Sudden changes in spectrum of an echo cause a breakdown of the precedence effect

The effect of changing the frequency components of an echo relative to the sound source was examined in a two-choice discrimination task. Subjects sat in an anechoic chamber and discriminated the direction of the lag noise burst within a lead-lag pair presented over loudspeakers. The leading noise burst was broadband, and the lagging burst was either high- or low-pass filtered. On some conditions, this test burst pair was preceded by a conditioning train of burst pairs, which also had a broadband lead and either a high- or low-frequency lag. When the frequency content of the echo was held constant across the conditioning train and test burst pair, echo suppression that was built up during the repeating train was maintained for the test burst pair, shown by the subjects’ poor performance in detecting the location of the lagging burst. By comparison, subjects had little difficulty in localizing the lagging burst when the frequency content of the echo changed between the conditioning train and the test burst, indicating that any buildup of suppression during the train was broken when the lagging burst’s spectrum shifted. The data are consistent with an interpretation in which echo suppression is temporarily broken when listeners’ built-up expectations about room acoustics are violated.     

Concept identification: Effect of the intertrial interval on the efficacy and consistency of information processing

Two experiments following identical procedure except for the feedback duration (respectively, 2 sec and 1.5 sec) and the intertrial interval (respectively, 1 sec and 3 sec) are compared with respect to three sequential statistics whose theoretical interpretation is related to the degree of optimality of information processing. The results indicate that the values of the theoretical parameters representing the efficiency of information processing, the consistency of trial-by-trial decisions, and the efficacy of reinforcement are greater in the 3-sec interval condition. This is interpreted as a tentative explanation of the well-known effect of intertrial interval on the difficulty of the task with respect to the mean number of trials to criterion.     

Recollections of Being in Child Expressive Arts Group Therapy: A Qualitative Study of Adult Former Clients’ Conceptions of Their Therapy as Children

The current study aims to explore, through the eyes of adult former clients, the experience of being in expressive arts group therapy (EAGT) as a child. By focusing on the memories of adults, the study allowed the exploration of former clients’ understanding of what the therapy was about and its effects on their lives. Semi-structured open-ended interviews were conducted with 20 adult former clients who, as children, had participated for at least one year in EAGT. Findings point toward the background of the empathic, attuned, safety, together with the fostering of the capacity to enter into spontaneous creative states, as central themes in participant’ recollections of the therapeutic process. Further findings relate to the implicit and long-term quality of the therapeutic effect.     

Coping with Abusive Supervision: the Neutralizing Effects of Perceived Organizational Support and Political Skill on Employees’ Burnout

While research into the antecedents of burnout has steadily grown, the relationship between abusive supervision and burnout remains largely unknown. In addition, we know little about the contingencies under which abusive supervision may be related to employees’ burnout. This study aims to examine the contingency side of the abusive supervision-burnout relationship by addressing the exploratory question of whether perceived organizational support and individual differences in political skill play moderating roles in the abusive supervision-burnout relationship. The present article developed a model and tested it with data from a sample of 248 supervisor–subordinate dyads. We hypothesized and found that (1) Abusive supervision was positively associated with burnout; (2) the positive relationship between abusive supervision and burnout was moderated by the employees’ perceived organizational support in such a way that the relationship was weaker for employees who perceive higher rather than lower organizational support; (3) the positive relationship between abusive supervision and burnout was moderated by the employees’ political skill in such a way that the relationship was weaker for people with high, rather than lower level of political skill.     

Family Expressiveness Mediates the Relation Between Cumulative Family Risks and Children’s Emotion Regulation in a Chinese Sample

Family expressiveness, a reflection of a family’s emotional environment, has been identified as a critical factor that influences children’s emotion regulation, yet research on this topic is limited, especially in varying cultural contexts. The present study addresses this research gap and expands on the extant literature by examining the influence of family expressiveness on children’s emotional development in the context of cumulative risks (e.g., low annual household income, parental psychological distress, parents’ education level, marital dissatisfaction and the family’s housing situation). Our final sample included one hundred and seventy-eight school-aged children (84 boys and 94 girls) and their biological parents. Results showed that higher scores on the familial risk index were related to increased emotion dysregulation and decreased adaptive emotion regulation, through the mediated effects of positive family expressiveness. Negative expressiveness, however, did not mediate the aforementioned links. Reasons for the different findings regarding positive expressiveness and negative expressiveness were discussed. These findings highlight the importance of cumulative risk on children’s emotional development in the Chinese cultural context and offer potential avenues to promote adaptive emotional development in the context of cumulative risks.     

Children’s Maternal Support-Seeking: Relations to Maternal Emotion Socialization Responses and Children’s Emotion Management

The present study examined children’s support-seeking of mothers (SSM) as a moderator of the association between maternal emotion socialization responses and children’s emotion management. Participants included 119 mother–child dyads (63 boys, M age = 9.61 years, 73.1 % Caucasian). Maternal emotion socialization was assessed via observed mother–child interactions and child report. Analyses indicated several main effects such that child-reported maternal reward responses were associated with stronger child emotion management, whereas perceived maternal punishment and neglect were associated with poorer child emotion management. Regarding the significant interactions, observed maternal general unsupportive socialization responses were negatively associated with emotion management. Additionally, for children low in SSM, child-reported maternal overriding of children’s emotions was positively associated with better emotion management. Support-seeking of mothers may mitigate the risk of some unsupportive maternal socialization responses and may be an adaptive strategy in middle childhood in particular contexts.     

Increasing Single‐Word Requests to Multiword Requests in Children with Autism and Related Disabilities

Initial language training with children with autism often focuses on the production of single‐word requests (i.e., mands). As a child progresses in treatment, it is desirable to increase the mean length of utterance (MLU) of requests. The present study examined treatment outcomes of behavioral intervention designed to increase the MLU of requests in a larger sample of children with language delays (n = 30). Intervention consisted of prompts and differential reinforcement for lengthier requests, and trials were conducted flexibly throughout the treatment session. A non‐concurrent multiple baseline across participants design was utilized to establish experimental control, and MLU intervention consisted of a baseline and treatment phase for each participant. Nonoverlap of all pairs (NAP) was employed to estimate an effect size. Overall treatment effects were medium to large (average NAP = 0.89; average d = 2.36), and the majority of the sample (70%) demonstrated strong treatment effects. Results suggest that targeted behavioral intervention to increase the length of requests can be effective for children with autism and associated language delays.

Coping styles in adults with cystic fibrosis: implications for emotional and social quality of life

As life expectancy increases, interest has grown surrounding the factors that may influence quality of life (QOL) for people with cystic fibrosis (CF). The aim of the current study was to examine which specific coping styles were positively or negatively associated with social and emotional QOL in a CF sample. One hundred and twenty-two respondents aged 18 and over were recruited through an online support group. Respondents completed the ‘CF Questionnaire-Revised (CFQ-R)’ and the ‘Brief COPE’. The CFQ-R is a disease-specific instrument designed to measure the impact of CF on nine QOL domains and the Brief COPE is a 28 item questionnaire which assesses 14 coping scales. A multivariate regression model revealed that higher substance abuse and disengagement was associated with lower emotional QOL whereas greater use of religion, instrumental coping and acceptance was positively associated with emotional QOL. Active coping was linked to better social QOL and a negative association was reported between distraction coping with both emotional and social domains. Given the burden of CF, ascertaining which factors enhance or diminish emotion and social well-being is now an integral component of QOL research. The current findings may therefore have value in informing clinical interventions which aim to cater for the psychological needs of individuals with CF.
