tumours reaching the arcuate fasciculus, and compound production was primarily associated with tumours affecting the inferior longitudinal and inferior fronto-occipital fasciculus. Our work shows that tasks with linguistic stimuli other than single-word naming (e.g. compound and sentence production) relate to additional cortical and subcortical brain areas. At a clinical level, we show that tasks that target the same processes (e.g. repetition) can have different neural correlates depending on the linguistic stimuli used. Also, we highlight the importance of left temporoparietal areas.     

Disenfranchised Grief Following a Traumatic Birth

Following a “failed” birth plan, some women experience trauma. Because most of these women do end up with a healthy baby, their support system does not necessarily support the sadness felt at the loss of the dream birth experience, leading to disenfranchised grief. Comments on a Facebook post linked to an essay from the Scary Mommy website were examined. Thematic analysis revealed three overarching categories of comments: (a) grief is disenfranchised by others through nonlosses and one-upping; (b) other posters expressed camaraderie for the loss of a dream birth, expressing empathy; and, (c) conditional support.     

Two Steps Forward,One Step Back: The Presence of Female Characters and Gender Stereotyping in Award-Winning Picture Books Between the 1930s and the 1960s

Since the late 1960s, there has been steady, progressive change in the depiction of gender in award-winning picture books for children (e.g., Clark, Almeida, Gurka, & Middleton, 2003). Female characters in Caldecott winners and runners-up have become increasingly visible and gender stereotyping has become decreasingly evident. In this article we consider whether this steady change can be projected back into the decades before the 1960s, or whether local, temporal variation in gender norms affected less monotonic change. We found that Caldecotts of the late 1940s and the late 1960s had fewer visible female characters than Caldecotts of the late 1930s and the late 1950s, but that characters in the 1940s and 1960s were less gender stereotyped than the characters of the 1930s and 1950s. We interpret these findings in terms of the greater level of conflict over gender roles that existed in the 1940s and 1960s, as well as the relatively greater status enjoyed by American women in those decades.     

Configural face encoding and spatial frequency information

Configural relations and a critical band of spatial frequencies (SFs) in the middle range are particularly important for face recognition. We report the results of four experiments in which the relationship between these two types of information was examined. In Experiments 1, 2A, and 2B, the face inversion effect (FIE) was used to probe configural face encoding. Recognition of upright and inverted faces and nonface objects was measured in four conditions: a no-filter condition and three SF conditions (low, medium, and high frequency). We found significant FIEs of comparable magnitudes for all frequency conditions. In Experiment 3, discrimination of faces on the basis of either configural or featural modifications was measured under the same four conditions. Although the ability to discriminate configural modifications was superior in the medium-frequency condition, so was the ability to discriminate featural modifications. We conclude that the band of SF that is critical for face recognition does not contribute preferentially to configural encoding.     

Sex,Power, and Money: Prediction from the Dark Triad and Honesty–Humility

Data were collected from two undergraduate student samples to examine (i) the relations of the ‘Dark Triad’ variables (Machiavellianism, Psychopathy, and Narcissism) with the HEXACO personality dimensions, as well as (ii) the ability of the aforementioned characteristics and of the Big Five personality factors to predict outcome variables related to sex, power, and money. Results indicated that the common variance of the Dark Triad was very highly correlated with low Honesty–Humility and that the unique variance of each of the Dark Triad variables also showed theoretically meaningful relations with the other five HEXACO factors. Furthermore, the Dark Triad and Honesty–Humility were strong predictors of three domains of outcome variables—Sex (short‐term mating tendencies and sexual quid pro quos), Power (Social Dominance Orientation and desire for power), and Money (conspicuous consumption and materialism)—that were not well predicted by the dimensions of the Big Five.
