Cognitions and depressive symptoms among ethnic minority adolescents

Cognitive models have guided effective intervention strategies in the treatment of depression. However, little is known about the cognitive model's relevance in different cultural ethnic groups in the United States. This study examines the cross-sectional and longitudinal associations among cognitive variables and depressive symptoms among African American, Caucasian, and Hispanic adolescents in the United States. Community adolescents (N = 450) ages 14-18 years (African American n = 79; Caucasian n = 273; Hispanic n = 98) provided information regarding their depressive symptoms and cognitions at two surveys, 6 months apart. Self-efficacy, cognitive errors, and hopelessness were associated with concurrent depressive symptoms at baseline. In addition, cognitive errors at baseline, controlling for baseline depressive symptoms and the occurrence of stressful events, predicted depressive symptoms at follow-up. Ethnic differences disappeared when parent education level was controlled. Our findings demonstrate support for the cognitive model of depression across ethnic groups. The importance of controlling for social class when examining ethnic differences in psychological variables is highlighted by our findings.     

Cultural Lens on Mental Illness: Four Clients Share Their Perspectives

People served by mental health providers represent diverse cultural groups. In-depth qualitative interviews were used to collect data to examine: “How do people, diagnosed with a mental illness, perceive their experience in a partial care mental health program from the perspective of their cultural context?” Four participants described cultural identities that included ethnic, health status, and sexual orientation identities. The participants' way of participating in the world was often in conflict with cultural values and expectations of the family and counselors. Cultural competence must include understanding how complex, multiple cultural contexts interact and influence a person's participation in the therapeutic process.     

The influence of indirect and direct emotional processing on memory for facial expressions

We used the Remember–Know procedure (Tulving, 1985 Tulving, E. 1985. Memory and consciousness. Canadian Psychology, 26: 1–12. [Crossref], [Web of Science ®] , [Google Scholar]) to test the behavioural expression of memory following indirect and direct forms of emotional processing at encoding. Participants (N=32) viewed a series of facial expressions (happy, fearful, angry, and neutral) while performing tasks involving either indirect (gender discrimination) or direct (emotion discrimination) emotion processing. After a delay, participants completed a surprise recognition memory test. Our results revealed that indirect encoding of emotion produced enhanced memory for fearful faces whereas direct encoding of emotion produced enhanced memory for angry faces. In contrast, happy faces were better remembered than neutral faces after both indirect and direct encoding tasks. These findings suggest that fearful and angry faces benefit from a recollective advantage when they are encoded in a way that is consistent with the predictive nature of their threat. We propose that the broad memory advantage for happy faces may reflect a form of cognitive flexibility that is specific to positive emotions.     

Voice attractiveness: Influence of stimulus duration and type

Voice attractiveness is a relatively new area of research. Some aspects of the methodology used in this domain deserve particular attention. Especially, the duration of voice samples is often neglected as a factor and happens to be manipulated without the perceptual consequences of these manipulations being known. Moreover, the type of voice stimulus varies from a single vowel to complex sentences. The aim of this experiment was to investigate the extent to which stimulus duration (nonmanipulated vs. normalized) and type (vowel vs. word) influence perceived voice attractiveness. Twenty-seven male and female raters made attractiveness judgments of 30 male and female voice samples. Voice samples included a single vowel /a/, a three-vowel series /i a o/, and the French word “bonjour” (i.e., “hello”). These samples were presented in three conditions: nonmanipulated, shortened, and lengthened duration. Duration manipulation was performed using the pitch synchronous overlap and add (PSOLA) algorithm implemented in Praat. Results for the effect of stimulus type showed that word length samples were more attractive to the opposite sex than vowels. Results for the effect of duration showed that the nonmanipulated sound sample duration was not predictive of perceived attractiveness. Duration manipulation, on the other hand, altered perceived attractiveness for the lengthening condition. In particular, there was a linear decrease in attractiveness as a function of modification percentage (especially for the word, as compared with the vowels). Recommendations for voice sample normalization with the PSOLA algorithm are thus to prefer shortening over lengthening and, if not possible, to limit the extent of duration manipulation—for example, by normalizing to the mean sample duration.     

Childhood-Onset Multiple Sclerosis and Mood Disorders: A Case Study

Multiple Sclerosis (MS) is rare in children. Little research exists regarding emotional and behavioral disorders in childhood-onset MS, despite the occurrence of such problems in adults with MS. This paper describes the cognitive and behavioral characteristics of a boy diagnosed with MS at age 9 and mood disorder at age 10. He displayed no cognitive or behavioral problems prior to the onset of physical symptoms of MS. Three years after diagnosis, this child showed persistent problems with speed of processing, visual-motor skills, and parent and teacher-reported executive functioning. In addition, he had difficulties with emotional lability, behavioral disinhibition, depression, and social interaction. As with adults, children with MS may be at increased risk for mood disorder compared to their peers. Mood disorders in children with MS are likely to be multiply determined, although the specific causal mechanisms are unknown.     

