Factors Associated with Support for Adolescent Access to Contraception Among Mexican Catholic Parents

Anxiety and depression and their links with delusions and hallucinations in people with a dual diagnosis of psychosis and substance misuse: a study using data from a randomised controlled trial

Rates of depression and anxiety have been linked to severity and distress associated with positive symptoms in psychosis. There is also tentative evidence to suggest that these concurrent symptoms might be related to delusional and hallucinatory content. Our aim was to assess the cross-sectional associations between anxiety and depression, and hallucination and delusion severity and distress in a sample of 327 people dually diagnosed with psychosis and substance misuse problems. In addition, the relationships between specific symptom content and levels of anxiety and depression were examined. Anxiety was associated with delusion distress and depression with hallucination distress, although neither was related to symptom severity. Auditory commands to harm or kill the self were associated with higher levels of depression. Delusions with themes pertaining to the paranormal, and those with references to celebrities were associated with lower levels of depression. No specific delusion or hallucination content was associated with level of anxiety, when other variables were controlled for. The results demonstrate that anxiety and depression are linked to distinct aspects of psychotic experience, highlighting the need to acknowledge the role of these concurrent symptoms in the context of psychosis. In addition, findings relating to specific types of delusions and hallucinations highlight avenues for further research.     

Concurrent drinking and smoking among college students: An event-level analysis

Cigarette smoking and drinking commonly co-occur among college students, a population that is at high risk for developing alcohol and nicotine use disorders. Several studies have been conducted that have examined predictors of drinking or smoking to gain a better understanding of the antecedents of engaging in these behaviors. Yet, few studies have examined specific factors that influence concurrent smoking and drinking in this population. The current study used data from a 21-day electronic diary-based study of college students (n=86) who engaged in concurrent drinking and smoking to examine event-level associations between alcohol use and cigarette smoking in the student's natural environment. We specifically focused on within-person analyses of contexts in which students reported smoking and drinking simultaneously in comparison to contexts in which students reporting drinking without smoking. Situational contexts included environmental setting, whether s/he was alone or with others, and changes in stress and urges to smoke before initiating drinking. Results indicated that students drank more while smoking and smoked three times as many cigarettes, on average, during drinking episodes. Being with others at a party or a bar was associated with increased odds of smoking while drinking. Likewise, increased stress since the prior assessment predicted a greater likelihood of smoking while drinking. Based on the findings from the present study, it is important for future prevention and intervention efforts to consider social settings and heightened stress among students as potential risk factors for engaging in concurrent drinking and smoking.     

Processing orientation and emotion recognition

There is evidence that some emotional expressions are characterized by diagnostic cues from individual face features. For example, an upturned mouth is indicative of happiness, whereas a furrowed brow is associated with anger. The current investigation explored whether motivating people to perceive stimuli in a local (i.e., feature-based) rather than global (i.e., holistic) processing orientation was advantageous for recognizing emotional facial expressions. Participants classified emotional faces while primed with local and global processing orientations, via a Navon letter task. Contrary to previous findings for identity recognition, the current findings are indicative of a modest advantage for face emotion recognition under conditions of local processing orientation. When primed with a local processing orientation, participants performed both significantly faster and more accurately on an emotion recognition task than when they were primed with a global processing orientation. The impacts of this finding for theories of emotion recognition and face processing are considered.     

Gender differences in children's divergent thinking

Block's theory (1984) of gender differences was examined to determine if it could explain inconsistencies in the reports of gender differences and the personality correlates of creativity in children. Additionally, an investigation of 244 gifted children in grades 4 to 8 is described. Two divergent thinking tests, each with a familiar and an unfamiliar item, were used to test cognitive style. The Dependency Proneness Test was used to measure independence, and the Fundamental Interpersonal Relations Orientation‐Behavior Children was used to measure social orientation. No gender differences were found on the measures of personality and cognitive style, and no significant association was found between cognitive style and personality. The results were discussed in light of the moderating influence of sex‐role flexibility and the relative freedom boys and girls experience in peer groups and play.     

A Look Beyond the Mirror—What He Saw and I Didn't: Reply to Commentary

Altman's commentary challenged this author on both a personal and a theoretical level. On a personal level, she was encouraged to explore her knowing at one moment but not knowing at another, her own self-interest in the position of beneficiary. Thus, the mechanism of disavowal that underpins liberal racism was revisited in a more clinically oriented manner.

On a theoretical level, Altman's response invited a more refined exploration of liberal racism as it differs from blatant racism. It also facilitated a more nuanced application of Lacanian and Kleinian theory to this matter.     

High perceptual load causes inattentional blindness and deafness in drivers

ABSTRACT

Perceptual load theory of attention predicts that the level of perceptual load in a primary task affects the processing of additional stimuli. Given the lack of ecologically valid evidence for the model, the current study assessed the effect of perceptual load on driver awareness during simulated driving tasks. The results showed that perceptual load dramatically affected driver awareness for visual and auditory stimuli, even those that were driving relevant and safety critical (e.g. pedestrians or the sound of a car horn). The results support load theory and suggest that perceptual load may be an important factor in driver safety.     

Atypical updating of face representations with experience in children with autism

Face identity aftereffects are significantly diminished in children with autism relative to typical children, which may reflect reduced perceptual updating with experience. Here, we investigated whether this atypicality also extends to non‐face stimulus categories, which might signal a pervasive visual processing difference in individuals with autism. We used a figural aftereffect task to measure directly perceptual updating following exposure to distorted upright faces, inverted faces and cars, in typical children and children with autism. A size‐change between study and test stimuli limited the likelihood that any processing atypicalities reflected group differences in adaptation to low‐level features of the stimuli. Results indicated that, relative to typical children, figural aftereffects for upright faces, but not inverted faces or cars, were significantly attenuated in children with autism. Moreover, the group difference was amplified when we isolated the ‘face‐selective’ component of the aftereffect, by partialling out the mid‐level shape adaptation common to upright and inverted face stimuli. Notably, the aftereffects of typical children were disproportionately larger for upright faces than for inverted faces and cars, but the magnitude of aftereffects of autistic children was not similarly modulated according to stimulus category. These findings are inconsistent with a pervasive adaptive coding atypicality relative to typical children, and suggest that reduced perceptual updating may constitute a high‐level, and possibly face‐selective, visual processing difference in children with autism.
