Change detection in complex scenes: hemispheric contribution and the role of perceptual and semantic factors

The perceptual salience and semantic relevance of objects for the meaning of a scene were evaluated with multiple criteria and then manipulated in a change-detection experiment that used an original combination of one-shot and tachistoscopic divided-visual-field paradigms to study behavioural hemispheric asymmetry. Coloured drawings that depicted meaningful situations were presented centrally and very briefly (120 ms) and only the changes were lateralised by adding an object in the right or in the left visual hemifield. High salience and high relevance improved both response times (RTs) and accuracy, although the overall contribution of salience was greater than that of relevance. Moreover, only for low-salience changes did relevance affect speed. RTs were shorter when a change occurred in the left visual hemifield, suggesting a right-hemisphere advantage for detection of visual change. Also, men responded faster than women. The theoretical and methodological implications are discussed.     

Children's activities and their meanings for parents: a mixed-methods study in six Western cultures

Theoretical perspectives and research in sociology, anthropology, sociolinguistics, and cultural psychology converge in recognizing the significance of children's time spent in various activities, especially in the family context. Knowing how children's time is deployed, however, only gives us a partial answer to how children acquire competence; the other part must take into account the culturally constructed meanings of activities, from the perspective of those who organize and direct children's daily lives. In this article, we report on a study of children's routine daily activities and on the meanings that parents attribute to them in six Western middle-class cultural communities located in Italy, The Netherlands, Poland, Spain, Sweden, and the United States (N = 183). Using week-long time diaries kept by parents, we first demonstrate similarities as well as significant differences in children's daily routines across the cultural samples. We then present brief vignettes--"a day in the life" --of children from each sample. Parent interviews were coded for themes in the meanings attributed to various activities. Excerpts from parent interviews, focusing on four major activities (meals, family time, play, school- or developmentally related activities), are presented to illustrate how cultural meanings and themes are woven into parents' organization and understanding of their children's daily lives. The results of this mixed-method approach provide a more reliable and nuanced picture of children's and families' daily lives than could be derived from either method alone.     

Women accused of sex offenses: a gender-based comparison

Sexual offenses committed by women are likely underestimated and under-reported. This exploratory study compares and contrasts women accused of sexual offenses and their male counterparts. Data were retrospectively compiled on all alleged female and age-matched male sex offenders who were referred for psychiatric evaluation to a large Midwestern city's court psychiatric clinic over a six-year period. Data were abstracted regarding their crimes, charges, demographics, social history, medical history, legal history, violence history, substance use, sexual history, psychiatric history and their victims. Like the men, women were most frequently referred for sexual predator classification evaluations. Ages ranged from 19 to 62 years, and the majority had children. Most had prior arrests. One-third had a past history of psychiatric hospitalization, and most were given a non-paraphilic psychiatric diagnosis. The majority of the women reported past histories of sexual or physical victimization. While there were many similarities between female and male sex offenders in this psychiatric sample, women more frequently had victims of both genders.     

Sticky thoughts: depression and rumination are associated with difficulties manipulating emotional material in working memory

Cognitive inflexibility may play an important role in rumination, a risk factor for the onset and maintenance of depressive episodes. In the study reported here, we assessed participants' ability to either reverse or maintain in working memory the order of three emotion or three neutral words. Differences (or sorting costs) between response latencies in backward trials, on which participants were asked to reverse the order of the words, and forward trials, on which participants were asked to remember the words in the order in which they were presented, were calculated. Compared with control participants, depressed participants had higher sorting costs, particularly when presented with negative words. It is important to note that rumination predicted sorting costs for negative words but not for positive or neutral words in the depressed group. These findings indicate that depression and rumination are associated with deficits in cognitive control.     

The Relationship Quality Interview: evidence of reliability, convergent and divergent validity, and incremental utility

Relationship satisfaction and adjustment have been the target outcome variables for almost all couple research and therapies. In contrast, far less attention has been paid to the assessment of relationship quality. The present study introduces the Relationship Quality Interview (RQI), a semistructured, behaviorally anchored individual interview. The RQI was designed to provide a more objective assessment of relationship quality as a dynamic, dyadic construct across 5 dimensions: (a) quality of emotional intimacy in the relationship, (b) quality of the couple's sexual relationship, (c) quality of support transactions in the relationship, (d) quality of the couple's ability to share power in the relationship, and (e) quality of conflict/problem-solving interactions in the relationship. Psychometric properties of RQI ratings were examined through scores obtained from self-report questionnaires and behavioral observation data collected cross-sectionally from a sample of 91 dating participants and longitudinally from a sample of 101 married couples. RQI ratings demonstrated strong reliability (internal consistency, interrater agreement, interpartner agreement, and correlations among scales), convergent validity (correlations between RQI scale ratings and questionnaire scores assessing similar domains of relationship quality), and divergent validity (correlations between RQI scale ratings and (a) behavioral observation codes assessing related constructs, (b) global relationship satisfaction scores, and (c) scores on individual difference measures of related constructs). Clinical implications of the RQI for improving couple assessment and interventions are discussed.     

