Metacognitive Ability and Test Performance Among College Students

We studied college students' metacognitive ability to see whether or to what extent it would be correlated with actual test grades. We hypothesized that higher metacognitive ability would correlate with higher exam marks and that lower metacognitive ability would correlate with lower exam marks. College students (N = 109) were asked to guess the grade they expected to receive at the completion of a regular classroom exam. We found a significant negative correlation between the actual grade received, a measure of cognitive ability, and the difference between the actual grade and the expected grade, a measure of metacognitive ability.     

Positive expectancies and perceived impaired control mediate the influence of reward drive and rash impulsiveness on alcohol use

Recent factor analytic studies indicate that the broad trait of impulsivity comprises at least two distinct dimensions with regard to substance use. Thus, a two-factor model of impulsivity, comprising reward drive (i.e., sensitivity to rewarding stimuli) and rash impulsiveness (i.e., rash behaviour devoid of forethought), has been proposed. It is argued that distinct cognitive processes may mediate the association of these impulsivity factors with alcohol use. Specifically, it was hypothesised that drinking expectancies would mediate the association between reward drive and alcohol use, and that perceived impaired control would mediate the effect of rash impulsiveness on alcohol. Utilising established scales, 132 participants aged 18 to 70 years were surveyed in order to assess the capacity of the two-factor model to differentially predict alcohol use through distinct cognitive mediators. The hypotheses were supported, providing support for a two-factor approach. Thus, reward drive and rash impulsiveness appear to influence alcohol use through distinct cognitive processes.     

Edgar Allan Poe: A psychological profile

Edgar Allan Poe is often regarded as one of the most well-known American poets of the 19th century. He is best known for his dark, gruesome depictions of emotionally haunted characters. His most famous poem, The Raven, exemplifies this style. To understand what motivated this writing style, we must learn about the man behind the pen. Not surprisingly, Poe had a difficult upbringing, fraught with illness, loss, and poverty. This review will examine Poe’s personal life and discuss how early experiences and possible genetic predispositions may have contributed to his affect and behaviours as an adult.     

Examining the Development of Attention and Executive Functions in Children With a Novel Paradigm

The development of attention and executive functions in normal children (7–12 years) was investigated using a novel selective reaching task, which involved reaching as rapidly as possible towards a target, while at times having to ignore a distractor. The information processing paradigm allowed the measurement of various distinct dimensions of behaviour within a single task. The largest improvements in vigilance, set-shifting, response inhibition, selective attention, and impulsive responding were observed to occur between the ages of 8 and 10, with a plateau in performance between 10 and 12 years of age. These findings, consistent with a step-wise model of development, coincide with the observed developmental spurt in frontal brain functions between 7 and 10 years of age, and indicate that attention and executive functions develop in parallel. This task appears to be a useful research tool in the assessment of attention and executive functions, within a single task. Thus it may have a role in determining which cognitive functions are most affected in different childhood disorders.     

Facial memory deficits in children with fetal alcohol spectrum disorders

Prenatal exposure to alcohol may lead to a range of neurobehavioral effects, including impaired learning and memory. Although children with fetal alcohol spectrum disorders (FASD) exhibit both verbal and nonverbal memory impairments, their memory for faces has not been as thoroughly investigated and the extent literature provides inconsistent results. The aim of the current study was to determine whether difficulties in face memory exist in children with FASD and whether the difficulties are mediated by task demands. To address this, we used two measures of immediate and delayed facial recognition memory, the Children's Memory Scale (CMS) and Test of Memory and Learning (TOMAL). Compared to typically developing controls, children with FASD showed memory deficits on all tests and were more likely to perform in a clinically significant range. As well, children performed more poorly on the CMS compared to TOMAL, a finding consistent with the greater difficulty of the CMS task. Our results are consistent with our hypothesis that children with FASD show impairment in facial memory, particularly on demanding memory tasks.     

Improving executive functioning in children with fetal alcohol spectrum disorders

An extensive body of literature has documented executive function (EF) impairments in children with fetal alcohol spectrum disorders (FASD); however, few studies have aimed specifically at improving EF. One treatment program that shows promise for children with FASD is the Alert Program for Self-Regulation®, which is a 12-week treatment specifically designed to target self-regulation, a component of EF. The present study sought to examine if Alert would produce improvements in self-regulation that would generalize to other aspects of EF, behavior, and social skills in children with FASD. Twenty-five children aged 8–12 years diagnosed with an FASD were assigned in alternating sequence to either an immediate treatment (TXT) or a delayed treatment control (DTC) group. Both groups received a comprehensive evaluation of EF at baseline and upon completing therapy (TXT), or after a 12- to 14-week interval from baseline (DTC). Parents also completed questionnaires assessing EF and behavior at both time points. For the TXT group only, parent questionnaires were readministered at 6-month follow-up. At the 12-week follow-up, the TXT group displayed significant improvements in inhibitory control and social cognition. Parents of children in the TXT group reported improved behavioral and emotional regulation, as well as reduced externalizing behavior problems. These behavioral improvements along with further improved parent-rated inhibitory control was maintained at the 6-month follow-up. The EF disabilities in children with FASD can be remediated through a targeted treatment approach aimed at facilitating self-regulation skills.     