The impact of depressive symptomatology on risky sexual behavior and sexual communication among African American female adolescents

Adolescents, particularly African American adolescents, are at high risk for sexually transmitted infections (STIs). The association between psychosocial factors and risky sexual behavior has been well established. However, only a small number of studies have examined the relationship between depressive symptomatology among African American female adolescents, specifically over time. The present study examined depressive symptoms as a predictor of risky sexual behavior, sexual communication, and STIs longitudinally among African American female adolescents between the ages 15 and 21. Binary generalized estimating equation models were conducted assessing the impact of depressive symptoms at baseline on risky sexual behavior and STIs over six- and 12-months follow-up. Age, intervention group, and baseline outcome measures were entered as covariates. The results indicated that high levels of depressive symptoms predicted no condom use during last sexual encounter and multiple sexual partners over six-months follow-up. Depressive symptoms also predicted having a main partner with concurrent partners, high fear of communication about condoms, and sex while high on alcohol or drugs over six- and 12-months follow-up. These findings could be used to inform HIV/STI prevention intervention programs and clinicians providing regular health care maintenance to African American female adolescents engaging in risky sexual behavior.     

A qualitative study of the impact of living with neurofibromatosis type 2

Neurofibromatosis type 2 (Nf2) is an inherited autosomal dominant syndrome characterised by the development of nervous system tumours, ocular abnormalities and skin tumours. Symptoms of Nf2 can vary depending on the size and location of the tumour and include hearing loss, balance deficits and facial palsy. This study explored the physical, emotional and social impact of Nf2. Six patients were recruited through a neurofibromatosis clinic and underwent a semi-structured interview. Interviews were recorded and analysed using Framework analysis. Participants spoke of the negative impact of Nf2 on daily activities, including work. Social isolation resulted from the avoidance of social situations and was often a consequence of difficulties with communication due to loss of hearing. Patients expressed a range of negative emotional reactions in response to their diagnosis and the impact of the disease. Furthermore, the findings highlighted the important role of partners and family who were relied on for physical as well as emotional and psychological support. Patients also expressed frustration at the limited awareness of Nf2 among health professionals and a desire for improved access to information on Nf2 within their local community.     

Retroactive adjustment of perceived time

Accurately timing acoustic events in dynamic scenes is fundamental to scene analysis. To detect events in busy scenes, listeners must often identify a change in the pattern of ongoing fluctuation, resulting in many ubiquitous events being detected later than when they occurred. This raises the question of how delayed detection time affects the manner in which such events are perceived relative to other events in the environment.To model these situations, we use sequences of tone-pips with a time–frequency pattern that changes from regular to random (‘REG–RAND’) or vice versa (‘RAND–REG’). REG–RAND transitions are detected rapidly, but the emergence of regularity cannot be established immediately, and thus RAND–REG transitions take significantly longer to detect. Using a temporal order judgment task, and a light-flash as a temporal marker, we demonstrate that listeners do not perceive the onset of RAND–REG transitions at the point of detection (∼530 ms post transition), but automatically re-adjust their estimate ∼300 ms closer to the nominal transition.These results demonstrate that the auditory system possesses mechanisms that survey the proximal history of an ongoing stimulus and automatically adjust perception to compensate for prolonged detection time, allowing listeners to build meaningful representations of the environment.     

Escape as reinforcement and escape extinction in the treatment of feeding problems

Given the effectiveness of putative escape extinction as treatment for feeding problems, it is surprising that little is known about the effects of escape as reinforcement for appropriate eating during treatment. In the current investigation, we examined the effectiveness of escape as reinforcement for mouth clean (a product measure of swallowing), escape as reinforcement for mouth clean plus escape extinction (EE), and EE alone as treatment for the food refusal of 5 children. Results were similar to those of previous studies, in that reinforcement alone did not result in increases in mouth clean or decreases in inappropriate behavior (e.g., Piazza, Patel, Gulotta, Sevin, & Layer, 2003). Increases in mouth clean and decreases in inappropriate behavior occurred when the therapist implemented EE independent of the presence or absence of reinforcement. Results are discussed in terms of the role of negative reinforcement in the etiology and treatment of feeding problems.
