The differential effects of age and first grade schooling on the development of infralogical and logico-mathematical concrete operations

Using the “between-grade levels” regression discontinuity design, this study examined the hypothesized differential sensitivity of logico-mathematical (LM) and infralogical (IL) operational tasks to the effects of chronological age and first grade schooling in a sample of 580 1st and 2nd grade Israeli children. The results indicate that the development of logico-mathematical operational skills (classification, class inclusion and transitivity) is mainly attributable to schooling. In contrast, the effect of schooling on the development of conservation of mass, liquid quantity and number (clearly an infralogical task) is negligible; acquisition of conservation is almost exclusively due to maturation and out-of-school experiences. The results support the theoretical predictions derived from French-Swiss research of the last two decades and are inconsistent with claims regarding the specificity of schooling effects to tasks that are taught in school.     

Awareness of the origin of knowledge predicts child witnesses' recall of alleged sexual and physical abuse

Children who understand that knowledge may have different origins produce more information in their free‐recall accounts than children who are less aware of source. We examined whether the tendency to make knowledge attributions was related to the number and proportion of details elicited from child witnesses using open‐ended invitations and whether this relationship varied depending on the number of incidents of abuse reported. The tendency to make knowledge attributions was measured in the presubstantive portion of protocol‐guided interviews with 3‐ to 11‐year‐old alleged victims of abuse. Hierarchical regression analyses revealed that the production of knowledge attribution details was positively related to the proportion of substantive episodic details produced by 3‐ to 6‐year‐olds recalling a single incident and by 3‐ to 11‐year‐olds recalling multiple incidents of abuse. Presubstantive source details were also positively correlated with the amount of source information recalled about incidents of abuse. These findings remained significant after controlling for the children's verbosity, the relative prominence of open‐ended invitations, and the children's ages. © 2003 US Government work.     

Changes in Interviewers' Use of Supportive Techniques during the Revised Protocol Training

Summary: Although many children are reluctant to disclose abuse due to embarrassment, fear, and the anticipation of negative consequences, researchers have only recently begun to examine whether forensic interviewers can be trained to manage children's reluctance. In this study, the supportiveness of 53 experienced interviewers was assessed in their interviews with 321 3‐ to 14‐year‐old alleged victims, each conducted during the course of training to use the Revised Protocol (RP). The use of support increased, especially between levels evident at baseline and in the last two interviews assessed. Over time, instances of inadequate support and insensitivity to children's reluctance became less common. Younger children received proportionally more support, including inadequate support, than older children. The RP training did not affect the extensive use of free recall‐based questions. Findings highlight the benefits of continued supervision and training.Copyright © 2017 John Wiley & Sons, Ltd.     

The influence of the menstrual cycle on reactivity to a CO2 challenge among women with and without premenstrual symptoms

Clinically significant premenstrual symptoms (PMS) is conceptualized as a depressive disorder in DSM-5, however, it may share pathophysiological processes with anxiety- and fear-related disorders. Specifically, women with PMS panic at higher rates during biological challenge procedures. It is unclear if this increased interoceptive sensitivity is a general vulnerability or specific to the premenstrual phase. The current study examined the role of menstrual cycle phase on reactivity to a CO₂ challenge among women with (n = 11) and without (n = 26) clinically significant PMS (N = 37). During the late follicular phase (days 6–12), women with and without PMS responded similarly to the CO₂ challenge, whereas during the premenstrual phase (within 5 days before menses), women with PMS reported significantly more intense panic symptoms in response to the challenge than women without PMS. Vulnerability to panic in women with PMS may be specific to the premenstrual phase. Potential psychological and neurobiological mechanisms underlying this phenomenon are discussed.     

Perceived group variability and dispositional need for closure

Based on the closure motivation theory proposed by Kruglanski and Webster (1996), it was hypothesized that the extent of perceived variability of target group members would be related to dispositional need for closure. Israeli teachers (n = 160) judged their professors by means of two methods and answered the need for cognitive closure questionnaire (NFCS, Webster & Kruglanski, 1994). The findings show that need for closure is related to social judgment. The perception of participants high in need for closure was less differentiated and more extreme, in comparison to participants low in need for closure. Findings also yielded that measures of variability are method dependent.     

The “Sprinter effect”: When self-control and involvement stand in the way of sequential performance

This research examines the joint effect of dispositional self-control and situational involvement on performance in two successive resource-demanding tasks. We demonstrate that being highly involved and having high self-control facilitates high performance in the first task but, contrary to intuition, may jeopardize performance in a second, unexpected task. We term this the “sprinter effect” and demonstrate it in both lab and field settings. We further explore how a “marathon” mindset can debias this effect.     

The sense of self-efficacy of aspiring principals: exploration in a dynamic concept

The main purpose of this longitudinal study was to conceptualize the self-efficacy of aspiring principals as a dynamic concept. This study aimed to explore the structure and relations between the components of self-efficacy and to determine the nature and direction of change in the perceived self-efficacy of aspiring principals following a 2-year training program. The study was based on Facet Theory (Gutman, Psychmetrika 33:469–506, 1968), but also included some traditional statistics. The present study was carried out in two stages during 2005–2007. One-hundred and fifty aspiring principals from five academic colleges and universities in Israel who participated in a 2-year training program completed the same self-efficacy questionnaire during the first month of the program (October 2005—stage 1 and during the last month of the program (May 2007—stage 2). The nature as well as the direction of the aspiring principals’ perceived self-efficacy changed following the 2-year training program. The perception of the nature of the principal’s role remained unchanged.     

Love alters autonomic reactivity to emotions

Periods of bond formation are accompanied by physiological and emotional changes, yet, little is known about the effects of falling in love on the individual's physiological response to emotions. We examined autonomic reactivity to the presentation of negative and positive films in 112 young adults, including 57 singles and 55 new lovers who began a romantic relationship 2.5 months prior to the experiment Autonomic reactivity was measured by Respiratory Sinus Arrhythmia (RSA) to two baseline emotionally neutral films, two negative films, and two positive films. Results demonstrated that RSA in singles decreased during the presentation of negative emotions, indicating physiological stress response. However, no such decrease was found among new lovers, pointing to more optimal vagal regulation during the period of falling in love. Autonomic reactivity, indexed by RSA decrease from the positive to the negative films, was greater among singles as compared to lovers, suggesting that love buffers against autonomic stress and facilitates emotion regulation. Findings suggest that vagal regulation may be one mechanism through which love and attachment reduce stress and promote well-being and health.     

The relations between preferences for using abilities, self-estimated abilities, and measured abilities among career counseling clients

The present research investigated the relations among the declared preferred degree for using career-related abilities in one’s future career, self-estimates of these abilities, and measured abilities in a sample of 201 career-counseling clients. The highest correlations (range .57-.65) were found between the preferred degree for using an ability and the self-estimates of the ability. However, the direction of the gap between self-estimates and preferred degree of use varied among clients and among abilities. Clients also varied in the pattern of differences between their measured abilities and self-estimates, with 69% of the clients overestimating their abilities, while only 9% underestimated them. The hypothesis that self-estimate mediates the relation between one’s preference for using an ability and the respective measured ability was supported. The correlation between a client’s measured ability and preferred degree of use was higher among clients with a fairly accurate self-estimate than among those whose self-estimates were biased. Implications for research and counseling are discussed.
