Proneness to psychosis and selection of objects of visual attention: individual differences in visual marking

Deficits in early visual attention and perceptual organisation have frequently been shown to associate with both poor pre-morbid schizophrenia and those at a greater putative risk of psychosis. The nature of the deficit is unclear. The present study investigated the relationship between speed of visual marking and proneness to psychosis. 20 males and 20 females completed several tasks assessing speed of selection and de-selection of visual objects. As predicted, negative schizotypy was associated with poorer marking in males, but socially desirable responding potentially confounded this result. In addition, impulsive non-conformity swas associated with poorer visual marking, more prominently in females. These results are discussed in relation to possible mechanisms by which psychosis-proneness and impulsivity may restrict the top–down influences operating on early visual attention.     

Belief is Contingently Involuntary

The debate between “Normativists” and “Teleologists” about the normativity of belief has been taken to hinge on the question of which of the two views best explains why it is that we cannot (non‐contingently) believe at will. Of course, this presupposes that there is an explanation to be had. Here, I argue that this supposition is unwarranted, that Doxastic Involuntarism is merely contingently true. I argue that this is made apparent when we consider that suspended judgement must be involuntary if belief is, that suspended judgment is not a belief (or set of beliefs), and that the aim or norm of suspended judgement cannot be constitutive if suspended judgement is not a belief (or set of beliefs).     

Spatial and reversal learning in the Morris water maze are largely resistant to six hours of REM sleep deprivation following training

This first test of the role of REM (rapid eye movement) sleep in reversal spatial learning is also the first attempt to replicate a much cited pair of papers reporting that REM sleep deprivation impairs the consolidation of initial spatial learning in the Morris water maze. We hypothesized that REM sleep deprivation following training would impair both hippocampus-dependent spatial learning and learning a new target location within a familiar environment: reversal learning. A 6-d protocol was divided into the initial spatial learning phase (3.5 d) immediately followed by the reversal phase (2.5 d). During the 6 h following four or 12 training trials/day of initial or reversal learning phases, REM sleep was eliminated and non-REM sleep left intact using the multiple inverted flowerpot method. Contrary to our hypotheses, REM sleep deprivation during four or 12 trials/day of initial spatial or reversal learning did not affect training performance. However, some probe trial measures indicated REM sleep-deprivation-associated impairment in initial spatial learning with four trials/day and enhancement of subsequent reversal learning. In naive animals, REM sleep deprivation during normal initial spatial learning was followed by a lack of preference for the subsequent reversal platform location during the probe. Our findings contradict reports that REM sleep is essential for spatial learning in the Morris water maze and newly reveal that short periods of REM sleep deprivation do not impair concurrent reversal learning. Effects on subsequent reversal learning are consistent with the idea that REM sleep serves the consolidation of incompletely learned items.     

Differences in Career and Life Planning Between African American and Caucasian Undergraduate Women

Women, especially African American women, have traditionally been in low‐paying careers. This exploratory study examined how career aspirations are affected by future career and family plans. Results revealed that African American undergraduate women had higher career aspirations than Caucasian undergraduate women and also planned for multiple roles in the future. Las mujeres, sobre todo las mujeres Afroamericanas, han desarrollado tradicionalmente sus carreras en trabajos de menor remuneración. Este estudio exploratorio examinó cómo las aspiraciones de carrera son afectadas por los planes futuros de carrera y familia. Los resultados revelaron que las estudiantes universitarias Afroamericanas tenían aspiraciones de carrera más elevadas que las estudiantes Caucásicas, y también planeaban tener múltiples roles en el futuro.     

Differential prefrontal–temporal neural correlates of semantic processing in children

This study used functional magnetic resonance imaging (fMRI) to examine brain–behavior correlations in a group of 16 children (9- to 12-year-olds). Activation was measured during a semantic judgment task presented in either the visual or auditory modality that required the individual to determine whether a final word was related in meaning to one of two previous words (e.g., found–tank–lost). The main finding was that higher performers (i.e., accuracy) were associated with more activation in posterior representational systems including the inferior and middle temporal gyri, whereas lower performers were associated with more activation in anterior regions including the inferior and middle frontal gyri. This pattern of results was interpreted as reflecting an elaborated semantic representational system in temporal areas for the high accuracy performers that allowed them to efficiently and accurately make meaning based judgments. The low accuracy performers may have an inaccurate or weakly interconnected semantic system that results in greater use of frontal areas in a feature selection process.     

Brain lateralization of phonological awareness varies by maternal education

Socioeconomic status (SES) has been shown to influence language skills, with children of lower SES backgrounds performing worse on language assessments compared to their higher SES peers. While there is abundant behavioral research on the effects of SES, whether there are differences in the neural mechanisms used to support language skill is less established. In this study, we examined the relation between maternal education (ME), a component of SES, and neural mechanisms of language. We focused on Kindergarten children, at the beginning of formal reading education, and on a pre‐reading skill, phonological awareness—the ability to distinguish or manipulate the sounds of language. We determined ME‐related differences in neural activity by examining a skill‐matched sample of typically achieving 5‐year‐old children as they performed a rhyme judgment task. We examined brain lateralization in two language processing regions, the inferior frontal gyrus (IFG) and superior temporal gyrus (STG). In the IFG, lateralization was related to ME but not skill: children with low ME showed bilateral activation compared to children with higher ME who showed leftward lateralization. In the STG, there was a skill by ME interaction on lateralization, such that children with high ME showed a positive relation between rightward lateralization and skill and children with low ME showed a positive relation between leftward lateralization and skill. Thus, we demonstrated ME is related to differences in neural recruitment during language processing, yet this difference in recruitment is not indicative of a deficit in linguistic processing in Kindergarten children.     

Establishing an Alcohol and Other Drug Assessment and Intervention Program Within an On‐Site Counselor Education Research and Training Clinic

The authors describe the Substance Information Program, a university alcohol and other drug (AOD) assessment and intervention program. The Substance Information Program is housed in a counseling department's on‐site training and research clinic and gives counselors‐in‐training an opportunity to gain practical addictions training.
