Rearing practices and impulsivity/hyperactivity symptoms in relation to inflated responsibility and obsessive‐compulsive symptoms

Smári, J., Rúrik Martinsson, D., & Einarsson, H. (2010). Rearing practices and impulsivity/hyperactivity symptoms in relation to inflated responsibility and obsessive‐compulsive symptoms. Scandinavian Journal of Psychology, 51, 392–397. The aim of the study was to investigate potential precursors of inflated responsibility (responsibility attitudes) and obsessive‐compulsive (OCD) symptoms. It was argued that both parental overprotection and impulsivity, separately and in interaction with each other, contribute to inflated responsibility and OCD symptoms. In a large sample of young adults (N = 570), self‐report measures of OCD symptoms (OCI‐R), responsibility attitudes (RAS), anxiety/depression (HADS), rearing practices (EMBU), present and past impulsivity/hyperactivity symptoms (IMP/HY) were administered. Overprotection as well as IMP/HY were found to predict OCD symptoms as well as inflated responsibility. Finally, a significant interaction was found between IMP/HY and overprotection with regard to both OCD symptoms and inflated responsibility. This effect reflected that IMP/HY was more strongly related to OCD symptoms and responsibility in people who had not been overprotected than in people who had been. Conversely overprotection was related to OCD symptoms and responsibility in people low but not in people high in IMP/HY. The results seem to indicate that the inadequacy between offer and need for parental control may play a role in the development of OCD symptoms.     

Context-based variations in EFL teachers’ reflection: the case of public schools versus private institutes in Iran

The aim of the present study was twofold: examining the effect of contextual differences on the degree of English as a foreign language (EFL) teachers’ involvement in reflection and exploring context-related factors that may help/hinder the reflection process. A mixed-methods quantitative-qualitative procedure was adopted. Eighty-five Iranian EFL teachers (41 teaching in public schools and 44 working in private language institutes) completed the English-language teaching reflection inventory developed by Akbari, Behzadpour, and Dadvand (2010 Akbari, R., Behzadpoor, F., &; Dadvand, B. (2010). Development of english language teaching reflection inventory. System, 38, 211–227.10.1016/j.system.2010.03.003[Crossref], [Web of Science ®] , [Google Scholar]), with 10 of the participants attending a follow-up interview too. The results of multiple sets of independent samples t-tests showed that teachers in the private sector reported significantly more active involvement in lower levels of reflection (i.e. practical, cognitive, and affective reflection), while no measurable difference was detected between the two groups in terms of higher levels of reflection (i.e. metacognitive and critical reflection). Analysis of the interview data further revealed that teachers’ involvement in reflection was influenced by five main context-specific factors namely, knowledge of reflection, institutional demands, teachers’ attitude toward teaching, availability of resources, and collegial support. The implications of the findings for educational policymakers and teacher educators were discussed and suggestions were provided for future research.     

Ignorance is bliss: the role of observer expectation in dynamic spatial tuning of the attentional focus

When two sequential targets (T1, T2) are inserted in an RSVP stream of distractors, perception of T2 is impaired at intertarget lags shorter than 700 msec. Paradoxically, this deficit disappears when T2 is presented directly after T1 (lag-1 sparing). Visser, Bischof, and Di Lollo (1999) found that lag-1 sparing occurs only when T1 and T2 are presented in the same stream. In contrast, Shih (2000) obtained lag-1 sparing with targets insepa-rate streams. Four experiments addressed this inconsistency and revealed lag-1 sparing with targets in different streams, but only when observers had no foreknowledge of T1's location. We hypothesized that when T1 location is known, attention is focused narrowly on that stream; if T2 then appears in the other stream it is missed, and lag-1 sparing does not occur. When T1 location is not known, attention is focused broadly, encompassing both streams, and lag-1 sparing ensues.     

Are spatial selection and identity extraction separable when attention is controlled endogenously?