Some effects of alcohol and eye movements on cross-race face learning

This study examines the impact of acute alcohol intoxication on visual scanning in cross-race face learning. The eye movements of a group of white British participants were recorded as they encoded a series of own-and different-race faces, under alcohol and placebo conditions. Intoxication reduced the rate and extent of visual scanning during face encoding, reorienting the focus of foveal attention away from the eyes and towards the nose. Differences in encoding eye movements also varied between own-and different-race face conditions as a function of alcohol. Fixations to both face types were less frequent and more lingering following intoxication, but in the placebo condition this was only the case for different-race faces. While reducing visual scanning, however, alcohol had no adverse effect on memory, only encoding restrictions associated with sober different-race face processing led to poorer recognition. These results support perceptual expertise accounts of own-race face processing, but suggest the adverse effects of alcohol on face learning published previously are not caused by foveal encoding restrictions. The implications of these findings for alcohol myopia theory are discussed.     

Alexithymia and aspects of dreaming: Differential associations of alexithymia facets with dream variables

Research on aspects of dreaming associated with alexithymia has yielded mixed results. The present study recruited a young adult online sample of 577 participants who completed validated indices of alexithymia, emotion suppression, negative moods, and eight aspects of dreaming, with a focus on evaluating a counterintuitive previous finding that alexithymia and two of its core facets were associated with greater self-reported typical emotional intensity of dreams. Total alexithymia and facet scores showed differential relationships to aspects of dreaming including dream recall frequency, emotionality, meaningfulness, nightmare frequency, nightmare distress, usefulness of dreams in problem-solving and creativity, and learning about oneself through dreams. Planned hierarchical regression controlling for demographics, alcohol use, and dream recall frequency indicated that the difficulties identifying feelings (DIF) facet of alexithymia was a significant positive predictor of dream emotionality, whereas the externally oriented thinking (EOT) facet was a significant negative predictor. Stress, but not emotion suppression, mediated the positive relationship between DIF and dream emotionality. The likely role of dream emotionality in higher ratings of nightmare distress, dream meaningfulness, and learning about oneself through dreams among those with higher DIF scores is noted, along with other findings and the strengths and limitations of the study.     

Experiences of Patients in Cognitive Behavioural Group Therapy: A Qualitative Study of Eating Disorders

The aim of this study was to investigate whether there was a difference in skin conductance response between 2 groups of military personnel when exposed to emotionally neutral and charged stimuli. The 2 groups were a combat experience group (n?=?10) with prior experience of emotionally charged war situations and a comparison group (n?=?10) with no such experience. Results showed that the comparison group reacted more strongly to exposure to both charged and neutral pictures than did the combat experience group, regardless of exposure time. The results are discussed in terms of emotional numbing and differences in anxiety state between the 2 groups.     

Hazardous Alcohol Use among Persons Living with Human Immunodeficiency Virus Infection in the Eastern Cape,South Africa

The study assessed the prevalence of hazardous alcohol use among people living with HIV (PLHIV) and its correlates with socio-economic characteristics, disease variables and ART adherence in South Africa. The sample included 607 PLHIV (males =475, females =132; age range =18–61), sampled by all districts in the Eastern Cape. Participants were recruited through a health facility in the community through key informants or a support group. Results indicate that male PLHIV were more often than female PLHIV “past month” (18.9% vs. 6.1%) and hazardous alcohol drinkers (6.1% vs. 2.7%); using a cut-off score of 8 and more on the Alcohol Use Disorders Identification Test (AUDIT). Not having a disability grant for HIV/AIDS and the disability grant terminated were both related to past month alcohol use, while having the “disability grant stopped” was also related with hazardous or harmful drinking. Not having an AIDS diagnosis and not being on ART were both associated with past month alcohol use and hazardous or harmful drinking. CD4 counts and non-adherence to ART were both not significantly related with alcohol use status. Brief health provider initiated alcohol interventions for PLHIV should be promoted, with emphasis on targeting men.