The use of response cost to treat spitting by a child with autism

We evaluated the extent to which noncontingent access to one or multiple items and the contingent removal of a specific item decreased a young boy's spitting. Results indicated that the boy's spitting did not decrease when he was given noncontingent access to multiple, alternative stimuli or to a toy radio. By contrast, when the toy radio was removed contingent on spitting, the rate of the boy's spitting decreased to zero or near‐zero levels. Similar results were produced in the boy's special education classroom. Follow‐up sessions conducted 2 and 4 months later indicated that the reduction in the boy's spitting persisted across time.

Depression is not an inevitable outcome of disclosure avoidance: HIV stigma and mental health in a cohort of HIV-infected individuals from Southern India

Previous research has shown that HIV stigma in India can be characterized by a framework dividing manifestations into enacted (discrimination), vicarious (hearing stories of discrimination), felt normative (perceptions of stigma's prevalence), and internalized stigma (personal endorsement of stigma beliefs). We examined whether this framework could explain associations among stigma, efforts to avoid HIV serostatus disclosure, and depression symptoms in a cohort of 198 HIV-infected individuals from Southern India who were followed up for one year as part of a study of antiretroviral adherence. Prior studies had suggested that disclosure avoidance was a primary outcome of stigma and that impaired well-being was a primary outcome of disclosure avoidance. Analyses from our longitudinal research revealed that the pattern of associations among stigma, disclosure avoidance, and depression symptoms remained consistent over time. Enacted and vicarious stigmas were correlated with felt normative stigma beliefs. In turn, felt normative stigma was correlated with disclosure avoidance. And, enacted stigma, internalized stigma, and disclosure avoidance were all associated with depression symptoms. However, even though the overall framework held together, internalized stigma and depression symptoms dropped significantly over time while other components remained unchanged. These findings suggest that, although HIV stigma may limit disclosure, it does not invariably lead to psychological maladjustment. Amidst ongoing perceptions and experiences of stigma, HIV-positive individuals can achieve significant improvements in their acceptance of the disease and in mental well-being.     

Association Between Insomnia and Quality of Life: An Exploratory Study Among Software Engineers

Insomnia is a major public health challenge. Due to its high prevalence and impact on health in recent years it has attracted attention of health care providers. The concept of quality of life (QOL) has gained importance as an outcome measure in sleep disturbed people. This study aims to determine the prevalence of insomnia among software engineers as the job related stress is considered very high. Ninety-one software engineers aged between 21 and 45 from a software developing company in Mysore formed the study population. Insomnia Screening Questionnaire and SF 36 Health Survey Questionnaire were used to elicit information about sleep quality and quality of life respectively. Sleep status among the subjects was as follows: 20.9% severe insomnia, 35.2% mild insomnia and 43.9% normal sleeper. Mean scores for SF 36 and those for physical and mental health were considerably lower among severe insomniacs. Software engineers run at the risk of developing insomnia, those with severe insomnia had poor QOL in comparison with the others. Quality of sleep among software engineers needs special attention since they are prone to develop sleep disturbances.     

On authenticity: the question of truth in construction and autobiography

Freud was occupied with the question of truth and its verification throughout his work. He looked to archaeology for an evidence model to support his ideas on reconstruction. He also referred to literature regarding truth in reconstruction, where he saw shifts between historical fact and invention, and detected such swings in his own case histories. In his late work Freud pondered over the impossibility of truth in reconstruction by juxtaposing truth with ‘probability’. Developments on the role of fantasy and myth in reconstruction and contemporary debates over objectivity have increasingly highlighted the question of ‘truth’ in psychoanalysis. I will argue that ‘authenticity’ is a helpful concept in furthering the discussion over truth in reconstruction. Authenticity denotes that which is genuine, trustworthy and emotionally accurate in a reconstruction, as observed within the immediacy of the analyst/patient interaction. As authenticity signifies genuineness in a contemporary context its origins are verifiable through the analyst’s own observations of the analytic process itself. Therefore, authenticity is about the likelihood and approximation of historical truth rather than its certainty. In that respect it links with Freud’s musings over ‘probability’. Developments on writing ‘truths’ in autobiography mirror those in reconstruction, and lend corroborative support from another source.     

Can I trust you? Negative affective priming influences social judgments in schizophrenia

Successful social interactions rely on the ability to make accurate judgments based on social cues as well as the ability to control the influence of internal or external affective information on those judgments. Prior research suggests that individuals with schizophrenia misinterpret social stimuli and this misinterpretation contributes to impaired social functioning. We tested the hypothesis that for people with schizophrenia, social judgments are abnormally influenced by affective information. Twenty-three patients with schizophrenia and 35 healthy control participants rated the trustworthiness of faces following the presentation of neutral, negative (threat-related), or positive affective primes. Results showed that all participants rated faces following negative affective primes as less trustworthy than faces following neutral or positive primes. Importantly, this effect was significantly more pronounced for participants with schizophrenia, suggesting that schizophrenia may be characterized by an exaggerated influence of negative affective information on social judgment. Furthermore, the extent that the negative affective prime influenced trustworthiness judgments was significantly associated with patients' severity of positive symptoms, particularly feelings of persecution. These findings suggest that for people with schizophrenia, negative affective information contributes to an interpretive bias, consistent with paranoid ideation, when judging the trustworthiness of others. This bias may contribute to social impairments in schizophrenia.