Visual search for a target involves two processes: spatial selection and identity extraction. Ghorashi, Enns, and Di Lollo (2008) found these processes to be independent and surmised that they were carried out along distinct visual pathways: dorsal and ventral, respectively. The two experiments that are described in the present article evaluated this hypothesis. Attentional-blink methodology was combined with voluntary spatial cuing in a visual search task: Intertarget lag was used to manipulate identity extraction; predictive cues were used to signal target locations. Central digit cues in Experiment 1 required participants to identify digits before voluntarily directing attention to a corresponding location, whereas flashed dots in Experiment 2 (indicating an opposite location) required attentional redeployment without prior cue identification. Consistent with the dual-pathway hypothesis, cuing was impaired only when the first target and the number cue competed for ventral-pathway mechanisms. Collectively, the results support the dual-pathway account of the separability of spatial selection and identity extraction.     

Visual search is postponed during the attentional blink until the system is suitably reconfigured

J. S. Joseph, M. M. Chun, and K. Nakayama (1997) found that pop-out visual search was impaired as a function of intertarget lag in an attentional blink (AB) paradigm in which the 1st target was a letter and the 2nd target was a search display. In 4 experiments, the present authors tested the implication that search efficiency should be similarly impaired (steeper search slopes at shorter lags). A conventional AB deficit was found, but, contrary to expectations, search slopes were invariant with lag. These results suggest that no search can be carried out during the period of the AB. Instead, the search is postponed until after the 1st target has been processed. The authors conclude that efficient visual search cannot be carried out unless the visual system is configured appropriately for the search task. If the initial configuration is inappropriate, processing of the 2nd target is held in abeyance until the system has been suitably reconfigured.     

The attentional blink: Resource depletion or temporary loss of control?

Identification of the second of two targets is impaired if it is presented less than about 500 ms after the first. Theoretical accounts of this second-target deficit, known as attentional blink (AB), have relied on some form of limited attentional resource that is allocated to the leading target at the expense of the trailing target. Three experiments in the present study reveal a failure of resource-limitation accounts to explain why the AB is absent when the targets consist of a stream of three items belonging to the same category (e.g., letters or digits). The AB is reinstated, however, if an item from a different category is inserted in the target string. This result, and all major results in the AB literature, is explained by the hypothesis that the AB arises from a temporary loss of control over the prevailing attentional set. This lapse in control renders the observer vulnerable to an exogenously-triggered switch in attentional set.     

Dual imputation model for incomplete longitudinal data

Missing values are a practical issue in the analysis of longitudinal data. Multiple imputation (MI) is a well‐known likelihood‐based method that has optimal properties in terms of efficiency and consistency if the imputation model is correctly specified. Doubly robust (DR) weighing‐based methods protect against misspecification bias if one of the models, but not necessarily both, for the data or the mechanism leading to missing data is correct. We propose a new imputation method that captures the simplicity of MI and protection from the DR method. This method integrates MI and DR to protect against misspecification of the imputation model under a missing at random assumption. Our method avoids analytical complications of missing data particularly in multivariate settings, and is easy to implement in standard statistical packages. Moreover, the proposed method works very well with an intermittent pattern of missingness when other DR methods can not be used. Simulation experiments show that the proposed approach achieves improved performance when one of the models is correct. The method is applied to data from the fireworks disaster study, a randomized clinical trial comparing therapies in disaster‐exposed children. We conclude that the new method increases the robustness of imputations.     

How do Iranian women from Rafsanjan conceptualize their sexual behaviors?

In Iran, women’s sexual behaviors have not been studied in detail. The aim of this study was to explore the sexual meanings generated through the lived experience of women residing in Rafsanjan, a city in the Kerman province, where interviews and focus group discussions were conducted with 51 Iranian women. Content analysis was adopted to extract the meanings and perceptions. We categorized the findings into three aspects: sexual capacity, motivation, and performance. Sexual desire was the most important concept that women used when they were referring to their sexual capacity. Marriage was the main institution in which women’s motivation for sexual relationships and encounters resided, and “the priority of men’s sexual needs and characteristics” was identified as the core principle of marriage. The concept of sexual performance was more salient and tied to the husband’s sexual initiation. Analyzing the women’s narratives revealed that women’s sexual self-understandings and their sexual behaviors are strongly determined by “androcentricity”, this being relevant both to sexuality education and reproductive health. Recognition of this issue will facilitate understanding of the cultural foundations of sexuality among Iranians and help health providers in suggesting culturally appropriate and compatible forms of health care.
